Drosophila dacunhai Mourao & Bicudo 1967
No full textDrosophila dacunhai Mourão & Bicudo, 1967 (Fig. 10) Non-type material. Strain DAC (Petionville, Haiti): 80 males dissected. Male terminalia. The structure that most differs in D. dacunhai is the ventral postgonite (Fig. 10A–C). This structure has pointed scales and a groove in its upper portion; besides, it is longer and slightly curved (Fig. 10B, C). In addition, the aedeagal apex is the most flattened and largest (Fig. 10B, C).Published as part of Roman, Bruna Emilia & Madi-Ravazzi, Lilian, 2021, Male terminalia morphology of sixteen species of the Drosophila saltans group Sturtevant (Diptera, Drosophilidae), pp. 523-544 in Zootaxa 5061 (3) on page 534, DOI: 10.11646/zootaxa.5061.3.7, http://zenodo.org/record/564995

Drosophila lehrmanae Madi-Ravazzi 2021
No full textDrosophila lehrmanae Madi-Ravazzi et al., 2021 (Fig. 9) Non-type material. Strain STV-like (Camp Nouragues, French Guiana): 80 males dissected. Male terminalia. The aedeagus of this species is very similar to that of D. sturtevanti (Fig. 9A–C), however, the striking characteristic that differs it from the other species is the relatively short aedeagal apex (Fig. 9B, C). In addition to this, the lower base of the aedeagus has a less pronounced projection than that of D. sturtevanti (Fig. 9B).Published as part of Roman, Bruna Emilia & Madi-Ravazzi, Lilian, 2021, Male terminalia morphology of sixteen species of the Drosophila saltans group Sturtevant (Diptera, Drosophilidae), pp. 523-544 in Zootaxa 5061 (3) on page 534, DOI: 10.11646/zootaxa.5061.3.7, http://zenodo.org/record/564995
Drosophila pseudosaltans Magalhaes 1956
No full textDrosophila pseudosaltans Magalhães, 1956 (Fig. 7) Non-type material. Strain PSE (Cantareira, São Paulo, Brazil): 61 males dissected. Male terminalia. The hypandrium, the aedeagal sheath, aedeagal apex, aedeagal ventral processes and pregonites of this species resemble those of D. nigrosaltans (Fig. 7A–E). The aedeagal dorsal crest is lower in D. pseudosaltans (Fig. 7B). The most notable difference between these species is in the ventral postgonites with wider, darker, and slightly bifurcate ends in D. pseudosaltans (Fig. 7B–D).Published as part of Roman, Bruna Emilia & Madi-Ravazzi, Lilian, 2021, Male terminalia morphology of sixteen species of the Drosophila saltans group Sturtevant (Diptera, Drosophilidae), pp. 523-544 in Zootaxa 5061 (3) on page 532, DOI: 10.11646/zootaxa.5061.3.7, http://zenodo.org/record/564995
Drosophila lusaltans Magalhaes 1962
No full textDrosophila lusaltans Magalhães, 1962 (Fig. 3) Non-type material. Strain B 44 (Petionville, Haiti): 20 males dissected. Male terminalia. The hypandrium presents rounded and convergent median gonocoxites, with a divergent median hypandrial bristle at the end of each side (Fig. 3A, D). The aedeagal apex (Fig. 3A–D) is very similar to that of D. saltans, it also has bristles; however, this species displays an apical groove that isolates two lateral protuberances on the aedeagal apex (Fig. 3B). The aedeagal sheath is smooth, with a serrated edge and it presents a tuft of bristles in the dorsal region (Fig. 3B, C). The aedeagal ventral processes, ventral postgonites and pregonites are very similar to D. saltans (Fig. 3B, C).Published as part of Roman, Bruna Emilia & Madi-Ravazzi, Lilian, 2021, Male terminalia morphology of sixteen species of the Drosophila saltans group Sturtevant (Diptera, Drosophilidae), pp. 523-544 in Zootaxa 5061 (3) on page 527, DOI: 10.11646/zootaxa.5061.3.7, http://zenodo.org/record/564995
Drosophila sturtevanti Duda 1927
No full textDrosophila sturtevanti Duda, 1927 (Fig. 8) Non-type material. Strains STV-1 (Matão, São Paulo, Brazil): 47 males dissected; STV-2 (Aguaí, Santa Catarina, Brazil): 14 males dissected; and STV-3 (Ribeirão da Ilha, Santa Catarina, Brazil): 10 males dissected. Male terminalia. The aedeagal apex resembles a horn, where the phallotrema is found (Fig. 8A–C). The ventral postgonite is chitinized, rigid and smooth and the base of this structure together with the upper ventral region of the aedeagus have scales (Fig. 8B, C). The lower base of the aedeagus displays a “caudal” projection (Fig. 8B).Published as part of Roman, Bruna Emilia & Madi-Ravazzi, Lilian, 2021, Male terminalia morphology of sixteen species of the Drosophila saltans group Sturtevant (Diptera, Drosophilidae), pp. 523-544 in Zootaxa 5061 (3) on page 533, DOI: 10.11646/zootaxa.5061.3.7, http://zenodo.org/record/564995
Drosophila milleri Magalhaes 1962
No full textDrosophila milleri Magalhães, 1962 (Fig. 11) Non-type material. Strains MI-1 (El Yunque, Puerto Rico): 24 males dissected; and MI-2 (French Guiana): 12 males dissected. Male terminalia. The aedeagus is more similar to D. dacunhai, as it also presents pointed scales on the ventral postgonite, in addition to a groove in the upper part of it (Fig. 11A–C). The striking characteristic is that the ventral postgonite is wider than the other species in the subgroup (Fig. 11B).Published as part of Roman, Bruna Emilia & Madi-Ravazzi, Lilian, 2021, Male terminalia morphology of sixteen species of the Drosophila saltans group Sturtevant (Diptera, Drosophilidae), pp. 523-544 in Zootaxa 5061 (3) on page 535, DOI: 10.11646/zootaxa.5061.3.7, http://zenodo.org/record/564995
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
