Calliderma emma Gray 1847
Calliderma emma Gray, 1847 Fig. 2 A Calliderma emma Gray 1847: 193; 1866: 6, pl. 15; Perrier 1894: 337; Liao and Clark 1996: 93 Pentagonaster (Calliderma) emma Perrier 1875: 226 (1876: 41) Calliderma spectabilis Fisher 1906: 1058; Chave and Malahoff 1998: 86; Liao and Clark 1996: 93; Mah 1998: 67 Taxonomic comments. Liao and Clark (1995) distinguished between Calliderma spectabilis Fisher 1906 and C. emma Gray 1847 on the basis of presence/absence of sharp spines on the radial abactinal plate regions (spines present on C. spectabilis). Liao and Clark (1995) argued that differences between the two species were slight and that the radial abactinal spines in C. emma were artefactually absent, thus removing the most significance difference between the two species. Examination of C. emma / C. spectabilis specimens, further supports their hypothesis that the two species are synonyms. Liao and Clark’s (1995) synonymy is adopted herein. In situ observations. Although not observed feeding, Calliderma occurs widely and is a subject of some fossil study (e.g., Villier et al. 2004) and as such, its living in situ life mode is considered herein. Calliderma emma [called C. spectabilis by Fisher (1906), see taxonomic note] is observed in many HURL images of the Hawaiian deep-sea benthos. All of the images observed show individuals on fine to coarse grained sediment in a diversity of current regimes (e.g., Fig. 4 A). None were observed on hard bottoms. Rays of this species were always splayed out on the bottoms with the arm tips upturned into the water. Only individual animals were observed in images reviewed with no other C. emma individuals present within the field of view. One image (M- 211 -036) showed C. emma in relatively close proximity (within 2 feet / 1 meter) distance to multiple aspidodiadematid echinoids but no interaction was evident (Fig. 4 A). Occurrence.

Calotes emma Gray, 1845 (Squamata: Agamidae): range extension and new addition to the reptilian fauna of Tripura, northeast India
Two new records of Calotes emma Gray, 1845, are reported from Srirampur and Homnpui in the state of Tripura, northeast India. These records are the first from Tripura. Present locality records extended the known distribution of C. emma in Southeast Asia
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
