Using survey data, various measures of self-control, based respectively on cognitive and behavioral indicators, are compared in their ability to predict eight measures of crime/deviance. The results show that either type of measure produces supportive evidence for the theory, and the behavioral measures provide no better prediction than do the cognitive measures. Unlike cognitive type indicators, and contrary to the implications of the theory, different types of crime-analogous, imprudent behaviors are not highly interrelated, making it difficult to develop reliable behavioral measures. These results suggest that general support for self-control theory would likely not be any greater if all researchers had used behaviorally based measures, as recommended by the authors of the theory. Improving the level of prediction to the point where self-control could claim to be the master variable, as envisioned by its proponents, does not seem to rest on a shift to behaviorally based measures. Instead, improvements in the theory itself, particularly the incorporation of contingencies, appears to offer more promise. 相似文献

Overcoming challenges to ecosystem health calls for breaking down disciplinary and professional barriers. Through reflection on a research and development project to address pesticide-related concerns in northern Ecuador, this article presents challenges encountered and accommodations made, ranging from staff recruitment, through baseline assessments and community education activities, to mobilising for policy change. In so doing, it exposes underlying problems of paradigm and process inherent in bringing researchers and development practitioners together, in addition to the problematic role of advocacy that is associated with joint research and development initiatives in the fields of agriculture and health. 相似文献

We discuss how the Registered Traveler (RT) program can enhance simultaneously aviation security and passenger convenience. We point out some of the potential weaknesses in the program from both a security and civil liberty perspective. The RT program is a public–private partnership between the Transportation Security Agency (TSA) and the private sector. As in any partnership between private enterprises and the public sector, there are tensions that must be monitored, managed, and resolved. We note that financial distress of a RT service provider will place increased pressure on TSA resources. We review the resources allocated by the public and private sectors and the natural tensions that exist between companies investing capital with the expectation of earning a market rate of return and an agency of the Department of Homeland Security, the TSA, with one of its responsibilities being to assure the safety and security of air travel. 相似文献

This article examines aspects of planning, budgeting and reorganization in order to evaluate what improvements have been undertaken during the Clinton presidency to improve government performance in the United States national government 1 . The authors develop a model of government reform based upon a series of escalating steps. These are: (1) internal government improvements; (2) fundamental restructuring and reorganization of agency operations; (3) programme reforms, driven by internal management; (4) programme reforms – driven by policy and political change; (5) reform of the political system itself. The authors conclude that while the National Performance Review and Government Performance and Results Act are the centre-pieces of this effort, reform will continue in the US after NPR
and GPRA wither away because the time is right for reform for a variety of reasons discussed in the article. The findings are then focused in a broader context in terms of their applicability to western democracies which could result in smaller more successful governments in the twenty-first century. 相似文献
