THE FUTURE IS KID STUFF IN HIS INAUGURAL ADDRESS IN JANUARY 2009, President Obama alluded to an often-quoted passage from the Bible and adapted it to recast America’s idea of itself: “We remain a young nation,” he said, “but in the words of Scripture, the time has come to set aside childish things.” By articulating his exhortation through the opposition of youth and age, Obama sought to reframe...

This study argues that President Obama’s strong association with an issue like health care should polarize public opinion by racial attitudes and race. Consistent with that hypothesis, racial attitudes had a significantly larger impact on health care opinions in fall 2009 than they had in cross-sectional surveys from the past two decades and in panel data collected before Obama became the face ...

This study finds support for agenda melding and further validates the Network Agenda Setting (NAS) model through a series of computer science methods with large datasets on Twitter. The results demonstrate that during the 2012 U.S. presidential election, distinctive audiences “melded” agendas of various media differently. “Vertical” media best predicted Obama supporters’ agendas on Twitter wher...

In an election year, political messaging can become feisty or even violent. In the 2012 U.S. presidential election, Americans were inundated with statements that metaphorically referred to violence, such as “Romney slams Obama” and”Romney slaughtered Obama.” Such expressions grab our attention and resonate with our understanding of actual physical violence. Despite their frequent use in electio...

We annotate individual posts following the approach in [1], [2]. Tweets are grouped by topic based on included topic hashtags. For example, tweets relating to the topic of president Barack Obama contain the hashtag #obama within them. The topic-related tweets often contain other hashtags which we assign a preliminary sentiment probability (positive and negative) using the Multinomial Naive Baye...

For this project, we attempted to classify the political sentiment of tweets containing the case-insensitive string ‘Obama’ in an effort to automatically gauge the public opinion of US President Barack Obama. To accomplish this goal we investigated rule-based, supervised, and semi-supervised learning methods. Our main approach involved bootstrapping an ngram-feature-based maximum entropy classi...

n t h e l e a d-u p to the presidential election, then-presidential candidate Senator Barack Obama outlined a comprehensive place-based agenda he would, if elected, pursue to improve the lives of low-income residents in urban neighborhoods across the country. In that speech, delivered in July 2007, Senator Obama proposed to infuse poor neighborhoods with a mix of maternal and early childhood fa...

This paper reports an experiment which explores how our semantic representations of individual objects are organized and accessed in memory and how these representations are inter-linked with those of other individuals. A priming experiment was conducted to investigate the relations between singular representations of famous individuals from four categories (person, building, artwork and produc...

Images of Black Americans are becoming remarkably diverse, enabling Barack Obama to defy simple-minded stereotypes and succeed. Understood through the Stereotype Content Model’s demonstrably fundamental trait dimensions of perceived warmth and competence, images of Black Americans show three relevant patterns. Stereotyping by omission allows non-Blacks to accentuate the positive, excluding any ...
