Overwintering And Early Season Amplification Of Eastern Equine Encephalitis Virus In The Southeastern United States, Andrea Bingham
USF Tampa Graduate Theses and Dissertations
Eastern equine encephalitis virus (EEEV) is a highly pathogenic arbovirus that causes severe disease, with a mortality rate of approximately 30-35% in humans and 80-90% in horses. Studies dating back to the 1930's have identified many of the epidemiological and ecological aspects of the virus. However, there are several aspects of EEEV's transmission cycle that remain unclear. In the northeastern states, transmission is seasonal, peaking in the late summer months, while in Florida there is year-round transmission of EEEV. Recent phylogenetic studies have also suggested that Florida may serve as a reservoir for EEEV; the virus may periodically be introduced …

Pathways Of Embodiment: Drug Use Among Adolescents In Popay[Aacute]N Colombia, Sarah Louise Fishleder
USF Tampa Graduate Theses and Dissertations
This research examines the interrelated biological and cultural factors that determine pathways by which recreational drug use is manifest to addiction in the lives of youth aged 12-18 in Popay[aacute]n, Colombia. It utilizes existing data from mixed methods research conducted between 2004-2005 examining epidemiological risk factors, drug use, perceptions about drugs, and a biological phenomenon of the brain known as incentive salience. Perceptions and experiences related to drugs were gathered using structured methods. MDS and hierarchical plots of drug perceptions are presented in order to demonstrate the power of culture and expectation on perception and choice. Structural equation modeling was …
