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 …

An Evaluation Of Staff Training To Teach Implementation Of Functional Analysis Of Inappropriate Mealtime Behavior, Lauren Marie Lightner

Theses and Dissertations

Avoidant/Restrictive Food Intake Disorder (ARFID) along with other feeding disorders are prevalent in both neurotypical children along with children diagnosed with autism spectrum disorder (ASD) and other developmental disabilities. Children with feeding challenges often exhibit inappropriate mealtime behavior (IMB) to avoid consuming non-preferred foods. It is pertinent to determine the function of IMB in order to create an efficacious treatment; one such assessment is the functional analysis (Iwata et al. 1982/1994). Iwata et al. (2000) taught students how to implement a functional analysis of self-injurious behavior using behavioral skills training. Since the assessment’s development, it has been extended to various …

Transcriptomic And Genomic Insights Into Nutrient Stress Responses And Subgenome Evolution In Chenopodium, Ashley Kathleen Marcheschi

Theses and Dissertations

Chenopodium is a diverse genus of nutritionally and ecologically important species in the Amaranthaceae family. This thesis investigates two outstanding questions in the genus: how Chenopodium quinoa responds transcriptionally to nutrient deficiency and how Australian Chenopodium species are related through their subgenomic ancestry and evolutionary history. First, we characterized transcriptomic responses of C. quinoa to deficiencies of twelve essential macro- and micronutrients across leaf and root tissues using RNA sequencing. Leaves showed the strongest responses under nitrogen, potassium, magnesium, and zinc deficiency, while roots responded more evenly across conditions. Recurring responses included suppression of photosynthesis, remodeling of translational machinery, reactive …

Service Providers' Descriptions Of Survivors' Experiences With Mental Health Treatment, Melanie Gonzales Puente

Theses and Dissertations

Human trafficking survivors experience significant mental health challenges and barriers that limit their engagement towards treatment. A qualitative study was conducted that included semi-structured interviews of 33 professionals working with survivors of human trafficking in the United States. Findings indicate that survivors' engagement in treatment is limited by mistrust of providers, stigma, and a lack of access to services. Providers emphasize that addressing basic needs (e.g., safety and housing) must occur before engaging in trauma-focused therapy. Positive outcomes are associated with strong therapeutic relationships, autonomy, trauma-informed, individualized care, and offering comprehensive services. Furthermore, mental health providers should have certain abilities …

A Rho5-Cnc1-Dnm1 Signalling Module Coordinates Multi-Organelle Execution Of Regulated Cell Death In Yeast, Justin Bauer

Theses and Dissertations

Regulated cell death is a conserved process with major implications for health and disease, yet how yeast cells integrate stress signals to determine survival versus death remains unclear. This thesis investigates Cyclin C (Cnc1), a conserved Mediator kinase module component with both transcriptional and mitochondrial roles. Together with Cdk8 Cnc1 primarily represses stress response genes, while upon stress it translocates to the mitochondria to induce mitochondrial fragmentation with the dynamin-related GTPase Dnm1. Using structure-guided separation-of-function mutants, I demonstrate that Cnc1-dependent death requires its mitochondrial function rather than its transcriptional role, and that its effector Dnm1 acts as a signaling node …

Integrative Assessment Of Body Composition And Micronutrient Status In An Adult Egyptian Population, Roua Aref Nouh

Theses and Dissertations

Integrative Assessment of Body Composition and Micronutrient Status in an Adult Egyptian Population: A Functional and Biochemical Approach

Obesity and metabolic dysfunction are increasingly recognized as heterogeneous conditions that cannot be sufficiently characterized by body mass index (BMI) alone. Alterations in body composition, particularly central adiposity and skeletal muscle mass, may coexist with micronutrient imbalances even among individuals who fall outside conventional BMI-based obesity classifications. In clinical settings, such metabolic vulnerability is frequently accompanied by non-specific functional symptoms, highlighting the need for integrative assessment approaches that extend beyond weight-centered metrics. This cross-sectional study aimed to investigate the associations between micronutrient …

Between Reform And Dependency: Ifi Influence On Egyptian Food Sovereignty, Nayera Ayman Abouelfarh

Theses and Dissertations

This thesis examines how international financial institutions (IFIs), particularly the International Monetary Fund (IMF) and the World Bank, have influenced Egyptian food sovereignty between 2016 and 2024. It asks how IFI-backed structural adjustment programs, policy influence, and ideational influence reshaped Egyptian public policy and affected the state’s capacity to autonomously manage its food system. The thesis argues that IFI-driven reform agendas prioritized macroeconomic stabilization, fiscal discipline, and export-oriented growth over food sovereignty, increasing Egypt’s external dependence and vulnerability to global market shocks. Methodologically, the study employs a qualitative comparative case study design combining process tracing and thematic document analysis using …

Beyond Emergency: Charting Pathways To Sustainable Development In Fragile And Conflict-Affected Settings: A Case Study Of Yemen, Sharif Abdurabu Salem Farid Alsahbool

Theses and Dissertations

For nearly a decade, Yemen's eastern governorates of Hadramawt, Shabwah, and Al‑Mahrah have been relatively stable, yet the international aid system has kept delivering short‑term humanitarian relief like food baskets and water trucking instead of shifting to sustainable development that could rebuild people's lives, create jobs, fix infrastructure, and strengthen local government. This thesis investigates why this transition has taken so long. Based on 21 interviews with government officials, international NGO staff, and local NGO managers in these three governorates, the study develops a new way of understanding the problem. It introduces three ideas: the 'emergency mentality', which is a …

Discovery Of Bmi-Associated Gut Microbiome Signatures In The Awi-Gen 2 Cohort, Meriem Yagoubi

Theses and Dissertations

Obesity is increasing across sub-Saharan Africa amid rapid dietary, environmental, and urbanization transitions, yet the gut microbiome features associated with adiposity in African populations remain under-characterized. This study investigated whether species-level gut microbiome composition is associated with body mass index (BMI) in the AWI-Gen 2 cohort, and whether BMI-associated microbial signals remain detectable after accounting for the dominant geographic structure of the microbiome. Gut microbiome community structure and diversity were characterized across 1,665 participants, and differential abundance analysis was used to identify taxa associated with BMI after controlling for study site. Machine learning models were then trained to assess how …

Injectable, In Situ Forming Peptide Nanofiber Reinforced Composite Hydrogels For Age-Related Macular Degeneration, Shambhavi Bagewadi Ms

Theses and Dissertations

Cell therapy for age-related macular degeneration (AMD) is limited by the absence of a functional substrate such as Bruch’s membrane (BM), which is critical for retinal pigment epithelial (RPE) cell survival and integration. Although preformed substrates have been explored, their implantation can disrupt the fragile retinal architecture, compromise ocular immune privilege and increase infection risk. To address these limitations, an injectable hydrogel capable of forming in situ was developed. The hydrogel consists of thiol-modified hyaluronic acid (HA-SH) and polyvinyl alcohol (PVA). Peptide nanofibers were incorporated to enhance structural reinforcement. Three self-assembling peptides - RADA-16, GAGA and GAGA-YIGSR were designed and …

Intersection Of Food Insecurity And Housing Among Veterans And Disabled Adults, Julie Anne Stepp

Theses and Dissertations

This study examines how housing tenure is associated with food insecurity (FI) among veterans and adults with disabilities, utilizing the housing-food insecurity nexus framework. Previous research documents elevated FI among veterans and individuals with disabilities, yet few studies assess housing tenure as a mechanism connecting these statuses to food hardship. Using data from the 2024 National Health Interview Survey Adult Sample (n=32,629), logistic regression models estimate the independent and interactive effects of renting, veteran status, and disability status on FI. Results suggest renters have significantly higher odds of FI than homeowners, even after adjusting for poverty status, SNAP participation, and …
