Abstract


The network of student transfers within the system of the University of Bologna are presented as a network approximate a scale-free topology, where, the assumption of incremental grow is not fulfilled, due to the influence exercised on the network by law restrictions and institutional decisions applied to courses. In such a network the link was defined by the transfer rate of the degree course (computed as the ratio of the number of transfers to the number of students enrolled) and the critical points of the system were defined by the courses characterized by a high out-transfer rate. In order to preview the evolution of critical points in dependence of constraint modifications, a beta regression model is proposed, that fit links represented by quantities varying between 0 and 1
