Confronting policy myopia: Short‐term government policy and information seeking behaviors in rural Thailand

open access: yesReview of Policy Research, Volume 43, Issue 1, January 2026.
Abstract Short‐term policy (STP) has attracted considerable attention as a form of time‐related public policy and is typically used to solve urgent problems. The objective of this study, which considers STP as policy myopia from an information science perspective, is to discuss the challenges encountered during the STP policymaking process and their ...

不同接地方式下变压器35 kV绕组外部过电压特性分析及防治措施

open access: yesDianci bileiqi, 2023
变压器35 kV绕组中性点接地方式较多,现有设计没有对不同接地方式下变压器的防雷措施进行专门考虑,导致变压器35 kV侧雷击事故频发。为了对不同接地方式下变压器35 kV绕组雷电侵入波特性及防治措施进行研究,采用电磁暂态分析软件ATP-EMTP建立仿真模型,对35 kV绕组星形接线的配网变压器和三角形接线的风电场升压变进行了雷电侵入波电磁暂态仿真,分析了导致35 kV绕组绝缘损坏的雷电侵入波特点,考察了不同安装方式下避雷器对雷电侵入波防治的有效性。研究表明不同接地方式下变压器35 ...

Continuities in policy change: The case of squatter housing redevelopment strategies in Türkiye

open access: yesReview of Policy Research, Volume 43, Issue 1, January 2026.
Abstract The introduction of the neoliberal agenda in the 1980s marked a milestone for urban studies, where the neoliberal framework became widely accepted as both given and explanatory for understanding urban phenomena. This tendency often obscured policy continuities rooted in the historical and social contexts of specific geographies.

Evidence‐Based Policymaking and Spatial Planning. Factors of Evidence Utilization

open access: yesReview of Policy Research, Volume 43, Issue 1, January 2026.
ABSTRACT This paper investigates the role and usability of expert‐generated evidence in democratic policymaking, with spatial planning as a case study. Drawing on the literature on evidence‐based policymaking in political science and planning, and employing the CRELE and ACTA frameworks with a critical realist approach, the study analyses the ...

中性点采用两种接地方式的配电网单相接地故障的比较

open access: yesGaoya dianqi, 2008
为了更好地应用小电阻接地方式来提高配电网系统的安全性、可靠性,笔者研究了中性点采用小电阻接地和消弧线圈接地的配电网在发生单相接地故障时的不同特点以及保护方式的差异。首先采用对称分量法对这两种配电网的单相接地故障进行分析,并采用MATLAB进行了仿真。研究结果表明,采用这两种接地方式的配电网在发生单相接地故障时的不同特点导致其继电保护措施也各不相同。因此,随着中性点经小电阻接地的接地方式的推广,其相应的单相接地故障继电保护措施需进一步完善。
