试论应急管理体系的财政支撑

从2003年的“非典”开始,我国逐步建立起了一套应急管理体系,在南方冰雪灾害、汶川地震以及今年的玉树地震和南方水灾等抗震救灾工作中发挥作用并不断完善。财政支撑在应急管理体系中有着至关重要的作用。对目前我国应急财政管理现状进行分析,结合对外国应急管理体系先进做法的借鉴,提出了对建立健全应急财政支撑体系的政策建议。     

军事攻防中的多属性资源分配对策模型

针对资源受限情形下的两阶段攻防资源分配问题,提出一种基于多属性决策的资源分配对策模型。防守者首先将有限的防护资源分配到不同的目标上,继而进攻者选择一种威胁组合方式对目标实施打击。基于博弈论相关知识,模型的求解结果可以使防守者最小化自身损失,使进攻者最大化进攻收益。同时,针对模型的特点,给出了一些推论和证明。通过一个示例验证了模型的合理性以及相关推论的准确性,能够为攻、防双方规划决策提供辅助支持。     

Building peace from the margins in Somalia: The case for political settlement with Al-Shabaab

The prevailing discourse in Mogadishu among the federal government of Somalia and the international community is that Al-Shabaab is no longer relevant in contemporary Somali political landscape. In the language of the government, Al-Shabaab is like a lost crocodile thrown out from the river. In the lexicon of the international community, Al-Shabaab is gradually receding. In fact, Al-Shabaab is actually puissant and potent in terms of social, political and military capabilities; not just in Somalia, but also in the wider East Africa region. Why is Al-Shabaab resilient and resistant? Why is it even more effective than the federal government? To answer these questions, this article reveals how Al-Shabaab is increasingly more legitimate than the federal government. In conclusion, the article proposes that negotiated settlement with the insurgency movement could lead to peace in war-torn southern Somalia.

从哲学史上自然观的变革看医学模式的转变

从哲学史上自然观的变革对医学模式转变的影响看,自然观对科学发展起指导作用.科学技术领域中形成和发展的一系列新技术和有关理论如系统论、控制论、信息论这些理论本身已经具备了某些哲学的特性,在医学模式的变革中发挥了积极的意义,表现出科学、哲学、方法论相互渗透的趋势.     

论李煜词的文化内蕴

李煜的词是中国词坛上的一朵奇葩,不仅清丽自然,真情流露,而且是亡国之君情感的真实写照。其前期词轻描淡写却能再现栩栩如生的生活画面,后期词情深哀切,以有形的物来形容无形的愁,遣词用字准确贴切,艺术概括高度凝炼。     

一种面向任务的通用仿真资源集成管理平台的设计与实现

应用锤击法的大型复合材料桁架结构段自由振动分析

复合材料桁架结构以其轻质和优异的力学性能应用于大型航天航空飞行器结构,其承载能力和振动特性是决定其应用效果的关键因素。本文考察了大型碳纤维/环氧复合材料方形截面桁架结构段的自由振动特性。采用锤击法实验测试得到了复合材料桁架结构段自由振动的模态和频率,并与有限元数值模拟结果进行对比分析,论证了锤击法测试振动特性在复合材料桁架结构上应用的可行性和准确性。     

军队政治工作信息资源元数据标准

随着政治工作信息资源管理的需要,运用元数据来描述政治工作信息资源正逐渐成为普遍趋势,由于政治工作信息资源来源广泛种类复杂,如果缺乏顶层设计,势必会造成元数据标准不统一不规范的现象,从而影响政治工作信息资源管理。文章研究军队政治工作信息资源元数据标准的内涵,阐述其在政治工作信息化建设中的作用价值,提出具体设计应该遵循的原则和步骤。     

A model of supply-chain decisions for resource sharing with an application to ventilator allocation to combat COVID-19

We present a stochastic optimization model for allocating and sharing a critical resource in the case of a pandemic. The demand for different entities peaks at different times, and an initial inventory for a central agency are to be allocated. The entities (states) may share the critical resource with a different state under a risk-averse condition. The model is applied to study the allocation of ventilator inventory in the COVID-19 pandemic by FEMA to different U.S. states. Findings suggest that if less than 60% of the ventilator inventory is available for non-COVID-19 patients, FEMA's stockpile of 20 000 ventilators (as of March 23, 2020) would be nearly adequate to meet the projected needs in slightly above average demand scenarios. However, when more than 75% of the available ventilator inventory must be reserved for non-COVID-19 patients, various degrees of shortfall are expected. In a severe case, where the demand is concentrated in the top-most quartile of the forecast confidence interval and states are not willing to share their stockpile of ventilators, the total shortfall over the planning horizon (until May 31, 2020) is about 232 000 ventilator days, with a peak shortfall of 17 200 ventilators on April 19, 2020. Results are also reported for a worst-case where the demand is at the upper limit of the 95% confidence interval. An important finding of this study is that a central agency (FEMA) can act as a coordinator for sharing critical resources that are in short supply over time to add efficiency in the system. Moreover, through properly managing risk-aversion of different entities (states) additional efficiency can be gained. An additional implication is that ramping up production early in the planning cycle allows to reduce shortfall significantly. An optimal timing of this production ramp-up consideration can be based on a cost-benefit analysis.
