The concepts of informed consent and surveillance of human research designed to protect human subjects is commendable. The regulations of the Institutional Review Board (IRB) are having a major impact on clinical cancer research. There is greater administrative time needed of the investigator, the mechanisms of patient care have become cumbersome and some patients reject optional medical management that could be life saving. IRB regulations must be flexible to meet the needs of human subjects as well as those of the clinical investigator.  相似文献

We discuss how using vocational interests in the selection process can help address the diversity-validity dilemma. First, we point out how incorporating vocational interests as predictors in selection could help to reduce adverse impact. We further suggest that by using optimal predictor weights, one could simultaneously improve validity while enhancing organisational diversity. Finally, the predictive validity of vocational interests arises from their ability to capture the congruence between individuals and occupations, which is a cross-level phenomenon. Thus, when gathering validity evidence for vocational interests, multi-occupation samples should be incorporated into validation efforts.  相似文献

Following adaptation, only the trained limb misreaches to the remembered location of targets. This suggests a change in the feit position of the trained limb, but conflicts with recent reports, and with the hypothesis that when a limb changes, the remembered location of targets encountered only by that limb undergo some change too. It suggests that information is stored independently of the mode of acquisition.  相似文献

We studied the academic effects on peers without disabilities of serving as peer supports for students with disabilities in general education classrooms. Three peers were studied using a range of indicators, including academic engagement, coursework performance, and social validity assessments. Peers assisting a student with disabilities via curricular adaptation, assignment completion, and social facilitation constituted the multicomponent independent variable. We used withdrawal or multiple baseline designs to demonstrate positive benefits for peers for all measures used. In addition, follow-up data for 2 peers indicated that the positive changes associated with serving as a peer support were maintained for up to 2 months. Our results are discussed in relation to the possible academic and social effects of providing peer supports in general education classrooms for students with and without disabilities.  相似文献
