Critical Infrastructure, Climate Disasters, and Cultural Survival: Policy Failures and Community Displacement in the Era of Managed Retreat

open access: yesJournal of Critical Infrastructure Policy, Volume 7, Issue 2, Fall/Winter 2026.
ABSTRACT Climate disasters are currently changing territory around the world by showing large inequalities that exist in infrastructure systems, governance arrangements, and development pathways. In many cases, climate risk response strategies like managed retreat have been framed as practical approaches to respond to increasing climate disasters ...

Mind the gap, exploring the expectation gap in political leadership in disasters: An Australian case study 注意差距——探究灾害中政治领导力的期望差距:澳大利亚案例研究 Cuidado con la brecha, exploración de la brecha de expectativas en el liderazgo político en desastres: Un estudio de caso australiano

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 16, Issue 1, March 2025.
Abstract This article uses expectation gap theory to explore news coverage of the leadership performance of a national political leader in a major bushfire disaster in Australia. It does so to identify the types of behaviors and leadership that leader enacted and embodied during these events and what fire‐affected communities expected that politician ...

The tensions of crowdsourcing disaster response in disaster‐specific Facebook groups after the Camp Fire 营地火灾后灾害专用脸书群组中出现的众包复原力组织紧张关系 Las tensiones de la resiliencia del crowdsourcing en grupos de facebook específicos para desastres después del incendio del campamento

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 15, Issue 2, Page 261-283, June 2024.
Abstract Disaster‐specific Facebook groups (DSFGs) are Facebook groups devoted to a specific disaster or set of disasters. I argue DSFGs offer opportunities for disaster response and resilience organizing that can mitigate the limitations of institutionalized disaster response and illustrate the benefits and detriments of the use of DSFGs by survivors ...

森林火灾流域侵蚀泥沙来源指纹技术研究进展

open access: yesShuitu Baochi Xuebao, 2023
指纹识别技术是量化流域侵蚀泥沙来源的有效手段,如何应用于火烧流域,仍有一些问题值得探讨。通过回顾相关文献,总结森林火灾通过植被、土壤和灰烬加剧土壤侵蚀的机制,介绍应用指纹技术研究火烧流域泥沙来源的案例,重点分析放射性核素、矿物磁性、物理性质、地球化学元素和有机组分等指纹因子在火烧迹地的含量和性质变化,论述各类指纹因子在火烧流域泥沙来源研究中的适用性,并提出未来应重点关注指纹技术的物理基础、火灾后土壤性质的时空变化规律、指纹因子稳定性验证、燃烧灰烬的影响以及大粒径泥沙的识别等问题 ...

Experimentally testing animal responses to prescribed fire size and severity

open access: yesConservation Biology, Volume 38, Issue 3, June 2024.
Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,

Theorizing reactive policy entrepreneurship: A case study of Swedish local emergency management

open access: yesPolicy Studies Journal, Volume 52, Issue 1, Page 73-89, February 2024.
Abstract In this article, we examine public policy change at the local level of governance in the aftermath of an extraordinary event. Using the case study of a Swedish municipality after the sweeping forest fire of 2014, we contend that policy entrepreneurship, like its market counterpart, may under certain conditions take on a wider range of ...

整合“心理-社会-文化”的灾后心理援助

open access: yes, 2011
我国真正的灾后心理援助,起始于2008年汶川大地震。当时参与灾后心理援助的主力队伍,基本上是习惯在诊室里进行心理咨询与心理治疗的"心理医生"。这些专家,往往是在求助者预约-挂号-缴费以后 ...

古火灾历史重建的研究进展

open access: yes, 2011
火是地球系统的重要组成部分,与气候、植被、生物地球化学循环和人类活动密切相关。火对全球气候和生态系统的影响已成为目前全球变化研究的一个热点。火灾发生后会在周围的环境中留下许多燃烧产物,如黑碳、木炭屑、多环芳烃、左旋葡萄糖等,它们广泛存在于海洋、湖泊、河流、土壤和陆地风成沉积物中;还会留下一些火灾痕迹,如树木火疤、土壤磁学参数的改变。通过这些记录不仅可以反映火活动的历史,同时能够反映历史时期的气候条件及植被格局,为火灾历史重建提供宝贵的信息资料 ...

高压电缆接头防火隔爆措施的有效性研究

open access: yesGaoya dianqi, 2023
为降低高压电缆故障引发的通道火灾、地铁停运、重要用户停电等影响,电力部门在电缆接头处大量安装了防火毯、防爆毯、防火槽盒等防护装置,但防护效果甚微。文中在分析高压电缆接头防火隔爆现状的基础上,以220 kV电缆接头为样本,测试了接头内主要材料的燃烧温度,并对目前常用的防火毯、防火板、防爆隔板进行了耐火性能的检测。文中通过电缆接头短路故障模拟试验校核了常用防火防爆措施的有效性,结果表明,目前常用的电缆接头防火措施均难以防范试验条件下的短路冲击和持续燃烧,现状高压电缆通道仍存在火灾和电缆群伤风险 ...

梁柱全焊节点高温后抗震性能试验研究

open access: yesJianzhu Gangjiegou Jinzhan, 2017
梁柱全焊节点在建筑钢结构中广泛应用,其火灾后受力性能对整个结构灾后承载安全至关重要。通过5个梁柱全焊节点试件高温冷却后的低周反复加载试验,研究了高温过火对其承载力、延性和耗能能力的影响规律。试验过火温度介于500800℃之间,冷却方式为自然冷却。试验结果表明,所有试件均发生梁柱翼缘对接焊缝处的断裂破坏。高温冷却后试件的抗弯承载力较未过火试件有所降低,延性和耗能能力有所提升,变化幅度统一呈现随过火温度的升高先增大后减小的变化规律。当过火温度为700℃时,节点承载力降低最大,降低幅度约为20 ...
