We consider a cross‐calibration test of predictions by multiple potential experts in a stochastic environment. This test checks whether each expert is calibrated conditional on the predictions made by other experts. We show that this test is good in the sense that a true expert—one informed of the true distribution of the process—is guaranteed to pass the test no matter what the other potential experts do, and false experts will fail the test on all but a small (category I) set of true distributions. Furthermore, even when there is no true expert present, a test similar to cross‐calibration cannot be simultaneously manipulated by multiple false experts, but at the cost of failing some true experts. 相似文献

Consumer-directed service options in home- and community- based care are increasingly available to adults with chronic conditions and cognitive impairments and to their family caregivers. Few studies, however, examine the experience of family caregivers who, when given a choice of providers of respite assistance (i.e., relief from the stress of providing constant care), prefer to hire family or friends rather than service providers. This study describes the in-home respite experience of family caregivers served by California's Caregiver Resource Centers "direct-pay" program who hire family or friends (n = 39) or service providers (n = 77) to provide in-home respite assistance. Findings revealed similarities between the two groups with few exceptions: caregivers who hired family or friends reported poorer physical health, were slightly more satisfied with the respite assistance, and received more hours of respite at a lower unit cost. These findings lend support to consumer-directed respite service options where family caregivers are given flexible alternatives that may act to remove barriers to respite service availability and use. 相似文献

Preliminary experiences of the states in implementing the National Family Caregiver Support Program: a 50-state study 总被引:1,自引:1,他引:0
Despite increased attention to policy choices to support family and informal caregivers, relatively little is known about states' experiences in providing caregiver support services. This article reports on the first nationwide survey of all 50 states and the District of Columbia in providing caregiver services since the passage of the National Family Caregiver Support Program. State program administrators reported that their program differs from other home and community-based services because of the explicit focus on the family or informal caregiver. Results suggest that despite an increasing availability of caregiver supports in all 50 states, there is also a great unevenness in services and service options for family caregivers across the states and within states. 相似文献

The nature of operations executives’ strategic cognition, as the antecedent to their choices about operations strategy, remains underexplored in the literature. This mixed‐methods study examines executives’ thinking about supply chain strategy through the lens of managerial cognition. Our qualitative study at a pharmaceutical distributor, which examined 25 executives’ outlook on the future of the turbulent U.S. healthcare sector and their suggestions for adapting the company's supply chain strategy to that future, suggests that an executive's strategic cognition can be defined by its regulatory focus—whether the executive envisions the future environment in terms of opportunities or threats—and the level of optimism in regards to the envisioned future. We propose a typology that predicts the strategic choices of operations executives based on four types of cognition: pioneering, pushing, protective, and provocative. It describes whether an executive's strategic choices target traditional or novel sources of revenue, and if they seek to influence either the firm's structure and practices or its environment. Our empirical test of the typology using quantitative data collected in a survey of senior operations executives supports the study's propositions associating three of the four types of cognition with their respective preferred strategic choices. 相似文献

Previous research suggests that minorities are more likely to perceive racially-based discrimination in a variety of settings
than are whites, in large part because of the ways their personal experiences with racism shape the lens they use to view
the world. We examine a labor market that is typically considered an exception to patterns of racism in employment, the industry
of professional football. We interview athletes who attempted to gain employment in the National Football League, a labor
market where access to valued positions is heavily restricted by industry practices. Findings from field research and semi-structured
interviews indicate that minority workers experience symbolic discrimination during the hiring process. Differential treatment
of players reflects stereotypes about minority families and masculinity. Although minority and white players describe much
of the actual content of their labor market experiences in similar fashion, their perceptions of these experiences differ
sharply, with minority athletes identifying far more negative repercussions.

Because they often set out with a guarantee of only short-term funding, many community partnerships will face a threat to their sustainability almost as soon as the first money runs out. Research into the factors that enable some coalitions and partnerships to meet the challenge when others fail is limited. This study begins to fill this gap in our understanding by examining influences on the process of sustainability planning in the context of a collaborative partnership focused on youth development. We report on a longitudinal examination of the quality of planning and attitudes underpinning the sustainability of PROSPER community prevention teams whose members implement evidence-based programs designed to support positive youth development and reduce early substance use and other problem behaviors. The current research concentrates on a particular dimension of partnership effectiveness to establish whether perceptions about team functioning in play at 6 and 18 months predict the quality of sustainability planning at 36 and 48 months. How well teams functioned in the early stages was found to be strongly related to the quality of their later preparations for sustainability. Recruitment and integration of new team members, and the encouragement they subsequently received were also found to be key factors. The results strengthen the argument for providing technical assistance to meet the needs of those who promote prevention partnerships, and they provide longitudinal empirical data to support the hypotheses of other researchers who have similarly found a correlation between effective sustainability and early planning and support. 相似文献

Over the past decade, a new and intriguing phenomenon developed in Israel: close to 60,000 Israelis applied for citizenship in the Central and Eastern European countries from which their families immigrated. Typically, these new dual citizens have no plans to “return” to Germany or Poland, nor do they feel any identification with their countries of origin. Instead, they are mainly interested in obtaining a “European Union passport” and in gaining potential access to the European common market. The paper presents statistics on this unconventional case of dual citizenship, surveys the historical and legal circumstances that produced it and uses material from interviews to explore the meanings and uses that European‐Israeli dual citizens attribute to their European passports. Dual citizenship, the findings show, is used by Israelis in various and sometimes unexpected ways: as enhancer of economic opportunities, “insurance policy,” intergenerational gift, and even as an elitist status symbol. This modality of state belonging can be termed “passport citizenship”: Non‐resident citizenship here is stripped of its national meaning and treated as an individual piece of property, which is embodied by the passport and obtained for pragmatic reasons. 相似文献

In this paper, some possible relationships between psychopathology and pathological gambling are delineated. The assessment and stabilization of such patients, including psychotherapeutic and pharmacologic strategies, are discussed. Guidelines for treating patients manifesting both a psychiatric illness and a gambling problem are suggested. 相似文献
