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
Democracies under rising inequality: New tests of the redistributive thesis
No full textRecent increases in income inequality have led a number of authors to question the redistributive thesis, which predicts higher levels of income inequality will be met with increased redistribution of income, curbing inequality. This dissertation offers a new test of this theory, and sets out to understand the great variation maintained across nations regarding their redistributive policies. In light of expectations that the future will bring further increases in income inequality, findings of this dissertation show that this will unambiguously will put pressure on governments to increase their redistributive efforts and on social insurance schemes to cover the increased career risks facing workers
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
Carrot and Stick: Experiments With Social Welfare Policies
No full textIn many countries around the world, citizens can rely on state-organized income support in situations of financial need. Examples are minimum income schemes, which pay a subsistence income to alleviate poverty and enable participation in social life, and social insurance schemes, which offer compensatory support in case of unforeseen income shocks. The question of how to organize such schemes so that they remain supportive while activating benefit claimants is subject to an ongoing debate in society and policymaking. The four empirical studies included in this dissertation address various questions raised in this debate. What happens when a welfare office eliminates job search targets and stops monitoring benefit claimants? Are financial incentives, such as benefit sanctions or higher exemptions for earnings next to benefits, effective ways to change claimants’ behavior? How do people respond to a minimum income with few strings attached? Using large administrative datasets and two randomized field experiments in the Netherlands and Spain, the four studies yield important lessons for designing income support policies. Among these insights are: eliminating effort requirements and monitoring of job seekers does not reduce job finding—however, job seekers are more likely to find jobs with a permanent contract. Allowing claimants to keep a larger share of earnings on top of benefits can stimulate part-time work in addition to benefits, but does not affect chances of full-time employment. Issuing a warning instead of cutting benefits when violating job search targets may be more effective in promoting future search behavior. And lastly, generous and unconditional income support may lead to a reduction in work on average, but those that drop out of the labor force are primarily workers with care responsibilities at home
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
