Substituting basketball players during competition is a key process to optimise collective performance. Available research on this topic is scarce, probably due to the difficulty in isolating these effects; thus, the aim of this study was to identify the temporal effects of substitutions in basketball (Spanish professional basketball league). The sample was composed of 1118 substitutions gathered from 21 basketball games. The analysed variables were coach-controlled (player and team’s personal fouls, player in and player out roles, player’s in and out minutes on-court and timeout situation); on-court (foul committed, free throws, 2- and 3-point field-goal effectiveness) and situational variables (scoreline, quality of opposition, game location and game quarter). The results showed positive scoring performances after the substitution for all the analyses. During the first quarter, there were significant effects for fouls committed, scoreline and game location after the substitution. The player’s out personal fouls, free-throw effectiveness, player in, minutes on-court player in, timeout situation and 3-point field-goal effectiveness were significant during the second quarter. The team’s personal fouls, game location, and scoreline were identified as important in the third quarter. The fourth quarter did not show significant effects on the independent variables. Current findings allow optimising coaches’ plans and team management of on-court and bench players throughout the game.  相似文献   

Swedish PE teachers’ understandings of legitimate movement in a criterion-referenced grading system     

Lena Svennberg 《Physical Education & Sport Pedagogy》2017,22(3):257-269

Background: Physical Education (PE) has been associated with a multi-activity model in which movement is related to sport discourses and sport techniques. However, as in many international contexts, the Swedish national PE syllabus calls for a wider and more inclusive concept of movement. Complex movement adapted to different settings is valued, and in the national grading criteria qualitative measures of movement are used. This research seeks to examine how the wider concept of movement is interpreted and graded. Drawing on Bernstein’s concept of the pedagogic device, the paper explores teachers’ roles as active mediators in the transformation of national grading criteria for movement and the kinds of movement that are valued in teachers’ grading practices. Purpose: The purpose of this study is to investigate what PE teachers consider legitimate movement in a criterion-referenced grading system and the factors that influence their grading practice. The Repertory Grid (RG) technique was employed in order to access their tacit knowledge. Methodology: Seven Swedish PE teachers were interviewed, all of whom teach and grade years seven to nine in different compulsory schools. Using the RG technique, the teachers were asked to reflect on the aspects they considered important for achieving a high grade. The national grading criteria for years seven to nine were then presented one at a time and the teachers were asked to describe how they assessed and graded each requirement. The teachers were also asked whether any specific factors had influenced their grading. In the content analysis, the second part of the interview was attended to first and the results were interpreted in light of Bernsteins’ concept of the pedagogic device. Findings: Sport techniques and competitive sports influenced the teachers’ interpretations of what constitutes complex movement. The aspect of fitness also appeared to be valued by the teachers in that it facilitates the valued movement. In some cases the difficulty of describing movement qualities in words could reduce the concept of movement to something measurable and quantifiable. The teachers’ concerns about students’ unequal opportunities to develop and demonstrate their skills also influenced the teachers’ interpretation of complex movement. Conclusions: In the transformation of national grading criteria to grading practice, the pedagogic actions taken inform and limit the way in which legitimate movement in PE is conceptualised. Adopting a concept of movement that is wider than competitive sports allows the structures of inequality to be addressed and enables the movements performed by students with other moving experiences than competitive sports to be valued. The tension between the demands of transparency in a high stakes grading system and the inability to articulate the quality of complex movements is problematic. There is a need to verbalise teachers’ conceptions about physical education knowledge to be able to discuss and develop the concept of movement. In this process, the RG technique is a potentially useful tool. Having the language to discuss movement qualities also enables us to strengthen the interrelation between curriculum, pedagogy and assessment.  相似文献   

Wartime imaginings of an archipelagic community: Fajar Asia and the quest for peninsula Malayan and Indonesian unity     

Sandra Khor Manickam 《Inter-Asia Cultural Studies》2017,18(3):347-363

During a brief period in the Japanese occupation of Southeast Asia, Malaya, including Singapore, was administratively placed with Sumatra under Japan’s 25th Army. From 28 March 1942 to April 1943, the two territories that had been separated by British and Dutch colonial rule since the mid-nineteenth century were considered one territory. This article explores how Malay intellectuals, through articles written in the magazine Fajar Asia, took advantage of this unprecedented opportunity to strive for a Malaya-Sumatra and Malaya-Indonesia community. This article will analyse the various wartime imaginings of a joint archipelagic community within the pages of Fajar Asia and highlight tensions within this project which resulted in an impasse as to how such a unity should or could be achieved.  相似文献

How to respond to journalists’ questions? A new perspective on Chinese premiers’ aggressiveness at press conferences (1993–2015)     

Feng Wu  Hong Zhao 《亚洲交流杂志》2016,26(5):446-465

This study extends the framework describing journalists’ aggressiveness at politicians’ press conference and develops five dimensions to measure politicians’ aggressiveness in response to journalists’ questions (initiative, directness, assertiveness, adversarialness, and accountability). Using the records from Chinese premiers’ press conferences (1993–2015), this research investigates five factors which might affect premiers’ aggressiveness: the administrative life cycle, economic conditions, journalists’ country of origin, the topic of questions, and number of questions. The results show that premiers exhibit less assertiveness during honeymoon periods and more assertiveness in other years. Premiers are more adversarial amid good economic growth but less adversarial during poor economic growth. They are more assertive and adversarial in response to questions related to politics and the military and less so in response to questions related to other areas. Premiers display more initiative and accountability toward journalists who ask more questions and less toward those who ask fewer questions. Premiers are more assertive and adversarial toward journalists from developed countries but less so toward those from developing countries. Over the past 23 years, premiers’ initiative, directness, and adversarialness have decreased while their accountability has gradually increased. The theoretical contributions of this research are discussed.  相似文献   

中外女排比赛接拦回球效果及失误原因的比较分析     

李华燕 《湖北体育科技》2016,(11):1001-1004

中外女排比赛中接拦回球数量仍然较多,占扣球总数的14%左右,比赛中80%左右的拦回球落在3m线前区域。中国女排接拦回球的效果好于日本女排、塞尔维亚女排和多米尼加女排,但与巴西女排、美国女排相比差距较大,同俄罗斯女排、意大利女排接拦回球的效果相差不大。接拦回球失误的主要原因有接拦回球队员反应跟不上造成无防守动作形成失误,其次是接拦回球队员防守意识不强未及时进入防守位置形成失误。中国女排应加强接拦回球跟进保护意识培养,努力提高各种倒地和单手垫球技术,从而提高接拦回球能力。  相似文献   

第17届排球世锦赛中外女排进攻效果对比研究     

潘文刚  杨管 《辽宁体育科技》2016,(1):95-98

运用录像观察、数理统计和对比分析等方法,对中外女排在第17届世锦赛中扣球技战术运用情况进行研究。结果表明：中国女排是以两边拉开进攻为主并结合高度与速度等快变战术为一体的技战术打法;进攻战术的总体运用效果十分理想,与其他各国相比扣死率较高且失误率低;后排攻在比赛中展现出了强大的实力,但在强攻和快攻方面与巴西、美国等欧美强队相比还存在一定差距。建议中国女排应进一步加强对强攻能力的训练,尤其要努力丰富年轻队员的大赛阅历以保证其技术发挥的稳定性;在面对欧美强队时应努力提高一传到位率,并加强进攻队员之间的掩护配合,使各种快变战术能够在比赛中得到有效发挥,并尽量避免自身进攻方式及手段的单一化。  相似文献
