环境新闻在中国的发展及其特征简析

环境问题已经成为一大社会问题,环境新闻成为媒体和公众关注的焦点。国内环境新闻作为一个新兴的报道题材,已迅速闯进主要新闻传媒的主阵地,并逐渐成为与时政新闻、经济新闻、科技新闻等并驾齐驱的报道领域,成为各家传媒和记者争相采访报道的重要内容。本文从环境新闻的概念与产生入手,分析其在中国的发展。     

基于迭代Bargaining策略优化服务合成执行路径

服务质量(QoS)是优化服务合成执行路径的关键研究内容,当前绝大多数存在的方法很少注意到商业环境下服务商之间存在的隐性竞争压力可能会迫使服务商动态改变他们的QoS值以至于合成优化执行路径发生改变.针对此问题,提出一个基于迭代Bargaining策略的约束违背纠正方法.该方法使用本地最优化策略,在没有考虑用户QoS约束的情况下建立一条最优执行路径.对此路径,全局QoS计算模型和全局约束违背检查模型能找出所有发生的约束违背.一个迭代的Bargaining策略被递归作用于关键路径执行节点,使得更好服务提供商被选出替换原有执行节点,从而一个优化的执行路径能被重新建立以满足用户综合的QoS约束需求.     

边防毗邻省区跨域协同警务战略研究

在非传统安全威胁不断增多的情况下,公安边防部队维护边疆社会治安和政治大局稳定的职能作用更加凸现。针对公安边防部队点多、线长、面广的特点和毗邻省区结合部管理防范相对薄弱的实际,研究探索新形势下加强毗邻跨域警务协同、联手固边的工作机制,形成无缝链接——“全国边防一盘棋”的整体战略,全面提升公安边防部队战斗力,具有极其重要的现实意义。     

中德警卫人员招募与教育训练比较

德国要人防护局招募警卫人员的理念是“把一名警察变为一名警卫”,而且要求应招者必须经过三到五年的警察培训,并且具备射击、法律、搏击等方面的基础。中国警卫人员招募途径多元,强调严把“入口关”。德国警卫部门在教育训练方面强调“完全贴近实战”。中国警卫部门则采取多种教育训练模式,强调“战训合一”。通过比较研究发现,德国警卫部门在人员招募与教育训练方面有很多先进的理念和做法值得中国警卫部门学习和借鉴。     

基于多信号模型的装甲车辆电源系统诊断策略

针对装甲车辆电源系统模块失效和信号失效不统一的特点,提出了一种多信号模型的改进方法,在此基础上,通过电源系统故障模式影响分析,建立了电源系统测试性模型。基于故障熵理论,利用诊断信息量和费用优化的启发式函数,确立了系统的诊断策略。计算结果表明:该方法对诊断策略的优化是有效的。该方法对装甲车辆电源系统诊断策略的研究具有一定参考意义。     

基于DSPACE的高功率密度柴油机智能化冷却系统控制策略验证

为了验证高功率密度柴油机智能化控制冷却系统控制策略是否正确,以DSPACE为基础搭建了半实物仿真试验平台;通过仿真试验平台验证,控制策略符合柴油机冷却系统工作要求,电控阀、传感器、驱动电路等部件工作可靠,节省了研制时间、经费,降低了研制风险。     

SINS/CNS组合导航的导航星表构建方法

构建满足完备性、精简性和查询快速性的导航星表是实现捷联惯性/星光组合导航系统的重要前提和保证。以天文学中的Tycho-2星表作为导航星表的初始星表,对球矩形分区方法进行了改进,包括明确分区及子分区的划分方法,提出了备选导航星的选择策略。实验结果表明,采用改进型球矩形分区方法的备选导航星数量最多只占赤纬带法导航星的19.37%,仅占全天遍历法导航星的3.12%。因此,改进型球矩形分区方法更加精准,查询更快捷,更适用于捷联惯性/星光组合导航系统。     

Beyond Just War: Military Strategy for the Common Good

The objective of this article is to move ethical discourse on military strategy beyond the confines of the established War Convention. This is achieved by utilising the common good, a concept found in political philosophy and theology. The common good acts as a positive organising concept for socio-political activity. With its focus on peace, development and the flourishing of the individual and community, the common good poses a significant challenge to strategy. This article constructs an approach to strategy that is compatible with the common good. Importantly, it does so whilst respecting the pursuit of victory as an indispensable component of strategy’s true nature. The theory presented in this article is then tested in relation to four different modes of strategy: regular war, irregular war, deterrence, and cyberwar.     

Ordering and controlling the dimensions of strategy

Colin Gray’s dimensions of strategy, built upon the earlier work of Clausewitz and Howard, has theoretical, practical, and pedagogic value for the Strategic Studies community. This paper further develops the theory, arguing that the dimensions can be controlled or managed to improve strategic performance. The dimensions are divided into two categories: “internal” and “external” to the process of strategy. The paper describes the dynamic process by which the internal dimensions, which can be controlled, are used to exert influence over the external dimensions that are beyond the control of the strategist. It is argued that six dimensions hold the key to strategic success: politics and the five dimensions concerned with warfighting. This conclusion validates the Clausewitzian paradigm with its emphasis on policy and battle.     

Brothers in arms,yet again? Twenty-first century Sino-Russian strategic collaboration in the realm of defence and security

2014–2015 were years of turmoil for strategic relations, with Sino-Russian relations emerging as a particularly interesting set of ties to observe. This article asks whether recurrent Sino-Russian exhortations of friendship are mirrored by their strategic alignment in the defence and security realm, half a century after the end of the Sino-Soviet pact during the communist era. We examine the arms trade between the two countries and with regional partners, but also the recent pattern of bilateral and multilateral military exercises, as a combined test of the security and defence relationship. We are able to show that the image of friendship that both Moscow and Beijing like to promote, while apparent at the UN Security Council and within the BRICS group, remains constrained by rivalry in high-tech segments of the arms industry and by lingering concerns about the prospects of peer interference in their shared regional vicinity.
