3d Musculoskeletal Analysis Of The Rhea Americana Forelimb And Implications For The Evolution Of Avian Flight, Sarah Elizabeth Guzinski

USF Tampa Graduate Theses and Dissertations

To understand the evolutionary gain, and loss, of avian powered flight, attention must be paid to the wing morphology of species across these transitions. However, paleognaths, while being the most well-known flightless birds, have greatly understudied forelimbs. Additionally, current literature regarding their forelimb anatomy generally lacks a three-dimensional (3D), biomechanical approach. Among the flightless paleognaths, the rhea is notable in having the least reduced forelimb. Though not used for flight, the wings of rheas are used in other behaviors such as courtship and threat display, as well as nest defense. In this study, I investigate the forelimb anatomy of an …

For Love Or Money: Investor Motivations In Equity-Based Crowdfunding, Jason C. Cherubini

USF Tampa Graduate Theses and Dissertations

Crowdfunding is an increasingly popular method for entrepreneurial ventures to raise financing from a large number of small supporters (the “crowd”) instead of raising it through a small number of larger supporters. Crowdfunding is normally conducted through online platforms such as Kickstarter and Indiegogo, where the entrepreneurial venture runs a campaign directly seeking support from individual funders. Most of the research into crowdfunding to date has been focused on what elements of the crowdfunding campaign lead to eventual successful funding, especially in the rewards-based crowdfunding space. The comparatively new equity-based crowdfunding has not been as heavily researched and is technically …

Selective Framing And Narrative As Anthropocentric Agents In Yellowstone: America’S Eden, Breanna Lee Hansen

Exposure Characteristics Of Environmental Chemicals By Life Stages, Nisha Vijayakumar

USF Tampa Graduate Theses and Dissertations

Environmental chemicals are ubiquitous and can contribute to human exposure. These exposures can result in long-term health consequences if they occur in early life. However, exposures to environmental chemicals are not evenly distributed throughout childhood. As a result, there exists variation in the levels of chemical exposure depending on the developmental stages, pathways of exposure, and broader systemic factors. However, in early life, limited research exists on exposures to environmental chemicals, particularly phthalates, pesticides, and polycyclic aromatic hydrocarbons (PAHs). In addition, environmental exposures to phthalates, pesticides, and PAHs, considering life stages, have not been fully explored. Hence it is imperative …

Defining A Factor-Induced Signaling Signature For Endothelial Tubulogenesis, Sprouting, And Pericyte Recruitment, Prisca Kuanting Lin

USF Tampa Graduate Theses and Dissertations

Endothelial cells (ECs) form the inner lining of blood capillary walls. Our laboratory has developed a serum-free, defined Factor system that allows for human ECs to sprout, form lumens and tube networks, recruit pericytes, and induce capillary basement membrane deposition in 3D extracellular matrices. We have shown that the Factor system drives morphogenesis through the activation of multiple signaling pathways; however, we do not know if all factors in the Factor system are needed to induce maximal EC morphogenesis. If so, we have yet to identify why the Factors are critical to the model other than that they induce activation …
