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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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 textIn 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.

Scutellar shield triangle, with slightly rounded lateral margins, finely and densely punctated, but with smooth midline. Elytra widest at middle. Lateral carina (dorsal surface of epipleura) and humeral angles very wide, completely visible dorsally. Punctures in striae elongate merged in interrupted deep furrows. Interstriae flat, with simple and weak transverse wrinkles coming from strial punctures, but not coriaceous, without dense irregular micro-wrinkles among punctation. Epipleura not reaching, and epipleural inner carina reaching elytra apex. Punctation of interstriae fine and sparse. Suture finely beaded at apical third of elytra.

Genitalia (Figs. 1D–F). Aedeagus ‘nalassoid’ (Nabozhenko 2005); baculi of median lobe wide, connected (Fig. 1D). Inner sternite VIII with rounded blades and dense setation of long setae. Spiculum gastrale with thin rods and long common stem; blades (derivates of tergite IX) triangle, with sclerotized outer margins. Body length 8–11 mm, width 4–4.3 mm. Female (Fig. 1B). Measurements: PH —1.67; P w P l —1.15; E l E w —1.47; EH w —2.23; EP w —1.33; EP l —2.26. Body robuster, more bluish, pronotum with greenish-violet tint, disc of pronotum more flattened, elytra longer, protarsi slightly narrower than in male. Body length 11–11.2 mm, width 4.5 mm. Etymology. The name derives from Turkish “mavi” (blue) and emphasizes the bluish colouration of the dorsum of the new species. Differential diagnosis. This new species differs from all congeners by the bluish dorsal surface of the body (Figs. 1A,B), the pronotum widest at anterior half (Figs. 1A,B) (at middle or behind the middle in other congeners), and wide merged baculi of the median lobe of the aedeagus (Fig. 1E). It is similar to T. pentheri (Reitter, 1905) and T. petrophilus Keskin, Nabozhenko & Alpagut Keskin, 2017, which also have the punctation of elytral intervals fine and sparse, with the puncture diameter 3–5 times as less as interpuncture distance. Turkonalassus mavi sp. n. additionally differs from the first species by not thickened male antennomeres 4–8 (which are thicker than three apical antennomeres in T. pentheri) and strial punctures merged in furrows (separate in T. pentheri). The new species additionally differs from the latter taxon by much denser and coarser punctation of round punctures (punctures smaller, sparse and elongated on lateral sides in T. petrophilus). Bionomics and trophic relations. The species was collected in old Pinus nigra J.F. Arnold forest with shrub undergrowth of Juniperus communis L. The presence of this juniper shrub undergrowth is crucial factor for all species of Turkonalassus. Usually, beetles hide in thickets of J. communis, and at night they go out on tree trunks or stones. Adult beetles of T. mavi sp. n. were active at night since 20:30 on trunks of Pinus nigra. Host lichen is Pseudevernia furfuraceae (L.) Zopf (Parmeliaceae Zenker) (Fig. 2).Published as part of Nabozhenko, Maxim V., Keskin, Bekir, Keskin, Nurşen Alpagut, Gagarina, Ludmila V. & Nabozhenko, Svetlana, 2021, Two new species and new records of lichen-feeding darkling beetles (Coleoptera: Tenebrionidae: Helopini) from Turkey with notes on bionomics and trophic relations, pp. 69-86 in Zootaxa 5057 (1) on pages 71-73, DOI: 10.11646/zootaxa.5057.1.4, http://zenodo.org/record/558553
