Use Of Wetlands By Migratory Waterbirds In The Lower Mississippi Alluvial Valley, Duncan Fraser

Theses and Dissertations

The Lower Mississippi Alluvial Valley (LMAV) is a critical stopover and wintering area for dozens of migratory waterbird species. For many species, especially shorebirds, shallow water and mudflats during migration and winter are vital for foraging and survival. Wetland restoration combined with strategic flooding practices can provide important resources for various waterbird guilds using the LMAV. I surveyed waterbirds during three migration seasons (January-May 2024 and 2025, and July-December 2024) across 62 total wetland units on four national wildlife refuges, four wildlife management areas, and one aquaculture facility in the Mississippi LMAV. I also compared abundance and richness of waterbirds …

Considerations For Cottonseed Oil As A Feedstock For Renewable Fuels, John Elmore

Theses and Dissertations

As the world population grows and the standard of living improves in developing countries, global energy demand will continue to rise, with energy use in the developing world expected to increase dramatically more than the per capita reductions in developed countries from efficiency improvements. Nearly a third of the total global energy demand is used for transportation, resulting in a substantial contribution to greenhouse gas (GHG) emissions. While the demand for energy rises, initiatives and regulations are underway to mitigate the amount of GHG emissions to Earth’s atmosphere. As efforts progress in industry, governments, and society to reduce the total …

Impacts Of Upgrading Gcc On The Srtuner Compiler Autotuning Algorithm, Jonathan D. Butterfield

Theses and Dissertations

An often-overlooked research gap is the applicability of research over time. The impact of updating the GNU Compiler Collection version was investigated for the SRTuner compiler optimization research. Versions 7 through 14 were tested using documented flags and recommended flag dependencies. Quality controls measured and enforced consistency across test runs and benchmarks. The performance of SRTuner was compared to a random control while the impact of enforcing flag dependencies was evaluated. The most influential flags were investigated by turning them off in isolation, but results were mixed. It was determined that enforcing flag dependencies resulted in improved performance, but the …

Responding To The Urban Canvas: Murals, Preservation, And Placemaking In Meridian, Ms, Katy Kemalyan

Theses and Dissertations

Public murals that depict elements of local culture and history are a creative placemaking tool increasingly used by preservationists invested in the revitalization of their historic districts. As this trend rises, it becomes necessary for preservationists to ask what should be painted, restored, or left alone? Research on public murals neglects Southern mid-sized towns, considerations of existing murals, and historic architecture used as substrates. Rectifying this omission and employing geographic surveys and stakeholder interviews, this study seeks to expand which genres of murals are considered for their creative placemaking value. Normally distinguished primarily by source in literature, community murals, ghost …

The Biology Of Green Antelopehorn Milkweed (Asclepias Viridis Walter) And Hemp Dogbane (Apocynum Cannabinum L.) And Response To Triclopyr Formulations And Other Auxin Herbicides, Kayla L. Broster

Theses and Dissertations

Studies were conducted in Oktibbeha and Clay Counties in Mississippi to determine the response of green antelopehorn milkweed and hemp dogbane to triclopyr and other auxin herbicides in non-cropland areas. These studies were conducted at four locations with well established populations for each species throughout 2020 to 2023, with applications repeated at each location the following year if populations persisted. Treatments included a high and low rate of each herbicide studied, with all four triclopyr formulations included for both species. Injury response data were collected two and four weeks after treatment and population density data were evaluated using individual stem …

Equity By Design: A North Glenn High School Equitable Practices Policy Guide, Kelli Andrews Jarrett

Theses and Dissertations

This capstone project addresses equity gaps in dual enrollment programs in Mississippi, with a focus on North Glenn High School, a pseudonym for a high-poverty rural school. While dual credit opportunities have expanded statewide, disparities remain for first-generation, low-income, and minority students. A significant barrier is Mississippi’s reliance on ACT benchmarks for eligibility, which disproportionately excludes marginalized groups. The study examines the potential of the Pre-ACT in grades 9 and 10 as an early diagnostic tool to identify readiness gaps and inform targeted interventions before students take the ACT. Grounded in Bronfenbrenner’s Ecological Systems Theory and the Dual Enrollment Equity …

Spatiotemporal Ecology Of Mycobacterium Ulcerans And Mycolactone Functions In French Guiana And Southeastern United States Aquatic Environments, Magdalene Dogbe

Theses and Dissertations

Mycobacterium ulcerans, the causative agent of Buruli ulcer, produces mycolactone, a polyketide toxin traditionally studied for its role in human pathogenesis. This dissertation presents a comprehensive spatiotemporal analysis of M. ulcerans and mycolactone producing mycobacteria (MPM) ecology in the Americas and also reveals mycolactone's role in the environment as a microbial community regulator. Through comparative studies in French Guiana (endemic) and the southeastern United States (non-endemic), combined with experimental microcosm investigations, this research contributes to environmental pathogen ecology understanding. Environmental surveillance across 2,226 samples from French Guiana revealed complete MPM restriction to freshwater environments, with zero detections from 1,226 coastal …

Small Area Estimation Methods For County-Level Forest Biomass Estimation, Pratyush Dhungana

Theses and Dissertations

We evaluated small area estimation (SAE) methods for county-level forest biomass across four Forest Inventory and Analysis (FIA) regions in the contiguous United States using the coefficient of variation and relative root mean squared error. The Standard Fay–Herriot (FH) model was compared with multivariate, spatial, and measurement-error extensions, while the unit-level Battese–Harter–Fuller (BHF) model was compared with mixed-effects random forests (MERF) with auxiliary data from remote sensing. Spatial FH improved precision when spatial dependence was strong; otherwise, Standard FH was more reliable. All FH models were effective with fewer than 100 plots. Measurement-Error FH produced more accurate estimates than FIA …

Advancing Equity In Adolescent Mental Health: A Literature Review And Telehealth Program Design For School-Based Access, Renatta Lindsey

Theses and Dissertations

Adolescents in the United States (U.S.) are experiencing a mental health crisis, with disproportionately high prevalence rates among marginalized youth. Approximately 1 in 5 adolescents are diagnosed with a mental, emotional, or behavioral condition (Panchal, 2024; Sappenfield et al., 2024). Yet, an estimated 40% (1.8 million) of adolescents aged 12-17 who experience a major depressive episode did not receive treatment (Substance Abuse and Mental Health Service Administration, 2024). This project examines existing barriers that hinder access to care for this population. While schools are the most common settings for adolescent mental health supports, more than half report difficulties with meeting …

Study On Vehicle-Pedestrian Interaction Autonomy By Risk Potential Theory, Riku Kikuta

Theses and Dissertations

Vehicle–pedestrian interaction is a critical aspect of autonomous vehicle (AV) development, as socially acceptable AVs must account for pedestrian intention and behavior. Risk Potential (RP) theory provides a framework to build human-like AVs by modeling expert driver risk perception, but conventional RP models treat pedestrians as static obstacles and neglect their dynamics. This dissertation extends RP theory by incorporating pedestrian velocity and orientation into three new models: the RP velocity model, the RP related-velocity model, and the RP Pedestrian Potential Position (PPP) model. These models were implemented in the Navigating All Terrains Using Robotic Exploration (NATURE) autonomy stack and tested …

Space Utilization Optimization, Troy D. Rockwood

Theses and Dissertations

Outer space is a crucial and increasingly leveraged resource for advancing human quality of life; however, its utility is constrained by inherent physical and spectral limitations. This thesis examines two distinct resource optimization problems critical to the sustainable development of space. The first part of this work addresses the optimization of physical orbital space. Unlike a terrestrial resource, mismanagement of this orbital space can lead to a runaway cascade of collisions, destroying the utility of entire orbital regimes. This thesis proposes a conjunction metric to quantify orbital capacity based on Keplerian parameters. We develop a computational tool to measure and …

Female-led NGOs and the feminist lens offer a revolutionary way to shape permanent peacekeeping efforts by emphasizing human rights and …

Interdependence In Practice: U.S. Travel Advisories And Turkey’S Economic Resilience, Matthew Michael Mccall

Honors Theses

This study examines the U.S. Travel Advisory and its economic impact on foreign nations, with a focus on Turkey between 2016 and 2024. Grounded in the theories of functional and asymmetrical interdependence, this approach employs a mixed-methods design, combining quantitative analysis of tourism revenue, GDP, and GNI with qualitative examination of geopolitical events that may raise or lower the Travel Advisory rating. Rather than assuming the advisory acts as a tool of coercive foreign policy, this study tests whether advisory changes meaningfully shape Turkey’s economic performance or whether they simply reflect moments of instability inside the country. The findings support …

Imagery Intelligence And Presidential Crisis Decision-Making: The Case Of The Cuban Missile Crisis, Codie Mcdonald

Honors Theses

Although the Cuban Missile Crisis was a short period of time relative to our nation’s history, this research has illuminated how much information, tension, and impactful moments lie within each minute; and the fact is, intelligence collection absolutely is a main factor in the de-escalation of the nuclear threat. Without the intelligence collection and production that was completed and given to Kennedy, policy would not be able to be made nearly as easy. Throughout each moment of the crisis, generally speaking, IMINT was able to provide and support the most aid to President Kennedy and his advisers. While the degree …

Challenging Batson: Interest Convergence And Permanence Of Racism In Jury Selection, Addrain Conyers, Amanda Bergold, Antoinette Critelli

The Scholar: St. Mary's Law Review on Race and Social Justice

A Batson challenge is an objection to the use of peremptory challenges to dismiss potential jurors based on their race; however, Batson challenges are rarely successful. In this paper, we apply Critical Race Theory (CRT) as a framework to analyze the Batson Challenge. More specifically, we argue that the Batson challenge is a practice grounded in interest convergence that underscores the permanence of racism in the judicial system. We explore three interests of Batson: (1) the protection of the Sixth Amendment right to a fair trial; (2) the protection of the Fourteenth Amendment; and (3) the promotion of public trust …

Polyminhash: Efficient Area-Based Minhashing Of Polygons For Approximate Nearest Neighbor Search, Alima Subedi, Sankalpa Pokharel, Satish Puri

Computer Science Faculty Research & Creative Works

Similarity searches are a critical task in data mining. As datasets grow larger, exact nearest neighbor searches quickly become unfeasible, leading to the adoption of approximate nearest neighbor (ANN) searches. ANN has been studied for text data, images, and trajectories. However, there has been little effort to develop ANN systems for polygons in spatial database systems and geographic information systems. We present PolyMinHash, a system for approximate polygon similarity search that adapts MinHashing into a novel 2D polygon-hashing scheme to generate short, similarity-preserving signatures of input polygons. Minhash is generated by counting the number of randomly sampled points needed before …

Tindak Pidana Korupsi Oleh Partai Politik: Urgensi Dan Implikasi Hukum Terhadap Pembubarannya Dalam Sistem Ketatanegaraan Indonesia, Ivani Ananda, Alya Alania Basmine, Nadhira Putri

Jurnal Konstitusi & Demokrasi

Corruption has become an extraordinary crime that damages the integrity of the state and weakens the democratic system, including through the role of political parties that are supposed to be the main pillars of democracy. This research aims to answer the main question: can a political party be dissolved because it is proven to have committed a corruption crime? Using a normative-juridical research method, this paper examines the provisions in the Anti-Corruption Law, the Political Party Law, and the Constitutional Court Law and is associated with the e-KTP corruption case study. The results show that normatively political parties can be …

From Fear To Familiar: Decreasing Technology Anxiety Among Older Adults In A Senior Community, Regina Rayz

Master's Projects and Capstones

Objective: Older adults (defined by the WHO as those 65 and older in developed countries) are more susceptible to technophobia than younger adults (Song et al., 2025). The fear and anxiety occurs with use of smartphones, tablets, social media, and telehealth and is associated with higher rates of social isolation and reduced autonomy. Technology-use anxiety is a preventative obstacle that inhibits both technology acceptance as well as overall health (Kim et al., 2023). Aim: To reduce technology-related anxiety among older low-income adults living in a senior residential facility in Richmond, CA by at least 25% using a brief, individualized technology …

Bicultural Identity, Work-Life Balance And Mental Health Outcomes In Swana Students, Julie M. Salama

Master's Theses

Southwest Asian and North African (SWANA) college students navigate academic demands alongside immigration-salient stressors that may shape their mental health and academic performance. This study examined generational status (Gen 1 vs. Gen 2+), identity conflict, ethnic identity, and work–life balance (WLB) in overall GPA and major GPA, and mental health outcomes of depression (PHQ-9), and anxiety (GAD-7) among SWANA students (N = 35). Two one-way MANOVAs found no generational differences for academics (overall/major GPA) or mental health (PHQ-9/GAD-7). Identity conflict was unrelated to GPA or symptoms but was positively associated with ethnic identity, while WLB was negatively correlated with depression …

A Trigger For The Autonomous Decommissioning Of Smart Devices, Ravindra Mangar, Jared Chandler, Jingyu Qian, Carl A. Gunter, Timothy J. Pierson, David Kotz

Dartmouth Scholarship

Smart devices are ubiquitous in modern environments, yet their decommissioning phase remains poorly studied and often overlooked in system design. We define secure decommissioning as the process by which a smart device securely disconnects from its environment and makes sensitive data inaccessible. If not decommissioned, devices may retain sensitive information – such as security credentials or user-behavior data that could be recovered by an adversary. Unfortunately, some users may forget to decommission a device when they dispose or sell it, and cannot decommission a device that is lost or stolen. This paper investigates a trigger mechanism for individual wireless smart …

Stewart, Donna Niedzwiecki, Melissa Lowe, Ashley Moyer, Emily Bolch, Shannon Diane Maclaughlan, Edward A. Levine, Omeed Moaven, Niharika Mettu, John H. Strickler, Dan G. Blazer

School of Medicine Faculty Publications

Peritoneal surface malignancies (PSMs) remain a therapeutic challenge, particularly in patients with unresectable disease who cannot benefit from cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. The Talimogene Laherparepvec for the Treatment of Peritoneal Surface Malignancies (TEMPO) trial (NCT03663712) is the first phase 1, multicenter, open-label study to evaluate intraperitoneal (i.p.) administration of talimogene laherparepvec (T-VEC), an FDA-approved oncolytic virus, in this setting. Nineteen patients with unresectable PSMs from appendiceal, ovarian, small bowel, and peritoneal carcinomas were enrolled; 18 received treatment across three escalating dose cohorts (4 × 10-4×10 PFU). The primary endpoint was safety and tolerability, with secondary endpoints assessing viral …

Application Of Augmented Reality Technology As A Dietary Monitoring And Control Measure Among Adults: A Systematic Review, Gabrielle Victoria Gonzalez, Bingjing Mao, Ruxin Wang, Wen Liu, Chen Wang, Tung Sung Tseng

School of Public Health Faculty Publications

Background/Objectives: Traditional dietary monitoring methods such as 24 h recalls rely on self-report, leading to recall bias and underreporting. Similarly, dietary control approaches, including portion control and calorie restriction, depend on user accuracy and consistency. Augmented reality (AR) offers a promising alternative for improving dietary monitoring and control by enhancing engagement, feedback accuracy, and user learning. This systematic review aimed to examine how AR technologies are implemented to support dietary monitoring and control and to evaluate their usability and effectiveness among adults. Methods: A systematic search of PubMed, CINAHL, and Embase identified studies published between 2000 and 2025 that evaluated …

The Policy Project: Translating Menstrual Equity Resources, Ashley Jackman

Undergraduate Honors Theses

This creative project focuses on translating key materials from The Period Project, a campaign by the Utah nonprofit The Policy Project that tackles menstrual inequity by pushing for free period products in schools and public spaces. Their educational toolkits guide students and parents toward menstrual resources and outline compliance requirements for school administrators. However, a significant portion of Utah’s population speaks Spanish at home, and current toolkits are not readily available in Spanish. As a Spanish translation major, I saw this as an opportunity to use my skills in a real-world setting, as the translated toolkit will be immediately electronically …

Reimagining Nurse Education: Virtual Reality & Didactic Education For Better Nurse Handoff And Documentation, Haley M. Whalen

Master's Projects and Capstones

Setting: The pediatric perianesthesia unit (pre-operative and post-anesthesia care unit). Problem: Gaps in perianesthesia documentation contribute to poor handoff communication, leading to adverse events and increased hospital costs. Additionally, inconsistent documentation reduces clarity and consistency during handoffs. Context: Staff in the microsystem reported low confidence scores with required OP-Time documentation, inconsistent workflows, and I-PASS handoff expectations. These factors contribute to incomplete charting and a lack of standardization across providers. Interventions: A two-part educational intervention was conducted, consisting of eight sessions. The first component is a Virtual Reality (VR) simulation that demonstrates an accurate perianesthesia I-PASS handoff. The second …

Promoting Interprofessional Collaboration By Increasing Visibility Of Volunteer Doula Services, Ciera Rose Zelie

Master's Projects and Capstones

Objective: The 22-bed Labor and Delivery (L&D) unit lacks a standardized model to introduce doulas, clarify their scope of practice, or communicate the value of the services they provide. To address this gap, the team developed a standardized doula awareness poster featuring each doula's name, photo, years of experience, and personal interests. Aim: Enhance visibility and promote the integration of doula support to strengthen team collaboration and patient engagement. Methods: A pre- and post-implementation survey was distributed exclusively to the volunteer doulas. After the doula awareness poster was displayed for four weeks, a post-survey assessed these same domains to determine …
