Apterichtus klazingai
No full text[[Apterichtus klazingai (Weber)]] Record of Apterichtus klazingai from Hawaii While examining Hawaiian specimens of Apterichtus in the collections of the Australian Museum, BPBM, CAS, and the USNM, we discovered 21 specimens of A. klazingai (Weber 1913) that had been collected in 20 m by the junior author along the Kona Coast of Hawaii. They differ from A. flavicaudus in vertebral counts and cephalic pores (Table 2), and in having numerous small brown spots along the posterodorsal surface of the head (Pl. 1c). They represent a new record for the Hawaiian Archipelago. Material examined of Hawaiian Apterichtus klazingai: BPBM 7906, 21(100-266), Waawaa Pt., Kona Coast, Hawaii.Published as part of John E.

Chlopsis
No full text<p>The most recent reviews of the genus Chlopsis were those of Lavenberg (1988) and Smith (1989).</p> <p>Lavenberg (1988) recognized four species from the eastern Pacific: C. apterus (Beebe and Tee Van, 1938), C. bicollaris (Myers and Wade, 1941), C. kazuko Lavenberg, 1988 and C. longidens (Garman, 1899). Although C. longidens is based on a leptocephalus and is probably the larva of one of the other species, Lavenberg (1988) did not conclusively identify this species with an adult. However, he did indicate that it was likely that it was the larva of C. bicollaris. Smith (1989) recognized six species: C. apterus, C. bicollaris and C. kazuko from the eastern tropical Pacific, C. olokun (Robins and Robins, 1966) from the eastern tropical Atlantic, C. bicolor Rafinesque, 1810 from the Mediterranean and Atlantic and C. dentatus (Seale, 1917) from the tropical western Atlantic, western Indian and western Pacific Oceans.</p> <p>Recent collecting in the Central Pacific by ORSTROM yielded three specimens of two undescribed species of this family. One additional specimen of one of these species from the Australian Museum had been previously misidentified as C. dentatus and was the basis for including the western Pacific Ocean in the distribution of that species by Smith (1989).</p>Published as part of <i>Kenneth A.

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
Ichthyapus acutirostris Brisout de Barneville
No full text[[Ichthyapus acutirostris Brisout de Barneville]] Comments on Easter Island and Hawaiian species of Ichthyapus In 1975 we (Randall and McCosker, 1975) provisionally identified Easter Island specimens of Ichthyapus as I. vulturis (Weber & de Beaufort 1916) and included Caecula (Sphagebranchus) platyrhyncha Gosline 1951 in its synonymy. We did so because they appeared to be identical in morphometry and intermediate in their vertebral and cephalic pore conditions. We surmised that the preopercular condition of four specimens from Hawaii and Kure (2 had 3 pores and 2 had 4 pores) was normal variation for that character. We were wrong. After examining additional specimens from Hawaii and elsewhere in the Pacific, we have determined that two species exist in the Hawaiian archipelago and that the Easter Island population is I. acutirostris Brisout de Barneville (1847) (illustrations of I. acutirostris appear in Blache & Bauchot 1972 and in Randall & McCosker 1975). We now recognize Hawaiian Ichthyapus to include I. vulturis (Fig. 3) (which have a comparatively larger eye, 124-134 total vertebrae, MVF=47.1-130.1, and 4 preopercular pores, n=20) and I. platyrhynchus (Figs. 3-4) (which have a smaller eye, 120-128 total vertebrae, MVF=48.6-124, and 3 preopercular pores, n=17). McCosker (2004: 171-173) recently proposed that Ichthyapus acutirostris, which had been described on the basis of two specimens (only one is extant) from "Haute-Mer, Océan équatorial," is the correct identity of specimens captured in Japan (Hatooka et al., 1995). He examined the extant syntype of I. acutirostris, compared the larger of Hatooka's 2 specimens to the Easter Island material, and found them all to be conspecific. In that the collector of the holotype of I. acutirostris (Monsieur Paul-Charles-Alexandre-Léonard Rang, 1793-1843, a French malacologist) never visited the South Pacific (few if any collections had been made at or near Easter Island before the 20th century) but had traveled to Japan (aboard the Levant after 1836), McCosker concluded that the remaining type specimen of I. acutirostris was probably collected from Japan. The collection of additional Easter Island specimens of Ichthyapus acutirostris as well as a specimen from Pitcairn Island (BPBM 11898, 427 mm) has allowed us to provide an expanded description of the morphometrics and vertebral counts of I. acutirostris (Table 3). All specimens have 3 preopercular pores, 5 temporal pores, and 5 lower jaw pores. Material examined of Ichthyapus acutirostris: MNHN 2119, 228 mm, locality unknown, the extant syntype.

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
