营区文化景观塑造之思考

文化景观在现代营房建设及部队发展过程中发挥着举足轻重的作用,为打造营区特色文化,分析了营区文化景观的内涵和意义,指出了当前营区文化景观建设中存在的主要问题,并在此基础上提出了营区文化景观塑造的策略:尊重地域特色;挖掘营区历史;凸显主题精神;打造创意小品。     

谈营区综合治理经费保障的标准化

一、从历史的经验教训,看实行营区综合治理经费保障标准化的必要性. 对部队营区实行综合治理,经历了一个从不认识到认识,从不完善到逐步完善的过程。 1977年,总参谋部、总后勤部颁发1978至1985年全军营区建设规划纲要,把“因地制宜、全面规划、依靠群众、勤俭办事、面向基层、保障战备”作为部队营区建设的指导方针,明确提出了部队营区建设中营房、设备、营具、附属工     

坚持标准 狠抓营房规范化管理

近年来,我总队按照“保障有力”的要求,以《纲要》和《营区房地产正规化管理标准》为依据,坚持连续打基础,接力抓建设,在营房规范化管理上狠下功夫。通过几年的努力,全省部队基本实现“营房住用标准化、营具配置统一化、营区布局合理化、环境优美园林化”的目标,官兵住房及生活设施得到极大改善,增强了部队的凝聚力和战斗力,有力地促进了部队的全面建设。     

社会改革对营房勤务的影响

近几年来,社会变革使营房勤务面临的许多新情况、新问题,其范围之广泛,影响之深刻,确实是过去几十年来在我军不曾有过的: 城镇建设的迅速发展,使部队营区“不可侵犯”的独立性受到程度不一的冲击;社会主义商品经济的发展,向营房工作的传统办法和经验提出了全面挑战;房地产经营和建筑业的崛起,给营房勤务带来了许多新问题;转业、退休军官滞留部队营房,使军队家属住房面临困境。     

旧房整治之我见

在营以下部队营区综合治理工作中,对老旧房的整治问题,逐渐引起了各级营房部门的重视,并有许多文章相继进行观点不同的探讨。如何立足部队现实,有效地搞好营以下部队营区综合治理中旧房整治,对此问题我们愿与大家共同探讨。一是从国民经济发展,看旧房整治的适应性。赵紫阳同志在党的十三大报告中明确     

严格制度 规范管理 努力提高营房综合保障能力

近年来，我部严格按照《中国人民解放军房地产管理条例》和武警总部有关房地产管理的制度规定的要求，把营房规范化管理作为加强部队全面建设的一件大事来抓，使部队营房始终处于良好的住用状态，供水、供电设备运转正常，营房设施、营具齐全配套，综合保障能力增强，营区环境绿化也达到园林式营院要求。先后被榆次市政府、山西省政府评为花园式单位和绿化先进单位。     

高起点 高标准 提高营房规范化管理水平

近年来,我总队坚持以《纲要》和《营区房地产正规化管理标准》为依据,以总队全面加强基层部队建设为契机,立足高起点,坚持高标准,狠抓营房规范化管理,提高了营房的综合保障效益。我们的主要做法是：     

编制营区规划应注意的几个问题

营区规划是营区建设的发展方向和目标，也是管区建设、改造、管理的依据。而营区规划的编制更是一项复杂的工作，是营房建设与管理的一件大事，是节约营区建设投资关键环节。为了扎扎实实地做好这项工作，笔者深入部队进行了多次调查研究，在分析和总结调研成果的基础上，提出了编制营房规划应注意的三个方面的问题，即：应树立“四个意识”，处理好“三个关系”与克服“两种思想”，并分别作了较为详细的阐述。     

高标准落实营产规范化管理

近几年来，我们按照总部下达的驻监狱部队营房整治和“解困工程”任务，先后对近百个支队机关、教导队、大队部、基层中队的营区、营房和附属设施进行了综合整治，统一配备了制式床、学习桌椅、储物柜等营具设施，对营区及设施进行了统一规划和科学安排，驻监狱部队营房设施建设发生了翻天覆地的变化，使绝大多数基层中队官兵住上了宽敞明亮的楼房，促进了部队全面建设，增强了部队凝聚力和战斗力。随着各项建设任务的完成，管理工作已摆在部队营房建设的重要位置。“一流的营房、一流的设施，必须有一流的管理水平”。为了做到这一点，我们在落实营产管理工作中注重从以下三个方面下功夫。     

节约营区规划造价的有效途径

屯兵设营,规划先行。营区规划是部队发展所面临的重要问题,随着“节约型社会”建设步伐的加快,部队营区规划的节约化也成为一个热门话题。从实证分析的角度,结合笔者多年的相关实践经验,指出了如今营区规划工作中存在的误区,对如何节约营区规划造价进行了探讨,并提出相应途径。从为部队推广可行性强的政策策略为出发点进行论述,容易为广大部队营房干部掌握,对部队营区规划工作具有一定的指导意义。

基于构建武警部队应急军械移动库房的考虑

武警部队支队（团）级在遂行多样化任务过程中,军械装备的途中运输、驻地储存和野外管理都存在着不同程度的安全隐患。为解决这一问题,通过调研、听取部队反映和充分论证,提出亟待研制武警部队支队（团）级应急军械移动库房的设想,并借鉴厢式汽车和军用方舱的结构和技术,进而确立设计理念,分析设计思路,研究攻关重点,设置安全模块,形成全新的移动库房,以保障部队应急需要。     

Security,structural factors and sovereignty: Analysing reactions to Kenya’s decision to close the Dadaab refugee camp complex

Kenya’s decision to close the Dadaab refugee camp complex highlights structural flaws in the international refugee regime. While much attention has been paid to Kenya’s reasoning, less has been given to the reactions of organisations and states. Given the state’s primacy in the international system and uncertainty about refugees, Kenya’s decision is perhaps unsurprising. It is contended that the stakeholders were unprepared because of path dependence and disbelief that Kenya would repatriate the refugees. While stakeholder reactions arguably demonstrate concern for refugees, the international refugee regime remains unquestioned, sustaining revenue streams that may fuel corruption, encourage lengthy encampment and prolong conflict.     

Risk‐sensitive sizing of responsive facilities

We develop a risk‐sensitive strategic facility sizing model that makes use of readily obtainable data and addresses both capacity and responsiveness considerations. We focus on facilities whose original size cannot be adjusted over time and limits the total production equipment they can hold, which is added sequentially during a finite planning horizon. The model is parsimonious by design for compatibility with the nature of available data during early planning stages. We model demand via a univariate random variable with arbitrary forecast profiles for equipment expansion, and assume the supporting equipment additions are continuous and decided ex‐post. Under constant absolute risk aversion, operating profits are the closed‐form solution to a nontrivial linear program, thus characterizing the sizing decision via a single first‐order condition. This solution has several desired features, including the optimal facility size being eventually decreasing in forecast uncertainty and decreasing in risk aversion, as well as being generally robust to demand forecast uncertainty and cost errors. We provide structural results and show that ignoring risk considerations can lead to poor facility sizing decisions that deteriorate with increased forecast uncertainty. Existing models ignore risk considerations and assume the facility size can be adjusted over time, effectively shortening the planning horizon. Our main contribution is in addressing the problem that arises when that assumption is relaxed and, as a result, risk sensitivity and the challenges introduced by longer planning horizons and higher uncertainty must be considered. Finally, we derive accurate spreadsheet‐implementable approximations to the optimal solution, which make this model a practical capacity planning tool.© 2008 Wiley Periodicals, Inc.

基于Hash运算的IPv6地址的分配与验证

目前在网络中，基于仿冒IP的攻击非常普遍，在IPv4中源地址验证比较困难，而在IPv6中，地址位较长，使得基于地址本身验证IP是否合法成为可能。Hash运算具有计算的单向性、寻找相同散列值的明文消息的困难性和对初值的敏感性，利用Hash运算生成IPv6地址，增加了伪造的难度，有效地防止了基于仿冒IP的攻击。     

Aircraft routing under the risk of detection

The deterministic problem for finding an aircraft's optimal risk trajectory in a threat environment has been formulated. The threat is associated with the risk of aircraft detection by radars or similar sensors. The model considers an aircraft's trajectory in three‐dimensional (3‐D) space and represents the aircraft by a symmetrical ellipsoid with the axis of symmetry directing the trajectory. Analytical and discrete optimization approaches for routing an aircraft with variable radar cross‐section (RCS) subject to a constraint on the trajectory length have been developed. Through techniques of Calculus of Variations, the analytical approach reduces the original risk optimization problem to a vectorial nonlinear differential equation. In the case of a single detecting installation, a solution to this equation is expressed by a quadrature. A network optimization approach reduces the original problem to the Constrained Shortest Path Problem (CSPP) for a 3‐D network. The CSPP has been solved for various ellipsoid shapes and different length constraints in cases with several radars. The impact of ellipsoid shape on the geometry of an optimal trajectory as well as the impact of variable RCS on the performance of a network optimization algorithm have been analyzed and illustrated by several numerical examples. © 2006 Wiley Periodicals, Inc.
