China’s censorship infrastructure is widely recognized as sophisticated, strict, and comprehensive. We conducted a qualitative study to understand Chinese citizens’ practices to navigate the censored Chinese Internet. We found that participants’ practices were closely related to their understanding of and resistance to the censorship infrastructure. Participants switched between public and priv...

While it is widely celebrated for its emancipatory potential, many governments view the Internet with alarm and have attempted to limit access or to control its contents. This project seeks to provide a comprehensive, theoretically informed analysis of the geogr...

Objective: This paper aims to introduce a modified kernel-type ridge estimator for partially linear models under randomly-right censored data. Such models include two main issues that need to be solved: multi-collinearity and censorship. To address these issues, we improved the kernel estimator based on synthetic data transformation and kNN imputation techniques. The key idea of this paper is t...

The Internet censorship conflict is like a game of cat-and-mouse, in which the censor discovers and acts on distinguishers that set the usage of censorship resistance systems (CRSs) apart from other Internet usage, and the CRSs’ attempts to remove and mitigate these distinguishers. Our systematization is based on a simple and intuitive model of the distinguisher-leveraging censorship apparatus,...
