The World Health Organization’s Guidance for Just-in-Time Learning as a Framework for Normatively Responsible Advocacy in Instructional Risk and Crisis Communication
are fitting with the four tenets of normatively responsible advocacy in instructional risk and crisis communication: (1) balancing cognitive, affective, and behavioral learning; (2) improvisation in designing instructional content; (3) agility in distribution of instructional content; and (4) meeting the normative needs and expectations of diverse audiences
Addressing Perceived Apathy Through Engaged Learning in Crisis Communication: Lessons From Bird Flu (H5N1) in Dairy
Recent outbreaks of A/H5N1 (Highly Pathogenic Avian Influenza virus/HPAIv) —commonly referred to as bird flu virus—have mutated and spread beyond poultry to also infect dairy cattle and humans. Despite warnings by crisis communication practitioners affiliated with the dairy industry, the response is widely criticized as underwhelming and apathetic. This study proposes engaged learning as an instructional risk and crisis co strategy for overcoming…
Emergency communication networks on Twitter during Hurricane Irma: Information Flow, Influential Actors, and Top Messages
This study combined network analysis with message-level content analysis to investigate patterns of information flow and to examine messages widely distributed on social media during Hurricane Irma of 2017. The results show that while organisational users and media professionals dominated the top 100 information sources, individual citizens played a critical role in information dissemination. Public agencies should increase their retweeting activ…
Engaged learning: Lessons learned by subject-matter experts from Covid-19 in the U.S. swine industry
When industries fail to address warnings adequately, risk situations may manifest into crises. Although the U.S. swine industry planned thoroughly for potential infectious disease outbreaks among the animal population, COVID-19 highlighted a planning gap: What happens if the humans working to keep the industry operational can no longer work? This oversight ultimately resulted in a crisis event impacting all aspects of the U.S. swine industry. Thi…
Communicating Risk and Safety
The world is wrought with risks that may harm people and cost lives. The news is riddled with reports of natural disasters (wildfires, floods, earthquakes, hurricanes), industrial disasters (chemical spills, water and air pollution), and health pandemics (e.g., SARS, H1NI, COVID19). Effective risk communication is critical to mitigating harms. The body of research in this handbook reveals the challenges of communicating such messages, affirms the…
Dynamics of interorganisational emergency communication on Twitter: The case of Hurricane Irma
This study examines how county-level emergency management offices (EMOs) used Twitter to communicate with other public agencies and non-profit and for-profit organisations before, during, and after Hurricane Irma in 2017. It assesses the strategies that EMOs and other stakeholders employed to communicate risks on Twitter, concluding that its potential has not been fully exploited. EMOs only frequently interacted with a few non-profit and for-prof…
Being First, Being Right, and Being Credible Since 2002: A Systematic Review of Crisis and Emergency Risk Communication (Cerc) Research
The crisis and emergency risk communication (CERC) model is a five-stage theory that merges established public health practices with principles of crisis communication. Although CERC has been regularly applied on the ground, it has been criticized as lacking the coherence and unity necessary to serve as a framework for research. To determine the extent and type of research CERC has generated since its original presentation to the academic communi…
Communities of practice as purveyors of instructional communication during crises
This study focuses on the critical role instructional communication plays in effective risk and crisis communication. More specifically, we examined efforts made by the United States’ swine industry to teach biosecurity practices in response to the African Swine Fever virus, a highly contagious novel disease. To do so, researchers interviewed 14 research, veterinary, and extension specialists to assess the swine industry’s capacity to function as…
No heat, no electricity, no water, oh no: An Idea model experiment in instructional risk communication
Instructional communication is a vital component of the risk communication process. Without adequate instruction, individuals are less likely to understand, value, and follow guidelines for protecting themselves and their loved ones. The IDEA model (internalization, distribution, explanation, and action), applied successfully in crisis communication, has shown promise for use in instructional risk communication, as well. More specifically, it may…
Challenges and opportunities for pre-crisis emergency risk communication: Lessons learned from the earthquake community
Prior to the 2009 L’Aquila event, earthquake forecasting and early warning research focused specifically on earthquakes as the crisis events. Although this is still true, the manslaughter convictions of six earthquake scientists and one public official for failed risk communication in 2009 served as a catalyst for expanding these goals to also intentionally examine the challenges of communicating earthquake risk with non-scientific during the pre…
Risk and crisis communication narratives in response to rapidly emerging diseases
The uncertainty inherent in crises can create a narrative space that is often filled by multiple interpretations about both what is happening and what steps should be taken to resolve the crisis. As more information becomes known, these competing crisis narratives gradually merge into a dominant narrative about the crisis, lessons learned from it, and recommendations for the future. This case study examines the swine industry’s response to the Po…
Exemplification effects: Responses to perceptions of risk
Exemplification theory asserts that message components that are iconic and emotionally arousing are easily accessed, and are therefore relied upon when making subsequent behavioral decisions. A reanalysis of data from three studies collected at different times, unrelated experimental stimuli (terrorism, food ingredients, and bed bugs), different media (visual and print), varying geographic locations, different experimental conditions (laboratory …
Theorizing Crisis Communication
Theorizing Crisis Communication presents a comprehensive review and critique of the broad range of theoretical frameworks designed to explain the role of communication in the development, management, and consequences of natural and man-made crises. This book: Brings together the variety of theoretical approaches emerging in the study of crisis communication into one volume for the first time ; Summarizes theories from such diverse perspectives as…
Effective Risk Communication: A Message-Centered Approach
Cerc as a Theoretical Framework for Research and Practice
Health communicators at the Centers for Disease Control and Prevention (CDC) have developed an integrated model titled Crisis and Emergency Risk Communication (CERC) as a tool to educate and equip public health professionals for the expanding communication responsibilities of public health in emergency situations. This essay focuses on CERC as a general theoretical framework for explaining how health communication functions within the contexts of…
Communication, Organization, and Crisis
Communication is increasingly recognized as an important process in organizational crisis and crisis management. The Three Mile Island incident, the Bhopal Union Carbide accident, the crash of Northwest Airlines Flight 255, and the Exxon Valdez oil spill can all be described as specific, unexpected, and nonroutine events or series of events that created high levels of uncertainty and threat or perceived threat to an organization's high-priority g…
