Policy &Internet, Volume 16, Issue 4, Page 818-832, December 2024.Abstract In recent years, the pace of Internet regulation around the world has quickened, with states increasingly confident that they can and should hold major platform companies to account. New laws have been developed to address the risks of digital technologies and law‐makers have drawn on familiar regulatory principles and legacy frameworks in ...

Policy &Internet, Volume 16, Issue 3, Page 643-660, September 2024.Abstract Despite an unprecedented abundance of news content, both news avoidance and dissatisfaction are rising. Blending journalism, philosophy and law scholarship, this paper argues that ‘news choice overload’ causes paralysis and poor outcomes as it transfers power to algorithms, thereby harming autonomy and, in turn, democracy.

Change in cyclone disaster vulnerability and response in coastal Bangladesh
Disasters, Volume 48, Issue 2, April 2024.The number of deaths owing to tropical cyclones in Bangladesh has significantly reduced. Category 4 Cyclone Gorky in 1991 and Sidr in 2007 caused 147,000 and 4,500 deaths respectively, whereas Category 1 Cyclone Mora in 2017 resulted in six. Face‐to‐face interviews with 362 residents, participant observation, and focus‐group discussions answer a ...

Zhejiang Daxue xuebao. Lixue ban, 2016 利用TRMM（热带测雨雷达）搭载的TMI（微波成像仪）反演廓线资料，分析“菲特”台风登陆前、后云团内部水凝物的分布种类，依此选择WRF区域中尺度模式下符合条件的6个云微物理过程参数化方案（Lin，WSM6，Godgce, WDM6, Morrison以及Thompson方案），模拟2013年10月6〜8日的台风过程.从降水落区、强度，水凝物及风场垂直分布，台风路径及强度等方面对预报性能进行对比，结果表明，选用的6个云微物理方案都较好地模拟了浙江暴雨的范围和强度.结合Ts评分，降水量级越大 ...

Dianci bileiqi, 2016 近海海底一般地形复杂,为了抗台风和抗海底冲刷的需要,海上风力发电机组的基础会使用高桩承台基础结构。高桩承台结构在高水位时,顶部水泥平台部分浸没水中,会影响入地电流流散,有必要对利用高桩承台基础作为自然接地体的可行性进行研究。建立了以高桩承台基础作为海上风电机组的自然接地体的仿真模型。利用将导体分段,求解各微段导体的格林函数,再叠加的方法求解出模型的接地电阻,在此基础上,利用指数函数模型拟合,得出接地电阻与水位变化的关系曲线。计算结果表明,海上风电机组利用高桩承台结构作为自然接地体能够满足实际工程的需要 ...

Zhejiang Daxue xuebao. Lixue ban, 2015 利用NCEP、fnl再分析资料和常规探测资料分析1981~2010年台州市局地暴雨的时空分布，并进行天气分型，对平均形势和典型个例进行了对比分析.结果表明：(1)台州局地暴雨日约占总暴雨日数的1/3，月际变化显著；局地暴雨总体上呈北多南少分布；(2)5~6月暴雨主要由西风带类造成，8~9月主要由东风带造成，7月各类暴雨均有发生.热带系统、移动低槽、南海台风是引发台州局地暴雨最多的系统.局地暴雨对于水汽输送和动力条件的要求比大暴雨要低得多.各型范围暴雨和局地暴雨在850 hPa形势场上有较明显的差异；(3)
