军内行政执法主体研究

军内行政执法主体是指依法享有军内行政执法权的组织。但是,在理论上如何界定军内行政执法主体的范围？军内行政执法主体之间的相互关系如何界定？军内行政执法主体之间的职权在宏观上如何划分？这便是本文所要探讨的问题。     

海警部队参与海上反恐作战的思考

随着各国加强对空中和陆地恐怖主义的防控,恐怖主义把视角转向海上。海上恐怖主义具有事件的突发性、手段的多样性、处置的复杂性等特点。边防海警部队参与海上反恐作战有利于取得海上反恐斗争的胜利,有利于掌握海上反恐主动权,有利于顺应国际海上反恐斗争的形势。针对海上恐怖主义的特点,边防海警部队应做到以下几点：一是平时反恐作战准备应具有超前性,二是参与海上反恐作战应体现实效性,三是参与海上反恐作战应把握全局性。     

语文课程文本缺席现状及回归策略

在富有灵性的语文新课程中,阅读不能远离文本,远离作者,只有忠实于文本这一阅读中的特殊主体,以文本和作者的具体状况为基础的创造性阅读和个性化体验,才是语文新课程下真正的阅读。本文聚焦新课程小学语文阅读教学实践领域,分析随意肢解、拓展、歪曲、冲淡语文教材载体的文本缺席现状,从对文本价值的理解、文本处理规律的把握、教师引导阅读的作用和教师课程功力的提升四个角度,提出回归策略。     

禅宗思想对诗教审美文化的突破与超越

我国古代禅宗思想巧妙地实现了中国本土的儒道思想和西土印度的佛教思想的完美结合,同时也对我国古代语文教育产生了极大的影响。禅宗是真正中国化的佛教,它在审美主体意识、审美心理历程、审美修养途径、审美境界等方面突破与超越了我国古代的诗教审美文化,为我国当前的语文教育提供了有益的思考和启示。     

拟声修辞对英语语言音、意、形的辅助作用

拟声作为一种修辞格,主要有基本拟声和次要拟声两种形式,它常用于文学创作中,创造出所需要的音响效果,使人有身临其境之感,在语言的音韵,意像,形式上发挥着重要的修辞作用。     

基于RBF神经网络的HPA自适应预失真算法

卫星通信中,高速数据传输系统要求使用频谱利用率高的高阶调制技术,但高阶调制对高功率放大器(HPA)的非线性非常敏感,会造成码间干扰和邻信道间干扰.提出一种基于RBF神经网络的自适应预失真算法,以实现HPA的线性化,同时推导了自适应算法的迭代公式.仿真结果表明,该算法能明显改善信号星座图,并能大大提高系统的误比特率性能.     

推进党的建设伟大工程的一项重要举措

反腐倡廉建设与思想建设、组织建设、作风建设、制度建设并列为党的五大建设,是党的十七大以改革创新精神推进党的建设伟大工程的重要举措。加强军队党的反腐倡廉建设,必须以胡主席关于"三个更加"的重要思想为指导,建立健全反腐倡廉建设的长效机制,保证军队党的反腐倡廉建设健康、深入、持续发展。     

Sojourn times in G/M/1 fork‐join networks

We consider a processing network in which jobs arrive at a fork‐node according to a renewal process. Each job requires the completion of m tasks, which are instantaneously assigned by the fork‐node to m task‐processing nodes that operate like G/M/1 queueing stations. The job is completed when all of its m tasks are finished. The sojourn time (or response time) of a job in this G/M/1 fork‐join network is the total time it takes to complete the m tasks. Our main result is a closed‐form approximation of the sojourn‐time distribution of a job that arrives in equilibrium. This is obtained by the use of bounds, properties of D/M/1 and M/M/1 fork‐join networks, and exploratory simulations. Statistical tests show that our approximation distributions are good fits for the sojourn‐time distributions obtained from simulations. © 2008 Wiley Periodicals, Inc.

Ambulance location for maximum survival

This article proposes new location models for emergency medical service stations. The models are generated by incorporating a survival function into existing covering models. A survival function is a monotonically decreasing function of the response time of an emergency medical service (EMS) vehicle to a patient that returns the probability of survival for the patient. The survival function allows for the calculation of tangible outcome measures—the expected number of survivors in case of cardiac arrests. The survival‐maximizing location models are better suited for EMS location than the covering models which do not adequately differentiate between consequences of different response times. We demonstrate empirically the superiority of the survival‐maximizing models using data from the Edmonton EMS system. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2008     

What you should know about simulation and derivatives

Derivatives (or gradients) are important for both sensitivity analysis and optimization, and in simulation models, these can often be estimated efficiently using various methods other than brute‐force finite differences. This article briefly summarizes the main approaches and discusses areas in which the approaches can most fruitfully be applied: queueing, inventory, and finance. In finance, the focus is on derivatives of another sort. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008
