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
Neosilba bifida Strikis & Prado, 2005, n. sp.
No full textNeosilba bifida n. sp. Material examined: Holotype: male, deposited in the Museu de Zoologia da Universidade de São Paulo, SP. Brazil; reared from Eriobotryia japonica (Thumb.) Lindl. (nêspera) São Bento do SapucaiSP, Brazil, 31 /01/ 1996, collected by Miguel de Souza Filho, kept in alcohol. Paratypes: 2, one kept in alcohol another mounted in microscope slide deposited in the Museum cited as above, derived from the same sample as the holotype. Description Male: body size 5.0 mm. Frons narrowed toward lunule. Head length/ width ratio 1.17. Lunule with 8 setulae 4 at each side; ocellar plate with 5 strong bristles, and 2 strong inter ocellar bristles below ocellar plate and 2 others above ocellar plate. Antenna with one prominent bristle in the second segment, first flagelomere with length/ width ratio 3.72 (0.82 mm: 0.22 mm); arista long and plumose (1.05 mm), longer than first flagelomere; arista length/first flagelomere length ratio 1.28. Palpus large and broad. Thorax: Mesonotum 1.6 mm long; anepisternum with 5 strong bristles and a cluster of 3 setae below the bristles. Scutellum margin bare, with 2 strong marginal basal bristles and 2 apical marginal bristles and a cluster of 4 marginal setae at each side and 2 setae between apical bristles; dorsum of thorax setulose with 12 strong bristles. Wings: 4.7 mm long, hyaline, with brownish veins and microtrichias; length/width ratio 2.30; calypteres white with white fringes and with about 12 long blackish setae at fold. Male terminalia: Epandrium short; as long as wide (1: 1); in lateral view surstylus is not visible, and has 6 prensisetae. Aedeagus filament fine and slender after “C” shaped base until apex, ending just after prensisetae and evenly tapered to apex (Fig. 1). “C” shaped base of aedeagus with no spicules but with a remarkable spinelike left bended structure in ventral view, arising from the distal portion of convex side of the “C” shaped base of aedeagus (Fig. 2 and 3). There may be some variation in length of the spinelike structure Female: unknown. Diagnosis: the most remarkable character in identifying N. bifida n. sp. is the spinelike structure, which is easily seen in ventral or lateral view of male terminalia. Taxonomic discussion: N. bifida n. sp. is very similar to N. glaberrima McAlpine & Steyskal externally, but lacks the hair arrangement in the last abdominal tergite; we believe it belongs to a group of undescribed species that has a complex structure in the convex side of the “C” shaped base of aedeagus, ending with the formation of a well defined spinelike structure. Distribution: Only known from São Bento do Sapucai, São Paulo, Brazil; this locality situated over 900 meters height. Biology: This species has been reared from Eriobotryia japonica (nêspera), and just a few individuals were collected from this fruit. The inclusion of N. bifida in McAlpine’s (1982) key to Neosilba species is suggested as follow: 6. Aedeagus short and broad, (Figs. 29 –30, 34– 35). Prosternum usually setulose.......... 7 Aedeagus slender. Prosternum always bare................................................................. 8 8 Aedeagus with a median lobe or a pair of teeth on thicker basal section, apex of filament not swollen or strongly S shaped........................................................................ 9 8 ’ Aedeagus with a spinelike structure arising from the distal portion of the convex side of the “C”shaped base, short and slender and two times as long as the “C” shaped base ...................................................................................................................... bifida n. sp. 8 ’’ Adeagus without a median of lobe or a pair of teeth on thicker basal section, apex of filament frequently swollen, flared or S shaped......................................................... 11Published as part of Strikis, P.

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
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
