VBSPT Application of basketball measurement for adolescent
No full textVan Basketball Skill and Performance Test (VBSPT) is designed to assist basketball athletes and basketball coaches in assessing their performance based on the test results and adhering to the training guidelines derived from the application's recommendations. The development goal of the VBSPT is to directly view their performance statistics based on the test results, which will benefit not only basketball coaches but also physical education teachers. These apps are designed to operate on smartphones and tablets; the adaptive applied software undergoes continuous enhancements and serves as the central component of the computer. The two elements (15 items) of the web-based application of the van basketball skill and performance test (VBSPT) were evaluated by a group of 10 experts. The study involved the participation of five experts in information technology and five basketball coach experts. The Delphi approach and test-retest methods were employed for data collection, while Aiken's formula, intraclass correlation coefficients (ICC), and Cronbach's alpha were utilized for data analysis. The expert assessment technique indicates that the content validity of the aspect is good, as evidenced by the results with a value of 0.80. The reliability of each feature of the basketball skill and performance test instrument was assessed using Cronbach's alpha, yielding a coefficient of 0.723. The ICC score agreement between raters is 0.723, with a consistency of 0.148 for one rater. Based on the results, the reliability and usability standards were met. VBSPT is a valuable tool for checking a web-based application's technical quality and usability.Van Basketball Skill and Performance Test (VBSPT) está diseñado para ayudar a los deportistas y entrenadores de baloncesto a evaluar su rendimiento basándose en los resultados del test y siguiendo las pautas de entrenamiento derivadas de las recomendaciones de la aplicación.

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
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
