模糊数据的编码压缩

建立在普通集合之上的传统的数据压缩方法不能胜任模糊领域中的问题。因此,有必要从模糊集合理论出发,导出模糊概率的概念和模糊信息,赋予数据压缩理论和技术新的活力。本文试图从模糊理论的角度,借助于广义信息论,探讨模糊信息压缩的方法和意义。     

从建设和平的视角看联合匡维和行动的困境

联合国维和行动目前面临着日益严峻的困难和挑战。其中的一个重要原因在于维和人员被赋予了过多的建设和平的职责,使得维和行动处于两难的境地。要缓解这一困境,国际社会需重新审视和定义维和行动的职责范围,大力加强和平委员会的能力建设,并给予更多的授权。在实现这些长期目标之前,维和特派团将继续代替建和委履行建设和平协调员的职责。     

Rossellini,Pontecorvo, and the neorealist cinema of insurgency

This article examines the tradition of Italian neorealism and the importance it has for films depicting guerrilla insurgencies. It looks in particular at the two films by Roberto Rossellini Rome Open City and Paisa as well as the later film by Nanni Loy Four Days in Naples. It then proceeds to locate Gillo Pontecorvo's iconic film The Battle of Algiers within this neorealist tradition and examines the degree to which the director succeeded in continuing the basic traditions of neorealism into the context of the Algerian war of Independence. The article concludes that while this film remains of great interest it should be situated in the period when it was produced and is in many ways radically disconnected from many insurgent movements of the present day.     

Into the black box? Technology sharing in major arms transfers and beyond

From the recipients’ perspective, arms transfers have, through the use of offsets, technology transfers, and industrial participation, become an opportunity to receive not only advanced weapons, but also technologies not otherwise available. How important are friendly relations for securing a military export order? To what extent do buyers demand advanced military or commercial technology and how are these demands accepted by the supplier? How does this influence smaller producers in relation to major producers? These questions are addressed by studying (a) the Joint Strike Fighter/F-35 by Lockheed Martin, USA, and the JAS-39 Gripen aircraft by Saab, Sweden, (b) the Medium Multi-Role Combat Aircraft competition in India for 126 combat aircraft, and (c) the Indian offset policy. In the final section, some long-term consequences are discussed.     

Reforming the notion of national sovereignty by external intervention

In principle, national sovereignty is the right of a nation to govern its internal affairs without foreign interference. In practice, it is defined by one's interpretation of international law, which may permit legal external intervention under some circumstances, ultimately removing a nation's sovereignty. This paper will examine the current system of international law outlined by the United Nations, analyse the ambiguities contained within its Charter and elaborate on how external intervention can be justified. The case-study of recent developments related to Libya will demonstrate that the manner in which international law is interpreted is changing the notion of principles of sovereignty.     

COIN fights: A response to Etzioni

Etzioni both exaggerates and minimizes the influence of my book Learning to Eat Soup with a Knife on different components of US military doctrine, mischaracterizes my treatment of the Malayan Emergency, and unfairly denigrates the successes of counterinsurgency in Iraq from 2007 to 2011 while misattributing the reasons for its failures in both Iraq and Afghanistan.     

National security,military spending and the business cycle

This paper develops a Dynamic Stochastic General Equilibrium model where national security is an argument in the agent’s utility function and the government chooses optimally the level of military spending to maximize social welfare. National defense depends on military expenditure and on the strategic environment reflecting a potential hostile external threat. We use aggregate data on consumption, investment, and military spending for the US economy to estimate the parameters of the model. Estimation results suggest that consumption and national defense are complements and that military spending variability is mainly explained by external threat shocks although it also depends on the macroeconomic conditions. We compute impulse response functions of the main macroeconomic variables to several shocks: a total factor productivity shock, a defense technology shock, and a strategic environment shock. Surprisingly, we find that the optimal response to an increase in the external threat (a worsening in the strategic environment) will rise output by reducing consumption and increasing investment.     

舰炮火力系统智能结构分析

遵从“智能增加,精度降低”(IPDI)原则,将舰炮火力系统(含雷达、C~3I、舰炮等系统)的智能结构分为概念、协调、执行3级,并着重分析采用广义信息熵作为各级统一评价标准的可能性。最后,还简要提出了新型舰炮火力系统智能化发展的方向。     

联合国维和警察防暴队甄选考试改革对维和培训的影响及对策

2012年9月颁布的《联合国维和警察防暴队行动能力评估标准作业程序》对联合国防暴队甄选及行动能力评估的组织、实施程序、考查标准等方面都进行了较大的调整。从联合国维和警察防暴队甄选标准作业程序的改革入手,以考试为突破口和着眼点,研究程序的改革对维和警察防暴队培训的影响,制定应对策略,以时维和培训工作具有指导作用和借鉴意义。     

浅议维和警察团队构建及团队精神的培养

维和警察团队在维和行动中展现了强大的优势。在构建维和警察团队时,要把握好一系列原则;在培养其团队精神时,要做好以下六个方面的工作：强化维和事业心、合理明确的定位、警队制度化、复合化培养、以人为本、处理好警队内部竞争与合作的关系。
