This article examines the role of the Islamic State of Iraq and Syria's (ISIS's) beheading videos in the United Kingdom and the United States. These videos are highly illustrative demonstrations of the importance of visual imagery and visual media in contemporary warfare. By functioning as evidence in a political discourse constituting ISIS as an imminent, exceptional threat to the West, the videos have played an important role in the re‐framing of the conflict in Iraq and Syria from a humanitarian crisis requiring a humanitarian response to a national security issue requiring a military response and intensified counterterrorism efforts. However, this article seeks to problematize the role and status of ISIS's beheadings in American and British security discourses by highlighting the depoliticizing aspects of reducing a complicated conflict to a fragmented visual icon. The article concludes by emphasizing the need for further attention to how the visibility of war, and the constitution of boundaries between which acts of violence are rendered visible and which are not, shape the political terrain in which decisions about war and peace are produced and legitimized.  相似文献

The formation of a coalition government by the Conservatives and Liberal Democrats, combined with the need for important cuts to Britain's armed forces has raised significant uncertainties about Britain's attitude to defence cooperation within the European Union. Since taking office the coalition, while grappling with the implications of Britain's fiscal challenges, has shown an unprecedented interest in strengthening bilateral defence collaborations with certain European partners, not least France. However, budgetary constraints have not induced stronger support for defence cooperation at the EU level. On the contrary, under the new government, Britain has accelerated its withdrawal from the EU's Common Security and Defence Policy (CSDP). This article assesses the approach of the coalition to the CSDP. It argues that, from the perspective of British interests, the need for EU defence cooperation has increased over the last decade and that the UK's further withdrawal from EU efforts is having a negative impact. The coalition is undermining a framework which has demonstrated the ability to improve, albeit modestly, the military capabilities of other European countries. In addition, by sidelining the EU at a time when the UK is forced to resort more extensively to cost‐saving synergies in developing and maintaining its own armed forces, David Cameron's government is depriving itself of the use of potentially helpful EU agencies and initiatives—which the UK itself helped set up. Against the background of deteriorating European military capabilities and shifts in US priorities, the article considers what drove Britain to support EU defence cooperation over a decade ago and how those pressures have since strengthened. It traces Britain's increasing neglect of the CSDP across the same period, the underlying reasons for this, and how the coalition's current stance of disengagement is damaging Britain's interests.  相似文献

Geographer C. W. Thornthwaite proposed in 1948 a moisture index called Thornthwaite Moisture Index (TMI) as part of a water balance model for a new classification system for climate. The importance of TMI climatic classification has been recognised in many areas of knowledge and practice worldwide over the last 60 years. However, although past climate research was focused on developing adequate methods for climate classification, current research is more concerned with understanding the patterns of climate change. The use of TMI as an indicator for climate change is still an incipient area of research. The contributions of this paper are twofold. First, it is to fully document a methodology based on geostatistics adopted to produce a time series of TMI maps that are accurate and have high spatial resolution. The state of Victoria, in Australia, over the last century, is used as the case study. Second, by analysing these maps, the paper presents a general evaluation of the spatial patterns found in Victoria related to moisture variability across space and over time. Some potential implications of the verified moisture changes are discussed, and a number of ideas for further development are suggested.  相似文献

Tony Blair's decision to provide an indication of his departure date from 10 Downing Street has generated interest in the policies and style of his most likely successor, the current UK Chancellor of the Exchequer, Gordon Brown. Brown's ambitions for European policy are considered by a number of commentators to be less clear. This is because so far he has not produced a comprehensive vision of how he sees the UK's future relationship with the EU. However, as this article demonstrates, close examination reveals that his position on many aspects of European policy is actually already well documented.  相似文献
