Development Of Novel Hydrogel Materials For Viscoelastically Accurate Brain Phantoms, Lila G. Schandler

Theses and Dissertations

Current methods such as concussion tests and Magnetic Resonance Imaging (MRI) scans only reveal structural damage post-injury. Creating an anatomically accurate model of the brain that mimics brain structure and viscoelastic properties will further allow medical professionals to analyze concussion events and create curated and personalized plans of recovery for a patient’s unique brain injury.

Values have been established for the necessary viscoelastic properties (time constants and elasticity) to mimic the native human brain tissue such as grey matter and white matter. The mechanical properties of the hydrogel are tunable by varying the concentration of Phytagel (PHY), a protein binding …

Applying X-Ray Fluorescence With Monte Carlo Methods For Analysis Of Surface Defects On Coated Zr4, James Tyler Cahill

Theses and Dissertations

Chromium-coated Zircaloy-4 cladding represents a novel solution for creating nuclear cladding that has passive safety features. This and related developments aimed at improving nuclear safety are broadly categorized as accident-tolerant fuel and cladding. However, implementing this material presents practical challenges such as the vulnerability that cladding has to surface damage such as fretting wear. This research aims to determine if the pre-existing technique of X-ray fluorescence analysis is applicable for detecting these defects on the surface of the cladding. This was done by developing Monte Carlo N-Particle Transport models of a handheld device, the XL-5, alongside experimental measurements using this …

Observed Parent And Child Differences In Black Mothers Of Children With And Without Attention-Deficit/Hyperactivity Disorder, Sydney E. Padgett

Theses and Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) is childhood's most common neuro- developmental disorder, mainly distinguished by a pattern of inattention, hyperactivity and/or impulsivity. Compared to the plethora of research on White children with ADHD, the research on Black children with ADHD is limited. Looking more closely at the functions related to parenting children with ADHD, there is even less information known on the interactions between Black children and their parents compared to White children and their parents. The primary aim of the thesis study was to compare observed parenting and child behaviors between Black mother/child dyads of children with and without ADHD. This …

Revising The Indian Plenary Power Doctrine, M. Henry Ishitani, Alexandra Fay

Michigan Journal of Race and Law

The federal Indian law doctrine of Congressional plenary power is long overdue for an overhaul. Since its troubling nineteenth-century origins in Kagama v. United States (1886), plenary power has justified invasive Congressional interventions and undermined Tribal sovereignty. The doctrine's legal basis remains a constitutional conundrum. This Article considers the Court's recent engagement with plenary power in Haaland v. Brackeen (2023). It argues that the Brackeen opinions may signal judicial readiness to reevaluate the doctrine. The Article takes ahold of Justice Gorsuch's critical assessment and runs with it, ultimately proposing a method for cleaning up this destructive and constitutionally dubious line …

Teaching Positive Psychology Lessons In An Intensive English Program, Carolee Rogers, Benjamin L. Mcmurry, Dan Dewey

Faculty Publications

This article investigates the effectiveness of positive psychology interventions (PPIs) in an intensive English program for non-matriculated university students. Interventions based on the PERMA model were implemented through weekly 65-minute lessons given during the first class of each week. These were followed by short daily activities during the rest of the week. Using positive psychology topics as the content, students concurrently engaged in language learning activities. Each participant was asked to complete a questionnaire at the end of the semester consisting of five open-ended questions relating to the PPIs, the lessons, the activities, the topics, and how they felt the …

Here-, There-, And Every Where-: Exploring The Role Of Pronominal Adverbs In Legal Language, David Chandler, Brett James Hashimoto

Faculty Publications

Many have claimed that pronominal adverbs, such as hereby, thereafter, and wherein, are a frequent, distinctive, and problematic in their use in legal language (Tiersma, 1999; Mellinkoff, 2004). The purpose of this study is to examine those claims empirically. In the present study, the prevalence of PAs in legal registers is compared to more general registers of contemporary American English to determine the extent to which these words are distinctly legal. The study will also explore why different types of PAs may be (in)frequent in specific legal registers to better understand their use. The frequency of PAs was extracted from …

Parent Motivations For Enrolling Their Young Children In Early Childhood Programs: An Application Of The Theory Of Planned Behaviour, Rachel A. Mcgovern, Camilla Hodge, Edward Ruddell

Faculty Publications

This study used the theory of planned behaviour to identify and determine the relative influence of factors influencing parents’ decisions to enrol their young children (3 to 5 years old) in early childhood programs at a specific museum venue. An eliciting questionnaire was distributed to museum members with at least one child 3–5 years old to elicit outcome expectancies, normative beliefs, and control beliefs, and these responses were developed into items for the main questionnaire. Regression and correlation analyses were conducted to determine factors associated with parents’ intention to enrol their children. Parents across socioeconomic and educational backgrounds indicated they …

Lest We Be Lemmings, Claire Wright

Faculty Articles

Lest We Be Lemmings concerns global warming, which is the most grave threat facing humanity today. In this article, I first: (1) discuss how the U.S. Congress and the U.S. Executive Branch, for decades, have been aware of the existence of global warming and its main cause – the burning of fossil fuels and emission of CO₂ - but have consistently failed to regulate the fossil fuel industry, reduce the lucrative subsidies that they provide to the fossil fuel industry, and hold the fossil fuel industry responsible for global warming; (2) explain how the fossil fuel industry, for decades, …

Municipal Abortion Bans: When Local Control Clashes With State Power, Laura D. Hermer

American University Journal of Gender, Social Policy & the Law

Anti-abortion activists are using different strategies in different states. Some focus on restricting zoning for abortion clinics. Others address the licensure of abortion providers. Some purport to create a cause of action for private individuals to sue neighbors and others in their municipality who get an abortion. Still, others seek to enforce the federal Comstock Act, alleging that it prohibits the mailing of abortifacients and preempts state abortion law to the contrary.

This Article evaluates the likely success of each of these strategies in two states in which they are currently being tried: Nebraska and New Mexico. Part I will …

Validation And Improvement Of Forest Health Risk Maps: A Case Study With Maple Decline/Dieback, Joseph R. Beeson

Dissertations, Master's Theses and Master's Reports

Forest health data collected in a two-phased survey of maple dieback was used to build on previous work, extending analysis into mapping implications. Using the National Insect and Disease Risk Maps (NIDRM) published by the US Forest Service as a baseline, we compared our collected data from 2009-2012 and 2021-2022 with the published 240m resolution sugar maple decline risk map, finding the NIDRM map to be a poor predictor of sugar maple dieback measured at the plots. Measured sugar maple crown dieback was also compared to measured soil characteristics and nutrient levels, and augmented with soil survey maps and long-term …

Hydrologic Pathways Of A Northern Hardwood Catchment In The Great Lakes Basin Using End Member Mixing Analysis, Cory C. Burkwald

Dissertations, Master's Theses and Master's Reports

This study investigated the seasonality of hydrologic pathways, the role of wetlands in streamflow generation, and how hydrologic pathways affect the export of nutrients by streamflow in the Sturgeon River using endmember mixing analysis. The results indicated that streamflow consists of three main components: shallow subsurface water from wetland soils, shallow groundwater, and surface runoff from precipitation. Snowmelt plays a dominating role in regulating stream water chemistry (~80% volume at peak) during the snowmelt season and likely also after that. Wetland soils store snowmelt, together with rainwater though the fraction is unknown, and then gradually release through summer in the …

Assessment Of Surface Waviness In A Wire Arc Additive Manufacturing Process, Shammas Mahmood Shafi

Dissertations, Master's Theses and Master's Reports

Wire Arc Additive Manufacturing (WAAM) is increasingly recognized for its ability to produce metal components with high deposition rates and efficiency, particularly in the aerospace and automotive sectors. However, one significant challenge that WAAM faces is achieving surface quality that complies with industry standards, as well as creating geometries that closely resemble the initial design. A crucial factor contributing to this challenge is surface waviness, which is an inherent characteristic of the WAAM process. This waviness arises from the geometry of the weld beads and the overlap distance between them. It can adversely affect the fusion quality of successive layers, …

Interplay Of Discharge Rates, Slope, And Sediment Size In River Meandering Dynamics: Insights From Experimental Studies, Yifan Zhang

Dissertations, Master's Theses and Master's Reports

Sinuosity is an important concept in various fields including hydrology, geomorphology, and ecology. It not only presents the degree of curviness of a river channel but also reflects the ecological sustaining ability. By studying the sinuosity of a stream or river channel, important implications could also be found including the transportation and deposition of the sediments, the habitats of the riverbanks, and the types of species that are able to live on the watershed and river. To study the factors that could heavily affect the sinuosity of a river channel, a full set of laboratory experiments was designed to perform …

Nickel Superalloy Composition And Process Optimization For Weldability, Cost, And Strength, Sophie A. Mehl

Dissertations, Master's Theses and Master's Reports

To advance sustainability efforts, electric power plants have reduced specific carbon dioxide emissions by increasing operating temperatures and pressures to improve power generation efficiency. The latest improvements are utilized in advanced ultra-supercritical power generation. To meet these operating conditions, nickel superalloys are used in the highest temperature components; however, they are expensive and present weldability challenges. This project aims to experimentally optimize a nickel superalloy to improve material weldability and decrease cost without compromising strength. Three optimized compositions were developed, and their microstructures and mechanical properties were compared to Nimonic 263, a common nickel superalloy in electric power plants. The …

The Implications Of Waste Streams At Camp Au Train, Timothy J. Maze

Dissertations, Master's Theses and Master's Reports

Archaeological remains from Camp Au Train provide an opportunity to understand sanitation methods during its use as a Civilian Conservation Corps camp and later used to house German Prisoners of War during World War II. Seven refuse features from this camp were excavated and their contents linked to functional locations within the camp in order to reconstruct waste streams across the site and to observe how military aspects of sanitation were implemented by an organization infamous for its emphasis on cleanliness, order, and hygiene. While the importance of sanitation is often mentioned by historians and archaeologists in research of these …

“Not Much Of A Job”: Everyday Life And Labor At Camp Au Train, Josef T. Iwanicki

Dissertations, Master's Theses and Master's Reports

In this thesis, I use data from Camp Au Train, a Civilian Conservation Corp camp in Michigan’s Hiawatha National Forest, as a case study to connect the everyday life of enrollees with dominant government narratives while including a focus on labor and the capitalist crisis of the Great Depression. Using the vantage point of work, play, study, and health, I integrate archaeological, historic, and photographic evidence to show contradictions between the enrollees’ real lived experience and the dominant perspectives of the CCC ‘authorities’ who organized their lives. I argue that to interpret these contradictions, the CCC needs to be connected …
