If preferences are continuous monotone complete preorders, then there is a continuous social choice aggregation rule which respects unanimity and is anonymous. The simple proof of this result involves a straightforward application of well-known properties of the closed convergence topology. 相似文献

This paper examines the efficacy of the United Mine Workers of America (UMWA) in achieving safe working conditions by reducing
the probability of severe injury. A detailed data base has been constructed for underground mines during the period 1986–1988.
The results obtained fail to provide convincing evidence that the UMWA reduces the severity of injury, even though the UMWA
has safety committees and inspectors in the mines where it is the bargaining agent. Further testing reveals that there is
no significant difference in the probability of injury due to roof falls, haulage, and handling material, between union and
nonunion mines. 相似文献

As U.S. cities accommodate increasing ethnic and racial diversity, political choices may unify or divide their local populations. Those choices pull communities toward two different modes of pluralism: traditional “melting pot” assimilation or a complex mosaic of racial and ethnic assertiveness. Central to this issue is equity and empowerment, which may be accentuated by minority populations’ size, structure, and spatial concentration. We examine two potential modes of local empowerment: “dominance,” whereby each group is the majority of voters in single election districts (reinforcing separative tendencies), and “influence,” whereby a group gains “influential minority” status in several districts (reinforcing unifying tendencies). 相似文献

Summary. When experimentation on a real system is expensive, data are often collected by using cheaper, lower fidelity surrogate systems. The paper concerns response surface methods in the context of variable fidelity experimentation. We propose the use of generalized least squares to generate the predictions. We also present perhaps the first optimal designs for variable fidelity experimentation, using an extension of the expected integrated mean-squared error criterion. Numerical tests are used to compare the performance of the method with alternatives and to investigate the robustness to incorporated assumptions. The method is applied to automotive engine valve heat treatment process design in which real world data were mixed with data from two types of computer simulation. 相似文献

Maltreatment and Trauma: Toward a Comprehensive Model of Abused Children from Developmental Psychology 总被引:1,自引:0,他引:1
Jack Weitzman 《Child and Adolescent Social Work Journal》2005,22(3-4):321-341
Knowledge of how maltreatment and trauma aects personality functioning in abused children has been greatly enhanced by clinical
theory and research in developmental psychology. Developmental research and theory has allowed the child abuse field to move
beyond symptom-lists toward broader models of how trauma impacts major domains of personality functioning. However, these
models continue to be based largely on discrete theories of development that parallel, if not confound, one another. This
paper attempts to expand our understanding of the traumatized child by using the synthetic model of personality development
expounded by Fred Pine that promotes a more holistic and comprehensive view of the abused child and, thus, enhances clinical
theory and intervention. 相似文献

In this article, a new element is introduced into the household production function: gifts. Gifts occur when spouses use their time and/or incomes to produce commodities that usually only have value to their spouse, such as empathy and understanding. The difficulty of identifying a potential mate's capacity to produce gifts prior to marriage and of negotiating for them during marriage is argued as having contributed to the increase in the divorce rate. Evidence is provided that women are the spouses most likely to seek a divorce and part of their motivation is an inadequate receipt of gifts during marriage. 相似文献

The debate about the veracity of incest memories uncovered in therapy is often impassioned and acrimonious. Recent statements by various professional organizations, advising that corroboration of recovered memories is the only method for determining their accuracy, have not decreased the intensity of this debate. This response to Madden and Parody's paper discusses the importance of corroboration of recovered memories of sexual abuse and details the clinical, scientific, and legal foundations for this approach. A point of confusion in Madden and Parody's paper and an important aspect of this response is the difference between clients who uncover completely new memories of childhood sexual abuse and clients who enter therapy with a history of sexual abuse. Those clients with new memories are the focus of this debate and the standard of care proposed in this paper. 相似文献
