Christopher Cairns joins the hosts of Sinica for a discussion of his forthcoming paper, co-authored with Allen Carlson, scheduled for publication in China Quarterly. Why are we so interested in this topic? Because Cairns and his colleagues at Cornell have actually found a way to measure the extent of government censorship over time, and their research has unearthed some particularly interesting ideas about the relationship between anti-Japanese nationalism and the extent of censorship on Weibo.
