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

No full textPrésentation bicolore dans une tâche stroop : aspects sémantique et attentionnel
No full textLa tâche Stroop est une tâche très utilisée en psychologie car elle permet entre autres l'étude des processus dit automatiques. Cependant, récemment l'utilisation d'une présentation bicolore dans cette tâche, associée aux études liées à une tâche de détection de lettre dans une tâche d'amorçage, suggère que l'accès à la sémantique ne serait pas automatique. Ce qui impliquerait une interprétation différente de la tâche Stroop. Nous avons testé l'hypothèse qu'en présentation bicolore, la diminution observée de l'effet Stroop ne serait pas dû à un blocage de la sémantique mais à une augmentation des capacités d'inhibition. Nous avons pour cela utilisé une condition "associée" qui consistait à présenter des mots associés à une couleur (par exemple "ciel" associé à bleu) afin d'étudier plus spécifiquement l'accès à la sémantique. Dans nos deux premières études reproduisant le protocole des précédentes avec un nombre de participants plus important, nous n'observons pas de diminution de l'effet Stroop associé. Nous avons ensuite utilisé les potentiels évoqués pour montrer la présence de la N400 en condition bicolore pour les mots de couleurs et associés à une couleur dans la tâche Stroop. Pour finir, après avoir testé la présence du biais attentionnel chez des patients alcoolo-dépendants avec une version française du "Alcohol Stroop Test", nous avons montré que des ressources attentionnelles étaient nécessaires pour observer une diminution de l'effet Stroop en présentation bicolore. L'ensemble de nos résultats suggère que la diminution de l'effet Stroop en présentation bicolore nécessite des ressources attentionnelles et que donc l'accès à la sémantique serait un processus automatique, mieux inhibé dans la présentation bicolore. La tâche Stroop utilisée en clinique refléterait donc bien un processus d'inhibition de processus automatiques.The Stroop task is a well-used task in psychology, in particular because it allows the study of automatic process. Recently the use of a single letter coloring presentation in this task, associated with the studies related to a task of detection of letter, suggests that the access to semantics would not be automatic. This implies a different interpretation from the Stroop task. We tested the assumption that in single letter colored presentation, the reduction observed in the Stroop Effect would not be due to a blocking of semantics but to an increase on the capacities of inhibition. For that we used an "associated" condition where we presented words associated with a color (for example sky associated with blue) to more specifically study the access to semantics. In our two first studies reproducing the preceding protocol with a more important number of participants, we do not observe reduction in the associated stroop effect. Then we used the Potentials Evoked to show the presence of N400 in the single letter colored condition for color words and associated-words. To finish, after having tested the presence of an attentional bias among patients alcohol-dependent with a French version on Alcohol Stroop Test, we showed that attentional resources were necessary to observe a reduction in the Stroop Effect in single letter colored presentation. The whole of our results suggest that the reduction in the Stroop Effect in single letter colored presentation requires attentional resources. The semantic access would be an automatic process. The sense of the word could be inhibiting after activation in single letter colored presentation. The Stroop task used in clinical would thus reflect an inhibition capacity of automatic process
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
