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

Dianci bileiqi, 2019 通过深度分析中性点经小电阻接地方式所存在的问题,提出了一种配电网中性点经智能电阻接地方式。与小电阻接地方式相比,智能电阻采用分区法,根据中性点电压大小将故障类型分为高阻、中阻以及低阻3个区域。在低阻故障时,能够快速选线跳闸;在中阻故障时,经过延时判断,避免对瞬时性故障的误判;在高阻故障时,启动中、低电阻动态切换,进行准确选线。综合理论分析和仿真计算可得:智能电阻接地方式不仅拥有小电阻接地方式的优点,还能够解决小电阻接地方式中部分供电可靠性低、单相低阻接地时故障点电流过大及单相断线（高阻）接地时零序保护 ...

Beyond Motivation: Modeling the Predictive Role of L2 Pride in Informal Digital Learning of English
International Journal of Applied Linguistics, Volume 35, Issue 4, Page 1938-1952, November 2025.ABSTRACT This study investigates the role of second language (L2) pride—an understudied affective factor—in shaping learners’ language learning motivation and involvement with informal digital learning of English (IDLE). Drawing on questionnaire data from 1388 Chinese university EFL students, the study employs structural equation modeling to examine ...

基于故障性质判断法的配电网中性点动态接地成套装置的开发及应用
Dianci bileiqi, 2019 通过对配电网中性点经消弧线圈接地方式,以及小电阻接地方式的特点分析及存在的问题进行了更加深入地研究,并开发研制出了配电网中性点动态接地成套装置。该装置具备消弧线圈接地与小电阻接地方式二者的优点,又能够灵活地解决两者存在的缺点。其功能在于配电网发生单相接地故障时,依据故障特征量和参数,就可以对故障的性质进行智能判断。满足在瞬时性接地故障时,故障点的绝缘水平能够快速恢复,提高了电网供电可靠性;同时在永久性单相接地故障时,能够快速且准确地选出,并切除故障线路,确保了设备和人身安全。经大量实验及运行结果证明 ...
