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

Rio de Janeiro, ville (inégalement) branchée ? Service d'électricité et divisions de l'espace urbain
Full text linkInternational audienceSymboles des favelas, les entrelacements de fils électriques apparents sont aussi celui d'un service de l'électricité qui reste profondément inégal et incertain dans les villes brésiliennes. En s'intéressant à la qualité de sa distribution à Rio de Janeiro, Francesca Pilo' montre comment ce réseau participe des dynamiques de fragmentation de l'espace intra-urbain, au-delà de la simple dichotomie entre bidonvilles et quartiers favorisés. Malgré le caractère universel du service d'électricité (en termes de couverture territoriale et d'accès physique généralisé), le réseau centralisé à Rio de Janeiro n'accomplit que partiellement sa fonction de fourniture d'un service homogène sur un territoire donné qu'il contribue ainsi à solidariser et à égaliser (Dupuy 1985). Les fils électriques visibles dans les favelas semblent être un premier révélateur d'un « réseau éclaté » (Kooy et Bakker 2008) et suggèrent la présence d'un processus de fragmentation urbaine par le réseau (Graham et Marvin 2001
Rio de Janeiro : Regularising energy consumption in favelas through reshaping consumers into customers
No full textInternational audienceThe process of regularization of access to electricity services in informal settlements is often described as a "transformation of consumers into customers". In most cases, such a transformation is to redefine poor commercial relationship and create energy efficiency measures to help adjust the consumption patterns of families to their financial capacity. Within the context of the political changes in the favelas of Rio de Janeiro where the UPP were installed (Pacifying Police Unit), this article explores the process of electricity regularization, focusing on the aspects of energy efficiency measures implemented by the distribution company service. The main purpose of this article is to show how this form of infrastructure reconfiguration is implemented through commercial logics, which in turn have consequences in the way of energy saving measures are promoted. Firstly, the article presents the articulation of two different body of literature that allow an understanding of the relationship between infrastructure, consumer practices and public policies for energy efficiency. Secondly, the article proposes an analysis of the tools used by the company and the perceptions of families. The paper argues that the measures adopted by the electricity distribution company appear at the same time, to weaken consumer understanding about their own consumption and, paradoxically, stimulate higher levels of it. The article then highlights some limits of a commercial approach to saving energy and contradictions of its policy
