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 ...

ABSTRACT Deep fakes can be used for political advertising, enabling politicians to change their characteristic features or minimize deficits of their performances. Such a strategy may meet with great interest, which in some circumstances increases participation and might influence deliberation. It was applied in South Korea, and its variations appeared

Complete convergence for ρ--mixing random fields(ρ--混合随机场的完全收敛性)
讨论了ρ--混合随机场的部分和完全收敛性.在一些适当的条件下,获得了较为一般的ρ--混合随机场的部分和完全收敛性定理,并得到了完全收敛速度与矩条件之间的等价关系.所得结果推广了ρ*-混合随机场和负相伴序列的相应结果.且将Hsu-Robbins型定理推广到ρ--混合随机场的情形.定理的证明基于Rosenthal型最大值不等式、Rosenthal型不等式、几个引理及缓变函数的性质.

Public enterprise pricing as redistributive policy
Abstract This paper analyzes public enterprise pricing as a form of redistributive politics. Beyond regulation and public goods, governments provide goods and services on a fee‐for‐service basis. Governments recover all or part of the costs of these services through user charges.

所提出的两重包络加工方式是建立在两重包络理论基础上的,它可以实现对空间凸轮廓面的无理论误差重构。通过对两重包络法的加工过程的分析,比较了与其它非等价加工方式的不同之处。在此基础上建立了点刀位计算模型,研究了两种走刀方式并给出了各自对应的刀位序列计算程序。两重包络加工方式适应范围广,柔性强,特别适应于单件小批量生产。这种加工方式可作为等价加工方式和刀位补偿方式的有益补充,满足实际生产的需要。

变压器油中溶解气体在线监测是对油浸式变压器绝缘状况进行实时监测的有效技术手段。对油中溶解气体在线监测装置进行运行质量评价,对装置选型、供应商评价和保障变压器运行可靠性具有重要意义。现有的变电在线监测装置运行质量评价研究存在数据规模小和评价指标有限等问题。为提高评价水平,文中统计分析了大型数据集中在线监测装置的厂家分布、运行年限分布、数据质量等重要信息,然后建立了油中溶解气体在线监测装置运行质量的模糊层次综合评价模型;最后对数据集进行评价结果分析统计,证明了该评价体系反映各厂家监测装置实际应用情况的准确性。
