Review 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 ...

Gaoya dianqi, 2021 电缆的传播常数、特征阻抗、相速度的高频特性表征了电缆的高频传输特性,而准确获取电缆的高频传输特性是电缆故障定位的基础。文中针对现有测试技术的不足,提出了基于电缆阻抗谱的同轴电力电缆高频传输特性获取方法,研究结果表明:在300 kHz～100 MHz频率范围,随着频率的增大,衰减常数和相移系数近似线性增大;相速度随频率的增大略有增加,并趋于稳定值;受测量接线处附加电感和附加电容的影响,特征阻抗的高频特性出现较为严重的畸变。

Gaoya dianqi, 2018 超声波法是一种非破坏性的电力设备局部放电检测方法,运用数值计算方法可以有效地分析超声波的声场特性。为明确特高压GIS局部放电超声波信号的传播特性,采用有限元计算方法仿真研究了特高压GIS不同位置发生局部放电时超声波信号的传播特性。按照某1 100 k V特高压GIS实际尺寸,建立了特高压GIS三维仿真模型,设置单极子声源分别位于GIS中心导体和盆式绝缘子处,布置多个超声波传感器位于GIS外壳不同位置用于接收局部放电产生的超声波信号。仿真得到了GIS壁面上接收的来自不同位置单极子声源产生的超声波声压分布图,

Clip Voice: Misogyny and the Renegotiation of a Gendered Vocal Style in Chinese Digital Discourse
Journal of Sociolinguistics, Volume 29, Issue 5, Page 348-359, November 2025.ABSTRACT The participatory culture of social media allows women's voices to be heard but also parodied and policed. On Chinese social media platforms, where performers rapidly adopt and transform vocal trends for engagement, discourse on gendered vocal styles has proliferated.

Integrative Conservation, Volume 4, Issue 3, Page 354-361, September 2025.Conservation can better utilize politicized digital interventions to increase support for bold policy change. By shifting from educational approaches to politically oriented strategies, the conservation movement can build the sustained support necessary to address the biodiversity crisis.

People and Nature, Volume 7, Issue 9, Page 2228-2240, September 2025.Abstract Free‐ranging cats pose significant threats to biodiversity, yet the cat‐related media online has attracted millions of viewers. The reasons behind this surge in popularity, however, remain underexplored. To address this gap, we conducted a comparative culturomic analysis of over 6 million comments and 60,000 unique tags from over 3 million ...

Gaoya dianqi, 2016 文中在定义谐波电压传递系数的基础上,分析了谐波电压传递特性研究的基本方法;文中针对包含不同电压等级的具体算例分析了谐波电压在不同电压等级之间传播的基本规律。分析结果显示:谐波电压从高电压等级向低电压等级传播具有较强的穿透力,与下游电网线路对地电容、具体元件参数、下游电网无功补偿装置的配置等均有较大关系;谐波电压从低电压等级向高电压等级的传播较弱,低电压等级无功补偿装置的投运与否对向高电压等级传播特性的影响不大;同电压等级谐波电压的传播与其相互距离有关,距离越远,传递效应越弱。

Exploring Social Media Purposes and Strategic Approaches Among US Municipalities
Policy &Internet, Volume 17, Issue 3, September 2025.ABSTRACT Social media represents a strategic tool for governments to disseminate information, build relationships, and achieve outcomes consistent with stated political, social, and administrative missions. As a digital ecosystem, social media is an essential part of any modern communication strategy, though there is little research into the purposes ...
