Glenea changchini Lin & Lin, 2011, sp. nov.
No full textGlenea changchini sp. nov. (Figs 1–8) Description (based on three males): Male: length: 21.8 –24.0 mm, humeral width: 6.2–6.7 mm. Body dark violet. Head violet-black, with two light blue pubescent stripes on occiput, which extend around superior eye lobes and antennal tubercles. Frons with inferior eye lobes surrounded with light blue pubescent stripes which cross genae and reaching clypeus; tempora covered with light blue pubescence. Antenna red brown, basal three antennomeres darker and with light blue pubescence on ventral and inner sides, others with a faint grayish pubescence. Prothorax dark violet, pronotum with three light blue pubescent stripes (one median and one on each lateral margin) and each side with a large white patch around coxa (propleura pubescent). Scutellum with white or light blue pubescence. Elytron dark violet, with 9–11 snow-white or light blue markings (named in Fig. 3); A, B at basal fourth and C at apical fourth are more stable than others in both position and shape; D and d are smaller and sometimes absent; E-e, F-f and G-g forming oblique lines and sometimes confluent; e, f and g are quite variable in shape. Ventral surface reddishviolet; with several whitish maculae: mesepisternum, mesepimeron and most of metepisternum whitish pubescent; two patches on each side of apical abdominal segments 1–4; other parts with fulvous brown pubescence. Femora reddish-brown and glossy; tibiae and tarsi reddish-brown and with hair and pubescence, especially apical part of hind tibiae and tarsi densely covered with fulvousbrown hair and pubescence. Head slightly narrower than prothorax. Eyes medially emarginate, inferior eyelobes two times as high as genae below. Antennae relative slender, longer than body (9 th antennomere reaching elytral apex); antennomere ratio: male: 25: 5: 40: 30: 30: 27: 27: 23: 23: 22: 30. Last antennomere (Fig. 4) subdivided at apical third. Prothorax densely punctured, slightly narrower from base to apex. Elytron densely and coarsely punctured, gradually narrower apically, with 2 lateral carinae, neither from base nor reaching apex; apex transversely truncated, rounded at inner angle and with a very minute and scarcely perceptible tooth at outer angle. Legs slender, middle tibiae hardly grooved, hind femur reaching fourth abdominal segment, first hind tarsal segment subequal to following two segments combined. Tarsal claws simple. Male genitalia (Figs 5–7): Tegmen length about 3.4 mm; lateral lobes stout, each about 0.7 mm long and 0.3 mm wide, with a curved ridge at base; apex with fine setae shorter than half of lateral lobes; basal piece well-developed and not bifurcated; median lobe plus median struts slightly curved (Fig. 5 b), obviously longer than tegmen (22: 17); median struts more than half of whole median lobe in length; dorsal plate shorter than ventral plate; apex of ventral plate (Fig. 6) rounded; median foramen elongated, pointed at apex (angle about 30 degree); internal sac more than twice as long as median lobe plus median struts, with four pieces of basal armature (located at middle of median struts), two bands of supporting armature (very weak), and three rods of endophallus, rods subequal, each about 3.8 mm, longer than tegmen. Tergite VIII (Figs 8 a, 8 c) much broader than long, apex truncated to slightly emarginated, with moderate long setae at sides, setae in the middle shorter and sparser. Sternite IX subequal to ringed part of tegmen in length. Female unknown. Diagnosis. Though the external appearance is similar to G. diana, G. paradiana and G. subsimilis, this species differs not only by the pubescent markings, but also in the following characters: elytral apex rounded at the inner angle (usually bidentate in Glenea), claws simeple, and basal armature located at middle of median struts (usually located out of median lobe in other Glenea spp.). Etymology. The species is named after Mr. Changchin Chen (Tianjin, China), who offered the authors lots of material, support and kind help in various ways. Remarks. The species is similar to subgenera Rubroglenea (pronotal puncturation and elytral apex different) and Macroglenea (male claw, genitalia and elytral apex different). The genus Glenea, as considered here, includes a diverse, and probably multi-generic assemblage of species. For example, some Heteroglenea species were previously placed in Glenea (Lin et. al, 2009). To clarify the subgeneric and generic relationships, a world-wide study of Glenea is required. Distribution. China: Yunnan. Material examined. Holotype (23.0 mm long), male, China, Yunnan prov., Jinping county, Ma’andi, Biaoshuiyan (22 ° 44 'N 103 ° 29 'E), alt. 1350 m, 2010. V. 13, leg. Xiaodong Yang (IZAS, IOZ (E) 1859451). Paratypes: 1 male, Yunnan prov., Jinping county, Ma’andi, Biaoshuiyan (22 ° 44 'N 103 ° 29 'E), alt. 1350 m, 2010. V. 15, leg. Wenhsin Lin (CCCC); 1 male (21.8 mm long), same data (IZAS, IOZ (E) 1859452). Correction. In the paper “Eight species of the genus Glenea Newman, 1842 from the Oriental Region, with description of three new species (Coleoptera: Cerambycidae: Lamiinae: Saperdini). Zootaxa, 2155: 1–22 ”, there is an error which needs correction. In Figures 25–26 on page 12, ‘ subrubricollis ’ in 25 L and 26 L should read ‘ nigrorubricollis ’. We thank Dr. Carolus Holzschuh (Villach, Austria) for bringing this to our attention.Published as part of Lin, Meiying & Lin, Wenhsin, 2011, Glenea changchini sp. nov. from Yunnan of China (Coleoptera: Cerambycidae: Lamiinae: Saperdini), pp. 13-17 in Zootaxa 2987 on pages 13-14, DOI: 10.5281/zenodo.20811
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
