戴卫·戈德尔是继罗尔斯之后 ,对契约主义思想影响最大 ,同时也带来了最多争议的思想家之一。他从塑造理想市场的需要出发界说人的道德与理性 ,认为二者同市场的运行原则———有限制最大化是和谐一致的。道德与理性的一致性假设虽然能够有效解决市场分析中的市场失灵问题 ,但是 ,这一假设本身依赖于一个理想市场的优先存在。两个假设的相互依赖最终使得戈德尔的道德学说陷入了解释学的循环 相似文献

This article describes the planning, decision-making, implementation, and evaluation phases of a recent, successful merger of five small social service agencies in Grand Rapids, Michigan. The merger was undertaken as a conscious strategy to enable the newly formed Arbor Circle Corporation to cope more effectively with environmental uncertainty, especially in regard to government contracting. The successes and the struggles encountered in the merger are instructive for other nonprofits that may be contemplating this kind of organizational restructuring as well as those interested in the impact of contracting on the government-nonprofit relationship. 相似文献

Over the past two decades, questions have surfaced about the effectiveness and contribution of intelligent systems to decision makers in a variety of settings. This paper focuses on the evaluation challenges associated with intelligent real‐time software systems that are embedded in larger host systems. With the proliferation of such systems in operational settings such as aerospace, medical, manufacturing, and transportation systems, increased attention to evaluations of such systems, and to resulting software safety, is warranted. This paper describes one such evaluation and proposes a set of evaluation criteria for embedded intelligent real‐time systems (EIRTS). Implications of the evaluation and the evaluation criteria are discussed. 相似文献

Little is known about factors associated with child welfare case duration. Understanding factors associated with case duration may help stakeholders make more informed decisions about funding and service allocation and improve compliance with federal law. This study had two research questions: (1) What factors are associated with child welfare case duration? And (2) Do factors differ depending on whether children were placed exclusively with parents or with others (e.g. relatives and foster care) during the case? The study sample consisted of families (N = 874) with co-occurring child maltreatment and substance use in one midwestern state in the United States between 2007 and 2016. Linear regression models were used to identify correlates of case duration while controlling for child placement status. Overall, having a child under 1 year of age, benzodiazepine use, methamphetamine use and injection drug use were all associated with longer case duration, whereas marijuana use with no other substance use was associated with shorter case duration. Additionally, factors associated with case duration differed based on child placement status during the case. These findings suggest important heterogeneity in families involved with child welfare services and may allow for proactive mitigation of cases at greater risk. 相似文献

In a survey exploring the reliability and validity of a screening tool, we explored the substance abuse and mental health issues among 371 elders; 74 were sexual minorities. Analyses by age group indicated that elders 55-64 years had significantly more problems with substance abuse, posttraumatic stress disorder (PTSD), depression, anxiety, and suicidal thoughts compared to those 65 and older. Bisexuals reported significantly greater problems with depression, anxiety, and suicidality than either heterosexual or lesbian or gay elders. Mental health and substance abuse treatment utilization was low among all elders with problems. Implications for assessment, access to care, and group-specific services delivery are discussed. 相似文献

This paper develops asymptotic optimality theory for statistical treatment rules in smooth parametric and semiparametric models. Manski (2000, 2002, 2004) and Dehejia (2005) have argued that the problem of choosing treatments to maximize social welfare is distinct from the point estimation and hypothesis testing problems usually considered in the treatment effects literature, and advocate formal analysis of decision procedures that map empirical data into treatment choices. We develop large‐sample approximations to statistical treatment assignment problems using the limits of experiments framework. We then consider some different loss functions and derive treatment assignment rules that are asymptotically optimal under average and minmax risk criteria. 相似文献

目前我国翻译界正处于解构主义多元化研究阶段,随着对解构主义翻译观的了解,其观点的极端和荒谬也进一步显露出来,尽管如此,解构主义翻译观仍然给我们的研究带来新的视野,令我们反思国内译学研究停滞的客观因素,为今后译学研究的发展做出积极尝试。通过对比,我们会发现传统翻译理论的全面与成熟,更加适合汉外的翻译研究。 相似文献
