River basins have provided resources for the advancement of human civilization from the earliest historic times. With river basin development has also come conflict, particularly in the past century. In response, the international community has developed generalized, global principles for the equitable allocation of water resources between nation-states, most notably through the 1997 United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses. These principles, however, have rarely been explicitly put into practice. To resolve or avert conflict in the world's 261 international river basins, riparian nations have instead relied upon treaties that incorporate basin-specific needs and conditions and define equity at the most local level. An examination of the progression of geographic thought on river basin development reveals a spatial focus that has not evolved beyond the basin and landscape scales. The absence of theoretical underpinnings for global frameworks may explain why riparian nations have not widely adopted general principles for the equitable allocation of water resources in actual treaty practice.  相似文献

Conducting physical searches for mass grave locations based on anecdotal evidence is a time-consuming and resource-intensive endeavor in circumstances that often pose a threat to personal safety. The development of tools and procedures to speed such searches can greatly reduce the risk involved, increase the number of individuals whose remains are recovered and identified, and more importantly, reunite these remains with their loved ones to provide them with a proper burial. Geographic information systems (GIS) software, which can analyze and manipulate the spatial characteristics of known mass grave data, represents a powerful tool that can be used to predict new mass grave locations and increase the speed and efficiency with which they are investigated. Using the open source QGIS project, existing mass grave locations in Guatemala were analyzed based on their distance from and change in elevation relative to roads, streets, waterways, points of interest, and possible villages/towns. Statistical and geostatistical analyses performed to detect relationships among the variables resulted in patterns that warrant further study and can be used to further narrow areas of investigation.  相似文献

How does America's high rate of incarceration shape political participation? Few studies have examined the direct effects of incarceration on patterns of political engagement. Answering this question is particularly relevant for the 93% of formerly incarcerated individuals who are eligible to vote. Drawing on new administrative data from Connecticut, we present evidence from a field experiment showing that a simple informational outreach campaign to released felons can recover a large proportion of the reduction in participation observed following incarceration. The treatment effect estimates imply that efforts to reintegrate released felons into the political process can substantially reduce the participatory consequences of incarceration.  相似文献

New federal support for improvement in the handling of child welfare cases has made it possible for juvenile and family court judges to assess how well courts are implementing the Adoption Assistance and Child Welfare Act of 1980. This article first describes the purposes of the Act, and then suggest 23 steps to consider in attempts to improve the court process.  相似文献

The Industrial Extension Service of North Carolina State University's College of Engineering is in the seventh year of a unique program that promotes the use of new technologies and current best practices, demonstrates their application in industry, and offers university services for implementation. Described here are the activities and operation of this North Carolina-only program, as well as examples of cooperative applied research that are fostered by it.  相似文献

This article offers a contribution to the debate in recent issues of this journal concerning the relative 'newness' or otherwise of New Labour. It briefly assesses the significant arguments of the respective academic protagonists and asks if, in responding to a changing social and economic climate, New Labour, the highly focused use of language and rhetoric aside, is, in a significant sense, different to the measured, pragmatic and reformist revisions of the past. It emphasises significant associations and continuities in Labour's recent evolution and the largely rhetorical and politically (and electorally) expedient nature of the party's current designation. It offers an interpretation of New Labour, based around two related observations of the party's historically broad and complex political culture and diverse perceptions and preferences of Labour's traditionally centre-right 'governing elite', that suggests that the post-1994 'New' Labour party possesses significant precedents within elements of Labour's diverse, centre right 'dominant coalition'.  相似文献
