Right Intention and the Ends of War

The jus ad bellum criterion of right intention (CRI) is a central guiding principle of just war theory. It asserts that a country’s resort to war is just only if that country resorts to war for the right reasons. However, there is significant confusion, and little consensus, about how to specify the CRI. We seek to clear up this confusion by evaluating several distinct ways of understanding the criterion. On one understanding, a state’s resort to war is just only if it plans to adhere to the principles of just war while achieving its just cause. We argue that the first understanding makes the CRI superfluous, because it can be subsumed under the probability of success criterion. On a second understanding, a resort to war is just only if a state’s motives, which explain its resort to war, are of the right kind. We argue that this second understanding of the CRI makes it a significant further obstacle to justifying war. However, this second understanding faces a possible infinite regress problem, which, left unresolved, leaves us without a plausible interpretation of the CRI. This constitutes a significant and novel reason for leaving the CRI out of the international law of armed conflict (LOAC).     

融合战术与修正物理特征的空中目标战术类型识别

针对敌方飞行器隐身、伪装技术的日趋成熟,致使我方由侦察设备获取的电磁信号严重变形,特别是物理特征在目标类型识别中的作用日趋减弱的现实问题,提出了一种融合目标战术特征修正物理特征证据的目标战术类型识别方法。该方法从目标战术类型识别的军事需求出发,提出对冲突物理特征证据的阶梯式修正规则,以及对冲突证据折扣因子的优化方法,并将修正后的证据重新组合得到识别结果。仿真实例证明该方法在处理目标冲突物理特征证据时具有高准确率的特点。该方法为复杂环境下的目标战术类型识别问题提供一种新的解决思路。     

Competing with channel partners: Supply chain conflict when retailers introduce store brands

Private‐label products are of increasing importance in many retail categories. While national‐brand products are designed by the manufacturer and sold by the retailer, the positioning of store‐brand products is under the complete control of the retailer. We consider a scenario where products differ on a performance quality dimension and we analyze how retailer–manufacturer interactions in product positioning are affected by the introduction of a private‐label product. Specifically, we consider a national‐brand manufacturer who determines the quality of its product as well the product's wholesale price charged to the retailer. Given the national‐brand quality and wholesale price, the retailer then decides the quality level of its store brand and sets the retail prices for both products. We find that a manufacturer can derive substantial benefits from considering a retailer's store‐brand introduction when determining the national brand's quality and wholesale price. If the retailer has a significant cost disadvantage in producing high‐quality products, the manufacturer does not need to adjust the quality of the national‐brand product, but he should offer a wholesale price discount to ensure its distribution through the retailer. If the retailer is competitive in providing products of high‐quality, the manufacturer should reduce this wholesale price discount and increase the national‐brand quality to mitigate competition. Interestingly, we find the retailer has incentive to announce a store‐brand introduction to induce the manufacturer's consideration of these plans in determining the national‐brand product quality and wholesale price. © 2010 Wiley Periodicals, Inc.

一种消除直线永磁无刷直流电机边端效应对换相时机影响的方法

电磁弹射用直线永磁无刷直流电机的永磁体动子具有开断结构,使动子边端的磁场分布发生变形。当采用霍尔元件检测磁场实现换相时,这种边端效应就会影响换相时机。分析了这类电机的换相机理和动子开断结构对换相时机的影响,指出这类边端效应受极弧系数影响显著,并提出了利用不对称滞环比较器或简易单限比较器对霍尔输出信号进行处理从而消除这类边端效应影响的方法,实验验证了简易单限比较器方案的可行性。     

基于随机搜索策略的中继卫星调度方法

高质量的调度方案不仅能满足用户的需求,还能为中继卫星系统的计划编制提供科学的决策手段和依据。针对日益多样化的用户需求,采用全新的中继卫星调度应用模式,允许用户提交多个可以滑动的时间窗口。面向这种调度模式,考虑中继业务中任务调度的灵活性和任务间的冲突,构建考虑多滑动窗口的中继卫星调度模型,并设计基于随机搜索策略的中继卫星调度算法。算法包括任务资源匹配与邻域生成、可用时间段生成、任务冲突分析、邻域搜索与冲突消解以及资源与任务集更新5个算子。通过仿真实验将该算法与基于时间自由度的启发式算法进行对比,验证了算法的有效性。     

The Prickly Thorn: A Re-evaluation of Orde Wingate and the Special Night Squads

Orde Wingate’s Special Night Squads played a key role in defeating the Great Arab Revolt of 1936–1939. Wingate’s Night Squads were distinctive in their approach to counter-insurgency warfare; in addition to bringing Arab insurgents to battle, the Night Squads proved their mettle by ‘flying the flag’ and by improving cooperation between Jewish settlers and British servicemen. Nevertheless, the Night Squad’s accomplishments and legacy must be properly situated within the broader wave of tactical innovations undertaken by the British Army throughout the Rebellion.

The importance of predecessor centers of sovereignty and processes of state formation in explaining secession

A range of theories have sought to explain and predict secession with varying degrees of success. Arguing that a disproportionate focus upon the seceding group as the unit of analysis has frustrated the development of a comprehensive theoretical framework that is universally valid, this article highlights the role of predecessor institutions of governance and the failure of states to successfully incorporate these as an important, but neglected, causal factor in the study of secession. The inclusion of pre-state institutions of governance and processes of state formation not only results in a more complete, and therefore accurate, explanatory account of secession, but also explains why some regions have been more prone to secession than others.
