Enhancing Hospital Length Of Stay Using Ai Agent Modular Capabilities, Dami Fred

Theses and Dissertations

Hospital Length of Stay (LOS) analysis is essential for managing hospital efficiency and financial performance, yet the analytical depth required remains inaccessible to many organizations due to technical and resource constraints. This thesis introduces the AI Agent Modular Capabilities (AIAM) framework, which decomposes LOS analysis into discrete, codifiable capabilities integrated into a single skill activatable with one prompt. Seven AI Agent Modular Capabilities were developed using a Work Breakdown Structure and tested against a simulated hospital scenario across three successive skill versions. Results demonstrate that the packaged AIAM skill produces comprehensive, consistent, multi-section LOS analyses from a single interaction, outperforming …

Abject And Uncanny Manifestations Of Sexuality And Sexual Desire In Nineteenth-Century Gothic Literature, Varvara Kuznetsova

Theses and Dissertations

This thesis explores the ways in which psychoanalytic concepts of the abjection and the uncanny were used to depict monsters and monstrous bodies in nineteenth-century Gothic literature as a site of social, cultural, and sexual transgression. Through the intersections of queer theory, monster theory, and psychoanalytic theory, I examine and analyze depictions of women as monstrous figures in Samuel Taylor Coleridge’s Christabel (1816), Mary Shelley’s Frankenstein; or, The Modern Prometheus (1818), and Sheridan Joseph Le Fanu’s Carmilla (1872). In particular, I aim to detail how language and descriptions of women monsters become coded elements that reveal monstrosity and transgression.

Integration Of Ders Volt-Var Dynamic Constraint Into Time-Coupled Optimal Power Flow For System Stability, Shadrack T. Asiedu

Electronic Theses and Dissertations

The transition toward power systems with higher levels of inverter-based generation requires operating models that account for the dynamic support available from distribution-connected resources. Although inverter-based DERs can provide fast reactive-power support through functions such as Volt–VAR control, conventional optimal power flow models generally represent these resources as static power injections. In addition, transmission-level dispatch commonly represents the downstream distribution system as an aggregated load and does not explicitly consider the voltage at the point of common coupling. Consequently, an OPF solution may satisfy the transmission-bus voltage constraints while producing an operating point at which the downstream DERs do not …

Fostering A Growth Mindset In Mathematics: Faculty And Student Experiences, Yolanda G. Rush

Theses and Dissertations

According to the Center for Community College Student Engagement (2019), many students attending two-year institutions need productive persistence strategies, including the development of a growth mindset. Although some growth mindset interventions have been effective in improving academic achievement among students (Boaler, 2016; Canning et al., 2024) and persistence (Lewis, 2019) among students, especially those with developmental needs (Suh et al., 2019) and those in mathematics, little is known about the experiences of students and teachers (i.e., students’ perceptions of teachers’ intentions and implementation) as teachers work to foster a growth mindset culture (Murphy et al., 2021). In this dissertation, I …

The Role Of Non-Academic Staff In First-Year Retention At Regional, Comprehensive Universities, Marco A. Krcatovich Ii

Theses and Dissertations

Regional comprehensive universities (RCUs) serve a large share of U.S. undergraduates, yet the role of non‑academic staff in shaping first‑year retention remains understudied. This dissertation examines how staff diversity and staffing structures relate to student persistence using seven years of IPEDS panel data and Linear Mixed‑Effects Models. Analyses were conducted separately for residential and commuter RCUs to reflect their distinct engagement environments. Findings show that staff diversity is significantly associated with retention, though the direction and magnitude vary by campus type and staff role. Staffing structure also matters as higher proportions of full‑time staff are positively associated with retention at …

International students represented an important sector of the United States higher education and labor force ecosystem, contributing significantly to academic innovation, institutional diversity, and economic growth. Illinois, which is a major educational and industrial hub, attracted thousands of international students annually and played a critical role in the development of global talent essential to both the state and the national economy. Despite these contributions, international students faced persistent challenges when navigating career advancement in the United States. Recent immigration policy shifts intensified national security concerns and employer reluctance to sponsor visas, reframing international students from valued contributors to perceived labor …

Understanding Faculty Perceptions Of Shared Governance At A Four-Year Public University: A Case Study Of The University Of Ghana, Patrick Amponsah

Theses and Dissertations

The purpose of this qualitative single-case study was to explore how faculty at the University of Ghana perceive and experience shared governance, how it is practiced institutionally, and what outcomes they associate with it. Although shared governance is widely promoted as a democratic and collegial model of decision-making in higher education, its implementation remains underexamined. The study interviewed twelve (12) full-time faculty members who worked at the University of Ghana. Thematic analysis revealed ten interrelated themes, including structured participation with limited influence, shared governance as an opportunity for faculty input, and the presence of both collaborative attitudes and formal committee …

Staff Attitudes Toward Ai Adoption At A Private Research University, Ashley C. Smith

Theses and Dissertations

This study addresses the limited research on university staff attitudes toward artificial intelligence use and adoption. Using the Unified Theory of Acceptance and Use of Technology (UTAUT) research framework, the General Attitudes towards Artificial Intelligence Scale (GAAIS), and quantitative survey methodology, the study examines the attitudes of higher education staff toward AI, specifically examining whether demographic or professional characteristics are factors. The findings indicate that staff had moderately negative attitudes toward AI while also expressing some concerns. The results suggest that more resources and support for AI are needed for staff to address concerns. It also suggests that construct-level analysis …

First- And Second-Generation Immigrant Emerging Adults’ Career Aspirations, Laura A. Botros

Theses and Dissertations

Despite first- and second-generation immigrants making up 19.6% of the U.S. workforce (U.S. Bureau of Labor Statistics, 2024), research exploring their career aspirations is scarce. Studies show that individuals’ cultural backgrounds significantly shape first- and second-generation immigrants' career aspirations, values, and professional goals (Kao, 2004; Polenova et al., 2017). The purpose of the study is to examine how first- and second-generation immigrant emerging adults' cultural backgrounds inform their career aspirations. I utilized a qualitative approach by asking participants about their cultural background, career aspirations, and what influenced their career aspirations. Interviews and a cognitive map activity were conducted to investigate …

Data Utilization In Facilities’ Performance Management Decision- Making At U.S. Four-Year Public Institutions: A Cross-Sectional Exploratory Study, Tanaporn Supanichrattana

Theses and Dissertations

The growing complexity of higher education finance, aging infrastructure, and rising accountability expectations has intensified demands on facilities organizations to manage institutional assets strategically. As colleges and universities face sustained fiscal constraints and expanding operational pressures, the ability of facilities leaders to use data to inform performance management has become increasingly critical. Despite this importance, limited empirical research has examined how facilities leaders integrate data into decision-making within public higher education contexts.

The quantitative study employed a cross-sectional, exploratory survey design to investigate data utilization practices among facilities leaders at U.S. public four-year institutions. Guided by the Data–Information–Knowledge–Wisdom hierarchy and …

Customers' Perceptions Of Customer Service After The Covid-19 Pandemic, Marissa Young

Theses and Dissertations

This thesis examines how customers perceive customer service after the COVID-19 pandemic, using qualitative data from an open-ended survey to evaluate how expectations, experiences, and the meaning of service have shifted. The findings demonstrate that consumers view customer service as a holistic process influenced by interpersonal communication, operational efficiency, product availability, and pricing transparency. Participants emphasized both positive and negative encounters, stating that the COVID pandemic fostered lowered expectations due to staffing shortages and work stress, while also remaining observant of service inconsistencies. These results relate to theories of service quality, emotional labor, and organization-public relationships by illustrating how crisis …

We Can Fix It: How Right To Repair Policy Is Enacted In Different States, Zachary Ryan Johnson

Theses and Dissertations

This thesis explores early signs of policy diffusion within right to repair legislation across 10 states. Data points from each bill includes the devices protected, exempted, vote share of Republican legislators, parts pairing bans, and other provisions of bills. Bills that pass have unique aspects that show signs of policy learning from successive states. This thesis seeks to establish a framework for future research to explore policy diffusion in a new area of consumer protection.

Theoretical Analysis Of Filtering And Smoothing Techniques In Stochastic Time Series, Kaosarat Bola Azeez

Theses and Dissertations

Polynomial-preserving linear filters are fundamental tools for smoothing and trend extraction in noisy time series, particularly when the objective is to reduce short-run variation without distorting underlying low-degree structure. This thesis develops a general framework for such filters based on local polynomial approximation and least-squares estimation. In particular, we establish that the resulting estimators can be represented as symmetric linear filters whose weights satisfy moment conditions that ensure exact polynomial reproduction up to a specified degree. Building on this framework, we derive explicit coefficient vectors for several classical smoothing filters, including the Savitzky-Golay filters SG(5,2) and SG(7,3), as well as …

Schiff Bases As Versatile Platforms: From Multinuclear Dysprosium Complexes To Halogen-Mediated Quasiracemic Crystal Engineering, Macy M. Michorczyk

Theses and Dissertations

Understanding the factors that govern molecular assembly is fundamental in both coordination chemistry and crystal engineering. This thesis investigates these processes through two studies that employ single-crystal X-ray diffraction to elucidate the structural principles underlying the formation of multinuclear metal complexes and the crystal packing of quasiracemates.

The first study examines the unexpected formation of multinuclear metal complexes. Structural characterization of a series of dysprosium complexes was used to compare molecular architectures and identify structural relationships that support a proposed pathway of formation. These findings shed insight into the assembly process that may have lead to their formation.

The second …

From Rocks To Rockets: How Mineral Wealth Fuels The Arms Trade, Samuel G. Majka

Theses and Dissertations

This study addresses a critical gap in the resource curse literature by examining how strategic mineral wealth, central to the global clean energy transition, influences international arms transfers. While the relationship between oil rents, militarization, and conflict is well-established, the role of non-hydrocarbon resources and conflict-related variables remains underexplored. This paper posits that mineral rents provide governments with unearned, discretionary income, relaxing fiscal constraints and creating powerful incentives for both resource-rich states and major power suppliers to increase arms flows to secure political control, suppress internal dissent, and maintain access to valuable deposits. Using a country-year panel dataset spanning 1990-2023 …

During growth, data was collected three times for each cultivar including plant length, internode length, number of nodes, number of leaves per stem, SPAD (Soil Plant …

Reconceptualizing Instructional Supervision For Stem Education In The Digital Age, Armen Alvarez

Theses and Dissertations

This conceptual thesis reconceptualizes instructional supervision for AI-enabled STEM teaching in the Digital Age. Traditional supervision models, including clinical, developmental, and cognitive coaching, emphasize human-centered observation and feedback but lack guidance for supervising AI-mediated instruction, interpreting algorithmic outputs, and addressing neurodiverse learner variability. Using integrative literature review methodology, this thesis synthesizes scholarship across five theoretical foundations: epistemic perspectives, the neurodiversity paradigm, Universal Design for Learning, human-centered AI and educational leadership, and supervision literature.

The resulting conceptual framework organizes supervisory attention into four interconnected domains:

• human-centered AI use in teaching and assessment,
• neurodiversity- and UDL-informed pedagogy,
• relational and compassionate classroom climate, …

Effects Of Interpersonal Emotion Regulation Strategies On Job Attitudes And Well-Being, Kara Cannon

Theses and Dissertations

Interpersonal emotion regulation involves using social interactions to influence their own or another’s emotions (Gross, 1998). Although previous research has examined the relationships between intrapersonal emotion regulation and workplace outcomes, there is a lack of research on interpersonal emotion regulation in the workplace context. The current study extends this research by examining the relationships between interpersonal emotion regulation strategies, co-rumination, well-being, and job satisfaction, and examines which interpersonal emotion regulation strategies are better predictors of the outcome variables than others. Positive correlations between interpersonal emotion regulation strategies and well-being and between co-rumination and well-being were found. Perspective taking and enhancing …

Exploring The Role Of Racial Microaggressions And Campus Climate In Fostering Sense Of Belonging For Black Latiné College Students, Lourdes D. Concepción Cabán

Theses and Dissertations

Racial microaggressions are subtle verbal or nonverbal behaviors that convey hostility and exclusion toward People of Color (Sue et al., 2007). These acts negatively impact the well-being, perceptions of inclusivity, and sense of belonging of marginalized groups in higher education (Solórzano & Pérez Huber, 2020). Black Latiné college students face unique challenges at the intersection of anti-Blackness and racialized Latinidad, compounding the effects of racial microaggressions in historically white institutions (Torres et al., 2012). I conducted a study with 77 Black Latiné undergraduate students from Midwestern universities to examine the relation between racial microaggressions, perceptions of campus climate, and sense …

Tensions And Possibilities: A Study Of International Graduate Students' Encounters With Critical Pedagogy In The United States, Munchuree Kaosayapandhu

Theses and Dissertations

This study investigates the question, “How do international graduate students experience and negotiate their encounters with critical pedagogy across time and educational contexts?” The research was motivated by the researcher’s own experience in encountering critical pedagogy and prior studies focusing on critical pedagogy from the teacher perspective. This left a gap in understanding the student experience. The research used the phenomenology paradigm. The participants included six international graduate students in education studies programs. Using the phenomenological interview approach, each participant was asked over a series of three interviews about past experiences of education, their initial encounters with critical pedagogy and …

Theses and Dissertations

The purpose of this research is to ascertain whether or not the skill level of crafters can be assessed by the errors visible on the Hopewell cores used to make stone blades. This assessment was carried out using four points of focus; core shape, blade length, stepping mistakes and termination errors. This assessment was carried out on twenty-nine cores from the Crane site and nineteen cores from Mound house. Total error rates were used to assign cores to three different skill levels, experienced, intermediate, and novice. The assessment of these blade cores illustrates that skill can be observed, and that …

Learning Sustainability Under Tension: Experiential Learning And Reflexive Sensemaking In A Place-Based Simulation, Moon Kyung Cho, Nereu F. Kock, Nargis Sultana

Business Faculty Publications

This study examines how sustainability judgment develops in place-based experiential learning as learners navigate tensions between financial performance and environmental responsibility. Using a team-based, technology-enabled business simulation situated in a place-based context, participants managed a simulated company over eight quarters and subsequently reconsidered their decisions from the perspective of external auditors. The findings show that sustainability judgment developed iteratively through experience, reflection, and sensemaking. Participants distinguished sustainability practices according to their strategic and integrative potential and increasingly recognized that sustainability investments could support operational efficiency, innovation, and long-term financial viability rather than necessarily conflict with financial objectives. Place directed attention …

A Framework For Reliable Domain Ai: Knowledge-Grounded Data And Logic-Graph Reasoning, Yangxiao Bai

Electronic Theses and Dissertations

Large language models (LLMs) perform well on general tasks, yet their deployment in specialized, high-stakes domains such as public health remains unreliable. Models hallucinate facts, combine multi-step evidence incorrectly, and retrieve context that corrupts downstream reasoning. Three root causes underlie these failures: training data that underrepresents rare but critical domain themes, reasoning that is opaque and unverifiable, and evidence use that cannot be re-checked when the evidence changes. This dissertation addresses all three. First, we introduce HDBSCAN_SSA, a coarse-to-fine topic-modeling pipeline that couples density-based clustering with a novel Semantic Seed Aggregation algorithm. Using samples drawn from a larger corpus of …

School of Podiatric Medicine Publications

Background: Zirconia is an emerging alternative to titanium for dental implant systems. However, zirconia surfaces can deteriorate under aqueous conditions, thereby compromising mechanical performance. The goal of this study was to assess the impact of biological exposure or aging simulating the oral cavity on the surface integrity and mechanical strength of surface-treated zirconia.

Methods: Partially yttria- or magnesia-stabilized zirconia specimens were polished, acid-etched, or sandblasted. Zirconia disks were exposed to mammalian cells or bacteria. Surface degradation via tetragonal-to-monoclinic phase transformation was assessed by Raman microscopy. Zirconia bars were subjected to accelerated aging by exposure to autoclave steam. Surface morphology was …

Finite Mixture Modeling Towards Applications In Material Science And Biomedical Data, Jason Hasse

Electronic Theses and Dissertations

This dissertation contains three chapters on different applications of mixture regression models, broadly in materials science and public health. We begin with a basic application of finite mixture models and regression mixture models. The materials science analysis was performed entirely using data from finite element simulations of the additive manufacturing process via powder bed fusion. Visualization of the clustering solution as applied to the additive manufacturing designs highlighted the intuitive patterns that could be found. These patterns simultaneously yield the regression coefficients and subgroups of the geometric regions, providing a way to predict stresses and strains in a new geometry …

The Law And Economics Of Resilience, Doni Bloomfield, Jeff Gordon

Faculty Scholarship

The field of law and economics has long studied externalities, the costs and benefits actors create and yet fail to internalize. But scholars have largely overlooked a set of externalities that lead firms across the economy to systematically underinvest in resilience, with macroeconomically harmful consequences. In this Article, we address this gap with a theory of the law and economics of resilience, by which we mean the ability of markets to reliably and optimally meet demand for goods and services without extreme price fluctuations. 

We argue that corporate resilience is determined by a conflict between two basic forces: the resilience …

If I Only Had The Words (To Tell You): Billy Joel Lyrics In Legal And Medical Scholarship, Seuli Bose Brill, Christian H. Brill

Touro Law Review

Law and medicine are often considered to be among the least accessible professions, partly because of the heavy use of non colloquial jargon. This article examines more than 150 instances in which Billy Joel’s lyrics have been used to improve the accessibility of legal and medical scholarship. Legal and medical professionals have used the words of the “Piano Man” to discuss a variety of topics—everything from civil procedure to property rights and the COVID-19 pandemic to colorectal surgery. Nontraditional communications techniques of this type do not just contribute to the body of legal and medical scholarship; they also help professionals …

Unprecedented Leadership For Unprecedented Times: The Ethical Imperative For Transformational Change In American Higher Education, Andrés Acebo

Touro Law Review

Many eras quietly yield to another while its institutions continue speaking the language of a world that no longer exists. Such moments expose the widening distance between inherited assumptions and emerging realities, between institutional memory and societal need, between what once served the public well and what the future now requires. American higher education has arrived at such a moment. For more than a decade, its challenges have been described through the language of crisis. The prevailing literature has documented enrollment decline, demographic transformation, fiscal instability, technological disruption, political polarization, declining public confidence, and institutional fragility with increasing sophistication. Yet …

Combined Effect Of Porosity And Pore-Size Heterogeneity On Young’S Modulus Of Chemically Corroded Rocks, Hao Li, Zhenjiang You, Leo Pel, David Smeulders

Research outputs 2022 to 2026

Young’s modulus is a critical parameter for evaluating the stability of rock reservoirs, such as CO₂ geological storage. These reservoirs are exposed to chemically corrosions, which alter the pore structure, particularly porosity and pore size heterogeneity, thereby affecting Young’s modulus. This study conducted multiscale experiments to investigate how acid-driven chemical corrosion affects pore structure and its relationship with the Young’s modulus of rocks. Nuclear Magnetic Resonance (NMR) was used to characterize pore structure evolution, while corrosion mechanisms were examined via mass loss, XRD, pH monitoring, and ion chromatography. Based on the experimental results, a Kinetic Weibull Modulus (KWM) model was …
