Galanaki E, Arnett JJ, Amanaki E. Achieving adult status in Greece. Journal of Youth Studies. Submitted.Abstract
The attainment of adult status in Greece is a neglected research issue. Sociodemographic changes and the severity and long duration of the Global Recession in this country (2008-2018) are expected to contribute to the delayed entry to adulthood, especially among university students. In this study, conducted in 2015, 814 university students (ages 18-25; M = 19.9) provided information on subjective adult status (per se and with significant others), achievement of adulthood criteria, associations between the two, and several personal and contextual variables. Results showed that two thirds of the sample felt in-between adolescence and adulthood. They felt more adult in work, university, and romantic relationships, and less adult with parents, friends, and siblings. The most achieved criteria were in the areas of Norm Compliance and Independence, whereas Role Transitions had been achieved the least. A variety of achievements, reflected in Independence, Norm Compliance, and Family Capacities criteria, and some concrete transitions were significantly associated with subjective adult status. Gender, age, parents’ educational level, financial constraints, and financial concerns significantly and differentially predicted the achievement of several adulthood markers. Results provide insight into the achievement of adult status within the Greek context in the aftermath of the Global Recession.

Savvakis G, Kenourgios D, Trakadas P. Digitalization as a driver of European SMEs’ financial performance during COVID-19

. Submitted.Abstract
This paper analyzes the impact of the European economy digitalization on the financial performance of the European SMEs during COVID-19. Using a panel data from 2017 to 2022 of 12,179 European SMEs and a European transformed digitalization index, we find that financial performance of SMEs is significantly and negatively associated with the COVID-19 pandemic. Digitalization of the European economy significantly increases SMEs’ financial performance measured by various performance measurements and mediates the COVID-19 negative effect. Digitalization is more significant during COVID-19 era compared to the pre-pandemic period. Our results are robust to alternative performance measures.

Although Schema Therapy has emerged as an effective treatment for a large range of psychopathology, there is limited research on its effectiveness with children and adolescents, especially for preventive purposes, in individual or group settings and with the involvement of parents. Therefore, the aim of this study was to conduct a preliminary evaluation of a newly developed group prevention program based on Schema Therapy (rationale, principles, and techniques) for children and their parents. It is a psychoeducational, developmentally-appropriate program addressing core emotional needs, early maladaptive schemas, schema modes, coping styles, and parent-child relationship with the aim of preventing the emergence of psychopathology in children. Participants were 90 Greek children (aged 9-13) who attended 16 weekly meetings and their parents who attended 10 biweekly meetings. The effectiveness of the program was evaluated with pre-and-post-intervention assessment (i.e., pre-experimental design). Children’s early maladaptive schemas (self-reports) and strengths and difficulties (self- and parent-reports), as well as parents’ early maladaptive schemas (self-reports) were assessed. Results showed a significant decrease in most early maladaptive schemas of children and in many early maladaptive schemas of parents. A significant decrease was found in children’s emotional symptoms, peer relationship problems and total difficulties score and a significant increase in prosocial behavior. The supporting evidence for the effectiveness of the program and the necessity of evidence-based prevention programs based on Schema Therapy for children and parents are discussed.

Savvakis G, Kenourgios D, Papageorgiou T. On Institutional Environment and Leverage of Small and Medium‐Sized Enterprises. Submitted.Abstract
We analyze the impact of the institutional environment on the leverage of European listed SMEs for the period 2005-2018. We use a broad range of institutional quality, judicial efficiency and corruption measures, along with several firm-specific and macro control variables, to identify different transmission channels on leverage. By performing a panel data analysis into the fixed effects filter estimator framework, along with several model specifications and robustness tests, the results show that better institutions, stronger judicial effectiveness and higher corruption decrease leverage. In terms of active transmission channels, increased investment under regimes of better institutional quality tends to increase leverage. Higher judicial efficiency accompanied by increased profitability tends to decrease, while higher institutional quality accompanied by higher investments tends to increase leverage, bringing more bank credit. Increasing profitability under regimes of decreased corruption decreases leverage. This last finding is even more pronounced for medium enterprises, as opposed to micro enterprises. The most significant factors associated with leverage are profitability, asset structure, cost of borrowing, stock market development and size, while an age effect is rejected. Pecking order theory seems to better fit the European SMEs capital structure choices under several institutional states.

Androulidakis I, Mohsen O, Yuncken R. A pseudodifferential calculus for maximally hypoelliptic operators and the Helffer-Nourigat conjecture. [Internet]. Submitted. Publisher's VersionAbstract
Given a filtration of the module of vector fields on a smooth manifold, we define a pseudodifferential calculus where the order of a vector field is given by the filtration. We show that pseudodifferential operators have a well-defined principal symbol for a subset of the unitary representations of the osculating groups. We prove a Rockland-type theorem, showing that the invertibility of the principal symbol is equivalent to maximal hypoellipticity. This answers affirmatively a conjecture due to Helffer and Nourrigat.
