Reducing Data Requirements In Polymer Science: Deep Neural Networks For Predicting Surface Tension Of Copolymer Compatibilizers, Md Mushfiqul Islam

USF Tampa Graduate Theses and Dissertations

In polymer chemistry, compatibilization involves adding a substance often a block or graft copolymerto stabilize polymer blends that would otherwise not mix well, leading to rough structures and weak me- chanical properties. Compatibilizers improve miscibility and reduce interfacial tension, which is critical for applications such as mixed-waste polymer recycling. Sequence-controlled polymers offer unique potential by combining the tunable chemistry of synthetic polymers with the precise, function-driven design of biological macromolecules, but unlike proteins, they lack large, evolution-shaped datasets to guide discovery. This research develops a deep learning framework to predict the surface tension of sequence-controlled copolymer compatibilizers across varying concentrations. …

Predator Exclusion Grids Protect Common Terns From Avian Nest Predators At Presqu’Ile Provincial Park, Lake Ontario, Jennifer M. Arnold, Stephen A. Oswald, Donald J. Tyerman, Michael J. Barker

Ontario Birds

Common Tern (Sterna hirundo) breeding populations in inland areas of North America have experienced significant declines, particularly in the Canadian waters of the lower Great Lakes. Once home to two-thirds of the Great Lakes population, Presqu’ile Provincial Park maintained only a small breeding colony of Common Terns from the 1970s to the early 2010s. In 2008, a research program was started to understand the population status of this colony. This involved close collaboration between faculty at Penn State University and Ontario Parks staff, and identified poor reproductive success at this site. Although many factors contributed to this poor reproductive success …

Loafing And Sleeping Behaviour Of Trumpeter Swans, Harry G. Lumsden, Gerry Markhoff, Gary Lane, Allan Scott

Ontario Birds

An observational study of loafing and sleeping behaviour of Trumpeter Swans was conducted in southern Ontario throughout the year in 2018 and 2019. Like other birds, these swans have the ability to close down one brain hemisphere at a time during rest, which is indicated by eye closure. We quantified rates of closure of eyes during sleeping bouts for both breeding and non-breeding swans. Single eye closure varied in frequency, duration and in terms of which hemisphere was shut down. Increasing duration of eye closure over time indicated an increased sense of security with surrounding in one mated pair. Proportion …

Seasonal And Spatial Patterns Of Avian Assemblages In The Eastern Taiwan Strait: Implications For Offshore Wind Farm Development, Mei-Ling Bai, Chia-Hsiang Huang, Yu-Yi Lien

Marine Ornithology

The eastern Taiwan Strait, a region situated along the East Asian-Australasian Flyway and currently undergoing rapid offshore wind energy development, remains poorly studied with respect to its seabird assemblages. Through intensive vessel-based transect surveys conducted between 2014 and 2021, this study documented 22,187 birds from 105 species across 10 orders and 29 families. Migratory non-seabirds accounted for 55.2% of individuals and dominated the species richness, highlighting the region's importance for migratory pathways. Seabird density was relatively low, however, consistent with trends in other tropical regions, and this pattern may also reflect both environmental degradation and methodological differences in density estimation. …

Development And Initial Validation Of An Instrument To Measure Teachers’ Socioscientific Issues Instruction Perceptions, Michael Edward Mitchell

USF Tampa Graduate Theses and Dissertations

Little is known about how high school science teachers perceive Socioscientific Issues (SSI) on a broad scale, including what factors shape their views of a pedagogical shift to adopt SSI. To address this critical gap, I constructed the Teachers’ Socioscientific Issues (SSI) Perceptions Survey (TSPS), the first instrument specifically designed and initially validated to measure teacher perceptions of SSI integration. This study presents the development and validation of the TSPS, offering robust evidence for its reliability, fairness, and construct validity.

Survey development adhered to gold-standard psychometric protocols (Bandalos, 2018; Crocker & Algina, 1986; DeVellis, 2012; McCoach et al., 2013) and …

Surveying Secondary Ela Teachers’ Engagement With Ai-Powered Tools For Classroom Assessment, Mona Alrashidi

USF Tampa Graduate Theses and Dissertations

The integration of Artificial Intelligence (AI) presents profound challenges andpossibilities for educational assessment, particularly in English Language Arts (ELA), where AI- powered tools can generate the very linguistic products traditionally used as evidence of student learning. While scholarship has primarily explored theoretical frameworks and broad perceptions, a critical gap remains in understanding how secondary ELA teachers navigate and report AI integration within formative assessment workflows. This understanding is essential: formative assessment has been recommended as a strategy to mitigate AI-related challenges by prioritizing learning processes over products. Yet empirical evidence of teachers’ practices remains limited.

Mathematics And Growth Mindset: A Systematic Review And Meta-Analysis Of Interventions At The Post-Secondary Level, Sean E. Murphy

USF Tampa Graduate Theses and Dissertations

Growth mindset interventions have been implemented in academic settings for over three decades (C. S. Dweck et al., 1995a). One academic field where growth mindset may be most needed is mathematics, as it is not unusual for a student to claim, “I’m not a math person.” Notably, no meta-analysis of mindset interventions in post-secondary mathematics classrooms existed prior to the current study. To close this gap in the literature, the present study included a systematic review and meta-analysis, drawing on two search methods: Boolean and snowballing. The results from both methods were screened using inclusion/exclusion criteria. Snowballing search was hypothesized …

A Multi-Faceted Study Of Antibiotic-Resistant, Opportunistic Pathogens In Wastewater And Environmental Water, Jeanette Calarco

USF Tampa Graduate Theses and Dissertations

More than 2.8 million infections due to antibiotic-resistant bacteria occur annually in the United States, and more than 35,000 people die as a result. Domestic wastewater (sewage), which contains antibiotic-resistant bacteria and antibiotic resistance genes, is collected at treatment plants for removal of contaminants, e.g. pathogenic microorganisms and nutrients. While wastewater treatment is designed to remove antibiotic-resistant bacteria and other microorganisms through treatment and disinfection, some bacteria may escape treatment. Treated wastewater effluent is generally discharged into surface waters; however, some fraction of the effluent may be used as recycled water. Compromised wastewater collection infrastructure and sewage spills can disseminate …

Enhancing Nitrogen Removal In High Permeability Bioretention Media: The Combined Role Of Biochar, Wood Chips And Hydraulic Design, Joshelyn Guimaray

USF Tampa Graduate Theses and Dissertations

Urban stormwater runoff can transport high nutrient loads to receiving waters, leading toeutrophication, harmful algal blooms, and the formation of hypoxic zones. Bioretention systems are a form of green infrastructure designed to mitigate these impacts, but their application in dense, ultra-urban environments is often limited by large land area requirements. This has led to the adoption of high permeability media (HPM) to accommodate higher hydraulic loading rates (HLRs) and reduce the system footprint. However, conventional HPM systems often show inconsistent removal of dissolved nitrogen species due to short hydraulic retention times (HRTs), a lack of organic carbon, and insufficient anoxic …

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 …

Cross-Linked Cellulose Ester/Linseed Oil Composites For Controlled Release Fertilizers, Ian Stark

USF Tampa Graduate Theses and Dissertations

Food scarcity is an ever-present concern for a growing population but can be mitigated through innovations in agriculture. Fertilizers are required to produce a sufficient amount of food, and while they contain key nutrients for crop growth, these nutrients can leech into the surrounding environment. Controlled release fertilizers slow the release of nutrients, encasing the prills in a semi permeable coating. Current coatings are non-biodegradable, causing microplastic soil contamination, which is very difficult to remove. Cellulose esters offer a compelling alternative, with an ability to cross-link into thin films that can be applied as coatings. The cellulose esterification was completed …

Metabolic Insights Into Cyst Fluid Composition And The Role Of Taurine In Polycystic Kidney Disease, Vineetha Garimella

USF Tampa Graduate Theses and Dissertations

Polycystic kidney disease (PKD) is the most common genetic disorder affecting kidneys and the fourth leading cause of kidney failure. It occurs in two major forms, autosomal dominant PKD (ADPKD), and autosomal recessive PKD (ARPKD). ADPKD is typically adult-onset and caused by mutations in the PKD1 and PKD2 genes, and ARPKD generally manifests in utero and is caused by mutations in the PKHD1 gene. Despite the severity of the disease, only one FDA-approved drug, tolvaptan, is currently available for ADPKD and remains under clinical investigation for ARPKD. However, its use is limited by adverse side effects including polyuria, polydipsia, and …

Ai-Assisted Spectral Fingerprinting Of Mg-Doped Zno Tracer Phosphors: Tuning Photoluminescence Emission And Investigating Lifetime Via Sol-Gel Synthesis Parameters, Thomas M. Brandte

USF Tampa Graduate Theses and Dissertations

Plastic sorting remains a major driver of recycling costs, and existing infrared (IR) optical identification systems cannot determine material prominence or quality, nor reliably identify dark polymers [1]. This work explores a PVA-stabilized sol–gel and thermal synthesis route for magnesium-doped zinc oxide (Mg:ZnO) as a tunable photoluminescent tracer phosphor.

Lattice-defect control forms the foundation of phosphorescent emission tuning, enabling unique spectral fingerprints to be generated based on synthesis parameters—Mg molar ratio (Mg%), PVA mass (g), and calcination temperature (°C). Photoluminescence (PL) spectra (400–850 nm) were analyzed using Gaussian peak fitting and principal component analysis (PCA), reducing hundreds of spectral features …
