Counterinsurgency force ratio: strategic utility or nominal necessity

As a consequence of intervention in Iraq and Afghanistan, force ratio for counterinsurgency (COIN) has come under increased scrutiny. Reduced to its essence, the issue is simply, ‘How many troops does it take to get the job done?’ This answer has been sought by the US military, academia, and think tanks. There have been numerous responses, culminating in several ‘plug-and-play’ equations for minimum force ratios in COIN operations. Due to the impossibility of determining precisely how many insurgent forces there are, it has become common to base force ratios on the population of the country. In the realm of policy, the question above is posed as, ‘How many of our troops does it take to get the job done?’

Critics gone wild: Counterinsurgency as the root of all evil

The Western interventions in Iraq and Afghanistan have produced a heated polemic concerning the merits and demerits of counterinsurgency – the operational approach underpinning both campaigns. The two books reviewed here provide a good summation of the arguments against counterinsurgency: it is not a strategy and will fail when mistaken as such; its theory does not make intervention and war significantly easier; and even the most successful counterinsurgency campaigns have been bloody, violent, and protracted. Yet as this review highlights, beyond these central points, criticism of counterinsurgency is too often off the mark in its approach and totalizing in its pretentions. There is much to criticize and an urgent need to learn from past campaigns, yet bold claims and broad generalizations can mislead rather than enlighten. The analysis is particularly unhelpful when the definition of the central issue at hand – counterinsurgency – is being unwittingly or deliberately distorted. In the end, these two books form a poor basis for the debate that must now take place, because they are too ideological in tone, too undisciplined in approach, and therefore too unqualified in what they finally say.     

基于改进C-均值聚类算法的空中目标分类

空中目标的正确分类对防空作战效果有着重要的影响。在分析了空中目标类型和目标的表征方法之后,构建了动态聚类中的一种分类算法———改进C-均值算法。该算法改变了以前算法中只用一个聚类中心作为一类的代表的做法,而采用的是类核函数代替类心的方法。类核函数较一个聚类中心更能够表现出某一类的分布信息,从而提高分类的正确率。

论校园文化建设的思想与实践——基于华山中学校园文化建设活动的系列思考之三

以马克思主义文化观为指导,在对校园文化建设进行科学规划和实施的过程中,必须首先确立校园文化建设的主题。校园文化建设的主题要反映学校自身的发展需要,也要表现学校自身的精神追求,还要呈现学校自身的文化特点。华山中学的校园文化建设紧紧围绕这三个方面进行构思,提出了"胡杨文化"和"胡杨精神"的概念,将其作为校园文化建设的主题目标,据此展开了一系列的文化设计和表达,并对"兵团精神"做出了独特诠释,使校园文化建设落到了实处,特色鲜明,效果显著。
