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
Palaeothespis leigongshanensis Ge & Chen, n. sp.
No full text4 Palaeothespis leigongshanensis Ge & Chen n. sp. (Figs. 1–11) Diagnosis. The new species, P. leigongshanensis, clearly differs from P. oreophilus, P. pallidus and P. stictus in the following characters: The surface of pronotum rough with more tubercles, especially in the female; the tegmina with more dark brownish spots and legs with black or dark green spots. Description. Male Holotype (Figs. 2, 4, 6, 8, 10): Head: Head narrowly transverse, scarcely broader than the pronotum, vertex flat with small post-ocular humps. Ocelli small, a little tubercle shaped and directed to the front. Eyes large, somewhat projecting forward. Frontal shield (sclerite) with strongly arcuate margin and some small black spots. Antenna long, thin, and more ciliate (Fig. 10). Thorax: Pronotum short and yellow brownish with more disk-like tubercles, those tubercles are small on the prozona surface and there is a pair of very large tubercles situated near the transverse sulcus (between prozona and metazona). Metazona with two pairs of large tubercles, tubercles situated near transverse sulcus remarkably larger than those situated near the basal margin of metazona, lateral margins with more small denticles. Supra-coxal expansion moderate but distinct (Fig. 2, 4). Tegmina extending beyond the tip of the abdomen long and narrow, with more large or small black spots. Veins parallel and closely spaced with two rows of large regular cells; costal field narrow with black spots. Wings transparent, with scatterred dark brownish spots, except in the middle area and extending beyond the apex of tegmina. Legs distinctly slender. Fore coxae more or less shorter than pronotum, fore femora about the same length of the pronotum and fairly slender with 4 discoidal spines, 4 external spines and 11 internal spines. Middle and hind legs long, slender, with dark spots, and internally somewhat greenish. Abdomen: Brownish yellow and slender with small lobes on the lateral sides of each segment. Measurements: Total length to tegmina tips: 36.0 mm, total length to wing tips: 39.0 mm, head width: 3.7mm, pronotum length and width: 6.5 and 3.5 mm respectively, prozona 2.9 mm, metazona 3.6 mm, fore coxae: 6.0 mm, fore femora: 7.5 mm, antennae: about 21mm. FIGURES 1–5. Palaeothespis leigongshanensis Ge & Chen n. sp., Fig. 1, pronotum of female; Fig. 2, pronotum of male; Fig. 3, pronotum of female; Fig. 4, pronotum of male; Fig.5, 1– 4 th segments of female abdomen, left side. Scale bars: Figs. 1–2 = 1mm; Figs. 3–4 = 2mm, (1–2. dorsal view; 3–5. lateral view.) Female Paratype (Figs. 1, 3, 5, 7, 9, 11): Head: Body brownish, with black and dark green spots on the legs, head broader than that of male with large post-ocular humps. Ocelli bigger than in male and antennae thin and short (Fig. 7, 9, 11). Thorax: Pronotum wider and with more prominently large tubercles especially at the each side of transverse sulcus, three pairs of tubercles situated on each side of the median, remarkably bigger than tubercles in the male; beside theses large tubercles, more disk-like tubercles distributed on the prozona surface and near sulcus, denticles on the lateral margins somewhat blunter than those in the male (Fig. 1, 3, 5). Tegmina and wing-pads fused to the thoracic segments (Fig. 7, 11). Abdomen: Central dorsal portion of the second, the third and the fourth abdominal segments produced into large foliaceous lobes; lateral dorsal portion with more fingerlike tubercles (Fig. 5). The lobe on the third segment is bigger than those on the second and fourth segments. Measurements: Head width: 4.8 mm, pronotum length and breadth: 7.2 and 5.0 mm respectively, prozona 2.8 mm, metazona 4.4 mm, fore coxae: 6.5 mm, fore femora: 7.8 mm, antenna: about 5.0 mm. Material examined. Holotype ɗ: Leigong Mountain National Natural Reserve, Leishan County, Guizhou Province, China, 13.IX. 2005, Qiong-Zhang Song. Paratype Ψ: Same locality as for holotype, 14.IX. 2005, Zhi-Jie Wang. Etymology. This species is named after the type locality, Leigongshan National Natural Reserve, Leishan County, Guizhou Province. Discussion. Unfortunately, we did not find the ootheca of this new species, but ootheca of P. s t i c t u s Zhou & Shen was obtained by keeping the female in laboratory for several days. The ootheca of this species is very small with about 15– 20 eggs, so the population density is likely to be low and it is very difficult to find specimens in the field.Published as part of Ge, De-Yan & Chen, Xiang-Sheng, 2008, Review of the genus Palaeothespis Tinkham (Mantodea: Thespidae), with description of one new species, pp. 53-58 in Zootaxa 1716 on pages 55-56, DOI: 10.5281/zenodo.27415
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
