Objectives . Property rights are central to debates about natural resource policy. Governments traditionally have been seen as the appropriate custodians of natural resources for their citizens. More recently, many argue the privatization of property rights will ensure that users have incentives to manage their resources well. Common property, to the extent it is discussed at all, is seen as leading to the tragedy of the commons. We evaluate these claims by assessing property rights and forest conditions in two private and three communal forests in Guatemala. Methods . Data on biological and social phenomena from five forests (151 plots) and their associated communities were collected using the International Forestry Resources and Institutions Research Program protocols. Ordinary least squares regression was used to analyze four models. We examined t -scores for differences in coefficients for the different models. Results . The models demonstrate that de jure property rights are not a powerful predictor of variations among the sampled forests. Conclusions . We argue that de facto institutions and their enforcement are much more important than de jure property rights to forest management. Communities holding a forest in common can, under certain circumstances, create institutions to manage their resources as successfully as—or more successfully than—private owners.  相似文献

This article presents an overview of the current state of the reforms of the British NHS instigated by the NHS and Community Care Act (1990) following the White Paper Working for Patients (1989) and introduced in England and Wales in 1991 and in Scotland and Northern Ireland in 1992. The reforms were not only wide ranging—affecting virtually all aspects of health care organization and delivery—but also ongoing. Moreover, there has been little systematic evaluation of the impact of the reforms. While making reference to other aspects of the reforms this survey article concentrates on two important issues of central concern to the NHS—efficiency and equity—and highlights some of the associated research and literature.  相似文献

We are concerned in this paper with the question of what more there is to human nature than cognition, with what it is to be a person (or animal) in the sense of something that would justify our sympathy. We examine pain, emotion, and the abrogation of values as sources of our sympathy for one another. We further argue that our sympathy over each of these unfortunate events is connected with our sense that they are beyond a person' s (or an animal' s) will. Computers, we suggest, ought not to engage our sympathy not because of their limited cognitive capacity, and not because they lack intent, but because their wills are too free.  相似文献

This is a biography of an amusement park, Cedar Point in Sandusky, Ohio, by its marketing director. This life history, using sources close to the park and in the popular press ouer many decades, traces the many shifts in circumstance, philosophy and mood in its development ouer a span from 1897 to its present status as “one of the great parks of the country.” This case study of a single park that has incorporated characteristics of many growth stages ofparks ingeneral serues as a capsule history: from its beginnings as a resort; expansion of rides and attractions during the flush years of the 1920s; the backsliding deterioration of the Depression years and the immediatepost- War period; the decline of the big-city parks and the moue to the suburbs in the 50s; and the Disney effect: the advent of the national super theme park, with its revolutionary impact on the traditional park concept. According to Hildebrandt, Cedar Point is “the only modern superpark that also has an ancient history…. the only old-time amusement park to successfully make the transition to the new amusement park culture.”  相似文献

Correspondence to John Harris, School of Health and Social Studies, University of Warwick, Coventry CV4 7AL, UK. E-mail: j.harris{at}warwick.ac.uk Summary The notion that social work is an international profession,operating with generally similar goals, methodologies, and commonvalues is considered critically. Examining the political andsocial contexts of three countries with liberal democratic governments—Australia,Britain and the United States—the role of social workwithin the welfare processes of each country is compared. Whilesocial work as an identifiable professional activity sharessome features, it is argued that the idea of its having a coreessence needs to be tempered with a realistic assessment ofthe importance of contextually created difference. Recent andrapid developments in the institutional context, such as thoseexperienced in these three countries, further underscore thelimited utility of the notion of a common professional project.  相似文献
