With the potential increase in hurricane intensity in changing climate conditions, hurricane impacts are expected to worsen. Current hurricane risk management practices are based on the hurricane risk assessment without considering climate impact, which would result in a higher level of risk for the built environment than expected. It is crucial to investigate the impact of climate change on hurricane risk to develop effective hurricane risk management strategies. However, investigation of future hurricane risk can be very time-consuming because of the high resolution of the models for climate-dependent hazard simulation and regional loss assessment. This study aims to investigate the climate change impact on hurricane wind risk on residential buildings across the southeastern US coastal states. To address the challenge of computational inefficiency, we develop surrogate models using machine learning techniques for evaluating wind and rain-ingress losses of simulated climate-dependent hurricane scenarios. We collect historical hurricane data and use selected climate variables to predict changing hurricane attributes under climate change. We build the surrogate loss model using data generated by the existing fragility-based loss model. The loss estimation of synthetic events using the surrogate model shows an accuracy with a 0.78 R-squared value compared to Hazard U.S. - Multi Hazard (HAZUS-MH) estimation. The results demonstrate the feasibility of utilizing surrogate models to predict risk changes and underline the increasing hurricane wind risk due to climate change.</p>","PeriodicalId":21472,"journal":{"name":"Risk Analysis","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144120810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Earlier studies offer only a partial and indirect explanation as to why variations in WTP exist. We evaluated whether psychological factors of risk-taking tendencies, attitudes toward uncertainty, sense of regret, and demographic variables, particularly experience and gender, might clarify the disparities in an anesthetist's WTP. Anesthetists from two National Health Service Trusts in England (i.e., hospitals) viewed, in random order, three different realistic scenarios (representing low-, medium-, and high-risk cases) and were asked to indicate how likely they were to agree to proceed as the attending anesthetist. They also answered questions evaluating their risk-taking tendencies, comfort with uncertainty, and tendency to experience regret. Anesthetists varied in their WTP. Importantly, our data revealed that a sense of uncertainty and regret, but not a risk attitude, could help explain these variations. Female anesthetists were less likely to agree to proceed as attending anesthetists regardless of the level of risk or individual differences, but we found no relationship between levels of experience and WTP. Examining anesthetists' WTP in isolation provides an important but only partial picture. Gaining a better understanding of the factors that drive decision-making is vital for improving both training and practice.

In the aviation domain, the two different roles of crews in the cockpit-pilot flying (PF) versus pilot monitoring (PM)-are responsible for different tasks. However, little is known about how role assignment shapes pilots' perceived risk. We designed a flight-simulation experiment where 57 professional pilots completed two counterbalanced approaches under different role assignments with the assistance of a flight instructor in a full flight simulator. Their perceived risks were measured by psychophysiological responses and compared between the two different cockpit roles. Results indicate that participants exhibited stronger psychophysiological responses (e.g., higher subjective ratings, skin conductance responses, heart rates, and inter-beat intervals) when they served as PF than PM. Particularly, they reported higher scores in affect, susceptibility, and severity dimensions as PF than PM. The asymmetrically psychophysiological responses between the two varying roles in the cockpit emphasize the importance of controllability in shaping the pilot's perceived risk.

To evaluate human reliability quantitatively and accurately, this study proposes a comprehensive cognitive reliability and error analysis method (CREAM). First, the weighting factors of different common performance conditions (CPCs) under uncertain conditions are derived by integrating the modified decision-making trial and evaluation laboratory-based analytic network process with linguistic D numbers. Second, considering the joint effects of cognitive performance and operational environment on crew behaviors, a cognitive performance adjustment coefficient is introduced to improve the conventional CREAM method. Third, group best-worst method and best-worst method based on nonlinear goal programming are used to determine the weighting factors of human intrinsic factors (HIFs). The results of the cross-platform combat task simulation show that the cumulative human error probability (HEP) of crews by this method is estimated as 26%, while the average HEP of the other HRA methods is approximately 24%. The HEP value has improved by 7% on average. The failure in judgment is the most critical contributor to human errors. Finally, according to the sensitivity analysis, the HEPs in different task processes with various CPCs and HIFs have significant differences (p < 0.01). The effect of the change in CPCs on the quantitative assessment of HEPs remains much steadier than that of the HIFs. The proposed method provides an effective method for the quantitative evaluation of human failure probabilities for crews in combat missions, which can decrease the security risk.</p>","PeriodicalId":21472,"journal":{"name":"Risk Analysis","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144080068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence from the heterogeneity of resource-based cities.","authors":"Shufei Huang, Jianping Ge","doi":"10.1111/risa.70046","DOIUrl":"https://doi.org/10.1111/risa.70046","url":null,"abstract":"<p><p>Environmental risks have gained significant attention in recent years, especially in resource-based cities, which are often more vulnerable due to their reliance on resource-intensive industries. Most existing studies focus on the direct emission reduction effect of environmental regulation, but fail to systematically reveal its dynamic regulatory mechanism on the multidimensional environmental risks of resource-based cities. Based on the Driving forces-Pressure-State-Impact-Response framework and the characteristics of resource cities, we construct a multidimensional assessment system. Taking typical resource cities in China from 2012 to 2021 as the research object, based on the results of environmental risk assessment, we systematically analyze the differentiated effectiveness of environmental regulation from the perspectives of development stage and resource endowment. It is found that: (1) environmental risks of different types of resource-based cities show significant heterogeneity in cumulative characteristics, and their intensity is synergistically regulated by clean technology, ecological restoration, and policy response; (2) the effectiveness of formal regulation to environmental risk shows an inverted U-shape evolution with the life cycle of the resource-based city, and the inhibitory effect of the declining resource-based cities reaches the peak; and (3) resource endowment regulates the effectiveness of environmental regulation, and the pollution-exposed type of fossil energy resource-based cities rely on formal regulation, while ecologically sensitive forest cities rely on the incentive of informal regulation.
