Abstract. Two theoretical traditions in the study of European voter alignments emphasize alternatively class and territorial structuring of mass politics. Until the 1970's the developmental paradigm resting on the class-based, stable polity model of the 1945–1970 period ruled the research agenda. The weakening of party alignments in the 1970's and the introduction of the competing territorial paradigm challenged the dominant model. This research tests both models in Britain against the supposed stability of the 1945–1970 period. The results demonstrate that while the developmental model fits Britain as a whole quite well, the introduction of regional polity analysis exposes considerable instability of voter and party alignments, uneven class development and the mobilization of cultural cleavages, dynamics which undergird the politics of cultural defence and find expression in the nationalist parties in the 1970's. In questioning the assumed stability of the 1945–1970 period the findings challenge the foundations of the current debates on realignment in Britain.  相似文献

The Cayman Islands use some of the increasingly familiar methods of resolving administratively the problems of smallness. The country's development and administrative performance depend on human resources which need to be planned in order to reduce dependence on outsiders, especially among the middle ranks of technical and professional staff. Education and training for the public service in the Cayman Islands is inadequate. Control of the administration is weak, especially among the independent boards and commissions, and there is a need for appeal procedures when the principles of natural justice have been breached. Political manipultion in personnel matters adversely affects performance, and there is a need for an effective civil service association to deal with other abuses. The problems of public administration are solved by scaling down the role of government in favour of private enterprise and against the provision of social welfare.  相似文献

Theoreticians claim that negotiated compensation plans could overcome local resistance to nuclear waste (or other less than desirable) facilities, and the Nuclear Waste Policy Act of 1982 gives the Department of Energy considerable flexibility to negotiate with and compensate states in which it locates waste storage. DOE's monitored retrievable storage (MRS) proposal is the first attempt under the NWPA to site nuclear waste operations, and both DOE and one local community tried the negotiated compensation approach with some success. State and regional leaders chose to oppose the project rather than to negotiate, however. The limited experience to date suggests that local reluctance to negotiate is a generic weakness of the compensation approach to siting and must be given greater attention.  相似文献

Given the high incidence of obesity and obesity-related health problems among low-income African American women, it is both timely and significant to study factors that contribute to obesity in this population. The perception of current body size (body image) and desired body size (body image ideal) has been associated with the development of anorexia and bulimia in white adolescent girls. Body images and ideals may also be related to the development of obesity among African Americans adolescent girls. This study examined the body images and ideals of 27 low-income African American mothers and their 29 preadolescent daughters. Results suggest that there is a relationship between mothers' perceptions of their daughters bodies and their daughters' body images. Preadolescent, low-income, African American girls have normal weight ideals rather than the ultrathin ideals typically found among white girls. Normal weight girls have ideals that are heavier than their body images. This population may be less motivated than those with thinner ideals to engage in behaviors that would prevent the development of obesity during adolescence. Health promotion programs for this population should acknowledge cultural body weight standards.This study was funded by the American Heart Association of Metropolitan Chicago.Received B.A from the University of Pennsylvania. Research interests include cross-cultural studies of body image, eating disorders, health risk perceptions, and health promotion programs.Received Ph.D. from in Clinical Psychology from Long Island University. Research interests include obesity prevention, binge eating, and cultural differences in eating behavior.  相似文献

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. Current research interests include parent-adolescent relationships, adolescent peer relations, and adolescent sexuality.Received Ph.D. from Rutgers, The State University of New Jersey.

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

Third World cities are characterized by weak administrative and managerial capacity for environmental planning. Benin City, Nigeria, is no exception. Benin's environmental problems result largely from its unplanned land use and weak development control. These problems include lack of open space, substandard housing and an increasing volume of refuse. The administrative arrangements to handle environmental problems include the Town Planning Division, which enforces building and housing codes and land use regulations; and the Task Force on Environmental Sanitation, responsible for solid waste management. However, these arrangements have not produced satisfactory results. Failure has been due partly to the ad hoc organization of environmental administration; the overlapping perception of environmental problems; the alienation of the public; dispersal of authority; and the scale of jurisdictional units. Effective environmental planning administration must adopt a holistic approach, which recognizes the need for a comprehensive environmental planning and a concentration of environmental authority. This is based on the premise that environmental issues are the responsibility of one agency but an obligation for all. Structurally, the concentration of environmental authority hinges on the principle of cooperative leadership by the Federal Government. This calls urgently for the establishment of a Federal Environmental Protection Agency at the centre, and Environmental Management Boards at state levels. The Boards would provide an administrative umbrella under which the management of various aspects of the environment are coordinated. In order to maximize the cooperation of the public, the traditional power structure of the Oba (paramount chiefs and community leaders) must be involved in the conception and implementation of environmental planning. Citizen participation would in turn be maximized if the neighbourhood is adopted as the jurisdictional unit, upon which environmental administration and management are systematically built.  相似文献

Three phases of development of the subject of evaluation are identified. Up to 1979 it was still in its infancy, with the main impetus coming from the USA (the World Bank and US AID), and from one or two large UN organizations, although the OECD also did some useful work in bringing evaluators together. The second phase (1979-1984) saw rapid ‘take-off’, with greatly increased resources going into evaluation work, and a veritable ‘explosion’ of interest worldwide. All the main donors had by now set up evaluation units and were amassing enough material to begin to ‘synthesize’ the findings. The OECD provided a focus and a forum through its Expert Group on Aid Evaluation. The third phase, from 1984 onwards, finds the subject having ‘come of age’, its maturity being marked by the publication of major works such as Cassen's Does Aid Work?. The emphasis now is switching from ex-post evaluation towards improving project design through such techniques as the logical framework.  相似文献
