Teaching Caregivers To Implement The Picture Exchange Communication System: An Evaluation Of Video Modeling, Carlie Lawson

USF Tampa Graduate Theses and Dissertations

Individuals diagnosed with developmental disabilities may not develop functional vocal repertoires. For these individuals, the use of an alternative augmentative communication (AAC) system may be required. Training caregivers to use an AAC system with their children can increase communication in the home. The Picture Exchange Communication System (PECS) is type of AAC commonly used with individuals that have little to no vocal speech. Video modeling is a training procedure that has been shown to be effective when training individuals to implement behavioral analytic procedures. To date, there is no published research on the use of video modeling to train caregivers …

Using Instructive Feedback To Expand Second Language Of Children With Autism Spectrum Disorder, Barbara D. Rodriguez

USF Tampa Graduate Theses and Dissertations

There are millions of people who speak multiple languages (U.S. Census Bureau, 2019), yet there is a common misconception that teaching a child with autism spectrum disorder (ASD) more than one language will cause delays in language acquisition (Trelles & Castro, 2019). This misconception has led to fear amongst bilingual caregivers, resulting in many choosing to not speak to their child in their heritage language, which in turn can cause communication barriers between them and their child. It is imperative that a child from a bilingual home can communicate (e.g., respond to instructions) in both languages. However, because many children …

Anonymized Identity Recognition And Classification Using Privacy Preserving Facial Encoding, Manas Sanjay Pakalapati

USF Tampa Graduate Theses and Dissertations

The need for sharing large-scale datasets to train deep neural network models, particularly in healthcare, raises significant data security and privacy concerns. To address these issues, methods such as data encryption or encoding are utilized. These techniques can encrypt the data and make it unreadable to humans, while still retaining its usefulness for training models.

In this study, we investigate various image encoding techniques designed to protect privacy by making images unrecognizable while still retaining their usefulness for model training. Our investigation utilized publicly available facial databases and focused on evaluating the trade-offs inherent in image encoding techniques, with a …

Comparing The Genomes Of Multidrug And Vancomycin-Resistant Enterococcus Faecium From A Florida Wastewater Treatment Plant, Eleanor Brodrick

USF Tampa Graduate Theses and Dissertations

Vancomycin-resistant Enterococcus (VRE) are a serious health threat, causing 50,000 infections and 5,000 deaths each year in the United States (CDC, 2019). Multidrug-resistant VRE are becoming more prevalent, and treatment options for infections caused by these organisms are limited (Arias et al., 2010; CDC, 2019). Multidrug resistant VRE have been previously isolated from wastewater in Brazil, Canada, and Portugal (Araújo et al., 2010; de_Farias et al., 2022; Sanderson et al., 2019). Thirteen vancomycin-resistant Enterococcus faecium isolated from three stages of a Florida wastewater treatment plant were fully resistant to the following antibiotics: vancomycin, ampicillin, ciprofloxacin, erythromycin, tetracycline, and nitrofurantoin, and …

The Power Of Class Consciousness: An Investigation Of Permeability Beliefs, Dehumanization, And Evaluations Of The Poor, Kirsten J. Lee

USF Tampa Graduate Theses and Dissertations

Class consciousness, a theoretical construct from the Marxist tradition, promotes an understanding of class dynamics as a structural phenomenon. I hypothesized that class consciousness would moderate animalistic dehumanization of the poor. A total of 435 participants took an online survey containing self-report questionnaires. While a priori hypotheses related to animalistic dehumanization were not supported, exploratory analyses revealed that permeability beliefs—the degree to which an individual sees class boundaries as impermeable—moderate emotional tone when discussing the rich and the poor. Mirroring Marx’s theorizing, those with class consciousness spoke more positively of the poor and less favorably of the rich than their …

Patrol Car Swab Sampling For Biological Agents, Haylie Corcho

USF Tampa Graduate Theses and Dissertations

Law enforcement personnel have a variety of responsibilities and subsequently, a variety of different exposures. Biological agents are common in the environment and therefore, these exposures are a concern in the profession. There is a gap in research into biological agent exposures in this profession, particularly how it relates to surface contamination and within the officers’ vehicles. There is also a lack of standardized decontamination procedures for patrol vehicles, allowing for the potential persistence of these agents. The purpose of this study is to understand which biological agents are most common in patrol cars, which areas within the vehicles have …

Examining The Effectiveness And Acceptability Of A Single-Session Problem-Solving Teleconsultation Package With Caregivers, Tiara J. Rowell

USF Tampa Graduate Theses and Dissertations

This study implemented a single case concurrent multiple baseline design to examine the effects of a single-session problem-solving teleconsultation package for behavioral caregiver training. This study sought to address a gap in the Problem-Solving Consultation (PSC) literature regarding the treatment of children’s challenging behaviors. Participants included three caregivers who received a single-session PSC through teleconsultation. The session focused on creating a Behavior Intervention Plan (BIP) in order to address their child’s challenging behaviors. The BIP was developed based on baseline data, questionnaires, and emails exchanged between the consultant and the three caregivers. Results indicated that two of the three caregivers …

Skinny And Curvy And Muscular, Oh My! Examining Co-Occurring Appearance Ideals And Associated Disordered Eating In College Women, Laura E. Boyajian

USF Tampa Graduate Theses and Dissertations

Research examining appearance ideal internalization has primarily focused on the thin ideal, neglecting the growing importance of alternative appearance ideals (e.g., curvy, muscular). Qualitatively, women report that these ideals are not internalized in isolation, but instead, are internalized simultaneously. Importantly, the simultaneous internalization of appearance ideals may enhance the negative effects of appearance ideal internalization. The current study tested whether simultaneously internalizing diverse appearance ideals (i.e., thin, curvy, muscular) was associated with increased body dissatisfaction and disordered eating behaviors in a predominantly White (Study 1; N= 260) and racially/ethnically diverse (Study 2; N=264) samples of college-aged women. Participants reported the …

From Guns To Intimate Partner Violence: The Impact Of Power And Control, Meaghan E. Brown

USF Tampa Graduate Theses and Dissertations

Gun violence and intimate partner violence are pervasive public health concerns across the globe. Notably, previous literature has shown a positive relationship between gun ownership and intimate partner violence (IPV), even when a gun is not used during acts of IPV. Despite this established link, few studies to date have explored psychological mechanisms, especially feelings of and desire for power, that could explain this relationship among young men. Given that college students remain one of the most at-risk groups for both victimization and perpetration of IPV, examining the relationship between actual or intended gun ownership and IPV could close vital …

“She’S On Her Way Up”: A Case Study Of Mercy Otis Warren And The Gendered Politics Of Commemoration, Sara Ann White

USF Tampa Graduate Theses and Dissertations

In 2001, a statue of eighteenth-century Bill of Rights advocate Mercy Otis Warren was erected on the Barnstable County Superior Courthouse lawn in Barnstable, Massachusetts. The story of the statue’s eventual placement is a fascinating case study of how the gendered politics of commemoration can play out over time in local communities. The saga of Warren’s commemoration is inextricably bound up with the history of efforts to commemorate Warren’s brother, James Otis Jr., and eventual arguments that Warren’s work deserved recognition in its own right. We first see gendered politics at play as Warren’s real accomplishments were consistently overshadowed by …

A Cca Analysis Of How Media Cover Military Policies Regarding Trans Service Members And Veterans: Implications For Policy, Healthcare, And Wellbeing, Jonathan T. Baker

USF Tampa Graduate Theses and Dissertations

The military is the leading employer of transgender and gender diverse (trans) people in the United States, and trans people are twice as likely to serve in the U.S. Military compared to the national average. This dissertation analyzes newspaper coverage of transgender service members and veterans between the end of President Obama’s administration and the early months of President Biden’s administration. Guided by the Culture-Centered Approach (CCA) this dissertation focused on cross-paradigmatic questions regarding the role of voice (e.g., quoting or paraphrasing various sources) in this coverage. Specifically, I assessed (a) which groups of people are being cited most often, …

An Evaluation Of Reinforcement Thinning Using Deposit Contracts To Increase Physical Activity, Madeline N. Mccullen

USF Tampa Graduate Theses and Dissertations

Due to the health risks associated with a sedentary lifestyle, researchers have used behavioral interventions such as contingency management and deposit contracts to increase physical activity. Although these interventions have been effective, researchers have described the lack of maintenance assessments of the target behavior. One way to address the maintenance of behavior, such as physical activity, is with reinforcement thinning. The current study evaluated the effects of self-tailored deposit contracts and reinforcement thinning on daily step count with sedentary adults using a nonconcurrent multiple baseline across participants design. Researchers and participants designed a self-tailored deposit contract by identifying a step …

Investigation Of Self-Assembly Of Hen Egg White Lysozyme Fibrils, Nabila Bushra

USF Tampa Graduate Theses and Dissertations

Amyloid proteins are a large group of proteins that tend to aggregate and form insoluble fibrils with a characteristic cross-β sheet structure. Intriguingly, this process of “amyloid formation” has been simultaneously linked to devastating human diseases called amyloidoses, ranging from Alzheimer’s Disease, cardiac amyloidoses to type II diabetes, as well as functional biological responses such as hormone storage and sperm quality control. Amyloid fibrils have also attracted significant attention for their unique mechanical, chemical, and optical characteristics, establishing them as promising tough biomaterials. The urgent need to find treatments for Alzheimer’s disease, and the demand for safe and renewable biomaterials …

Sars-Cov-2 Neurotropism: Understanding Effects At The Blood-Brain Barrier And Hematogenous Neuroinvasiveness, Taylor E. Martinez

USF Tampa Graduate Theses and Dissertations

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, has provisional counts of over 110 million documented cases and 1.218 million deaths (as of February 2024) in the United States since January 2020. SARS-CoV-2 is an airborne respiratory virus that primarily infects the lungs via the ACE2 receptor but has well-documented secondary target organs including the kidneys, the gastrointestinal tract, the heart, and the skin. SARS-CoV-2 also infects the brain, but the hematogenous route of viral entry to brain is still not fully characterized. Understanding how SARS-CoV-2 traverses the blood-brain barrier (BBB) as well as how it …

Predicting Ph At In-Situ Temperature For Aquatic Environments, Sarah E. Bartoloni

USF Tampa Graduate Theses and Dissertations

pH is typically measured at a constant temperature and, as needed, converted to in-situ temperature using a system of thermodynamic equations. Using this equilibrium approach, adjustment of pH to in situ conditions requires two measured CO2 system parameters (pH, total alkalinity, dissolved inorganic carbon, or CO2 fugacity). Currently, when pH is the only measured CO2 system parameter, linear models are used to adjust the pH to in-situ temperature. Although many studies have attempted to optimize CO2 equilibrium constants (K1 and K2) for the CO2 system over a range of conditions, very little prior work has experimentally examined which CO2 system …

Navigating Shrinking Cities: Towards Coordinated Urban Development From The Perspective Of Flow And Network, Yuzhou Chen

USF Tampa Graduate Theses and Dissertations

As cities worldwide undergo rapid but uneven changes, proposing smart and sustainable urban development strategies has been a popular interdisciplinary research in the 21st century. In particular, the phenomenon of shrinking cities characterized by economic recession and population decline is becoming increasingly severe in developed countries and even developing countries. In the real world, research focusing on individual shrinking cities often neglects the interconnectedness between cities within the network formed by flows. Therefore, coordinating the development strategies for multiple closely connected cities, especially for shrinking cities, is a step up from focusing on individual cities.

This dissertation aims to propose …

Essays On The Determinants Of Women's And Children's Health In Bangladesh, Md Shahjahan

USF Tampa Graduate Theses and Dissertations

My dissertation is titled "The Determinants of Women's and Children's Health in Bangladesh." The first chapter studies the impact of a Bangladeshi schooling program on child immunization rates. The program provided a stipend and other incentives to attend secondary school, significantly increasing rural girls' education. I hypothesize that this would lead to higher immunization rates in the next generation since better-educated mothers have better knowledge of health practices. The study uses a regression model ("difference-in-differences"), which is based on differential exposure to the 1994 Female Secondary School Stipend Program (FSSSP) by birth cohort and rural residence. I find that the …

Did I Do That?: Lived Experience And Media Representation Of The Awkward Black Girl, Kendra Williams

USF Tampa Graduate Theses and Dissertations

For my thesis project I will introduce the Awkward Black Girl as a new race gender script. Though there are minor nuances of the Awkward Black Girl within television, Issa Rae’s performance of the Awkward Black Girl in Misadventures of Awkward Black Girl and the HBO hit series Insecure remains prevalent to contemporary media representations. Though there is limited scholarship within the field of Communication available about the Awkward Black Girl, most of the scholarship consists of analysis and discourse centering Rae’s portrayal in her web series and television show. I explore Quinta Brunson’s portrayal of the Awkward Black Girl …

Confronting Sexism On Tiktok: Is Sarcastic Humor Effective?, Rebecca A. Upton

USF Tampa Graduate Theses and Dissertations

Confronting sexism is important but can be difficult because of the social backlash that is associated with it. However, many individuals have begun to call out sexism online. For example, the social media platform TikTok is an increasingly popular space for women to confront misogyny. In one current trend, creators target individuals who create sexist content by using sarcasm to humorously mock their original video. In this study, I examined the effectiveness of this trend in persuading observers and how the use of sarcastic and mocking humor influences perceptions of a woman confronting sexism. 492 participants were randomly assigned to …

Tetr Family Regulator, Farr, Influences Rot-Mediated Control Of Virulence Factor Expression In Staphylococcus Aureus, Julia C. Schumacher

USF Tampa Graduate Theses and Dissertations

Point-mutation variants of the TetR family regulator, FarR, have emerged across Staphylococcus aureus sequence types as conferring antibiotic and fatty acid resistance, particularly in Hospital-Associated Methicillin Resistant S. aureus (HA-MRSA) strains. FarR also exhibits an additional largely uncharacterized relationship to virulence factor production, seemingly through the global repressor of toxins—Rot, which functions to regulate S. aureus’ ability to colonize and persist in the host via a complex cascade of signaling. While Rot protein is post-transcriptionally regulated by the highly characterized Agr system, there is little known about its transcriptional regulation. Herein, we explored these dynamics by initially characterizing virulence phenotypes …

Uprooted, Displaced, Resilient: Kosovar Women’S Narratives Of Organizing For Survival During The Kosovo War, Erjona Gashi

USF Tampa Graduate Theses and Dissertations

The goal of this dissertation is to foreground Kosovar women’s narratives and organizing properties during the Kosovo War. I examine the overlooked gendered roles and day-to-day lived experiences of Kosovar women, survivors of the Serb genocide, political violence, and oppression, and investigate their organizing properties during the Kosovo War (1998-1999). In acknowledging women’s plurality of experiences and perspectives, I challenge the currently pervasive and monolithic narrative of women as passive victims of war present in scholarship in organizational communication and instead make overt the narrative of women as critical organizational actors that sustain lives during and after the war. Using …

The Friendship Train: Peas, Politics, And Propaganda, Miller Scott

USF Tampa Graduate Theses and Dissertations

On a brisk fall night in November 1947, more than 100,000 people packed the streets of Hollywood to celebrate the launch of the Friendship Train. High-ranking government officials, business leaders, and a galaxy of film stars all attended the send-off ceremony. Over the next eleven days, the train traveled across the country, gathering essential foodstuffs to send to hungry Europeans. In small towns and big cities, the train received enthusiastic receptions. Its journey ended in New York City with a ticker-tape parade down the iconic Canyon of Heroes. Along the way, it collected more than 200 boxcars of food, worth …

Organizing Queer Civil Rights Movements: Pride Parades And Communicative Dilemmas, David J. Dooling

USF Tampa Graduate Theses and Dissertations

Pride parades (“Pride”) are sites of communicative tension for the queer community. While the political origins of queer civil rights practiced widespread resistance to institutional heteronormativity and homophobia, Pride is a space where business owners, community stakeholders, and activists debate the political utility of queerness. This dissertation employs queer and sociomaterial theoretical traditions, and autoethnographic methodological approaches to explore the communicative strategies of Pride organizers—individuals who create, coordinate, and conceptualize the display of sexuality and gender in the public sphere. I draw on tension-centered approaches to organizational communication, feminist dilemmatic theorizing, and co-sexuality to investigate power-laden structures and decision-making in …

“A Second Chance Citizen Reintegration Program Through The Lenses Of Black And Brown Participants And Case Managers.”, Bobbie Straughter

USF Tampa Graduate Theses and Dissertations

Recidivism has been linked to a lack of education opportunities, heightened surveillance, a lack of housing stability, and limited access to resources for assistance. Because Black and Brown communities are facing mass incarceration, there is a growing concern about recidivism, as they are affected by several factors that may make them more likely to re-offend upon release. These include a lack of mental health outreach, their socioeconomic status, environmental influences, and the challenges they face regarding their masculinity and role in fatherhood. To both reduce recidivism and provide a solution to the obstacles presented above, the literature suggests providing re-entry …

Spectral Properties Of Wetlands In Michigan Using Remote Sensing To Identify And Classify Wetlands In Roscommon County, Michigan, Kolin Williamson

USF Tampa Graduate Theses and Dissertations

Biological, geological, and physical. These are only a handful of the many environmental aspects that wetlands functions maintain and protect. Unfortunately, wetlands within the United States have been razed at an alarming rate. The State of Michigan has not gone through this unscathed either, loosing over 1000 acres of wetland a year. One of the most important tools to prevent this destruction are the maps and programs that show where these essential ecosystems are located. The current, federally-created maps and imaging software in use by environmental consultants and contractors may not be up to date which can pose challenges for …

Public-Private Partnerships In Student Housing: A Qualitative Content Analysis Of Acuho-I Publications, Ana Mercé Mcdermott Hernandez

USF Tampa Graduate Theses and Dissertations

This study examines public-private partnerships (P3s) as represented in the Association of College and University Housing Officers – International (ACUHO-I) publications from 1951-2023 and shares themes and patterns found. P3s have been used for on-campus student housing since the 1960s, yet the method is not well represented in the discourse of the student housing profession. The purpose of this qualitative content analysis is to serve as a resource for higher education administrators to support the evaluation of the P3 methodology for future student housing projects.

Less than 2% of the 12,264 ACUHO-I publication entries reviewed were related to on-campus student …

The Effect Of Fixed Time Delays On The Synchronization Phase Transition, Shaizat Bakhytzhan

USF Tampa Graduate Theses and Dissertations

Nature is full of synchronization phenomena, which are essential to many scientific fields like biology, chemistry, physics, and neuroscience. The Kuramoto model is a well-known theoretical model that helps explain the fundamental ideas behind synchronization dynamics [6]. Nevertheless, in practical situations, systems frequently display intrinsic latency, which can greatly impact their behavior during synchronization. This insight inspired our work, which looks at the results of adding temporal delays to the Kuramoto model. In particular, we investigate how the system’s synchronization dynamics are affected by delays. We shed light on the mechanisms underpinning synchronization in the face of temporal delays and …

Slot Machine Addiction: The Untold Story Of Contradictions Between Self And America's Neoliberal Risk Society, Melanie C. Falconer

USF Tampa Graduate Theses and Dissertations

The ability to take risks is nothing short of heroism in the modern United States which thrives on a diet of hyper mobility, technological progress, and globalized, deregulated “free” markets. Such relentless instability affirms scholarly contentions that the U.S. is now a “risk society.” Indeed, in Gambling with the Myth of the American Dream: The Pokerization of America, rhetoric scholar Aaron Duncan suggests that media stories of modern poker tournaments signify a collective desire to grapple with this heightened modern “chanciness” within our established gambling lore and make it cohere with our deeply cherished notions of American individualism. While Duncan …

A Republic Of Pawprints: The Rise And Reign Of The Alaskan Sled Dog, 1870-1970, Christopher David Adkins

USF Tampa Graduate Theses and Dissertations

This dissertation charts the career of the Alaskan sled dog: how it was used as an engine of development, how it became a symbol for early American Alaska, and how it fell victim to obsolescence as newer and faster means of conveyance became available. The figure of the sled dog in the Arctic is complex. Because it was closer to the wolf in phenotype both it, and Alaska, were buffeted by the same White settler expectations and Darwinian chauvinism which afflicted its Indigenous peoples. This would intensify during the baptisms by fire of the gold rushes. Dog abuse – overwork, …
