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
Prédiction de la défaillance de la clientèle du micro crédit au Maroc : méthodes des scores
Full text linkLe développement de la micro finance au Maroc date du milieu des années 1990 et devient particulièrement dynamique au cours des années 2000. Actuellement, ce secteur commence à connaître de multiples risques notamment celui du crédit.En effet, le risque de crédit, susceptible d’entraver l’émergence des établissements de micro-finance, est devenu l’une des préoccupations principales des institutions financières. Ainsi, une place importante mérite d’être réservée au métier de la gestion des risques d’insolvabilité des emprunteurs notamment à travers l’anticipation de leurs défaillances. Cet objectif d’anticipation est réalisable à travers l’utilisation d’une technique de scores qui permet d’affecter un individu en l’un des groupes à savoir les bons clients et les défaillants.En s’inspirant des enseignements sur la fonction de discrimination présentés par (SAPORTA,1975), le discernement peut être effectué selon les caractéristiques socio-économiques et démographiques de chaque client et compte tenu des modalités prises par les différentes variables.Le calcul des scores nous a permis élaborer un filtre de discrimination permettant de noter les clients, d’identifier des classes de risque et de repérer ceux susceptibles de tomber défaillants à la date de remboursement
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
La stratégie des entreprises marocaines du textile et habillement : Une note empirique
Full text linkLe présent papier, inspiré de la théorie du management des organisations, se propose de vérifier l’existence d’une stratégie auprès des entreprises du secteur « textile et habillement » marocain. Cette vérification a été menée à partir de l’identification des différentes composantes de la stratégie adoptée par les entreprises du même secteur.A cet effet, la méthodologie adoptée repose sur une revue théorique qui a abouti à des conclusions importantes quoiqu’elles restent abstraites. Ces notes théoriques ont été confrontées avec une investigation empirique sur 26 entreprises marocaines du secteur textile et habillement, à titre de rapprochement. Les points étudiés concernent l’influence du processus de surveillance sur l’environnement, l’importance de la maîtrise des ressources et des compétences, l’exercice du contrôle des facteurs déterminant le développement de l’entreprise et les facteurs expliquant la stratégie explicite.Les résultats empiriques montrent que la majorité des entreprises s’orientent vers l’adoption d’une approche stratégique. Toutefois, elles manifestent leur besoin de soutien de l’Etat pour concrétiser leur évolution à travers des actions de mise à niveau. D’autres entreprises ont été amenées sous l’effet de l’écoute de l’environnement à reconnaître le rôle de la vision et de la planification. Egalement, il a été vérifié que la stratégie se manifeste progressivement au cours du processus de développement de l’entreprise
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
Firm Performance: Definition and Measurement Models
Full text linkThe business environment of this new century has undertaken several changes, creating more and more complexity and uncertainty. In this changing environment, which characterizes the global economy today, firms face severe competitive pressure to do things better, faster, and low-priced. They need to cope with a growing number of challenges arising fromtheir environment, and also increase their ability to adapt. Nowadays, continuous performance is the objective of any firm. This is because it is only through performance that companies are able to experience development and make progress. Consequently, assessing and measuring business performance is of significant importance, since companies are constantly seeking effective and efficient results
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
