Observations sur le Frelon asiatique à pattes jaunes, Vespa velutina Lepeletier, 1836 (Hymenoptera, Vespidae)
No full textObservations on the Yellow-Legged Hornet Vespa velutina Lepeletier, 1836 (Hymenoptera, Vespidae). Sampling performed in May 2010 during a trip in Indonesia provided data on the distribution of different varieties of Vespa velutina Lepeletier, 1836, in this archipelago as well as on foraging and hunting behavior of the species. These data contribute to a better understanding of the feeding behavior of this invasive hornet introduced in France before 2004.Les collectes réalisées en mai 2010 lors d'une mission en Indonésie ont permis d'acquérir des données sur la distribution de différentes variétés de Vespa velutina Lepeletier, 1836, présentes sur cet archipel, ainsi que sur le comportement de chasse et de butinage de l'espèce. Ces données aident à une meilleure compréhension du comportement alimentaire de ce frelon invasif introduit en France avant 2004.Perrard Adrien, Muller Franck, Rome Quentin, Villemant Claire.

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

Thorax - 3D
No full textSurface files (.ply) of the mesosoma (~thorax) from the CT-scan 3D models of the 22 specimens. These surface files were used to assess the landmark coordinates to quantify the shape of the mesosoma (~thorax). Raw CT-scan data are not deposited because too large, but can be accessed by contacting the author
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
