The tragedy of September 11 highlights the stark contrast between the real and measurable capabilities possessed by one state, and the almost inevitable resentments which the possession of those capabilities engendered in others. The purpose of this article is not to interrogate the strengths and weaknesses of arguments of American decline. Nor is it to speculate at length about September 11th. It is instead to set the scene and try and identify the underlying causes of America's transition from presumed crisis in the 1970s and 1980s to new self-confidence in the 1990s—a self-confidence that some now feel has been shattered by the events of September. While there were important structural reasons why the United States was unlikely to go the way of other powers, it was a peculiar conjuncture of mainly unforeseen developments that combined together after 1989 to improve the U.S. position within the world. We will then move on to discuss the most effective way of characterizing this position. Here, we will mount a defense of the somewhat contentious notion of "hegemony" While recognizing the problems associated with the idea, it will be argued that as a concept it has serious intellectual advantages over its various theoretical competitors. If nothing else, because it focuses on the American role within the world system, rather than just its statically defined position, it is theoretically more suggestive than the less dynamic idea of unipolarity.  相似文献

Das Bundesverwaltungsgericht hat in seinem Urteil vom 16.3.2006 zum Gro?flughafen Berlin-Brandenburg in einem Leitsatz festgestellt, dass das FFH-Schutzregime, dem bestimmte Biotope unterliegen, sich nicht auf V?gel erstreckt, denen das betreffende Biotop als Habitat dient. Diese Feststellung führt zu der Frage, inwieweit charakteristische Arten von Lebensr?umen nach Anhang I FFH-RL in der FFH-Vertr?glichkeitsprüfung nach § 34 BNatSchG überhaupt bewertungsrelevant sind. Der Beitrag setzt sich dazu mit dem Urteil kritisch auseinander.  相似文献

Past research has largely ignored the developmental changes within the child that account for the association between parenting and risk for delinquency. We used structural equation modeling and data from a longitudinal study of several hundred African‐American families to test the contentions of various theories regarding the sociocognitive and emotional factors that mediate the impact of parental behavior on a youth's risk for delinquency. Our findings largely supported the theories. The impact of monitoring/discipline was indirect through low self‐control and acceptance of deviant norms, whereas the effect of hostility/ rejection was indirect through low self‐control, hostile view of relationships, and acceptance of deviant norms. These two dimensions of parenting were no longer related either to affiliation with deviant peers or to conduct problems once the effects of these psychological characteristics were taken into account; the impact of these parenting practices was completely mediated by these four cognitive/affective variables. Contrary to expectation, however, these psychological factors did not mediate any of the relationship between caretaker involvement in antisocial behavior and child conduct problems.  相似文献

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
