This paper addresses the relationship between accumulated knowledge and U.S. policy dealing with failed states and terrorism. The central thesis is threefold: (1) that more was known about the possible linkages between failing states and terrorism than appears in pre-9/11 U.S. policies; (2) that since 9/11 some important realignment of knowledge and practice has occurred, but it remains partial and incomplete; and (3) that new knowledge, especially about the policies to sustain and promote legitimate governance, needs to be generated in order to support an effective grand strategy for addressing the threats and challenges of the twenty-first century. The paper recommends such a grand strategy and, in addition to the required new knowledge, a significant reorganization of the U.S. national security policy-making apparatus. International studies curricula appear well suited for contributing to that new knowledge and the practitioners we require. 相似文献

The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations. 相似文献

Investigative bodies and other observers have attributed much of the blame for the 1985 MOVE catastrophe in Philadelphia to ineffective management by the city's previously successful mayor, W. Wilson Goode. Goode's behavior toward the disruptive extremist group followed two patterns, both paradoxical: protracted delay followed by excessive haste, and arms-length action that contrasted sharply with his usual hands-on management style. Drawing on the theory of decisionmaking developed by Irving Janis and Leon Mann, this paper suggests that both paradoxes resulted from unresolved decisional conflicts that impeded responsible and rational handling of the problem. The case points to the value of devoting more attention to the psychology of decision-making in educating present and future public managers. 相似文献

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and
incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and
a half have gradually shifted in terms of ownership and management from university/research institute to the private sector
and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture
capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful
innovative companies will emerge in larger numbers than in the past.

This article contributes to the development of theories on European integration by testing and exploring statistical models
on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from
the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003.
We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional
theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic
models might be an interesting avenue for future conceptualizations of the EU integration process.
This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to
thank the seminar participants for useful comments. 相似文献

Banks are “special” financial institutions generating distinct corporate governance challenges. The present paper examines
the relationship between two of the most pertinent corporate governance factors—that is, the size of the Board of Directors
and the proportion of non-executive directors—and firm performance on a sample of 58 large European banks over the period
2002–2004. The empirical analysis embraces a number of bank-specific variables. Our results reveal that bank profitability
is negatively related to the size of the Board of Directors, while the impact of Board composition, although positive in all
models, is, in most cases, insignificant. The results are robust after controlling for firm-specific variables.

This article explores the different and sometimes conflicting explanations of the success of the collective enterprises (town–village-enterprise) in China during the first phase of transition (1979–1995). It is argued that explanations, relying on cultural variables are not sustainable and this for two reasons. First, the importance of the collective enterprise is shrinking while the private sector is clearly on the rise. Second, other factors, referring to characteristics of the local and central political, administrative and economic environment, in which the Chinese enterprise has to (had to?) operate, provide for a sufficient explanation of the peculiar structure of the Chinese collective enterprises. These enterprises are seen as the result of ?bureau-preneurship’ because local bureaucrats were integrated in their management in order to pre-empt predatory behaviour and to facilitate the relationships with the central institutions. The article contributes to the property rights’ theory of the firm as it analyses an empirically very important case in which firms with unclear property rights and structures, apparently not conducive for incentives, might still be the most efficient option. 相似文献
