In light of the present day risk controversies such as global warming and hormones in beef, partially caused by a more globalized world, national differences and similarities in how to manage risks become increasingly important. In this brief "perspective" we focus on how risks are managed in three nations, namely Japan, Sweden, and the United States, specifically focusing on the roles of deliberation, risk analysis, and the importance of cultural factors.  相似文献

This study examined vicarious trauma in clinicians who provide sexual abuse treatment (N = 383). A random sample of clinical members from the Association for the Treatment of Sexual Abusers and American Professional Society on the Abuse of Children were surveyed. Vicarious trauma was measured using the Trauma Stress Institute Belief Scale (Pearlman, 2003). Maltreatment was measured using the Childhood Trauma Questionnaire (Bernstein & Fink, 1998). Respondents reported high rates of childhood maltreatment. Simultaneous multiple regression analyses were used to examine relationships between gender, age, maltreatment history, and vicarious trauma. Male gender predicted greater disrupted cognitions about self-esteem and self-intimacy. Clinician age and childhood emotional neglect predicted greater disrupted cognitions about self-intimacy. Implications for education, practice, and research are discussed.  相似文献

People with mental illness are more likely to experience physical health problems and die prematurely than are comparable populations. This study evaluated whether exercise, when offered as part of routine treatment, affects the psychological and physical health of patients in a high-secure forensic unit in Norway. Thirteen patients completed a structured exercise program lasting 8 to 12 weeks. After completion of the program, resting heart rate and systolic blood pressure after treadmill testing were significantly improved. In addition, patients' subjective feelings of well-being and safety improved significantly. This study shows that structured exercise is possible to perform with noticeable improvements and low attrition among patients with complex conditions. Implications for future studies and practice are discussed.  相似文献

Although there is interest in the role of peers in children's schooling experiences, few researchers have examined associations and related underlying processes between peers’ emotionality, an aspect of temperament, and children's academic achievement. This study evaluated whether target children's (N = 260) own self-regulation, assessed with two behavioral measures, served a moderating function for associations between peers’ emotionality and children's own academic achievement in second grade. There was a positive association between peers’ positive emotionality and reading scores for children with higher self-regulation. Peers’ negative emotionality was negatively related to target children's reading scores, particularly for children with higher self-regulation levels, but was unrelated to math scores. Peers’ positive and negative emotionality did not predict math scores, and there was no strong evidence for the moderating role of target children's self-regulation in this association. This study highlights the potential role of children's self-regulation in modulating peer effects on academic achievement, particularly reading.  相似文献

This article reviews research on the effects of economic recessions on fertility in the developed world. We study how economic downturns, as measured by various indicators, especially by declining GDP levels, falling consumer confidence, and rising unemployment, were found to affect fertility. We also discuss particular mechanisms through which the recession may have influenced fertility behavior, including the effects of economic uncertainty, falling income, changes in the housing market, and rising enrollment in higher education, and also factors that influence fertility indirectly such as declining marriage rates. Most studies find that fertility tends to be pro-cyclical and often rises and declines with the ups and downs of the business cycle. Usually, these aggregate effects are relatively small (typically, a few percentage points) and of short durations; in addition they often influence especially the timing of childbearing and in most cases do not leave an imprint on cohort fertility levels. Therefore, major long-term fertility shifts often continue seemingly uninterrupted during the recession—including the fertility declines before and during the Great Depression of the 1930s and before and during the oil shock crises of the 1970s. Changes in the opportunity costs of childbearing and fertility behavior during economic downturn vary by sex, age, social status, and number of children; childless young adults are usually most affected. Furthermore, various policies and institutions may modify or even reverse the relationship between recessions and fertility. The first evidence pertaining to the recent recession falls in line with these findings. In most countries, the recession has brought a decline in the number of births and fertility rates, often marking a sharp halt to the previous decade of rising fertility rates.  相似文献

This paper shows, through an alternative development of the lot size model, how the methods of capital budgeting can be logically applied to the determination of optimal inventory levels. There is no reason why inventory management needs be treated any differently than the management of fixed assets. The rule that the stock of fixed assets should be expanded until the marginal rate of return equals the marginal cost of capital results from maximizing the present value of profits as a function of the investment level. In a like manner, the “square root” formula from inventory theory results from maximizing the present value of profits as a function of the investment in inventory. In addition, formulating the inventory problem as a capital budgeting problem has advantages for incorporating deterioration, obsolescence, and other costs into the model in a more logical and less intuitive way.  相似文献

Collaborative therapists acknowledge their role in influencing clients and the outcomes of therapy. But the word ‘influence’, for many new to the collaborative therapies, can be mistakenly connoted as an undue exercise of therapist power. From a dialogic and social constructionist perspective, this article reflects on how therapists can be influential in collaborative ways. Negotiating ‘shared intentionalities’ with clients, while privileging their preferences in meaning‐making and change—as part of respecting their primary authorship over their lives—assists therapists to employ their influence in ways that stay collaborative. Furthermore, by regarding client ‘resistance’ and misunderstanding as instructive, therapists can enhance their efforts to stay collaborative.  相似文献
