Molecular And Histologic Studies Of The Amygdala And Reward Circuits In Rhesus Macaques (Macaca Mulatta) With Self-Injurious Behavior (Sib), Jackie Barua

Doctoral Dissertations

Self-injurious behavior (SIB), also known as non-suicidal self-injury (NSSI), is characterized by deliberate infliction of harming one’s own body tissues without committing suicide, and persists in a group of captive rhesus macaques despite an enhanced enrichment program and pharmacological intervention with diazepam. The aim of this dissertation was to identify the neurobiological underpinnings of SIB by combining RNA-seq guided transcriptomic discovery and targeted candidate gene validation with unbiased histological and imaging analysis. The secondary aim was to employ a complementary mouse model to investigate the endogenous opioid system in response to diazepam. The amygdala transcriptome of primates with SIB (n …

Enhancing Hiv Prevention: Implementation And Evaluation Of A Standardized Hiv Risk Assessment Screening In A Primary Care Setting, William Duckworth

Doctoral Dissertations

Background: HIV remains a persistent public health concern, with 1.3 million people affected worldwide. Although advances in treatment have improved long-term management, early prevention still relies on identifying individuals at elevated risk. In many primary care settings, routine HIV risk assessment is inconsistent or absent, resulting in missed opportunities to screen, educate and initiate prevention strategies such as pre-exposure prophylaxis (PrEP). This gap underscores the need for structured, evidence-based tools to improve early risk identification and strengthen HIV prevention efforts. Purpose: Implement and evaluate an evidence-based standardized screening process for HIV risk assessment to achieve early identification and enhance appropriate …

Enhancing Hpv Vaccination Engagement And Uptake Among Young Adults Aged 17 To 26 Through A Multilevel, Multicomponent Intervention, Sarah Dianne Girlinghouse

Doctoral Dissertations

Background: Human papillomavirus (HPV) remains one of the most common vaccine-preventable infections, with vaccination rates among young adults aged 17 to 26 remaining below Healthy People 2030 targets.

6tisch Based Sensing Network For Smart Agriculture, Riley Heike, Griffin Jones, Justin Odo, Jalen Paige, Rosalie Wessels

Computer Science and Engineering Senior Theses

This project investigates 6TiSCH (IPv6 over Time-Slotted Channel Hopping), a relatively recent IETF networking standard introduced in 2013 that combines deterministic TSCH scheduling, 6LoWPAN header compression, and RPL mesh routing to enable low-power, reliable, multi-hop wireless communication for IoT deployments. Despite its strong theoretical properties, 6TiSCH remains underexplored in practice, and real-world questions around configuration, scalability, power behavior, and end-to-end integration are not well documented. Our primary goal was to build and operate a working 6TiSCH network, characterize its performance through iterative testing, and understand what it takes to go from raw packet delivery to a complete data pipeline.

A Simulation-Based Lean Six Sigma Framework For Process Optimization In Textile Manufacturing Toward Industry 4.0, Md Shafiqul Islam Chowdhury

Masters Theses

This study focuses on integrating simulation modeling with Lean Six Sigma (LSS) within the DMAIC (Define, Measure, Analyze, Improve, Control) framework for process optimization in textile manufacturing industry. Although traditional LSS framework such as Value Stream Mapping (VSM) and Root Cause Analysis are effective in identifying waste, they mainly rely on static and historical data which make their capability limited for real analysis or predictive decision making. As a result, many textile manufacturing processes still face challenges such as production delays, excessive work-in-process (WIP), high cycle time, and inefficient resource utilization. To address this issue, this research proposes a simulation-based …

Severity Of Deficit In Skeletal Muscle Lipid Metabolism Invokes Unique Adaptive Responses In Dietary Lipid Intake And Absorption, Victoria Datta

Masters Theses

Skeletal muscle plays a central role in whole-body lipid metabolism through mitochondrial and peroxisomal fatty acid oxidation (FAO). When skeletal muscle lipid metabolism is impaired, whole-body adaptations occur to maintain metabolic homeostasis. We hypothesized that limiting skeletal muscle lipid metabolism through mitochondria and/or peroxisomes would trigger adaptive responses to reduce dietary lipid intake and/or absorption with the most robust changes coinciding with deficit severity. Mice were generated with skeletal muscle-specific deletion of 1) carnitine palmitoyltransferase 1b (Cpt1bM-/-) to limit mitochondrial FAO, 2) peroxin 5 (Pex5M-/-) to impair peroxisomal FAO, and 3) both Cpt1b and Pex5 (DKO). Results were compared to …

Beyond Social Disconnection: The Unique Relationship Between Existential Loneliness And Depression, Lauren Beatrice Edwards

Masters Theses

Depression and loneliness are among the most pressing mental health concerns in the United States, yet their relationship remains incompletely understood. Research has extensively examined social-emotional, or general, loneliness. However, existential loneliness (EL), the felt sense of being fundamentally alone in one's existence, has remained on the theoretical periphery. This study examined EL as a meaningfully distinct dimension of loneliness and explored its unique relationship with depressive symptoms in a sample of 301 U.S. adults recruited via Prolific. A joint exploratory factor analysis confirmed that EL and general loneliness are empirically separable dimensions of loneliness. Regression analyses revealed that EL …

Micro-Hyperspectral Imaging Of Phytoplankton Enables Deconvolution Of Mixed Communities For Spaceborne Hyperspectral Remote Sensing, Chisom Okwuchi Emeghiebo

Masters Theses

Characterizing phytoplankton diversity is critical for large-scale biodiversity monitoring and harmful algal bloom (HAB) detection. Here, we present a micro hyperspectral imaging method to characterize reflectance signatures, for the first time across major phytoplankton groups. Spectral variability among taxa in laboratory cultures is interpreted using algal pigment and absorption analyses, demonstrating that pigment composition and absorption govern reflectance features. Chlorophytes and cryptophytes exhibit distinct spectral signatures and are readily distinguishable, whereas diatoms and dinoflagellates show greater spectral similarity, with differentiation relying on subtle reflectance features associated with chlorophyll c₁c₂ near ~463 nm and within 620–650 nm. We further applied this …

The Effect Of Perceived Support On Black College Students' Sense Of Belonging, Jamillia Domani Mckinley

Masters Theses

Black college students oftentimes navigate higher education environments while managing academic demands alongside racialized stressor that can weaken their sense of belonging. Existing literature and research examined peer relationships, faculty support, and institutional support separately; however, little to no studies considered how these forms of support operate together in shaping belonging. The current study addressed that gap by examining whether perceived peer support, teacher support, and institutional support predict Black students’ sense of belonging in college and university settings. Through the lens of Maslow’s Hierarchy of Needs, belonging was viewed as a foundational need for confidence, connection, growth, and self …

Linking Greenhouse Gas Fluxes And Plant Responses To Saltwater Intrusion Events Using Remote Sensing, Madeline Jean Moore

Masters Theses

As sea level rise and coastal subsidence increase coastal Louisiana's vulnerability to saltwater intrusion (SWI) events, accurate and rapid monitoring of vegetation responses to these events is becoming increasingly important. In this study, we utilized unmanned aerial vehicle (UAV) multispectral imagery to assess short-term vegetation responses to simulated SWI events in the Visser’s Experimental Wetland Complex in Saint Martinville, Louisiana. Vegetation patches of two common freshwater wetland species, Panicum hemitomon (Maidencane) and Typha domingensis (Southern Cattail), were exposed to 5 ppt salinity for 6-, 10-, and 17-day durations. Multispectral imagery of both species was collected before and after each SWI …

Guided by Wen and Miura’s (2023) motivation-based Model of Online Disinhibition, this study examined how individual factors and motives for using Tinder predict online disinhibition and subsequent disinhibited behaviors. Specifically, using an English translation of Wen & Miura’s Multi-dimensional Measure of Online Disinhibition (2024), the study tested whether gender and five Tinder use motives—sexual experience, entertainment, romance, socializing, and distraction—predicted levels of online disinhibition on Tinder and whether online disinhibition, in turn, predicted …

The Relationship Between Self-Stigma, Psychological Inflexibility, And Help-Seeking Attitudes Across Three Different Groups: A Cross-Cultural Study, Mst Tajlima Tamanna

Masters Theses

Self-stigma of mental illness is one of the most important factors that influence people’s help-seeking attitudes. A higher level of self-stigma is associated with less favorable attitudes toward help-seeking. Additionally, psychological inflexibility may also contribute to this process by increasing people’s tendency to internalize the negative stereotypes associated with mental illness, which contributes to higher self-stigma. The present study examined the relationships between self-stigma of mental illness, psychological inflexibility, and help-seeking attitudes across three groups: Bangladeshi students living in Bangladesh (Group 1), Bangladeshi students living in the United States (Group 2), and United States college students (Group 3). A total …

Disparities In The Identification Of Vulnerable Communities Due To Design Storm Methods: A Case Study In The Vermilion River Watershed, South Louisiana, Usa, Claire Orgeron

Masters Theses

Accurately identifying socially vulnerable populations at-risk of flooding is critical for equitable disaster mitigation and planning. This study investigates how the selection of design storm method, which is fundamental to developing flood risk maps used for this identification, influences which socially vulnerable populations are recognized as being at elevated flood risk. The most widely used design storm approach relies on National Oceanic and Atmospheric Administration (NOAA) Atlas 14 point-based rainfall frequency estimates. These estimates are typically applied spatially using areal reduction factors, thereby disregarding rainfall spatial variability in real storms. Stochastic Storm Transposition (SST), an alternative design storm approach that …

Forests, Lakes, And "Hidden" Housing, Kenneth M. Johnson, Mark J. Ducey, Barbara D. Cook, Kathryn L. Cottingham

Carsey Publications

Human settlement patterns have significant implications for the natural environment, including freshwater lakes. People are attracted to areas with abundant lakes. However, dense human settlement near lakes can have adverse impacts on lakes by reducing forest cover, increasing nutrient loads, decreasing aquatic vegetation, and introducing invasive species. In addition, dense human settlement near lakes increases the health risks associated with cyanobacteria (also known as “blue-green algae”) blooms.

In this brief, a multi-disciplinary team of researchers focuses on the interaction between human development and forest land near lakes across ten selected U.S. counties and on the limitations of remote satellite imagery …
