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
Innervation of the Teeth
Get PDFThe combination of methods described in the thesis to demonstrate the nerves of the dental pulp gave rapid and consistent results which were superior to those obtained by previously described processes. In the author's experience, the great stumbling-block to the successful demonstration of pulpal nerves was the harmful effect of the acid used to decalcify the dentine. The ability of chelating agents to perform at neutral or alkaline pH suggested that the tooth might be decalcified without harm to the staining affinities of the pulpal nerves. The selection of an alkaline pH actually improved the selectivity of the silver method employed and was later discovered to be based upon an accepted method of improving silver impregnation. The success of the methods adopted permitted the observation of the pattern of distribution of the nerve fibres in a large number of permanent teeth from patients of all age groups. The author was able to demonstrate that nerve fibres were present in the odontoblast layer and in the predentine zone of uncalcified dentine matrix. The affinity of the inner border of the calcified dentine for the silver stain prevented the fine terminal nerve fibres from being easily followed beyond this layer. There was, however, ample evidence in support of the belief that nerve fibres did extend into the layers of calcified dentine. It is believed that the majority were calcified within the intertubular matrix. An occasional nerve fibre may have been enclosed beside the dentinal process of an odontoblast and, by virtue of its intra-tubular position, may have escaped the wave of calcification which passes through the intertubular matrix. The attempt which was made to demonstrate the presence of nerve fibres in the dentine matrix by means of the electron microscope was unsuccessful. Nevertheless the author still believes that it will be possible to demonstrate silver impregnated nerve fibres within the predentine zone and so prove conclusively the relationship between the nerve fibres and the collagen fibres of the dereine matrix. He also believes that the question of the presence of fine intratubular nerve fibres (described as being 0.2mu in diameter) within the calcified dentine matrix will only be satisfactorily proved or disproved by evidence from the electron microscope. In the numerous electron micrographs of the dentinal tubules in cross-section from areas where fine intratubular fibres have been described, the author was unable to observe any appearance which might confirm their existence
