Glypturus lanceolatus. — Sakai 1999: 83.— Sakai 2005: 142.— Sakai 2011: 435. Corallianassa lanceolata.— Komai et al. 2015: 15, 18, 51–54. Material examined. USA, Hawaii, Northwestern Hawaiian Islands, Pearl and Hermes Reef, T. T. Dranga, April 1927, BPBM S2735 (2 specimens). Diagnosis. Rostrum upturned; carapace anterolateral spines triangular, short. Maxilliped 3 ischium-merus 2.5 times as long as wide; merus mesiodistal margin convex; propodus, free distal margin transverse. Major cheliped ischium lower margin with 2 small distal spines; merus lower margin with row of diminishing denticles; palm as long as wide. Minor cheliped merus lower margin smooth; palm 1.3 times as long as wide, rectangular; fingers as long as palm, curved. Uropodal endopod 3 times as long as wide; anterior margin sinuous; posterior margin convex; apex attenuated. Uropodal exopod posterior margin strongly concave in adult. Telson slightly tapering, 1.7 times as wide as long; posterior margin with medial lobe more prominent than posterolateral corners; dorsal surface with about 6 pairs of fine setae separated by median gap on transverse ridge. Size. Cl. to 9 mm. Distribution. USA, Hawaii: Oahu, Pearl and Hermes Reef (type locality: Hanauma Bay) Remarks. Corallianassa lanceolata resembles C. assimilis (De Man, 1928) from Indonesia and Guam but has a more attenuated uropodal endopod. Komai et al. (2015) noted that Callianassa (Callichirus) nakasonei Sakai, 1967, synonymised with this species by Sakai’s (2011), is instead a synonym of Corallianassa martensi.Published as part of Poore, Gary C.

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

Paulay, 27 May 2017, UF 45530 (ovigerous female, 9.7 mm). Diagnosis. Rostrum upturned; carapace anterolateral spines with mesial buttress. Maxilliped 3 ischium-merus 2.4 times as long as wide; merus tapering; propodus, free distal margin transverse. Major cheliped ischium lower margin with 8–10 oblique spines increasing in length distally; merus lower margin with 4–8 small oblique spines; palm as long as wide, upper margin carinate along more than proximal half and along distal quarter. Minor cheliped merus lower margin with 2 or 3 oblique spines; palm 1.3 times as long as wide, rectangular; fingers as long as palm, curved. Uropodal endopod 2 times as long as wide; anterior margin slightly convex; posterior margin convex; apex broadly rounded, flat. Uropodal exopod posterior margin slightly concave; proximal article with sharp spine overlapping endopod and smaller accessory proximal lobe. Telson tapering to about two-thirds basal width from basal lobes, 1.7 times as wide as long; posterior margin with medial lobe more prominent than posterolateral corners; dorsal surface with about 6 pairs of fine setae in row on transverse ridge. Size. Cl. to 12 mm. Colour. Carapace with paired orange anterodorsal patches; remainder of carapace, pleon white. Antennular peduncle article 3 orange; flagella orange-red. Antennal peduncle articles with orange patches; flagellum orangered. Maxilliped 3 with patches of orange. Cheliped meri, carpi with orange patches concentrated on upper margin; propodi mostly orange, with white patch at midpoint; fingers orange. Pereopods 2, 3 with orange patches on upper margins of carpus, propodus. Pereopods 4, 5 white (Fig. 7a, b). Distribution. USA, Hawaii, Oahu (type locality: Hanauma Bay) Remarks. The holotype of Callianassa (Callichirus) oahuensis Edmondson, 1944 (BPBM S4594) was examined by KL and compared with Edmondson’s (1944) figures and those of UF 45530. The holotype plus the material listed above differ from C. borradailei in the discontinuous low carina along the upper margin of the major cheliped palm (flange-like in C. borradailei), the relatively shorter and more tapered telson (1.7 vs 1.5 times wide as long), the absence of middorsal spiniform setae on the telson (3 or 4 pairs present), the upturned rostrum (horizontal) and the narrower maxilliped 3 (ischium-merus 2.4 vs 1.8 times as long as wide) with a more tapered merus. Callianassa (Callichirus) oahuensis Edmondson, 1944 has only ever been treated as a synonym of Corallianassa borradailei (Manning 1987, Komai et al. 2015). Here, we recognise it as an accepted species of Corallianassa.Published as part of Poore, Gary C.

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
