Major late life events, reported in the Dubbo longitudinal study of older Australians, are used to examine the interaction of private lives with public programs. First, the data indicate strong supportive effects of publicly funded income, health, and aged care programs in reducing family burdens from major life changes. In particular, financial crises were rarely mentioned, directly or indirectly, as major threats. Next, the central role of informal social support in these events is demonstrated, first, as in previous studies, family support was responsive to risky events and to aging itself. Also, in new findings, one-third of surviving elderly respondents coped with the burdens of family crises as a substantial proportion of the "major" life changes that occurred over 13 years of the study. Within the security and support provided by the Australian welfare system, and with strong social networks, families with older persons in the Dubbo study manage multiple, major life changes. With rapid population aging, the development of more, and more easily accessible, services for a growing population of older people is a priority. The critical challenge will be to harmoniously grow public financing, private funding, and informal caregiving to deal with the growing burden arising from an aging society. 相似文献

The subject of this article is the simultaneous choice of product price and manufacturing capacity if demand is stochastic and service‐level sensitive. In this setting, capacity as well as price have an impact on demand because several aspects of service level depend on capacity. For example, delivery time will be reduced if capacity is increased given a constant demand rate. We illustrate the relationship between service level, capacity, and demand reaction by a stylized application problem from the after‐sales services industry. The reaction of customers to variations in service level and price is represented by a kinked price‐demand‐rate function. We first derive the optimal price‐capacity combination for the resulting decision problem under full information. Subsequently, we focus on a decision maker (DM) who lacks complete knowledge of the demand function. Hence the DM is unable to anticipate the service level and consequently cannot identify the optimal solution. However, the DM will acquire additional information during the sales process and use it in subsequent revisions of the price‐capacity decision. Thus, this decision making is adaptive and based on experience. In contrast to the literature, which assumes certain repetitive procedures somewhat ad hoc, we develop an adaptive decision process based on case‐based decision theory (CBDT) for the price‐capacity problem. Finally, we show that a CBDT DM in our setting eventually finds the optimal solution, if the DM sets the price based on absorption costs and adequately adjusts the capacity with respect to the observed demand. 相似文献

This paper discusses the constructivist, negotiated perspective to INGO accountability. According to this perspective, INGO accountability is a process of mutual negotiations between different INGO stakeholders who hold different accountability demands. Acknowledging that this perspective provides a good starting point for a better understanding of INGO accountability, we comment on this conceptualization of INGO accountability. Through an analysis of accountability instruments and procedures, we examine closely how the demands of the INGO’s stakeholders are embedded in particular relationships of accountability which are sustained by particular accountability logics. From this analysis, we point out that, due to the differences that exist between these accountability logics, processes of negotiation are likely to be filled with complex tensions and trade-offs. Moreover, as some accountability logics are much clearer and more compelling than others, a constructivist perspective on INGO accountability does not automatically coincide with an understanding of INGO accountability in which primordial importance is given to the beneficiaries. 相似文献

The recent U.S. recession has resulted in higher rates of unemployment, underemployment, and child poverty, with African Americans disproportionately represented among the financially disadvantaged. Although past research has established the relationship between family financial hardship and various child adjustment problems, African Americans remain an understudied group. In the current study the authors used longitudinal data from the Family and Community Health Study (n = 422), an all African American sample, to investigate the impact of economic distress on adolescent conduct problems. They examined the extent to which this relationship can be explained by 2 frequently employed models: (a) the family stress model and (b) the family investment model. The authors extend past research by assessing the relative contributions of each model while controlling for the paths proposed by the other model. The results suggest that the family processes identified by the family stress model provide a more accurate explanation for why economic hardship is associated with increased conduct problems among African American adolescents. 相似文献

We discuss the quite remarkable global Markovian structure of the nucleotides in eukaryotic DNA strands with special emphasis on (i) the similarity property for intra- species chromosomes and (ii) the reversibility property for the two (complementary) strands of a chromosome. 相似文献

Since Eli Goldratt first appeared on the scene in the late 1970s, his ideas concerning production management have generated a huge amount of interest, controversy, and misunderstanding. These ideas have been proliferated under several names such as optimized production technology (OPT), drum-buffer-rope (DBR), synchronized manufacturing (SM), and theory of constraints (TOC). Although there seems to be general agreement on the importance of how capacity-constrained resources are scheduled, research aimed at advancing the state of the art for the specific problem addressed by DBR continues to be limited by prior misunderstandings and the lack of a rigorous examination by the academic community. This paper seeks “to advance the state of research on constraint scheduling in several ways. First, it presents a concise history of the evolution of DBR. It then explains the use of rods in constraint scheduling. Next, it presents in detail the solution algorithm incorporated by the Goldratt Institute in their production software and, finally, relates that algorithm to alternative methods. In the process of these activities, several lingering misconceptions are resolved. 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

In-depth interviews were conducted with a sample of 25 persons recently convicted of homicide in a largely rural, midwestern state. The primary focus of the study was the definition of the situation, particularly the vocabulary of motives, employed by the respondents at the time of their crime. The results showed that the vast majority of the respondents cited motives involving excuses (e.g., it was an accident, judgment impaired by alcohol/drugs, not oneself because of severe stress). These excuses assumed, or appealed to, conventional moral views of violence. Six of the individuals provided motives that they felt justified their actions. However, these justifications tended to be based upon a plea of self-defense and demonstrated a commitment to conventional morality rather than to the norms of a violent subculture. There was no evidence that the respondents viewed their behavior as part of a character contest. In most instances, they were unemployed or underemployed persons, living rather dead-end lives, who in the course of mounting life stress struck out at someone, usually while intoxicated. Frequently they were depressed, and in some cases suicidal, at the time of the act, and the victim was usually a relative or friend. In half of the cases it appeared that the homicide would not have taken place if a handgun has not been present. 相似文献

We propose an approach to service–learning in which projects are designed so as to empower undergraduate students and community members. When student service scholars take away control from citizens, they can undermine citizens' perceptions of competency; when faculty reduce students' choice and responsibility, they can undermine students' efficacy and desire to learn. We propose four guidelines for optimizing student and citizen experiences: (1) service should serve both the community and the students; (2) service should empower; (3) service should be contextual; and (4) service projects should endure. We elaborate this philosophy and illustrate it with a project in which nine university students and 30 fifth–graders built a science and nature study center for a K–6 elementary school. 相似文献
