Rural dwelling elders who experience mental health problems often have difficulty finding help since rural communities often lack adequate mental health service providers. This paper reports on the initial phase of a 5-year, interdisciplinary clinical research study that is testing the effectiveness of providing a home delivered, therapeutic psychosocial intervention, aimed at improving the emotional wellbeing and the quality of life of medically frail elders who live in rural communities. In the early phases of this study, the clinical research team encountered a number of interesting and often unanticipated challenges as it attempted to recruit study participants and provide services to them. In this article, we examine these challenges and share what we have learned so far about providing mental health services to elderly persons living in rural environments.  相似文献

A number of investigators have explored the use of value of information (VOI) analysis to evaluate alternative information collection procedures in diverse decision-making contexts. This paper presents an analytic framework for determining the value of toxicity information used in risk-based decision making. The framework is specifically designed to explore the trade-offs between cost, timeliness, and uncertainty reduction associated with different toxicity-testing methodologies. The use of the proposed framework is demonstrated by two illustrative applications which, although based on simplified assumptions, show the insights that can be obtained through the use of VOI analysis. Specifically, these results suggest that timeliness of information collection has a significant impact on estimates of the VOI of chemical toxicity tests, even in the presence of smaller reductions in uncertainty. The framework introduces the concept of the expected value of delayed sample information, as an extension to the usual expected value of sample information, to accommodate the reductions in value resulting from delayed decision making. Our analysis also suggests that lower cost and higher throughput testing also may be beneficial in terms of public health benefits by increasing the number of substances that can be evaluated within a given budget. When the relative value is expressed in terms of return-on-investment per testing strategy, the differences can be substantial.  相似文献

This review of the governance practices of twenty-five public-private partnerships involved in addressing a broad range of community health needs shows that governance in public-private community partnerships departs significantly from traditional notions of institutional governance. Governance structures and degrees of progress toward governance goals vary widely and appear to be systematically related to the organization, composition, location, and activity of each partnership.  相似文献

In this article I explore an often overlooked feature of everyday life that can serve as a powerful heuristic for students to engage history and geograhpy critically: everyday place-names. Drawing on scholarship in critical toponymy, I explore how the city-text—the past as it is overlaid on top of the geography of the community through place-names—serves to commemorate particular histories that are often simultaneously exclusionary and taken-for-granted. Outlining three of the city-text's primary features—its unconventional narrative structure that emphasizes a worldview, its existence as a manifestation of state control over commemoration in the community, and its exclusive focus on heroism—I suggest that social studies classrooms be sites from which students critically engage the everyday city-texts of their own communities as a way of fostering critical thinking skills and commitments to historical and geographic critique.  相似文献

Predicting catastrophes involves heavy‐tailed distributions with no mean, eluding proactive policy as expected cost‐benefit analysis fails. We study US government counterterrorism policy, given heightened risk of terrorism. But terrorism also involves human behavior. We synthesize the behavioral and statistical aspects in an adversary‐defender game. Calibration to extensive data shows that where a Weibull distribution is the best predictor, US counterterrorism policy is rational (and optimal). Here, we estimate the adversary's unobserved variables, e.g., difficulty of an attack. We also find cases where the best predictor is a Generalized‐Pareto with no finite mean and rational policy fails. Here, we offer “work‐arounds”. (JEL H56, D81, C46)  相似文献

Cultural studies professed ‘radical contextualism’ imbues the project with a particular orientation toward ‘the present,’ a consideration of ‘the current moment’ as a configuration of forces shaping possibilities for politically engaged practice and affording concrete potentials for telling better stories. This essay elaborates these claims by way of tribute to Lawrence Grossberg. It is neither retrospective nor prospective. Instead – and in a manner more befitting a figure who continues to champion the political-intellectual practice of cultural studies here and now, in the present – this essay reflects on the author’s experiences learning with and from Grossberg in order to explore the the temporality of the cultural studies project.  相似文献

This paper proposes a new method for identifying social interactions using conditional variance restrictions. The method provides a consistent estimate of the social multiplier when social interactions take the “linear‐in‐means” form (Manski (1993)). When social interactions are not of the linear‐in‐means form, the estimator, under certain conditions, continues to form the basis of a consistent test of the no social interactions null with correct large sample size. The methods are illustrated using data from the Tennessee class size reduction experiment Project STAR. The application suggests that differences in peer group quality were an important source of individual‐level variation in the academic achievement of Project STAR kindergarten students.  相似文献

Over the past two decades, state and federal restrictions of public smoking have become increasingly common. The resulting controversy has generally focused on the research evidence regarding the physiological effects of second-hand smoke while ignoring relevant psychological aspects of smoker-nonsmoker conflict. In this article I review the literature on the psychological consequences of smoker-nonsmoker interaction, interpreting these results from the framework of social psychological research on inter-group conflict. From this review I conclude that: a) smoker-nonsmoker conflict shares many characteristics of other ingroup-outgroup interactions; b) both groups are served by the legislated separation of these groups; and c) such separation can be successfully accomplished only when close attention is paid to subtle environmental cues. Finally, theoretical benefits of studying smoker-nonsmoker conflict from a social psychological perspective are discussed.  相似文献
