How Far-Right Populism Harms Ethnic Minorities’ Health: The Case Of The United States, Dina Rosenberg

Working Papers Series

Public health is a political issue, and the health of ethnic minorities is a key component of it. We argue that far-right populism, whether grassroots or elitist, harms the health of immigrants and minorities. Anti-minority attitudes and policies—such as health chauvinism promoted by far-right populists—along with hate rhetoric and ensuing personal and institutional discrimination create a climate of hostility that negatively affects health outcomes in underprivileged communities. We hypothesize that immigrants and ethnic minorities living in such a climate are more likely to experience health problems and underutilize healthcare. To test this, we leverage the significant variation between U.S. states …

Walk A Mile: Exploring Cause-Based Charity Event Participation As A Catalyst For Increasing Physical Activity Behavior, Kimberly S. Fasczewski, Andrey A. Sanko Posada, Meg Hopkins

Journal of Social, Behavioral, and Health Sciences

Despite the known benefits of physical activity (PA), more than half of U.S. adults do not meet the American College of Sports Medicine’s PA recommendations for health, often resulting in negative health outcomes. Developing programming that increases motivation for PA participation is critical for healthcare professionals to combat physical inactivity. Previous research has demonstrated that framing disease-based PA charity fundraising events as “helping a cause” improved motivation for PA due to the individual’s emotional connection to the cause. There is currently no congruent research on motivation for participation in cause-based charity events. Behavioral economics theory posits that cognitive, emotional, and …

Is Ride-Hailing A Potential Solution For Older Adults After Driving Cessation? The Role Of Objective And Perceived Accessibility, Minju Kim Song

Dissertations and Theses

Due to age-related physical and cognitive changes, older drivers have a greater risk of crashes and are restricted by age-dependent regulation. Nonetheless, many older adults in the United States maintain a car-dependent lifestyle and still prefer driving. When driving cessation or reduction becomes necessary, a primary concern is finding suitable alternative transportation modes. However, the availability of alternative transportation modes does not guarantee their actual use of these options.

As a relatively new transportation mode, ride-hailing services, such as Uber and Lyft, offer on-demand, door-to-door transportation and may be a feasible transportation solution for older adults who stop driving. While …
