Following 9/11, Al-Qaeda-orchestrated plots were considered the greatest threat to Western security and sparked the coalition’s war on terror. Close to a decade later, the post-9/11 threat landscape had shifted significantly, leading then CIA-director Leon Panetta to describe “the lone-wolf strategy” as the main threat to the United States. Subsequent lone-actor attacks across the West, including the cities of London, Nice, Berlin, Stockholm, Ottawa and Charleston, further entrenched perspectives of a transformed security landscape in the “after, after-9/11” world. The unique features of lone-actor terrorism, including the challenges of interdiction and potential of copycat attacks, mean that the media is likely to play a particularly important role in shaping the reactions of the public, affected communities and copycat attackers. This article presents findings from a content analysis of British and Danish newspaper reporting of lone-actor terrorism between January 2010 and February 2015. The study highlights that lone-actor terrorism is framed, with national variations, as a significant and increasing problem in both countries; that Islamist lone-actors are often represented as distinct from far-right lone-actors; and that some reporting, despite relatively limited amplification of specific terrorist messages, potentially aids lone-actors by detailing state vulnerabilities to attacks.  相似文献

The wisdom of the American Psychological Association's submitting amicus briefs to affect social or legal policy is questioned by an analysis of the brief claimed to be a strong example of the effective use of social science data in the public policy arena; namely, the APA brief (Bersoff & Ogden, 1987) inLockhart v. McCree (1986). The data relied upon in the brief do not appear to support the assertions based upon them, and other data are adduced to develop the critique. It is concluded that it is mischievous for the Association to address itself to the courts by generalizing a data base well beyond its useful limits: The adversarial and scientific methods of establishing truth are in several respects antithetical.  相似文献

Correctional facilities are increasingly burdened with mentally disordered offenders and are faced with the formidable task of effectively screening inmates for major mental disorders and suicide potential. Teplin and Swartz (1989) developed the Referral Decision Scale (RDS) as a rapid screen for schizophrenia and major mood disorders in jail populations. However, more recent research by Hart, Roesch, Corrado, and Cox (1993) has called into question the effectiveness of the RDS. In this study, we examined the convergent and discriminant validity of the RDS with the Schedule of Affective Disorders and Schizophrenia—Change Version (SADS-C) and the Personality Assessment Inventory (PAI) on a sample of 108 mentally disordered inmates. The RDS provided moderate evidence of convergent validity but failed to demonstrate acceptable discriminant validity, because of high intercorrelations on RDS subscales (heterotrait-monomethod coefficients). In comparison, the SADS-C yielded similar evidence of convergent validity and excellent discriminant validity.The authors would like to thank the Research Opportunities Program, University of North Texas for its grant support and Captain James Moore for his active cooperation.Tarrant County Mental Health and Mental Retardation Services.  相似文献

An increase in birth rates to Minneapolis minors following the enactment of a parental notification law was examined. A well-publicized link between increasing birth rates and the law is shown to have been premature. Birth, abortion, and population data by age, race, and region suggest that the increasing birth rate in Minneapolis was not related to parental notification, but rather to a growing racial minority population.Preparation of this article was supported in part by an Aldeen Grant from Wheaton College. The authors wish to thank the Minnesota Center for Health Statistics, particularly James Wigginton and Carol Vargas, for their considerable work to provide birth, abortion, and population data in a form suitable for the current analysis. The authors also thank Americans United for Life for purchasing the data and providing them to the authors.  相似文献

With Bill Clinton's new reforms only a month away, the health-care system is on the operating table--and the doctors are under the knife. Americans have a love-hate relationship with physicians: they like the care that doctors provide but hold them to blame for the nation's health-care mess. NEWSWEEK looks at how the culture of medicine may change, assesses doctors' fears--and examines the brave new world of HMOs.  相似文献

Abstract

The Centre for Scientific Research into Plant Medicine, a large herbal medicine research center in Ghana, has received important research equipment and training through a transnational research collaboration involving the Japanese International Cooperation Agency. By situating this project in regional debates about traditional medicine research priorities and the ontologies of plant medicine, this article argues that the collaboration had the perceived effect of standardizing research practices oriented toward drug discovery rather than the rationalization of crude drug preparations. This shows that “capacity-building” components of research collaborations should not be taken as the transfer of neutral goods from one location to another. They are charged with the political potential to make crucial decisions about the objects of research in postcolonial Africa.  相似文献

The literature on intelligence analysis contains many references to the ‘review process’, the mechanism by which analysts’ drafts are converted into corporate products. Analysts whose drafts consistently navigate the process quickly and smoothly are regarded as star performers. Divining the practical meaning of organizational definitions of ‘good’ analysis and the personal preferences of specific senior reviewers is not easy, however. Analysts occasionally commit their understanding of reviewers’ stylistic preferences to paper, effectively providing style guides to help others. This essay presents and explains the development and implications of one such guide, which was designed to help analysts in CIA’s Office of Strategic Research in the early 1970s.  相似文献
