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
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
Tehuacania howdeni Endrodi 1975
No full textTehuacania howdeni Endrödi, 1975 (Figs. 1–5) Material examined: “ MEXICO: Puebla, Santa Maria Coapan; Junio, 2000. L. García” (1 female) (ITCV); “ MEXICO: Puebla, Santa Maria Coapan; Julio, 2000, L. García.” (1 female) (CABS); “ MEXICO: Puebla, Tlacotepec de Juárez, Santa Maria La Alta, 18 -VI-1998, 1960 m, luz fluor. V. Sánchez” (1 female) (MXAL); “ 20 m NW Tehuacan Pueb. Mexico, VIII. 10.61. [Edward] Greenwood” (1 male holotype) (CMNC). Description. Female (Figs. 1–4): Total body length 31.7–33.7 mm; maximum elytral width: 17.3–17.8 mm. Head, pronotum and elytra dark reddish black; legs and ventral region reddish black to almost black. Head: Clypeus strongly contracted, not reflexed; surface rugose; apex truncated. Frons with 2 small transverse protuberances, not connected; surface strongly punctate. Mandibles simple, emarginated; apex not incised. Surface of mentum with strong punctation to sparse smaller punctation, with long setae at sides, glabrous medially. Galea ventrally without setae, with dense setae dorsally. Antennae with 10 antennomeres, club short. Pronotum: broader than longer, convex; base bordered; sides curved; without tubercles; anterior marginal bead incomplete; punctures small, wrinkled at side and apical region; without setae. Prosternum: Prosternal process laminate. Elytra: shape longer than broad, with rows of small punctures; elytral sutural striae not well defined throughout its extension, with rows of small punctures. Metathoracic wings well developed. Legs: protibia tridentate, apical teeth triangular, closer together in relation to basal teeth, mesotibia and metatibiae triangularly dilated toward apex, both with transverse carina distinct and setose. Protarsi not thickened. Basal metatarsomere clearly enlarged. Abdomen: Pygidium convex with sparse micropunctation. Propygidium without stridulatory area; densely punctate with sparse, short setae. Genital plates (Fig. 3), ventromesial plates broad with shallow, circular impressions on surface, sides convergent, apex rounded with scattered setae; laterodorsal plates narrowed with apical border coarsely tridentate, without setae. Male (Fig. 5): Similar to female, except that the small transverse protuberances of the frons are slightly conical, with pointed apex. Basal border of last abdominal sternite weakly emarginate medially. Type locality: 20 mi NW Tehuacan, State of Puebla, Mexico (approximately 18 ° 24 ‘ N, 96 ° 50 ‘ W). Distribution: Known only from three localities in the Valley of Tehuacan, in the vicinity of the following towns: Tlacotepec de Díaz, Santa María La Alta and Santa María Coapan (Fig. 6). Biological data: This species inhabits xerophilous shrub located between 1,600–1,960 m in elevation. The adults have been collected sporadically at light traps in June, July and August. Feeding habits of adults and larvae are unknown. It is possible that the species are not commonly attracted to lights because their main activity occurs in the evening. Intense searching during day hours under rotten vegetal matter, on the stalks of plants, as well as with light traps did not turn up more specimens. The sites where the specimens were collected are located near the borders of the Tehuacan- Cuicatlan Biosphere Reserve (CONABIO-RTP- 121), which is well known for the richness of xerophilous endemic plants, mainly cacti (Arriaga et al. 2000). We hope that a large population of T. howdeni lives in the reserve. Remarks: Weak sexual dimorphism, lack of complex cephalic or pronotal structures and the lack of projections in the external border of the mandibles of T. howdeni may be indications of a primitive species of the Oryctini.Published as part of Bitar, Alberto & Morón, Miguel Ángel, 2009, Description of the female of Tehuacania howdeni Endrödi (Coleoptera: Scarabaeidae: Dynastinae: Oryctini), with a key to the genera of Oryctini from Mexico, pp. 65-68 in Zootaxa 2048 on pages 65-66, DOI: 10.5281/zenodo.18649
