The Tampa Gym Study: An Ethnographic Exploration Of Gyms, Female Gym-Goers And The Quest For Fitness In Tampa, Fl, Danielle Reneé Rosen

USF Tampa Graduate Theses and Dissertations

The Tampa Gym Study was an ethnographic examination of veteran women exercisers, their workout routines, and their attitudes towards the workouts that they undertake in two Tampa area gyms. The study’s principle objective was to study “fitness culture” in these facilities and the manner in which that culture is embodied in the language women use to describe themselves and their exercise behaviors.

The obesity crisis in the United States has been significantly responsible for an increase in membership in gyms and fitness facilities nationwide. The “culture of fitness” as it is embodied in these facilities has impacted women and their …

In Another's Voice: Making Sense Of Reproductive Health As Women Of Color, Nivethitha Ketheeswaran

USF Tampa Graduate Theses and Dissertations

The goals of this project are twofold. The first goal is to articulate my sense making of reproductive health for Women of color in the United States as a postcolonial condition; one that I trace back to the logics of elimination of settler colonialism (Wolfe, 2006) and frame as maintained through the colonial institutions, or racial projects (Omi & Winant, 2015), of the Prison Industrial Complex, the welfare system, and the health care system which create and perpetuate dominant cultural narratives of “the welfare queen”, “the negligent Black mother”, and “the wily patient”. I show how these narratives colonize the …

Bamboo As A Sustainable Engineering Material: Mechanical Properties, Safety Factors, And Experimental Testing, Lorena Sánchez Vivas

USF Tampa Graduate Theses and Dissertations

With exponential global population growth occurring and associated environmentally destructive consumption of natural resources, alternative materials that are fast growing and sustainable are being sought out to satisfy human needs. One material that is fast growing and sustainable that can be used to meet most basic needs of humans (i.e. shelter, food, tools) is the plant bamboo, of the grass family Poaceae. Bamboo was used in the past by native peoples who lived in the environment where bamboo natively grows (all continents except Europe and Antarctica) with proven success for uses such as shelter, piping, tools, wells, food, fencing, baskets …

A Multi-Dimensional Macrolevel Study Of Drug Enforcement Strategies, Heroin Prices, And Heroin Consumption Rates, Alexander G. Toth

USF Tampa Graduate Theses and Dissertations

American policy makers primarily embrace a deterrent-based policing agenda to curb illicit drug trafficking and use that relies on the principles of the economic price elasticity of demand (Boynum & Reuter, 2005). This counter-drug platform includes three fundamental programs: arresting offenders, seizing illicit drugs, and eradicating horticultural sources of illicit drugs (U.S. DEA, 2015). One of the main goals of these programs is to deter illegal trafficking and use by increasing the price of illicit substances so they are no longer attractive to consumers. The United States has weathered various drug use epidemics during its history, and currently it is …

Home-Based Cognitive Monitoring: The Role Of Personality And Predictors Of Adherence And Satisfaction, Nasreen A. Sadeq

USF Tampa Graduate Theses and Dissertations

Over the last several decades, a growing awareness of the benefits of regular screening for common health conditions, such as cancer and cardiovascular diseases, has paved the way for preventative screenings to become routine in medical settings. Given that cognitive impairment is frequently reported as the number one worry of older adults, home-based cognitive monitoring may be an innovative solution that allows middle aged and older adults to take an active role in monitoring an important aspect of their health.

A Small Rna And Dna Binding Protein Contribute To Biofilm Development In Bartonella Henselae, Udoka Okaro

USF Tampa Graduate Theses and Dissertations

A biofilm, which is associated with 80% of chronic infections in humans, is formed when bacteria aggregate, attach to a substrate and secrete a matrix protecting the bacteria from host cell defenses and antibiotics. Bartonella henselae (B. henselae) is the causative agent of cat scratch disease, persistent bacteremia, and one of the most frequently reported causes of blood-culture negative endocarditis (BCNE) in patients. The ability of B. henselae to adhere to the heart valve, form a biofilm and vegetation to cause endocarditis increases the morbidity and mortality rate in infected patients. The presence of a trimeric autotransporter adhesin (TAA) called …

Roux-En-Y Gastric Bypass Attenuates Obesity-Related Liver Injury, Drew Alan Rideout

USF Tampa Graduate Theses and Dissertations

Obesity is a growing epidemic in the United States with significant co-morbidities. Non-Alcoholic Fatty Liver Disease (NAFLD) is a prevalent manifestation of obesity that can lead to cirrhosis. Roux-en-Y gastric bypass (RYGB) results in substantial long-term weight loss and resolution of obesity-related metabolic diseases. There appears to be a weight-independent molecular mechanism for the improvement of diabetes mellitus and NAFLD after RYGB, which is poorly understood. Obesity is associated with chronic inflammation that accompanies the hepatic steatosis. Through unknown mechanisms, RYGB in humans increases serum levels of the fat-derived adipocytokine, adiponectin. Adiponectin (an anti-inflammatory cytokine) is known to have a …

[X]Splaininggender, Race, Class, And Body: Metapragmatic Disputes Of Linguistic Authority And Ideologies On Twitter, Reddit, And Tumblr, Judith C. Bridges

USF Tampa Graduate Theses and Dissertations

This study investigates the language of “citizen sociolinguists,” everyday users of social network sites (SNS) who contribute to the discourses about language on Twitter, Reddit, and Tumblr, platforms with distinctive user demographics and technological affordances. The data were collected through keyword searches for mansplain, whitesplain, richsplain and thinsplain, metapragmatic neologisms which are lexical blends of the verb explain and one of four social categories. Disputes of macro-level ideologies are revealed by users’ creative meaning-making strategies and metapragmatic awareness of micro-level texts and utterances. Making use of the linguistic practices of the SNS, as well as the concisely-compacted semantic and pragmatic …

Modeling And Assessing Lava Flow Hazards, Elisabeth Gallant

USF Tampa Graduate Theses and Dissertations

Lava flow hazards are one of the few constant themes across the wide spectrum of volcanic research in the solar system. These dynamic hazards are controlled by the location of the eruption, the topography and material properties of the land upon which the flow spreads, and the properties of the lava (e.g., volume, temperature, and rheology). Understanding the influences on eruption location and how lava flows modify the landscape are important steps to accurately forecast volcanic hazards. Three studies are presented in this dissertation that address di˙erent aspects of modeling and assessing vent opening and lava flow hazards.

The first …

A Machine Learning Approach To Predicting Community Engagement On Social Media During Disasters, Adel Alshehri

USF Tampa Graduate Theses and Dissertations

The use of social media is expanding significantly and can serve a variety of purposes. Over the last few years, users of social media have played an increasing role in the dissemination of emergency and disaster information. It is becoming more common for affected populations and other stakeholders to turn to Twitter to gather information about a crisis when decisions need to be made, and action is taken. However, social media platforms, especially on Twitter, presents some drawbacks when it comes to gathering information during disasters. These drawbacks include information overload, messages are written in an informal format, the presence …

Tracking Sediment Bypassing, Geomorphological Analysis, And Regional Sediment Management At Tidal Inlets, Tanya M. Beck

USF Tampa Graduate Theses and Dissertations

Tidal inlets on sandy shorelines separate barrier islands and serve as a conduit for transport of sand and water between embayments and oceans, seas, or other tidally influenced waterbodies. Tides and waves induce currents along the coastline that transport sediment across-shore and alongshore. Coastal managers must optimize barrier-inlet system stability while conserving limited sediment resources, and often base management decisions and engineering design upon geomorphic and numerical models that predict the morphological behavior of tidal inlets on short-to-medium timescales (years to decades). The overall goal of this study was threefold. First, to provide science-based practical guidance for regional sediment management …

Exploring New Teacher Beliefs: Identity, Home-Life, And Culture In The Classroom, Frederick B. Bradley Iii

USF Tampa Graduate Theses and Dissertations

A persistent shortage of science, technology, engineering, and math (STEM) students, teachers, and professionals is seen by many as a threat to the nation’s global economic standing. Deficits in these areas are often attributed to a lack of quality K-12 STEM education, which is due in large part to a high rate of teacher turnover. Moreover, such teacher attrition has been shown to occur far more often in high-need schools and districts; thus serving to further marginalize disadvantaged members of society.

This study occurs within the context of The Robert Noyce Scholarship Program at our research-intensive university in the southeastern …

“It’S A Broken System That’S Designed To Destroy”: A Critical Narrative Analysis Of Healthcare Providers’ Stories About Race, Reproductive Health, And Policy, Brianna Rae Cusanno

USF Tampa Graduate Theses and Dissertations

Constructions of race, reproductive health, and gender have been inextricably linked in the United States since the beginning of the nation. Today, these linkages remain evident in the marked racial and gender inequities in reproductive health outcomes that persist in the U.S. To better understand how these meanings and material outcomes are negotiated and produced by actors on the ground, this study asked: “How do reproductive healthcare providers (RHPs) communicate about the intersections of race, reproductive health, and policy?” I conducted semi- structures interviews with 24 RHPs, resulting in over 35 hours of recorded interviews. Drawing on critical-cultural communication, Reproductive …

Beyond Labels And Captions: Contextualizing Grounded Semantics For Explainable Visual Interpretation, Sathyanarayanan Narasimhan Aakur

USF Tampa Graduate Theses and Dissertations

One of the long-standing problems in artificial intelligence is the development of intelligent agents with complete visual understanding. Understanding entails recognition of scene attributes such as actors, objects and actions as well as reasoning about the common semantic structure that combines these attributes into a coherent description. While significant milestones have been achieved in the field of computer vision, majority of the work has been concentrated on supervised visual recognition where complex visual representations are learned and a few discrete categories or labels are assigned to these representations. This implies a closed world where the underlying assumption is that all …

Dating Application Facilitated Victimization: An Examination Of Lifestyle-Routine Activities, Self-Control, And Self-Efficacy, Vanessa Centelles

USF Tampa Graduate Theses and Dissertations

The current study examines how college students participate in the use of location-based real-time dating (LBRTD) applications and the correlates of in-person and cyber victimization. Using an exploratory lens, the present study draws on the classical criminological theories of lifestyle-routine activities (L-RAT), self-efficacy, and low self-control which have been applied to various forms of abuse. Although the use of LBRTD applications has become relatively common place, with approximately 15% of Americans reporting having used a mobile dating application or online dating site, little is known concerning the role these applications play, particularly among college students (Boillot-Fansher, 2017; Smith, 2016). Using …

USF Tampa Graduate Theses and Dissertations

Spurred by the rapid influence of social media in the news industry, an increased number of TV news stations have started assigning dedicated social media journalists (SMJ) in newsrooms to monitor, gather, verify, share news, and engage with audiences on the streams of social media. Consequently, drawing on the diffusion of innovation theory, the present study probes into TV journalists’ perceptions of the implications of the role of this new type of TV professionals in the identity and profession of journalism, the quality of news pertaining to the verification of misinformation, and the news audiences’ attractions and viewership by capitalizing …

Plasticity In Animated Children’S Cartoons: The Neoliberal Transforming Bodies And Static Worlds Of Ok Ko And Gumball, Rachel E. Cox

USF Tampa Graduate Theses and Dissertations

Through the study of OK KO! Let’s Be Heroes! and The Amazing World of Gumball, I argue that children’s cartoons represent and recreate anxieties toward money’s plasticity in the plasticity of the cartoon bodies and worlds. I closely examine the ambivalence towards abstraction’s plasticity in contemporary children’s cartoons to trace the neoliberal ambivalence towards money’s plasticity. While much scholarship has grappled with what can be understood as animatic plasticity, very little of it takes on the questions raised about neoliberal culture by televised children’s cartoons. Cartoons are important to study in this respect because their form allows for unbridled plasticity. …

A Decision-Making Framework For Hybrid Resource Recovery Oriented Wastewater Systems, Nader Rezaei

USF Tampa Graduate Theses and Dissertations

Water shortage, water contamination, and the emerging challenges in sustainable water resources management (e.g., the likely impacts of climate change and population growth) necessitate adopting a reverse logistics approach, which is the process of moving wastewater from its typical final destination back to the water supply chain for reuse purposes. This practice not only reduces the negative impacts of wastewater on the environment, but also provides an alternative to withdrawal from natural water resources, forming a closed-loop water supply chain. However, the design of such a supply chain requires an appropriate sustainability assessment, which simultaneously accounts for economic, environmental, and …
