摘要:

COVID-19大流行引发了多重公共卫生、社会经济和制度危机。为减缓病毒传播而采取的措施在当局和公民之间造成了严重的紧张关系,导致了一波又一波的社会动荡和反政府示威。我们研究了“COVID-19疾病追踪”计划所记录的大流行相关疾病事件的时间性质,重点关注事件数量最多的三个国家,印度,以色列和墨西哥。通过对数据流的泊松过程和霍克斯过程的拟合,我们发现,在这三个国家的无序事件是相互依赖和自激的。地理聚类证实了这些功能在国家以下一级,表明全国范围内的混乱出现的自我激励的中尺度模式的收敛。在计算国家以下各级群组之间事件的相关性时,观察到各国之间存在相当大的差异;这些差异是在具体的政治、社会和地理特征背景下讨论的。以色列是领土最紧凑的国家,也是为应对政府封锁而协调大规模抗议活动的国家,在事件发生后表现出最大的反应和最短的影响力,以及最强的全国同步性。在墨西哥,完全封锁命令从未被强制执行,反应性和全国同步性最低。我们的工作突出表明,当局需要促进地方宣传运动,以确保生计和病毒遏制政策不被视为相互排斥的。

英文摘要:

The COVID-19 pandemic has unleashed multiple public health, socio-economic, and institutional crises. Measures taken to slow the spread of the virus have fostered significant strain between authorities and citizens, leading to waves of social unrest and anti-government demonstrations. We study the temporal nature of pandemic-related disorder events as tallied by the "COVID-19 Disorder Tracker" initiative by focusing on the three countries with the largest number of incidents, India, Israel, and Mexico. By fitting Poisson and Hawkes processes to the stream of data, we find that disorder events are inter-dependent and self-excite in all three countries. Geographic clustering confirms these features at the subnational level, indicating that nationwide disorders emerge as the convergence of meso-scale patterns of self-excitation. Considerable diversity is observed among countries when computing correlations of events between subnational clusters; these are discussed in the context of specific political, societal and geographic characteristics. Israel, the most territorially compact and where large scale protests were coordinated in response to government lockdowns, displays the largest reactivity and the shortest period of influence following an event, as well as the strongest nationwide synchrony. In Mexico, where complete lockdown orders were never mandated, reactivity and nationwide synchrony are lowest. Our work highlights the need for authorities to promote local information campaigns to ensure that livelihoods and virus containment policies are not perceived as mutually exclusive.
