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
How to prioritize the ludème defects of a serious game in IS?
No full textCette thèse s'intéresse au jeu en termes de technologies de l’information et à son adoption et instrumentalisation au sein de l'Université. Notre attention se porte sur les questions organisationnelles, managériales et de conception de cette adoption. Les écosystèmes universitaires semblent réticents face aux innovations pédagogiques mais accueillants face aux pédagogies ludiques ce qui interroge le chercheur en sciences de gestion sur l'écologie de la transformation universitaire au sens de la transformation organisationnelle. Nous argumentons que l'Université reste organisée à l'image d'une bureaucratie professionnelle mintzbergienne mais avec une écologie organisationnelle explicative des jeux sérieux en ce milieu. Nous poserons alors la question de la conception des serious games répondant à la fois aux besoins des enseignants, des concepteurs et des étudiants. Nous suggérons que bug trackers et AMDEC, fréquemment utilisés en conception répondent à des problèmes de coordination tels les objets frontières définis par BECHKY. De plus, ces objets frontières n'intégreraient pas selon nous, les utilisateurs finaux à la conception. L'objet de notre recherche consiste à suggérer le design d'un dispositif aidant à la conception pédagogique et en SI de jeux sérieux à vocation universitaire. Démarche de type “design science” basée sur les travaux de BASKERVILLE et HEVNER. Ce design implique une caractérisation du ludème pour définir le défaut de ludème. Nous appuyant sur JUUL et GIBSON nous proposons que le ludème de jeu sérieux se définisse par l’affordance, la règle de jeu et le score préconisé par JONES, SCHAMROTH ET LAMERAS sous la forme du leaderboard. Nous adaptons ensuite l'AMDEC aux défauts de ludèmes en gardant sa fonction d'objet frontière. Enfin nous examinons les opportunités et limites de notre recherche doctorale.This thesis in focused on games in terms of information technology and their adoption and instrumentalization within University. Our attention is focused on the organizational, management and design issues of this adoption. University ecosystems seem reluctant to accept pedagogical innovations but welcoming towards game enhanced pedagogies. This questions us on the ecology of University transformation in the sense of organizational transformation. We argue that the University remains organized as an mintzbergian professional bureaucracy but with an organizational ecology that may support serious games in such an environment. We then explore the design of serious games that meet the needs of teachers, game designers and students. We suggest that bug trackers and FMEA, frequently used in design, respond to coordination problems such as boundary objects defined by BECHKY. These boundary objects do not, in our view, integrate end users into the design. We suggest the design of a device for IS and educational design of serious games used in Universities. We carry a “design science” type approach following BASKERVILLE and HEVNER. This design involves characterizing the ludème in order to define the ludème defect. Based on JUUL and GIBSON we suggest that ludèmes may be defined by rules and affordance to which we add a leaderboard score recommended by JONES, SCHAMROTH AND LAMERAS. We then adapt the FMEA to ludème defects while keeping its boundary object function. Finally, we examine the opportunities and limits of our doctoral research
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

Proposal for a model for analyzing the determinants of the acceptance and use of online tax reporting tools in Morocco
No full textCe travail doctoral s’intéresse aux facteurs d’acceptation, d’adoption puis d’utilisation des technologies de l’information de type e-gouvernement. Il s’intéresse en particulier au cas de la télédéclaration fiscale au Maroc. Partant d’une posture épistémologique positiviste, la recherche s’appuie sur une démarche méthodologique mixte en deux étapes, la première est basée sur une démarche qualitative exploratoire reposant sur la méthode Delphi et la seconde s’appuie sur une démarche quantitative par équations à vocation confirmatoire. Son objectif est classique et en cohérence avec le corpus théorique dominant en management des systèmes d’information car il s’agit de mettre en lumière les facteurs explicatifs et prédictifs de l’acceptation d’une technologie de l’information donnée (Davis, 1989 ; Venkatesh et al., 2003, 2012; Benbasat et Barki, 2007). L’originalité est ici de s’intéresser aux technologies de télédéclaration fiscale au Maroc c’est-à-dire en contexte socioéconomique émergeant. Les principaux résultats de ce travail doctoral ont confirmé l’hypothèse globale selon laquelle l’intention d’utilisation des TI par les contribuables influence le comportement d’usage de la technologie. Néanmoins, ces résultats sont étoffés par l’importance de certains déterminants moins médiatisés comme l’influence sociale, des conditions de facilitation, de la confiance dans la gouvernance du site web dédié à la télédéclaration, de la performance attendue, de l’effort attendu. L'ensemble de ces facteurs influence la décision d’acceptation puis d'usage de la télédéclaration fiscale pour le contribuable marocain et peuvent être à ce titre des leviers à mobiliser.This doctoral thesis is concerned with the factors influencing the adoption and use of e-government technologies. As positivist epistemological posture, the research is based on a mixed methodology: a qualitative approach based on the Delphi method, followed by a hypothesis test. This thesis aims to highlight the factors that explain and predict the acceptance of information technologies (Davis, 1986, Venkatech et al., 2003, 2012, Benbasat et Barki, 2007) in the tax E-filing systems in Morocco. The results of this thesis have confirmed the overall hypothesis that the intention of taxpayers to use IT influences technology behavior use. Moreover, they have shown that the social influence, the facilitation conditions, the trust in the website governance, the expected performance, as well as the expected effort are the most significant factors predicting the adoption of the IT in the tax E-filing. The present thesis, furthermore, contributes to better understand the adoption behavior of e-government services, among other things through the mobilization of unified theory of acceptance and use of technology (UTAUT) which is improved and completed by the trust theory. Moreover, it suggests many variables actions that can support managerial action in the deployment of tax E-filing projects at the individual, technological and organizational levels
