"Narco" Emotions: Affect and Desensitization in Social Media during the Mexican Drug War
Social media platforms have emerged as prominent information sharing
ecosystems in the context of a variety of recent crises, ranging from mass
emergencies, to wars and political conflicts. We study affective responses in
social media and how they might indicate desensitization to violence
experienced in communities embroiled in an armed conflict. Specifically, we
examine three established affect measures: negative affect, activation, and
dominance as observed on Twitter in relation to a number of statistics on
protracted violence in four major cities afflicted by the Mexican Drug War.
During a two year period (Aug 2010-Dec 2012), while violence was on the rise in
these regions, our findings show a decline in negative emotional expression as
well as a rise in emotional arousal and dominance in Twitter posts: aspects
known to be psychological markers of desensitization. We discuss the
implications of our work for behavioral health, facilitating rehabilitation
efforts in communities enmeshed in an acute and persistent urban warfare, and
the impact on civic engagement.Comment: Best paper award at the 32nd annual ACM conference on Human factors

Networks of Gratitude: Structures of Thanks and User Expectations in Workplace Appreciation Systems
Appreciation systems--platforms for users to exchange thanks and praise--are
becoming common in the workplace, where employees share appreciation, managers
are notified, and aggregate scores are sometimes made visible. Who do people
thank on these systems, and what do they expect from each other and their
managers? After introducing the design affordances of 13 appreciation systems,
we discuss a system we call Gratia, in use at a large multinational company for
over four years. Using logs of 422,000 appreciation messages and user surveys,
we explore the social dynamics of use and ask if use of the system addresses
the recognition problem. We find that while thanks is mostly exchanged among
employees at the same level and different parts of the company, addressing the
recognition problem, managers do not always act on that recognition in ways
that employees expect.Comment: in Tenth International AAAI Conference on Web and Social Media, 201
Ball-AR: Fostering Playful Co-Located Interaction Through Environment-centric Physical Activity with AR
We present Ball-AR, an augmented reality (AR) game where two players in the
same physical space attempt to hit each other with virtual dodgeballs overlaid
on the physical world. Researchers have studied AR's potential for fostering
co-located interaction and physical activity; however, they have not
investigated the impacts of physical activity and physical environment on user
experiences and interaction. We created an AR dodgeball game centered around
encouraging physical activity and harnessing the physical environment. We then
evaluated the game with five dyads to analyze the impacts of these design
choices on the quality of gameplay and interaction between players. We found
that physical activity and the shared physical space created memorable
experiences and interactions among participants, although participants desired
a more augmented and immersive experience
