A report of the 1989 NCDA survey of the perceptions of American adults of their career planning, the nature of their workplaces, and the availability of and utility of occupational information is presented. The survey, which was administered by the Gallup Organization, included an oversampling of Hispanics, African Americans, and Asian-Pacific Islanders. Although the results for all groups including Whites are presented, the emphasis is upon the perceptions of minority groups. 相似文献

The design, aims and rationale are outlined of a follow-up study of dropouts from Gamblers Anonymous. A cohort of those attending for the first time and dropping out after more than one meeting was contacted and the cooperators given a structured interview examining factors which may have contributed to decisions to dropout. A comparison group of continuers from the same meeting who had been totally abstinent for at least a year were given the same structured interviews. This first of four parts examines life context factors making it more difficult to maintain attendance, commitment to the treatment program, perceived pre-meeting expectations and reasons for coming, impacts of the first meeting, effects of pressures to maintain attendance and the influence of spouses. 相似文献

Men with and without sexual dysfunction present with varying patterns of agreement between subjective estimates of sexual arousal and more objective psychophysiological measures of the same construct. This relative accuracy seems to be associated with sexual function, with men who have sexual dysfunction presenting less accurate estimations (mostly reporting below measured arousal levels). The purpose of this study is to clarify the processes underlying sexual arousal and the accuracy of its self-estimation. We looked at potential predictors of sexual arousal (subjective and physiological) and accuracy in estimating objective sexual arousal in a sample of 60 sexually functional males. Predictors included pre-existing sexual attitudes (erotophobia), both trait and state positive and negative affect, self-focused attention, and interoceptive awareness. Results indicate that this sexually functional sample generally reported below their own erection level. Interestingly, trait negative affect was associated with somewhat lower levels of subjective arousal and higher levels of physiological arousal. On the other hand, state positive affect facilitated both subjective and objective arousal and increased somewhat the accuracy of estimates of erectile responding. Pre-existing sexual attitudes as well as variations in self-focused attention and interoceptive awareness evidenced little effect on sexual arousal or the accuracy of its estimation. 相似文献

This paper advances the position that sociology needs to develop an approach to research which focuses on fundamental social problems. In doing so it shares many of the intellectual values and goals of political arithmetic while seeking to move methodologically beyond it. Since such problems are complex they will require, typically, interdisciplinary input and a concomitant approach to the development and appraisal of theories. We are not, therefore, advocating the primacy of sociology but arguing that it has a distinctive part to play in addressing the fundamental problems of the twenty-first century. However, a policy-oriented sociology has also to take up the task, so clearly defined by the tradition of political arithmetic, which is to hold governments to account. Consequently a central principle of a new policy science is that it should contribute to democratic debate about policy. 相似文献

The utility of brief interventions with at-risk college drinkers would be enhanced if they could also be delivered in group settings without the need for risk prescreening. The current study therefore explored whether components of brief interventions could be effectively administered to mixed groups of drinking and non-drinking students. Specifically, the outcomes of two methods aimed toward increasing motivation for change were compared to controls. One intervention focused on enhancing actual-ideal drinking behavior discrepancy through a structured group discussion, while the other focused on enhancing self-norm drinking behavior discrepancy through the provision and discussion of didactic information. Among at-risk drinkers, significant reductions in heavy drinking episode frequency at four-week follow-up were found for the self-norm (S-N) group only, while reductions in alcohol problems were obtained in both the S-N and control groups. Results suggest that self-norm discrepancy enhancement strategies may be more effective than actual-ideal discrepancy strategies when used with a mixed drinking group. 相似文献

To address the rise in tobacco use among college students, several national health organizations, including the American College Health Association, recommend that colleges enact smoking bans in and around all campus buildings, including student housing, and prohibit the sale, advertisement, and promotion of tobacco products on campus. Key informants at 50 US public universities, one from each state, were interviewed during the 2001/2002 academic year to assess the prevalence of these recommended policies. More than half (54%) of the colleges banned smoking in all campus buildings and student residences, 68% had no tobacco sales on campus, and 32% of the schools' newspapers did not accept tobacco advertising. Regional differences in adoption of these campus tobacco-control policies were present. Although this national sample of public universities had implemented some of the recommended policies, they must take further actions to comply fully with campus tobacco-control guidelines. 相似文献

Integrins are cell surface receptors that mediate adhesion to the extracellular matrix. In this Perspective, we focus on the recent finding that a decrease in the levels of integrins yields fruit flies that retain youthful mobility as they age and display an increased mean life span. We discuss how the reduction of integrin activity might lead to the observed changes. 相似文献

OBJECTIVE: The primary objectives of this study were to identify sources of meaning for individuals within the context of a work environment, and to compare varied sources of meaning for individuals with high and low work satisfaction levels. METHOD: Participants were chosen based on satisfaction levels in employment, full-time employment status within an organization for at least one year, and diversity in the work setting. Data were gathered through a series of interviews and observations of the participants' workplaces. A comparative analysis of transcribed interviews was conducted by the researchers and with an expert occupational therapy faculty panel. From these analyses, the researchers developed work narratives for a mechanical engineer, a high school teacher, an employee of mechanical services, and a career service counselor. RESULTS: Emerging themes from the work narratives indicated that the various meanings employees found in work had an effect on their perceived levels of job satisfaction. Participants conveyed that organization identification, financial benefits, independent decision-making, reciprocal respect, opportunities for creativity, and maintaining significant relationships outside of work enhanced meaning and satisfaction. CONCLUSIONS: The worker role is a significant source of an individual's identity, meaning, and satisfaction in life. Professionals in various fields can work with employers to develop meaningful work environments for increased job satisfaction, greater motivation for work, increased productivity, and decreased employee turnover. 相似文献
