Female (Paratype). Differs from male in perimarginal ridges of clypeus being trapeziform in shape. Etymology. The name B. bilaspuricans refers to the Bilaspur district in the state of Chhattisgarh, India. Historical records explain that Bilaspur was named after a fisherwoman by the name of “Bilasa” in the 17 th century. Distribution (Figs. 11–12). Only known from the type locality. Differential diagnosis. Bolboceras bilaspuricans is characterized mainly by the unique structure of the aedeagus (Figs. 8–10). The species in the B. nigricans group can be separated into two groups on the basis of perimarginal ridges of male clypeus being either K shaped or X shaped. The species with X shaped perimarginal ridges of clypeus are, Bolboceras extraneum Krikken, 2013 and B. insulare Krikken, 2013. Whereas, the species with K shaped perimarginal ridges of clypeus are; B. mimicans Krikken, 2013, B. nigricans Westwood, 1848, B. schulzei Krikken, 2013, and B. malabaricum Krikken, 2013. In, B. mimicans and B. nigricans, the pronotal discomedian impression are deep whereas in B. schulzei and B. malabaricum, the pronotal discomedian impression are shallow or almost effaced. The new species, B. bilaspuricans, possess a K-shaped perimarginal ridges with the pronotal discomedian impression shallow. Structurally, B. bilaspuricans, resembles B. malabaricum and B. schulzei. In B. bilaspuricans, the paramere tip is subangular, the basal genitalic capsule of male not broad, the crest of interocular elevation not tuberculate, and the height of the interocular elevation on the frons is low; whereas in. B. malabaricum, the parameral tip is acuminate, the basal genitalic capsule of male smaller, the crest of interocular elevation tuberculate (medially slightly raised), and the height of interocular elevation on the frons is high. Bolboceras bilaspuricans is also similar to B. schulzei, but the aedeagus has a different shape. In B. bilaspuricans, the aedeagal lateral stalks have hooked, recurved tips while in B. schulzei, the aedeagal stalks have slightly tapering tip that are not hooked. For details, see also the diagnostic character list for this species group (Table 1).Published as part of Gupta, Devanshu & Chandra, Kailash, 2016, Bolboceras bilaspuricans (Coleoptera: Geotrupidae: Bolboceratinae), a new species from Chhattisgarh, India, pp. 295-300 in Zootaxa 4103 (3) on pages 296-300, DOI: 10.11646/zootaxa.4103.3.9, http://zenodo.org/record/26551
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
