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
Occupational asbestos exposure and psychological distress determinants
No full textEntre 2003 et 2005, un programme de dépistage des maladies liées à l’amiante a été mis en place dans quatre régions françaises, constituant ensuite la cohorte ARDCO (Asbesto related Diseases Cohort). La cohorte ARDCO a été suivie entre 2007-2009 (étude ARDCO I) et entre 2011-2012 (étude ARDCO II). Cette thèse a été réalisée dans le cadre de l’étude ARDCO II et trois études ont été réalisées. Dans notre population d’étude, nous avons montré une amélioration de certaines connaissances sur le risque lié à l’amiante et au tabac par le biais d’une notice d’information. La prévalence globale des symptômes d’anxiété probable et de dépression probable a été respectivement estimée à 19,7% (n=435) et 9,9% (n=219). Les femmes présentaient significativement plus de symptômes anxieux et dépressifs que les hommes (respectivement 34,8% contre 19% et 18,5% contre 9,5%). Le risque de développer les symptômes anxieux et dépressifs était significativement associé à l’auto-évaluation de l’exposition à l’amiante, la perception du risque lié à l’amiante ainsi qu’à l’autoperception du risque de développer des pathologies liées à l’amiante. Une troisième étude a montré que les personnes présentant des symptômes d’anxiété probable ou de dépression probable utilisaient le plus souvent les stratégies de coping dites « maladaptatives » ; et que l’utilisation des stratégies de coping dépendait plus de la présence des symptômes anxieux ou dépressifs que de l’exposition à l’amiante.A large-scale screening program for asbestos-related diseases was organised in four regions of France between October 2003 and December 2005. Asbestos Related Diseases Cohort was constituted and participants were followed up between 2007 and 2009 (ARDCO I study) and between 2011 and 2012 (ARDCO II study). This thesis was made from ARDCO II study and three studies have been conducted. Among the study participants, we found an improvement in knowledge about tobacco and asbestos-risk perception related to an information leaflet. The prevalence of symptoms of probable anxiety and depression was 19.7% (n=435) and 9.9% (n=219) respectively. Women had significantly more anxious and depressive symptoms than men (34.8 vs 19% and 18.5 vs 9.5, respectively). The risk of developing anxious and depressive symptoms was significantly associated to the intensity of asbestos-exposure self-evaluated and to the asbestos-risk perception. The participants with symptoms of probable anxiety or depression more frequently used “maladaptive” coping strategies and the use of the coping strategies depended specially of anxious and depressive symptoms rather than asbestos exposure
Agressions respiratoires des expositions aux contaminants professionnels et leurs conséquences sur la santé mentale
No full textDe multiples activités professionnelles, en milieu agricole, industriel ou dans le secteur du bâtiment peuvent, ou ont pu, exposer les travailleurs à l’inhalation de gaz, poussières, fumées et/ou aérosols. Ces derniers peuvent de nature variable : particules minérales par exemple amiante ou silice, mélanges complexes de gaz et particules métalliques dans les fumées de soudage, particules végétales chez les agriculteurs ou les boulangers, bioaérosols constitués de micro-organismes bactériens ou fongiques chez les agriculteurs mais également chez les usineurs en cas de contaminations de fluides de coupe. Ces expositions, facteurs d’agressions de l’appareil respiratoire peuvent favoriser l’apparition de pathologies diverses, variables selon la nature de l’exposition : troubles ventilatoires obstructifs (asthme, BPCO), pneumopathies interstitielles (pneumoconioses, pneumopathies d’hypersensibilité voire fibroses pulmonaires idiopathiques) mais aussi, pour certaines expositions, de cancers. Ces derniers surviennent souvent plusieurs dizaines d’années après l’exposition pouvant engendrer un phénomène d’épée de Damoclès. Ainsi chez certains sujets ayant été exposés à l’amiante inclus dans des programmes de surveillance un impact sur la santé mentale (anxiété et dépression) et sur la santé perçue a être pu être observé. L’exploration des déterminants de cet impact sur la santé mentale et sur la santé perçue des expositions à l’amiante voire à d’autres cancérogènes professionnels mérite d’être approfondie
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
