Les Elatérides forestiers français : une approche écologique en Seine-et-Marne (Coleoptera, Elateridae)
No full textContribution to the knowledge of French forest-dwelling click beetles : an ecological approach in Seine-et-Marne (Coleoptera, Elateridae). The species assemblages of forest-dwelling click beetles were studied in several forest habitats in the Ferrières, Armainvilliers and Crécy forests. Ecological, phenological and faunistic comments concern the 25 species sampled during the study. The diversity of the regional Ferrières forest is peculiarly important. Among the rarest taxa, Hypoganus inunctus (Panzer), Paraphotistus nigricornis (Panzer) and Anostirus castaneus (L.) may be mentioned. Due to the high number of uncommon species and the high cumulative species richness in forest openings (windthrow gaps, cutting areas…), their role in the maintenance of forest biodiversity is underlined.Les assemblages d’Elateridae sylvicoles ont été étudiés dans différents types de milieux forestiers des massifs de Ferrières, Armainvilliers et Crécy-en-Brie (77). L’écologie, la phénologie et l’intérêt faunistique des 25 espèces capturées sont commentés. Parmi les taxons les moins communs, citons Hypoganus inunctus (Panzer), Paraphotistus nigricornis (Panzer) et Anostirus castaneus (L.). En raison de la présence de plusieurs espèces rares et d’une forte richesse spécifique cumulée, l’intérêt des milieux ouverts intra-forestiers (trouées de chablis ou coupes) pour la biodiversité forestière est discuté. La diversité faunistique de la forêt régionale de Ferrières est soulignée.Bouget Christophe, Chassain Jacques.

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
