Associations of Topics of Discussion on Twitter With Survey Measures of Attitudes, Knowledge, and Behaviors Related to Zika

The results demonstrated that it is possible to uncover topics of discussions from Twitter communications that are associated with the Zika-related attitudes, knowledge, and behaviors of populations over time. Social media data can be used as a complementary source of information alongside traditional data sources to gauge the patterns of attitudes, knowledge, and behaviors in a population.

No Missing Link: Knowledge Predicts Acceptance of Evolution in the United States

Most Americans reject some or all parts of evolutionary theory, contrary to the scientific consensus. Americans’ attitudes toward evolution at least partially depend on their religious or political values, and prior work has argued that knowledge of the theory plays a negligible role. But there have been no systematic, large-scale attempts to measure the public’s knowledge of evolutionary theory, which means that claims about a lack of significant impact of evolution knowledge on evolution acceptance may be premature.

Risky movies, risky behaviors, and ethnic identity among Black adolescents

The present study uses survey data from an online sample of 1000 Black adolescents and content analysis ratings on top-grossing 2014 films and 2013/2014 Black-oriented films. The type of movie (i.e., mainstream or Black-oriented) through which Black adolescents are exposed to risky health portrayals is important for understanding its relationship to their behavior, and variations by ethnic identity were limited to sex content.

Disruption, Demonization, Deliverance, and Norm Destruction: The Rhetorical Signature of Donald J. Trump

During his first 100 days as the 45th president of the United States, Donald J. Trump launched Twitter attacks against “Fake Tears Chuck Schumer,” members of the Republican Freedom Caucus, and a district court judge; accused his predecessor of “wiretapping” his phone, though there was no evidence for the claim; and baffled observers by appearing to lament a nonexistent terrorist attack in Sweden. Here we argue not simply that Trump’s norm-shattering rhetoric deviates from that of his predecessors but also that his discursive patterns constitute a double-edged rhetorical identity or signature.

Digital Media and Risks for Adolescent Substance Abuse and Problematic Gambling

Digital media provide increased opportunities for both marketing and social transmission of risky products and behavior. We briefly review what is known about adolescent exposure to favorable presentations of addictive substances, such as alcohol, tobacco, and marijuana, as well as behaviors such as gambling, on social and other online media. Our understanding of these influences and whether they require greater regulation is still developing, and recommendations for future research to address these gaps in our understanding are described.

Executive Function Capacities, Negative Driving Behavior and Crashes in Young Drivers

Motor vehicle crashes remain a leading cause of injury and death in adolescents, with teen drivers three times more likely to be in a fatal crash when compared to adults. One potential contributing risk factor is the ongoing development of executive functioning with maturation of the frontal lobe through adolescence and into early adulthood. This review points to an urgent need for systematic research to inform development of more effective training and interventions.
