Borneomyia Brake
No full textBorneomyia Brake, n. gen. Genus nov 1, in Brake 2000. Type species: Borneomyia tigra Brake, n. sp., by present designation. Description: Body wholly subshiny, only mesonotum slightly more shiny. Body usually yellow with brown stripes. Antennal grooves yellow with roughly circular spot ventral to each antenna. Head (fig. 1): Frontal triangle extending to level of middle orbital seta. Three orbital setae, posterior seta lateroreclinate, anterior 2 setae lateroclinate; two medioclinate frontal setae. One reclinate setula between posterior and middle orbital setae, one medioclinate setula each between middle and anterior orbital setae and between anterior orbital seta and posterior frontal seta, 2 or 3 medioclinate setulae between frontal setae, and one medioclinate setula ventral to anterior frontal seta; about 5–6 small interfrontal setulae, anterior setula slightly longer; additional setula between anterior interfrontal setula and anterior frontal seta. Lateroproclinate ocellar and medial and lateral vertical setae present, plus some setulae. Postocellar setae cruciate. Lunula not or only narrowly visible, apparently without setulae, merging into face. Antenna short; basoflagellomere round, about as long as pedicel; arista long (about as long as head height), long pubescent. Vibrissal angle not produced, but base of vibrissa protuberant. Vibrissa well developed, followed posteriorly by slightly smaller seta also on slight protuberance. Gena covered by several setulae. Palpus flat, elongate spatulate, with several setulae. Labellum with 4 pseudotracheae, 2 medial pseudotracheae converging towards labellum apex. Thorax: Mesonotum about as long as broad. Chaetotaxy: 1 large postpronotal plus 1 additional seta about 0.4 x length of postpronotal, 2 notopleural, 1 presutural, 1 supraalar, 1 postalar, 1 intraalar, and 3 postsutural dorsocentral setae, anterior dorsocentral only slightly longer than acrostichal setulae, middle dorsocentral about 0.6 x length of posterior dorsocentral, acrostichal setulae in irregular rows, 1 short prescutellar acrostichal seta, 1 apical and 1 basal scutellar setae, basal seta longer than apical seta, apical setae cruciate, 1 proepimeral seta, 1 proepisternal seta, anepisternum bare, 1 katepisternal seta and row of setulae anterior to katepisternal seta from dorsal to ventral margin of katepisternum, no anepimeral seta. Legs: Forefemur bearing posterodorsal, slightly irregular row of about 6 setae, these becoming progressively longer distally. Foretibia with 2 slightly stronger preapical setulae. Basitarsomere of foreleg with anteroventral row of setulae and a few stronger setulae ventrobasally. Midfemur in males with femoral organ anterodorsally and shortly proximal to middle (figs. 2 and 3). Femoral organ consisting of field of irregularlyplaced tiny setulae of probably sensory function (Brake 2000). Midtibia with several stronger setulae and 1 seta preapically. Hindfemur enlarged, about 1.5–1.8 x as broad as fore and midfemur. Hindtibia as foretibia, with ventroapical comb of setulae. Basitarsomere of hindleg with several ventral rows of 3–5 setulae, with setulae flattened apically (fig. 4), and with few stronger setulae ventrobasally. Wing (fig. 8): R 4 + 5 and M 1 parallel. Cell cup closed. Wing surface covered by numerous brown microtrichia which are about as long as costal spines. Abdomen: Tergites with relatively sparse setulae, with setulae progressively longer posteriorly, and row of setae along posterior margins of tergites 4 and 5. Sternite 5 with row of setae, setae posterolaterally longest. Male terminalia as in fig. 7. Epandrium spherical; surstylus deeply notched at middle. Hypandrium Ushaped, not fused with phallapodemic sclerite. Pregonites bare, not fused with hypandrium, but appear to be fused with phallapodemic sclerite. Distiphallus short and glabrous, without sclerotizations. Females differ from males in absence of femoral organ. Sternites 28 complete, not reduced. Ventral receptacle globular; spermathecal ducts elongate and rolled up together distally into one longish spoollike coil; sclerotized spermathecal capsules absent, distal end of spermathecal ducts surrounded by epithelial gland cells. Etymology: The genus name is derived from the island Borneo and the Greek myia = fly, referring to the place where most of the specimens have been collected. The gender of the name is feminine. Discussion: The new genus differs from other milichiid genera in the presence of a femoral organ on the male midfemur, in the basitarsomere of the hindleg having several ventral rows of 3–5 setulae, and in the brown spot, each, on the otherwise yellow antennal grooves.Published as part of Brake, Irina, 2004, Borneomyia, a new genus and two new species of Milichiidae (Diptera, Schizophora), pp. 1-8 in Zootaxa 627 on pages 2-4, DOI: 10.5281/zenodo.15824
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
