Abstract

The aim of this study was to determine potential relationships between anthropometric parameters and athletic performance with special consideration to repeated-sprint ability (RSA). Sixteen players of the senior male Qatar national soccer team performed a series of anthropometric and physical tests including countermovement jumps without (CMJ) and with free arms (CMJwA), straight-line 20 m sprint, RSA (6 × 35 m with 10 s recovery) and incremental field test. Significant (P < 0.05) relationships occurred between muscle-to-bone ratio and both CMJs height (r ranging from 0.56 to 0.69) as well as with all RSA-related variables (r < –0.53 for sprinting times and r = 0.54 for maximal sprinting speed) with the exception of the sprint decrement score (S_dec). The sum of six skinfolds and adipose mass index were largely correlated with S_dec (r = 0.68, P < 0.01 and r = 0.55, P < 0.05, respectively) but not with total time (TT, r = 0.44 and 0.33, P > 0.05, respectively) or any standard athletic tests. Multiple regression analyses indicated that muscular cross-sectional area for mid-thigh, adipose index, straight-line 20 m time, maximal sprinting speed and CMJwA are the strongest predictors of S_dec (r² = 0.89) and TT (r² = 0.95) during our RSA test. In the Qatar national soccer team, players’ power-related qualities and RSA are associated with a high muscular profile and a low adiposity. This supports the relevance of explosive power for the soccer players and the larger importance of neuromuscular qualities determining the RSA.  相似文献

Abstract

This study analyzes Japanese and Korean ethno-national (minzoku-kokumin) education in postwar Japan. During a period of political unrest in Japan (1945–1955), some of the Korean residents and Japanese worked together to overcome the culture of Imperial Japan and its assimilative education. They also regarded themselves as people colonized by the United States, and pursued a political-cultural movement for their liberation and independence from American imperialism. The Koreans in Japan rejected compulsory education in the Japanese language. As a result, since 1956, Korean schools (Chōsengakkō), funded and supported by North Korea, were founded all across Japan. Their ethno-national education was in fact incorporated into North Korean politics, and has been considered in many studies as having overcome Japanese assimilation and ethnic inequalities. Such a view was a result of many academic Zainichi Korean studies that come from an “insider's perspective” to criticize Japanese colonialism and discrimination. In order to go beyond this insider's view, I focus on the political alliance between Zainichi Koreans and the Japanese people in their pursuit of ethno-national education. Since 2010, the Japanese state funding for Korean schools has become a major controversy in Japan. By tracing the historical background, this article intends to explain why this political issue has arisen. The ultimate purpose of this article is to suggest an ethical perspective to resolve the current political conflict regarding Korean schools in Japan.  相似文献   

A Time of Transition     

《Journal of Teaching in Social Work》2013,33(1-2):211-219

Abstract

This narrative describes, from a personal perspective, the aging and dying processes of a social worker's parents, and the impact that this process had on her teaching in the area of social work practice and gerontology. The impact of a personal crisis on one's professional role is dramatic. Issues related to social support, the conflict inherent in multiple roles, and the burdens and joys of caretaking are explored in an effort to offer readers the opportunity to understand the complexities of the aging process. Furthermore, the dilemmas inherent in teaching about a topic that has such important and personal implications for teachers and learners are examined.  相似文献

Studying parental involvement and university access and choice: An ‘interacting multiple capitals’ model          下载免费PDF全文

Fang Gao  Jacky Chi Kit Ng 《British Educational Research Journal》2017,43(6):1206-1224

Capital‐embedded parental involvement in education is essential in enhancing university enrolment and maximising the educational potentials for equality and excellence. Previous studies in this field have mainly utilised Perna's ( 2000 , 2006 ) model, which defines parental involvement as social capital and identifies the additive influences of different types of capital (including social, economic and cultural capital) on university access and choice. Yet, little research to date theorises and disaggregates the interplay among various types of capital as well as the multiplicative capital effects on enrolment. This study addressed this gap. We proposed an ‘interacting multiple capitals’ (IMC) model and hypothesised that parental social capital could moderate the effects of cultural and economic capital on entry to university. To validate the model, a pilot survey was administered to 216 university students of Korean ethnicity in China and investigated the models of involvement adopted by Korean parents in the context of the increasing labour mobility of the Korean adult population. Moderated multiple regression analysis was employed and the results confirmed the hypothesis that capital effects upon university access and choice were multiplicative in nature, with social capital moderating the cultural capital influence on students’ educational aspirations. The study findings show that the interaction of various types of capital variables is sufficiently statistically significant to warrant future research and policy and practical discussion of how to promote parental involvement in university preparation and planning.  相似文献

Agenda setting in multilateral contexts: the example of the Decade of Education for Sustainable Development     

Sugata Sumida 《Globalisation, Societies & Education》2017,15(4):381-396

A number of papers have focused on UN policy formulation processes, but little is known about how particular issues come to policy-makers’ attention in the first place. This very early stage of policy formulation, called agenda setting, remains under-researched and more so in multilateral contexts. Applying Kingdon’s multiple streams model to the example of the Decade of Education for Sustainable Development (DESD), this study analyses the trajectory of the policy from being just an idea to the point of being placed on the UN agenda. This paper goes on to argue that there are three conditions that supported the successful trajectory of DESD: a funding-backed policy entrepreneur, policy oligopoly, and a highly predictable policy window. Its theoretical contribution is to fill the gap between current studies and theories by presenting an analysis of one policy in a multilateral context.  相似文献
