Hypogena triceratops Steiner 2005
No full textHypogena triceratops Steiner, 2005 (Figs 35) Note: This species was recently described and the original description is sufficient to identify specimens to species (Steiner, 2005). Material examined: (2 males): BRAZIL: Mato Grosso: 1 male. TB# 20882 (ADSC). Diagnosis: The clypeal horn is long and thinnest at the base, widening apically and tapering at the apex and without an apical emargination. The supraorbital horns are long and strongly curved inward and forward. The horns of this species are very similar to those of H. dejeani, but this species has thicker supraorbital horns and no emargination at the apex of the clypeal horn. The mentum of this species is also medially and longitudinally bent and the metafemur is weakly bent (Fig. 35).Published as part of Grey, Luna & Smith, Aaron D., 2020, A matrix-based revision of the genus Hypogena Dejean, 1834 (Coleoptera Tenebrionidae), pp. 201-258 in Zootaxa 4780 (2) on page 249, DOI: 10.11646/zootaxa.4780.2.1, http://zenodo.org/record/384236

Note: This species was recently described and the original description is sufficient to identify specimens to species (Steiner, 2005). See Fig. 19 for images of holotype and Fig. 20 for distribution. Material examined: (2 females, 6 males): MEXICO: 1 female. TB# 20206 (NHMB). MEXICO: Veracruz: 1 male. TB# 20203 (EMEC). PANAMA: 2 males. TB# 20878 (CASC); TB# 20205 (BMNH). country not specified: 1 female, 2 males. TB# 19605, 20207, 20884 (BMNH). Diagnosis: The clypeal horn is long and thinnest at the base and widens apically and is truncated at the apex with an emargination. The supraorbital horns are long, thin and strongly bent forward. The horns of this species are similar to those in H. dejeani, but this species can be distinguished by having some large pronotal punctures on the lateral portions of the pronotum and the clypeal horns are not as thick as those in H. dejeani (Fig. 19).Published as part of Grey, Luna & Smith, Aaron D., 2020, A matrix-based revision of the genus Hypogena Dejean, 1834 (Coleoptera Tenebrionidae), pp. 201-258 in Zootaxa 4780 (2) on pages 229-230, DOI: 10.11646/zootaxa.4780.2.1, http://zenodo.org/record/384236
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
