试论我国当代消防文化建设的三个切入点

针对消防文化的内涵,探讨我国当代消防文化建设的三个切入点：即在消防工作中体现军人核心价值观、消防工作中的战斗精神与革命英雄主义气概、消防工作中的探索精神和创新意识;指出围绕这三个切入点进行消防文化建设的具体原则和措施.     

西部地区经济发展与社会稳定期刊文献研究

选择1991—2010年涉及西部经济发展水平多样性及影响西部地区社会稳定相关课题的期刊文献146篇进行分析研究。这些文献突出反映了我国西部地区存在的经济发展多样性特色,凸显出收入差距、东西部发展水平差异及其形成原因,西部的群体性事件与经济发展水平,西部地区发展水平多样的历史进程,经济发展与反恐怖,化解社会矛盾与少数民族权利及自我发展能力等9个方面的问题。同时指出了文献方面存在的不足,有待尽快得到有效解决。     

末端防御作战中火控雷达组网系统应用研究

火控雷达组网是应对未来末端防御作战挑战的有效途径。提出了基于指挥信息系统的火控雷达组网方式,并分析了该方式的优势。继而基于末端防御战斗部署一般要求和火控雷达组网系统对空侦察配系的特殊要求,经仿真计算得出和分析了火控雷达组网系统的典型对空侦察配系。最后详细论述了火控雷达组网系统的指挥控制要点。研究结果对于促进末端防御部队形成以信息系统为核心的体系作战能力具有重要意义。     

民族地区教师专业化发展困境解析

教师队伍建设与发展是民族地区教育发展的关键,而造成当前民族地区教师专业化发展困境的主要原因在于发展认识模糊、动力不足、能力薄弱、方式不当和制度不完善等因素。探索与构建民族地区教师专业化发展模式和发展途径,教育行动研究最为可贵、制度保障最为关键、教研成果转化为教育力最为紧要。     

基于 EEMD 的滚动轴承故障诊断方法

针对经验模态分解（empirical mode decomposition,EMD）方法处理轴承振动信号时存在的缺点,指出极值点的选择是产生模态混叠现象的原因。分析了集成经验模态分解（ensemble empirical mode decomposi-tion,EEMD）方法抑制模态混叠现象的原理,讨论了加入高斯白噪声的次数和大小对 EEMD 方法分解结果的影响,并通过仿真和实测信号对 EMD 和 EEMD 方法的性能进行了比较测试。结果表明：EEMD 方法不仅能够有效地抑制模态混叠现象,而且能更好地反映出轴承振动信号中的故障信息。同时,对通过 EEMD 方法得到的重构信号进行平方包络分析,结果证明：该方法能够有效地提取出滚动轴承的故障特征。     

Preserving defense technologies: A strategy for economic conversion†

This paper presents a model for converting legacy defense production facilities into private‐sector economic resources. Specifically, this paper will examine as a case study the first successful conversion of a former U.S. Department of Energy nuclear weapons production installation, including reasons for its success, its costs and benefits, and lessons for public policy. It is envisioned that this model may be useful for mitigating local economic hardship resulting from defense “downsizing” and for privatizing production capacities critical for national defense.     

How should modeling and simulation be used to support defense acquisition?

This paper investigates the potential for modeling and simulation to contribute to new defense system development, by increasing the productivity of traditional R&D in developing system‐specific technology. Building on a previous optimal control model of defense system R&D, it shows that (1) the optimal use of modeling is related in a natural way to that of traditional R&D, and (2) both have similar optimal profiles over time. Simulated results based on limited historical data suggest that optimal use of modeling could increase the rate of growth in system‐specific technology significantly.     

What Goes Up Must Come Down: Military Expenditure and Civil Wars

Abstract

This paper examines the impact of civil war on military expenditure. We employ two measures of military expenditure: the share of military expenditure in general government expenditure and the logarithm of military expenditures. We would reasonably expect a priori that military expenditure as a share of general government expenditure increases during a civil war and that such increases would taper off over the duration of a civil war. We also explore whether the termination of a civil war induces a decline in the share of military expenditure as a share of the general government expenditure in the short-run. We find evidence the of share of military expenditure increases during a civil war and falls in the year succeeding the end of a civil war, and, in particular, if a war ends in a peace treaty. The level of military expenditures, however, rises during civil wars and does not appear to decline in the short-term after the end of a civil war.     

Demobilisation,disarmament and reintegration in the Democratic Republic of Congo: The numbers game

Abstract

The creation of the Africa Command (AFRICOM) has reflected the growth in the strategic importance of Africa in US foreign policy since the end of the 1990s. One of the objectives of this new geographical military command is to forge closer links between foreign, security and development policies. However, this approach met with a number of difficulties associated with the challenge of ‘inter-agency cooperation’ among rather disparate actors from foreign affairs, defence and development. In addition, the establishment of AFRICOM has met with fierce criticism in the US and elsewhere – especially in Africa – culminating in the charge that the US foreign and development policies in Africa are being militarised. Although AFRICOM has a number of interesting features, this paper shows that it has reacted to these criticisms by realigning itself more closely with the traditional model of a military command, at the expense of the innovative interagency elements.
