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   

CERN document server: Document management system for grey literature in a networked environment     

Martin?VeselyEmail author  Thomas?Baron  Jean-Yves?Le?Meur  Tibor?Simko 《Publishing Research Quarterly》2004,20(1):77-83

Conclusion In this paper we briefly described the current status of research in the field of digital libraries interoperability, mainly with respect to federated data processing such as permitted within the Open Archive Initiative framework. We then presented the CERN Document Server Software suite that is a free software package main-tained by CERN providing an online digital library solution for mid- to large-sized document repositories. The set of CDSware modules was described and the differ-ences with other existing tools briefly mentioned. Finally we have mentioned a typical usage statistics illustrating the scope of grey literature and networked con-ditions of the CERN Document Server. We pointed out that the current trend in grey literature management goes toward institutional repositories build upon the distributed and federated model. Further research is going on within the CDS collaboration in this area, focused particularly on (i) semantic interoperability using ontologies in distributed and federated data processing and (ii) ranking technologies when searching grey literature in OAI compliant repositories.  相似文献   

Ethnic and regional influences on teachers' evaluations of oral answers     

Thomas K Crowl  Joanne R Nurss 《Contemporary educational psychology》1976,1(3):236-240

Tape recordings were made of six white and six black ninth-grade northern boys speaking identically worded answers to typical school questions. Black students were given significantly higher grades than white students by 56 white and 50 black southern teachers. Black teachers gave significantly higher grades than white teachers, but no significant interaction was found between students' and teachers' ethnic group. The study is a partial replication of a previous study in which it was found that black students were given significantly lower grades than white students by northern white teachers.  相似文献
