Counseling Clients With Traumatic Brain Injury: Exploring Counselors’ Perceived Knowledge, Comfort, And Self-Awareness, Michelle Bradham-Cousar

USF Tampa Graduate Theses and Dissertations

The number of traumatic brain injury (TBI) diagnoses continues to rise each year. Counseling is a critical factor in TBI treatment, and although numerous studies have investigated TBI outcomes, a paucity of researchers have studied professional counselors’ knowledge, comfort, and self-awareness when working with TBI clients. Due to the diversity of counselor caseloads, it is likely that counselors will serve clients with a dual diagnosis that includes TBI. These dual diagnoses include depression, posttraumatic stress disorder, anxiety, psychosis, or another neurocognitive disorder. The purpose of this study was to explore counselors’ knowledge, comfort, and self-awareness when working with individuals with …

Data-Driven Modeling Of The Causes And Effects Of Interneuronal Dysfunction In Alzheimer’S Disease And Dravet Syndrome, Carlos Perez

USF Tampa Graduate Theses and Dissertations

One of the defining features of Alzheimer’s disease (AD) is the increased cleavage of the amyloid precursor protein (APP), causing abnormally high levels of the aggregation form of amyloid beta (Aβ ). Many studies have shown that both AD patients and AD mice models exhibit abnormal network activity, including hypersynchronous excitatory neuron behavior, altered brain rhythms, and in some instances epileptic seizures when exposed to high levels of Aβ In particular, strong experimental evidence suggests that it is the small globular amyloid oligomers (gOs) and curvilinear fibrils (CFs) rather than the more stable, late stage rigid fibrils (RFs) that cause …

Quantifying The Impact Of Chronic Stress On Racial Disparities In Cardiovascular Disease, Nnadozie Emechebe

USF Tampa Graduate Theses and Dissertations

Background: Despite declining mortality in cardiovascular diseases (CVD), racial disparities between non-Hispanic Blacks (NHB) and to non-Hispanic Whites (NHW) persist. Although the prevalence of traditional risk factors of CVD such as hypertension, is higher in NHB compared to NHW, adjusting for this difference does not eliminate the disparity completely. This suggests other factors might explain the persisting disparities. Thus, the purpose of this dissertation is to quantify the impact of chronic stress in explaining the racial disparities in cardiovascular diseases (CVD). This dissertation contains three studies that addressed the following Specific Aims: Specific aims: 1) To create and assess the …

Evaluating The Effects Of Peer Competition On Physical Activity During School Recess, Heather M. Zerger

USF Tampa Graduate Theses and Dissertations

With an increase in childhood obesity, engagement in regular physical activity is an important health-related behavior. In addition to being overweight or obese, a lack of physical activity can lead to other serious health risks. With children spending a majority of their weekdays at school, this environment should be used to promote physical activity. The purpose of the current study was to evaluate the effects of peer competition and feedback on children’s step counts. During baseline, participants wore a sealed pedometer during recess and physical education (PE). During intervention, participants with higher step counts were paired with participants with lower …

Isolation Of Specific Phospholipids From Nannochloropsis Oculata Microalga For Cosmetic Applications, Ahmet Yener Manisali

USF Tampa Graduate Theses and Dissertations

Algae, photosynthetic aquatic organisms, have recently caught the attention of the food, cosmetic, pharmaceutical, and nutraceutical industries due to the variety of natural compounds in their cellular bodies such as carbohydrates, lipids, and proteins. Specifically, microalgae-derived natural compounds such as phospholipids are extensively utilized in cosmetics as part of liposome formers, emulsifiers, solubilizers, and wetting agents. Although phospholipids are currently extracted from food sources, this practice raises sustainability concerns. Hence, growing microalgae on the provision of macronutrients such as nitrates and phosphates will serve as a more sustainable source of the several specific phospholipids such as phosphatidylcholine (PC), phosphatidyl-ethanolamine (PE), …

Circadian Rhythms And The Embodiment Of Social Zeitgebers: Linking The Bio And Social, Tiffany R. Moore

USF Tampa Graduate Theses and Dissertations

Virtually all biological processes are under direct or indirect control of the circadian system. Chronic disruption of circadian rhythms, termed chronodisruption, is linked to increased risk for adverse health outcomes such as cancer, depression, and cardiometabolic disease. Circadian rhythms are highly sensitive to sociocultural contexts. As a result, circadian rhythms provide a valuable entryway to explore issues of embodiment. Here, embodiment refers to processes through which social experiences ‘get under the skin’ to become biological and manifest in health. To better understand what proximate social factors influence chronodisruption, this study assessed chronodisruption and social zeitgebers among a population of 15 …

Modeling Early Life: Ontogenetic Growth And Behavior Affect Population Connectivity In Gulf Of Mexico Marine Fish, Kelly Vasbinder

USF Tampa Graduate Theses and Dissertations

This dissertation is an examination of growth, behavior, and dispersal during the early life stages of marine fishes in the Gulf of Mexico. Understanding movements of early life stages is a key part of managing exploited fish populations. Position in the water column can impact larval dispersal, since it determines those currents to which larvae are exposed. First, I investigated the relationship between length and age in early life stages of marine fishes. I found that demersal fish taxa tend to be represented by exponential models, while pelagic fish tend to be represented by linear models. I suggest this may …

This project investigates children, childhood and diet of two different Migration Period (4^th-8^th century AD) populations, the Gepids and the Avars, in the Great Hungarian Plain. The main goal was to assess whether there are differences in treatment of children and differences in breastfeeding and weaning practices in these distinct sites and populations. Secondarily, this research also focused on characterizing diet for the Gepids and the Avars at four different sites from the Migration Period, to understand how the migration and settling into the region and the assimilation of other groups into the two populations affected their …

Mapping Narrative Transactions: A Method/Framework For Exploring Multimodal Documents As Social Semiotic Sites For Ethnographic Study, Anne W. Anderson

USF Tampa Graduate Theses and Dissertations

This work grew from my attempts to find a method for studying a body of editorial cartoons—multi-modal documents producing cross-modal responses—that were created and published in an earlier time period, in order to answer questions about the culture in which the cartoons were produced and read. Initially my questions included wondering about the topics cartoonists addressed, the narratives cartoonists created to address the topics, how the narratives were framed, and in what ways the narratives might have been seen as attempts to shape the larger cultural discourse around the topics. However, given the number of possible combinations of information streams …

Hearing Aid Acclimatization In The Context Of Central Gain Mechanisms, Peter J. Hutchison

USF Tampa Graduate Theses and Dissertations

The primary goals of this dissertation were to 1) identify markers of central gain in the auditory system following short-term acoustic attenuation via earplugging and acoustic enhancement via sound generators, and 2) determine if acoustic enhancement is effective in modulating central gain in older adults with age-related hearing loss, and if so, to what extent. Additionally, a further goal of this dissertation was to explore the possibility that central gain is related hearing aid acclimatization. The results described in Chapter 2 are further evidence that altering acoustic input to the peripheral auditory system modulates central auditory plasticity and is evident …

Networks In The Norm Life Cycle And The Diffusion Of Environmental Norms, James E. Fry

USF Tampa Graduate Theses and Dissertations

In this research, I analyze how Transnational Municipal Networks (TMNs) and cities affect the diffusion and transmission of a decarbonization norm. Urban policy and political science scholars assert that cities and their networks are influential in implementing internationally coordinated environmental policy. However, few projects have analyzed how local actors may diffuse environmental norms that have been developed in the international system. Using the norm life cycle, this research explores the transmission of a decarbonization norm by means of GHG measurement and mitigation. I identify two critical objectives associated with a decarbonization norm: establishing a system for monitoring GHG emissions and …

Maternal Social Status, Offspring 2d:4d Ratio And Postnatal Growth, In Macaca Mulatta (Rhesus Macaques), Juan Pablo Arroyo

USF Tampa Graduate Theses and Dissertations

Early life exposure to stressors can disrupt growth and development, resulting in long-term compromised function and increased risk for disease throughout the lifecourse. Maternal exposure to psychosocial stressors (i.e., stressors derived from social status, social inequalities, and social interactions) during pregnancy has been associated with reduced fetal growth, adverse birth outcomes, and increased morbidity for the offspring later in life. Maternal hormonal responses to stress, such as fluctuations in glucocorticoids (e.g., cortisol) and androgens (e.g., testosterone), can result in increased developmental instability, interfere with offspring growth in-utero, and may alter developmental processes of sexual dimorphism. Second digit to fourth digit …

Environmental Influences On Expression Of Virulence- And Survival-Associated Genes And Epigenetic Modifications Of Dna In Vibrio Vulnificus, James W. Conrad

USF Tampa Graduate Theses and Dissertations

Vibrio vulnificus is an autochthonous inhabitant of warm, brackish coastal waters and is an opportunistic pathogen that causes the highest mortality of all seafood-related illnesses (1). These fatal infections are generally caused by the clinically-associated vcgC/16S rRNA type B genotypes within the biotype I group (2–5). However, the reasons for the heightened infectiousness of the clinically-associated strains over environmentally-associated ones remains elusive, as no unique clinically-associated virulence genes have been identified through genomic sequencing or other strategies. DNA methylation may contribute to regulation of virulence by affecting gene transcription, and was investigated in the highly virulent V. vulnificus strain CMCP6. …

Tuning Degradation And Cell Adhesion In Next Generation Resorbable Implants, Ufuomaroghene Ikoba

USF Tampa Graduate Theses and Dissertations

Osteoarthritic and bone degenerative diseases are expected to grow immensely as the aging population, 65 years and older increases. Orthopedic implants are one sub-class of medical devices that are used to treat bone breaks and fractures. Traditionally, internal fixation implants are manufactured using titanium or stainless steel. Magnesium, a bioresorbable and biodegradable material, has been proposed as an alternative to titanium and stainless steel. The goal of this research is to control the degradation behavior of magnesium implants by developing crystallized thin poly(lactic acid) copolymer films as protective coatings. To do this, this work was divided into two aims. Aim …

Posttranslational Modification And Protein Disorder Regulate Protein-Protein Interactions And Dna Binding Specificity Of P53, Robin Levy

USF Tampa Graduate Theses and Dissertations

p53 is an intrinsically disordered transcription factor that suppresses tumor development by arresting the cell cycle and promoting DNA repair. p53 deletions or mutations can lead to cancer due to the inability of cells to respond to stress. The protein levels and post-translational modification state of p53 changes in response to cellular stress like DNA damage. Previous studies have shown that p53 can undergo coupled folding and binding with the E3 ubiquitin ligase, Mdm2, and the histone deacetylase, p300. In normal cells, p53 is kept at a low level by Mdm2, which marks it with ubiquitin, targeting p53 for proteasome …

Spatial And Temporal Determinants Associated With Eastern Equine Encephalitis Virus Activity In Florida, Kristi M. Miley

USF Tampa Graduate Theses and Dissertations

Eastern Equine Encephalitis virus (EEEV) is considered the most pathogenic mosquito-borne illness in the United States. Human mortality has been estimated to range between 35 to 75%, with horses experiencing mortality rates greater than 90%. A large number of EEEV cases occur in Florida. Though we have come a long way since the first human infection was identified in the 1930s, there is still much to learn regarding the virus’s ability to maintain transmission year-round in Florida. Phylogenic studies support that Florida may serve as the geographic reservoir for EEEV. This research investigated spatiotemporal and ecological variables associated with risk …

The Role Of Non-Secular Involvement Towards A Comprehensive Community Approach For Addressing Opioid Use Disorder, Amanda Gene Sharp

USF Tampa Graduate Theses and Dissertations

While the opioid overdose crisis continues to impact individuals, families, and communities across the United States, there is a sense of urgency to identify effective, efficient, and feasible approaches for curbing the death toll. It is clear, however, that without community-level acceptance of treatment and harm reduction approaches shown to be successful, the services available remain underutilized and thus less impactful than clinical evidence demonstrates. To overcome an opioid use disorder (OUD), an overall treatment approach should be tailored to an individual’s needs but might include components of medication, psychosocial support services, community engagement, and the development of healthy social …

Evaluation Of Aging And Genetic Mutation Variants On Tauopathy, Amber M. Tetlow

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) is characterized by amyloid β plaques and neurofibrillary tau tangles (NFTs). While research has demonstrated amyloid pathology occurs prior to tau pathology, or tauopathy, tau has proven to be more toxic. Tauopathy is associated with cognitive declines and neurodegeneration. These findings have highlighted the importance of further understanding tauopathy. In the progression of tauopathy, there is an observable immune response that can be measured by glial cells such as microglia. Activated microglia are known to exacerbate tauopathy rather than reducing the pathology. Research has indicated that with increased age there is an increased risk for AD-related tauopathy …

A Novel Magnetic Respiratory Sensor For Human Healthcare, Kee Young Hwang

USF Tampa Graduate Theses and Dissertations

Breathing is vital to life. Therefore, the real-time monitoring of a patient’s breathing pattern is crucial to respiratory rehabilitation therapies such as magnetic resonance exams for respiratory-triggered imaging, chronic pulmonary disease treatment, and synchronized functional electrical stimulation. While numerous respiratory devices have been developed, they are often in direct contact with a patient, which can yield inaccurate or limited data. In this study, we developed a novel, non-invasive, and contactless magnetic sensing platform that can precisely monitor a patient’s breathing, movement, or sleep patterns, thus providing efficient monitoring at a clinic or home. A magneto-LC resonance (MLCR) sensor converts the …
