Diagnostic Accuracy Of The Stopbang Questionnaire Against Polysomnography For The Screening Of Obstructive Sleep Apnea In A Tertiary Hospital In Kenya., Sandra Obaje Maseno

Master of Medicine in Internal Medicine

BACKGROUND: Obstructive sleep apnea is a syndrome of upper airway and neuromuscular dysfunction during sleep that subsequently causes interruption of normal breathing. Polysomnography is the reference test for the diagnosis of obstructive sleep apnea. Obstructive sleep apnea can be categorised as mild, moderate or severe based on an apnea-hypopnea index (AHI) on polysomnography. The recommended treatment using Continuous Positive Airway Pressure lowers morbidity and mortality rates. The STOPBANG questionnaire has been used as a screening tool for obstructive sleep apnea due to its easy and concise approach. However, even with the increasing prevalence of obstructive sleep apnea and its risk …

Autonomous, Yet Anchored: Exploring The Interplay Of Self-Reliance And Personal Spirituality On Employee Outcomes, Alexander Schad

All Dissertations

The modern workplace increasingly requires employees to function autonomously while managing limited psychological resources, presenting a tension between the benefits of self-reliance and its potential costs to well-being. This dissertation examined how self-reliance simultaneously influences task persistence and emotional exhaustion, and explores whether personal spirituality moderates these relationships. Drawing on the Strength Model of Self-Control (SMSC), I develop and test a theoretical framework investigating the relationships between self-reliance, work overload, task persistence, emotional exhaustion, and workplace spirituality.

Through a time-lagged field study with 453 working professionals across three measurement waves, I found that self-reliance positively predicted task persistence, supporting the …

Drawing On The Past: Understanding Japanese American Internment Through Camp Newspaper Comics, Rory Olsen

All Graduate Reports and Creative Projects, Fall 2023 to Present

When studying the past, what artifacts are left behind for us to study? In understanding Japanese American internment in the United States during WWII, camp newspapers help give a look at the reality of camp life, which included the ongoing issues of a lack of supplies,, the generational divide between older and younger Japanese Americans, and even the racist leanings of some members of the camp. With a balance of humor and seriousness, as well as reality and the abstract, three artists - Roy Kawamoto, Harry Kuwada, and Michiko "Rosie" Arima - who were interred in Camp Jerome (located near …

Development Of A High-Performance, Cost-Effective Architecture For Real-Time Fourier Transform Analysis On An Efinix Trion Fpga, Luke Cashwell

Honors Theses

This project presents the development of a high-performance, cost-effective, and powerefficient pipelined architecture designed to execute 10,000 Fast Fourier Transforms (FFTs) per second on an Efinix Trion T120 FPGA. Each FFT processes 4096 signed 13-bit elements, facilitating real-time data analysis for a Time-Domain Impedance Probe (TDIP) operating at a maximum data rate of 490 Mbit/s. The algorithm utilizes the built-in multipliers and dual-port memory cells of the FPGA to optimize data storage, transfer, and processing. It achieves this high performance while only using approximately 4% of the Look-Up Tables (LUTs), 7% of the integrated RAM cells, and 15% of the …

Funded To Win? Super Pacs And Electoral Advantage In The Southeast, Kyle Winstead

Honors Theses

2010 saw the introduction of a new player on the field of electoral finance, the super PAC. This introduction came with much controversy due to the widespread fear that super PACs could undermine the election system by giving wealthy individuals or organizations an undue influence. The literature on super PACs influence on the electoral system is inconclusive, with different studies having mixed results, meaning more information needs to be gathered. In this paper, I attempt to learn more about super PACs influence, particularly on congressional elections, by examining the results of congressional elections across three states: Alabama, Georgia, and Florida. …

Reducing Suicide Ideation Through Healthcare Provider Training In The Use Of The Columbia Suicide Severity Rating Scale (C-Ssrs) In A Rural Community Mental Health Clinic, Lashunda R. Lewis

Doctoral Projects

This doctoral project aimed to address the inconsistent and inadequate assessment of suicide risk by healthcare professionals in a Rural Community Clinic. Staff members do not comprehensively understand the Columbia-Suicide Severity Rating Scale and vary in how they screen patients before the intervention. When we looked at the baseline, we found that only 45% of charts contained suicide risk screening, and C-SSRS was used in only 5% of cases. Some of the main obstacles reported were not properly training staff and keeping patients from sharing their thoughts on this subject.

The main objective of the doctoral project was to test …

Parenting For Wellness: Positive Parenting Factors As Predictors Of College Student Physical Health, Mental Health, And Social Connectedness Through The Lens Of Self-Determination Theory, Mary E. Lamkin

Dissertations

Research suggests that the transition to college can impact college student well-being across the domains of physical health, mental health, and social connectedness (Frech, 2012; Pittman & Richmond, 2008; Xiao et al., 2017). As parents are more heavily connected to their college-aged students when compared to years before cell phones and social media, they likely continue to play a significant role in their child’s well-being, even while they are in college (Wartman & Savage, 2008). Therefore, the aim of this dissertation was to investigate positive parenting behaviors as predictors of wellness in college-aged participants using Self Determination Theory (Ryan & …

Coyote (Canis Latrans) And Non-Target Wildlife Responses To Livestock Guardian Dogs At Sheep Grazing Sites On The California Central Coast, Tricia T. Nguyen

Master's Theses

Livestock depredation is one of the oldest and most widespread forms of human-wildlife conflict. The coyote (Canis latrans), a midsized canid, represents a significant proportion of domestic sheep depredations in the United States, costing livestock producers an estimated 24.6 million dollars annually. Management strategies for coyote-sheep depredation vary widely in their effectiveness and in their level of public support. Identifying appropriate strategies for farms, ranches, and other sheep grazing sites remains a pressing need due to the potentially negative consequences for surrounding ecosystems and socioeconomic outcomes for sheep producers. The livestock guardian dog (LGD) is a nonlethal control …

Mazur’S Intersection Property And Its Variants, Deepak Gothwal

Doctoral Theses

We discuss various differentiability notions in connection with ball separation prop- erties. We characterise the uniform Mazur’s intersection property (UMIP) in terms of w*-semidenting points in attempt to resolve a long standing open question: “Does UMIP imply uniformly smooth renorming?” Further, we discuss a stronger version of UMIP called the hyperplane uniform Mazur intersection property (HUMIP) which is shown to characterise uniform smoothness. Similar ball separation char- acterisations are obtained for Fr´echet smoothness and asymptotic uniform smoothness (AUS). These ball separation properties are then shown to be residual properties. Thus, we obtain that norms which have UMIP or norms which …

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 …

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 …

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 …
