Creating a Web-accessible,point-of-care,team-based information system (PoinTIS): the librarian as publisher     

Suzetta C. Burrows  Kelly M. Moore  Henry L. Lemkau  Jr. 《Journal of the Medical Library Association》2001,89(2):154-164

The Internet has created new opportunities for librarians to develop information systems that are readily accessible at the point of care. This paper describes the multiyear process used to justify, fund, design, develop, promote, and evaluate a rehabilitation prototype of a point-of-care, team-based information system (PoinTIS) and train health care providers to use this prototype for their spinal cord injury and traumatic brain injury patient care and education activities. PoinTIS is a successful model for librarians in the twenty-first century to serve as publishers of information created or used by their parent organizations and to respond to the opportunities for information dissemination provided by recent technological advances.  相似文献   

Examining the specificity of practice hypothesis: is learning modality specific?     

J Coull  L Tremblay  D Elliott 《Research quarterly for exercise and sport》2001,72(4):345-354

The specificity of practice hypothesis was examined using a tracking task. In Experiment 1, visual or auditory feedback about performance was provided. Vision was more useful than audition early in acquisition. Performance gains found in acquisition were maintained during retention, but learning was specific only if the acquisition modality was visual. Specificity did not increase with the amount of practice. In Experiment 2, visual and auditory information were combined. Again, the specificity of practice hypothesis was supported. Also, instructing participants to attend to one information source allowed us to demonstrate that information can be explicitly or implicitly processed. Further, specificity effects may occur because of different rates of development for error detection and correction processes.  相似文献

Not an outgroup, not yet an ingroup: Immigrants in the Stereotype Content Model   总被引：4，自引：1，他引：3  

Tiane L. Lee  Susan T. Fiske 《Int J Intercult Relat》2006,30(6):751

Stereotype research depicts the generic immigrant as incompetent and untrustworthy. The current research expands this image, specifying key information dimensions (e.g. nationality, socioeconomic status) about immigrants. To see how perceivers differentiate among particular immigrant groups, we extend a model of intergroup perception, the Stereotype Content Model (SCM; Fiske, Cuddy, Glick, & Xu, 2002. Journal of Personality and Social Psychology, 82, 878–902), to immigrant subgroups. The SCM predicts that perception centers on competence and warmth, and relates to targets’ perceived status and competition within society. Specified by nationality, race, ethnicity, and class, images of immigrants differ by both competence and warmth, with most groups receiving ambivalent (low–high or high–low) stereotypes rather than the uniform low–low for the generic immigrant. As predicted, ambivalent stereotypes reflect target nationality combined with socioeconomic status, supporting the SCM's ambivalent stereotypes and social structural hypotheses, as well as better defining immigrant stereotypes and their contingencies.  相似文献

一、前言 目前大多数用优化方法设计一个复现轨迹的机构,主要是考虑运动性能,通过运动分析,建立起关于指定点与给定点的位置误差的目标函数,而本文试图通过力分析,设计一个四杆机构,使指定点能复现预期轨迹,从而把运动学问题与动力学问题结合起来,为同时满足运动性能和动力性能,设计出更为合理的机构提供了一种可行的方法。  相似文献

A static method for obtaining a calibration factor for SRM bicycle power cranks   总被引：1，自引：0，他引：1  

Andrea L. Wooles  Anthony J. Robinson  Peter S. Keen 《Sports Engineering》2005,8(3):137-144

Many scientists and coaches are interested in mechanical power produced during cycling, and use Schoberer Rad Me\technik (SRM) bicycle power cranks to obtain this data. However, it has been expensive and difficult to calibrate SRM cranks, causing much of the collected data to be unreliable. We present a static method, derived from first principles, for obtaining a calibration factor for SRM cranks. A known mass and lever arm (chainring of a known diameter) are used to apply a known torque load to the instrument in four positions, and the output frequencies are used to calculate the calibration factor in Hz/Nm. The reproducibility of this method is ±0.01 Hz/Nm, which is acceptable for the application of the instrument, which is measurement of mechanical power application by cyclists at the crank. The method is reliable, inexpensive, and easy to set up, and will allow higher confidence in data collected using SRM power cranks. We recommend calibration of the power meter once every six months because of the measured drift of the calibration factor over time.  相似文献
