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

Type locality. Abercorn, Zambia. Diagnosis. Pronotum red with purple luster; femora with apical half black, tibiae black; tarsal claw pectinations extremely short, the longest pectination shorter than one-fifth width of claw base (Fig. 70). Description. Length: 9.8–10.9 mm, width: 2.9–3.4 mm. Head and abdominal sterna with blue luster; neck, pronotum, scutellum, thoracic sterna, episterna, and epimera, Ant 4–11, and basal half of femora red or brown; pronotum with purple luster; elytra with green luster; apical one-third or apical half of hind femora, tibiae, and apical half of Ant 1 black; tarsomeres, Ant 2, Ant 3, and basal half of Ant 1 dark brown. Head densely punctate on vertex; labrum with medial lobe slightly protruded anteriorly; Ant 1/Ant 3 5 3.02 (2.88–3.14); genae oblique, hardly tumid; eyes large, convex, 2.5 times as long as genae. Pronotum short, cylindrical, widest at apical third, PL/PW 5 1.38 (1.34–1.43), HW/PW 5 1.19 (1.11–1.26); slightly widened from apical angles to anterior one-third, then narrowed posteriad, slightly sinuate before basal angles; basal angles obtuse, weakly protruded laterally. Elytra nearly parallel in basal half, slightly widened posteriad to apical fourth, then narrowed to apex; EL/EW 5 1.85 (1.79–1.99), EW/PW 5 2.16 (1.95–2.26); striae shallow, punctate; intervals flat, densely punctate; outer apical angles nearly rectangular, not pointed (Fig. 38). Protarsomere 3 strongly asymmetrical in male; tarsal claws with 3–5 min pectinations, length of the longest pectination less than one-fifth width of claw base (Fig. 70). Aedeagus stout, with apical lamella moderately long, thin, rounded at apex (Figs. 105–106). Distribution. Congo, Zambia. Etymology. This species is named for the very short pectinations on its tarsal claws. Remarks. Members of this new species are similar to those of another African Dendrocellus species, D. bicoloripennis n. sp., but differ from them in having unicolorous green elytra with distinct humeri and nearly parallel lateral margins. In D. bicoloripennis adults, the elytra are bicolored bluish green and dark purple or black with indistinct humeri and lateral margins distinctly widened posteriorly.Published as part of Liang, Hongbin & Kavanaugh, David H., 2007, Review of the Genus Dendrocellus Schmidt-Göbel (Coleoptera: Carabidae: Dryptini), with Descriptions of Seven New Species, pp. 1-39 in The Coleopterists Bulletin (Oxford, England) (Oxford, England) 61 (1) on pages 1-39, DOI: 10.1649/934.1, http://zenodo.org/record/546166
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

Elytra with sharp outer angles (Fig. 41), intervals densely punctate; femora with apical third black, basal-two thirds brown; tibiae and tarsi yellow, protarsomere 3 asymmetrical in male; tarsal claws with 5–6 long pectinations, length of the longest pectination equal to width of claw base (Fig. 60). Description. Length 10.6–11.0 mm, width 3.1–3.4 mm. Black, head and pronotum with blue luster mixed with slight green luster; elytra with green luster mixed with slight coppery luster; apical third of Ant 1 dark brown, basal twothirds brown, Ant 2 and Ant 3 brown, Ant 4–11 yellow; apical third of femora black, basal two thirds brown; tibiae and tarsi yellow. Head wider than pronotum, HW/PW 5 1.22 (1.18–1.27); vertex convex; Ant 1/Ant 3 5 3.53 (3.47– 3.64); labrum (Fig. 27) coarsely punctate, with medial lobe slightly protruded anteriorly; genae long, moderately tumid; eyes large, 2.5 times as long as genae. Pronotum densely punctate, narrow, PL/PW 5 1.53 (1.47–1.60); lateral margins gradually widened from apical angles to middle, sinuate before basal angles; basal angles protruded laterally, nearly rectangular; basal foveae very deep; middle line shallow. Elytra short, EL/EW 5 1.75 (1.69–1.79), EW/PW 5 2.19 (2.11–2.33); lateral margins widened posteriad to apical third, then narrowed to apex; outer angles strongly dentate, pointed (Fig. 41); intervals convex, densely punctate, interspace between two adjacent punctures narrower than diameter of punctures.

Aedeagus with apical lamella short, round at apex (Figs. 101–102). Variation. The pronotum in the holotype is shorter (PL / PW 5 1.47), and lateral margins are more rounded than in the paratypes (PL / PW 5 1.52–1.60). Distribution. Presently known from three provinces of China: Jiangxi, Fujian, and Guangdong. Etymology. This new species is named for China, the country of its type locality. Remarks. Members of this new species are similar to those of D. unidentatus (Macleay). However, the lateral margins of the pronota are more rounded before the middle (Fig. 20), the femora have a longer black portion, the tibiae are yellow, and the genae are more rounded than in D. unidentatus members. They are similar also to D. schultzei (Heller) members in shape of the pronotum and elytral outer angles, but differ from the latter in having green and coppery elytra and their tibiae and bases of femora all pale yellow (all black in D. schultzei).Published as part of Liang, Hongbin & Kavanaugh, David H., 2007, Review of the Genus Dendrocellus Schmidt-Göbel (Coleoptera: Carabidae: Dryptini), with Descriptions of Seven New Species, pp. 1-39 in The Coleopterists Bulletin (Oxford, England) (Oxford, England) 61 (1) on pages 1-39, DOI: 10.1649/934.1, http://zenodo.org/record/546166
