Lists over one hundred words and phrases that are blocked on China's most popular social networking site, offering possible explanations as to why these terms are deemed so damaging or dangerous by the government.

Though often described with foreboding buzzwords such as "The Great Firewall" and the "censorship regime," Internet regulation in China is rarely either obvious or straightforward. This was the inspiration for China specialist Jason Q. Ng to write an innovative computer script that would make it possible to deduce just which terms are suppressed on China's most important social media site, Sina Weibo. The remarkable and groundbreaking result is Blocked on Weibo, which began as a highly praised blog and has been expanded here to list over 150 forbidden keywords, as well as offer possible explanations why the Chinese government would find these terms sensitive. As Ng explains, Weibo (roughly the equivalent of Twitter), with over 500 million registered accounts, censors hundreds of words and phrases, ranging from fairly obvious terms, including "tank" (a reference to the "Tank Man" who stared down the Chinese army in Tiananmen Square) and the names of top government officials (if they can't be found online, they can't be criticized), to deeply obscure references, including "hairy bacon" (a coded insult referring to Mao's embalmed body). With dozens of phrases that could get a Chinese Internet user invited to the local police station "for a cup of tea" (a euphemism for being detained by the authorities), Blocked on Weibo offers an invaluable guide to sensitive topics in modern-day China as well as a fascinating tour of recent Chinese history.

‘Readers will come away startled at just how fragile the online infrastructure we all depend on is and how much influence China wields – both technically and politically' – Jason Q. Ng, author of Blocked on Weibo 'An urgent and much needed reminder about how China's quest for cyber sovereignty is undermining global Internet freedom’ – Kristie Lu Stout, CNN ‘An important and incisive history of the Chinese internet that introduces us to the government officials, business leaders, and technology activists struggling over access to information within the Great Firewall’ – Adam M. Segal, author of The Hacked World Order Once little more than a glorified porn filter, China’s ‘Great Firewall’ has evolved into the most sophisticated system of online censorship in the world. As the Chinese internet grows and online businesses thrive, speech is controlled, dissent quashed, and attempts to organise outside the official Communist Party are quickly stamped out. But the effects of the Great Firewall are not confined to China itself. Through years of investigation James Griffiths gained unprecedented access to the Great Firewall and the politicians, tech leaders, dissidents and hackers whose lives revolve around it. As distortion, post-truth and fake news become old news James Griffiths shows just how far the Great Firewall has spread. Now is the time for a radical new vision of online liberty.

A groundbreaking and surprising look at contemporary censorship in China As authoritarian governments around the world develop sophisticated technologies for controlling information, many observers have predicted that these controls would be easily evaded by savvy internet users. In Censored, Margaret Roberts demonstrates that even censorship that is easy to circumvent can still be enormously effective. Taking advantage of digital data harvested from the Chinese internet and leaks from China's Propaganda Department, Roberts sheds light on how censorship influences the Chinese public. Drawing parallels between censorship in China and the way information is manipulated in the United States and other democracies, she reveals how internet users are susceptible to control even in the most open societies. Censored gives an unprecedented view of how governments encroach on the media consumption of citizens.

Missing data pose challenges to real-life data analysis. Simple ad-hoc fixes, like deletion or mean imputation, only work under highly restrictive conditions, which are often not met in practice. Multiple imputation replaces each missing value by multiple plausible values. The variability between these replacements reflects our ignorance of the true (but missing) value. Each of the completed data set is then analyzed by standard methods, and the results are pooled to obtain unbiased estimates with correct confidence intervals. Multiple imputation is a general approach that also inspires novel solutions to old problems by reformulating the task at hand as a missing-data problem. This is the second edition of a popular book on multiple imputation, focused on explaining the application of methods through detailed worked examples using the MICE package as developed by the author. This new edition incorporates the recent developments in this fast-moving field. This class-tested book avoids mathematical and technical details as much as possible: formulas are accompanied by verbal statements that explain the formula in accessible terms. The book sharpens the reader’s intuition on how to think about missing data, and provides all the tools needed to execute a well-grounded quantitative analysis in the presence of missing data.
