Hi Everyone, The next Wikimedia Research Showcase will be live-streamed Wednesday, September 19 2018 at 11:30 AM (PDT) 18:30 UTC. YouTube stream: https://www.youtube.com/watch?v=OY8vZ6wES9o As usual, you can join the conversation on IRC at #wikimedia-research. And, you can watch our past research showcases here. <https://www.mediawiki.org/wiki/Wikimedia_Research/Showcase#Upcoming_Showcase> Hope to see you there! This month's presentations is: The impact of news exposure on collective attention in the United States during the 2016 Zika epidemicBy *Michele Tizzoni, André Panisson, Daniela Paolotti, Ciro Cattuto*In recent years, many studies have drawn attention to the important role of collective awareness and human behaviour during epidemic outbreaks. A number of modelling efforts have investigated the interaction between the disease transmission dynamics and human behaviour change mediated by news coverage and by information spreading in the population. Yet, given the scarcity of data on public awareness during an epidemic, few studies have relied on empirical data. Here, we use fine-grained, geo-referenced data from three online sources - Wikipedia, the GDELT Project and the Internet Archive - to quantify population-scale information seeking about the 2016 Zika virus epidemic in the U.S., explicitly linking such behavioural signal to epidemiological data. Geo-localized Wikipedia pageview data reveal that visiting patterns of Zika-related pages in Wikipedia were highly synchronized across the United States and largely explained by exposure to national television broadcast. Contrary to the assumption of some theoretical models, news volume and Wikipedia visiting patterns were not significantly correlated with the magnitude or the extent of the epidemic. Attention to Zika, in terms of Zika-related Wikipedia pageviews, was high at the beginning of the outbreak, when public health agencies raised an international alert and triggered media coverage, but subsequently exhibited an activity profile that suggests nonlinear dependencies and memory effects in the relationship between information seeking, media pressure, and disease dynamics. This calls for a new and more general modelling framework to describe the interaction between media exposure, public awareness, and disease dynamics during epidemic outbreaks. Deliberation and resolution on WikipediaA case study of requests for commentsBy *Amy Zhang, Jane Im*Resolving disputes in a timely manner is crucial for any online production group. We present an analysis of Requests for Comments (RfCs), one of the main vehicles on Wikipedia for formally resolving a policy or content dispute. We collected an exhaustive dataset of 7,316 RfCs on English Wikipedia over the course of 7 years and conducted a qualitative and quantitative analysis into what issues affect the RfC process. Our analysis was informed by 10 interviews with frequent RfC closers. We found that a major issue affecting the RfC process is the prevalence of RfCs that could have benefited from formal closure but that linger indefinitely without one, with factors including participants' interest and expertise impacting the likelihood of resolution. From these findings, we developed a model that predicts whether -- Sarah R. Rodlund Technical Writer, Developer Advocacy <https://meta.wikimedia.org/wiki/Developer_Advocacy> srodlund(a)wikimedia.org
