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
Strongylophthalmyia bifasciata Yang & Wang 1992
No full textStrongylophthalmyia bifasciata Yang & Wang 1992 (Fig. 11) Strongylophthalmyia bifasciata Yang & Wang, 1992: 447 (male, female). Material examined. ♂, China, Sichuan, Baoxing, Dengchigou, 1600–1800 m, 30°22¢ 32²N, 102°49¢ 44²E, 13.VI.2014. J.Hájek, J. Růžička, M. Tkoč lgt. (NMPC). Since there is very little information on Chinese continental species, below we provide a description of S. bifasciata and a revised fragment of our key (Galinskaya & Shatalkin 2016) that will allow for determination of our new species, including S. strigosa n. sp., and other species of the S. trifasciata species group. Description. Male. Head. Frons black, anteriorly with yellowish matte band, width of the band equal to half of distance from fore edge of frons to fore ocellus; frontal index = 2.2. Occiput black shining in dorsal half; yellow in ventral half. Face, gena and postgena yellow. Antenna yellow, scape and pedicel brownish-yellow. Flagellomere small, rounded. Arista white, covered with short white setulae. Mouthparts yellowish; palpus yellowish, apically brownish. Two orbital setae, one ocellar seta, one postocellar seta, one inner and outer vertical setae, seven setulalike short frontal setae. Thorax black, metathorax matte, with thin punctation, covered with sparse, pale setulae; with two lateral crescent-like yellow bands, extending from transverse suture to scutellum (like in some specimens of Chyliza, Psilidae). Postpronotum yellow. Pleura black shining; propleuron and prosternum yellow. Scutellum black matte, metanotum black shining. Two dorsocentral setae, two notopleural setae, one supraalar seta, one postalar seta, one anepisternal seta, one stout apical scutellar seta. Legs yellow; mid femur with weak apical darkening, mid tibia in middle 1/3 brownish laterally; hind femur with developed apical ring; hind tibia brownish laterally in middle 3/5. Hind coxa with small disc-shaped process on inner surface (Fig. 11 e). Wing with large but very weak apical darkening: its proximal margin almost reaches level ov vein R2+3 and with median transverse band on level of dm-cu. Costal index = 2. Discal index = 1.5. Medial index = 0.6. Vein r-m inserted at basal 2/5 of discal cell. Cell bm about 0.43 times as long as cell dm. Calypter yellowish with fan of very long yellowish setulae on margin. Halter with whitish knob and brownish stem. Abdomen laterally yellow, dorsally black; abdominal tergite five black shining. Lengths. Body, 3.8 mm; wing, 3.2 mm.Published as part of Galinskaya, Tatiana V. & Shatalkin, Anatoly I., 2018, Seven new species of Strongylophthalmyia Heller, 1902 (Diptera: Strongylophthalmyiidae) from the Eastern Palaearctic and Oriental Regions with notes on peculiar rare species, pp. 113-135 in Zootaxa 4402 (1) on pages 130-132, DOI: 10.11646/zootaxa.4402.1.5, http://zenodo.org/record/120826
Cryptanalysis of Yang-Wang-Chang’s password authentication scheme with smart cards
No full textIn 2005, Yang, Wang, and Chang proposed an improved timestamp-based password authentication scheme in an attempt to overcome the flaws of Yang-Shieh’s legendary timestamp-based remote authentication scheme using smart cards. After analyzing the improved scheme proposed by Yang-Wang-Chang, we have found that their scheme is still insecure and vulnerable to four types of forgery attacks. Hence, in this paper, we prove that, their claim that their scheme is intractable is incorrect. Also, we show that even an attack based on Sun et al.’s attack could be launched against their scheme which they claimed to resolve with their proposal
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
