Item Residential Segregation: Hurting or Helping U.S. Hispanic Health?(2009) Nelson, Kyle Anne; Iceland, John; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)U.S. Hispanics experience health disparities that are in part socially determined. My dissertation explores the connections between health and residential segregation for Hispanics and key Hispanic subgroups in metropolitan America. I conduct a multivariate analysis combining individual-level health survey data on Hispanics from the 1997-2002 Urban Institute National Survey of America's Families with metropolitan area-level residential segregation scores from Census 2000. My primary research question is: What is the role of residential segregation in shaping the health disparities of U.S. Hispanics? I compare the link between segregation and health for U.S. Hispanics with African Americans, and evaluate differences among Hispanics by nativity and country of origin. My outcome measures are self-rated health, insurance status, and having a usual source of health care. I find a significant negative effect on health status of residential segregation from whites for U.S. Hispanics even after accounting for compositional factors such as poverty status and education. Consistent with spatial assimilation theory, however, much of the observed negative effects of segregation on health are overshadowed by individual-level socioeconomic characteristics. In support of place stratification theory which emphasizes the relative disadvantage of African Americans as racial minorities in the U.S., I find that African Americans experience modestly greater health disparities associated with segregation than Hispanics. Despite my prediction that health outcomes for foreign-born Hispanics may actually improve with higher segregation, nativity does not significantly alter the link between health and segregation among U.S. Hispanics. I do find a significant interaction between nativity and segregation for Mexicans in the prediction of being uninsured and for Cubans in the prediction of self-rated health. For foreign-born Mexicans, segregation is more of a disadvantage in the prediction of being uninsured. The only evidence I find of any positive or protective link between segregation and health is for Cuban-origin Hispanics whose odds of reporting good self-rated health increase with higher levels of segregation. While segregation has a positive association with health status for both U.S.-born and foreign-born Cubans, the effect is substantially stronger for the foreign born. This research highlights the importance of examining residential segregation as a social determinant of health, and reveals important nuances in the link between health and segregation for nativity and country-of-origin subgroups of U.S. Hispanics.Item Biomedical Innovation and the Politics of Scientific Knowledge: A case study of Gardasil(2008) Clark, Aleia Yvonne; Mamo, Laura; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Vaccine development represents a special case where historically, public health priorities are central. Trends of privatization have increased the role played by pharmaceutical and biotech companies in developing new biomedical technologies. As the innovative science behind new medical technologies moves into pharmaceutical laboratories and biotech companies, the "logics of action" that pattern knowledge production shift. This project explores how different logics of action based on commercial investment and public good shaped the development of Gardasil, a new vaccine to prevent cervical cancer. The study found that both the logics of public good and commercial profit significantly shaped the final product. The study also found that variations in the definition of public good allowed for the settlement of tensions between good and profit. The findings have implications for the future of vaccine development, as well as for the analysis of biomedical innovation in our contemporary political economy.
