The impact of participation in sports on educational attainment—New evidence from Germany     

Christian Pfeifer  Thomas Cornelißen 《Economics of Education Review》2010,29(1):94-103

We analyze the impact of exercising sports during childhood and adolescence on educational attainment. The theoretical framework is based on models of allocation of time and educational productivity. Using the rich information from the German Socio-Economic Panel (GSOEP), we apply generalized ordered probit models to estimate the effect of participation in sport activities on secondary school degrees and professional degrees. Even after controlling for important variables and selection into sport, we find strong evidence that the effect of sport on educational attainment is statistically significant and positive.  相似文献   

USING FOCUS GROUPS AS AN EDUCATIONAL METHODOLOGY: DECONSTRUCTING STEREOTYPES AND SOCIAL WORK PRACTICE MISCONCEPTIONS CONCERNING AGING AND OLDER ADULTS     

Harriet L. Cohen  Mark H. Sandel  Cecilia L. Thomas  Thomas R. Barton 《Educational gerontology》2013,39(4):329-346

During the coming years the number of older adults will increase dramatically, which will require a corresponding increase in the number of social workers who have accurate knowledge of this population. This article reports the impact focus groups with older adults and with service providers who work with older adults and their families have on baccalaureate social work (BSW) students. We find that BSW students exposed to focus groups have their negative attitudes about older adults and service providers deconstructed and replaced with more positive and accurate information about older adults. When students' misconceptions about older adults are confronted, they become more interested in choosing geriatric social work as a career option.  相似文献

Extinction and retraining of simultaneous and successive flavor conditioning     

Higgins T  Rescorla RA 《Learning & behavior》2004,32(2):213-219

In three experiments, rats received pairings of flavor conditioned stimuli with polycose unconditioned stimuli, in either a simultaneous or a sequential relation. Both temporal relations produced excellent conditioned increases in consumption of the flavors. Separate presentation of the flavors resulted in extinction in both cases. However, restoring the pairing of the flavor with polycose resulted in reconditioning only with the sequential, not with the simultaneous, relation.  相似文献   

The influence of moment of inertia on baseball/softball bat swing speed   总被引：1，自引：1，他引：0

The speed at which a player can swing a bat is central to the games of baseball and softball, determining, to a large extent, the hit speed of the ball. Experimental and analytical studies of bat swing speed were conducted with particular emphasis on the influence of bat moment of inertia on swing speed. Two distinct sets of experiments measured the swing speed of colege baseball and fast-pitch softball players using weighted rods and modified bats. The swing targets included flexible targets, balls on a tee and machine pitched balls. Internal mass alterations provided a range of inertial properties. The average measured speeds, from 22 to 31 m s⁻¹, are consistent with previous studies. Bat speed approximately correlates with the moment of inertia of the bat about a vertical axis of rotation through the batter's body, the speed generally decreasing as this moment of inertia increases. The analytical model assumes pure rotation of the batter/bat system about a vertical axis through the batter's body. Aerodynamic drag of the batter's arms and the bat is included in the model. The independent variable is bat moment of inertia about the rotation axis. There is reasonable agreement between the model and the measured speeds. Detailed differences between the two suggest the importance of additional degrees of freedom in determining swing speed.  相似文献
