Intellectual spring cleaning: it’s time for a military “Do Not Read” list; and some sources that should be on that list

Military reading lists, intended to promote professional reading and in turn enhance education and develop critical thinking skills and sound judgement, recommend key texts to military personnel. This is a noble intent but the lists themselves, while generally good, are not flawless. Critiques of military reading lists often focus on what sources they are missing. This article offers its own critique but from a different perspective. It does so by analysing why some sources, which have become outdated, are based on faulty or incomplete research, have been thoroughly disproven, or some combination of the above, nevertheless linger on military reading lists. It then offers a short list of such sources, which it recommends be either removed from existing reading lists or accompanied by other sources that place the original source in appropriate historical context. Where applicable, it also recommends alternative sources that provide insights into the same subject matter. In so doing, this article is intended generate debate and to assist militaries to achieve a better balance between evaluation, induction and retention of valid knowledge on one hand, and rejection of outdated or flawed knowledge on the other.

Health Insurance,Health Conditions,and Veteran Health Care Utilization

Abstract

The utilization of health care services by veterans has received much attention in recent years. However, the impact of the large array of factors affecting the veterans’ demand for health care services remains understudied. These factors include individual socio-demographic and economic characteristics, the availability of various sources of health insurance, and the prevalence of medical conditions. We use public data to analyze how veterans’ utilization of health care services varies with these factors. We also analyze how the reliance on VA services varies when alternative sources of health insurance are available to veterans. Based on the estimated relationships, we use a micro-simulation model to forecast future health care utilization, both inside and outside of VA.     

非致命防暴动能弹作战效能评估

提出了非致命防暴动能弹作战效能的评估法,分析了非致命防暴动能弹的技术性能,建立了以非致命性为核心指标的防暴动能弹效能指标体系。采用定性分析与定量分析相结合,将集对分析法应用到了非致命防暴动能弹的效能评估中,对3种防暴动能弹进行了效能评估。为非致命防暴动能弹的研发生产提供了重要的理论支撑。     

结合兰彻斯特方程分析战场地形因素对战争的影响

针对现代战争中地形对作战制约因素增多的问题,在兰彻斯特作战模型基础上,加入战场地形因素,分析对战争的影响。本文介绍了兰彻斯特方程的改进与发展,通过地形对通行和隐蔽的影响分类,构建一种反映地形因素的作战模型,并运用Matlab软件编写模型算法进行仿真计算。仿真结果表明:该模型可在一定程度上反映地形因素对战争的影响,同时说明了合理有效发挥地形优势可以达到以少胜多、以弱胜强的军事目的。     

公众聚集场所火灾危险性评估方法研究

针对公众聚集场所火灾危险性特点,从建筑特征、危险源、消防设施、人员疏散和安全管理等五个方面建立火灾危险性评价指标体系。在此基础上通过专家打分和层次分析法,计算得出各指标因子的权重值,根据有关标准和规范,对各评价指标因子进行等级划分,设计安全检查评分表,采用线性加权模型,计算该场所的系统安全分值,得出火灾危险性评价结果。最后给出一个评估实例,对评估方法进行验证。
