Breaking The Cycle: A Teacher And Mother’S Examination Of Multi-Tiered Systems Of Support, Jessica Hinton

USF Tampa Graduate Theses and Dissertations

The 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA) included Response to Intervention (RTI) as an option for determining eligibility for learning disabilities. However, there is no required structure to follow for RTI implementation. This lack of guidance leads to a lack of clarity in implementation at district and site levels. Many states use RTI as the primary indicator of whether a student needs special education services for a learning disability. RTI is a model for delivery of Multi-Tiered Systems of Support (MTSS). The terms RTI and MTSS are often used interchangeably. For clarity, I use MTSS-RTI to …

Improving Coral Restoration Outcomes Through Novel Molecular Applications, Matthew H. Gamache

USF Tampa Graduate Theses and Dissertations

Coral reef ecosystems are declining globally from numerous stressors, including localized pollution, disease, and marine heatwaves induced by climate change. To preserve these ecosystems, it is critical to identify corals that can withstand stressors—primarily future marine heatwaves—and prioritize them for coral restoration efforts until these stressors are mitigated. Coral responses to thermal stress can be influenced by several partners, including mutualistic microalgae and a vast prokaryotic community. Here, I use advanced molecular techniques to examine which partners (coral host, algal symbiont, and microbial communities) are associated with coral health, how they contribute to holobiont physiology, and their potential to increase …

The Ruling Relations Of Care: An Institutional Ethnography Of High-Risk Prenatal Care Experiences, Nicole L. Harris

USF Tampa Graduate Theses and Dissertations

Disrespect during pregnancy, labor, and delivery is common in the United States. The Centers for Disease Control and Prevention has estimated that approximately one in five women overall, and over 30% of Black women, report being ignored, dismissed, or verbally mistreated during their care. Public health efforts have primarily focused on individual-level interventions to improve patient-provider communication or reduce provider bias; however, these strategies have been critiqued for their limited scope and effectiveness in shifting outcomes. Instead, researchers and advocates have called for an examination of the structures that shape clinical encounters, including policies, protocols, workflows, and organizational culture. This …

Dissecting The Intrinsic And Extrinsic Regulators Of Prostate Cancer Dormancy In The Bone Microenvironment, Mostafa M. Nasr

USF Tampa Graduate Theses and Dissertations

Metastatic disease is the primary driver of cancer-related mortality. In prostate cancer (PCa), patient survival decreases dramatically once the disease spreads to distant organs, with over 80% of metastases occurring in the bone. This dissemination is often followed by a clinically silent period of tumor dormancy that can last for years, creating a critical reservoir of cells poised for lethal relapse. A significant barrier to understanding and targeting this dormant phase has been the lack of robust experimental models. This thesis first addresses this challenge by establishing a novel stress-induced model of PCa dormancy, validated across multiple murine and human …
