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

Full text linkCette thèse est présentée dans le cadre du Doctorat en Sciences Médicales de l’Université de Liège (ULg). Elle porte sur l’utilisation des benzodiazépines hypnotiques et anxiolytiques, leur probabilité d’évolution vers une dépendance à haut dosage et leur risque de mortalité.La partie générale résume les indications des benzodiazépines, leurs types et leurs particularités. Elle passe en revue les caractéristiques diagnostiques de l’intoxication aiguë et propose une classification clinique de l’usage à problèmes des benzodiazépines. Elle décrit également le sevrage de ces substances et résume les critiques de la recommandation de passer des benzodiazépines aux inhibiteurs sélectifs de la recapture de la sérotonine dans le traitement des troubles anxieux.La partie empirique inclut des données épidémiologiques et propose une définition de la consommation « à haut dosage ». Elle soulève l’hypothèse que des différences existent entre les benzodiazépines, et plus particulièrement entre benzodiazépines anxiolytiques et benzodiazépines hypnotiques. Elle présente les résultats de la recherche faite dans le cadre de cette thèse. Elle esquisse également des données compilées au niveau de la mortalité « toutes causes confondues » associée avec les benzodiazépines et discute les biais probables.La partie réflexive discute des conclusions et actions à prendre à partir des résultats de cette thèse. Elle récapitule les mesures de prévention déjà en vigueur, et énonce des recommandations concrètes. Elle propose des études à faire à l’avenir.This thesis is presented as part of the PhD in Medical Sciences of the University of Liège (ULg). It provides an overview of the use of benzodiazepine hypnotics and anxiolytics, their likelihood of progression to high-dose dependence and their mortality risk. The general section summarizes the indications of benzodiazepines, their types and their characteristics. It reviews the diagnostic features of acute intoxication and provides a clinical classification of the problematic use of benzodiazepines. It also describes the withdrawal of these substances and summarizes the criticisms of the recommendation to move from benzodiazepines to selective serotonin reuptake inhibitors in the treatment of anxiety disorders.The empirical section includes epidemiological data and proposes a definition of « high-dose use ». It raises the hypothesis that differences exist between benzodiazepines, especially between anxiolytic and hypnotic benzodiazepines. It presents the results of research done in relation to this thesis. It also outlines the preliminary results of mortality from all-cause associated with benzodiazepines and discusses the likely biases.The discussion debates the findings and actions to be taken on the basis of the results of this thesis. It summarizes the preventive measures already in place and sets out concrete recommendations. It suggests studies to be undertaken in the future
