We describe a general-purpose, programmable system that provides high-quality, low-cost devices for experimentation in psychoacoustics and speech perception. The system is controlled by a host computer (e.g., an IBM PC), over a serial line. Through the use of a high-level, general-purpose experiment control program, the designed interconnection of devices can be specified logically, and the settings of the devices modified dynamically, during the experiment. 相似文献

The two major purposes of the present study were (1) to empirically investigate the effects of excessive pressures perceived by Ph.D.-level scientists and engineers employed in a large multidivisional energy R&D laboratory on work attitudes and performance; and (2) to test the proposition that scientists with managerial responsibilities perceive more pressures and strains than do those with no such duties. Results indicated that the pressured scientists perceived more role strain and a less positive climate, were less satisfied, and received lower performance evaluations from their supervisors than non-pressured ones. No differences were found in the perception of pressures between the managerial and nonmanagerial scientists, although the managers reported a more positive climate and higher satisfaction than did nonmanagers. The implications of these findings with regard to management practice (i.e., dual ladders) and future research on stress among this occupational group were briefly discussed. 相似文献

The Preconceptional Family Health Evaluation Program was a regional project developed and funded for 2 years by the New England Regional Genetics Group (NERGG) to educate family planning health professionals about genetics, and to offer family planning clients preconceptional identification of genetic and environmental exposure risks. To meet these goals, genetic education was provided on a regional basis to 45 family planning professionals. A self-administered family health risk questionnaire adaptable to individual family planning settings was developed. Five hundred and twenty-nine family planning clients voluntarily completed the questionnaire. Cigarette smoking (35%) and alcohol use (57%) were two major categories of risks identified. The Preconceptional Family Health Evaluation Program was well received by all participants and provided an effective means for regional education of family planning health professionals. As a result of the program, state program planners, clinical genetics services, and family planning health professionals developed a strong relationship that will serve future educational and genetic risk screening efforts. 相似文献

This investigation was conducted in an effort to systematically extend the emerging data base having to do with choice-making opportunities and the behavior of students with disabilities. In particular, the current analyses examined the effects of choice-making on the problem behavior and task engagement of three high school students with intellectual disabilities as the students performed domestic and vocational activities. Multiple baseline and reversal designs demonstrated that the choice conditions reduced problem behaviors and increased task engagement for all participants. Data having to do with student affect and task productivity were less consistent. The findings on the relationship between choice making and problem behavior replicate and extend a growing literature on the desirable effects of choice-making for individuals with disabilities. The results are discussed in terms of recent developments in behavioral support, as well as the need for ongoing conceptual and applied research. 相似文献

Conclusion The values articulated in the system of care philosophy (Stroul & Friedman, 1994) have been necessary elements of local, state, and national efforts to reform mental health care for children. The importance of the values of family collaboration, cultural competence, interagency coordination, individualized care, and use of the least restrictive treatment setting articulated by the system of care philosophy has been affirmed by practitioners, policy makers, and mental health services researchers. Such values, however, are likely not sufficient to achieve clinical outcome. Clinical outcomes are more likely to be achieved by family members and therapists when clinical practices are changed to reflect the demanding and comprehensive work of changing child and family social ecologies. 相似文献
