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
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
Chlopsis bidentatus Tighe & McCosker, 2003, sp. nov.
No full textChlopsis bidentatus sp. nov. (Figs. 1, 2, 3B) Holotype: MNHN 2001-1080, 167 mm total length, New Caledonia, 23º 48' S, 168º 17' E, depth 444-503 m, captured with beam trawl, Campagne Bathus 3, Station CP 814, 28 November 1993. Paratype: MNHN 2001-1078, 132 mm TL, Fiji, Somo-Somo Strait, 16E 27 í S, 179E 34.8' W, depth 300-370 m, captured with Waren dredge, Campagne Bordau 1, Station DW 1454, 04 March 1999. Diagnosis. Distinguished from all other members of the genus Chlopsis by the combination of the following characters: pigmentation bicolored, dorsal origin approximately one eye-diameter behind gill opening, and vomerine dentition in two biserial rows anteriorly. Description. Total vertebrae 125 (128), predorsal vertebrae 11 (11), preanal vertebrae 31 (32), precaudal vertebrae 42 (41). Proportions as percent of TL: predorsal length 13.2 (13.8), preanal length 33.5 (34.2), head length 11.1 (10.3), depth at anus 2.9 (2.6). Proportions as percent of head length: eye diameter 13.4 (13.5), interorbital width 12.1 (10.6), snout length 22.9 (22.1), tip of snout to rictus of jaw 35.0 (33.6). Body moderately elongate, slightly compressed. Dorsal fin begins slightly more than one eye diameter posterior to gill opening (Fig. 6). Head moderate in length, relatively deep. Snout relatively broad. Gape short, rictus at posterior margin of eye. Anterior nostril tubular, slightly behind tip of snout, directed anterolaterally. Posterior nostril a posteroventrally directed low tubular opening (covered by a flap) on lip in front of vertical from middle of eye. Lateral line on body absent except for one pore in branchial region, anterior to the gill opening (Fig. 6). Supraorbital pores three: first (ethmoidal) at anteroventral tip of snout, second anteromedial to base of anterior nostril, and last above and behind anterior nostril. Infraorbital pores four: first just behind anterior nostril, second midway between anterior and posterior nostrils, third below posterior nostril, and last below middle of eye. Preoperculomandibular pores five; first near tip of lower jaw, second below interspace between anterior nostril and infraorbital pore 1, third below interspace between infraorbital pores 1 and 2, forth below posterior nostril, and last below and slightly posterior to infraorbital pore 4. Maxillary teeth (Fig. 3B) conical, slightly recurved, in 2-3 irregular rows, increasing in size from outer to inner, a total of 18-20 teeth in the inner row. Intermaxillary teeth conical, slightly recurved, with approximately 20 teeth in a round patch (more teeth can be seen on a radiograph of the holotype, but only about 20 penetrate through the tissue in the mouth). Mandibular teeth like those of the maxilla, except in 4-5 irregular rows anteriorly, reducing to 2-3 posteriorly, with 16-20 teeth in the inner row. Vomerine dentition shorter and stouter, slightly compressed, in two longitudinal series, weakly biserial anteriorly and uniserial posteriorly, 15-16 slightly larger teeth in the longer inner row, and 7-8 smaller teeth in the outer biserial row. Dentition of paratype very similar in both counts and arrangement to those of the holotype. Color of body light brown above and distinctly white ventrally; ventral light area strongly demarcated from the darker dorsum of the snout, starting on unpigmented anterior nostril, continuing back above posterior nostril to ventral margin of eye; tip of lower jaw also pigmented (Fig. 6); posterior to eye, dorsal edge of ventral light area becomes more irregular, but extends dorsally to the gill opening; ventral light area then tapers to base of anal fin slightly behind anus, but continues along base of anal fin for approximately 2/3 of body length; anal fin remains unpigmented to near tip of tail; ventral base of caudal fin and posterior portion of anal fin base much darker than rest of body. Etymology. The name bidentatus is from the Latin bi (two) and dentatus (toothed) in reference to the distinctive vomerine dentition. Remarks. Chlopsis bidentatus is similar in overall appearance to several other members of the genus Chlopsis. Chlopsis apterus, C. bicollaris and C. kazuko, all from the eastern Pacific Ocean, are all also bicolored. The posterior origin of the dorsal fin (at least one eye diameter behind the gill opening) separates C. bidentatus from C. bicollaris and C. kazuko. Chlopsis apterus, which also has the dorsal origin behind the gill opening, has a higher vertebral number (125-128 in C. bidentatus versus 134-140 in C. apterus). Chlopsis bicolor, from the Atlantic Ocean, is very similar in both meristics and morphometrics, as well as in its coloration. Several aspects of the dentition of C. bidentatus, especially the anterior biserial vomerine dentition, clearly separate C. bidentatus from C. bicolor. All other species in the genus Chlopsis can be distinguished from C. bidentatus by coloration. Chlopsis olokun, from the eastern Atlantic, is a fairly uniform tan or gray color, while C. dentatus (from the Atlantic and Indian Oceans) and C. slusserorum (described herein from the Pacific) have banded, blotched or mottled coloration. In the past, differences in vomerine dentition like that described for C. bidentatus would result in the description of a new genus; for example, Robinsia in Böhlke and Smith (1967), and Boehlkenchelys in Tighe (1992). However, due to the overall morphological similarity of this species to that of others in the genus, and the lack of any hypothesis of relationships within the family, we have taken the conservative approach of describing it within the genus Chlopsis. Relationships within the family are being studied by the senior author, and may later determine whether or not this is the correct decision.Published as part of Kenneth A. Tighe & John E.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
