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
Rejectaria atrax Dognin 1891
No full textRejectaria atrax Dognin, 1891 Habitus Fig. 16, 27. Male genitalia Fig. 54, 77–78. Narcaea atrax Dognin, 1891, Le Naturaliste 13: pp. 125–126. Type locality: Ecuador: Loja (Holotype ♂, USNM) Material examined. Type material: Narcaea atrax Holotype ♂. Ecuador: Environs de Loja Equateur SJ., Narcaea sp. n. “I have described the genus in the Biologia, Narcaea atrax Dgn, type, type figure 1894, Dognin Collection”, Type No. 32294 U.S.N.M., USNMENT00973692, USNM slide 148640 Diagnosis. Rejectaria atrax and R. splendida are differentiated from other species by the presence of fine, white, entire am and pm lines on the forewing, the absence of frosting in the median field, and the presence of chalky-white patches in the postmedian field. Rejectaria paratrax lacks whitish frosting and R. ritaashleyae lacks an am line. Supplement to original description. Head . Frons, vertex dark brown; male antennae setose-ciliate; male palpi (Fig. 27) predominantly brown with scattered white scales, overall shape squared, the 1 st and 2 nd segments forming right angles, 1 st segment turning upward at a 90˚ angle before meeting the 2 nd segment; 2 nd segment curving gently for most of its length before turning sharply backward, well above the head. Everted hair pencils tannish. Thorax. Wings (Fig 16)—(male, 24.5, n=2) FW with dark brown median field, heterogeneous pale frosting in basal and postmedial fields, frosting in the postmedial area concentrated in the subapical patch and towards the pm line where it meets the inner margin; st line faint a discontinuous series of white markings, terminal line a series of white dashes; finge brown; pm, st and terminal lines continue on HW. Legs (Fig. 31) — (Fig. 27) Predominantly chocolate brown, male foretibia cream-colored laterally; pronounced chocolate-brown tuft with scattered white scaling; female foreleg and midleg with additional white scaling at segments; incomplete cream-colored segmental bands on legs and at base of tibial spurs. Abdomen. Gray-brown above, concolorous with hindwing uppersides. Male genitalia. (Figs 54, 77, 78) Indistinquishable from splendida (below); valva also similar to that of paratrax in having uneven (as opposed to smooth) outer margin. Female genitalia. Unknown. Immature stages. Unknown. Biology. Unknown. Distribution. Ecuador Remarks. The male holotype of atrax from Ecuador may be conspecific with the Costa Rican syntypes of splendida based on habitus and genitalia, but since no other specimens are available for comparison and there are neither barcode nor larval data available, we have chosen to maintain both names.Published as part of Goldstein, Paul Z., Janzen, Daniel H., Hallwachs, Winnie & Proshek, Benjamin, 2022, New species in Rejectaria Guenée (Lepidoptera: Erebidae: Herminiinae) with a focus on the Cyclanthaceae-feeders, pp. 451-483 in Zootaxa 5087 (3) on pages 458-460, DOI: 10.11646/zootaxa.5087.3.4, http://zenodo.org/record/582694
