Many tout the benefits of collaborative environmental management as an alternative to centralized planning and command and control regulation, but the excitement over collaborative processes has not been matched by evidence that these processes actually improve the environment. The most crucial question in collaborative environmental management remains unanswered and often unasked: To what extent does collaboration lead to improved environmental outcomes? We know much about why collaboration is occurring and how collaborative processes and outputs vary. The primary goal of future research on collaborative environmental management should be to demonstrate whether collaboration improves environmental conditions more than traditional processes and newer market-based processes. Collaboration is not a panacea; it is a choice that policy makers and public managers should make based on evidence about expected outcomes.  相似文献

Scholars have long debated the individual-level relationship between partisanship and policy preferences. We argue that partisanship and issue attitudes cause changes in each other, but the pattern of influence varies systematically. Issue-based change in party identification should occur among individuals who are aware of party differences on an issue and find that issue to be salient. Individuals who are aware of party differences, but do not attach importance to the issue, should evidence party-based issue change. Those lacking awareness of party differences on an issue should show neither effect. We test our account by examining individuals' party identifications and their attitudes on abortion, government spending and provision of services, and government help for African Americans using the 1992-94-96 National Election Study panel study, finding strong support for our argument. We discuss the implications of our findings both for the microlevel study of party identification and the macrolevel analysis of partisan change.  相似文献

Abstract.  Over the years, many scholars have examined the relationship between electoral systems and measures of voter satisfaction with democracy. The tendency in these studies has been to explore the traditional Proportional Representation/non-Proportional-Representation dichotomy, assessing whether more proportional systems produce higher levels of satisfaction. This article examines another dimension of electoral system variation – namely the degree to which the ballot structure incorporates ordinal, or preferential features. Given that proponents of such systems extol their virtues as offering voters 'greater choice', it is interesting to explore how this actually plays with the voters. The article makes use of cross-national data from the comparative Study of Electoral Systems (CSES) project to examine the relationship between preferential voting and levels of satisfaction with democracy.  相似文献

All voting is strategic because the shared outcomes are note within the choice set of any voter, the elements of which can only be strategies. Voting behavior need not re- flect the individual's ordering of outcomes, and the conventional distinction between sincere and sophisticated voting is misguided. In voting choice, the ordinal ranking of outcomes must be supplemented by intrapersonal evaluation of utility differences among these outcomes and also by predictions concerning the behavior of other participants in the nexus of interdependence.  相似文献

Through the lens of Guatemala’s Jorge Carpio Nicolle case I analyze the mechanisms that preserve impunity in Latin American nations struggling to emerge from violent conflict and embrace, the rule of law. I reveal how the infective influence of parallel powers, the ineffectiveness of the judicial process, and obstructive legal doctrine destroy domestic efforts to prosecute those responsible for human rights violations. The Carpio case exposes the role of international courts in providing justice when domestic courts fail to do so, and it demonstrates the importance of human rights groups in pursuing this justice. The author would like to thank Roxanna Altholz, Adriana Beltran, and Soraya Long for their invaluable assitance in conducting this research.  相似文献

This article examines the impact of political institutions on the strength of executive governments as well as the consequences of that strength for policymaking. It argues that both political changes and electoral reforms in Japan and Sweden have weakened the political frame for “negotiated” or “coordinated” decision making in these nations. In Sweden, however, the complete demolition of the old political frame has opened up opportunities and incentives for new modes of governance. In Japan, by contrast, reforms have buttressed rather than dismantled the old frame, impeding the transition to a new approach.  相似文献

In this work, we established a procedure for evaluation of the efficiency of the water supply. This procedure has allowed us to find that the proposed indicators have a discriminating capability in the analysis of the service, and to reject criticisms traditionally assigned to the sensitivity of the data envelopment analysis (DEA) technique in relation to degrees of freedom. The results obtained show that the population density, as a factor that defines one of the particular characteristics of the surroundings of each municipality, has a statistically significant impact on the indexes of efficiency, this affirmation not being extended to the public or private ownership of the service. The scale inefficiency is higher than the technical inefficiency. These typologies of efficiency are, principally, motivated by the supply side of the service, which is specially linked with the necessary infrastructure. The demand of the citizens is satisfied with a behavior close to optimal.  相似文献
