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
Sarcophaga (Sarcorohdendorfia) narabondxii Geisler & Pape 2023, sp. nov.
No full textSarcophaga (Sarcorohdendorfia) narabondxii sp. nov. Figs 13–14 Type material: Holotype ♁: LFloridaI / SolomonIs / Mar 1945 / GEBohart. Terminalia glued to a separate piece of cardboard pinned under the specimen. Deposited in USNM. Type locality: Solomon Islands, Central Province, Nggele Islands [= Florida Islands]. Etymology: The name narabondxii (from Narabond = a fictional nation, and xii = Roman numeral for twelve) was chosen as an homage to the players that portray the fictional group of soldiers from the twelfth company of the fictional nation Narabond, which is part of the Danish live-action roleplaying universe Niraham and the community “Nordlenets Saga ”. The junior author (LG) is an active member, and soldiers will dress in black and yellow colours reminiscent of the present species. Suggested pronunciation: n/ɑː/r/ɑː/bonds/ɪaɪ/. Description: Male—Head: Width of frons at narrowest point 0.04 x width of head (n = 1). Tomentum bright yellow across entirety of face with greyish spot on the post-gena and a black patch inside the ocellar triangle. Frontal setae equally strong from vertex to the upper part of parafacial plate, stretching past lunule and all the way to the end of the frontoorbital plate. Ocellar triangle with scattered setulae, ocellar setae equal to the weakest of the frontal setae. Inner vertical seta stronger than strongest frontal setae, outer vertical seta approximately 0.5 x length of inner vertical seta. Antenna with black scape and pedicel, golden brown postpedicel with golden brown arista. Palpus black. Vibrissa well developed [judged from the socket, the seta itself has been lost]. Genal and postgenal setae yellowish. Thorax: Yellow tomentum, matching colour of head; dorsally with three black stripes, middle stripe running from presutural scutum to approximately 0.5 of the length of scutellum, lateral stripes running from presutural to 0.9 of the length of postsutural scutum. Prosternum with black setae laterally. Chaetotaxy: acrostichals = 0+0, dorsocentrals = 5+2 (one broken but socket remaining), intra-alars = 2+2, supra-alars = 2+3, postalars = 2, anterior postpronotal = 0, basal postpronotal = 2, basal scutellars = 1, subapical scutellars = 2, apical scutellars = 1, discal scutellars = 0. Legs: Brown with greyish yellow area posteriorly on fore femur. Hind tibia with long and strong setosity along posterior surface. Wing: Veins brown with cubital vein and anal veins fading distally. Wing membrane hyaline, subcostal and discal cell with brown tint. Alula whitish to light brown. Upper and lower calypter whitish with yellow edge. Vein R4+5 with dorsal setulae at base, cell r4+5 open at wing margin. Abdomen: T1+2 black with two lighter grey spots on each side of median line, T3–5 with yellow tomentum except for black anterior bands; black median stripe reaching T5. Median marginal setae present on T4 and T5. Posterior margin of ST4 with patch of densely set short, bristly setae on a raised ‘hump’ covering about a third of the posterior margin. Terminalia: Cercus gently curved, with dorsal surface equipped with several robust setae in the middle. Hypandrium with posterior margin folding downwards as a pair of rugose or striated lobes. Pregonite deeply split, with larger tip blunt; postgonite tapering, with sigmoid anterior margin. Juxta tapering; vesica broad, with subapical tooth on a long, slender ‘neck’, apically with blunt tip; lateral stylus at least twice as long as juxta, with distal fourth partly membranous and without serration along the concave surface. Remarks: The holotype label gives the locality as “LFloridaI”, but the initial L is here interpreted as an error. The US navy had a base on Nggela Sule, which is the larger of the two main islands often referred to as Florida Islands (United States 1947), and George E. Bohart probably collected the specimen when deployed there as a medical entomologist (Entomological Society of America 2011). Morphologically S. narabondxii sp. nov. is most similar to S. isorokui (Shinonaga) but separable by the features given in the key. The sparse current material would indicate that S. narabondxii sp. nov. is found only on the Nggela Islands, while S. isorokui is restricted to Bougainville Island more than 500 km to the west.Published as part of Geisler, Lucas & Pape, Thomas, 2023, Two new species of the ' Big Yellows' (Diptera: Sarcophagidae: Sarcophaga), pp. 190-202 in Zootaxa 5311 (2) on pages 195-197, DOI: 10.11646/zootaxa.5311.2.2, http://zenodo.org/record/809418
