我国男篮优秀后卫攻防能力分析与评价

以2003-2004年CBA12支队34名后卫为研究对象,采用比较研究、聚类分析等方法,得出我国后卫平均年龄25 4岁,身高主要集中180-190cm之间;后位与中锋、前锋相比扣篮、盖帽、得分能力和篮板球较差,抢断、助攻方面较强;我国优秀后卫在得分、总篮板、被侵与外援有显著差异;按聚类分析结果,我国后卫攻防能力可分5个层次。     

第12届欧洲杯足球赛进攻战术运用的探讨

通过对第12届欧洲杯足球赛各相关技术数据进行统计分析,并对比第11届欧洲杯足球赛及第17届世界杯足球赛的有关资料统计,探讨现代足球比赛中进攻战术运用的基本特征。结果表明:本届杯赛以整体攻防、快速攻防为主要特征,进攻的效率决定比赛的胜负;边路进攻、定位球战术突显威力,特别是角球战术倍受重视,反映了未来足球进攻战术发展的趋势。     

第13届世界女篮锦标赛大前锋进攻的特点

通过对1998年5～6月在德国举行的第13届世界女篮锦标赛部分大前锋进攻特点的研究，从中揭示出本届世界女篮大前锋进攻特点，探究女篮大前锋进攻技术、比赛运用诸方面的发展趋向，为我国女篮大前锋的选材、训练与使用提供理论与实践依据。     

2007年女足世界杯中国队与巴西队进攻战术打法的比较研究

通过文献资料、录像观察和数理统计法,对第5届FIFA女足世界杯赛中国与巴西两支球队进攻战术统计数据进行比较与分析。结果表明,中国队整体的进攻能力低于巴西队,包括比赛进球时间、进球队员位置和进攻有效手段。针对中国女足与巴西女足的实际表现,揭示中、巴两国足球队的共性特征及差异,为改善中国女足的进攻战术打法提供参考。     

Author ranking evaluation at scale

We evaluate author impact indicators and ranking algorithms on two publication databases using large test data sets of well-established researchers. The test data consists of (1) ACM fellowship and (2) various life-time achievement awards. We also evaluate different approaches of dividing credit of papers among co-authors and analyse the impact of self-citations. Furthermore, we evaluate different graph normalisation approaches for when PageRank is computed on author citation graphs.We find that PageRank outperforms citation counts in identifying well-established researchers. This holds true when PageRank is computed on author citation graphs but also when PageRank is computed on paper graphs and paper scores are divided among co-authors. In general, the best results are obtained when co-authors receive an equal share of a paper's score, independent of which impact indicator is used to compute paper scores. The results also show that removing author self-citations improves the results of most ranking metrics. Lastly, we find that it is more important to personalise the PageRank algorithm appropriately on the paper level than deciding whether to include or exclude self-citations. However, on the author level, we find that author graph normalisation is more important than personalisation.     

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.     

第31届奥运会男篮参赛球队攻防能力研究

采用文献资料法、录像观察法和秩和比法等,对参加31届奥运会男篮比赛球队的攻防能力进行综合量化评价,并将中国男篮与对手的攻防能力指标进行对比分析.结果显示:中国男篮进攻RSR处于D级,在得分、助攻、3分球命中率与罚球命中率上,与对手存在非常显著性差异,在失误数、进攻篮板、3分球出手数上与对手存在显著性差异;中国男篮防守RSR处于D级,防守篮板数比对手少,而失分和犯规数比对手多,且在犯规数上与法国男篮存在显著性差异;中国男篮攻防RSR处于E级;球队最终排名与进攻RSR值和攻防RSR值之间存在非常显著性相关.     

美国篮球经典进攻战术体系形成的必然性研究

摘要：以4个美国经典进攻战术体系为研究案例，通过文献资料法、专家访谈法及实地考察法对美国经典进攻战术体系形成的必然性进行了剖析，以期对我国篮球教练员构建进攻战术体系提供参考。研究认为竞争基因是美国篮球运动发源和发展的基础，发达的社会经济和巨大的资金投入、激烈频繁的赛事、高等教育及多元化哲学思想的影响、Scouting技术和篮球规则的改变等因素的综合作用使美国篮球进攻战术体系的形成成为必然。我国应借鉴美国大学篮球的成功因素，从而推动我国大学篮球运动的快速发展。
