The fertile ground of Hell’s carnival: Charles T. R. Bohannan and the US Army’s Counter Intelligence Corps’ investigations of war criminals,collaborators, and the Huk,in the Philippines 1945–1947

Insurgencies thrive in regions where government legitimacy is absent. In the post-war Philippines, Captain Charles T. R. Bohannan of the Army’s Counter Intelligence Corps became actively aware of this dynamic. Bohannan is best known for his later work with Edward Lansdale and Ramon Magsaysay in defeating the Huk Rebellion (1950–1954). Here the author examines Bohannan’s early investigative work against Japanese war criminals, wartime Filipino collaborators, and the rising threat of communist subversion most associated with the Huk. All of these experiences fed into what would be the successful campaign against the Huk, chronicled in his seminal work, Counter Guerrilla Operations: The Philippines Experience, and offers lessons on the investigative (as opposed to tactical or psychological) nature of effective counter-insurgency work, as it relates to both legitimacy in governance and the rise of insurgencies.

(Re-)emergent orders: understanding the negotiation(s) of rebel governance

Abstract

The concept of order is often neglected in the study of conflict – seemingly such a ‘disordering’ process. With the recent increase in the examination of rebel governance however, bringing order back into our understanding of rebel and insurgent groups has much to offer in exploring the everyday politics which connect authorities, rebel movements and the population itself, in a complex mass of intersubjective and power-based interactions and negotiations. Rebels both shape and are shaped by existing forms of order in complex and ongoing ways. This article explores how varying elements interact in the negotiation, framing and enforcement of order and develops an original analytical framework to examine the perpetual negotiations of rebel movements in their attempts to cement their control.     

一种Turbo码中伪随机交织器的盲识别方法

目前Turbo码的构造中广泛应用的是伪随机交织器,要完成对Turbo码的识别,必不可少地需要得到伪随机交织器的参数。针对伪随机交织器的识别问题,通过引入扩频通信中PN序列盲估计的方法,利用功率谱二次处理法求出交织长度即m序列周期,再用特征分解方法对序列进行估计。仿真实验表明,该方法能够求出m序列的相关参数,完成对伪随机交织器的识别需求。

基于核与灰度的区间灰数多属性群决策方法

针对属性值为区间灰数且专家权重未知、属性权重部分已知的不确定多属性群决策问题,提出了一种基于区间灰数的核和灰度的决策方法。给出了区间灰数的基于核和灰度的简化形式,充分利用区间灰数的核和灰度的信息建立优化模型求得属性的权重。在求出属性权重的基础上,运用灰色关联方法分别求取各专家的核与灰度距理想方案值的关联系数,综合两者得到专家权重,最终综合专家意见并对方案比较排序得出最优结果。鉴于此,提出一种基于区间灰数相对核与灰度的决策方法。最后以一个算例验证该方法的有效性和可行性。     

基于数据适应性检验的身管磨损量预测研究

应用灰色系统理论研究不确定系统,对系统进行灰色预测模型建立的同时,需要检验系统原始数据序列是否符合建模要求。主要从3个方面检验数据建模的可行性,分别是光滑比、极比偏差和凹凸性检验。结合某型坦克炮身管内膛烧蚀磨损数据,采用不同的磨损数据作为灰色预测模型建模的原始数据序列,具体分成两种情况进行数据检验,并代入模型计算,分析不同情况下模型的预测精度,通过对比计算结果选出与模型匹配度更高的原始数据序列。
