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
Drowning risk management in the public swimming pools of Caen la mer : organizational analysis and security optimization perspectives
No full textMalgré une surveillance constante exercée par les MNS, des noyades surviennent dans les PPAP. La thèse propose une analyse systémique et organisationnelle du risque de noyade dans ces équipements. Elle s'appuie sur une méthodologie qualitative plurielle : une analyse documentaire visant à quantifier le phénomène accidentel doublée de 9 entretiens d'experts (partie C), des observations de terrain menées dans 108 PPAP dans l'optique d'objectiver l'effectivité de la surveillance (partie D) et des entretiens semi-directifs afin de cerner les causes profondes des inadéquations : (n=27) à titre expérimental au sein d'une métropole du Grand-Ouest à l'occasion d'une mission d'expertise commanditée et (n=30) au sein de la communauté d'agglomération Caen la mer (partie E). Les résultats obtenus montrent que : 1) la production de données quantitatives sur la noyade en PPAP est entravée par un certain nombre de barrières faisant de cette question un « angle mort » de la connaissance ; 2) la surveillance exercée par les MNS est dégradée la moitié du temps d'observation et que 3) les arbitrages managériaux, la dynamique organisationnelle, mais aussi les représentations des acteurs interfèrent avec la fonction de surveillance, exerçant une influence sur sa réalisation et sa qualité. Les travaux mettent en évidence la coexistence et la redondance de boucles de rétroaction relativement efficaces mais peu coordonnées, articulées de manière contingente et inscrites dans différents registres. Aléatoire quant à son efficacité, la surveillance exercée par les MNS renvoie à une tâche difficile, fortement contrainte et de surcroît sujette à des formes plurielles d'adaptation. Ce travail montre que la gestion des risques dans ces équipements ainsi que les pratiques actuelles sont perfectibles. A ce propos, des recommandations à même d'optimiser la gestion des risques et la surveillance des bassins ont pu être formulées. Des actions préventives ont du reste été engagées (partie F)Drownings occur in PSP (public swimming pool) despite lifeguard supervision.The thesis proposes a systemic and organizational analysis of the drowning risk in PSP based on a combined qualitative methodology : a documentary analysis aimed at quantifying the accidental phenomenon coupled with 9 expert interviews (part C), field observations conducted in 108 PSP in order to objectifying the effectiveness of supervision (part D) and semi-structured interviews to identify the root causes of mismatches : (n = 27) in experimental way for a Grand-Ouest metropolis within the framework of an expertise mission and (n = 30) within the Caen la mer community (part E). The results of the study show that : (1) the production of quantitative data on PSP drowning is hampered by several barriers that make this issue a “blind spot” of the knowledge ; 2) the supervision by lifeguard is degraded half of the observation time and 3) managerial arbitration, organizational dynamics, but also social representations of the actors interfere with the supervision function, exerting influence on its realization and quality. The work highlights the coexistence and redundancy of feedback loops that are relatively efficient but not coordinated, articulated in a contingent way and included into different registers. Monitoring by lifeguards, which is random about its effectiveness, refers to a difficult task, which is highly constrained and, moreover, subject to plural forms of adaptation. This work shows that the management of the drowning risks in these equipment and the current practices are perfectible. Moreover, recommendations were formulated to optimize risk management and pool supervision. Preventive action was also launched (Part F
