RT Article T1 Dynamic Patterns of Terrorist Networks: Efficiency and Security in the Evolution of Eleven Islamic Extremist Attack Networks JF Journal of quantitative criminology VO 36 IS 3 SP 559 OP 581 A1 McMillan, Cassie A2 Felmlee, Diane H. A2 Braines, Dave LA English YR 2020 UL https://krimdok.uni-tuebingen.de/Record/1738428028 AB The current research examines how the efficiency/security tradeoff shapes the evolution of dynamic terrorist networks by focusing on the structural properties of these collectives. Some scholars argue that terrorist groups develop as chain-like, decentralized structures, while others maintain that terrorist networks form patterns of redundant ties and organize around a few highly connected individuals, or central hubs. We investigate these structural properties and consider whether patterns vary at different phases of a terrorist network’s formation.
