新规则导向下世界女子竞技体操格局及发展趋势的研究

运用文献资料法、数理统计法和专家访谈法，结合新规则对39届世界体操锦标赛女子团体、全能和单项前8名运动员的比赛成绩、动作难度和完成情况进行了比较分析。结果表明：世界女子体操的格局基本稳定；全能比赛呈现出强项突出，单项均衡发展的特点；单项比赛的竞争呈现出个性化、特长化的发展趋势，技术的发展要求在动作难度和编排上不断创新，同时注重表现的艺术性和发挥的稳定性。     

从第13、14届世界健美操锦标赛成绩看竞技健美操竞争格局与发展态势

采用文献资料法、录像观察法和比较分析法对第13、14届世界健美操锦标赛成绩进行对比分析,并结合2013-2016年周期新规则,探究世界竞技健美操竞争格局和发展态势,为中国竞技健美操进一步发展提供可借鉴的理论依据。研究认为:竞赛规则指引着竞技健美操发展方向,对新规则的理解和掌握直接影响着比赛成绩;世界竞技健美操保持欧亚大陆雌雄争夺、美洲势单力薄的"偏"三足鼎立竞争格局;亚洲国家总奖牌数和金银铜牌数追平乃至超越欧洲国家,强烈冲击欧洲国家长久统治的主宰地位;中国竞技健美操在经历低谷后焕发崭新生机,重新进入国际领军集团;世界竞技健美操呈现国际化发展的确定性和洲际、国家强弱流动的不确定性互相交织的态势发展。     

规则修改对中级别散打运动员进攻组合技术运用的影响

运用文献资料、观摩等研究方法,对分别在散打规则修改前后进行的2003年与2004年两次全国锦标赛中中级别运动员运用的组合技术进行了统计,分析探讨规则修改后对中级别运动员组合技术运用的影响。结果发现:从总体来看,规则修改有效地增进了中级别散打比赛的激烈程度,提高了观赏的价值,基本达到了修改规则的目的;规则修改后,中级别散打运动员运用2击组合技术中,平均每局运用次数除BB类和AB类有所下降之外,其他各类组合的运用频率均呈上升趋势;3击组合中,除BC类运用次数有显著性上升之外,其他各类变化均不明显;4击及4击以上组合则基本变化不大。     

Batting last as a home advantage factor in men's NCAA tournament baseball

In baseball and softball, there is a rule that allows the home team to have the last at-bat and thus the final opportunity to win the game. However, in tournament play, this rule is often set aside and, instead, batting order is decided by other means (e.g. tournament rules, the flip of a coin). The purpose of this study was to examine the impact of the batting last rule on game outcome in NCAA men's regional tournament baseball. It was hypothesized that host (i.e. home) teams would win a greater percentage of the games in which they batted last compared with when they batted first. This hypothesis was not supported. Closer examination of the last inning of play showed home teams were no more likely to have won the game during their last bat than visitors playing other visitors. The results suggest that the batting last rule contributes minimally, if at all, to home advantage in NCAA tournament baseball.

Judges’ delivery of ground rules to child witnesses in Australian courts

Ground rules directions are given to children in forensic interviews to explain what is expected of them, and to reduce their tendency to acquiesce to erroneous or incomprehensible questions. Ground rules may also be necessary when children provide testimony in court. Drawing on research conducted for the Australian Royal Commission into Institutional Responses to Child Sexual Abuse, the present study examined the use of ground rules directions delivered in court in 52 trials by 24 presiding judges in three jurisdictions to 57 child complainants (aged 7–17.5 years). Eleven categories of rules were identified. The number of words spoken to deliver each rule was counted, and grade-level readability scores were calculated as a proxy for the complexity of the ground rules. When judges asked comprehension or practice questions, the question types were coded. More than one third of the children (35%) received no ground rules directions from the judge; the remaining 65% received directions on an average of 3.5 types of ground rules out of a maximum of 11 types. While comprehension questions were common, practice questions were rare. Comprehension questions were most often presented in a yes/no format that implied the expected response, although this form of question is unlikely to provide an effective assessment of a child's comprehension. Neither the number of rules delivered nor the number of words used was related to children's age. Implications for children's court testimony are discussed.
