University students’ drop-out is a crucial issue for the universities’ efficiency evaluation and funding. In this paper, we
analyze the drop-out rate of the Economics and Business faculty of Sapienza University of Rome. We use administrative data
on 9,725 undergraduates students enrolled in three-years bachelor programs from 2001 to 2007 and perform a Generalized Linear
Mixed Model. Our aim is to improve the general understanding of the students’ withdrawing focusing on personal characteristics
of students rather than on institutional aspects of the university. The empirical analysis unveils the statistically significant
effect of students’ characteristics, like citizenship and income, while the main findings relate a high drop-out probability
to a high secondary school final mark and a low individual students’ performance. 相似文献

In line with an Aboriginal worldview of interconnectivity, I outline successful educational programs, policies, and services for Aboriginal peoples in Canada. These programs and initiatives are presented within four thematic areas related to (a) early childhood education, (b) Aboriginal pedagogy, language, and culture (throughout kindergarten to Grade 12), (c) postsecondary education, and (d) governance and partnerships. These issues are then positioned within the concept of ethical space. The insight from this information is intended to assist teachers, educational leaders, and policy makers in promoting ongoing educational achievement for Aboriginal learners. 相似文献
