The purpose of this empirical quantitative study, supported by a structured literature review, is to examine the relationships among Pre-K participation type, kindergarten readiness, and 3rd-grade literacy outcomes in order to inform district-level decisions regarding Pre-K expansion. School Readiness Theory and Emergent Literacy Theory provide the foundational groundwork for the study. School …

Sustainable Approaches For Water Remediation And Soil Amendment, Hashani Abeysinghe Herath Mudiyanselage

Theses and Dissertations

Hydrosphere decontamination and sustainable agriculture are economic, health, and environmental concerns. Conventional non-destructive and destructive water treatment methods, and fertilizer formulations, can be expensive or ineffective. Biochar-nutrient composites have gained global acceptance as adsorbents or soil additives due to biochar’s modifiable surfaces, enabling enhanced performance and environmental benefits. This dissertation studied sustainable methods for removal of aqueous arsenic(V) by adsorption and destruction of per- and polyfluoroalkyl substances (PFASs) in liquid ammonia by defluorination and fertilizing phosphorus-deficient soil. Chapter II focuses on the surface morphological and physicochemical changes in alkali-exposed microparticulate magnetite-deposited rice husk (RH) biochar (Fe3O4@RHBC) relative to its pristine …

Analyzing The Relationship Between Financial And Real Estate Investment And Agricultural Land Values., Hudu Abukari

Theses and Dissertations

Using agricultural transaction data from 2019 to the first quarter of 2023 provided by a major financial lender in Mississippi, I assess the relationship between financial and real estate buyers and agricultural land prices. Grantor and grantee information in the data allowed me to classify buyers into individuals, non-individual agribusinesses, and financial and real estate buyers. A hedonic pricing model is used to explore the relationship. The study concluded that the buyer type of agricultural land matters. More specifically, financial and real estate buyers pay a premium more than individuals and agribusiness buyers.

Optimization Of Punicalagin-Releasing In Situ Forming Microparticles (Prism) For Treatment Of Osteoarthritis, J. Alejandra Amaya

Theses and Dissertations

Theses and Dissertations

Uncrewed aerial application systems (UAAS) are increasingly used for agricultural spraying, but spray deposition uniformity and effective swath width can vary between platforms. This study evaluated spray-pattern deposition and effective swath width for two commercial off-the-shelf (COTS) UAAS platforms during manual and autonomous flight operations. Manual, single-pass testing was used to assess preliminary performance and spray characteristics for both UAAS. Further autonomous multi-pass and single-pass evaluations were conducted to assess deposition uniformity and in-swath variability for both UAAS utilizing two methods of evaluation: Operation Self-regulating Application & Flight Efficiency (S.A.F.E.) pattern testing for manual flight evaluation and the Swath Gobbler …

They Not For Us: Reimagining Social-Emotional Learning For Black Youth, Jennifer Chinecherem Ani

Theses and Dissertations

Social-emotional learning (SEL) interventions are often implemented within a Positive Behavioral Interventions and Supports framework and have been found to be effective in improving students’ social, emotional, behavioral, and academic outcomes. However, SEL interventions are typically implemented as a Tier I intervention and there is limited research on SEL interventions implemented in Tier II. Additionally, SEL interventions have received criticism for not being culturally relevant for minoritized populations, especially Black students. This study aims to seeks to extend the current literature on making cultural adaptations of an SEL intervention, specifically for Black elementary students using the Ecological Validity Model (EVM). …

Theses and Dissertations

Alternative and sustainable sources of energy have become critical in the 21st century due to strains on energy supply because of rising global populations and increasing global temperatures driven by fossil fuel extraction and use. One promising source is woody biomass, which has the advantage of being both abundantly available and readily accessible. Short rotation woody crops (SRWCs) have been widely researched for their ability to produce biomass in shorter periods compared to other traditional woody biomass crops and providing a constant supply to meet demands. However, currently there is a lack of standards for optimally establishing and growing SRWC …

An Evaluation Of Three Remote-Sensing Technologies Applied To French Colonial Fort St. Pierre, Mariah Gonzales

Theses and Dissertations

This research is focused on the eighteenth century French Colonial Fort St. Pierre located in the Lower Mississippi Valley. Fort St. Pierre stood from 1719 to 1729 before being destroyed as a result of the Natchez revolt. With such a short existence, this fort has not been the subject of much research. With no archaeological features on the surface, the site was chosen to employ three remote-sensing methods to build the first digital rendering of the site and to measure the efficacy of each method in archaeological investigations. This study used LiDAR, Ground Penetrating Radar, and Magnetic Gradiometry to identify …

Examining Bark Water Storage As A Function Of Morphology And Subsequent Impacts On Stemflow Yield In A Mixed Hardwood Stand, Max Arnold

Theses and Dissertations

Forest canopy partitioning influences the movement and redistribution of precipitation, with bark serving as a critical interface regulating water storage and stemflow yield. This study quantified bark morphological and hydrological traits across six common southeastern United States tree species and evaluated their influence on stemflow yield. Significant interspecific differences were observed in bark thickness, bulk density, total porosity, bark water storage capacity (BWSC), and absolute hygroscopicity. Bulk density was positively related to BWSC and absolute hygroscopicity, whereas total porosity was negatively related to both traits. Despite substantial variation in bark properties, none of the measured bark traits consistently predicted stemflow …

A Comparative Study Of Synthetic Aperture Radar Focus Algorithms For Maritime Surveillance Applications, Madison M. Forrest

Theses and Dissertations

Maritime Synthetic Aperture Radar (SAR) imagery is frequently degraded by vessel motion and ocean-induced dynamics that violate the stationary scene assumptions of conventional SAR image formation, resulting in azimuth defocus and reduced image interpretability. Autofocus techniques are commonly employed to mitigate these effects; however, their relative performance in maritime environments and the tradeoffs between image quality and computational complexity remain areas of ongoing investigation. This work presents a comparative evaluation of three established SAR autofocus algorithms—Phase Gradient Autofocus (PGA), Minimum Entropy (ME), and the Doppler Parameter Estimation Algorithm (DPEA)—applied to real-world maritime SAR imagery. The study utilizes X-band SAR data …

A Study On The Welfare And Crop-Residue Ameliorating Potential Of Acheta Domesticus In The Context Of Insect Sequestration, Metabolism, And Excretion Of Three Mycotoxins: Aflatoxin B1, Deoxynivalenol, And Zearalenone, Ryan Thomas Paulk

Theses and Dissertations

Mycotoxins are a food security issue that affects all crops globally, but to varying degrees, due to the ubiquity of fungi that produce them. Developing new agricultural practices that can ameliorate lost nutrients post-contamination by removing mycotoxins for the next levels in the food chain can remedy an inevitable effluent in the circular economy. Farmed insects, such as the house cricket, Acheta domesticus, can potentially consume moldy, mycotoxin contaminated grains safely without transferring them to other trophic levels. The experiments herein test the biology of A. domesticus to consume three individual mycotoxins: aflatoxin B1, deoxynivalenol, and zearalenone. In addition to …

Elementary Preservice Teachers’ Use Of Representations To Compare Fractions In Area, Length, And Set Contexts, Sarah Salisbury

Theses and Dissertations

Mathematics teachers’ knowledge of rational numbers is very important due to the prominence of fraction concepts across the K-12 curriculum. Preservice teachers (PSTs) typically only have a procedural understanding of fractions and lack conceptual understanding (Newton, 2008). PSTs struggle to construct pedagogical representations that correctly show the size of parts and wholes (Lee & Lee, 2019). The purpose of this study was to investigate PSTs’ ability to compare fractions by examining their selection and creation of appropriate and accurate fraction representations in context, including the use of area, length, and set representations. The purpose was also to determine the extent …

Development And Comparison Of Retained Ownership Decision Methodologies For Feeder Cattle Owners, William John Simmons

Theses and Dissertations

Cattle producers retain ownership through the feeding phase in the hopes of increasing profits. Because not all cattle generate positive profits, retention decisions on an individual basis substantially affect overall profitability. This study develops, simulates, and evaluates among others a new prediction methodology intended to help improve profitability. The method is an integrated framework combining a novel multilevel (hierarchical) growth model, futures basis-adjusted price forecasting, and production cost estimation to predict which animals are expected to be profitable. Individual performance data were collected for 12,066 in-sample (2003 to 2011) to predict growth and profits for 12,496 out-of-sample cattle (2011 to …

Toward Secure Genomic Intelligence: Privacy-Preserving Deep Learning Frameworks For Cancer Classification And Collaborative Analysis, Yibo Dong

Theses and Dissertations

Genomic data contains highly sensitive personal information, yet cancer classification and collaborative medical research increasingly depend on sharing such data across institutions. Existing privacy-preserving approaches for deep learning, including differential privacy (DP) and standard federated learning (FL), leave critical vulnerabilities: DP degrades model utility through noise injection, while FL relies on a trusted aggregation server that remains susceptible to gradient-based attacks. This dissertation develops, evaluates, and optimizes a series of privacy-preserving deep learning frameworks specifically designed for genomic cancer classification. First, a systematic benchmarking study evaluates DP, FL, and fully homomorphic encryption (FHE) across three deep learning architectures (fully connected …

The Fate Of Duplicate Meiotic Recombination Genes After Whole Genome Duplication In Vertebrate And Yeast Lineages, Sophie Maedo

Theses and Dissertations

Meiotic recombination is the exchange of DNA between homologous chromosomes that creates novel allele combinations and therefore aids in evolution. After whole genome duplications (WGD), challenges arise with proper chromosome segregation, necessitating changes to the meiotic recombination pathway. Reducing recombination rate and recombination gene copy number are mechanisms to correct multivalent formation. Within plants, copy number and retention rate of these genes has been well characterized; however, this is untrue for the wider eukaryote domain. Through this work, I show that meiotic recombination genes are maintained at a lower copy number than the rest of the genome; however, immediately after …

Impact Of In-Season Potassium Fertilizer Application On Sweetpotato Yields, Alyssa Lynn Hotchkiss

Theses and Dissertations

Sweetpotatoes require approximately three times more potassium (K) than nitrogen (N), making K the most applied nutrient in production. However, K fertilizer recommendations for sweetpotatoes in Mississippi remain outdated or are based on recommendations for other crops. This study evaluated the effects of K fertilizer rate, timing, and application method on sweetpotato production. Field trials were conducted during the 2023 and 2024 growing seasons at the Pontotoc Ridge-Flatwoods Branch Experiment Station in Pontotoc, Mississippi. Treatments included preplant K applications of 0, 134, or 191 kg ha⁻¹ K₂O, in-season sidedress applications of 56 kg ha⁻¹ K₂O, and four foliar K treatments. …

Palmer Amaranth (Amaranthus Palmeri) Seedbank Decay And Susceptibility To S-Metolachlor And Glufosinate In Mississippi, Nestor Cordero

Theses and Dissertations

Palmer amaranth (Amaranthus palmeri S. Watson) is one of the most troublesome herbicide-resistant weeds in U.S. agriculture. This study evaluated (1) seed persistence across soils collected from major row-crop production areas in Mississippi by investigating the influence of soil physicochemical and microbial properties on seed viability and (2) the prevalence of resistance to S-metolachlor and glufosinate among Mississippi populations. A seed burial experiment using soils from 57 locations representing 10 counties showed that seed viability declined substantially between 4 and 6 months after burial. Although soil physicochemical properties were associated with variation in seed viability, no single factor consistently explained …

Profiles Of Body Image In Emerging Adults And Associations Across Sociocultural Influences, Alligrace Story

Theses and Dissertations

The Tripartite Influence Model of body image suggests that multiple sources of appearance-related pressures (i.e., family, peers, significant others, and media) impact body image and disordered eating behaviors via appearance-related comparisons and internalization of body-related ideals (i.e., thin-ideal internalization and muscular-ideal internalization). Previous research has shown support for the Tripartite Influence Model of body image among various demographic groups. The current study identified and examined profiles of emerging adults based on their reported body esteem and body appreciation. Body esteem was measured using the Body Esteem Scale for Adolescents and Adults (BESAA; Mendelson et al., 2001), and body appreciation was …
