Country failure and social grievances in the Greek Civil War 1946–1949: An economic approach

The Civil War that took place in Greece between the Communist Party and the Centre-Right Government during 1946–1949 is examined from a political economy perspective. The cost of the conflict is measured as output forgone relative to what it would have prevailed had Greece followed a post-war recovery similar to that of other nations in Western Europe. A two-stage approach compares Nazi-occupied countries with neutral ones to assess the cost inflicted by Second World War, and then compares Greece with the former to estimate the impact of the civil conflict. A regional analysis finds that the political discontent was mainly shaped by pre-war socio-economic grievances, rather than being affected by contemporaneous deprivation or driven by class structure as hardliners of both sides preferred to present in pushing for an all-out confrontation. The failure to settle political rivalries and thus prevent the conflict is also discussed.     

A Territorial Conflict: Trade-offs and Strategies

We study a war scenario in which the winner occupies the loser’s territory. Attacking a territory increases the chance of winning, but also causes harm, which in turn decreases the territory’s value (i.e. the reward of winning). This paper highlights the effects of this trade-off on the equilibrium strategies of the warring states in a contest game with endogenous rewards. Providing both static and dynamic models, our analysis captures insights regarding strategic behavior in asymmetric contests with such conflict.

Asbestos in the collection of the Royal Armouries and the conservation of a First World War German gasmask

In March 2015, in order to comply with Health and Safety Regulations, the Royal Armouries contracted an external company to carry out an asbestos audit. This article looks at what that audit entailed and also how a gasmask suspected of containing asbestos, was made safe in order to conserve and display it.     

基于复杂网络的作战描述模型研究*

针对传统作战模型重点关注兵力的毁伤,不能充分地反映信息时代作战的特点,提出了一个基于复杂网络的作战描述模型,把作战单元抽象成节点,把各单元之间的相互作用抽象成有向边,将战场描述为一个由传感器、决策器、影响器、目标四类节点组成的有向网络图。定义了网络模型的若干特征参数,把作战环看成是反映作战能力的指标,并区别分析了标准作战环和广义作战环,能更好地反映信息时代作战的特点。最后实例研究了传统作战条件下决策器连通程度的变化给作战能力带来的影响。     

Approximations and empirics for stochastic war equations

The article develops a theorem which shows that the Lanchester linear war equations are not in general equal to the Kolmogorov linear war equations. The latter are time‐consuming to solve, and speed is important when a large number of simulations must be run to examine a large parameter space. Run times are provided, where time is a scarce factor in warfare. Four time efficient approximations are presented in the form of ordinary differential equations for the expected sizes and variances of each group, and the covariance, accounting for reinforcement and withdrawal of forces. The approximations are compared with “exact” Monte Carlo simulations and empirics from the WWII Ardennes campaign. The band spanned out by plus versus minus the incremented standard deviations captures some of the scatter in the empirics, but not all. With stochastically varying combat effectiveness coefficients, a substantial part of the scatter in the empirics is contained. The model is used to forecast possible futures. The implications of increasing the combat effectiveness coefficient governing the size of the Allied force, and injecting reinforcement to the German force during the Campaign, are evaluated, with variance assessments. © 2005 Wiley Periodicals, Inc.

基于网络的指挥控制协同性能评估模型

网络中心作战是通过部队网络化而实现的军事行动,网络化作战行动的评估需要新的模型和测量方法,以便获取基于信息优势对改进后的指挥和控制的效果.在借鉴美军经验的基础上,从信息的角度区分了网络中心作战信息栅格运作的方式,运用图论、复杂性理论和性能评估理论等方法,建立了作为信息处理系统的指挥控制网络的结构、预期延迟时间、协同影响、复杂性和有效期望等待时间模型,以及作为指挥控制系统的指挥控制网络的节点决策和网络决策效能模型,是对网络中心作战方法的探索.     

Shifting power,preventive logic,and the response of the target: Germany,Russia, and the First World War

If a declining state has incentives for preventive war, the rising state should have incentives to delay a confrontation until it is stronger. We develop the theoretical paradox and examine the July 1914 crisis. Why did Russia, rising relative to Germany, not adopt a buying-time strategy? We argue that although most Russian leaders hoped to avoid a confrontation, they feared that the failure to support Serbia would lead to a loss of Russian credibility and a significant setback to Russia’s position in the Balkans, one that could not easily be reversed, even with Russia’s expected increase in relative military power.     

Size Still Matters: Explaining Sri Lanka’s Counterinsurgency Victory over the Tamil Tigers

The military effectiveness literature has largely dismissed the role of material preponderance in favor of strategic interaction theories. The study of counterinsurgency, in which incumbent victory is increasingly rare despite material superiority, has also turned to other strategic dynamics explanations like force employment, leadership, and insurgent/adversary attributes. Challenging these two trends, this paper contends that even in cases of counterinsurgency, material preponderance remains an essential—and at times the most important—factor in explaining battlefield outcomes and effectiveness. To test this, the paper turns to the case of the Sri Lankan state’s fight against the Tamil Tiger insurgency, a conflict which offers rich variation over time across six periods and over 25 years. Drawing on evidence from historical and journalistic accounts, interviews, memoirs, and field research, the paper demonstrates that material preponderance accounts for variation in military effectiveness and campaign outcomes (including military victory in the final campaign) better than strategic explanations. Additionally, a new quantitative data-set assembled on annual loss-exchange ratios demonstrates the superiority of materialist explanations above those of skill, human capital, and regime type.
