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
Les inégalités sociales au spectre du « CoVid Learning Gap »
No full textLes restrictions sanitaires imposées par la pandémie mondiale initiée par l’apparition du virus de la CoVid 19 ne sont pas sans influences sur le monde de l’éducation. Ainsi, depuis le début de l’année 2020 et les premières fermetures d’établissements d’enseignement, l’effet d’une période de confinement sur les inégalités sociales de réussite académique a été régulièrement questionné par les acteurs de l’éducation. Les discours médiatiques et politiques ont principalement évoqué la dimension matérielle de ces inégalités pour en supposer les conséquences en termes d’apprentissage (i.e., les foyers aux revenus les plus modestes présentant un accès plus limité aux ressources numériques de l’enseignement à distance, notamment). Nous exposons ici une brève revue de connaissances permettant d’appréhender, dans leur pluralité, les facteurs intervenant dans cet accroissement des inégalités
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
Dissociable brain components for inhibitory control: A source separation analysis of cancelling and stopping actions
No full textPrevious work has drawn an inhibitory brain network by investigating the cancellation of prepared–discrete actions, thus focusing on an isolated aspect of human behavior. Indeed, ongoing–continuous actions, which have been associated with distinct brain mechanisms for generation, are also crucial to be stopped. Still, it is unknown whether the same inhibitory network generalizes to various situations, including cancelling a prepared–discrete action and stopping an ongoing–continuous action. We used independent component analysis of EEG data to show that cancelling and stopping action rely on independent brain components for inhibition. Indeed, the brain component which best explained inhibition when cancelling action was not involved in stopping action, and reciprocally. The analysis of these components showed that a Delta/Theta power increase generically indexes inhibitory activity, while N2 and P3 event-related potentials do it in a specific way. Sources reconstruction further identified dissociations in the brain areas generating the two inhibitory components. The differences identified between the two source generators underlie some specific activities of the inhibitory network involved in cancelling a prepared–discrete action and stopping an ongoing–continuous action. Thus, increased activity was observed in precentral gyri and posterior parts of the cingulate cortex when action cancelling, while a higher activity was found in more frontal gyri and anterior parts of the cingulate cortex when action stopping. Overall, the present findings support the idea that inhibitory control is differentially implemented according to the type of action to revise
