Abstract
In this special edition of the Journal of Security, Intelligence, and Resilience Education, scholars from American colleges and universities explore the relationship between theory and practice in homeland security, intelligence, law enforcement, emergency management, and public health. The edition features the guided perspectives of eleven contributors who delve into singular and multi-theoretical frameworks and an atheoretical approach to research and practice. This introductory issue provides a brief overview of the articles that cover critical issues, including complex adaptive systems, crisis management, disaster preparedness, experiential learning, homeland security, international relations, intersectionality, natural disasters, organizational culture, public health threats, terrorism, translational research, and vulnerable populations.
