    État de l'art du WebRTC en 2019 et son utilisation au quotidien dans RENdez-vous un service de Visioconférence à l'échelle nationale

    No full text
    At the end of 2010, discussions began on WebRTC, a real-time communication protocol in the browser.Very quickly, Google makes its version of WebRTC accessible to all users of its browser. A complete, efficient and free implementation. This technology is now accessible to a large number of developers and many new videoconferencing solutions emerge.In 2015, RENATER offers RENdez-vous, a new WebRTC-compatible service. This service for Higher Education and Research is based on Jitsi-Meet, an open-source video conference project.Nine years after work began on the WebRTC standard, version 1.0 of the API browser has still not been finalised. The various RFCs supplying the protocols used by WebRTC solutions are still mostly in draft stage.However, WebRTC is now omnipresent in all video conferencing devices and solutions. After four years of using RENdez-vous, we offer our feedback on the use of WebRTC.This experience allows us to take stock of the real situation of WebRTC in 2019. In particular, we describe how the various changes to this standard and its implementations impact the Jitsi-Meet project and our department. Jitsi-Meet offers a very comprehensive solution with a large community of developers. This project is very responsive to the different changes in WebRTC in the main browsers. However, there is a certain complexity in its architecture and its developments. Lastly, we propose a discussion on what the next version of WebRTC may involve in terms of development of videoconferencing services and on RENdez-vous.Fin 2010 commence les réflexions sur le WebRTC, un protocole de communication temps réel dans le navigateur.Très rapidement, Google rend accessibles à tous les utilisateurs de son navigateur sa version du WebRTC. Une implémentation complète, performante et gratuite. Cette technologie est alors accessible à un grand nombre de développeurs et bon nombre de nouvelles solutions de visioconférence vont émerger.En 2015, RENATER propose RENdez-vous un nouveau service compatible WebRTC. Ce service à destination de l’ESR se base sur Jitsi-Meet un projet opensource de visioconférence.Neuf ans après le début des travaux sur la norme WebRTC, la version 1.0 des API navigateur n’est toujours pas finalisée. Les différentes RFC détaillants les protocoles utilisés par les solutions WebRTC sont toujours majoritairement à l’état de Draft.Le WebRTC est néanmoins aujourd’hui omniprésent dans tous les appareils et les solutions de visioconférence. Après quatre années d’exploitation de RENdez-vous, nous proposons notre retour d’expérience sur l’utilisation du WebRTC.Cette expérience nous permet de faire un point sur la situation réelle du WebRTC en 2019. Nous exposons en particulier comment les différentes évolutions de cette norme et de ses implémentations impactent le projet Jitsi-Meet et notre service. Jitsi-Meet offre une solution très complète avec une grande communauté de développeurs. Ce projet est très réactif aux différents changements du WebRTC dans les principaux navigateurs. Cependant, il présente une certaine complexité dans son architecture et ses évolutions. Nous proposons enfin, une réflexion sur ce que la prochaine version du WebRTC pourra impliquer sur l’évolution des services de visioconférence et sur RENdez-vous

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 PDF
    We 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 PDF
    We 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 text
    We 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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
