Viviana Chiu Sik Wu, Assistant Professor of Public Policy, recently published new research titled “Who Leads and Who Echoes? Tracing Message Similarity Network of #ClimateChange Advocacy on Twitter.” In the article, Wu and co-author Weiai Wayne Xu (Communications) analyze how non-profit organizations advocate for and shape climate change policy through conversations on Twitter. They find that climate obstruction non-profits may not be frequent tweeters, but their voices are highly reciprocal. They also find that messaging from non-profits, regardless of perspective, is most echoed by the public as opposed to elite audiences.
