Authoritarianism and the Emergence of Parallel State Dynamics: Evidence From the Syrian Earthquake
Digest of Middle East Studies, Volume 34, Issue 1, Winter 2025.ABSTRACT This article investigates the Syrian regime's strategic manipulation of the February 2023 earthquake to reaffirm its authority and maintain legitimacy. The regime's response to the disaster is analyzed to understand how authoritarian states leverage natural disasters for political gains. It argues that the Assad regime's survival is not merely

Gaoya dianqi, 2017 文中采用建模和仿真方法对安装于某水电厂的某一带气动操动机构的330 kV GIS断路器分、合闸操作异常振动问题展开研究。首先,建立了带气动操动机构断路器的运动模型,仿真分析了其操作时的振动特性及气动机构工作气压变化对振动特性的影响。然后,又对带液压操动机构断路器操作时的振动特性展开了建模和仿真分析。部分仿真结果也与试验结果进行了对比,能够较好吻合。通过对带两种不同操动机构断路器振动特性仿真结果的对比发现:液压操动机构断路器的振动强度比气动机构的要小,而且液压机构断路器振动强度的衰减速度更快 ...

Local lobbying in single‐party authoritarian systems: Do institutions matter?
Review of Policy Research, Volume 41, Issue 6, Page 921-940, November 2024.Abstract Lobbying, and its role in the policy process, has been extensively studied in democratic states, but much less is known about similar practices in authoritarian political systems. Although a few studies have identified lobbying in China, most have focused on big businesses and national policy making, and some have argued that it is unaffected ...

Gaoya dianqi, 2014 提出一种真空断路器弹簧操动机构故障的分析方法。针对FZW型真空断路器的弹簧操动机构,用Solidworks实体造型软件建立了弹簧操动机构的三维实体模型。阐述了弹簧刚度系数和阻尼的确定方法,并确定了机构中的弹簧及其他构件的参数。最后对弹簧操动机构进行运动学仿真,从各主要构件的运动情况和受力情况中分析了弹簧操动机构可能出现的故障以及防范措施。结果表明,构建弹簧操动机构的实体模型进行运动仿真分析,可以为真空断路器的故障分析提供依据。
