This study examined the relationship between naturally occurring farm animal interactions and overall well-being among rural adults living in the central Appalachian region, specifically western Maryland, south-central Pennsylvania, and the eastern panhandle of West Virginia. A cross-sectional, correlational design was used to compare adults with at least five hours of naturally occurring farm animal contact per week to those with less than one hour of contact per week. Overall well-being was measured with the PERMA-Profiler, and heart rate variability (HRV) was measured using wearable devices as a physiological indicator of autonomic health. Grounded in polyvagal theory, the biophilia hypothesis, and …
Empowering Women: Understanding Neurological Changes In The Aging Brain, Joy Mckenzie
Empowering Women: Understanding Neurological Changes In The Aging Brain, Joy Mckenzie
InnovateHER Meeting 2026
Women tend to have more neurological changes than men as they age starting in their mid-30s (Mosconi, 2024). While aging is a natural process, the neurological changes can impact a woman’s personal and professional quality of life (Faubion et al., 2023; Gravini, 2023). For years, women’s neurological symptoms have been ignored by being told that their experiences are normal and just a part of life (Haver, 2025). That narrative is starting to shift with the increased awareness of changes specific to women. There are resources to assess cognitive changes such as memory, processing speed, and word finding and strategies to …
Patterns And Drivers Of Cladocera Community Structure In The Black Sea, Elena Bisinicu, Luminita Lazar
Patterns And Drivers Of Cladocera Community Structure In The Black Sea, Elena Bisinicu, Luminita Lazar
Turkish Journal of Zoology
Cladoceran community dynamics were examined in the Romanian sector of the Black Sea during the warm seasons of 2013– 2020, using Marine Reporting Units (MRUs) to evaluate spatial heterogeneity across transitional, coastal, and marine waters. Analyses of density, biomass, mean individual biomass (MIB), and species composition revealed interannual fluctuations superimposed on strong nearshore–offshore gradients, with higher values in transitional and coastal MRUs. The assemblage was consistently dominated by Pleopis polyphemoides and Penilia avirostris, which together accounted for most of the total abundance and biomass. Multivariate analysis identified significant differences in taxonomic composition across MRUs and years, while correlation analyses highlighted …

The Effect Of Spatial Scale Of Habitat On Abundance Of Roe Deer (Capreolus Pygargus) And Water Deer (Hydropotes Inermis Argyropus) During Summer In South Korea, Naeyoung Kim, Hyejin Kim, Hyoun-Gi Cha, Hyun-Su Hwang
Turkish Journal of Zoology
Understanding species-specific habitat preferences provides essential ecological information about interactions among habitat components. In South Korea, roe deer (Capreolus pygargus) and water deer (Hydropotes inermis argyropus) are the dominant large herbivorous mammals of the family Cervidae. The increasing populations of these species have led to ecological and economic challenges. Therefore, we investigated the effects of spatial scale characteristics on the habitat preferences of roe deer and water deer. From June to August each year between 2021 and 2023, we calculated the relative abundance index (RAI) using camera-trap data and analyzed patch characteristics in the study area using remote sensing techniques, …
Global Health Financing Of Diagonal Interventions: Building Resilient And Sustainable Health Systems In Sub-Saharan Africa, Lucy Kim
Master in Public Policy Theses
Background: Global health financing has historically prioritized disease-specific “vertical” programs over broader “horizontal” strengthening of general health systems. Vertical programs in HIV have led to unprecedented reductions in mortality worldwide, but HIV remains a significant public health threat in sub-Saharan Africa, where vertical strategies have long been criticized for creating fragmented health systems. In response, global health strategies have shifted towards combining vertical investments with broader horizontal activities, commonly referred to as “diagonal” programming. While evidence suggests that diagonal programming has the potential to create more resilient and sustainable health systems, evaluating its value for money is challenging due to …
The Impact Of Tgfβ Conditioning And Socs3 Expression On Cytokine Signal Transduction And Inflammatory Gene Expression In Fibroblasts, Morgan Anderson-Crannage
The Impact Of Tgfβ Conditioning And Socs3 Expression On Cytokine Signal Transduction And Inflammatory Gene Expression In Fibroblasts, Morgan Anderson-Crannage
NYMC Student Theses and Dissertations
Inflammation is a major driver in many aspects of recessive dystrophic epidermolysis bullosa (RDEB) pathology, including impaired wound healing, fibrosis, and potentially cutaneous squamous cell carcinoma development. Fibroblasts, as key stromal cells in the dermis, are responsible for orchestrating inflammatory responses through the secretion of cytokines and chemokines upon stimulation with IL-1α or IL-6. Suppressor of Cytokine Signaling 3 (SOCS3) functions as a negative feedback regulator of cytokine signaling and has emerged as a key modulator of inflammatory responses in immune cells and fibroblasts. Transforming Growth Factor Beta (TGFβ), a known driver of fibrosis in RDEB, has been implicated in …
The Heterogeneous Response Of Astrocytes In Different Brain Regions Under Metabolic Stress, Pawan Kumar Thapaliya
The Heterogeneous Response Of Astrocytes In Different Brain Regions Under Metabolic Stress, Pawan Kumar Thapaliya
USF Tampa Graduate Theses and Dissertations
Astrocytes play a central role in maintaining ionic homeostasis, neurotransmitter clearance, and brain en-ergy metabolism. Their excitability, reflected in activity-evoked intracellular sodium (Na+, [Na+]i) and calcium (Ca2+,[Ca+]i) dynamics, is increasingly recognized as a critical determinant of neuronal function and vulnerability, particularly under metabolic stress. Despite their importance, the mechanisms underlying astrocytic ionic signaling and its regional heterogeneity remain incompletely understood. In this thesis, I developed detailed computational and biophysical models to investigate astrocytic Na+ and Ca2+ dynamics, their bioenergetic consequences, and the roles of key ion transporters under physiological and metabolically stressed conditions, validating the models against experi- mental data. …
Investigating Changes In The Stable Isotopic Composition Of Juniperus Osteosperma Over 34,000 Years Of Climatic Shifts, Lisa S. Garcia
Investigating Changes In The Stable Isotopic Composition Of Juniperus Osteosperma Over 34,000 Years Of Climatic Shifts, Lisa S. Garcia
Biology ETDs
Isotopic compositions of plants from the past provides empirical evidence for paleoclimatic shifts and plants physiologically response. This study used Neotoma paleomiddens (fossilized debris piles) collected from Death Valley National Park, which contained preserved abundant plant materials. These middens range from modern to >35,000 years and capture different climatic events in Earth history. Employing Juniperus osteosperma (Utah Juniper) leaves found in middens, I investigated variation in carbon and nitrogen stable isotopic composition. To help interpret paleomidden results, we used modern field and herbaria samples of Juniperus from a spatial gradient stretching across their geographic range. Results showed δ 13C …
Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez
Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez
Psychology ETDs
Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …
What Is Mine, Yours And Ours: Bodily Metaphor And Neuropsychology, Alicia K.E Parham
What Is Mine, Yours And Ours: Bodily Metaphor And Neuropsychology, Alicia K.E Parham
Art Theses and Dissertations
Mapping the landscape of the brain has taken human lifetimes to navigate, both structurally to understand how our biological functions interact and functionally as our thoughts and emotions shape our existence. Neurological stimulus and response inform our reality, shape our thinking, and affect our bodies in profound physiological ways. Our nervous system acts as a bridge from what we experience physically to what we feel emotionally, through the sending of electrical signals to all parts of our body.
My art practice explores the interactions of neuroscience with outside stimuli. It is rooted in the personal: learning that a neurological condition …
Characterizing A Potential Cbp/P300 Histone Acetyltransferase Homolog In Tardigrade Germline Specification And Development, Brittney Michelle Hartshorn
Characterizing A Potential Cbp/P300 Histone Acetyltransferase Homolog In Tardigrade Germline Specification And Development, Brittney Michelle Hartshorn
Honors Projects
Germline specification is a fundamental process that ensures the proper development of germ cells. Germline specification occurs either through germ cell determinants maternally inherited through the mechanism of preformation or through induction, where cell interaction and epigenetic modifications direct specification. Determining how these mechanisms evolved and diverged remains an important question in developmental biology. Despite research on germline regulation in model organisms such as Caenorhabditis elegans or Drosophila melanogaster, such regulation remains poorly understood in many other animal groups. Tardigrades are an emerging model system for investigating developmental mechanisms due to their phylogenetic placement and experimentally tractable embryos. CBP/P300 is …
The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly
The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly
Health, Exercise, and Sports Sciences ETDs
Hypoxic environments, resulting from decreased atmospheric partial pressure of oxygen, reduce oxygen availability in the blood and tissues, leading to a mismatch between supply and demand. This elicits several physiological adaptations and may influence bone metabolism. Although evidence suggests that hypoxia can modulate bone remodeling through hypoxia-inducible pathways, findings remain mixed, with most data derived from chronic hypoxic exposures in animal and cell culture models. Exercise, an essential stimulus for bone health, may exacerbate hypoxic stress; however, the skeletal response to acute hypoxic exposure combined with exercise remains unclear. We propose that intermittent exercise in hypoxia may increase negative markers …

The Development And Evaluation Of An Automated Tactical Tillage Tool To Identify And Control Weeds In Row-Crop Production Systems Using Vision-Based Machine Learning., Clara Anne Cobb
Theses and Dissertations
Controlling in-field weeds in row-crop production systems is vital to the success of the operation. To control weeds, most producers use combinations of weed control strategies, including tillage and herbicide applications. Cotton production operations across the country have been trending toward conservation tillage practices in an effort to minimize soil disruption and maintain crop residues on the soil surface. This practice, in addition to the adoption of herbicide-tolerant cotton varieties, has encouraged more use of chemical herbicides. The overuse of these herbicides has resulted in an increase in herbicide-resistant weeds, making weed control difficult for farmers. This research aimed to …

Exploring The Biological Basis For Exercise Neuroprotection In Parkinson’S Disease: A Cross-Sectional Study Of Exercise And Physical Activity On Inflammatory Cytokines And Neurotrophins, Leah Isabelle P. Alegre, Jacob M. Brewer, Adeline Florschutz, Kate E. Hamiltonthompson
UNLV Theses, Dissertations, Professional Papers, and Capstones
Regular exercise and physical therapy are known to increase production of neurotrophins, including brain-derived neurotrophic factor (BDNF), and anti-inflammatory cytokines. These changes combine to theoretically protect and slow the progressive loss of neurons in Parkinson’s disease (PD). The purpose of this study was to examine the effect of exercise and physical activity on various anti-inflammatory and pro-inflammatory cytokines and neurotrophins in people with PD (PwP). This was a cross-sectional design involving PwP (n=37), aged 43-85 years, who participated in two 30-minute bouts of exercise (with brief rest breaks during and pre/post blood draws) separated by a week. Measures collected prior …
Postural And Load Dependent Modulation Of Lower Limb H-Reflex Excitability After Stroke, Daniel Bamiro, Matthew Berdiago, Ethan Hunter, Tia Nguyen
Postural And Load Dependent Modulation Of Lower Limb H-Reflex Excitability After Stroke, Daniel Bamiro, Matthew Berdiago, Ethan Hunter, Tia Nguyen
UNLV Theses, Dissertations, Professional Papers, and Capstones
Purpose/Hypothesis
Leg stiffness is regulated by reflexive, intrinsic, and passive mechanisms, which are influenced by posture, body weight loading, and motor task demands. After a stroke, the capacity to modulate these mechanisms is often compromised. The H-reflex is a widely used electrophysiological tool to assess the excitability of the Ia afferent pathway within spinal circuitry. Although prior studies in healthy individuals have examined limb loading effects, results have been variable, and the role of postural and loading changes during standing remains underexplored, particularly in individuals post-stroke. This study investigated how different postural and limb loading conditions, specifically prone, standing, and …
Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam
Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam
UNLV Theses, Dissertations, Professional Papers, and Capstones
This secondary analysis study evaluated the effectiveness of Cognitive Stimulation Therapy (CST) on quality of life (QoL), depressive symptoms, and cognitive function in 108 community-dwelling older adults with cognitive impairments, including dementia. Outcomes involved Quality of Life (QoL) measured by the Quality of Life in Alzheimer’s Disease (QoL-AD), symptoms of depression by the Cornell Scale for Depression in Dementia (CSDD), and cognitive function using the Saint Louis University Mental Status (SLUMS). After the CST, significant improvements were observed in QoL (p = .004), depressive symptoms (p = .002), and cognitive function (p < .001), with small effect sizes. Additionally, a significant interaction between sex and dementia diagnosis status was found in predicting cognitive changes, suggesting that the relationship between dementia diagnosis and cognitive improvement differs by sex. No between-group differences were found for QoL or depression. Findings support CST as a multidimensional, non-pharmacological intervention that improves cognitive, psychological, and social outcomes. Although effects were small, consistent improvements are clinically meaningful given the progressive nature of dementia. This study extends existing literature by demonstrating CST’s effectiveness in a community-based setting and reinforces its alignment with occupational therapy’s emphasis on participation and holistic care. Results highlight the need for early intervention and expanded access to CST programs to enhance quality of life in this population.

Exploring Health Insurance’S Role In Chronic Disease Management Among Hispanics, Romelyn Dones
Exploring Health Insurance’S Role In Chronic Disease Management Among Hispanics, Romelyn Dones
Seton Hall University Dissertations and Theses (ETDs)
This qualitative study examined how insured non-English- and English-speaking Hispanic adults perceive the role of health insurance in the management of chronic disease. Chronic conditions remain a leading cause of morbidity in the United States, and although prior research suggests that insurance coverage improves access to care, it does not always enhance how individuals understand or utilize support for chronic disease management. Limited research has explored how individuals with chronic conditions interpret the role of insurance in their daily self-management practices, particularly among Hispanic populations. Guided by Andersen’s Behavioral Model of Health Services Use, this study explored how contextual, enabling, …
Protecting Galápagos’ Marine Ecosystems: Biosecurity And Network Design Against Invasive Species From Tourist Vessels, Marnie L. Campbell, T.U. Le, Chad Hewitt
Protecting Galápagos’ Marine Ecosystems: Biosecurity And Network Design Against Invasive Species From Tourist Vessels, Marnie L. Campbell, T.U. Le, Chad Hewitt
Research outputs 2022 to 2026
The modern world is characterized by high connectivity, enhancing economic productivity, and global communication, but outpacing our ability to manage its consequences. This connectivity increases the risk of pathogen, pest, and invasive species transmission. In the Galápagos islands, Ecuador, tourist vessel networks operate with limited restrictions and connect high conservation value locations, boosting tourism and the economy. These vessels frequently travel between multiple islands, leading to moderate connectivity and high vessel promiscuity. To prevent the spread of invasive species via these vessels, we propose a biosecurity system that combines social network tools with risk management frameworks that balances environmental protection …
