Un approccio longitudinale alla valutazione degli esiti occupazionali dei corsi di formazione professionale
Full text linkThe article shows how to apply the sociological approach of life courses to the evaluation research on the occupational outcomes of vocational training courses. In the first part we review the main principles of the life-courses approach. In the second section we describe the main features of the research Placement 2006 conducted by IReR (Regional Research Institute of the Lombardia); in particular, we focus on the research design and the procedures used to collect information. In the last part we present an empirical application of event history techniques. We use sequence analysis to examine occupational careers after the end of the vocational training courses and survival analysis to study the duration of unemployment episodes by gender and type of course. At the end, we briefly discuss the pro and cons of this approach and we suggest further development within this framework

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
