ABSTRACT

Leadership decapitation, as a means of hindering the operations and hastening the demise of terrorist organizations, has been the subject of a growing body of research. However, these studies have not examined how an organization’s position in a broader network impacts its ability to weather decapitation. We argue that highly networked organizations possess characteristics that make decapitation less effective. To test this argument, we combine data on leadership decapitation with network data on terrorist organizations and find that well-networked organizations are resilience to leadership decapitation. Our study has implications for our understanding of how terrorist organizations respond to counterterrorism efforts.  相似文献

From a normative standpoint the media are usually seen as one of the pillars of a national integrity system, entrusted with the tasks of exposing and preventing acts of corruption and educating the public of the harm caused by corruption. Nevertheless, corruption continues to be one of the most significant challenges that Europe faces, undermining citizens' trust in democratic institutions and weakening the accountability of political leadership. Evidence suggests that in fragile EU democracies such as Bulgaria, despite more than eight years of full membership and numerous preventive measures, corruption is rife and the press is hardly capable of exposing abuses of power or authority. On the contrary - drawing on in-depth interviews with 35 Bulgarian journalists - this paper argues that since communism collapsed in the late 1980s the media in post-communist societies such as Bulgaria has gradually become an instrument to promote and defend private vested interests, and is plagued by corruption. Senior journalists and editors cast serious doubt over the ability of the post-communist free press and journalism to act as a watchdog for society.  相似文献

Previous research reveals that showups are an inferior eyewitness identification procedure to lineups, but no single study has compared younger and older adults' identification decisions for both of these procedures. We had witnesses watch a mock crime video and then make an identification decision from a fair lineup, a biased lineup, or a showup that contained the perpetrator or a designated innocent suspect. Receiver operating characteristic (ROC) analysis showed that identification accuracy was higher from a lineup than from a showup for both age groups, even if the lineup was biased. In addition, calibration curves revealed that witnesses were underconfident when choosing from a fair lineup but overconfident when choosing from a showup. These results reinforce prior research asserting the superiority of lineups over showups.  相似文献

Sandy and Devine (1978) theorized that small-town and rural police officers experienced Stressors different from their urban counterparts. They delineated four rural stress dimensions: security, social factors, working conditions, and inactivity. Despite the number of hypotheses annunciated by these authors from their exposure to small-town and rural police, they have never been tested. This study is an attempt to rectify this deficiency in the literature by testing their theory/hypotheses with data derived from a survey questionnaire of West Virginia law enforcement officers. The findings of this study lend support for many of the original hypotheses and all four of the dimensions.  相似文献

The tournament model is a widely used mechanism to control opportunistic behavior by associates in law firms. However, this mechanism can only operate in certain economic (and social) circumstances. When those circumstances do not exist, the model breaks down, and with it the ability to control opportunism in the absence of some alternative mechanism. Prior research has not investigated whether the utilization of a tournament model prevents the opportunistic behaviors identified as grabbing, leaving, and shirking. In order to test the limits of the tournament model, it is necessary to find particular historical moments when the economic environment radically challenges assumptions/premises of the model. The dot-com bubble in Silicon Valley provides precisely such a time and place. This article demonstrates limits to the applicability of tournament theory. Those limits are to be found in the economic environment in circumstances in which: (1) exogenous reward structures offer many multiples of internal rewards; (2) demonstrably high short-term rewards outside the firm starkly contrast with the delayed long-term rewards inside the firm; (3) the managerial strata reduce their emphasis on long-term recruiting of potential partners in favor of short-term productivity by young associates; and (4) firms develop departmental leverage ratios in excess of their capacity to monitor, mentor, and train recruits.  相似文献

Recent advances in immunology have provided a foundation of knowledge to understand many of the intricacies involved in manipulating the human response to fight parasitic infections, and a great deal has been learned from malaria vaccine efforts regarding strategies for developing parasite vaccines. There has been some encouraging progress in the development of a Chagas vaccine in animal models. A prize fund for Chagas could be instrumental in ensuring that these efforts are translated into products that benefit patients.  相似文献
