The long and winding road … to success? Unit peace operation effectiveness and its effect on mission success

Why does peacekeeping sometimes fail? How can effective peacekeepers increase the likelihood of success of a mission? The two main flaws in the current evaluations of peace operations are that they mainly rely on already concluded missions and that they make use of indicators that do not reveal micro-level dynamics. This article introduces an analytical framework relating the effectiveness of soldiers to their actual impact in their area of operation in a peace operation. The framework is called “unit peace operation effectiveness” (UPOE). Focusing on soldiers in peace operations, this article shows that: different units behave differently; emphasize different aspects of the mandate; and are effective in different ways. Ultimately, this has an actual impact on the end-state of the mission. It relies on and adapts classic security studies works to theoretically enrich the peacekeeping literature. The model is tested in an illustrative case study based on ethnographic work on French and Italian units in Afghanistan between 2008 and 2010.

Maintaining peace in a neighbourhood torn by separatism: the case of Satun province in southern Thailand

While separatist-related conflict has re-emerged in southern Thailand, there is one predominantly Muslim border province that has remained outside of the conflict. Satun province has been conspicuously unaffected by the Malay-Muslim separatist movement, despite its shared history and ethnic origins with the conflict-affected provinces. In contrast to Pattani, Yala, and Narathiwat, the process of state penetration in Satun was gradual and comparatively less coercive, leading to relative stability and encouraging political and economic integration. This comparative study analyzes the history of cooperative state–minority relations and political stability in Satun province, and draws important lessons directly applicable to the unrest in neighbouring provinces.

弹道导弹大气层外飞行时间长且弹道固定,易被敌方预测和拦截。针对以上问题,本文提出一种最优脉冲式变轨方法,该方法设计的弹道由2条不同的椭圆弧段组成,成功命中目标的同时,增加了敌方的拦截难度。以机动变轨所需能量和变轨后飞行剩余时间的加权最优为性能指标,设计了利用遗传算法在初始弹道上寻求最优变轨点的方法。最后,将遗传算法搜索最优点结果与遍历搜索结果进行对比,其最大误差为 ,从而验证了遗传算法在应用于导弹变轨问题,用以寻求最优变轨点是准确有效的。

钢管在冲击荷载作用下的变形与失效破坏

为研究钢管在弹体侵彻过程中的变形特点,基于ANSYS/LS-DYNA软件,采用Johnson-Cook模型,模拟了半球形弹体以不同速度正向冲击钢管时的非线性动力响应情况。结果表明：弹体速度越小,钢管的抗侵彻性能越好;弹体速度越接近临界破坏速度,钢管降低弹体速度的能力就越明显;弹体冲击钢管时,钢管上表面比下表面更容易产生大变形,消耗更多的弹体动能,并在抗侵彻过程中伴有局部凹陷、蝶形变形和贯穿现象。实验结果可为圆柱壳结构钢管在冲击荷载作用下的耗能分析提供参考。
