Hybridization of the Airbus Helicopters training system : individual and organizational learning stakes
No full textL’objet de cette recherche porte sur l’évolution des dispositifs de formation avec l’introduction de technologies de réalité virtuelle dans des contextes industrialisés. Cette thèse Cifre s’appuie sur une intégration au sein du département « training » d’Airbus Helicopters. La démarche de recherche-action mise en œuvre permet d’observer et de participer à l’élaboration d’une technologie immersive pour la formation de pilotes. Cet outil est mis en situation avec des clients en formation et plusieurs démonstrations sont faites auprès d’acteurs de différents métiers. Nous mettons en avant des configurations hybrides dans le sens ou les situations de formation révèlent des aspects de la pratique et de la théorie telles qu’elles sont pensées dans la « langue de l’organisation ». Nous montrons alors que la mise en œuvre de telles technologies pourrait remettre en question les modèles rationalisés dans l’organisation. Ces éléments nous permettent d’envisager qu’une « approche par l’hybridation des dispositifs » amène l’organisation à interroger à chaque étape du projet ses propres modèles (objets structurés de partage d’information, organigramme, compétences et métiers des acteurs). C’est alors une remise en question en « profondeur » du projet de l’organisation apprenante qui est rendue possible, à partir de l’expérience des sujets.The purpose of this research is to better understand how training devices evolve, with the introduction of virtual reality technology, in industrialized training situations. This work I based on an immersion in the "training" department of Airbus Helicopters. The research-action approach allows us to observe and participate in the emergence of a technology of reality for pilot’s training. The tool is put in situation with customers as part of their training and several demonstrations are made to actors of different trades around the training. We identify hybrid configurations in the sense that training situations are both practical and at the same time theoretical in the language of the organization. Then we show that the implementation of these technologies requires to rethink a traditional rationalization. These elements allow to suggest an "approach by the hybridization of systems" gives the organization the ability to reconsider its own project (structured objects of information, organization chart, skills and trades of actors). It is a depth questioning of the learning organization that is possible, from the experience of subjects

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
Hybrider les représentations pour innover dans une organisation
No full textDans cet article, nous proposons d’interroger le rôle des représentations dans la conception et le déploiement d’un dispositif numérique de formation. Plus précisément, nous nous intéressons, d’une part, à une forme de « langue de l’organisation », c’est-à-dire à l’indexicalité (Coulon, 2007) du langage employé dans une organisation et au sein d’une culture professionnelle, et d’autre part, les cadres structurants (les process, les formalismes des documents, l’organigramme) qui conditionnent les représentations des individus. Notre terrain est constitué par un ensemble de travaux menés au sein d’un fabricant d’hélicoptères dans le cadre d’une thèse CIFRE et d’un appel à projets européen de conception d’un dispositif de formation d’opérateurs (pilotes et techniciens de maintenance)
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
