城镇化建设对基础教育发展的相关影响研究综述

为顺应城镇化建设的需要,政府通过学校布局调整将农村乡镇学校大幅度合并,对城乡中小学校点布局进行了全面调整,期间大量义务教育阶段的学生也随父母由农村迁移到城市,城乡人口的年龄结构和空间分布发生了变化,也对教育资源的配置和使用带来了一定的影响。随着城镇化进程的不断加快,基础教育资源布局的优化等问题的解决直接影响新一轮城镇化的向前推进。因此,本文将在国内已有研究基础之上,通过文献法归纳总结城镇化建设对基础教育发展带来的积极影响和挑战,以期更好地把握两者的关系,促进其协调发展。     

An enterprise portfolio approach for defence capability planning

Capability-based planning (CBP) is considered by many defence organisations to be the best practice for enterprise-level planning, analysis and management. This approach, loosely based around investment portfolio theory, is premised on balancing the cost, benefit and risk of capability options across the defence enterprise. However a number of authors have recently noted limitations of its current applications. The authors propose a more general, insurance-based approach, which can support the evolutionary improvement of the current CBP approach. This approach is implemented as hedging-based planning and aims to better reflect the enterprise nature of defence organisations, capturing both force structure and force generation aspects of military systems.

翼伞精确空投系统归航轨迹规划与控制?

翼伞归航轨迹规划与控制问题是翼伞系统在一定初始状态下,利用自身可操作性,完成从初始位置到目标位置的转移问题。针对翼伞空投系统不同归航要求,规划出满足精度要求为圆径概率误差（ CEP ）小于40m的归航轨迹并经过一定量的控制完成翼伞空投系统精确空投任务。首先建立翼伞系统状态空间六自由度模型,并在此基础上提出系统简化稳态模型,通过最优控制方法,规划出满足空投要求的最优归航轨迹后对翼伞进行不断控制直至目标点。最后通过Matlab仿真试验,绘出翼伞系统归航轨迹图与控制变化图。

Planning versus Chaos in Clausewitz's On War

Clausewitz laid great emphasis on the planned construction of war, but this idea has received little attention from his commentators, who generally attach far greater importance to what he said about the chaotic elements of war, in particular its interactive nature and the friction inseparable from its conduct. This article gives long-overdue recognition to planning as a dominant theme of On War. The essential point Clausewitz makes concerning interaction is not that the enemy's responses are bound to disrupt our plans, but that our plans must aim to predict and incorporate his responses. Clausewitz acknowledges that friction creates enormous difficulties for the realization of any plan, but it is precisely in respect of this challenge that he develops the concept of military genius, whose capabilities are seen above all as the executive arm of planning.
