The Presence Of Orthorexic Eating Behaviors In Students Studying Health Sciences, Sophia Weiner

West Chester University Graduate Theses, Dissertations, and Final Projects

Orthorexia nervosa is a novel type of disordered eating characterized by a hyper fixation on the consumption of clean, healthy, and morally pure foods as delineated by the individual (Dunn & Bratman, 2016). Previous studies have suggested that individuals studying physical health-related subjects such as nutrition and exercise science endorse more orthorexia nervosa symptoms than those in non-physical health-related areas (Malmborg et al., 2017; Plichta & Jezewska-Zychowicz, 2019). The present study sought to explore the relationship between college major, gender, and levels of body appreciation in the frequency of orthorexia nervosa symptomatology. It also aimed to assess orthorexia nervosa's relationship …

Turning To The Sacred: The Role Of Religious/Spiritual Coping In Psychological Outcomes Of Childhood Interpersonal Trauma, Vanessa S. Tomasik

College of Graduate Studies: Theses & Dissertations

Adverse Childhood Experiences (ACEs) are widespread and associated with significant and lasting psychological consequences, including posttraumatic stress symptoms (PTSS) and dissociation. Much of the existing literature has focused on adult trauma or narrowly examined childhood abuse and neglect, with comparatively limited attention given to other forms of childhood adversity such as witnessing intimate partner violence, parental separation, or household dysfunction. As a result, the differential psychological impact of distinct types of ACE exposure (i.e., maltreatment vs. household dysfunction) remains insufficiently understood. Emerging literature on coping identifies religious and spiritual (R/S) coping as an important factor in trauma adaptation. Positive R/S …

Sexual Di(Et)Morphism: Using Experimental Evolution To Test Whether Resource Partitioning Promotes Divergence Of The Sexes In Drosophila Melanogaster, Owen A. Jamieson

Theses and Dissertations (Comprehensive)

Sexual dimorphism has been a long-studied phenomenon in the field of evolutionary biology. Usually, these differences in morphology, physiology and/or behaviour between the sexes are studied through the parsimonious lens of sexual selection. However, there are natural history cases where this lens does not seem applicable. Some species show sex specific morphological traits whose presence may not be due to a direct benefit to reproduction, but a difference in how each sex interacts with the environment and differing selective pressures from the environment on either sex. Darwin even brought up examples of this kind of dimorphism and pondered their existence, …

Nourishing Births: A Program Evaluation Proposal For Community-Based Nutrition Education, Food Access, And Garden Engagement Among Black Birthing People, Naa Deedei-Vera Hammond

Master's Projects and Capstones

Black birthing people in the United States continue to experience unequal maternal health outcomes, shaped in part by racism and barriers to nutritious food, culturally relevant health education, and supportive community spaces. While prenatal nutrition education and food assistance programs can provide important resources, information alone cannot address the challenges many people face when trying to access healthy and affordable food during pregnancy. The Nourishing Births Initiative is a proposed community-based maternal health program designed to respond to these needs by bringing together prenatal nutrition education, help connecting to food resources, community gardening, and peer support for Black birthing people …

Knowledge, Attitudes, And Practices (Kap) Of Parents Regarding The Prevention And Control Of Childhood Iron Deficiency Anemia In Egypt: A Cross-Sectional Study, Omnia Soliman

Theses and Dissertations

Childhood Iron Deficiency Anemia (IDA) remains a major public health challenge in Egypt, where its persistently high and rising prevalence carries substantial consequences for child growth, cognitive development, immunity, and long-term health outcomes. Globally, approximately 40% of children aged 6–59 months are affected by anemia (World Health Organization, 2025), and Egypt mirrors this burden, with national data showing a worsening trend in recent years. In Egypt, national strategies have traditionally focused on biomedical interventions such as iron supplementation and food fortification, while less attention has been directed toward behavioral and household-level determinants, particularly parental knowledge, attitudes, and practices (KAP) related …

Analysis Of U.S. Army Body Composition Policies: Implementation Effectiveness And Recommendations For Policy Enhancement At Brooke Army Medical Center, Michael L. Rizzo

Doctor of Nursing Practice (DNP) Manuscripts

US Army body composition policies (AR 600-9 and recent directives) are essential for military readiness, injury prevention, and force health protection, yet implementation gaps persist, particularly with the 2026 Department of Defense (DoD)-mandated waist-to-height ratio (WHtR < 0.55) transition. This DNP project evaluated policy implementation effectiveness at Brooke Army Medical Center using the W.K. Kellogg Foundation Logic Model and CFIR 2.0 framework. Analysis of 2022–2025 de-identified administrative data and 16 stakeholder questionnaires identified ≥10 implementation gaps, including low awareness of new standards and workload impacts. The project developed 8 evidence-based recommendations and an implementation roadmap to improve compliance, optimize resources, reduce administrative burden, and strengthen military readiness.

Implementing Updated Npo Guidelines For Inpatient Procedures, Yasamin Ghanivand

Doctor of Nursing Practice (DNP) Projects

Background: Nil per os (NPO) guidelines are utilized for patient safety during procedures to reduce the risk of pulmonary aspiration. The American Society of Anesthesiologists (ASA) recommends clear liquids up to 2 hours before non-emergent procedures, although many facilities still implement the outdated practice of ordering NPO after midnight. This practice can lead to prolonged fasting, which may cause increased hunger, thirst, hypotension, nausea, and dizziness, ultimately resulting in patient dissatisfaction and discomfort.

Purpose: To review and assess current ASA NPO guidelines that describe best practice to enhance the patient experience without increasing perioperative risk of pulmonary aspiration.

Methods: A …

Balancing Root-Zone Oxygenation And Rhizosphere Stability: The Impact Of Aeration And Hypoxia On Hydroponic Plant Growth, Christian D. Baker

All Graduate Theses and Dissertations, Fall 2023 to Present

As the global population and food demand continue to increase, growers must look to innovative and sustainable methods for plant cultivation. Hydroponics is a popular method of sustainable plant cultivation where plant roots are suspended over a liquid nutrient solution. Hydroponics uses less water compared to traditional agriculture because there is no evaporation or solution runoff. It also maximizes land use, requires fewer pesticides and herbicides, and enables year-round cultivation in controlled environments. However, indoor hydroponic systems rely on artificial lighting, which has higher energy costs than traditional farming methods. Optimizing growing conditions is therefore critical to ensure long-term economic …

Toward Optimizing Fruit Production In Utah Soils: Apple Salt Tolerance Screening And Tart Cherry Fertility Management, Kaitlin Dabbs

All Graduate Theses and Dissertations, Fall 2023 to Present

Fruit production in Utah can be challenging due to local climate and soil conditions. Tart cherries and apples are major fruit crops in Utah, and improvements to these cropping systems would be beneficial for farmers and local consumers. Two experiments were conducted to evaluate desired improvements for these crops. The first study looked for salt tolerance in ten new apple rootstocks. Salty soils can be found throughout the state limiting the land suitable for apple production. When grown in salty soils apple trees often have reduced growth and production potential. A specialized drip irrigation system was constructed in a greenhouse …

Utilizing The Invasive Fruitwood Pyrus Calleryana As Substrate For Mushroom Cultivation, An Experimental Study In Practical Sustainability, Matthew D. Helton

Masters Theses and Doctoral Dissertations

This study evaluated the feasibility of using woodchips from the invasive Pyrus calleryana (Callery pear) as substrate for mushroom cultivation. Pleurotus ostreatus, Hericium erinaceus, and Ganoderma lucidum were grown on a pear wood substrate and on a conventional oak substrate to compare, yield, sensory attributes, and metabolite production. P. ostreatus showed no significant differences in yield or biological efficiency (p > 0.05), only sweetness (p = 0.022) differed significantly. H. erinaceus yield and efficiency were similar (p > 0.05), with greater second-flush yields in oak controls (p = 0.034) but no sensory differences (p > 0.05). G. lucidum performance was comparable across treatments …

Weathering The Divide: Social Determinants, Neighborhood Context, And Systemic Lupus Erythematosus Among African American Women, Vanessa Cl Morman

Electronic Theses and Dissertations

Background: Systemic lupus erythematosus (SLE) disproportionately affects African American women and contributes to racial health disparities in the United States. Although genetic susceptibility influences disease risk, growing evidence suggests that social determinants of health (SDOH), including neighborhood conditions, structural racism, and socioeconomic disadvantage, contribute to disease development and progression. Epigenetic mechanisms may provide a biological pathway linking adverse social conditions to chronic disease disparities. This dissertation examined the influence of SDOH on SLE disparities through evidence synthesis and empirical investigation to inform public health practice and policy.

Methods: This integrated learning experience consisted of three complementary manuscripts. Aim 1 was …

Leveraging Mammal Mycophagy To Determine Environmental Drivers Of Truffle Diversity, Brittany Hartsock

Electronic Theses and Dissertations

Many mycorrhizal fungi are hypogeous (truffle-forming), producing underground fruiting bodies. Studying truffles is inherently challenging due to their hidden nature. However, mycophagous mammals provide a unique opportunity to study hypogeous fungi because they rely on truffles as a food source. Although several truffle species have recently been described in the southern Appalachian region, their fruiting patterns remain poorly understood. To address this, we quantified truffle richness and spore loads from 670 Peromyscus scat samples collected across 42 sites spanning an environmental gradient during 2024 in the Blue Ridge Mountains of East Tennessee. We found that truffle richness and spore abundance …

Caribou Migration And Non-Local Hunting In Northwest Alaska: A Gis Analysis Of Hunting Activity And Its Relationship With Caribou Migration Corridors, Brittney L. Jiménezszabo

Geography and the Environment: Graduate Student Capstones

Indigenous Alaskans rely on subsistence hunting for food, with Barren-ground caribou making up approximately 27% of their diet. It is believed by subsistence hunters that non-local hunting is forcing a change in caribou migration behavior. This study examined non-local harvesting records from 2013 – 2025 in the northwest and interior Game Management Units (GMU) and Alaksa’s Western Arctic Caribou Herd (WACH) migration range data to answer the question, is there a spatial relationship between non-local harvests and WACH migration behavior. Mixed methods included spatial autocorrelation and local statistics. Findings led to the rejection of the null hypothesis which will help …

The purpose of this study is to analyze the water quality conditions of the region over time, comparing locations around the bay to identify hyperlocal features that influence larger trends in the hydrological system. Ten variables were used as water quality indicators, including total Kjeldahl nitrogen, salinity, pH, Secchi disk depth, and total phosphorus, among others, across five stations in the bay, between 1994 and 2024. After data cleaning and standardization methods were applied, principal component analysis …

Optimizing Nanoparticle Quality And Function In Applied Research, Angela M. Fried

Dissertations, Theses, and Capstone Projects

Radiology tests are among the fastest-growing categories of diagnostic analysis, and the gold standard of radiology tests is MRI.  MRI can be more informative if a contrast agent is used, and the standard of care contrasting agents (CA) are gadolinium-based.  Gadolinium is a heavy metal, toxic, and contraindicated for renal-compromised patients and the critically ill.  We propose a nanogel (NG) vehicle for an alternative organic CA.  CNs like 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPOL) and its derivatives have a variety of medical and industrial uses.  These cyclic CNs are stable, synthetic radicals with distinctive EPR/ESR signals and are helpful for various experimental applications, from …

Quantitative Analysis Of Blue 1 Dye In Commercial Sports Drinks By Uv -Vis Spectroscopy And Hplc-Dad, Mikayla Bush

Forensic Science Master's Projects

Food dyes are natural or synthetic substances added to foods, beverages, and cosmetics to enhance color and visual appeal. Although they provide no nutritional value, they are widely used to attract consumers, particularly children. Concerns have been raised about the potential health effects of synthetic dyes, including links to hyperactivity in children, tumor formation at high doses, and possible impacts on gut and brain function. In response, regulatory efforts are ongoing. In April 2025, the U.S. Department of Health and Human Services (HHS) and the Food and Drug Administration (FDA) announced an initiative to phase out petroleum-based food dyes, including …

The Cranial Nerves And Electrical Stimulation, Devin K. P. Adair

Dissertations, Theses, and Capstone Projects

Cranial nerves provide afferent pathways that enable bottom-up modulation of central autonomic and cognitive neural pathways. Because these pathways project to brainstem nuclei such as the nucleus tractus solitarius and engage neuromodulatory systems, including the locus coeruleus, electrical stimulation offers a mechanistically grounded approach to influencing brain function. This thesis tested whether active transcutaneous auricular vagus nerve stimulation (taVNS) produces physiological responses indicative of parasympathetic engagement, defined as decreases in heart rate, increases in heart rate variability, and decreases in respiration relative to a dose-matched earlobe control condition. Using cardiac and respiratory measures as physiological markers, taVNS at the tragus …

Staff Education To Increase Knowledge And Awareness Of Sexually Transmitted Diseases, Alie Sholola Sahid

Walden Dissertations and Doctoral Studies

Background STIs or sexually transmitted diseases (STDs) are consequential public health emergencies that affect millions of people globally and have long-term health implications (Garcia et al., 2024). STIs are infections that are passed from one person to another through sexual contact with the most common types of STIs include chlamydia, trichomoniasis, general herpes, and human papillomavirus (HPV). It is estimated that each year, more than 20% of the U.S. population has had an STI, with around 26.2 million cases per year (Centers for Disease Control and Prevention [CDC], 2024a). The common types of STIs include chlamydia, trichomoniasis, general herpes, and …

Moralized Indulgence In The Age Of Inflation: How “Better-For-You” Dessert Brands Reframe Pleasure As Self-Care, Dariya Savrukova

Honors College Theses

In the modern U.S. food landscape, the line between indulgence and wellness has nearly disappeared. The booming “better-for-you” dessert industry, owned primarily by multinational giants such as Mondelēz International, PepsiCo, and Mars Inc., reframes high-sugar, high-calorie treats as acts of self-discipline or self-care. This phenomenon is often referred to as “healthwashing” (Tufts Health & Nutrition Letter, 2022), when through verbal and visual language, these companies transform indulgence into moral consumption, inviting consumers to feel virtuous through consumption. Many consumers crave stability and health, but navigate an environment saturated with manipulative design and ambiguous claims. “Better-for-you” branding exploits this gap by …

'In America On Twofold Mission': Elite Filipina Women On The U.S. Stage, 1898-1929, Catherine D. Mayfield

Graduate Masters Theses

After more than 300 years of Spanish colonization of the Philippines, the United States’ acquisition of las Islas Filipinas at the end of the Spanish-American War introduced the Philippine Islands to yet another colonizer. Amidst a backdrop of insurgent resistance and the building of a U.S.-based education and government system under the guise of “benevolent assimilation,” elite Filipina women navigated a mélange of cultural values and the possibility of new public roles. Filipino “elites,” those with political or economic power at the upper echelons of Philippine society, played key collaborative roles for the U.S. colonial regime. Yet the actions and …

Tracking Towards Zero: Implementing A Picc Team Tracker To Prevent Clabsis, Carolina Maria Gerodias Cayetano

Master's Projects and Capstones

Background: Central line-associated bloodstream infections (CLABSIs) remain among the most serious and costly healthcare-associated infections in acute care settings, with each event associated with significant excess mortality, prolonged hospital stays, and avoidable healthcare costs. At Hospital A, a 239-bed acute care facility, two of six total CLABSI events over a 12-month period were associated with peripherally inserted central catheters (PICCs), representing 33% of all facility CLABSIs and exposing a critical gap in standardized PICC line surveillance and maintenance bundle monitoring.

Problem: The PICC team lacked a systematic, real-time tracking mechanism to monitor central line maintenance bundle adherence across seven adult …

Effect Of Vocational Training Programs On The Mental Health Of Indian Women Living In Contexts Of Urban Poverty (Or Urban Slums), Sriramya Potluri

Graduate Doctoral Dissertations

Women living in contexts of urban poverty (IWLCUP) experience disproportionately high rates of psychological distress, yet their mental health needs remain largely underrecognized. Beyond individualized explanations, broader ecological perspectives situate these women’s distress within previously underemphasized macrolevel forces and acknowledge the role of inequity and related structural disparities (e.g., economic, sociocultural, political etc.) in their oppression and disempowerment, thereby contributing to increased psychological vulnerability. Such frameworks call for intervention efforts that reduce individual psychological risk by addressing structural determinants proximally and distally impacting the lives of IWLCUP. Specifically, targeting poverty and economic insecurity might drive positive downstream effects that ultimately …

Governing Climate Change For Sustainable Food Security In The Busoga Region Of Uganda, James Kintu

Graduate Doctoral Dissertations

Busoga, Uganda's most sugarcane-intensive sub-region, hosts seven mills and an expanding outgrower economy, yet remains among Uganda's most food-insecure areas, with over half of its households food-insecure. This study examined how governance of climate change and sugarcane expansion shapes capabilities for food access, land tenure, and decision-making among women, youth, and land-poor households in Jinja and Buyende.

The study developed an integrated CA-CEP-RFS framework, combining the Capability Approach, Comparative Environmental Politics, and the Resilient Food Systems framework, with Sen's Entitlement Framework bridging capabilities to production, trade, own-labor, and transfer entitlements. A qualitative case study drew on a documentary review, 27 …

The Dual Impact Of Professional And Community Interventions On Recidivism, Anjelika M. Dillard

Master of Arts in Human Services

This capstone project evaluates the effectiveness of professional and community interventions in reducing criminal recidivism and facilitating successful community reintegration for justice-involved individuals. Grounded in the Risk-Need-Responsivity (RNR) model, Desistance Theory, and Trauma-Informed Care frameworks, this study synthesizes contemporary behavioral health and criminological literature to examine how institutional programming and post-release community support interact to foster long-term behavioral change. The findings demonstrate that while evidence-based institutional treatments—such as Cognitive-Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and targeted vocational training—provide essential foundations for cognitive restructuring and skill acquisition, institutional programming alone is insufficient to prevent re-offending. Long-term desistance depends on an …
