Mass-Spectrometry Based Proteomics Of Age-Related Changes In Murine Microglia, Antwoine Flowers

USF Tampa Graduate Theses and Dissertations

The last century has seen a steady increase in the extension of the average lifespan. This has concomitantly produced higher incidences of age-related chronic degenerative diseases like Alzheimer’s and Parkinson’s diseases. Age is the single greatest risk factor for the development of not just these degenerative conditions but cancer as well. The aged niche undergoes a number of maladaptive changes that allow underlying conditions to present and progress. Exactly which changes, contribute to the progression of which disease is currently an area of intense study. However, these answers often present therapeutic targets for disease prevention. Age is characterized by a …

Back Muscle Endurance As Measure By Ito Test Duration, Ronald Figueredo

USF Tampa Graduate Theses and Dissertations

Lower back pain remains one of the most common problems in public health throughout the industrialized world (Strine and Hootman) (Shiri, Solovieva and K.). The prevalence is about 39-54% annually and 60-65% in a lifetime (Hillman, Wright and Rajaranam) (Leboeuf-Yde, N. and Lauritzen). In the United States, lower back pain is the second most common cause of disability, and is the highest cause of disability among men (Center for Disease Control, 2009). An individual quantitative physical examination to detect muscle deficiencies would be very useful for proper placement of workers in demanding physical jobs where back injuries are common. Trunk …

Analysis Of Antibody-Induced Plasmodium Falciparum Sporozoites Through Scanning Electron Microscopy, Sagorika Bera

USF Tampa Graduate Theses and Dissertations

Malaria is a devastating disease that continues to affect millions of people worldwide every year. Specifically, Plasmodium falciparum is the most common human malaria parasite, particularly in sub-Saharan Africa. P. falciparum causes the most malignant and debilitating symptoms with the highest mortality and complication rates. Even with the worldwide efforts of many researchers and organizations, the road to discovering a vaccine has been difficult and challenging. Due do to the improvements in in vitro liver stage assays as well as rodent models of mammalian malaria, pre-erythrocytic stages of malaria have become a more accessible target for experimental studies.

Using Remote Sensing To Evaluate Wetland Recovery In The Northern Tampa Bay Area Following Reduction In Groundwater Withdrawals, Amor Elder

USF Tampa Graduate Theses and Dissertations

In the past, the Northern Tampa Bay Area (NTBA) wetlands saw severe declines in hydrologic conditions due to excessive groundwater withdrawal rates. Eventually these rates were reduced to allow the wetlands to recover. To monitor this recovery, the Southwest Florida Water Management district (SWFWMD) set up a fieldwork based scoring methodology, called the Wetlands Assessment Procedure (WAP). WAP has been used in many studies of the area since groundwater withdrawal reductions; with many of those studies finding the recovery to be mixed at best. However, these studies were very limited in the number of wetlands they could assess due to …

Abundance And Habitat Preferences Of Introduced Muscovy Ducks (Cairina Moschata), Jacqueline Marie Perry Cahanin

USF Tampa Graduate Theses and Dissertations

Muscovy ducks are native only to Central and South America, Mexico, and parts of southern Texas and are considered invasive in some areas outside of their native range. Although they have been introduced worldwide, they remain largely unstudied. The primary focus of this study was to relate Muscovy duck abundance to habitat characteristics of wetlands in Tampa, Florida. Muscovy abundance was measured using point count methods at 21 wetland sites that occur within an eight km radius of the University of South Florida’s main campus. Habitat features at these sites were assessed using field methods and Geographic Information Systems (GIS) …

Self-Representation Of Women In Eighteenth-Century Europe: Lady Anna Miller And The Grand Tour, Annie Kristina Polzella

USF Tampa Graduate Theses and Dissertations

The Grand Tour is known to scholars as a significant period of travel in which members of English society could immerse themselves in the foreign, while also adhering to established social customs. Scholarship previously regarded the Grand Tour as an intellectual journey for aristocratic Englishmen; however, an incorporation of women into this narrative has introduced many new and important themes that merit further study. Women’s increasing participation in the Grand Tour, which gained in popularity in the eighteenth century, reveals many unique aspects of British society in the period. The integration of women into the Tour is also an indication …

(Age)Ncy In Composition Studies, Alaina Tackitt

USF Tampa Graduate Theses and Dissertations

The number of adult learners entering or returning to institutions of higher education is increasing in general and in relation to the traditional student population, and projections suggest that the trend will continue. As automation and technology impact the labor force, educational access is becoming a national concern and a necessity for more adult learners. Access to higher education impacts minority and economically depressed populations disproportionally and increases the personal and professional success of adult students and the long-term prosperity of their families. Although Composition Studies has a history of recognizing and facilitating student populations as they enter the Academy, …

A Novel Approach To The Discovery Of Natural Products From Actinobacteria, Rahmy Tawfik

USF Tampa Graduate Theses and Dissertations

Actinobacteria, primarily the genus Streptomyces, have led to the development of a number of antibiotics, which result from their secondary metabolites or modified derivatives. Secondary metabolite production can result from competition with neighboring microbes in an effort to disrupt growth, aiding in the competition for vital nutrients in impoverished conditions. Such secondary metabolites have the potential to affect a plethora of cellular functions in target cells, including, cell wall development, protein synthesis, protein function and fatty acid synthesis/metabolism. Due to the pandemic spread of antibiotic resistant bacteria, it is imperative to continue the search for new therapeutic agents …

Impacts Of Tourism Development On Livelihoods In Placencia Village, Belize, Crystal Ann Vitous

USF Tampa Graduate Theses and Dissertations

Placencia Village is one of Belize’s leading “eco-destinations,” due to its sandy-white beaches, coral reefs, and wildlife sanctuaries. While the use of “green washing,” the process of deceptively marketing products, aims or policies as being environmentally friendly, has proven to be effective in attracting consumers who are thought to be environmentally and socially conscious, the exponential growth, coupled with the absence of established policies, represents a significant threat to Belize. This thesis examines the political-ecologic dimensions of rapid tourism expansion in Southern Belize by investigating how the health of the biophysical environment is perceived, what processes are responsible for change, …

Volunteer Tourism: Fulfilling The Needs For God And Medicine In Latin America, Erin Howell

USF Tampa Graduate Theses and Dissertations

This study seeks to understand how short-term medical missions fulfill health needs for their recipients in Honduras, and how in turn, mission participants experience need fulfillment as well. By using the theoretical concept of co-construction of health to see how health needs are or are not met, I conducted a thematic analysis of the Baptist Medical and Dental Mission International (BMDMI) resulting in the following themes: 1.) Mission workers receive fulfillment from their experiences in the mission field. 2.) Mission recipients receive partial fulfillment of needs from the mission. 3). Through a calling, missions are a means to an end. …

Tiered Vs. Traditional Daily Undulating Periodization For Improving Powerlifting Performance In Trained Males, Andres Vargas

USF Tampa Graduate Theses and Dissertations

Daily undulating periodization represents an increasingly popular trend in exercise science with which a traditional model has been established. Tiered daily undulating periodization pairs the DUP approach with a tiered training system which allows volume and intensity to be more evenly distributed throughout a given graining cycle. The concept of tiered daily undulating periodization is a novel form of periodization and has not been investigated. As such, a comparison of traditional and tiered daily undulating periodization has yet to be examined. Therefore, the purpose of this study was to compare the effects of traditional and tiered daily undulating periodization models …

Development Of Tools For Stable Transfection In The Human Filarial Parasite Brugia Malayi Via The Piggybac Transposon System, Johan Chabanon

USF Tampa Graduate Theses and Dissertations

Brugia malayi is one of three species of nematode known to cause lymphatic filariasis (LF) in humans. LF infects over 120 million people, causing debilitating disease. Various global programs have been launched in the past 20 years to eliminate LF. These programs have greatly scaled up the resources and efforts allocated to halting the transmission and reducing disease burden. Only a few drugs are used to treat LF, and resistance is thus a devastating possibility. Research aimed at identifying new drug targets could therefore prove essential in elimination of LF.

Genetic manipulation of B. malayi has been limited to transient …

Occupational Noise Exposure Evaluation Of A Group Of Groundskeepers At A University Campus, Monica Elisa Garcia

USF Tampa Graduate Theses and Dissertations

Every year, twenty-two million workers are exposed to potentially damaging noise at work. Last year, U.S. businesses paid more than $1.5 million in penalties for not protecting workers from noise. (OSHA, 2016). In the United States ten million people have some kind of noise related hearing loss (CDC, 2016) and noise damage to the ear may not be detected until it is great enough to cause hearing impairment.

Grounds keeper’s functions consist of a variety of activities that require the use of powered tools such as mowers, riding mowers, leaf blowers, pressure washers, trimmers/edgers and chainsaws. OSHA has stated that …

Latino Subgroups Political Participation In American Politics: The Other Latinos’ Electoral Behavior, Angelica Maria Leon Velez

USF Tampa Graduate Theses and Dissertations

This thesis explores the impact of Latinidad in Latino political participation, especially in regard to voting behavior. Although Latinos often have been portrayed as a decisive electoral group, the reality is they have not fulfilled the expectations imposed upon them. Therefore, I argue Latinos with different levels of group consciousness will engage differently in politics, which affects the voting statistics of the ethnicity in Censuses, reports and surveys. The use of pan-ethnic terms and the constant stereotypes of Latinos all being “the same,” has caused separation rather than cohesiveness within the minority group, which has resulted in low political engagement. …

Daniel Bryan & The Negotiation Of Kayfabe In Professional Wrestling, Brooks Oglesby

USF Tampa Graduate Theses and Dissertations

This thesis will examine the negotiation of kayfabe within the context of professional wrestling using a 2014 WWE storyline that arose from fan backlash as a primary text. The perceived marginalization of wrestler Daniel Bryan by the fans led to a disconnect between the narratives that were performed in-ring and the counter-narratives produced by the fans, which in turn led to an overtly co-authored narrative between in-ring performers and fans. In addition to studying the television narratives that characterize the “Yes Movement,” in WWE, I will analyze archived social media responses within fan communities on Twitter and Reddit to make …

The Effect Of Clinical Experience On Perceived And Self-Reported Empathy In Novice Speech- Language Pathology Clinicians, Erline Vieira Nakano

USF Tampa Graduate Theses and Dissertations

In the field of medicine, empathic providers have been found to bring numerous benefits to a clinical encounter as they are better able to elicit detailed and thorough case histories, build rapport and therapeutic alliance with patients, and foster greater compliance with treatment recommendations. Despite its multiple benefits, empathy has not been researched systematically within the field of speech-language pathology. In medical training, empathy has been found to decline by the time medical students are introduced to direct patient care. Currently, no information is available regarding the empathy trajectory of novice speech-language pathologists.

The goal of the current project was …

Development Of A Transfection System For The Free-Living Amoeba Naegleria Fowleri Using The Piggybac Vector, Kati Räsänen

USF Tampa Graduate Theses and Dissertations

Naegleria fowleri is a free-living amoeba that causes primary amoebic meningoencephalitis (PAM). In the United States, there are between 0-8 cases of PAM per year, with approximately 98% of cases resulting in death. High case fatality and limited treatment options highlight the need for better understanding of this organism in terms of its biology and pathogenicity. Transfection is a useful tool that allows for the study of gene function, but at present no transfection systems have been established for N. fowleri. This study attempts to establish a transfection system for N. fowleri using the piggyBac vector, with the hope of …

Simulation Studies On Ecg Vector Dipole Extraction In Liquid Medium, Pratheek Michael

USF Tampa Graduate Theses and Dissertations

To circumvent some inherent problems in the conventional ECG, this research reinvestigates an ‘unassisted’ approach which enables ECG measurement without the placement of leads on the body. Employed in this research is a widely accepted assumption that the electrical activity of the heart may be represented, largely, by a 3-D time-varying current dipole (3D-CD). From the PhysioBank database, mECG and fECG data were obtained, and Singular Value Decomposition (SVD) was performed to estimate the time-varying Vector ECG dipole. To determine the sensing matrix responsible for transforming the activity of the 3D-CD into the potential distribution on the surface of the …

Reduction Of Airborne Silica Concentration Using A Novel Sand Coating Technology, Elizabeth Rains Lloyd

USF Tampa Graduate Theses and Dissertations

The health effects of silica and the connection to occupational exposure has been known for years. In March of 2016, the Occupational Safety and Health Administration (OSHA) of the Department of Labor (DOL) published a new standard meant to reduce workers’ exposure to silica. The standard update was set forth to further protect workers; OSHA estimates this revision will prevent more than 600 silica-related deaths each year.

A key feature of the updated OSHA standard emphasizes the use of engineering controls and work practices in certain industries. Material handling of industrial sand is a known cause of silica overexposure in …

A Novel Abi-Domain Protein Controls Virulence Determinant Production In Staphylococcus Aureus, Stephanie Michelle Marroquin

USF Tampa Graduate Theses and Dissertations

A major factor in the success of Staphylococcus aureus as a pathogen is its vast arsenal of virulence determinants and, more importantly, the tight and precisely- timed regulation of these factors. Here we investigate the product of the S. aureus gene, SAUSA300_1984, encoding a putative transmembrane protein. This as yet uncharacterized protein belongs to the Abi (abortive infection) family, which are commonly annotated as CAAX-proteases, and are significantly understudied in prokaryotes. In S. aureus the disruption of SAUSA300_1984 results in a drastic reduction of proteolytic and hemolytic activity, as well as diminished pigmentation. This phenotype appears to be mediated through …

Resistance From Within: Domestic Violence And Rape Crisis Centers That Serve Black/African American Populations, Jessica Marie Pinto

USF Tampa Graduate Theses and Dissertations

This thesis uses feminist critical discourse analysis to find and understand the discourses embedded in the mission statements and program documents of three domestic violence and/or rape crisis centers that primarily serve Black/African American populations in three distinct geographic locations in the United States. Existing literature addresses the discourses present in domestic violence and sexual assault service provision, but no literature addresses the discourses present in the mission statements of domestic violence and rape crisis centers, leaving a considerable gap in the literature. This project uses frameworks of feminist understandings of Foucauldian discursive patriarchal power, intersectionality and material feminism to …

Fatty Acid Biomarker Detection For Breast Cancer Using Differential Mobility Spectrometry With Non-Radioactive Ion Source, James Joseph Alberti

USF Tampa Graduate Theses and Dissertations

Differential Mobility Spectrometry (DMS) using a non-radioactive ion source (NRIS) is investigated as a possible medical diagnostic instrument for near real-time detection of breast cancer biomarkers. In previous clinical studies, concentrations of Linoleic, Palmitic and Stearic fatty acids have been observed at different levels in women with carcinoma breast cancer versus women with benign tumors or healthy women showing no signs of breast cancer. Present diagnostic methods require a biopsy of the suspect tissue and a microscopic lab analysis performed to determine its disease state. This process can take hours or days before the patient and doctor are informed of …
