In the weeks following the first imported case of Ebola in the U. S. on September 29, 2014, coverage of the very limited outbreak dominated the news media, in a manner quite disproportionate to the actual threat to national public health; by the end of October, 2014, there were only four laboratory confirmed cases of Ebola in the entire nation. Public interest in these events was high, as reflected in the millions of Ebola-related Internet searches and tweets performed in the month following the first confirmed case. Use of trending Internet searches and tweets has been proposed in the past for real-time prediction of outbreaks (a field referred to as “digital epidemiology”), but accounting for the biases of public panic has been problematic. In the case of the limited U. S. Ebola outbreak, we know that the Ebola-related searches and tweets originating the U. S. during the outbreak were due only to public interest or panic, providing an unprecedented means to determine how these dynamics affect such data, and how news media may be driving these trends.
Methodology
We examine daily Ebola-related Internet search and Twitter data in the U. S. during the six week period ending Oct 31, 2014. TV news coverage data were obtained from the daily number of Ebola-related news videos appearing on two major news networks. We fit the parameters of a mathematical contagion model to the data to determine if the news coverage was a significant factor in the temporal patterns in Ebola-related Internet and Twitter data.
Conclusions
We find significant evidence of contagion, with each Ebola-related news video inspiring tens of thousands of Ebola-related tweets and Internet searches. Between 65% to 76% of the variance in all samples is described by the news media contagion model.
You’ve probably heard a lot of “futurists” talk about data, but it’s not always clear how data relate to our day to day work in libraries.
Why are data important, and what’s the big deal? Data are not just spreadsheets and numbers, but come in many different shapes, colors, and flavors! In this presentation, we will give an introduction to data, talk about why it is relevant, and demonstrate how to and use data in practical situations. We will also provide innovative examples that will inspire you to connect with your colleagues and patrons!
The Arizona State University Libraries’ fun Library Minute video series brings information about resource and services to a large student body. For the first time, we present a workshop walking through the entire production process from start to finish and offering suggestions on how to fit multimedia into your marketing and outreach strategy. In this session, we will produce a short video with participants in three steps:
1. Conceptualization and Planning.
2. Recording.
3. Editing and Distribution.
Digital Production Manger Matthew Harp will demonstrate the tools and process and elaborate on the use of social media, YouTube, and the Internet Archive in the distribution plan. Together with Mimmo Bonanni and Library Minute Host Anali Perry, we’ll share our tips and tricks for video production using whatever resources are available.
