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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
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

The new species is here compared with congeners based on non-overlapping and differing characters: vertebral scales enlarged (vs not enlarged in P. chinensis (Barbour, 1912), P. macularius Theobald, 1868, P. margaritophorus (Jan 1866), P. vindumi Vogel, 2015); loreal not in contact with orbit (vs in contact in P. boulengeri (Angel, 1920), P. monticola (Cantor, 1839), P. stanleyi (Boulenger, 1914), P. vindumi) and Amblycephalus yunnanensis Vogt, 1922; eight mid-dorsal vertebral scales keeled (all scales smooth in P. boulengeri and Amblycephalus kuangtungensis Vogt, 1922, 9–13 keeled dorsal scales in P. komaii (Maki, 1931), 3–5 in P. modestus); two anterior temporals (vs one in P. nigriceps Guo & Deng, 2009); ventrals 160–183 (vs 195–213 in P. nuchalis (Boulenger, 1900), 189–194 in P. iwasakii (Maki, 1937), 151–160 in P. stanleyi, 190–196 in P. monticola, 130–160 in P. margaritophorus), 6–7 maxillary teeth (vs 4–5 in P. chinensis (Barbour, 1912) and P. boulengeri, 3–5 in P. menglaensis Wang, Che, Liu, Li, Jin, Jiang, Shi & Guo, 2020); prefrontals in contact with orbit (vs not in contact in P. carinatus (Boie, 1828)); subcaudals 65–70 in males, 52 in female (vs 71–79 in P. atayal You, Poyarkov & Lin, 2015, 37– 45 in P. andersonii); single nasal (vs two in P. nuchalis and P. stanleyi); dentition asymmetry index 4.55 in males (13.51 in P. komaii, 29.03 in P. atayal). The new species shares several characters with members of its clade and is here compared to each species in greater detail based on differing and non-overlapping characters. The new species differs from P. formosensis in bearing keeled dorsal scales (vs smooth in P. formosensis), dentition asymmetry index 4.55 in males (vs 16.13 in P. formosensis). The new species differs from P. mengziensis Wang, Che, Liu, Li, Jin, Jiang, Shi & Guo, 2020 in bearing 6–7 maxillary teeth (vs 3–5 in P. mengziensis) and in having the dorsum with thin black bands (vs connected black reticulations throughout the body in P. mengziensis). The new species is most similar to P. hamptoni in sharing the plesiomorphic state, where the loreal shield does not touch the orbit and is separated by the preocular. However, the new species differs from the species as follows: ventrals 160–183 (vs 197–202); two anterior temporals (vs a single temporal scale in P. hamptoni); subcaudals 65–70 in males, 52 in female (vs 96 in P. hamptoni); bearing 8 keeled dorsal scales (vs only a single row keeled in P. hamptoni); hemipenis unilobed and not forked (vs deeply forked in P. hamptoni). Etymology The specific epithet is a patronym honoring wildlife photographer Sandesh Kadur for his contribution to biodiversity documentation in the Himalayas, in particular Arunachal Pradesh, as well as for his constant support to the authors during the expedition.

Seven supralabials, seventh longest. First to third supralabials smallest, first supralabial only contacts second supralabial, rostral and nasal. Second supralabial in contact with nasal, preocular, loreal and first and third supralabials. Third supralabial in contact with preocular, second and forth supralabials and making contact remotely with loreal. Supralabials separated from the orbit by a crescent-shaped subocular. Mental short, broad, triangular. Infralabials 7, anterior five infralabials short and narrow, fifth onwards larger. First infralabials of both sides in broad contact, separate the mental from the genials. Sixth infralabial broadest. First six infralabials in contact with the genials. Anterior genials almost twice as long as wide; anterior genials in broad contact, posterior genials only in remote contact. Body laterally compressed, ventral surface a little flattened. Dorsal scales in 15:15:15 rows. Dorsal scales imbricate, regularly arranged, vertebral and adjoined scale rows enlarged and larger than the outermost dorsal scales. Eight scale rows on the mid-dorsum (including vertebral rows) keeled; other dorsal scale rows scales smooth and glossy, lacking apical pits. Ventral scales 160 in number + 2 preventrals.Anal shield undivided, slightly larger than last ventral scale, its posterior margin overlaps nine small, irregular scales on each side, in addition to pair of larger subcaudals medially. Subcaudals paired, 70 in number. Tail terminates in a sharp tapering apical spine. Total length 694 mm, tail length 144 mm, tail/total length ratio 0.207. Hemipenial morphology (paratype NCBS BH655) The organ is fully everted and expanded (Fig. 4). Hemipenis short, unilobed, stout and unicaliculate; lobe extends for about 60% of the hemipenis; capitulum restricted to sulcate and dorsal surfaces of the organ, covering nearly half of the lobe’s length at the level of the sulcus spermaticus; capitulum smooth, except for two rows of calyces spanning almost the entire width of the organ; on asulcate surface, lobes ornamented with three to four parallel broken rows of mediolaterally enlarged and papillate body calyces; sulcus spermaticus simple; the sides of the sulcus spermaticus are smooth; truncus and hemipenial base is wrinkled and completely nude. Colouration in preservative (Fig. 2) Overall, in a shade of brown with 28 paired black transverse bands from nape to the vent. Some of these bands are distinct, whereas some are merely black spots that connect rudimentarily to form bands. The head bears a large black blotch from which two black longitudinal stripes (3–4 scales wide) run on each side of the neck leaving a pale central portion. The ventral scales are white or cream colored with sparse black mottling. Dentition (paratype, ♂ NCBS BH655) (Fig. 5) Maxilla with six functional (12 total) on right and seven (14 total) on left teeth. All the teeth subequal, lacking a distinct diastema. Pterygoid with total of 6–7 teeth. Palatine with 13–14 functional (24–25 total) teeth that gradually decrease in size posteriorly. Mandibles with 21 and 23 (more than 50 total) functional dentary teeth of left and right, respectively. Variation shown by paratypes and referred specimens The paratypes match the holotype in all respect except for the details noted herein: dorsal scales of female paratype BNHS 3575 are smooth, lacking keels, likely a character that is sexually dimorphic, in addition to fewer subcaudal scales. The color of individuals varies greatly in being light brown to dark blackish brown to reddish orange. Other differing characters are listed in Table 1. Genetic divergence Interspecific divergence observed is 12–24% for cyt b and intraspecific genetic divergence is 1%. (Appendix 2). Natural history The type specimens were captured on low bushes along roads on the outskirts of Kamlang Wildlife Sanctuary at night. All the specimens were observed actively foraging after dusk. The habitat at the type locality is contiguous with the adjoining Namdapha Tiger Reserve and Mehao Wildlife Sanctuary, which lie in the Mishmi Hill range. Mishmi Hills lie between the Himalayas and the Indo-Burma biodiversity hotspot. The adjoining areas of Myanmar also share similar biotope and it is likely that the new species will be distributed in Myanmar in addition to India. The species was found in sympatry with Pareas monticola, Boiga siamensis Nutaphand, 1971, Bungarus niger Wall, 1908, Ahetulla sp. and Trimeresurus popeiorum Smith, 1937. The new species is common throughout the sampled area ranging from an elevation of 300 m to 1200 m, whereas P. monticola appears to be rare and only a single specimen was found at lower elevation (<300 m). Distribution Currently, the new species is known only form the type locality, a tropical wet evergreen forest.Published as part of Bhosale, Harshal, Phansalkar, Pushkar, Sawant, Mandar, Gowande, Gaurang, Patel, Harshil & Mirza, Zeeshan A., 2020, A new species of snail-eating snakes of the genus Pareas Wagler, 1830 (Reptilia: Serpentes) from eastern Himalayas, India, pp. 54-73 in European Journal of Taxonomy 729 (729) on pages 57-63, DOI: 10.5852/ejt.2020.729.1191, http://zenodo.org/record/566218

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
