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 used data from a randomized controlled study of Oxford House (OH), a self-run, self-supporting recovery home, to conduct a cost-benefit analysis of the program. Following substance abuse treatment, individuals that were assigned to an OH condition (n = 68) were compared to individuals assigned to a usual care condition (n = 61). Economic cost measures were derived from length of stay at an Oxford House residence, and derived from self-reported measures of inpatient and outpatient treatment utilization. Economic benefit measures were derived from self-reported information on monthly income, days participating in illegal activities, binary responses of alcohol and drug use, and incarceration. Results suggest that OH compared quite favorably to usual care: the net benefit of an OH stay was estimated to be roughly $29,000 per person on average. Bootstrapped standard errors suggested that the net benefit was statistically significant. Costs were incrementally higher under OH, but the benefits in terms of reduced illegal activity, incarceration and substance use substantially outweighed the costs. The positive net benefit for Oxford House is primarily driven by a large difference in illegal activity between OH and usual care participants. Using sensitivity analyses, under more conservative assumptions we still arrived at a net benefit favorable to OH of $17,830 per person.  相似文献

Fostering participant engagement is a challenging but essential component of effective prevention programs. To better understand which factors influence engagement, this study examines several predictors of couple engagement in Family Foundations (FF), a preventive intervention for first-time parents shown to enhance parent mental health, couple relations, parenting quality, and child adjustment through age 3 years. FF consists of a series of classes delivered through childbirth education departments at local hospitals. Baseline data on socio-demographics, parent mental health, and couple relationship quality were examined as predictors of participants’ level of engagement in FF (n = 89 couples, 178 individuals). Sociodemographic variables such as parent gender, socioeconomic status, and age predicted program engagement to a limited extent. However, findings indicated that marital status was the best predictor of engagement. Discussion focuses on how findings can inform the development of practices that promote engagement, such as the use of targeted outreach efforts for individuals most at risk of disengagement.  相似文献

The purpose of this study is to describe the types of programs and mental health services former system youth with mental health histories would be inclined to engage in to manage their mental health difficulties, along with the factors that might hinder them from engaging in these services. A series of closed and open-ended questions on potential programs and services were asked, as part of a larger study. Participants were former system youth; specifically 18?C30?year olds who were diagnosed with a mood disorder and were involved with public mental health and social services (e.g., public welfare, child welfare, juvenile justice) during childhood. Responses to the open-ended questions were categorized and percentages are reported from the yes/no items. Eighty-three percent and 76% reported that they would be enticed to come to a support group and panel discussion on mood disorders, respectively, while only 46% reported that they would attend a family support group. Talking with others who have had similar experiences, material possessions and creative expression were the most common responses regarding what would entice them to get involved. Further, peer disrespect, transportation, and daycare were common barriers to potential participation. As the field continues to build knowledge on system-wide strategies to improve agency-based mental health care for transitioning youth and young adults, new evidence-based approaches may benefit from listening to the specific needs, preferences, and suggestions of these youth themselves.  相似文献

This paper investigates the influence of economic news on consumer sentiment, and examines whether “news shocks”—changes in coverage that would not be expected from incoming data on economic fundamentals—have aggregate effects. Using monthly U.S. data and a structural vector autoregression, I find that (1) sentiment is affected by news shocks; (2) after filtering out effects of news shocks, shocks to sentiment still have positive effects on consumer spending; and (3) news shocks influence both spending and unemployment in significant, though transitory ways. These results are consistent with other evidence of a role of nonfundamental factors in aggregate fluctuations. (JEL E21, E32, D12)  相似文献

We measured the use of patronizing speech among young adults who were instructed to provide directions (via an internet connection) to a newcomer to campus described as 21 or 65?years old. As predicted, the acoustic properties used with older adults were moderated by the speakers?? history with older unrelated adults (no comparable effects were found for speakers?? history with grandparents). Participants with relatively low contact with unrelated older adults were more likely than those with high contact to be judged as sounding ??patronizing?? and to display acoustical properties associated with patronization (high vocal intensity, high pitch) with older newcomers. However, participants showed a shared tendency to speak more slowly to older than young adults. Findings inform our understanding of the circumstances under which ageist speech is amplified or attenuated.  相似文献

The overarching aim of this article is to review the research on relationship education programs and approaches that has been published or accepted for publication since the last review article in 2003. This article provides a critical overview of the relationship education field and sets an agenda for research and practice for the next decade. A theme weaved throughout the article is the ways in which relationship education is similar and different from couples therapy, and we conclude that there can be a synergistic, healthy marriage between the two. We then provide recommendations for future directions for research in the relationship education field. Finally, the coauthors comment on our experiences in both the relationship education field and the couples therapy field as both researchers and interventionists.  相似文献

Intervention research for couples and families managing chronic health problems is in an early developmental stage. We reviewed randomized clinical trials of family interventions for common neurological diseases, cardiovascular diseases, cancer, and diabetes, which is similar to the content of previous reviews discussed later. One overriding theme of these studies is that patients with chronic illnesses and their families face a variety of challenges to which researchers have responded with an array of treatment modalities. Very few of the interventions reviewed, with the exception of treatment for adolescents with diabetes, tested family psychotherapy models. Most interventions were time-limited therapeutic interventions that trained families to improve their communication and problem-solving skills, individual and family coping skills, and medical management. Researchers more clearly described mechanisms of change in intervention studies with cancer and diabetes than with other diseases, and not surprisingly, they found greater empirical support for their interventions. Family interventions show promise to help patients and family members manage chronic illnesses. To develop an empirical base for family approaches to managing chronic illnesses, interventions must be based on theories that delineate mechanisms of change in family processes and skills in medical management necessary to maintain patients' and family members' health.  相似文献

Worldwide, strategic urban planning is found in very different contexts and planning schemes, where it is always a tool strongly linked to enhancing urban management. Under the umbrella of strategic urban planning different approaches can be perceived, in which within these broad shared characteristics there are significant variations. A key component in the strategic urban planning process is the monitoring and evaluation (M&E) element and these differences can be seen in the way that M&E is approached. Egypt is currently on the track to reform its planning system shifting from the conventional master plans towards strategic urban plans (SUPs). This paper reflects on the current practices of M&E the preparation of SUPs within the Egyptian context. It sheds light on the strengths and weaknesses of the employed techniques and concludes with some recommendations to improve the process of M&E, which builds upon the strengths in the employed techniques.  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
