This paper describes the development and validation of a physical performance test battery to select high pressure cleaning workers at Tennessee Eastman Company. The research uses a concurrent, criterion-related validation strategy to demonstrate the relationship between test performance and job performance. The study proceeded through four stages, with data collected in one stage used in subsequent stages. The two types of predictor measures included ability tests and work sample simulations. For some analyses, the work sample simulations were also used as criteria. Four samples of incumbents (N=63) were tested on all experimental measures. Using criterion groups of successful incumbents and unsuccessful former incumbents (N=33), all of the work simulation tests and the ability-referenced tests were significant predictors of successful versus unsuccessful job status. In addition, the ability tests predicted performance on the work sample simulations, particularly for those requiring strength and endurance. A battery of three ability tests resulted in R=.68 for job status and in R=.43, .73, .80, and .84, respectively, for each of the work sample simulations. Two of the three ability tests in the final test battery are likely to result in adverse impact against females. However, data collected on female maintenance technicians indicated women, as a group, would not be screened out categorically as a result of implementing the physical ability test battery. 相似文献

The sensible response to conflicts of interest is impaired by misconceptions and sloppy usage of terminology. Apparent and potential are widely misused modifiers for conflicts. Excessive legislative focus on financial interests limits understanding of the scope and significance of researchers' conflicts of interest. There is no moral or ethical failing in having a conflict of interest; the problem occurs when conflicts are not disclosed appropriately and when conflicts are allowed to bias research, teaching, or practice. Avoidance and prevention should be applied to bias, not conflicts. 相似文献

Practical issues throughout scientific research can be found to have an ethical aspect. There is a gray area in which scientific error (“honest error”) may be difficult to distinguish from unacceptably poor research practice or an unethical failure to follow scientific norms. Further, there is no clear margin between deceptive practices which are widely accepted and those which must be considered fraudulent. Practical problems arise in matters of data management and presentation, authorship, publication practices, “grantsmanship”, and rights of research trainees, as well as the well-recognized areas of human and animal experimentation. Beyond the gray areas, the legal definition of research misconduct is discussed in relation to research fraud, and the latest proposed definition of the Commission on Research Integrity is briefly reviewed. It is noted that the standards of ethical research are changing. Finally, there is a comment on the idea of institutional integrity in research, and the critical role of the mentor in transmitting research standards to the next generation. 相似文献

Completion responses were collected from younger and older adults for 198 highly constrained sentence contexts that were designed to elicit the same response (i.e., the best completion) in the vast majority of subjects. For each context, completions and their respective frequency of occurrence are provided. Overall, individuals of all ages produced highly similar terminal words. Results of formal analyses indicated that greater socioeconomic status and higher levels of education were mildly associated with a greater probability of producing a best completion response. Although increasing age also correlated with greater probability of producing a best completion, this very weak association would not preclude use of these stimuli with a wide age range. 相似文献

We investigated the separate and combined effects of a behavioral intervention and methylphenidate (Ritalin®) on disruptive behavior and task engagement in 3 children with severe to profound mental retardation. The behavioral intervention involved differential reinforcement of appropriate behavior and guided compliance. All 3 children demonstrated decreased disruptive behavior and improved task engagement in response to the behavioral intervention. Two of the 3 children demonstrated similar improvement in response to methylphenidate. Although both interventions were highly effective for these 2 participants, the relative efficacy of the interventions varied between the 2 children. There was no evidence of an additive or synergistic effect of the two interventions, but the high efficacy of each intervention alone limited our ability to detect such effects. 相似文献

Using a 1-year prospective design, this study examined the influence of family status variables (family income, parental education, family structure), parenting variables (maternal support and restrictive control), peer support, and neighborhood risk on the school performance of 120 African American junior high school students. In addition to main effects of these variables, neighborhood risk was examined as a moderator of the effects of parenting and peer support. Family status variables were not predictive of adolescent school performance as indexed by self-reported grade point average. Maternal support at Time 1 was prospectively related to adolescent grades at Time 2. Neighborhood risk was related to lower grades, while peer support predicted better grades in the prospective analyses. Neighborhood risk also moderated the effects of maternal restrictive control and peer support on adolescent grades in prospective analyses. These findings highlight the importance of an ecological approach to the problem of academic underachievement within the African American community. 相似文献

Two field studies assessed the preconditions and behavioral consequences of relative deprivation. A sample of single mothers receiving government assistance participated in Study 1, and a sample of working women participated in Study 2. We found general support for a 2-factor model of the preconditions of relative deprivation, in which wanting the desired state and deserving the desired state were the best predictors of discontent. In both studies, discontent regarding the status of one's group (i.e., single mothers or working women) was specifically predictive of reports of group-directed protest behaviors. In Study 2, discontent regarding one's own status was specifically predictive of willingness to engage in self-improvement behaviors. Participants in both studies reported more group discontent than personal discontent. These findings provide support from naturalistic settings for the construct of relative deprivation. 相似文献

The ethical issues in conducting research on preventing HIV infection are among the most complex of any area of human subjects
research. This article is an update of a 1987 article that addressed potential conflicts between research design and ethics
with respect to AIDS prevention among injecting drug users. The present article reviews current ethical issues that arise
in the design and conduct of HIV/AIDS prevention research focused on injecting drug users.

This paper identifies social difficulties commonly faced by a group of forty-two Hong Kong transsexuals who had applied for sex reassignment surgery. It describes the use of a systems perspective to conceptualize their problems and a structural family therapy approach to social work intervention. 相似文献
