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
Organizational and Individual Determinants of Atypical Employment: The Case of Multiple Jobholding and Self-Employment
Get PDFTraditionally, the company has been attributed relative control over employees' career paths, particularly in the case of very active organizational management. However, the growing need for organizational flexibility has led to the increasing recourse to atypical work, which in turn contributes to consolidating new careers in which the themes of control and autonomy acquire new meaning. Of these forms of atypical work, multiple jobholding and self-employment have particularly intrigued researchers. Using data compiled by Statistics Canada, we have sought to identify, through logistic regression analyses, the factors that influence the probability of belonging to these two categories of atypical employment. Our results suggest that the influence factors are not identical for the non-standard two job categories studied. Sector of activity, sex and the absence of promotion have a considerable impact on the probability of joining the ranks of the self-employed, whereas professional category and frequency of movement significantly influence the probability of belonging to the multiple jobholder group. Our results also show that the makeup of the populations engaging in these two forms of atypical work is not homogeneous, and that belonging to one of these groups does not necessarily entail precarious living and working conditions.
Le rôle traditionnel de la gestion de carrière attribuait à l'entreprise un certain contrôle sur le cheminement des individus, dans la mesure où la prise en charge organisationnelle était très active. Toutefois, le besoin incessant de flexibilité organisationnelle, qui mène à l'utilisation croissante du travail atypique, contribue à la consolidation des nouvelles carrières dans lesquelles les thèmes du contrôle et de l'autonomie sont questionnés. Parmi ces formes de travail atypique, le cumul d'emplois et le travail autonome/à son compte ont particulièrement retenu l'attention des chercheurs. En utilisant des données produites par Statistique Canada, nous avons cherché à identifier, par l'entremise des analyses de régression logistique, les facteurs qui influencent la probabilité de faire partie de ces deux catégories d'emploi atypique. Nos résultats suggèrent que les facteurs d'influence ne sont pas les mêmes pour les deux catégories d'emploi non standard considérées. Le secteur d'activité, le sexe et les promotions jouent davantage sur la probabilité de joindre les effectifs des autonomes/à son compte alors que la catégorie professionnelle, la fréquence du mouvement et l'absence de promotion influencent davantage la probabilité d'appartenir au groupe des cumulards. Finalement, nos résultats montrent que les effectifs de ces deux types de travail atypique ne sont pas homogènes et que l'appartenance à l'un ou l'autre de ces groupes n'implique pas exclusivement la précarité des conditions de vie et de travail.Multiple jobholding, self-employment, new career, Travail atypique, cumul d'emplois, travail autonome/à son compte, flexibilité organisationnelle
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
