Agent-based models of human response to natural hazards: systematic review of tsunami evacuation

This systematic review provides a comprehensive overview of tsunami evacuation models. The review covers scientific studies from the last decade (2012-2021) and is explicitly focused on models using an agent-based approach. The PRISMA methodology was used to analyze 171 selected papers, resulting in over 53 studies included in the detailed full-text analysis. This review is divided into two main parts: (1) a descriptive analysis of the presented models (focused on the modeling tools, validation, and software platform used, etc.), and (2) model analysis (e.g., model purpose, types of agents, input and output data, and modeled area). Special attention was given to the features of these models specifically associated with an agent-based approach. The results lead to the conclusion that the research domain of agent-based tsunami evacuation models is quite narrow and specialized, with a high degree of variability in the model attributes and properties. At the same time, the application of agent-specific methodologies, protocols, organizational paradigms, or standards is sparse.

PTSD, burnout and well-being among rescue workers: Seeking to understand the impact of the European refugee crisis on rescuers

Individuals who perform rescue and recovery duties, as part of their daily work activities, confront diverse stressors that can affect their mental state and overall well-being. The study aimed to assess the prevalence and the factors associated with self-assessed PTSD, perceived well-being and burnout among rescue workers operating at Lesvos during the European refugees crisis. 217 rescuers participated in the study, while the PTSD Checklist-Civilian Version (PCL-C), the Maslach Burnout Inventory (MBI) and the Well-being Index (WHO-5) were utilized. The prevalence of self-assessed PTSD and perceived burnout syndrome was 17.1% and 57% respectively, while 72.8% of the rescuers reported low levels of perceived well-being. Self-assessed PTSD was positively correlated with perceived burnout and inversely correlated with perceived well-being. Perceived burnout was also inversely correlated with perceived well-being. A number of significant predictors were identified for self-assessed PTSD, perceived burnout and well-being, including: family status, age, duration of shifts, collection of dead adults or dead children bodies. The impact of the refugee crisis is visible on the rescue workers that offer rescue and first aid services. There is an urgent need for implementing effective interventions focusing on the identified determinants in order to enhance the occupational psychological burden of rescuers.

Assessing Mental Models of Emergencies Through Two Knowledge Elicitation Tasks

OBJECTIVE

The goals of this study were to assess the risk identification aspect of mental models using standard elicitation methods and how university campus alerts were related to these mental models.

BACKGROUND

People fail to follow protective action recommendations in emergency warnings. Past research has yet to examine cognitive processes that influence emergency decision-making.

METHOD

Study 1 examined 2 years of emergency alerts distributed by a large southeastern university. In Study 2, participants listed emergencies in a thought-listing task. Study 3 measured participants' time to decide if a situation was an emergency.

RESULTS

The university distributed the most alerts about an armed person, theft, and fire. In Study 2, participants most frequently listed fire, car accident, heart attack, and theft. In Study 3, participants quickly decided a bomb, murder, fire, tornado, and rape were emergencies. They most slowly decided that a suspicious package and identify theft were emergencies.

CONCLUSION

Recent interaction with warnings was only somewhat related to participants' mental models of emergencies. Risk identification precedes decision-making and applying protective actions. Examining these characteristics of people's mental representations of emergencies is fundamental to further understand why some emergency warnings go ignored.

APPLICATION

Someone must believe a situation is serious to categorize it as an emergency before taking the protective action recommendations in an emergency warning. Present-day research must continue to examine the problem of people ignoring warning communication, as there are important cognitive factors that have not yet been explored until the present research.
