The Odyssey of the Comprehensive Nuclear-Test-Ban Treaty

This study examines the failures of the William J. Clinton and Barack Obama administrations to secure ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). It applies an integrated analytical framework for assessing treaty ratification that builds upon previous research in order to understand why the Clinton administration failed to achieve CTBT ratification in 1999 and why the Obama administration has so far failed to advance the treaty in the Senate. The study concludes that CTBT ratification, despite Obama administration pledges of support, remains highly unlikely. Finally, the study analyzes the common domestic political factors present in both cases and suggests areas for further research.     

Meeting the growing safeguards burden

ABSTRACT

The International Atomic Energy Agency (IAEA) faces challenges in fulfilling its safeguards mandate as a result of an expanding safeguards burden and a relatively static budget. This dilemma has been exacerbated by the additional burdens of implementing the Joint Comprehensive Plan of Action (JCPOA) in Iran, but would not go away if implementation of the JCPOA were to end. There are three main areas of opportunity for the Agency: (1) budgetary expansion tied to changes in staffing policies, (2) changes in safeguards approaches, and (3) technological innovation. Barriers and limitations are associated with each approach, and advancing any of them will face a difficult political environment in Vienna.     

基于集对分析和LS-SVM的装备研制风险综合评价

【】为了有效防控武器装备的研制风险,确保武器装备项目的顺利推进,提出一种基于集对分析(SPA)理论与最小二乘支持向量机(LS-SVM)方法的装备研制风险综合评价方法。在该方法中,首先,根据武器装备研制的具体特点,建立了装备研制风险评价指标体系。然后,在此基础上,引入SPA分析理论中的联系度和集对概念构建了训练样本和测试样本。最后,使用获取的样本对LS-SVM进行训练和测试,得到装备研制风险评价模型,并据此给出评价结果。案例分析表明,所提出方法过程简便,定性定量结合,形式易于理解,评价结果也更加贴近实际,对于提升装备研制项目风险管理和决策水平,具有重要的实际意义。     

防空兵群射击指挥能力的模糊综合评价方法

射击指挥是防空兵作战指挥的重要组成部分,防空兵群的射击指挥能力,严重影响着整个防空兵群的作战能力。引入模糊评判模型,在分析评价射击指挥能力的各个指标的基础上,对防空兵群的射击指挥能力作出综合评价。
