Separating psychological momentum from strategic momentum: Evidence from men’s professional tennis

In dynamic contests, strategic momentum and psychological momentum potentially coexist, which makes it difficult to distinguish between the two. We employ the setting of professional tennis, which allows us to separate psychological from strategic momentum. In tennis, converting a break point potentially triggers both strategic momentum—due to a change in the relative position of the players—and psychological momentum—due to a change in the perception of the players. To distinguish between these two momentum types, we employ exogenously given interruptions. Interruptions are predicted to affect psychological momentum negatively, while leaving strategic momentum unaffected. Using 4930 game-by-game observations from 141 Grand Slam men’s single matches, we show that the breaking players’ probability of winning a game increases after converting a break point, which provides evidence for momentum. Moreover, we show that this momentum effect is negatively affected by an interruption. Thus, psychological momentum seems to be the main trigger leading to a performance increase after a converted break point.     

运用竞赛教学提高网球课的教学质量

为了探索一种体育教学理论联系实践的新方法,依据竞赛型教学理论,结合网球技术课教学特点,借鉴现代教学理论的成果,针对传统体育教学法的不足,在高校网球课中进行竞赛促进教学实验。结果表明,运用竞赛教学能有效激发学生对网球运动的兴趣,使学生能够积极主动地学习网球基本技术和战术,能够有效提高学生的比赛能力和心理承受能力。     

Parameter Estimation in Large Dynamic Paired Comparison Experiments

Paired comparison data in which the abilities or merits of the objects being compared may be changing over time can be modelled as a non-linear state space model. When the population of objects being compared is large, likelihood-based analyses can be too computationally cumbersome to carry out regularly. This presents a problem for rating populations of chess players and other large groups which often consist of tens of thousands of competitors. This problem is overcome through a computationally simple non-iterative algorithm for fitting a particular dynamic paired comparison model. The algorithm, which improves over the commonly used algorithm of Elo by incorporating the variability in parameter estimates, can be performed regularly even for large populations of competitors. The method is evaluated on simulated data and is applied to ranking the best chess players of all time, and to ranking the top current tennis-players.

论滕尼斯对"共同体"与"社会"的阐释

德国社会学家斐迪南·滕尼斯使用了"共同体"与"社会"的概念对欧洲工业化以来的社会变迁进行诠释,认为共同体是一种自然形成、整体本位的有机体,受本质意志支配,通过默认一致和信仰将人们联系起来;而社会则是非自然形成的、个人本位的机械聚合和人为产物,受选择意志支配,通过法和公众舆论将人们联系起来。滕尼斯提出的"共同体与社会"的类型方法已经形成了社会学当中的一种流派,对后来的社会学理论的发展发生了重要的影响。
