The Need For Standardized Training For Volunteer Healthcare Chaplains, Dominic Anthony Korzecki
The Need For Standardized Training For Volunteer Healthcare Chaplains, Dominic Anthony Korzecki
Masters Theses
For the past 50 years, many studies have examined the effects of Spiritual Care in medical environments. Though these studies have helped support the legitimacy and necessity for the presence of spiritual care in medicine, a lack of attention has been given to the level of professionalism of those who have been granted permission to administer care. The objective of my thesis is to determine the following: 1) if medical organizations that utilize volunteer-only spiritual care programs for their patients, and families, provide the same level of care as ones staffed by trained professionals, 2) if volunteer-only chaplaincy programs generate …
The City Clerk And The Body In The Basement, Celeste J. Mcfall
The City Clerk And The Body In The Basement, Celeste J. Mcfall
Masters Theses
Writing has been not only my source of income, but also an avenue to display my own thoughts through the words of others for the past four decades. Being able to incorporate my own personality across the genres in written form has given me, and many readers, an expanded knowledge and enjoyment. While it is well known that writing has physical and mental health benefits, quite often writers don’t realize how much of themselves is poured into their work. This theory was especially true for me during the COVID years, when I worked, mostly alone, as the City Clerk for …
Habitat Suitability For Age-0 Lake Sturgeon In The Grand River, Benjamin D. Gunnett
Habitat Suitability For Age-0 Lake Sturgeon In The Grand River, Benjamin D. Gunnett
Masters Theses
Lake sturgeon (Acipenser fulvescens) are a state-threatened species in Michigan and have become a focus for conservation. The lower Grand River is home to a remnant population of lake sturgeon between the 6th Street dam in downtown Grand Rapids and Lake Michigan. There has been limited research on age-0 lake sturgeon habitat use in low-gradient and more turbid rivers. To address this deficit, we developed a Habitat Suitability Index (HSI) for age-0 lake sturgeon based on prior literature in the Great Lakes. A HSI combines parameters representing in-stream habitat characteristics to score habitat suitability on a scale of 0-1, 0 …

Evaluation Of Dietary Probiotic Supplements On Methamphetamine-Induced Impulsive Action In Rats Maintained On A Differential Reinforcement Of Low Rate Schedule, Kaitlyn Steck
Masters Theses
Substance Use Disorder (SUD) is a chronic, debilitating condition often comorbid with anxiety and depression. Both SUD and affective disorders are characterized by cognitive dysfunction, including impaired decision-making and impulsivity. A mounting body of research implicates gut microbiome alterations as a contributing factor to the pathophysiology of affective disorders. No published studies have assessed behavioral effects of dietary interventions targeting psychostimulant-induced gut microbiome changes. The present study utilized a differential reinforcement of low rate responding schedule (DRL 18 s) as a behavioral index of drug-induced impulsive action to determine if a dietary probiotic supplement alters the behavioral effects of (+)-methamphetamine …

Hydrophobic Deep Eutectic Solvents: Liquid-Liquid Extraction Of Organic Water Pollutants, Abigail Louise Maletta
Masters Theses
Pollution is a topic of significant research within the scientific community. The massive demand for industrial processes to deliver the technology and resources we rely on has opened numerous avenues for pollutants to enter the environment, affecting air, water, soil, and the food chain. Oftentimes, these pathways are intertwined, and the interplay between water and air currents spreads pollution globally, creating a cascade of environmental impacts. Water, a vital resource for all forms of life, is particularly susceptible to industrial pollution. Among the most prevalent water pollutants are heavy metals, such as lead and mercury, and organic compounds, often released …
Spirit Marches West: An Application Of Hegel’S Historical Methodology To The American Frontier, Magnus Imber
Spirit Marches West: An Application Of Hegel’S Historical Methodology To The American Frontier, Magnus Imber
Masters Theses
The philosophy of history developed by Georg Wilhelm Friedrich Hegel incorporates the systematicity and speculative rationalizations that characterize his other major philosophical endeavors. Despite this, far less investigative work has been directed toward the contemporary applicability of Hegel’s philosophy of history than has been for his other major projects. Considering scholars’ much-diminished interest in speculative, overarching accounts of world history, this is not particularly surprising. Given, however, that the concept of rational historical progress is central to Hegel’s system, the contemporary applicability of the Hegelian conception of history seems to be a matter of significant importance. Can the methodology that …

Mass spectrometry is a technique that organizes material samples by mass to reveal their chemical composition by forming a spectrum. Since their invention, ion trap mass spectrometers have undergone significant enhancements. This work, funded by the National Science Foundation and in collaboration with Brigham Young University, the Simplified Coaxial Ion Trap (SCIT), attempts to simplify ion trap geometry and combine three ion traps into one device. Successful demonstration of the SCIT functionality could reduce costs, reduce manufacturing complexity, and shrink total instrument volume. At the same time, trapping capacity and analytical efficiency will be increased. However, as discussed within, challenges …
The Weight Of Gratitude And The Burden Of Truth, Joshua Macer
The Weight Of Gratitude And The Burden Of Truth, Joshua Macer
Masters Theses
The roots of this thesis lie in a daily journal written in a tattered notebook while deployed to the war-torn city of Baghdad, Iraq. The artist's statement tells the story of how the tragic events of 9/11 led to a decade of service in the military and how a simple daily journal kept during combat became the foundation for a memoir. Times passing, memory issues from injuries sustained overseas, and conflicting stories led the author to question the accuracy of military memoirs. The critical theory paper evaluates authenticity in memoirs, the challenges to truth and memories, and the consequences of …
Three Years With Buffalo Bill, Russell Storman
Three Years With Buffalo Bill, Russell Storman
Masters Theses
John Muir is the father of modern creative nonfiction in the outdoor adventure/nature genre. His passion inspired generations of Christian writers, especially within the genre, to draw connections between the God of their faith and His hand that they see in the natural world. Set in a forty-two-mile hike through northwest Wyoming’s Buffalo Bill State Park and continuing in the example set by Muir, the manuscript Three Years with Buffalo Bill establishes that faith is an essential element of modern life.
Shaping Character: The Role Of Mythology In Society, Jaclyn Weist
Shaping Character: The Role Of Mythology In Society, Jaclyn Weist
Masters Theses
Throughout history, man has told stories. Some stories were written on walls, tablets, or bits of parchment. Others have been passed down to posterity through oral tradition. Every culture worldwide has a rich tapestry of legends and myths. It is my intent to demonstrate that these stories use the tools of character development within their various plot lines to both express and shape beliefs, superstitions, and life lessons. Whether they are religious in nature or simply trying to make sense of the world, these stories, myths, and legends have played a part in shaping society into what it is today.
The Nature Of Beauty And Its Objective Manifestation Serve As Evidence Of The God Described In The Bible, Michael S. Libby
The Nature Of Beauty And Its Objective Manifestation Serve As Evidence Of The God Described In The Bible, Michael S. Libby
Masters Theses
In exploring the concept of objective beauty in nature, a strong argument emerges for the existence of a divine creator as described in the Bible. This thesis, titled “The Nature of Beauty and its Objective Manifestation Serve as Evidence of the God Described in the Bible,” proposes that the intricate design and objective manifestation of beauty in the world are indicative of a higher transcendent being, prompting us to contemplate the profound mysteries of creation and the interconnectedness of aesthetics and spirituality.

The Modern-Day Widow: Wrongly Shamed And Shunned In Evangelical Communities, Nancy Beise
The Modern-Day Widow: Wrongly Shamed And Shunned In Evangelical Communities, Nancy Beise
Masters Theses
Evangelical women suffering in destructive, abusive marriages suffer doubly when their faith communities do not understand the nature of intimate partner violence and the trauma of sexual betrayal. Too often these women are sent back into dangerous relationships without resource and with the additional burden of shame (Matthew 23:4). If they choose to divorce in order to escape abuse and find peace and healing, they are most often rejected and shunned as sinners. This work identifies who these women are according to scripture, defines abuse and betrayal trauma, and calls the evangelical community to an awareness of the suffering made …

Somali Students In The American Elementary General Music Classroom, Alice L. Charland
Somali Students In The American Elementary General Music Classroom, Alice L. Charland
Masters Theses
Education must be cognizant of the Somali culture’s inclination to classify music as a morally charged entity. It must also be careful not to forget American cultural values that have defined the music classroom. The purpose of this research was to identify Somali cultural expressions that occur in the American elementary general music classroom and to identify underlying concepts that contribute to these cultural expressions. Additionally, the research sought to bring light to the relationship between the two, so that future music educators might be inspired to create assessments and activities that better suit the needs of all learners.
Headstarting Eastern Box Turtles In Southwest Michigan: Implications For Growth, Survival, And Spatial Ecology, Faith C. Kuzma
Headstarting Eastern Box Turtles In Southwest Michigan: Implications For Growth, Survival, And Spatial Ecology, Faith C. Kuzma
Masters Theses
Turtles and tortoises are one of the most endangered groups of animals in the world as anthropogenic activities like overexploitation, collection for the pet trade, and habitat loss and fragmentation have caused dramatic population declines in recent years. As a result, proactive conservation techniques are being increasingly implemented to facilitate population recovery. Headstarting is a popular chelonian conservation technique that aims to reduce vulnerability and increase survival of juvenile turtles. While headstarting has been a valuable tool for many species, there is increasing evidence that species-specific influences impact its success. In this study, we headstarted four annual cohorts of eastern …
Differential Tail Autotomy Between Two Genetic Clades Of A Woodland Salamander, Plethodon Cinereus, Ryan Mayer
Differential Tail Autotomy Between Two Genetic Clades Of A Woodland Salamander, Plethodon Cinereus, Ryan Mayer
Masters Theses
Following the retreat of glaciers in North America, a wide diversity of organisms rapidly migrated into previously uninhabited regions, including animals with limited dispersal abilities such as amphibians. I wanted to better understand the strategies that salamanders use to aid in their dispersal abilities and to understand if patterns of post-glacial range expansion affect phenotypic traits such as anti-predator strategies. In this study, I used existing phylogeographic evidence of clade membership as a framework to examine whether red-backed salamanders (Plethodon cinereus) differed in tail autotomy behavior at the range edge versus the range core, and across the geographic range of …

A Comparative Study Of Biocrusts On Gypsum And Non-Gypsum Soils In The Northern Chihuahuan And Eastern Mojave Deserts, Usa: Biocrust Mosses Respond To Soil, Environmental, And Climatic Conditions, Katelyn Gobbie
Masters Theses
Biological soil crust communities (biocrusts) growing on gypsum soils have been well- documented for their prolific appearance and rich diversity of lichens and bryophytes. However, studies characterizing gypsum biocrusts have primarily occurred outside of the U.S., most of which lack comparisons to other soil types. We conducted intensive field surveys to evaluate the cover and frequency of biocrust functional groups and moss species on gypsum and non-gypsum soils in the U.S. regions with the most extensive gypsum outcrops, the northern Chihuahuan and eastern Mojave Deserts. We employed canonical correspondence analysis (CCA) to relate the observed differences in biocrust abundance and …
Do The Sexually Dimorphic Biofluorescent Glands Of Plethodon Cinereus Function In Mate Choice And Are They Seasonally Regulated By Photoperiod?, Sam C. Moody-Wynn
Do The Sexually Dimorphic Biofluorescent Glands Of Plethodon Cinereus Function In Mate Choice And Are They Seasonally Regulated By Photoperiod?, Sam C. Moody-Wynn
Masters Theses
The novel biofluorescent glands of the Eastern Red-backed Salamander (Plethodon cinereus), have been shown to be sexually dimorphic where males have larger and greater numbers of glands than females. Interestingly, a seasonal pattern of increased numbers of fluorescent glands, which mirrors the peak in testosterone levels, has been described. Currently, the function and regulation of the fluorescent glands is unknown. I predicted that the glands function as a form of male ornamentation used in intersexual communication, and perhaps act as an honest signal of male quality. Even though the fluorescent glands are located on the underside of the tail, there …
Upa-Mediated Polyamidoamine Dendrimer-Based Targeted Gene Delivery System On Triple-Negative Breast Cancer, Hsin-Yin Chuang
Upa-Mediated Polyamidoamine Dendrimer-Based Targeted Gene Delivery System On Triple-Negative Breast Cancer, Hsin-Yin Chuang
Masters Theses
"Around 15% of breast cancers are triple-negative breast cancer (TNBC), which is characterized by the absence of three common receptors—ER, PR, and HER2, and therefore do not respond to hormonal or anti-HER2 therapies. It is urgent to explore targeted therapeutic strategies for TNBC due to its poor prognosis and rare effective targeted therapy. In this study, we developed a polyamidoamine (PAMAM) dendrimer-based targeted gene delivery system—GDP-uPA, to utilize urokinase-type plasminogen activator (uPA) to target uPA receptor (uPAR), which is highly expressed in both TNBC cells and cancer-associated stromal cells. Our results of 1H NMR spectrum, TEM imaging, and MTT assay …

Hysplit In Simulating The Atmospheric Dispersion Of Hazardous Aerosols: A Case Study In St. Louis, Missouri, Ahmet Tolga Odabasi
Masters Theses
"Atmospheric dispersion and transmission play an important role in the behavior and effects of air pollution. Human health can be adversely affected by air pollution in a variety of ways, both immediately and over time. The Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT) modeling program, a computer model and software package, tracks the transport trajectories and distributions of air pollution and various pollutants, including radioactive pollutants, in the atmosphere. It also facilitates research on pollution sources. This study simulated the transport of hazardous aerosols in St. Louis region for the years 2020, 2021, and 2022 using the HYSPLIT modeling …
Branching Fractional Brownian Motion, Reece Beattie-Hauser
Branching Fractional Brownian Motion, Reece Beattie-Hauser
Masters Theses
"Fractional Brownian Motion (FBM) is a Gaussian process whose increments are correlated over long times. FBM is an example of anomalous diffusion, and recently it has been used to model the distribution of serotonergic fibers in the brain [1, 2]. To better represent these fibers, branching FBM (bFBM), where FBM trajectories may randomly split into two, is introduced. One-dimensional bFBM is studied in both sub diffusive and super diffusive regimes, examining three potential behaviors of the correlations (memory) in a branching event: both trajectories retain the memory of previous steps, only one keeps the memory, and neither keeps the memory. …

Metal-Ion Doped Borate Bioactive Glasses- A Novel Direction In Minimizing Nosocomial Infections And Antibiotic Resistance, Sarah Fakher
Masters Theses
"Nosocomial infections represent a formidable challenge and induce a substantial burden on patients and healthcare systems. These infections result from the interaction of numerous pathogenic microorganisms, particularly bacteria, and lead to increased morbidity, mortality, and healthcare costs. Extensive research has been carried out to devise innovative solutions, mainly focusing on antimicrobial natural and synthetic substances. However, the proclivity of bacterial strains to form biofilms complicates treatment and elevates antibiotic resistance, prompting research into pioneering more effective and versatile antibacterial strategies. Borate bioactive glasses (BBGs) are the latest, remarkable classes of biomaterials with a wide array of medical applications, owing to …
Protein Turnover Rate And Life History As An Explanation Of The Extreme Difference In Cost Of Biosynthesis In Cockroach Nymphs And Painted Lady Butterfly Larva, Kyara Nicole Holloway
Protein Turnover Rate And Life History As An Explanation Of The Extreme Difference In Cost Of Biosynthesis In Cockroach Nymphs And Painted Lady Butterfly Larva, Kyara Nicole Holloway
Masters Theses
The cost of biosynthesis in painted lady caterpillars is far lower than that of a red runner cockroach. A promising explanation for this phenomenon is the protein turnover rate for the animal during biosynthesis and tissue maintenance. Previous research has shown that, per gram of body weight, the painted lady butterfly can synthesize a biomass using up to 15x less energy and resources than the cockroach, even under similar conditions. The resulting ratios, especially in respect to growth rate, show a wide disparity between species in such a manner that does support a protein synthesis and degradation rates as a …
A Binary Integer Linear Programming Model For Optimizing Underground Stope Layout, Theophilus Mensah
A Binary Integer Linear Programming Model For Optimizing Underground Stope Layout, Theophilus Mensah
Masters Theses
"Underground mine planning engineers face significant challenges when determining what geometry provides the most profitable and safe stope for extraction. Several techniques and optimization algorithms have been developed in recent years, but most fail to find optimal solutions because they are heuristic or LP-based without efficient geometric constraints. This thesis work proposes a two-dimensional binary linear programming (BILP) model for determining the optimal combination of blocks in a stope that maximizes the economic value of the layout of stopes for a sublevel deposit. The work draws from Queyranne and Wolsey’s (2017 & 2018) formulations of tight constraints for bounded up/down …
