One Year Impact Of The Advancing Coping And Engagement (Ace) Program On Advanced Placement And International Baccalaureate Student Success, Amanda C. Moseley

USF Tampa Graduate Theses and Dissertations

Student success hinges on educational settings that feature a well-developed, comprehensive mental health support system (Hoover et al., 2019). Salient pieces of well-functioning mental health supports adhere to Multi-Tiered Systems of Support (MTSS) principles, including evidence-based practices with incremental intensity (Stoiber & Gettinger, 2015). Adolescents pursuing accelerated curricula in high school, specifically Advanced Placement courses (AP) and the International Baccalaureate Diploma Programme (IBDP), display a need for psychosocial support related to the stressors inherent to a rigorous curriculum (Suldo & Shaunessy-Dedrick, 2013b). Suldo and colleagues’ (2018) research on AP and pre-IBDP youth identified malleable predictors of success that became intervention …

The integration of the CCA and necrocapitalism afford theoretical and methodological guidance in this dissertation to help document the localocentric stories …

A Culturally Responsive And Sustaining Pre-School: Collaborative Approaches To Curriculum In An Underserved Florida Community, Dana R. Roberts

USF Tampa Graduate Theses and Dissertations

The early childhood education and childcare (ECE&C) sector in America “is a textbook example of a broken market” (Yellen, 2021) that operates as a “non-system” (Berlin, 2021). This manifests itself through the low-quality of its teaching cadre (Cassidy et al., 2019). This failure hits disadvantage families hardest (Chafouleas et al., 2016) - a reality that is particularly apparent in St. Petersburg, Florida’s Midtown neighborhoods where one out of every two children attending ECE programs are not meeting State school readiness standards (Florida OEL, 2020). In this study, I propose a culturally-responsive (Gay, 2018), culturally sustaining (Ladson-Billings, 2021c), and equity-based continuous …

Two Essays On Audit Engagement Partner Quality, Han Dai

USF Tampa Graduate Theses and Dissertations

I have two essays in my dissertation. Essay 1 examines whether and how individual audit engagement partner quality is associated with client firms’ risk factor disclosures (Items 1A and 7) in the annual reports (10-K filings). Specifically, I investigate whether engagement partner quality is associated with the tone and sentiment in the risk factor disclosures, as well as the disclosure of financial and tax-related risk factors. I find that clients with high-quality engagement partners use an overall negative tone in the narrative disclosures in Item 1A and Item 7. Further, I find that high-quality engagement partners are specifically associated with …

Acetate-Encapsulated Linolenic Acid Liposomes Reduce Sars-Cov-2 And Rsv Infection, Andrew R. Mcgill

USF Tampa Graduate Theses and Dissertations

Coronavirus disease-19 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), is an ongoing pandemic-endemic. In the United States, it remains the third leading cause of death in 2022. SARS-CoV-2, an RNA virus, has a genome prone to rapid mutation, generating variant species capable of resisting therapies and vaccination efforts. However, it has been estimated that more than 40% of SARS-CoV-2 infections may be asymptomatic, which calls into question any biological differences between the asymptomatic and afflicted groups. Additionally, Respiratory Syncytial Virus (RSV) is the most significant cause of bronchiolitis and asthma in neonates, with an increasing burden on the …

Exploratory Data-Driven Models For Water Quality: A Case Study For Tampa Bay Water, Sandra Sekyere

USF Tampa Graduate Theses and Dissertations

Water, a crucial resource for sustaining life, covers approximately 70% of the earth's surface. Nonetheless, the quality of water is deteriorating rapidly due to the rapid growth of urban areas and industries, which is a worrying trend causing harm to human health and the ecosystem. Water quality forecasting has a key role in water resources management by enabling effective pollution control, ecosystem monitoring, and decision-making.

Previously, traditional statistical models were used to forecast water quality, but they were unable to examine the non-linear relationships between water quality parameters, and they assumed that all datasets were distributed normally. This study uses …

Advances In Multiagent Systems Control: Multiplex Information Networks-Based Approaches And Beyond, Kimberly Witke

USF Tampa Graduate Theses and Dissertations

Multiagent systems control designs offer numerous advantages to increasingly complex civilian, military, and scientific tasks ranging from intelligent satellite swarm controls or autonomous traffic controls to remote triage and repair or remote wildlife observation, where the performance of a single agent is insufficient to execute the task at hand. Traditional methods in multiagent systems controls, however, have been infeasible for use in scalable, large-group formation controls.

With this in mind, the contribution of this dissertation is to bridge the gap in knowledge through both theoretical and experimental validation of multiagent systems control architectures. It addresses the challenges presented by unreliable, …

Travel And Migration Behaviors Of Migrants From Puerto Rico During Disasters, Lauren C. Carter

A Healthcare Claims Investigation Of Parasomnia Epidemiology, Associations With Attention Deficit/Hyperactivity Disorder, And Rem Sleep Behavior Disorder Correlates, Anh Thy Ha Nguyen

USF Tampa Graduate Theses and Dissertations

Parasomnias, such as sleepwalking and nightmare disorder, are abnormal behaviors and emotions emanating from sleep or wake to sleep transitions. Parasomnias can lead to significant adverse outcomes – sleepwalking can result in injuries and hospitalizations, frequent nightmares are associated with self-harm and suicidal thoughts, and rapid-eye movement (REM) sleep behavior disorder (RBD) is linked to neurodegeneration. Despite a history of fascination with abnormal sleep behaviors in the general and medical communities, epidemiologic understanding of parasomnias remains limited, in part due to their amnestic nature and presumption that they are benign childhood problems. This work used the MarketScan® Commercial Claims and …

A Qualitative Study Of Facilitators And Barriers Perceived By Black Students And Their Effect On Advanced Placement Course Enrollment In High School, Austin R. Cole

USF Tampa Graduate Theses and Dissertations

Advanced Placement (AP) classes can provide many benefits to students. The rigorous curriculum gives students an academic challenge to expand their educational abilities (The College Board, 2014). However, students of color are often underrepresented in AP participation (The College Board, 2014). Research has investigated factors among students of color that predict participation and success in AP courses, suggesting that family SES and prior academic achievement (Dixson et al., 2017; Ndura et al., 2003), and racial barriers impact students’ ability to choose to take AP courses (Jeffries & Silvernail, 2017; Walker & Pearsall, 2012).

Autonomous Professional Learning Through Practitioner Inquiry: A Study Of Growth Plan System Experiences, Daina Kelly Gaputis

USF Tampa Graduate Theses and Dissertations

The need for quality science education has long been established, but despite reform after reform, it remains a current concern. What we know as good teaching is not happening, perhaps because there is an increase in science teachers using alternative certification programs to enter the field. This lack of formal training causes teachers to have a reliance on professional learning opportunities to learn about reform-based science education. Unfortunately, traditional forms of professional learning are often inadequate, so newer professional learning designs have been established. Some of these newer designs, such as practitioner inquiry, offer teachers autonomy over how they assess …

Assessment Of Iso Heart Rate Method To Estimate Metabolic Rate, Karl Williams

USF Tampa Graduate Theses and Dissertations

Thermal equilibrium is primarily maintained by the body’s ability to dissipate internal heat generated during muscle contraction. A number of methods have been used to quantify this thermal burden such as charts and observation of workplace activities and behavior, however these have varying levels of validity. ISO 8996 defines a more accurate method of metabolic rate estimation that uses heart rate and maximal work capacity (MWC); however this requires the use of laboratory settings and equipment that are rarely available in the field. Equations such as the ACSM metabolic equation for the total energy expenditure of walking, hereafter referred to …
