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 …

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 …

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 …

Save Water Drink Wine: Challenges Of Implementing The Ethnography Of The Temecula Valley Wine Industry Into Food-Energy-Water Nexus Decision-Making, Zaida E. Darley

USF Tampa Graduate Theses and Dissertations

This study demonstrates the interrelationships of people, food, energy, and water associated with Temecula Valley’s wine industry and reveals contradictions and biases in how people view these resources, which ultimately shape management and policies. The FEW (Food, Energy, and Water) Nexus is an approach increasingly used by policy- and decision-makers to understand the interrelationship of several resources. However, a FEW Nexus approach often lacks in social aspects that influence environmentally and economically sustainable outcomes, especially in the wine and wine tourism industry. When quantitative and qualitative data are available, the other challenge is which assessment to use. Two assessments often …

Feasting On Words: What University Students Learn When They Study Food Writing And Food Media, Janet K. Keeler

USF Tampa Graduate Theses and Dissertations

The use of food in college curriculum is unique in its ability to create lasting impact because of the keen interest millennial and Generation Z students have in what they eat and drink. Studying media with food at its core is an underutilized mechanism to show how food intersects with the lives of all people thus encouraging students to look beyond their own experiences to consider the wider society. A program evaluation of 10 semesters of food writing and food media courses at a Florida public university reveals the ways in which students make deeper connections to culture and current …

The Use Of Spanish Moss As A Biological Indicator To Examine Relationships Between Metal Air Pollution, Vegetation Cover, And Environmental Equity In Tampa, Florida, Yousif Abdullah

USF Tampa Graduate Theses and Dissertations

Studies of inequality in exposure to less common air pollutants, like metals, are often limited by the costs of high spatial resolution measurements. Spanish moss (Tillandsia usneoides) is a promising bioindicator for measuring air pollution due to its lower cost, enabling capture of time-average environmental concentrations at high spatial resolution. This study had three major aims. First, I aimed to use Spanish moss as a bioindicator to characterize ambient concentrations of selected metals (Ti, Cr, Mn, Co, Ni, Cd, Hg, Pb, As, and Sb) in Tampa, Florida. My second goal was to determine the impact of vegetation cover on metals …

The Quantification Of Heavy Metals In Infant Formulas Offered By The Florida Wic Program, Naya Martin

USF Tampa Graduate Theses and Dissertations

Many infants rely on the WIC program to provide their main source of sustenance in theform of infant formula. In 2016, about 86% of the eligible infant population participated in this program. Infants in Florida account for about 30% of participation in the Southeast. For this reason, it is necessary to ensure that the formulas offered by this program provide the best opportunity for an optimal health outcome.

Bodily Harm: An Analysis Of The Phenomenological And Linguistic Aspects Of Harm And Trauma, Grant Samuel Peeler

USF Tampa Graduate Theses and Dissertations

This work seeks to explore the phenomenological experience of harm through an investigation of trauma and its existential features. Harm, despite its importance for many topics in both Political Science and Political Theory, is not often investigated as a subject in itself. By interrogating elements of Merleau-Ponty’s uniquely embodied philosophy, this work seeks to further our understanding of harm as a phenomenon which is both uniquely subjective and yet socially informed.

The text is split into two halves – with the first offering an exegesis of relevant sections of Merleau-Ponty’s Phenomenology of Perception, and the second engaging with contemporary secondary …

Feeding Specificity Of The Photosynthetic Sacoglossan Sea Slug Elysia Papillosa, Kourtney Sui Barber

USF Tampa Graduate Theses and Dissertations

The sacoglossan sea slug, Elysia papillosa is associated with two species of the siphonaceous green alga, Penicillus, which co-occur in mixed macrophyte beds at Tarpon Springs, FL, USA. Field collections revealed that Elysia papillosa is frequently collected from the alga, P. capitatus, but is also present in much lower abundance on P. lamourouxii. Past studies have shown that some species of sacoglossans consume algal species that differ from the algae from which they are collected so, in order to determine whether E. papillosa was consuming either or both species of Penicillus, total DNA was extracted from individual slugs collected from …

Detecting Symptoms Of Chronic Obstructive Pulmonary Disease And Congestive Heart Failure Via Cough And Wheezing Sounds Using Smart-Phones And Machine Learning, Anthony Windmon

USF Tampa Graduate Theses and Dissertations

Chronic Obstructive Pulmonary Disease (COPD) and Congestive Heart Failure (CHF) are progressive disorders, and major health concerns among today’s aging population. COPD causes a large mucus buildup in the lungs, leading to chronic cough and difficulty to breathe. CHF causes fluid buildup in the lower lungs due to the failing heart, causing cough and difficulty to breath. People who are clinically diagnosed with COPD or CHF are expected to regularly monitor their symptoms and follow complex medical recommendations in an effort to prevent exacerbation. In this dissertation, we elaborate upon three different machine learning based techniques that we developed for …

As there is little in the published literature that describes postpartum K–12 teachers' experiences while pumping breastmilk in the workplace. There is a need for studies that highlight these experiences and explore how policies impact breastfeeding teachers. The study was guided by three research questions: (1) How do classroom teachers who are, or have been, lactating and expressing milk during their workday experience school/district policies related to lactation and breastmilk expression? (2) …

Competition In Upstream Humanitarian Supply Chain: Investigation Of Food Banks, Iana Shaheen

USF Tampa Graduate Theses and Dissertations

Global hunger is not about a shortage of food. Currently, the world generates enough food to sustain every man, woman, and child on the planet. However, in 2018, about 815 million people, or almost 11% of the population, were hungry worldwide (World Hunger Report, 2018). To respond to the problems in ways more adapted to the requirements of people in need, humanitarian organizations (HOs) are dedicated to becoming more effective and efficient (Weiss, 2013). With the boost in the number of people that require humanitarian assistance, the number of HOs is increasing each year. As a result, there is unanimity …

Spatial Heterogeneity Utilization In Ct Images For Lung Nodule Classication, Dmitrii Cherezov

USF Tampa Graduate Theses and Dissertations

Lung cancer (LC) is leading in the number of deaths among the other types of cancer. According to the American Cancer Society, 135,720 deaths during 2020 in the USA will be associated with LC. The patient 5-year survival rate of 16\% was reported in 1986 and 19% in 2019. One of the reasons why survival rate remains low is that the majority of patients diagnosed with cancer had stages III and IV. In contrast, a 5-year survival rate of 70% was reported for patients of stage IA after surgical resection in the National Lung Screening Trial.

CT screening detects a …

How Can I Help My Anxious Child With Autism Spectrum Disorder? Understanding Parental Perspectives And Treatment Preferences, Sandra L. Cepeda

USF Tampa Graduate Theses and Dissertations

Despite the high prevalence of co-occurring anxiety in children with autism spectrum disorder (ASD), little is known about parental preferences for treatment in addressing these anxiety concerns. Understanding parents’ preferences for treatment is an important factor to consider for ensuring quality care, as it can guide clinical decisions with regard to implementation of care, strategies for optimizing engagement and treatment adherence, and is associated with treatment outcome. To date, limited studies have examined parental preferences in treatment for childhood anxiety or ASD; but no study has investigated preferences for treatment in children with comorbid symptoms. Thus, the present study sought …

Development Of An Organic Processor Assembly (Opa) For Sustainable Resource Recovery To Enable Long-Duration, Deep-Space Human Exploration (Loddshe), Talon James Bullard

USF Tampa Graduate Theses and Dissertations

Long-Duration, Deep-Space Human Exploration (LoDDSHE) missions demand robust and reliable technologies to ensure crew health, safety, and mission success. In situ food production will become essential for these missions for crew nutrition, morale, and in the event of delays or failures. At a current estimated cost $10,000/lb, mass and volume limitations will restrict necessary resources. For an anticipated thirty-month mission to Mars, these costs will increase due to more frequent resupply shipments and lengthened transit times, creating additional financial and logistical challenges (Pickett et al., 2019). Increased resource and waste recovery to achieve nearly closed-loop systems will mitigate many of …

Impact Of Heat-Related Illness And Natural Environments On Behavioral Health Related Emergency And Hospital Utilization In Florida, Natasha Kurji

USF Tampa Graduate Theses and Dissertations

Behavioral health disorders are the leading cause of disability in the United States and are known to have multidimensional effect on wellbeing. Several environmental factors are known to impact behavioral health such as weather (i.e. heat) and access to natural environments (i.e. parks and beaches). The study goals were to identify contextual factors that increase the co-occurrence of heat-related illness and behavioral health disorders, illustrate the re-utilization patterns of these co-occurring cases in Florida emergency and inpatient settings, and explore the association between behavioral health disorders such as anxiety and depression, and natural environments such as parks and beaches.

Predictors Of Nonadherence To Radiation Therapy Schedules Among Head And Neck Cancer Patients, Jennifer Lynn Miller

USF Tampa Graduate Theses and Dissertations

Nonadherence to radiation therapy schedules is a documented problem among head and neck cancer patients. This retrospective dissertation study examined whether demographics, clinical characteristics, or physical and psychological symptoms were related to nonadherence in head and neck cancer patients. The electronic medical records of 262 head and neck cancer patients at a southeastern U.S. cancer center were reviewed to determine whether nonadherence was related to symptom scores and other patient and clinical-related factors. Nonadherent patients were more likely to be female, be admitted to the cancer center as inpatients during treatment and receive outpatient IV fluids during treatment. Nonadherent patients …

From Colonial Legacy To Difficult Heritage: Responding To And Remembering An Gorta Mór, Ireland’S Great Hunger, Katherine Elizabeth Shakour

USF Tampa Graduate Theses and Dissertations

This research has two main components: first, an exploration of how communities react to socio-natural disasters through time, and second, a discussion of how communities constructed the responses to tragedies as heritage over the long term. Disasters are often conceived as short-term, natural catastrophes, but, in reality, they are always social and natural phenomena and often impact communities for years or even decades. Employing archaeological, historical and ethnographic methods, this project examines local, regional, and national responses to social upheaval cause by prolonged food insecurity beginning with a potato blight in 1845 in Ireland. The 1845-1850 Famine was not just …

School District Responses To Food Insecurity And Poor Nutrition In High Poverty Communities, Richard Grayes

USF Tampa Graduate Theses and Dissertations

Food insecure households are described as not having enough money or other resources to meet certain needs of all of their family members at some point during the year. Milam and Towns (2014) observed, “Child hunger exists in every county in every state” (p. 2). The hunger gap has been found to contribute to the lower academic achievement of students of color, particularly those from low-socioeconomic status (Jyoti, Frongillo, & Jones, 2005).

The purpose of this study was to explore the impact of food insecurity and poor nutrition on student learning and to review district responses, particularly in elementary schools …

Role Of Thyroid Hormone Modulating Astrocyte Activation, Payal Ghosh

USF Tampa Graduate Theses and Dissertations

Astrocytes are the specialized cells in the central nervous system (CNS). They play an important role in neuronal homeostasis. When activated, astrocytes may cause neuronal inflammation and degeneration. Thyroid hormones are important in maintaining neuronal development and homeostasis. Astrocytes play a pivotal role in this process. However, the role of levothyroxine (T4) in neuroinflammation is not clear. It is hypothesized that thyroid hormone treatment will reduce the inflammatory activation in astrocytes. Available oral T4 supplementations allow accumulation of T4 in the body and cause toxicity and side effects. It is hypothesized that the encapsulation of T4 in liposomes would reduce …

Mass Spectrometry Discovery-Based Proteomics To Examine Anti-Aging Effects Of The Nutraceutical Nt-020 In Rat Serum, Samantha M. Portis

USF Tampa Graduate Theses and Dissertations

Aging is a complex physiological process that leads to the deterioration of all cells and tissues throughout the body. Aging is a major risk factor for the onset of many degenerative diseases in both the central nervous system (CNS) and the periphery, but even nonpathological aging (“normal” aging) is associated with chronic inflammation, oxidative stress, and decreased stem cell proliferation and regenerative capacity. This decreased regenerative capacity in stem cell niches is thought to be a key component underlying the aging process and many disease states associated with aging.

While the exact biological mechanisms underlying impaired stem cell proliferation and …

Predictive Validity Of Standards-Based And Curriculum-Embedded Assessments For Predicting Readiness At Kindergarten Entry, Elizabeth Ashton Decamilla

USF Tampa Graduate Theses and Dissertations

As with traditional K-12 educational settings, early childhood assessments have been a primary source of information determining whether early educational experiences have promoted children’s readiness to start school in kindergarten. The level of use of Kindergarten Entry Assessments (KEAs) has become more wide-spread to establish levels of school readiness at kindergarten entry.

This quantitative, correlational study of children in schools that have blended Head Start/Voluntary Prekindergarten funded programs examined the predictive relationships between the independent variables (i.e., VPK Assessments and Teaching Strategies GOLD) and the dependent variable of kindergarten readiness, as measured by the Work Sampling System™ (WSS). Additionally, the …

Isotope-Based Methods For Evaluating Fish Trophic Geographies, Julie L. Vecchio

USF Tampa Graduate Theses and Dissertations

Data on the movement and diets of fish during a variety of life stages are important inputs to fisheries stock assessments and marine ecosystem models. Stable isotopes may provide previously inaccessible information on movement and diet of a variety of managed and forage fish species. Here I used several novel means of interpretation for stable isotope data to infer diets and movements of several important fisheries species over both short (weeks to months) and long (lifetime) timescales. To calculate a constant partitioning offset (CPO) between the δ¹⁵N of muscle and of liver tissue, I conducted a literature search …

Targeting Cancer-Anorexia Cachexia Syndrome And Septic Inflammatory-Based Atrophy With R/S 1,3 Butanediol Acetoacetate Diester, Andrew P. Koutnik

USF Tampa Graduate Theses and Dissertations

Cancer anorexia cachexia syndrome (CACS) is a distinct atrophy disease negatively influencing multiple aspects of clinical care and patient quality of life. Although it directly causes 20% of all cancer-related deaths, there are currently no model systems that encompass the entire multifaceted syndrome, nor are there any effective therapeutic treatments. Here, we show that the VM-M3 mouse model of systemic metastasis demonstrates a novel, immunocompetent, logistically feasible, repeatable phenotype with progressive tumor growth, spontaneous metastatic spread, and the full multifaceted CACS with expected sex dimorphisms across tissue wasting. We also demonstrate that the ubiquitin proteasomal degradation pathway was significantly upregulated …

Cancer-Related Risk Behaviors And Screening Intention Among Recreational Sport Athletes, Aldenise P. Ewing

USF Tampa Graduate Theses and Dissertations

The recreational sports arena provides a venue for young adults to increase physical activity and engage in a socially supportive environment. These are both important ways to decrease the risk for chronic diseases. It is assumed that physically active individuals lead healthier lifestyles and are more attuned to their long-term health needs. Recreational sport athletes also engage in risks for adverse cancer outcomes through increased sun exposure, intake of unhealthy diets, and recreational tobacco and alcohol use. It was of interest to assess cancer-related risk factors, cancer knowledge, and theory of planned behavior constructs in this group.

This study involved …

Antarctic Deep Sea Coral And Tropical Fungal Endophyte: Novel Chemistry For Drug Discovery, Anne-Claire D. Limon

USF Tampa Graduate Theses and Dissertations

Considered the pulse controlling the biological interactions and contributing to the ecological survival of organisms, natural products have intrigued, challenged, and stimulated the scientific and non-scientific minds for millennia. Drug resistance and the lack of suitable potent drugs against neglected tropical diseases further motivate the biological activity assessment of these secondary metabolites, when possible.

This thesis describes the chemical investigation of two marine organisms and the elucidation of eight novel structures.

The study of a deep sea Antarctic coral unveils six novel terpenoid structures from three different molecular classes: sesquiterpenoid alcyopterosins, a triterpene steroid, and three prostaglandins. While mass availability …
