‘Responsibility to protect’ and the African Union: Assessing the AU’s capacity to respond to regional complex humanitarian and political emergencies

Despite its many institutional and political weaknesses and limitations, the African Union (AU) has been developing a variety of tools and mechanisms to respond effectively to complex disasters and emergencies (both natural and manmade) by building up a comprehensive regional security architecture. Furthermore, it has become the first and only regional or international organisation to enshrine the principle of ‘responsibility to protect’ (R2P) in its Constitutive Act. This regional approach to and formal endorsement of the R2P principle allowed it to assume a particular place in the promotion of peace and security in its area. This article aims to critically assess the effectiveness of the AU on the African continent by exploring its real capacity in preventing and responding to emergencies and violent conflicts, and therefore in rendering the principle of R2P operational. The article argues that the formalisation of principles does not necessarily mean their effective implementation. The organisation's use of the R2P principle is also greatly conditioned by internal and external factors.     

导弹结构热防护一体化设计与优化

针对导弹面临的严酷气动热力环境,基于传统波纹夹芯结构,为导弹设计了一种兼具承载和热防护功能的一体化结构。建立热-结构耦合计算模型,对一体化结构进行结构承载与热防护性能分析,结果表明:一体化结构在高温下具有较好的承载能力;增加一体化结构隔热层与内壁厚度有助于提高导弹的热防护效率。以一体化结构热防护效率最高和质量最小为目标,采用第二代非支配排序遗传算法实现了多目标优化,并认识到:一体化结构热防护效率与质量相互影响,设计时需要需综合考虑。     

军事安全视角下的军队翻译能力建设

军队翻译能力是军队外语能力的组成部分。军队翻译能力的理论框架包含构成要素、存在形式和转换机制三个组成部分。新的安全形势对我军的翻译保障在广度和深度上都有了新的要求,而军队翻译能力供给相对不足。需要对军队翻译能力进行规划,加强翻译人力资源的储备与管理,提升翻译保障信息化水平。

论强化消防部队管理执行力

安全事故频发,引发部队管理危机,究其原因是多方面的,但是,管理中的＂三弱化＂是主因。如何提升管理中的执行力,应从四个方面入手,即强化培训式管理、走动式管理、数字化管理、问责制管理。夯实执行根基,提升执行监管,量化执行标准,重施执行奖惩,确保消防部队管理执行力的提升,是减少安全事故,确保部队高度安全稳定的根本途径。     

既有锈蚀RC梁剩余抗剪承载力试验

为了准确评估锈蚀RC梁的剩余抗剪承载力,在对6根既有纵筋、箍筋锈蚀都比较严重的混凝土抗弯构件进行了剩余抗剪承力试验研究的基础上,提出了锈蚀RC梁的剩余抗剪承载力计算公式.结果表明,既有锈蚀RC梁挠度曲线没有明显的开裂拐点;破坏时脆性明显,裂缝集中在某一处,间距较大,破坏荷载和屈服荷载接近,受剪破坏形态可能表现为加载点下垂直裂缝引起的破坏.所提出的既有锈蚀RC梁剩余抗剪承载力计算公式与试验结果吻合较好,可为锈蚀RC梁剩余抗剪承载力评估提供一定参考.     

新疆边境地区反恐情报保障问题研究

反恐情报保障是反恐行动的重要组成部分和决策依据。针对新疆边境地区情报力量建设较弱、情报保障手段单一、与有关部门缺乏有效的交流机制等问题,公安边防部门应采取加强情报力量建设、完善情报保障机制、充分利用各种情报手段和加强情报交流与合作等有效措施,不断提高反恐情报保障能力,掌握反恐怖斗争的主动权。

浅析储油罐安全容量的确定计算

由于油料具有热膨胀性,在运输和储存期间,如果油罐装油超过安全容量,当温度升高时,罐内油料体积膨胀,就可能导致溢油事故的发生,不仅造成油料数量的损失,甚至会引发火灾事故。正确确定不同油罐的安全容量,对油料的安全具有重要意义。文章阐述了油罐安全容量的概念,分析了安全容量计算不准确可能造成的危害,提出了油罐安全容量的计算方法。     

Dynamic capacity reservation and due date quoting in a make‐to‐order system

We consider a make‐to‐order manufacturer facing random demand from two classes of customers. We develop an integrated model for reserving capacity in anticipation of future order arrivals from high priority customers and setting due dates for incoming orders. Our research exhibits two distinct features: (1) we explicitly model the manufacturer's uncertainty about the customers' due date preferences for future orders; and (2) we utilize a service level measure for reserving capacity rather than estimating short and long term implications of due date quoting with a penalty cost function. We identify an interesting effect (“t‐pooling”) that arises when the (partial) knowledge of customer due date preferences is utilized in making capacity reservation and order allocation decisions. We characterize the relationship between the customer due date preferences and the required reservation quantities and show that not considering the t‐pooling effect (as done in traditional capacity and inventory rationing literature) leads to excessive capacity reservations. Numerical analyses are conducted to investigate the behavior and performance of our capacity reservation and due date quoting approach in a dynamic setting with multiple planning horizons and roll‐overs. One interesting and seemingly counterintuitive finding of our analyses is that under certain conditions reserving capacity for high priority customers not only improves high priority fulfillment, but also increases the overall system fill rate. © 2008 Wiley Periodicals, Inc.
