Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
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
Virtualization of the FOAD teaching practices between context and media : the case of Pyramide network
No full textCette thèse doctorale est une étude descriptive de type mixte qui articule à la fois des données qualitatives et quantitatives. Dans un objectif heuristique de l’étude des pratiques enseignantes de Bru et selon les travaux de Tardif et Lebrun sur le paradigme d’enseignement et le paradigme d’apprentissage, cette recherche vise à identifier les homogénéités et les hétérogénéités des pratiques enseignantes à distance d’un réseau de formation en synchronie celui du réseau Pyramide. Le cadre, qui a permis l’analyse des données de la recherche, s’appuie sur trois axes capitaux : l’enseignement dans un dispositif à distance, l’organisateur des pratiques enseignantes et les différentes approches de l’enseignement en ligne. Les hypothèses de la recherche qui ont été établies sont fondées sur le croisement de ces axes. Le protocole de la recherche se base sur un questionnaire, l’échelle de Likert et des interviews semi directifs.L’analyse des données quantitatives a permis de définir les facteurs déterminants de l’homogénéité et de l’hétérogénéité des pratiques par le biais de nouveaux organisateurs, tels que l’interaction, le sentiment de maîtrise des outils et l’innovation pédagogique au sein de ce dispositif. Cette recherche confirme l’hypothèse que les pratiques des formations en ligne s’organisent autour de 30 axes que nous avons définis en fonction de l’analyse de déclaration des répondants. Mais elle ne confirme pas l’hypothèse que ce dispositif Pyramide est un organisateur d’homogénéité, malgré son caractère fort qui articule des formes pédagogiques structurées (AFT, TLP, TLT, Visio) et un discours pédagogique explicite sur la nécessaire prise en compte de l’apprenant dans les situations d’enseignement/apprentissage. Globalement, notre recherche témoigne que l’innovation pédagogique est encore loin d’être une réalité dans la FOAD et que de nombreux enseignants continuent de favoriser le paradigme d’enseignement au paradigme de l’apprentissage.This doctoral thesis is a descriptive mixed study which articulates both qualitative and quantitative data. In a heuristic goal for the study of the teaching practices by Bru and according to the works of Tardif and Lebrun on the teaching and learning paradigms, the research aims at identifying the homogeneity and heterogeneity aspects of distance teaching practices of a synchronic distance learning network, the Pyramide network. The framework allowing the data analysis of the research rests on three main axes: the teaching practices of a distance learning structure, the organizer of the teaching practices and the various approaches of e-learning. The hypothesis of the research is based on the cross study of these axes. The research protocol is based on a questionnaire, the scale of Likert and semi-structured interviews. The analysis of the quantitative data allowed the definition of key factors for homogeneity and heterogeneity of the practices through new organizers such as interaction, sense of mastering technological tools and pedagogic innovation within the Pyramide structure. The research confirms the hypothesis that the e-training practices are organized around thirty axes that we have defined following the analysis of the trainers’ statements. However, it does not confirm the hypothesis that the Pyramid network is an organizer of homogeneity in spite of the strong character of the system which articulates structured pedagogic methods (AFT, TLP, TLT, visio) and an explicit pedagogic discourse rightfully centered on the learner in the teaching/learning situation. Overall, our research shows that pedagogic innovation is far from a reality in FOAD and that many teachers still favour the teaching paradigm over the learning paradigm
