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
Beden eğitimi ve spor öğretmenliği bölümünde okuyan öğrencilerin dört yıllık eğitim sürecindeki fiziksel ve fizyolojik özelliklerinin ıncelenmesi
No full textProblem Statement: Student candidates who want to be a Physical Education Teacher in Turkey should take special ability exams of Physical Education and Sports Schools. In this exam, it is required to have a high physical capability apart from a high level of special branch skills. For this reason, the students who pass and start their education at physical education and sports schools either have a good history of sports or they are active sportsmen or they have passed through a good training period. In other terms, they have high levels of physical and physiological capacity. But, the density of the curriculum at physical education teaching departments at Physical Education and Sports Schools, redundancy of theoretical courses which are defined and forced by Higher Education Council in Turkey to all the Physical Education and Sports Schools and from time to time the obligation to make a choice between school and active sportsmanship pull students away from active sportsmanship and regular training. After a dense curriculum program, the majority of students prefer education instead of sport activities and thus, when they reach their final year, they turn into sedentary people. This contradiction in the education of physical education teachers which is a model for the community and carries the task of selecting gifted people and directing people to sports for sustaining a healthy and quality life is thought-provoking. Purpose of Study: In this study, it is aimed to measure and evaluate some physical and physiological parameters of students attending physical education and sports schools from the first year on until the fourth year by taking the arguments given above. Methods: 70 male, 50 female and in total 120 students attending to Afyon Kocatepe University School of Physical Education and Sports took part in this study. Some physical and physiological parameters of the students were measured for three years in the Fall semester in November beginning from the first year on and in their final year, the measurements were made in the Spring term in May. Their weights, heights, body fat percentages, body mass indices and flexibilities, vertical jumps, anaerobic powers and aerobic capacities were identified with these measurements. Repeated measures analysis was used for statistical evaluation. The results were evaluated between 0,01 and 0,05 levels. Findings and Results: Body weights, BMIs, body fat percentages, flexibility levels, anaerobic powers and aerobic capacities of students who go through an intense and difficult exam to matriculate School of Physical Education and Sports are at levels of sportsmen. These performance levels of students decrease each passing year. These traits decline even to the levels of sedentary people in the fourth year. Conclusions and Recommendations: The students of School of Physical Education and Sports have an intense syllabus and the excess of theoretical courses prevent from regular training. Also, students in our country have to prepare for a tough theoretical exam after graduating university in order to be a teacher. This obligation moves them away from sporting activities in their free times remaining form school. In the light of this result, it is necessary to revise curriculums of Physical Education and Sports Schools in our country which train students to be teachers both for students, sportsmen and teaching staff
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
The effects of four weeks training on leptin levels in junior female judokas
No full textThe purpose of this study is to investigate the effects of four weeks judo training on plasma leptin levels. Twenty-five female national team athletes with a mean age of 18.12 +/- 1.12 years; body weight of 62.72 +/- 22.72 kg; body height of 164.28 +/- 7.28 cm, BMI of 23.17 +/- 6.28 kg/m(2); training experience of 6.56 +/- 5.44 years participated in this study. The data were collected from junior female judokas who trained six times in a week for two hours daily. Physical measurements and blood samples were taken before and after four weeks of training including technical, tactical and physical preparations. Body fat percentages were measured by using the Tanita Bioimpedance BC-418 (Tokio, Japan). Statistical Package for Social Science 15.0 (SPSS) was used to analyse the obtained results. Before and after the training, paired samples t-test was used to evaluate the differences between serum leptine and body fat percentages. Results of this study showed that pre-training serum leptin levels were significantly lower than post-training levels (p<0.01). There was also significant decrease in body fat percentages after four week training (p<0.01). Four weeks judo training results in a decrease in total body fat and serum leptin level in junior female judokas. It may be considered that lowered serum leptin levels were due to the decrease of the body fat percentage after four weeks training
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
