    13. Dasyproctus tsunekii Binoy, Girish Kumar & Santhosh, sp. nov. (Figs 111–120) urn:lsid:zoobank.org:act: 840505BD-857F-4F0F-AD8E-5EB8D22C30E3 Diagnosis. The new species can be identified by the following combination of characters: distinct furrow beyond IOC on frons, almost reaching anterior ocellus; scape yellow with baso-ventral brown patch; mesosoma black with pronotal lobe and pair of oblong antero-submedial maculae on pronotal collar, pale yellow; metasoma black with faint yellow patch on Gt 5. It resembles D. attenboroughi sp. nov. in having: clypeus antero-medially narrower than antennal torulus; prepectus black; hind femur completely brown; Gt 3 immaculate. It differs from D. attenboroughi sp. nov., however, in having the area beyond IOC declivous, distinct furrow beyond IOC onto frons, almost reaching anterior ocellus (in D. attenboroughi sp. nov., no declivity or furrow present beyond IOC); Gt 2, Gt 4 and Gt 6 immaculate (in D. attenboroughi sp. nov., Gt 2, Gt 4 and Gt 5 maculate); supra orbital fovea well defined, longer than broad (in D. attenboroughi sp. nov., supra orbital fovea indistinct); Gt 5 with an indistinct yellow spot laterally (in D. attenboroughi sp. nov., Gt 5 with a pair of non- continuous yellow streak medially). Description: Holotype ♂ (Figs 111–120). Body length 4.86 mm; fore wing length 2.93 mm. Colour. Body matt black with following parts variously coloured: scape pale yellow with dorso-basal brown patch; pedicel and fu 1 brown with apical edge pale, remaining antennomeres brown; mandible reddish brown with base and apex black, pronotal collar black with a pair of oblong pale yellow anteriorly; pronotal lobe pale yellow; all coxae and trochanters deep brown; all femora brown with apical yellow spot; fore and mid tibiae brown dorsally, bright yellow ventrally up to apex, hind tibia brown with irregular small yellow streaks, all tarsi yellowish brown (Fig. 111). Pubescence. Thick silvery bristles on clypeus, comparatively fainter setosity on outer side of scapal basin, fainter on gena; scattered pale brown setae on vertex; scattered long setae on mesoscutum, mesopleuron and scutellum, propodeum with longer setae; legs moderately setose; Gt 1 with moderately long setae at base, remaining metasomal terga with thicker and stouter brown setae. Head. As seen from above transverse, 1.43 × as long as wide (Fig. 115); mandible bidentate with identical teeth; clypeus markedly setose with surface well-hidden below thick silvery bristles, apico-medially produced forward (more so than in D. attenboroughi sp. nov.), forming slightly emarginated margin, longitudinal carina indistinct; antennal toruli almost touching one another and inner eye margin; scapal basin rugose reticulate, smooth just above antennal torulus; IOC distinct; distinct deep furrow present just above IOC, distinct longitudinal grove running from furrow towards anterior ocellus; frons matt, with well imprinted setigerous pits (Fig. 113); vertex with similar sculpture and thick short setae, gena with minute setigerous punctures; supra orbital furrow distinct; POD 1.1 × OOD (Fig. 115); scape with two carinae ventrally; relative lengths of scape: pedicel: flagellomeres I to XI (last) = 17: 3: 4: 3: 3: 3: 3: 3: 2: 2: 2: 2: 4. Mesosoma. Pronotum with conspicuous transverse carina dorsally and few rugulae laterally; pronotal collar with lateral corner rounded, medial notch indistinct, medio-posterior ridge conspicuous; mesoscutum and scutellum matt with scattered setigerous micropunctures; lateral mesoscutellar margin explanate, posterior margin finely sinuate; scutellum with apical margin coarsely foveolate; metanotum rugose, not separated from propodeum (Fig. 78); propodeum with coarse distinct rugae, interspaces smooth; hind femur of usual shape, as wide as basal width of Gt 1; hind tibia with four stout spines; mesopleuron matt with scattered setigerous micropunctures; metapleuron rugose (Fig. 117); fore wing moderately setose, with brown tinge apically (Fig. 118). Metasoma. Petiolate, with Gt 1 stout, width at stigmata narrower than width of hind femur; all terga matt black, immaculate, except Gt 5 with faint yellow spot laterally; Gt 1 4.07 × as long as wide, anterior third polished with distinct rugae, remainder matt, with very few setigerous micropunctae (Figs 119 & 120). Variability. Paratype body length 4.2 mm; posterior margin of clypeus truncate; macula on pronotal collar wide; Gt 5 with larger macula. Female. Unknown. Prey. Unknown. Etymology. The specific epithet is a commemorative, genitive noun in apposition taken from patronym Tsuneki after the late Dr. Katsuji Tsuneki in honour of his prodigious contributions to aculeate hymenopteran taxonomy.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
