Banking, interest intermediation and political power 总被引:1,自引:0,他引:1
WILLIAM D. COLEMAN 《European Journal of Political Research》1994,26(1):31-58
Abstract. This article seeks to introduce the concept of political power more explicitly into the discussion of the organizational attributes of societal interests. In pursuit of this objective, it defines a set of empirical indicators of the organisational conditions of interest intermediation systems that enhance the exercise of political power. The indicators are illustrated through a comparative study of the banking sector at the European Community level and in five countries: Canada, France, Germany, the United Kingdom, and the United States. The comparison of the banking sector interest intermediation systems shows that the power of banks in Germany rests not only on their equity participation in large industrial concerns, but also on a highly developed interest intermediation system, the most integrated of the five countries. The analysis demonstrates from still another perspective the close imbrication of the state and finance in France. Finally; the article demonstrates the deep fragmentation of the US associational system, a system that has acted as a serious obstacle to banking system reform in America. 相似文献

Abstract: Traditionally public policy analysis has been able to employ the conceptual framework offered by the theory of market failure in order to evaluate the efficiency of market outcomes. However, until fairly recently, no corresponding analytical structure existed which could facilitate the examination of the efficiency and equity characteristics of government or non-market outcomes. Quite apart from public choice theory, an embryonic normative theory of government failure has now been developed which can act as a conceptual analogue to the market failure paradigm. At present, three theories of government failure coexist in the literature: Wolf's theory of non-market failure; Le Grand's theory of government failure; and Vining and Weimer's theory of govern- ment production failure. These models form the basis for a more universal theory of government failure. Nevertheless, in its current state of development this seminal literature can still assist in rational public policy design subject to certain caveats. Foremost amongst these is the need for policy analysts to augment the efficiency and equity criteria with some additional broader normative measures, and the necessity for care to be taken in the use of allocative efficiency as a benchmark in non-market circumstances. 相似文献

This article investigates the use of market incentives to encourage household waste recycling by pricing waste-disposal services according to the quantity of waste generated. We use a natural experiment from an upstate New York county to examine how quantity-based pricing of waste disposal affects reported household recycling behavior, when used by itself or in conjunction with curbside pickup of recyclables or mandatory recycling laws. Curbside pickup was found to have the greatest effect on reported recycling behavior, although higher waste-disposal prices might alter these conclusions. Other concerns about quantity-based pricing of solid waste—distributional effects, public acceptance, and adverse incentives—are also examined. 相似文献

Abstract: Achieving employment equity has become an important organizational goal. An important part of an Employment Equity Program (EEP) is to inform designated group members (i.e., women, members of visible minorities, disabled persons and aboriginal peoples) that career opportunities are available to them. Public awareness programs that provide this information, such as publicity campaigns and visits to schools and community centres, are infrequently used, however. The research reported in this article demonstrates that public awareness programs can be used to encourage designated group members to apply for jobs that are traditionally avoided. In this study, young women demonstrated a greater interest in and intention to choose non-traditional careers after participating in a public awareness program (an information session) about one specific non-traditional career (police officer). Implications of this research for recruiting and employment equity initiatives are discussed. Sommaire: L'éuité en matière d'emploi est l'une des principales préoccupations des organisations. 1 cet effet, les programmes d'équité en matière d'emploi (PEME) visent à corriger la discrimination dans l'emploi à 1'égard des groupes défavorisés (femmes, minorités visibles, handicapés et autochtones). Les programmes d'information publique offrant une telle information, par le biais de campagnes d'information, de visites scolaires et dans les centres communautaires, sont cependant peu utilisés. Dans cet article, les réultats de notre recherche démontrent que les programmes d'information publique peuvent encourager les membres des groupes défavorisés à soumettre leur candidature dans les secteurs d'emploi non-traditionnels. Dans cette étude, des jeunes femmes ont montré un intérêt plus prononcéà choisir une carrière non-traditionnelle après avoir participéà un programme d'information publique (une séance d'information sur la carrière d'officier de police). Pour terminer, nous discutons les implications de cette recherche sur le recrutement ainsi que les programmes sur l'équité en matière d'emploi. 相似文献

Adolescents' perceptions of their attachment relationships with their mothers,fathers, and friends 总被引:1,自引:0,他引:1
This study explored changes in New Zealand adolescents' perceptions of their attachment relationships with their mothers, fathers, and friends. The main findings revealed that from early to late adolescence: Males and females remained stable in their quality of affect toward their mothers. With increasing age, females utilized their mothers for support and proximity more, whereas males utilized their mothers for support and proximity less. With increasing age, males and females rated their quality of affect toward their fathers as lower and utilized their fathers for support and proximity less. Females had a higher quality of affect toward friends than males regardless of age, but both males and females increased their utilization of friends for support and proximity over age. Further analyses revealed that Pacific Island adolescents utilized their mothers less for support and proximity than European/Pakeha adolescents. Adolescents from one-parent families utilized their fathers less for support and proximity and had a lower quality of affect toward him than adolescents from two-parent families. These findings suggested that substantial changes take place in attachment relationships from early to late adolescence and highlighted the need for research to differentiate between the sex of adolescent and sex of parent dyads in order to examine adolescents' affective relationships effectively.This research is based on the first author's doctoral dissertation at the University of Auckland.Received Ph.D. from the University of Auckland.

The purpose of this study was to test hypotheses regarding (1) relations among negative affect and hormones of gonadal and adrenal origin in young adolescents, at three times of measurement, over a one-year period; and (2) stability of negative affect. The sample consisted of 10- to 14-year-old boys (N=56) and 9- to 14-year-old girls (N=52). The adolescents were assessed three times at 6-month intervals over one year. Serum levels of gonadotropins, gonadal steroids, adrenal androgens, and cortisol were assessed, as well as stage of pubertal development (Tanner criteria). The negative affect assessments consisted of self-report questionnaire and interview measures of anxiety and depressive affect, as well as mother reports of internalizing behavior problems. In the concurrent (cross-sectional) analyses, boys reporting higher levels of negative affect tended to be those at higher genital stage or older age, with lower testosterone and cortisol levels and lower dehydroepian-drosterone sulphate levels. In the longitudinal analyses, negative affect, and to a lesser extent hormone levels at the first time of measurement predicted negative affect 12 months later. The findings suggest that puberty-related hormone levels should be considered along with psychological characteristics in examining the processes involved in the development of negative affect during the pubertal years.Received Ph.D. from The Pennsylvania State University.

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.

The policy movement is unified by a common interest in the improvement of policy decisions through scientific inquiry. The movement is differentiated, however, because this common interest is highly ambiguous and subject to interpretation from different perspectives. This paper applies a policy sciences perspective to the movement's disappointments over the last few decades, and in particular, the failure to realize earlier aspirations for rational, objective analysis on the more important and controversial policy issues. The paper offers a definition and diagnosis of the underlying problem, and suggests what can be done about it as a matter of individual and collective choice. 相似文献
