Complementarities between native and immigrant workers in Italy by sector
No full textThis Chapter investigates the existence of complementarities between immigrant and native workers across sectors in Italy and the effects on wages due to immigration during the period 2011-2016. The analysis is based on a production function framework, where the aggregate labor is the result of a nested-CES function and workers are differentiated according to their educational attainment, job experience and nationality. This approach allows the analysis to estimate the elasticity of substitution between immigrant and native workers with the same education-experience level by sector. The contribution is twofold. First, it provides an estimate of the elasticity of substitution between native and immigrant workers by sector. Second, by considering explicitly the different degree of substitutability between immigrant and native workers, the analysis provides an estimate of the wage impact for the two groups of workers at sectoral level. We find noticeable differences in the elasticity parameters across sectors. Similarly, the wage impact of immigrant is remarkably different both across sectors and between immigrant and native workers

Migration and Residential Mobility Into Impoverished Rural Illinois Communities
No full text218 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2002.This dissertation examines the conditions and processes through which poor rural communities experience high rates of in-migration. Utilizing both a statewide regression analysis of migration rates in rural block groups and case studies of rural Illinois communities, it explores the causal mechanisms that initiate and maintain high rates of migration and residential mobility in these poor places. It investigates how the interplay of regional forces, community factors, and the life courses of migrants transforms rural communities from residentially stable to highly mobile, impoverished places. At the statewide level, this study used block group data from the 1990 Census to test a hypothesized model of migration into rural, impoverished Illinois block groups. The results indicate that even after controlling for employment structure and demographic characteristics, housing accessibility in the form of inexpensive rental housing is strongly associated with high levels of residential mobility and in-migration in impoverished rural block groups. The results of the case studies point to a multi-scalar process. At the community scale, poor rural communities with high percentages of affordable rental housing attract migrants. At the individual scale, migrants are drawn to these communities via social and kinship ties after "forced migrations" from their previous residence. These findings have implications for policies tackling rural development, housing, and poverty issues.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD

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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
