Asiopsectra luculenta Kovaleva & Kirejtshuk, 2016, sp. n.
No full textAsiopsectra luculenta sp. n. (Figs 1 –7, 16) Holotyp e, ♂ with labels “ IRAN, prov. Fars, Zagros, 5 km above Thangebolhayat (to Shiraz), 1750 m, 6–7.x. 2002, leg. P. Gyulai & A. Garai” (HNHM). The left mid leg of the holotype is lost. Diagnosis This new species differs from the second congener (below) in the smaller body size, the much larger eyes making the head wider than the anterior prothoracic foramen, the smaller mandibular sinuses, the less transverse pronotum with less projecting and rounded posterior angles, the shorter elytra with coarser sculpture and with the less raised longitudinal costae. The male genitalia of this new species (Fig. 16) are rather similar to those in another congener (Fig. 19) and differences in this organ between both species can be defined after a further study of additional material. Description Body length 5.30 mm, width 2.25 mm. Head and pronotum dull, elytra slightly shiny; body colouration brownish black, antennae dark brown; femora brown with lighter apices; tibiae, tarsi and mouthparts brownish yellow. Dorsum with subuniform short, semirecumbent, inconspicuous brownish hairs. Underside with fine recumbent brownish hairs. Head large, about 1.1 times as wide as distance between anterior angles of pronotum. Eyes very large, globular (Figs 3, 4). Supra-antennal carinae sharp, nearly contiguous from frontal view, slightly concave above antennal insertions from dorsal view. Mandibular sinuses moderately large. Pronotum transverse, about 1.65 times as wide as long along middle, trapezoidal, narrowing anteriorly, posterior angles rounded at apex, distance between them 1.8 times that between anterior angles; disc moderately convex and with pair of nearly indistinct paramedial impressions in anterior half and with scarcely conspicuous median impression. Elytra about 1.65 times as long as wide combined behind middle, and about 3.2 times as long as pronotum; humeri well expressed, sides behind them gently arcuate to apices; sutural edges slightly emarginate; disc subflattened, with irregular rows of “window” punctures of different size and two more or less expressed longitudinal costae on disc (?odd-numbered interstriae). Elytral integument very rough due to deep irregular and partly confluent depressions bearing oval “window” punctures in bottom of depressions, convex interspaces between punctures more or less obliterated and somewhat shiny. Abdomen convex; last abdominal ventrite with small, transverse patch of dense, dark excretory hairs in median part before broadly rounded apical edge (Fig. 7). Aedeagus as in Fig. 16. Etymology The epithet of the new species in Latin means “striking”, “distinguished”, “excellent”.Published as part of Alexey V. Kovaleva & Alexander G.

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

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
