THE HUMAN CAPITAL PEACE: DEVELOPMENT AND INTERNATIONAL CONFLICT

This paper explores the relationship between human capital and international conflict. In theory, human capital may increase the opportunity cost of military service and the economic cost of injury and loss of life in combat; it may decrease the benefits of conflict as human capital cannot be easily appropriated or transferred; it may affect societal norms toward peace and war; and it may alter military productivity through new technology and complementarities between military technology and personnel. Using a panel of politically relevant dyads, I find robust empirical evidence that human capital may significantly decrease the likelihood of militarized conflict between nations. In short, the findings suggest that promoting human capital‐oriented development may help to increase peace in the world.     

Territorial contestation and repressive violence in civil war

This study models the structural sources of variation in the use of selective (discriminate) repression within 89 civil wars fought between 1981 and 2005. The severity of repressive violence is modeled as a function of the amount of territory being contested by the insurgents. This idea is operationalized using measures of the location, size, and density of insurgency violence. The analysis finds evidence that the repressive behavior of both governments and rebel groups is linked to conflict geography. Governments violate physical integrity rights more frequently and kill more civilians the greater the overall amount of territory under contestation. Rebels kill more civilians in highly dispersed insurgencies that lack a clear epicenter.

Cyber War is Inevitable (Unless We Build Security In)

The information systems controlling our critical infrastructure are vulnerable to cyber attack. Cyber war is therefore inevitable unless we improve our cyber defenses. The only way to do this is by building security into systems at the design stage.     

War as a System: A Three-Stage Model for the Development of Clausewitz’s Thinking on Military Conflict and Its Constraints

This article presents a new model for the development of Carl von Clausewitz’s thinking on the factors that constrain warfare. The model posits three stages in his thinking that are determined by two system theoretic dimensions. The three stages are friction as a constraint on the effectiveness of the execution of military plans on paper, suspension as a constraint on the intensity of military action and political objectives as a constraint on military objectives. The two dimensions consist of an interactive perspective in the form of causal feedback loops and a holistic perspective in the form of a political system that forms the context of the military subsystem.     

三维数据场的可视化

三维数据场是普遍存在的。本文给出一个三维标量场和矢量场的可视化方法：对计算或实测产生的离散数据重构三维连续场的分布,构造数据场的整体发光模型,并根据发光模型计算视屏投影区域上各象素点的光强值,采用直接体绘制（ｄｉｒｅｃｔｖｏｌｕｍｅｒｅｎｄｅｒｉｎｇ）及视觉增强处理绘制出场的可视化图象,通过特征面处理绘制出场的局部分布图象。图象层次及细节丰富,反映了场的分布信息。系统具有较强的交互功能,静态、动态显示功能及友好的用户界面。
