About 50?years ago, Efron noted some counterintuitive properties of the long-term behavior of contests involving dice. For instance, consider the 6-sided dice whose sides are labeled (4,4,4,4,0,0), (3,3,3,3,3,3), (6,6,2,2,2,2), and (5,5,5,1,1,1). Each die has a 2/3 probability of rolling a higher number than the next one in the list and the last has the same 2/3 probability of rolling a higher number than the first. The non-transitivity of games involving non-identical dice was popularized by Gardner (Sci Am, 223:110–114, 1970). Although Gardner and other authors have observed that non-transitive dice serve to illustrate the complexities of the theory of voting, it does not seem that much attention has been paid to the corresponding voting system. Our purpose in this article is to present this voting system and compare its properties with those of other voting systems. One of the most interesting properties is the fact that cancellation with respect to the Efron dice voting system can replace cancellation with respect to pairwise preferences in Young’s characterization of the social choice function associated with the Borda Count. 相似文献

We present data on predictors of treatment outcome for 3200 consecutive referrals to a child and adolescent psychiatry clinic. Using Reliable Change Index (RCI) methodology, we divided children into those who, between intake and discharge, improved, stayed the same, or got worse according to clinician-rated impairment. Most predictors of improvement were related to parent variables (marital status, maternal anxiety, and ethnicity), while those associated with deterioration were tied to child status (extent of psychiatric comorbidity, history of placement in a self-contained classroom, and a prior trial of psychotropic medications). The implications of these findings for data-driven program development, clinic management, treatment planning, and systems of care are discussed. 相似文献

Specific efforts by hospital accreditation organizations encourage renovation of nursing stations, so nurses can better see, attend, and care for their patients. The purpose of this study was to examine the effect of nursing station design on the therapeutic milieu in an adult acute care psychiatric unit. A repeated cross-sectional, pretest-posttest design was used. Data were collected from a convenience sample of 81 patients and 25 nursing staff members who completed the Ward Atmosphere Scale. Pretest data were collected when the unit had an enclosed nursing station, and posttest data were collected after renovations to the unit created an open nursing station. No statistically significant differences were found in patient or staff perceptions of the therapeutic milieu. No increase in aggression toward staff was found, given patients' ease of access to the nursing station. More research is needed about the impact of unit design in acute care psychiatric settings. 相似文献

Older adults with multiple pre-existing conditions are admitted to hospitals with acute illnesses and injuries every day. Delirium is not recognized by clinicians across health care settings. With awareness of risk factors and knowledge of delirium, nurses can play a pivotal role in the early identification, treatment, and, most important, prevention of delirium in older adults. Nurses often display a lack of knowledge related to delirium and the complex symptoms that appear differently in the presence of other complicating co-morbid conditions in aging adults. Nurses play a crucial role in keeping patients safe and ensuring optimal outcomes, regardless of the setting. With the growing population of older adults and the expected increases in chronic illness and dementia, delirium is a problem nurses are likely to experience in all practice settings. Knowing what to look for facilitates recognizing the risk and acting early to minimize (or even prevent) delirium. 相似文献

Use of synthetic marijuana (also known as spice, K2, aroma, and eclipse) is often viewed by young people as harmless recreation. Until recently, the substance was freely available in U.S. convenience stores and head shops, and it is still available via the Internet. Emerging evidence shows a wide range of responses to the drug, including paranoia, aggressive behavior, anxiety, and short-term memory deficits. Synthetic cannabinoids are not currently detectable via standard toxicology tests. Recognition and management of synthetic cannabinoid use are discussed. 相似文献

Organizational institutionalism has shown how institutional entrepreneurs can introduce new logics into fields and push for
their broader acceptance. In academic science in the United States, however, market logic gained strength without such an
entrepreneurial project. This article proposes an alternative “practice selection” model to explain how a new institutional
logic can gain strength when local innovations interact with changes outside the field. Actors within a field are always experimenting
with practices grounded in a variety of logics. When one logic is dominant, innovations based on alternative logics may have
trouble gaining the resources they need to become more broadly institutionalized. But if a changing environment starts systematically
to favor practices based on an alternative logic, that logic can become stronger even in the absence of a coherent project
to promote it. This is what happened in US academic science, as growing political concern with the economic impact of innovation
changed the field’s environment in ways that encouraged the spread of local market-logic practices. 相似文献

This article draws upon recent works in sociology, jurisprudence, and feminist theory in order to assess the ways in which
feminism, and sex and gender more generally, have become intricately interwoven with punitive agendas in contemporary US politics.
Melding existing theoretical discussions of penal trends with insights drawn from my own ethnographic research on the contemporary
anti-trafficking movement in the United States—the most recent domain of feminist activism in which a crime frame has prevailed
against competing models of social justice—I elaborate upon the ways that neoliberalism and the politics of sex and gender
have intertwined to produce a carceral turn in feminist advocacy movements previously organized around struggles for economic
justice and liberation. Taking the anti-trafficking movement as a case study, I further demonstrate how human rights discourse
has become a key vehicle both for the transnationalization of carceral politics and for the reincorporation of these policies
into the domestic terrain in a benevolent, feminist guise. I conclude by urging greater and more nuanced attention to the
operations of gender and sexual politics within mainstream analyses of contemporary modes of punishment, as well as a careful
consideration of the neoliberal carceral state within feminist discussions of gender, sexuality, and the law. 相似文献
