Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Measurements (in mm) of Narsingiella clinotarsi sp.nov and N. narsingi Rao. (N = Total number of specimens; ABD= Anal Body Diameter, a = L/W; b=L/E; c = L/T; V= Vulva /L x 100) Parameters Narsingiella clinotarsi sp. nov. Narsingiella narsingi Rao Female: Gonad didelphic, amphidelphic. Vulva situated at midbody with indistinct vulval lips. Uterus filled with eggs in different developing stages. Tail, small, conical with pointed tip. Male: Prominent preanal sucker almost close to anus present. Caudal papillae 6: 1: 7 = 14 pairs, 3 pairs of preanal papillae are pedunculated and 3 pairs are sessile and grouped together. One pair of sessile adanal papillae present. Out of the 7 pairs of postanal papillae, 6 pairs are grouped together and pedunculated, whereas one pair is sessile and situated at a distance of 45 μm. Caudal alae indistinct. Spicules two and unequal, shaft of spicule trilobed. Gubernaculum small. Tail with a fine tip. Host: Bicoloured frog, Clinotarsus curtipes (Jerdon) -Deposited in Zoological Survey of India, Western Ghats Field Research Station, Calicut, Kerala, India, vide registration No. ZSI/ WGFRS /V/A- 677. Locality: Haligekerae, Muthodi Range, Bhadra Wildlife Sanctuary, Karnataka, India. Lat. 13 0 29 ’ – N; Long. 75 0 36 ’ – E. Altitude: 2900 ft. above MSL (approximately). Site of infection: Gut. Type material: Holotype male: ZSI/ NRS /IV/N/ 381, Paratype female: ZSI/ NRS /IV/N/ 382 (Zoological Survey of India, Northern Regional Station, Dehradun, India.). Diagnosis and relationships. Narsingiella clinotarsi sp. nov. is characterized by male having long esophagus, two unequal spicules with trilobed shaft, small gubernaculum and 14 pairs of caudal papillae in the pattern as 6: 1: 7 and female having long esophagus, short conical tail and vulva situated at midbody. Both the sexes with lips bearing digitiform projections. The new species differs from the only known species, N. narsingi Rao in several important characters. Esophagus in both sexes 1 / 3 rd of body in Narsingiella clinotarsi sp. nov. and 1 / 8 – 1 / 6 th in N.narsingi, lips of both sexes with digitiform projections in N. clinotarsi sp.nov., while lips of N.narsingi with three pairs of onchia. Tail of female N. clinotarsi sp.nov. is short and conical,while tail of N. narsingi female is long with tapering pointed end; Vulva situated at 50 % of body length in N. clinotarsi sp.nov as opposed to 35–42 % in N. narsingi Male of N. clinotarsi sp. nov. possess two unequal spicules with a trilobed spicule shaft (Figure 4 I), whereas, spicules of N. narsingi are equal and lack trilobed shaft. Gubernaculum is short in N. clinotarsi sp.nov (40 µm) and long in N. narsingi (50–80 µm). Number and pattern of caudal papillae in these two species also differs: 6: 1: 7 pairs in N. clinotarsi sp.nov and 6:0: 6 pairs in N. narsingi. All these characters differentiate the present specimens from the only known species of the genus N. narsingi and justifies its new species status. Bicoloured frog, Clinotarsus curtipes (Jerdon) is a new host record for the genus Narsingiella.Published as part of Rizvi, Anjum Nasreen, 2009, Two new species of amphibian nematodes from Bhadra Wildlife Sanctuary, Western Ghats, India., pp. 58-68 in Zootaxa 2013 on pages 64-67, DOI: 10.5281/zenodo.18586
Entedonomphale postmarginalis Shafee, Rizvi & Khan 1988, comb. n.
No full textEntedonomphale postmarginalis (Shafee, Rizvi & Khan, 1988), comb. n. (Figs 5, 6) Euderomphale postmarginalis Shafee, Rizvi & Khan 1988: 2 (description, key [as E. Postmarginalis]), 3 (illustrations, figs D and E [as E. Postmarginalis]). Type locality: Bullandshahr, Uttar Pradesh, India. Entedonastichus postmarginalis (Shafee, Rizvi & Khan): Hayat et al. 2005: 10 (type information). Type material examined. Holotype female [ZDAMU] dissected on two slides, as follows. Slide 1 (head, one antenna, mesosoma and most of metasoma, and legs (with some segments missing) [under two coverslips]), labeled: 1. “Ref. No. 723 sp. n.”, 2. “ HOLOTYPE Euderomphale postmarginalis Shafee, Rizvi & Khan det. M. Hayat, 2003 ”; Slide 2 (one antenna, one forewing, and the ovipositor [under the same coverslip]), labeled: 1. “ 723 [in pencil] Ref. No 723 sp. n.”, 2. “ HOLOTYPE parts Euderomphale postmarginalis Shafee, Rizvi & Khan det. M. Hayat, 2003 ”. Diagnosis. Body and appendages mostly dark brown. Toruli slightly below lover ocular line. Antenna (Fig. 5) with scape (not counting a small radicle) 4.1 x as long as wide, a little dilated basally and medially. Pedicel longer than funicle; F 1 a little smaller than F 2, 1.1-1.5 x as wide as long, apparently without longitudinal sensilla; F 2 1.6 x as wide as long, at least with 1 longitudinal sensillum; clava entire, 1.6-1.7 x as long as wide. Mesosoma shorter than metasoma. Midlobe of mesoscutum with 1 pair of setae; anterior margin of scutellum slightly angulate. Forewing (Fig. 6) about 3.1 x as long as wide, with disc almost hyaline (with a slight brownish tinge throughout, perhaps a little more pronounced behind marginal and stigmal veins) and setose behind marginal and stigmal veins and beyond venation (more sparsely so behind base of marginal vein, and bare posterior of cubital row of setae); stigmal vein about as long as postmarginal vein; the longest marginal seta about 1 / 2 of maximal forewing width. Petiole longer than wide. Entedonomphale postmarginalis is undoubtedly a good species. In Triapitsyn (2005), E. postmarginalis would key to the couplets together with the species that have a hyaline forewing (i.e., E. boccaccioi S. Triapitsyn from the USA, E. bicolorata (Ishii) from Japan, Germany, and Ukraine, and E. esenini S. Triapitsyn from Madagascar). Entedonomphale postmarginalis differs from all of them by the female antenna, both funicle segments of which are wider than long (Fig. 5). Comments. This species was described (and is still known) from a single female holotype “ex aleyrodid on Citrus sp.” (Shafee et al. 1988). The host record seems doubtful and thus needs verification.Published as part of Triapitsyn, Serguei V., Boyadzhiev, Peter S. & Antonov, Anton K., 2008, Taxonomic notes on Entedonomphale (Hymenoptera: Eulophidae), pp. 61-64 in Zootaxa 1816 on pages 62-63, DOI: 10.5281/zenodo.27436
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
