Police Corruption: Towards a Working Definition

According to the International Committee of the Red Cross (ICRC) publication Interpretive Guidance on the Notion of Direct Participation in Hostilities under International Humanitarian Law, all civilians (including child soldiers) lose their immunity from direct targeting ‘for so long as’ their actions amount to direct participation in hostilities. All civilians can, however, access the revolving door of protection and return to their civilian activities – complete with full immunity from direct targeting – provided the nature of their direct participation was spontaneous and disorganised. Once it can be ascertained that their participation in hostilities amounts to continuous combative functions, they relinquish their access to the revolving door of protection, and can be targeted at all times until they abandon their formal or functional membership of the belligerent group. This piece analyses how the revolving door phenomenon and the notion of continuous combative functions apply in instances where civilian child soldiers are directly participating in hostilities.

On the median residual lifetime and its aging properties: A characterization theorem and applications

This paper is devoted to study several aspects of the median residual life function (MERLF). In reliability studies, it is well known that, although the MERLF have several advantages over the mean residual life function (MRLF), the MRLF has the good property of uniquely determine a life distribution whereas either the median residual life function (MERLF) or an α‐percentile residual life do not have such good property. We shall give a characterization result where knowledge of both the MERLF and the survival function on an interval does uniquely determine the distribution. Moreover, in order to apply this characterization in practical situations, we propose a method to estimate the necessary information of the survival function. Relationships between analytical properties of the survival function and its associated MERLF are also obtained. Bryson and Siddiqui [J Am Statist Assoc 64 (1969), 1472–1483] proved relationships among seven criteria for aging, out of which two contained the MRLF (decreasing MRLF and net decreasing MRLF). In this paper, we prove that the same pattern of relationships holds if the MRLF is replaced by the MERLF. We also examine the aging criteria corresponding to an increasing MERLF and show that there is no relation between the behavior (increasing or decreasing) of the MERLF and of the MRLF. © 2005 Wiley Periodicals, Inc.

Maximizing the ratio of two convex functions over a convex set

The purpose of this article is to present an algorithm for globally maximizing the ratio of two convex functions f and g over a convex set X. To our knowledge, this is the first algorithm to be proposed for globally solving this problem. The algorithm uses a branch and bound search to guarantee that a global optimal solution is found. While it does not require the functions f and g to be differentiable, it does require that subgradients of g can be calculated efficiently. The main computational effort of the algorithm involves solving a sequence of subproblems that can be solved by convex programming methods. When X is polyhedral, these subproblems can be solved by linear programming procedures. Because of these properties, the algorithm offers a potentially attractive means for globally maximizing ratios of convex functions over convex sets. © 2006 Wiley Periodicals, Inc.

引入权重因子的证据合成方法

D-S理论是一种有效的不确定性推理方法,但在证据完全冲突或冲突较大时,D-S证据合成公式失效.Yager等学者对此作了改进,但是改进后合成公式又存在着新的问题.考虑到证据在合成过程中的重要程度不同,将权重因子引入到合成公式中,通过权重因子的作用和冲突概率的重新分配,提出了引入权重因子的D-S证据合成方法,新的合成公式提高了证据合成的可靠性和合理性,可得到更为理想的合成结果.

【邀请论文】美军未来司令部探析——成立背景、主要职能与未来前景

新一轮科技革命的快速发展正推动战争形态从信息化向智能化演进。美军作为二战后始终位列世界第一的军事力量,正在积极设计未来战争以应对当前的“大国竞争”,2018年刚刚成立的陆军未来司令部正是在这一背景下产生的。未来司令部隶属于美国陆军,主要负责美陆军新型武器装备的研发、未来作战概念创新以及新兴军事科技的测试和应用。成立两年以来,未来司令部已经拥有了一套完善、严密的组织架构,创造了包括C5ISR作战概念在内的一系列理论成果,在空基导弹、远程精确火力系统等新型作战装备上也取得了众多进展。本文基于大量前沿文献研究,廓清了未来司令部的组织架构,总结了其主要职能,并对这一新设司令部的发展前景进行了展望和预测,期望能够为推进军队现代化和未来化建设提供有益启示。     

ISIS’s Warfare Functions: A Systematized Review of a Proto-state’s Conventional Conduct of Combat Operations

This article gives an overall assessment of ISIS’s conventional conduct of combat operations by examining their warfighting functions patterns. In sum, the approach of ISIS comprised fundamental principles: their weapons can be organized into categories, purposeful combination of these forces in keeping with the concept of combined arms combat, and hierarchical command and control executed by experienced commanders. ISIS combat groups combined the elements of formation and firepower as well as movement and mobility. The paper concludes that ISIS obviously had a vast range of conventional capabilities at its disposal and was thus able to conduct major operations.
