This article seeks to develop a paradigm for understanding the sociological meaning of narratives of surrender. Surrenders are boundary events in time and in space. Coming at the end of conflicts, surrenders are transitional and transformative occasions during which the emotional and symbolic landscapes of power are traced and highlighted. They mark the site of trauma and, depending on the manner in which they are accomplished, can alternately emphasize the degradation of the vanquished or the magnanimity of the victor. Surrenders are analyzed as simultaneously historical events, symbolic events, and political events. 相似文献

This study analyzes subsidy schemes that are widely used in reducing waiting times for public healthcare service. We assume that public healthcare service has no user fee but an observable delay, while private healthcare service has a fee but no delay. Patients in the public system are given a subsidy s to use private service if their waiting times exceed a pre‐determined threshold t. We call these subsidy schemes (s, t) policies. As two extreme cases, the (s, t) policy is called an unconditional subsidy scheme if t = 0, and a full subsidy scheme if s is equal to the private service fee. There is a fixed budget constraint so that a scheme with larger s has a larger t. We assess policies using two criteria: total patient cost and serviceability (i.e., the probability of meeting a waiting time target for public service). We prove analytically that, if patients are equally sensitive to delay, a scheme with a smaller subsidy outperforms one with a larger subsidy on both criteria. Thus, the unconditional scheme dominates all other policies. Using empirically derived parameter values from the Hong Kong Cataract Surgery Program, we then compare policies numerically when patients differ in delay sensitivity. Total patient cost is now unimodal in subsidy amount: the unconditional scheme still yields the lowest total patient cost, but the full subsidy scheme can outperform some intermediate policies. Serviceability is unimodal too, and the full subsidy scheme can outperform the unconditional scheme in serviceability when the waiting time target is long. 相似文献

Dropping out of university: A statistical analysis of the probability of withdrawal for UK university students 总被引:4,自引:0,他引:4
Jeremy P. Smith & Robin A. Naylor 《Journal of the Royal Statistical Society. Series A, (Statistics in Society)》2001,164(2):389-405
From individual level data for an entire cohort of undergraduate students in the 'old' universities in the UK, we use a binomial probit model to estimate the probability that an individual will 'drop out' of university before the completion of their degree course. We examine the cohort of students enrolling full time for a 3- or 4-year degree in the academic year 1989–1990. We find evidence to support both the hypothesis that the completion of courses by students is influenced by the extent of prior academic preparedness and the hypothesis that social integration at university is important. We also find an influence of unemployment in the county of prior residence, especially for poorer male students. Finally, we draw conclusions regarding the public policy of constructing university performance indicators in this area. 相似文献

This paper draws on work carried out by Sen, Kendrick, Milligan and Hawthorn commissioned as pert of the Historic Abuse Systemic Review by the Scottish Executive in 2007. It considers the evidence‐based regarding abuse in residential child care from 1945 with a specific focus on Scotland. It reviews the context set for residential child care post‐1945 by the Clyde and Curtis reports, outlines how the residential child care sector developed following this, provides an overview of evidence and awareness of abuse in residential child care establishments after the 1948 Children's Act, giving particular consideration to the public inquiries and reviews of residential child care which there have been in Scotland, explores research evidence regarding the safety of convictions of residential child care workers found guilty of child abuse, and provides an overview of the main policy and practice developments which there have subsequently been in Scotland. The paper concludes by considering the progress that has been made in developing safeguards in Scotland and identifying areas where further research and development are required. 相似文献

This article reports an experiment which tests the principle of separability, i.e. that behaviour in a dynamic choice problem is independent of history and of unreachable eventualities. Although this is a well-known principle of orthodox decision theory and central to conventional economic modelling, it has been questioned on grounds suggested by non-expected utility models of choice under risk and by the psychology of affective influences on risk-taking. Our experimental design, which provides between-subjects tests of separability using three treatments in which the history preceding a decision is manipulated, is inspired by these concerns. We expose separability to a clean and harsh test, but find no evidence that it is violated. 相似文献

Using a sample of practitioners (n = 269) from the 2004 National Study of Licensed Social Workers, this article employs a quality assurance structure-process-outcome model to examine factors at the practitioner, workplace, and service delivery levels that influence the perceived efficacy of licensed gerontological social workers to affect client outcomes in the context of a highly challenging health care environment. A regression model accounted for 33.9% of the variance (adjusted R (2) = .291) in perceived efficacy with 3 aspects of service delivery satisfaction having significant effects: ability to address complex/chronic care, to influence the design of services, and to help clients navigate the system. 相似文献

We discuss event histories from the point of view of longitudinal data analysis, comparing several possible inferential objectives.
We show that the Nelson–Aalen estimate of a cumulative intensity may be derived as a limiting solution to a sequence of generalized
estimating equations for intermittently observed longitudinal count data. We outline a potential use for the theory in interval-censored
recurrent-event models, and demonstrate its applicability using data from a Toronto arthritis clinic. We also discuss connections
with rate models, along with some implications for the longitudinal analyst. 相似文献
