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

Guiding ring 1.5 lip-widths from anterior end. The stomal wall anterior to guiding ring are much thickened. Odontophore 43-46 um, nearly equal to odontostyle length and provided with broad flanges at its base. Maximum width of flanges 7-8 um.

Tails 0.6-0.7 anal body-width long, convex-conoid with well developed anal muscles and two caudal pores on each side. Male Not found. Habitat and locality Soil around roots of Pinus satívus from Tang Marg, Srinagar, Jammu & Kashmir. Remarks De Man (1880) described this species as Dorylaimus macrodorus having a long odontostyle with small aperture, double guiding ring, odontophore with broad basal flanges. Thorne (1939) proposed a new genus Enchodelus for a number of species of Dorylaimus and Dorylaimellus with E. macrodorus as type species. Thorne (1. c.) stated that this species was cosmopoliton in distribution. Iairajpuri & Loof (1968) recorded a single female of this species from soil around the roots of apple from Srinagar, Jammu & Kashmir. Habitats and localities: i) Soil around roots of grasses from Municipal Gardens, Mussooríe. Uttar Pradesh. ii) Soil around roots of Il/Iarchantia sp., from Tallital, Nainital, Uttar Pradesh. iii) Soil around roots of Marchanria sp., from Tiphintop, Nainital, Uttar Pradeshi iv) Soil around roots of Marcharıtia sp.. from jeolikot. Nainital, Uttar Pradesh. v) Soil around roots of mosses from Pauri Road, Lansdowne. Garhwal, Uttar Pradeshl The present specimens were also collected in Srinagar. They agree fairly well with the description of E. macrodorus as given by Thorne (1939) and Jairajpuri & Loof (1968). However, they differ from the specimen previously collected from Srinagar in having longer body (L=1.47 mm) and more posterior vulva (V= 37). The values in parentheses are of single specimen of. E. macrodorus as given by Jairajpuri & Loof.Published as part of MAQSOOD AHMAD & M.
