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 …

Classifying Emotions With Eeg And Peripheral Physiological Data Using 1d Convolutional Long Short-Term Memory Neural Network, Rupal Agarwal

USF Tampa Graduate Theses and Dissertations

Recognizing emotions is very important while building robust and interactive Affective Brain-Computer Interfaces as it allows the machines to have some degree of emotional intelligence with the help of which they can understand the changing emotional state of users. In the past, emotions have been recognized via unimodal data such as electroencephalography (EEG) signals, speech, facial expressions or peripheral physiological signals. However, emotions are complex as they are a combination of human behavior, thinking and feeling. Therefore, as compared to unimodal methods, multi-modal techniques, recognize emotions with more reliability. This thesis aims to recognize and classify human emotions into high/low …

People With Parkinson’S And Care Partners Of Pwps’ Uncertainty Management Through Information Strategies, Amy Haywood

USF Tampa Graduate Theses and Dissertations

This thesis explores how people with Parkinson’s (PwP) and care partners of PwP manage the uncertainty surrounding Parkinson’s disease (PD). PD causes both motor and cognitive decline in patients, which may affect each individual differently (Williamson, Simpson, & Murray, 2008). There is no-known cure or cause for PD, meaning it is shrouded in uncertainty from the first symptom to the ongoing management process. This disease also affects care partners because of its variability in symptoms and progression. For this reason, this research, which is part of a larger study, interviewed both care partners of PwP (n= 10) and those diagnosed …

Adolescent Asthma And School Disparities: An Ecological Perspective Of Students And Stakeholders, Tali Schneider

USF Tampa Graduate Theses and Dissertations

Asthma is a chronic condition that mainly affects adolescents. Recent reports from the Centers for Disease Control and Prevention (CDC) indicate a gradual increase in rates of lifetime asthma among adolescents from 17.1% in 2005 to 22.8% in 2015. Currently, one in ten adolescents nation-wide experience active asthma; similar trends are seen in the state of Florida (Florida Asthma Program, 2013; Centers for Disease Control and Prevention, Prevention, 2015). As a chronic, lifelong condition, asthma can be life-threatening if not properly controlled. When exacerbated, attacks of asthma constrict airways, leading to restrained breathing, wheezing, coughing and chest pain (Parulekar, Alobaidy, …

Affect And Craving: Examining The Differential Influences Of Positive And Negative Affect On Inclinations To Approach And Avoid Alcohol Use, Jacob A. Levine

USF Tampa Graduate Theses and Dissertations

Most research examining the role of affect in the etiology of alcohol craving has been limited to associations between negative affect and the desire to consume alcohol. This narrow focus has not only ignored the potential influence of positive affect on the desire to use alcohol, but has led to a failure to consider both desires to avoid using alcohol and motivational conflicts often thought to be present in alcohol use disorders (AUDs). Additionally, research investigating the influence of affect on attentional bias in favor of alcohol cues in individuals who have an AUD has been limited. Using 60 individuals …

The Effect Of Acute Interpersonal Racial Discrimination On Smoking Motivation And Behavior Among Black Smokers, Patricia F. Calixte-Civil

USF Tampa Graduate Theses and Dissertations

In comparison to White smokers, Black smokers are more likely to report both discrimination and less success in smoking cessation. No previous study has tested the causal relationship between actual experienced racial discrimination and smoking variables associated with cessation. The goal of this study was to test the casual influence of interpersonal racial discrimination on smoking motivation (i.e., the urge to smoke cigarettes, cessation self-efficacy, and smoking behavior) using a controlled experimental design. We used a virtual ball-playing game to create a laboratory model of racial discrimination. A 2x2 between-subjects factorial design (inclusion/exclusion vs. ingroup/outgroup) was used to randomly assign …

Gabbing While Gaming: Commandeering Commercial, Off-The-Shelf (Cots) Video Games To Structure Student-Centered Social Studies Discussion, Joshua M. Patterson

USF Tampa Graduate Theses and Dissertations

Amidst the current cultural backdrop of debilitating digital addiction and malicious misinformation campaigns, secondary social studies instructors require every possible tool to engage students stuck in the haze of simulated reality. While nationwide mastery of the subject area is wedged between failure (National Assessment of Educational Progress, 2020) and apathy, three-dimensional, entertainment-driven simulations are progressing at an exponential rate of adolescent adoption and historical accuracy. In this phenomenological case study, I capitalize on pupils’ preference for virtual integration by outlining a pedagogical approach that harnesses the trinity of content knowledge, discursive prowess, and video game aptitude. Video game titles were …

Perfectionism, Negative Life Events, And Cognitive Appraisal: A Contextual Model Of Perfectionism’S Maladaptive Nature, Ansley M. Bender

USF Tampa Graduate Theses and Dissertations

Perfectionism is highly (Grzegorek, Slaney, Franze, & Rice, 2004; Rice, Ashby, & Gilman, 2011) and increasingly (Curran & Hill, 2017) prevalent. Alarmingly, perfectionism is associated with various concerning correlates and outcomes, including suicide ideation and attempts (e.g. Smith, Sherry, et al., 2018). Whereas it is clear that perfectionism presents as a vulnerability for suicide, very little is known about when its maladaptive features may be particularly activated or by what pathway such a relationship exists. A preliminary, but underdeveloped, area of research suggests a role for negative life events in potentiating the effects of perfectionism, operating under the assumption that …

Disrupting The Heteronormative Mindset In Teacher Preparation Through Inclusive Children's Literature, Denise I. Donahue

USF Tampa Graduate Theses and Dissertations

Because of discrimination that presents itself through bullying based on identity, and the lack of positive LGBTQIA+ representation within classroom lessons, there is a need for a higher quality of preparation for teachers in order to create inclusive environments.

All teachers, particularly new teachers, need to know how to effectively work with diverse learners to meet their needs academically, emotionally and socially. This includes preparing teachers to instruct students and work with families who include LGBTQIA+ members. LGBTQIA+ students are often marginalized, discounted, harassed or invisible. (Kosciw, Greytak, Zongrone, Clark, & Truong, 2018). There is a need for a higher …

A Method To Analyze Similarities Of Eye Movements: A Giscience Based Spatiotemporal Approach, Mehrdad Vaziri

USF Tampa Graduate Theses and Dissertations

Similarity analysis is the subject of several studies that primarily collect, process, and analyze movement data of various types, including animals, humans, vehicles, hurricanes, and eye tracking. The movement studies often focus on characteristics of a mobile entity (moving object) over time and space. Such studies usually are interested in tracking the changes to the moving object. Therefore, the size of the object becomes irrelevant. Each mobile object is considered a moving point through time and space. The points have all two attributes in common which are locations and timestamp of those locations. Despite the similarities between the movement datasets, …

Game-Based Science Education: Effect Of Aesthetics On Learning And Motivational Outcomes, Lucille Moon-Michel

Identifying Employees Who Fit With Electronic Communication Styles, Britany Telford Mills

USF Tampa Graduate Theses and Dissertations

Electronic communication is no longer solely used by globally dispersed work teams. It is an integral part of today’s organizations whether they include remote workers or not. Therefore, it is important to understand how employees perceive electronic communication from their supervisor and the impact that perception has on the worker. Researchers have been adamant in the assertion that relationship-oriented communicated is better conducted face-to-face. The current study seeks to add to the existing body of research by (1) examining how the proportion of relationship-oriented communication that is electronic affects both subordinate perceptions of communication openness and subordinate job satisfaction, and …

Despite the consistent reduction in morbidity and mortality associated with cardiovascular disease (CVD) over the last four decades, CVD remains the leading cause of death globally. In the United States, Blacks are disproportionately affected by CVD compared to Whites. Blacks are also more likely to report incidence of perceived discrimination. Perceived discrimination has been linked to cardiovascular risk factors such as smoking, hypertension (HTN), hyperlipidemia, and obesity. However, the relationship between perceived discrimination and cardiovascular outcomes such as stroke, myocardial infarction, acute ischemic syndrome, coronary revascularization, and cardiac death remains unclear. The primary goal of this study was to examine …

Relationship Between Membership In Honors College And Participation In High-Impact Activities And Perceived Gains, Clara H. Ohannes

USF Tampa Graduate Theses and Dissertations

This research study investigated the relationship between membership in the Honors College and senior-level students’ self-reported involvement in high-impact educational activities and their perceived gains from their college experience. This quantitative study analyzed secondary data from the National Survey of Student Engagement (NSSE) collected from senior-level students in Spring 2017 at a large, four-year, public research institution in the southeast United States.

A logistic regression analysis was used to explore the relationships between the involvement in high-impact educational activities and Honors College membership. The relationship between Honors College membership and several high-impact activities were found to be significant (p<.05), which included participation in a leadership role, study abroad, research with faculty and a senior capstone experience. Since membership in Honors was found to significantly contribute to participation in four out of the six high-impact practices listed in NSSE, it could be said that generally, at the particular institution in this study, Honors students are more likely than Non-Honors students to participate in high-impact learning activities.

Then, …

Teachers And Administrators Explain How And Why Teachers Change Instructional Methods In A Pre-K Through Eight Catholic School, Judith A. Deeley

USF Tampa Graduate Theses and Dissertations

This qualitative exploratory study explored how and why teachers at four small Catholic schools in the state of Florida transformed by changing instructional methods to offer full integration of science, technology, religion, engineering, arts and mathematics (STREAM) approaches into learning experiences for grades pre-k through eight. There was a time up until the early 2000s that Catholic school enrollment was at capacity and did not require differentiation based upon unique student learning needs. However, students of current times reflect a higher need for educational approaches that are both differentiated and engaging.

“Teachers are required to teach more content and subjects …

Life After Graduation: Current Seniors' Perceptions Of Alumni Engagement And Their Expectations Of The Institution Once They Graduate, Jessica Burns Fugate

USF Tampa Graduate Theses and Dissertations

Alumni participation in the life of an institution is more important now than ever before as state and federal funding continue to shrink and alumni are called on for financial support and to serve as resources for current students. Institutional leaders are hard-pressed to bring in external revenue to bridge the gap as budgets shrink to successfully balance operational costs (Barr & McClellan, 2011), which is done mostly through fundraising efforts targeted toward parents of students, alumni and often current students before they graduate to establish a culture of philanthropy. This need for external revenue increases the necessity for engaged …

Health-Promoting Behaviors And Subjective Well-Being Among High School Students, Nicholas David W. Smith

Book-Sharing As A Context For Fathers And Mothers To Enhance Language Development Of Their Preschool Children, Yagmur Seven

USF Tampa Graduate Theses and Dissertations

Poor reading levels is a pervasive problem in the US. For example, two of every three eigth grade students in the US are estimated to demonstrate insufficient reading comprehension skills. Early use of decontextualized language, in which the language expressed is removed from the here and now, serves as a precursor of academic language proficiency. Starting as early as the third year of life, decontextualized language is less likely to be practiced in lower socio-economic status (SES) households. Although storybooks offer a rich context for practicing the language with young children, reading storybooks alone is not adequate to promote conversational …
