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
Eurydactylodes Wermuth 1965
No full textEurydactylodes Wermuth, 1965 Content. Eurydactylodes vieillardi (Bavay, 1869), E. symmetricus (Andersson, 1908), E. agricolae Henkel & Böhme, 2001, E. occidentalis, Bauer, Jackman, Sadlier & Whitaker, 2009 (Fig. 3 E). Type species. Platydactylus vieillardi Bavay, 1869 by monotypy [as type of Eurydactylus Sauvage, 1878; this name was preoccupied by Eurydactylus Laferté, 1851 = Coleoptera] Diagnosis. Eurydactylodes is distinguished from all other New Caledonian diplodactylid gekkotans by the following combination of characters: body size small (to 60.3 mm SVL); neural spines of trunk vertebrae elongate, body laterally compressed, six or seven inscriptional ribs, dorsal body scalation consists of enlarged, smooth, flattened scales; dorsal head scales enlarged to greatly enlarged; a postlabial slit present, confluent or not with subauricular groove; endolymphatic sacs expanded extracranially; margins of jaws and limbs with folds of skin; subdigital lamellae undivided or with irregular divisions; claw of digit I of manus and pes lies between a pair of separate terminal subdigital scansors; precloacal pores in males in 3–5 rows sometimes extending onto base of thighs (50–68 pores in total); original tail (100–115 % of SVL) with distal adhesive subcaudal lamellae and possessing caudal glands and a “tail-squirting” mechanism; tongue and mouth lining yellow to orange; dorsal color pattern grayish, cream, tan, or beige with darker transverse bands or markings; venter white. Distribution. Eurydactylodes has been recorded from the Îles Belep (Île Art and Île Pott only), Île Yandé, the Grande Terre and Île des Pins, but has not been found on the Loyalty Islands or any smaller satellite islands. Remarks. See Bauer and Henle (1994); Bauer and Sadlier (2000), and Bauer et al. (2009) for additional details about this genus.Published as part of Bauer, Aaron M., Jackman, Todd R., Sadlier, Ross A. & Whitaker, Anthony H., 2012, Revision of the giant geckos of New Caledonia (Reptilia: Diplodactylidae: Rhacodactylus), pp. 1-52 in Zootaxa 3404 on page 16, DOI: 10.5281/zenodo.21173
Paniegekko Bauer, Jackman, Sadlier & Whitaker
No full textPaniegekko Bauer, Jackman, Sadlier & Whitaker gen. nov. Content. Paniegekko madjo (Bauer, Jones & Sadlier, 2000) (Fig. 3 D) Type species. Bavayia madjo Bauer, Jones & Sadlier, 2000, here designated. Etymology. The generic name is derived from the Panié massif, the dominant landform of northeastern New Caledonia, and gekko, from the Malay ‘gekoq’, onomatopoeia of the call of the species Gekko gecko and the common name to all limbed gekkotans. A Sri Lankan origin for the word gekko, derived from the Sinhalese word ‘gego’, is also possible (de Silva & Bauer 2008). The name is masculine and should be pronounced “Pa-nē-āgekko.” The two known localities for this monotypic genus are Mt. Ignambi and Mt. Panié, both part of the Panié massif. Definition and Diagnosis. Paniegekko may be distinguished from all other New Caledonian diplodactylid geckos by the following combination of character states: body size moderate (to 75mm SVL), head large, tail slender and elongate (> 110 % SVL); dorsal scalation granular, homogeneous; body without extensive skin webs or flaps; expanded subdigital lamellae under all toes; subdigital lamellae of digits II–V of manus and pes unpaired basally and divided distally; claw of digit I of manus and pes positioned lateral to a single, undivided apical lamella; precloacal pores in two or more rows in males, longest row extending well onto thighs (50 or more pores total); dorsal coloration pattern brown with transverse chevrons; venter dull grayish, never yellow. Distribution. Paniegekko is known only from Mt. Ignambi and Mt. Panié in northeastern New Caledonia. Remarks. See Bauer and Sadlier (2000) for more information on P. m a d j o. Erection of a new genus for Bavayia madjo was necessitated to maintain the monophyly of Bavayia (see above).Published as part of Bauer, Aaron M., Jackman, Todd R., Sadlier, Ross A. & Whitaker, Anthony H., 2012, Revision of the giant geckos of New Caledonia (Reptilia: Diplodactylidae: Rhacodactylus), pp. 1-52 in Zootaxa 3404 on page 16, DOI: 10.5281/zenodo.21173
