This analysis centers on the situation in Tampa before, during, and after World War II, and in doing so it assesses the …

Propaganda Of Car Ecotourism In Glacier National Park, Hanna Y. Mohammed

Honors Undergraduate Theses

This paper discusses the promotion of car ecotourism and its impact on Glacier National Park. Coinciding with the creation of the park's flagship Going-to-the-Sun Road from 1921 to 1932, both the state and the private sector presented the image of the newly commodified automobile as a vehicle to explore nature with. Historically, national parks have served the interests of the middle and upper classes, by suppressing marginalized communities, primarily through forced relocation in order to clear the lands for creation of the parks. The public's conception of the “wilderness” drastically changed during the time the car was commodified, as nature …

Time-Specific Safety Performance Functions For Different Advanced Traffic Management Strategies, Jingwan Fu

Electronic Theses and Dissertations, 2020-2023

Time-specific Safety Performance Functions (SPFs) were proposed to achieve accurate and dynamic crash frequency predictions and bridge the gap between annual crash frequency prediction and real-time crash likelihood prediction. This research proposed time-specific SPFs considering the temporal variation in crashes and traffic characteristics. Firstly, the developed time-specific SPFs that include different ATM strategies (i.e., HOV, merge, diverge and reversible lanes segments) were investigated in this study. The results indicate that the traffic turbulence during specific hours would relate to crash occurrence. Further, the variables that represent the speed and occupancy differences between the HOV lanes/reversible lanes and general-purpose lanes were …

Local-Level Maternal And Infant Health: A Mixed-Methods Analysis Of The Relationship Between Social Determinants Of Health, Maternal And Infant Health Outcomes, And Public Health Programs In Florida, Jacquelyn Reiss

Electronic Theses and Dissertations, 2020-2023

Current data highlight significant disparities in infant and maternal health (IMH) outcomes both when comparing outcomes to other countries and between groups within the U.S. Previous studies indicate that disparities in health outcomes are caused by health inequities. Health inequities are a result of marginalized groups historically being denied resources and exposed to increased risk directly impacting health. These resources and risks are considered social determinants of health (SDoH), such as income, housing, transportation, and access to care. Although SDoH influence individuals across multiple levels of society, communities are sites where individuals directly access protective resources and are potentially exposed …

Exploring Population Structure And Diversity Across Time In Population Of American Flamingos (Phoenicopterus Ruber), Jessica Folsom

Electronic Theses and Dissertations, 2020-2023

Dispersal and connectivity within a population often promotes overall diversity and adaptive potential, therefore a disruption of existing patterns of connectivity by local extinction can have significant consequences for the affected species. However, the extent of these impacts on recovery is not always known. American flamingos (Phoenicopterus ruber) present an ideal opportunity to investigate how changes in gene flow influence within population diversity and genetic structure over the span of a century for a recovering population. Flamingos were highly sought-after by hunters for their meat and feathers, and as a result, the Florida population was extirpated by the beginning of …

Radioprotectant Ceria Nanoparticles Drug Delivery System To Reduce Reactive Oxygen Species Levels And Mitigate Spaceflight Osteopenia, Balaashwin Babu

Electronic Theses and Dissertations, 2020-2023

In the extreme environment of space, radiation induced health issues is a major concern. The ability to induce higher levels of free radicals and reactive oxidative species (ROS) are factors to be addressed. Ceria nanoparticles (CNPs) can provide a means to scavenge ROS through regenerative redox coupling that occurs on the surface and acts as a radioprotectant. Additionally, the defect levels in CNP can be categorized by the Ce3+/Ce4+ ratio with a high ratio indicating superoxide scavenging, a radical species with high oxidative potential. However, engineering a specialized Ce3+ NP often requires a harsh reducing agent. We hypothesized a wet-chemical …

I find that when firm ESG coverage intensifies, its ESG ratings improve, its …

Topographical Distribution And Morphology Of Sympathetic Postganglionic Innervation And Chronic Intermittent Hypoxia (Cih) Induced Remodeling Of The Whole Heart At Single Cell/Axon/Varicosity Scale, Ariege Bizanti

Electronic Theses and Dissertations, 2020-2023

The sympathetic nervous system is crucial for controlling multiple cardiac functions and its overactivity is associated with many cardiovascular diseases (CVD). Chronic intermittent hypoxia (CIH) is a current model for sleep apnea, which constitutes a major risk factor for CVD through sympathetic overactivity. However, a comprehensive neuroanatomical map of the sympathetic innervation of the heart is unavailable which impedes our understanding of the remodeling of this map in pathological conditions. First, we used a combination of state-of-the-art techniques, including flat-mount tissue processing, immunohistochemistry for tyrosine hydroxylase (TH, a sympathetic marker), confocal microscopy and Neurolucida 360 software to trace, digitize, and …
