Peers, Neighborhoods and Immigrant Student Achievement: Evidence from a Placement Policy
Get PDFImmigrants typically perform worse than other students in the OECD countries. We examine to what extent this is due to the population characteristics of the neighborhoods that immigrants grow up in. We address this issue using a governmental refugee placement policy which provides exogenous variation in the initial place of residence in Sweden. The main result is that, for a given share of immigrants in a neighborhood, immigrant school performance is increasing in the number of highly educated adults sharing the subject’s ethnicity. A standard deviation increase in the fraction of highly educated adults in the assigned neighborhood increases compulsory school GPA by 0.9 percentile ranks. This magnitude corresponds to a tenth of the gap in student performance between refugee immigrant and native-born children. We also provide tentative evidence that the overall share of immigrants in the neighborhood has a negative effect on GPA.peer effects, ethnic enclaves, immigration, school performance

Peers, Neighborhoods and Immigrant Student Achievement - Evidence from a Placement Policy
Get PDFWe examine to what extent immigrant school performance is affected by the characteristics of the neighborhoods that they grow up in. We address this issue using a refugee placement policy which provides exogenous variation in the initial place of residence in Sweden. The main result is that school performance is increasing in the number of highly educated adults sharing the subject’s ethnicity. A standard deviation increase in the fraction of high-educated in the assigned neighborhood raises compulsory school GPA by 0.9 percentile ranks. Particularly for disadvantaged groups, there are also long-run effects on educational attainment.Peer effects; Ethnic enclaves; Immigration; School performance
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
