The Effects of Semantic Role Predictability on the Production of Overt Pronouns in Spanish.

In order to refer in any language, speakers must choose between explicit forms of expression, such as names or descriptions, or more ambiguous forms like pronouns. Current models suggest that reference form is driven by subjecthood, where speakers in English choose pronouns for the subject, and speakers of null pronoun languages like Spanish or Italian use null pronouns. We test this generalization by examining the effect of a different factor, thematic role predictability, on reference production in Spanish.

Developing and Testing the Detén El Zika Campaign in Puerto Rico.

Responding to an emerging health threat often requires rapid deployment of behavior change communication. Health communication best practices include developing and testing draft messages and materials to ensure that they resonate with and inspire priority groups to act. However, when faced with an emergency health threat, the timeline for these activities can be compressed from months to weeks.

A Mental Models Approach to Assessing Public Understanding of Zika Virus, Guatemala.

Mental models are cognitive representations of phenomena that can constrain efforts to reduce infectious disease. In a study of Zika virus awareness in Guatemala, many participants referred to experiences with other mosquitoborne diseases during discussions of Zika virus. These results highlight the importance of past experiences for Zika virus understanding.

Analysis of low level radioactive metabolites in biological fluids using high-performance liquid chromatography with microplate scintillation counting: method validation and application.

TopCount, a microplate scintillation counter (MSC), has been recently employed as an off-line liquid radiochromatographic detector for radioactive metabolite profile analysis. The present study was undertaken to validate TopCount for metabolite profiling with respect to sensitivity, accuracy, precision and radioactivity recovery. Matrix effects of various human samples on TopCount performance and capability of MSC for volatile metabolite analysis were also investigated.
