对恐怖活动成因的深层透析

恐怖活动是困扰当今世界和平的大敌，其发生有许多表层或直接诱因。深入分析当今世界的经济体系和社会政治体制可以发现，一个国家或地区的经济发展不平衡、对社会资源的获取不平衡。是恐怖活动发生的深层根源。由此可见，根除恐怖活动的根本途径在于加强社会的和谐与协调发展。     

The building evacuation problem with shared information

In this article, the Building Evacuation Problem with Shared Information (BEPSI) is formulated as a mixed integer linear program, where the objective is to determine the set of routes along which to send evacuees (supply) from multiple locations throughout a building (sources) to the exits (sinks) such that the total time until all evacuees reach the exits is minimized. The formulation explicitly incorporates the constraints of shared information in providing online instructions to evacuees, ensuring that evacuees departing from an intermediate or source location at a mutual point in time receive common instructions. Arc travel time and capacity, as well as supply at the nodes, are permitted to vary with time and capacity is assumed to be recaptured over time. The BEPSI is shown to be NP‐hard. An exact technique based on Benders decomposition is proposed for its solution. Computational results from numerical experiments on a real‐world network representing a four‐story building are given. Results of experiments employing Benders cuts generated in solving a given problem instance as initial cuts in addressing an updated problem instance are also provided. © 2008 Wiley Periodicals, Inc.

群体性事件参与者的社会心理特征探析

现阶段我国群体性事件逐渐成为影响社会稳定的重要问题.群体性事件参与者普遍的失衡心理、自认为行为＂合理＂的片面心理、侥幸投机心理和易受感染的从众心理是酿成群体性事件的重要社会心理特征.加强心理疏导是预防和处置群体性事件的重要措施之一.

(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.     

Bernard Fall and Vietnamese Revolutionary Warfare in Indochina

This article assesses Bernard Fall’s concept of Vietnamese Revolutionary Warfare in Indochina between 1953 and 1958. It also investigates differences in the conceptualization of Revolutionary Warfare between Fall and proponents of French military doctrine known as la guerre révolutionnaire. The last component of the article considers limits of Fall’s influence on counterinsurgency doctrine.     

基于自然连通度的复杂网络节点重要性度量方法

节点重要性度量是复杂网络研究中的热点问题。从复杂网络的抗毁性指标入手,给出了自然连通度的定义,并且以此为基础设计了基于自然连通度的复杂网络节点重要性度量方法。最后以著名的风筝网络为例,分析了该方法的适用性,并与其他经典的节点重要性度量方法进行对比,证明了该方法的合理性。     

基于介数中心性重要节点的能量均衡机制

针对无线传感器网络中瓶颈节点和准瓶颈节点对网络影响的特例性问题,将重要节点的概念推广到对节点介数的研究,提出了基于介数中心性重要节点的能量均衡机制。该机制将介数值大于网络平均介数值的节点判定为重要节点,并利用重要节点的邻居节点建立缓冲机制来减少其数据的转发次数,在牺牲较少数据传输延时的情况下节省了介数中心性重要节点的能量消耗。仿真实验表明该机制能够较好地均衡无线传感器网络中的节点能耗,提高了网络生命周期。
