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

There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.

Public management networks (PMNs) continue to proliferate as governance becomes more complex, and so does the need to hold them accountable. Agency and collaboration theories provide a solid foundation, but additional constructs are necessary to adapt to this dynamic era. Building from Bovens et al. (2008), the authors offer an ecological framework of third-party accountability that incorporates a number of prominent accountability theories under the same construct. Employing a mixed-methods research design that examines eight local PMNs in the Chicago region, the study finds that an exemplar accountability mechanism—additional cost monitoring—occurs more often in situations predicted by the framework. Additionally, qualitative interviews of network participants suggest that cost structures can differ by network type, which is verified quantitatively.  相似文献

Aviation expansion and the construction of a third runway at Heathrow airport is firmly back on the political agenda. Yet, the stark fact remains that a growing list of British governments has been unable to engineer a partial or temporary policy settlement in aviation. In exploring the challenges of reaching such a settlement, this article characterises the shifting and contested political and policy contexts of UK aviation. It begins by exploring the ‘wicked issue’ of aviation expansion before foregrounding how the politics of air travel is riven by competing policy frames, fragmented governance and the absence of gatekeepers. It argues that the Davies Commission and its efforts to remove aviation from the domain of partisan politics provided little more than a temporary respite for government. It thus concludes by questioning whether the May government's expansion proposals will succeed this time around, outlining how the contributions in this collection address the themes and issues of this overriding policy puzzle.  相似文献

An increasing number of citizens change and adapt their party preferences during the electoral campaign. We analyze which short-term factors explain intra-campaign changes in voting preferences, focusing on the visibility and tone of news media reporting and party canvassing. Our analyses rely on an integrative data approach, linking data from media content analysis to public opinion data. This enables us to investigate the relative impact of news media reporting as well as party communication. Inherently, we overcome previously identified methodological problems in the study of communication effects on voting behavior. Our findings reveal that campaigns matter: Especially interpersonal party canvassing increases voters’ likelihood to change their voting preferences in favor of the respective party, whereas media effects are limited to quality news outlets and depend on individual voters’ party ambivalence.  相似文献

The question of what constitutes torture has perhaps never held as prominent a place in US political discourse as it has since the attacks on 9/11. This has fueled a national conversation that causes us to consider to what extent do our actions as a nation reflect our values as a nation? In a post 9/11 world in which the country will confront terrorism at home and abroad and our values will be tested we should strive for a better understanding of citizens' attitudes towards the practices that are (and have been) used to counter terrorism. To the extent that democratic theory is correct in necessitating public policy and public opinions to be reasonably congruent, understanding the distribution and formation of citizen attitudes towards torture is an important endeavor.  相似文献

This article analyses intervention and statebuilding as shifting towards a posthuman discursive regime. It seeks to explore how the shift to ‘bottom-up’ or post-liberal approaches has evolved into a focus upon epistemological barriers to intervention and an appreciation of complexity. It attempts to describe a process of reflection upon intervention as a policy practice, whereby the need to focus on local context and relations – in order to take problems seriously – begins to further undermine confidence in the Western episteme. In other words, the bottom-up approach, rather than resolving the crisis of policy practices of intervention, seems to further intensify it. It is argued that the way out of this crisis seems to be found in the rejection of the aspiration to know from a position of a ‘problem-solving’ external authority and instead to learn from the opportunities opened up through the practices of intervention. However, what is learnt does not seem to be able to fit into traditional modes and categories of expertise.  相似文献

The resilience of some high-profile white-collar criminals in the media gaze after prison may lead some to conclude, particularly as some research also supports this notion, that this group of offenders generally manages well after conviction. Research in this area is, however, small and largely American. The authors seek to add to this small body of research by offering findings on the impact of conviction on 17 UK convicted white-collar criminals after completion of their sentence. It provides a unique insight into the consequences of conviction, showing that although there were some offenders who did experience limited impact and coped well, there was also a significant group who suffered a decline in status, financial losses, negative media coverage, and relationship and mental health problems, to name some. The authors argue more research is needed on this group and their needs as they are often neglected by the criminal justice system.  相似文献
