Since its enactment in 1974, the Supplemental Security Income (SSI) program has had a stable caseload of about 4 million recipients. Hidden by this unchanging total is the fact that nearly 9 million persons were served by the program from 1974 to 1986. This study explores some SSI program dynamics by following a group of SSI awardees for a period of 4 years from the initial receipt of award in 1981. Many of these awardees had previous contact with the program either through a previous award or a denial. About 60 percent of the awardees were eligible at the end of the 4-year period. Most persons who became ineligible did so within the first 6 months after the award. 相似文献

In principle, reporting by state and local governments to thefederal government is essential to the design and implementationof national policy. In practice, reporting often engenders resentmentof federal intrusion and is often dismissed as a waste of stateand local resources. Is reporting useless? Does it strengthenthe federal government at the expense of state and local governments?We asked federal, state, local, and site officials about thevalue and burden of five specific reporting systems in elementaryand secondary education. Common assumptions about reportingdid not correspond to respondent reactions. Both value and burdencascade through the intergovernmental system, reaching policymakersin all governments. Although critics seldom discriminate betweentypes of reporting, we found that reporting designed to improvecompliance with federal standards evoked different judgmentsof value and burden than reporting designed for assistance.These results suggest some new approaches to federal policygoverning the collection of information and to the design ofindividual reporting systems. 相似文献

This article examines the ways in which a feminist family policy agenda has led to significant political action and change within American cities. Feminist groups, during the past fifteen years, became a part of emerging local women's rights policy networks that effected changes in several services for women and children: libraries (programming for women and non-sexist children's literature acquisitions policies); public education (gender equit under Title IX); social welfare (child care and displaced homemaker services); and criminal justice and health (the treatment of the victims of rape and domestic violence). This policy success stems not only from the workings of traditional interest group politics and policy networks but also from the astute use of political symbols, bureaucratic norms, and the federal system. 相似文献

We examine whether nations, faced with the threat of terrorism, will be motivated to engage in the efficient amount of retaliation against terrorists. We demonstrate that the problem confronting the efforts of nations to achieve an optimal retaliation against terrorists is understated by the traditional free-rider analysis. In particular, nations have the option of actually selling or reducing the public good of retaliation, provided through the efforts of others, by offering safe havens to terrorists in return for the terrorists' pledge to attack elsewhere. This paid-rider behavior is also shown to apply to other public good scenarios.The authors gratefully acknowledge the helpful comments of Gordon Tullock on an earlier draft. Sole responsibility for the paper's content rests with the authors. Todd Sandler's research was supported by a Science and Humanities Research Institute Summer Grant at Iowa State University. 相似文献

In order to assess the relationship between family members' cognitive and affective responses to nuclear war issues, 317 college students and their parents (n=559) independently completed a multifaceted questionnaire that included items concerning personal reactions, predictions, opinions, and attitudes about nuclear war. Results revealed a negligible relationship between the responses of college students and their parents, although the level of concordance between mothers and fathers was somewhat greater. Moreover, parents and students were relatively poor at predicting each others' nuclear threat attitudes, and the strength with which an attitude was endorsed did not enhance its predictability. Results are discussed with regard to heterogeneity in attitudinal and affective reactions within families, and with regard to the idea that infrequent communication concerning nuclear war issues may be occurring.Portions of this article were presented at the meeting of the American Psychological Association, Los Angeles, California, August 25, 1985.Interested in clinical and counseling psychology, the psychological effects of the threat of nuclear war, and parent training.Interested in counseling psychology, nuclear war issues, and the concept-specific measurement of emotionality.Interested in counseling psychology, nuclear war issues, and factors influencing custody decisions. 相似文献

Sexual decision making, perceptions of responsibility for birth control and pregnancy, and knowledge of contraception and the consequences of teenage pregnancy were assessed among 251 high-risk seventh- and eighth-grade black, inner-city adolescents to determine these young peoples' need for information. Survey results indicated that these adolescents were aware of contraceptive methods, but lacked practical information about requirements for obtaining them or method effectiveness. Many students were uninformed about the circumstances under which pregnancy can occur. Males indicated a willingness to have intercourse, regardless of the contraceptives used, if any, and believed responsibility for use of a birth control method belonged to females. Females believed themselves to be responsible for contraceptive utilization and preferred intercourse with adequate protection. Both genders endorsed the notion of mutual responsibility for an unplanned pregnancy and related decisions. Implications for school-based family life education programs for young adolescents are discussed.This research was supported by grants from the Illinois Department of Children and Family Services and the Pittway Charitable Trust, to the Center for Health Services and Policy Research of Northwestern University; the project was administered by the Ounce of Prevention Fund. Portions of this paper were presented at the 112th annual meeting of the American Public Health Association at Anaheim, California, November 1984.
