Σε ένα τελευταίο κεφάλαιο, επιχειρείται μια σύνθεση της ιστορίας αυτής, μέσω μιας συγκριτικής προσέγγισης που εντοπίζει τις συγκλίσεις και τις αποκλίσεις, έτσι όπως αυτές καταγράφονται κατά την ιστορική διαδρομή των θεσμών αυτών.
Kamberidou I. BRIDGES TO UNDERSTANDING: INTEGRATION AND INCLUSION THROUGH SPORT. Presentation at the European Sociological Association (ESA RN35) Midterm Conference Sociology of Migration after the 2015 “migrant crisis”, in collaboration with the National and Kapodistrian University of Athens (NKUA), Nov. 27-28, 2025, Athens GR [Internet]. 2025. Publisher's VersionAbstract
Can sport act as a mediator between cultures? Can sport serve as a tool for social inclusion? Is the social space of sport providing the means for moving from integration to inclusion? Are team sports and physical activity facilitating refugee and migrant integration, to wit providing migrants, refugees and asylum seekers with a form of support in regaining and maintaining their mental health and well-being? This paper argues that the social space of sport offers a platform, a bridge and a stage—for vulnerable social groups—to promote social integration and subsequently inclusion. In sharing personal stories about refugees and displaced communities, athletes have been challenging stereotypes and encouraging their social media followers to adopt more inclusive attitudes. This paper examines grassroots programs and projects involving tens of thousands of participants around the globe from educators, visionaries, volunteers, and diverse stakeholders, who are using sport to promote social inclusion. Moreover, a wide variety of organizations have been using the power of play and games to nurture peacemaking across divided communities; to ensure visibility; to promote intercultural awareness and gender equality; to eliminate racism and violence in schools and communities. Policy makers claim sport contributes to a wide range of ideals such as intercultural understanding, reconciliation, and integration. In Greece, for example, the Ministry of Labor and Social Affairs includes sport, as a tool to promote social justice, in the current National Action Plan for Gender Equality (NAPGE). Remarkable results have been documented in bridging social inequality gaps through sport.
Keywords: sport agency, athlete activism, visibility, integration, inclusion, gender, refugee, migrant, xenophobia
The increasing frequency and severity of extreme storms and floods in the Eastern Mediterranean under climate change pose significant challenges for modern societies. These events often trigger cascading effects that extend far beyond the immediate disaster zone, disrupting interconnected systems such as power, transportation, and communication networks. Despite advancements in flood risk management and growing awareness of cascading hazards, the mechanisms driving these interdependencies and their broader impacts remain poorly understood. This study investigates the cascading effects triggered by the catastrophic Storm Daniel, which struck Thessaly, Greece, in September 2023, as a case study to explore the nature, scale, and ways of impact propagation.This work also provides an analysis of cascading effects, based on evidence on historical storm and flood disaster impacts in the Mediterranean region, identifying the interactions between primary hazards (flooding, landslides, erosion) and secondary consequences as well as the diverse sectors that suffer impacts. The analysis reveals different propagation mechanisms of these effects, highlighting the vulnerability of interconnected systems as well as the vulnerability of the natural and the built environment. The cascading effects identified underscore systemic risks of modern societies posed by extreme events, particularly in urban areas with dense, interdependent, and critical infrastructure.The findings contribute to the growing body of literature on cascading disasters, addressing critical knowledge gaps in understanding how extreme weather events propagate through modern societal systems. These insights are particularly relevant in the context of climate change, which is expected to amplify the frequency and intensity of such events.
Flash floods have been responsible for some of the most catastrophic events globally. The extensive range of effects and the varying severity of impacts present significant challenges in accurately understanding the damage caused by a flood event, thereby hindering our capacity to predict future consequences. When evaluating flood impacts and their severity, most existing approaches rely on qualitative descriptions (e.g., major, catastrophic, etc.) or examine the impacts from a single perspective or discipline, such as economic losses. In this study, the Flash Flood Impact Severity Scale (FFISS) is employed to evaluate, map, and categorize the impacts of two flash floods that occurred in the Lilas River in Greece in 2009 and 2020. The goal of this application is to analyze the varying severity levels and how one flood event can influence the impacts of a subsequent event. The methodology involved extensive fieldwork, including the collection of ground-based and aerial observations using UAV technology to document the impacts. These observations were subsequently georeferenced, followed by applying the Flash Flood Impact Severity Scale (FFISS) and creating detailed maps to assess and evaluate the severity of impacts associated with the two flood events. The results indicate that, despite the higher water levels during the second flood, areas previously affected show lower severity values. This reduction is attributed to the community’s gradual adaptation, improvements in infrastructure, and significant local widening of the river channel. Conversely, newly flooded areas during the second event exhibit high severity levels. Overall, applying the FFISS reveals spatial patterns of impact severity, offering insights into the local nature of floods while suggesting a potential reduction in overall risk during the post-flood period.
We use the Worldwide Bioclimatic Classification system to identify changes in the bioclimatic characteristics of Greece between the present and the recent past, by comparing two reference periods: 1961-1990 and 1991-2020. This classification system, developed by Rivas-Martínez et al. (2011), defines the relationship between climatic variables, expressed through bioclimatic indices, and the corresponding distribution of natural vegetation. It generates distinct climatic units known as isobioclimates, which represent specific combinations of macrobioclimates, thermotypes, and ombrotypes. These isobioclimates link climate to ecosystems and allow the characterization of environmental diversity across spatial and temporal scales. The climate input for the system consists of mean, maximum, and minimum monthly temperatures and accumulated monthly precipitation. For this study, we use the ERA5-Land monthly mean data sets from the Copernicus Climate Data Store (CDS), averaged over the two study periods. Calculation of bioclimatic indices and mapping of the isobioclimates are performed using ArcGIS. Preliminary results indicate a shift in the isobioclimatic structure of Greece towards warmer thermotypes and drier ombrotypes. These changes are mostly evident in southern and lowland regions and may reflect increasing aridity and temperatures, suggesting an intensification of ecological stress and wildfire risk, with potential consequences for biodiversity. This work will be extended with the use of regional climate model projections to explore possible future bioclimatic changes in Greece, that will help to assess how climate change may affect vegetation types and inform strategies for ecosystem management in the coming decades.
Extreme weather events, increasingly frequent in the Mediterranean due to climate change, pose significant risks by triggering hydrogeomorphic processes such as slope failures. These phenomena, particularly prevalent in tectonically active and steeply sloped coastal areas, present challenges for monitoring due to their spatial and temporal dynamics.Unmanned aerial systems (UAS) and advanced photogrammetric techniques, including structure-from-motion (SfM) and multi-view stereo (MVS), have emerged as transformative tools for capturing high-resolution terrain data. This study employs UAS-aided photogrammetry alongside change detection methods, such as digital elevation models of differences (DoD) and cloud-to-cloud distance (C2C), to analyze geomorphic changes induced by extreme storms in highly visited and geologically dynamic coastal areas in Greece.The findings reveal the utility of UAS in providing detailed morphometric measurements, delineating areas of erosion and deposition, and identifying high-risk zones. These capabilities facilitate a deeper understanding of geomorphic processes, enabling informed risk assessment and management strategies. The study underscores the potential of integrating UAS and photogrammetry for continuous monitoring in regions with high socioeconomic and environmental value. This approach not only supports sustainable development by minimizing disruptions but also enhances safety standards in vulnerable, high-exposure coastal areas. Through this methodological framework, the research contributes to addressing the pressing need for resilient hazard management in the context of evolving climatic conditions.

The paper is an attempt to constructively use the differences between Science, led by Physics, on one hand and Biology on the other. More specifically, the common framework of STEM teaching is encouraged as a teaching tool for teaching concepts related to the epistemology of the two disciplines, through their epistemological differences. As such disparities, the following are proposed: The existence of a unifying theory in their teaching, and the absence of "universal" laws in Biology. Furthermore, the dissimilar roles played among them by the experiment, mathematics and history. In addition, it is commended the difference in the meanings of the concepts "Social Implications" and "Social Science", together with the meaning of the essentialism in Physics, as opposed to the non-typological "population perspective" in Biology, where the endless, random errors and deviations (mutations) are the universal driving force, that prevails behind all biological phenomena.
We find ourselves in an ever-evolving environment, where the past fifty years have marked a pivotal moment in scientific thinking. This shift is particularly evident in the scientific approach to analyzing natural-induced hazards. Geohazards annually contribute significantly to loss of life and property, with mass movements standing out as widespread occurrences globally. The study of extreme events and their repercussions on landscape stability is a critical area in environmental research. In this paper, we showcase the advancements in the integration of Artificial Intelligence (AI) and Remote Sensing (RS) for improved landslide assessments, leveraging developments in Earth Observation (EO) data analysis. We highlight the application of Object-Based Image Analysis (OBIA), which have not traditionally been tailored for landslide studies but have proven effective in this context. The framework enables the translation of complex real-world landslide scenarios into analyzable objects through segmentation algorithms, applying subsequent classifications via rule-based or advanced Machine Learning (ML) algorithms. We demonstrate how ML has the potential to revolutionize geoscience data analysis and address major societal concerns presented by landslide hazards by tapping into the vast reserves of geoscience data. ML algorithms, particularly Random Forest (RF), integrated into an Object-Based Image Analysis (OBIA) workflow, demonstrated adaptability for sub-zone landslide mapping on a local scale. Given the increasing frequency of extreme meteorological events driven by climate change, the integration of UAV datasets, Structure from Motion (SfM), and advancements in OBIA and AI can respond effectively by enabling precise and accurate analysis of landslide and rockfall failures. Our results affirm that rotational landslides and their thematic sub-zones were adequately recognized and mapped through the ML procedure.
Plastiras artificial lake is formed upstream of an 83 m-high arched dam, at an altitude of 795.20 m above msl. A hydroelectric power plant constructed back in 1959, started functioning in 1960 with an average annual electricity production of 180 GWh. Moreover, its water provides potable supply, after treatment, to surrounding towns and essential agricultural irrigation to 140,000 acres of land. The 23.5 km² lake and its surroundings are extensively used for environmental recreational activities and the local ecosystem is sensitive to human activities and environmental factors.Recently the region was affected by two extreme weather events, in 2020 and 2023, evidently causing extensive mass wasting phenomena in the surrounding drainage basins and torrent discharge points into the lake. Especially after the “IANOS” Medicane (September 17-18, 2020), a systematic monitoring of the lake and its drainage was decided. A synergy of methodologies with state-of-the-art equipment was used, to evaluate the volumes of terrigenous sediment brought into the lake, drastically reducing the water storage capacity of the dam. The reference dataset was a single and multibeam survey carried out back in 2009, accompanied by a photogrammetric mapping of the lake coast at the maximum lake water level.Our 2023 surveys encompass more than 14,000 images which were acquired with a Trinity F90 UAS, flying at a relative height of 160 meters, covering a 200-meter-wide zone around the coast of the lake, with a 70% overlap between the images. Image capturing of the latter took place during the lowest lake water level so that most of this zone would be revealed from the water's surface. The establishment of 15 Ground Control Points (GCPs) at certain locations around the lake increased the spatial credibility of the extracted 2.5 cm resolution Digital Terrain Model. For co-registration reasons, the same GCPs were also used as references during the multibeam survey, which was conducted at transects parallel and vertical to the shoreline routes, 20-90 meters apart, pending on the lake depth, to achieve a complete swath coverage of the lake bottom. The multibeam-sounding survey was carried out at near maximum lake water level, with continuous hourly monitoring of the water level and the water speed of sound.Both methodologies resulted in point-clouds which were unified, and a DTM of the entire lake bottom was constructed, representing the full extent of the water body during the highest water level. The latter was compared to the 2010 dataset and a significant change in the water volume was detected reaching almost 4 million m3. This is clearly related to the volume of sediments brought into the lake, by both sediment gravity flows entering the lake especially within the torrent inlets along the west coast while finer suspended sediment mostly settles in the deepest areas towards the dam.
The Eastern Anatolia suffered devastation following two major earthquakes on 6 February 2023 causing collapse of numerous structures and resulting in tens of thousands of human casualties, injuries, and displacements. This research endeavors to elucidate factors related to building properties and earthquake environmental effects (EEEs) that control the grade and distribution of structural damage in southeastern Turkey. The outcomes delineated herein originate from post-event field surveys conducted by the authors shortly after the earthquakes. The field surveys encompassed geological mapping techniques alongside novel methodologies, such as the utilization of Unmanned Aerial Systems (UAS).In terms of building construction characteristics, deficiencies such as inadequate compliance with building codes, arbitrary urban planning solutions, and inferior construction practices represent primary factors that contributes significantly to the disaster. Regarding geological factors, both primary and secondary EEEs played a significant role in controlling the severity and distribution of building damage. Primary EEEs, in particular coseismic surface ruptures along segments of the East Anatolian Fault (EAF), intersected with urban regions exhibited severe to severe structural damage (e.g. Gölbaşı, Balkar, Sekeroba, Nurdağı, İslahiye, Hassa towns etc.). Liquefaction along with lateral spreading and subsidence near water bodies (sea, existing and former lakes and rivers in the affected area) resulted in damage indicative of compromised building foundation load-bearing capacity (e.g. İskenderun, Gölbaşı and Antakya cities). Typical damage included sinking and tilting of buildings, damage due to pounding of adjacent structures, as well as outspread multi-layer and pancake-type collapse. Earthquake-triggered landslides (ETILs) predominantly affected mountainous and semi-mountainous villages. The collision of the mobilized rock fragments with adjacent structures and the presence of structures within the landslide boundaries are the main mechanisms of building damage due to ETILs. The synergy of high landslide susceptibility and liquefaction potential resulted in destruction in several urban centers of the earthquake-affected area (e.g. Kahramanmaraş city).
Disasters arising from geophysical hazards have the potential to trigger extensive structural damage upon the built environment within the impacted area. A substantial proportion of debris generated from earthquakes is a consequence of structural collapse during the ground motion, coupled with the urgent demolition of severely damaged and unstable structures in the course of emergency response and recovery. Among the foremost and pivotal measures undertaken during disaster management is the effective management of the generated debris. This task stands as one of the paramount challenges faced by those involved, given its inherent hazards to both the natural environment and public health. These hazards emanate from the presence of hazardous materials within debris from collapses and demolitions.Numerous challenges and associated hazards emerged in southeastern Turkey after two devastating earthquakes on 6 February 2023 with Mw=7.8 and Mw=7.5 respectively. These seismic events affected a densely populated region encompassing 11 provinces, which included numerous sizable urban centers, such as large cities and towns, along with extensive rural areas comprising countless villages.The convergence of intense ground motion, accompanied by the occurrence of widespread primary effects, such as coseismic surface ruptures, and the triggering of secondary effects, including mainly but not limited to liquefaction and landslides, culminated in the total or partial collapse of tens of thousands of structures and the extensive leveling of residential areas. This fact gave rise to a debris volume deemed the largest since the 1994 Northridge earthquake and challenging to manage, even within well-organized nations.In the course of post-event field surveys conducted by the authors within the earthquake-stricken area, various disposal sites established in the most severely affected provinces were identified and assessed for suitability. The field surveys included the utilization of Unmanned Aircraft Systems (UAS) in the disaster-affected areas, complemented by the examination of satellite imagery in the laboratory to evaluate the characteristics of the sites and their immediate surroundings and to monitor the ongoing debris management activities.The findings indicate that none of the identified sites possessed attributes qualifying them as safe for the treatment and disposal of earthquake debris. Primarily, this inadequacy is attributed to their close proximity to areas densely populated with thousands of residents who engage in daily activities. Furthermore, from the environmental viewpoint, these sites operated either within or in close proximity to surface water bodies. This situation reveals a rush for rapid debris removal and recovery resulting in serious omissions in the preparation of disaster management plans and concessions in their implementation. Consequently, recommendations for effective debris management measures are also proposed in the context of this research based on existing scientific knowledge and operational expertise.
On September 4, 2023, Storm Daniel moved inland from the Ionian Sea, intensifying due to the warmth of the post-summer Mediterranean Sea, resulting in intense rainfall and thunderstorms over the Balkans. Central Greece was particularly affected, experiencing the highest daily rainfall totals recorded in the region.The storm caused widespread devastation, especially in the Thessaly region, with significant impacts including intense erosion, mass movement phenomena triggered by rainfall, damages from strong winds, inundation, agricultural land damage, loss of life and injuries, impacts on residences and businesses, as well as a substantial toll on the environment and cultural sites.This study focuses on Storm Daniel and its effects in Thessaly, Greece, by creating a database of distinct impact elements based on field surveys and public records. Through this archive, the study explores the range of its impacts, developing a systematic categorization to provide an in-depth understanding of the types and mechanisms of these impacts.Examining extreme storms through post-flood surveys and emphasizing their impacts can enhance our comprehension of associated risks. This knowledge will facilitate more accurate predictions and strategic planning for such events, contributing to improved emergency management and recovery efforts. Anticipating the impacts becomes crucial, particularly in the context of the projected increase in the frequency of such events due to climate change, thereby strengthening our preparedness.
Kalymnos Island features extensive vertical limestone cliffs that span throughout the entire onshore area, establishing it as one of the world's premier locations for sports climbing. Drawing thousands of tourists and climbers annually, Kalymnos captivates with its unparalleled natural beauty and unique geomorphological relief. The absence of vegetation and the prevalence of large limestone vertical cliffs contribute to a distinctive geological setting, showcasing detached boulders throughout the island and positioning it as an ideal site for studying rockfall events worldwide. To investigate this peculiar geological landscape, contemporary close-range remote sensing techniques such as UAS images photogrammetric processing, terrestrial LiDAR point clouds, and high-resolution satellite imagery within a GIS platform are employed. This integrated approach facilitates the creation of detailed terrain models and enables the identification of spatial boulder distribution on the downslope areas of steep carbonate cliffs. Moreover, the diachronic study of the detected high-risk locations delineated the surface changes at the foot of the steep slopes where several back analyses were performed. Utilizing these quantitative techniques provides valuable information for designing protective measures for the stability of the slopes, highlighting the safe climbing routes for the athletes and the infrastructure at the cliff bases. Strategies involve anchoring individual rock blocks, removing unsafe rock masses, and implementing restraining nets or dynamic rockfall barriers at strategic locations along the route trail to mitigate risks effectively.

On 6 February 2023, the Eastern Anatolia experienced significant devastation due to two major seismic events, leading to the collapse of hundreds of thousands of structures and causing tens of thousands of human casualties, injuries, and homeless people. The substantial magnitude of these impacts is attributed to the extensive occurrence of heavy and very heavy structural damage, categorized as damage grades 4 and 5 according to the European Macroseismic Scale EMS-98, within the earthquake-affected area.The discernible factors contributing to the disaster encompassed the substantial magnitude of the earthquakes, the occurrence of the initial seismic event during nighttime, thereby locating a considerable portion of the population within their residences, and the demographic attributes of the region characterized by densely constructed and populated zones, coupled with the close proximity of numerous residential areas to the ruptured faults. Additionally, the confluence of significant factors, closely associated with the seismotectonic context of the region, the effects of earthquake environmental effects, and the characteristics of the impacted structures, culminated in one of the most extensive earthquake disasters in the recent history of Turkey.This study aims to highlight the factors controlling associated with building properties and the manifestation of earthquake environmental effects that govern the severity and spatial dispersion of structural damage within the earthquake-affected regions under study in the southeastern Turkey. The findings presented herein derive from field surveys undertaken by the authors in the immediate aftermath of the seismic events (7th to 11th February) and subsequently, almost two months later (31st March to 6th April). The field surveys included conventional techniques of geological mapping alongside innovative methodologies, including the deployment of Unmanned Aerial Systems (UAS).With regard to building construction characteristics, insufficient adherence to building codes, arbitrary urban planning solutions, and substandard construction practices constitute primary deficiencies contributed to the disaster. Concerning geological factors, the generation of both primary and secondary earthquake environmental effects significantly influenced the intensity and distribution of damage. Locations where coseismic surface ruptures intersected with built-up areas exhibited heavy to very heavy structural damage, as evidenced along the ruptured segments of the East Anatolian Fault Zone. Liquefaction proximal to water bodies resulted in damage indicative of building foundation load-bearing capacity. Earthquake-triggered landslides predominantly impacted mountainous and semi-mountainous villages and areas characterized by pre-existing susceptibility. The substantial susceptibility to EEEs generation was extensively corroborated in numerous cases, leading to widespread damage. The presented information highlights the pivotal role of such studies in informing hazard mitigation and facilitating disaster risk reduction measures.
The evolution of technology, particularly the integration of Unmanned Aerial Systems (UAS), earth observation datasets, and historical data such as aerial photographs, stand as fundamental tools for comprehending and reconstructing surface evolution and potential environmental changes. In addition, the active geodynamic phenomena in conjunction with climate crisis and the increasing frequency of extreme weather phenomena can cause abrupt events such as rockfalls and landslides, altering completely the morphology on both small and large scales.This study deals generally with the temporal evolution of landscapes and specifically focuses on the detection and quantification of a significant rockfall event that occurred at Kalamaki Beach on Zakynthos Island, Greece – a very popular summer destination. Utilizing UAS surveys conducted in July 2020 and July 2023, this research revealed a rockfall that has significantly altered the coastal morphology. During this period, two severe natural phenomena occurred, one of which could potentially be the cause of this rockfall event. Initially, the Mediterranean hurricane (‘medicane’) ‘Ianos’ made landfall in September 2020, affecting a large part of the country including the Ionian Islands. The result was severe damage to property and infrastructures, along with human casualties, induced by intense precipitation, flash flooding, strong winds, and wave action. Second, in September of 2022, an ML=5.4 earthquake struck between Cephalonia and Zakynthos Islands in the Ionian Sea, triggering considerable impact in both islands. The study employs satellite images postdating these natural disasters, to detect the source of the rockfall in Kalamaki Beach. Additionally, historical analog aerial images from 1996 and 2010 were used as assets for understanding the surface’s evolution. For the quantitative analysis, we applied 3D semi-automated change detection techniques such as the M3C2 algorithm, to estimate the volume of the rockfall.The results provide insights into the complex interplay between natural disasters and geological processes, shedding light on the dynamic nature of landscapes and the potential implications for visitor-preferred areas.This research not only contributes to our understanding of landscape evolution but also underscores the importance of integrating modern and historical datasets to decipher the dynamic processes shaping the Earth's surface. The methodology proposed, serves as a valuable approach for assessing and managing geological hazards in coastal regions affected by both climatic events and geodynamic activities.
Coastal cliffs are one of the cases of steep terrains naturally vulnerable to a range of erosional processes, with rockfalls emerging as one of the most prevalent and hazardous. Although predicting rockfall occurrences remains challenging due to multi-faceted triggering factors such as extreme weather events, seismic activity, erosion, and human actions, technological advancements offer promising avenues for developing more robust and effective risk assessment methodologies. Light Detection and Ranging (LiDAR), photogrammetry from Unmanned Aerial System images, and satellite imagery, coupled with the evolution of artificial intelligence, have revolutionized the field of rockfall assessment by enabling precise detection and quantification of 3D topographic changes, offering insights into rockfall dynamics.
The significance of social skills for both, integration in the labor market and job retention, has been long recognized in the international literature (Suarta et al., 2017). The need to adapt to current demands is linked with the investment in social skills (Harvey, 2010). However, recent studies suggest that social skills are increasingly rare in the job market (Schislyaeva & Saychenko, 2022). The current paper focuses on the issues surrounding the cultivation of social skills in the workplace.

Credit card customers comprise a volatile subset of a banks' client base. As such, banks would like to predict in advance which of those clients are likely to attrite, so as to approach them with proactive marketing campaigns. Neuronets have found great application in many classification problems. Credit card attrition is a poorly investigated subtopic that poses many challenges, such as highly imbalanced datasets. The goal of this research is to construct a feed-forward neuronet that can overcome such obstacles and thus accurately classify credit card attrition. To this end, we employ a weights and structure determination (WASD) algorithm that facilitates the development of a competitive and all around robust classifier whilst accounting for the shortcomings of traditional back propagation neuronets. This is supported by the fact that when compared with some of the best performing classification models that MATLAB's classification learner app offers, the power softplus activated WASD neuronet demonstrated either superior or highly competitive performance across all metrics.
“What is Byzantium” in Greek school textbooks. From the “Greek Empire” to the caging between late antiquity and early modernity .“Byzantium”, as a technical term, was coined in France of Louis XIV to describe the based in Constantinople eastern region of the Roman state, which was gradually transformed into the initially Greek-speaking and gradually Greek medieval empire. As a historical period but also as an object of scientific research, Byzantium was a problem or raised concerns for the transition from the world of antiquity to the modern Hellenism and the new Greek state. Therefore, it caused embarrassment as to how it was displayed and examined in school textbooks. Along with the development of historiography but often with epistemological ambivalence, the Byzantine Empire was treated with reservations, fabricated prejudices and expediencies. At other times, an attempt was made to elevate the imperial grandeur, referring to Greek glory and splendour. At other times, its history was squeezed between the “overemphasized” late antiquity and the changes and achievements of Western European modernity, depriving Byzantinology of its independence as a scientific field and Byzantium of its characteristics as a distinct historical era. The study outlines this multifaceted approach in Greek school textbooks, and highlights its points, compatible or incompatible with the evolution of Byzantine studies at international and national level.

Η συλλογή των δεδομένων πραγματοποιήθηκε μέσω συνεντεύξεων σε ομάδες εστιασμένης συζήτησης (focus groups). Σχηματίστηκαν τρεις ομάδες των πέντε μαθητριών και μία ομάδα των τεσσάρων. Πραγματοποιήθηκαν δύο συνεντεύξεις με κάθε ομάδα διάρκειας περίπου 30΄ η κάθε μία.
Αποτελέσματα: Οι παράγοντες που περιορίζουν ή αναστέλλουν τη συμμετοχή των έφηβων μαθητριών μπορεί να είναι ατομικοί (μεταβολή προτεραιοτήτων, έλλειψη δεξιοτήτων, ανταγωνιστικό κλίμα, εικόνα σώματος), κοινωνικοί [οικογένεια, φίλοι, συνομήλικοι/έμφυλα στερεότυπα (2)] ή περιβαλλοντικοί (είδος δραστηριοτήτων, αθλητικές εγκαταστάσεις, εκπαιδευτική πολιτική). Ως υποστηρικτικοί παράγοντες θεωρούνται (μεταξύ άλλων) η ποικιλία δραστηριοτήτων και η δυνατότητα επιλογής, η άσκηση με φίλους, η απουσία ανταγωνισμού.
Συζήτηση/Συμπεράσματα: Ο εντοπισμός και η ιεράρχηση των παραγόντων που επηρεάζουν θετικά ή αρνητικά τη συμμετοχή των έφηβων κοριτσιών στη Φυσική Αγωγή καθίσταται αναγκαίος και επιτακτικός προκειμένου να σχεδιαστούν κατάλληλες παρεμβάσεις για την αύξηση της συμμετοχής και την προώθηση της υγιούς ανάπτυξής τους.

Το σώμα κατανοείται στις κοινωνικές επιστήμες σαν αναπόσπαστο μέρος, σαν θεμελιώδης βάση συγκρότησης εαυτού και ταυτότητας. Συλλαμβάνεται σαν επιφάνεια, σαν ‘πεδίο’ και ‘μέσον’ συγκρότησης, κατασκευής, συμβολισμού και έκφρασης του εαυτού. Ενίοτε σαν βάση και άλλοτε σαν αναπόσπαστος διαμεσολαβητικός παράγοντας κατασκευής και ανα-κατασκευής ταυτοτήτων. Οι έννοιες ωστόσο εαυτός και ταυτότητα μπορούν να προσεγγισθούν ακολουθώντας ποικίλες γνωστικές διαδρομές. Στο πλαίσιο ετούτης της μελέτης η έννοια του εαυτού και των ταυτοτήτων κατανοούνται ως πολλαπλότητες των οποίων τα στοιχεία που τις συγκροτούν βρίσκονται σε διαρκή αλληλεπίδραση και αλληλοδιείσδυση. Όταν επομένως αναφερόμαστε σε όρους ‘εαυτός’ και ‘ταυτότητα’ κατ’ ουσία αναφερόμαστε σε περίπλοκα και πολυσύνθετα συστήματα τα οποία ιδιαίτερα στα ψηφιακά επίπεδα δραστηριοποίησης μας όταν μάλιστα διαδρούμε με τη διαμεσολάβηση εικονικών σωματικών αναπαραστάσεων (Avatars) άλλοτε σχετίζονται ευθέως και άμεσα με το φυσικό, το βιολογικό μας σώμα και άλλοτε όχι. Σήμερα, πολλά εικονικά περιβάλλοντα, προσομοιωμένα περιβάλλοντα πολυμέσων βασισμένα στον υπολογιστή, δημιουργώντας μια τρισδιάστατη εικόνα που φαίνεται να περιβάλλει τον χρήστη, προσφέρουν πολλές ευκαιρίες για να ζήσει μέσω εικονικών σωματικών αναπαραστάσεων, προσομοιωμένες εμπειρίες που σχετίζονται με τον αθλητισμό, όπως σκι, ποδηλασία, ιππασία κ.λπ.. Αυτό δείχνει ότι το ‘αθλητικό σώμα’, σε μια άλλη διάσταση, είναι επίσης παρόν στον εικονικό κόσμο. Ο ψηφιακός χώρος είναι ένας κατασκευασμένος με ψηφιακά-διαδικτυακά μέσα χώρος. Ένας χώρος που ταυτόχρονα παριστά και αναπαριστά. Ένας χώρος αίσθησης και (ψευδ-)αίσθησης στο πλαίσιο του οποίου διαμορφώνονται χωρικές σχέσεις, έννοιες, διαδράσεις, γεγονότα και συμβολισμοί κατ’ αναλογία και μιμητικά προς τον ‘φυσικό’ χώρο! Ένας χώρος δυνητικών εμπειριών μέσω μιας ποικιλότητας αισθητηριακών προσλήψεων δια των οποίων ο ‘άυλος’ ψηφιακός χώρος, μετασχηματίζεται σε ‘εμπειρικό’ χώρο. Αυτή η μελέτη χρησιμοποιώντας επιλεκτικά σε μια διεπιστημονική προοπτική σχετικά ερευνητικά δεδομένα από τις κοινωνικές και γνωστικές επιστήμες, αλλά και δεδομένα από τις επιστήμες των υπολογιστών τα οποία και συσχετίζει με θεμελιώδεις σκέψεις του Merleau-Ponty και του Allen Badiou, επιδιώκει να διερευνήσει το ακόλουθο ζήτημα: Εάν και πώς μπορεί να συγκροτηθεί μια εικονική αθλητική ταυτότητα σε έναν εικονικό αθλητικό χώρο, για παράδειγμα σε ένα εικονικό γυμναστήριο! Πως βιώνεται ο ψηφιακός χώρος σωματικής άσκησης ως εμπειρικός χώρος;

Στην εισήγηση γίνεται προσπάθεια ανεύρεσης του σημείου συνάντησης της Γενετικής με την Διδασκαλία της Βιολογίας με σημείο καμπής την έννοια του λάθους. Σχολιάζεται: Α) σημασία του σφάλματος (μεταλλάξεων) ως κομβικού σημείου της Εξέλιξης μέσω Φυσικής Επιλογής (ΕμΦΕ). Β) Η σημασία των λαθών ως ΕΙ των μαθητών στη διδακτική των ΦΕ/Βιολογίας. Γ) Η σπουδαιότητα της Διδακτικής των ΦΕ ως σημείου συνάντησης δύο εκ διαμέτρου αντίθετων κόσμων: του κόσμου της Φυσικής, όπου ο Δημιουργός «δεν παίζει ζάρια», με εκείνον της Βιολογίας, στον οποίο είναι το αγαπημένο Του παιχνίδι.
The coastal area of Myrtos beach, is a very popular Natura protected area at the Northern part of Cephalonia Island, in W. Greece, which suffered severe damages during the Medicane named after “Ianos”, that affected the Greek territory in September 2020. Most of the steep slope area, which hosts the road that leads to the the beach area itself were extensively covered by debris due to mudflows, interrupting aggressively the road connection with the inland network.
The use of Unmanned Aerial Systems proved to be an ideal way of mapping quite small areas, with limited access to road networks. The generation of ultra-high resolution spatial products seems to be optimal for mapping and quantifying mass movements that cover areas ranging from less than one square kilometer up to few square kilometers. The aim of such a multi-temporal study, which is described herein, contains aerial image data collection and analysis, before and after the catastrophic event. It is leading to the quantification of the surface topographic changes, by generating a time series of point clouds, after creating several terrain models along with ortho-photo-mosaics, based on Structure-from-Motion photogrammetric techniques.
The digital comparison of the co-registered photogrammetric products showed that significant surface alterations have taken place due to the 2020 Medicane. The diachronic point clouds led to the detection and quantification of elevation changes, mainly at the central part of the area of interest, whereas the elevation values of the point clouds were found rather altered, before and after “Ianos”, either positively (deposition) or negatively (erosion), delineating the areas that suffered surface changes.
Motivated by the control problem of a robot tracked vehicle, the problem of common noninteracting control with simultaneous partial output zeroing is introduced and solved for the case of multi model normal linear time invariant systems, using a regular and static measurement output feedback controller. The necessary and sufficient conditions for the solvability of the problem are established, and the general solution of the controllers is derived. The present design results are successfully applied to the two-model description of the robot tracked vehicle, through a common controller, using only measurements of the motor currents and the orientation of the vehicle. Additionally, approximate asymptotic command following is achieved. Finally, using a metaheuristic algorithm the transient behavior of the independently controlled outputs, is improved.
For the class of general neutral multi delay systems with measurable and non-measurable (unknown) disturbances, the problem of triangular decoupling with simultaneous disturbance rejection, is studied via delayless dynamic and/or static controllers, feeding back the measurement outputs and the measurable disturbances. The necessary and sufficient conditions for the problem to have a solution via delayless dynamic controllers are established and the general form of the delayless dynamic controller matrices solving the problem are derived. For the delayless static controller case, the respective solvability conditions and general controller solutions are derived.
Moscow managed to "diplomatically" contain the Baku-Yerevan-Stepanakert explosion since Russia reemerged in a dominant and decisive way as a peacekeeping military and economic actor in the Armenia-Azerbaijan dipole. In fact, Russia stopped more bloodshed, might drive it away from its "regular" ally, Turkey, and cut all ties with Azerbaijan handing it over to the West. Therefore, this explains Moscow's initiative to propose solutions to the Pashinyan government inclusive of a peaceful return of Azeri refugees from areas of Sushi, before its eventual handover to the Azeris, under the guarantee of Russia's own military presence in order to "ensure cohabitation between Armenian residents and Azeri repatriates". However, these proposals, which would have meant Artsakh's "losing" of a single province (Sushi), were not accepted by Pashinyan, precisely because of his effort to avoid all Russian presence in the region. After all, his Government's members also pushed in this direction. His mistake, however, proved to be huge and the price was paid by the unfortunate Armenians of Artsakh.
To improve the manoeuvrability of differential drive mobile robots around a straight path on a horizontal plane, an I/O decoupling control scheme is proposed through a proportional controller that uses real time measurements of the kinetic variables of the mobile robot and measurements of the orientation of the robot, received through a wireless network providing communication delays. The present control scheme is based on the linear approximant of the robot model. The I/O decoupling design requirement is proven to be always satisfied and the controller is proven to be a common controller for various values of the robot parameters The stability and asymptotic command following of the closed loop system is studied. The resemblance of the performance of the closed loop system, using the delayed controller, to the respective response of the closed loop system for zero delay, is accomplished through a metaheuristic algorithm. The efficiency of the derived controller when applied to the nonlinear model of the mobile robot is illustrated through simulations.
PI controllers are favorable for implementation in most industrial computer controller platforms as well as integrated circuit platforms. In the present paper a multivariable Proportional plus Integral (PI) controller is designed for the regulation of ethanol concentration in a continuous fermenter, being a reactor with several industrial and biomedical applications. Based upon the nonlinear model of the fermentation process, a linear approximant of the process is analytically derived. The range of accuracy of the linear approximant is determined using a mixed norm criterion. Based upon the linear approximant and a metaheuristic algorithm, a multivariable PI controller is designed in order to satisfy stability for the closed loop system, asymptotic command following for the ethanol concentration and model following of the respective closed loop linear approximant system. Performance of the proposed control scheme when applied to the original nonlinear model is satisfactory, even for large external commands.
The problem of controlling the position of a magnetically levitated ball is studied through a PD state feedback linear controller and the simultaneous satisfaction of a set of individual miscellaneous design requirements including stability, command following, model following and appropriately bounded input. The requirements are defined over the linear approximant of the magnetic levitation system. Also, for the solution of the problem, a metaheuristic algorithm, based on the linear approximant of the magnetic levitation system, is proposed. The performance of the proposed control scheme, for the resulting nonlinear closed loop system, is illustrated through a series of computational experiments.
Using the analytic finite deterministic automata models of the subsystems of an automated manufacturing system, in circular mode, the safety specifications of the system are formulated in the form of rules. The rules are translated to appropriate desired regular languages. The languages are realized in analytic forms of finite deterministic supervisor automata. The controllability of the languages, realized by the supervisors, and the nonblocking property of the resulting controlled automaton, are proven.
In the present paper, the problem of independent control of the speed and orientation of a differential drive mobile robot through wireless networks is studied. Based upon the linear approximant of the nonlinear model of the mobile robot, a multidelay linear I/O decoupling controller is designed. The controller feeds back delayed measurements of all state variables of the system. The analytic form of the precompensator matrix and a part of the elements of the feedback matrix is determined. The remaining controller parameters are metaheuristically evaluated so that appropriate delay stability margins are accomplished. The performance of the proposed control scheme is illustrated through series of computational experiments where it is observed that the nonlinear model behaves satisfactorily for large external commands and uncertain model parameters.
Οι κοινωνικά ευπαθείς ομάδες αντιμετωπίζουν μεγαλύτερο κίνδυνο για φτώχεια ή κοινωνικό αποκλεισμό σε σχέση με τον γενικό πληθυσμό, είτε λόγω ανα πηρίας, είτε λόγω ηλικίας, προέλευσης, αστεγίας, κατάχρησης ουσιών ή/και εγκλεισμού. Στις κοινωνικά ευπαθείς ομάδες εντάσσονται και παιδιά που αντι μετωπίζουν κοινωνικά προβλήματα καθώς και νέοι ηλικίας 1625 ετών που βρί σκονται εκτός εκπαίδευσης, εργασίας και κατάρτισης. Καθοριστικό ρόλο στις μορφές αποκλεισμού παιδιών ηλικίας 017 ετών διαδραματίζει το μορφωτικό επίπεδο των γονέων. Σύμφωνα με την Eurostat (2021), στην Ελλάδα σήμερα το 74.4% των παιδιών υποεκπαιδευμένων γονέων κινδυνεύει από κοινωνικό αποκλεισμό. Την εποχή του ψηφιακού μετασχηματισμού εμφανίζονται και νέα ζητήματα, προκλήσεις και κίνδυνοι για «διπλό αποκλεισμό», τόσο κοινωνικό όσο και ψηφιακό, με τις αντίστοιχες συνέπειες για τις προοπτικές εκπαίδευσης και εργασίας σημαντικής μερίδας του πληθυσμού. Στην προσπάθεια αντιμετώ πισης του κοινωνικού αποκλεισμού και πρόληψης του ‘διπλού αποκλεισμού ́, στόχος των προγραμμάτων διά βίου μάθησης είναι η αύξηση των δυνατοτή των πρόσβασης στην εκπαίδευση ειδικά για τα άτομα που βρίσκονται εκτός του τυπικού εκπαιδευτικού συστήματος. Ωστόσο, τα εμπόδια είναι σημαντικά και αφορούν διαφορετικά θεσμικά και στρατηγικά επίπεδα. Ή παρούσα εργα σία διερευνά τα παραπάνω θέματα καθώς και τις προκλήσεις και τις προοπτι κές που αναδύονται στην σύγχρονη εποχή.
Η παρούσα εργασία εστιάζει στην αξιοποίηση της σπειροειδούς μάθησης, των ομάδων κατάρτισης καθώς και της προσομοίωσης ως σημαντικών εργαλείων για την ένταξη στο χώρο εργασίας. Η εργασία αναδεικνύει τις δυνατότητες αξιοποίησης των παραπάνω μεθόδων και εργαλείων στην περίοδο της πανδημίας και της ψηφιακής αλλαγής. Παρουσιάζονται τα στάδια και οι βασικές παράμετροι της σπειροειδούς μάθησης, τα παιχνίδια προσομοίωσης στον κύκλο των διδακτικών πρακτικών και μεθόδων καθώς και οι ομάδες κατάρτισης (Τ-groups). Η εργασία προτείνει παραδείγματα και καλές πρακτικές τόσο από το χώρο της τριτοβάθμιας εκπαίδευσης όσο και από το χώρο των οργανισμών και ένα μοντέλο εκπαίδευσης προσαρμοσμένο σε πραγματικές εργασιακές συνθήκες.
Safety and reliability of gas transmission systems include efficient performance of the gas compressor stations, being indispensable parts of the distribution network. Efficient control of gas compressor stations is an important constraint of the optimization of gas transmission networks. In this paper, the model of a gas compressor station with possible recycle valve (actuator) faults is presented using finite deterministic automata. The desired performance with respect to the safe operation of the process in the case of actuator faults is formulated in the form of regular languages. The goal is surge prevention in the presence of faults. Towards this aim, a modular supervisory control scheme, also providing controller realizability and guaranteeing a nonblocking controlled system, has been developed. The implementation of the controller is accomplished in the form of Ladder Diagrams for PLC use.
The model of the AODV routing protocol, being favorable in several wireless networks (VANET, ZigBee etc.) is presented for a network with parametric number of nodes in the Ramadge Wonham (RW) framework of discrete event systems. Simulation of the automaton of the protocol, for a given four-node network, is provided. For a generic network consisting of n nodes, the goal is to introduce a first simple hierarchy of the requests of the nodes and the routing paths. To this end, a specification is introduced to express the desired hierarchy. The specification of the hierarchy is presented in the form of a simple rule. The rule is translated to a regular language. A supervisor automaton is designed to realize the desired regular language. The nonblocking property of the request flow between the nodes of the network and the satisfactory marked behavior of the controlled automaton are proved. To illustrate the effectiveness of the present control scheme, a four-node network simulation of the controlled automaton of the protocol is provided.
Cell-Free (CF) Massive MIMO (mMIMO) is a technology which can potentially augment not only the deployment of 5G, but also the deployment of "beyond 5G'' (B5G) wireless networks. The basic idea behind this “user-centric” arrangement is that many spatially dispersed access points (APs) coherently serve all nearby devices without being confined by cell boundaries. However, the cost for rolling out such systems, at a macro-level, may be significant. Radio stripes form a promising intermediate solution, which offers the potential of scalability at a reduced price. This paper investigates the uplink scenario of a CF massive MIMO (mMIMO) system, implemented with a limited-capacity radio stripe, which integrates a novel AP arrangement that fully exploits macro-diversity benefits. We also analyze a heuristic compare-and-forward (CnF) strategy, which, by comparing normalized minimum mean square error (N-MMSE) soft estimates, enables optimal dynamic cooperation clustering. Aiming at maximizing the spectral efficiency (SE) of a high percentage of users, we ensure that, under finite capacity constraints, our solution can guarantee better performance than existing radio stripe architectures when size of the system scales.
Precision Agriculture (PA) tends to become a contemporary trend nowadays, as agriculture constitutes a really big part of economy with great social impact around the world. Among the advantages of using Precision Agriculture (PA) are the decrease in cost, time and human resources.
Aerial remote sensing data processing and interpretation is a modern way of recognizing and classifying vegetation, within high resolution and precision imagery outputs, which can be utilized for further image processing and classification such as in Normalized difference vegetation index NDVI, Modified Chlorophyll Absorption Ratio Index, MCARI, and Modified Soil-Adjusted Vegetation Index, MSAVI. The application of such thematic products may lead to the best decisions for the most prominent ways of interference during the entire cultivation process. Using unmanned aerial systems (UAS), onboard sensors and GNSS for better precision and of course high residual multispectral images with several bands which can give precious information after being post processed, the data acquisition phase has become relatively easy and with the lowest cost, not to mention the frequent update upon request. In this work, we present a multispectral flying platform. The proposed solution is based on a commercial Quantum Trinity F90+ drone equipped with a combination of a high-resolution RGB camera UMC R10C and a multispectral MicaSense RedEdge-MX camera.
Η Ειρήνη Καμπερίδου, Καθηγήτρια Κοινωνιολογίας ΣΕΦΑΑ, ΕΚΠΑ μίλησε για τη γυναικεία εμπειρία και δράση (women's agency) σε εμπόλεμες ζώνες και συγκρουσιακές συγκυρίες στην ημερίδα που διοργάνωσε το Γενικό Επιτελείο Εθνικής Άμυνας (ΓΕΕΘΑ), Διεύθυνση Υγειονομικού, Τμήμα Υγειονομικής Πολιτικής και Προληπτικής Ιατρικής, υπό τον τίτλο «Διαστάσεις Ψυχικής Υγείας στις Ένοπλες Δυνάμεις». Ανέδειξε τον πρωτοποριακό και καθοριστικό ρόλο των γυναικών (του 19ου αιώνα και των αρχών του 20ου) στην επίλυση επειγόντων και συγκρουσιακών καταστάσεων, την κοινωνική μέριμνα και τη δημόσια υγεία. Η διάλεξη της κας Καμπερίδου ήταν αφιερωμένη στην επέτειο μνήμης των 100 χρόνων από τη Μικρασιατική Καταστροφή (1922-2022).

Κοινωνικό φύλο και έμφυλη ουδετερότητα στην ψηφιακή εποχή: θέματα φύλου και ισότητας στον αθλητισμό και την (Gender-neutralstandards / degenderinginsportandsociety). Εισήγηση στην Επιστημονική Ημερίδα “Αθλητική Δραστηριότητα, Σωματική Άσκηση και Φυσική Αγωγή στις Προοπτικές της 4ης Βιομηχανικής Επανάστασης: Αναστοχαστικοί Προβληματισμοί.” Διοργάνωση, Τομέας Θεωρητικών Επιστημών της Σχολή Επιστήμης Φυσικής Αγωγής και Αθλητισμού (ΣΕΦΑΑ) του Εθνικού και Καποδιστριακού Πανεπιστημίου Αθηνών (ΕΚΠΑ), 18 Ιουνίου 2022: https://hub.uoa.gr/event-athletic-activity-physical-exercise-and-physical-education/ -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ΠΕΡΙΛΗΨΗ:
Θα χρειαστούν 135,6 χρόνια για να κλείσει το έμφυλο χάσμα—να επιτευχθεί η ισότητα των φύλων σε όλους του τομείς—σύμφωνα με την τελευταία έκθεση του Παγκόσμιου Οικονομικού Φόρουμ για το παγκόσμιο έμφυλο χάσμα (Global Gender Gap Report, 2021), αν δεν μεταβληθούν ριζικά οι πρακτικές αποκλεισμού και τα κοινωνικά στερεότυπα που τις διαιωνίζουν. Στην εποχή της πανδημίας του κορονοϊού αυξήθηκε 36 έτη (κατά μία γενιά) η γεφύρωση το παγκόσμιου έμφυλου χάσματος: από 99,5 έτη σε 135,6. Η χώρα μας καλύπτει το 68,9% του έμφυλου χάσματος και κατατάσσεται στην 98η θέση σε σύνολο 156 χωρών. Οι μεγαλύτερες διαφορές (υποεκπροσώπηση των γυναικών) εντοπίζονται στην Οικονομία και την Πολιτική, ενώ στην Υγεία και την Εκπαίδευση η Ελλάδα παρουσιάζει εξαιρετικές επιδόσεις στους σχετικούς δείκτες (96,6%, και 99,4%, αντίστοιχα). Παρά την πρόοδο στην Υγεία και την Εκπαίδευση οι γυναίκες αντιμετωπίζουν μειωμένη πολιτική συμμετοχή, οικονομικά εμπόδια, και προκαταλήψεις/έμφυλα στερεότυπα στους χώρους εργασίας. Χρησιμοποιώντας την κοινωνιολογική προσέγγιση/θεώρηση διαπραγματευόμαστε το φαινόμενο του κοινωνικού αποκλεισμού στο πλαίσιο της 4η Βιομηχανική Επανάσταση—που μόλις άρχισε— και ειδικά το τεκμηριωμένο ποσοτικά έμφυλο χάσμα (ανισότητες λόγω φύλου) που αυξάνετε ραγδαία. Η παρουσίαση αυτή επιχειρεί να συστηματοποιήσει σε μια κοινωνιολογική προοπτική τις δυναμικές που επέτρεψαν στην γυναικεία αντιπροσώπευση να καταστεί δείκτης της έμφυλης ανισότητας. Τo έμφυλο χάσμα αυξάνετε και στην κοινωνική περιοχή του αθλητισμού και συγκεκριμένα στην αθλητική ηγεσία, τη θεσμική εξουσία. Αναπαράγεται και με την μειωμένη κάλυψη του γυναικείου αθλητισμού στα ΜΜΕ καθώς και την μοντελοποίηση/ αντικειμενικοποίηση της αθλητικής ταυτότητας στα νέα μέσα και στα ΜΚΔ, ενισχύοντας τα φαινόμενα κατάχρησης εξουσίας (πχ. σεξουαλική παρενόχληση). Όπως τεκμηριώνεται ερευνητικά, στα πρόσφατα δημοσιευμένα στοιχεία του Παγκόσμιου Οικονομικού Φόρουμ, το έμφυλο χάσμα στην Υγεία και την Επιβίωση, την Παιδεία, την Εργασία, την Πολιτική, την Οικονομία, και την Τεχνητή Νοημοσύνη (ΑΙ) αυξάνεται παγκοσμίως, με την Ισλανδία να παραμένει η χώρα με τη μεγαλύτερη ισότητα των φύλων στον κόσμο. Προς ποια κατεύθυνση θα κινηθούν οι μεταβολές στο μέλλον; Εδώ προτείνουμε θεωρίες ή προσεγγίσεις περί έμφυλης ουδετερότητας, δηλαδή τη θέσπιση και την καλλιέργεια πολιτικών, στρατηγικών, (καλών) πρακτικών, μοντέλων, προτύπων (role models), μεντόρων, στάσεων και κοινωνικών συμπεριφορών που προωθούν την ισότιμη πρόσβαση, ένταξη, συμμετοχή και μεταχείριση στην εργασία, την επαγγελματική εξέλιξη, τη μισθολογική εξέλιξη, την ηγεσία, μεταξύ άλλων, άσχετα με το φύλο, την αναπηρία, την ηλικία, την κοινωνική τάξη, την εθνικότητα, τον σεξουαλικό προσανατολισμού ή την έμφυλη ταυτότητα. Στο ίδιο πνεύμα συντάχθηκε το Εθνικό Σχέδιο Δράσης για την Ισότητα των Φύλων (ΕΣΔΙΦ) 2021-2025. Όσον αφορά στην μελλοντική ζήτηση και την εξέλιξη της Τεχνολογίας στον αθλητισμό, και όχι μόνο, αναδύονται νέα ερωτήματα και συζητήσεις όπως: (1) Οι βιονικοί αθλητές/τριες του μέλλοντος θα γεφυρώσουν το έμφυλο χάσμα (έμφυλες ανισότητες), δηλαδή θα καταργήσουν την έμφυλη κατηγοριοποίηση (gender segregation) στον αγωνιστικό αθλητισμό; (2) Οι βιονικοί-υπεράνθρωποι αθλητές και αθλήτριες θα αποτελούν το μέλλον της ανθρωπότητας; (3) Η τεχνολογία θα κάνει τους αθλητές/τριες του αύριο πιο δυνατούς, πιο γρήγορους, πιο fit και πιο υγιής; (4) Πως η τεχνολογία, σε αθλητικές εκδηλώσεις, βελτιώνει την ακρίβεια, την απόλαυση και τις εμπειρίες όχι μόνο των αθλητών/τριών αλλά και των θεατών, καθώς και των θεατών με αναπηρίες. Συμπερασματικές παρατηρήσεις: Μολονότι η πανδημία του κορονοϊού (lockdowns, απολύσεις, κ.ά.) αποδυνάμωσαν την όποια πρόοδο προς την κατεύθυνση της ισότητα, προσθέτοντας 36 έτη στη γεφύρωση του έμφυλου χάσματος (in bridging the gender gap), στη σύγχρονη μετανεωτερική πραγματικότητα, το φύλο μεταβάλλεται από μια στατική αντίληψη σε μια δυναμική κοινωνική κατηγορία και ως εκ τούτου επηρεάζονται και μεταβάλλονται οι κοινωνικές προσδοκίες, οι έμφυλες σχέσεις, τα κοινωνικά στερεότυπα και οι κοινωνικές ταυτότητες.

Η παρούσα εισήγηση επικεντρώνεται στο επίκαιρο βιοηθικό θέμα της εφαρμογής της παρεμβατικής μεθόδου CRISPR/Cas9 στο ανθρώπινο γονιδίωμα, το οποίο απασχολεί έντονα τη βιοϊατρική και την χριστιανική ηθική. Η νέα μέθοδος επαγγέλλεται τη θεραπεία σε σημαντικές κληρονομικές ασθένειες και παθήσεις του ανθρώπου, ωστόσο εγείρονται σοβαρά βιοηθικά διλήμματα, τα οποία συνδέονται με τη γενετική επεξεργασία του ανθρώπινου γονιδιώματος (genome editing) και τον κίνδυνο της ευγονικής (eugenics). Η εφαρμογή της μεθόδου σχετίζεται με τα βασικά ανθρώπινα δικαιώματα της προστασίας, της αξιοπρέπειας και της ταυτότητας κάθε ανθρωπίνου όντος, την εγγύηση του σεβασμού της ακεραιότητας και των λοιπών δικαιωμάτων και θεμελιωδών ελευθεριών, αλλά και με την ισότιμη συμμετοχή στο κοινωνικό αγαθό της υγείας και της συνεπαγόμενης θεραπείας του ασθενούς.

Η Δημόσια Βιβλιοθήκη για τις Παραστατικές Τέχνες της Νέας Υόρκης διαθέτει σπάνιες αρχειακές συλλογές στον τομέα του Ελληνικού Θεάτρου, οι οποίες αφορούν το αρχαίο θέατρο και την πρόσληψή του, τη δραματουργία της Ελληνικής Διασποράς στις ΗΠΑ, τη θεατρική πρακτική των Ελλήνων μεταναστών και την πορεία των υπερατλαντικών θεατρικών περιοδειών. Πέρα από τα βιβλία, υπάρχει η τεράστια no-book συλλογή, η οποία περιλαμβάνει χειρόγραφα, προγράμματα, παρτιτούρες, σπάνιες ηχογραφήσεις, αποκόμματα, αποδελτιωμένες κριτικές, αφίσες, φωτογραφίες κ.α. Παρουσιάζονται τα σπουδαιότερα τεκμήρια, δίνοντας προτεραιότητα σε εκείνα που δεν είναι ψηφιοποιημένα.
Το άρθρο παρουσιάζει μέρος των πορισμάτων της ολοκληρωμένης έρευνας όπου εκπονήθηκε στο Τμήμα Θεατρικών Σπουδών του Πανεπιστημίου Αθηνών έπειτα από τη λήψη της υποτροφίας του Ι.Κ.Υ. για Μεταδιδακτορική Έρευνα στην Ελλάδα για το έτος 2009-2010. Παρουσιάζει την καλλιτεχνική πορεία ορισμένων Ελλήνων μεταναστών επαγγελματιών ηθοποιών οι οποίοι έδρασαν από το 1900 έως το 1922 σε εστίες του Ελληνισμού της Διασποράς. Το θέατρο αποτέλεσε ίσως τη σημαντικότερη καλλιτεχνική και κοινωνική έκφανση των εθνικών πνευματικών κέντρων όσο και των μεταναστευτικών κοινοτήτων του Ελληνισμού. Κάθε ελληνική κοινότητα του εξωτερικού διαμόρφωσε έναν «αυτόνομο» θεατρικό χαρακτήρα, αφού οι διαφορετικές κοινωνικές, πολιτικές και γεωγραφικές συνθήκες διαφοροποίησαν από τόπο σε τόπο τη γηγενή δραματουργία, το είδος των θιάσων καθώς και το ρεπερτόριο. Είναι παρακινδυνευμένο λοιπόν, να εξετάζεται το θέατρο της Διασποράς ως ένα ενιαίο θεατρικό είδος που εκτείνεται από τις ιστορικές παροικίες της Ανατολής έως τις μεταναστευτικές κοινότητες της Δύσης.

Publisher's VersionAbstract
Τα «θεατρικά παιχνίδια» (theatre ή drama games) είναι διαδικασία ή και μέθοδος εκπαίδευσης των ηθοποιών κατά τη διάρκεια της πρόβας, τρόπος φυσικής προθέρμανσης, μέσο ανάπτυξης αυτοσχεδιασμών, προεργασία δημιουργίας σκηνικών δράσεων στην πρωτογενή τους μορφή, αλλά και θεραπεία του άγχους πριν την παράσταση. Στη νεοελληνική θεατρική πρακτική τα «theatre games» συγκέντρωσης, προθέρμανσης, αυτοσχεδιασμού, αφήγησης, ρόλων, δυναμικής ομάδας κ.ά. ενθαρρύνουν τη δημιουργικότητα και αξιοποιούνται από τους Έλληνες σκηνοθέτες ωφελώντας τόσο τους ηθοποιούς όσο και την παράσταση, δηλαδή το κοινό κατ’ επέκταση. Το παρόν ερευνητικό άρθρο μελετά τη λειτουργία των theatre games στο σύγχρονο ελληνικό θέατρο με έμφαση στη διαδικασία της πρόβας. Το υπό εξέταση θέμα υπήρξε terra incognita για τη μελέτη της πρακτικής του ελληνικού θεάτρου. Συλλέχθηκε πρωτογενές υλικό με τη σύμπραξη είκοσι πέντε (25) Ελλήνων σκηνοθετών. Τα theatre games ενεργοποιούν όλους τους «νευροδιαβιβαστές της ευτυχίας» και συμβάλλουν θετικά στη διεξαγωγή της πρόβας, προσφέροντας τα εξής οφέλη: α) χαρά, β) εξάλειψη του άγχους, γ) ενεργοποίηση της φαντασίας, δ) ενδυνάμωση του σώματος, ε) σύνδεση της ομάδας, στ) προσαρμογή, ζ) επίτευξη στόχου, η) ενίσχυση συμμετοχής. Στη δομημένη ρουτίνα της επαγγελματικής πρόβας κανείς από τους ερωτηθέντες σκηνοθέτες δεν απέρριψε τα theatre games ως ανώριμη ή μη παραγωγική διαδικασία. Τα theatre games αλλά και οι σκηνοθέτες καλούνται συχνά να εμψυχώσουν ομάδες εκτός του πλαισίου των παραστατικών τεχνών, και τα applied theatre games λειτουργούν αποτελεσματικά σε επιχειρήσεις ως τρόπος ενδυνάμωσης σχέσεων, βελτίωσης δεξιοτήτων επικοινωνίας, απόκτησης ικανοτήτων επίλυσης προβλημάτων. Επίσης, πολλοί σκηνοθέτες χρησιμοποιούν τα theatre games και στη διδασκαλία της υποκριτικής. Τέλος, αναφέρονται οι επιρροές των σκηνοθετών και οι διαδικασίες επινόησης - μετεξέλιξης νέων theatre games.
In this paper we investigate a specific case of face verification: Given some confirmed photos and video frames of Leonidas Arniotis, a Greek artist of late 1800’ and early 1900’s, we have examined two photos, of very low resolution, of an unknown person that could be Leonidas Arniotis. The widespread of deep learning and the availability of ResNet50 model, which was trained on VGGFace2 dataset, allowed us to apply transfer learning for face verification purposes. At the same time an alternative technique which is based on facial points matching was applied. The main aim of the paper is to show that despite the progress made in the fields of face recognition and face verification, actual systems that can be used by non-experts for examining real world cases, like the one we deal in the current paper, remain impractical. In the framework of the current work, we also examine and discuss, in a critical way, the effectiveness of transfer learning for real face verification cases through specific examples.
Το επικαιροποιημένο Εθνικό Σχέδιο Δράσης για την Ισότητα των Φύλων (ΕΣΔΙΦ) 2016-2020 (1) συμπεριλαμβάνει τον Αθλητισμό ως εργαλείο ενσωμάτωσης και κοινωνικής δικαιοσύνης. Οι στρατηγικοί στόχοι που τέθηκαν περιλαμβάνουν την «προώθηση της ισότητας στην εκπαίδευση, τον πολιτισμό, τα μέσα ενημέρωσης και τον αθλητισμό». Το ΕΣΔΙΦ θέτει έξι στρατηγικούς στόχους με σκοπό να ενισχυθεί η διάσταση του φύλου στους κοινωνικούς, πολιτικούς, εκπαιδευτικούς και αθλητικούς φορείς, με την εφαρμογή ειδικών μέτρων για την πρόληψη και εξάλειψη των έμφυλων ανισοτήτων. Ερευνητικά δεδομένα δείχνουν ότι η συμμετοχή των γυναικών στην αθλητική δραστηριότητα μπορεί να οδηγήσει σε αμφισβήτηση/αναθεώρηση των περί φύλου κοινωνικών στερεότυπων (2). Σκοπός της παρούσης μελέτης είναι, να διευκρινιστεί κατά πόσο υλοποιήθηκε ο στόχος του ΕΣΔΙΦ, που αφορά στην ισότιμη μεταχείριση των γυναικών στα Ανώτατα Στρατιωτικά Εκπαιδευτικά Ιδρύματα (Α.Σ.Ε.Ι), δίνοντας ιδιαίτερη βαρύτητα στην αθλητική-στρατιωτική εκπαίδευση των σπουδαστών και των σπουδαστριών. Επιλέχθηκαν και αναλύθηκαν οι οδηγοί σπουδών των πέντε Ανώτατων Στρατιωτικών Εκπαιδευτικών Ιδρυμάτων (Στρατιωτική Σχολή Ευελπίδων, Σχολή Ναυτικών Δοκίμων, Σχολή Ικάρων, Σχολή Αξιωματικών Νοσηλευτικής, Σχολή Αξιωματικών Σωμάτων), με έμφαση στα αθλητικά-στρατιωτικά προγράμματα. Αναλύθηκαν και οι συνεντεύξεις δώδεκα εν ενεργεία γυναικών αξιωματικών. Τα αποτελέσματα της έρευνας έδειξαν ότι και στα πέντε Α.Σ.Ε.Ι.: τα αθλητικά στρατιωτικά προγράμματα είναι ισόνομα, χωρίς έμφυλες διακρίσεις (στηριζόμενα και στη δράση του ΕΣΔΙΦ), όπως επιβεβαιώθηκαν και από τις συνεντεύξεις των 12 εν ενεργεία γυναικών αξιωματικών (Σχήμα 1, 2 και 3). ΣΥΜΠΕΡΑΣΜΑΤΑ: 1) Προωθείται το ομαδικό έργο (η ομαδικότητα, η συνεργασία, η συνοχή, η αποδοχή), 2) Διευκολύνεται η αλλαγή των έμφυλων στερεότυπων, 3) Καλλιεργούνται οι κοινωνικές σχέσεις, 4) Προωθείται η ενσωμάτωση του φύλου (έμφυλη ισότητα), και ειδικά η γυναικεία ενσωμάτωση, διατηρώντας την ιεραρχία μέσα στην ομάδα.-----------------------------------------------------------ΛΕΞΕΙΣ ΚΛΕΙΔΙΑ: Φύλο, γυναίκα, στρατός, Ανώτατα Στρατιωτικά Εκπαιδευτικά Ιδρύματα (Α.Σ.Ε.Ι), έμφυλη ισότητα, γυναικεία ενσωμάτωση, αθλητικά προγράμματα
Σε παγκόσμιο επίπεδο, ένας σημαντικός αριθμός ερευνών έχει δείξει ότι οι έφηβες συμμετέχουν σε σημαντικά λιγότερη φυσική δραστηριότητα σε σχέση με τους έφηβους. Παράλληλα, έχει τεκμηριωθεί η μικρότερη συμμετοχή των έφηβων μαθητριών στο μάθημα της Φυσικής Αγωγής σε σχέση με τους έφηβους μαθητές (1) και η μείωση αυτή παρατηρείται ήδη με την έναρξη της εφηβείας. Σκοπός της παρούσας εργασίας είναι να εντοπίσει και να αναδείξει τους παράγοντες εκείνους που περιορίζουν ή ακόμη και αναστέλλουν καθώς επίσης, και τους παράγοντες που διευκολύνουν τη συμμετοχή των μαθητριών Γυμνασίου και Λυκείου στο μάθημα της Φυσικής Αγωγής και στην άσκηση/φυσική δραστηριότητα. Μέθοδος: Για την παρούσα βιβλιογραφική ανασκόπηση αναζητήθηκε αγγλόφωνη και ελληνόφωνη βιβλιογραφία (μετά το 2004) μέσα από τις μηχανές αναζήτησης Google Scholar, Pubmed, Research Gate & Science Direct, καθώς και από τις βιβλιογραφικές αναφορές δημοσιευμένων εργασιών. Επιλέχθηκαν οι 16 πιο πρόσφατες έρευνες που πληρούσαν τα κριτήρια αναζήτησης και στις οποίες υπήρχε πρόσβαση μέσω ΕΚΠΑ. Αποτελέσματα: Οι παράγοντες που περιορίζουν ή αναστέλλουν τη συμμετοχή των έφηβων κοριτσιών μπορεί να είναι ατομικοί (μεταβολή προτεραιοτήτων, έλλειψη δεξιοτήτων, ανταγωνιστικό κλίμα, εικόνα σώματος), κοινωνικοί [οικογένεια, φίλοι, συνομήλικοι/επικρατούσες αντιλήψεις περί φύλου (2)] ή περιβαλλοντικοί (είδος δραστηριοτήτων, αθλητικές εγκαταστάσεις, εκπαιδευτική πολιτική). Ως υποστηρικτικοί παράγοντες θεωρούνται (μεταξύ άλλων) η ποικιλία δραστηριοτήτων, η άσκηση με φίλους και η απουσία ανταγωνισμού.
Συζήτηση/Συμπεράσματα: Καθίσταται επιτακτική η ανάγκη προώθησης ενός θετικού και συμπεριληπτικού περιβάλλοντος για την άσκηση και τη φυσική δραστηριότητα των έφηβων κοριτσιών, εντός και εκτός σχολείου. Με αυτό τον τρόπο βελτιώνεται η υγεία και η ποιότητα ζωής των κοριτσιών και, παράλληλα, ενισχύεται η προοπτική της δια βίου άσκησης.

Geological failures from massive rockfall failures to small landslides of few cubic meters are a major geological hazard in many parts of the world. Based on the latest developments, close-range photogrammetry and individually UAV photogrammetry and Light Detection and Ranging systems have become indispensable tools for geo-experts in order to provide ultra high-resolution 3D models of the failure site. TLS suffers from the fact that is sometimes tricky to capture the holistic area of interest from the ground, while some areas may often be obscured by vegetation or negative inclinations. The science of photogrammetry has long been used to accurately detect and characterize landslide and rockfall failures. Due to the continuously increasing spatial resolution capability of new generation sensors, traditional pixel-based approaches are not capable to cope with the level of detail resulted from those sensors. Mostly, landslides present complex and dynamic geomorphological features with great heterogeneity in their spatial, spectral and contextual properties dependent on the specific failure mechanism. In the current study, an object-based 3D approach for the automated detection of landslide and rockfall hazard is presented based on detailed topographic photogrammetric point clouds and 3D analysis. Recent trends show that close photogrammetry will play a vital role on the geological and engineering geological assessments concerning geo-failures. The results show that object-based approach is closer to human interception due to integration of contextual and semantic, spectral and spatial information rather than translating pixel’s spectral information solely. The current procedure provides a detailed objective quantification of landslide characteristics and automated semantic landslide modelling of the case site.

The purpose of this research is to combine two state-of-the-art technologies in surveying for extracting the rock thickness above a cavity. By combining Lidar technology for indoor surveying and photogrammetric processing of Unmanned Aerial Systems (UAS – drones) data, we managed to calculate and project with high accuracy the rock thickness of the roof of the underground environment of Koutouki Cave (Peania, Greece).
Usually, cave systems are complex and unique because of their distinctive geometry and compound geomorphology along with natural harsh conditions such as constrained accessibility, limited light, high humidity and possible existence of water. Such environments make mapping difficult and further complicated (Kershaw, 2012). Nowadays, the state-of-the-art in surveying of open surface is based on LiDAR technology. Lately, similar technology has started to be used for indoor surveying and consequently in cave mapping, especially where the underground space allows it.
Our research was based on the use of a recently released piece of equipment introducing a lightweight mobile handheld laser scanning system (GeoSLAM ZEB – REVO) that has the ability to produce a quite dense point cloud within an underground cavity. The x, y, z point cloud is generated while the operator walks through the cave (Zlot and Bosse, 2014). The specifications of this equipment include a 360o rotation, a (class 1 eye safe) 100Hz laser – making 100 rotations per second with the collection of 43,200 points per second. The maximum effective range is around 25-30m for indoor environment and data over 30m are usually excluded.
Two well-developed quaternary sand dune fields have been identified on the western and eastern side of Akrotiri promontory (Lemesos, Cyprus). The fields extend immediately from the low level of their source beaches onto higher ground (> 38m amsl). Geomorphic observation supported by OSL dating of multimineral sand horizons demonstrate several phases of sand accumulation in the western field in contrast to the smaller eastern system, where the evidence direct to a relatively recent dune emplacement. The effects of climatic change, relative sea-level change and anthropogenic influence in dune evolution, have been evaluated in both sites in combination with documented evidence of human induced destabilization of the western sand dune field during the 1970s and 1980s. Both fields share similar topographic settings and situated in close proximity but they do not share an entirely similar evolution history. The οbservations and the data suggest the combination of local and regional control of the development of the sand dunes and the geochronological analysis with
luminescence methodology support the ability of the method to reconstruct the evolution of sand dunes fields in the eastern Mediterranean area.
The quantification of the amount of the expected eroded material that will migrate towards lower elevations after a forest fire is one of the most crucial and practical information needed from the local authorities, in order to design post-fire stabilization measures and actions. It is one of the greatest challenges in natural resources and environmental planning and computer simulation models are becoming increasingly popular in predicting soil loss for various land use and management practices. Quite a few models along with their modifications are being developed aiming to fulfil the need for accurate quantification of soil erosion risk. Depending on the availability and the quality of the spatial data, which have to be imported into the various models as parameters, different methodologies are followed. Geraneia Mt is an extended mountain range at the west outskirts of Attica, central Greece, reaching the altitude of 1351 m, part of which has been designated as Natura 2000 site and is characterized by almost vertical slopes of carbonate rocks. The mountain was almost completely burned by a wild fire in late July 2018, which consumed most of its Pinus halepensis forests. The ridge of the protected area, covered by endemic fir Abies cephalonica forest was also affected by the fire. The soil covers carbonate rocks which comprise the higher elevations and the vertical slopes of the mountain as debris and loose deposits crop out at the south-facing mountain front which was greatly affected by the fire. Several erosion risk spatial models were applied on the protected area of Geraneia Mt in order to compare the sensitivity of their results and evaluate the risk of the affected habitat to be deteriorated. For each model, the most sensitive model parameters were calibrated and predicted soil loss amounts were compared. A qualitative and quantitative estimation was achieved and the advantages and disadvantages of each model had been identified.
Akrotiri Penisnsula is located west of Limassol at the Southern end of the Island of Cyprus. It covers an area of approximately 100km². The development of the peninsula started with the deposition of calcareous marls in to the Episkopi grabben during the Miocene which resulted the Akrotiri High in the form of an isolated island. The maritime space between the Akrotiri Island and the mainland eventually closed during the Quaternary and several geomorphic features were developed. Beachrocks identified at three continuous pocket beaches at the southwest part of the Akrotiri
peninsula. Detailed GNSS measurements and GIS analysis revealed that the area is uplifted. A direct relationship between the development of the beachrocks and the paleogeographic evolution of the area is apparent. Additionally, results from Petrographic, mineral and sedimentary analysis on beachrock samples are indicating a continuous supply of material from the nearby Kouris River. A gradual reduction of the sediment granulometry consists the beachrock is observed. Also the
transition of the texture of the samples from non-uniform to uniform is observed. The sample mineralogy varies eg quartz, alkaline feldspars, carbonate minerals, ortho and clino pyroxenes, serpentinites, hornblende, muscovite. A reduction in the contribution of overbearing minerals (according to their hardness) was observed from North to Southern beachrock slabs and the increase of carbonates, quartz and feldspart. It should be noted that there is a strong participation of fossils fragments were a number of them was preserved in good condition. SEM-EDX analysis were conducted and showed that the micritic and sparitic crystals of cement are consisted by High Magnesium Calcite +(>4 mol% CaCO3 or 1.2 wt.). The cement agent forms an isopachous coating around the sediment grains and with meniscus forms connect all the sedimentary particles which leads to the formation of a high density beachrock slabs.
Beachrocks are hard coastal sedimentary formations consisted from various beach sediments, coastal fauna residues and anthropogenic articles. Beachrocks are rapidly cemented through precipitation of carbonate cements typically consisted of High-Magnesian Calcite (HMC), which commonly precipitates in shallow marine environments, (>4 mol % CaCO3 or 1.2 wt. %) or aragonite (Ar). However, debate still exists concerning the accurate depositional environment of beachrocks and data for the mechanism of their formation are considered necessary. This study aims to contribute to the understanding of the beachrock
formation, using mineralogical and geochemical methods, analyzing the cement and the consolidated sediments. Bulk samples were collected from three consecutive beaches located at the West part of Akrotiri Peninsula (Cyprus island). The samples were examined
under polarizing microscope for the determination of the cement (HMC as micritic and sparitic crystals), its characteristics (isopachous bladed coating, formation of meniscus etc) and the participation of well-preserved fossil fragments. The mineralogical analysis, with the use of XRD analyzer, indicated a variety of minerals which consisting the beachrock (quartz, carbonates, plagioclase, olivine, biotite, zircon etc). Using SEM-EDS it was possible to accurately determine the cement composition and to observe its crystal characteristics. The cement agent was mainly consisted by High-Magnesian Calcite (HMC) of different crystal
sizes and matrix material was present as secondary pores filling. The three studied beachrocks at the west of Akrotiri peninsula, were formed in the middle-low intertidal zone. Evidence of continuous uplift of the beachrock is observed both from geomorphological
analysis and through its infrastructure. The beachrocks were highly affected by the nearby Kouris river, which supplied the material derived from the inner Cyprus areas rich in Mg2+ rocks (eg. ophiolites) and Ca2+ (eg. limestones, marbles).
Cyprus has a long record of tsunami waves, as noted by archaeological and geological records. Large boulder deposits have been noted in southeastern and western part of the Island. In the area of Cape Greco (southeastern Cyprus) large boulders have been noted, however, no detailed geomorphological research exists so far and the related high energy event remains undated. In this context, we focused at Cape Greco Peninsula at the southeastern coast of Cyprus, in order to record in detail large boulders deposits. The accumulation of the boulders along the uplifted coastline (3m amsl) was recorded. The
boulders are fragments of a layer of an upper Pleistocene aeolianite, which is overlaying unconformly a lower Pleistocene calcarenite. Dimensions and spatial distribution of 272 small, medium and large boulders were documented. The precise distance of the boulders deposition from the coastline was recorded by field measurements and remote sensing with the use of GNSS, Drone mapping and GIS technics. Several large boulders weighting more than ~30 metric tons were located up to 60m inland. Geomorphologic mapping and morphometric measurements, along with the presence of marine organisms suggests that some of the boulders were removed from their original intertidal zone and were transported inland by the force of large waves. Samples of Vermetus sp. were collected from the displaced boulders in order to date the extreme event. In this work, we report and compare preliminary results from the application of widely accepted hydrodynamic equations, in order to determine the extreme event that caused their transport inland. We further attempt a correlation of the event with already known tsunami events from Eastern Mediterranean, based on the estimated wave heights and the radiocarbon dating of marine gastropods (Vermetus sp.).
Late years, innovative close-range Remote Sensing (RS) technology such as Unmanned Aerial Vehicle (UAV) photogrammetry and Terrestrial Laser Scanning (TLS) are widely applied in the field of geoscience due to their efficiency in collecting surface data. Detection and mapping of landslide and rockfall events using RS products has been proved to be an effective approach to provide landslide inventories. However, most of the studies are lacking valuable semantic information about landslide elements and how they react with the surrounding environment. The proposed methodology was divided in five main working phases. The first phase includes designing and execution of an optimal UAV flight planning to collect accurate 3D data. During the second phase, the pre-processing and raw data preparation such as point cloud filtering and elimination of ambiguities is taking place, while at the next phase an image segmentation using the 3D point cloud RGB information is created. The main task was focused on identifying the specific landslide elements by using an object-based approach. A sequence of image-based processes was applied, including multi-scale object segmentation, spectral, morphometric and contextual information extraction aiming to detect the landslide among other features. The next phase was set up for object classification in meaningful and homogeneous landslide classes (e.g. scarp, depletion zone, accumulation zone) which are spatially connected by introducing contextual information. The proposed methodology presents the effectiveness and efficiency of UAV platforms to acquire accurate data from intense relief environments and complex surface topographies.
In order to study the geomorphological and environmental characteristics of St. George bay, western Naxos, Greece (Fig.1), a series of 14 beachrock samples were collected and examined. Two transections of the bay, based on field measurements, were designed, in order to provide a deeper understanding of the beachrock development setting. Detailed recording of the beachrocks was accomplished through scuba diving, using a sonar device, measuring tapes, GPS device and Dive Computer. Special attention was given to the cement, as to extract information about the conditions of formation of the beachrocks. Thin sections from the beachrock samples were studied through petrographic microscope in order to investigate their basic characteristics and to obtain information about their basic petrographic and mineral composition. Scanning Electron Microscopy (SEM) alongside with Energy Dispersive Spetrometry (EDS) were used for elemental analysis of the beachrock samples and their cement and Raman spectroscopy was used for identification of the cement crystal structure. For better interpretation of the results, the suggested tool, by Mauz et al. (2015), for reconstructing relative sea level in the far-field was used. In order to estimate the ecological status of the bay, a study of the macroalgae of the area was also accomplished. Macroalgae sampling of two different methods was conducted, destructive (conventional samples) and non-destructive (photographic samples). 57 conventional samples were collected throughout the beachrock reef. These samples were prepared into herbariums and were identified in the best taxonomic level possible using stereoscope and microscope. Photographic samples were taken from the southwestern and northeastern part of St. George bay, from different types of bedrock (beachrocks, granodiorite, aeolianite) for comparison reasons. The percentages of different types of surface coverage (algal, sediment coverage) were counted for each sample, using the program Adobe Photoshop CS6. Finally, a statistical analysis of the data from the photographic samples was conducted, using the program PRIMER 5, in order to have a better evaluation of the algae data. The depth and coordinates of each conventional and photographic sample were recorded.
The results regarding the beach rock samples indicate that their formation took place under meteoric and marine vadose zone conditions. Certain results indicate that the development of the beachrocks took place during a sea level rise. Finally, macroalgae statistical analyses indicated that there are no significant differences between beachrocks and other rocks as substrates and the overall ecological status of St. George bay can be characterized as good, according to the Ecological Evaluation Index (EEI, Orfanidis et al., 2003).
The use of techniques of two different origin were compared and combined aiming to map the seagrass meadows at shallow waters of South Evoikos Gulf, in central Greece. The high spatial and spectral resolution of WorldView-2 satellite images and its ability of water penetration, offers a positive approach for sea bottom mapping, in a relatively high resolution. In addition, the ground truth fieldwork survey with side scan data acquisition revealed that it was in impressively high agreement with the outcomes from the remote sensing data interpretation.
The use of Very High Resolution (VHR) satellite imagery at various applications is gaining more and more popularity due to the growing number of offered data and the increasing spectral properties. WorldView-2 is the first commercial VHR multi-spectral satellite providing imagery in eight different sensors having bands that range from the visible to near-infrared (0.40-1.04 μm). The integration of the “Coastal” band (0.40-0.45 μm) in the 8-band WorldView series of satellite imagery data, which was followed by the addition of the similar wavelength band 1 (0.43 - 0.45 µm) in the Landsat-8 Operational Land Imager (OLI), gave a great boost to applications related to shallow water depths. The fundamental principle underlying the methods used to study the sea bottom from remotely sensed imagery is that different wavelengths of the solar light penetrate the water body to different depths (Phinn et al. 2008).
The ability to accurately determine the seagrass at underwater regions is of great importance for the biodiversity of the submarine environment. The use of certain spectral wavelength data tends to be the most cost effective way of monitoring the marine habitats by mapping the sea bottom type along with several other jobs like modeling coastlines or even navigating through shallow aquatic areas by studying the bathymetry (Fornes et al. 2006).
Beachrocks are a window in the past environmental, geological, sedimentological and geographical conditions that were dominant on the coastal zone. The minerochemical examination of cement and the sedimentological analysis are the most efficient methods for understanding the formation mechanism. However, the examination of beachrock samples have limitations and the evidence of formation mechanism are not enough. This study emphasizes on the beachrock formation mechanism through the comparison of cement characteristics, mineral chemistry and sedimentology of beachrock occurrences from different geological and geographical setting areas Diolkos, Corinth, Greece and Sumuide, Okinawa, Japan. Furthermore, in order to investigate the beachrock formation, artificial beachrock samples were created in-vitro using sand samples and ureolytic bacteria from Okinawa under accelerating conditions. Bulk samples were collected from the study areas in order to analyze their mineralogical (XRD and SEM-EDS) and chemical (XRF) composition. Microscopy studies (optical and SEM-EDS) revealed that the cement agent from Diolkos is mainly composed of High-Magnesian Calcite (HMC) in comparison to the Sumuide beachrock which is characterized by the presence of calcite and aragonite. Additionally, the analysis revealed clastic silicate and aluminosilicate minerals. The grain composition of Diolkos slab consists of
quartz, plagioclase, K-feldspar with 20% bioclasts compared to the Sumuide beachrock grains that consist of calcareous residuals from the local coral reef. The artificial beachrock investigation indicated that ureolytic bacteria that reside in the Sumuide beach sediment, are capable to precipitate aragonite coating the sediment grains and filing the pores. The cementation was most active in the top part of the samples than the bottom part. This is an indicator that the beachrock formation might occur in depths were these bacteria can be found. The artificial beachrock analysis included its physicochemical parameters using UCS
penetration, pH and Ca2+ measurements, X-Ray CT-scanning, petro-graphic polarized microscopy, XRD, and SEM-EDS.
Sedimentological and geomorphological features of Mylopotas and Manganari beaches in Ios Island are investigated in order to determine seasonal changes in the texture of coastal sediments and shoreline position caused by both natural processes and human activities. The fieldwork was conducted in April 2018 and September 2018 including mapping of beach morphology in seasonal scale through topographic monitoring of shoreline, coastline and fixed cross sections in the sites under investigation using a differential GPS. In addition, sediment sampling was carried out along selected cross sections in beaches of Mylopotas (three) and Manganari (two). Grain size analysis and statistical processing were realized to reveal spatial and temporal changes of sediment parameters, such as sorting, skewness, mean and kurtosis. The results indicate a rather homogenous grain size distribution at each study area, with the majority of samples being classified as slightly gravelly sand. DGPS
measurements of shoreline position in Manganari Beach indicate changes that vary between 2.50 m and 4.70 m, with the maximum displacement to be observed in the southern part of the beach, where the shoreline is retreated during spring period. Seasonal variations of shoreline position in Mylopotas Beach are up to 4.50 m with the shoreline to be advanced during spring period in the southern and northern part of the beach, while the minimum changes are measured in the central part, where a beachrock formation occurs. Occasional human interferences, such as small-scale beach restoration and nourishment projects, installation of leisure facilities and reshaping of sand dunes, conducted mainly during spring period, alter the coastal sediment budget and transport reinforcing shoreline retreat.
The Ingessana hills in the southern Blue Nile of Sudan consist of serpentinised and highly silicified dunites in contact with the intruding Bau granite. The observed chromite mineralization zones are associated with NE-SW trending shear-zones. The mineralization associated with ophiolitic belts includes podiform chromite, asbestos, talc, and base metal (Cu, Ni, Co) mineralization. We applied Linear Spectral Unmixing algorithm on a 10m spatial resolution Sentinel-2 images in order to detect and map the chromite mineralization and the associated mineralization of ophiolitic belts. The resulting abundance maps show the capability of Sentinel-2 for detailed mineral mapping and detection of potential chromite ore deposit locations.
The study of the east dipping N-S mountain front of Olympus Mt that is presented in this work, was based on the interpretation of high-resolution digital elevation model (DEM), as the main dataset for calculating various tectonic geomorphology indices, through quantitative techniques. Since the fluvial network maintains its connection to the tectonic forcing and therefore contains potentially useful information about variations in rock uplift rates across the landscape, we used a highly detailed one generated from the DEM in order to calculate various indices and extract quantitate information. Calculations were made in a GIS platform by using the Ks index, the drainage basin asymmetry index and the geometry of the triangular facets on the front of the mountain, alongside the fault zone delineating the mountain. The results extracted by combining the previous methodologies are in agreement with the observations which were made during the fieldwork, that there is no uniform uplift along the main Olympus fault zone.
Developing educational material based on satellite remote sensing technologies, information and methods, is a key trend in modern pedagogy of Earth System Sciences. Here, we present “MICE”, a classroom activity on Melting ICe Effects, that utilizes remote sensing information to demonstrate the value of Earth Observation (EO) as a context to teach the STEM (Science, Technology, Engineering and Mathematics) school curriculum. The activity focuses on the subject of polar ice melting as a main climate change effect and the different impact of land and sea ice melting on sea level rise. Students, have the opportunity to discover the above experimentally and subsequently, to observe the diachronic change on polar ice through sequences of satellite images and discover the positive climate feedback on global warming. The activity was translated and adapted to the Greek curriculum from the freely available classroom resources of the European Space Agency (ESA, “Teach with Space” collection). MICE, has been enriched with Greek scientific material, including up-to-date information on climate impacts, localized for the extended region. As part of an evolutionary process, the activity was pilot-tested with 6th grade primary school students and adjusted according to the trial findings. This work is considered as the first step towards the development of original Greek educational material that will utilize EO and climate change as the context to teach STEM school curriculum, capitalizing on the pedagogical role satellite remote sensing and inquiry-based teaching methods, can play.

The synergy of different methods was used for the creation of an earthquake-induced landslides (EIL) inventory for the Ionian Islands. More specifically, post-earthquake field surveys were conducted shortly after recent earthquakes (2003 and 2015 in Lefkada, 2014 in Cephalonia and 2018 in Zakynthos) in order to obtain detailed field information of the EIL among other earthquake effects. The available literature on historical earthquakes were reexamined with emphasis on their environmental effects and especially EIL. Remote sensing products including satellite imagery and orthophotos were interpreted. All qualitative and quantitative information related to EIL and derived from the aforementioned steps were inserted in a database especially designed and developed in GIS environment for the purpose of this study and the respective inventory map was produced. This landslide inventory map was used and combined with other thematic maps in order to test the earthquake-induced landslide susceptibility (LS) of the Ionian Islands. The Analytical Hierarchical Process was applied along with the Weighted Linear Combination method in the frame of a multi-criteria decision analysis for the calculation of the spatial distribution of the Landslide Susceptibility Index (LSI). Along with the inventory, morphological data were derived from a TanDEM-X elevation model of the Ionian Islands based on data produced by TanDEM-X and TerraSAR-X satellite pair. Lithological and geological data were digitized from previous already published geological and neotectonic maps updated with corrections from field mapping for the purpose of this study. Land use and soil thickness were derived from the 2018 version of Corine Land Cover. Road network was digitized from the topographic maps of the Hellenic Military Geographical Service, while rainfall data was collected from the database of the National Meteorological Service. Data classification of each factor according to their estimated LS followed, by using the reverse ranking method, where 1 is the least and 10 is the most susceptible. Each category was normalized to 100% and the final raster thematic maps of landslide controlling factors were produced. Finally, using numerical weight for each factor, which was assigned by the Analytic Hierarchy Process using Pairwise Comparison Method and according to the weighted linear combination, a map was generated where each cell has a certain LSI value. The higher the LSI value, the higher the LS, whereas lower LSI value means lower LS. The resulted map, classified with natural breaks method, constitutes the earthquake-induced LS map of the Ionian Islands with five LS categories: very low, low, moderate, high and very high LS. Comparison of the EIL inventory map and the LS map show that the EIL in the Ionian Islands are structurally controlled as the majority of them have been generated along morphological discontinuities formed by active faults or inactive thrusts and overthrusts.
The spatial and temporal scale of flash flood occurrence provides limited opportunities for measurements and observations using of conventional monitoring networks. These observational difficulties, often accompanied by a lack of instrumental data have turned the focus to event-based, post-disaster studies. Post-flood surveys are particularly useful, as they provide the opportunity to observe aspects of hydrological behaviour of catchments under rare runoff conditions and extreme meteorological forcing, by capitalizing on field evidence. Recently, unmanned aerial vehicles (UAVs) and the Structure for Motion (SfM) technique have been used to enhance field surveys and monitoring related to different aspects of disasters. The simple consumer-grade equipment required, its enhanced observation capabilities and certain conveniences they offer in field surveys indicate a strong potential of these technologies in many aspects of flash floods, especially given the opportunistic nature of their study. This work explores further this potential, aiming to demonstrate the application of UAVs in post-flood peak flow estimation. The research team surveyed two selected cross sections after the catastrophic 2017 flood of Mandra, developing a high resolution (2.7cm) digital surface model (DSM) using UAV imagery and the Structure from Motion technique (SfM). The detailed DSM was used to study channel geometry and flow obstructions, extract cross sections and calculate the cross sectional area and wetted perimeter. Water energy slope was defined with the use of high water marks that were placed on the DSM on the appropriate elevation. Peak discharge in the two ungauged sections were estimated at 170m3/s and 140m3/s (with a range to account for the uncertainty inherent in the dynamic nature of Manning coefficient), using the slope-conveyance method, indicating a unit peak discharge of approximately 9-10m3/s/km2. Following recommendations described in relevant literature on the integration of survey observations by means of hydrological modelling, we applied a spatially distributed hydrologic model to simulate discharge at the surveyed cross-sections (the Kinematic Local Excess Model (KLEM)) and other checks, all of which were in agreement, with the peak flow estimates provided by the UAV-aided survey analysis. The UAV allowed the collection of aerial imagery in a rapid way from an extensive area, despite that a large portion of it was inaccessible due to road closures and safety issues. In addition, detailed DSMs created using aerial imagery and the SfM technique was found to be particularly useful for studying channel geometry, obstructions and other characteristics of flow as well as for measuring cross sectional areas on demand, even at a later time, when the channel had changed due to human intervention (e.g. cleanup using heavy machinery) and water flow. These capabilities fit to the opportunistic context of studying flash flood events in the sense that UAVs can rapidly collect information within the short time frame that it is available. Nevertheless, it has to be noted that combination of ground with aerial observations is preferable.
The purpose of the study is the determination of the shoreline changes and the sediment processes along the beach of Marathon Bay, which is located at northeast Attica. In the wider on shore area the Schinias National Park, at the northeast of the bay, the Olympic Rowing Centre, military bases, archeological sites, museums etc. are encountered. The area is also characterized by high touristic activity during summer. In the area there are specific locations and constructions endangered due to coastal retreat. A lagoon was established in the study area 3.500 years BP (Pavlopoulos et al., 2006) as it is characterized by low elevations, gentle slopes and fine sediments. A survey of the coastal and marine geomorphology was carried out by acoustic scanning of the seafloor with an echo sounder and sonar side scan topographical sections perpendicular to the shoreline along with collection and analysis of surface sediments. The quantification of long-term shoreline displacements was carried out by comparing historical and contemporary aerial photographs (1945, 1960, 1969, 1988, 1996, 2001, 2010) along with very high resolution satellite imagery (2012, 2014, 2015, 2016, 2017, 2018), not to mention the tracing of the coastline (2013) with Real Time Kinematics equipment (RTK-GNSS). The quantification of long-term shoreline displacements was made with the use of the add-on application of Digital Shoreline Analysis System (DSAS) within the GIS platform ArcMap 10.6 (Thieler et al., 2009). This was accomplished by drawing 261 transects (every 50 meters), except those neighboring anthropogenic structures, perpendicularly to the historical shorelines from a stable baseline (Tsokos et al., 2018). At each transect the rate of displacement was measured.
Floods are among the most dangerous natural hazards affecting the development of an area. In Greece, many drainage basins are relatively small with steep slopes, configured by steep streams with braided main channel morphology. These systems are usually dry, but experience extreme flash flood events of low frequency, but high magnitude. Such exceptionally high runoff may be a source of significant damage to human infrastructure. Despite the importance of these floods, the hydrological analysis of ephemeral streams in Greece has been especially difficult due to the lack of discharge gauges.The aim of this study is to present a flood hazard assessment and mapping methodology for the Kerinitis River drainage basin which is located in the North Peloponnese. Additionally, the simulation of a flash flood event along the main channel of the river caused by an extreme rainfall event, similar to the storm that took place on January 11th and 12th, 1997 above the nearby catchment of Xerias River, using a surface GIS-based runoff model was attempted. The application of this modeling led to the direct runoff hydrograph along the Kerinitis main channel at the outlet of the basin (the apex of the fan-delta). The proposed methodologies are based on the application of GIS with the integration of various data concerning the study area.
Curt C, Kamberidou I. GENDER, ENTREPRENEURSHIP, SPORT AND PHYSICAL ACTIVITY IN FRANCE. 5th Scientific Conference on "Physical Activity and Health". School of Physical Education & Sport Science, National and Kapodistrian University of Athens, 12-14 April, Athens, Greece. 2019.Abstract
Physical activity, health and well-being are valued in France, where over 65% of the population practice sport (Schann, 2014). French towns provide sport clubs, athletic facilities and parks for jogging, running or cycling and most workplaces include gyms, fitness programs or sport activities. Companies like Apple have integrated gyms in the workplace; the bank Société Générale provides dance activities for employees and managers; the Valeo group-smart technology for smart cars organizes sport events resembling the Olympics. Physical activities are encouraged to improve or maintain employee health while developing-strengthening cooperation and teambuilding for both genders. In contrast, gender inequality prevails, especially in sport leadership and entrepreneurship. This study focuses on the major obstacles confronted by women entrepreneurs in France and in francophone countries.
Method: In depth literature review (30 studies) on women’s entrepreneurial activities over the period 2002-2018, a topic not sufficiently studied in France, including two studies on gender inequalities in sport.
Results: The leaky pipeline, a barrier to retention, along with the family/work conflict, lack of trust, funding or access to capital and limited-inadequate networking.
Discussion/Conclusion:
Need to eliminate gender stereotypes in France. Out of the 30 million people over 18 years of age who play sport or engage in physical activities at least once a week, almost half are women (14.5 million). On the other hand, women continue to be invisible (underrepresented) in sport leadership and entrepreneurship. They usually turn to social entrepreneurship: education, social care or health services. Future studies required to identity obstacles confronted by women entrepreneurs in France, the country of the first woman Olympic entrepreneur, Alice Milliat, who was compared to Pierre de Coubertin in 1922 for the successful organization of the "Women’s Olympic Games" in Paris on August 20, 1922, an event which attracted 20,000 spectators (Kamberidou, 2016).
Akrotiri Salt Lake is located 5km west of the city of Lemesos, in the southern-most part of the island of Cyprus. The palaeogeographic evolution of the Akrotiri Salt Lake presents a great scientific interest, especially during the Holocene where the eustatic movements combined with local active tectonics and climate changes have developed a unique geomorphological environment. The Salt Lake, today a closed lagoon, which is depicted in Venetian maps (Bordon AD 1528) as being connected to the sea, can provide evidence of the geological
settings and landscape evolution of the area. In this study, we investigate the development of Akrotiri Salt Lake through a series of cores which penetrated the Holocene sediment sequence. Sedimentological, micropaleontological (benthic foraminifera and ostracods) analyses and geochronological studies performed on deposited sediments, identifying the complexity of the evolution of the Salt Lake and the progressive change of the area from maritime space to an open bay and finally to a closed Salt Lake.

Three main aquifer systems developed on Kythira Island include (Pagounis, 1981; Pagounis & Gertsos, 1984, Danamos, 1991; Koumantakis et al., 2006):
The porous aquifer system in Neogene and Quaternary formations.
The karstic aquifer system in the carbonate formations of the Pindos and Tripolis units.
The aquifer system (both shallow and deep) in the fractured hard rocks mainly of the Phyllites – Quartzites unit.
The main discharge of the aquifer systems takes place in coastal and submarine brackish springs around the island, except for its northern part where the Phyllites – Quartzites unit outcrops and its central part where springs of small capacity discharge the carbonate formations of the Pindos unit.
The municipal water supply of Kythira has been reinforced by a series of projects and interventions, focusing on the summer touristic period, when water demand surpasses by far water availability, mainly consisting of new deep boreholes.
Precipitation is the direct recharge of the three aforementioned aquifer systems while indirectly lateral discharge occurs in places between adjacent and tangential aquifer systems and from the streams runoff as well.
On August 4, 2017 a shrub, rather a forest fire broke out close to the island hospital; it expanded rapidly due to strong winds blowing in the area and raged out of control for four days, inducing considerable damage. The size of the fire-affected area was about 20km2, 16km2 mainly of shrub and 4km2 of agriculture land.
For the detailed evaluation of the geo-environmental impact of the aforementioned fire to the aquifer systems of the Kythira Island concerning the quantitative and qualitative degradation seventeen municipal water points were finally selected for further hydrogeological study.
The water points monitoring network were used in September 2017, June 2018 and October 2018 for measurements of the water tables heads and springs discharges while water samples were collected and chemical, trace elements and microbiological analysis were carried out.
The impact of the fire on the quantity of the aquifer systems of the wider fire-affected area could not be fully clarified and there was indirect evidence of their recharge (it remains unknown its rate compared to the recharge before the August 2017 fire) during the three field trips such as:
Fluctuation of the measurements of the water table heads.
Fluctuation of the measurements of springs discharges.
Fluctuation of the measurements of boreholes hydrometers.
Changes to the hydrochemical facies of the Piper’s, Durov’s and Stiff’s diagrams of the collected water samples.
The results and the evaluation of the chemical and trace elements showed that there was no impact of the fire on the quality of the wider fire-affected area aquifer systems. However, microbiological analysis from the Mylopotamos spring showed qualitative degradation, due to human activities in the wider area preexisting the August 2017 fire (Pagounis, 1981).
For the sustainable water resources management of the wider fire-affected area new projects were proposed in order to prevent phenomena that favors the runoff instead of infiltration which lead to the restriction of the recharge of the three main aquifer systems, such as works of artificial recharge.
Platis Gialos Bay located at the Southern part of Sifnos Isl. and his length is determined at 1.000 m, with SE direction. The coast of Platis Gialos Sifnos has been under erosion and permanent coastal retreat for several years, especially at the central and west part of the beach. The main causes of coastal erosion are anthropogenic.This paper focuses most intently on the geomorphological and sedimentological dynamic processes of the Bay which forming the current situation. For this reason a number of tasks took place in order to determine the level of disturbances of this dynamic equilibrium. This study included two phases of survey for two different periods (summer/winter). The first phase deals with the geomorphological and sedimentological coast characteristics, and includes: i) long-term geomorphological evolution of the coastal zone through the analysis of satellite images (Google Earth), in order to estimate the intensity of coastal erosion. ii) topographic sections at the surface of the coastal zone, through D-GPS (Spectra Precision SP80 GNSS Receiver), perpendicular to the coastline, iii) sediment sampling in the subaerial coastal area, iv)
analytical recording and mapping of the summer and winter shorelines via the D-GPS, v) the situation of the potential feeders of the shore with materials, necessary for the formation of an alluvial beach, and vi) recording of land uses (Fig.1). The second phase, includes the geomorphological and sedimentological characteristics of the marine area, in particular: i) topographic sections of the bottom surface until the depth of 1.5 m, through D-GPS, perpendicular to the coastline ii)sediment sampling in the subaquatic marine area, iii) data of the numerical recomposition of the wind and wave conditions of the study area, iv) bathymetric eco-sonar data (Lowrance LCX-15MT), v) side-scan single beam eco-sounder (StarFish 450), to determine the seabed morphological features of the bay and, vi) substrate component mapping (Fig. 1). Laboratory analyzes were followed by the methods of dry granulometry, in order to categorize it, in different types on the basis of Folk & Ward (1957) method through GRATISTAT (v.8) software.
The disastrous phenomenon of aseismic ground fissures along the eastern Thessaly basin has deteriorated since 1989. The main reason for these fissures is the over-pumping, which leads to differential vertical compaction of the aquifer system and subsidence on the land surface. In this paper, we present the results of a combined geophysical survey applied in the area (VES and TEM soundings), in order to investigate the subsurface geological conditions. The geological regime of the area is comprised of the alpine basement, transgression formations and finally a package of post-alpine deposits with respectful thickness. A peudo-3D representation of resistivity maps for several depths of investigation was produced. Additionally, a dataset of deep boreholes was used for the calibration of the geophysical data. All the borehole and sounding interpreted data were grouped into three categories in order to produce the Lithology Model of the area. The alpine bedrock was adumbrated only at the southeast and central part of the basin, where we do not observe ground fissures. The absence of alpine bedrock for depths up to 300 meters, the thick and coarse-grained deposits and finally the over-pumping seem to contribute to the creation of the ground fissures.
Mediterranean Temporary Ponds (MTPs) are shallow water bodies which are characterized from a short wet period and their small size (Zacharias et al., 2007). MTPs of Europe have are under an effective protection status, as a result of their identification as a priority habitat (Annex I code 3170*) in the EU Directive 92/43/EEC (Habitats' Directive). These ponds are very delicate ecosystems regarding their hydrological and geochemical characteristics. Due to their small size, they are open to random destruction or other unpredictable dangers. Although small in size, MTPs are complex ecosystems where topography, soil, water and hydrological conditions and microorganisms are closely connected (Zacharias et al., 2007; Stamatakis et al., 2015). The conservation and restoration of such ecosystems is very difficult because of their unique characteristics. The most common threats for MTPs include destruction of the hosting area through human and animal pressures, hydrological disturbance, fire and generally changes in ecological conditions resulting in an increase of competitive plants, nutrition influx, toxic contaminants and wastes, sedimentary deposit filling, exotic-invasive fauna and flora and negative effects from domesticated or hunted fauna (Dimitriou et al., 2006).
For several years, Greece has set as a priority the strengthening of maritime tourism, such as the tourism of yachts for which tourist marinas have been created. The most important marinas of the country include the “Glyfada Marina”, whose works began on the coastal front after 1960, thus changing the area’s shape and planning. The main objective of the present work is to investigate the improvement measures and prospects for the development of the “Glyfada Marina” consisting of four basins, being one of the most beautiful and developed marinas in the country since it is an important attraction for tourist yachts. For this reason, on-site visits to the port area were carried out, both on the sea and on the coastal part of the coastal zone, in order to record the current situation, so as to reach as accurately as possible the characteristics and the range of the internal port works and facilities of the aforementioned tourist port. Furthermore, any deficiencies or failures that need improvement are presented, labeled and classified in order to continue unhindered activities in the marina area. Finally, improvement and upgrading measures are proposed that can contribute positively to the tourist and economic development of the port and the municipality of Glyfada in general.
Beachrocks are consolidated sedimentary formations and are composed of coastal sediments, which are cemented through the precipitation of carbonates. The lithification takes place in the intertidal zone and can include various sediments, such as sands and gravels of clastic and biogenic origin. This study deals with the cements’ mineralogical and geochemical features of a beachrock outcrop and its aim is the contribution for further understanding on the cementation process of beachrocks. (e.g. Vieira and Ros, 2007; Vousdoukas et al., 2007; Karkani et al., 2017).
The generation of rock cavities and especially of those created under karstic procedures is a matter of research for the last decades. A high-resolution subsurface morphology could be produced after scanning the entire cave with state-of-the-art equipment based on Light Detection And Range technology. A handheld laser scanner was used for acquiring points with projected coordinate information (X,Y,Z) covering the entire show cave of Koutouki (Athens, Greece), including its hidden passages and dark corners. The point cloud covers the floor, the walls and the roof of the cave, as well as the stalactites, stalagmites and the connected columns that constitute the decoration of the cave. The absolute and exact placement of the point cloud within a geographic reference frame gives us the opportunity for three-dimensional measurements and detailed visualization of the subsurface structures.
The results of Structure-from-Motion techniques in order to quantify the ground surface deformation due to the massive landslide that occurred at the lignite open pit in Amyntaio, Greece on June 10th 2017, are presented in this paper. This unexpected slide damaged the entire westernmost marginal area of the pit, significant number of buildings and infrastructures (incl. road network, powerlines, biological treatment, houses etc.) of the nearby village of Anargiri, as well as agricultural land at the head of the landslide. We generated a very high-resolution surface topography and corresponding co-registered ortho-rectified images covering a total area of 2 km2 by analyzing images acquired from Remotely Piloted Airborne Systems (RPASs). A high resolution (0.13 m) Digital Surface Model (DSM) was produced after photogrammetric processing, serving as a reference dataset for comparison with other surveys realized in December 2017 and September 2018. We compared the centimeter-resolution DSMs acquired during the post landslide periods, quantified the overall ground deformation and finally delineated regions of potential risk.
A variety of remote sensing tools have been extensively used in the past years for landslide detection and mapping purposes. In addition, detection and mapping of landslide and rockfall events using remote sensing products has been proved to be an effective approach to provide landslide inventories (Scaioni et al., 2014). However, most of the studies are lacking valuable semantic information about landslide elements and how they react with the surrounding environment; natural and man-made primitives. In addition, post classification object-based approaches have been proved to result in better accuracies compared with the pixel-based (Martha et al., 2011). Lately, innovative close-range remote sensing technology such as Unmanned Aerial Vehicle (UAV) photogrammetry and Terrestrial Laser Scanning (TLS) are widely applied in the field of geoscience due to their efficiency in collecting data about terrain morphology rapidly. Their main advantage stands on the fact that conventional methods are mainly collecting point measurements such as compass measurements of bedding and fracture orientation only from areas that were accessible. Aerial platforms are capable to overcome technical issues such as potential occlusions and unfavorable incidence angles due to their ability to capture imagery from multiple positions and with different angles. Nowadays, UAVs tend to be more flexible and powerful tools for landslide and rockfall investigations compared to TLS, due to their low-cost and ease of transportability in harsh environments but also with technology advances such as maintaining of Real Time Kinematic (RTK) positioning. An important factor of their usefulness is their capability to offer unprecedented spatial resolution over wide inaccessible areas, maintain a variability of different sensors (optical, laser, thermal, multispectral) and great ability to reach remote areas and acquire data as close as the user defines. UAVs applications are widely used in post-disaster situations for emergency support, in infrastructure monitoring, in natural resources management, in geohazard monitoring etc. (Corominas et al., 2016; Vassilakis et al., 2019). The latter proves that UAV market has been rapidly growing over the last decade and in future more applications will be introduced in the public. Thus, rapidness and efficiency of Structure-from-Motion (SfM) technology in landslide management provides numerous advantages such as creating landslide inventory maps providing 3D information of large areas.

This research aims to demonstrate the applicability of UAV technology for automated semantic labeling in managing landslide and rockfall hazard in mountainous environments during emergency situations. SfM photogrammetry in addition to high accuracy RTK-GNSS ground control point establishment, is used to provide detailed 3D point clouds describing the surface morphology of the landslide and rockfall elements. The proposed methodology was divided in five main working phases. The first phase includes designing and execution of an optimal UAV flight planning to collect accurate 3D data. During the second phase, the pre-processing and raw data preparation such as point cloud filtering and elimination of ambiguities is taking place, while at the next phase an image segmentation using the 3D point cloud RGB information is created. The main task was focused on identifying the specific landslide elements by using an object-based approach. Based on Object-Based Image Analysis (OBIA), a sequence of image-based processes was applied, including multi-scale object segmentation, spectral, morphometric and contextual information extraction aiming to detect the landslide among other features. The next phase was set up for object classification in meaningful and homogeneous landslide classes (e.g. scarp, depletion zone, accumulation zone) which are spatially connected by introducing contextual information in the ruleset. The proposed methodology presents the effectiveness and efficiency of UAV platforms to acquire accurate photogrammetric datasets from intense relief environments and complex surface topographies by providing a holistic assessment and characterization of the failure site based on semantic classification of the landslide and rockfall objects. Results have demonstrated the capabilities of combining UAV platforms with computer-based methods for rapid and accurate identification of valuable semantic information subjectively and even from inaccessible areas of the landslide and rockfall body.
Akrotiri Salt Lake is located 5km west of the city of Lemesos, in the southern-most part of the island of Cyprus. The palaeogeographic evolution of the Akrotiri Salt Lake presents a great scientific interest, especially during the Holocene where the eustatic movements combined with local active tectonics and climate changes have developed a unique geomorphological environment. The Salt Lake, today a closed lagoon, which is depicted in Venetian maps (Bordon AD 1528) as being connected to the sea, can provide evidence of the geological settings and landscape evolution of the area. In this study, we investigate the development of Akrotiri Salt Lake through a series of cores which penetrated the Holocene sediment sequence. Sedimentological, micropaleontological (benthic foraminifera and ostracods)
analyses and geochronological studies performed on deposited sediments, identifying the complexity of the evolution of the Salt Lake and the progressive change of the area from maritime space to an open bay and finally to a closed Salt Lake.

In this work we study the electromagnetic scattering by a magnetized cold plasma body, using a surface integral equation (SIE) formulation. To solve the problem, we express the fields inside the anisotropic region using appropriate discrete eigenvalue expansions and, applying the boundary conditions on body's surface, we obtain infinite sets of inhomogeneous algebraic equations from which, upon truncation, the expansion coefficients of the internal field are computed. Then, the expansion coefficients of the scattered field can be evaluated, as well as the bistatic scattering cross section. To conclude on the method's validity, we compute the cross sections, for different values of parameters, for prolate spheroidal bodies, and compare with the results obtained by the HFSS commercial software.
Giannikopoulou K, Evelpidou N, Harris S, Poulos S. Seafloor structure of Argostoli Bay. RCG2019 “Geomorphology of Climatically and Tectonically Sensitive Areas”. 2019.Abstract
In order to investigate the formation processes of the seafloor of Argostoli bay (Cephalonia Island, Ionian Sea), an extended geological survey was conducted to gather details about the near-surface geological framework. Methods used for the survey include high resolution subbottom seismic profiles (29.4 line kilometers; EdgetechCHIRP system at frequencies 2-16 kHz) side-scan sonar backscatter surveys of the seafloor (approximately 67 line-km, Starfish 450F), single-beam bathymetry (approx. 67 line-km, Lowrance LCX-15MT Sonar system), and bottom sampling including bottom sediment grab samples (van veen grab sampler) and short sediment cores. The survey was focused at both ends of Argostoli Bay (i.e., Argostoli and Livadi inlets). Preliminary analysis of the sub-bottom profiles in the upper 12-20 m reveals a clear pattern of sediment layers, in both ends of the bay. The uppermost layers been deposited horizontally with small differences in their orientation in the area of Argostoli inlet,
while the presence of gas is more pronounced in Livadi inlet. Moreover, in Argostoli inlet a palaeo-surface is visible (probably the base of Holocene sedimentary cover) with minor channel features, likely indicating a shallow river valley. Side- scan mapping in combination with sediment samples and cores showed that the surface sediment consists mostly of finegained material, rich in organic matter over a gravel-lag deposit that may represent the transgressive surface in the area.
This study focuses on the sedimentological and morphological features of Vravrona Beach, East Attica, in order to determine the seasonal changes in the textural group classification of the costal sediments, as well as, changes in coastline position (Fig. 1). Additionally, Vravrona Beach has been chosen for the assessment of a potential coastal erosion, using the Coastal Vulnerability Index (CVI) through GIS technology, since several incidents of erosion have been identified during the past decades in the broader area of East Attica (Dimou et al., 2010).
For the composition of the beach profile in seasonal scale, cross sections were conducted along the beach from landward to seaward until approximately 10 m from the coastline. Beach width as well as the current coastline position for each season were measured with a differential GPS (DGPS). The land use at the landward upper limits of the study area were also measured. Along selected cross sections, sediment sampling was also conducted during January 2018 for the composition of the winter profile of the study area and during September 2018 for the composition of the summer profile of the study area.
Sedimentological analyses were based on grain size distribution for the analysis of unconsolidated sediments by sieving and statistical parameters such as sorting, skewness, mean and kurtosis were calculating using GRADISTAT v. 0.4 software in order to determine the sedimentological features of the study area and the transport mechanism at the time of deposition. The textural group of the samples was also determined by Folk and Ward (1957) classification.
The grain size analysis of the samples, collected between the upper limit of the beach and the coastline during summer period, show that the majority of grains is described as slightly gravelly sand and gravelly sand, but during the winter period the grains are between gravely sand and sand. The samples collected from the coastline until approximately 10 m seaward are mainly described as slightly gravelly sand and sandy gravel for both sampling seasons (Fig. 2).
DGPS measurements of coastline position indicate changes that varies between 4.38 m to 7.41 m with a maximum value at 8.27 m. In agreement to field observations, DGPS measurements indicate an accumulation of sediments at the northern part of the beach during the winter period, while during summer period there is an accumulation of sediments at the southern part of the beach.
The identification of the earthquake environmental effects by using various methods has become significant in recent years due to the fact that among others it serves as a valuable tool for revealing and highlighting sites of significant earthquake-related hazards. In the frame of the project entitled "Tilemachos - Innovative Operational Seismic Risk Management System of the Ionian Islands" included in the Priority Axis "Environmental Protection and Sustainable Development" of the Operational Programme “Ionian Islands 2014-2020”, the landslide, liquefaction and tsunami hazards in the Ionian Islands are analyzed and assessed by combining different methods. Landslide, liquefaction and tsunami inventories for all Ionian Islands were initially created. Along with the inventories, different thematic maps were used and combined in order to test the earthquake-induced landslide and liquefaction susceptibility and the tsunami hazard of the Ionian Islands. The main result is the identification of sites of significant earthquake-related hazards in the Ionian Islands. This study and its results could constitute a basic guide for the future urban design and planning and the sustainable local development since all scientists and agencies competent to the prevention and management of natural disasters can be informed and guided.
The west coast of Naxos Isl. was hit in 1956 by the Amorgos tsunami. This study aims to: a) determine the impact of a potential tsunami similar to the one that occured in 1956, based on the island's contemporary residential and tourist development, and b) explore whether the natural geomorphs (sand dunes) in the 3 study areas (Glyfada, Agios Prokopios, Chora of Naxos) can reduce the tsunami risk. Risk assessment was based on processing field data (differential GPS) and satellite images with GIS software. Furthermore, the dunes potential risk reduction has been evaluated. Results show that taller sand dunes and vegetation provides better tsunami protection to the coast of Glyfada, than the one of Agios Prokopios. Uncontrolled tourism development without any sand dunes protection measures underline their development and, consequently, increases the tsunami risk.
Coastal zone monitoring is essential in order to understand their evolution and incorporate sustainable coastal management practices. Frequent data collection is essential but often surveys can be costly and time-consuming. Several costly and time-consuming tools and techniques have been developed during the last few years for change detection and monitoring, allowing for both qualitative and quantitative analysis. In this study we present the ability of an off-the-shelf Unmanned Aerial Systems (UAS) coupled with Structure-from-Motion (SfM) photogrammetry to map and measure coastal features (e.g. shorelines). The UAS surveys taken place over three campaigns during Autumn 2017 (November), Spring 2018 (March) and Autumn 2018 (October) in Pinios river deltaic coast. The demonstrated UAS-SfM methodology produced remote sensing data with great spatial resolution which could be used to visually identify important parameters for coastal research and management at a fraction of thecost of other available techniques and. Even an off-the-shelf UAS is suitable for repeat surveys to assess spatial and temporal changes at small spatial extents and to better comprehend how these may be related with site-specific natural processes along the coast.
The Copernicus EO Programme offers information services based on vast amounts of satellite and in-situ data. This information content which is freely and openly available to all users, can directly impact teaching and learning systems by providing insights of our planet never available before. Specifically, the Copernicus ecosystem can enable students to develop a keen awareness of the intricate interrelationships that exist in the real world environment. The incorporation of Copernicus services and data in all levels of education is an ongoing effort which has been initiated with the establishment of the Copernicus Academy Network. Here, we present an application of Copernicus services into the Greek upper primary school curriculum, delivered in the form of “ready-to-use” hands-on activities. We use case studies from the latest natural disasters which have raised public awareness and are believed to be concrete examples of local events that are personally relevant to students, thus engaging them in an experiential learning process. The activity shown is related to the Athens’ devastating forest fires during the summer of 2018 (Mati, Kineta forest fires). We use the Sentinel-hub EO Browser tool to approach the issue of forest fires in urban compare to rural sites. Through simple concepts developed from these examples, the students are introduced to science subjects such as the interaction of light with matter, the reflection of light by different land surfaces, and the extinction of the radiation by atmospheric constituents. The interdisciplinary approach used in the suggested classroom activities promotes the UNESCO vision for education that helps students better understand the world in which they live by addressing the complexity and interconnectedness of environmental problems and thus promoting sustainable development concepts. Future work includes the use of additional natural phenomena and disasters or man-made emergency situations monitored by Copernicus in order to further promote a holistic approach in teaching and learning of Earth System Sciences. (e.g. floods, oil spills, algal blooms, desert dust outbreaks, volcanic eruptions etc.).
The aim of this study is to calculate the displacement rates of the coastline at the western part of the island, which is characterized of the escarpment coast. The shape of this coastal zone is caused mainly by tectonism which is very frequent in this wider area (Valkaniotis et al., 2018). The western coast of the island from Cape Agios Ioannis (NW) to the southernmost point of the peninsula, Cape Doukato is steep and precipitous, as a result of the high seismicity of the Ionian Sea area (Bornovas, 1964). Along this side of the island, several landslides and rock falls are observed. The situation changes only at the northern part of the island, with a distinctive coastal landform over the narrow zone called "Zostiras" (Leivaditis & Verikiou - Papaspyridakou, 1986).
This work was conducted using two different types of data. Historical analogue panchromatic aerial images of high resolution (Zuidam and Van Zuidam-Cancelado, 1979) and contemporary digital high resolution multi-spectral satellite images were combined for extracting the coastline at the time period of acquisition. The acquisition of the aerial photographs took place during 1945 and 2010, while the satellite images where acquired during 2016, 2017 and 2018 (Figure 1). In all cases the images were digitally processed and optically optimized in order to produce a highly accurate representation of the shoreline at each time period. All the data were imported in a Geographic Information System platform, where they were subjected into comparison and geo-statistical analysis (Tsokos et al., 2018). Several transects were drawn normally to the coast and the distance between them was set at every 200 m as the relative displacement of the coastline was calculated for each one of them.
In a way to achieve this, an extension of the ESRI ArcGIS v.10.6.1 software was employed as published by USGS and named Digital Shoreline Analysis System v.5 (DSAS). The DSAS extension (Thieler et al., 2009) lets the user define a constant straight line in a specific distance from the shoreline and take transects perpendicular to it among the evolving coastlines. The measurements give quantitative information on the change of the position of the shoreline, as well as more useful statistical data. Even if this seems to be an arbitrary value, it worked rather sufficiently at this almost 12 km long segment of the shoreline as it can be characterized as rather curvy and either a smaller value would result an oversampled area with transects intersect each other mixing the calculations or a larger value would result quite sparse transect locations without any representative outcome.

Οι υπάρχουσες έρευνες αναδεικνύουν ότι πολλοί μαθητές αντιμετωπίζουν δυσκολίες στα κλάσματα εξαιτίας της σύνθετης έννοιας αυτών καθώς και των λανθασμένων στρατηγικών που χρησιμοποιούν για τη διαχείριση τους. Σύμφωνα με σύγχρονα ερευνητικά ευρήματα, φαίνεται πως τόσο η εννοιολογική όσο και η διαδικαστική γνώση των κλασμάτων είναι απαραίτητες για τη μαθηματική ικανότητα. Στόχος της παρούσας μελέτης αποτελεί η ανάδειξη της ύπαρξης ή μη διαφοροποίησης στην επίδοση στα κλάσματα ολικά, εννοιολογικά και διαδικαστικά μεταξύ παιδιών με και χωρίς δυσκολίες στα μαθηματικά ή την ανάγνωση. Για τους σκοπούς της έρευνας χρησιμοποιήθηκε το MathPro test το οποίο αξιολογεί μαθηματικές δεξιότητες στους τομείς: επίγνωσης αριθμού, μνήμης, οπτικο-χωρικό και συλλογιστικής, ένα τεστ κλασμάτων που αξιολογεί την εννοιολογική και τη διαδικαστική γνώση, ένα ερωτηματολόγιο αξιολόγησης της επίδοσης στα μαθηματικά και την ανάγνωση από το δάσκαλο της τάξης και ένα τεστ αναγνωστικής ευχέρειας. Τα αποτελέσματα έδειξαν πως οι μαθητές με δυσκολίες στα μαθηματικά ή την ανάγνωση σημείωσαν στατιστικά σημαντικά χαμηλότερη επίδοση στα κλάσματα συνολικά, αλλά και επιμέρους στη διαδικαστική και εννοιολογική γνώση των κλασμάτων. Οπότε, προκύπτει η ανάγκη καλλιέργειας των δεξιοτήτων που απαιτούνται για τη διαχείριση κλασματικών αριθμών με σκοπό να αντιμετωπίσουν τις εν λόγω δυσκολίες οι μαθητές
Παρόλο που η σημασία αποτελεσματικής διαχείρισης των κλασμάτων έχει αναδειχθεί από πολλούς ερευνητές, οι προαπαιτούμενες μαθηματικές δεξιότητες για τον σκοπό αυτόν δεν έχουν διερευνηθεί ακόμη. Οι μέχρι τώρα προσπάθειες έχουν επικεντρωθεί κυρίως σε ευρήματα σχετικά με την εννοιολογική και τη διαδικαστική γνώση των κλασμάτων. Η παρούσα μελέτη στοχεύει να αναδείξει αυτές τις μαθηματικές δεξιότητες που σχετίζονται με την κλασματική γνώση σε μαθητές Ε ́ και Στ ́ δημοτικού. Σε αυτήν έλαβαν μέρος 99 μαθητές σχολικής ηλικίας κατά μέσο όρο 11,1 ετών οι οποίοι φοιτούσαν σε δημόσια δημοτικά σχολεία του νομού Ευβοίας. Στην έρευνα χρησιμοποιήθηκαν το MathPro test το οποίο αξιολόγησε επιμέρους μαθηματικές δεξιότητες των συμμετεχόντων ως προς την Επίγνωση Αριθμού, τη Μνήμη, την Οπτικο-χωρική ικανότητα και τη Συλλογιστική και ένα αυτοσχέδιο τεστ για την συνολική, εννοιολογική και διαδικαστική κατανόηση στα κλάσματα. Τα αποτελέσματα έδειξαν ότι από τις δραστηριότητες του MathPro test, τα Προβλήματα και οι Νοεροί Υπολογισμοί προβλέπουν τη συνολική και την εννοιολογική κλασματική επίδοση των συμμετεχόντων. Η διαδικαστική επίδοση στα κλάσματα φάνηκε να προβλέπεται από τους Κύβους, τα Προβλήματα και τους Νοερούς Υπολογισμούς. Συμπερασματικά, οι μαθηματικές δεξιότητες που σχετίζονται με τον Οπτικο-χωρικό τομέα και αυτόν της Συλλογιστικής φάνηκε ότι προβλέπουν την επίδοση στην κλασματική γνώση.

This study examines current research on the digital skills crisis and future skills demand, focusing on the gender dimension of the digital divide. Studies confirm that decades of equal opportunity policies, legislation and government initiatives have failed to increase women’s engagement in the STEM and ICT sectors. Statistics show no real improvement, women remaining a minority, despite the social inclusion movement in ICT and the widespread acknowledgement of the importance of digital skills required in EU workplaces. Industry needs to project and clearly define digital skill requirements. It is also vital to reshape STEM education to include the gender dimension, since social biases start at an early age. Accordingly, following a series of interviews, the study concludes with recommendations from four inspirational role models, successful women in ICT and information society: Nancy Pascall, Rosalie Zobel, Olga Stavropoulou and Elizabeth Pollitzer.
Key words: Digital Divide, Skill Gaps, Gender Gaps, Digital Literacy, Soft Skills
Urbanization has a significant impact on the surface environment and land surface temperature (LST) can be used as reliable indicator of the Surface Urban Heat Island effect that is caused by it. Here, the relationship between LST and the Athens urban landscape is investigated, using very high resolution airborne nighttime LST image data, obtained during the ESA’s 2009 THERMOPOLIS campaign for three typical summer days (warm day, day with strong Etesian winds and heat wave day). The landscape is represented by the percentage of built-up area coverage per spatial unit provided the European Settlement Map (ESM), spatially averaged on the European Urban Atlas land use map, both provided by Copernicus Land Monitoring Service. It is found that the LSTs exhibit statistically significant differences among the different urban land cover/land use (LCLU) classes, but also among the different days for the same LCLU. A modelled global relationship between LST and landscape can be constructed, though hot and cold spots exist, which indicate clustered areas with higher and lower LSTs. The hotspots coincide with the city centre area of dense fabric and the deviations are maximized with unfavourable meteorological conditions, i.e. heat waves and windless days.

A multidisciplinary analysis comprising neotectonic mapping, morphotectonic indices, applied geophysics and remote sensing techniques was applied in the area affected by the 2008 NW Peloponnese (Western Greece) in order to map the recently-recognized E-W striking Pineios River normal fault zone with a high degree of accuracy, and to better understand its contribution to the evolution of the ancient region of Elis during Holocene time.Quantitative constraints on deformation caused by the faulting were applied through the application of morphometric and morphotectonic indices including drainage network asymmetry, longitudinal river profiles and valley floor slope changes, the river sinuosity index (SI) of modern channels as well as mountain front indices including mountain front sinuosity (Smf) and percentage of faceting along mountain front (F%). All of the aforementioned indicated that the Pineios fault zone is a highly active structure.The study area consists mainly of a succession of Pliocene to Holocene sediments. Already published 230Th/238U dating of corals from the upper layers of the sequence indicates a Tyrrhenian age for samples spanning three complete sections from the footwall of the Pineios fault zone. The deposition ages were determined to be 103 ka for the Psari section (at an elevation of 40-45 m above a.s.l.), 118 ka for the Neapolis section (at an elevation of 60–65 m a.s.l.) and 209 ka for the Aletreika section (at an elevation of 140–145 m a.s.l.). The sampling sites that are located north of Pineios fault zone should be located on a single fault block because there is no sign of tectonic disruption between them. The ages of these dated samples correspond to oxygen isotope stages 5.3, 5.5 and 7.3. These stages represent high sea-level stands for the Mediterranean Sea and especially for the western coast of Peloponnese. In particular, at 103 ka sea-level was ~13 m below present sea-level, at 118 ka it was ~1 m below present sea-level and at 209 ka it was ~7 m below present sea-level. From the age of each sample and the sea-level change that has occurred since deposition, uplift rates for the footwall of the Pineios fault zone were calculated as ~0.26 mm/yr for the Psari area, ~0.50 mm/yr for the Neapoli area and ~0.64 mm/yr for the Aletreika area. The maximum uplift rate of 0.64 mm/yr occurs in close proximity to the fault zone. The areas with lower uplift rates are located much further to the north. Because all sample locations are inferred to be within the same fault block, this implies back tilting of the fault block toward north, in full agreement with the rotational block-faulting inferred from structural studies based on fieldwork in the surrounding area.

Remote sensing techniques offer the opportunity to study fire effects and vegetation recovery dynamics across large areas, providing essential information for effective management strategies development over fire-prone landscapes. Chios, the fifth largest of the Greek islands, has experienced recurring forest fires during the recent years, resulting to significant risk of environmental degradation. During the summer of 2016, the island experienced two severe wildfires, with the biggest one recorded in the southern part of the island. The affected area was mostly covered by maquis and phrygana (formations of low shrubs) (40.9%), while pine forests (Pinus brutia) represented 15.5% of the burned area.
The aim of this study was to estimate and analyze the state of post-fire vegetation recovery in the island of Chios following major fire events occurred during the summer of 2016. A post-fire 8-band WorldView-2 image was used for burned area mapping by employing a geographic object-based classification approach, followed by field campaign for assessing post fire vegetation recovery, which was conducted during summer 2017 by establishing reference plots in the main pre-fire vegetation types (maquis, shrublands and pine forest areas) within the fire-affected area.
A series of single and multi-temporal spectral indices including Normalized Burn Ratio, Normalized Difference Vegetation Index, Enhanced Vegetation Index and Soil Adjusted Vegetation Index, were derived from multi-temporal Sentinel-2 images. A random forest modelling procedure was performed for estimating post fire vegetation recovery within the burned area, as well as the areas of high risk erosion.
We identified dNDVI, EVI and the second red edge band of Sentinel-2 as the most important spectral variables for predicting vegetation recovery within pre-fire areas. In the case of pre-fire areas with maquis, post-fire NBR, EVI and NDVI were selected as best predictors. Finally, the results revealed that vegetation recovery is more pronounced within the pre-fire pine forest areas, while topographic and geological sub-strata factors were also found significant in defining post-fire vegetation recovery.
n July 25 and August 26 2016 wildfires broke out in the southwestern and central-western part of Chios Island(NE Aegean Sea, Greece), respectively. The first affected an area of approximately 47km2 and burned throughalmost 90% of olive groves and mastic trees, while the second broke out in a forested area and affected approximately6.6km2 of forest and farmland.A research aiming at the post-fire landslide susceptibility (LS) mapping of both areas was conducted. Morphologicaldata (slope, aspect, curvature, drainage network) derived from a 5m-DEM model of the areas was used.Lithological and geological data (lithology, tectonic structures) were digitized from previous field work maps.Land cover was derived from Worldview-2 satellite images before and after the fire events. Soil thickness was derivedfrom field survey observations within the fire-affected areas, road network from OpenStreetMap and rainfalldata resulted from related measurements derived from Chios meteorological station. Post-fire landslide inventorywas created after an extensive field survey of both areas before the beginning of the rainfall period (October 2016)and before the end of winter season (February 2017).Data classification of each factor according to their estimated LS followed, by using the reverse ranking method,where 1 is the least susceptible and 10 is the most one. Each category was normalized to 100% and the final rasterthematic maps of landslide controlling factors were produced. Finally, using numerical weight for each factor,which was assigned by the Analytic Hierarchy Process using Pairwise Comparison Method and according to theweighted linear combination, a map was generated where each cell has a certain post-fire LS index (LSI) value.The higher the LSI value, the higher the LS, whereas lower LSI value means lower LS.This procedure was repeated twice, first using pre-fire land cover and secondly using the severity of the fire events.The resulted maps, classified with natural breaks method, constitute the final pre- and post-fire LS maps of theaffected areas with five LS categories: very low, low, moderate, high and very high.Comparison of these two final maps showed, more or less, the same LS areas, but with LSI value enhanced. Thevalidated results showed good agreement between post-fire landslide occurrence and the produced post-fire LS maps.
The firsthand accounts of 252 European and American women travelers of the 17th to early 20th centuries in Asia Minor, Cyprus, Syria, Egypt, Greece and other Ottoman occupied territories confirm that thousands of women travelled and witnessed historic events. Women from Great Britain, France, Germany, Switzerland, Sweden, Austria and America explored, visited, resided as permanent residents, worked or served as volunteers, missionaries, educators, nurses, artists, governesses, ladies in waiting and servants of the western or eastern elite in different regions of the Ottoman Empire. This paper begins with a brief discussion on women travelers, subsequently focusing on 19th Century accounts regarding women’s contributions in times of conflict, exclusively from archival sources: the narratives of women volunteers, nurses, care givers and morale builders during the Crimean War (1853-1856), when the colonial experience encouraged female engagement. The accounts of English, French and German women who cared for the soldiers in the military hospitals of Constantinople and its environs reveal that women played key roles in social care, public health and hospital management, showing initiative and innovation in crisis management. The female accounts describe the British military and naval hospitals; the nurses duties and hardships (1,500 patients per 3 women: two lady volunteers and one nurse); the hundreds of women who followed their husbands to war; the demoralizing barrack system; the degrading social status and abuse of the English soldier’s wife and babies; the elevated status and protection enjoyed by the French soldier’s wife; the French military system. The female narratives argue that the French soldiers, as opposed to the English, are educated, industrious, productive and creative, adding to the general good. They spotlight the superiority of the French soldiers as regards their manners, morals, courtesy, organizational skills, patriotism and especially their respect and treatment of women.
Although forest fires are an integral part of Mediterranean forest ecosystems, they constitute one of the most devastating natural hazards in the region. Apart from the direct consequences, fires induce well-documented longer term effects in the geomorphological and hydrological processes, influencing environmental factors that in turn can affect the occurrence of other natural hazards, such as floods and mass movement phenomena.This work focuses on the forest fire of 2007 in Peloponnese, Greece that burnt 1773 km2, causing 78 fatalities and very significant damages in property and infrastructure and went down as the largest fire in the country’s record. It examines the occurrence of flood and mass movement phenomena, before and after this mega-fire and studies different influencing factors to investigate the degree to which the 2007 fire and/or other parameters have affected their frequency.Observational evidence based on several data sources collected during the period 1989-2016 show that the 2007 fire has contributed to an increase of average flood and mass movement events frequency by approximately 3.3 and 5.6 times respectively.Fire affected areas record a substantial increase in the occurrence of both phenomena, presenting a noticeably stronger increase compared to neighbouring areas that have not been affected. Examination of the monthly occurrence of events showed an increase even in months of the year were rainfall intensity presented decreasing trends.Although no major land use changes has been identified and chlorophyll is shown to recover 2 years after the fire incident, differences on the type of vegetation as tall forest has been substituted with lower vegetation are considered significant drivers for the observed changes in hydrogeomorphic response of the fire affected basins.The findings of this work are strong indications that future climatic change, with more frequent and severe droughts and storms will be a disastrous combination for the Mediterranean region.
A seismic risk model on a building block scale is presented for the earthquake prone city of Aigion (W. Corinth Gulf) by combining deterministic seismic hazard with Risk-UE LM1 structural vulnerability, assessed per building, taking into account site conditions approximated by Horizontal-to-Vertical-Spectral-Ratios (HVSR) from ambient noise. The stochastic finite-fault method has been applied to simulate strong ground motion from two close earthquake scenarios, capable of occurring within the seismotectonic frame of the area: (a) a repetition of the 1995, June 15 (Mw=6.4) devastating earthquake and (b) a repetition of the 1861, December 26 earthquake of Mw=6.7 on the East Heliki Fault (EHF). The applied methodology provided comparable pattern with the real damage distribution of the 1995 earthquake, highlighting outlooks toward earthquake preparedness and riskmitigation purposes.

Στο απόηχο της Ρωσικής Επανάστασης, το 1918 ιδρύθηκε στις ΗΠΑ η ελληνική κομμουνιστική εφημερίδα «Η Φωνή του Εργάτου» με στόχο να συσπειρώσει τον ελληνικό εργατικό κόσμο. Στους κόλπους της εφημερίδας γεννήθηκε ο πρώτος γηγενής σοσιαλιστικός θίασος στη Νέα Υόρκη, ο «Θεατρικός Εργατικός Όμιλος». Ο «Θεατρικός Εργατικός Όμιλος», αυστηρά προσανατολισμένος στις κομμουνιστικές αρχές, συμμετείχε σε γιορτές συλλόγων, σε χοροεσπερίδες με αφορμή την επέτειο της Ρωσικής Επανάστασης ή υπέρ της εφημερίδας «Η Φωνή του Εργάτου», η οποία το 1923 μετονομάστηκε σε «Εμπρός». Απ’ τους κόλπους του «Θεατρικού Εργατικού Ομίλου» γεννήθηκαν πολυάριθμοι σοσιαλιστικοί ερασιτεχνικοί όμιλοι (π.χ. ο «Σπάρτακος» και ο «Λόκαλ 70» των Γουναροεργατών).Ταυτόχρονα προέκυψε ένας πυρήνας θεατρικών συγγραφέων, προερχόμενοι από τους σοσιαλιστικούς θιάσους, οι οποίοι συνέγραψαν έργα επαναστατικά νατουραλιστικά, τα οποία αναδεικνύουν τις κοινωνικές αδικίες, την εκμετάλλευση των εργατών, την ανισότητα, το ρατσισμό και γενικότερα όλη την κοινωνική παθογένεια της Αμερικής. Το παρόν επιστημονικό άρθρο αναδεικνύει το σοσιαλιστικό ρεπερτόριο, τη δραματουργία των στρατευμένων συγγραφέων και τις δράσεις των σοσιαλιστικών θιάσων στις ΗΠΑ από το 1918 έως τη δεκαετία του 1940.
Η παρούσα ανακοίνωση αναδεικνύει τη ζωή και το έργο τριών Επτανήσιων μουσουργών, οι οποίοι έζησαν και έδρασαν στις Η.Π.Α. κατά το πρώτο μισό του 20ού αι. Α) Ο Κερκυραίος Λορέντζος Καμιλιέρης (1877-1956), συνθέτης, διευθυντής ορχήστρας και χορωδίας διακρίθηκε στη Νέα Υόρκη με την ίδρυση και λειτουργία της μακροβιότερης χορωδίας στις ΗΠΑ, της People’s Chorus. B) O επίσης Κερκυραίος Σπύρος Μπεκατώρος (1862-1938), συνθέτης, διευθυντής ορχήστρας και καθηγητής μουσικής, εγκαταστάθηκε στο Σικάγο και στη Νέα Υόρκη, όπου για τριάντα χρόνια υπηρέτησε τις ελληνοαμερικανικές ορχήστρες. Γ) Ο Κεφαλλονίτης Ιωάννης Βεργωτής (1875-;) συνθέτης, λιμπρετίστας και διευθυντής ορχήστρας ίδρυσε στη Νέα Υόρκη ελληνοαμερικανικό οπερετικό θίασο, όπου παρουσίαζε προσωπικά του έργα.
The purpose of the study is the determination of the morphodynamical processes and the changes of the shoreline of Marathon Bay, which is located at northeast Attica. The area was lagoon 3.500 years BP (Pavlopoulos et al.2006) and it is characterized by low elevations and smooth slopes.
The survey of the coastal and marine geomorphology was carried out by acoustic scanning of the seafloor with an echo sounder and sonar side scan topographical sections perpendicular to the shoreline and collection and analysis of surface sediments. The quantification of long-term shoreline displacements (Thieler et al. 2009) was carried out by comparing historical and recent aerial photographs (1945, 1960, 1969, 1988, 1996, 2001, 2010,), satellite imagery (6/2015, World View 2) and the imprint of the coastline (3/2013) with real time kinematic digital global positioning system (RTK DGPS). The estimation of rate and volume of the sediments transportation was realized by a hydrodynamical model (MIKE 21 Flow Model FM).
At the north section of the area, near the estuary of Kainourio stream, and the lagoon’s draining channel, the maximum rates of coastal retreat are noticed (̴0,35m/year).
The exposition of the coast to the southern waves, the reduced sediment supply from local rivers, due to the Marathon’s Dam and secondly of the morphology of their riverbeds, they have been filled because of the sea level rise the last 50yrs (IPCC, 2007). The lack of sediment supply, the sediment's composition and the morphological appearance of the submarine basin at the northeast of the Bay are mainly responsible for the coastal retreat along with the sea level rise.
Ο σκοπός της παρούσας διπλωματικής εργασίας είναι ο εξής: (α) να συγκρίνει την αυτοεκτίμηση των δυσλεκτικών και των μη δυσλεκτικών παιδιών ηλικίας 11-12 ετών,(β) να συσχετίσει την αυτοεκτίμηση των παιδιών με την αποδοχή-απόρριψη από τον/την εκπαιδευτικό και (γ) να συγκρίνει τους παραπάνω παράγοντες ως προς το φύλο των συμμετεχόντων. Το δείγμα της έρευνας προέρχεται από 6 δημόσια σχολεία της Α’ Περιφέρειας της Αττικής και αποτελείται από 118 μαθητές ελληνικής καταγωγής (21 δυσλεκτικοί & 97 μη δυσλεκτικοί) που φοιτούν στην Ε’ και ΣΤ’ Δημοτικού και τους δασκάλους τους (N = 12). Τα μέσα συλλογής των δεδομένων για το δείγμα των μαθητών αποτελούν τα εξής δύο ερωτηματολόγια: «Πώς Αντιλαμβάνομαι τον Εαυτό μου ΙΙ» (Μακρή-Μπότσαρη, 2013) και «Child Teacher Acceptance-Rejection/Control Questionnaire-Short Form» (Kourkoutas, Propersi, & Georgiadi, 2013). Το δείγμα των εκπαιδευτικών συμπλήρωσε το ερωτηματολόγιο «Κλίμακα της Σχέσης Δασκάλου-Μαθητή» (Galanaki & Vassilopoulou, 2007) για τον κάθε μαθητή. Τα βασικά αποτελέσματα της έρευνας είναι ότι η αυτοεκτίμηση των δυσλεκτικών παιδιών είναι χαμηλότερη από αυτή των μη δυσλεκτικών, όπως επίσης και ότι η αυτοεκτίμηση των μαθητών συσχετίζεται με την αποδοχή-απόρριψη από τον/την εκπαιδευτικό. Τέλος, ένα βασικό εύρημα είναι ότι η αποδοχή-απόρριψη από τον δάσκαλο βιώνεται διαφορετικά από τους μαθητές ανάλογα το φύλο τους, ενώ από την μεριά του εκπαιδευτικού, το φύλο του μαθητή δεν επηρεάζει τη μεταξύ τους σχέση.
This research project investigates the influence of a number of economic and financial variables on the profitability of Greek enterprises from 2006 to 2013, namely: annual revenue, exports as a binary variable, number of employees, sectoral composition, investments and founding year. Three models were tested using linear stepwise regression as well as logistic regression. The fit to the data is low, indicating that other important factors, in addition to those tested, influence the development of corporate profits more. Running the models for individual years we see that in the years 2010 and 2011 mark a shift in the direction of the relation of several of our variables to profits (such as the age of the enterprise and the number of employees). The full application of austerity policies because of the crisis may be the explanation for that, indicating that the crisis did not have a unified influence on profitability. More importantly statistically significant results are observed in relations which conflict with economic theory, namely exports are negatively correlated to profitability (Model 1) or not correlated at all (Model 2). Our models do not contribute to understanding the determinants of profitability but rather the difficulties to identify smooth profitability patterns at times of crisis and austerity. The research is still in progress as we strive to improve the explanatory power of the models, by expanding the number of variables and using additional statistical methods.

The present paper tries to devise a rating system for evaluating the likelihood of success of publicly supported companies. In recent literature we encounter quality indexes, composed of variables like name selection, registration location, intellectual property rights etc., which predict fairly accurately startup success. Unfortunately such indexes can only be compiled for countries with open administrations facilitating access and cross-checking of company data. We argue, however, that it is countries with less open administrations that have the highest need of ex ante quality assessment in order to maximise the public return of investment of state support mechanisms. This is why we suggest that, rather than giving up research on the likelihood of company growth because of lack of systematic open data, we can test firm dynamism based on public domain information. Dynamic firms, we assume, will be more likely to grow. The Web and Social Media data, which have until now mostly been used for marketing purposes, can be a valuable source of information for our purpose. We attempted to use the digital footprint as a proxy for the dynamism of SMEs and startups. Using State Aid schemes (i.e. public support to profit-oriented companies) in the period 2007-2013 in Greece we constructed a sample of 2000 companies and rated them individually for their presence (or not) in Facebook, LinkedIn, a site (with or without registered domain name), e-mail with domain name, references, size of the site, sales via web, search function, communication, regular update, FAQs and after sales support availability. Testing for sector, region, type of company and type of support scheme we find a statistically significant result for the more dynamic sectors, type of schemes and type of companies, while the regional level appears to be irrelevant, as companies in all regions demonstrate a fairly unified digital presence.
Thousands of European and American women provided their services, lobbied, raised funds, food supplies and clothing to support the Greek Revolution. Along with the relief activities of the 1820’s and 1830’s, the great interest in Greece produced a strong desire to send teachers and missionaries to Greece in Bondage. Women’s 19th century accounts examine theposition of the subjugated Greeks in the Aegean Islands and Asia Minor. European and American women—educators and philanthropists—worked for the advancement of female education. They even established schools for the preservation of Hellenic cultural heritage. This paper focuses on the first-hand accounts of 19th century European aristocratic and middle-class women volunteers, and specifically their social contribution during the Crimean War (1853-1856), when the English and French colonial experience encouraged female volunteerism. It spotlights the social service provided by English, French and German nurses and philanthropists—as agents of social change—who cared for the soldiers in the hospitals of Constantinople and its environs, concluding with their invaluable recommendations. The female accounts describe the British military and naval hospitals, hospital huts, nurses duties and difficulties confronted (1,500 patients per 3 volunteers); the Women’s Hospital; the French hospitals; the French military system; the Sisters of Mercy; the Sisters of Charity; the women who followed their husbands to war, including thedestitute wives and babies of the English soldiers. Astonishing are the accounts concerning the degrading social status of the English soldier’s wife as opposed to the respect and protection enjoyed by the French soldier’s wife.
The subject of this work is the investigation of the interaction between groundwater and seismic waves, resulting in liquefaction of the soil, a particularly dangerous phenomenon. Therefore, estimates of liquefaction potential can significantly contribute to the prevention of such effects and consequently to reduction of the seismic risk. The study area is Cephalonia Island, the most earthquake prone region of Europe. A dataset consisting of seismic ambient noise, accelerograms and datasheet from geotechnical boreholes, obtained after the 2014 earthquake crisis, has been analysed using a series of methodologies. Ambient noise analysis provided amplification functions, Vs30 models and synthetic time histories for numerous sites across the 2014 epicentral area. These were used for the seismic site characterization across the western part of the island and the estimation of the liquefaction potential in the coastal areas of Argostoli and Lixouri, where liquefaction phenomena were observed after the occurrence of the two strongest earthquakes in 2014. The results of the analyses are found to be compliant with the overall arrangement of the 2014 secondary earthquake effects, implying for strong site effects and interaction with the groundwater.
The absence of an epistemologically founded geopolitical analysis method that has been internationally observed was the motivation for writing the following contribution. The paper is divided into two parts: i) Definitions and Example analysis and ii) Determination of the Lakatosian Structure of the Systemic Geopolitical Analysis.

Virtual environments (VE) are virtual social spaces that provide powerful means for creating, activating and modifying virtual bodies—Avatars—without dependencies on biological factors,formal rules and explicit conventions. VE offer unlimited possibilities to create the desired body and express personal bodily preference in virtual sport spaces without restrictions regarding established roles and behavioural expectations. Such a VE is Second Life (SL) in which the user is represented by an Avatar. This study focuses on a virtual sport space: the Fitness Club of Second Life. It examines the rules and regulations of this virtual space along with the role of 26 Avatars as bodily representations, including their bodily behaviours-exercises-practices in the SL Fitness Club. The data for this study was selected through systematic observation of 26 Avatars (apx. 180 hours) during March, April and May 2015, followed by detailed descriptions of single phenomena. Regarding the structure of space and bodily behavior, the results indicate less differences between sport virtual spaces and sport physical spaces, the opposite of what we had originally assumed. According to the results, the Avatar Fitness Club appears to be a highly individualistic and narcissistic environment. Moreover, every user can perform his/her bodily activities in a rather liberating way, occasionally surpassing biological limitations. When the Avatars exercise they imitate the movements of the physical sport world, namely they mimic the physical body. Further studies are needed to show the influence of an Avatar’s performance-bodily exercises on the real user, the individual behind the computer screen.
RN24_09a_P: Science, Technology, Innovation & Society II (Time: 01/Sep/2017: 11:00am-12:30pm) ABSTRACT: Virtual environments (VE) are virtual social spaces that provide powerful means for creating, activating and modifying virtual bodies—Avatars—without dependencies on biological factors,formal rules and explicit conventions.

The development of the students’ research competence in a Distance Postgraduate Program is the main question of our report. Its investigation was attempted through the study of the postgraduate students’ representations in the Module French as Foreign/International Language Program of Hellenic Open University. Particularly, the questionnaire sent to the students of this Program, focused on the role of Written Essays carried out during it, in terms of the development of students’ research competence.
Ένα από τα σημαντικότερα ζητήματα που έχει να αντιμετωπίσει σήμερα η εκπαιδευτική κοινότητα είναι αυτό του εκφοβισμού (bullying). Ερευνητικά δεδομένα υπογραμμίζουν ότι το φαινόμενο του εκφοβισμού στο σχολικό περιβάλλον ανατροφοδοτείται με έναν περίπλοκο τρόπο και είναι άρρηκτα συνδεδεμένο με εξωσχολικούς παράγοντες όπως οι αλλαγές στη δομή της οικογένειας και στην ποιότητα των ενδο-οικογενειακών και διαπροσωπικών σχέσεων, η συνεχής και αυξανόμενη έκθεση των παιδιών στη βία τόσο αναφορικά με τα ΜΜΕ όσο και κατά την ενασχόλησή τους με συγκεκριμένα ηλεκτρονικά παιχνίδια κ.α. Από ένα μεγάλο αριθμό διερευνητικών προσεγγίσεων επισημαίνεται ότι η ποιότητα του σχολικού κλίματος, η σχολική συνοχή καθώς και ο άμεσα περιβάλλων χώρος του σχολείου παίζουν σημαντικό ρόλο στην εκδήλωση επιθετικών ενεργειών. Στον ελλαδικό χώρο, παρ’ όλο που έχουν πραγματοποιηθεί πολλές έρευνες για τον εκφοβισμό ως μορφή ενδοσχολικής βίας, δεν υπάρχουν ακόμα αρκετές μελέτες, που να διαπραγματεύονται και να διερευνούν το ζήτημα αυτό στις προοπτικές του μαθήματος της Φυσικής Αγωγής (ΦΑ). Η παρούσα μελέτη –ως επιμέρους προσπάθεια μιας εν εξελίξει εμπειρικής έρευνας— βασίζεται σε ανασκόπηση της σύγχρονης ερευνητικής βιβλιογραφίας και έχει σκοπό να αναδείξει και να επισημάνει τους σημαντικότερους παράγοντες που συμβάλλουν στην εκδήλωση του εκφοβισμού στις προοπτικές του μαθήματος της ΦΑ στον ελληνικό χώρο. Σύμφωνα με τη διεθνή βιβλιογραφία το μάθημα ΦΑ συμβάλλει θετικά στην ομαλή κοινωνικοποίηση και ενσωμάτωση των μαθητών στο σχολείο. Στις προοπτικές αυτές επισημαίνεται ότι οι Καθηγητές/τριες Φυσικής Αγωγής διαδραματίζουν καθοριστικό ρόλο στη δημιουργία θετικού κλίματος εφαρμόζοντας στρατηγικές και προγράμματα διαχείρισης διαπροσωπικών σχέσεων και συγκρούσεων. Ωστόσο από την άλλη πλευρά όπως διαπιστώνεται από τις σχετικές με αυτό το ζήτημα έρευνες που πραγματοποιήθηκαν σε άλλες χώρες, οι αθλητικές ή παιγνιώδεις ομαδικές δραστηριότητες που κατ’ εξοχήν χρησιμοποιούνται ως εκπαιδευτικό εργαλείο στη ΦΑ, δημιουργούν ευκαιρίες για στοχοποίηση κάποιων μαθητών/τριών εξαιτίας, μεταξύ άλλων, κάποιων ατομικών χαρακτηριστικών (π.χ. σωματικό βάρος, σεξουαλικό προσανατολισμό, φύλο, μειωμένο επίπεδο κινητικών δεξιοτήτων) τόσο από τους συμμαθητές/τριες όσο και από τον εκπαιδευτικό της ΦΑ. Η στοχοποίηση αυτής της μορφής αναδεικνύεται ως ένας καταλυτικός και ουσιαστικός παράγοντας εκδήλωσης εκφοβιστικών συμπεριφορών. Όπως προκύπτει από τα διεθνή ερευνητικά δεδομένα η ΦΑ αποτελεί ένα μέσον –ανάλογα με τον τρόπο που το οργανώνουμε και το διαχειριζόμαστε— τόσο για την καλλιέργεια και εκδήλωση του φαινομένου του εκφοβισμού όσο και για την άμβλυνσή του.

ΠΕΡΙΛΗΨΗ -- ABSTRACT
Οι έρευνες της έμφυλης διάστασης του κοινωνικού κεφαλαίου, μολονότι περιορισμένες, δείχνουν ότι οι γυναίκες παίζουν σημαντικό ρόλο στην ανάπτυξη και αναπαραγωγή του, αναλαμβάνοντας κυρίως εθελοντικές δράσεις κοινωνικής προσφοράς και δράσεις κοινωνικής επιχειρηματικότητας που συντελούν καταλυτικά στην κοινωνική και οικονομική ευημερία. Επιπρόσθετα τα αποτελέσματα μεγάλου αριθμού ποιοτικών ερευνών, οι οποίες επικεντρώνουν το ενδιαφέρον τους στις αλληλεπιδράσεις μεταξύ φύλου, αθλητισμού και επιχειρηματικότητας, δείχνουν μια θετική συσχέτιση μεταξύ των παραμέτρων αθλητική εμπειρία και επιτυχημένη ηγεσία. Η διερευνητική αυτή προσπάθεια προσεγγίζει τον αθλητισμό στις προοπτικές της θεώρησης περί κοινωνικού κεφαλαίου. Βασιζόμενη σε μια ενδελεχή ανασκόπηση της διεθνούς σχετικής βιβλιογραφίας, και στα αποτελέσματα ποιοτικής έρευνας (8 ημι-δομημένες συνεντεύξεις) που διενεργήθηκε το 2016-2017, στοχεύει να εξηγήσει το ζήτημα της υποεκπροσώπησης των γυναικών όσον αφορά στις θέσεις διοικητικής ευθύνης στους αθλητικούς θεσμούς και κυρίως να αναδείξει τα εμπόδια που λειτουργούν καταλυτικά για την εμφάνιση αυτής της υποεκπροσώπησης. Επικεντρώνει το ενδιαφέρον της στη γυναικεία συμμετοχή, που κατά κανόνα παραμένει μια ανεκμετάλλευτη πηγή κοινωνικής ενέργειας και η οποία υπό συνθήκες μπορεί να διευκολύνει ποικίλες διαδικασίες κοινωνικής ενσωμάτωσης. Επίσης διερευνά πιθανούς συσχετισμούς μεταξύ αθλητικής εμπειρίας και επιχειρηματικής δραστηριότητας. Υποκείμενα της έρευνας ήταν οκτώ εν ενεργεία και πρώην Ελληνίδες αθλήτριες, πρωταθλήτριες, ολυμπιονίκες και ακτιβίστριες—που έχουν διαπρέψει στην αθλητική ηγεσία και στο αθλητικό επιχειρείν. Τα αποτελέσματα δείχνουν ότι ο αθλητισμός προάγει δεξιότητες που είναι σημαντικές για την επιχειρηματικότητα και την ανάληψη δραστηριοτήτων διοικητικής μέριμνας και ευθύνης. Ωστόσο οι γυναίκες που ενεργοποιούνται στο χώρο του αθλητισμού και επιδιώκουν να αναρριχηθούν σε θέσεις διοικητικής ευθύνης ή να ασκήσουν επιχειρηματικότητα στον χώρο αυτό, έχουν να υπερβούν πολλά εμπόδια. Μεταξύ άλλων επισημαίνονται: (1) οι προκαταλήψεις και τα στερεότυπα που ακόμα είναι κυρίαρχα και προκύπτουν από τις ανδροκεντρικές καταβολές του αθλητισμού, (2) η έλλειψη γυναικών μεντόρων, (3) η έλλειψη γυναικών προτύπων, (4) οι άνισες ευκαιρίες εξέλιξης στην αθλητική ηγεσία σε σύγκριση με τους άνδρες, (5) η έλλειψη ισορροπίας μεταξύ επαγγελματικής και ιδιωτικής/οικογενειακής ζωής. Απάντηση σε αυτή την υποεκπροσώπηση αποτελούν προγράμματα που προωθούν, προβάλλουν, και δημιουργούν γυναίκες μέντορες και κοινωνικά πρότυπα όπως εκείνο της Ελληνικής Ολυμπιακής Επιτροπής (ΕΟΕ) και του Συλλόγου Ελλήνων Ολυμπιονικών (ΣΕΟ) «Κάνουμε Χώρο για περισσότερες γυναίκες στην Αθλητική Συμμετοχή, την Προπονητική Καθοδήγηση, και ειδικά τη Διοικητική Στελέχωση».

Beachrocks represents a coastal deposition in the intertidal area, and studying their properties may lead to create a model which identifies the conditions of their formation (paleo-environment). This paper focuses most intently on the cement material which is able to recover the paleo-environment conditions during diagenesis of such coastal sediment. We used optical microscopy, secondary electron microscopy
and Raman Spectroscopy to characterize the cement texture, mineralogy and chemistry in the beachrocks. The existence of pure calcite primarily controlled by the meteorite water, while Mg-calcite appears between the lower meteoric and the upper marine phreatic zone. Finally, the presence of aragonite associated with the marine phreatic to lower marine vadose environment.

This region of western Greece has been frequently activated during the last decade, providing a large amount of enhanced quality new seismic information that was recorded by the Hellenic Unified Seismological Network (HUSN). In this work, the results of earthquake relocation, stress inversion and seismic traveltime tomography are presented, towards investigating the geodynamics of the study area. Inversion of ~2300 focal mechanisms indicates obliquity by 30 ̊ between shearing and the maximum horizontal stress along the major strike-slip faults, consistent with clockwise crustal rotation. Within the lower crust, the stress field appears to be constrained by larger scale deformation. Seismic velocity anomalies have been resolved by regional body-wave traveltime tomography, applying an iterative tomographic inversion scheme using phase data from more than 5000 seismic events. Preliminary 3D tomographic models indicate the presence of gross structures related with the western Hellenic Trench, the Cephalonia Transform Fault (CTF), the Aitoloakarnania shear zone, the Corinth Gulf and the Messinia graben. Dipping towards the east and segmentation of CTF between Cephalonia and Lefkas is evidenced by the resolved anomalies while a predominant NE-SW oriented low velocity zone observed in central Peloponnesus, related with dextral strike-slip faulting, marks a 90° rotation of the extensional stress direction that is found to occur at both sides.
This work describes the outcome of two field surveys in Lefkada Island, after the 17.11.2015 earthquake of Mw6.4 at its southwestern peninsula. Geo-environmental effects were observed throughout the western flanks of the mountain massif, parallel to the activated fault. Structural damage was mainly observed in the epicentral area where macroseismic intensity was assessed as VIII, based on registered damage and assumed vulnerability per building typology. Both modern and traditional buildings exhibited notable seismic performance. The distribution of the damage per building category present in the affected area is presented, based on site surveys and post-seismic usability characterization by the local Earthquake Rehabilitation Organization. The survey highlights the frequent presence of the so-called “pontelo” dual system at both ground floor and two-story stone masonry buildings at the western mountain villages. This structural type, unique within the Greek territory, revealed significant seismic performance and the need of engineering restoration measures is underlined.
The long term change of the shoreline is a phenomenon, which is factored in the design of construction projects along the coastal zone. This study presents a meth-odology that aims to quantify the shoreline displacement rate. The described meth-odology involves the interpretation of different remote sensing data types, which make up a quite dense time series of representations for the coastline spanning from 1987 to 2012. The representation of the shoreline is based on geometrically corrected (ortho-rectified), historical, analogue, panchromatic, high resolution aerial photos of the area (1987, 1996) and latest generation, digital, multispectral, high resolution satellite images (2000, 2008, 2012). In all cases the images were digitally processed and optically optimized in order to produce a highly accurate representation of the shoreline in each time period. All the data were imported in a Geographic Information System platform, where they were subjected to comparison and geo-statistical analysis. A large number of sections perpendicular to the coast (every 100 meters) was drawn and the relative motion of the coastline was calcu-lated for each of them. The average rate of the calculated erosion is in the order of 24mm/year whilst extreme rates of 1m/year were also observed in specific posi-tions.
Στον ελληνικό περιοδικό τύπο του 19ου αιώνα κυριαρχεί η αρθρογραφία για την Ελληνική αρχαιότητα αντανακλώντας το φλέγον ζητούμενο της εποχής, τη σύνδεση του νεώτερου Ελληνισμού με την ελληνική αρχαιότητα, με σκοπό την δημιουργία μιας εθνικής ταυτότητας, την πολυπόθητη διαμόρφωση της εθνικής συνείδησης, συνυφασμένη με τον ευρωπαϊσμό. Η ελληνική αρχαιότητα αποκαλύπτεται στους φιλομαθείς του νεοσύστατου κρατιδίου μέσα από τις μεταφράσεις άρθρων των αρχαιολατρών μελετητών της Δύσης. Ήδη από τα μέσα του 18ου αι. η δυτική αρχαιοφιλία απασχολείται συστηματικά με όλες τις εκφάνσεις του αρχαιοελληνικού πολιτισμού, τις οποίες –ως επακόλουθο- ενσωματώνει στη σύγχρονη ευρωπαϊκή σκέψη και πνευματική δημιουργία, παράγοντας διακείμενα σε όλους τους τομείς των γραμμάτων και των τεχνών (φιλοσοφία, λογοτεχνία, θέατρο, μουσική, καλές τέχνες, αρχιτεκτονική). Το άρθρο πραγματεύεται μία δημοσίευση στην Ιωνική Μέλισσα στις 16/11/1850, το οποίο τιτλοφορείται «Οιδίπους Τύραννος» και υπογράφεται από τον «Πείσανδρο», πιθανό ψευδώνυμο –δίχως να έχει επιβεβαιωθεί η πληροφορία- του Ικέσιου Λάτρη (1799 - 1881), Σμυρναίου λόγιου, αγωνιστή του 1821 και πολιτικού της νεοσύστατης Ελλάδας. Στο εν λόγω άρθρο, το οποίο αναφέρεται στα θέματα της πρόσληψης του αρχαίου θεάτρου, αναπτύσσεται ένας πρώιμος προβληματισμός, για τον οποίον όμως προτάσσονται λύσεις και περιγράφεται ο τρόπος υλοποίησης μίας πολιτικής στρατηγικής.
Sea level indicators, such as tidal notches and beachrocks, may provide valuable information for the relative sea level changes of an area. Beachrocks in particular have received various arguments concerning their use as reliable sea level indicators and their formation environment. This work focuses on the coasts of East Attica in order to trace the palaeoshorelines of the Upper Holocene through the study of beachrocks. The coastal zone was surveyed in detail by snorkelling and diving, in order to locate, map and sample beachrocks. The samples were studied under a SEM, which showed that the beachrocks are mainly composed of quartz grains, a few calcites and feldspars, while the carbonate cement is characterized with the presence of MgO at percentages between 5 and 7.8%. Based on correlations with published drillings in the study area, the studied beachrocks should not be older than 2000 years BP.
Καμπερίδου Ειρήνη. ΑΘΛΗΤΙΣΜΟΣ ΚΑΙ ΚΟΙΝΩΝΙΚΗ ΕΝΣΩΜΑΤΩΣΗ. Αναρτημένη Ανακοίνωση (με δίλεπτη προφορική παρουσίαση) στο 2ο Διεθνές Συνέδριο Αθλητικών Επιστημών, Θεσσαλονίκη 25-27 Νοεμβρίου 2016, Κέντρο Δ. 2016:1-5.Abstract
Αυτή η εργασία επικεντρώνετε στον κρίσιμο ρόλο του Αθλητισμού στην προώθηση της κοινωνικής ενσωμάτωσης: τη χρήση του αθλητισμού για την αντιμετώπιση κοινωνικών ζητημάτων που σχετίζονται με την εξάλειψη κοινωνικών διακρίσεων, τη διερεύνηση τεχνικών αντιμετώπισης συγκρούσεων και την κοινωνική ένταξη. Αρχικά, στην πρώτη ενότητα, εξετάζεται ο διεθνής διάλογος, πρόσφατα αποτελέσματα ερευνών, για κοινωνικά φαινόμενα όπως ο ρατσισμός και η ξενοφοβία. Παρατηρείτε ότι οι αντιλήψεις για τους μετανάστες και πρόσφυγες (και στη χώρα μας) προκαλούν ανησυχίες για εκείνους που ασχολούνται με την πολυπολιτισμικότητα, το σεβασμό για τα ανθρώπινα δικαιώματα, τη φυλετική και την έμφυλη πολυμορφία, την κοινωνική ισότητα και ισονομία, το νόημα του έθνους, της πατρίδας κ.ά. Η διεθνής βιβλιογραφία δείχνει ότι όσο ισχυρότερο είναι το κοινωνικό κεφάλαιο των μεταναστών, τόσο περισσότερο διευκολύνεται η κοινωνική τους ένταξη. Τα τελευταία 25 χρόνια η Ελλάδα έχει μετατραπεί σε χώρα μαζικής υποδοχής μεταναστών. Ωστόσο, η αναγνώριση του γεγονότος ότι οι μετανάστες αποτελούν μόνιμη πραγματικότητα στη χώρα μας είναι πρόσφατη και ο δημόσιος διάλογος σχετικά με την κοινωνική και οικονομική τους ενσωμάτωση εξελίσσεται. Στη δεύτερη ενότητα διερευνάται η χρήση του Αθλητισμού (και της φυσικής αγωγής) ως μέσου για την καλλιέργεια μιας κουλτούρας/παιδείας ειρήνης (peace education) ή ως εργαλείου για την επίλυση συγκρούσεων, ιδιαίτερα ενόψει των αυξανόμενων διαφωνιών και συγκρούσεων που σχετίζονται με τη διαχείριση της προσφυγικής κρίσης— που πλήττει κατά 60% τις γυναίκες και τα παιδιά— για την οποία κρίση η Ευρωπαϊκή Ένωση δεν έχει ολοκληρωμένη πολιτική διαχείρισης. Εντούτοις, αναδεικνύεται ότι ο Αθλητισμός μπορεί να συμβάλλει ουσιαστικά στην κοινωνική ενσωμάτωση των μεταναστών.

Ερευνητικά δεδομένα τεκμηριώνουν ότι οι γυναίκες βρίσκονται ένα βήμα μπροστά από τους άντρες αναφορικά με κάποιες δεξιότητες, αποκαλούμενες στο παρελθόν «γυναικείες αρετές» ή«θηλυκές δεξιότητες» τις οποίες υιοθετούν όλο και περισσότεροι άνδρες επιχειρηματίες και στελέχη επιχειρήσεων σήμερα. Έρευνες που αφορούν την παραγωγικότητα δείχνουν ότι εταιρείες που απασχολούν και προωθούν γυναίκες σε ηγετικούς ρόλους εμφανίζουν, κατά μέσο όρο, περισσότερα κέρδη και μεγαλύτερη βιωσιμότητα. Με βάση τα αποτελέσματα μιας σχετικής με το ζήτημα φύλο και επιχειρηματικότητα ποιοτικής έρευνας, η μελέτη αυτή στοχεύει να αναδείξει σημαντικούς συσχετισμούς μεταξύ αθλητικής εμπειρίας και πετυχημένης επιχειρηματικότητας. Ερευνητικά στοιχεία τεκμηριώνουν ότι ένα ιστορικό αθλητικής εμπειρίας, ειδικά η συμμετοχή σε ομαδικά αθλήματα, αποτελεί χρήσιμο εργαλείο όσον αφορά στην καλλιέργεια ηγετικών δεξιοτήτων και στην ανέλιξη επιχειρηματικών δράσεων. Σχετικές έρευνες και συνεντεύξεις που πραγματοποιήθηκαν με εν ενεργεία και πρώην αθλήτριες, πρωταθλήτριες και ολυμπιονίκες πιστοποιούν ότι ο αθλητισμός προάγει δεξιότητες που είναι σημαντικές για το επιχειρείν. Θεωρείται ότι η αθλητική επιχειρηματικότητα αποτελεί ανδρικό φαινόμενο. Ωστόσο, Ελληνίδες αθλήτριες, γυμνάστριες, επιχειρηματίες και ακτιβίστριες που έχουν διαπρέψει στο αθλητικό επιχειρείν, μετά από σειρά συνεντεύξεων, μας παρέχουν πολύτιμες συμβουλές (tips-μέθοδοι-εργαλεία ενδυνάμωσης δεξιοτήτων)για επαγγελματική επιτυχία.

This paper addresses the critical issue of how wrong can water resources management go if the structure and hydrodynamic evolution of the exploited system is not well known. As a case study the River Pinios estuarine groundwater system in central Greece, is discussed. The study area has a spatial extent of about 80km2 and a typical estuarine shape. Due to the neotectonic evolution and the eustatic moves, a unique geomorphological environment and a dense hydrological network have been developed. Dominant socioeconomic activity in the region is agriculture and secondarily tourism that is focused only along a narrow strip along the coastal line and occurs only seasonally. Domestic water demands are covered by groundwater abstractions mainly from deeper wells drilled at the margins of the estuarine. Shallow wells in the alluvial sediments of the basin augment irrigation demands that are predominantly catered by surface water from the river Pinios and its tributaries, and to a minor extent several springs that emerge along the marginal fans of the basin. Due to the shallow groundwater levels, a large percentage of irrigation demands is covered by direct osmosis of water from the root zone.

Paleoceanographic proxies, such as marine micropaleontology, sedimentology and organic geochemistry havebeen performed in the sediment record of SK-3 gravity core (total length 217cm, water depth 249m) in order toprovide possible determination of late interglacial-Holocene the paleoenvironmental changes, at the southwestern margin of Cyclades plateau in the SW Aegean Sea. The sediment core exhibits two sapropels layer; thefirst one is associated with sapropel S1. The second sapropelic layer which we focus on represents anoxicconditions during the high sea-level warm event associated with sapropel S5 deposition.
Detailed pollen analyses were performed at the lower sapropelic deposits of the marine core SK-3 within theframework of a multiproxy palaeoceanographic-palaeoenvironmental study. Pollen flora is characterized byhigh arboreal pollen abundances, mainly deciduous Quercus, together with Pinus, Juniperus and otherdeciduous taxa. A transition is marked from vegetation where Mediterranean elements appear more abundanttowards mixed deciduous woodland. In the upper part of the deposits an expansion of Abies, Pinus and Fagushas been recorded. The overall vegetation pattern adds significant evidence about the terrestrialpalaeoenvironmental conditions during deposition of sapropel S5.
A study on living coccolithophores from the euphotic zone is conducted in the northeastern Aegean Sea, anarea under the direct influence of the Black Sea waters inflowing into the Aegean. A total of 53 planktonsamples from 5 stations have been collected during four sampling periods between 2011 and 2014. Highconcentrations of Emiliania huxleyi and low concentrations of oligotrophic species, such asholococcolithophores, are indicative of a direct influence of the Black Sea waters inflow on the coccolithophoreassemblages in the northeastern Aegean Sea.
Ο Διονύσιος και ο αδερφός του Ανδρέας Δεβάρης υπήρξαν σημαντικές προσωπικότητες των αρχών του 20ού αι. Ο Ανδρέας έδρασε ως ηθοποιός, ζωγράφος, μυθιστοριογράφος αλλά και αθλητής ενώ ο Διονύσιος, εκτός από ηθοποιός ήταν θεατρικός συγγραφέας, σκηνοθέτης και δημοσιογράφος. Ο Διονύσιος Δεβάρης, δραστηριοποιήθηκε συστηματικότερα στη θεατρική τέχνη: στις αρχές του 20ού αι. πρωτοεμφανίστηκε ως «μύστης» της «Νέας Σκηνής» του Κ. Χρηστομάνου, το 1909 βρέθηκε στο Παρίσι ενταγμένος στο θίασο του Raymond Duncan ερμηνεύοντας τον Ορέστη στην «Ηλέκτρα» του Σοφοκλή και την επόμενη χρονιά με τον ίδιο θίασο περίοδευσε στις Η.Π.Α., όπου και παρέμεινε για να σπουδάσει αγγλική φιλολογία. Πρωτοστάτησε στις διαδηλώσεις κατά της «Ηλέκτρας» του Hofmannsthal, η οποία παιζόταν το 1910 στη Νέα Υόρκη, θεωρώντας ότι βεβηλωνόταν το αρχαίο ελληνικό θέατρο. Επιστρέφοντας στην Ελλάδα εργάστηκε ως αρχισυντάκτης αθηναϊκών εφημερίδων και παράλληλα άρχισε να συγγράφει θεατρικά έργα. Στις αρχές της δεκαετίας του 1930 συνεργάστηκε με το Σωκράτη Καραντινό και το 1934 ίδρυσε με τον Κάρολο Κουν και το Γιάννη Τσαρούχη τη «Λαϊκή Σκηνή». Υπήρξε ένθερμος υποστηρικτής των Duncan, των Σικελιανών και της Δελφικής Ιδέας, ενώ παράλληλα μέσα από την αρθρογραφία του συχνά διατύπωνε θέσεις και κρίσεις για την αναβίωση του αρχαίου δράματος.

In this paper we attempt to map erosion and deposition zones in the island of Samos (Greece). The relief of Samos is characterized by hilly and mountainous geomorphology mantled by surface sediments and soils. The processes of erosion depends mainly on the frequency and magnitude of precipitation, surface water flow, slope characteristics, rock’s susceptibilitiy to erosion, vegetation and human impacts. The aim of this paper is to study these dynamic processes using easily updated spatial mapping processes in order to design structures to minimize erosion.

The 7 kilometers long coastline of Marathon Gulf (East Attica, Greece), has been chosen for this study, in order to classify its coastal erosion, using the Coastal Vulnerability Index (CVI) through GIS technology, since several incidents of erosion have been identified during the past decades in the area. The CVI index is used for assessing the vulnerability of a coast to an anticipated future sea-level rise. It relates geological (coastal geomorphology, historical changes of coastline’s position, coastal slopes) and oceanographic (wave height, run up and tidal range) variables in a semi-quantitative manner. We combined different kinds of datasets extracted from high resolution panchromatic aerial photographs of several time periods (1960-2010) and traced the contemporary shoreline by high accuracy surveying with Real Time Kinematic (RTK) GPS equipment. The interpretation of all shorelines required geo-statistical analysis in a Geographical Information System, in order to estimate the rate of shoreline change for a period of 53 years. Retreating rates were calculated for each section reaching the value of 0.6 m/yr. According to the produced CVI values (10.61- 39.52), it is found that 46% of the coast has very high vulnerability, 20% high vulnerability, whilst 29% have low vulnerability. The area named “Plesti” at the southern part of the study area, a large segment at the coast of Nea Makri, the northern part of Agios Panteleimonas beach and the eastern estuary of the Inois river are those with the higher risk. These conclusions are in full agreement with the field observations.
In the region of the deltaic field of Pinios River in Thessaly and under an applied geoenvironmental research, a preliminary geophysical survey was developed. In this direction, an attempt was made to develop a grid of positions-measurements that would be able to cover the whole field in order to adumbrate the general “image” of the geoelectric parameters. From the conducted bibliographic research, it seems that it is the first time that such a coordinated and extensive geophysical survey has been made in the area. In this project and in the direction of the evaluation of the geoelectric parameters of lithology present in the deltaic area, displays of the horizontal and vertical distribution of electrical resistivity are presented. This knowledge will contribute to the emergence of new data and information on the subsurface structure of the field of the deltaic plain. The geoelectrical method with the Sclumberger array was applied, for the vertical investigation of the distribution of electrical resistivity, in order to investigate the geoelectrical parameters. These arrays are best suited, as a preliminary subsurface investigation method in such geo-environments. Thirty seven soundings were developed in an almost 'normalized' grid, aiming to the greatest possible depth of investigation. Towards this direction, despite the very difficult condition of accessibility, the development of the electrode current (AB or C1C2) reached 1.100 meters, with an investigation depth >250 meters. From the sections and the constructed maps, conductive geoelectric distributions structures detected, with a resistivity ranging in 5-30 Ohm.m, in almost the whole subsurface field of deltaic plain. From this general view, seems to differentiate the coastal zone for shallow depths (<4.5 m) of investigation, the regions of the southern part of the deltaic plain with larger resistivity values for large depths (> 100 m) and the western region (Pyrgetos), with generally high values even from the shallow depths of investigation. Finally, the overall picture of the distribution of the geoelectric parameters in the field of study appears to outline potential area of the palaeogeographic development of the Pinios River delta.

part and the Karvouni mountain in the central part. The Geology of Samos consists of a metamorphic substratum, a non metamorphic unit, neogene and quaternary sediments. This island has been affected many times by natural hazards, such as forest fires, soil erosion, flash floods and gravity movements. The aim of this paper is to create an erosion risk map of Samos Island. This has been achieved by a series of separate stages, such as the creation of a database of geological, geomorphological and topographic data, extensive field observations and analyses of aerial photos and satellite images, within a GIS based platform. The final step involves the application of a functional relationship based on a probability model to input data consisting of the lithology, slope, mean altitude, and the vegetation-land use for each drainage basin to produce the final erosion risk map.
The aim of this study is to apply a state-of-the-art methodology for the estimation of environmental flows by predicting how different in-stream flows affect fish microhabitats. A habitat modelling approach was adopted to simulate and assess the ecological effects of physical aquatic habitat changes in Greek upland rivers downstream of water abstraction schemes (dams, river diversions, etc), since there is an intense debate about the construction of small hydroelectric plants in montane rivers. Two sites on the Acheloos river were chosen as study areas (Tripotamo and Mesochora upstream of the Mesochora dam), because they are located in relatively undisturbed conditions. Standard hydraulic simulation and aquatic habitat modelling was based on data surveyed along cross-sectional transects in a representative river reach. After field data collection a hydraulic model (HEC- RAS) was applied for different flows. The representative reach comprised of the habitat types and approximated proportions detected in a previous exploratory charting of hydromorphological units over a longer piece of river. Thus, a river segment for hydraulic modelling was identified in each of the study sites (segments with relatively homogeneous conditions in terms of hydrology, geomorphology, and habitats). The basic scheme of the physical habitat simulation was applied, based on a 1-dimentional hydraulic modelling, habitat evaluation with Habitat Suitability Curves (hereafter HSC) and generation of Weighted Usable Curves in function of river flow. This way, the habitat changes can be estimated for various stream flow conditions based on an indicator of habitat quantity and quality. Generic habitat suitability curves are used from Brown Trout, a relative of the native Balkan Brook Trout inhabiting local streams. In a later stage, several river flows will be integrated in the model calibration, in order to reduce the uncertainty of the model and simulate the habitat changes in terms of habitat time series within an ample range of river flows. The habitat evaluation was based on HSC; such curves are ecological models in a simple univariate format, indicating the habitat suitability of certain hydraulic conditions for a given fish species and life stage. The HSC are frequently defined by scientific studies, for the variables depth, mean velocity, substrate and cover (obtained by field observation using visual assessments by snorkelling). The habitat modelling in representative reaches enables an ecological assessment and the proposal of environmental flow regimes in the segments affected by a given water abstraction scheme. Finally, this preliminary application promotes the need for further science-based eco-hydrological approaches that are relevant to both biological quality elements and current EU policy.
The present study aims to clarify the hydrogeological regime of the phreatic aquifer, primarily its spatial distribution, through a combined interpretation of the preliminary results of an extensive geophysical research conducted in the area and of the hydrogeological data collected in parallel scientific actions by previous researchers. In the context of the geophysical research that was carried out in the region, 37 Vertical Electrical Soundings, investigating the resistivity distribution (Schlumberger array), were performed during May and October 2013. Moreover, previous periodic measurements of the groundwater level of the phreatic aquifer and hydrochemical analysis were taken into consideration. The preliminary results of the geophysical data processing indicate that the phreatic aquifer is not detected throughout the whole deltaic plain but extends mainly in the central and northern parts of the region. Most of the investigated sites showed that the hosting formation’s thickness is limited up to 10 meters, since the underlying geoelectrical formation (20-40 Ohm.m) is believed to be an impermeable formation. The literature-derived hydrogeological data also indicate that the depth of the phreatic aquifer is generally small. In particular, the groundwater monitoring showed that the water table did not exceed 4m in depth. Moreover, the hydrochemical data indicated a limited seawater intrusion, which seems to be controlled by the hydraulic head of the groundwater and the sedimentological composition of the dune system covering the coastal zone, which is also indicated by the geophysical results.
The Geopolitical analysis of a geographical System characterised by an uneven distribution of power is “the geographical method that studies, describes and predicts the attitudes and the consequences ensuing from relations between the opposing and distinct political practices for the redistribution of power as well as their ideological metaphysics, within the framework of the geographical complexes where these practices apply”.
In this paper we deal with a case scenario for the general geological setting and the morphotectonic evolution of the delta plain of Pineios River (Thessalia, Greece) and its margins. This work is based on the interpretation of geological and geomorphological data derived from (a) digitizing topographic map sheets of scale 1:5,000, (b) digital interpretation of recently acquired high spatial and spectral resolution satellite image, (c) tectonic geomorphology analysis, (d) field observations and (e) geophysical investigation. The fluvial deposits cover the largest part of the delta plain, whilst the coastal deposits crop out along the entire coastal zone. The remnants of a Pleistocene alluvial fan is observed in the western part of the delta plain and lies unconformably on Neogene formations comprised of sandstones, conglomerates and terra rossa. The alpine basement outcrops are found only at the southern and northern margins of the delta plain and include various lithologies such as crystalline limestones and metamorphic flysch (Ossa-Olympos unit), blue schists, gneisses and marbles (Ambelakia unit), metamorphic basic ophiolitic rocks and marbles (Pelagonian unit). The Neogene formations have undergone intense tectonic deformation resulting in several block rotations reaching the values of 10-30ο , towards south. The NW dipping normal fault zone located south of Omolio village strikes WSW-ENE and seems to play a significant role in the rotation of the Neogene formations. It is rather clear that the activity of this fault zone is highly related to the uplift of Ossa Mt along the southern margin of the delta plain and consequently to the development of extensional fractures (scarps) developed normally to the fault zone. These scarps are not tectonic faults and were created primarily by gravitational stresses. These structures have caused the segmentation of the uplifted block into smaller blocks, which were subsequently toppled. These large-scale toppling phenomena at the northwestern slopes of Ossa Mt have caused large gaps in the alpine basement rocks. These gaps have acted as selective surface water flow paths that have shaped impressive gorges. Pineios River found a new outlet to the Aegean Sea through the westernmost of the gorges, the Tempi gorge. It seems to have happened after the overall tectonic uplift of Olympos-Ossa-Pelion mountain range and the paleo-Pineios River flow blocking at the area south of Ossa Mt. Immediately after the aforementioned process, the area extending east of Tempi gorge began to evolve as the delta plain of Pineios River resulting in the progressive natural seaward shift of the shoreline due to the accumulation of Pineios fluvial deposits.
In this project the geological subsurface structure of the delta of the river Pinios is investigated through the contribution of geophysical soundings. In order to investigate the lithologic structure of the entire deltaic field, geophysical soundings were performed with the geoelectrical method of vertical investigation of the resistivity distribution at 37 locations. The Schlumberger array was applied, which is a reliable preliminary geophysical technique for such environments, achieving an investigation depth of > 200-250 meters. Obtaining information on the geoelectrical characteristics of the formations expected under the alluvial silt of Pinios, we have to evaluate the results of the geophysical survey. Therefore 14 “in situ” measurements of electrical resistivity were carried out in surface outcrops of Neogene sediments, cyanoschists and serpentinites. An extensive geological overview of the wider visual field was conducted, geological measurements were recorded and plotted on a digital background concerning the extensive volume of Neogene formations and alpine formations. After the processing of the geophysical soundings, geoelectrical sections were constructed in directions S-N and W-E, along with the description of their geological evaluation. From the preliminary results, it seems that the Neogene formations, with alternations of sands, marls and conglomerates occupying almost the entire space of the subsurface deltaic field, below the Holocene deposits. The alpine formations of Ossa (the southern part of the field research), seem only to be traced in the soundings near the margins, with a gentle inclination below from the post-alpine sediments and for the depths investigated (~ 200-250 meters). In the western part of the study area and more specifically the Pyrgetos sub basin, higher values of electrical resistivity (50-80 ohm) were calculated, differentiating the general concept that emerges from the rest of the study area.
The main purpose of this study was to evaluate the level of knowledge prospective teachers have about bullying, as well as their attitudes and beliefs about this issue. The majority of prospective teachers held negative attitudes about bullying. However, few indicated feeling confident or prepared to deal with the problem. Females reported greater responsibility on the part of teachers and lower levels of self-confidence than males. The greater the responsibility that student teachers placed on themselves the greater the responsibility that they placed on the school system, and the greater the concern and confidence they felt. Prospective teachers were willing to learn more about bullying.
The current study examines flow (Q) and suspended sediment concentration (SSC) variations, based on monthly snapshots, of the Pinios River (Thessaly), which is one of the larger rivers in Greece, characterized by limited flow control (<10% of its catchment). Monthly measurements (flow velocities and water samples) during the hydrological year (October 2012 to September 2013) were conducted at two stations; one before the river enters its delta (Agia Paraskevi bridge at Tempi) and one close to its mouth (Palaiopyrgos bridge). Monthly flows at Agia Paraskevi range from 2.5 m3 /s to 206.7 m3 /s and are in a good agreement with available historical data for the period 1975/76- 93/94, indicating a rather unchanged flow regime. The SSC values ranged from 3.5 mg/L to 165 mg/L at Agia Paraskevi and from 2.2 mg/L to 177 mg/L at Palaiopyrgos and, in general, follow the monthly trend of flow. The highest SSC value measured in February and April 2013 is attributed to a flood event and an upland slide, respectively.
Στα τέλη του 19ου οι παραστάσεις του αρχαίου δράματος ήταν καθιερωμένες στα αμερικανικά πανεπιστήμια. Οι καθηγητές κλασικών σπουδών αναλάμβαναν τη διδασκαλία των δραματικών κειμένων από το πρωτότυπο και επιχειρούσαν τη σκηνική αναβίωσή τους, μελετώντας παράλληλα τις αρχαιολογικές πηγές ώστε το σκηνοθετικό, σκηνογραφικό και ενδυματολογικό αποτέλεσμα να αποτυπώνει όσο το δυνατόν πιστότερα το θέατρο της αρχαιότητας. Εξέχουσα μορφή στο χώρο αυτό υπήρξε η Αμερικανίδα σκηνοθέτης Mabel Hay Barrows. Το 1899 αφού διασκεύασε σε θεατρικό έργο την «Οδύσσεια», περιπλανήθηκε στους δρόμους του Σικάγο αναζητώντας τους ηθοποιούς της στις γειτονιές των Ελλήνων μεταναστών και δημιούργησε ελληνικό θεατρικό όμιλο. Η θεατρική της δραστηριότητα έδωσε το έναυσμα σε εκατοντάδες Έλληνες μετανάστες να συστήσουν ερασιτεχνικούς θιάσους και σε άλλες αμερικανικές πολιτείες. Το άρθρο στηρίζεται σε πρωτότυπο υλικό από το πλούσιο αρχείο της Barrows στη Βιβλιοθήκη του Παν. Harvard και παρουσιάσει το σύνολο του έργου της και της προσφορά της.
This work is part of a multi-parametric research towards representation of damage scenarios in theLefkada old town. The study area lies in the most seismically active zone of the Greek territory. Mostof its buildings were built with local practices and have been designated by the European CouncilCultural Heritage Unit as representative earthquake resistant constructions. The August 14th, 2003(Mw=6.2) local earthquake produced several damage in the old town of Lefkada, with aninhomogeneous spatial distribution. In this paper we investigate the correlation of the observeddamage pattern with soil characteristics using data collected during an ambient noise survey conductedin 2007. Those were analyzed following Nakamura's HVSR methodology and soil response wasapproximated by the dominant frequencies and quasi-amplification factors of the resulted HVSRcurves. The latter were further inverted using a Monte-Carlo approach and best-fitting site specificgeotechnical models were determined. The obtained results are reasonably consistent with boreholetest data and show a remarkably good correlation with the 2003 damage distribution.
The aim of this study was to examine student teachers’ definitions of school bullying and perceived seriousness of bullying. Participants were 522 students at the Faculty of Primary Education, University of Athens, Greece. They replied to a question about the perceived seriousness of bullying and to an open question about the definition of bullying (Nikolaides, Toda, & Smith, 2002). Results showed that a considerable percentage of prospective teachers regarded bullying as a serious matter. In their definitions of bullying, they placed emphasis on physical and verbal bullying, on the bully’s intention to produce harm and on the victim’s suffering (empathy). However, some other important facets of bullying, such as duration/repetition, imbalance of power between bully and victim, the unjustified, unprovoked and group nature of bullying behavior, were much less frequently reported. Also, prospective teachers had considerable difficulty including in their definitions references to social exclusion as a specific form of bullying. Statistical significant differences in the above variables emerged as a function of gender and job experience. Results are discussed in comparison with the rather few relevant studies conducted in other countries on this issue and suggestions for the education of prospective teachers are made.
(2014). Από την αρχαία συμμετρία στη σύγχρονη αμετρία: Αρχές της φιλοσοφίας και αρχές του αθλητισμού
Οι κορυφαίες φιλοσοφικές μορφές της ελληνικής αρχαιότητας, όπως ο Σωκράτης, ο Πλάτων και ο Αριστοτέλης, επηρέασαν καθοριστικά τη μεταγενέστερη φιλοσοφία έως και τις μέρες μας, ενώ αποτελούν τους παραδειγματικούς εκφραστές της αρετολογίας της αρχαίας Ελλάδας, αλλά και τους ιδανικούς εμπνευστές αρεταϊκών ιδεωδών στο σύγχρονο κόσμο. Με τις αναλύσεις τους για τη σχέση μεταξύ ψυχής και σώματος και τον τονισμό της αξίας της σωματικής άσκησης των νέων οι φιλόσοφοι αυτοί προσέδωσαν στον αρχαίο ελληνικό αθλητισμό σημασία πρωτόγνωρη για τα δεδομένα της εποχής. Ο αρχαίος αθλητής ήταν μέτοχος ενός πολιτισμού που εξέφραζε το σύμμετρον, το οποίο δεν ήταν παρά η αποτύπωση των φυσικών γνωρισμάτων του ελληνικού λαού. Η επιθυμητή αρμονία της ψυχής και του σώματος, που συνιστά το ιδεώδες της καλοκἀγαθίας, αποτελεί κεντρικό στοιχείο του αθηναϊκού πολιτισμού.
Η φιλοσοφική προσέγγιση του σώματος δείχνει ότι οι εποχές και οι λαοί νοηματοδότησαν διαφορετικά τη σωματικότητα. Έτσι, ενώ στην κλασική αρχαιότητα η ψυχοσωματική ανάπτυξη εκλαμβάνεται ισομερής, αντίθετα στη βυζαντινή περίοδο η σωματικότητα εκλαμβάνεται πολύ υποδεέστερα απέναντι στην πνευματικότητα. Στις μεταβιομηχανικές κοινωνίες, όμως, έως και σήμερα κυριαρχεί η εμμονή στην επιδίωξη του κέρδους. Στο χώρο ειδικότερα του αθλητισμού, και σε αντίθεση με τον αρχαίο αθλητή, ο σύγχρονος αθλητής βάλλεται από ένα ιδεολογικά κερδοκεντρικό σύστημα, το οποίο επικροτεί το άμετρο, την υπερβολή, την βιομηχανοποίηση της επίδοσης και την εργαλειοποίηση του ανθρώπινου σώματος. Η αποσαφήνιση της αντιιδεαλιστικής και αντισυστημικής σχέσης της φιλοσοφίας με τη σωματικότητα του αθλητισμού υπόκειται στην ανάγκη για την όρθωση και την επεξεργασία μιας σύγχρονης φιλοσοφικής ανθρωπολογίας. Εάν δεν απαντηθεί εκ νέου το ερώτημα «τι είναι άνθρωπος», τότε τα μεταβιομηχανικά υλιστικά πρότυπα, καθώς μάλιστα διογκώνονται μέσα από την επικράτηση της σύγχρονης οικονομικής παγκοσμιοποίησης, παραμένουν κυρίαρχα και επιβεβλημένα. Παράλληλα, η ευγενής άμιλλα, αποτελώντας τον πυρήνα του αθλητικού ιδεώδους, λειτουργεί ως καίριο στοιχείο ηθικής αγωγής, και, κυρίως, αντιστέκεται στην πλεονεξία και στη σύγχρονη αμετρία.
(2014). Η έννοια του αγώνα και το αγωνιστικό ιδεώδες των Ελλήνων
Κατά την περίοδο της ελληνικής αρχαιότητας η ιστορία ενώνεται με το μύθο, ο συμβολισμός με την παράδοση και η εγκράτεια με την έμπνευση, σε ένα φάσμα εξαιρετικά ευρύ.Πίσω από τις εκδηλώσεις της ζωής κρύβεται, ωστόσο, η ψυχή του λαού, η οποία ως θεμελιώδη χαρακτηριστικά έχει την αγάπη προς το ωραίο, την ελευθερία και τον αγώνα. Το ελληνικό πνεύμα με τη διαρκή αγωνιστικότητα δημιούργησε τον πολιτισμό του ηθικά και αισθητικά ωραίου, καθώς και τον πολιτισμό της ελευθερίας, τις δύο μορφές πολιτισμού που χαρακτηρίζουν και την αρχαία και τη μεσαιωνική και τη σύγχρονη Ελλάδα. Από τότε που εμφανίζεται για πρώτη φορά ο Έλληνας μέχρι σήμερα διαρκώς αγωνίζεται, πότε κατά τον πόλεμο και πότε κατά την ειρήνη. Αγωνίζεται ως άτομο, αλλά και ως κοινωνικό και πολιτικό σύνολο, ως πόλη της αρχαιότητας, αλλά και ως κράτος μεσαιωνικό ή νεότερο, ως ομάδα και φυλή, ως οικογένεια και γένος, ως λαός και έθνος. Δεν είναι τυχαίο, εξάλλου, ότι ως ‘έθνος’ οργανώθηκε μέσα στη φάση αντιπαλότητας των διαιρεμένων πόλεων που πολεμούσαν μεταξύ τους. Οι προσπάθειες, οι μάχες και οι αγώνες είναι, κατά κάποιο τρόπο, το πεπρωμένο του Έλληνα στη μακρινή του πορεία. Ειδικότερα ο όρος «αγών», έχοντας τόση ιστορία πίσω του όση και η ίδια η Ελλάδα, αποκαλύπτει το αγωνιστικό ιδεώδες της ελληνικής ψυχής.
Ο έμφυτος ατομισμός του Έλληνα, αντίθετα με ό,τι ίσχυσε για την υποτακτική προσωπικότητα του ανθρώπου της Ανατολής, τον βοήθησε ν’ ανακαλύψει τη μορφή του φορέα τουαγώνα, δηλαδή τον ένα άνθρωπο. Από τη στιγμή της εισόδου του στην ιστορική κονίστρα, είτε αυτή επρόκειτο για την αρχαία παλαίστρα, είτε για κάθε πεδίο δράσης όπου εκδηλώνεται ανταγωνισμός για την επικράτηση, ο άνθρωπος σταμάτησε, πλέον, να συνιστά μια αφανή μονάδα, και έγινε ελεύθερη οντότητα, συνιστώντας οργανικό µέρος του πολιτικού και κοινωνικού συνόλου. Ο ανθρωπολογικός ατομισμός των Ελλήνων, σε συνδυασμό με την κοινωνικότητά τους, γέννησε, επομένως, τον αγώνα, ως αποτέλεσμα της σύνθεσης του ατομικού και του κοινωνικού στοιχείου της ελληνικής ψυχής. Το αγωνιστικό πνεύμα αφήνει τα ίχνη του σε όλες τις πτυχές της ιστορικής ζωής, όπως δηλώνει και η διαμόρφωση από τους Έλληνες των αθλητικών αγώνων, οι οποίοι υπογραμμίζουν την καθολικότητα του αγωνιστικού φαινομένου της ελληνικής ζωής.
Το υγιές πνεύμα της άμιλλας και του αγώνα αποτέλεσε διαρκές κίνητρο νέας δημιουργίας, ήταν δηλαδή κίνητρο παιδείας. Ο ελληνικός πολιτισμός συνίσταται, εν τέλει, σε µία ισορροπία αντιθέσεων, που, όμως, δεν αποσυντίθεται όπως ίσως θα αναμενόταν, αλλ’ αντιθέτως, αυτοσυντηρείται και εξελίσσεται. Ο σύγχρονος αγώνας συνεχίζεται στα νέα πεδία της ιστορικής δράσης του ελληνισμού. Κι αν το αρχαίο ελληνικό θαύμα ως ιστορικό φαινόμενο έμεινε ανεπανάληπτο, ωστόσο ο αγώνας δεν διακόπηκε, αλλά έλαβε άλλες μορφές, τις οποίες υπαγορεύουν οι ανάγκες των νέων καιρών. Ο ουσιαστικότερος αγώνας, πάντως, σήμερα είναι ο ανθρωπιστικός, ο οποίος δίνει έμφαση στην αξία του ανθρώπου, υποστηρίζοντας πως αληθινό είναι μόνο ό,τι προάγει την ανθρώπινη ζωή και οδηγεί τον άνθρωπο στην ολοκλήρωσή του. ***

The great narrative is an invitation for the discovery of a problem, as Jerome Bruner stated. Ifwe select gifted writers and poets and study their work as well as their narratives about loneli-ness during their childhood years (and not only then), we will uncover many faces of loneli-ness and solitude – perhaps the most painful and the most beneficial ones. We selected asmall number of writers from Greece and other countries, in the childhood of whom loneli-ness and solitude had played a significant part and seemed to have determined their lives andwork. By focusing on specific aspects of their lives and work, we discuss how lonelinessmeets with the gift of narrative from the early years of life.
(2014). Η σχέση της φιλοσοφίας και του αθλητισμού από την αρχαιότητα έως τον σύγχρονο κόσμο
Ο αθλητικός αγώνας αναπτύχθηκε εντός της φυσικής, ιδεολογικής και κοινωνικής ατμόσφαιρας του αρχαίου ελληνικού πολιτισμού. Φιλοσοφικά, η ιδεολογία που καλλιεργείται στους πανελλήνιους αθλητικούς αγώνες αποτελεί την αντανάκλαση του βαθύτερου υπόβαθρου με το οποίο ταυτίζεται ο κλασικός πολιτισμός, δηλαδή της συνύπαρξης, και μάλιστα της ισορροπημένης συνύπαρξης, των αντιθέτων. Την περίοδο αυτή ήταν ισχυρή η οντολογική σχέση μεταξύ ψυχής και σώματος. Το κάλλος, το ωραίο, το ιδεώδες, ο άθλος, το κλέος, η ηθική του αγώνα και του αθλητή ως προτύπου, η αισθητική και η αξιολογία τους είναι έννοιες φιλοσοφικές, έννοιες που ανήκουν στη σφαίρα και στη δικαιοδοσία της φιλοσοφίας.
Το ενδιαφέρον για τη σωματική υπόσταση του ανθρώπου, ως σημαντικού μέρους της διττής ανθρώπινης υπόστασης, δεν έπαψε ποτέ να απασχολεί τους διανοητές και τις κοινωνίες, μιας και ο αθλητισμός αντιμετωπίστηκε ως τμήμα της εκάστοτε κοινωνικής ζωής. Η στάση προς το φυσικό σώμα, είτε πρόκειται για στάση σεβασμού είτε για στάση απαξίωσης, έχει γνωρίσματα φιλοσοφικά και ιδεολογικά. Οι μεταβιομηχανικές ιδίως κοινωνίες, έως και τις μέρες μας, χαρακτηρίζονται από τον βιομηχανοποιημένο τρόπο ζωής και τον εκμηχανισμένο τρόπο παραγωγής, απόρροια ενός εκμηχανισμένου πολιτισμού. Επικρατεί ο οικονομικός υλισμός, και η απολυτοποίηση του κέρδους και οτιδήποτε υλιστικού, στο οποίο και εντάσσεται το φυσικό ανθρώπινο σώμα, το οποίο στην πραγματικότητα καθίσταται θύμα αυτής της ισοπεδωτικής και υπολανθάνουσας λογικής. ανθρώπου. Η ανθρωπολογική έννοια του αθλητισμού μπορεί να προσδιορίσει ένα όριο ασφαλείας, το οποίο θα προφυλάσσει το αθλητικό και γενικότερα το ανθρώπινο σώμα από την υπερέκθεση και την υπερκατανάλωση. Διαφαίνεται, επομένως, η ανάγκη της «φιλοσοφικής ανθρωπολογίας», της σύλληψης δηλαδή της ουσίας του ανθρώπου, αλλά και της πολιτικής φιλοσοφίας του σώματος.
The aim of this study was to examine student teachers’ knowledge and attitudes toward school bullying. Participants were 676 students at the Faculty of Primary Education, University of Athens, Greece. They replied to a question about the perceived seriousness of bullying (Nikolaides, Toda, & Smith, 2002), and completed the Teachers’ Attitudes About Bullying Questionnaire (Beran, 2005). Principal components analysis confirmed the five-component structure of the questionnaire. Results showed that a considerable percentage of prospective teachers regarded bullying as a serious matter and wanted to learn more about this issue during their studies. Also, they expressed high personal commitment and system commitment to dealing with bullying. Although they are not satisfied with their education on bullying, they exhibit at least moderate confidence in coping with it. Results are discussed in comparison with the few relevant studies conducted in other countries on this issue and in relation to the developmental characteristics of emerging adults.
(2014). Το όραμα του υπερανθρώπου και το μετανθρώπινο μέλλον: Σχεδιάσματα, επιτεύγματα, ουτοπίες
Η ιδέα του υπερανθρώπου εμφανίζεται πρώτη φορά στο στοχασμό του Friedrich Nietzsche (DerÜbermensch), ο οποίος υποστηρίζει πως ο άνθρωπος με μια ηρωϊκή προσπάθεια θέλησης και φαντασίας θα μπορούσε να ξεφύγει από την αθλιότητα και να δημιουργήσει ένα ανώτατο ον, τον υπεράνθρωπο. Ο Νιτσεϊκός υπεράνθρωπος, ωστόσο, ουδεμία σχέση έχει με τον σύγχρονο υπεράνθρωπο, καθώς ο πρώτος είναι ο ιεροφάντης μιας νέας προστακτικής ηθικής (Pearson, 2007), ενώ ο δεύτερος ένα αφύσικο κατασκεύασμα της τεχνολογίας, ένας Superman. Ένας τέτοιος άνθρωπος, όμως, υπερβαίνει τα φυσικά ανθρώπινα όρια. Το όραμά του φαντάζει ως μια τεχνοουτοπική φαντασίωση. Μπορεί, άραγε να γίνει αληθινό; Σε μια μεταβιομηχανική εποχή, πάντως, η δόξα θα ανήκει, πλέον, στην επανάσταση της βιοεπιστήμης που σημειώθηκε στις αρχές του αιώνα (Lawton, 2006). Επιμήκυνση της μακροβιότητας, διατήρηση της νεότητας, ενώ αρκετοί άνθρωποι έχουν υποστεί βιολογικές παρεμβάσεις και «αναβαθμίσεις» που τους προσφέρουν υπεράνθρωπες νοητικές ικανότητες ή σωματικές επιδόσεις. Ραγδαίες είναι, επίσης, και οι εξελίξεις στις συσκευές που διασυνδέονται με τον εγκέφαλο, ενισχύοντας τις λειτουργίες του με υπερφυσικές δυνάμεις (Sandel, 2011), και για την πλήρη κατανόηση του ανθρώπινου γονιδιώματος (Lewontin, 2000, 2002). Οι υπάρχουσες τεχνολογίες, ωστόσο, δεν αναπτύχθηκαν ειδικά για να επιτρέψουν στους υγιείς ανθρώπους να ξεπερνούν τα όριά τους, αλλά για να θεραπεύσουν ασθένειες, επιτελώντας κοινωνικό έργο. Διαθέτουν, επομένως, αρχικά την ηθική αποδοχή, και στο τέλος καταλήγουν να χρησιμοποιούνται από όποιον επιθυμεί να αποκτήσει πλεονέκτημα έναντι των άλλων (Lawton, 2006, Γογγάκη, 2013).
Οι παραπάνω εξελίξεις αντιμετωπίζονται με δύο αντιμαχόμενες τάσεις. Οι υπέρμαχοι ή μετανθρωπιστές, όπως ο βιοηθικολόγος James Hughes (2014), προβλέπουν τη δημιουργία μιας «συλλογικής νοημοσύνης» (The Hive Mind) που συνδυάζει τη νοημοσύνη του ανθρώπινου είδους σε έναν τεχνολογικό εγκέφαλο (Estulin, 2009, 2014). Γενικά το φιλοσοφικό ρεύμα που συνδέεται με τους όρους posthumanism, metahumanism ή transhumanism υποστηρίζει την εξέλιξη του ανθρώπου μέσα από την επίδραση της γενετικής, της τεχνολογίας και των εμφυτευμάτων. Σύμφωνα με τη θεωρία του μετανθρωπισμού, ο συνήθης άνθρωπος αποτελεί απλά ένα «στάδιο ανάπτυξης» της συνολικής ανθρώπινης οντότητας. Οι αντίμαχοι αυτών των τεχνολογιών παρομοιάζουν ένα τέτοιο ενδεχόμενο με τον BraveNewWorld του Aldous Huxley (1931), ένα μέλλον δηλαδή όπου οι κάτοικοι μέσω τεχνολογικών αναβαθμίσεων ζουν ζωές επίπεδες και άδειες, μέσα στην απόλυτη ομοιομορφία. Ο βιοηθικολόγος George Annas επισημαίνει ότι οι κίνδυνοι από τη γενετική τροποποίηση είναι ακόμη μεγαλύτεροι, ώστε θα ήταν καλύτερα να τεθεί από τώρα ένα τέλος σε όλη αυτή τη διαδικασία, προτείνοντας μια παγκόσμια συμφωνία που θα καθιστά τη γενετική τροποποίηση έγκλημα κατά της ανθρωπότητας.
Το γενετικό μέλλον του ανθρώπινου είδους και η ανθρώπινη αναβάθμιση μπορεί να υπόσχονται την ελευθερία, ενδέχεται όμως να προκαλέσουν πρωτόγνωρες δυσκολίες (Fukuyama, 2002, Kuhse-Singer, 1999, Machery, 2008); Το κυριότερο ερώτημα, όμως, είναι: ως πού, θέλει να φτάσει ο άνθρωπος; Μήπως, θέλοντας να τα κατακτήσει όλα, είναι καταδικασμένος, τελικά σε μια σκλαβιά επιθυμιών, που μοιάζει με πιθάρι χωρίς πάτο; Η συζήτηση σχετικά με τις δυνατότητες των μελλοντικών τεχνολογιών είναι σε εξέλιξη. Οι μετανθρωπιστές αφαιρούν, ωστόσο, το ευρύτερο πλαίσιο, τον πολιτισμό, την εμπειρία και τα σώματα από το όραμά τους. Χωρίς, όμως, ευρύτερο πλαίσιο, πολιτισμό, εμπειρία και σώματα, τι απομένει στη συνείδηση; Στην πραγματικότητα η επιθυμία να ‘μεταφέρεις’ ή να κάνεις ‘μεταφορά μυαλού’ υλοποιείται συνεχώς από παραγωγικά ανθρώπινα όντα. Ίσως είναι καλύτερο να προσπαθεί κανείς να είναι παραγωγικός σ’ αυτή τη ζωή, παρά να ονειρεύεται ότι θα είναι παραγωγικός στην επόμενη ζωή.
The seismic history of the centre of Athens may be revealed through the response of its classical andneo-classical columns to ambient noise and earthquake shaking. Detailed ambient vibration surveys in two casesare presented: a) the two choragic columns on the south slope of the Acropolis, above the Monument ofThrasyllos, constructed in the late classical-early Hellenistic era (3rd–1st century B.C.), with an original designand a high constructive quality (13 April – 10 May 2011) b) the statue of Apollo (mid-19th century), on the rightside of the Academy of Athens building prostyle, mounted on a column in the Ionian rhythm (5-13 March 2008).In the first (Acropolis) case, ambient noise measurements were performed with seven digital 3-componentseismographs at the top and the base of each column, as well as at three nearby reference sites. In addition,forced vibration tests at the top of each column were also conducted. In the second (Academy) case, fiveinstruments of the same type were installed at the base of the column, the base of the statue, with reference sitesat the two corners of the Academy building and the garden at the back side of the building. For both cases, the response spectra and amplitude ratios were computed, providing information on the soil-column interaction, as well as the characteristic frequencies of spectral ratios peaks.

Hitzel F. 14th International Congress of Turkish Art. 2013:97-103.Abstract
Le présent article, qui s’appuie essentiellement sur une documentation photographique non publiée, étudie le fonds photographique de la Société de Géographie de Paris (SGP) analysant des clichés datant de la fin du XIXe siècle et du début du XXe siècle. A une époque où la photographie sert de documentation et de moyen d’éducation, la SGP a inauguré une politique de collecte de photographies. Conservé actuellement à la BnF, son fonds photographique comprend des clichés commerciaux, que les voyageurs achétaient au cours de leurs pérégrinations, des clichés pris lors des missions scientifiques ainsi que des clichés d’amateurs, que les membres de SGP lui offraient. Associant la qualité esthétique à la valeur documentaire et historique, le fonds photographique de la SGP, qui perpétue souvent l’image stéréotypée de l’Orient, représente les différents aspects de l’Empire ottoman permettant parfois la reconstitution des étapes des pérégrinations des voyageurs. De plus, le fonds photographique, qui est caractérisé par une variété thématique, est révélateur de l’intérêt de l’Empire ottoman pour la gestion de son image dans le cadre de la propagande politique. Finalement, le fonds photographique du SGP constitue un exemple caractéristique du rôle et de la réception de la photographie comme documentation.
Following the French Language Teachers Post-graduate Program of the Hellenic Open University a considerable number of dissertations has been completed thus involving an equivalent number of supervisors. The dissimilarities of the completed dissertations seem to depend on the students' abilities and the tactics of the supervisors. This announcement aims at investigating into the established practices and process followed by both, supervisors and students, during the writing of the dissertation. The investigation was based on questionnaires and interviews addressed to students, graduates and supervisors. The results of this research are focused on the points that have received the strongest criticism by both, supervisors and students. These points divert from the mediation and evolutionary guidance during the dissertation writing (Feuerstein, Vygotsky, Bruner).
The purpose of this paper is to assess the vulnerability to ground shaking of the building stock in the old town of Lefkada Island (Ionian Sea, W. Greece). The study area lies in the most seismically active zone of Greece region. Most of its buildings were built with local practices and have been designated by the European Council Cultural Heritage Unit as representative earthquake resistant constructions. Within the context of this research we conducted an in-situ survey, of all buildings in the old town. In addition, the 2001 buildings census catalogue elaborated by the National Statistical Service of Greece was employed, as well as the damage inspection data following the 2003 earthquake. The collected data, after a detailed processing, were projected as they would have been prior to the August, 14, 2003, Mw=6.2 Lefkada earthquake. Each building was indexed by an EMS-98 vulnerability class. All results were combined in an ArcGIS scheme in order to compute the lateral vulnerability distribution and to compare it with the 14/8/2003 earthquake effects.
(2013). Η ανάγκη διαμόρφωσης μιας νέας ηθικής του Ολυμπισμού και του αθλητισμού.
Ο αθλητισμός, αποτελώντας μιὰ πολιτιστικὴ εκδήλωση, δεν είναι αποκομμένη απὸ το κοινωνικο και πολιτικὸ περιβάλλον, εντὸς του οποίου λαμβάνει υπόσταση. Οι αθλητὲς και οι παράγοντες του αθλητισμού, ως άνθρωποι και ως πολίτες, επηρεάζονται άμεσα απὸ το σύνολο των αξιών, οι οποίες διέπουν τη ζωὴ της πολιτικής κοινωνίας. Ο αθλητισμός, όπως και κάθε άλλη επιμέρους έκφανση της πολιτιστικής δραστηριότητας, έχει βεβαίως τις δικές του αξίες, καθὼς και όλες εκείνες τις αρετές που περιέχονται σε μια τέτοιας φύσεως ειρηνικὴ εκδήλωση. Όμως όπως και στην κοινωνία έτσι και στο χώρο του αθλητισμού, ενώ προβάλλεται η δικαιοσύνη, η εντιμότητα και η ισότητα, ωστόσο η καθημερινὴ πρακτικὴ βεβαιώνει την διάπραξη αδικιών και παρανομιών. Αντίστοιχα, ο αθλητισμὸς έγινε πρωταθλητισμός, ενώ η ευγενής άμιλλα έγινε ανόσιος ανταγωνισμός, ο οποίος συχνά χρησιμοποιεί κάθε άνομο μέσο, προκειμένου να επιτύχει τη νίκη.
Οι πράξεις που φθείρουν το πνεύμα του αθλητισμού συνδέονται, επομένως, με τη δομή της παγκόσμιας κοινωνίας, η οποία στο όνομα του οικονομικού συμφέροντος ανέχεται τη νόθευση αρχών διαχρονικού κύρους. Η υπονόμευση, όμως, του αθλητικού πνεύματος έχει σχέση και με την ίδια τη φύση του ανθρώπου, καθώς αυτός αναλώνεται για την κατάκτηση μιας θέσης στην κοινωνική ιεραρχία. Εν τέλει, ο θρίαμβος της αγοραίας ηθικής και λογικής που χαρακτηρίζει συνολικά τη δυτική κοινωνία, αντανακλάται και στον αθλητισμό. Είναι αναγκαία, επομένως, η αναζήτηση μιας νέας αθλητικής φιλοσοφίας, που σε συνδυασμό με την απομυθοποίηση των επίπλαστων ειδώλων, αντί για την πρωτιά θα εστιάζει στο καλύτερο που μπορεί να προσφέρει ένας νέος, βασισμένος στη φυσική του υπόσταση. Η ουσιαστική μετατροπή της ποιότητας του αθλητισμού είναι εφικτή, υπό την προϋπόθεση της πλήρους ανατροπής του υπάρχοντος οικονομικού και πολιτικού συστήματος και του ρόλου της παιδείας.
(2013). Η εθνική πολιτική στον αθλητισμό και η παγκόσμια πολιτισμική κρίση.
Η παγκόσμια οικονομική και πολιτισμική κρίση επηρεάζει, όπως είναι φυσικό, και τον αθλητισμό, ως ανθρωπολογική δραστηριότητα. Η αντιμετώπιση του αθλητισμού ως προσοδοφόρου επαγγέλματος, αντί για χώρου παιχνιδιού και ευχαρίστησης, μετατρέπει τον αθλητή από άνθρωπο σε εμπόρευμα και τον αθλητισμό από ελεύθερη επιλογή σε επαγγελματικό καθήκον. Η πρακτική της επίσημης πολιτείας αποκαλύπτει την υποστήριξή της στον αθλητισμό κορυφής, από τον οποίο αναμένει και επιδιώκει εθνικά οφέλη. Έτσι, «επενδύει» στον ανταγωνιστικό αθλητισμό, σαν να επρόκειτο για μετοχή του χρηματιστηρίου, προκειμένου να μεταφράσει τις νίκες σε κατάλληλη προπαγάνδα για την δήθεν επιτυχή πολιτική της. Για το λόγο αυτό συνάπτει ένα είδος συμβολαίου με τον επίδοξο αθλητή ή τον προπονητή του, βρίσκοντας ως καίριο σύμμαχο τα μέσα μαζικής επικοινωνίας, τα οποία είναι έτοιμα να συμβάλλουν στη μεγιστοποίηση του στόχου, διογκώνοντας το μέγεθος της επιτυχίας.
Στον ελληνικό αθλητισμό ειδικότερα, από την εποχή της Χούντας έως σήμερα, ο τρόπος με τον οποίο το πολιτικό σύστημα δείχνει να αντιλαμβάνεται την αξία της αθλητικής επιτυχίας, έχει λειτουργήσει κάπως σαν κληρονομιά. Πέρα, όμως, από τις ελάχιστες περιπτώσεις πρωταθλητών, ο αθλητισμός αποτελεί στην Ελλάδα ένα άδειο τοπίο, ενώ και ο αθλητισμός στο σχολείο θυμίζει μάλλον τεχνικές σε αυλές του Μεσαίωνα, παρά παιχνίδι και φυσική άσκηση για τους νέους. Την ίδια στιγμή στην παγκόσμια σκηνή, όπου ο άνθρωπος καλείται σήμερα να δράσει, κυριαρχεί η διαφθορά, η ωμότητα, η κάθε είδους βία και ο κυνισμός. Λίγο-πολύ ο παγκόσμιος αθλητισμός απηχεί ένα πολιτικό και κοινωνικό σύστημα που διαθέτει ανάλογα χαρακτηριστικά. Η πολιτεία, όμως, παρά τα προβλήματα, θα πρέπει να συνειδητοποιήσει την αξία του αθλητισμού, για όλους, και ειδικά για τους νέους κατά την περίοδο της σχολικής εκπαίδευσης. Δια του αθλητισμού μπορεί να αναπτύξει τις αρχές που οφείλει να τηρήσει ο αθλητής για να μη χάσει το όριο της αρετής του. Εξάλλου, εκτός από την αξιολόγηση του αθλητισμού, μπορεί να προβεί και στην αναζήτηση εκείνων των ηθικών χαρακτηριστικών, που η ίδια η πολιτεία θεωρεί αδιαπραγμάτευτα για τη διασφάλιση της ποιότητάς του.
(2013). Η ηθική του σύγχρονου αθλητισμού υπό το πρίσμα της κρίσης των αξιών.
Η τοπική και η παγκόσμια κοινότητα αντιμετωπίζoυν σήμερα μια βαθύτατη κρίση, η οποία ουσιαστικά εδράζεται στην κακοποίηση και την αλλοτρίωση των ηθικών αξιών. Το εγωκεντρικό και ωφελιμιστικό πνεύμα που επικρατεί σήμερα σε κάθε έκφανση της ζωής υπεισήλθε και μόλυνε και το πνεύμα του αθλητισμού - το οποίο στην αυθεντική του μορφή είναι πνεύμα άμιλλας και υπέρβασης των ανθρώπινων δυνατοτήτων. Έτσι, υπάρχει μια ανισοκρατία στην άμιλλα, ενώ η θήρα του αθέμιτου ανταγωνισμού και του κέρδους έφθειραν και ακόμη φθείρουν το πνεύμα του αθλητισμού. Η τάση, αναίρεσης, ωστόσο, των αρχών του καλώς αγωνίζεσθαι, διαμορφώνεται από την παρεχόμενη προς τους νέους «παιδεία», που υποθάλπει τον γρήγορο και εύκολο πλουτισμό ή την με οποιοδήποτε τίμημα προβολή των ανθρώπων. Το αποτέλεσμα είναι, αντί για την, μετά από δίκαιο αγώνα, ηθική ανύψωση του αθλούμενου, και αντί για τον καθαρό αγώνα εντός του σταδίου, να επιβραβεύεται ο δόλος, τα σκοτεινά παρασκήνια και η συνολική αλλοτρίωση της ιδέας του αθλητισμού ως αξίας.
Η υποκειμενική αποτίμηση της αθλητικής νίκης έχει αντικαταστήσει το φιλοσοφικό της περιεχόμενο με την οικονομική της αξία. Η αθλητική νίκη υπό το κριτήριο αυτό θεωρείται ως καρπός της κυριαρχίας της υποκειμενικότητας, κυριαρχία την οποία η αυθεντική φιλοσοφική σκέψη οφείλει να υπερβεί. Η οπτική γωνία δεν μπορεί να είναι η βούληση για δύναμη, αλλά η άρνηση της ιδιοτέλειας, καθώς επίσης και η βούληση για άρση πάσης μορφής δύναμης που οδηγεί σε πλάσματα κυριαρχίας, άρα στην καταπίεση της ίδιας της ζωής. Η κακοποίηση των ηθικών αξιών φαίνεται πως οφείλεται, επομένως, κυρίως στην εναλλαγή των τιμών έντασης των αξιών αυτών, οι οποίες, ωστόσο, πάντα προσφέρουν τη δυνατότητα να αξιολογηθούν από τις επερχόμενες γενιές περισσότερο αυθεντικά από ό,τι ισχύει σήμερα.
The objective of the present paper is to present an alternative method of foreign language learning, the tandem. We try to define it, we refer to the way that it can work and how it can be applied in language learning. Next, we are focusing our interest on the electronic tandem and analyze certain digital tools that are used in implementing this particular process. The tools are categorized by the type of communication (synchronous or asynchronous) that they achieve and their presentation includes information about what these tools are, how they are used and whether their use is easy, the way they can help the participants throughout the process, but also the problems associated with their use. More specifically, we refer to the chat, the videoconference and the virtual worlds which are considered tools of synchronous communication. We also analyze the e mail and the blog, which are tools of asynchronous communication. Finally, we refer to the use of the social media in the tandem process, which are considered tools that combine synchronous with asynchronous communication Our final objective is to inform the teachers and students of the foreign languages about the possibilities that the tandem offers and to motivate educational institutions to incorporate the particular method in their educational programs.

Policy makers consider that sport contributes to a wide range of ideals such as intercultural understanding, reconciliation, social integration. Grassroots programmes involving tens of thousands participants around the globe from visionaries, educators, civic acitivists, volunteers, etc. are using sport to tackle the most pressing problems of the developing world—from AIDS in Africa to violence in Rio and Haiti. Is this the vision of salvation through sport too grandiose? Can such projects make a lasting difference? Remarkable results have been documented by many NGOs that have been using sport as a tool to promote reconciliation and respect for ethnic diversity. Sport is considered a vital space, especially in light of today’s xenophobic worldviews. (See proceedings)

Morphological abnormalities of recent and fossil benthic foraminiferal tests may be caused by environmental stress resulting from anthropogenic pollution and/or natural effects. In the present paper we document and describe morphological abnormalities of Ammonia tepida and some additional foraminiferal species from Holocene sedimentary successions of the Aegean Sea (Alykes Kitros and Vravron Attica). The abnormality types are manifested largely by siamese twins, whereas distorted chamber arrangement, overdeveloped or protruding chambers and the presence of multiple apertures have also been observed. Our observations on the distribution of abnormal tests in comparison to the characters of the accompanying fauna suggest that malformation was caused mainly by rapid and intense salinity fluctuations.

La présente étude traite de l’adaptation cinématographique d’Angélique marquise des Anges d’Anne et Serge Golon, qui a connu un grand succès en librairie. Classé comme roman populaire, le roman des Golon, qui a souvent été ignoré par la critique, est une oeuvre historiquement bien documentée. Adressée à un public essentiellement féminin, Angélique marquise des Anges, dont le casting réunissait des auteurs célébres, a été à l’origine de cinq films réalisés par Bernard Borderie, qui ont connu un succès commercial important. Après une courte présentation de l’oeuvre littéraire, nous analysons la personnalité et l’image de Louis XIV et de sa cour dans les cinq films. Vu l’étendue du roman fleuve, le scénariste et le producteur ont été obligés de rendre partiellement le caractère des personnages historiques ou même de les supprimer dans l’adaptation cinématographique. De plus, ils ont enlevé des descriptions et des passages importants réduisant ainsi les références chronologiques. En outre, quoique dans les romans des Golon, l’image de la cour de Louis XIV soient représentée de manière réaliste, dans les films de Borderie, qui se focalisent sur les aventures amoureuses de l’héroine, malgré l’utilisation d’un décor naturel, elle n’a pas été rendue de manière convaincante. Révélatrice des rapports complexes entre la littérature et le cinéma, l’adaptation cinématographique de la série d’Angélique, était, à l’exception du premier film de Borderie, une adaptation libre du roman, ce qui n’a pas nuit à son grand succès commercial
Active faulting usually produces a dynamic and continuously evolving morphology along the fault trace but also at the adjacent area. The morphologic discontinuities which are often created due to the relative displacement of the fault walls, host quite a few structures that are vulnerable to erosion and surface alterations. The technology of Light Detection and Range ground based instruments is a valuable tool used for topographic micro-analysis of recently exposed fault surfaces and consequently for detailed mapping and structural measuring. In this paper we suggest a methodology for monitoring the stability of an almost vertical active fault surface with lots of tectonic structures on it but also with a large amount of brittle debris material lying on top of it. This methodology was based on several laser scans with a ground LiDaR and the detailed mapping of weak zones along the fault surface led to the construction of a rock-fall hazard model.
Detailed quantitative analyses of calcareous nannofossils/coccolithophores performed on the deep sea deposits of the north eastern Mediterranean Sea; two gravity core from North Aegean Sea (SL 152) and south Cretan continental margin (HCMR 2/22), with a focus on the regional expression of sapropel S1 deposition. In both sites, higher values of Florisphaera profunda, Helicosphaera spp., Braarudosphaera bigelowii and the concomitant increase of stratification S index, within sapropel intervals can be interpreted as the result of elevated marine production and enhanced inflow of fresh water input during the S1 period. A series of cooling events detected within the S1 depositional interval, may be linked to outbursts of cold northerly air masses and relevant pulses in the deep-intermediate water ventilation that caused the temporary cessation of S1 deposition between 7.8-7.5 ka uncal. BP in North Aegean and 8.1-7.8 ka uncal. BP at the south Cretan margin. During this interval the peak of Braarudosphaera bigelowii, the decrease in abundance of Florisphaera profunda, Helicosphaera spp., Rhabdosphaera spp. and a general increase in NPP are related to a shoaling of the nutricline and higher production in the surface layer.
