Coercive diplomacy and the Donbas: Explaining Russian strategy in Eastern Ukraine

What were Russia’s objectives in Eastern Ukraine, and why was it seemingly unable to achieve a successful or decisive outcome? In contrast to Russia’s seizure of Crimea, the uprising in Eastern Ukraine was marked by disorganization and chaos. Using proxy and surrogate actors, along with military exercises and the injection of Russian troops, Russia sought to institutionalize a political entity inside Ukraine to influence its domestic politics. In this article, I analyze the mechanisms by which Russia attempted to implement, and later salvage, its strategy. The article contributes to clearer theoretical and practical understanding of limited force in coercive diplomacy, signaling, and a more rigorous treatment of the role and uses of proxy actors.     

横向效应增强型弹垂直侵彻薄靶的轴向剩余速度理论分析

为了得到横向效应增强型弹（Penetration with Enhanced Lateral Efficiency projectile, PELE）对金属薄靶垂直侵彻后的弹体轴向剩余速度,运用平面冲击波理论,对PELE的侵彻机理进行分析。参照平头弹体对靶板的侵彻模型,将PELE侵彻过程中的能量损失划分为以下几个部分：外壳体和内芯撞靶区域对应的环形塞块获得的能量、冲击波作用下弹体的内能增量以及剪切耗能等。然后根据能量守恒原理,得到PELE垂直侵彻金属薄靶后的PELE弹体轴向剩余速度的理论模型。为了验证该模型的合理性和准确性,设计相应的试验进行验证。结果表明,不同条件下得到的试验结果和理论模型得到的计算结果均吻合得较好。因此,得到的PELE垂直侵彻薄靶的轴向剩余速度理论模型可为工程应用提供指导和参考。

Development of proxy relationships: a case study of the Lebanese Civil War

Proxy warfare is a consistent element in international warfare. However, it is unclear why proxy relationships form in cases where states have multiple options of groups to support. Existing research identifies the presence of transnational constituencies, shared interstate rivalries, and moderate relative strength of militant groups as highly influential on the development of a proxy relationship. This study examines the presence of these variables within the context of the Lebanese Civil War. The results of this demonstrate that each state places greater importance on some variables and ignores others when choosing a proxy. Additionally, this study further demonstrates the presence of new variables that are key to the development of proxy relationships.     

Historical and Political Background to the Erosion of the Rule of Law and Human Rights During Sri Lanka’s Civil War and the Way Forward

The Sri Lankan Civil War (1983–2009) is regarded as a violent reflection of deepening divides along political and ethnic lines. During this civil war the Sri Lankan Government and its security forces have been implicated in unlawful killings carried out in a pervasive manner against civilians, whilst at the same time specifically targeting ethnic Tamils, humanitarian workers and journalists. The human rights of all citizens suffered as a result and ultimately led to the weakening of the rule of law. With the end of the civil war, the Sri Lankan Government has made little progress in providing accountability for wartime abuses. Its absence of and reluctance to ensure justice is seen as a logical culmination of decades of impunity. The importance of acknowledging historical behaviour and taking accountability for past violations will be discussed. In an analysis for paving the way to a new democracy in Sri Lanka, the main outcomes of this article are calls for accountability arising out of the government’s actions during the war; an investigation into the present state of human rights, the rule of law and finally; an examination into the political solution going forward to ensure a process of reconciliation and peaceful co-existence.     

基于灰色关联和D-S证据理论的导弹系统安全性评估

针对导弹系统安全性评价的不确定性问题,提出了将灰色关联和D-S证据理论相结合的方法,从人员安全性、设备安全性和环境安全性建立了综合评估指标体系,用灰色关联分析处理了指标之间的关联性。在传统证据合成公式的基础上,考虑证据集非关键因素的权重,给出了修正的证据合成公式。并以打靶选弹为例进行了计算分析,得出了导弹安全性优先级排序,并将改进算法与传统计算方法的结果进行了比较,验证了评价模型的可行性与实用性,为导弹系统的管理工作提供了有益的参考。     

基于Epsilon-Nash策略的动态武器-目标分配方法

在大型任务规划软件的作战单元任务分配中,搜索零和博弈问题的纳什均衡点是求解任务分配的一种有效的方法。然而,纳什均衡点在决策中并不一定总是存在且唯一,这造成了纳什均衡策略在实际使用时具有较大的局限。通过采用Epsilon-Nash策略克服这种局限,并将其应用于自主空战任务规划系统中,通过仿真实验,证实Epsilon-Nash策略具有近似于纳什策略的效果。
