Standardizing Gestational Diabetes Mellitus Education To Improve Patient Knowledge And Care Consistency In A Prenatal Clinic Setting, Wynn Zara
Master's Projects and Capstones
The gestational diabetes mellitus (GDM) group visit framework aims to improve consistency of GDM education by standardizing referral processes, educational materials, staff workflows, and patient communication. Although evidence-based GDM education supports patient self-management and improved maternal-fetal outcomes, variability in education delivery contributed to inconsistent care within the outpatient maternal-fetal medicine setting. This quality improvement project was conducted in an outpatient maternal-fetal medicine clinic in Santa Clara County serving pregnant patients diagnosed with GDM. To address this gap, a standardized GDM group visit framework was developed and implemented using structured educational resources, referral criteria, and communication workflows. The intervention was evaluated …

Staffing Reductions, Visitor Sentiment, And Recreation Demand In U.S. National Parks, Rebekkah Adicoff
Theses and Dissertations
Staffing changes in U.S. national parks have the potential to influence both visitor experience and recreation demand. This study examines how an abrupt system-wide staffing reduction affected visitor sentiment and visitation across the National Park System, while accounting for differences in park-level risk exposure. Using the February 2025 staffing reduction as a quasi-natural experiment, the analysis combines monthly park-level visitation data with TripAdvisor visitor reviews from January 2024 to August 2025. Sentiment scores derived from reviews measure perceived experience quality, while recreation demand is modeled using fixed-effects count models (Poisson and negative binomial) that control for seasonality and park characteristics. …
Impact Of In-Season Potassium Fertilizer Application On Sweetpotato Yields, Alyssa Lynn Hotchkiss
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 However, K fertilizer recommendations for sweetpotatoes in Mississippi remain outdated or are based on recommendations for other crops.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. …

Analyzing The Relationship Between Financial And Real Estate Investment And Agricultural Land Values., Hudu Abukari
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.
Profiles Of Body Image In Emerging Adults And Associations Across Sociocultural Influences, Alligrace Story
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 …
Designing A Measure Of County-Level Food Access, Logan Mattingly
Designing A Measure Of County-Level Food Access, Logan Mattingly
Theses and Dissertations
Equitable access to food is a central component of food security and a key determinant of health. Yet current approaches to food access measurement remain fragmented and limited. This study introduces the first of its kind data driven, multidimensional, county-level measure of food access in the United States. Drawing on publicly available data, I employ a factor analysis pipeline to construct a suite of latent variable estimates that represent pillars of food access. This model-based approach allows synthesis of these diverse measures into the resulting Food Access Index (FAI), while explicitly accounting for measurement error and addressing missing data. Resulting …

Directed by this theoretical framework, the study addressed three research questions: (1) How do selected districts design …
Ethnic Identity And Career Adaptability Among African American High School Students: Exploring The Roles Of Perceived Barriers And Social Support, Zion J. Kamau
Theses and Dissertations
African Americans are subjected to systemic racial discrimination and bias in the labor market. Data on labor force participation collected by the U.S. Census Bureau between 1970 and 2010 were investigated for the purpose of identifying trends, and it was found that race and ethnicity significantly influence an individual's labor market position and employment outcomes (Byars-Winston et al., 2014). African Americans were more likely to hold positions earning less, requiring fewer skills, and associated with a lower social status. There is a misconception that the phenomenon occurs only in adulthood, but it is also observed during adolescence. The U.S. Bureau …
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 …
Development And Comparison Of Retained Ownership Decision Methodologies For Feeder Cattle Owners, William John Simmons
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 …

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). …

Examining The Effects Of Oral Melatonin Supplementation On Bull Reproductive Physiology, Megan M. Patterson
Theses and Dissertations
Bull subfertility is a prevalent issue with significant consequences for cattle production. Unfortunately, few management interventions exist to alleviate bull subfertility and improve bull reproductive efficiency. Melatonin, a key regulator of circadian rhythms and seasonal reproduction, improves reproduction in non-seasonally breeding mammals, yet the benefits of oral supplementation in the bull remain underexplored. Therefore, this study aims to elucidate the extent to which melatonin supplementation could serve as a management intervention to improve bull reproductive efficiency. Yearling Angus bulls (n = 21) were utilized to examine the effects of 90 days of oral melatonin supplementation on sperm quality, blood plasma …

The Role Of Latinx And Hispanic Identity In The Presentation Of Hoarding Symptoms, Caitlyn Ashley Nix
The Role Of Latinx And Hispanic Identity In The Presentation Of Hoarding Symptoms, Caitlyn Ashley Nix
Theses and Dissertations
Although people who identify as Hispanic and Latinx make up approximately 19% of the United States population (U.S. Census Bureau, 2023), most research into hoarding disorder is comprised of White, non-Latinx samples. Thus, the current study investigated Hispanic and Latinx ethnicity as a predictor of several facets of hoarding disorder. Previous literature has shown lower risk for Hispanic and Latinx individuals in terms of several physical health outcomes when compared to individuals of similar socioeconomic status (Markides & Coreil, 1986), though mental health outcomes have more variation by subgroup (Barragán et al., 2020). Previous research has also shown that collectivistic …
An Equity-Centered Creative Therapies Implementation Framework For K-12 School Counseling Practice, Brian Caleb Carlisle
An Equity-Centered Creative Therapies Implementation Framework For K-12 School Counseling Practice, Brian Caleb Carlisle
Theses and Dissertations
Adolescents in K-12 schools are experiencing a significant mental health crisis, with rising rates of anxiety, depression, trauma, and emotional dysregulation, while many continue to face limited access to equitable, developmentally appropriate supports. Although schools increasingly serve as primary sites for mental health services, they often lack resources, training, and infrastructures necessary to implement effective interventions. Arts-based and creative therapy approaches demonstrate benefits for emotional regulation, trauma processing, and social-emotional development but remain underused due to inconsistent implementation and systemic barriers. This capstone project examines how creative therapies can be integrated into school counseling programs to address these gaps. Guided …

Enhancing Social Emotional Learning Interventions For Black Adolescent Girls Through Staff Training, Shundrell Mcmullan
Theses and Dissertations
Black girls often face systemic inequities rooted in discriminatory practices and policies in the educational system contributing to adverse social-emotional outcomes unless mitigated by intentional protective supports. Many schools have adopted social emotional learning (SEL) programs; however, their effectiveness for culturally diverse students are often challenged. The present study examined the impact of Sisters of Nia, a race-conscious and gender-responsive intervention designed to enhance protective factors and social-emotional well-being among six adolescent Black girls. Student outcomes, including academically engaged behaviors and positive peer interactions, were primarily evaluated using a single-subject A/B design. Students’ self-esteem and racial identity were also measured …
Scan Statistics For Nonhomogeneous Poisson Processes: A Method For Cnv Detection, Asanka Rathnayaka Duwage
Scan Statistics For Nonhomogeneous Poisson Processes: A Method For Cnv Detection, Asanka Rathnayaka Duwage
Theses and Dissertations
This dissertation studies scan statistics for detecting localized changes in non-homogeneous Poisson processes. The motivating problem arises from genomic sequencing data, where tumor and normal read locations may differ over short regions due to copy number variation, while the underlying event intensity varies across the domain. In this setting, methods based on homogeneous Poisson process assumptions are not appropriate. The dissertation develops and studies scan-based methods for detecting local differences while accounting for non-homogeneous structure. Three related approaches are considered. The first develops a scan statistic for a nonhomogeneous Poisson process and uses extreme value calibration after transformation under the …
