This special issue explores how one particular regional organisation, the Economic Community of West African States (ECOWAS), has defined certain transnational issues as security threats and how it has addressed them. In this introductory article, we begin by providing an overview and analysis of some of the most important transnational security challenges facing West Africa. Specifically, we discuss some of the problems raised by cross-border insurgencies, health challenges, organised criminal activities, terrorism and environmental degradation. We then examine the different levels at which actors have responded to these challenges. The section ‘Security culture: shaping the Economic Community of West African States (ECOWAS) response?’ sets out our approach to thinking about the concept of security culture and asks whether it might be relevant to understanding how and why ECOWAS has focused on responding to certain transnational security challenges and not to others. The final section provides an overview of the other articles in this issue.  相似文献

In an era of continuous campaigning, elections are seldom won in the final weeks of the formal campaign period. The 2007 Australian federal election saw voters dispatch a Liberal Party and Nationals Coalition government that had presided over a buoyant economy, and return the Australian Labor Party from the electoral wilderness it had occupied since 1996. The explanation of this revival in Labor's stocks can be traced to the Wheat Board scandal, the unpopularity of the labour market deregulation, and to a series of other political tribulations that the fourth Howard Government faced during 2005 and 2006. Initially their impact was masked by the failure of Labor's parliamentary leadership. But when caucus elected Kevin Rudd and freed him to position Labor as offering fresh ideas and a safe pair of hands, Labor seized a lead in the opinion polls and retained it throughout 2007. Rudd's tactical leadership of his party proved critical. This article describes how the 2007 campaign unfolded and the pattern of events which saw a refashioned ALP win an eighteen‐seat lower house majority.  相似文献

Banking, interest intermediation and political power   总被引:1,自引:0,他引:1  
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

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

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.

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
