Policy Studies Journal, Volume 51, Issue 4, Page 817-842, November 2023., 2023 Abstract Are narratives as influential in gaining the attention of policymakers as expert information, including for complex, technical policy domains such as artificial intelligence (AI) policy? This pre‐registered study uses a field experiment to evaluate legislator responsiveness to policy entrepreneur outreach.

Conservation Biology, Volume 36, Issue 4, August 2022., 2022 Abstract As ecological data and associated analyses become more widely available, synthesizing results for effective communication with stakeholders is essential. In the case of wildlife corridors, managers in human‐dominated landscapes need to identify both the locations of corridors and multiple stakeholders for effective oversight.

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 ...

基于改进的Wait算法考虑跨越混合路径区域的城市配网线路雷电过电压研究
Dianci bileiqi, 2020 配电网具有运行环境复杂、分布广、绝缘水平相对较低的特点,极易发生雷害事故。基于Wait算法并对其进行改进,研究跨越水域-陆地-水域多路径区域情况下,雷电辐射场变化趋势,同时针对混合路径情况,设置多种参数方案研究其对配网线路耦合雷电过电压的影响。研究表明:三段区域混合路径情况下,从低电导率到高电导率的变化时,降低了水平电场分量,同时提高了垂直电场分量,中间陆地区域的增大对配电线路近端感应的雷电过电压峰值无影响,而减小了远端雷电过电压峰值。同时水平电场分量从高电阻率土壤行进到低电阻率土壤时 ...

Gaoya dianqi, 2023 交流电场下超疏水涂层表面液滴的滑动和凝并特性对其污闪特性具有重要影响，为了表征超疏水涂层表面液滴的运动特性，以环氧树脂板为基底利用喷涂法制备了超疏水涂层，测量了均匀电场下超疏水涂层表面不同体积液滴的临界运动场强，并利用基于图像的目标跟踪方法绘制了不同体积液滴的运动轨迹；最后通过仿真计算和理论推导，分析了交流电场下液滴运动机理以及体积对液滴临界运动场强和运动速度的影响。结果表明：液滴体积对其临界运动场强的表现出明显的“体积效应”，0～100μL液滴的临界运动场强在体积为40μL出现一极小值 ...

Dianci bileiqi, 2016 由雷电引起的浪涌电压和电流是造成电子设备失效甚至损坏的主要因素。雷电辐射电磁场的水平电场分量在雷电瞬态过电压的研究计算中占据重要位置,然而目前针对雷电辐射水平电场的近似算法均是将地表假设成光滑地表,但现实中的地表常常存在高低起伏的特征。针对上述问题,基于Cooray-Rubinstein算法（简称C-R算法）提出了一种适用于二维分形粗糙地表的雷电水平场计算的新算法,并利用三维时域有限差分方法对其适用范围和精度进行了检验。结果表明:相比于光滑地表,粗糙地表对雷电水平电场的衰减不容忽视 ...
