LERU Bruno/G169-G377). TANZANIA: 1 ♂, Iringa region, Sao Hill, 08°27.421' S, 35°10.036' E, 1845 m a.s.l., 22 Jan. 2012, ex larva (in stem of Hyparrhenia sp.), B. Le Ru leg. (MNHN); 3 ♂♂, same locality, Nov. 2015, ex light trap, B. Le Ru leg. (MNHN, gen. prep. LERU Bruno/G937). Description Only the male is known (Fig. 6A–B); antennae cupreous brown dorsally and ochreous ventrally, slightly ciliate; fagellum adorned dorsally with white scales, palpus cupreous brown, adorned with white scales, eyes fuscous. Head and base of thorax brown, thorax becoming gradually ochreous; legs brown-ringed with white; abdomen brown irrorated with fuscous scales, extremity of abdomen densely suffused with buff scales. FORE WING. Ground colour dark ochreous, suffused with fuscous and brown scales, more heavily along veins and in costal area; reniform indicated by few white scales, preceded by some brown scales; longitudinal brown median fascia along lower external margin of cell, ending obliquely at apex; veins below cell adorned with white, fuscous and brown scales; postmedial row of white spots on veins; row of black elongated spots between veins on margin; fringe whitish externally, ochreous suffused with brown internally. Underside of fore wing with ground colour brown, suffused with fuscous scales on costa. HIND WING. Uniformly brown; fringe white suffused with fuscous and adorned with narrow fuscous line. Underside of hind wing brown, suffused with fuscous scales. WINGSPAN. 21–23 mm (4 ♂♂). MALE GENITALIA (Fig. 2C, K). Uncus long, widening in distal third, truncated at apex, tufted with long hairs on upper side. Tegumen with medium-sized rounded penniculi, vinculum pointed, with mediumsized triangular saccus, valves short and broad, cucullus spoon-shaped and tufted with medium size hairs, coastal margin slightly broadened on inner side and produced into narrow, straight, long lobe, roundly pointed; juxta oblong, pear-shaped, with long and wide neck, elongate bifd. Aedeagus short, slightly curved, with two lateral areas adorned with short setae; turn of hand-shaped vesica with large tuft of needle-shaped cornutus. Bionomics One larva was collected at the bottom of a stem of a Hyparrhenia sp. growing in grasslands near marshes (Table 3); like many species of Acrapex, A. kavumba sp. nov. is a markedly hygrophilous species. Unfortunately, no pictures were taken before pupation. All the moths were caught in a light trap in grasslands near marshes. Distribution Tanzania and Zambia. The records are from a mosaic of Zambezian dry evergreen forest and wetter miombo woodland (Mosaic #21) (White 1983) (Fig. 4), belonging to the Zambezian bioregion (Linder et al. 2012) (Fig. 5).Published as part of Bruno Le Ru, Claire Capdevielle-Dulac, Boaz K.

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
