Trial & Error: Royal Authority & Families In The Colonization Of The British Floridas, 1763-1784, Deborah L. Bauer

USF Tampa Graduate Theses and Dissertations

This dissertation will examine the relationship between families, the British Crown, and colonization patterns in mid-eighteenth-century Florida. Agents of royal authority, such as colonial governors, and White, European, Protestant families, would serve as the bulwark upon which the Crown would design and implement its ideal colonization scheme. Carefully created by royal officials, adherence to the plan would result in the successful establishment and growth of loyal and productive colonies. Noncompliance ultimately foreshadowed failure. The state used the social unit of families in East and West Florida as a "tool of empire” to ensure the political, economic, and military success of …

Ecological Responses Of Seascape Heterogeneity, Dinorah H. Chacin

USF Tampa Graduate Theses and Dissertations

A core aim of landscape ecologists as well as conservation and management practices has been to understand how processes that structure communities vary as a function of landscape context. Landscape heterogeneity (i.e. landscape composition, configuration) and fine-scale habitat characteristics can influence ecological interactions across habitat patches at a range of scales. Therefore, the main objective of this work is to apply a landscape ecology perspective to understand how seascape heterogeneity can influence demographic rates, community patterns, and ecological processes. To accomplish this overall goal, I conducted a literature review on oyster reefs from a seascape ecology perspective (Chapter 1) and …

Lung Cancer Cells Survive Egfr Tki Exposure Through Upregulation Of Cholesterol Synthesis, Mark Howell

USF Tampa Graduate Theses and Dissertations

Lung cancer is the number one cause of cancer related death in both males and females. About 20% of all non-small cell lung cancer (NSCLC) patients are expected to harbor an epidermal growth factor receptor (EGFR) activating mutation. EGFR inhibitors have been shown to provide clinical benefits over chemotherapy for lung cancer patients with EGFR activating mutations. However, despite the initial clinical responses to these EGFR targeted therapies, long-term efficacy is not possible because acquired drug resistance hampers the effectiveness of these therapies. We found that a fiber inspired smart scaffold (FiSS) platform established in our laboratory allows growth of …

Construction Of G-Quadruplexes Via Self-Assembly: Enhanced Stability And Unique Properties, Ying He

USF Tampa Graduate Theses and Dissertations

This dissertation mainly contains three parts: 1) The construction of well-defined G8-octamers through the monomer conformational design. 2) The construction of cross-layer interactions in the G8-octamer for enhanced stability in H-bond competitive solvents. 3) Design and synthesis of 8-triazole guanosine with photoluminescent properties.

Through the structural conformational design, we have developed a new class of guanosine derivatives with modification on guanine (8-aryl) and ribose (2’,3’-isopropylidene). This unique design has led to the formation of the first discrete G8-octamer with structure characterized by NMR, MS and single crystal X-ray diffraction. The selectivity between monovalent (K+) and divalent cat-ions (Ba2+ and Sr2+) …

Identifying Employees Who Fit With Electronic Communication Styles, Britany Telford Mills

USF Tampa Graduate Theses and Dissertations

Electronic communication is no longer solely used by globally dispersed work teams. It is an integral part of today’s organizations whether they include remote workers or not. Therefore, it is important to understand how employees perceive electronic communication from their supervisor and the impact that perception has on the worker. Researchers have been adamant in the assertion that relationship-oriented communicated is better conducted face-to-face. The current study seeks to add to the existing body of research by (1) examining how the proportion of relationship-oriented communication that is electronic affects both subordinate perceptions of communication openness and subordinate job satisfaction, and …

Use Of Spectrofluorometry To Detect Petroleum Hydrocarbons In The Marine Environment, Mary Iris Abercrombie

USF Tampa Graduate Theses and Dissertations

The genesis of this research was the Deepwater Horizon oil spill, which discharged petroleum and gas into the Gulf of Mexico for 87 days in 2010. High-resolution fluorescence spectroscopy was employed for the detection of petroleum in seawater samples following the oil spill. Fluorescence arises from the chemical structure of π-bonding in C=C bonds, especially those in aromatic structures. Spectrofluorometry was also used to observe and track the formation of petroleum plumes in seawater undergoing controlled physical dispersion in a wave tank, both with and without the addition of chemical dispersant. Further, the changing fluorescence characteristics of a broad range …

Innovating Green Stormwater Infrastructure For Nutrient Management: Long-Term Field And Modeling Studies Of Conventional And Modified Denitrifying Bioretention Systems, Emma V. Lopez-Ponnada

USF Tampa Graduate Theses and Dissertations

Urban stormwater and nutrient management are increasingly important topics to address globally, as coastal urbanization increases, disturbing the natural landscape, hydrology, and water quality. Untreated urban stormwater runoff carries pollutants that enter our waterways, such as rivers and marine environments, which serve as drinking water sources, recreational sites, and locations for economic livelihood. One pollutant and nutrient of concern for water quality is reactive nitrogen (N). Since pre-industrial time, reactive nitrogen has doubled from human activity. When found in excess in waterways, nitrogen causes an overabundant growth of algae, which can result in eutrophic and hypoxic conditions, impacting ecosystems, human …

Development Of A Voxel-Based Monte Carlo Radiation Dosimetry Methodology For A Targeted Alpha Particle Therapy, Christopher John Tichacek

USF Tampa Graduate Theses and Dissertations

The use of targeted ligands to deliver radioisotopes directly to tumor cells is a promising therapeutic strategy. Because of the short path length and high LET of alpha particles, targeted alpha particles are ideal for treating metastatic disease while minimizing damage to non-targeted tissues. However, clinical methods for determining 3D radiation dosimetry in patients with multiple metastatic lesions are needed to support clinical translation of novel targeted alpha particle therapies for personalized treatment, especially in patients that have previously received radiotherapy. Recently interest in novel radiopharmaceutical development has grown significantly. However, compared to external beam radiation therapy, progress in customizing …

Trajectory Based Traffic Analysis And Control Utilizing Connected Autonomous Vehicles, Yu Wang

USF Tampa Graduate Theses and Dissertations

Recent scholars have developed a number of stochastic car-following models that have successfully captured driver behavior uncertainties and reproduced stochastic traffic oscillation propagation. While elegant frequency domain analytical methods are available for stability analysis of classic deterministic linear car-following models, there lacks an analytical method for quantifying the stability performance of their peer stochastic models and theoretically proving oscillation features observed in the real world. To fill this methodological gap, this study proposes a novel analytical method that measures traffic oscillation magnitudes and reveals oscillation characteristics of stochastic linear car-following models. We investigate a general class of stochastic linear car-following …

High Ammonia Strength Wastewater Treatment Using Algae, Bacteria And Ion Exchange, Nadezhda Zalivina

USF Tampa Graduate Theses and Dissertations

Nitrogen pollution has been considered one of the major problems of the 21st century. Discharge of nitrogen from improperly treated wastewaters into surface water bodies causes eutrophication and hypoxia, which results in significant environmental, public health and economic damages. In addition to the incoming flow, wastewater treatment plants generate internal highly concentrated ammonium streams, such as anaerobic digestion sidestream. As a current practice, sidestream without prior treatment is returned to the head of the plant, which increases the total incoming nitrogen load by 20-30% and often exceeds the treatment capacity. The most commonly used conventional biological nitrogen removal processes are …

Untapped Potential Of Gorgonian Octocorals For Detecting Environmental Change In Biscayne National Park, Florida, Usa, Selena A. Kupfner Johnson

USF Tampa Graduate Theses and Dissertations

One consequence of dramatic stony-coral loss has been recognition that gorgonian octocorals (Anthozoa: Octocorallia) have emerged among the dominant reef fauna. However, gorgonians are notoriously difficult to field-identify and consequently have been underrepresented in most monitoring efforts resulting in a lack of long-term data. The rich diversity of habitats, close proximity to the urban center of Miami, and connectivity to other areas of Florida have made Biscayne National Park an active location for reef research since its establishment in 1968. As such, a plethora of data (e.g., museum specimen and species abundance data) has been collected and stored in archives …

The Role Of Atypical Protein Kinase C In Colorectal Cancer Cells Carcinogenesis, S M Anisul Islam

USF Tampa Graduate Theses and Dissertations

Colorectal cancer (CRC) is the third most common malignancy and the fourth most common cause of cancer-related death worldwide. CRC is a life-threatening disease due to therapy-resistant cancerous cells. The exact mechanisms of cell growth, survival, metastasis and inter & intracellular signaling pathways involved in CRC are still a significant challenge. Moreover, the treatment of metastatic CRC considered palliative for many years aimed for an improved life, with little hope of a cure, highlighting the need for developing novel targeted therapy for CRC. Hence, investigating new molecular mechanism(s) that lead to colorectal carcinogenesis may give insight into the therapeutic target. …

Biomimetic Light Harvesting In Metalloporphyrins Encapsulated/Incorporated Within Metal Organic Frameworks (Mofs)., Abdulaziz A. Alanazi

USF Tampa Graduate Theses and Dissertations

The Global energy supply relies mostly on fossil fuels and only 10% comes from renewable energy. These places humankind in an unsafe situation as the fossil fuel resources won’t last forever. More efficient use of renewable energy is required sooner than later to meet the growing energy need. A promising approach is to utilize light harvesting chromophores (e.g., porphyrin derivatives) to advance organic photovoltaics and increase its efficiency or to improve photocatalysts. Metal-organic frameworks (MOFs) can be employed to aid the self-assembly of the porphyrin chromophores in a large light-harvesting system comparable to the natural photosystem. The advantage of using …

Perceived Discrimination And Cardiovascular Outcomes In Blacks: A Secondary Data Analysis Of The Heart Score Study, Marilyn Aluoch

USF Tampa Graduate Theses and Dissertations

Despite the consistent reduction in morbidity and mortality associated with cardiovascular disease (CVD) over the last four decades, CVD remains the leading cause of death globally. In the United States, Blacks are disproportionately affected by CVD compared to Whites. Blacks are also more likely to report incidence of perceived discrimination. Perceived discrimination has been linked to cardiovascular risk factors such as smoking, hypertension (HTN), hyperlipidemia, and obesity. However, the relationship between perceived discrimination and cardiovascular outcomes such as stroke, myocardial infarction, acute ischemic syndrome, coronary revascularization, and cardiac death remains unclear. The primary goal of this study was to examine …

Teachers And Administrators Explain How And Why Teachers Change Instructional Methods In A Pre-K Through Eight Catholic School, Judith A. Deeley

USF Tampa Graduate Theses and Dissertations

This qualitative exploratory study explored how and why teachers at four small Catholic schools in the state of Florida transformed by changing instructional methods to offer full integration of science, technology, religion, engineering, arts and mathematics (STREAM) approaches into learning experiences for grades pre-k through eight. There was a time up until the early 2000s that Catholic school enrollment was at capacity and did not require differentiation based upon unique student learning needs. However, students of current times reflect a higher need for educational approaches that are both differentiated and engaging.

Introducing A Mobile Health Care Platform In An Underserved Rural Population: Reducing Assimilations Gaps On Adoption And Use Via Nudges, Joseph Hodges

USF Tampa Graduate Theses and Dissertations

Rural communities are often overlooked when it comes to offering cutting edge consumer healthcare technologies. Mobile applications usually exclude populations in rural demographics due to the infrastructure requirements and available technology in the region. The population studied is a low income rural health plan in southwest Georgia. They are uniquely considered as they have the highest healthcare costs in the U.S. and are compared to healthcare costs among higher income populations like Vail, Colorado. Innovations, such as mobile healthcare applications, have the capacity to offset some of these costs, but even if adoption occurs, this does not guarantee use will …

Amyloid Protein Aggregation And Associated Toxicity, Chamani A. Niyangoda

USF Tampa Graduate Theses and Dissertations

Amyloidosis is a group of diseases in which amyloid fibrils accumulate and deposit into plaques and intracellular inclusions which lead to disruption of the tissue architecture and function. Most of the amyloid diseases are incurable due to a lack of understanding of the amyloid formation, as well as associated toxicity. My research work is focused on three different aspects of amyloid aggregation.

The aim of the first project is to investigate the potential use of deep-blue autofluorescence (dbAF) as an intrinsic optical probe to study amyloid self-assembly. This novel fluorescence signal is excited at the long wavelength edge of the …

Relationship Between Membership In Honors College And Participation In High-Impact Activities And Perceived Gains, Clara H. Ohannes

USF Tampa Graduate Theses and Dissertations

This research study investigated the relationship between membership in the Honors College and senior-level students’ self-reported involvement in high-impact educational activities and their perceived gains from their college experience. This quantitative study analyzed secondary data from the National Survey of Student Engagement (NSSE) collected from senior-level students in Spring 2017 at a large, four-year, public research institution in the southeast United States.

A logistic regression analysis was used to explore the relationships between the involvement in high-impact educational activities and Honors College membership. The relationship between Honors College membership and several high-impact activities were found to be significant (p<.05), which included participation in a leadership role, study abroad, research with faculty and a senior capstone experience. Since membership in Honors was found to significantly contribute to participation in four out of the six high-impact practices listed in NSSE, it could be said that generally, at the particular institution in this study, Honors students are more likely than Non-Honors students to participate in high-impact learning activities.

Then, …

An Ecology Of Care: Training In Dependence And Caretaking In The Witcher 3: Wild Hunt, Elizabeth Rossbach

USF Tampa Graduate Theses and Dissertations

This project investigates the popular open-world fantasy RPG, The Witcher 3: Wild Hunt (CD Projekt RED 2015) and the ways in which the Witcher 3 brings questions of care and dependence to a digital medium so often thought of in terms of violence and/or mastery. Much of the previous discourse on video games, particularly role-playing games, has tended to center on violence and what this might mean for players behavior or the potential real world effects of this violence. Departing from a focus on violence I argue that the Witcher 3, reveals the potentials of open-world RPG video games to …

Self-Assembly Of 2d And 3d Metallo-Supramolecules With Increasing Complexity, Bo Song

USF Tampa Graduate Theses and Dissertations

Synthetic organic chemistry played a crucial role in the construction of molecules through the formation and dissociation of covalent bonds. However, the laborious synthetic procedures as well as the low yield after multiple steps have restricted the pursuit of complicated giant molecules with high efficiency. Being complementary to organic synthesis, self-assembly provided an alternative route to achieving the giant architectures using weak non-covalent interactions in high efficiency, which is in analog to natural systems such as DNA, peptide, and protein. Among the various interactions, coordination has shown unique advantages in terms of directionality, reversibility and strength. Serving as a bottom-up …
