In his dissertation 'Co-creating Safety and Security: Essays on bridging disparate needs and requirements to foster safety and security', Mark van der Giessen aimed to advance our understanding of how various actors with their disparate needs and requirements can collaboratively foster safety and security. Safety and security contexts are diverse, ranging from the widespread daily policing practices involving local governments, law enforcement and community groups, to highly extreme and complex local responses to grand challenges, such as the professionals, volunteers and local communities responding to a refugee crisis. Regardless of the specific context however, practitioners and management scholars do not yet have the tools and knowledge to address how the actors involved, engaging from different backgrounds and with their own needs and requirements, may collaboratively foster safety and security.
