Microbial Guardians Of The Savannah: Unraveling The Gut Microbiome For African Carnivore Conservation, Laura E. Peirson

All NMU Master's Theses

Non-invasive fecal sampling is essential for wildlife gut microbiome (GMB) research, yet field conditions often limit preservation options. I compared gut bacterial communities in paired fecal samples preserved in stabilization tubes and air-dried in paper bags collected from anesthetized African lions (Panthera leo) and spotted hyenas (Crocuta crocuta) in Etosha National Park, Namibia. Additional opportunistic samples from carnivore kill sites were also analyzed. No significant differences in alpha or beta diversity were detected between preserved and dried samples, although bacterial beta diversity differed between preserved and opportunistic samples (PERMANOVA). Core bacterial communities remained consistent across sample …

Simulating The Blood Transfusion System In Kenya: Modelling Methods And Exploratory Analyses, Yiqi Tian, Bo Zeng, Jana Macleod, Gatwiri Murithi, Cindy Makanga, Hillary Barmasai, Linda Barnes, Rahul Bidanda, Tecla Chelagat, Carolyne Njoki

Anaesthesiology, East Africa

The process of collecting blood from donors and making it available for transfusion requires a complex series of operations involving multiple actors and different resources at each step. Ensuring hospitals receive adequate and safe blood for transfusion is a common challenge across low- and middle-income countries, but is rarely addressed from a system level. This paper presents the first use of discrete event simulation to study the blood system in Kenya and to explore the effect of variations and perturbations at different steps of the system on meeting blood demand at patient level. A process map of the Kenyan blood …

Data-Driven Stochastic Programming For Disaster Housing Logistics Planning, Sheng-Yin Chen

All Dissertations

This dissertation develops an integrated modeling and solution framework for direct temporary disaster housing logistics under demand uncertainty. The proposed framework addresses the problem from short-term, long-term, and computational perspectives. First, a two-stage chance-constrained stochastic programming (TSCC) model is developed for short-term housing logistic planning, with demand scenarios generated via a data-driven spatial regression model that captures the relationship between housing demand, hazard exposure, and socioeconomic factors. A case study based on Hurricane Ian demonstrates that the TSCC model outperforms deterministic and traditional scenario-based models in both solution quality and robustness. Second, to address long-term housing logistics planning, a multi-horizon …

Crevice Corrosion Mechanisms Of Cocrmo Alloys In Orthopedic Implants: Retrieval Analysis, Nano-Tribocorrosion And Cellular Responses, Hwaran Lee

All Dissertations

Mechanically assisted corrosion and non-mechanically (chemically) driven corrosion in modular junctions of orthopedic implants using cobalt-chromium-molybdenum (CoCrMo) alloys remain clinical concerns and may contribute to implant failure. The underlying corrosion mechanisms are not yet fully understood, leaving a critical research gap. We hypothesized that corrosion in modular junctions may be driven by aggressive local environments, including fretting, metal ion release (cobalt ion, Co²⁺), low pH and reactive oxygen species (ROS). This dissertation aims to (1) analyze corrosion modes and potential causes in modular junctions; (2) identify chemically driven corrosion modes on CoCrMo alloys using simulated inflammatory modular taper …

Three Essays On Mental Health Courts, Taylor E. Le Moal

All Dissertations

Mental illness in the criminal justice system is a major issue, with 2 in 5 incarcerated people in the US having a serious mental illness (Criminalization of People with Mental Illness, n.d.). Prisons have turned into “de facto” mental health facilities when these facilities are not equipped to do so. This means once individuals are released from incarceration, they are often ill-equipped to return to regular life and may get caught up in the cycle of recidivism (Slate, 2017). One method that policymakers have used to solve this problem is mental health courts (MHCs), which are pre-trial diversion …

Self-Poled P(Vdf-Trfe) Based Composites For Energy Harvesting And Wearable Sensor Applications, Lavanya Muthusamy

All Dissertations

The growing demand for flexible, low-power, and self-powered wearable electronic systems has accelerated research interest in polymer-based sensors and energy harvesting technologies. Among piezoelectric polymer materials, Poly(vinylidene fluoride-trifluoro ethylene) [P(VDF-TrFE)], over the years, has garnered significant attention due to its unique piezoelectric properties, high dielectric constant, mechanical flexibility, thermal stability, chemical resistance, biocompatibility and compatibility with scalable fabrication processes. Despite its advantages, conventional P(VDF-TrFE)-based devices often require external poling and face limitations in integration with low-cost, flexible substrates. To overcome these limitations, this research study explores the nanofiller approach, along with facile fabrication processes, and structural design strategies aimed at …

Understanding The Experiences Of White Female Elementary School Teachers Who Promote Racial Equity And Justice In White Schools, Meredith Valentine

Theses, Dissertations and Culminating Projects

In this qualitative study, I conducted semi-structured interviews of six white, female elementary school teachers to better understand how and why they enacted principles of racial equity to challenge the status quo of whiteness with their predominantly white middle-class students and school community. Teachers felt they lacked a formal, structured education to feel confident in their teaching of racial and social justice concepts. Teachers used other forms of social justice teaching that they were more experientially familiar with, such as gender equity, language diversity, and (dis)ability, as a catalyst to discuss topics of racial justice. Each educator navigated their classroom …

Advanced Specificity And Sensitivity Studies Relative To A Research Use Only Transcription-Mediated Amplification-Based Assay For Treponema Pallidum Rna Detection, Trinity Krueger, Grace Kadonsky, Elizabeth Thelen, Amanda Zapp, Josephine Moore, Ahmet Muslu, Allan Pillay, Irene A. Stafford, Erik Munson

Clinical Lab Sciences Faculty Research and Publications

Preliminary experimentation has suggested that a research-use-only real-time transcription-mediated amplification assay for Treponema pallidum (RUO T. pallidum TMA) yields instances of T. pallidum nucleic acid detection that coincide with non-treponemal serology in men who have sex with men (MSM) at increased risk for sexually transmitted infection. To further characterize the specificity of RUO T. pallidum TMA testing, 3,586 rectal swab specimens reported as “not detected” by the assay generated a mean endpoint FAM fluorescence of 637.5 units. Introduction of Treponema denticola, Treponema phagedenis, and Treponema refringens nucleic acid into matrices generated mean endpoint FAM fluorescence ranging from 620.7 …

Examining Employers’ Perspectives Relating To Early College High School Programs And Employability Skills, Kathleen Mcguigan

Education Doctoral

This phenomenological qualitative research study examined employer perspectives on the employability skills of graduates from Early College High School (ECHS) programs. The study investigated the program components that enhance the preparation of employability skills and the systems that support graduate transition to the workforce. Using semi-structured interviews with employer partners and an iterative coding process, three key themes emerged across the data. The key themes highlight the importance of factors relating to workplace readiness, including internships and experiential learning, behavioral and soft skills, and structured transition systems, as critical components in preparing ECHS graduates for employment.

The findings indicate that …

Improving Coastal Hydrodynamic Model Performance Through Parameter Sensitivity Analysis And Optimization, Sunni Siqueira Allen

LSU New Orleans Theses and Dissertations

This thesis presents a framework for parameter sensitivity analysis and optimization of coastal hydrodynamic models. The research uses the Generalized Likelihood Uncertainty Estimation (GLUE) method to quantify parameter sensitivity and identify optimal values for currents, wave height, and water level. A variance-based technique guides parameter selection when GLUE yields competing values or when observations are unavailable.

The framework is demonstrated through two case studies: Hurricane Michael (2018) and the ExCaliBur field study (2022) near Oceanside, CA. Results from Hurricane Michael show higher optimal hydrodynamic model bottom friction values near the hurricane's landfall location. The Oceanside study identifies the hydrodynamic model's …

Weber, Mengjun Shu, Ganesh Panzade, Connor J. Cooper, Russell B. Davidson, Jin-Gui Chen, Sara S. Jawdy, Jerry M. Parks, Breeanna R. Urbanowicz, Gerald A. Tuskan, Trupti Joshi, Richard A. Dixon, Wellington Muchero, Jaime Barros

Biomedical Sciences

The chemical composition of wood plays a pivotal role in the adaptability and structural integrity of trees. However, few studies have investigated the environmental factors that determine lignin composition and its biological significance in plants. Here, we examined the lignin syringyl-to-guaiacyl (S/G) ratio in members of a Populus trichocarpa population sourced from their native habitat and conducted a genome wide association study to identify genes linked to lignin formation. Our results revealed many significant associations, suggesting that lignin biosynthesis is a complex polygenic trait. Additionally, we found an increase in the S/G ratio from northern to southern geographic origin of …

Analysis Of The Scleroderma / Systemic Sclerosis Etiopathology Using The University Of California At Davis (Ucd)-Ssc Chicken Line, Angeline E. Rodriguez

Graduate Theses and Dissertations

Scleroderma/Systemic Sclerosis (SSc) is a multifaceted autoimmune disorder affecting approximately 300,000 people in the United States. Main features include vasculitis, immune dysfunction (innate and adaptive), autoantibody production, perivascular leukocyte infiltration, and extensive tissue fibrosis. The University of California, Davis (UCD) SSc chicken line was shown to exhibit all clinical and biological manifestations of human SSc. One early and distinctive clinical sign in both humans and UCD-SSc chickens is Raynaud’s phenomenon (RP), characterized by decreased blood flow in extremities and skin lesions. RP-like lesions develop in combs of UCD-SSc chickens within one- to two-weeks post-hatch, progressing from erythema and edema to …

Framing The Problem To Meet The Policy Solution: An Embedded Mixed Methods Case Study Of The 2017 Michigan Opioid Laws, Leandra Hawkins Burke

Dissertations

The opioid crisis presents a wicked problem for public administration. Hundreds of thousands of people have died from opioid overdoses in the United States, and countless others have experienced severe opioid-related physical, psychological, and socioeconomic harms. Countering the opioid crisis has been difficult due to interdependencies across different drugs and multiple pathways for abuse and dependence. Many scholars, health providers, and politicians have called for a broad public health approach to combat the opioid crisis, but the full expanse of what that would entail has not yet been realized. What has been demonstrated is that interactions targeting a single aspect …

The Impact Of Feedback Timing On Work Performance When There Is A Long Duration Between Sessions, Priyanka B. Dave

Dissertations

Performance feedback is a powerful tool central to many functions at work, as it guides, motivates, and rewards employees’ behaviors. To better understand the function of feedback, previous research has examined the impact of feedback’s timing (proximal to the previous per-formance versus proximal to the next performance) on the effectiveness of feedback. However, the findings have been mixed across studies. Studies with less than 1-day between session dura-tions tend to find no difference between after-session versus before-session feedback. However, investigations with multiple-day between session durations tend to find improved performance with before-session feedback. This study used a counterbalanced across-subject design …

Examination Of The Association Between Parent Beliefs About Injury And Supervision Behavior, Felicia Acelia Diaz

Dissertations

Unintentional Injuries are the leading cause of death for children in the United States (Centers for Disease Control and Prevention, National Center for Injury Prevention and Control, 2021). Several studies have indicated that caregiver beliefs (such as locus of control) are associated with children’s injury risk (Damashek et al., 2005), but few studies have examined whether caregiver beliefs about injury are related to caregiver’s injury prevention behaviors, such as caregiver supervision. Examination of caregiver beliefs regarding supervision revealed that caregiver’s degree of belief in the preventability of childhood injuries predicted self-report scores on several measures of supervision. Caregiver’s degree of …

Multiple Monochromatic Subgraphs In Edge-Colored Graphs, Emma Felicity Jent

Dissertations

Ramsey theory, though a relatively young branch of mathematics, has captivated the attention of graph theorists, combinatorialists, and theoretical computer scientists alike through its raw beauty, versatility, and powerful applications. Before it emerged as a branch of mathematics, the central idea of Ramsey theory appeared in the form of three lemmas in three separate papers by three different mathematicians working on three distinct areas of research. The first such lemma was published by David Hilbert in 1892, followed by the second lemma published by Issai Schur in 1916. However, Frank Ramsey’s renowned lemma, published in 1930, compelled mathematicians to establish …

"It Can Be Hard To Stand Up Straight In A Crooked Room:" Examining The Mediating Effects Of Black Women's Gendered Racial Identity On The Relationship Between The Strong Black Woman/Superwoman Schema And Collective Coping, Devin Willis

Dissertations

Prior research on the Strong Black Woman (SBW)/Superwoman (SW) schema has produced mixed findings. Both positive and negative outcomes of Black women’s internalization of this schema have been identified. These mixed findings may be linked to the measurement of the SBW/SW schema and the relationship with other culturally relevant variables. There have been significant positive relationships identified between Black women’s gendered racial identity (GRID) and the internalization of gendered racial stereotypes (i.e., the SBW/SW). Methods for coping with stereotypes have also been identified as influential when considering Black women’s coping behaviors.

The purpose of this study is to examine the …

Mechanistic And Evolutionary Insights Into A Group Of Nicotine And Hydroxynicotine Degrading Flavoenzymes, Zhiyao Zhang

Dissertations

Flavoprotein amine oxidases (FAOs) are key enzymes in various kinds of metabolic pathways, mediating redox reactions via flavin cofactors. While most FAOs function as oxidases that readily reduce oxygen to hydrogen peroxide, a few outliers of the FAO family act as dehydrogenases that suppress the reaction with oxygen. The molecular basis for this divergence in function remains poorly understood.

The work presented in this study investigates the fundamental mechanisms of how flavincontaining enzymes activate or suppress their reaction with different electron acceptors to achieve high turnover rates. The overall body of work is divided into three different sections that (1) …
