Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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

Ground colour sandy yellow, with abundant white or ash grey suffusion giving to moths a characteristic appearance. Wing pattern dark grey, prominent, submarginal field of the fore wing is covered with dark yellowbrown to chestnut scales whereas in hind wing it is brighter dark yellow to ochre-yellow. Wing serration distinct in hind wing, but marginal teeth are short and massive, forming sometimes very short bifurcate tail; in fore wing, medial projection may be double and the falcate part is smooth. Female similarly patterned, a bit darker, with the same kind of serration and a short bifurcate tail. Male genitalia (Fig. 26). Uncus lobes curved, lyre-shaped, with rounded apices; valvae short and broad; harpe strong, rather short and covered with dense spines on its distal third; right apical spur rather slender and pointed. Female genitalia as illustrated (Fig. 28). Diagnosis. Small size, contrasting ‘grey-scaled’ coloration, prominent wing pattern and short but distinct wing serration makes identification of the species rather easy. From the similar and sometimes sympatric O. yandu it differs being paler, a bit smaller, with shorter wing serration. Bionomics. The population of the species of the type locality is native to montaine forests where it inhabits altitudes of 1300–2600 m but more commonly 1500–1800 m, and is on the wing from late April to early September, develops 1–2 generation(s) depending on the altitude. Lowland populations (of Hunan, Guangdong, Hainan) are known develop two generations per season and is known from May to August. Distribution (Fig. 34). Mountains of Shaanxi, Jiangxi, Hubei, also known from N and NW Sichuan, Hunan, Guangdong and Hainan. PLATE 4. Figs 30–33. Biotopes. 30.

The present new species is very close to P. (T.) decematoguttatum (Tokunaga), P. (T.) napahaiense Zhang & Wang sp. n. and P. (T.) mengmanense Zhang & Wang sp. n. in male hypopygial morphology that the anal point bears two dorsal lobed lamellae. We must be very careful when we observe above 4 species under microscope, because the dorsal lobed lamellae is transparent and easy to ignore in dorsal view. The above 4 species show a bit difference in wing markings and the length of lateral projection of anal point; Song et al. (2016) have certified these bit differences can result in inter-specific divergence by molecular data. Wang (2000) had wrongly identified some specimens of P. (T.) bilamella Zhang & Wang sp. n. collected from Ningxia Autonomous region as P. (T.) pullum (Zetterstedt).Published as part of Zhang, Ruilei, Song, Chao, Qi, Xin & Wang, Xinhua, 2016, Taxonomic review on the subgenus Tripodura Townes (Diptera: Chironomidae: Polypedilum) from China with eleven new species and a supplementary world checklist, pp. 1-53 in Zootaxa 4136 (1) on pages 10-12, DOI: 10.11646/zootaxa.4136.1.1, http://zenodo.org/record/39978
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
