Bernard Walliser (dir.), La distinction des savoirs
No full textAvec La distinction des savoirs, ce sont onze chercheurs issus des sciences sociales qui s’attaquent à une même question : celle du rapport entre connaissance savante et connaissance vulgaire. En donnant la parole à une pluralité de disciplines, le groupe de travail réuni autour de l’économiste Bernard Walliser a ainsi fait sienne une double ambition : la première, donner à voir la multiplicité des agencements entre le savant et le vulgaire ; la seconde, identifier la spécificité des sciences..
Equilibres et anticipations
No full text[fre] L'article établit un survey des contributions récentes concernant les anticipations des agents économiques et leur influence sur les équilibres économiques, à l'exclusion du problème des tests empiriques des schémas d'anticipation et de l'analyse des conséquences de politique économique des modèles étudiés. La possibilité de coïncidence entre variables endogènes anticipées et réalisées a été explorée aussi bien dans le champ macroéconomique (anticipations rationnelles), microéconomique (prévisions parfaites) et socio-économique (prophéties auto-réalisatrices) et conduit à des solutions multiples pouvant être engendrées par des modèles d'anticipation alternatifs, également confirmés à l'équilibre. Les types d'équilibre résultant d'anticipations croisées entre agents à plusieurs niveaux ont aussi été formalisés dans le cadre de la théorie du duopole et les conditions de convergence des processus d'apprentissage des agents sur leurs modèles d'anticipation sont progressivement dégagées. [eng] Equilibria and expectation. Bernard Walliser. This article makes a survey of recent contributions concerning economic expectations and their influence on economic equilibria, excluding the problem of empirical tests of expectation schemes and analysis of economic policy effects of the models on elimination. The possibility of identification between expected and achieved endogeneous variables tous explored simultaneously in the field of macro-economics (rational expectations), microeconomics (perfect foresights) and socio-economics (self-fulfilling profhecies), and leads to multiple solutions being obtained by alternative expectation models, identically confirmed at equilibrium. The types of equilibria resulting from multi-level crossed expectations between agents were also formalized in the context of duopoly theory and convergence conditions of learning processes on agents expectation models are progressively worked out.

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
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
