The Global Extent Of The Grassland Biome And Implications For The Terrestrial Carbon Sink, A S. Macdougall, B Vanzant, J Sulik, S Bagchi, D Naidu, T O. Muraina, E. Hersch-Green

Michigan Tech Publications

Land cover data are commonly used to model the terrestrial carbon (C) sink, yet these data have wide margins of error that significantly alter estimates of global C storage. Here we demonstrate this data vulnerability in grasslands, which are critical to C cycling but whose estimated distribution has varied by >50 million km (3.5-42% of the Earth's terrestrial surface). Comparing multiple high-resolution land cover products with expertly annotated grassland data from six continents, we show sources of mapping error and discuss C implications based on 2023 United Nations (UN) FAO estimates. Past misidentification arose from inconsistent definitions on grassland identity …

Hie 337 Modern Russian History, Rhiannon L. Dowling

Open Educational Resources

The 19^th and 20^th centuries in Russia were a time of unprecedented creation and destruction. During this period the Russian Empire—arguably the most politically backward nation in Europe—transformed into the Soviet Union—the most radical modern political experiment in history. The life of the Soviet Union is itself bookended by the two most unlikely and unexpected moments in world history: the Russian Revolution at one end, and the collapse of the Soviet empire on the other. And decades after the Soviet Union’s collapse, experts are still debating what finally precipitated the sudden death of an empire that seemed for …

Characterization Of Social Media Use Patterns Among Hispanic/Latinx Dementia Caregivers And Its Impact On Mental Health, Sofia Mildrum Chana

ETDs from 2020-2029

Hispanic & Latinx (H&L) family caregivers of people living with Alzheimer’s disease and related dementias (ADRDs) experience high levels of stress that can negatively impact their mental health and may turn to social networking sites (SNS, commonly known as ‘social media’) for coping or social support. However, no research has yet examined how SNS use influences H&L caregiver mental health. The primary purpose of the present study was to characterize patterns of SNS use among H&L ADRD family caregivers and examine the associations between SNS use and caregivers’ mental health and well-being. Data for the present study come from the …

Exploring The Relationship Among Nurse-Specific Factors And Triage Accuracy In The Emergency Setting, Krisada Suamchaiyaphum

ETDs from 2020-2029

Triage is a critical function of emergency nursing practice, directly influencing patient safety, flow, and outcomes in the emergency department (ED). Despite widespread use of standardized triage training and resources, triage accuracy among ED nurses remains suboptimal. The purpose of this three-manuscript dissertation was to examine factors associated with triage accuracy in the ED setting. Manuscript One was an integrative literature review of 14 studies published between 2011 and 2021, with reported triage accuracy rates ranging from 59.3% to 82%. Primary factors associated with triage accuracy were: nurse-specific, patient, and work environment factors. Manuscript Two reported a retrospective study of …

The Influence Of The Mental Health Parity And Addiction Equity Act On Residential Behavioral Healthcare Facility Availability In The United States: A State-Level Analysis, Amanda Mellowspring

ETDs from 2020-2029

The need for accessible, quality behavioral healthcare (BH) has increased dramatically over recent decades. The availability of BH services for patients has long been complicated by high cost, lack of insurance coverage, and location accessibility. BH organizations face ongoing challenges to meet the demand for services including costs of operation, worker shortages, and navigating the payer landscape. The history of BH in the U.S. provides the foundation to conceptualize federal regulations and attempts at parity. Literature regarding federal legislation, such as the Mental Health Parity Addiction and Equity Act (MHPAEA), the Affordable Care Act, and Medicaid expansion; BH facilities and …

Development And Validation Of A Theoretically Informed Instrument To Measure The Antecedents Of Microbreaking Intentions (I-Mami) Of Procedural Healthcare Workers, Robin Riddle

ETDs from 2020-2029

ABSTRACT Work-related musculoskeletal disorders (WMSD) affect 77% of nurses and 60% of surgeons, exceeding rates in other occupational sectors and threatening healthcare workforce sustainability. Microbreaking is brief, strategic pause of 20 seconds to five minutes performed every 20 to 40 minutes during medical procedures. It has demonstrated effectiveness in reducing fatigue, improving accuracy, and lowering physiological stress markers without extending medical procedure duration. Despite this evidence, adoption remains limited, and no theoretically informed instruments exist to measure the behavioral determinants of microbreaking intentions among procedural healthcare workers. Investigators of this three-manuscript dissertation developed and established content and construct validity as …

Iterative Data Augmentation For Enhancing Deep Learning Performance With Limited Training Data, Avinash Singh

ETDs from 2020-2029

Deep learning models have demonstrated impressive performance across different domains; however, their effectiveness heavily depends on large, well annotated datasets. In practice, data are often limited in size, leading to overfitting, poor generalization, and degraded model robustness and performance. Moreover, conventional augmentation techniques are typically static in nature, lack adaptability during training, and can produce geometrically inconsistent or unrealistic mixed images. This dissertation addresses three major challenges in data augmentation and model generalization: (1) the scarcity of labeled data and limited dataset size, (2) the absence of adaptive mechanisms for dynamically adjusting learning parameters during training, and (3) the creation …

Development Of Salinomycin Analogs As Potential Anti-Cancer Agents, Pavan Goud Juluri

Theses and Dissertations

Salinomycin, a poly-ionophore antibiotic originally isolated from Streptomyces albus, exhibits antimicrobial activity against Gram-positive bacteria. Over the years Salinomycin has been studied in the effects it has on cancer, specifically cancer stem cells. Poly(ADP-ribose) polymerase (PARP) is an enzyme involved in DNA repair. Inhibiting PARP has been explored as a strategy in cancer treatment, particularly in cancers with defective DNA repair mechanisms, such as those with BRCA mutations. The benzo-thiazoles, and -imidazoles are identified as inhibitor scaffolds, which compete with nicotinamide in the binding pocket of human poly- and mono-ADP-ribosylating enzymes. Benzothiazole, and benzimidazole based compounds particularly with modification at …

Hard Hats And Second Chances: A Phenomenological Study Of Employer Support In Construction-Based Reintegration, Christofer M. Pacheco

USF Tampa Graduate Theses and Dissertations

This qualitative phenomenological study examines how formerly incarcerated individuals perceive and experience employer support during workplace reintegration in the construction industry. Although employment is widely recognized as a protective factor against recidivism, post-hire experiences from the perspective of justice-involved employees remain underexplored. Grounded in an interpretivist paradigm and informed by Social Support, Social Learning, and Identity perspectives, the study investigated how structure, self, and environment interact to influence retention, growth, and desistance.

Nineteen interviews were completed with six construction workers in New Mexico who had maintained employment for at least one year following incarceration. Through the use of Seidman’s three-interview …

Leadership, Learning and Counseling Faculty Publications and Presentations

This Children in Cities research project examines an approach to storying research that foregrounds collaborative meaning-making between educators and young children in their city. Through exploring how educators and young children might “think otherwise” about teaching, learning, and participation with history, Place noticing and entanglements between humans, more-than-human, and non-humans, three stories and a metaphor surface in the data. Drawing on three stories, metaphor is employed as an analytic and integrative device to deepen interpretation of lived experiences. Central to the methodology is a democratic orientation that seeks to reduce hierarchical boundaries, engaging children aged 3–5 as co-researchers in the …

Apolipoprotein E4 And Its Later-Life Health Effects On The Multiple Sclerosis Population, Dean Zeldich, Chia Hsin Cheng, Yi Guan, Sriman Narain, Bang-Bon Koo

Department of Neurology Faculty Papers

BACKGROUND AND OBJECTIVES: Multiple sclerosis (MS) is a chronic autoimmune disease causing neuroinflammation and neurodegeneration. The apolipoprotein E4 (APOE4) allele, a major genetic risk factor for late-onset Alzheimer's Disease, accelerates cognitive decline and neuroinflammatory processes, including blood-brain-barrier disruption. This study explores the impact of APOE4 on later-life health in MS patients using biomarkers from the UK Biobank.

METHODS: MS patients were grouped by APOE4 carrier status: MS-E4 and MS-nonE4. Age- and sex-matched non-MS controls (control-E4, control-nonE4) were included for comparison. Analyses assessed retinal nerve fiber layer thickness (RNFL) from optical coherence tomography (OCT), blood biomarkers, cognitive performance, and brain magnetic …

Triple-negative breast cancer (TNBC) is a prevalent breast cancer subtype with the lowest 5-year survival. Several factors influence outcomes, but their inherent molecular and cellular heterogeneity are increasingly acknowledged as crucial determinants. Here, we report on the spatio-molecular heterogeneity underlying TNBC tumors in a retrospective, treatment-naive cohort with differential prognoses (17 good prognoses [GPx] >15-year survival and 15 poor prognoses [PPx] < 3-year survival]) profiled using GeoMx Digital Spatial Profiler. Analyses reveal that epithelial and microenvironment (TME) states are transcriptionally distinct between groups. Invasive GPx epithelia show an increase in immune transcripts, with a more immune-rich TME (via IF). PPx epithelia, in contrast, are more metabolically and translationally active, with a mesenchymal/fibrotic TME. Pre-cancerous epithelia in PPx exhibit a presence of aggressiveness, marked by increased EMT signaling and complement activity. We identify distinct epithelial gene signatures for PPx and GPx that can accurately classify diagnostic samples and likely inform therapy.

Modulation Of The Cgas-Sting Inflammation Pathway In Mouse Models Of Accelerated And Slowed Aging, Benjamin David Heckman

ETDs from 2020-2029

Chronic sterile inflammation (inflammaging) is a core pillar of aging, and the cGAS-STING innate immune pathway has emerged as a key driver of this process. However, how this pathway intersects with systemic endocrine signaling remains poorly understood. Here, we investigated the intersection of endocrine signaling and cGAS-STING activation using two complementary mouse models with opposing lifespan phenotypes: a short-lived, liver-specific glucagon receptor knockout (LKO) mouse and a long-lived growth hormone-releasing hormone knockout (GHRH-KO) mouse. We demonstrate that despite presenting with a metabolically healthy phenotype, female LKO mice exhibited a significantly reduced lifespan. We link this premature mortality to a sex …

Examining Pain- Related Stigma And Sources Of Resilience In Children With Disorders Of Gut-Brain Interaction, Tolulope Adetayo

ETDs from 2020-2029

Background. Painful disorders of gut-brain interaction (DGBI) affect approximately one in five children. In addition to functional impairments, DGBI increase risk for felt stigma (FS) from providers, school personnel, family members, and peers. Children with DGBI may also belong to other minoritized groups that intersect with pain-related FS. However, little is known about how intersectionality impacts the stigma and pain experiences of youth. Further, little is known about the protective capabilities of psychosocial resources (e.g., social support and hope) against FS. Thus, the current study aimed to investigate the impact of FS and its potential moderators in a sample of …

Ultrafast Terahertz Spectroscopy And The Suppression Of Superconductivity In Strained Iron Selenide Below 1 Kelvin, Tracy Glen Hastings

ETDs from 2020-2029

We report on terahertz time-domain spectroscopy measurements of iron selenide thin films of various thicknesses grown on a magnesium oxide substrate, focusing on the frequency-dependent complex conductivity in the range of 0.25 - 7 THz. By an- alyzing films with and without an approximately 100 nm thick Se capping layer, we examined the role of oxidation in the suppression of superconductivity. X-ray photo- electron spectroscopy data confirmed that oxidation was effectively mitigated, yet the films exhibited insulating behavior down to 200 mK, a temperature range that has not been extensively studied in this system. Our results indicate that the suppression …

Posterior Cerebellar Lobe Deviations And Social Cognition In Individuals With Psychosis And Their Unaffected Relatives, Andreea Maria Stanica

ETDs from 2020-2029

Social cognition deficits observed in psychotic disorders contribute to functional impairments. The cerebellum has been identified as a critical brain region involved in social cognitive processes, but the relationship between cerebellar structural deviations and social cognition in individuals with psychosis (probands) and their unaffected relatives remains unclear. Using normative modeling, this study examined cerebellar volume deviations in probands and their unaffected first-degree relatives and investigated associations with social cognitive and motor performance. Probands exhibited significant theory of mind deficits compared to relatives. Probands showed negative deviations in anterior cerebellar lobe relative to the norm, whereas relatives did not. Deviations in …

Exploring Criminality Through A Developmental Lens: Contextual Effects From Childhood To Emerging Adulthood, Abigail Jeanette Anderson

ETDs from 2020-2029

Adolescent delinquency is a key predictor of later criminal behaviors and is associated with negative outcomes across education, employment, and health. Despite extensive research, gaps remain regarding the interplay of individual- and context-level factors in the development of delinquency, as well as the reliance on cross-sectional or retrospective designs. Guided by a social-ecological framework, the present dissertation examines how family, school, and neighborhood contexts interact with individual behaviors to shape pathways toward delinquency and adult criminality across childhood, adolescence, and early adulthood. The first study investigated the cascading effects of paternal engagement, parental aggravation, and early child behavior problems in …

Reproductive System Variation In Tropical Red Macroalgae, Taylor M. Williams

ETDs from 2020-2029

The reproductive system encompasses the relative rates of sexual versus clonal reproduction and is responsible for partitioning genetic diversity within and among populations. However, the quantification of these rates remains limited in natural populations and has primarily focused on animals and angiosperms. This knowledge gap is particularly acute among tropical macroalgae. This dissertation addresses this by focusing on the cryptogenic invader Chondria tumulosa in the Papahānaumokuākea Marine National Monument and the invasive species Acanthophora spicifera across the Hawaiian Archipelago, Australia, and Guam. For Chondria we developed nine microsatellite loci and found a dominance of tetrasporophytes, high clonal rates, and strong …

Amino Acid Pet Tracers For Cancer Imaging And Response Assessment, Ugur Akca

ETDs from 2020-2029

Triple-negative breast cancer (TNBC) and high-grade glioma (HGG) pose significant diagnostic and therapeutic challenges due to their aggressive biology and the limitations of [¹⁸F]FDG PET, which suffers from nonspecific uptake in inflammatory tissues, complicating differentiation of viable tumor from treatment-related effects. Computed Tomography, while strong for structural changes, has limited soft tissue contrast for distinguishing tumor from inflammation, and Magnetic Resonance Imaging, despite superior soft tissue resolution, struggles with differentiating active tumor from post-treatment changes like edema or necrosis due to nonspecific enhancement. These challenges highlight the necessity for complementary and advanced imaging strategies for improved diagnosis and monitoring. This …

Bidirectional Effects Of Transcutaneous Auricular Vagus Nerve Stimulation On Insomnia And Brain Health In Breast Cancer, Melissa Van Trang Do

ETDs from 2020-2029

Breast cancer remains the most frequently diagnosed cancer among women worldwide, with over 2.3 million new cases annually. While advances in treatment have improved survival, many women continue to suffer from persistent insomnia, fatigue, anxiety, depression, and cognitive dysfunction that collectively impair quality of life and recovery. These interrelated symptoms share common biological underpinnings, including autonomic dysregulation, vagal withdrawal, and chronic inflammation. Transcutaneous auricular vagus nerve stimulation (taVNS) is a non-invasive, bioelectronic therapy that modulates afferent vagal pathways via auricular branches of the vagus and trigeminal nerves. By engaging central autonomic and neuroimmune circuits, including the nucleus tractus solitarius and …
