The assumption that candidates make a difference to electoral outcomes in British general elections is tested through a comparison of the 1983 and 1987 general elections. Incumbent's Constituency-specific Vote Change (ICVC) between the June 1983 and June 1987 British general elections is measured by subtracting the average regional vote change for the incumbent's party from the constituency vote change registered by the incumbent. Regression analysis finds ICVC to be most significantly influenced in both the Labour and Conservative parties by the incumbent's length of tenure, displayed especially in the higher ICVC registered by first-term incumbents than by more senior incumbents. Variables indicating the security or insecurity of the seat in electoral terms are significantly related to ICVC in the Conservative but not in the Labour case. The findings for Labour indicate ICVC to be greater where electoral security is greater. This finding might be explained by successful Conservative party concentration on constituencies in which Labour incumbents appear to be vulnerable.  相似文献

Natural resource management policies like the Pacific salmon harvest policy developed by New York State often did not anticipate the extent of social, economic, and ethical concerns that would be generated, largely because the agency concentrated on biological considerations. The number of concerned stakeholders grew in proportion to both the success and failure of the initial policy. Had all participants been equally willing to recognize both the successes and the failures, development of a revised policy through group negotiations may have been possible, resulting in a cooperative mode of decision making. Instead, institutional mechanisms based on legislated process were ultimately the approach chosen for policy revision.  相似文献

This study compared AIDS knowledge and attitudes in public high school students (N=167), incarcerated delinquents (N=166), and emotionally disturbed (SED) adolescents (N=151). The response measure was a 50-item Acquired Immunodeficiency Syndrome (AIDS) questionnaire that was previously used by Bell et al., in their 1991 study of learning disabled adolescents. Although AIDS knowledge was moderately high in all three groups, widespread misunderstandings about disease transmission and awareness of high-risk groups and practices were noted. Knowledge scores were significantly higher in the public school sample than in the SED adolescents; moreover, they tended to be slightly higher (p<0.10) than the delinquent group as well. Teenagers with the severest emotional problems were by far the least informed. Age and race were also predictive of AIDS knowledge. Other results showed that delinquents were more permissive in their attitudes about sex, more inclined to disdain safe sex practices, and more likely to feel threatened by high-risk groups as well as powerless to protect themselves against AIDS. Generally speaking, the findings extend the work of other investigators on the needs for AIDS education in adolescents. The need is especially urgent in delinquent and emotionally disturbed youth who may require a more comprehensive intervention because of their greater knowledge deficits, propensity for high-risk practices, and tendency to deny or underestimate their own vulnerability.Received Ph.D. in clinical psychology from the University of Utah in Salt Lake City.

Abstract: Policy analysts have frequently noted the gap between the intentions of policy makers and the effects of a program of change. This paper questions the ability of the implementation process to achieve the objectives of the federal Employment Equity Act. It argues that organizations under the act have not progressed towards employment equity, not because they have failed to implement the policy according to its legal provisions, but because the act itself is fundamentally flawed. While collecting statistics from the workplace may be useful in identifying discriminatory practices and problem areas and in identifying weaknesses in the evaluative and corrective mechanisms in the act, the reliance on data collection as the sole measure of effective implementation is highly simplistic. The usefulness of the data is compromised by the extent to which they actually reflect decreased discrimination. Furthermore, it is erroneous to suppose that employers of their accord will sanction themselves when statistics reveal an unrepresentative internal workforce. Sommaire: Les analystes de politiques ont souvent noté l'éart entre les intentions de ceux qui définissent les politiques, d'une part, et les effets d'un programme porteur de changement, d'autre part. Cet article met en cause la capacité des processus de mise en oeuvre à réaliser les objectifs de la loi fédérale sur l'équité en matière d'emploi. Selon l'article, les organismes soumis à la Loi n'ont pas fait de progres vers l'eAquité en matière d'emploi, et ce, non pas parce qu'ils ont manqué d'appliquer la politique conformément à ses clauses légales, mais plutôt parce que la loi elle-même a des lacunes fondamentales. Recueillir des données statistiques sur les lieux de travail est peut-êre utile lorsqu'il s'agit d'identifier les pratiques discriminatoires et les faiblesses des mécanismes d'évaluation et de correction prévues par la loi, mais il serait par trop simpliste de se fier aux données comme indicateur unique d'une mise en oeuvre réussie. L'utilité des données est relative dans la mesure oh elles reflètent simplement une diminution de la discrimination. De plus, il est incorrect de supposer que les employeurs se sanctionneront deux-mêmes lorsque les données statistiques révèlent l'inobservation de la loi.  相似文献

The recent report produced by Vice President Gore's committee on government efficiency highlights the importance of streamlining government operations. But often there are trade-offs between administrative streamlining and accomplishing substantive program objectives. This article examines these tradeoffs in the context of the Food Stamp Program, an important component of the United States' safety net for providing low-income assistance. We estimate impacts on both administrative costs and substantive outcomes (participant food expenditures) resulting from issuing program benefits in the form of checks rather than the usual food coupons. The findings, which are based on experimental tests of the cashout approach in parts of Alabama and California, suggest that significant cost savings can be attained through cashout but that these savings may be achieved at the cost of weakening the program's ability to achieve its substantive objective of encouraging food use.  相似文献

Despite a comparative disadvantage vis-à-vis whites in resources like education that often are considered to lead to political sophistication, African Americans show signs of being a rather politically sophisticated group of people. Given that better educated people are much more likely than those with less education to see larger differences between Democrats and Republicans, the propensity for blacks to perceive larger differences between the parties, both in general and on specific issues, is striking. This puzzle is explained by the fact that education has a huge impact on seeing partisan differences for whites, but not for blacks. That this understanding of the structure of American politics has so completely penetrated black public opinion is quite remarkable. Strength of partisanship, and to a lesser degree, racial consciousness, appear to be largely responsible for blacks (particularly less educated blacks) perceiving such stark party differences.  相似文献

Federalism is first examined as an ideal-type political orderas possibly emergent from initial constitutional agreement amongmembers of a prospective political community. This abstractedand nonhistorical analysis is followed by an examination ofthe possible applicability of the federalist ideal as the basisfor reform in specific historical-institutional settings. Thedirection of constitutional change toward effective federalismis discussed, with the devolution of political authority fromcentralized structures carefully distinguished from the limitedconcentration of authority from previously autonomous politicalunits.  相似文献
