Health, Exercise, and Sports Sciences ETDs

The purpose of this study was to determine whether there is a difference in hemodynamic responses to head-up tilt (HUT) in subjects who do, and do not, experience acute mountain sickness (AMS) during exposure to hypobaric hypoxia. Secondarily, we aimed to determine if those hemodynamic variables altered during HUT correlated with AMS severity. Fifteen participants completed three testing sessions: 1) VO₂max test to determine workload at 50% VO₂max for hypoxia exposure; 2) HUT test consisting of supine rest for 20 min followed by 70° upright tilting for ≤ 40 min; and 3) six hours of hypobaric …

Characterization Of Partial Charge Collection Induced By Neutron Damage In High-Purity Germanium Detectors, James W. Evans

Nuclear Engineering ETDs

This paper investigates the correlation of damage induced by neutron interactions and degradation in the spectra of HPGe detectors. As neutrons kinetically interact with germanium crystals, they create interstitial and vacancy defects within the lattice. These defects then interfere with the charge migration of electron-hole pairs and reduce resolution in the observed energy spectrum. The partial charge collection produces observable spectral changes by increasing the peak width and reducing resolution (full width half maximum). A detailed characterization using various check sources was performed before and after iterations of neutron exposure in order to observe the effects of the neutron damage. …

My secondary questions were 1) how do mindfulness activities affect flow experiences among collegiate double bass music students, and 2) how do mindfulness activities affect students’ perception of self-care? The interviews were transcribed, coded using “concept coding” (Miler, Huberman, & Saldaña, 2020), and then grouped into categories, themes, and sub-themes. The themes were time, …

The Magic Of Love: Love Magic In Medieval Romance, Dalicia Raymond

English Language and Literature ETDs

This project examines authorial representations of the morality of three functions of love magic: to induce, to disrupt, and to facilitate love in twelfth- through fifteenth-century Middle High German, Old French, and Middle English romances. Using a cultural studies approach with close textual analysis and informed by gender studies, it investigates medieval romance authors’ discomfort with love inducing magic and asserts that this discomfort is a response to the magic’s violation of free will, a central tenet of medieval theology. I find that authors condemn love inducing magic but mark specific instances acceptable through explicit clarification of divine approval. Love …

Addiction, Attrition, And Visualizations: An Exploration Of Online Survey Panels, Alex Adams

Political Science ETDs

Due to changes in technology and individual behavior, survey methods for obtaining nationally representative public opinion survey data have changed dramatically. Survey methodologists increasingly rely on online survey panels. The data obtained from these panels is increasingly accepted as reliable for cross-sectional research designs, in part because these online survey panel samples are demographically representative on observable variables. However, over time the experience of panelists approximates a panel survey design.

This dissertation explores two concerns related to online survey panel data, (1) panel conditioning and the advent of a professional class of survey takers I call professional respondents, and (2) …

The Impact Of Social Interactions On Resettled Refugee Health, Shahjadi Zaman

Political Science ETDs

The purpose of this thesis is to investigate the effects of social interactions and other factors on the self-reported physical and mental health of former refugees in their host country. Social relationships and interactions consist of different layers extending from individual personal relations, to social networks, to collective activities. Using data from a public opinion survey of newly resettled Bhutanese and Rohingya refugees in Michigan, I find that along with their economic situations, like employment and income, social integration is an important determinant of physical and mental health among resettled refugees. In particular, resettled refugees tend to have better health …

An Autoethnography Of A Registered Nurse Living With Chronic Undiagnosed Illness, Frances M. Ricker

Nursing ETDs

Abstract

This autoethnographic study examines a registered nurse’s experience living with chronic undiagnosed illness. The number living with undiagnosed illness is unknown and little is understood about living with chronic undiagnosed illness.

This analytic autoethnography (Anderson, 2006) used multiple data sources: my journal, medical history narrative, and artifacts including my handwork, examples of my father’s handwriting, and family photographs. Narrative analysis, thematic analysis, and visual analysis were conducted.

My experience of living with chronic undiagnosed illness was characterized by three themes that reinforced isolation: not knowing, loss, and hidden secret self. Family context evidenced diverse themes of not being believed, …

Identifying, Understanding And Combating Complex Inequality: The Fight To Make The Invisible, Visible, Rachel Whitt

Black History at UNM

Dr. Nancy López, professor of sociology at UNM and director of the Institute for the Study of “Race” and Social Justice, explains the role of complex inequality in fueling social unrest. Complex inequality is rooted in decades of disparities towards minorities, particularly Blacks, Latinx, people of color and Native American communities. López outlines how invisible, deeply embedded injustices are common practice in the United States citing research that shows there are compounding challenges facing marginalized communities. These hurdles are multifaceted and cannot be distilled down to single data points. Recognizing the experience of marginality is layered and must be viewed …

Clinicopathologic Implications Of Myb And Beta-Catenin Expression In Adenoid Cystic Carcinoma, Susan Park, Manali Vora, Annemieke Van Zante, Joseph Humtsoe, Hyun-Su Kim, Sue Yom, Shweta Agarwal, Patrick Ha

Pathology Research and Scholarship

BACKGROUND: Adenoid cystic carcinoma (ACC) is the second most common malignancy of the salivary glands, accounting for ~ 1% of malignant tumors of the head and neck region and 10% of salivary gland neoplasms. Predicting the long-term outcomes of patients with ACC is still challenging, as reliable prognostic biomarkers are not available. Among salivary gland tumors, Myb overexpression is highly specific for ACC. In addition, the MYB-NF1B fusion translocation is a hallmark of ACC, and although the detection of this translocation does not appear to impact prognosis, the MYB-NF1B fusion is also implicated in MYB upregulation. Myb has recently been …

An Improved Method For Spectroscopic Quality Classification, Elizabeth G. Mayer

Mathematics & Statistics ETDs

Spectral quality classification is a vital step in data cleaning before the

analysis of magnetic resonance spectroscopy (MRS) data can be done. This

analysis compares five methods of quality classification; three of these are

legacy methods, Maudsley et al. (2006), Zhang et al. (2018), and

Bustillo et al. (2020), and two newly created methods that used a random forests

classifier (RFC) to inform their classifications. We found that the random forest

classifier was the most accurate at predicting spectra quality (balanced

accuracy for RF of 88% vs legacy of 70%, 72%, or 72%). A

Random-Forests-Informed Filtering method (RFIFM) for quality …

Combining High-Frequency Sensor Data And Nutrient Addition Experiments To Identify Uptake Dynamics In Streams, Justin Rae Nichols

Civil Engineering ETDs

Nutrient enrichment has led to impaired waterways across the globe with an estimated 90% of waterways in the U.S. being negatively impacted from anthropogenic sources. In the past 30 years, there has been significant focus on studying nutrient uptake within fluvial systems. However, there are still critical knowledge gaps about the controls of nutrient dynamics and how these processes scale. This study combined the results from traditional instantaneous nutrient addition experiments and sensor data averaged over ±5 days from the time of addition to determine mechanisms that affect nutrient dynamics in two contrasting streams within the same watershed, over almost …

Socioeconomic And Neuroanatomic Contributions To Language Performance In Children Born Very Preterm At Preschool And School Age, Rebecca E. Avila-Rieger

Psychology ETDs

Background: Children born very preterm are more likely to have difficulties with language acquisition and use that persist throughout childhood. Preterm birth occurs at a critical time in brain development and interrupts neurodevelopment, which has downstream implications for altered neural structure and function. Prematurity and socioeconomic status greatly impact language performance in children, but the neural substrates are poorly understood. Here the neural constituents of language performance are examined in select cortical and subcortical regions.

Methods: Fifty-one children born preterm (24-31 weeks) and 20 born full-term were seen at preschool (mean age = 47 months) and school age (mean age …
