The next Research & Data Showcase will be live-streamed this Wednesday, 7/16 at 11.30 PT. The streaming link will be posted on the lists a few minutes before the showcase starts and as usual, you can join the conversation on IRC at # wikimedia-research. We look forward to seeing you! Leila This month: *Night Terrors: Day and Night Cycles in Reader and Editor Behaviour*By Oliver Keyes: Using new geolocation tools, we look at reader and editor behaviour to understand how and when people access and contribute to our content. This is largely exploratory research, but has potential implications for our A/B testing and how we understand both cultural divides between reader and editor groups from different countries, and how we understand the transition of people from consumers to contributors. *Using Open Data and Stories to Broaden Crowd Content*By Nathan Matias*: Nathan will share a series of research on gender diversity online and designs for collaborative content creation that foster learning and community. He will also demo a prototype for a system that could leverage open data to attract and support new Wikipedia contributors. *Bio: Nathan Matias, who does research on cooperation across diversity, is a PhD student at the MIT Center for Civic Media and Fellow at the Berkman Center for Internet and Society, where he co-facilitates the Cooperation working group. He also facilitates #1book140, The Atlantic's Twitter Book Club.
