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
Mesurer la discrimination de la population envers les personnes souffrant de troubles psychiatriques : adaptation et validation française du questionnaire « Attitudes to Mental Illness 2011 ».
No full textObjectif : Le concept de stigmatisation, tel que défini par Thornicroft, renvoie aux problèmes de connaissance (ignorance), d'attitudes (préjugés) et de comportement (discrimination). La stigmatisation peut entraver l'accès aux soins, au logement et au travail. Dans le cadre de la mise en œuvre dans les régions francophones de programmes tels que « logement d'abord » ou « placement individuel et accompagnement », des instruments validés mesurant la stigmatisation sont nécessaires. « Attitudes to Mental lllness 2011 » est un questionnaire qui comprend trois échelles mesurant la stigmatisation à travers ces trois dimensions. L'étude de cette thèse a comme objectif de traduire, adapter et valider ces trois échelles en français.
Méthodes : Le questionnaire « Attitudes to Mental lllness 2011 » a été traduit en français et rétro-traduit en anglais par un expert. Deux cent soixante-huit étudiants en soins infirmiers ont rempli le questionnaire. La validité du contenu, la validité d'apparence, la validité interne et la validité convergente ont été évaluées. La fiabilité à long terme a également été estimée sur une période de trois mois.
Résultats : Les experts et les participants ont trouvé que la validité du contenu du questionnaire et sa validité d'apparence étaient appropriées. Les validités internes des trois échelles ont également été jugées adéquates. La validité convergente indiquait que les échelles mesuraient effectivement ce qu'elles étaient censées faire. La stabilité à long terme a été modérée; ce modèle de résultats suggère que le construit étudié par les trois échelles est correctement mesuré, mais ne représente pas nécessairement des traits stables et durables.
Conclusion : En raison de leurs bonnes propriétés psychométriques, ces trois échelles peuvent être utilisées en français, soit séparément, pour mesurer une dimension spécifique de la stigmatisation, soit ensemble, pour évaluer la stigmatisation selon les trois dimensions définies par Thornicroft. Cela semble d'une importance primordiale dans l'évaluation des campagnes contre la stigmatisation, car elle permet d'adapter les mesures en fonction des objectifs de la campagne et de la population cible
