Skilled Migration and Human Capital Accumulation in Southern Italy
No full textThe demographic data indicate that the total number of migrants moving from the
South of Italy to the Center and North has held basically constant in recent decades.
However, the portion of the aggregate called “high-skilled” has been increasing. That
is, the quality composition of migrant workers has undergone a radical change. Where in
the early postwar decades migrants were mostly young people from the rural parts of the
South, today increasing numbers of university graduates and students (enrolled in institutions
outside their home regions) are leaving the peninsular and island regions of the
South for the Center and North. The global literature on the measurement of the effects
of such educated migration has examined the question from two opposing standpoints,
among others: “brain drain” and “brain gain”. This paper contributes to the discussion
on the measurement of the economic effects of high-skilled migration, focusing on
the case of the Italian South. After setting out a general framework for measuring the
economic effects of educated emigration, the paper presents the empirical findings on the
impact on human capital accumulation
Shirking and Social Capital: evidence from skilled vs unskilled school workers
No full textWe study the relation between shirking behavior among workers in Italian public schools and the level of social capital across different regions. In particular, our analysis focuses on the role of regional (NUTS3 level) social capital on teachers’ absenteeism rates. Exploiting a rich dataset from MIUR, we control for a number or school and local characteristics. In addition, to address likely endogeneity problems in OLS results, we instrument social capital with the presence of different foreign dominations that ruled Italian regions between the 12th and 19th century before the creation of the unified Italian State. Our results suggest that past historical institutions play a role on the current social capital level and show that the latter has a significant effect on the absenteeism rate of teachers in Italian schools
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
