On gamma estimation via matrix kriging

In financial engineering, sensitivities of derivative prices (also known as the Greeks) are important quantities in risk management, and stochastic gradient estimation methods are used to estimate them given the market parameters. In practice, the surface (function) of the Greeks with respect to the underlying parameters is much more desired, because it can be used in real‐time risk management. In this paper, we consider derivatives with multiple underlying assets, and propose three stochastic kriging‐based methods, the element‐by‐element, the importance mapping, and the Cholesky decomposition, to fit the surface of the gamma matrix that can fulfill the time constraint and the precision requirement in real‐time risk management. Numerical experiments are provided to illustrate the effectiveness of the proposed methods.     

Killing Your Own: Confronting Desertion and Cowardice in the British Army During the Two World Wars

Military units can become to some extent self-governing in war-time battle. At times, they may take the discipline of their soldiers into their own hands and such discipline may be severe. This paper examines incidents in the British military, in both World Wars, where British soldiers were killed by their comrades because they would not fight in the heat of battle. The judicial execution by the military authorities of deserters in the First World War led to much controversy in Britain. It may be much less well-known that in both World Wars there was, on occasion, an extra-judicial practice within the British military of executing soldiers who would not fight in the heat of battle. In such situations ethical dilemmas become very difficult indeed and some of the relevant issues are examined here.     

A conceptual framework for the analysis of civil-military relations and intelligence

ABSTRACT

The article argues that current conceptual approaches in civil-military relations are deeply flawed resulting in its irrelevance in analyzing major issues including war and the collapse of democracy. After highlighting major flaws in the work of the late Samuel Huntington and those who follow his approach, the article argues that other conceptual approaches, including Security Sector Reform, are also flawed, or in the case of the “military effectiveness” literature, largely irrelevant. In explaining the main causes of the flawed conceptual literature, the article highlights the absence of good data and challenges in methodology. While arguing that military forces are very unlikely to engage in armed combat, it highlights the roles and missions which in the world today are implanted by these forces. As it is virtually impossible to prove effectiveness of the armed forces in these roles and missions, the article proposes a conceptual approach based on requirements.     

Vicarious warfare: The counterproductive consequences of modern American military practice

This article examines contemporary modes of American warfare. It posits the concept of “vicarious warfare” as a means of capturing prominent patterns in warfighting approaches. Although rooted in long-standing traditions of military practice, vicarious warfare is sufficiently novel as to be identifiable as a distinct phenomenon. The precise manifestation or combination of vicarious methods vary according to the specific circumstances and political contexts prevailing in different theaters. However, America’s general preference is to fight its wars by delegating tasks to proxies and limiting exposure of its own military to danger. Where U.S. forces are employed directly, this takes place largely in the shadows. Such approaches have clear attractions, offer undoubted tactical advantages, and permit successive administrations to maintain a persistent tempo of operations that evades rigorous democratic scrutiny. Yet, prominent cases and numerous studies suggest that vicarious warfare has a high potential to generate counterproductive effects and significant strategic harm.     

关于军民融合大交通体系建设的几点思考

党的十九大报告把军民融合发展战略作为七大国家战略之一,明确提出要"更加注重军民融合"。必须将交通领域军民融合视作整个军民融合深度发展的重要突破口,建设军民融合大交通体系。提出以新形势下军事战略方针为统揽,以军民深度融合为途径,聚焦保障军队打赢,大力推进民用交通设施工具贯彻要求;依托国家路网基础,大力推进军地交通运输网络统筹纳入;强化应战应急一体,大力推进各种交通力量建设互补衔接;着眼战略投送能力,大力推进军民交通物流体系有机结合。
