	abstract = {The recent detection of high energy gamma -rays coming from supernova remnants and active galactic nuclei has revived interest in the diffusive shock acceleration of electrons. In the present paper we examine the basis of the so-called {\textquoteleft}{\textquoteleft}box{\textquoteright}{\textquoteright} model for particle acceleration and present a more physical version of it. Using this we determine simple criteria for the conditions under which {\textquoteleft}{\textquoteleft}pile-ups{\textquoteright}{\textquoteright} can occur in shock accelerated electron spectra subject to synchrotron or inverse Compton losses (the latter in the Thompson limit). An extension to include nonlinear effects is proposed.},
