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. Conclusions or opinions expressed in this article are those of the authors and do not necessarily reflect the views of the Center for Population Options, Northwestern University, or the State University of New York at Buffalo.Received Ph.D. from Loyola University of Chicago.

Abstract. The paper examines public opinion about the political involvement of trade unions in the UK and Denmark. Both are systems in which trade unions are linked to a political party and both have high rates of union density. However, whereas British unions have contested governments of both parties and opposed regulation of industrial relations, Danish unions have a tradition of cooperation with government and are entangled in a web of institutionalized industrial relations. Results, however, are amazingly similar. Both the public at large and union members accept unions in general and also their political involvement, but oppose contestation of political authority. Irrespective of union behaviour, beliefs in the supremacy of parliament seems to be firmly rooted in public opinion.  相似文献

Abstract: There is an ambivalence in attitudes to public administration as a field of study among both academics and practitioners in Australia. Teachers, researchers, students, public servants seeking training and managers have differing interests and expectations. Disagreements about the field have contributed to the lack of a unified framework of concepts, while the field has fragmented into public administration, public policy and public management, aside from other divisions such as "old" versus "new" public administration. "Education" and "training" have taken diverging paths and academics and practitioners have drifted apart. There needs to be a closer dialogue that can only be based on a generally agreed paradigm for Australian Public Administration as a field of study.  相似文献

In the economic analysis of the theory of government, two views of government are evident. The Pigovian view sees government as a benevolent actor striving to correct for the inadequacies and excesses of an unrestrained marketplace. The ‘Public Choice’ view of government portrays government as the tool of special interest groups as likely to generate distortions as to correct them. In this paper, a model of government that incorporates both views will be developed and then empirically tested. The model developed assumes that all expenditures by the government are inputs into the private sector production. Treating government expenditures as inputs into the production of private sector output, there is some optimal size of government that maximizes private sector output. The model incorporates a general production function for private sector output. Output is a function of private labor, private capital, and government expenditures. The Pigovian and Public Choice views of government are reflected in the assumed impact of G on the marginal productivities of L and K. The model is tested using United States data and a Cobb-Douglas production function. Estimates indicate that the 1983 level of government expenditures exceeds by 87 percent the level that would maximize private sector output. Reducing government from $ 491 billion to $ 263 billion and shifting the freed labor to the private sector would increase output from $ 1187 billion to $ 1451 billion.  相似文献

This paper is an analysis of two rational choice theories of elections. Anthony Downs and Stanley Kelley's theories yield complementary interpretations of the 1984 U. S. election. Reagan's victory was based on both prospective and retrospective judgments as well as on candidate and policy considerations. Reagan won that element of an incumbent's reelection that is a referendum on his performance as president. However, people also voted on the basis of domestic and foreign policy preferences for the second term. On these issues voters preferred Mondale as much as Reagan. Reagan's victory owed remarkably little to his conservative agenda and to a warm regard for his personal qualities as a leader. His landslide was deceptive. The two Reagan victories were among the weakest of the six landslides of the postwar period by Kelley's test of decisiveness. The Reagan elections have not set the United States on the course of a long-term conservative agenda in either domestic or foreign affairs.  相似文献

The 84.3 million workers protected by workers' compensation laws in 1985 represented 87 percent of all wage and salary workers in that year. Both the amount of benefits paid to workers and the cost of the program to employers rose substantially from 1984 to 1985. Benefit payments totaled $22.5 billion-14.1 percent higher than in 1984 and the largest annual increase since 1978-79. About two-thirds of the payments in 1985 were money payments ($15.1 billion) and the remainder ($7.4 billion) went for medical care for disabled workers. Private insurance companies made nearly three-fifths of these payments and State funds and self-insured employers each paid about one-fifth of the total benefit amount in 1985. For the first time since 1978, the annual growth in employer costs exceeded the growth in workers' benefits, resulting in a slight decrease in the loss ratio for 1984-85. Employer costs were up nearly 17 percent from the previous year, reaching an estimated $29.3 billion. Covered payrolls increased by 7 percent in that same period. Total benefit payments as a percent of payroll also increased noticeably in 1985.  相似文献
