The effects of self-determination vs. teacher-determination of timeout duration on disruptive behavior were investigated in a group of 15 students in a special classroom who had learning disabilities and/or behavior problems. There were five phases to the study: In a repeated measures design each subject received timeout for 5 minutes, no timeout, 5 minutes timeout, selfdetermined timeout duration, and student = teacher-determined timeout duration. The overall effect of timeout was to reduce significantly the rate of disruptive behavior. The effects of various timeout conditions did not differ, indicating self-management of timeout duration was just as effective as when the teacher set the timeout duration. 相似文献

Federal legislation requires that research produced with federal funding be available to the public under the Freedom of Information Act. I raise a concern that this power might be used to harass scientists. The goal of data sharing, however, is important, and should be facilitated through electronic data archiving. 相似文献

The purpose of this study was to develop a portable force measurement system for ice hockey skating. The system consisted
of three strain gauge pairs affixed to an ice hockey skate’s blade holder with wire leads connected to a microprocessor controlled
data acquisition device carried in a backpack worn by the skater. The configuration of the strain gauges simultaneously determined
the vertical and medial–lateral force components experienced by the blade holder with a resolution accuracy of 1.9 N and a
coefficient of variation of 9.2%. On-ice testing of this system with subjects performing forward start, acceleration, and
constant velocity skating permitted unencumbered, natural movement and demonstrated clear, unambiguous signal responses, high
trial-to-trial repeatability, and easy data retrieval. The practicality and accuracy of this testing approach have many applications,
such as a quantitative tool for skating force assessment to aid athletes and coaches, as well as providing the means to examine
other skill-specific dynamics. 相似文献
