Hepatocyte Peroxisome Biogenesis And Phytol-Induced Metabolic Stress In Liver Disease, William Galloway

Theses, Dissertations and Capstones

Hepatocyte peroxisomes are required for metabolism of phytol-derived branched-chain fatty acids through the ACOX2-SCPx beta-oxidation pathway. This study tests whether hepatocyte-specific deletion of PEX16 (Pex16^Alb-Cre), which eliminates peroxisome biogenesis, sensitizes the liver to phytol-induced injury. The Pex16^Alb-Cre mice and their normal control Pex16^fl/fl mice were fed the Lieber-DeCarli liquid with or without 0.1 percent phytol for eight weeks. Serum alanine aminotransferase (ALT) and liver index were measured. Liver sections were stained with hematoxylin and eosin and Masson’s trichrome. Immunoblot analysis of peroxisomal enzyme expression was also performed. Phytol had no effect in Pex16^fl/fl mice as …

Anaerobic Digestion Of Variable, Heterogeneous Organic Wastes Under Changing Operational Conditions And Bioaugmentation: Impacts On Process Performance And Microbiome Dynamics, Victoria Holliday

Substrate-specific enrichment cultures were developed for bioaugmentation and implemented in select phases to assess its impact. Both reactors exhibited similar performance, transitioning through periods of stability, stress, and recovery in response to operational changes. Corresponding shifts in dominant taxa …

Comparing Strength Testing Measures And The Association Of Strength And Body Composition In Young Children, Abigayle R. Spong

Theses and Dissertations--Kinesiology and Health Promotion

Muscle strength is an important component of physical fitness; however, measuring it with isokinetic dynamometry (IKD) is expensive and requires dedicated space. Handheld dynamometry (HHD) provides a practical alternative for field and clinical settings. Thus, the purpose of this study was to compare peak knee flexion and extension torque measured by IKD and HHD in 37 children (ages 5-11 years) and examine relationships with body composition. Participants completed a RAMPing protocol at 90^o knee flexion consisting of two warm-up contractions at 50% and 75% effort followed by three maximal voluntary isometric contractions. Body composition was assessed via DXA scans. …

Fiscal Decentralization, Foreign Capital, And Economic Development In Sub-Saharan Africa, Kwadwo D. Frempong

Theses and Dissertations--Public Policy and Administration

Economic development in Sub-Saharan Africa has been shaped by two transformative policy shifts: widespread fiscal decentralization reforms transferring revenue and expenditure authority to subnational governments, and the pursuit of foreign direct investment to supplement domestic capital. Despite the breadth of these reforms, their effectiveness in promoting sustainable economic development remains empirically contested. This dissertation examines three interconnected questions about fiscal governance and capital flows in Sub-Saharan Africa: what determines the extent to which governments decentralize fiscal authority; how county fiscal composition and revenue autonomy shape subnational economic performance; and how foreign direct investment interacts with domestic investment and growth.

Results suggest that all three modalities can be made to be about equally as effective. We also discuss the efficacy of a fully online asynchronous section of Calculus-Based Introductory Mechanics held in Fall 2025. The …

Equitable Siting Of Green Stormwater Infrastructure In Urban Areas For Flood Resilience In Vulnerable Communities, Elnaz Chitsazzadeh

Planning Dissertations

Cities face increasing pressure from rapid urbanization, aging gray infrastructure, intensifying rainfall, and uneven flood protection. In this context, green stormwater infrastructure (GSI) and other nature-based solutions are increasingly promoted as tools for climate adaptation, flood resilience, and environmental justice. Yet a central planning challenge remains: how to identify where GSI should be prioritized when flood-related physical burden, weak environmental protection, social vulnerability, and lower recovery capacity overlap. This dissertation addresses that challenge in Fort Worth, Texas, by examining how equitable GSI siting can support flood resilience in vulnerable urban neighborhoods.

Framed by urban resilience and environmental justice, the study …

Sexually Dimorphic Effects Of Gpnmb Modulation On Vertebral Bone Mass Regulation And Intravertebral Disc Health, Hakem Altawil, Fayez Safadi

Williams Honors College, Honors Research Projects

Osteoporosis and vertebral degeneration are major contributors to musculoskeletal morbidity, yet the molecular mechanisms regulating vertebral bone and intervertebral disc (IVD) homeostasis remain incompletely understood. GPNMB (osteoactivin) has been identified as a regulator of bone remodeling, though its role in spine health is unclear. This study evaluated the effects of GPNMB deficiency on lumbar vertebral bone microarchitecture and IVD integrity in a sex-dependent context.

Six-month-old male and female wild-type (WT) and GPNMB knockout (KO) mice were analyzed using micro–computed tomography (µCT) of lumbar vertebrae (L4–L6) and histological assessment of the L5–L6 IVD. KO males exhibited increased bone volume fraction, bone …

Conch Gone? Examining Cultural Preservation Through Bahamian Menu Analysis, Adiah J. Saunders

Undergraduate Honors Theses

Social identity theory and acculturation theory expose how cultural practices, such as cuisine, can adapt due to external pressures. In The Bahamas, external pressure from the tourism industry shapes many aspects of public life, by analyzing menus we can see how cultural identity resists or succumbs to change. This study examined how Bahamian cuisine is represented on restaurant menus in Nassau, New Providence amid a dominating tourism industry. Using a stratified random sample of 30 restaurants, 1,155 menu items were coded for cultural origin, cultural language use, promotional features, as well as pricing.

Covering The Care: The Fourth Trimester, Susy Hawes

All Materials

The weeks following the birth of a baby are often described as a time of extremes: profound joy paired with deep exhaustion, vulnerability, and adjustment. For birthing people, this period involves physical recovery from childbirth, dramatic hormonal shifts, disrupted sleep, learning to feed and care for an infant, and navigating major emotional changes. While some new parents have strong support systems, others face isolation, housing instability, or unsafe home environments. This critical 12-week period after birth is now widely known as the “fourth trimester.” Although the language is new, the reality is not. Across cultures and history, the postpartum period …

Leaders sustain organizational resilience by anchoring …

More Than “Just A Misdemeanor”: Why Diversion Is Critical For Low Level Youth Offenders, Lynn Williams, Ariana M. Ellis

Akron Law Student Publications

Over the past two decades, juvenile arrests have declined sharply nationwide. Yet, during this same period, policies and penalties governing youth have grown increasingly punitive. Many lawmakers continue to advance “tough on crime” legislation that subjects all youth in the juvenile justice system to the same level of sanction, regardless of the seriousness of their offense or prior legal history. This article argues that juvenile delinquency should be addressed through individualized assessments of both risk and needs, rather than through uniform punitive measures. Unnecessary or disproportionate court involvement, particularly for low-risk youth, can produce significant short- and long-term harms, disrupt …

Navigating Yellow Zone Sexual Misconduct Cases: Exploring Title Ix Administrators’ Discretion, Angela E. Hobbs

Educational Leadership & Policy Studies Dissertations

This study examines how Title IX administrators exercise discretion when responding to ambiguous sexual misconduct reports referred to as yellow zone. The 2020 Title IX Rules and Regulations introduced a more restrictive definition of sexual misconduct, requiring behavior to be severe, pervasive, and objectively offensive (SPOO) to meet the threshold for formal institutional response. Despite the practical challenges these cases present for institutions, there is limited scholarly understanding of how Title IX administrators make decisions when responding to them. Guided by street-level bureaucracy theory (Lipsky, 1969, 1980, 2010), the study explored how institutional actors exercise discretion in response to regulatory …
