This study surveyed 975 undergraduates attending a large East Coast university during the spring semester of the 1987/88 academic year. A convenience sample of predominantly black students (94%) participated. Overall, knowledge of basic AIDS-related facts was satisfactory. Raw scores on the 25-item knowledge scale ranged from 7 to 25, with a mean of 20.5 (82%) and a mode of 22 (88%). Selected questions on how HIV is not transmitted, however, posed some problems for respondents. Less than 30% of respondents knew that the AIDs virus was not transmitted by insects; less than 80% knew that AIDS was not transmitted on toilet seats, through blood donations, kissing, and coughing. The survey also asked students whether they had ever engaged in certain behaviors that put them at risk of HIV infection. Approximately 17% of respondents had experienced anal intercourse, 6.5% reported use of heroin, 32.6% reported having had multiple sex partners, and 16% had been treated for a sexually transmitted disease. Students who reported engaging in high-risk behaviors had statistically significant lower mean knowledge scores than those who reported not engaging in those same high-risk behaviors. Results of the study support the need to increase efforts to deliver AIDS information specifically targeted to individuals who may be engaged in high-risk behaviors. Special health education programs must be designed to focus attention on risk behaviors (ie, unprotected anal intercourse) instead of risk groups (ie, homosexual and bisexual males).  相似文献

This paper examines perceptions of money within marriage, focusing upon the concepts of control and ownership. It considers the criteria involved in Pahl's (1983; 1989) typology for the allocation of income, and their ability to capture the dynamic perceptual elements associated with change. These issues were explored by means of data from semi-structured interviews, using mainly middle-class couples (thirteen women and nine of their partners) in the 30–50 year age-range. Most of the women were in the process of returning to the labour market following an absence of at least eight years. The findings demonstrate, on the one hand, that Pahl's revised typology (1989), which includes an emphasis on the person possessing overall control, can be used to trace major shifts in the balance of economic power as a function of the life-cycle and associated changes in the source of income. On the other hand, the findings also show that a couple's report of their financial arrangements, concerning the Spooling’ of income, can yield the erroneous impression that resources are equally shared. In particular, the ‘rights’ of ownership associated with having earned the income may remain hidden, and lead to patterns of overall control with potential consequences for a non-earning, dependent partner.  相似文献

New technology is calling on people to provide adaptive responses in situations where there are many exceptions or where a high degree of variability exists or where people provide linkages between programmable segments. Further, groups of people who are geographically dispersed and unacquainted with each other will work together to solve business problems or define a process and will then disband when the job is done. Thus, the general model of responsible autonomous job behavior becomes the key facet of individual-organization-technological relationships. It is suggested that this model is best activated by the empowerment of people through the value-based management of transformational leadership.  相似文献

Responses of 33 gay fathers were compared with those of 33 heterosexual fathers on the Value of Children scale, an empirical measure of the reasons for wanting to become a parent. Responses of gay fathers did not differ significantly from heterosexual fathers on the majority of the items of the inventory, but differences were found on two subscales, Tradition-Continuity-Security and Social Status. Item analysis of responses shows that gay fathers may have particularly significant reasons motivating them to become parents.  相似文献

Summary Stress has been a focus of attention for several years amongvarious professional groups, including social work. However,only limited attention has been given to stress experiencedby academics and even less to social work lecturers. This paperexamines job satisfaction, felt pressure and stress amongstsocial work lecturers in the United Kingdom. It looks at demands,supports and constraints, psychological well-being, the impactof the department and the institution, and changes that mightalleviate stress. The results obtained are compared, where possible,with studies of social workers and, in particular, academicsin general. A 60-item postal questionnaire was sent to all social work lecturersin the United Kingdom; 322 responses were received. Respondentsenjoyed undertaking a wide variety of tasks and apparently receivedvarying amounts of support from their managers. The social worklecturers experienced high levels of job satisfaction and stressscores were similar to those of the general United Kingdom population.But a significant proportion - one quarter - of social worklecturers were suffering from borderline levels of anxiety anddepression. Overall, social work lecturers' responses were morefavourable than the responses of other academics and socialworkers. In common with other research on stress, this studysuggests that pressure and stress should not be seen primarilyas individual problems, but as a product of interactions atteam, department and institutional levels, and at the home/workinterface.  相似文献

Summary.  We examine the claim that the well-known Petersen estimator which is used in population size estimation was not in fact used by the scientist after whom it is named. We show how, in the early years of the last century, the modern use of the Petersen estimator grew from that of the fishing coefficient. Contending with the somewhat conflicting claims that were made at the time, and what by modern standards is poor referencing of sources, we investigate where the credit lies for these concepts, and the principles and protocols which support them. We assess also how far attributions of credit were affected by practical considerations, and the history of the estimator by the nature of the problems being pursued. We identify scientists whose early work on marking and estimating fish populations deserves more credit than it has received.  相似文献
