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
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
Évolution floristique et structurale d’un recrû forestier en Guyane française
No full textThe structure and floristic composition of a secondary forest was studied, 11 1/2 years after clear cutting, at the Piste de St-Elie study site, French Guiana.
Three hundred and eight species were identified on the 25 ha study plot, against 163 species only eight years earlier. Pioneer species were still the most numerous on this plot in 1988, 12 of them representing 58 % of the woody plants enumerated (Tab. III). However, the number of Cecropia obtusa greatly diminished between 1980 and 1988, and 71 % of the standing individuals remaining were obviously withering. Among all plant families already present in 1980, the number of species increased during the following 8 years, except for the Solanaceae which disappeared completely (Tab. IV). Many species present in the undergrowth and the canopy of the surrounding mature forest made their appearance in the study plot during the same 8 year interval.L’étude d’un transect de végétation dans un recrû naturel de 25 ha après coupe rase dans la région de la Piste de St-Elie, Guyane française, montre :
• L’importance numérique des espèces pionnières 11 ans et demi après le défrichement (12 espèces représentent près de 58 % de l’effectif des ligneux recensés).
• La disparition des Solanum (Solanaceae) et le dépérissement d’autres pionniers (principalement Cecropia obtusa, Moraceae).
• L’apparition ou la progression dans le recrû d’espèces du sous-bois et des strates supérieures de la forêt primaire voisine.
• Une variabilité structurale importante, correspondant à plusieurs groupements de végétation. Les formations les plus proches de la forêt primaire présentent la régénération la plus avancée.Larpin Denis. Évolution floristique et structurale d’un recrû forestier en Guyane française.
