Baumgartner and Jones (1993) showed how radically new policies emerge on government agendas as a consequence of exogenous shocks to policy subsystems displacing privileged interests. But how do these policies evolve post-punctuation? In this paper, we present three different models of policy change. Policies may revert to the old status quo if displaced interests re-assert themselves, or they may be “locked-in” by new interests now reaping the benefits. Alternatively, they may incrementally change as lawmakers “learn” how to better meet target population needs, particularly by witnessing how other jurisdictions address similar problems. We test these models with data on change in state charter schools laws over time. We find that whether old status quos are overthrow, and the fate of charter policies when they are enacted, is influenced more by competing political interests, especially interest groups, than elite and public perceptions of broad systemic crises. Yet, we also find that changing demands on the state and learning from the successes and failures of neighboring states also play significant roles. 相似文献

Evidence is presented regarding strengths and limitations of portfolio approaches as applied to diversifying export earnings. An empirical application using data from Malawi, Tanzania, and Zimbabwe is used to demonstrate these strengths and limitations. Modifications of the typical portfolio approach to export diversification are presented; these modifications help make the approach more plausible for use in developing countries. The modified approach is shown to provide guidance to policymakers who seek simultaneously to increase export earnings and reduce their instability. 相似文献

The United States has faced at times the policy dilemma of seeing conflict erupt between two countries with which it maintains friendly diplomatic relations. The bureaucratic biases of relevant agencies can play an important role in determining whether to choose sides or remain neutral in these conflicts. In the early 1960s the Africa Bureau adopted a pro-Ethiopia bias that shaped American policy in the Horn of Africa. With the insights provided by the 2010 Wikileaks cables, this analysis explores how the “Ethiopia imperative” affected three inter-related American policy decisions in the Horn of Africa in the early twenty-first century: the decision to support Ethiopia despite its refusal to abide by a legally binding decision that favoured Eritrea following the 1998–2000 Eritrea–Ethiopia border war; to give Ethiopia what amounted to a “blank cheque” to invade Somalia in December 2006 and overthrow the Council of Islamic Courts (CIC); and to confront and isolate Eritrea diplomatically for waging proxy war against Ethiopia in Somalia. 相似文献

The purpose of this article is to examine how various forms of reasoning both can and should be used to decide cases in the common law tradition. I start by separating positive questions about what the law is from normative questions about what the law ought to be. Next, I present a Peircean account of three main forms of reasoning – deduction, induction and abduction – and examine how they can be used by judges to decide cases in the common law. Finally, I argue that the three forms of reasoning can be used to answer both kinds of questions, but in different ways. All three forms of reasoning can be used to answer questions of positive law, while questions of normative law present a special case that may require the use of aesthetic judgments of taste in the formation of a legal hypothesis. 相似文献

The interstate compact as a policy tool has a long history ofuse in the United States. Yet some observers feel that interstatecompacts have never lived up to their potential. Nevertheless,in 1980, the compact was chosen as the policy instrument tosolve one of the thorniest environmental policy issues of thedecade: the siting of low-level radioactive waste (LLRW) disposalfacilities. Drawing from research on interstate compacts andon alliance theory developed in international relations, thisarticle applies five key questions to the case of LLRW: Whydo states join compacts? Which compacts will they join? Howstable are the compacts? How important are outside factors?What types of situations are compacts most suited to address?It concludes with lessons that should be useful to future policymakersabout the use of interstate compacts to solve salient, nationwidepolicy problems. 相似文献

The question of when adolescence ends and young adulthood begins is considered. Throughout, it is addressed in terms of the theory of broad and narrow socialization, which emphasizes the cultural context of development. The question is approached from cognitive, emotional, and behavioral perspectives, then from the perspective of role transitions (such as marriage and parenthood). The idea of an extended path from adolescence to adulthood is discussed, and the concept of emerging adulthood is presented. It is suggested that in most non-Western cultures the entrance to adulthood is socially defined and marked by a social event, usually marriage. In the contemporary West, however, where there is a strong emphasis on independence and individualism, the entrance to adulthood is defined and marked individually. Consequently, it is likely to be based on the achievement of residential and financial independence as well as on the attainment of cognitive self-sufficiency, emotional self-reliance, and behavioral self-control. Thus in the contemporary West the passage from adolescence to young adulthood is a process that is gradual and may take many years.This research was funded partly by an institutional training grant from the National Institute of Mental Health 5T32 MH14668-14, for the Clinical Research Training Program in Adolescence, jointly sponsored by the Department of Psychiatry at Northwestern University and the Committee on Human Development at the University of Chicago.Received Ph.D. from University of Virginia, Research interests include adolescent reckless behavior, adolescents' uses of media, and the transition to adulthood.Research interests include the transition to adulthood and development in young adulthood. 相似文献
