恐怖袭击间隔时间的标度性质及意见模型
Scaling property and opinion model for interevent time of terrorism attack
摘要：
通过实证数据和模型分析，对恐怖袭击事件的间隔时间进行了研究。经验证据表明，它遵循无标度性质。为了理解这种统计特征的动力学机制，在二维格点网络上建立了一个具有记忆效应的意见动力学模型。该模型主要突出了个体社会从众心理和自我肯定心理的作用。当系统的序参量达到一个临界值时，就发生了攻击事件。最终，该模型再现了与经验数据相同的统计特性，并给出了一个很好的理解恐怖袭击。
英文摘要：
The interevent time of terrorism attack events is investigated by empirical data and model analysis. Empirical evidence shows it follows a scale-free property. In order to understand the dynamic mechanism of such statistic feature, an opinion dynamic model with memory effect is proposed on a two-dimension lattice network. The model mainly highlights the role of individual social conformity and self-affirmation psychology. An attack event occurs when the order parameter of the system reaches a critical value. Ultimately, the model reproduces the same statistical property as the empirical data and gives a good understanding of terrorism attack.
