2013年世界女排大奖赛总决赛中国队与巴西队技战术运用分析

2013年世界女排大奖赛总决赛中、巴之战是2008年以来,中国女排第13次落败于巴西队,为什么总是遇巴而败,为什么一传到位率在举国体制下的中国仍旧成为战败的主要问题;为什么面对欧美高大进攻队员仍旧势单力薄,单人拦网率居高不下;为什么丰富全面的战术预案下,调整球永远是公诸于众的四号位强攻,通过比赛录像的分析统计,运用文献资料法、数理统计法、对比分析等方法,探秘中、巴怪圈,欲透过表象探析问题的本质,从根本上寻求切实有效的方式方法。作者认为,不论是差距的寻找,还是问题的解决,都需要从事物的根本性质进行分析,需要对主体内因进行剖析。排球运动的项目属性及根本特征才是决定战术打法、训练理念及比赛宗旨的根本,而主体的培养体制、训练环境,以及认知理念才是比赛结果的主要原因。

Trajectories of maternal verbal aggression across the middle school years: associations with negative view of self and social problems

Objective

The primary research objective was to explore the relationship between trajectories of maternal verbal aggression (VA) experienced by low-income, community middle school students across a three-year period and outcomes that have been found to be related to VA in previous work, including a negative view of self and social problems.

Method

Longitudinal data were collected from 421 youth (51.8% male) attending two middle schools over 3 years using a multiple-informant survey design. K-means cluster analysis was used to identify trajectories of VA using youth ratings of the Conflict Tactics Scale: Parent-Child (Straus, Hamby, Finkelhor, Moore, & Runyan, 1998). Dependent variables were self-reported depression, self-esteem, delinquency, and peer victimization as well as peer-rated aggression and sensitive-isolated reputation.

Results

Four trajectory groups of VA were identified: Low Stable, Increasing, Decreasing, and High Stable. The 3-year average occurrence of VA was: 1.31, 9.18, 10.24, and 31.14 instances, respectively. Gender-specific MANOVAs revealed dramatic differences between the High Stable and Low Stable groups. High Stable boys reported significantly more depressive symptoms, delinquency, peer overt and relational victimization, and were less likely to have a sensitive/isolated reputation than Low Stable boys. High Stable girls reported significantly more depressive symptoms, low self-esteem, delinquency, peer overt and relational victimization and were rated by peers as having more aggressive/disruptive and relationally aggressive reputations than Low Stable girls. Girls in the High Stable group were more likely than other youth to report levels of depressive symptoms and delinquency >1 SD above the mean, while boys in the High Stable group were more likely to report levels of delinquency >1 SD above the mean. The Increasing and Decreasing groups also demonstrated significantly poorer functioning than the Low Stable group on most outcomes. Growth curve analysis revealed that VA showed a contemporaneous association with self-reported delinquency suggesting these factors are closely related.

Conclusions

Any level of VA greater than the 1–2 instances per year reported by youth in the Low Stable group was associated with less favorable outcomes.

2011年羽毛球世锦赛男单决赛技战术特征探究

通过反复观察林丹和李宗伟在2011年羽毛球世锦赛男单决赛中的表现,对两位选手的发球与接发球技术、攻防相持能力、主动得失分使用技术、关键分技术运用等全场各项技术指标进行统计和分析。研究结果表明:林丹处理网前球以挑球为主,李宗伟以搓放网前球为主。杀球成为两人得分的主动技术手段,林丹的杀球能力明显高于李宗伟。两位选手在发球和接发球得分相差不大,林丹相持能力略优于李宗伟;关键球处理上,林丹的技战术水平明显高对手。林丹凭借着略胜一筹的相持能力和关键球处理的优势,最终实现逆转取得比赛的胜利。
