The purpose of this study was to develop a spin serve training model in court tennis based on kinovea. This type of research was Researched and Development (r&d) used
researched subjects tennis player 14-21 years old, tennis coaches, and tennis practitioners. The research steps used include mini researched, development planning, initial product development, initial field tests, product revisions, main field trials, operational product revisions, operational field trials, and final revisions. The researched instrument for the spin service motioned process used was to make an assessment of the spin service motioned
process with the results of the validity of each instrument aspect > 0. 3 and reliability 0. 552 > 0. 3. Product testing was carried out internally and externally, and data analysis used a mixed method. At the planning stage of product validation used was expert judgment. The external validation test was carried out at the small group trial stage and the large group trial used the questionnaire method as the basis for product improvement. In the final stage, the product effectiveness test was carried out using the pretest-posttest controlled group design method. This study produced a training model product of 30 motioned patterns for the spin service exercise model with the results of an internal test from the expert judgment that the product was feasible and could be used as a spin service exercise model, with an
average value of 88. 19%≥75%. The results of the external test in the small group trial obtained the results 84. 5%≥75%, while the results of the analysis of the large group trial were 86. 7%≥75%, and the results of the operational field test obtained an average value of 90. 5%≥ 75%. The results of the product effectiveness test obtained the results of a t value of 13. 36, df = 58, and the value of sig. 0. 000 (p<0. 05), thus the product stated that the
kinovea-based tennis spin serve training model was more effective than conventional training, and effective NGain_score 66,5%

Temuan tersebut sebagai bahan tindak lanjut untuk mereposisi tulang belakang yang telah mengalami kelainan. Kata Kunci: vertebrae, kyphosis, lordosis, skoliosi
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
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
