China's rapid economic reforms, coupled with the changes in age composition of the demographic structure, have greatly affected the traditional family support system. In response to these changes, efforts to develop new models of community-based long-term care (CBLTC) for elders in China have received growing attention. This paper provides a systematic analysis of the current status of emerging CBLTC systems in Shanghai, China. It covers several domains of the system: service delivery, workforce, financing, and quality of care management. Several main issues involved in the development of the emerging system are addressed, and relevant policy implications are presented in the paper.  相似文献

The number of Arrovian constitutions, when N agents are to rank n alternatives, is p(n) p(n) N , where p(n) is the number of weak orderings of n alternatives. For n≤15, p(n) is the nearest integer to n!/2(log2) n +1, the dominant term of a series derived by contour integration of the generating function. For large n, about n/17 additional terms in the series suffice to compute p(n) exactly. Received: 29 May 1995 / Accepted: 22 May 1997  相似文献

This article is a continuation of analyses of cursillo. The specific concerns addressed are the development of the appropriate linguistic skills, that is, learning how to “talk the talk “of cursillo, and the development of the appropriate behavioral skills, that is, learning how to “walk the walk” of cursillo. When these skills are developed and used appropriately a form of ranked status mobility within a cursillo center can occur.  相似文献

Globalization has brought about fundamental change. But, the same theory that shows that free trade is beneficial also shows that globalization can be harmful to at least one of the trading countries. Moreover, with globalization, the interests of a country and its companies may diverge. In this paper, we examine free trade in a globalizing world and identify the key policy issues that economists and industrial leaders, alike, must address in today's interdependent world.  相似文献

A RELATIONAL EVENT FRAMEWORK FOR SOCIAL ACTION   总被引:2,自引:0,他引:2  
Social behavior over short time scales is frequently understood in terms of actions, which can be thought of as discrete events in which one individual emits a behavior directed at one or more other entities in his or her environment (possibly including himself or herself). Here, we introduce a highly flexible framework for modeling actions within social settings, which permits likelihood-based inference for behavioral mechanisms with complex dependence. Examples are given for the parameterization of base activity levels, recency, persistence, preferential attachment, transitive/cyclic interaction, and participation shifts within the relational event framework. Parameter estimation is discussed both for data in which an exact history of events is available, and for data in which only event sequences are known. The utility of the framework is illustrated via an application to dynamic modeling of responder radio communications during the early hours of the World Trade Center disaster.  相似文献
