We develop a model to understand the incidence of presidential and parliamentary institutions. Our analysis is predicated on two ideas: first, that minorities are relatively powerful in a parliamentary system compared to a presidential system, and second, that presidents have more power with respect to their own coalition than prime ministers do. These assumptions imply that while presidentialism has separation of powers, it does not necessarily have more checks and balances than parliamentarism. We show that political leaders who prefer presidentialism may be supported by their own coalition if they fear losing agenda‐setting power to another group. We argue that the model is consistent with a great deal of qualitative information about presidentialism in Africa and Latin America. (JEL: D72, P5, O1) 相似文献

While de-institutionalisation set out with the laudable aim to improve the quality of life of people with disability, the untethering of accommodation from support services has in some cases led to less than desirable outcomes. Poor regulation of for-profit boarding houses licensed to care for people with disability has led to the exploitation and abuse of some of Australia’s most vulnerable and marginalised people. Recognition of this, and a number of other factors, has led to the closure of many of New South Wales’ licensed boarding houses. This research presents the experiences of 15 former residents of licensed boarding houses and their supporters spanning from their time as a resident, the transition to other accommodation and their quality of life post transition. While finding the transition challenging, almost all of the former residents identified improvements in their lives since leaving the boarding house. 相似文献

An essential issue for laboratory experiments to inform policy debates is the “external validity” of the experimental results; that is, does behavior in the laboratory apply to behavior that occurs in the naturally occurring world? We examine this issue of external validity in the specific context of laboratory experiments on tax compliance, using two different types of evidence. We find that the behavioral patterns of subjects in the laboratory conform to those of individuals making a similar decision in naturally occurring settings. We also find that the behavioral responses of students are largely the same as those of nonstudents in identical experiments (JEL C9, H0, H3) 相似文献

Numerous professional fields have an increasing need for individuals trained in statistics and other quantitative analysis techniques. Today there exists great potential to fulfill this need by providing opportunities through online learning. However, to provide a high-quality education for returning adult professionals seeking advanced degrees in applied statistics online, many challenges need to be overcome. Based on our experience developing Penn State University’s online program in applied statistics, we discuss the evolution of the program’s curriculum, recruitment and development of online faculty, and meeting the requirements of students as important areas that require consideration in the development of an online program. We also highlight program evaluation strategies employed to ensure innovation and improvement in online education as cornerstones to a program’s success. 相似文献

This paper presents a single case study of one street gang in one London borough. Semi-structured interviews were conducted with 12 gang members, or former gang members, and seven practitioners. The practitioners and gang members/ex-gang members reported different perspectives on how the gang was structured and drug dealing was organised. The gang members/ex-gang members suggested that the gang is a loose social network with little recognisable formal organisation. Although individual gang members sell drugs, the gang should not be viewed as a drug dealing organisation. Rather it is a composition of individual drug dealers who cooperate out of mutual self-interest. Therefore, some gang members are best described as independent entrepreneurs while others are subcontractors looking to ‘go solo’. The seven practitioners, however, tended to describe a more hierarchically structured gang, with formal recruitment processes. This divergence of perspective highlights an important consideration for policy and research. 相似文献

This paper examines the effects of organizational attributes on power/dependence relations in interorganizational dyads. Exchange and homophily theories are discussed as two alternative perspectives on the processes that give rise to such effects. The data pertain to interagency ties in three community-based networks of youth service agencies and are analyzed via a new strategy of linear modeling dyadic relations. The results of the analysis suggest that size, administrative position, and justice system connections condition the extent to which an agency initiates and receives ties of influence, assistance, and support. Moreover, these relations are more frequent between agencies with similar treatment ideologies and client racial makeup. Finally, size and justice system access are found to reduce agency dependence on a network's administrative core. In the course of the discussion, a number of related issues and findings are discussed. 相似文献

This paper is an attempt to build upon Pierce's important finding, a confirmation of Durkheim, that any form of economic disruption or change increases suicide. In this paper, certain aspects of Pierce's method are criticized. The analysis of an expanded and updated data set, using analytic techniques designed for time-series data, suggests that economic disruption per se is not as relevant to the suicide rate as are economic hardship and economic deterioration or improvement. 相似文献
