The authors investigated vigorous physical activity, psychological well-being, and self-reported illness during transition to first-year university life in a sample of 175 Canadian undergraduates. At the completion of their first year of university study, participants completed retrospective measures assessing vigorous physical activity, upper respiratory infectious illness (URI), doctor visits, as well as measures of psychological well-being. Based on nationally recommended (US Department of Health and Human Services) standards, 61% of students reported engaging in adequate levels of vigorous activity during their first year at university. The authors found no differences in URIs between sufficiently and insufficiently active students. However, insufficiently active students scored lower on psychological well-being and were twice as likely to have consulted a physician regarding an illness compared with sufficiently active students. 相似文献

Concerns have been raised regarding the appropriateness of asking about violence victimization in telephone interviews and whether asking such questions increases respondents' distress or risk for harm. However, no large-scale studies have evaluated the impact of asking such questions during a telephone interview. This study explored respondents' reactions to questions regarding violence in two large recently completed telephone surveys. After respondents were asked about violence, they were asked if they thought surveys should ask such questions and whether they felt upset or afraid because of the questions. In both surveys, the majority of respondents (regardless of their victimization history) were willing to answer questions about violence and were not upset or afraid because of the questions. More than 92% of respondents thought such questions should be asked. These results challenge commonly held beliefs and assumptions and provide some assurance to those concerned with the ethical collection of data on violent victimization. 相似文献

An unrestricted sociosexual orientation (the endorsement of casual sex) has been found to correlate with undesirable behaviors and personality characteristics more so in men than in women. Using a community sample of men and women, we investigated the correlations between sociosexuality and behaviors, motives, attitudes, and fantasies related to sexual aggression. Participants (n = 168; ages 21-45) completed self-report measures of sociosexual orientation, sexual conservatism, rape myth acceptance, adversarial sexual beliefs, attitudes toward women, sexual behaviors, and perpetration of sexual aggression. Participants also wrote five brief stories that were scored for power and affiliation-intimacy motives and two sexual fantasies that were coded for the theme of dominance. For both men and women, an unrestricted sociosexual orientation was correlated with behavioral items indicating earlier life experiences with sex, a greater number of lifetime sex partners, and more frequent sexual activity. For men, an unrestricted sociosexual orientation was linked with higher levels of rape myth acceptance and adversarial sexual beliefs; more conservative attitudes toward women; higher levels of power motivation and lower levels of affiliation-intimacy motivation; and past use of sexual aggression. For women, an unrestricted sociosexual orientation was associated with sexual fantasies of dominance and lower levels of sexual conservatism. 相似文献

Life style research has become an independent branch of social structure analysis, that systematically complements classical research on social inequality in the explanation of social action and of attitudes. However, there are important theoretical gaps in life style research: firstly, there is a lack of theoretical proposals to explain the statistical connection between life styles on the one hand and social action and attitudes on the other hand. Secondly, it remains unclear, why life styles sometimes are very good predictors of social action and at other times they are not. In a first step this article puts forward an action theoretic framework as foundation for life style research, that implies a conceptual shift from life styles to cultural preferences. In a second step I develop three theses, that state relatively precisely the conditions for a high or low explanatory power of cultural preferences. They are empirically tested in a secondary data analysis, that supports the applicability of the theoretical ideas developed in the paper. 相似文献

This paper discusses the opposition of civil society to nonferrous metals mining in Montana. The mineral resources and mining history of Montana are discussed, as is the vibrant civil society of that state. Montana’s civil society has opposed mining due to its environmental effects, particularly upon areas of high conservation value. This opposition has involved litigation and the implementation of a ban on the use of cyanide by the mining industry. The paper concludes with a discussion of whether this opposition to mining has damaged the economy of the state and Montana’s future as an example of the “New West,” wherein amenities based growth act as the principal agent of economic activity. 相似文献

In response to a growing diversity of opinion regarding educational models and essential content in clinical social work education,
this paper offers a perspective concerning graduate clinical curricula. Part I, the foundational piece of the paper, discusses
the definition of clinical social work, social work’s core orientation and values, and influential contextual issues. The
interrelated core orientations guiding knowledge and skill development are identified as the person-in-situation perspective and the concept of relationship. Based on this foundation, Part II identifies elements of a contemporary biopsychosocial knowledge base and essential clinical
skills. This paper is intended to stimulate dialogue about a topic of importance to the profession and the clients it serves. 相似文献

If an anonymous rule f always outputs a transitive relation and satisfies Pareto, then, by Arrow’s theorem, f violates the condition of independence. We give lower and upper bounds for the number of times an anonymous rule violates
independence in the case of three alternatives and three voters. 相似文献

Assessment of individuals' psychological well-being and mental health is an important aspect of health promotion. The purpose of this study was to examine the relationship between perception of psychological well-being and general health report among Jordanian university students. A total of 1108 students from six universities in Jordan were surveyed regarding psychological well-being and general health. The results showed that students perceived their psychological well-being as moderate. Psychological wellbeing subscales were negatively correlated with reports of physical pain, chronic infections, and previous or current treatment of a psychiatric illness. Male and female university students were similar in their perceptions of psychological well-being; however, they differed in their general health report. Perception of psychological well-being is an important component of university students' health. The importance of psychological well-being is highlighted, and implications for mental health nurses are presented. 相似文献

Serious mental illness places a tremendous burden on clients, their families, and behavioral and medical health care providers. The co-occurrence of diabetes with mental illness may further compromise daily functioning. Psychiatric nurses can make a significant difference in improving the health and medical outcomes of this client population. A partnership was developed between the University of Rochester School of Nursing and the Western New York Care Coordination Program to evaluate a novel nursing model for adults with both serious mental illness and diabetes mellitus. The Well Balanced program incorporated health promotion, disease management, nursing care management, and evidence-based practice guidelines into 8 Steps to Wellness for a community-based mental health population. During a 16-visit intervention period, psychiatric nurses interacted with 74 clients. As a result of the program, clients experienced improvements in health risk status and in their hemoglobin A1C and reported high satisfaction with the Well Balanced program. 相似文献

There has been no research linking implementation of a public smoking ban and reduced incidence of acute myocardial infarction (AMI) among nonsmoking patients. An ex post facto matched control group study was conducted to determine whether there was a change in hospital admissions for AMI among nonsmoking patients after a public smoking ban was implemented in Monroe County compared with Delaware County, Indiana without such a ban. Poisson analysis was conducted for 44 months of hospital admissions. A significant drop occurred in the number of admissions among nonsmoking patients in Monroe County after the ban whereas a nonsignificant decrease in the number of admissions occurred in Delaware County. The changes in the number of smoking-patient admissions before and after the ban were not significant. 相似文献
