Political opposition,external threats,and elite responses: analyzing domestic security policy in post-Rose Revolution Georgia

In the years since the 2003 Rose Revolution, the popularly elected leadership of the Republic of Georgia has responded to organized protests with a variety of repressive tactics. These reactions suggest that former challengers to authoritarian elites may utilize similar methods of retaining power during crisis periods. Yet, the alleged involvement of agencies of the Russian Federation in fomenting domestic instability has also occupied a central position in the national security policies of the outgoing Saakashvili government. These conditions both preceded and were reinforced by the South Ossetia War of August 2008. This article proposes a theoretical model that represents the intervening effect of interstate conflicts on state–society relations in Georgia from 2003 to present. It presents several hypotheses and possible indicators, data sources, and techniques for analyzing the interaction between characteristics of opposition groups, external threats, and the domestic security practices of contemporary Georgian political elites.     

Does counterterrorism spending reduce the incidence and lethality of terrorism? A quantitative analysis of 34 countries

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.     

The Finger on the Button

Taiwan's international status is such that the country's ability to trade and to supply certain goods and technologies remains its primary means of practicing diplomacy and asserting international influence. U.S. pressure to conform to international nonproliferation standards has made the issue of export controls a troubling one for Taiwan. Limiting Taiwan's economic relations affects its ability to sustain itself economically and to maintain productive relations with other nations. On the other hand, as a recipient of U.S. high-technology transfers and security assurances, Taiwan cannot ignore the directives of the United States. The article focuses on this dilemma and how a shift in power to the Democratic Progressive Party is affecting Taiwan's choice between placing limitations on its global economic power or risking being cut off from U.S. technology and losing U.S. security assurances. In order to address this challenge properly, Taiwan will need to reassess its fundamental economic and security interests.     

THE ORIGINS OF AND PROSPECTS FOR RUSSIAN NUCLEAR DOCTRINE

This article explores Russia's increasing reliance on nuclear weapons from three perspectives. First, it seeks to demonstrate that the phenomenon is not exclusively limited to Russia and represents a broader trend, which is ultimately rooted in the nature of the contemporary international system or, more precisely, the uncertainties of the transitional period between the Cold War system and a new emerging one. Second, it analyzes the role assigned to nuclear weapons in Russia's doctrinal documents, in particular the emergence of a new mission—limited-use of nuclear weapons to deter or, if deterrence fails, to de-escalate large-scale conventional conflicts. Discussions of the new doctrine, which have begun recently, suggest that this new mission will likely remain unchanged. Finally, this article looks at the apparent discrepancy between Russia's nuclear modernization programs and the roles assigned to nuclear weapons in the military doctrine, as well as the causes of that discrepancy.

海洋拖曳系统运动方程的变步长有限差分数值仿真

有限差分算法是常用的海洋拖曳系统运动仿真计算方法,传统的有限差分算法在对拖缆进行离散时,采用固定空间步长,为了提高数值计算的精度,通常需要减小空间步长,这既增加了计算时间,又浪费了计算机内存,甚至造成无法仿真一些工况。针对这一问题,提出了变步长有限差分数值算法,给出了步长变化的设定原则与算法,在建立海洋拖曳系统运动模型的基础上,系统分析了这一方法的求解思想与过程,并分别采用传统固定步长有限差分算法(大空间步长和小空间步长)和变步长有限差分算法,对模型进行了数值仿真,结果表明:变步长有限差分算法不仅保证了仿真计算精度,而且降低了计算机内存需求量,减少了计算时间。此外,变步长有限差分算法具有较高的灵活性,可根据实际情况,综合考虑计算时间、内存需求量和计算结果精度,从而选择合适的空间步长变化规律。
