‘What is in a Name?’: The Role of (Different) Identities in the Multiple Proxy Wars in Syria

Abstract

Post-uprisings Middle East politics is frequently described as a ‘regional cold war’ involving proxy warfare that emphasises the role of shared identities linking external and local actors. But does the ‘content’ of identities impact proxy war dynamics? This article considers the present ‘battle for Syria’, a local conflict that became a theatre for multiple proxy wars involving actors emphasising identities on various levels, most notably national, religious/ sect and ethnic. It suggests that identity content does matter, with global powers more reluctant than regional players to back groups identifying at sub-national level, while foreign non-state actors are enthusiastic backers of sub-national identity.     

面向SDR应用的向量存储器的设计与优化

针对面向SDR应用的SIMD数字信号处理器高带宽数据访存需求,提出并实现了一种新型的向量存储结构.该向量存储器由16路向量存储块构成,每路采用两组多体低位地址交叉编址存储结构,减少了访存体冲突,充分利用多存储体带宽,以较小的功耗代价实现并行访问多个向量数据.在此基础上,还设计了一种向量访存重整理单元,使向量存储器可灵活支持多路SIMD结构向量处理单元的非对齐访问,实现了其对向量存储器的共享.测试结果表明,该向量存储器能有效减少或消除向量处理单元之间的数据混洗操作,加速相关应用算法.     

多属性融合的坦克分队作战效能评估

现代条件下战场情况复杂,影响作战效能的因素众多且具有不确定性,为了获得对作战效能更为准确,可靠的评价,构建了一种新的基于多属性融合的坦克分队作战效能评估模型。结合已有的证据理论改进算法,给出了一种新的解决冲突证据的组合规则,并提出了一种新的组合策略,将其应用于评估模型中定性指标的融合;通过线性与非线性综合加权的方法求得评价的综合分值,得出了最终的评估结果。通过实例表明,该模型符合评估实际,对多属性模型的评估具有一定的借鉴意义。

针对传感器管理中目标—传感器配对出现的目标优先级求解问题,提出了一种基于Vague集的TOPSIS计算方法。在分析目标优先级的主要影响因素基础上,定义了各影响因素的影响系数。同时结合Vague集的TOPSIS法给出了目标优先级的计算步骤,为目标优先级求解提供了一种新途径。并结合仿真算例表明该方法的合理性与有效性。     

基于三次B样条曲线的一维弹道修正弹空气阻力系数拟合

为提高弹道修正弹的射击精度,对一维弹道修正弹空气阻力系数的拟合方法进行了研究。在分析Logistic曲线对43年阻力定律拟合缺点的基础上,提出了一种采用三次B样条曲线对其进行拟合的新方法。并通过某型号一维弹道修正弹验证了该拟合方法具有可行性好、拟合精度高、运算简单、结果可靠等优点。该拟合方法的提出为一维弹道修正弹空气阻力系数的拟合提供了一种新的研究方法,更便于外弹道的仿真计算。     

The resource-conflict debate revisited: Untangling the case of farmer–herdsman clashes in the North Central region of Nigeria

The resource debate is easily discerned as part of the ongoing history of farmer–herdsman conflict in the North Central region of Nigeria. Scarcity theorists are adept at linking scarcity with the onset of livelihood conflict while on the other hand resource abundance pundits insist it is profusion and not scarcity that impels conflict. This article traverses these wrangles and proceeds to downplay the resource polemic altogether. It is proposed that the resource debate, despite its profoundness, presents a narrow reading of farmer–herdsman clashes in Nigeria’s North Central region. It is suggested that a number of other factors, including elite land grabbing, ethno-religious identity construction, weak state capabilities, the citizenship question, corrupt traditional institutions, the lack of an effective land tenure system and a widespread culture of impunity, make for better readings of the conflict. Owing to the negative impacts of the conflict on state and society, it is recommended that the state in Nigeria should commit itself to addressing the citizenship question, strengthening the capabilities of security institutions, extirpating the culture of impunity and revaluing its policy on land redistribution.
