Third sector organizations are transitioning towards entrepreneurial and managerial models as a result of quasi‐market strategies. This paper reports on the research findings of a survey of nonprofit disability organizations in Queensland and Victoria impacted upon by quasi‐market reform. Enterprising organizations were found to have made substantial change to organizational structures and systems, whilst more traditional organizations made few changes. All organizations demonstrated commitment to a social justice ethos. However across the organizational archetypes there were reports of an organizational ‘fragility’. It is argued that the problems of sustainability of community service organizations that existed prior to quasi‐market reforms remain. This implies community service organizations will experience ongoing difficulties in the post‐market era without further rationalization and change. A conceptual framework for sustainability of the community service sector is presented at the policy and organizational level.  相似文献

A necessary and sufficient condition for linear aggregation of SSB utility functionals is presented. Harsanyi's social aggregation theorem for von Neumann–Morgenstern utility functions is shown to be a corollary to this result. Two generalizations of Fishburn and Gehrlein's conditional linear aggregation theorem for SSB utility functionals are also established.  相似文献

Understanding long-term environmental risks   总被引:1,自引:0,他引:1  
How well we manage long-term environmental risks depends on how well we understand them. Whether the risk managers are experts or laypeople, that understanding is typically limited. As a result, people must rely on judgment when making decisions about risks. Estimating how big risks are and how much reducing them is worth is an intellectual skill. After reviewing the behavioral principles that govern how people acquire such skills, this article offers several proposals for facilitating learning abut risks by improving the ways in which scientific data are created or presented. It also describes some pitfalls facing attempts to determine the quality of other people's understanding of risks, whether through direct study or more casual observation.Preparation of this article was supported by National Science Foundation Grant SES-8846459.

Family caregivers of persons with advanced cancer often take on responsibilities that present daunting and complex problems. Serious problems that go unresolved may be burdensome and result in negative outcomes for caregivers’ psychological and physical health and affect the quality of care delivered to the care recipients with cancer, especially at the end of life. Formal problem-solving training approaches have been developed over the past several decades to assist individuals with managing problems faced in daily life. Several of these problem-solving principles and techniques were incorporated into ENABLE (Educate, Nurture, Advise, Before Life End), an “early” palliative care telehealth intervention for individuals diagnosed with advanced cancer and their family caregivers. A hypothetical case resembling the situations of actual caregiver participants in ENABLE that exemplifies the complex problems that caregivers face is presented, followed by presentation of an overview of ENABLE’s problem-solving key principles, techniques, and steps in problem-solving support. Though more research is needed to formally test the use of problem-solving support in social work practice, social workers can easily incorporate these techniques into everyday practice.  相似文献

The organizational context in which social work is practiced is viewed as an important factor in evaluating the outcomes of social work interventions. In host organizations, the context includes forces outside the department. The author offers a framework for developing a research agenda aimed at assessing the effectiveness of social work interventions in those organizations. The author demonstrates such an agenda with reference to hospital social work. Different types of outcomes and the relationships between them are considered at both the correlational and causal levels of knowledge. Examples of research assessing these outcomes are presented, and the implications of various types of findings are considered.  相似文献

This article provides an overview of intergenerational service- learning, an experiential pedagogy that involves students in learning outside the traditional classroom while providing a needed service in the community. Examples of intergenerational service-learning projects are presented that have been successfully utilized by the authors. These projects demonstrate the importance of using reflective practice assignments to help students deconstruct and reconstruct images, beliefs and paradigms about older adults. In addition, problems and opportunities in developing service-learning projects in urban and rural settings and with the Hispanic community are described, as well as some of the types of learning that may result from implementing service-learning experiences in various social work foundation courses.  相似文献

The conventional expected utility of a lottery establishes a tight myopic lower bound on the probability of indefinitely avoiding economic ruin, the probability of survival. The analysis presented assumes that the decision maker is able to decline lotteries that are unacceptable in the expected utility sense. Application of the result to the assessment of utility functions is discussed.  相似文献

Luce and Krantz (1971) presented an axiom system for conditional expected utility. In this theory a conditional decision is a function whose domain is a non-null subevent and whose range is a subset of a set of consequences. Given a family of conditional decisions that is closed under unions of decisions whose domains are disjoint and under restrictions to non-null subevents, the second major primitive is an ordering of the family. Axioms were given that are adequate to construct a numerical utility function over decisions and a probability function over events for which the conditional expectation of the utility is order preserving. Several of the axioms are quite complex and seem a bit artificial, and the proof is very long. Here the structure is modified by adding to the set of outcomes a concatenation operation, and the representation theorem is modified by requiring that the utility function be additive over this binary operation as well as exhibiting the expected utility property. The advantages of this pair of changes are, first, it exploits the obvious fact that the union of consequences is itself a consequence; second, it reduces the mathematical burden carried by the set theoretic structure of conditional decisions and, as a result, the axioms can be made much easier to understand; and third, it permits a considerably shorter proof because one can draw more readily on known results. The major drawback of this approach is, of course, that it is inconsistent with the evidence that utility is not additive over consequences - at least, not over increasing amounts of a single good (diminishing marginal utility).This work was supported by a grant from the Alfred P. Sloan Foundation to the Institute for Advanced Study. I wish to thank P. C. Fishburn and F. S. Roberts for their comments.  相似文献

Rational choice on non-finite sets by means of expansion-contraction axioms   总被引:1,自引:0,他引:1  
The rationalization of a choice function, in terms of assumptions that involve expansion or contraction properties of the feasible set, over non-finite sets is analyzed. Schwartz's results (1976), stated in the finite case, are extended to this more general framework. Moreover, a characterization result when continuity conditions are imposed on the choice function, as well as on the binary relation that rationalizes it, is presented.  相似文献

Volunteerism is described and defined and then a model of the decision to volunteer is presented. Data from an archival analysis of volunteering after the September 11, 2001 attacks and an on-line survey of volunteers are presented in support of the model. Finally, the implications of increasing volunteerism for the solution of social problems are considered.  相似文献

In this paper a data based approach for identifying and modifying group problems in goal oriented groups is presented. Types of post session questionnaires, observational systems, and other data collection methods for ascertaining group process are presented. A step by step paradigm is proposed to guide group workers in the assessment and modification process. Case materials in children and adult groups are discussed in which specific strategies are exemplified. A program aimed at preventing a high frequency of group problems is also briefly described.  相似文献

This article unveils the voices of the international students of the Universiti Sains Malaysia by exploring their belongingness and community well-being in Malaysia. This study was conducted with 14 international students (seven males and seven females) studying at the Universiti Sains Malaysia for at least a year. A qualitative approach was employed using in-depth case interviews to examine the socio-cultural challenges they experienced while studying abroad. The specific challenges reported among the international students are their well-being in distinct aspects such as physical, mental, and emotional. This study seeks to explore the international students' reliability on conational communities for social support. When achieving belongingness with their conational friends, international students can flourish well in their current community in Malaysia, thus achieving social community well-being although they are far away. Besides maintaining established close friendships, the international students develop a sense of comfort and familiarity by forming new friendships with conational and other international students. Sharing similar backgrounds and nationalities, as well as experiences and struggles, are significant for international students in maintaining close friendships and situational harmony. This study highlighted the meaning behind physical and emotional distance, as well as the situation of “being temporarily abroad” and its relations to intimacy practices and belongingness in close friendships. The results presented in this article contribute to an increasing understanding of international students' challenges and the future of social harmony and community well-being while temporarily living in Malaysia. Correspondingly, as a result of this study, students will be more deferential of cultural differences and cross-cultural sensitivity, which will also help to decrease prejudice and discrimination.  相似文献

This paper explores how some widely studied classes of nonexpected utility models could be used in dynamic choice situations. A new "sequential consistency" condition is introduced for single-stage and multi-stage decision problems. Sequential consistency requires that if a decision maker has committed to a family of models (e.g., the multiple priors family, the rank-dependent family, or the betweenness family) then he use the same family throughout. Conditions are presented under which dynamic consistency, consequentialism, and sequential consistency can be simultaneously preserved for a nonexpected utility maximizer. An important class of applications concerns cases where the exact sequence of decisions and events, and thus the dynamic structure of the decision problem, is relevant to the decision maker. It is shown that for the multiple priors model, dynamic consistency, consequentialism, and sequential consistency can all be preserved. The result removes the argument that nonexpected utility models cannot be consistently used in dynamic choice situations. Rank-dependent and betweenness models can only be used in a restrictive manner, where deviation from expected utility is allowed in at most one stage.  相似文献

Since Esping‐Andersen presented the three worlds of welfare typology thesis, the study of the classification of welfare regimes has been dominated by his work and the debates surrounding it. This article is concerned with two important responses to his work. The first response is the development of welfare typologies based on the principle of decommodification. The second response is the concern that East Asian countries are underrepresented in the 18 members of the Organisation for Economic Co‐operation and Development (OECD) studied by Esping‐Andersen. As a result, there are calls for expanding the scope of the studies on the classification of welfare regimes to those in East Asia. This article makes contributions to these two responses by presenting two analytical tasks. The first task is to develop two health decommodification typologies based on two different methods (cluster analysis and Esping‐Andersen's index‐based regime construction). Both of them cover the 18 OECD members studied by Esping‐Andersen and four tiger economies (Hong Kong, Taiwan, South Korea and Singapore). The second task is to demonstrate that the two health decommodification typologies provide important information for the debate on the existence of two essential preconditions for the development of an all‐encompassing East Asian welfare regime, namely the existence of significant differences in the welfare systems between the East Asian countries and the 18 OECD countries studied by Esping‐Andersen (1990 ) and the existence of significant similarities in the welfare systems between East Asian countries.  相似文献

The role of risk preferences in determining the outcome to bargaining is examined for the case in which acceptance of a proposal requires less than unanimous approval. Using an n-agent extension of the Ståhl-Rubinstein alternating offer model, we find that risk preferences play a fundamentally different role when bargaining is settled using a nonunanimity voting rule. Risk preferences determine not only an agent's reservation price but also the likelihood that he is made part of the winning coalition. An implication of this analysis is that when the preferences of the agents are not too diverse, it is advantageous for an agent to be relatively risk-averse.The helpful comments and suggestions of Rich McLean and an anonymous referee are gratefully acknowledged. This article was presented as a paper at the 1988 Winter Econometric Society Meetings.  相似文献

《四库全书总目》是中国古代最系统的一部文化史、学术史,其中《集部》则是一部叙录体的中国文学批评史,而其大小序则是中国文学批评史提纲。《集部总序》讲《四库全书》集部分为五类的原因,认为集部的别出,是汉代文词自觉的结果,文词的自觉是文学自觉的重要标志。《楚辞类序》对《楚辞》别出一类的原因从传统和形式上作了分析,但未能像《隋志》那样从思想内容上阐述其独特的风格和别列的原因。《总集序》讲总集的源头和分类,它提出的《诗经》是集部之祖的观点,是对经学传统观的挑战。《诗文评序》把诗文评著作分成五类,并对各类的特点进行了简要分析;对“诗文评”在目录学中的地位嬗变作了说明,大体理清了中国文学批评史的发展脉络。  相似文献

Staying power in sequential games   总被引:1,自引:0,他引:1  
Staying power is the ability of a player to hold off choosing a strategy in a two-person game until the other player has selected his, after which the players are assumed to be able to move and countermove sequentially to ensure their best possible outcomes before the process cycles back to the initial outcome and then repeats itself (rational termination). These rules of sequential play induce a determinate, Paretosuperior outcome in all two-person, finite, sequential games in which the preferences of the players are strict.In 57 of the 78 distinct 2 × 2 ordinal games (73 percent), it makes no difference who the (second-moving) player with staying power is, but in the other 21 games the outcome is power-dependent. In all but one of these games, staying power benefits the player who possesses it.If no player has staying power, the outcomes that result from sequential play and rational termination are called terminal; they coincide with staying power outcomes if they are Pareto-superior. Normative implications of the analysis for rationally justifying cooperation in such games as Prisoners' Dilemma and Chicken, and implementing Pareto-superior outcomes generally, are also discussed.We are grateful to D. Marc Kilgour for very valuable comments on an earlier version of this paper, causing us to rethink and redefine staying power. The earlier version was presented at the Seventeenth North American Conference, Peace Science Society (International), University of Pennsylvania, November 9–11, 1981.  相似文献

Objective. We examine how the immigration policy preferences of Anglos and Latinos vary according to ethnic context. Specifically, we hypothesize that immigration policy attitudes are a product of both Latino immigrant and Latino native born group size. In contrast to previous work, which found that Latinos and Anglos react to contextual forces in an identical manner, we argue that Latino group size produces opposite reactions for Anglos and Latinos. Methods. These hypotheses are tested using an original state‐wide survey of Anglos and Latinos in Texas conducted during 2006, which is supplemented with data from the 2000 Census. Results. Our findings show that residing in a heavily Latino area produces more liberal immigration attitudes among Latinos and more conservative attitudes among Anglos. However, this result is driven not by the size of the foreign‐born Latino population, but by the size of the native‐born Latino population. Conclusion. Anti‐immigrant sentiments among Anglos appear to result, at least in part, from ethnic concerns.  相似文献
