The aim of the present study was to examine a model positing that association with deviant peers mediates the relation between adolescent perceived parenting behaviors (maternal monitoring and involvement), the interaction of these parenting behaviors, and delinquency in a sample of 135 urban African American adolescents (13–19 years of age). Regression analyses revealed a monitoring by involvement interaction among African American females, suggesting that maternal monitoring may effectively reduce delinquency among African American female adolescents, and that this reduction may be enhanced by increased maternal involvement. Among African American males, only the relation between association with deviant peers and delinquency was supported, suggesting that maternal parenting behaviors may, in isolation, be insufficient in the prevention of delinquent behaviors in African American male adolescents. The results suggest that the pathways from parenting to association with deviant peers and delinquency may differ in males and females, and the salience of certain parenting behaviors may differ across gender.

In 2001 the UK Government's Department for International Development (DFID) launched a new way of conducting political economy analysis, called ‘Drivers of Change’ (DoC). DoC is now well known amongst international development practitioners and professionals. This article provides an introduction to DoC, explaining what it is, where DoC analysis has taken place and which organisations have been involved. It also explores the history and background to DoC, outlines its effect on other bi and multi‐lateral donors and shows how the approach has evolved over the last 5 years. The final section of the article analyses some of the current limitations in the way DoC analysis is used by DFID and predicts how the approach may develop in the future.

Abstract: Senior officials in the federal public service are giving new attention to the need to strengthen policy capacity and this article draws heavily on the work of a task force of federal officials. Four themes run through the article: there is a strong, but neglected, managerial dimension to policy work; the greatest weakness in the current system is dealing with longer-term and strategic issues, especially of a horizontal nature; policy managers need to pay more attention to how to work with and support the external policy community; leadership at the most senior levels of the public service is critical for strengthening policy capacity. Policy management within departments is examined in terms of seven broad policy functions and organizational arrangements. Policy management across government is examined in terms of the role of central agencies and the special problems of horizontal coordination, including the conditions promoting coordination and the machinery of interdepartmental relations. The importance of the personnel dimension of policy work is underlined, with consideration of policy generalists, policy managers and policy specialists. Finally, relations with the policy research community and the provinces are examined. Sommaire: Les dirigeants de la Fonction publique fédérale s'intéressent davantage maintenant à la nécessité de renforcer la capacité d'élaboration des politiques, et le présent article s'appuie largement sur les travaux d'un groupe de travail composé de fonctionnaires. L'article illustre quatre thèmes: le travail d'élaboration de politiques comporte un aspect de gestion très marqué, mais négligé; la plus grande faiblesse du système actuel réside dans sa façon d'aborder les questions stratégiques et à long terme, surtout celles de nature horizontale; il faut que les administrateurs de politiques cherchent davantage à collaborer avec les organes délibérants extérieurs et à leur fournir leur appui; il incombe aux plus hauts dirigeants de la Fonction publique d'avoir le leadership si Ton veut renforcer la capacité d'élaboration de politiques. On examine la gestion des politiques dans les ministères par rapport à sept grandes fonctions des politiques et aux arrangements organisationnels. On étudie la gestion des politiques dans tout le gouvernement en fonction du rôle des organismes centraux et des problèmes particuliers de la coordination horizontale, notamment les conditions favorables à la coordination et le mécanisme des relations interministérielles. On souligne l'importance de l'aspect personnel dans le travail d'élaboration et on mentionne les généralistes, les administrateurs et les spécialistes des politiques. On aborde pour finir les relations avec le milieu de la recherche sur les politiques et avec les provinces.  相似文献

Abstract: Australian small business enterprises, operated as exempt proprietary companies, are exposed to numerous statutory requirements. The Corporations Law Simplification Taskforce has proposed a number of changes with the stated objective of minimising the statutory burdens faced by small business. One of the recommendations of the taskforce is that most exempt proprietary companies be exempted from the requirement to supply key financial data in annual returns lodged with the Australian Securities Commission. This paper provides a review of the existing statutory responsibility for exempt proprietary companies to prepare annual returns including key financial data and lodge them with the ASC. A common justification offered for the introduction and continued maintenance of annual reporting requirements has been the protection of the public interest. The “public choice” theory of regulation provides alternative explanations for the regulation, including the promotion of producer interests or the promotion of the interests of the regulatory agency responsible for the administration of the legislation, the Australian Securities Commission, and other government departments such as Attorney-General's, Finance and Treasury. The existence of alternative explanations raises the possibility that the regulation is not motivated exclusively by the public interest. Indirect evidence of the usefulness of the annual reporting requirements was gathered with a consideration of the quality of the key financial data disclosed in annual returns. More than 40% of the annual returns lodged by a sample of exempt proprietary companies, during the years 1986 to 1989, contained key financial data which was inconsistent with being extracted from a properly prepared balance sheet (where assets minus liabilities equal shareholders' equity). The possibility that the maintenance of annual reporting requirements is not in the public interest, and the limited reliability of key financial data disclosures made, offers some support for the recent recommendations of the Corporations Law Simplification Taskforce that annual reporting requirements for small business enterprises be modified.  相似文献

This paper considers the notion of cycle avoiding trajectories in majority voting tournaments and shows that they underlie and guide several apparently disparate voting processes. The set of alternatives that are maximal with respect to such trajectories constitutes a new solution set of considerable significance. It may be dubbed the Banks set, in recognition of the important paper by Banks (1985) that first made use of this set. The purpose of this paper is to informally demonstrate that the Banks set is a solution set of broad relevance for understanding group decision making in both cooperative and non-cooperative settings and under both sincere and sophisticated voting. In addition, we show how sincere and sophisticated voting processes can be viewed as mirror images of one another — embodying respectively, “dmemory” and “foresight.” We also show how to develop the idea of a “sophisticated agenda,” one in which the choice of what alternatives to propose is itself a matter of strategic calculation.  相似文献

In order to receive payments under the Supplemental Security Income (SSI) program, an aged, blind, or disabled person's countable resources must fall below specified limits. The current limits are +2,000 for an individual and +3,000 for a couple. In 1987, when the data were collected for this study, these limits were +1,800 for an individual and +2,700 for a couple. This study found that the resource levels of most SSI recipients were well below the 1987 limits. A majority of SSI recipients had less than +100 in countable resources, and only about 12 percent of SSI recipients had more than +1,000 of resources. These low levels of resources ensure that relatively few recipients become ineligible for SSI payments because of resource accumulation. The most common forms of countable resources held by SSI recipients were cash, checking accounts, and savings accounts.  相似文献

Since its enactment in 1974, the Supplemental Security Income (SSI) program has had a stable caseload of about 4 million recipients. Hidden by this unchanging total is the fact that nearly 9 million persons were served by the program from 1974 to 1986. This study explores some SSI program dynamics by following a group of SSI awardees for a period of 4 years from the initial receipt of award in 1981. Many of these awardees had previous contact with the program either through a previous award or a denial. About 60 percent of the awardees were eligible at the end of the 4-year period. Most persons who became ineligible did so within the first 6 months after the award.  相似文献
