The Color Of Disease: Race Science, Pandemic Influenza, And The Rise Of Epidemiology In The Segregated South, Andrew Kishuni

Graduate Thesis and Dissertation 2023-2024

This thesis evaluates the relationship between race science and eugenics, statistical epidemiology and Southern public health thought, African American health, and the 1918-1920 influenza pandemic. Historians have neglected the flu as an important epidemiological event in Southern history and historiography. To demonstrate the significance of the flu, this thesis makes several arguments based on research from new qualitative and quantitative evidence. The chief argument is that African Americans suffered disproportionately compared to whites in the South, challenging the consensus that the flu affected both races equally. Segregation did not protect African Americans from the flu. In some cases, African Americans …

Interaction Of Sexual Orientation, Racial, And Gender Discrimination On Mental Health Outcomes, Rebekah Kanefsky

Graduate Thesis and Dissertation 2023-2024

Experiencing discrimination is associated with greater risk of developing mental health symptoms. Important theories on the mental well-being of people who identify with underrepresented groups suggest that poorer outcomes are not simply associated with identifying with an underrepresented group. Rather, “minority stressors” (e.g., discrimination) drive poor mental health outcomes. Despite the connection between mental health and discrimination, there has been less research focused on the combined impact of multiple forms of discrimination and how they interact for individuals who possess multiple, underrepresented identities. Further, significantly less research has been conducted utilizing quantitative methodology. To investigate the relationship between different forms …
