Patchwork Governance on KidTok: Balancing Regulation and Community Norms
ABSTRACT TikTok's rapid growth among young users has introduced unique challenges to existing frameworks for understanding child internet fame. We identify “KidTok” as a unique networked public for “internet famous” young people on TikTok shaped by the platform's sociotechnical environment and explore the novel risks that governance should address ...

大量风机控制和电力变换设备集中布置于风机塔筒底部,易遭受雷电反击过电压而损坏。建立了考虑风机钢筋混凝土基础自然接地作用的雷击瞬态模型,采用频域矩量法进行求解,通过傅里叶反变换获得设备安装位置的时域瞬态过电压波形和冲击阻抗。计算结果表明,考虑混凝土中的钢筋能显著降低风机雷电冲击接地电阻和塔筒底部电位抬升,在高土壤电阻地区影响更加明显;风机承台中的钢筋散流作用明显,考虑承台钢筋时风机冲击接地电阻和塔筒底部电位升明显减小,随着垂直桩基数量的增加,风机冲击接地电阻值和塔筒电位升进一步降低 ...

Trends of drought and flood in Zhejiang Province respond to climatic warming(浙江省汛期旱涝趋势对气候变暖的响应)
近50多年来浙江省气候变化总趋势在逐渐变暖,80年代中期开始变暖明显,增幅加大.浙江省汛期各月降水量对气候变暖的响应不同:在季节转换月份5月和9月,降水量明显减小,而在夏季的降水量增加,8月尤甚.在气候变暖期,浙江省汛期旱涝事件的发生频数增加.大气环流对气候变暖的响应是:5月份,高层南亚高压偏弱偏南,中国东南部上空为平直的西风气流,引导冷空气多偏北东移,中层印缅槽的减弱导致向江南水汽输送减少,低层偏南气流远离华东,浙江省主要受单一西北干燥气流影响,降水显著偏少;8月份,青藏高压位置偏西 ...

Uncovering Xi Jinping's Policy Agenda: Text As Data Approach
How many agendas has Xi Jinping put forth and promoted since taking office in 2012, and what are the types of agendas? How much of political attention has each agenda received, and how has the allocation of attention changed over time? We utilize a dataset of presidential statements, speeches, and reports from 2012 to 2022 and employed automated text ...

Analysis on the moving track and intensity of severe typhoon "Fitow"(强台风“菲特”的移动路径及强度分析)
对强台风“菲特”进行高低层形势场分析,对其移动路径的预报和台风强度问题进行了初步探讨.分析发现,“菲特”主要受中低层引导气流的影响.利用日本静止卫星MTSAT的反演产品分析了“菲特”的强度变化情况,得到“菲特”在登陆后垂直风切变在10~15 m • s-1,不利于其强度的维持或发展.

台风灾害是导致沿海区域输配电线路故障的主要原因之一,灾前预警是抗台减灾的重要环节。目前,国内外采用的输配电线路抵御强台风预警方法一般仅考虑了台风路径和风圈范围,缺乏对台风灾害链的系统性描述,导致预警的针对性和有效性明显不足。为此,有必要深入开展沿海区域输配电线路抵御强台风预警技术的研究。首先基于输配电线路台风灾害链构建了预警体系;然后从因果、统计和混合预警3个方向综述了输配电线路抵御强台风预警方法的研究进展,并评述了各种方法的优缺点;最后提出了一种基于网格化 ...

An objective forecast technique for post-landfall track of tropical cyclones(热带气旋登陆后路径的客观预测方案)
提出一个东海热带气旋登陆后路径的客观预报方案.方案应用热带气旋初始参数和数值预报产品,构造登陆时刻和未来时刻环境要素场的多元客观相似判据.通过定义非线性的相似指数综合评估历史热带气旋样本与预报热带气旋在多元判据下的连续动态相似程度,以此找到相似样本.应用相似样本的历史路径进行坐标变换和相似指数的权重综合,得到热带气旋登陆后预报路径.预报试验表明该方案具有预报技巧.

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 ...

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.
