The current study examined the nature and style of mother-adolescent conversations, how these conversations differ by subject matter, and dyadic and individual differences. Thirty-one mother-adolescent dyads (17 boys, 14 girls) with a child between the ages of 11 and 14 had a nonstructured conversation, and conversations about conflict and sexuality. They also completed questionnaires on beliefs about acquired immunodeficiency syndrome (AIDS). Conversations were measured for turn taking, total number of words, and conversational dominance, as well as nonverbal measures of affiliation, shame, and contempt. Conversations about sexuality involved less turn taking, fewer words, and more mother dominance than nonstructured conversations. Conversations about conflicts involved less turn taking but more words than nonstructured conversations. Some gender and age differences were found. More interactive conflict conversations contained higher levels of affiliation, and lower levels of child shame than conversations with fewer turns or higher mother dominance. In addition, children in more interactive dyads possessed a larger percentage of their mother's AIDS knowledge, and worried about AIDS a moderate amount.This research was supported by National Institutes of Child Health and Human Development Grant No. HD27035.Received M.A. from UCLA.

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

Under the Burger Court, the constitutional relationship betweenstates and their municipalities has been examined primarilyin cases involving private suits initiated against municipalitiesunder federal antitrust and civil rights statutes. Since theCourt's 1943 Parker v. Brown decision, it had been presumedthat municipalities as political subdivisions of states wereas immune as their states from tort liability under the ShermanAntitrust Act. The Burger Court, however, ruled that municipalitiesare not automatically immunized from tort liability simply becauseof their status as political subdivisions unless they can demonstratethat their actions were undertaken pursuant to an expressedstate policy. After 1980, the Court continued to uphold thevulnerability of municipalities to private suits authorizedby federal statutes, but moved to narrow the types of remedyappropriate under common law. The Burger Court did not, therefore,address the more fundamental question of whether municipalitiesas public actors should be liable to private damages in thecourse of their public functions. 相似文献

It is argued that there are significant differences between green electoral politics in Europe and green developments in the affluent non-European west, and that these are such that, despite the greater political formalization of the green movement in Western Europe, there is a sense in which North American and Antipodean developments are ultimately more fundamental than those that have occurred in Europe. Loosely adopting explanatory categories employed by Rudig and Lowe in a Political Studies article, we examine evidence under four sub-heads: electoral thresholds; the historical legacy of the environment movement; the different contextual roles played by the anti-nuclear movement and wilderness experience, and ecology, Marxism and the new left. 相似文献

Electronic monitoring is a recent advance in information gathering for correctional program administration. To be effective in achieving correctional goals, electronic monitors must be applied to offenders when there is some risk of performance problem. Advocates of electronic monitoring argue they can promote public safety, save tax dollars, and enhance correctional performance. Because corrections systems find it so difficult to innovate with offenders who represent a risk to society, these claims are overstated. Electronic monitoring raises short-term concerns concerning damage to correctional program credibility and long-term concerns about the enhancement of social control. 相似文献

Abstract: In the 1970s, both Australia and the United States instituted legal reforms aimed at promoting greater accountability among public servants. Prompted by growing awareness of the need to encourage and protect federal government whistleblowers, Congress enacted whistleblower protection measures in the Civil Service Reform Act of 1978. Although the notion of open government in Australia has never been extended to include whistleblowing by public servants, probing the issue of whether or not United States whistleblower protection can serve as a reform model in the search for more effective legal mechanisms for ensuring government accountability can provide lessons and insights of value to Australian public administrators. Analysis of the role and impact of the Office of the Special Counsel and the Merit Systems Protection Board as established under the Civil Service Reform Act reveals many difficulties associated with whistleblower protection. Research has substantiated the jurisdictional ambiguities, administrative and procedural deficiencies and lack of sanctioning power which plague this reform effort. Similar deficiencies also impede the protection of parliamentary witnesses in Australia. Evaluation of whistleblower protection leads to the conclusion that reform models in either country for ensuring government accountability must not be judged solely through examination of statutory provisions. There must also be in place strong stabilising factors such as political unity, economic comfort, social discipline, civic virtue and public service ideology in order to achieve the common public service goal of rendering governmental decision-making more accountable to persons affected by it and open to review by independent decision makers. 相似文献
