Alternative Approaches To Protect Sensory Inner Ear Tissue Against Cisplatin-Induced Ototoxicity, Nicole K. Febles

USF Tampa Graduate Theses and Dissertations

Sensorineural hearing loss (SNHL) is a prevalent neurodegenerative disorder often involving permanent damage and loss to the inner ear’s mechano-sensory hair cells and spiral ganglion neuron fibers. Significant causes of SNHL are ototoxic drugs, environmental factors, loud noises, and continuous wear with age. A successful but ototoxic chemotherapeutic known as Cisplatin often damages auditory hair cells via mitochondria dysfunction, DNA fragmentation, and cellular death through apoptosis. Despite the high prevalence of SNHL, there currently is no FDA-approved prevention or cure. Thus, auditory and cancer researchers have investigated various individual otoprotective agent preventions with limited success. This dissertation used a novel …

How Culture And Storytelling Can Influence Urban Development: An Ethnographic Look At The Community-Driven Revitalization Of Newtown In Sarasota, Florida, Michala Head

USF Tampa Graduate Theses and Dissertations

When Americans think of Florida, tourist attractions often trail the initial thoughts of alligator sand chaos. Disneyworld and its neighboring parks are set up for optimal experience and consumption, the thought of a trip South along the coast for a sweltering beach day, sipping on a frozen drink in January sings to Midwesterners. For residents of these seaside cities, such as Sarasota, the experiences of the space are much more complex. Within the broader contexts of the resurgence of the Black Lives Matter movement following the murder of George Floyd and a global pandemic that impacted America’s marginalized populations disproportionally, …

Data-Driven Studies On Social Networks: Privacy And Simulation, Yasanka Sameera Horawalavithana

USF Tampa Graduate Theses and Dissertations

Social media datasets are fundamental to understanding a variety of phenomena, such as epidemics, adoption of behavior, crowd management, and political uprisings. At the same time, many such datasets capturing computer-mediated social interactions are recorded nowadays by individual researchers or by organizations. However, while the need for real social graphs and the supply of such datasets are well established, the flow of data from data owners to researchers is significantly hampered by privacy risks: even when humans’ identities are removed, or data is anonymized to some extent, studies have proven repeatedly that re-identifying anonymized user identities (i.e., de-anonymization) is doable …

A Review Of Marine Turtle Orientation And Artificial Lighting Impacts With Novel Results From Florida’S Gulf Coast, Andrea M. Fisher

USF Tampa Graduate Theses and Dissertations

Artificial light (i.e. unnatural light emitting from a human-made source) is one of the most extensively distributed, and least managed, type of anthropogenic pollution. Due to the disproportionally high rates of urbanization in critical coastal ecosystems, species, like marine turtles that use beach habitat for nesting activities, are especially vulnerable. Marine turtles employ the use of multiple visual cues (e.g. wavelength, intensity, background illumination, and dark silhouettes) to conduct sea-finding behavior and different variations in cue usage exist across species and geographic location. During nesting and emergence activities, orientation can be interrupted and manipulated by artificial lighting resulting in lower …

This study was conducted to investigate predictors of physical and mental health quality of life in aging adults who stutter (AWS). Our goal was to identify factors contributing to successful aging in this talker group. The aging population is expected to increase exponentially over the next twenty years. Factors influencing self-perceived health-related quality of life have yet to be investigated in aging AWS.

An online survey was completed by a total of 40 AWS, age 50 years and older, recruited from the Greater Tampa Bay region and nationally. The survey comprised multiple measures that probed for information regarding self-perceived health …

Native And Non-Native English-Speaking Doctoral Students' Strategies To Understand Idiomatics In Comics And Comic Strips, Himelhoch Luz-Aydé

USF Tampa Graduate Theses and Dissertations

Everyday language consists of many idiomatic and figurative expressions. For non-native English speakers to achieve native fluency, control of idiomatics—native speech that includes the use of both idiomatic and figurative language—is paramount. In this study, I aimed to explore the use of comics and comic strips in the learning and comprehension of L2 (second language) idiomatics. Seldom has the topic of comics and comic strips been addressed as it applies to idiomatics learning in second language acquisition (SLA). I employed a descriptive and exploratory approach in this study to address this gap in SLA pedagogy. A total of 21 doctoral …

The Extended Parallel Processing Model (Eppm) And Risk Perceptions Of Twitter Messages Related To Covid-19, Muhammad E. Rasul

USF Tampa Graduate Theses and Dissertations

Since its genesis, the novel coronavirus or COVID-19 has claimed millions of lives across the world and has infected many more. The population in the US experienced one of the worst outbreaks of COVID-19 in the world, with the number of deaths rising monolithically at one point. Although the development and inoculation of a large number of the public has helped, newer variants threaten to revitalize the growth and spread of COVID-19. Scholars have extensively studied health messages related to COVID-19 in a variety of contexts. However, little attention has been paid to the risk perceptions of health messages related …

Career Development And Workforce Experiences Of Trans People In Their Workplaces, Rene Ragmett Alvarez

USF Tampa Graduate Theses and Dissertations

Existing research concerning trans people is sparse, and even less research exists regarding their career development and workforce experiences. Hence, I explored the career development and workforce experience stories of trans people. I used a conceptual and theoretical framework in this study to inform my general approach to trans scholarship leading to the specific examination of the career development and workforce experiences of trans persons. The conceptual and theoretical framework included Hale's (1997) suggested guidelines for non-trans people writing about trans people, constructivism, social cognitive career theory, and minority stress theory and informed the qualitative vehicle of this study to …

“Here Come The Crackers!”: An Ethnohistorical Case Study Of Local Heritage Discourses And Cultural Reproduction At A Florida Living History Museum, Blair Bordelon

USF Tampa Graduate Theses and Dissertations

This project explores the complex roles of power and heritage in the reproduction ofcultural and ethnic identities in the context of a local living history museum called Cracker Country. Throughout this thesis, I demonstrate how discourses of Florida heritage are constructed, reproduced, or contested in various ways among all the museum’s different communities of stakeholders. Using Michel-Rolph Trouillot’s (1995) theory of historical silences and expanding on Laurajane Smith’s (2006) notion of the Authorized Heritage Discourse, I explore the ways that heritage “works” at a local level, and the multitude of meanings it can hold within particular communities. I analyze the …

Influence Of Coating Defects Within The Lock Seams On The Corrosion Performance Of Aluminized Steel Drainage Pipes, Mohammed Al Yaarubi

USF Tampa Graduate Theses and Dissertations

The electrochemical behavior of aluminized steel is investigated to determine the corrosion performance of coating deficiencies generated within the lock seams during the fabrication of aluminized steel corrugated pipe. Electrochemical techniques and visual and profilometric analysis are used to assess the ability of the aluminum and zinc coating to provide sufficient galvanic protection to the underlying steel in the presence of a crevice. Also, Crevice coupons and lock-seam samples were used in this investigation in different environmental conditions simulating natural water conditions to relate the corrosion rate with the level of protection that the coating will provide. In addition, a …

Metabolic Rate, Critical Oxygen Partial Pressure, And Oxygen Supply Capacity Of Farfantepenaeus Duorarum At Their Lower Thermal Limit, Alexandra L. Burns

USF Tampa Graduate Theses and Dissertations

Temperature and environmental oxygen availability affect oxygen supply and demand in ectotherms, which are hypothesized to control the geographic limits of many marine species. The oxygen supply capacity (α) is calculated from commonly measured metabolic traits, including the standard metabolic rate (SMR) and critical oxygen partial pressure at SMR (Pcrit). It may be used to estimate the metabolic capacity and aerobic scope across changes in temperature and oxygen partial pressures as α reflects adaptations of the cardiorespiratory system to meet maximum energy demands at a given oxygen partial pressure (PO2). In this study, α was measured for the Tampa Bay …

"We're The Lucky Ones": A Social Network Analysis Of Recovery After The Iowa Derecho, Kayla C. Jones

USF Tampa Graduate Theses and Dissertations

On the afternoon of August 10th, 2020 a straight line windstorm, referred to as a derecho, tore across the Midwest. Derechos are often described as an “inland hurricane,” with wind gusts exceeding 58 mph. This thesis explores how Iowans relied on social networks to recover from the derecho. Personal networks were analyzed to understand how people utilized relationships for specific types of support. The relationships investigated included informal and formal sources such as family, friends, neighbors, government, volunteers, non-governmental organizations, and self-reliance. Data were collected on social networks and storm recovery through a survey and semi-structured interviews. Using anthropological theories …

Development Of A Numerical Process Model For Adsorbent-Amended Constructed Wetlands, Lillian Mulligan

USF Tampa Graduate Theses and Dissertations

There is a need for alternative methods for municipal landfill leachate treatment as the high concentrations of pollutants in leachate interfere with processes at publicly owned treatment works (POTWs). Constructed wetlands (CWs) have been shown to be a sustainable alternative with good removal efficiencies for chemical oxygen demand (COD) and ammonia nitrogen (NH4+). The addition of an adsorbent media, such as zeolite and biochar, to CWs to further enhance removal efficiencies has been investigated in recent years. However, the long-term effects of zeolite and biochar addition to CWs is not well known. A model could be a useful tool to …

Transparent Planar Micro-Electrode Array For In-Vitro Electric Field Mediated Gene Delivery, Raj Himatlal Shah

USF Tampa Graduate Theses and Dissertations

Gene delivery is the process of delivering the modified gene into the human cell. There are two types of gene delivery depending on where the target cells are. The in-vivo gene delivery deals with delivering the altered genes into the cells while still in the host body. While another approach is to extract the cells from the host body, transfer the modified gene into cells and then put these cells back into the host body, this approach is called the ex-vivo method.

A vector is a carrier that carries the modified gene to the host cell or body. Hence, depending …

Presenting Selves And Interpreting Culture: An Ethnography Of Chinese International Tourism In The United States, Fangheyue Ma

USF Tampa Graduate Theses and Dissertations

I situate my dissertation research within cultural sociology, specifically the cultural phenomenon of international tourism, and social psychology, particularly the subfields of identity, interaction, and emotion. I conducted a qualitative study of participants in international package tourism and individual travelers, more specifically, Chinese tourists who travel to the United States. Main topics of exploration included tourists’ experience of their trips and package tours, how they interpreted American culture and compared it to their own, how they constructed and performed identities both as tourists and as Chinese nationals, their emotional experiences and how they made sense of an environment that they …

A New Age Of Telehealth: Pediatric Speech-Language Pathology Services During The Covid-19 Pandemic And Beyond, Deborah R. Campbell

USF Tampa Graduate Theses and Dissertations

The COVID-19 pandemic potentially changed the landscape of how speech-language pathologists provide services. Prior to March 2020, pediatric speech-language therapy provided via telehealth was limited; however, the COVID-19 pandemic caused a worldwide conversion from in-person care to a remote service delivery model. This conversion brought to the fore possible benefits and utility of telehealth use. Yet, clinicians potentially experienced barriers to its use, including the lack of validity and reliability evidence for remote administration of several pediatric assessments. For the viability of remotely delivered speech-language services to continue and evolve in a post-pandemic world, further research is needed to identify …

USF Tampa Graduate Theses and Dissertations

The purpose of this evaluation was to investigate the factors that contribute to students’ recruitment and retention in the Arabic program at my college. The two questions guiding this evaluation were: (1) what factors influence students to join the Arabic program at my college and (2) what factors influence students to continue to enroll in subsequent higher-level Arabic courses? To accomplish this evaluation, I conducted interviews with six former students --four women and two men--in the Arabic program. Eight themes emerged following analysis of data. The findings show that students joined the Arabic program for a variety of reasons. Several …

Cytoplasmic Polyadenylation Element Binding Protein 2 Alternative Splicing Regulates Hif1Α During Chronic Hypoxia, Emily M. Mayo

USF Tampa Graduate Theses and Dissertations

Chronic pulmonary hypoxia commonly results in the sustained expression of HIF1 (hypoxia inducible factor 1), a heterodimeric transcription factor, that, if unrestrained, can result in dramatic vasculature remodeling, pulmonary arterial hypertension, and right-sided heart failure. Together, these pulmonary disorders cost approximately $100 billion annually to treat due to the limited therapeutic targets designed to inhibit HIF1 expression. In this study, we introduce a translational regulator of HIF1 expression, known as Cytosolic polyadenylation element binding proteins 2 (CPEB2). Our lab has previously demonstrated in cancer cells that alternatively spliced isoforms of CPEB2 regulate the translation of the HIF1 oxygen-dependent subunit, HIF1α, …

Mitigating Negativity Bias In Media Selection, Gabrielle R. Jarmoszko

USF Tampa Graduate Theses and Dissertations

A growing body of research explores implicit negativity bias and how it influences news selection processes of media consumers. However, very little, if any, research exists exploring how negativity bias in the news selection process can be mitigated. Informed by experimental designs that have proven effective in mitigating other types of implicit bias, this study aimed to investigate whether having consumers commit themselves to definitions of their preferred type of news before engaging in the selection process alters manifestations of negativity bias in the selection. This study tested two hypotheses: H1, that non-committed individuals will have a higher selection frequency …

Feasibility Of A Virtual Group Nutrition Intervention For Adolescents With Autism Spectrum Disorder, Acadia W. Buro

USF Tampa Graduate Theses and Dissertations

Background: Youth with autism spectrum disorder (ASD) have an increased likelihood of being overweight or developing obesity. As children and adolescents with ASD exhibit problematic eating behaviors and may consume more energy-dense foods and fewer fruits and vegetables than typically developing youth, nutrition represents a modifiable obesity risk factor for adolescents with ASD, yet there is a lack of interventions to improve healthy eating and reduce the risk of obesity in this population.

Purpose: The purpose of this study was to examine the feasibility, acceptability, and preliminary efficacy of a virtual implementation of BALANCE (Bringing Adolescent Learners with Autism Nutrition …

“Be Valiente”: Investigating Ethnic Identity Through Digital Storytelling With Latinx Fourth-Grade Students, Jennifer Michelle Barreto

USF Tampa Graduate Theses and Dissertations

Multilingual and multicultural students face the challenge of understanding where their ethnic identity lies in learning. The education system in the United States lacks inclusivity in classrooms, continuing monocultural views and monolinguist ideals as the norm and encouraged in curriculum and standards (Flores, 2020). This dissertation study seeks to break cultural and linguistic ideologies to better understand the development of ethnic identity in three Latinx fourth-grade students by creating a digital story. Through a sociocultural lens that includes a bioecological model (Bronfenbrenner, 1977; Vélez-Agosto et al., 2017) and multimodality (NGL, 1996) framework the study emphasizes all funds of knowledge (Moll …

Montage Music Videos: Racial Utopianism Vs. Abstract Cowboys And The Question Of Cultural Montage, Alan E. Blanchard

USF Tampa Graduate Theses and Dissertations

Along with the explosion of consumer goods in America over the past century came the human impulse to alter these objects to produce new meanings the manufacturers never intended: commercial products become amateur artists’ raw material. We see this with custom cars and the curious blending of clothes. Inevitably, digital commercial products, like music videos, would undergo a similar treatment as seen in DJ Cummerbund’s “mashup” videos “Old Staind Road” and “Blurry in the USA” where he is painting with audio tracks and sculpting with video clips to create new digital art with new meanings uncoupled from industry’s original intent …

Low-Cost Device For Laser Phacoemulsification: A Preliminary Study, Mitchell Harrah

USF Tampa Graduate Theses and Dissertations

The current gold standard of cataract removal surgery is phacoemulsification systems. These are divided based on the type of devices used; both are considered equal but with different delivery modes. These delivery methods are either acoustic or light-based. However, these devices pose two hurdles for impoverished areas: high costs and heavy resource usage. This thesis proposes a novel phacoemulsification system is based on the low-cost, off-shelf laser diodes that implement light-based phacoemulsification of cataracts. The system is tested for viability over two methods: finite element analysis and experimentation on various phantoms. Simulations on the device have occurred on the COMSOL …

Making A Home Away From Home: A Qualitative Study Of African Students’ Practices Of Integration In The United States, Alphonse O. Opoku

USF Tampa Graduate Theses and Dissertations

Over the last two decades, the population of international students in the world has significantly increased. More and more students from diverse backgrounds cross national borders to study. The observed increase in numbers and diversity has led to an uptick in scholarly research that focuses on the adaptation and experiences of international students. Most of these studies, particularly in the US, are informed by the acculturation theories and assimilationist frameworks of the 1900s. Also, an exclusive focus is placed on the host country, with few studies acknowledging the impact of the origin country on the international student experience. Such approaches …

Green Business And The Culture Of Capitalism: Constructing Narratives Of Environmentalism, Julia S. Jester

USF Tampa Graduate Theses and Dissertations

There are widespread colloquial arguments claiming that any actions taken to combat climate change will be bad for business and the economy, scaring people into continuing their support for the status quo for fear of their financial security. Alternatively, those attempting to combat ecological destruction have subsequently made transitions to sustainable development of products and shifting consumer behavior within this system. There is one core argument that both sides have, albeit in different ways – capitalism and environmentalism are seemingly incompatible; one cannot be successful without the eradication of the other. While it may appear there are only strict binary …

A Longitudinal Examination Of Coping And Subjective Well-Being Among High School Students In Accelerated Curricula, Hannah L. Gilfix

USF Tampa Graduate Theses and Dissertations

High school students in accelerated curriculum, which include Advanced Placement (AP) and International Baccalaureate (IB) programs, face greater amounts of academic stress than those in the general education curriculum (Suldo & Shaunessey, 2013). It is crucial to understand how these students cope with their academic demands and the impact that their use of various coping factors has on their overall subjective well-being. This study utilized a longitudinal non-experimental design to a) examine the stability of coping factors, b) examine the relationship between individual coping factors and subjective well-being, c) investigate the impact of socioeconomic status on the relationship of coping …

The Role Of Antecedent Music In The Running Routines Of Experienced Runners, Jennifer L. Cook

USF Tampa Graduate Theses and Dissertations

Promoting running as an accessible and cost-effective form of exercise is important because persistent runners have a 29 to 50% lower risk of cardiovascular mortality compared to those who never run (Lee et al., 2014). Although there is a body of research on music and running, the results have been inconclusive across the literature. This may be due to a reliance on self-report measures and the averaging of results employed with group designs. To address these issues, the current study measured performance (pace) as the primary dependent variable in a series of within-subject designs. First, an online cross-sectional survey (Study …

The Ring Of Gyges 2.0: How Anonymity Providing Behaviors Affect Willingness To Participate In Online Deviance, Cassandra E. Dodge

USF Tampa Graduate Theses and Dissertations

Anonymity has long been discussed as a source of disinhibition. The myth of the Ring of Gyges illustrates how a person may act immorally solely because they know they will not be caught (Plato, 375/2017). Incorporating perspectives of rational choice and deterrence, anonymity serves as a form of risk reduction within hedonistic calculus (Beccaria, 1764/1963; Bentham, 1781/2000). Analogous to the myth of the Ring of Gyges (Plato, 375/2017), techniques of anonymity “hide” users from others while online. These techniques serve as a form of risk reduction, reducing the certainty of punishment (Becarria 1764/1963). Additionally, there are many ways by which …
