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

Etymology. The specific epithet “ quetzali ” derives from the common name of the type host, which is the national bird of Guatemala. Type material. Female holotype, 12 female and 2 male paratypes from secondary covert quill of Pharomachrus mocinno Llave (Trogoniformes: Trogonidae); GUATEMALA, no other data. Host specimen deposited in ZSM (Reg. no. ZSM 81 / 13). Type deposition. Holotype and most part of paratypes deposited in AMU, except 2 female paratypes in ZISP, and 2 female paratypes in ZSM. Additional material. Four females and 2 males from secondary covert quill of Pharomachrus antisianus (Orbigny); ECUADOR, 20 July 1961, no other data. Host specimen deposited in the ZSM (Reg. no. ZSM 64 / 515). All mite material is deposited in AMU, except 1 female and 1 male in ZSM. Differential diagnosis. Syringophiloidus quetzali sp. nov. belongs to the group “ glandarii ” and is closely related to S. molothrus Skoracki, Flanery and Spicer, 2009 described from Molothrus ater (Boddaert) (Passeriformes: Icteridae) in the United States (Skoracki et al. 2009). In females of both species, the hysteronotal shield is not fused to the pygidial shield; the genital plate is present; the propodonotal shield is apunctate; each medial branch of the peritremes has 2–3 chambers; setae ve and si are longer than vi, and setae ps 1 and ps 2 are subequal in length. This new species is distinguished from S. molothrus by the following characters: in females of S. quetzali, the propodonotal shield is weakly sclerotized and striae are visible; the length ratio of setae vi: ve is 1: 2.2–2.4; the pygidial shield is densely punctate; setae d 2 are slightly (1.2 times) longer than e 2, and fan-like setae p’ and p” of legs III and IV have 10 tines. In females of S. molothrus, the propodonotal shield is well sclerotized and striae are indiscernible; the length ratio of setae vi: ve is 1: 2.8; the pygidial shield is sparsely punctate; setae d 2 are 1.5 times longer than e 2, and fan-like setae p’ and p” of legs III and IV have 7–8 tines. Genus Syringophilopsis Kethley Mites of this genus inhabit feather quills of primaries and secondaries, and up to now they have been reported from two host orders, Passeriformes and Coraciiformes (Skoracki et al. 2012).Published as part of Skoracki, Maciej, Mironov, Sergey V. & Unsoeld, Markus, 2013, The first records of quill mites of the family Syringophilidae (Acariformes: Prostigmata: Cheyletoidea) from trogoniform birds (Aves: Trogoniformes), pp. 291-297 in Zootaxa 3701 (2) on pages 292-294, DOI: 10.11646/zootaxa.3701.2.9, http://zenodo.org/record/22419
