Query: "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.
