Lessons in airpower projection: Indochina and Algeria

The lessons from the two French counterinsurgencies, Indochina and Algeria, give rise to a new understanding of the projection of airpower in remote and hostile environments and the purpose, design, and use of aircraft in counterinsurgency. In both Indochina and Algeria, the campaigns were ones of poverty, and it is their imaginative management under severe resource constraints that provides thoughtful and applicable lessons for today. In both cases, airpower held the promise of delivering victory and solving the resource issue. In Indochina, acquisition of the needed aircraft, operating knowledge, and experience came too slowly to realize this promise. In Algeria, the French embraced the lessons from Indochina and were quite successful and innovative in the use of airpower. The lessons can be reduced to four requirements: (1) a network of airfields for liaison, ground-support, and intra-theater airlift to enable effective air support of ground forces; (2) a solid, reliable, and simple ground-support aircraft capable of operating from forward airfields within range of ground engagements; (3) a capable intra-theater heavy-lift transport to supply the extended ground forces; and (4) helicopter capability to enhance tactical troop mobility and support.

基于DoDAF的装备体系结构建模方法

美军DoDAF体系结构框架是一种重要的武器装备体系建模标准,对于保证武器装备系统之间可集成性、可互操作性具有重要的借鉴意义。为支撑武器装备体系建设的统一建模过程,优化体系结构和控制变更影响,文章力图在“能力需求牵引”作战思想指导下．提出基于DoDAF标准的结构化武器装备体系结构建模方法。采用DoDAF基线产品与用户自定义产品（基于“适用”原则）相结合的方式,从建模框架、流程、方法和支撑产品等方面对武器装备体系结构建模方法进行系统研究。由于使用结构化建模方式,在建模过程中采用与开发了相关的基础建模产品,从而使得模型更具针对性,建模过程更加直观、具体和易于操作。     

Dynamic Winner-Take-All Conflict

This paper empirically investigates the importance of financial and political variables in determining debt rescheduling probabilities in Turkey for 1955–2000. The problem of sovereign debt default and rescheduling has been the subject of substantial academic research during the last two decades. There has been criticism of models of developing countries’ indebtedness and rescheduling that rely solely on some economic or financial predictors related to country debt, the foreign exchange sector or the domestic economic situation. Using probit analysis, this paper indicates that financial variables are important determinants of rescheduling probabilities. However, political variables are not significant in our models.     

Transnational terrorism as a spillover of domestic disputes in other countries

This paper models transnational terrorism as a three‐way strategic interaction involving a government that faces armed opposition at home, which may spill over in the form of acts of terrorism by the state's opponents against the government's external sponsor. The external sponsor also utilises deterrence against potential terrorists, which only lowers terrorism if terrorists are not intrinsically motivated by a deep‐seated sense of humiliation. The model highlights the importance of intrinsic motivation. A rise in the external power's preference for deterrence against terrorism may backfire in these circumstances. Increases in the government's military efficiency against the rebels, who are also terrorists against the government's sponsor, raises overall levels of violence.     

Defence Enterprise Surveys On Market Outlets: The Case Of Slovenia

This article presents the results of an empirical survey of Slovenian defence enterprises focusing on three segmented geographic market outlets: the domestic market, the other European Union (EU-26) markets and the global markets. In the enterprise surveys are included around two-thirds of the domestic defence enterprises of different sizes and activities. The Slovenian defence enterprises by production, supply-in-return, subcontracting, middleman and trader activities in the defence marketing chains are mostly specializing towards the businesses on the domestic market. Rare enterprises are specialized exclusively for activities on the EU-26 markets and the global markets.

GNSS多系统联合的探月飞行器轨道定位分析*

为适应深空探测的应用需求,全球卫星导航系统对深空飞行器定位的可行性问题备受关注。针对探月飞行器月球公转轨道上的GNSS定位问题,以高轨道飞行器GNSS定位的研究为基础,采用多系统联合定位的方法进行仿真。分析了载波功率与噪声功率密度比为15dB-Hz的弱信号捕获门限下,各系统联合定位时波束主瓣和旁瓣的可用性,同时对各系统联合情况下的精度因子值进行分析。仿真结果表明：当接收到的卫星天线辐射的主瓣和旁瓣信号均高于载噪比门限时,全球卫星导航系统的三系统或四系统的联合能满足实时定位条件;而旁瓣损耗不加以补偿时,接收信号载噪比低于门限并导致任意联合方式均无法完成定位。各系统联合的精度因子分析表明：单系统或双系统联合的几何精度因子变化剧烈,四系统联合相比三系统联合的几何精度因子下降16.93%;三系统联合定位方案中,美国全球定位系统、中国的北斗卫星导航定位系统与欧洲的伽利略卫星导航定位系统联合方案的几何精度因子值变化最平稳,为最佳选择。理论分析和仿真结果为探月飞行器定位技术研究和星载多系统接收机设计提供参考。
