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
Does self-employment contribute to immigrants' economic integration? Examining patterns of self-employment exit in Belgium
No full textAbstract: This article assesses whether self-employment can help immigrants overcome some of the ongoing challenges they face in highly segmented labor markets, by investigating the reasons behind native-immigrant differences in exit from self-employment. While a considerable literature examines the factors influencing immigrants\u2019 decision to become self-employed, surprisingly few studies address the factors that shape exit from self-employment. This article studies native-immigrant differences in self-employment exit, drawing on longitudinal data (2008\u20132017) for Belgium, and adds to previous research on immigrant self-employment by considering second-generation and female immigrant business owners. Results show that immigrants were much more likely than natives to become unemployed or leave the labor force after a period in self-employment, supporting the idea that immigrants are pushed out of self-employment. Second-generation immigrants generally had better self-employment outcomes than first-generation immigrants, whereas female immigrants sometimes experienced a \u201cdouble disadvantage.\u201d Weaker attachment to the labor market preceding self-employment entry helps explain why immigrants had worse self-employment outcomes than natives in Belgium. Hence, self-employment may not provide an independent path to economic integration that allows immigrants to overcome the hurdles they face in the labor market. Instead, how people fared in the labor market before becoming self-employed strongly influenced their success as self-employed workers. This article highlights the policy complexity of immigrants\u2019 labor market integration in Western European labor markets. As it shows, it is not enough to promote self-employment as an easy way out of immigrants\u2019 labor market exclusion. Instead, more is needed to counteract immigrants\u2019 problematic labor market outcomes
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Is labour migration hurting migrant labour? Empirical investigations for the case of Belgium
No full textAbstract: This dissertation investigates labour migration towards Belgium and the problematic labour market integration of immigrants in Belgium. The dissertation title \u2013 Is labour migration hurting migrant labour? \u2013 refers to the central tension that motivated the writing of this doctoral thesis. On the one hand, Belgium (and, by extension, Europe) needs labour migration. Due to growing labour shortages, skill mismatches and cost concerns, Belgium continuously imports migrant labour sourced from the other Member States and non-EU countries. On the other hand, however, Belgium already has a significant labour reserve of unemployed, inactive and underemployed people, many of whom are immigrants. While (labour) migration seems critical for the European and Belgian labour market and society, immigrants\u2019 labour market incorporation remains a formidable challenge. Often it is mentioned that Europe needs more labour migration. However, the reality on the ground is that there are already high labour migration levels. I refer here to the under-highlighted phenomenon of the posting of workers, which has provided the Belgian and European labour markets with very high numbers of temporary workers who are legally not part of the labour market but who nevertheless are indispensable in specific sectors of the economy. If we consider posting as part of the migration landscape, much more labour inflow is occurring than is usually presumed. The immense popularity of posting in Belgium and Europe highlights the severity of the labour market integration problem of resident immigrants. Any academic theory considers the lack of host-country language skills, recognition of foreign educational credentials and social networks as severe impediments to immigrants\u2019 economic integration. Paradoxically, however, none of these barriers \u2013 seemingly hard to overcome for \u2018proper\u2019 immigrants \u2013 are at play for posted workers. Posted workers are the quintessential outsiders who are much more in demand on the local labour market than \u2018regular\u2019 immigrants who aspire to become insiders. This dissertation contributes to the international state-of-the-art on immigrant labour market integration and labour migration by conducting an empirical investigation of these tensions for the case of Belgium
