Characterization Of Glyt1 Expression And Glycinergic Circuits, Laura Patricia Montes

Open Access Theses & Dissertations

Glycine is one of the main inhibitory neurotransmitters in the central nervous system. Glycine is regulated by the glycine transporters 1 and 2 (GlyT1 and GlyT2, respectively) in the synaptic cleft. Both transporters participate in glycinergic inhibitory neurotransmission. Moreover, GlyT1 also participates in glutamatergic excitatory neurotransmission. GlyT2 is devoted to caudal regions of the brain and is used as a marker for glycinergic neurons. In contrast, GlyT1 is expressed across the brain in the rostrocaudal axis and is highly associated with GlyT1-positive glial cells. Data from our laboratory has identified GlyT1-positive neurons in the rodent brain. Therefore, we hypothesize that …

Temporal Partitioning And Coexistence Among Four Sympatric Felid Species In The Northern Jaguar Reserve, Kylie Marie Rezendes

Open Access Theses & Dissertations

Coexistence among sympatric carnivores is shaped by behavioral strategies that mediate competition and mortality risk in heterogeneous landscapes. Understanding how sympatric carnivores, such as felids, use space and time in relation to one another requires models that account for both spatial and temporal overlap across landscapes. Models incorporating time-to-event probabilities provide a powerful framework for detecting behavioral dynamics across shared landscapes. This study evaluated the spatiotemporal responses of two apex predators â?? the jaguar (Panthera onca) and mountain lion (Puma concolor) - and two mesopredators - bobcat (Lynx rufus) and ocelot (Leopardus pardalis) - across five years of camera trap …

Academic Experiences Of Historically Underrepresented Stem Students In Nontraditional Pathways, Karime H. Smith

Technology-Enabled Foreign Object (Fo) Prevention, Christopher Lee Colaw

Open Access Theses & Dissertations

The aviation industry incurs $14 billion per year in cost due to Foreign Object (FO) damage and the prevention and resolution techniques associated with foreign object debris. While aircraft loss, material scrap and rework contribute to that cost impact, a traditional approach to aircraft design and manufacturing which is based on human performance is also a significant driver. Failure modes and effects analysis of human based aircraft manufacturing reveals that two of the largest risks are associated with unknown potential for FO creation and the inability to recall or objectively provide evidence of FO conformity for cases of inquiry, learning, …

Line Outage Impact Factors: A New Approach To Line Outage Detection With Machine Learning, Daniel Flores

Open Access Theses & Dissertations

Electric power systems have become one of our most critical infrastructures as we've grown dependent on electricity for everyday tasks. Ensuring power systems provide reliable service is a priority that can be affected by disturbance events. A common event is transmission line outages, where a line in the system becomes disconnected due to varying forms of physical damage. If an outage isn't detected in time, other lines in the system may overload, causing cascading failures that leave many customers without power. Therefore, having a power system that can automatically detect outages is crucial for reliability, as it promotes real-time response …

Environmental Drivers Of Vegetation Dynamics In Constructed And Natural Wetlands Of The Chihuahuan Desert, Enrique David Garcia

Open Access Theses & Dissertations

Desert wetlands are critical ecosystems that provide water, food, and habitat for many different species at different trophic levels. Additionally, they have the capacity to recharge aquifers, control floods, and purify water, among others. Unfortunately, they have been facing multiple environmental challenges due to different human activities, sometimes with disastrous consequences. There is an urgent need to better understand the structure and function of wetlands of different types and in different biomes in order to conserve, restore, and even create them so we can continue to obtain all the ecological services they provide. In this dissertation, I investigated how environmental …

Guest Editorial: Who’S Special Now?, Michael Maihofer Dds

The Journal of the Michigan Dental Association

This editorial discusses a controversial change in Michigan's dental specialty advertising law, which occurred in 2020. Previously, only state-recognized specialists, undergoing rigorous advanced training, could advertise their specialty status. However, a new rule, resulting from an out-of-court settlement, paradoxically allows general dentists not recognized as specialists to advertise as such without following advertising rules. This change is criticized for undermining public protection and creating unethical, misleading situations where general dentists advertise as pediatric dentists, for instance. The Michigan Dental Association (MDA) is actively working to revert this law by supporting House Bills 4593 and 4594 to ensure only recognized specialists …

Diagenesis And Controls On Porosity And Permeability In The Upper San Andres Formation Of West Texas, Jack Butcher

Electronic Theses and Dissertations

West Texas reservoirs on the Central Basin Platform (CBP) are dominated by Permian-age carbonate deposits, significantly contributing to petroleum production. The Upper Permian-aged San Andres Formation, composed primarily of dolomite and limestone, is a prolific reservoir. This study assesses diagenetic influences on porosity and permeability within the San Andres Formation along the northern CBP. Two cores from the Monument 4-2 and Peterson 1 wells in West Texas were analyzed using core descriptions, thin section petrography, XRD, XRF, and MICP. Results indicate that dolomitization enhances porosity, with intercrystalline and moldic porosity being dominant, while late-stage cementation and compaction reduce permeability. XRD …

Idiomatic Compositional Techniques In John Rutter's Requiem, Marguerite Walsh

Electronic Theses and Dissertations

John Rutter is an extremely significant figure in choral music, and his 1985 Requiem is one of his most widely performed works. Despite this popularity, it has yet to be analyzed in a rigorous academic capacity. Requiem is a harmonically rich and sophisticated work, and said lack of previous analysis represents a gap in theoretical research. This thesis analyzes Requiem for significant harmonic structures and idiomatic compositional techniques and applies those techniques in an original composition. Subtopics of note included harmonic non-functionality, modulations, and orchestration. The original work is comprised of two movements for choir and piano respectively titled “Requiem …

Evaluation Of A Forest Restoration Strategy On Small Mammals In Southern Pine Ecosystems, Gage R. Grantham, Jessica L. Glasscock, Christopher M. Schalk, Kathryn R. Kiid, Reuber Antoniazzi

Electronic Theses and Dissertations

Industrial forestry replanted historic native pine forests (e.g., longleaf pine [Pinus palustris] and shortleaf pine [Pinus echinata]) to homogenous, high-density plantations consisting of native off-site species (e.g., loblolly pine [Pinus taeda]) after intensive harvesting for wood products. The contemporary forest structure that remains, consisting of off-site overstory compositions, can potentially serve as an ecological bridge to facilitate a gradual transition to a more desirable canopy species, thereby conserving biodiversity and ecosystem function. Understanding disturbance-sensitive small mammal communities from restoration strategies (retention) can help achieve long-term management goals for ecosystem conservation across larger scales. I …

Using Silvopasture To Mitigate Heat Stress In Grazing Beef Cattle, Sydney L. Lofland

Electronic Theses and Dissertations

This study evaluated the impact of silvopasture on mitigating heat stress in grazing beef cattle by comparing physiological and behavioral responses between shaded and non-shaded pastures. Twenty-two multiparous cows were monitored over a 20-day summer trial in East Texas. Data were collected on respiration rate, heart rate, heat stress scores, and behaviors including eating, ruminating, walking, and resting. Average respiration rates and behavior proportions did not differ significantly between treatments. Afternoon periods showed peak physiological stress across all cattle, but silvopasture appeared to buffer extreme responses. Although limitations such as data gaps and a shortened trial impacted interpretation, findings suggest …

Stand Strucuture Of Planted Stands In Storm-Water Retention Basins, Jason Lanza

Electronic Theses and Dissertations

Trees assist in stormwater retention basin functionality as efficient sources of water removal, and determining stand structure and leaf area of forests can be a measure of their effectiveness. The structure of forest stands on these basins managed for runoff mitigation has received little attention. We investigated the structure and species composition/diversity (tree and herbaceous) of planted, managed stands and naturally regenerated stands on stormwater retention basins managed by Harris County Flood Control District in Harris County, Texas. We determined stand structure variables (trees per hectare, basal area per hectare, quadratic mean diameter, relative density, average tree height, and percent …

Between Compliance And Commitment: Community College Administrators And The Politics Of Dei Policy Implementation, Carol Birth

Graduate Theses and Dissertations

This qualitative case study explores how community college administrators navigate the complex and politically charged landscape of diversity, equity, and inclusion (DEI) policy implementation in the face of evolving state legislation. Grounded in Michael Lipsky’s theory of Street-Level Bureaucracy, the research examines how mid- to senior-level administrators perceive their interpretations, mediations, and actions on DEI mandates in contexts where such policies are contested or pressured. Using semi-structured interviews with administrators across multiple community colleges, the study investigates the tension between institutional commitment to DEI values and the necessity to comply with external political and legal directives. The study contributes to …

Coastal Consumption: Diet And Social Organization At Four Postclassic Sites In The Yucatán Peninsula, Paramita Choudhury

Graduate Theses and Dissertations

This research examines Postclassic Maya food practices during CE 1200–1600 to understand how eating behaviors reflect systems of social hierarchy, political economy, and cultural identity. The investigation focuses on four archaeological sites in the northern Yucatán Peninsula—Tulum, El Rey, El Meco, and San Miguelito—to examine dietary behaviors through dental microwear texture analysis (DMTA), oral pathology, and stable isotope data within a biocultural framework. The research aims to identify whether elite and non-elite individuals exhibited notable variations in food texture consumption, access to resources, and nutritional health. High-resolution 3D surface metrology enabled DMTA to assess the mechanical properties of consumed foods, …

Automated Chick Sexing Using Computer Vision, Marta Veganzones Rodriguez

Graduate Theses and Dissertations

This thesis presents two complementary approaches to chick sexing, a critical task in poultry production that demands accurate and early gender identification. By investigating both facial and vent-based modalities, we present two complementary methods that aim to improve the efficiency, scalability, and ethical standards of gender classification in day-old chicks through the use of computer vision and deep learning. The first approach draws inspiration from human facial gender recognition to introduce facial chick sexing, a minimally invasive technique that eliminates the need for expert knowledge. This system encompasses a complete pipeline that includes image acquisition, facial detection and alignment, keypoint …

Bilingual Program Implementation And Programming In The Midwestern And Southeastern United States: Lessons Learned For Application In Arkansas, Susan Wallace

Graduate Theses and Dissertations

As of 2025, the state of Arkansas has no state-approved bilingual or dual-language education programs, despite passing legislation in 2021 to allow for their creation. This literature review synthesizes findings from recent empirical studies conducted in the Midwestern and Southeastern United States—regions with demographic and policy contexts more similar to Arkansas than states with long-time bilingual programs. This literature review explores both beneficial and complicating factors in bilingual program implementation, addressing themes such as policy, leadership, stakeholder involvement, program design, and prevailing ideological mindsets, before summarizing lessons learned from these studies. The implications are clear: effective bilingual programming requires intentional, …

A Pastoral River: Reimagining The Narrative Of Buffalo National River, Thomas Andrew Medford

Graduate Theses and Dissertations

This thesis examines the creation of Buffalo National River (BNR) from the perspective of dispossessed landowners. A unit of the National Park Service in the Arkansas Ozarks, BNR has garnered little scholarly attention in this light, despite present-day resentment of the federal government by locals. The park was signed into law in 1972, capping a years-long debate about the fate of the river. Some had supported a tenacious U.S. Army Corps of Engineers effort to dam the river, others backed a well-organized, preservationist-led campaign to create a park, while on-the-river landowners typically preferred the status quo of private ownership. Many …
