Understanding Administrator Approaches To Trauma-Informed Care: Findings From A Mixed Methods Study, Megan Coalwell

Theses and Dissertations

Traumatic events during childhood have been termed adverse childhood experiences (ACEs). Experiencing traumatic events or ACEs is common for school-aged children. Research reports indicate that as many as two out of three children will experience at least one traumatic event by the time they are eighteen. The negative effects of experiencing trauma are well documented. Trauma can lead to long-term outcomes in adults such as chronic health problems, mental health problems, substance misuse, and even early death. During childhood, it can lead to internalizing and externalizing problems, as well as difficulties in school. Trauma-Informed Care (TIC) is an approach to …

An Active Quasi-Circulator Ic And Technique For 1-255 Mhz Resonance-Based Spectroscopic Impedance Plethysmography, Sharisse Poff

Theses and Dissertations

Impedance measurement is a promising avenue for noninvasive glucosemonitoring. Specifically,resonance-basedimpedancemeasurements exhibit good correlation with glucose levels at excitations from tens of MHztoover 100 MHz. Additionally, plethysmographic impedance measurements are needed to separate arterial blood signals, which contain strongerglucose information, frominterstitialfluidsignals. Weanticipate that plethysmographic measurements across a range of frequencies— spectroscopic plethysmography—at excitations from tens to over 100 MHz could enable resonance-based monitoring with higher selectivity for arterial glucose than previous work. Afour-point impedance measurement circuit is designed, and its ability to measure constant and periodically time-varying impedance is demonstrated. This circuit presents high impedance to the device-undertest (DUT), which fails …

Population Dynamics Of Feral Hemp (Cannabis Sativa L.) Across Illinois, Bryan Scott Foster

Dissertations

Hemp (Cannabis sativa L.) is an historically cultivated species re-emerging in modern agriculture due to its utility as a fiber, grain, and cannabinoid crop. While industrial hemp refers to cultivated varieties bred for specific agronomic traits and legally defined by low tetrahydrocannabinol (THC) content, feral hemp, often called "ditch weed", represents escaped or naturalized populations descended from historical cultivation. These unmanaged populations persist and spread in disturbed habitats across North America, particularly in the Midwestern U.S., raising ecological and agronomic concerns due to their potential for genetic contamination, invasive behavior, and interactions with native species and agricultural systems. The overall …

Modeling Copper Biogeochemistry In Continental Environments: 0 – 93 °C, Paul Goldsborough Helfrich

Graduate Theses & Non-Theses

Microbiomes are intertwined with copper chemistry through both toxin and trace nutrient interactions. We produced and examined nineteen metagenomes from a creek recovering from historic copper mining to investigate how anthropogenic contamination shapes microbial community structure and functional potential. We then incorporated the metagenomic profiles and concurrently collected geochemical context into multivariate models to examine correlations between habitat geochemistry and microbial ecology. Residual copper and wastewater inputs alter stream habitability across seasonal gradients. We complimented initial analyses with new insights from high temperature environments. Combined dissolved inorganic carbon (DIC), temperature, pH, and silica stress constrain photosynthesis in hydrothermal features. Geochemical …

The Molecular And Behavioral Characterization Of The Murine Cre – Loxp Skeletal Muscle Synthesized Bdnf Knockout Model, Asha E. Rustad

All NMU Master's Theses

Brain derived neurotrophic factor (BDNF) is a neurotrophin essential for supporting the growth, differentiation, and health of neurons within the central and peripheral nervous systems. BDNF is also a member of the myokine family, where muscle synthesized-BDNF (msBDNF) is thought to facilitate the crucial bi-directional communication between the motor neuron and the muscle fibers it innervates. Since 2008, the Ottem Laboratory has investigated the role of msBDNF by employing Cre/LoxP recombinase technology to selectively delete the BDNF coding region within skeletal muscle of mice. This approach generates animals with either heterozygous or homozygous deletions of msBDNF, as well as BDNF …

Patterns And Continuity: Documenting African American History In Carbon County, Utah, And The Roots Of Racial Terror Lynchings In American Society, Michael L. B. Forvil

Undergraduate Honors Theses

This thesis explores the history of African Americans in Carbon County, Utah, through the lens of racial terror lynching, community memory, and migration. Anchored in the story of Robert Marshall, a Black man lynched in Price, Utah, in 1925, the project considers how racial violence reached beyond the American South and how such acts have been neglected in public memory. Drawing on family history research, census records, historical newspapers, and the work of the Equal Justice Initiative (EJI), this work contextualizes Marshall’s death within broader patterns of racial terror lynchings that shaped African American migration from the South during the …

Evaluation Of A Forest Restoration Strategy On Small Mammals In Southern Pine Ecosystems, Gage R. Grantham, Jessica L. Glasscock, Christopher M. Schalk, Kathryn R. Kiid, Reuber Antoniazzi

Electronic Theses and Dissertations

Industrial forestry replanted historic native pine forests (e.g., longleaf pine [Pinus palustris] and shortleaf pine [Pinus echinata]) to homogenous, high-density plantations consisting of native off-site species (e.g., loblolly pine [Pinus taeda]) after intensive harvesting for wood products. The contemporary forest structure that remains, consisting of off-site overstory compositions, can potentially serve as an ecological bridge to facilitate a gradual transition to a more desirable canopy species, thereby conserving biodiversity and ecosystem function. Understanding disturbance-sensitive small mammal communities from restoration strategies (retention) can help achieve long-term management goals for ecosystem conservation across larger scales. I …

Using Silvopasture To Mitigate Heat Stress In Grazing Beef Cattle, Sydney L. Lofland

Electronic Theses and Dissertations

This study evaluated the impact of silvopasture on mitigating heat stress in grazing beef cattle by comparing physiological and behavioral responses between shaded and non-shaded pastures. Twenty-two multiparous cows were monitored over a 20-day summer trial in East Texas. Data were collected on respiration rate, heart rate, heat stress scores, and behaviors including eating, ruminating, walking, and resting. Average respiration rates and behavior proportions did not differ significantly between treatments. Afternoon periods showed peak physiological stress across all cattle, but silvopasture appeared to buffer extreme responses. Although limitations such as data gaps and a shortened trial impacted interpretation, findings suggest …

Retinal Vascular Dysfunction In The Mthfr(677c>T) Mouse Model Of Cerebrovascular Disease, Alaina M Reagan, Michael Maclean, Travis L Cossette, Gareth R Howell

METHODS: Morphology and function of retinal vasculature and neurons were assessed using in vivo imaging, immunohistochemistry, and pattern electroretinography. RNAscope and proteomics were employed to determine Mthfr gene expression and differential protein expression in mice carrying Mthfr

RESULTS: Mice show age- and sex-dependent retinal vascular deficits, displaying similarities to previously published brain data. Mthfr is widely expressed and co-localizes with vascular cell markers. Proteomics identified common molecular signatures …

Mitochondrial Complex I Deficiency Induces Alzheimer's Disease-Like Signatures That Are Reversible By Targeted Therapy., Huanyao Gao, Kate Jensen, Jarred Nesbitt, Mark Ostroot, Gregory Cary, Jesse Wiley, Sergey Trushin, Jens O Watzlawik, Wolfdieter Springer, Alexander Galkin, Priyanka Baloni, Cory Funk, Eugenia Trushina

Faculty Research 2025

INTRODUCTION: Mitochondrial dysfunction is implicated in Alzheimer's disease (AD), but whether it drives AD-associated changes is unclear. We assessed transcriptomic alterations in the brains of Ndufs4

METHODS: Cortico-hippocampal tissue from Ndufs4

RESULTS: Knockout of Ndufs4-mediated mtCI deficiency disrupted mitochondrial homeostasis, energy metabolism, and synaptic gene expression, recapitulating transcriptomic signatures of AD. CP2 treatment partially reversed these changes, with female Ndufs4

DISCUSSION: Loss of mtCI activity alone is sufficient to induce AD-like molecular changes in the brain, independent of amyloid beta or phosphorylated tau. CP2-mediated rescue highlights the potential of targeting mitochondria as a therapeutic strategy for AD. Sex-specific responses suggest …

Faculty Research 2025

Many SARS-CoV-2 patients experience chronic pulmonary symptoms and long-term inflammation despite viral clearance. While these clinical manifestations have been linked to the dysregulation of the adaptive immune response, the underlying immunopathology remains poorly understood due to a lack of suitable animal models. To investigate long-term pulmonary consequences of SARS-CoV-2 infection, we used a genetic cross of 129 mice and C57BL/6 (B6)-K18-hACE2 transgene mice, a model previously shown to survive infection. 129xB6-K18-hACE2 mice or littermate controls were infected with a low dose (5 × 10² PFU) of ancestral SARS-CoV-2. Complete viral clearance and full recovery from weight loss …

Faculty Research 2025

Pathogenic variants in the neuronal Na⁺/K⁺ ATPase transmembrane ion transporter (ATP1A3) cause a spectrum of neurological disorders including alternating hemiplegia of childhood (AHC). The most common de novo pathogenic variants in AHC are p.D801N (∼40 % of patients) and p.E815K (∼25 % of patients), which lead to early mortality by spontaneous death in mice. Nevertheless, knowledge of the development of clinically relevant neurological phenotypes without the obstacle of premature death, is critical for the identification of pathophysiological mechanisms and ultimately, for the testing of therapeutic strategies in disease models. Here, we used hybrid vigor attempting …

Evaluating Quadrupedal Locomotion In Bats: A Geometric Morphometric Comparison Of Vertebral Adaptations Across Mammals, Jessica Upham

Electronic Theses and Dissertations

Flight is the primary locomotion of bats, while quadrupedal locomotion is not often observed and is widely variable among bats. Frugivorous bats in Pteropodidae are more efficient climbers than frugivorous bats in Phyllostomidae and insectivorous bats in Vespertilionidae, while phyllostomids and vespertilionids are better at walking on horizontal surfaces. The aim of this study is to investigate whether bats with differing modes of nonflight locomotion also exhibit disparity in thoracolumbar vertebral morphology. Using geometric morphometrics, we compared the thoracolumbar vertebral shapes of these bat families with other terrestrial and arboreal mammals. The results revealed distinct vertebral shapes among bat families …

Limited data exist on the methods employed to use RWD to measure the effects of deprescribing. To describe methodological approaches used in observational studies of deprescribing medications in older adults, we conducted a systematic review in Medline for observational studies published in English (January 1, 2000, to September 14, 2023) that examined the health effects of medication deprescribing in older adults. We described study characteristics and methods, focusing on the operationalization of deprescribing as an exposure and potential time-related biases. …

Mindfulness As A Protective Factor In Women’S Sexual Health, Shana Byerley

Electronic Theses and Dissertations

Many women who experience physical health complaints also report sexual dysfunction across a variety of domains including decreased arousal, desire and satisfaction. Although there are well-established connections between disease-specific populations and sexual dysfunction, less research has focused on women who experience somatic symptoms more broadly. Similarly, mindfulness as a treatment intervention has been applied across many facets of sexual functioning, but mindfulness as a trait characteristic has been less explored in its connections with generalized somatic complaints. Further, the within-domain interactions between facets of mindfulness and domains of sexual dysfunction have not been previously explored. Using data from an online …

Electrochemical And Electrocatalytic Properties Of Screen-Printable Carbon Inks Featuring Pyridinic Nitrogen-Containing Polymeric Binder, Albert Sam Junior

Electronic Theses and Dissertations

Screen-printable conductive inks have been widely applied to prepare electrodes for electrochemical sensing. These inks generally consist of conductive metal or carbon particles, solvents, and polymeric binders. Low-cost, carbon-based, screen-printable conductive inks are especially popular. However, screen-printed carbon electrodes (SPCEs) must often be modified after they are printed to impart the necessary characteristics (e.g., sensitivity, selectivity, stability) for the desired application. For example, nitrogen-doping of SPCEs, especially in ways that introduce pyridinic or pyrrolic nitrogen species, can impart electrocatalytic properties towards reduction of O₂, H₂O₂, and CO₂. While our previous work done …

Raptors As Secondary Dispersers Of Mycorrhizal Fungal Spores, Joseph Anderson

Electronic Theses and Dissertations

Animals aid fungal dispersal by consuming fruiting bodies (e.g., truffles) and depositing spores elsewhere. Predators can act as secondary dispersers by preying on small mammals that eat truffles, although it is unclear how this dispersal may vary among species of raptors (hawks and owls) and fungal taxa. We experimentally fed four truffle taxa (with spores varying in size and wall thickness) to six raptor species (with differing gut morphology and acidity) to assess how spore viability and retention time may change between raptor casts and feces. Viability in smaller spores was more negatively affected by acidity compared to larger spores …

Hierarchy In Sensation: Exploring The 40 Hz Auditory Steady State Synchrony In The Primary Auditory And Prefrontal Association Cortices, Deepshila Gautam

Electronic Theses and Dissertations

Auditory processing begins in the cochlea and ascends through brainstem relays to the cortex, where sound features with increasing complexity are encoded. The 40 Hz auditory steady-state response (ASSR) reflects induced gamma synchrony shaped by local cortical circuit dynamics. Disrupted 40 Hz ASSR is a consistent finding in schizophrenia, linked to N-methyl-D-aspartate receptor (NMDAR) hypofunction in inhibitory interneurons, making it a promising translational biomarker. While multiple ASSR generators have been identified, it is not known if these are redundant or represent unique activity. This dissertation investigates regional differences in 40 Hz ASSR across two principal generators: the primary auditory cortex …
