USF Tampa Graduate Theses and Dissertations

Over the past few years, smart textiles and wearable technologies have received tremendous attention due to their functionalities and characteristics, which could be used in a variety of ways in healthcare, sports/leisure, fashion, military, personal protective, and energy applications. These technologies depend on self-power systems, which require energy sources (e.g., batteries, supercapacitors, and solar cells) to power their projected functionalities in the future. Therefore, fabricating energy harvesting cells (i.e., solar cells) and energy storage cells (i.e., batteries and supercapacitors) in the form of fibers are promising solutions for powering wearable electronics due to their unique features such as flexibility and …

Why Don’T They Just Ask?: Barriers To Directly Requesting Affirmative Sexual Consent By Gender And Sexual Orientation, Jessica A. Jordan

USF Tampa Graduate Theses and Dissertations

Most young adults report a discomfort with verbally and explicitly asking for sexual consent from a partner. Social scientists have theorized this discomfort is driven by conformity to rigid gender roles, sexual scripts, and peer norms, although little research has directly examined the relationship between these barriers and consent behaviors. Most consent research has focused on heterosexual individuals, and even fewer studies have compared the sexual consent attitudes and behaviors of heterosexual and sexual minority individuals. Through a series of three studies, I examined the reasons heterosexual and sexual minority young adults hesitate to ask a new partner for sexual …

Distributed Leadership: Formal Leadership, Barriers, And Facilitators For Multi-Tiered Systems Of Support, Joseph D. Latimer

USF Tampa Graduate Theses and Dissertations

Currently, educators are exposed to an increased environment of accountability, which prioritizes student academic achievement. That environment of accountability is reinforced by multiple pieces of legislation that also call attention to the implementation of multi-tiered systems of support (MTSS). Even with these federal mandates, educators are continuously overwhelmed implementing MTSS and often leverage distributed leadership practices such as school leadership teams to carry out school improvement tasks. Both distributed leadership practices and MTSS are directly impacted by the practices of formal leadership (i.e., principals). In addition, enablers of and barriers to distributed leadership for MTSS should be investigated. This current …

A Physically Constrained Wavelet-Aided Statistical Model (Pcwasm) For Multidecadal Groundwater Dynamics Predictions And Climate Change Evaluation, Fatih Gordu

USF Tampa Graduate Theses and Dissertations

Long-term groundwater management relies on forecasts of decadal or longer groundwater levels driven by nested scales of variability in climate. Discerning the impacts of anthropogenic stressors on groundwater is also critical for establishing predevelopment benchmark groundwater conditions and developing climate change adaptation strategies to reduce risks and increase resiliency. This research demonstrates the development and successful applications of a new methodology to predict and assess multidecadal groundwater dynamics for understanding long-term effects of climate change and groundwater withdrawals.

A Physically Constrained Wavelet-Aided Statistical Model (PCWASM) is first introduced to analyze and predict monthly aquifer levels on multidecadal time scales. The …

The Labors Of Professional Wrestling: The Dream, The Drive, And Debility, Brooks Oglesby

USF Tampa Graduate Theses and Dissertations

This study centers and examines the laboring body of the professional wrestler as it moves and works through professional wrestling training. I put forth debility as a theoretical framework to naming and understanding the ways that long-term bodily wear and early death becomes an acceptable cost of doing business for the wrestling industry. Dreams of achieving wealth, fame, and stability while escaping precarity and obscurity draw fans toward joining the industry, and these dreams work to maintain a working culture that takes for granted the ways that the wrestler’s body is marked for disposability, wearing down, and early death. I …

Essays On Upper Echelons Research In Sales Management, Hao Wang

USF Tampa Graduate Theses and Dissertations

This dissertation investigates the role of sales executives in top management teams (TMTs) in driving firm performance. Chapter I offers an overview of the dissertation. Chapter II (“The double-edged sword of sales force power in top management teams”) investigates the impact of salesforce power (i.e., the sales department’s influence in TMT) on organizational performance. The study examines two internal factors (i.e., marketing department power and sales growth) and two environmental factors (i.e., competitive dynamics and market size) that may either weaken or strengthen the influence of salesforce power on organizational performance. Using a panel data set of 10,751 firm-years observations …

An Internet Of Medical Things (Iomt) Approach For Remote Assessment Of Head And Neck Cancer Patients, Ruchitha Chinthala

USF Tampa Graduate Theses and Dissertations

Internet-of-Medical-Things (IoMT) allows for a smart healthcare system to remotely monitor and assess patient’s progress at home. Head and neck cancers (HNC) are treated with various treatment options which are associated with significant side effects, mainly shoulder dysfunction, and trismus (spasm of jaw muscles). However, measurement of patient’s progress, and side effects while undergoing treatment, is limited to evaluation received based on scheduled appointments. Development of strategies to enhance monitoring during follow-up period is needed for earlier identification of problems such as trismus and shoulder dysfunction. In this interdisciplinary research, for the first time, we develop an IoMT enabling application, …

Characterizing Explosive Volcanic Eruptions Using Tephra Fall Deposit Data, Robert Constantinescu

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the estimation of the magnitudes and intensities of explosive volcanic eruptions using tephra fall deposits and numerical modeling. Tephra fall deposits retain information about eruption dynamics. Volcanologists sample tephra fall deposits and measure the thickness, extent and grain size distribution to estimate the erupted volume and plume height of explosive eruptions. These terms are known as eruption source parameters. These parameters are used to classify the intensity and magnitude of the eruption on a scale such as the Volcanic Explosivity Index (VEI). Accurate estimation of the intensity and magnitude of explosive eruptions is a crucial factor in …

Assessment Of Scoured Bridges Subjected To Vessel Impact Using Nonlinear Dynamic Analysis, Amir S. Irhayyim

USF Tampa Graduate Theses and Dissertations

Scour has been the number one cause of bridge failure in the United States with an average of 22 bridges collapsing or being closed owing to severe deformation each year [1]. This work attempts to deal with two important issues: (1) Potential bridge failures during the co-occurrence of scour and ship impact; (2) Incorporating IDA analysis to predict bridge responses based on barge and collision parameters, and to generate fragility curves to predict the probability of exceedance damage states.

For bridges, flooding is considered the most threatening hazard. According to the National Bridge Inventory (NBI) [2], 500,000 out of 615,000 …

A Macro Social Examination Of The Relationship Between Disabilities And Crime Using Neighborhood And County Level Data, Natasha A. Baloch

USF Tampa Graduate Theses and Dissertations

Over the last few decades, there has been a consistent increase in mental illnesses in the US population. This has also lead to increased interactions of those with mental illnesses and/or disabilities with law enforcement and the criminal justice system. Despite these instances, there is limited research on the relationship between disabilities, mental health issues and crime in the large body of criminological research. Further, the current extant research is a) outside the field of Criminology, b) primarily focuses on those with only intellectual or developmental disabilities and/or c) does not examine this relationship at the macro level, despite evidence …

Analyzing Decision-Making In Robot Soccer For Attacking Behaviors, Justin Rodney

USF Tampa Graduate Theses and Dissertations

In robotics soccer, decision-making is critical to the performance of a team’s SoftwareSystem. The University of South Florida’s (USF) RoboBulls team implements behavior for the robots by using traditional methods such as analytical geometry to path plan and determine whether an action should be taken. In recent works, Machine Learning (ML) and Reinforcement Learning (RL) techniques have been used to calculate the probability of success for a pass or goal, and even train models for performing low-level skills such as traveling towards a ball and shooting it towards the goal[1, 2]. Open-source frameworks have been created for training Reinforcement Learning …

Watershed Management For Nutrient Control In Taylor Creek And Nubbins Slough, Florida, Rachael Z. Cooper

USF Tampa Graduate Theses and Dissertations

Despite efforts to improve water quality within the watershed since the 1970s, harmful algal blooms (HABs) still occur within Lake Okeechobee (LO). HABs are harmful to the people, the ecosystem, and the economy dependent on the lake. Taylor Creek Nubbins Slough (TCNS) is a subwatershed of the lake, contributing to a large percentage of the nutrient loading. Due to the size and complexity of LO’s watershed, two smaller basins within the TCNS subwatershed were selected to evaluate the following research questions: (1) How do water quality trends contrast between two basins? (2) How do nutrient load and treatment within the …

Testing The Protest Paradigm And Racial Threat: Analyzing Articles Of Blm Protests In 2014 And 2020, Rebecca Angela Ruiz

USF Tampa Graduate Theses and Dissertations

The study examines the media coverage of Black Lives Matter protest in years 2014 & 2020. I collected a sample of articles (n=120) from 6 national-level media outlets that varied in political leans. Using the Protest Paradigm and Racial Threat theoretical frameworks to analyze the results, findings suggest that the articles do reflect upon the Protest Paradigm through overall negative sentiment and significant references to looting. I also argue that articles may also reflect racial threat due to a lack of transparency of protesters’ racial makeup or diversity attending demonstrations.

_Las Vidas Negras_: Examining Identity Among Afro-Latinos In The Us In The Twilight Of Black Lives Matter, Victor Garcia

USF Tampa Graduate Theses and Dissertations

This work seeks to name how the Black Lives Matter movement, and related movements for Black liberation and justice, has had an effect on the self-perception and identities of US-based Afrolatinos. Using survey and interview data, I tease out issues of ethnoracial dissonance, social identity, and the ways that Afrolatinos have used the context of Black Lives Matter to make sense of the antiblackness they have faced. This is a significant investigation because it speaks to the potential for a richer tradition of pan-Africanism taking root in Latin America and among Latin Americans of African descent.

Estimating The As-Placed Grout Volume Of Auger Cast Piles, Tristen Mee

USF Tampa Graduate Theses and Dissertations

Augered Cast-in-Place (ACIP) piles are a geotechnical foundation element increasingly used to support large publicly funded structures as an alternative to drilled shafts or driven piles. ACIP piles are constructed by drilling an excavation to the full length of the designed pile with a continuous flight auger. Grout (cement, sand, and water mixture) is then pumped through the hollow auger stem to begin grouting the excavation. After establishing an initial head pressure, the auger is slowly extracted while the remainder of the pile is grouted. Once the auger is completely removed, the steel reinforcement cage is lowered into the grouted …

The European Super League (Esl): A Political Economy And Media Framing Analysis, Patrick Sidwell

USF Tampa Graduate Theses and Dissertations

The European Super League (ESL) offers an opportunity for research as a case study which exemplifies the potential for sports to engender seismic societal events. To try to understand the ESL and the events surrounding it, this thesis examined it through the dual frameworks of political economy and framing theory to comprehend the roles played by corporate owners and working-class fans who support the game. An overview of the political economic processes of English football was conducted to create meaningful insights. From there, using framing as a theoretical guide, a thematic media analysis was performed across 251 news articles from …

Visions Of Entanglement And Escape: In-Visible Voice In The Films Of Terrence Malick And George Lucas, Michael Lee Taber

USF Tampa Graduate Theses and Dissertations

This thesis juxtaposes the unexpectedly parallel careers of the filmmakers George Lucas and Terrence Malick. Both popularly and academically, Lucas and Malick are typically conceived as divergent practitioners and are framed in oppositional terms. The goal of this thesis is – in part – to break down this oppositional understanding of Lucas and Malick as filmmakers. This traditional understanding of Malick and Lucas collapses when we consider their respective relationships to sensation and abstraction. Affirmations of sensation and Malick abound, as do critiques of abstraction and Lucas – all the while it is Malick who is aligned with abstraction and …

Evaluating And Improving A Novel Toolkit For Implementation And Optimization Of Lynch Syndrome Universal Tumor Screening, Tara M. Wolfinger

USF Tampa Graduate Theses and Dissertations

Individuals with Lynch syndrome (LS) have a hereditary predisposition to colorectal cancer (CRC), endometrial cancer (EC), and several additional cancer types. Universal tumor screening (UTS) is a systematic approach that increases identification of LS so affected individuals can benefit from targeted therapies and risk-reduction strategies to decrease cancer- related morbidity and mortality. Despite the known benefits of UTS, the practice is widely underutilized, likely due to the complexity of implementation and optimization. We developed a novel evidence-based toolkit to help institutions implement and optimize UTS programs. As part of an iterative evaluation process, we obtained feedback on the toolkit through …

Carbon Diversion, Partial Nitritation/Anammox Enrichment, And Ammonium Capture As Initial Stages For Mainstream Ion Exchange-Deammonification Process, Sheyla Chero-Osorio

USF Tampa Graduate Theses and Dissertations

Eutrophication is a concerning environmental problem worldwide that results in algae blooms, oxygen depletion, damages to aquatic life and public health, water quality issues, and loss of aesthetics in water reservoirs. Nutrient (e.g., nitrogen and phosphorus) discharges from wastewater, agricultural, urban, and residential runoff promote eutrophication in receiving water bodies. In terms of nitrogen removal, conventional biological nitrogen removal (BNR) is a common technique used in many wastewater treatment plants (WWTP). However, BNR requires aeration for nitrification and organic carbon input for denitrification. In WWTP, the aeration represents a considerable investment in terms of energy costs. Recent technologies involve applying …

Stitched Together: What We Learn From Secret Stories In Public Media, Sara D. Rocks

USF Tampa Graduate Theses and Dissertations

Where do you go to divulge your deepest secrets? Some may turn to journals and diaries; some turn to family and friends; some turn to religious confessionals; some turn to Twitter; and still, some take their secrets to the grave. There is at least one other way people share their secrets that has thus far received limited scholarly attention: the crowdsourced confessional. In the new media landscape, intimate stories and personal disclosures with strangers can be (and are) produced as content for a vast pool of additional strangers to consume as media. Yet, little is known about the personal narratives …

Racial Differences In Perceptions Of Sanction Severity, Sarah L. Franklin

USF Tampa Graduate Theses and Dissertations

Research has consistently found an association between race and relative perceptions of incarceration severity. Black people view incarceration as less severe than an equivalent period of probation. However, few studies have examined why this relationship exists. The present study surveys a large sample of young adults to examine whether the observed relationship between race and incarceration severity can be replicated. In doing so, the study then considers whether constructs related to socioeconomic status, criminal system experiences, perceptions of legitimacy, and sanction attitudes explain the racial divide. Results indicate a significant relationship between race and incarceration severity, such that Black people, …

The Impact Of Self-Monitoring Using I-Connect For Increasing On-Task Behavior For Students With Or At Risk Of An Emotional Behavioral Disorder, Marissa Lenae Del Vecchio

USF Tampa Graduate Theses and Dissertations

The use of technology-based self-monitoring interventions is becoming more popular, increasing the likelihood that self-monitoring interventions will have greater contextual fit within classrooms. Self-monitoring has resulted in increases in desired school behaviors, such as increases in on-task behavior, academic performance and task completion, for students diagnosed with disabilities. The purpose of this study was to extend the findings from Clemons et al. (2016) and examine student and teacher use of a web-based self-monitoring application, I-Connect, and reinforcement to increase on-task behavior for upper-level elementary school students with or at risk for an emotional behavioral disorder (EBD) using extended self-monitoring intervals. …

Bayesian Network-Based Diagnostic Support Tool With Limited Point-Of-Care Ultrasound For Work-Related Elbow Injuries, Cristina Maria Franceschini Sánchez

USF Tampa Graduate Theses and Dissertations

The upper extremity is commonly injured at the workplace, frequently involving the elbow. Currently, there are not many diagnostic support tools for elbow injuries. Developing a clinical decision support tool would allow for narrowing differential diagnoses and guide management steps in a timely and cost-effective manner. In a descriptive retrospective cohort study, 85 non-contrast elbow MRIs were obtained from a large Workers Compensation insurer database. MRIs were either (a) greater than 2 weeks after first clinic visit, or (b) more than 6 weeks after injury, but (c) not more than 3 months after injury. A Bayesian network-based diagnostic support tool …

Pronk Poppenhuis: Establishing And Destabilizing Agency Among Seventeenth-Century Burgher Wives In The Dutch Republic, Emily M. Gregoire

USF Tampa Graduate Theses and Dissertations

This thesis shines novel light on the Dutch pronk poppenhuis, as a microcosm which models the simultaneously destabilization and establishment of agency among the Baroque burgher wives who commissioned them. Closely discussing seventeenth-century Dutch female ambitions, this article will explore the ways in which these housewives were both taught to behave appropriately in Dutch society and how they then displayed obedience to those values. I concurrently argue that the commissioning of and interaction with the pronk poppenhuis, particularly Pronk Poppenhuis De Patronella Dunois, simultaneously represents and perpetuates the growth of agency within the commissioner. This will be done through close …

Inaccuracies In Patient Self-Report Of Genetic Testing Results For Hereditary Cancer Risks Could Impact Risk-Management Practices, Brittany Faye Sears

USF Tampa Graduate Theses and Dissertations

Pathogenic variants (PV) or likely pathogenic variants (LPV) in a cancer risk gene increase lifetime risks of developing cancer. National guidelines provide evidence-based recommendations on cancer risk management (CRM) strategies tailored to the cancer risks associated with PV/LPV in different genes. Emotional responses after learning of a PV/LPV have been studied as predictors of patient adherence to CRM, but less attention has been given to whether patients remember their actual genetic test results and the impact this may have on subsequent adherence to CRM. We surveyed a group of 114 participants registered with the Inherited Cancer Registry (ICARE), all of …

Predicting Future Well-Being Among United States Youth Who Attempted Suicide And Survived, Bingjie Tong

USF Tampa Graduate Theses and Dissertations

After a non-fatal suicide attempt, survivors commonly endorse the goal of building a life worth living; however, there have been few investigations of good outcomes after non-fatal suicide attempts. Our prior study of a national sample of United States youth found that 7 years after a non-fatal suicide attempt, approximately 13% of adolescents (75 out of 574) achieved a well-being profile at or above the top quartile of non-suicidal peers, a status which we term as good future well-being (FWB). The present investigation focused on potential predictors of FWB, including self-esteem, positive mood, family connectedness, and school belongingness, drawn from …

This thesis discusses the importance of embracing religion and spirituality in the workplace as an aspect of workplace diversity. This document aims to help us understand the definition of spirituality at the workplace and its constituents.

We conducted a literature review from predominant scholars about the salience of spirituality and religion at the workplace and its relevance to building meaning, connectedness, and a sense of belonging. We will also review Maslow's theory of Human Needs, his research on human peak-experiences, and its correlation to self-actualization and transcendence.

We will present a new model of Spirituality and Religion at the workplace …

The Specifics Of Specific Learning Disability: An Analysis Of State-Level Eligibility Criteria And Response To Intervention Practices, Lora M. Williams

USF Tampa Graduate Theses and Dissertations

The field of specific learning disability (SLD) in the United States has changed considerably since reauthorization of the Individuals with Disabilities Act (IDEA; (§3007); State Education Agencies (SEAs) have been transitioning away from the severe discrepancy model of SLD identification and towards a Response to Intervention (RTI) model (Hauerwas et al, 2013). This study aimed to review SLD practices in the United States through the analysis of SEA documents and to evaluate the progress made since the reauthorization of IDEA. The aim of the current study was to provide a snapshot of 1) how SEA regulations defined SLD; 2) when …

Effects Of Downdrag On Pile Performance, Malaak Omelia Araujo

USF Tampa Graduate Theses and Dissertations

All soils settle under the weight of newly constructed embankments. In the case of MSE wall-type embankments, piles are driven prior to embankment construction. Under the weight of the newly constructed embankment, the soil surrounding the piles may settle more than the piles themselves. This downward movement potentially drags the piles down and induces a force within the pile known as downdrag. The research on the downdrag phenomenon involving cohesionless granular soils is sparse, thus the focus of this study is to investigate the effects of downdrag on pile performance driven in Florida sandy soils. A site consisting of soil …

The Impact Of Land Use Change On Hydrology Using Hydrologic Modelling And Geographical Information System (Gis), Nattachan Luesaksiriwattana

USF Tampa Graduate Theses and Dissertations

Surface and groundwater conditions in west-central Florida are highly interactive, with shallow water table and sandy soil. Land use types including forests, agricultural areas, and urbanization affect water resources differently. Change in land use, associated with expanding the urban environment to support human needs, significantly impacts surface water infiltration and runoff characteristics. Construction of infrastructures such as buildings and housing can result less water to infiltrate through the soil, with increased surface water runoff and decline in evapotranspiration. A computerized hydrologic model, Hydrological Simulation Program-FORTRAN (HSPF), couple to a spreadsheet groundwater model and a Geographical Information System (GIS) were applied …
