How does a focusing event shape public opinion? Natural experimental evidence from the Orlando mass shooting

open access: yesPolicy Studies Journal, Volume 53, Issue 2, Page 463-479, May 2025.
Abstract Policy process theories posit that focusing events can trigger significant shifts in public attention and policy preferences, thereby reshaping public agenda setting. Prior studies, however, have not clearly defined the scope of public opinion changes induced by these focusing events, leading to inconsistent empirical findings. This study aims

Social protection and resilience in protracted crises

open access: yesInternational Social Security Review, Volume 78, Issue 2-3, Page 173-190, April-September 2025.
Abstract This article critically examines perspectives on social protection’s role in strengthening resilience capacities in protracted crises – contexts where conflict and displacement persist for five years or longer. These crises shape how stakeholders navigate their mandates to provide support, while influencing how affected communities seek to ...

“Security, first of all, begins at home”: How Finland, Latvia, and Germany prepare “ordinary people” for crises

open access: yesEuropean Policy Analysis, Volume 11, Issue 1, Page 114-137, Winter 2025.
Abstract In Europe, and specifically in countries bordering the Baltic Sea, preparedness issues have moved up the policy agenda since Russia's 2014 and 2022 invasions of Ukraine. “Ordinary people” are encouraged to prepare for crises—be it through stockpiling food at home, fact‐checking information, or signing up for military training.

The false promise of individual digital sovereignty in Europe: Comparing artificial intelligence and data regulations in China and the European Union

open access: yesPolicy &Internet, Volume 16, Issue 4, Page 711-726, December 2024.
Abstract In the digital sovereignty debate, countries and blocks seek to build technological and regulatory capacity to ascertain technological autonomy—definitions notwithstanding. Meanwhile, these actors seek to position themselves discursively, differentiating their own understanding of digital sovereignty from that of competing powers.

Financial speculation meets cultural heritage in China's wildlife markets

open access: yesConservation Biology, Volume 38, Issue 5, October 2024.
Abstract Environmental regulations restricting the use of a natural resource or species often have unintended consequences. One example is prohibitions on the international trade in culturally important endangered wildlife. Trade restrictions may artificially increase scarcity and, consequently, value.

Quantifying species biases among multidata sources on illegal wildlife trade and its implications for conservation

open access: yesConservation Biology, Volume 38, Issue 5, October 2024.
Abstract Unsustainable wildlife consumption and illegal wildlife trade (IWT) threaten biodiversity worldwide. Although publicly accessible data sets are increasingly used to generate insights into IWT, little is known about their potential bias. We compared three typical and temporally corresponding data sets (4204 court verdicts, 926 seizure news ...

220kV输电线路反击耐雷性能及高电位转移现象的研究

open access: yesDianci bileiqi, 2015
采用ATP/EMTP软件对猇亭地区220 k V输电线路建模,通过软件仿真,分析了避雷器安装方式及工频相位角对线路反击耐雷性能的影响。利用两者对线路反击耐雷性能的影响,提出了两种新方案,并针对雷击杆塔这种情况,仿真分析了原方案及两种新方案的反击耐雷性能及高电位转移后对相邻杆塔的影响。结果表明:方案二的反击耐雷性能好,而且高电位转移现象轻微,不威胁相邻杆塔的安全运行。

Endangered beach mouse resistance to a Category 5 hurricane is mediated by elevation and dune habitat 濒危海滩鼠类五级飓风的抵抗力受海拔和沙丘栖息地的调节

open access: yesIntegrative Conservation, Volume 3, Issue 1, Page 36-45, March 2024.
Threatened and endangered species that occur in coastal areas are susceptible to the impacts of hurricanes that can destroy and reorganize their habitats. We used long‐term tracking of endangered beach mice to reveal they survive these impacts by using high elevation dune habitats to stay safe.

线路避雷器安装布点策略研究

open access: yesDianci bileiqi, 2019
雷击是引起输电线路跳闸的主要原因之一。加装线路避雷器是根治输电线路雷击跳闸的有效手段。以福建电网220kV卓旧I路为例,建立了反击计算模型,对比了不同避雷器安装方式对典型杆塔及其相邻杆塔反击耐雷水平和反击跳闸率的影响,得到了线路避雷器的保护作用范围,并据此提出了避雷器安装布点策略:优先考虑连续多基杆塔反击跳闸率为C级或D级的情况,结合线路档距制定不同的安装方案;对于杆塔反击跳闸率为C级和D级,相邻杆塔未达到C级或D级的情况,C级杆塔安装一相避雷器,D级杆塔安装两相避雷器。基于提出的避雷器安装布点策略 ...

Complicated grief and posttraumatic stress after loss and separation under terror conditions

open access: yesJournal of Traumatic Stress, Volume 37, Issue 1, Page 154-165, February 2024.
Abstract The lives of people in conflict areas are often characterized by the experience of traumatic events frequently accompanied by loss and separation. These can equally trigger symptoms of posttraumatic stress disorder (PTSD) and complicated grief (CG).
