从应急管理理念、应急力量整合、应急法律制度和应对计划、社会参与、应急资源保障、人才培养体系、应急组织机构、联合应急方式等八个方面归纳总结了发达国家应急管理的共同特点,从突发公共事件应急组织体系、应急管理模式、整合信息资源、联合应急方式、应急保障、纲领性的公共突发事件应急管理基本法和应急计划等六个方面分析了我国突发公共事件应急管理方面存在的不足,并提出了改进的措施。     

恐怖活动中公众心理恐惧效应对社会稳定的影响及对策

恐怖活动往往导致公众的巨大心理恐惧效应,极易造成一定程度甚至是大规模的社会恐慌,严重影响社会稳定。因此,降低公众对恐怖袭击活动的心理恐惧效应、提高其心理承受能力,对恐怖活动发生时维护社会稳定具有重要意义。     

基于高阶累积量与神经网络的干扰识别算法

研究了一种基于高阶累积量和神经网络的干扰识别算法。该方法把卫星通信中常见的各种干扰信号的归一化高阶累积量作为分类特征参数,应用神经网络对特征参数进行分类训练,将接收干扰信号的归一化高阶累积量输入已训练的神经网络进行干扰类型的识别。试验结果表明:该算法在低干信比的情况下具有较高的识别准确率。     

Recognizing Fragmented Authority: Towards a post-Westphalian Security Order in Iraq

Abstract

The rollback of Daesh’s territorial control during 2017 has (re-)established an area of limited statehood in large parts of Iraq that may endure for many years. The government of Iraq projects its authority into a large geographical and political space that it shares with a multitude of other state, non-state and hybrid actors, competing and collaborating to achieve advantageous security and political outcomes. This paper examines the heterarchy of actors in post-Daesh Iraq to develop a typology and start a critical discussion about post-Westphalian alternatives for security governance in Iraq during the coming period of reconstruction and reconciliation.     

基于Citespace的国内公共政策研究现状分析

推进社会经济发展和管理需要科学制定和实施公共政策对当前研究现状进行分析梳理,有利于该领域的发展,使公共政策的制定和执行更加科学有效。以CNKI数据库收录的5799篇国内公共政策研究期刊论文为样本,采用文献计量法和知识可视化分析工具CiteSpace,对国内公共政策研究的现状、演进与热点等进行深入探讨。结果表明,21世纪以来,公共政策研究进入了高潮,但作者、机构之间学术联系较弱,还处于比较分散的状态。研究热点主要集中在政策制定、合法性有效性评估、群众认可及产业应用方面,新的研究前沿将是开拓民主渠道、完善监督机制、推动政府决策科学化等方面。

Systems composed of two types of nonidentical and dependent components

A coherent system of order n that consists two different types of dependent components is considered. The lifetimes of the components in each group are assumed to follow an exchangeable joint distribution, and the two random vectors, which represent the lifetimes of the components in each group are also assumed to be dependent. Under this particular form of dependence, all components are assumed to be dependent but they are categorized with respect to their reliability functions. Mixture representation is obtained for the survival function of the system's lifetime. Mixture representations are also obtained for the series and parallel systems consisting of disjoint modules such that all components of Type I are involved in one module (subsystem) and all components of Type II are placed in the other module. The theoretical results are illustrated with examples. © 2015 Wiley Periodicals, Inc. Naval Research Logistics 62: 388–394, 2015

Sharp bounds for the reliability of systems and mixtures with ordered components

In this article, we study how to derive bounds for the reliability and the expected lifetime of a coherent system with heterogeneous ordered components. These bounds can be used to compare the performance of the systems obtained by permuting the components at a given system structure, that is, to study where we should place the different components at a system structure to get the most reliable system. Moreover, a similar procedure is applied to get bounds for mixtures and for the generalized proportional hazard rate model when the baseline populations are ordered. © 2017 Wiley Periodicals, Inc.

On matched active redundancy allocation for coherent systems with statistically dependent component lifetimes

This study addresses the allocation of matched active redundancy components to coherent systems with base components having statistically dependent lifetimes. We consider base component lifetimes and redundancy component lifetimes which are both stochastic arrangement monotone with respect to a pair of components given the lifetimes of the other components. In this context, allocating a more reliable redundancy component to the weaker base component is shown to incur a stochastically larger system lifetime. Numerical examples are presented as an illustration of the theoretical results.
