This book provides a comprehensive demonstration of risk analysis as a distinct science covering risk understanding, assessment, perception, communication, management, governance and policy. It presents and discusses the key pillars of this science, and provides guidance on how to conduct high-quality risk analysis. The Science of Risk Analysis seeks to strengthen risk analysis as a field and science by summarizing and extending current work on the topic. It presents the foundation for a distinct risk field and science based on recent research, and explains the difference between applied risk analysis (to provide risk knowledge and tackle risk problems in relation to for example medicine, engineering, business or climate change) and generic risk analysis (on concepts, theories, frameworks, approaches, principles, methods and models to understand, assess, characterise, communicate, manage and govern risk). The book clarifies and describes key risk science concepts, and builds on recent foundational work conducted by the Society for Risk Analysis in order to provide new perspectives on science and risk analysis. The topics covered are accompanied by cases and examples relating to current issues throughout. This book is essential reading for risk analysis professionals, scientists, students and practitioners, and will also be of interest to scientists and practitioners from other fields who apply risk analysis in their work.

A bicycle-sharing system (BSS) has been implemented in Seoul, South Korea to promote green transportation policy as a Sustainable Development Goal (SDG) to mitigate climate change, reduce traffic jams, and promote physical activity. However, the concentration of air pollutants in Seoul often exceeds the standards of the World Health Organization, thereby creating a conflict with SDG 3 (Health). Therefore, it is important to recognize the trade-offs between actions targeted at SDGs as they might offset each other. In this context, a primary concern is investigating how the behavior of BSS users regarding outdoor air pollution appears. This study explores the relationship between ambient air pollution and the behavior of BSS riders in Seoul. We conducted a time-series analysis of associations between particulate air pollution and participation in the BSS. We used generalized additive models, adjusted for mean temperature, humidity, rainfall, day of the week, long-term trends, and seasonality to construct an exposure–response relationship. We observed a nonlinear relationship between increasing air pollution and bicycle ridership. This study method can be used as a basis for similar analyses to investigate BSS policies in other cities.

Quality of life and well-being are hardly ever an issue when life itself is at stake. The advantages of high-quality walkable streets and public spaces are underestimated when larger problems need to be addressed first and seemingly more serious solutions need to be applied. Hence, a quantitative approach to evacuation route planning and design prevails over a qualitative one or at least a hybrid one. The scope of the ongoing study partially presented in this paper is to find methods for addressing the complicated present and the disastrous future at the same time. The one applied in the case study reported here—Susaki City in Kōchi Prefecture, Japan, which is preparing for the next Nankai earthquake and tsunami, expected sometime soon—was a cycle of active research and international workshops organized in cooperation with the local community and administration. The aim was to understand the challenges that concern the design of dual spaces that are suitable for both everyday life and emergency situations and are connected by walkable spaces. As a result, the paper offers insight into the limits of punctual treatments as well as the relativity of objective and subjective dimensions of urban walkability in the context of risk. Despite the complexity of the issue, a walkable built environment was revealed to be a countermeasure rather than a fad.

The citizens of the Marshall Islands have been told that climate change will doom their country, and they have seen confirmatory omens in the land, air, and sea. This book investigates how grassroots Marshallese society has interpreted and responded to this threat as intimated by local observation, science communication, and Biblical exegesis. With grounds to dismiss or ignore the threat, Marshall Islanders have instead embraced it; with reasons to forswear guilt and responsibility, they have instead adopted in-group blame; and having been instructed that resettlement is necessary, they have vowed instead to retain the homeland. These dominant local responses can be understood as arising from a pre-existing, vigorous constellation of Marshallese ideas termed 'modernity the trickster': a historically inspired narrative of self-inflicted cultural decline and seduction by Euro-American modernity. This study illuminates islander agency at the intersection of the local and the global, and suggests a theory of risk perception based on ideological commitment to narratives of historical progress and decline.

The awareness of healthcare practitioners concerning heated tobacco product (HTP) use risks has been evaluated; however, few studies have investigated general dental practitioners’ awareness regarding HTP-use risks. In this cross-sectional study, we investigated dentists’ awareness of the risks of smoking, particularly HTP use. A self-administered questionnaire, including eight questions on conventional cigarette and HTP smoking/using status and both knowledge and awareness of HTP-use risks, was posted to 3883 dentists belonging to the Aichi Dental Association, Japan, in August 2019. Statistical analysis was performed using the Statistical Package for Social Sciences; statistical significance was set at p < 0.05. We analyzed the data of 1317 dentists (participation rate, 41.6%). The study group included cigarette smokers (11.5%) and HTP users (8.5%), among whom 41.1% were dual users. HTP users were more likely than never smokers/users to correctly perceive HTP-use risks (p < 0.05). This study indicates that in Japan, the proportion of HTP users is higher than that of the general population. It is important to educate not only smokers/users but also never smokers/users on the risks of smoking and using HTPs. Smoking cessation, including ceasing HTP use, and aiming to quit smoking and HTP use among dentists would contribute to appropriate smoking cessation among patients.

In Justice in the Risk Society Barbara Hudson outlines traditional liberal perspectives on justice, risk and security, as well as addressing some key concerns. The book provides theoretical analysis with a discussion of policies, and arguments are illustrated by cases and examples.

During the coronavirus disease (COVID-19) pandemic, engagement in preventive behaviors and getting tested for the virus play a crucial role in protecting people from contracting the new coronavirus. This study aims to examine how internet use, risk awareness, and demographic characteristics are associated with engagement in preventative behaviors and testing during the COVID-19 pandemic in the United States. A cross-sectional survey was conducted on Amazon Mechanical Turk from April 10, 2020, to April 14, 2020. Participants' internet use (in terms of the extent of receiving information pertaining to COVID-19), risk awareness (whether any immediate family members, close friends or relatives, or people in local communities tested positive for COVID-19), demographics (sex, age, ethnicity, income, education level, marital status, and employment status), as well as their engagement in preventative behaviors and testing were assessed. Our data included 979 valid responses from the United States. Participants who received more COVID-19-related health information online reported more frequent effort to engage in all types of preventive behaviors: wearing a facemask in public (odds ratio [OR] 1.55, 95% CI 1.34-1.79, P<.001), washing hands (OR 1.58, 95% CI 1.35-1.85, P<.001), covering nose and mouth when sneezing and coughing (OR 1.78, 95% CI 1.52-2.10, P<.001), keeping social distance with others (OR 1.41, 95% CI 1.21-1.65, P<.001), staying home (OR 1.40, 95% CI 1.20-1.62, P<.001), avoiding using public transportation (OR 1.57, 95% CI 1.32-1.88, P<.001), and cleaning frequently used surfaces (OR 1.55, 95% CI 1.34-1.79, P<.001). Compared with participants who did not have positive cases in their social circles, those who had immediate family members (OR 1.48, 95% CI 8.28-26.44, P<.001) or close friends and relatives (OR 2.52, 95% CI 1.58-4.03, P<.001) who tested positive were more likely to get tested. Participants' sex, age, ethnicity, marital status, and employment status were also associated with preventive behaviors and testing. Our findings revealed that the extent of receiving COVID-19-related information online, risk awareness, and demographic characteristics including sex, ethnicity, age, marital status, and employment status are key factors associated with US residents' engagement in various preventive behaviors and testing for COVID-19.

Enhancing the capacity and awareness of individuals in disaster prevention and mitigation requires an intuitive and comprehensible method for representing flood hazard education knowledge. To address the challenges of complex information transfer and limited knowledge expression in flood disaster education, this paper proposes a novel strategy. The approach utilizes conceptual graphs to organize and guide the visual representation of flood disaster knowledge. It involves connecting flood data and knowledge elements using concept nodes and relationships, and translating them into dynamic visual representations through instantiation methods. A prototype system was developed to visualize disaster data obtained from flood-affected areas. The visualization output was compared to expert-based reports using a questionnaire, focusing on attractiveness and comprehensibility. The results demonstrated the superiority of our approach, with higher scores of 0.433 and 0.22 (on a scale of 0–1) for attractiveness and comprehensibility, respectively. This highlights the effectiveness of our approach in displaying flood knowledge and facilitating its dissemination. In summary, this paper introduces a comprehensive and dynamic visualization approach for the entire flood process, integrating relevant disaster knowledge. It presents a fresh perspective on digital disaster education tailored to floods, aiming to enhance public awareness of flood risk prevention.
