Abstract "Subsistence" and "informal economy" are contrasted in their utility as sociological concepts and their ability to explain a variety of activities in two rural Mississippi Delta communities. Literature on subsistence stresses that the desired outcome of participation is not an increase in income but the social rewards of participation itself. Two underlying dimensions of participation in these activities are documented through the literature and through a confirmatory factor analysis of empirical data: life-style choice and economic strategy. These were constructed into indexes and examined individually and in combination as dependent variables using regressors at the community, household, and individual levels. Community ties were weakly associated with participation in such activities. Whites and those with higher incomes participated more in lifestyle choice oriented activities. Participation in general was statistically related to households needing less weekly income and being of larger size. Potential connections with persistent rural poverty are discussed.  相似文献

This study investigated the relative effectiveness of specific genital regional self-stimulation in elevating pain thresholds. Anecdotal reports in humans suggest that sexual activity and orgasm decrease a wide variety of human responses to pain and touch, but the phenomenon has not been evaluated objectively. Two types of self-stimulation, pressure and pleasurable, were applied by 10 women to the anterior vaginal wall, the posterior vaginal wall, and the clitoris. Significant increases in pain thresholds but not tactile thresholds occurred when pressure stimulation was applied to the anterior wall of the vagina or when "pleasurable" self-stimulation was applied to any of the three areas. Tactile thresholds were not significantly affected by any genital stimulation condition. However, there was a significant increase in tactile threshold but not pain thresholds in the distraction control condition. On the basis of these findings, we conclude that (a) a sensation of pleasure evoked by genital stimulation can elevate pain thresholds, (b) these pleasurable stimuli were not general "distractants" because they elevated pain thresholds but not tactile thresholds differentially, and (c) genital pleasurable stimuli activate an analgesic process that is distinct from a distraction process.  相似文献

Patients' views of patient-physician interactions—particularly the perspectives of older, ethnically diverse women—are poorly understood. The older patient's attitude toward and understanding of the medical encounter, however, are essential to the design of strategies to improve patient-physician communication. To date, investigations have primarily emphasised the ways in which the therapeutic relationship is influenced by immutable patient characteristics. This qualitative study extends previous research findings by looking beyond the effect of ascribed categories (such as age, race, and gender) and focusing on aspects of patient behavior, specifically assertiveness. Focus groups were conducted with older African-, Chinese-, European-, and Hispanic American breast cancer patients from sites in the eastern and western United States. The study explores the potential of a form of patient activation for challenging stereotypes of the elderly and changing health care practitioners' behavior.  相似文献

This Issue Brief provides an overview of the issues relating to the Employee Retirement Income Security Act of 1974 (ERISA) and health benefit plans, the major case law relating to ERISA and health plans, and the implications of the preemption of state regulations for health plan sponsors and participants. It also presents the latest data on the number of health plan participants in self-funded ERISA plans. Finally, it presents a summary of current legislative proposals that would attempt to amend ERISA. Under the framework ERISA established for employee benefit plans, the regulation of employment-based health benefit plans has evolved into a two-tiered system in which both federal and state laws play important roles. The Supreme Court has interpreted ERISA's "savings" and "deemer" clauses to mean that insured plans are subject to regulations directly at the federal level and indirectly at the state level, while self-funded plans are regulated exclusively at the federal level. The ERISA statute and the courts' interpretations of the Act have created a sharp controversy over how employee health benefit plans are provided and administered, with state regulators and consumer advocates on one side of the debate and plan sponsors (e.g., employers and unions) on the other. State regulators and consumer advocates tend to favor more regulation, and in many instances greater regulation at the state level, which they argue would provide more protections for consumers. However, employers and unions (or any plan sponsors) think ERISA preemption is very important to their ability to provide innovative and cost-effective health benefits for their employees, and assert that ERISA's present structure should be preserved. The U.S. General Accounting Office (GAO) found that 44 million individuals (39 percent of those in ERISA plans) were enrolled in self-funded ERISA plans in 1993, up from 39 million (33 percent of those in ERISA plans) in 1989. The Employee Benefit Research Institute (EBRI), using the same methodology as GAO with 1995 data, estimated that 48 million individuals (39 percent of those in ERISA plans) were enrolled in self-funded ERISA plans in 1995. When policymakers look to amend ERISA, they should consider whether the change to ERISA will produce a higher level of quality for consumers than is being provided under the present system and will continue to do so in the future. Policymakers must also decide whether quality of care is better enhanced by health plans' greater exposure to liability or by market forces. If policymakers decide that increased exposure to liability is the route to go, will consumers be able to enjoy any potential improvement in quality or will more individuals end up uninsured because of increased costs and not be able to get any care regardless of the quality?  相似文献

The Effects of Diversity on Small Work Group Processes and Performance   总被引:2,自引:0,他引:2  
Diversity is an increasingly important factor inorganizational life as organizations worldwide becomemore diverse in terms of the gender, race, ethnicity,age, national origin, and other personal characteristics of their members. The exact impact ofwithin-group diversity on small group processes andperformance is unclear. Sometimes the effect ofdiversity seems positive, at other times negative, andin other situations, there seems to be no effect at all.In this article, we suggest that these types of findingsmight be explained by using agroup-development model to examine theimpact of diversity on group processes and performance. Our modeluses concepts from Jackson et al.'s (1995), Milliken andMartins' (1996), and other models, as well as our ownconcepts, to show how diversity affects group development and performance. Among the conceptsincluded in the model are readily detectable personalattributes, underlying personal attributes, cognitiveparadigm dissimilarity, cognitive costs and rewards, diversity management skills, group behavioralintegration, and cognitive performance resources. In thepages that follow, we will explain each of thecomponents of the model and suggest specific hypotheses generated from the model.  相似文献

The congruence model is a framework used to analyze organizational strengths and weaknesses and pinpoint specific areas for improving effectiveness. This article provides an overview of organizations as open systems, with examples in the primary care arena. It explains and applies the congruence model in the context of primary care issues and functions, including methods by which the model can be used to diagnose organizational problems and generate solutions. Changes needed in primary care due to the managed care environment, and areas of potential problems and sensitivities requiring organizational changes to meet market and regulatory demands now placed on PCOs are examined.  相似文献

The handwritten medical record has been the method of choice for documenting health care data since the last millennium. Given this successful tenure, it would be natural to greet any new information system that purports to be an advancement with skepticism. Moreover, physicians as a group are hardly progressive. Yet health care is taking a giant leap and is finally accepting computerization. The advantages and drawbacks of computerized information systems have long been thoroughly tested in such diverse industries as the military, banking, and the airlines. It is difficult to imagine any of these industries in their modern form without an advanced information system.  相似文献

Composition-consistent tournament solutions and social choice functions   总被引:1,自引:1,他引:0  
This paper introduces a new axiom for choice in preference profiles and tournaments, called composition-consistency. A social choice function is composition-consistent if it is non-sensitive to the cloning of one or several outcomes. The key feature of the composition consistency property is an operation concept called multiple composition product of profiles. The paper provides a brief overview of some social choice functions studied in the literature. Concerning the tournament solutions, it is proved that the Top Cycle, the Slater and the Copeland solutions are not composition-consistent, whereas the Banks, Uncovered Set, TEQ, Minimal Covering Set are composition-consistent. Moreover, we define the composition-consistent hull of a solution as the smallest composition-consistent solution containing . The composition-consistent hulls of the Top cycle and Copeland solutions are specified, and we give some hints about the location of the hull of the Slater set. Concerning social choice functions, it is shown that Kemeny, Borda and Minimax social choice functions are not composition-consistent, whereas the Paretian one is composition-consistent. Moreover, we prove that the latter is the composition-consistent hull of the Borda and Minimax functions.  相似文献

Women in many countries of southern Africa do not have majority status or have only recently gained this right. Majority status grants individuals adult legal status and the right to bring matters to court, own and administer property, have legal custody of children, and contract for marriage. This article summarizes the legal status of women in Botswana, Lesotho, South Africa, Swaziland, Zambia, and Zimbabwe. Lack of majority status contributes to the ongoing risk of poverty for women and makes them overly dependent on men. Compounding the situation in these countries is the presence of a dual legal system. Improving the situation of women and their families involves targeting changes in the legal system, influencing implementation of laws, educating women about their rights, and giving women needed support to seek their legal rights. The legal status of women must be viewed in the context of historical changes in the economic, educational, political, and cultural developments of society.The research for this paper was conducted during her previous faculty affiliation with the University of Michigan, School of Social Work. Her research interests include the impact of social change on women and families, rural mental health services, and health and mental health linkages. She received her Ph.D. from Rutgers University and her M.S.W. from the Columbia University School of Social Work.Her research interests are gender, work and family, culture and power, social transformations in rural and peri-urban communities, critical education, women and community politics, history of women, family and kinship issues, and community-based program development and evaluation.

SupposeL(X) is the law of a positive random variableX, andZ is positive and independent ofX. Admissible solution pairs (L(X),L(Z)) are sought for the in-law equation $\hat X \cong X o Z$ °Z, where $L\left( {\hat X} \right)$ is a weighted law constructed fromL(X), and ° is a binary operation which in some sense is increasing. The class of weights includes length biasing of arbitrary order. When ° is addition and the weighting is ordinary length biasing, the class of admissibleL(X) comprises the positive infinitely divisible laws. Examples are given subsuming all known specific cases. Some extensions for general order of length-biasing are discussed.  相似文献
