‘Winston has gone mad’: Churchill,the British Admiralty,and the Rise of Japanese Naval Power

As Chancellor of the Exchequer during the late 1920s, Winston Churchill was at the center of British strategic decision making about how to respond to the naval challenge posed by Japan's rise as a rival sea power. Churchill downplayed the likelihood of war with Japan. The leadership of the Royal Navy disagreed: they saw Japan as a dangerous threat to the security of the British Empire. Examining this dispute between Churchill and the Admiralty highlights the awkward political, economic, and strategic tradeoffs confronting British leaders between the world wars.     

A lost work of El Lobo: Lieutenant-Colonel Charles T.R. Bohannan's unpublished study of guerrilla warfare and counterinsurgency in the Philippines, 1899–1955

Charles Ted Rutledge Bohannan (1914–1982) became an integral agent of US counterinsurgency operations during the early Cold War, contributing to both the success of the COIN effort to defeat the communist Huk insurgents in the Philippines and the stalled COIN efforts in Vietnam. In the early 1960s, he wrote a short and compact analysis of the US and Filipino experience of guerrilla warfare, from the Philippine–American war until the defeat of the Huk Rebellion. It was never published. Reprinted here, Bohannan's analysis of lessons learned makes a substantial contribution to the history of American ideas of unconventional warfare by an expert who contributed these lessons to the successful defeat of an insurgency in South East Asia.     

基于多信号模型的计量策略设计与验证

装备可计量性的理论方法研究对提高装备的计量保障水平具有重要意义。针对国内缺乏装备可计量性模型的现状,提出了可计量性分析设计的多信号模型方法。系统总结了可计量性多信号模型的基本理论,详细介绍了在单超差假设及不考虑组元可靠性、计量时间和费用影响下的超差检查用检定和超差定位用检定操作优选算法以及计量策略制定方法。建立了信号产生系统多信号模型,给出了超差-检定相关性矩阵,分析了信号产生系统的计量检定树,结论与信号产生系统实际检定方法相符,实例证明,此方法合理有效。

Comprehensive Prohibition of Nuclear Weapons: An Emerging International Norm?

ABSTRACT

There have been calls for the abolition of nuclear weapons from the day they were invented. Over the last fifteen years, some indications can be found that such calls have been getting louder, among them Barack Obama's famous 2009 speech in Prague. In this article, we investigate if support for a comprehensive norm that would prohibit development, possession, and use of nuclear weapons is really growing. To assess the current status of that norm, we use the model of a “norm life cycle,” developed by Martha Finnemore and Kathryn Sikkink. We then analyze 6,545 diplomatic statements from the review process of the Treaty on the Non-Proliferation of Nuclear Weapons as well as from the UN General Assembly First Committee on Disarmament and International Security, covering the years 2000 to 2013. The evidence shows that a comprehensive prohibition can be considered an emerging international norm that finds growing support among states without nuclear weapons and nuclear weapon states alike. Only a core group of states invoke the norm consistently, however. This leads us to conclude that the “tipping point” of the life cycle, at which adherence to a new norm starts to spread rapidly, has yet to be reached.     

ZERO NUCLEAR WEAPONS

The current nuclear nonproliferation order is no longer sustainable. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) has weakened considerably over the years, with nuclear have-nots displaying increased dissatisfaction with the status quo. Meanwhile, demands for civilian nuclear technology have led to increased proliferation risks in the form of dual-use technologies. Arms control as we currently understand it—piecemeal treaties and agreements—is no longer sufficient to address the growing threat of proliferation and the frailty of the NPT. This article calls for a bolder nonproliferation agenda pursuing multilateral nuclear disarmament. Disarmament is, in fact, technologically achievable; a lack of political will stands as the only remaining roadblock to a world free of nuclear weapons. A better understanding of the technological feasibility of disarmament, as well as recognition of the diminishing strategic value of nuclear weapons, will help to erode this political reluctance.     

MAKING THE AGENDA STICK Lessons Learned From the 2007 NPT PrepCom

After the conclusion of the 2008 Preparatory Committee (PrepCom) for the 2010 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Nonproliferation Review interviewed Ambassador Yukiya Amano of Japan, who presided over the 2007 session of the PrepCom in Vienna. He provided valuable insights into his preparations for the PrepCom and shared his thoughts on some of the most pressing issues that confronted his chairmanship and the PrepCom as a whole. The interview also provides useful perspectives on the future of the strengthened review process.     

装药长径比对EFP成型作用效果影响分析

针对装药长径比对EFP成型的影响,基于一种球缺型药型罩EFP,利用ANSYS／LS-DYNA仿真软件对其成型过程进行建模仿真,研究EFP成型过程及其各项参数．在该基础上,改变装药高度得到不同的装药长径比数据,并对不同长径比EFP形成过程进行仿真,得到不同装药长径比EFP的速度、速度增长率及炸药能量利用率等数据,为选择最佳装药长径比提供依据．
