Functional Analysis In The Home Setting Of An Older Adult With Neurocognitive Disorder, Emily Norton

Masters Theses

Currently within the behavioral gerontology literature there are no published studies that include a functional assessment in the home setting. The primary goal of the present study was to address this gap by conducting a functional analysis on a challenging behavior of an older adult with neurocognitive disorder in the home. This study occurred in two phases. During phase one, researchers conducted an antecedent functional analysis on the bizarre speech of an 81-year-old female with suspected dementia across four conditions (television on, no interactions initiated; television on, interactions initiated; television off, no interactions initiated; television off, interactions initiated). Results from …

Potential Implications For Music Therapy On Nursing Assessment Of Patients With Dementia In Hospice, Kamilla Akmuradova

Masters Theses

Patients with Alzheimer’s disease (AD) display symptoms that cause disturbances in memory, learning, language, motor ability, and behavior. Hospice medical professionals frequently experience difficulty when performing any treatment physical in nature, such as conducting a physical assessment, changing a wound dressing and wound care, and administering medications, since patients with (AD) often exhibit symptoms of agitation, anxiety, and combative behaviors before and during procedures. In addition, complex communication and cognitive impairments cause challenges with assessment and intervention planning. Music as a complex auditory modality can enhance state of alertness, physical movement, facial expressions, physiological responses (e.g., heart rate), and communication …

Assessing The Impact Of 3d Printed Terrain On Teaching Topography In Introductory Earth Science Labs, Jay Alan Cockrell

Masters Theses

Learning to effectively read topographic maps is challenging for students, as these maps contain 3D representations of terrain displayed on a 2D surface map. This project assessed student learning when 3D terrain printed from a portion of the laboratory quadrangle map currently in use was introduced into an earth science course for non-science majors. Using a quasi-experimental design with nonequivalent groups across two semesters, performance on the Modified Topographic Map Assessment (MTMA) administered as a pre- and posttest was used to compare learning outcomes between the traditional lab and the 3D print lab intervention. Students in the traditional (n = …

Evaluating The Effects Of Sodium, Potassium, Magnesium, And Calcium Concentrations On Dolomite Stoichiometry, Cation Ordering, And Reaction Rate, Hanna F. Cohen

Masters Theses

Numerous environmental factors affect dolomitization. Shallow peritidal and restricted marine environments, for example, are often associated with more abundant and more stoichiometric dolomite than deeper marine environments. Higher fluid Mg/Ca ratios resulting from gypsum precipitation are often invoked to explain this observation, even when evidence of evaporites is absent. In this study, high-temperature dolomitization experiments show that the concentrations of major cation concentrations (Na, K, Mg, and Ca) impact dolomite stoichiometry and reaction rate. Nearly 200 batch dolomitization experiments were run whereby 100 mg of natural aragonite ooids were dolomitized at 215°C in ionic solutions. Fluid [NaCl] and [KCl] correlate …

Extending The Capabilities Of Von Neumann With A Dataflow Sub-Isa, Martin Cowley

Masters Theses

Instruction set architectures (ISAs) such as x86, ARM, and RISC-V follow the control flow model of computation, where a program is defined as a sequence of instructions. Early processors executed instructions one-by-one based on the control flow of a program. Dataflow is an alternative model of computation that uses the availability of data to drive instruction execution. Any instruction can be chosen for execution, independent of the instruction order, as long as the data is available for that instruction. While modern processors incorporate concepts of the dataflow model in the microarchitecture, the implementation of the ISA, the amount of instruction …

Estimation Of The Fatigue Life Of Additively Manufactured Metallic Components Using Modified Strain Life Parameters Based On Surface Roughness, Peter Grohs

Masters Theses

In this study, a method is developed to estimate the effects of surface roughness on the fatigue life of additively manufactured titanium Ti6Al4V, aluminum 7075–T6, and steel 4340 alloys through modified strain life parameters using finite element analysis (FEA). This method is highly beneficial to the fatigue analysis of as-built additively manufactured metal components, which possess rough surfaces that reduce fatigue life significantly but are challenging to analyze directly using finite element simulation because of complex geometries, i.e., modeling an exact surface profile is arduous.

An effective stress concentration factor, incorporating roughness data, is defined to quantify their effects on …

Intracellular Electrometer, Lucas M. Essenburg

Masters Theses

The Western Michigan University Neurobiology Engineering Laboratory conducts re- search in energy-efficient electrical stimulation of biological neurons. Experimental work re- quires an intracellular electrometer to inject nanoamp-level currents into a biological neuron and to measure its membrane voltage response. In order to fully understand the generation of such minute currents, an `in-house' electrometer was designed, constructed, and validated. This required exploration of various design trade-offs including precision of generated nanoamp-level currents vs. susceptibility to noise, portability vs. functionality, and cost vs. functionality. The electrometer was successfully used to stimulate and measure responses of neurons from the medicinal leech Hirudo verbana …

Masters Theses

The National Highway Traffic Safety Association (2018) reported approximately 6,000 pedestrians were fatally injured by vehicles in 2016, with an increasing trend in fatalities over the past decade. The gateway configuration of In-Street signs has been shown to produce an increase in the percentage of drivers yielding right-of-way to pedestrians; this study examined at what distance in advance of the gateway the configuration was most effective in inducing drivers to yield right of way further in advance of the crosswalk. This study also counterbalanced time of day across placement distances. Data were collected on all vehicles that passed through the …

Pcr Analysis On The Effects Of Alpha Synuclein Treatment On C6 Rat Glioma Cells, Michael John Helmus

Masters Theses

Multiple System Atrophy (MSA) is a rare neurological disease that mainly implicates the neuronal protein, alpha synuclein, as being centrally involved in MSA pathology. Despite synucleinopathy dogma, little is known about alpha synucleins role in MSA pathogenesis. The Ide laboratory previously conducted an Affymetrix gene expression study utilizing the post-mortem pons tissue from eight individuals with MSA and five individuals without any known neurological disorders. One conclusion from that study was that downregulation of numerous mitochondrial homeostasis related genes had occurred. It is hypothesized that alpha synuclein can perturb mitochondrial homeostasis through direct interaction with mitochondria. This study utilized Reverse …

Masters Theses

Accelerated and advanced development of the electronics industry in the 21st century is creating the rapid obsolescence of electrical and electronic equipment. This causes one of the largest and unstoppable waste streams called electronic waste (e-waste). There have been obstacles in e-waste recycling, including the existence of the informal sector such as peddlers (a larger issue in developing countries) and insufficient consumer awareness. The ideal e-waste recycling system would be able to overcome these obstacles. To establish an effective e-waste recycling system, the first important step is to implement an e-waste collection system. To implement an e-waste collection system, many …

Free Spirit Meets Gilded Cage: Betty Ford As Second Lady 1973-1974, Caroline Marie Dickey

Masters Theses

Betty Ford has a rich legacy as a pioneer and trailblazer, but her transition into politics was far from smooth. 1973-1974, or her time as Second Lady, was a critical training ground that solidified her beliefs and character for the rest of her life in the spotlight.

Gearbox Baffle Optimization, Megan Arduin

Masters Theses

Current literature reveals there is limited consensus on the placement of baffles within a gearbox to reduce churning losses. Thus, there is a need for a process to identify baffle clearances that result in maximum and minimum churning losses. There are two types of baffles: axial and radial. While both axial and radial baffles cause reductions in churning losses to various degrees, the focus is on the effect of radial baffles. The effect of a board (rectangular plate) baffle location on the churning losses of a single gear gearbox are evaluated using computational fluid dynamics (CFD) implemented in Ansys. Several …

A Comparison Of The Efficacy Of Gutter Pan And Curb Top Placement With A Full Gateway Configuration Of The In-Street Sign On Driver Yielding To Pedestrians, Erik Newton

Masters Theses

Driver yielding behavior at crosswalks directly affects pedestrian safety. In this study we examined whether the placement of the signs in the gutter pan or on top of the curb, while using a full gateway configuration of the in-street sign, influenced the efficacy of the treatment. Data were collected at sites using both in gutter and on top of curb full gateway configurations. The gutter pan configuration resulted in a higher percentage of driver yielding behavior to pedestrians in the crosswalk. The gateway treatment was shown to be more effective in the gutter pan configuration than the curb top configuration …

A Comparative Study On The Stability And Degradation Of Perovskite Solar Cells, Jyotiska Chakraborty

Masters Theses

This study aims to investigate the environmental factors that affect the performance and longterm stability of the perovskite solar cells (PSCs). PSCs are based on organo-metallic halides (perovskites) that act as a light-sensitive compound that produces excitons when placed under the light. However, PSCs have a limited operating lifetime due to the degradation of the perovskite layer. There are many factors like moisture, UV light, and temperature that lead to the degradation of the perovskite layer. From the literature review, it was found that the PSCs do not degrade with the presence of oxygen in a dry and dark environment. …

An Evaluation Of Unmanned Aerial Systems And Structure-From-Motion For Fluvial Large Wood Sensing And Risk Assessment, Daniel Gerke

Masters Theses

This research aims to show Unmanned Aerial System (UAS) and Structure-from-Motion (SfM) technology can, in combination, improve on traditional large wood (LW) monitoring techniques. More temporally and economically efficient data collected at a finer spatial resolution and greater spatial extent will increase the effectiveness of management plans and risk assessment for LW by providing decision-makers with a complete picture of the river.

Contemporary practices are too inefficient in time and labor for large-scale monitoring of fluvial LW with anything more than the most general management or risk assessment in mind. The paradigm of river research, the river continuum concept (RCC), …

Reconsidering ‘Soul And Body Ii’: Who Is Culpable For Their Combined Fate?, Sarah Jaran

Masters Theses

Soul and Body II has been considered for many years by scholars to be a less doctrinally complex poem compared to later versions of the topos. Superficially, the poem seems to blame the body fully for the shared doomed fate of the body and soul because the majority of the poem is a speech by the soul claiming that much. I propose in this study, however, that the poet created a dual message for the audience of Soul and Body II. While the easy and more superficial message is that the body is at fault for the damnation of …

There is limited research and literature on the effectiveness of narrative-centered academic learning environments that utilize biblical metanarrative as a tool for teaching. Literature exists showing that story is an effective tool within education, within discipleship, and within training for cross-cultural effectiveness. This narrative inquiry research study focused on Liberty University’s Global Studies Program, a program that overlaps these distinct areas into one platform. Global Studies uses the power of story through the Grand Narrative of Scripture to teach students academic content, equip them as messengers of God’s Story, and help them assess and understand their own narratives within a …

The Theological Implications Of Κατάπαυσίν And Σαββατισμὸς In Hebrews 3:7–4:11, Sean M. Best

Masters Theses

This thesis will argue that rest in Hebrews is entering into humanity’s rightful place, ruling over creation with God, in the full image of God, as intended by God since the seventh day. Rest in the book of Hebrews is a vitally important theme. The word for rest in Greek is κατάπαυσίν and is used eight times in Hebrews 3–4. The definition of rest determines the crux of understanding the warning passage by the author of Hebrews. The basic lexical definition of this word is “rest” or “resting place.” While a basic gloss of the Greek term κατάπαυσίν is easy …

The Design And Development Of A Device To Assist In Boosting Patients, Taylor A. Rieckhoff

Masters Theses

A common task a nurse is required to perform is called boosting patients. Boosting a patient is defined as lifting or sliding a patient back up in the bed after having slid down (Mannheim, Zieve, & Conaway, 2017). The current method for boosting patients involves a minimum of two personnel and an 11-step process. The 11-step process requires the person to manually lift and pull the patient using an existing half sheet on the bed (Mannheim, Zieve, & Conaway, 2017). Patients who cannot move or support themselves are moved every two to six hours or upon request (Bihn, Rieckhoff, Burkman, …

The Implementation Of Qpcr Beach Monitoring Methods: Analysis Of A Multi-Lab Validation Study And The Role Of Environmental Parameters On A Comparison Of Colilert And Qpcr Methods, Molly J. Lane

Masters Theses

Public beaches are routinely tested for potentially pathogenic bacteria to protect beachgoers from possible illness. An EPA approved method, Colilert™, used for testing E. coli in recreational water requires 18 – 22 hours before a result is reported but, recreators have already contacted unsafe water before the beach is closed. My study focused on a U.S. EPA proposed qPCR method (Draft Method C) to quantify E. coli in recreational waters that can provide same-day results. In Chapter 2, I examined the calibration procedure used to validate Draft Method C and compared standard curve intercept and slope estimates calculated with a …

Snowshoe Hare (Lepus Americanus) Abundance In Relation To Habitat And Predator Assemblage Across The Apostle Islands, Jarod Reibel

Masters Theses

Snowshoe hares (Lepus americanus) are a climate sensitive species that have a southern range boundary moving northward. Snowshoe hares are found on the Apostle Islands, Wisconsin which are near their southern boundary and differ by island in vegetative and carnivore communities. The archipelago serves as a natural laboratory to assess how top-down and bottomup forces interact and impact snowshoe hare populations. The objectives of this study were to determine the influence of vegetative characteristics, specifically visual obstruction, and the presence of predators on snowshoe hare abundances across the Apostle Islands. We conducted fecal pellet surveys to estimate hare abundance, measured …

Habitat Use Of The Climate-Sensitive Snowshoe Hare (Lepus Americanus) In The Manistee National Forest In Michigan’S Lower Peninsula, Spencer D. West

Masters Theses

Snowshoe hares (Lepus americanus) are a wide-ranging lagomorph that are important forest herbivores and a popular game species throughout their range. Across the southern boundary of their geographic range, snowshoe hares are experiencing population declines and possible extirpation due to increased predation pressure driven by climate change induced camouflage mismatch, competition for forage, degraded and fragmented habitat. One method of reversing the negative trends in snowshoe hare distribution is to increase and improve available hare habitat. A specific habitat analysis for local regions will most effectively advise managers how to target habitat management. I radio-collared 11 snowshoe hares in the …

A Cfd Study On The Performance Of High Speed Planing Hulls, Mowgli J. Crosby

Masters Theses

Most high speed water craft are able to achieve high speeds through the use of a planing hull. Planing hulls use hydrodynamic forces to lift a portion of the vessel out of the water, reducing drag, and allowing for greater speeds. Determining the flow around such vessels is traditionally achieved using a scale model in a tow tank. The purpose of this study was to analyze the performance of a high speed planing hull determine the effects of several geometric features using computational fluid dynamics rather than traditional experimentation. The goal was to determine the best configuration to ensure the …

Impacts Of Shoreline Restoration And Source Of Nutrient Enrichment On Macrophytes And Epiphytic Algal Communities, Paige Marie Kleindl

Masters Theses

Macrophytes and their epiphytic algal communities are integral for optimizing littoral ecosystem functioning in lakes. Epiphytic algae’s placement on the plant’s surface can reduce light and nutrient availability (i.e., nitrogen and phosphorus) for the host macrophyte. Macrophyte and epiphytic algal proximity complicates these primary producer group interactions and responses to bioavailable nutrients in the water column or porewater. For example, epiphytic algae may have a competitive advantage over surface water nutrients compared to macrophytes, which may have a competitive advantage over porewater nutrients via root systems.

Muskegon Lake’s industrial history and designation as an Area of Concern prompted shoreline restoration, …

Radio Direction Finding Using Pseudo-Doppler For Uav-Based Animal Tracking, Anup Karki

Masters Theses

Radio Direction Finding (RDF) is commonly used for low cost tracking and navigation systems. However, for a low cost application and mobility, the design constraints are highly limited. Pseudo Doppler (PD) can improve RDF capabilities without being cost prohibitive. This work entails the analysis of PD RDF and its potential use for Unmanned Aerial Vehicles (UAV) that are currently employed in wildlife research animal tracking. PD is based on the doppler effect or doppler shift. The doppler effect works like a frequency modulator that increases or decreases the observed frequency depending on whether a signal source is approaching or receding …

This study is focused on a rapid review of using music therapy towards social development in children with disabilities. Also explored is the researcher’s self-awareness of what was learned from the study and how these lessons may be transferred to future clinical work. The study's findings may also help music therapy professionals better understand (a) what aspects of social behavior music therapists tend …

Differentiating Epileptic From Psychogenic Nonepileptic Eeg Signals Using Time Frequency And Information Theoretic Measures Of Connectivity, Sarah Barnes

Masters Theses

Differentiating psychogenic nonepileptic seizures from epileptic seizures is a difficult task that requires timely recording of psychogenic events using video electroencephalography (EEG). Interpretation of video EEG to distinguish epileptic features from signal artifacts is error prone and can lead to misdiagnosis of psychogenic seizures as epileptic seizures resulting in undue stress and ineffective treatment with antiepileptic drugs. In this study, an automated surface EEG analysis was implemented to investigate differences between patients classified as having psychogenic or epileptic seizures. Surface EEG signals were grouped corresponding to the anatomical lobes of the brain (frontal, parietal, temporal, and occipital) and central coronal …

Genesis 10 & 11: A Theological And Geographical Framework For The Mission Of Paul, Jackson Scott Richardson

Masters Theses

The aim of this thesis is to offer a holistic solution to the purpose problem. Current scholarship has yet to provide a perspective that accounts for both the theological perspectives of Paul’s missional work and geographical plans of Paul’s missionary journeys. By establishing the Table of Nations and the Tower of Babel as a common factor from which Paul’s theological perspectives and geographical decision making derive, this study will build a foundation from which future work can gain insight into Pauline thought and encourage a renewed emphasis on understanding Genesis 10 and 11 when considering biblical study of the New …
