装备保障能力生成与黏性研究

作为军队战斗力的重要组成部分,动态环境下装备保障能力生成研究成为关注的焦点。针对新军事变革条件下装备保障能力生成问题,采用黏性思想,分析了新军事变革对装备保障能力生成的需求,从要素维、结构维和运行维3方面对装备保障能力生成系统黏性现状进行了剖析,并从哲学的角度对黏性成因进行了研究,最后针对黏性对未来一体化联合作战条件下装备保障能力生成的发展对策进行了探讨,为系统认识和指导装备保障能力生成实践提供思路和新视角。     

A note on optimal pricing for finite capacity queueing systems with multiple customer classes

This article investigates optimal static prices for a finite capacity queueing system serving customers from different classes. We first show that the original multi‐class formulation in which the price for each class is a decision variable can be reformulated as a single dimensional problem with the total load as the decision variable. Using this alternative formulation, we prove an upper bound for the optimal arrival rates for a fairly large class of queueing systems and provide sufficient conditions that ensure the existence of a unique optimal arrival rate vector. We show that these conditions hold for M/M/1/m and M/G/s/s systems and prove structural results on the relationships between the optimal arrival rates and system capacity. © 2008 Wiley Periodicals, Inc.

在越轨行为之外:大学生隐性逃课的社会学分析

隐性逃课是指学生上课时消极参与课堂教学的精神旷课行为,多被认为是越轨行为的一种表现。从社会学视角切入,对大学生隐性逃课问题进行分析,发现将隐性逃课视作越轨行为实际上是学术研究和教学实践过程中简单定性的结果,是对隐性逃课性质的片面反映。这种越轨定性导致了对隐性逃课功能认识、原因分析和应对路径设计的偏离。大学生隐性逃课具有社会根源,是多元社会与高校统一管理之间的张力以及大学无用论和信任危机的产物。在越轨属性之外,大学生隐性逃课还是一种去学校化的反抗和师生之间的默契妥协。因此,对于大学生隐性逃课,应将其置放在社会背景中加以思考,引发人们对社会根源和社会规则本身的关注。     

对一个重要极限证明中使用循环论证问题的质疑

有的著作认为在极限公式limx→0sinxx=1的证明中,要用到圆(扇形)的面积公式S=21Lr,而对后者的证明中必须要用到重要极限limx→0sinxx=1,从而犯了循环论证的错误。魏晋刘徽的“割圆术”是对无限问题的独特认识和致用的处理方式,是为证明圆面积公式而设计出来的一种方法。刘徽之前,希腊的阿基米德用穷竭法也证明了圆的面积公式。其中,刘徽的证法强调计算的程序性和构造性,而阿基米德则倾向于演绎的严谨性。这两种证明说明limx→0sinxx=1证明所谓的循环论证是可以避免的。

Threats and civil–military relations: explaining Singapore’s “trickle down” military innovation

This article explains why Singapore, despite its small size and semi-authoritarian regime, retains one of the best military forces in the Indo-Pacific. It unpacks Singapore’s ability to continuously innovate since the 1960s – technologically, organizationally, and conceptually – and even recently joined the Revolution in Military Affairs bandwagon. Drawing from the broader military innovation studies literature, this article argues evolutionary peacetime military innovation is more likely to occur in a state with a unified civil–military relation and whose military faces a high-level diverse set of threats. This argument explains how the civil–military fusion under the People’s Action Party-led government since Singapore’s founding moment has been providing coherent and consistent strategic guidance, political support, and financial capital, allowing the Singapore Armed Forces to continuously innovate in response to high levels and diversity of threats.     

The Millenials’ war: dilemmas of network dependency in today’s military

This work is about how the United States military has become dependent on networked technology. As arguably the largest contributor to national security, it has become so dependent that its chief doctrine integrates networked technology into nearly every specialty, with particularly intense focus on Network Centric Warfare. As the military’s old guard is replaced by the highly technical Millenial Generation, there is cause to pause when assuming this techno-acuity brings nothing but advantage and success. Vulnerabilities stemming from such extensive dependence offer opportunities for exploitation that have not gone unnoticed. The first step to moving forward from this point is to fully understand the extent to which the military has become dependent on computer networks. It might be the Millenials’ war today, but it would be quite unwise for the United States military to think about it and fight it in a purely Millenial way.
