Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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

Pygidium: Transverse, fully margined, glabrous centrally, becoming more alutaceous towards edges; fine oviform punctures throughout. Legs: Protibia tridentate; spur curved gently apically; three longitudinal striae ventrally. Metatibial spur long, truncate apically. Aedeagus: Parameres almost as long as phallobase, laterally arcuate, with shallow concavity anteriorly (Fig. 8). Female paratype (Fig. 9). Head: Anterior clypeal edge evenly arcuate with continuous clypeal margin. Clypeal surface transversely rugose anteriorly, becoming more granulose posteriorly; genal edge rounded and acutely angled, surface with granules disappearing and becoming glabrous internally.

In smaller males the anterior declivity is completely granulose; the pronotal horns are reduced to tubercles and the cephalic horn is reduced to a broad equilateral triangle in frontal view. Derivatio nominis. This species is named after the coleopterist Edgar von Harold (1830–1886), who described Catharsius harpagus, the species with which subsequent authors have confused this new species. Diagnosis. This species, although very distinctive, might be confused with the smaller C. tricornutus (De Geer, 1778) with which it is found sympatrically. In the males of the latter, the more conical pronotal horns are longer, placed nearer the midline and diverge strongly. In the females, the clypeal carina of C. tricornutus is strongly bifurcate medially giving it a quadridentate appearance in frontal view, and the pronotal carina is straight, weakly produced and shorter than the clypeal carina.

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
Get PDFThis 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
Concavibalcis haterumaensis Takano & Tsuzuki & Kano 2022, n. sp.
No full textConcavibalcis haterumaensis n. sp. (Fig. 1) Type locality. Nishi-hama, Hateruma Island, Taketomi, Okinawa, Japan (24°04'06"N, 123°45'46"E), sandy bottom at a depth of 4 m. Type material. Holotype NSMT-Mo 79320; 8 paratypes NSMT-Mo 79321; 3 paratypes MPM Coll. No. 21794a–c, all collected from the type locality on May 30, 2019. 2 paratypes (MPM Coll. No. 21794a, b) coated with platinum for SEM observation. Other material examined. 12 specimens MPM Coll. No. 21795, collected together with the type specimens. Etymology. The name refers to the type locality, Hateruma Island. Distribution. Known only from the type locality. Diagnosis. Species of Concavibalcis with a small, thick, white translucent shell, lacking chalky appearance. Teleoconch surface decorated with very fine spiral ridges. Aperture ovate, callused; outer lip simple, curved, constricted below suture, with most protruding part at half of aperture height in lateral view. Description. Shell conical with blunt apex, up to 3.1 mm high, thick, solid, white translucent (Fig. 1A, B). Protoconch dome-shaped, smooth, glassy translucent white, with 1.3 whorls; demarcation line with teleoconch faint, straight, opisthocline; exposed part 220 μm wide and 250 μm high (Fig. 1C). Up to 6.4 teleconch whorls, concave near shoulder and convex below; suture well defined and encircled by a rounded keel (Fig. 1B); incremental scars distinct (Fig. 1D), situated at 0.7, 1.6, 2.0, 2.7, 3.4, 4.1, 4.5, 5.0 and 5.5 whorls from aperture in holotype. First two to three teleoconch whorls bear short, oblique, slightly curved ridges on upper two-thirds and continuous spiral ridges on lower one-third of each whorl (Fig. 1E). Later whorls bear spirals only, which are stronger and more widely spaced towards suture of next whorl (Fig. 1D). Last adult whorl occupies 55% of total shell height. Aperture ovate; outer lip simple, curved, retracted near suture, sigmoid with most protruding part at half of aperture height in lateral view; parietal wall and columellar lip joining in a slight arc; columellar and parietal callus well developed; basal lip rounded. Dimensions. Holotype: 3.0 mm in SH and 1.2 mm in SD; 11 paratypes: 2.0– 3.1 mm in SH and 0.8–1.2 mm in SD. Remarks. The assignment of the present new species to Concavibalcis is supported by its shouldered, concave teleoconch whorls, and its blunt apex with a dome-shaped paucispiral protoconch (Fig. 1; Warén 1980b). The former condition is rare among the Eulimidae and found in only a few other genera, including Oceanida de Folin, 1870 and Scalaribalcis Warén, 1980. However, Oceanida differs in having a taller, pupiform protoconch, and Scalaribalcis in having an ovate outline of the teleoconch with a much broader aperture (Warén 1983a). The shell apex is blunt in such genera as Fusceulima Laseron, 1955, Halielloides Bouchet & Warén, 1986 and Teretianax Iredale, 1918, but their teleoconch features differ greatly from those of the present species and of C. scalaris, the type and only known species of Concavibalcis (Warén 1983b; Souza & Pimenta 2014; Hori & Matsuda 2017). Concavibalcis haterumaensis n. sp. is distinguished from C. scalaris in having (1) a smaller, thicker shell and (2) fine spiral ridges on teleoconch whorls. The two species have nearly the same number of teleoconch whorls (up to 6.4 and 6.5, respectively), meaning that C. haterumaensis n. sp. (3.1 mm high) is more tightly coiled with a lower expansion rate of the aperture than C. scalaris (5.1 mm high). The presence or absence of fine spirals is a species-specific character also in other eulimid genera (e.g. Annulobalcis Habe, 1965, Melanella Bowdich, 1822 and Trochostilifer Warén, 1980; Warén 1980b; Gofas et al. 2011; Dgebuadze et al. 2012). Furthermore, (3) the polished translucent shell of the new species differs from the chalky shell of the type species, although the latter chalky appearance may be attributable to corrosion in the specimens examined (see Warén 1980b). Their habitats also differ from each other: (4) C. haterumaensis n. sp. was collected from a shallow subtidal site, whereas C. scalaris lives in deeper, bathyal waters (365–400 m; Warén 1980b). Several eulimid genera exhibit a similar broad bathymetric range (e.g. Melanella, Pelseneeria Koehler & Vaney, 1908, Stilapex Iredale, 1925 and Thyca H. Adams & A. Adams, 1854; Warén 1980 a, 1981, 1983a; Hori & Matsuda 2017; T. Takano personal observation). The genus Concavibalcis remains to be the least studied among the Eulimidae from phylogenetic and ecological perspectives. Eulimid species in closely related genera exploit hosts of the same echinoderm class (Warén 1983a; Takano & Goto 2021). Future phylogenetic reconstruction for Concavibalcis based on live-taken specimens may lead to a better understanding of its parasitic ecology and vice versa.Published as part of Takano, Tsuyoshi, Tsuzuki, Shouji & Kano, Yasunori, 2022, Description of a second species of the eulimid genus Concavibalcis (Gastropoda: Vanikoroidea), pp. 397-400 in Zootaxa 5093 (3) on page 398, DOI: 10.11646/zootaxa.5093.3.8, http://zenodo.org/record/591002
