Enhanced Fluoride Removal In Biosand Filters Using Aluminum Oxide Coated Media And Modified Filter Design, Madison Leigh Rice

USF Tampa Graduate Theses and Dissertations

In 2010, the UN formally stated that access to safe drinking water and sanitation is a human right. Yet, one in three people globally do not have access to safe drinking water. Contaminated drinking water can negatively impact the health of consumers. This is a challenge that disproportionally affects developing regions, where limited access to resources exacerbates the problem. One drinking water contaminant of concern is fluoride. Fluoride is often added in low concentrations to drinking water to enhance consumers’ dental health. However, when water with high concentrations of fluoride is consumed frequently, it can have negative health effects, such …

Targeting The Eskape Pathogens By Botanical And Microbial Approaches, Emily Dilandro

USF Tampa Graduate Theses and Dissertations

There is a vital need to find new clinical treatment options to combat ESKAPE pathogen infections. Nature has thus far been the most fruitful at providing antimicrobial compounds, which have been derived from a plethora of sources. Ranging from plants to microbial communities, these organisms create chemical compounds that are used as defense mechanisms against invasive or encroaching organisms and confer the producers with competitive advantages. In this study, cinnamaldehyde was investigated as a botanical approach to finding active antimicrobial compounds that inhibit the ESKAPE pathogens. Here, we show that all the ESKAPE pathogens are inhibited by cinnamaldehyde concentrations between …

Role Of Serum Amyloid P Component In The Pathogenesis Of Chronic Traumatic Encephalopathy, Brittany Urban

USF Tampa Graduate Theses and Dissertations

Serum amyloid P (SAP) component is a glycoprotein that is a major constituent of human serum. SAP has been recognized to stimulate amyloid fibrillogenesis. One way that SAP can be transported to the brain is by passing through the blood brain barrier (BBB). Traumatic brain injury (TBI) and repeated or severe non-penetrating head injury, can escalate the exposure of the brain to SAP, which in turn can contribute to neurodegeneration. TBI can lead to chronic traumatic encephalopathy (CTE) which is a neuropathological condition that has been found in people who have been exposed to repeated head injuries or impacts. In …

Predictive Validity Of Standards-Based And Curriculum-Embedded Assessments For Predicting Readiness At Kindergarten Entry, Elizabeth Ashton Decamilla

USF Tampa Graduate Theses and Dissertations

As with traditional K-12 educational settings, early childhood assessments have been a primary source of information determining whether early educational experiences have promoted children’s readiness to start school in kindergarten. The level of use of Kindergarten Entry Assessments (KEAs) has become more wide-spread to establish levels of school readiness at kindergarten entry.

This quantitative, correlational study of children in schools that have blended Head Start/Voluntary Prekindergarten funded programs examined the predictive relationships between the independent variables (i.e., VPK Assessments and Teaching Strategies GOLD) and the dependent variable of kindergarten readiness, as measured by the Work Sampling System™ (WSS).

Enhanced Nitrogen, Organic Matter And Color Removal From Landfill Leachate By Biological Treatment Processes With Biochar And Zeolite, Bisheng Gao

USF Tampa Graduate Theses and Dissertations

Leachate percolating through landfills must be collected and properly treated. However, high concentrations of ammonia (NH4+), refractory organic matter [measured as chemical oxygen demand (COD)], water color and heavy metals in leachate interfere biological processes in conventional wastewater treatment plants. Constructed wetlands (CWs) have been used in the past to treat leachate, but their design and performance has not been properly optimized. In particular, low cost adsorbent materials, such as zeolite and biochar, have the potential to adsorb ammonia and organic compounds, respectively. This increases their retention in the wetland and reduces their toxicity to microorganisms and plants in the …

The Effects Of Perceived Motivations And Mental Distress On The Likelihood Of Reporting And Engaging In Self-Protective Measures Among Victims Of Stalking, Daniela Oramas Mora

USF Tampa Graduate Theses and Dissertations

The current study examines how perceived motivations and mental distress affect decision-making among victims of stalking. Although stalking victimization has become relatively common in recent years, with approximately 1 in 6 women reporting to have been victims of stalking at some point in their lives, victims of stalking are unlikely to report to police compared to victims of other violent crimes (NISVS, 2015). Though studies have explored the dynamics of stalking, little is known about the role of the victim’s perception of the offender’s motivation in the victim's decision to report to the police and engage in self-protective measures. The …

USF Tampa Graduate Theses and Dissertations

Presenting a history of slavery that resonates with multiple audiences and serves necessary educational goals, while still creating sufficient appeal to attract visitors and remain sustainable is an enormous task faced by museums in post-colonial spaces across the world. The Museum Kura Hulanda in Curaçao finds itself in an unenviable position of maintaining a vast collection compiled by its founder, navigating the complexities of the 400-year legacy of Dutch involvement in the transatlantic slave trade, and sustaining its position within the local business and tourist economy of Curaçao.

Focusing on the exhibitions at the Museum Kura Hulanda as a site …

Gofundtransitions: Narratives Of Transnormativity And The Limits Of Crowdfunding Livable Futures, Hayden J. Fulton

USF Tampa Graduate Theses and Dissertations

Crowdfunding websites, such as GoFundMe, have provided a new avenue for (some) individuals to fund their healthcare needs. The use of these sites requires individuals to story their medical need, in the hopes of receiving financial assistance. Trans individuals encounter unique challenges within the healthcare system, including providers’ lack of knowledge, a dearth of competent care, and widespread individual and institutional cissexism. Because of the difficulties acquiring competent trans-healthcare compounded with broader inadequacies in our healthcare system, many trans folks and their loved ones turn to crowdfunding platforms to help cover the cost of medical transition. In this thesis I …

Research has demonstrated that the atypical protein kinase C-zeta (PKC-ζ) is a component of many dysregulated pathways in breast and ovarian cancer, including cellular proliferation, survival, and cell cycle upregulation. Breast and ovarian cancers affect women every day and are second and fifth leading cause of cancer death. Women who seek treatments are commonly met with invasive surgeries or chemotherapy. Protein kinase C (PKC) is a family of serine and threonine phosphorylating kinases that have been shown to modulate and transduce signaling cascades that play roles in the development and survival of cancers. Atypical PKC (aPKC), have been heavily suggested …

Instrumentalization Theory: An Analytical Heuristic For A Heightened Social Awareness Of Machine Learning Algorithms In Social Media, Andrew R. Miller

USF Tampa Graduate Theses and Dissertations

New innovations in information management and communication technologies have produced technological assemblages which have radically altered the way people socialize and interact with the world. The most significant and ubiquitous of these technologies is what is colloquially referred to as ‘machine learning.’ Like most, if not all, technologies, machine learning models are neither wholly good nor bad. Their functional ethics are largely determined by the context in which they are employed. However, their ubiquity demands that we develop a heightened social consciousness of the way machine learning simultaneous constrains, manipulates and democratizes social processes. In order to develop better social …

Testing Glutathione-S-Transferase Mu 1 (Gstm1) In Protecting Retinal Pigment Epithelium Cells From Oxidative Stress, Inyoung C. Garner

USF Tampa Graduate Theses and Dissertations

Currently, the most widely available treatment for wet age-related macular degeneration (AMD) involves the intraocular delivery of biopharmaceuticals, such as anti-VEGF therapy. Drawbacks of this treatment includes a short-term efficacy, requiring repeated injections with additional risks, and a limited availability of options for non-responders. Furthermore, there are no treatments available for patients diagnosed with dry-AMD. The drawbacks and limitations of current therapies represent a need for more effective and permanent therapy as the prevalence of the population affected by AMD is growing. Antioxidant gene therapies are one solution to these implications, protecting the cells from oxidative stress which is one …

Elemental Climate Disaster Texts And Queer Ecological Temporality, Laura Mattson

USF Tampa Graduate Theses and Dissertations

This thesis approaches climate disaster texts as an opportunity to challenge constructions of the body, space, and time. Developed from embodied experiential knowledge about hurricanes, my work will explore how climate disasters can teach us to reimagine human-nature relationships. In my two analysis chapters, I use critical textual analysis and autoethnography to challenge particular representations of the human-nature relationship as a binary between nature and culture. By intervening in the nature-culture binary, I theorize queer ecological temporality as an opportunity to reveal and challenge constructions of nature and time. Working at the intersections of queer and ecocritical theory, this thesis …

Algorithms To Profile Driver Behavior From Zero-Permission Embedded Sensors, Bharti Goel

USF Tampa Graduate Theses and Dissertations

In this dissertation, we design algorithms to profile driver behavior from zero-permission sensors embedded in modern smartphones and wearables. These sensors are typically the accelerometer, gyroscope, magnetometer, pressure sensor and a few more than are now available in most modern smartphones and wearables. In order to profile driving behavior, we devised algorithms for detecting distraction while driving due to the use of modern-day smartphones (e.g., calling, texting and reading while driving) in real-time.

To do so, we conduct an experiment with 16 subjects on a realistic driving simulator, where each subject, where each subject carries a smartphone and a wearable …

How Audiovisual Composition Reveals Gendered Limitations And Possibilities In Lady Bird In The Wake Of #Metoo, Chandler Micah Reeder

USF Tampa Graduate Theses and Dissertations

This thesis focuses on the film Lady Bird and the historical coincidence of its release one month after the online movement #MeToo began. By giving frame and sound equal importance in my analysis of the film, rather than opposing these elements, I emphasize audiovisual composition and reveal the mutual dependence within what are considered traditional divisions of theory in cinema. These oppositions relate to control and escape, as they are portrayed through the mother and daughter characters, Marion and Lady Bird, as well as through image and sonic elements. My work demonstrates how the audiovisual composition of the film mediates …

Legitimizing Violence: Functional Similarities Of The Religious And The Secular Violence, Tahir Topal

USF Tampa Graduate Theses and Dissertations

As a consequence of the separation between religion and politics, known as secularism, the discussion about violence has also been divided into two main categories –Religious Violence and Non-Religious Violence– in the modern Western academia. The tendency of the leading scholarly work in the discourse of "religious violence" is that "religion" is inclined to be violent more than secular institutions for several reasons. Therefore, the state's violence, as being secular, steps in to bring peace. And the foundational cause of the theories relies heavily on the essential differences of "religion" and the secular. With counter-arguments, William T. Cavanaugh and Talal …

The Effects Of Socioscientific Issues On Informal Reasoning And The Transference To Controversial Issues In A Social Studies Context, Thomas J. Dolan

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine if informal reasoning skills associated with socioscientific issues (SSI) transferred to controversial issues in a social studies context. The principal researcher developed three controversial issues derived from social studies education to create social studies context issues (SSCI). This acronym has been termed by the principal researcher, as controversial issues in social studies have not been evaluated beyond the social studies classroom. Twenty-one, fifth grade students participated in this three-month study, which featured three specific SSI units (A Need for Speed? – speed limit reduction, Roller Coaster Ban – preventing injuries to children, …

Villains Or Vermin? The Differential Effects Of Discrimination And Dehumanization On Immigrant Cardiovascular Responses, Mona El-Hout

USF Tampa Graduate Theses and Dissertations

Immigration has been pushed to the forefront of a national political debate, and immigrants are commonly portrayed as villains and vermin looking to invade and infest Western nations. These negative portrayals of immigrants may have negative implications for immigrant health outcomes. Among other negative health outcomes, studies have found that immigrant cardiovascular disease rates increase with time spent in the U.S. This phenomenon of decreasing immigrant health with extended U.S. residency has been labeled “the immigrant health paradox”, and discrimination has often been posited as a possible explanatory factor. In addition to discrimination, immigrants are often the targets of dehumanization, …

Isotope-Based Methods For Evaluating Fish Trophic Geographies, Julie L. Vecchio

USF Tampa Graduate Theses and Dissertations

Data on the movement and diets of fish during a variety of life stages are important inputs to fisheries stock assessments and marine ecosystem models. Stable isotopes may provide previously inaccessible information on movement and diet of a variety of managed and forage fish species. Here I used several novel means of interpretation for stable isotope data to infer diets and movements of several important fisheries species over both short (weeks to months) and long (lifetime) timescales. To calculate a constant partitioning offset (CPO) between the δ¹⁵N of muscle and of liver tissue, I conducted a literature search …
