Review of Policy Research, Volume 40, Issue 5, Page 626-645, September 2023., 2023 Abstract In their efforts to digitize public service delivery, countries increasingly use algorithms based on mathematical models, data and/or a combination of different administrative datasets to issue decisions, but recent studies point towards challenges around citizens' understanding, accessing, and filing objections to such automated decisions ...

Journal of Traumatic Stress, Volume 36, Issue 1, Page 129-143, February 2023., 2023 Abstract During the Great East Japan Earthquake, many people experienced the loss of family and friends, among other traumatic events. This study sought to clarify the impact of the loss of significant close others on posttraumatic stress symptoms (PTSS), as well as the factors associated with PTSS, among individuals who experienced the loss of ...

Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.ABSTRACT Bangladesh's goal of achieving high‐income status by 2041 requires dependable, low‐emission, and affordable energy. With near‐universal grid coverage and increasing demand, nuclear energy is a strategic asset for long‐term baseload supply. However, the existing financing model, typified by the country's most expensive $12.65 billion Rooppur ...

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

Dianci bileiqi, 2013 变电站的雷电侵入波过电压与线路绝缘子串的闪络情况密切相关,文中基于ATP-EMTP,建立了500 kV变电站和进线段的雷电计算模型,研究了绝缘子串闪络判据对变电站雷电侵入波过电压的影响,校验了采用更符合线路实际运行情况的先导闪络判据时变电站的绝缘配合情况。研究结果表明:绕击情况下,绝缘子串采用先导闪络判据时变电站设备上的雷电过电压增大。其中距变电站1.5 km内,可能会对变电站设备产生威胁;而距离变电站1.5 km后,由于雷电波在传播过程的衰减和畸变,侵入波对变电站设备不构成威胁。为保证变电站的安全运行,

Dianci bileiqi, 2016 主要针对江西省某铜矿开采公司变电站雷害事故研究与分析,根据其变电站短路电流的大小发现其变电站接地网的接地电阻过大,变电站主变变压器低压侧线路避雷器单独接地以及变电站内部部分使用组合式过电压保护器等防雷缺陷及问题。提出在变电站外铺设辅助环形接地网、避雷器引接到变电站主接地网上以及更换组合式过电压保护器等改造措施,最后通过电磁暂态软件ATP-EMTP仿真软件对避雷器引接到变电站主接地网前后对于变压器低压侧线路过电压进行仿真验证,验证改造措施的有效性,同时此种防雷改造措施同样可以引用于其他矿区的变电站。
