Following the 11 September 2001 attacks, the US government increased its counterterrorism (CT) funding and created several Federal Agencies such as the Department of Homeland Security; Transportation Security Administration; and National Counterterrorism Center. Similarly, the 7 July 2005, London bombings also compelled the British government to increase its CT funding. These examples illustrate a phenomenon that when states experience terrorism, they dramatically increase public safety spending in order to reduce or eliminate the incidents of and casualties resulting from acts of terror. Using statistical data collected from 34 countries covering nine years, this article examines recent CT spending increases. Critically, the authors explore whether recent public safety expenditures can measurably reduce the number of domestic and international terrorist attacks. The implications of their findings should be salient for policy-makers’ assessments of their countries’ current CT strategies and policies concerning their respective Intelligence and Security Communities. 相似文献

The exploits of the A.Q. Khan nuclear network have received significant attention in the last three years. Gordon Corera's recent book, Shopping for Bombs, is an important addition to the existing literature. In this book, the author explores how Khan became a nuclear supplier and why his network was able to flourish for so many years. In his analysis, Corera examines relevant domestic and international political circumstances that affected Khan's rise and ultimate fall. The author also gives a compelling account of the international investigation that shut down this network in 2004 and warns that Khan's network will not be the last to challenge international nonproliferation regimes. Despite a few gaps in the book's narrative and analysis, Shopping for Bombs is an important source of insight into the activities of Khan and his network. 相似文献

AbstractThe Sword of Honour (RA IX.1841) presented in 1856 by the Province of Nova Scotia to its native son, General Sir William Fenwick Williams, Bart. for his deeds at Kars, Turkey, is described, illustrated, discussed and placed both in its historical and its design context. Other notable British swords of the Victorian Age (1837–1901), the Age of Empire, are also examined and the various and influential aspects of their designs, ornament and iconography discussed. 相似文献

本文对二甲苯溶剂中MeSiHCl2 和甲醇的反应产物Me (OMe)2SiH 及MeSi(OMe)3 作了红外和核磁共振分析, 结果表明: 以红外谱图中Si-H 和苯环吸收带作为含量分析谱带, 采用比例法, 借助工作曲线,可确定反应产物的含量。亦可以通过对各组分处于不同化学位移下质子的核磁共振分析,采用归一化法,经过换算测定反应产物混合液中各组份含量。两种测定方法均简便快捷, 并对两法的测定结果作了分析比较。 相似文献
