Echiodon
No full text[[Genus Echiodon]] The genus Echiodon Thompson, 1837, comprises a group of 12 known species of pearlfishes found in a depth range of 18-2000m (Markle and Olney 1990; Williams and Machida 1992; Markle 1999). Echiodon species are mainly deep-pelagic forms, although Markle (1999) suggested at least some may be facultative commensals (in benthic invertebrates like some other pearlfishes). Six of the 12 species of Echiodon are found in temperate waters of the Southern Ocean. During cruise ICEFISH-04 (May to July 2004) across the South Atlantic on RVIB NATHANIEL B. PALMER, a specimen of Echiodon was captured at the Tristan da Cunha Group. Originally thought by me to represent the circumglobal, austral E. cryomargarites Markle, Williams and Olney, 1983, it possesses several characters in combination that reveal it is unnamed.Published as part of M.

Pachycara Zugmayer
No full text[[Pachycara Zugmayer]] Fishes of the eelpout genus Pachycara inhabit the upper slopes and abyssal plains of most regions, but are notably absent in the western Pacific, Mediterranean Sea and Arctic Ocean (Anderson 1989). Seven species have been described since the senior author’s 1989 paper (Møller 2003; Anderson and Fedorov, 2004; Biscoito and Almeida, 2004). Less than half (38%) of the species occur in the bathyal zone; the rest are abyssal.Published as part of M.

Microbrotula
No full text<p>[[Genus Microbrotula]]</p> <p>Gosline (1953) established the genus Microbrotula for two species of livebearing brotulas from coral reef and rubble areas in Hawaii, with M. rubra the type species. The second species, M. nigra, was transferred to Oligopus Risso where it was a homonym and renamed O. waikiki, now Grammonus waikiki (Cohen, 1964; Nielsen and Cohen, 1999). Within their redefined subfamily Bythitinae, family Bythitidae, Cohen and Nielsen (1978) suggested Microbrotula might be a shallow-water derivative of the bathyal genus Cataetyx. Machida (2000) considered his new genus Acarobythites close to Microbrotula which it resembles in many characters, but differs from it in its lack of scales, 11-12 caudal-fin rays, morphology of the anteriormost neural spines, vomerine teeth arranged in a single row, indistinct lateral line and short pectoral and pelvic fins.</p> <p>Cohen and Wourms (1976) described Microbrotula randalli from five specimens taken on reefs at Efate Island, Vanuatu, and American Samoa. Additional material I have examined is listed below. Cohen and Nielsen (1978) alluded to Microbrotula specimens from the Red Sea, and Nielsen and Cohen (1999) stated that several undescribed species occur in the Indo-Pacific region. The first southwestern Indian Ocean record of Microbrotula was brought to my attention from scuba collections made by Mr. Andy Bentley at Aliwal Shoal, South Africa, in the summer of 2002. The purpose of this paper is to describe this material and re-diagnose Microbrotula Gosline.</p>Published as part of <i>M.

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

USNM 356656 (1 specimen; 114 mm SL), Scotia Sea, W. of South Orkney Islands, 60°45.5'S, 48°13.5'W, 2511-2542 m, ISLAS ORCADAS coll. UMO 116, 10 ft beam trawl, 18 Feb. 1976, H. H. DeWitt.</p> <p>Diagnosis. Oidiphorus mcallisteri is distinguished from its only congener, O. brevis, by the following combination of characters: pelvic fins present; preoperculomandibular pores 7; suborbital pores 5; pectoral fin rays 14-17; precaudal vertebrae 18; dorsal fin origin associated with vertebrae 3-4.</p> <p>Description. Vertebrae 18 + 51 = 69; D 64; A 52; P 16; C 7; pelvics 2; branchiostegal rays 6; gill rakers 1 + 7; vomerine teeth 11; palatine teeth 9/9; pseudobranch and pyloric caeca absent; preoperculomandibular pores 7; suborbital pores 5 + 0; postorbital pores 2; supraorbital (nasal) pores 2; occipital and interorbital pores absent. Following proportions as percent SL: head length 20.8; head width 12.5; head depth 11.5; predorsal length 21.1; preanal length 41.2; pectoral base depth 6.8; pectoral-fin length 12.5; body depth 9.3; gill slit length 9.2.

Pectoral base/length ratio: 53.9%.</p> <p>Dorsal edge of gill cover forming horn-like projection when pulled forward owing to subopercular ramus projecting well above opercle, characteristic of Oidiphorus. Single, low pyramidal papilla between each mandibular and suborbital pore, none on cheeks or top of head. First gill arch with single, miniscule raker on upper limb, unlike types. Lateral line mediolateral, difficult to trace in this faded specimen (Anderson, 1988, mistakenly stated lateral line to be absent).</p> <p>Remarks. This is the third known specimen of O. mcallisteri and is slightly larger than the two types (Anderson, 1988), but agrees well with them in all respects. It is a ripe female and had 33 ova 1.5-2.2 mm in diameter, 23 of them 2.0 mm or larger.</p>Published as part of <i>M. Eric Anderson, 2006, Studies on the Zoarcidae of the southern hemisphere. X.
