营造“包容性空间”:国际化社区的治理策略研究

营造包容性空间,构建包容性社会,加快推进空间治理的现代化进程,是现代化治理的重要目标。基于江苏省南京市Q社区的空间营造案例,从社区空间营造策略的视角出发,剖析国际化社区如何营造包容性空间。研究发现,基层政府基于中国居民与外籍人士的空间服务需求,运用多元参与、互动协商、文化治理等软性手段,通过建设人与居住地、社会、自然相融合的表征的包容性空间,组织温度、服务与文化协同相融的包容性空间的实践,构筑开放、包容与共享的包容性空间的表征等方式营造包容性空间。在营造包容性空间的过程中,基层政府空间营造行动的关键策略是采用“分型管理、内育外引”的主体包容策略、“内外兼修、空间包容”的技术包容策略、“多元网格、协商自治”的制度包容策略及“制度共融、成果共享”的结果包容策略,其根本目标在于打造国际化社区的治理共同体。包容性空间的治理技术对优化基层政府的空间治理能力、提升居民的参与水平与再造国际化社区秩序有积极效应,但亦潜藏多主体协同失序、政社关系掣肘、族群关系区隔、文化不稳定及包容性制度偏差等失灵风险。因此,基层政府需厚植多主体合作的治理机制、经营包容性空间的“适度性”,以利于国际化社区善治目标的实现。     

Decision Analysis and Risk Management Decision Making: Issues and Methods

This paper provides an overview of decision analysis and its use in risk management decision making. The paper discusses the distinctive characteristics of decision analysis and compares these characteristics with those of its principal alternative—cost–benefit analysis. The paper also discusses each of the steps in a decision analysis and the strengths and limitations of the method.     

Gender roles,HIV risk behaviors,and perceptions of using female condoms among college students

The purpose of this study was to examine relationships between gender roles and HIV risk behavior, and perceptions and acceptance of the female condom among college students (n = 410). It was hypothesized that high hyperfeminine females and high hypermasculine males – those adhering to traditional gender roles – would engage in more HIV risk behaviors, including alcohol and drug use and various sexual practices, than those with lower hyperfemininity and hypermasculinity. It was also hypothesized that higher hyperfeminine females as well as higher hypermasculine males would perceive the female condom more negatively and would be less likely to view the female condom as a viable form of protection in the future. It was also hypothesized that high hyperfeminine females and high hypermasculine males would not accept the female condom as an alternative form of protection. Implications for prevention interventions are discussed.     

基于时变参数Copula的ΔCoVaR度量技术

采用基于时变参数Copula的ΔCoVaR度量方法,以动态参数Copula模型描述金融变量间的相依结构、以GARCH类模型描述各金融变量的边际分布,通过构建的联合分布计算ΔCoVaR。利用此方法度量中国大陆与美国、香港的股票市场间的极端风险溢出。实证结果表明:通过此方法计算的ΔCoVaR能同时反映时变波动性与时变相依性,可更灵敏准确地度量危机时的极端风险溢出。     

风险社会与媒介表征

风险社会的形成与大众媒介表征密不可分:大众媒介通过拟态环境的构建,形成了公众的风险感知,促成了风险传播的蝴蝶效应.在此基础上,探讨媒介形成社会风险的三方面成因:价值层面上,媒介的社会整合功能不足,价值培养欠缺;制度层面上,公益节目欠缺,政府信息制度贯彻不力;内容层面上:网络媒介的风险长尾效应日渐突出.

Dependence Estimation Over a Finite Bivariate Failure Time Region

This articleconcerns nonparametric estimation of association between bivariatefailure times. In the presence of independent right censoring,the support for failure time variates may be restricted and measuresof dependence over a finite failure time region may be of particularinterest. To this end, the reciprocal cross ratio function, weightedby the bivariate failure time density, is proposed as a summarymeasure of dependence over a failure time region. This `relativerisk' estimator is shown to be consistent and asymptoticallynormally distributed, with consistent bootstrap variance estimator.A finite-region version of Kendall's tau, which is suitable forcensored failure time data, is also proposed, and correspondingasymptotic distribution theory is noted. The accuracy of theseasymptotic approximations is studied in simulations and an illustrationis provided.     

A case–control study relating railroad worker mortality to diesel exhaust exposure using a threshold regression model

A case–control study of lung cancer mortality in U.S. railroad workers in jobs with and without diesel exhaust exposure is reanalyzed using a new threshold regression methodology. The study included 1256 workers who died of lung cancer and 2385 controls who died primarily of circulatory system diseases. Diesel exhaust exposure was assessed using railroad job history from the US Railroad Retirement Board and an industrial hygiene survey. Smoking habits were available from next-of-kin and potential asbestos exposure was assessed by job history review. The new analysis reassesses lung cancer mortality and examines circulatory system disease mortality. Jobs with regular exposure to diesel exhaust had a survival pattern characterized by an initial delay in mortality, followed by a rapid deterioration of health prior to death. The pattern is seen in subjects dying of lung cancer, circulatory system diseases, and other causes. The unique pattern is illustrated using a new type of Kaplan–Meier survival plot in which the time scale represents a measure of disease progression rather than calendar time. The disease progression scale accounts for a healthy-worker effect when describing the effects of cumulative exposures on mortality.     

Reliability acceptance sampling plans for the Weibull distribution under accelerated Type-I censoring

Type-I censored reliability acceptance sampling plans (RASPs) are developed for the Weibull lifetime distribution with unknown shape and scale parameters such that the producer and consumer risks are satisfied. It is assumed that the life test is conducted at an accelerated condition for which the acceleration factor (AF) is known, and each item is continuously monitored for failure. Sensitivity analyses are also conducted to assess the effect of the uncertainty in the assumed AF on the actual producer and consumer risks, and a method is developed for constructing RASPs that can accommodate the uncertainty in AF.
