The UK defence electronics industry: adjusting to change

The electronics industry provides components and capabilities that are critical to modern defence requirements. It is anticipated that the effectiveness of both weapons systems and the command and control network that supports military operations will become increasingly dependent upon the electronics sub‐systems they employ in the future. With the ascendancy of ‘network centric warfare’, it seems certain that defence electronics will continue to grow in importance in the future, enabling far‐reaching advances in military capability and efficiency. Yet little is known about the structure, conduct, performance and competitiveness of the UK defence electronics sector as it prepares to meet the challenges ahead. This paper reports the findings of a study commissioned in 2002 by Intellect, the UK defence electronics trade association, and supported by the Department of Trade and Industry. The UK defence electronics industry is found to be a high technology, R&D‐intensive and decreasing cost industry, which is competitive in world defence markets. The UK industry faces major competitive threats in the future from established US and European firms and from potential new entrants from China, India, Israel, Singapore, South Korea and Turkey. The future competitiveness of the UK defence electronics industry will depend on maintaining both technical advantage and open access to the large US market.     

At war with social theory: Instrumental and communicative action in US military doctrine during the War on Terror

As US counterinsurgency campaigns draw to a close, doctrine for asymmetric warfare written during the War on Terror has come under heavy criticism. While many have argued that this shift to ‘winning hearts and minds’ is evidence that the United States is taking humanitarianism and nation-building seriously, others argue that a wide gap exists between US counterinsurgency doctrine and the protection of civilians afflicted by conflict. In this article, I show that the latter is true by comparing theories of instrumental and communicative action to US doctrine for operational design, stability operations, and counterinsurgency. I argue that these texts treat the people as an object to be manipulated for the achievement of pre-determined self-interested strategic goals rather than members of a community that jointly designs operations to fulfill shared objectives. However, US doctrine does contain communicative elements that, if prioritized, would better support humanitarian and state-building objectives otherwise subordinated in the War on Terror.     

贝叶斯网络在潜艇远航隐蔽性评估中的应用

针对潜艇远航中面临探潜兵力种类多、各兵力间相互联系的特点,将基于贝叶斯网络的故障诊断方法引入到潜艇隐蔽性的评估中。假设通过分析某次远航实例后得到节点分布参数,结合建立的潜艇远航暴露贝叶斯网络图,得出相关结论。初步探讨了该方法对潜艇隐蔽性的评估、诊断暴露原因、确定关键探潜兵力等方面的应用价值。     

基于ANP的多目标网络目标重要度评估方法

摘　要：目标重要度分析是军事计划人员开发作战计划方案的前提和基础,是形成作战行动的基本依据。针对多目标网络中重心的抽象性及不易打击的特点,分析影响重心的关键要素及其依赖关系,提出了基于改进网络分析法的多目标网络重心模型,利用该模型分析目标相对于重心的重要度。研究了该模型涉及的两个关键技术,即改进判断矩阵以提高决策的速度和克服决策的主观性,利用协调理论确定要素之间的依赖关系。以分析某地区多目标网络的过程为例,验证了该模型的有效性和合理性。     

Drones,spies, terrorists,and second-class citizenship in Pakistan

This essay reviews seven recent books and reports that focus upon the use of US armed drones in Pakistan's Federally Administered Tribal Areas (FATA). This essay synthesizes a historical account of the program, critically interrogates key arguments and evidence advanced by the authors, and draws attention the particular problems that confront those who live in the FATA and the second-class citizenship that the Pakistani state has bestowed upon them for reasons of domestic and foreign policy concerns. This review essay does not intend to be the final word on any of the ongoing policy debates. But it does hope to enable a wider audience to take part in these important deliberations.     

浅谈网络时代传统期刊的出路

编辑出版工作是各种知识信息传播的重要环节之一,是学术、科研成果得以展示和交流的有效途径。当前,互联网的强大功能极大地改变了信息传播形式和形势。但是,互联网毕竟只是一个信息交换场所,它无法真正替代传统期刊编辑出版的作用。不能把网络时代对期刊信息的使用与编辑出版混为一谈。
