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
Can we buffering working conditions? : An analysis through the job demands/resources model
No full textSur leur lieu de travail, les individus sont confrontés à de nombreuses difficultés. Souvent, ces difficultés sont engendrées par de mauvaises conditions de travail qui génèrent des phénomènes de risques psychosociaux (RPS), susceptibles de nuire à la santé des salariés. En Sciences de la Gestion, les RPS sont l’objet d’un intérêt croissant, car ils ont aussi un impact sur la performance et sur la pérennité de l’entreprise. Alors qu’il existe des politiques et des pratiques de gestion des ressource humaines (GRH) mises en place par les entreprises pour faire face à ces risques, une démarche efficace n’est pas encore aboutie. Or, selon le modèle exigences/ressources (Demerouti et al., 2001), il existe des conditions de travail favorables (ressources) qui ont le potentiel de réduire ces risques, et qui font l’objet de ces travaux de recherche. Plus précisément, cette thèse s’interroge sur les représentations des salarié/es quant aux ressources qui ont le plus de potentiel pour réduire les effets des conditions de travail nocives. En même temps, nous faisons l’hypothèse que ces ressources sont aussi capables d’influencer la pérennité de l’entreprise, via la fidélisation des salarié/es. Nous avons mené une étude de cas au sein d’un groupe de l’agro-alimentaire, qui contrôle deux implantations industrielles qui ont conservé leur culture d’entreprise d’avant la fusion dans ce groupe. Nos résultats montrent que les salariés identifient quatre ressources (autonomie au travail, variété des tâches, bon climat social et soutien des supérieurs) qui ont plus de potentiel que d’autres pour compenser les conditions de travail contraignantes, et que ces ressources sont largement citées quel que soit le genre, le poste occupé, et le site. Il apparaît que ces mêmes ressources sont aussi capables d’influencer l’intention de rester des salarié/es dans l’entreprise. Cependant, ce ne sont pas toujours les pratiques de GRH qui créent ces ressources, mais –d’après les représentations des salariés- plutôt des valeurs liées à la culture d’entreprise précédant la fusion. Au-delà de la contribution à la théorie Exigences/Ressources, nos travaux souhaitent aussi contribuer à la prise de conscience, par les managers, de l’intérêt de certaines ressources pour la mise en place de meilleures conditions de travail et l’amélioration des stratégies de pilotage de la pérennité.At the workplace, individuals face many challenges. Usually these difficulties are caused by poor working conditions that generate the phenomena of psychosocial risks factors (PRF), which can harm the health of employees. In management sciences, an increasing interest has set to PRF, particularly because they also have an impact on the performance and on the longevity of the company. The human resource management (HRM) policies and practices are made by companies to deal with these risks, but an effective approach is not yet achieved. According to the job demands / resources model (Demerouti et al., 2001), there are better working conditions (resources) that have the potential to buffer demands which causes PRF. Resources are the subject of this thesis.Precisely, this thesis questions the employees’ representations resources that have the greatest potential to buffer harmful working conditions. At the same time, we make the assumption that these resources are also able to influence the longevity of the firm, through employee loyalty. We conducted a case study within an agri-food group, which controls two industrial establishments which inherited their organizational culture before joining this group. Our results show that employees identify four resources (autonomy at work, task variety, good social climate and superiors support) that have more potential than others to buffer dangerous working conditions. Moreover, these resources are equally quoted in relation to gender, occupation, and industrial site. Furthermore, it appears that the same resources are also able to influence employees intention to remain in the group. However, it is not always the HRM practices that create these resources, but rather the values that are linked to the firm culture, before the merger.Beyond the contribution to the job demands / resources model, our research also aims to contribute to the managers' awareness of the value of certain resources to implement better working conditions and management strategies of longevity
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
