Risks of Time and Chronology as an Underpinning Infrastructure for Critical Systems: Emerging Chronorisks and Chronosecurity Needs

open access: yesJournal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.
ABSTRACT Time and chronology form the invisible architecture upon which modern civilization depends, governing synchronization across markets, power grids, communication networks, transportation, and defense. Yet, this shared temporal framework, engineered through atomic clocks, satellites, and digital synchronization, faces growing vulnerabilities ...

应用于海上风电接入的VSC-HVDC系统主网侧交流故障穿越方案 [PDF]

open access: yes全球能源互联网, 2019
海上风电是可再生能源的重要形式和组成部分,通过基于电压源换流器的高压直流输电(VSC-HVDC)技术进行风电的远距离接入,使远离海岸的区域建设风电场成为可能,另外该技术也具备更大规模风场的接入能力。目前世界范围已有多个应用VSC-HVDC输电系统将海上风电场接入到陆上主电网的工程规划。然而,大规模风电会对系统的稳定性带来诸多挑战,尤其需要确保在故障工况下风电场及主电网的稳定性,VSC-HVDC以其优良的灵活性成为应对此类挑战的不二选择。本文对不同风电接入方式下系统的故障穿越方案进行了总结,对VSC ...

Managing Risk, Reinforcing Environmental Racism: The Biopolitics of Pesticide Regulation in California Agriculture

open access: yesReview of Policy Research, Volume 42, Issue 6, Page 1509-1524, November 2025.
ABSTRACT This paper provides a retrospective on California's oversight of 1,3‐dichloropropene (1,3‐D). It utilizes archival documents, including internal memos, emails, and risk assessments, to demonstrate how the state's Department of Pesticide Regulation consistently expanded allowable 1,3‐D use while presenting each policy change as scientifically ...

Exploration for effects of acoustic stimulus on movement behavior and HSP70 expression of two kinds of marine crustaceans [PDF]

open access: yes, 2016
水下噪声会潜在的引起海洋生物紧张,分散和掩蔽这些海洋生物重要的声信号,进而对海洋生物的行为和生存造成影响。近几十年来,随着人类社会的不断发展,人们将发展目光投向了占有全球71%面积的海洋。伴随海洋事业的快速发展,海洋工程噪声对海洋生物的影响引起了人们的极大关注。虽然目前已有不少研究成果评估了水下工程噪声对海洋生物的影响,这些噪声包括轮船、打桩、地震勘探以及风电场等水下噪声,表明海洋工程等人为噪声对鱼类以及海洋哺乳动物都将造成了不同程度的影响和伤害。但是 ...

Environmental disasters and ecomodernist beliefs: Insights from a quasi‐natural experiment

open access: yesPolicy Studies Journal, Volume 53, Issue 1, Page 201-231, February 2025.
Abstract This article contributes to knowledge of how environmental disasters affect ecomodernist beliefs, i.e. the view that technology can solve environmental problems. Such beliefs in the general public are key to build mass support for environmental policies relying on large‐scale scientific solutions, but their stability is poorly understood.
