Background: The structure of trauma narratives is considered to be related to posttraumatic stress symptomatology and thus the capacity to make a coherent narrative after stressful events is crucial for mental health.

Abstract

Lone-actor terrorism is not a new phenomenon; however, research suggests the threat is increasing as pressure from security services forces a tactical adaptation and groups call on those who share their ideology to act alone without direction or support. This paper is the first publication in the Countering Lone-Actor Terrorism (CLAT) project, which aims to improve understanding of, and responses to, the phenomenon of (potentially) violent lone actors through analysis of comprehensive data on cases from across Europe.

The aim of this article is to provide a systematic review of peer-reviewed literature on leadership tasks and effectiveness of mayors and governors during drastic collective events. A total of 34 peer-reviewed articles met our criteria. They were analysed using the theoretical framework by Boin on leadership tasks, i.e., sense making, decision making, meaning making, terminating, and learning. Studies ranged from minor incidents like local riots, to the events of 9/11 and Hurricane Katrina. The material turned out to be dominated by Western and American studies.
