ABSTRACTThe literature on momentum is still undecided, with mixed results whether momentum exists or is only perceived to exist (“hot hand fallacy”). We explore whether momentum exists by looking at cases in which a basketball player has three consecutive free throws. A free throw is a well-defined task executed in a stable environment, allegedly giving momentum optimal chances to occur. Taking 14 NBA seasons we collected over 4500 three-free-throw sets (triplets). We obtained the outcomes of the shots as well as some additional variables about the player and the game: the player’s average free-throw percentage, home or away, and the game score and the quarter when the free throws were attempted. We first analyse the hit rates in the three shots and then proceed to regression analysis that also controls for the abovementioned variables. We address several concerns raised in the literature. All comparisons and analyses yield the same conclusion that there is no evidence for momentum in the data. 相似文献

Neural engineering is an emerging field of high relevance to students, teachers, and the general public. This Feature presents online resources that educators and scientists can use to introduce students to neural engineering and to integrate core ideas from the life sciences, physical sciences, social sciences, computer science, and engineering into the classroom. 相似文献

This article deals with the first years of foundation of the private Deutsche Hochschule für Leibesübungen (DHfL). It focuses on the question of why August Bier’s application for a Doktor der Leibesübungen in 1920 was refused. In the same year the DHfL also made an application for the education in state-run schools which was already task of the state-run Preußische Landesturnanstalt at Spandau. As the DHfL combined this application with its insistence on its autonomous status an application for a Doktor der Leibesübungen had implied financial, conceptual and institutional obligations for Prussia and at the same time a renuncitation of its sovereign rights. This thesis was proved by a comparison between the doctorate in physical education and the doctorate for businessmen at Cologne University. 相似文献
