TEACHING METHODS OF PRACTICE STYLE AND COMMAND STYLE IN IMPROVING THE SKILL OF BUTTERFLY STROKE
Get PDFThe objective of this research is to find out different impacts of the teaching methods; practice style and command style. This research is conducted in the Faculty of Sports Science, State University of Padang during the academic year of 2010/2011. The applied research method is an experimental method. The sample consists of 40 (college) students who are divided into 4 groups of 10 persons. The data analysis technique is performed by a two-ways variance analysis followed by the tukey test at the significance level = 0, 05. The results of this research are: 1) in all aspects, the skill of butterfly stroke by the teaching method of command style is better than the practice style, 2) for the students with high motor skills, the skill of butterfly stroke by the teaching method of practice style is better than the command style, and 3) for the students with low motor skills, the skill of butterfly stroke by the teaching method of command style is better than the practice style. Keywords: teaching methods of practice style and command style; motoric abilities; the skill of butterfly stroke

Pengembangan Aplikasi Self Assessment Dalam Pembelajaran Bola Basket
Get PDFThe problem in this study is the lack of youth athletes representing POPDA in Kab. Kampar due to the difficulty of teachers assessing youth athletes to take part in regional championships, especially basketball. The aim is to determine the validity of developing a web-based self-assessment application and to determine the reliability of the developed self-assessment application. This type of research is RnD using the ADDIE model. The subjects in this study were students of SMKN 1 Bangkinang Kota, taking samples by random sampling and the number of samples was 32 students. The data collection instrument used expert validation questionnaires, documentation, and basketball shooting tests. The data analysis technique used was the Aiken rater score analysis. The results of this study were that filling out a questionnaire by basketball experts obtained a value of 1,000 with a very valid category, measurement test experts obtained a value of 0.840 with a high category, material curriculum experts obtained a value of 0.932 in a high category and evaluation expert obtained a value of 0.932 in a high category with a reliability test result of 0.868 with reliable category. From the trial, it was found that 24 out of 32 students had succeeded in reaching the school KKM limit of 75. It can be concluded that the basketball shooting self-assessment application is valid and reliable and can be used as an assessment medium used by PJOK teachers in assessing students
Comparison of Serum HIF-1α Levels in Swimming Athletes Before and After Hypoxic Non-Hypoxic Exercise
Get PDFThe situation of lack of oxygen supply to cells and tissues is often not realized by many people (hypoxia). Hypoxia can occur in various situations in life. The main effect of hypoxia is the effect on the brain, so the body will do everything it can to restore the state of homeostasis. HIF-1α protein is a marker of hypoxic conditions. HIF-1α regulates the synthesis of many genes to maintain and restore body homeostasis from hypoxia to normoxia. This study was a descriptive study with cross-sectional design. The sample of this study were six swimming athletes with a 12-19 year age range who met the inclusion and exclusion criteria. The HIF-1α protein is measured by the ELISA method. Data were analyzed statistically. The results showed higher levels of HIF-1α after anaerobic exercise than the levels of HIF-1α before and after aerobic exercise. This is greatly influenced by the intensity of the exercise carried out. This proves that cellular adaptation to hypoxia is more stable in aerobic exercise, where the body's metabolism during aerobic exercise is more stable  
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
