This article claims that the ongoing debate about the structure and dynamics of Al Qaeda has failed to appreciate the importance of an organizational layer that is situated between the top leadership and the grass-roots. Rather than being “leaderless,” it is the group's middle management that holds Al Qaeda together. In Clausewitzian terms, Al Qaeda's middle managers represent a center of gravity—a “hub of … power and movement”—that facilitates the grass-roots’ integration into the organization and provides the top leadership with the global reach it needs in order to carry out its terrorist campaign, especially in Europe and North America. They are, in other words, the connective tissue that makes Al Qaeda work. The article substantiates this hypothesis by providing a number of case studies of Al Qaeda middle managers, which illustrate the critical role they have played in integrating the grass-roots with the top leadership. The policy implications are both obvious and important. If neither the top leadership nor the grass-roots alone can provide Al Qaeda with strategic momentum, it will be essential to identify and neutralize the middle managers, and—in doing so—“cause the network to collapse on itself.” 相似文献

Do economic perceptions influence partisan preferences or vice versa? We argue that the direction of influence between government approval and economic perceptions is conditional on the state of the economy. Under conditions of economic crisis, when economic signals are relatively unambiguous, perceptions of the economy can be expected to exogenously influence government approval but this is not found when the economy is experiencing a more typical pattern of moderate growth and economic signals are more mixed. We test these arguments using British election panel surveys covering electoral cycles of moderate economic growth (1997–2001) and dramatic and negative disruption (2005–2010). We examine the most commonly employed measures of retrospective economic perceptions and estimate a range of models using structural equations modelling. We demonstrate that when the economy is performing extremely badly economic perceptions have an exogenous effect on government approval and provide a means of electoral accountability, but this is not the case in under more normal circumstances. 相似文献

During the course of a criminal trial, an investigating pathologist is commonly asked how much force was required to produce an injury. This subjective opinion is based on the pathologist's previous experience of dealing with wounds inflicted with similar weapons. However, in the case of stab wounds inflicted by broken glass, it is unlikely that two glass fragments would be physically similar. In the case studied, two theories were examined: that a wound resulted from a thrown glass fragment or that it had been caused as a stab injury by the glass held in the bare hand. The investigation involved quantifying the energy required for human tissue penetration, comparison of sharpness, a biomechanical analysis of throwing actions and testing of the hypothesis that if the glass shard were used as a stabbing implement it would result in a cut to the hand.The investigation utilised a scientific methodology that reduced the need for speculative (though informed) opinion from the pathologist by producing quantitative results. 相似文献

This essay is concerned with two specific issues that have as their backdrop the heroic central figure, the trial lawyer. First it considers the role of screen lawyers in seeking to maintain public (in this sense the public is the community within the film) support for the due process of law. The issue is the link between the lawyer and the initiation of the formal legal process. Essentially it is the extent to which the lawyer defends the institution of law. The second part of the piece considers when screen lawyers are permitted to go outside the formal process of law to ensure that the right result is achieved. It examines instances of where lawyers have been prepared to go 'beyond law' to achieve justice. Such acts raise a number of questions concerning how such behaviour affects perception of the legitimacy of the law, professional ethics, and the relationship between law and justice 相似文献

Investigations into the causes and effects of parallel importinghave concentrated on price discrimination, but arbitrage canalso occur on non-price dimensions. Using a natural experimentin the New Zealand film distribution industry between May 1998and November 2001, we examine the effect of parallel importingon quality as it relates to the timing of the availability offilm media. We demonstrate that (a) cinema revenues were underminedas consumers substituted viewing films on parallel importedDVDs for the cinema format and (b) that studios responded tothe threat of parallel imported DVDs by bringing forward therelease of films into New Zealand cinemas. The reduced delaybetween US and New Zealand cinematic release dates is shownto be consistent with the introduction of competition when timingis a dimension of quality and choice. We conclude that parallelimportation of DVDs almost certainly resulted in a net increasein welfare in New Zealand. 相似文献

Trying to build alliances that span the divide between trade unions and NGOs as well as the divide between the North and the South might seem a utopian task. But this is exactly what an imaginative new generation of organisers from the Western hemisphere's labour movements and NGOs are trying to do. This paper analyses two very different efforts working to bridge this ‘double divide’. The first is a combination of organisations, including unions and NGOs in both North and South, that are focusing on blatant violations of the dignity of workers in apparel export processing zones in the South. This ‘basic rights complex’ has resulted in important victories. A second complex of organisations, also involving unions and NGOs in both North and South, has raised broad macro issues of governance focusing particularly on the anti‐democratic character of current proposals for a free trade area of the Americas. Neither of these complexes is without its weaknesses, but each makes it clear that bridging the double divide should be thought of not as a utopian dream but as work in progress. 相似文献
