THE GEOGRAPHY OF NUCLEAR PROLIFERATION NETWORKS

This article uses a geographic approach to examine one aspect of the nuclear black market: the coordinators who bring buyers and sellers together, and transport goods between them. The most important factor in determining the geographical structure of a proliferation network is the network coordinator's access (or lack thereof) to unique state resources. Coordinators with access to state resources and prerogatives can avoid embedding themselves in hostile countries or relying on commercial infrastructure, often leading to territorially diffuse logistical networks. Coordinators without such access are forced to rely on commercial infrastructure and favorable local political, economic, and social conditions, often resulting in territorially centralized logistical networks. This is illustrated through case studies of Abdul Qadeer Khan's supply networks to Pakistan, Libya, and Iran. The article concludes with some observations about the implications of a geographical approach for understanding nuclear proliferation networks.     

Dundee-made harpoon gun associated with H. M. S. Challenger

Attention is drawn to the existence of a harpoon-gun putatively from H. M. S. Challenger, a ship whose three-and-a-half-year circumnavigation of the globe (1872–1876), marked the beginning of the science of oceanography. The harpoon gun in question was made by Dundee shipsmith and harpoon-gun maker, David Neave. Only a few other examples of his work are known to exist and this example with a Remington rolling-block action is unusual for a British harpoon gun. It is proposed that it came to Millport's Marine Station via links Sir John Murray (1841–1914) had with the Marine Biological Association of the West of Scotland.     

New Light on the Swordmakers,Goldsmiths and Jewellers,John Ray and James Montague,Active in Partnership in London 1800–1821, With a New and Extended List of Their Known Work

Abstract

Some new information is presented on the prominent London goldsmiths and jewellers, John Ray and James Montague, of 22 Denmark Street, Soho, active in partnership from 1800 to 1821. A revised and extended list has been compiled of recorded works, including presentation swords, freedom boxes, ‘Toys’, tokens and other items, made by this highly reputable Soho workshop, during a decisive period of British history.     

美国2014年《四年防务评估报告》特点

2014年3月4日,美国国防部向国会提交了2014年版《四年防务评估报告》和《2015财年国防预算报告》。《四年防务评估报告》更新了再平衡战略,为美军建设提出了优先发展方向,要求美军联合部队向“更小型化”转型,以满足未来军事行动需求。     

美国网络霸权对中国国家安全的影响及对策

随着互联网对现实世界的影响越来越大,战略地位越来越突出,获得网络主导权、占据网络制高点成为各国竞相努力的目标。美国在全球网络管理、网络技术、网络文化、网络军事等方面处于霸主地位。美国网络霸权对中国的政治安全、信息安全、文化安全、军事安全造成了极大的威胁。中国应综合采取各种措施,应对美国网络霸权的冲击和挑战,维护国家安全和利益。     

海上机动目标打击效果评估决策支持系统设计

针对海上机动目标打击效果评估的特点,运用遥感技术、人工智能技术和模糊评判的方法探索打击效果评估问题。提出一种基于高分辨率遥感图像的打击效果评估决策支持系统,融合人定性分析和机器定量分析的优点,核心是问题处理系统综合运用处理后的遥感信息和支持系统的模型、知识以及数据来评估打击效果,评估模型为二级综合评判模型。对尚处于理论研究阶段的海上机动目标打击效果评估问题有积极的参考意义。     

信息化炮兵信息对抗能力综合评估方法

信息化战争使炮兵信息对抗对整个炮兵作战能力的发挥影响甚大。为科学评估炮兵信息对抗能力,对其信息对抗能力体系进行全面的分析,建立了评估指标体系;并利用模糊评定和层次分析相结合的方法,建立了炮兵信息对抗能力综合评估模型,从而为综合评估炮兵信息对抗能力提供了一种有效方法。     

线性调频脉冲压缩雷达的匹配干扰研究

由于脉冲压缩雷达对目标回波具有很高的压缩比(增益),而对不匹配的干扰信号则压缩比很小.为了提高干扰的有效功率,提出一种与脉压雷达目标信号相仿的线性调频信号作为干扰信号(即匹配干扰),经过理论分析得到了匹配干扰信号在不同的对准频偏情况下,进入雷达的有效干扰功率.通过仿真,结果证实这种匹配干扰可很大程度地提高进入雷达的有效干扰功率,但有效干扰功率会随对准频偏的加大而减小.     

资本主义之源:奢侈抑或禁欲——桑巴特与韦伯

桑巴特的资本主义起源假说在其《奢侈与资本主义》中得到充分展开。桑巴特认为,正是欧洲的奢侈之风生发出现代资本主义,而奢风蔓延又得益于非法爱情的盛行。相反,韦伯则认为现代资本主义源生于新教伦理中的禁欲主义。看似截然二分的两道命题,实则遵循同一思想路径。源自欧洲局部经验的理论抽象,虽不能释疑世界它处为何没有生发出资本主义的世纪性难题,但是对发展之道却不无借鉴意义。     

The art of net assessment and uncovering foreign military innovations: Learning from Andrew W. Marshall’s legacy

ABSTRACT

Andrew W. Marshall, who shaped the way in which contemporary international security experts think about strategy, has been mostly associated with the invention of net assessment. The intellectual sources of this analytical technique, and of the related competitive strategies concept, could be traced to Marshall’s efforts to uncover Soviet post-World War II defense transformations. This article outlines the essence of these Soviet innovations – the empirical frame of reference that inspired Marshall. It provides a new perspective on the history of the net-assessment methodology, advances the debate within strategic studies over the nature of military innovations, and offers insights for experts examining defense transformations worldwide.
