对新规则下直拍进攻型打法发展趋势的研究     

赵霞  苏丕仁  张浩 《北京体育大学学报》2006,29(1):122-124

直拍进攻型打法曾经是我国乒坛的主流打法,由于缺乏创新,在近10多年一直不太景气.但是,直拍进攻型打法有其特定的优势,具有很强的抗争能力,只要创新技术、加强实力,就能登上世界乒坛的最高峰;诚然,它自身的确也存在着很多问题,加上11分赛制和无遮挡发球的实行,必定会给这种打法带来一些影响(正负双方面).因此,在新形势下对直拍进攻型打法进行进一步的深入剖析和探讨,成为我国乒坛亟待解决的课题.通过对世界优秀男子直拍进攻型打法选手的技战术进行统计与分析,并走访乒乓界权威人士和有关专家,对新规则带来的一些问题和该打法今后的发展趋势进行深入分析与探讨,为进一步提高我国直拍进攻型打法的技术水平提供科学理论和参考依据.  相似文献

陈绍文  张庆建 《辽宁体育科技》2005,27(2):75-76

国际乒联在2001年把沿用了近百年的每局比赛21分制改为每局11分制。这一规则变动将对乒乓球运动产生巨大的影响，同时也对运动员的多方面能力提出了新的要求。本文就乒乓球11分记分制和21分记分制进行了对比分析，探讨了11分新赛制的特点及适应对策。  相似文献   

2002世界杯足球决赛中国队守门员位置防守技术运用分析     

张强  张力  董向荣  张立平 《四川体育科学》2003,(4):43-45

主要运用观察和统计归纳的方法，对中国队参加第17届世界杯足球赛决赛阶段比赛的守门员位置防守技术运用情况进行分析。结果表明，判断选位与反应能力的不足，导致中国队守门员防射门技术运用失误增多，防守的成功率降低；比赛中中国队守门员把握出击的能力低，出击欠灵巧机变，强对抗条件下难以有效发挥位置防守优势，守门员技术稳定是心理稳定的体现，训练实践中既要加强守门员意识引导，更要加强守门员意志的培养，努力改变比赛中守门员技术不过硬的现状。  相似文献

How should cultural diversity be measured? An application using the French publishing industry     

Françoise Benhamou  Stéphanie Peltier 《Journal of Cultural Economics》2007,31(2):85-107

Despite the lack of a clear definition of the concept, “cultural diversity” has remained a core issue for more than a decade (WTO, UNESCO, etc.). The aim of this paper is to begin to fill this gap. We argue that cultural diversity is a multi-dimensional concept and that accurate metrics must rely on three criteria: variety, balance and disparity. We also stress that supplied and consumed diversity have to be distinguished. We apply this set of multiple measures of diversity to publishing data for France over the period 1990–2003. Our main result is that the situation of the publishing industry in terms of cultural diversity is highly dependent on the dimension considered. Hence, diversity increases when variety is the sole consideration, whereas taking balance or disparity into account leads to the opposite conclusion. This issue raises a series of questions about the use of diversity measures in a policy debate concerned with furthering cultural diversity.

Long-Term Sociopolitical Effects of 9/11 Television Viewing,Emotions, and Parental Conversation in U.S. Young Adults Who Were Children in 2001     

J. Brian Houston 《Communication Research Reports》2013,30(3):183-192

This research used a survey to examine how 9/11 television viewing, emotions, and parental conversation influenced current sociopolitical attitudes of young adults who were children in 2001. Young adults who watched more television coverage of the 9/11 attacks as children were found to exhibit lower levels of social trust and support for immigration now, whereas young adults who had more frequent conversations about 9/11 with their parents as children were found to have more confidence in U.S. political institutions and to exhibit more support for immigration. These results illustrate that, although the psychological distress from an event like 9/11 may fade for children not directly affected by the event, the influence of that event on how young people think about the world may remain, and that media coverage of and parental conversation about the event play significant roles in influencing these long-term effects.  相似文献   

Writing culture; inscribing lives: a reflective treatise on the burden of representation in native research     

Ameena Ghaffar-Kucher 《International journal of qualitative studies in education》2013,26(10):1186-1202

This paper complicates the contested assumptions surrounding native research by exploring the burden of representation placed on native researchers because they are seen as insiders. This particular issue of representation is important for native researchers to consider, especially in instances where the research is on an understudied or politically charged group, because of the ways in which the socio-political climate influences both the telling and the reading of such research. Drawing on the author’s personal struggles as a Pakistani researcher conducting ethnographic research with Pakistani immigrants in the United States in the post-9/11 climate, this paper explores and critiques the role of the native researcher and the issues involved with representing understudied groups. Specifically, the paper focuses on authenticity, positionality, audience, and accountability. Thus, the paper is a call for researchers to be more reflective and to think more deeply about their positionality and its impact on the various constituents as they research and write. To encourage such reflexivity, the article provides a set of questions for researchers to consider at different stages of the research and writing process.  相似文献
