This paper considers the division of a public budget among competing interests. The planner determines the optimal allocation by maximizing a weighted social welfare function. These weights reflect society's attitudes to different recipient groups, and are not constrained to be constant. By exerting “pressure”, the recipients can attempt to manipulate the weights and hence influence the division of the budget. The amount of resources used on pressure, and the effects on the preference weights are calculated. An important parameter in the model is the elasticity of pressure, for which an appropriate estimate is presented from the case of competition for a share of a health services budget in Norway. 相似文献

Models of prototyped and non-prototyped competitions for prime contracts from the U.S. defense department suggest that the latter are much more vulnerable to bid-rigging than are the former. Subcontracting data reveal that pairs of firms who have been rivals in major non-prototyped competitions have a larger number of subcontracts with one another than do other pairs of firms. The analysis concludes that subcontracts may serve as vehicles for division of the spoils of collusive bidding on prime contracts. 相似文献

Abstract In several recent studies George Rabinowitz and his co–authors challenge the 'classical' spatial model of issue voting, the proximity model, by introducing a directional model. In this article we examine whether different measurement of perceived issue positions of candidates or parties leads to diverging judgments about the predictive power of the directional model (which is claimed to be empirically superior), as compared to the proximity model, using data from the USA and Germany. The results demonstrate that the measurement preferred by Rabinowitz et al. tends to bias empirical findings in favour of directional theory. If we use a more plausible operational definition of issue positions of candidates and parties the directional model in both countries fails to turn out superior. 相似文献

This article examines different explanations for the cross–national diffusion of three recent innovations in bureaucratic accountability—the institution of the ombudsman, freedom of information legislation and data protection (information privacy) law. The first two explanations are based on the assumption that these innovations are by–products of modernization, either the growth of the state or democratization. The third assumes that policy is shaped through processes of international communication. A combination of methodologies is employed to conclude that while the growth of government and liberal democratic values are necessary conditions for the adoption of all three policy instruments, they are not sufficient conditions. The pattern of adoption observed is best explained by examining how evidence about these respective policies flows from adopting states to non–adopters. In the case of the ombudsman, this process can be characterized as one of lesson–drawing; for freedom of information, evidence is used for legitimation purposes; for data protection, the diffusion is attributable to harmonization through international organizations. Policy transfer is hence a multi–faceted concept that embraces a number of distinct processes of transnational learning and communication. 相似文献

First- and second-year findings from a study of the development of disordered eating in pre- and early adolescents are presented. Fifth- and sixth-grade girls (n = 80) and boys (n = 85) were assessed on depression, body image, self-esteem, and eating behaviors and attitudes in Year 1 and again one year later. Weight, height, and pubertal development were also evaluated in Year 1 and Year 2. Gender differences existed on all measures in Year 2 and indicated consistently poorer scores for girls compared to boys. For girls, Year 1 Body Mass Index and pubertal development predicted Year 2 disordered eating. For boys, poor body image in Year 1 predicted Year 2 disordered eating. The importance of identifying early risk factors for eating disorders is discussed. 相似文献

In this study, the most salient worries of Dutch adolescents are examined and the most often reported symptoms are ranked. The relationship between worrying and health is explored using structural modeling as are the frequently found gender differences in these areas. Worrying is postulated as an indicator of psychosocial well-being along with affectivity, ease of parental communications, tiredness, and loneliness. Health, or physiological status, is indicated by reported symptoms, frequency of doctors visits, aspirin consumption, and a global health measure. Four hundred and sixteen high-school students (211 girls and 205 boys) fitted in a questionnaire during school hours. The structure of the bet fitting model was the same for boys and girls, indicating that gender differences are a question of degree, and not of different structural relationships. Psychosocial well-being explained 77% of the variance in physiological status. The implications of the findings for health education are discussed. 相似文献

Church attendance,meaningfulness of religion,and depressive symptomatology among adolescents 总被引:1,自引:0,他引:1

Self-administered questionnaires were completed by 451 adolescents at a public high school in Texas during the spring semester 1989. The instrument used contained the Beck Depression Inventory (BDI) and items to determine participants' gender, frequency of church attendance, and meaningfulness of one's religion. Based on social support research and the writings of Carl Jung and Viktor Frankl, it was predicted that those who attended church frequently and those who viewed their religions as providing meaning for their lives would have lower BDI scores than their classmates. The findings supported these predictions. Implications and a discussion of the results are included.Received Ed.D. in educational psychology from University of Illinois.
