CAREER: Risk-Sharing Communication Networks for Compound Disasters.

社区共享不同的灾害风险信息，可能导致生存资源分配不均，谁应该负责的混乱，以及未能建立信任的沟通。了解社区中的人们是如何联系在一起的，可以揭示谁无法获得资源，谁扮演着关键角色，以及有关风险和资源的信息在灾难期间如何传播。该项目引入了一个新的概念，即风险分担公地，以解决灾害研究中的这些沟通问题，并提供恢复能力的补充途径。该项目结合定性和定量方法，纳入新的和未被充分研究的风险分担决策因素，得出并验证了对灾害时期风险沟通的公有框架的基本理解。该项目提供灾害风险管理方面的教育和培训活动，并让利益攸关方和社区志愿者参与，以便在灾害造成的混乱环境中更好地进行自我组织和决策。从这个项目中获得的可操作的知识适用于不同的灾害形式和组合，为政策提供信息，以提高灾害多发社区的准备、响应和恢复工作的有效性。这个学院早期职业发展(CALE)项目调查风险分担公地，探索当面临灾难时，人们和社区如何驾驭收集和共享关键信息和资源的内在复杂性。该项目(A)确定灾害风险沟通中当地社交媒体网络和社交媒体网络之间的关系；(B)确定人们如何使用多样化的信息源，以及社交网络如何在灾害事件发生前后对风险分担决策作出权衡；(C)进行归纳的人种学研究，随后进行家庭网络调查和决策实验，以便将风险分担决策的新因素纳入量化数据和建模计划，以便能够根据规模和地点作出有效的推断；(D)利用先进的网络科学和数据驱动的方法，捕捉网络构成的变异性以及风险沟通中信任形成和信息级联的时空动态。该项目的综合研究、教育和社区参与框架的结果可以为灾害管理政策干预的决策者提供信息，以共同即兴制定和确定恢复能力的途径。该项目由人类-环境和地理科学(HEGS)、人类网络和数据科学(HNDS)以及已建立的激励竞争研究计划(EPSCoR)联合资助。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Communities share information about disaster risks differently, likely resulting in uneven distributions of survival resources, confusion over who is responsible, and communication that fails to foster trust. Understanding how people are connected in a community can reveal who lacks access to resources, who plays a key role, and how information about risks and resources can spread during disasters. This project introduces a new concept, the Risk-Sharing Commons, to address these communication issues in disaster research and provide complementary pathways to resilience. Combining qualitative and quantitative methods to incorporate new and understudied factors of risk-sharing decisions, this project derives and validates a fundamental understanding of the Commons framework for risk communication in times of disasters. The project offers educational and training activities in disaster risk management and engages stakeholders and community volunteers for better self-organization and decision-making in disaster-induced chaotic environments. The actionable knowledge derived from this project applies to different forms and combinations of disasters, informing policies to enhance the effectiveness of preparedness, response, and recovery efforts in disaster-prone communities.This Faculty Early Career Development (CAREER) project investigates the Risk-Sharing Commons, exploring how people and communities when facing disasters, navigate the inherent complexities of gathering and sharing critical information and resources. This project (a) establishes the relationships between local social and social media networks in disaster risk communication; (b) identifies how people use a diverse set of information sources and how social networks weigh into risk-sharing decisions before and following disaster events; (c) conducts inductive ethnographic research followed by a household network survey and decision-making experiments to incorporate new factors of risk-sharing decisions into a quantitative data and modeling plan that can make inferences validated in terms of scale and place; and (d) captures the variability in network composition and the spatiotemporal dynamics of trust formation and information cascades in risk communication using advanced network science and data-driven methods. Findings from the integrated research, education, and community engagement framework of this project can inform decision-makers on disaster management policy interventions to collectively improvise and identify pathways to resilience.This project is jointly funded by Human-Environment and Geographic Sciences (HEGS), Human Networks and Data Science (HNDS), and the Established Program to Stimulate Competitive Research (EPSCoR).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
