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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

A full taxonomic treatment of species from the subgenus Chrysopteron (to which M. formosus belongs) has been published recently (Csorba et al. 2014). To avoid repetitions, we outline hereafter only the main distinguishing characters of the two species living in Taiwan and China (M. formosus and M. rufoniger). All species classified in this subgenus are phylogenetically part of the Ethiopian Clade (Csorba et al. 2014) and constitute a robust, monophyletic clade (Fig. 3). Following Csorba et al. (2014), the population of Taiwan (being significantly larger than their continental counterparts) is considered here as a distinct subspecies, M. formosus flavus. Distribution. M. formosus is a rare, but relatively widespread species, found from Afghanistan, along the foothills of the Himalaya (Csorba et al. 2014) east to Jiangxi province in China (Jiang et al. 2010), and Taiwan. Measurements. See Table 4 for measurements of the Taiwanese subspecies, M. f. flavus. Measurements for the nominal subspecies are given in Csorba et al. (2014). External morphology. This spectacular, relatively large Myotis has a unique cottony and yellowish fur, both above and below, the dorsal parts being only slightly darker at the hair tips (i.e., no ”smoked” aspect of fur as in M. rufoniger). The wing membranes are parti-colored, with a characteristic orange (along bones) and black patterning (see pictures in Lin et al. 2004). The uropatagium is essentially orange, as are the ears (unlike in M. rufoniger, which has conspicuous black margins to the ears) and face. Thumbs and hairy feet are also largely orange, except close to the claws, which are strong and black. Wings are attached to the base of the outer toe. Skull morphology. The skull is large, with massive canines and strong molars. The second upper premolar is much smaller, less than half the size of the first, and is usually completely displaced lingually from toothrow and thus invisible in side view (Fig. 8 c). The posterior parts of the braincase are high and globose, with very weak or no occipital or lambdoid crests (unlike in M. rufoniger, which has a more angular skull and marked crests). Natural History. This beautiful, but rare bat is known from few specimens, and owing to its large distribution across Asia is likely to have different ecologies throughout its range. In Taiwan, it is found exclusively in the lowlands, where it roosts either among tree foliage (Swinhoe 1870; Chen et al. 2010), or in buildings (Lin et al. 2004). In both situations, the bats are fully exposed to the light and seem to rely on their particular coloration to avoid predation. They occupy the breeding colonies (which may number up to several hundred individuals) between March and July. In October, they disappear from the breeding colonies to hibernate in unknown winter roosts.Published as part of Ruedi, Manuel, Csorba, Gábor, Lin, Liang- Kong & Chou, Cheng-Han, 2015, Molecular phylogeny and morphological revision of Myotis bats (Chiroptera: Vespertilionidae) from Taiwan and adjacent China, pp. 301-342 in Zootaxa 3920 (1) on pages 334-335, DOI: 10.11646/zootaxa.3920.2.6, http://zenodo.org/record/28792
