Les récents développements de la modélisation par équations structurelles (SEM) : Cas de la régression des moindres carrés partiels (PLS)
Get PDFLa régression des moindres carrés partiels (PLS) a historiquement démontré son efficacité dans les sciences de gestion. Plusieurs chercheurs font appel à cette méthode confirmatoire dans leurs études empiriques. Les étapes de la modélisation par équations structurelle de type PLS sont largement documentés dans la littérature managériale. Récemment, la méthode PLS a connu plusieurs développements théoriques et méthodologiques dans le modèle de mesure et le modèle structurel. L’objectif de cet article est d’examiner les nouvelles avancées de la régression des moindres carrés partiels (PLS)
La réputation des entreprises : conceptualisation, dimensions et antécédents
Get PDFLa réputation des entreprises a créé un débat dans la recherche en sciences de gestion. Au fil des années, plusieurs travaux de recherche ont tenté de conceptualiser la réputation des entreprises à travers différentes approches théoriques et/ou empiriques. D’une part, selon une optique stratégique, l’entreprise est au centre des échanges entre une multitude de parties prenantes telles que les clients, les fournisseurs, les salariés, les médias, les investisseurs, le grand public etc. De ce fait, certains auteurs avancent l’idée selon laquelle la réputation est composée de plusieurs dimensions. D’autre part, la présence des différentes parties prenantes qui interagissent avec l’entreprise, permet de relever une diversité de concepts qui ont une influence sur la réputation des entreprises. En mobilisant une revue de littérature issue de différents contextes, cet article permet de dresser une vision globale sur les principaux travaux de recherche ayant traité la réputation des entreprises, ses dimensions ainsi que ses antécédents
Le management stratégique au service de la stratégie réputationnelle de l’entreprise
Get PDFLa réputation constitue un pilier sur lequel l’entreprise moderne s’appuie. Cette dépendance est le résultat de l’intensification des exigences des partenaires de l’entreprise qui sont de plus en plus soucieux dans leurs choix. Une réputation est un construit où s’entremêlent un ensemble de variables qui diffèrent d’une entreprise à une autre selon plusieurs critères. Ainsi, l’entreprise utilise toutes ses ressources afin de ressortir avec une valeur ajoutée en terme réputationnel et par conséquent satisfaire toutes ses parties prenantes. De ce fait, les entreprises cherchent à maximiser leurs réputations à l’égard de leurs partenaires, directs ou indirects afin de gérer le risque de réputation. Cette maximisation passe nécessairement par un processus bien établi par l’entreprise au niveau stratégique qui combinera l’ensemble de ses ressources dans une démarche multidimensionnelle adaptée. Dans ce papier, nous nous efforcerons de présenter les processus stratégiques adaptés pour la création d’une valeur ajoutée réputationnelle à l’entreprise
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
