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
Oryctes corniculatus A. Villa & G. B. Villa 1833
No full textOryctes corniculatus A. Villa & G. B. Villa, 1833 Oryctes corniculatus A. Villa & G. B. Villa, 1833: 34. Two syntypes are deposited in NMPC (ex coll. Nickerl): SYNTYPE (J): ‘ Oryctes corniculatus Villa typ, Mediolani 1837 [hw]’. SYNTYPE (♀): ‘ Oryctes corniculatus Med. Villa [hw, white label, red margin] // Villa typ Mediolan [hw, white label, black margin] // O. corniculatus 1837 Villa typ [hw]’. Current status. Oryctes nasicornis corniculatus A. Villa & G. B. Villa, 1833, see, KRELL (2002). Remark. A major part of A. Villa’s collection is in bad condition and deposited in Museo Civico di Storia Naturale Milano (HORN et al. 1990). Unfortunately, we were not able to compare our specimens with that material. As we have no reason to doubt Nickerls’ designation, we consider the specimens mentioned above to be true syntypes. The date ‘1837’ refers, according to us, to the year when the specimens were incorporated into Nickerl’s collection rather than to the date of collecting.Published as part of Bezděk, Aleš, Hájek, Jiří & Ascr, Biology Centre, 2010, Catalogue of type specimens of beetles (Coleoptera) deposited in the National Museum, Prague, Czech Republic, pp. 279-320 in Acta Entomologica Musei Nationalis Pragae 50 (1) on pages 282-283, DOI: 10.5281/zenodo.532573

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
