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
Conception d'une plate-forme de services ubiquitaires intégrant des interfaces multimodales distribuées
No full textWeb-Based Information Technologies & Distributed Systems represent a powerful shift in computation, where people live, work, and play in a seamlessly interweaving computing environment. It postulates a world where people are surrounded by computing devices and a computing infrastructure that supports us in everything we do. Current means of interactions with applications are almost exclusively the keyboard and the mouse or emulations thereof. This kind of interface is well adapted for classic management of information, but the new usages, mobility, ubiquitous access to information need new interfaces and new interaction modes. This thesis aims to modelize and develop a distributed software platform allowing the user access to ubiquitous services through distributed interfaces in these new usage contexts. We propose the original architecture model UbiArch. This system extends the user interface in order to allow several modes of interactions, offering users the choice of using their voice thanks to headset or phone, or an input device such as a keypad, keyboard or other input device. For output, users will be able to listen to audio devices, and to view information on graphical displays such as phones, PDA or TV screen or by using a projector. This concept is called ``distributed modality''. The 3-tiers design of the mVIP services based on UbiArch offers a framework in order to implement multimodal services for many application contexts. Here, we have described the use of our technology in a biometric authentication context, in a multimodal cash point simulator and in a slide show application controlled from a vocal and DTMF remote phone. This thesis has shown the feasibility of such an architecture dealing with many components and protocols.Les technologies web ont permis de définir des services accessibles par tous, n'importe où et depuis de multiples terminaux. Si les utilisateurs intègrent maintenant l'usage des interfaces graphiques traditionnelles, la miniaturisation des équipements et l'émergence de nouvelles modalités offrent de nouvelles perspectives en matière d'informatique ubiquitaire. Dans ce mémoire, nous modélisons l'interaction ubiquitaire selon les principes fondamentaux des modèles de la littérature. Nous proposons une implémentation de notre modèle UbiArch sous forme d'une plate-forme de services et nous mettons à la disposition du concepteur d'applications web un ensemble d'outils interactifs, prêts à être intégrés dans des interfaces web. Nous illustrons les principes de notre modèle et le fonctionnement de notre plate-forme au travers de trois démonstrateurs. Chacune de ces réalisations intègre les capacités d'interaction des téléphones dans une application web et illustre les apports de notre travail en terme d'interaction multimodale distribuée

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
