The effect of perceived streakiness on the shot-taking behaviour of basketball players

Abstract

We examine behavioural changes of basketball players arising from the hot-hand belief and use data of 1216 National Basketball Association games to measure the effect of cold and hot streaks on three proxies of shot difficulty. We find that the more consecutive shots players make (miss), the more difficult (easier) shots become along the three dimensions. Furthermore, most players' performance seems to improve during hot streaks because they attempt more difficult shots while no significant decrease in shooting accuracy takes place. This might explain why most previous studies could not find empirical evidence for the hot-hand belief in basketball when considering in-game field goal shooting.     

国内影子银行的发展与监管

我国金融体系的改革与创新伴随着金融脱媒,传统银行功能减弱而直接融资渠道功能增强,国内影子银行逐渐兴起。我国影子银行体系以银行为绝对主导,从事常规银行信贷以外的信用发放活动。但是,我国影子银行体系资金来源并不稳定,而资金运用投向不够透明,通过对影子银行体系资产端和渠道中介的监管,可以预防由此引发的金融风险。     

Physical structure of winter sports athletes

A review of the results concerning the body size, growth, maturation, shape, composition, and strength of ice hockey players, cross‐country skiers, alpine skiers, ski jumpers and Nordic combined skiers is presented. The comparisons of the results in body height, weight, somatotypes, percent fat, LBM and hand grip from various authors are made. Also the differences between ice hockey players and skiers of all disciplines are shown. The review covers all the available results. It may be concluded that the elite athletes in each studied sport form a highly select group which has, from the biomechanical point of view, the best physical structure for their sport discipline.

凝固过程中生长界面前沿质点的排斥过程研究

For in-situ composite materials, the interaction between the second-phase particles and the solidification interface attracts more attentions of people, for concerning the final distribution of the particles on the matrix. With the conception of the local solidification time, a kinematics mechanism of particle pushing into the crystal boundary during the solidification process was assumed.Through the analysis of forces acted on the particle in front of the solid/liquid interface the critical velocity criterion for the particles pushing was given. The calculation results show when the growth rate of the interface V is less than or equals to the critical velocity Vc. the particles on the solid/liquid interface is pushed into the boundary region of cellular crystals, where they are distributed as a chain-like straight, which forms a particle-strengthened in-situ composite materials.
