The University of Chicago Project on Security and Threats presents the updated and expanded Database on Suicide Attacks (DSAT), which now links to Uppsala Conflict Data Program data on armed conflicts and includes a new dataset measuring the alliance and rivalry relationships among militant groups with connections to suicide attack groups. We assess global trends in suicide attacks over four decades, and demonstrate the value of the expanded DSAT with special attention to the growing diffusion of suicide attacks in armed conflicts and the large role of networks established by Al-Qaeda and the Islamic State through 2019 in this diffusion. Overall, the expanded DSAT demonstrates the advantages of integration across datasets of political violence for expanding research on important outcomes, generating new knowledge about the spread of particularly deadly forms of political violence, and raising important new questions about the efficacy of current policies to curb their spread.

芝加哥大学安全与威胁项目提出了更新和扩展的自杀攻击数据库（DSAT），该数据库现在链接到关于武装冲突的Uppsala冲突数据计划数据，并且包括一个新数据集，该数据集衡量了有联系的激进组织之间的联盟和对抗关系自杀袭击团体。我们评估了四十年来全球自杀式袭击的趋势，并展示了DSAT扩展后的价值，特别关注武装冲突中自杀式袭击的日益扩散以及基地组织和伊斯兰国在2019年之前建立的网络的巨大作用。这种扩散。总体而言，扩展后的DSAT展示了跨政治暴力数据集进行整合对于扩展重要成果研究的优势，
