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
Increase in efficiency of training process of young sportsmen on the basis of the analysis of their readiness
No full text<p><strong><em>Abstract. Romanenko V., Veretelnikova N. Increase in efficiency of training process of young sportsmen on the basis of the analysis of their readiness. </em></strong><em>Article is devoted to a problem of creation of educational and training process at beginners. <strong>Purpose</strong>: to define the main directions of increase in efficiency of training process of beginners on the basis of the analysis of their readiness. <strong>Material and methods.</strong> Rational creation of training process at stages of long-term sports preparation is of great importance. It influences the level of interest of beginners in occupations, their sports progress, safety of the contingent in educational groups. In recent years at sports schools and clubs the competition between sports sections of single combats grew. For formation of steady interest at beginners in training occupations it is necessary to approach each athlete separately, to consider their psychophysiological and motive features of development. Use in training process of modern scientifically based techniques of training in physical actions, development of physical qualities, assessment of progress of training to increase efficiency of training process and will allow to solve the main objectives of a stage of initial preparation. In a research the following methods were used: tool method, pedagogical testing and methods of mathematical processing of experimental data. <strong>Results</strong>: On the basis of the analysis of level of readiness of beginners the main directions of their training process are defined. <strong>Conclusions</strong>: 1) Objective assessment of level of readiness of young athletes allows to reveal the lagging behind parameters and on the basis of it to pick up means and methods for their improvement. 2) The main directions of increase in efficiency of training process of beginners are defined, concern them increase in a share of exercises on development of coordination abilities, flexibility</em></p>

The research used tool method and methods of mathematical processing of experimental data. Video computer analysis is made with use of the special computer “Biomechanics” program developed at the Department of Combat Sports of Kharkiv State Academy of Physical Culture</em> <em>designed for mobile devices under control of iOS. <strong>Results</strong>: temporary characteristics of main technical and tactical connections of high level taekwondo practitioners and athletes with having brief experience in competitive bouts are received. The comparative analysis of the obtained temporary characteristics is carried out, the main differences and features of the offered TT</em><em>С</em><em> are defined. These differences testify to the insufficient level of high-speed and power abilities of athletes, drawbacks in techniques and can be used for selecting means and methods used in preparation of junior taekwondo practitioners. <strong>Conclusions</strong>: 1) temporary characteristics of main competitive actions of junior taekwondo practitioners and the qualified athletes are defined. 2) on the basis of the comparative analysis of temporary characteristics of competitive actions the drawbacks of training junior taekwondo practitioners are defined, to which the insufficient level of high-speed and power abilities and violation of ratio duration of phases of blows belong to. </em></p>
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
