基于复杂网络理论的C2组织网络拓扑结构研究

根据C 2组织结构的特点,基于复杂网络理论和网络中心战思想,将C 2组织中的各作战单元、指控节点等作为节点,它们之间的信息流动作为边,构建C 2组织的网络拓扑结构。经过仿真分析,推出其内部具有无标度性、小世界性等复杂网络特性,这对于进一步将复杂网络理论应用于C 2组织的研究提供了理论依据并具有积极的意义。     

浅谈中小户型住宅的空间可变性设计

中小户型住宅受建筑面积的限制,套内使用空间相对较少,因此充分发挥有限空间的作用,提高空间利用率是中小户型住宅具有较高舒适性的关键。空间的可变性设计正是以满足居住者的多种需求变化、充分利用空间为目标的设计方式,它对于提高人们的居住质量、促进住宅的可持续发展具有积极意义。从社会、经济、生活等方面阐述了中小户型住宅空间可变性设计的必要性,并通过设计实例的分析,提出从住宅的空间设计、结构设计、厨卫空间设计三方面入手来实现空间的可变。

The dangerous myths and dubious promise of COIN

Counterinsurgency (COIN) has again emerged as a topic of both contemporary and historical interest in the age of what has been called a global counterinsurgency. However, little attention is being paid to the historical lineage of a COIN doctrine that is being rediscovered and promoted by an enthusiastic group of military intellectuals and commanders as the basis for US Army and Marine Corps doctrine. This article argues that historical claims for COIN success, based on courting popular gratitude by improving economic conditions, are at best anchored in selective historical memory, when not fantasy fabrications. The first argument of this article is that COIN does not constitute a distinct form of warfare, but merely a sub-set of minor tactics. Second, ‘hearts and minds’, so-called population-centric warfare, has seldom been a recipe for lasting stability. Rather, historically counterinsurgency succeeded when it has shattered and divided societies by severely disrupting civilian life. In fact, COIN is a nineteenth century legacy of empire whose uniqueness and impact was mythologized in its own day, and that is unlikely to prove a formula for strategic success in the twenty-first century.

The German wars of liberation 1807–1815: The restrained insurgency

In the Age of Napoleon, ‘small wars’ and ‘revolutionary war’ were closely connected. There were, however, different strands of this phenomenon: speaking professionally, conservative officers condemned small wars as an irregular regression to previous less disciplined forms of warfare. The Prussian state continually tried to discipline and regulate spontaneous risings. Yet the irregular character of small wars offered the opportunities for a less complex way of fighting, thus enabling the arming of the ‘people’ to fight. Individual undertakings, such as Ferdinand von Schill's doomed campaign in 1809, were designed to spark off a general popular uprising. But they were cheered by many and supported by few. Meanwhile, Neidhardt von Gneisenau conceived guerrilla-style Landsturm home-defence forces, which were designed for an irregular people's war. These concepts were put into practice in the ‘war of freedom’ – or ‘war of liberation’ – in 1813. Eventually both the mobilisation and the tactics remained regular, however, despite the emphatic appeal to a national ‘people's war’.
