Multi-Factor Mathematical Optimization For Healthcare Referral And Facility Placement, Mitchell Moody

Theses

This thesis addresses the challenge of optimizing patient referrals in healthcare systems by integrating clinical needs, geographic proximity, and dynamic infection risk. Healthcare referral networks (HRNs), which capture patient transfers between hospitals, serve as the foundation of the study. First, a recommendation algorithm is developed to assign patients by jointly considering clinical compatibility and logistical considerations like travel distance, striking a balance between quality and accessibility. Building on this, a reinforcement learning framework is proposed to dynamically adjust referral strategies for vulnerable patients by incorporating the evolving risk of hospital-acquired infections. Finally, long-term planning is explored through methods that recommend …

Generation Of True Random Numbers With Actively Stabilized, Low Dimensional Chaos, Aidan Barton

Theses

True Random Number Generators (TRNGs) are heavily used and their design often relies on empirical validation from statistical test suites. Reliance solely on empirical observations to estimate entropy rates for cryptographic applications introduces risk, as accurately inferring long-term correlations demands prohibitively large datasets. Empirical validation of TRNGs must be supplemented by strong theoretical backing to justify estimated information theoretic quantities. We present an electronic, hardware TRNG scheme that produces a maximally random output guaranteed from first principles. This TRNG uses a pulse-width based hardware realization of an iterated map that produces physical entropy via low-dimensional chaotic dynamics. The simple dynamics …

Theatre As Sanctuary: Queer Identity, Religious Trauma, And The Path To Healing, Casey Worley

Theses and Dissertations

Growing up as a queer individual in a deeply religious Southern Baptist community, I learned early that faith and identity could feel like irreconcilable forces. I sat in the pews, surrounded by voices that preached love but often excluded people like me. For years, I struggled with the question: Can I be both queer and faithful? This tension—between belief and belonging, between the church I was raised in and the identity I could no longer deny—became the foundation of my journey, my artistic practice, and this thesis.

Through this research, I explore the intersections of queer identity, religious trauma, and …

Vessels Of Spirituality: Merging Faith And Form, Maryam Al-Tajer

Theses and Dissertations

According to traditional Islamic teachings, natural materials like frankincense, black sesame seeds, and sidr (jujube) leaves are valuable both physically and spiritually. Historically, they have been used for healing and purification. Nowadays, influenced by contemporary science, people tend to overlook their metaphysical value, focusing on their medicinal uses. Similarly, Muslims assign spiritual qualities to the Muqatta’at, the disconnected letters that preface several surahs of the Holy Quran, believing them to contain sacred power. In both of these cases, the material leads to the spiritual.

Through material experimentation, informed by religious texts, my thesis combines revered materials with sacred letter forms …

The Trauma-To-Prison Pipeline: A Multi-Level Theoretical Framework Exploring The Intersection Of Inequality, Trauma, And Exclusionary Discipline, Dana Ainsworth

Theses and Dissertations

The school-to-prison pipeline (STPP) is a widely recognized and extensively studied metaphor used to describe the process by which school discipline policies increase the risk of juvenile justice system involvement, particularly among historically marginalized populations. While it has been instrumental in shaping educational policy, the STPP framework has not evolved to account for the critical impact of trauma on learning and behavioral outcomes. Furthermore, it overlooks the role of systemic inequality that increases trauma exposure and produces concentric patterns of marginalization.

Drawing on research across the fields of education, public health, sociology, and criminal justice, this study proposes a theoretical …
