The Impact of Coach Leadership Style on Resilience of Volleyball Players
Full text linkThe purpose of this study was to investigate the impact of coach leadership style on resilience level of volleyball players and to trace possible differences that exist between the two genders. Participants included 101 volleyball players (53 females and 48 males) and 31 coaches (11 females and 20 males), with the Self Evaluation Resilience test and the Leadership Scale for Sport (LSS) used as instruments. The data was analyzed with SPSS 21.0 using t-test for independent samples, and simple regression (stepwise) analysis. Results of t-test showed statistically significant differences between male and female volleyball players in ‘‘orientation on solution and aims’’ and ‘‘self-efficacy’’ variables, with no other statistically significant differences observed for the rest resilience variables. Additionally, no statistically significant differences were observed for the LSS variables between the two genders of volleyball coaches. The results of simple regression (stepwise) analysis suggest that the autocratic behavior of volleyball coach has a significant impact on volleyball players’ resilience. Future research should investigate whether variables such as anxiety affect the resilience level of volleyball players
Categorias de equipes e diferenças de gênero na resiliência entre jogadores de voleibol seniores
No full textIntroduction. The objective of this study was to investigate he difference in resilience level of high-level volleyball players of different team categories. Methods. Ninety-eight volleyball players (50 males and 48 females) of the national team U21, Pre-League and Second Division A2 teams participated in the study and their perceptions were examined using the Self Evaluation Resilience test. Statistical analysis included the use of SPSS 21.0 including t-test for independent samples, and one-way ANOVA with post hoc Bonferroni adjustment test. Results showed statistically significant differences between male and female volleyball players in ‘‘orientation on solution and aims’’’ and ‘‘self-efficacy’’ variables and between players of different team categories concerning ‘‘orientation on solution and aims’’, ‘‘healthy lifestyle’’ and ‘‘self-efficacy’’. Future research should investigate whether coaching behavior affects the resilience level of the players in different categories.Introducción. El objetivo de este estudio era investigar la diferencia entre el nivel de resiliencia de los jugadores de voleibol de alto nivel y entre categorías de equipos. Método. En el estudio participaron 98 jugadores de voleibol (jugadores de la selección nacional U21, jugadores de los equipos de Pre-Liga y Segunda División A2) (cincuenta mujeres y cuarenta y ocho hombres). Para el estudio se utilizó la prueba de autoevaluación de resiliencia. Los datos fueron analizados con SPSS 21.0 utilizando la prueba t para muestras independientes y ANOVA de una vía (de sentido único) con la prueba de ajuste de Bonferroni post hoc. Los resultados mostraron diferencias estadísticamente significativas entre los jugadores de voleibol masculinos y femeninos en las variables "orientación hacia la solución y los objetivos" y "autoeficacia". Además, se observaron diferencias estadísticamente significativas en las variables "orientación en la solución y objetivos", "estilo de vida saludable" y "autoeficacia" de acuerdo con la categoría del equipo de jugadores. Las búsquedas futuras deberían investigar si el comportamiento del entrenador en el equipo, o la categoría del equipo, afectan al nivel de resiliencia de los jugadores.Introdução. O objetivo deste estudo foi investigar a diferença entre o nível de resiliência de jogadores de voleibol de alto nível e entre categorias de times. Método. O estudo incluiu 98 jogadores de voleibol (jogadores da seleção nacional Sub-21, jogadores das equipes da Pré-Liga e da Segunda Divisão A2) (cinquenta mulheres e quarenta e oito homens). O teste de autoavaliação de resiliência foi utilizado para o estudo. Os dados foram analisados ??com SPSS 21.0 usando o teste t para amostras independentes e ANOVA one-way (one-way) com o teste de ajuste post hoc de Bonferroni. Os resultados mostraram diferenças estatisticamente significativas entre os jogadores de voleibol masculino e feminino nas variáveis ??"orientação para solução e objetivos" e "autoeficácia". Além disso, foram observadas diferenças estatisticamente significativas nas variáveis ??"orientação na solução e objetivos", "estilo de vida saudável" e "autoeficácia" de acordo com a categoria do time de jogadores. Pesquisas futuras devem investigar se o comportamento do treinador na equipe, ou a categoria da equipe, afeta o nível de resiliência dos jogadores
Assessing Resilience in Youth (U16) Volleyball National Teams
Full text linkThe objective of this study was to investigate the resilience of youth high level volleyball players. Forty-eight volleyball national team players U16 from Greece and Romania participated to the study (18 females and 30 males). The Self Evaluation Resilience test was used for the study. The data were analyzed with SPSS 21.0 using one-way ANOVA with post hoc Bonferroni adjustment test. Results showed statistically significant differences between the males and females national team volleyball players in variables ‘‘healthy lifestyle’’ and ‘‘self-efficacy’’. It was concluded that coaches and volleyball players should recognize that female’s volleyball players focused more in healthy life style and having less self-efficacy comparing to same aged male’s volleyball players
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
