Stratification mechanisms in labour market matching of migrants
Get PDFI aim to challenge the standard framework in which systematic exclusion is mistakenly characterised as only a frictional phenomenon that fails to be captured in migrants' labour market matching mechanisms. Societies organise and rank people in a hierarchical way, not only in terms of individual differences and characteristics but with respect to social groups and categories of people. These macro patterns systematically subject some migrant groups to different forms of exclusion. Social stratification, explained in terms of social identity-based institutional structures, organises labour markets into different destinations like clubs with sharply different sets of opportunities. It functions like a trap for migrants: it reinforces itself by reproducing systems of exclusion and creates dilemmas for migrants. Can migrants organise themselves to avoid such traps? I show that exclusion is endogenous to employment as a type of good in the standard goods typology. Treating different types of employment opportunities as being like clubs, I investigate how migrants join or create alternative employment clubs as a response to real or perceived exclusion from native employment clubs. If these alternative clubs are 'sticky' and discourage migrants from trying to join natives' exclusive employment clubs, the trap becomes inescapable. For migrants to escape the stratification trap, employment should be seen not only as an investment but as a collective action problem structurally targeting exclusion
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Building Diversity Into the Philosophy and Methodology of Economics with Stratification Economics
Get PDFMainstream economics ignores who produces it and what it is about because its average man, Homo economicus ontological entry-point obscures social differences between people. Philosophy and Methodology of Economics that assumes this ontological entry point generally limits itself to epistemological analysis, and this means it fails to make diversity a fundamental concern. Taking diversity seriously entails being clear about one\u27s ontological assumptions, and this requires being clear about the normative scope of one\u27s analysis. This calls for giving up a value-neutral methodological reasoning and adopting a value-explicit methodological posture. To illustrate, we describe how Stratification economics with its social groups ontological entry-point shows societies are structured around hierarchical social group rankings that differentiate people according to their social identity status. We explain this in both micro-level and macro-level terms, show that together they produce systems of inclusion and exclusion, and argue that this raises issues of equality and justice
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
