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
Guerre en Ukraine : les États-Unis en perte de pouvoir structurel
No full textAvec le récent sommet des BRICS, les questions monétaires apparaissent à nouveau en haut de l’agenda politique international. Le risque de subir une exclusion des circuits de paiement internationaux suscite en effet une vive inquiétude dans de nombreux pays. Néanmoins, les sanctions économiques sont une arme à double tranchant. Elles peuvent affaiblir le pays visé mais elles peuvent aussi encourager une réorganisation de l’économie mondiale permettant d’éviter les effets néfastes des sanctions et débouchant sur une modification du jeu des alliances internationales

L’économie politique de l’accès technique au marché : le cas du TAFTA
No full textInternational audienceThe thesis demonstrates the contentious nature of technical market access. Within the frame of deep integration liberalization, the removal of technical barriers to trade is central. It proceeds through the convergence of technical infrastructures (technical standards and regulations, conformity assessment). Based on an interdisciplinary approach and mixed-method research, the thesis studies the case of the Transatlantic Trade and Investment Partnership (TTIP/formerly TAFTA [Transatlantic Free Trade Area]) negotiations between the EU and the USA (2013-2016). It shows that technical market access talks constitute an institutionalized field of pre-market competition on which actors, situated at different spatial scales, rival in order to secure competitive advantage. The failure of the negotiations stems above all from each party’s attempt to unidirectionally extend its technical infrastructure to the other side of the Atlantic.La thèse met en évidence la nature conflictuelle de l’accès technique au marché. Dans le cadre de la libéralisation par l’intégration en profondeur, la suppression des obstacles techniques au commerce est centrale. Elle s’effectue par le biais de la convergence des infrastructures techniques (normes et réglementations techniques, évaluation de la conformité). À l’aide d’une démarche interdisciplinaire et de méthodes mixtes, qualitatives et quantitatives, la thèse étudie le cas des négociations poursuivies dans le cadre du Partenariat transatlantique de commerce et d’investissement (PTCI/en anglais TTIP, anciennement TAFTA [Transatlantic Free Trade Area]) entre l’UE et les États-Unis (2013-2016). Elle montre que les négociations entourant l’accès technique au marché constituent un terrain institutionnalisé de compétition pré-marché sur lequel des acteurs, situés à des échelles spatiales différentes, rivalisent pour s’assurer des avantages compétitifs. L’échec des négociations s’explique avant tout par la tentative de chaque partie d’étendre son infrastructure technique de l’autre côté de l’Atlantique
