Carlos Castillo-Chavez's tenure at Cornell University with Simon Levine, also marks the beginning of my life as his daughter. I was nine months old when I arrived to Ithaca, and my recollections of my father in elementary school and middle school were of him furiously writing equations at his desk, or outside on the chalk board in our shed, or on napkins, notepads or anything he could get his h...

The tendency for people to rate attitude-confirming information more positively than attitude-disconfirming information (biased assimilation) was studied in a naturalistic context. Participants watched and evaluated the first 1996 Presidential Debate between Bill Clinton and Bob Dole. Regression analyses revealed that predebate attitudes but not expectations predicted postdebate argument evalua...

Evidence of this exists not just in television and magazine ads extolling the promises of Viagra and Nexium, but also in a few statistics. First, forty-six percent of Americans use at least one prescription drug daily. Further, in 2001, 3.1 billion prescriptions were issued in the United States at a cost of $13...

We examine the growth, survival, and context of 256 novel hashtags during the 2012 U.S. presidential debates. Our analysis reveals the trajectories of hashtag use fall into two distinct classes: “winners” that emerge more quickly and are sustained for longer periods of time than other “also-rans” hashtags. We propose a “conversational vibrancy” framework to capture dynamics of hashtags based on...

This experimental research examines how different presentation modalities in presidential debates and post-debate spin influence the ability to form evaluations about candidates’ character, shape perceptions of their incivility, and alter judgments of political trust and news credibility. Results indicate that these experimental factors work together to encourage character judgments, diminish p...

It is increasingly common for researchers in the humanities and social sciences make use of computational analysis of large datasets to answer research questions. One field where computational analysis is getting traction is political science. In this paper, we leverage a particularly rich dataset from the domain of political science that contains the transcript of one of the 2012 presidential ...
