Full text linkThe problem of the research was student’s lack forehand drive ability that resulting less points obtained while playing or hitting the ball. This research aimed to  identify  factors that causally and positively effecting the student’s forehand drive performance, namely back swing and forward swing phases. This study involved 31 male student’s who learning tennis subject in Sport Science Faculty, Padang State University. The samples tested using Broer-Miller-Tennis Test, and observed by judge. The data was analyzed by using Regression Analysis utilizing IBM SPSS software. To find out the causal factors which independently and dependently influence each variable, it is used the significance level <0.05 The results shos that Backswing had significant and positive effect on the accuracy of the forehand drive (p <0.05) . The significance level was p <0.05 or H0 was rejected. Furthermore, Forwardswing had significant and positive effect on the accuracy of the forehand drive (p <0.05) or H0 is rejected.  The results of the study show that there is a positive causal effect of backswing and forwardswing on athlete's forehand drive performance

No full textKarate athletes must master mawashi geri. To maximize athlete performance, Resistance and Plyometric Training Methods must be used. This study examines how resistance and plyometric training affect Mawashi Geri's proficiency. Simalungun junior karate practitioner Putera Dojo Tako. A 2x2 factorial experimental design is used in this investigation. The study included 32 Simalungun-based junior karate athletes from Putera Dojo Tako. Grid concentration and mawashi geri kicking proficiency tests were used. Two-way ANOVA and the Tukey test were used to analyze the data. The research shows that resistance and plyometric training improve karate contestants' mawasahi geri kicks. Next, strength training and plyometric training affect karate athletes' mawasahi geri kick performance. At Dojo Tako in Simalungun, male junior karate participants' mawasahi geri kicks varied, especially when performed with attention and passion. Male junior karate athletes at Dojo Tako, Simalungun Regency, who received resistance and low-intensity plyometric training showed variances in mawasahi geri kicking proficienc
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
Pengaruh motivasi belajar, kemampuan motorik lingkungan terhadap hasil belajar pendidikan jasmani olahraga dan kesehatan
No full textRendahnya hasil belajar pendidikan jasmani olahraga dan kesehatan siswa dapat disebabkan oleh berbagai faktor determinan diantaranya adalah motivasi belajar, kemampuan motorik, dan lingkungan sekolah. Tujuan dari penelitian adalah untuk menganalisis pengaruh motivasi belajar, kemampuan motorik dan lingkungan terhadap hasil belajar pendidikan jasmani olahraga dan kesehatan siswa. Penelitian ini menggunakan metode kuantitatif. Sampel dari penelitian ini sebanyak 120 orang siswa kelas XI di SMA N 2 Kota Tanjungpinang. Teknik pengambilan sampel yang digunakan adalah teknik random cluster sampling. Data dikumpulkan dengan menggunakan beberapa instrumen yaitu motivasi belajar, motorik (scott motor ability) dan lingkungan sekolah. Data dianalisis mengunakan path analysis. Hasil penelitian menunjukkan 1) terdapat pengaruh langsung dan signifikan motivasi belajar terhadap hasil belajar PJOK pada siswa; 2) terdapat pengaruh langsung kemampuan motorik dan lingkungan terhadap hasil belajar PJOK pada siswa; 3) terdapat pengaruh tidak langsung motivasi belajar dan kemampuan motorik terhadap hasil belajar PJOK melalui lingkungan siswa; 4) terdapat pengaruh yang signifikan antara motivasi belajar, kemampuan motorik dan lingkungan secara simultan terhadap hasil belajar PJOK siswa. Hal ini dapat dimaknai bahwa hasil belajar PJOK siswa dapat ditingkat dengan meningkatkan motivasi belajar dan kemampuan motorik. Selain itu hasil belajar PJOK juga dapat ditingkatkan dengan memaksimalkan lingkungan belajar siswa, baik itu lingkungan fisik maupun lingkungan non-fisik
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
