Effect Of Hyperoxia On Cardiac Pathophysiology In Female Guinea Pig Hearts, Chayapatou Chayawatto

USF Tampa Graduate Theses and Dissertations

Hyperoxia is widely implemented in critical care and ICU patients. The administration of a high concentration of inspired oxygen to the lung can unknowingly cause hyperoxia and thereby damaging the lungs and heart due to oxidative stress. Technically, hyperoxia occurs when the patient receives PaO2 > 200 mmHg. Major research focused on hyperoxia-induced lung injury, but nothing is known on its effect on heart. Our lab is the pioneer in understanding the effect of hyperoxia on cardiovascular remodeling using mice model. Previous results show that mice under 72 hours of hyperoxia present severe cardiac pathophysiology. This research uses Guinea pigs, which …

Impact Of Language Sampling Context On Language Productivity And Complexity, Trina J. Tolentino

USF Tampa Graduate Theses and Dissertations

Language sampling is a familiar tool in the speech-language pathologist’s (SLP’s) repertoire, used to assess a student’s language ability and inform treatment targets. The current literature has several studies comparing various dimensions of language sampling context, but with relatively small samples. The goal of this study was to identify what sampling contexts elicit the most productive and complex language, thereby contributing insight into what conditions may yield the most accurate representation of a child’s language skill, as well as the resulting intervention focus.

One-thousand thirty-seven kindergarten, first-, second-, and third-grade students (mean age [years; months] ≈ 7;5; range = 5;0-10;9), …

Interactions Between Juvenile Estuary-Dependent Fishes And Microalgal Dynamics, Ian C. Williams

USF Tampa Graduate Theses and Dissertations

The ontogenetic movement of juvenile estuary-dependent fishes upstream in estuarine settings is a phenomenon observed around the world. These movements usually coincide with a shift in diet from smaller prey, such as calanoid copepods, to larger prey, such as mysids. However, the mechanism that drives this pattern has yet to be conclusively described. Prior to the current study, zooplankton/hyperbenthos (“zooplankton”), primary production, and water quality data were collected from the Caloosahatchee River estuary in two concurrent and coordinated studies over a two-year period. One of the products of these sampling efforts was a classification of primary-producer types at the sediment-water …

Evaluation Of Response Modality In Online Discussion Boards, Tatiyanna A. Dunn

USF Tampa Graduate Theses and Dissertations

Since 2020, over 3 million students have enrolled in a postsecondary distance learning course (National Center for Education Statistics, 2020). One challenge in distant learning is fostering student engagement. Student engagement is a broad construct that refers to increasing contact between three pillars of education. Students, teachers, and course material. Past research has shown increasing engagement leads to improved student performance and instructor evaluations. Unsurprisingly, promoting student engagement is desirable for both students and instructors (Cobb, 2009). Discussion boards allow student engagement between themselves and Instructors while knowledge can still be tested. Few studies have evaluated the modality of student …

Exploring Parenthood And The Influence Of Lived Experiences On Parenting Behaviors Among Child Welfare-Involved Adults, Veronica Howell

USF Tampa Graduate Theses and Dissertations

The World Health Organization asserts the healthy development of children is essential. Cases of violence and maltreatment impede the development of children worldwide. Six in 10 adults in the general US population have reported at least one adverse childhood experience (ACE), while vulnerable populations, including child welfare-involved adults (i.e., parents and caregivers), often report more. This history is associated with higher morbidity and mortality rates alongside higher economic costs; therefore, preventing ACEs and promoting safe, stable, and nurturing relationships between parents and children is critical. The purpose of this exploratory qualitative study was to understand the meanings and responsibilities associated …

Accelerating Multiparametric Mri For Adaptive Radiotherapy, Shraddha Pandey

USF Tampa Graduate Theses and Dissertations

MR guided Radiotherapy (MRgRT) marks an important paradigm shift in the field of radiotherapy. Superior tissue contrast of MRI offers better visualization of the abnormal lesions, as a result precise radiation dose delivery is possible. In case of online treatment planning, MRgRT offers better control of intratumoral motion and quick adaptation to changes in the gross tumor volume.

The primary aspects of MRgRT workflow are MRI acquisition, tumor delineation, dose map prediction and administering treatment. It is estimated that the acquisition of MRI takes around …

An Object For Sexual Pleasure: Does Viewing Sexualized Media Predict Increases In Self And Partner Objectification Impacting Feelings Of Sexual And Romantic Closeness?, Kaitlyn Ligman

USF Tampa Graduate Theses and Dissertations

Exposure to sexually objectifying media has been linked to the objectification of the self and of one’s romantic partner (e.g., partner-objectification); yet the implications of this for romantic relationships have remained relatively unexamined. There is, however, reason to suspect that exposure to sexually objectifying media and engaging in objectification may have implications for romantic couples. When a woman frequently monitors her appearance this may undermine her ability to sexually connect with her partner and when a man views his partner as an object for sexual pleasure it may impede his ability to develop intimate feelings of relational closeness to his …

Deceptive Appeals And Cognitive Influences Used In Fraudulent Scheme Sales Pitches, Rafael J. Toledo

USF Tampa Graduate Theses and Dissertations

Fraud schemes exploit the complex interplay that results from utilizing deceptive appeals to activate underlying cognitive influences. This study was designed, first, to identify the deceptive appeals present in the messaging of fraudulent schemes and, second, to identify the underlying cognitive influences being exploited by the deceptive appeals utilized. Findings reveal that effectively used deceptive appeals work to keep viewers’ mental processes in a state of cognitive ease. This state allows cognitive influences--such as heuristics, cognitive biases, and the System 1 mind--to remain in control of mental processing; however, System 1 is prone to accept deceptive beliefs. The results of …

Queering The Weeki Wachee Mermaid And Its Renewed Aesthetic Value, Jacqueline D. Merveille

USF Tampa Graduate Theses and Dissertations

Scholars have asserted that the visual representation of womanhood responds to a cultural context, which often adheres to patriarchy and the satisfaction of the male gaze. The mediated depiction of the mermaid through time is polysemous and therefore deserves a thorough examination substantiated by robust theories. As a gendered feminine figure that complies with the patriarchal pressure of subjugation to gratify male desire, the mermaid can, however, elude the socially constructed dichotomy of genders, contributing to her agency and queerness. By investigating the Florida roadside attraction of Weeki Wachee Springs’ mermaid shows and other mediated visual depictions of the sea …

Going Flat: Challenging Gender, Stigma, And Cure Through Lesbian Breast Cancer Experience, Beth Gaines

USF Tampa Graduate Theses and Dissertations

This paper explores the decision-making process of reconstruction surgery among lesbian breast cancer patients to better understand how identity impacts healthcare decisions. Breast cancer patients experience the disease in unique ways due to gender, sexuality, race, and class, impacting their individual decisions regarding treatment plans. Many breast cancer patients face mastectomy surgery as the first plan of treatment after diagnosis. By exploring the impact of gender, sexuality, stigma, and ideas of cure, this research aims to advance research about breast cancer by recognizing why some lesbian breast cancer patients forego reconstruction surgery and instead choose to “go flat.

Screening Pathological Protein Specific Antibodies As Biomarker Discovery Tools For Neurodegenerative Disease, Yitong Li

USF Tampa Graduate Theses and Dissertations

With the increase in the average life span, the incidence of neurodegenerative diseases also increases, among which Alzheimer's disease (AD) and Parkinson's disease (PD) are the two most common types of neurological disorders. AD and PD share the same pathogenic mechanism that involves a class of proteins called beta-amyloid (Aβ), which, under the induction of some factors, changes from its natural monomeric state to the oligomers containing β-sheet, which is neurotoxic and thus leads to cell damage or apoptosis. This study focused on the selection of antibodies used as biomarkers for AD and PD. The selection of antibodies was based …

A Holistic Investigation Of Acidosis In Breast Cancer, Bryce Ordway

USF Tampa Graduate Theses and Dissertations

In the early 20th century, Nobel laureate Otto Warburg made the observation that cells of a carcinoma had considerably higher glycolytic metabolism and considerably lower oxidative metabolism compared to cells of a normal tissue. He postulated that within this observation was the key to deciphering the differences between malignant and normal tissue. It is now well established that tumors of the breast are unequivocally acidic, caused by an abnormal amount of aerobic glycolysis, colloquially known as the Warburg effect. Over the last decades, our group, led by Dr. Robert J. Gillies, has set out to characterize the causes and consequences …

The Impact Of Cannabis On Motivational Processes For Smoked Tobacco And Cigarettes, Claire M. Gorey

USF Tampa Graduate Theses and Dissertations

Cannabis and tobacco are very commonly used across the United States. Given the high prevalence of their dual use, an important health consequence of cannabis is its impact on tobacco usage rates. After all, cigarettes are a leading cause of death in the United States. Theoretical models of drug abuse suggest that cannabis cues and intoxication may be responsible for enhanced smoked tobacco/cigarette motivation. Therefore, the present research sought to assess these routes via two studies. In study 1 (validation & cross-drug cue effects), researchers validated a set of realistic cannabis images among a sample of participants residing in the …

Gender Differences In College Drinkers: The Role Of Masculine Norms, Jared A. Davis

USF Tampa Graduate Theses and Dissertations

Drinking among college students has remained a prominent problem within the United States, with more than 50% of college students drinking alcohol, 30% considered binge drinkers, and 9% considered heavy drinkers (SAMHSA, 2018). Evidence also shows that males are more likely to partake in risky drinking behaviors (e.g., binge drinking or drinking to intoxication) and are at higher risk to be diagnosed with a alcohol use disorder when compared to women (Iwamoto et al. 2014; Grant et al., 2004). Recent findings suggest that adherence to particular masculine norms as a risk factor for problematic alcohol use among men (Mahalik, 2000; …

USF Tampa Graduate Theses and Dissertations

Secondary metabolites produced primarily by terrestrial plants and animals have provided the basis for treatments and cures of human diseases as far back as historians have been able to probe. However, recent technological advances including the self-contained underwater breathing apparatus, and even further remotely operated vehicles, have allowed researchers a unique opportunity for targeted collection of marine organisms at depths previously thought to possess conditions unsustainable for life as was understood. This has afforded a glimpse into the potential for not only life, but the potential for new biochemical adaptations developed over billions of years that have been evolutionarily developed …

Joint Models For Repeated Measured, Non-Normally Distributed Multilevel Data, Weiwei He

USF Tampa Graduate Theses and Dissertations

Clinical trials have tended to collect both survival information and longitudinal biomarkers, as well as other covariates. In order to better assess the severity of diverse diseases, we need to collect various longitudinal outcomes. Furthermore, longitudinal data could consist of a number of different measurements of varying types. The multilevel item response theory (MLIRT) model has been widely used in several fields such as public health and health sciences for multivariate longitudinal outcomes. Joint models combining the longitudinal and survival processes, as well as the relation between them, have been developed to minimize bias and improve the efficiency of estimates. …
