Coenobita rugosus
No full textCoenobita rugosus The first stage crab (0.92–0.97 mm SL) has a whitish shield and brownish pigmented ocular acicles (Fig. 11 A– C). The pigmentation of the ocular acicles changes to dark brown in juveniles with an SL of> 1 mm after one month of age (Fig. 11 D–F, 12A, B, D, E). The upper edge of the shield is brown/dark brown in juveniles with an SL of> 1.3 mm after three months of age (Fig. 11 E, F, 12A, B, D, E). After four months of age (> 1.8 mm SL), the shield has a brownish stripe on the anterior lower margin of each side wall in some juveniles (Fig. 12 B, G–I) and the ocular peduncle of all specimens has a ventral brownish band (Fig. 12 B, C, F–I). The chelipeds and the second and third pereiopods of the first stage crab are reddish (Fig. 11 A, B); they vary in color pattern after four months of age, with brown bands on some segments (Fig. 12 A, D–I). The palm of the left cheliped has a brown stripe/patch with a large variation in area on the posterior middle portion (Fig. 12 F–I).Published as part of Hamasaki, Katsuyuki, Tsuru, Takuma, Sanda, Tetsuya, Fujikawa, Shunsuke, Dan, Shigeki & Kitada, Shuichi, 2017, Ontogenetic change of body color patterns in laboratory-raised juveniles of six terrestrial hermit crab species, pp. 521-545 in Zootaxa 4226 (4) on page 537, DOI: 10.11646/zootaxa.4226.4.5, http://zenodo.org/record/26513
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
