Assistant Professor Jessie Chin has received a $389,810 grant from the National Institutes of Health (NIH) to identify false information about the HPV vaccine and model its impact on risk perceptions.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the U.S., with over 34,000 new HPV-related cancers diagnosed annually, according to the Centers for Disease Control and Prevention. An HPV vaccine, which was approved by the Food and Drug Administration (FDA) in 2006, is recommended as part of routine vaccinations for school-aged children. However, the vaccine's uptake remains low in part because of incorrect perceptions of vaccination risks, which has been linked to the spread of false information about the vaccine.

"I've been working on how to promote an accurate comprehension of health information among adults with varying degrees of health literacy. While people with inadequate health literacy are vulnerable to health misinformation, people with adequate health literacy may also fail to identify health misinformation, especially when it has been delivered from known social connections," Chin said of how the project originated.

Chin and her collaborators from the University of Illinois at Chicago and University of Chicago will build a model to identify false HPV-vaccine information on Twitter and demonstrate its impact on individual risk perceptions.

"We propose a novel approach to leverage machine learning, natural language processing, network analysis, crowdsourcing/expert data annotation, psycholinguistic analysis, and statistical modeling to investigate the false HPV-vaccine information collectively (in terms of its detection and propagation patterns) and individually (in terms of its impact and underlying cognitive mechanisms)," she said.

According to Chin, the project's findings will provide important contributions toward understanding the impact of false health information on HPV vaccination behavior and could be expanded to other health topics. The project will also address the National Cancer Institute priorities in promoting HPV vaccines and combating misinformation in cancer prevention and control.

Chin holds a BS in psychology from National Taiwan University, an MS in human factors, and a PhD in educational psychology with a focus on cognitive science in teaching and learning from the University of Illinois at Urbana-Champaign.

New project to help scientists mitigate risks of environmental pollutants

In addition to killing insects and weeds, pesticides can be toxic to the environment and harmful to human health. A new project led by Associate Professor Dong Wang and Huichun Zhang, Frank H. Neff Professor of Civil Engineering at Case Western Reserve University, will help scientists mitigate the environmental and ecological risks of pollutants such as pesticides and develop remediation strategies for cleaner water, soil, and air. The researchers have received a three-year, $402,773 National Science Foundation (NSF) grant for their project, "Machine Learning Modeling for the Reactivity of Organic Contaminants in Engineered and Natural Environments."

New course focuses on the social history of games and gaming

The iSchool has introduced a new course for undergraduate students who are interested in gaming. Social History of Games & Gaming (IS 199 SHG) is a survey of the history of gaming from the ancient world through the twentieth century and its impact on science, society, and culture. Taught by Teaching Associate Professor David Dubin, the course fulfills a general education requirement for students majoring in information sciences. It is taught in a lecture and discussion format, engaging students with the material and promoting participation.
