New Developments In Space-Filling Designs, Xiankui Yang

USF Tampa Graduate Theses and Dissertations

This dissertation presents three methodological advancements to improve the construction of space-filling designs for meeting different needs of computer experiments. Traditional space-filling designs focus on achieving uniform coverage in the input space, ensuring that design points are spread evenly throughout. However, in some scientific and engineering applications, varied density of design points may be desired for more efficient data collection when prior knowledge implies different emphases. In other cases, ensuring good coverage and/or spread of the response values allows better performance of fitted models in the next stage of applications. Many processes involve variation in response values. Therefore, incorporating variation …

Unquaint Pigs’ Stakeholder Perspectives On Wild Swine In Central Western Florida, Tyler Koerner

USF Tampa Graduate Theses and Dissertations

The Anthropocene presents important questions for how to address the continuous transferal of new species into new spaces and the cascading impacts of environmental transformations. Novel ecosystems present one such outline for conservation that acknowledges the modification of historic ecosystems and the social entanglements that arrive with new species. I argue that novel ecosystems can benefit from further anthropological integrations that aid in describing the entanglements of introduced species and the pursuit of best managerial outcomes. For wild swine in Florida, the adoption of a novel approach is especially relevant because of entanglements with historic and modern Floridian stakeholders and …

How Well Are We Preparing U.S. Youth With Down Syndrome For Health Care Transition? A Mixed-Methods Study Assessing Provider Support And Exploring Caregiver Experiences, Suman Kanti Chowdhury

USF Tampa Graduate Theses and Dissertations

Background: Health care transition (HCT) preparation is a structured process that empowers youth to take ownership of their health care as they transition into adulthood. Youth with Down syndrome (DS), a common genetic disorder associated with a high burden of co-occurring conditions, require HCT preparation support at a higher rate than their typically developing peers. Although transition preparation has been examined across various chronic conditions, few studies have focused on youth with DS. Moreover, prior research was limited by methodological constraints, including the lack of a validated HCT index, a small sample size, outdated estimates, and a lack of a …

By applying transfer learning to a manually refined, locally labeled dataset of our campus, we significantly improved feature extraction for urban textures and adapted the model to our specific use case. To ensure efficient edge deployment, the network is optimized using TensorRT [1], …

Microarchitectural Vulnerabilities And Performance Tradeoffs In Shared Scientific Computing, Zyad Abd-Elrahman, Santosh Pandey

Bellini College REU Symposium (BCREUS)

Introduction & Problem Statement

Shared scientific computing platforms are built for speed and utilization, but they create a security problem that isolation alone can't fully solve. Even with TEEs, containers, or a privilege separation in place, the hardware underneath remains a shared resource. Speculative execution, cache contention, interconnect timing, and similar microarchitectural effects can leak information or create integrity risks across protection boundaries without any malicious code involved. For CI operators running graph workloads, HPC kernels, or ML pipelines in co-tenanted systems, the threat is inherent in normal execution. The real question isn't whether these vulnerabilities exist, but it's what …

Teacher Candidates’ Reflective Practices Of Mathematics Curriculum From The Lens Of Universal Design For Learning, Weichen Zhao

Journal of Practitioner Research

The Universal Design for Learning (UDL) framework encourages educators to proactively remove barriers in curriculum and instruction to increase accessibility for all learners. While UDL is often applied during lesson planning, it can also serve as a powerful tool for critically examining and revising existing mathematics curricula. Drawing on qualitative data from teacher candidates’ reflective journals and curriculum artifacts collected over two semesters, this study examines how guided reflection supported teacher candidates in identifying barriers, proposing inclusive adaptations, and deepening their understanding of equity-oriented mathematics instructional design. As a self-study grounded in participatory action research, the findings also informed the …

(Re)Imagining Research-Practice Collaboration And Partnership: Constructivism By Way Of Interdisciplinarity, Multimodality, And Humanity, Bethany Silva, Alecia Magnifico, Laura Allen, David Baroody, Ashley Barry, Shawna Coppola, Cathy Fraser, Emily Geltz, Anne Mcquade, Christina M. Ortmeier-Hooper, Laura Smith, Donna Turco

Journal of Practitioner Research

Research-Practice Partnerships (RPPs) have become an important vehicle for educational research. By connecting researchers and educators, RPPs can couple systematic research and practical application. However, relational practices for building research collaboratives are understudied, and RPPs often reinscribe power imbalances among practitioners and researchers. With its focus on the centrality of practitioners and their knowledge, practitioner research offers possibilities for disrupting such power imbalances. In this reflective essay, our team describes our efforts to harness practitioner research’s capacity to identify and address salient school-level issues and RPPs’ power to impact a wider audience. We identify practices to build relationships, inform research …

Journal of Practitioner Research

This practitioner inquiry explores how a Pacific-oriented social-emotional learning (SEL) framework, Nā Hopena A‘o (HĀ: BREATH), can affirm the cultural identities and emotional well-being of Filipino multilingual learners (MLs) in Hawai‘i. Implemented over a 15-week period in a third-grade classroom, the study draws on culturally adapted SEL lessons, student exit tickets and focus groups, and teacher reflections to examine how SEL shifts when grounded in Indigenous values, heritage language use, and community knowledge. Findings reveal three key themes: (1) Cultural Connection Fosters Belonging, (2) Language Visibility Promotes Emotional Safety, and (3) Identity-Affirming Practices Build Confidence and Voice. While students responded …

From Inquiry To Action: Leveraging Group Level Assessment To Elevate Teacher Voice, Claire C. Underwood, Leslie Kochanowski, Abraham Underhill

Journal of Practitioner Research

This methodological paper explores the use of Group Level Assessment (GLA) (Vaughn & Lohmueller, 2014; Vaughn, 2024) as a participatory approach to practitioner inquiry within an early childhood education program. Using Cochran-Smith and Lytle’s (2009) inquiry as stance as a guiding conceptual framework, GLA is framed as a methodology that affirms educator expertise, fosters collective reflection, and generates tangible action. We document the adaptation and implementation of the GLA protocol at the Arlitt Center, a university-affiliated early childhood laboratory school committed to teacher-led professional learning. Through an adapted GLA process, teaching staff engaged in identifying barriers and opportunities related to …
