棕垫材料火灾危险性的热解动力学研究

利用热重分析仪,通过空气与氮气下棕垫材料的对比试验,建立热解表观动力学模型,对棕垫材料的火灾危险性进行分析。通过对试验数据的分析表明,在空气气氛下,棕垫材料第一步失重阶段热解表观动力学模型较好地符合相界反应球形对称模型,第二步与第三步失重阶段较好地符合二级反应模型,活化能范围为32.42-59.09 kJ·mol^-1;在氮气气氛下,棕垫第一步失重阶段较好地符合二级反应模型,第二步失重阶段较好地符合零级反应模型,活化能范围为56.92-72.56 kJ·mol^-1。对比分析其他室内材料的燃烧属性表明,棕垫材料活化能较低、热稳定性差。说明棕垫材料是一种易燃烧物质,火灾危险性较大。

网民心理视角下的网络舆情引导机制研究

在网络舆情频发的社会背景下,加强网民心理的分析和研究是完善网络舆情引导的重要举措。通过列举几种网民心理的类型,分析在这些心理的作用下网民在网络舆情中的行为表现。从网民心理疏导的角度出发,从引导主体、引导机制和引导渠道三个方面考虑,解决基于网民心理的网络舆情引导问题,为政府应对网络舆情事件提供理论支撑。     

易燃可燃介质的压力容器火灾事故处置对策探讨

压力容器内的工作介质大多为易燃、易爆和有毒物质,一旦发生泄漏或火灾事故,就会造成重大经济损失和人员伤亡。根据压力容器的形状、结构特点、火灾特点和多年参加压力容器火灾事故处置取得的经验,提出处置压力容器火灾事故的基本对策。     

基于SNA参数的网络舆论系统状态差分分析

近年来,互联网在我国快速发展,网络舆论起着越来越重要的作用,对国家安全和社会稳定产生了重大的冲击和影响。针对网络舆论系统的状态进行研究,借助SNA方法,提出了可作为序参量的一些特征参数。在此基础上,设计了基于时间序列的SNA参数差分算法,实现对网络舆论系统的状态进行观测与分析。同时,对一个真实网络舆论进行实验仿真,验证了这种方法。     

Terrorism in Nigeria

Using the Boko Haram terrorist group in Nigeria as a point of departure, this paper examines the implications of the operations of terrorist groups on the security and stability of states in West Africa. It predominantly utilises secondary sources of data. Findings indicate that the membership and operations of this terrorist group are spreading across the sub-region. This spread is consequent upon Boko Haram's collaboration with other terrorist groups within West Africa and beyond. This constitutes threats to the security and stability of states in the sub-region. Thus, the paper recommends, among other things: a thorough understanding of the operational strategies of terrorist groups by states and those involved in security policymaking in the sub-region; and for agreements to be reached among Economic Community of West African States (ECOWAS) member states and their governments for collaboration in various areas in order to curtail transnational crime and terrorism, and reduce socio-economic inequality that generates aggressive behaviours among the less privileged.     

2015 and the survival of the Nigerian State

Nigeria is currently faced with serious domestic challenges. While the state is not officially at war, it is standing on the precipice, especially with the eruption of violence occasioned by the emergence of the Boko Haram sect and the tenuous peace in the Niger Delta. With the 2015 general elections on the horizon, fears of further violence and disintegration are rife, more so because of the debate over who occupies the Presidential Villa at Abuja. President Goodluck Jonathan, a southerner, seems poised for a comeback even amidst the vociferous challenge posed by the political elites of northern Nigeria. This article looks at the different scenarios that might play out in 2015. It analyses the challenges of the survival of the Nigerian state, and makes some policy recommendations that Nigeria and its people need to put into place in order to ensure its survival beyond 2015.
