“…A review of crisis management literature indicates that the majority of the studies were concerned with the "core" actors, that is, different types of professional preparedness and emergency services (Andersson, Carlstrom, Ahgren, & Berlin, 2014;Berlin & Carlstr€ om, 2009;Jerzy, 2016) and organizations working in high-reliability environments (Hales & Chakravorty, 2016;Mousavi et al, 2018;Roberts & Bea, 2001).
