Time Series Decomposition And Forecasting Of Alzheimer’S Disease Mortality Using A Kolmogorov-Zurbenko Filter, Jack D. Farrell

Electronic Theses & Dissertations (2024 - present)

Alzheimer’s disease mortality has substantially risen in recent history, placing a significant burden on public health infrastructure and highlighting the need for improved analytical methods to better understand mortality data patterns and offer reliable predictions. Time series methods often struggle to balance both accuracy and interpretability, which hinders the ability to gather meaningful insights from time series data. To address these limitations, this study applies the Kolmogorov-Zurbenko (KZ) filter to monthly U.S. Alzheimer’s mortality data spanning from 1999 to 2023 and decomposes the series into long-term trend, seasonal, and noise components on a logarithmic scale. Long-term trend accounts for 86.49% …

Punishment, Fast And Slow: Five Experiments On Behavioral Economics In The Mass Incarceration Context, Nathaniel M. Schutten

Electronic Theses & Dissertations (2024 - present)

As many jurisdictions across the United States seek to reduce their prison populations, a pressing question is whether the public will support the reforms necessary to do so. Public openness to reform likely varies across policy areas, with the path of least public resistance occurring where attitudes are the most malleable and loosely held. A major challenge, however, is that traditional methods for measuring public opinion are poorly suited to identifying which policy areas are characterized by such weakly held views.

This dissertation develops a novel behavioral economics framework for identifying these areas. I theorize that when public opinion is …

Family Routines And Cognitive Emotion Regulation: The Role Of Harsh Parenting And Family Activities, Vidhi Jain

Electronic Theses & Dissertations (2024 - present)

Cognitive emotion regulation (CER), consisting of adaptive and maladaptive strategies, is a critical developmental process linked to various well-being outcomes across the lifespan. Family contexts such as daily routines, parenting, and engagement shape the development of emotion regulation. Existing literature generally links family routines to better CER outcomes (Selman & Dilworth-Bart, 2023), but has not yet investigated the impact of routines in adverse family environments. The present study examined whether harsh parenting and the frequency of shared family activities jointly moderate the relationship between family routines and adaptive and maladaptive CER. A sample of emerging adults (N = 210; …

Models Of Emulation: Representations Of Foreign, Indigenous, And Accented Speech In Early American Literature, Elaina A. Frulla

Electronic Theses & Dissertations (2024 - present)

“Models of Emulation: Representations of Foreign, Indigenous, and Accented Speech in Early American Literature” explores how American writers used depictions of “nonstandard” English and accented English language speech, traditionally described as “literary dialect,” as a way to negotiate identity, power, and political belonging in the formative years of nation building after the American Revolution. Beginning with Noah Webster’s mission to establish a standardized pronunciation of the English language that would simplify and purify spoken American-English and definitively differentiate it from what he saw as the corrupted, cosmopolitan British-English model, each of the three chapters examines literary representations of nonstandard emulated …

Neural Network Transceiver For Ltv Mimo Channels, Iresha Amarasekara

Electronic Theses & Dissertations (2024 - present)

Eigenfunctions are commonly employed to characterize kernels in various data-driven analyses. In machine learning, eigenfunction decomposition typically relies on Mercer's theorem, which assumes kernel symmetry. However, this condition is often unmet in communication systems, where channel kernels are asymmetric due to differences in downlink and uplink propagation environments. The High-Order Generalized Mercer's Theorem (HOGMT) provides a systematic approach for decomposing multidimensional asymmetric kernels into eigenfunctions. To address the complexity of eigen-decomposition, this work introduces a baseline neural network (NN) framework HNET. The HNET framework is further enhanced by incorporating the augmented Lagrangian method (ALM) to explicitly enforce orthogonality constraints. This …

Negotiating Quality: A Critical Discourse Analysis Of American Higher Education Policy, John A. Foisy

Electronic Theses & Dissertations (2024 - present)

This qualitative study examined how institutional quality is constructed, communicated, and negotiated through the accreditation process in U.S. higher education. Drawing on a multiple case study design, the research analyzed accreditation-related documents from eight institutions undergoing reaffirmation, including self-study reports, peer review team reports, Commission action letters, and institutional responses. The study was guided by three research questions: (a) What institutional signals of quality are evidenced in self-studies? (b) In what ways does the accreditation process represent a negotiation between accreditors and institutions? (c) What implied views of institutional quality emerge from accreditation discourse?

The study employed a multilayered analytical …

The Instruments Of Chinese Economic Statecraft, Wilson Han

Electronic Theses & Dissertations (2024 - present)

The global economic order is undergoing a profound transformation as China increasingly leverages its vast commercial resources not merely for market expansion, but as strategic instruments to reshape global governance and secure its national interests. Moving beyond traditional analyses that rely on aggregate macroeconomic indicators, this dissertation investigates the targeted, highly asymmetrical mechanisms of Beijing’s economic statecraft. It systematically examines three specific instruments – institutional, financial, and trade – through which China projects structural power and constructs an alternative economic order.

The first empirical study explores China’s institutional statecraft by analyzing its bid to join the Comprehensive and Progressive Agreement …

Stem Cell-Derived Developmental Models For Translational Evaluation Of Disease And Therapy, Maria B. Paredes-Espinosa

Electronic Theses & Dissertations (2024 - present)

Human development as well as congenital and adult diseases emerge from coordinated interactions among multiple cell types, regulatory programs, and tissue compartments that remain largely unresolved. Conventional simple lineage-restricted in vitro systems poorly capture this complexity. My dissertation uses human stem cell-derived developmental models to study human cardiac morphogenesis and heart diseases and application of a networked neuron platform to explore senescence-associated neurodegeneration impact on Alzheimer’s neurons.

Elongating multi-lineage organized cardiac (EMLOC) gastruloids are a synthetic embryology model that co-generates contractile cardiomyocyte populations alongside mesenchymal, endothelial, epicardial-like, neural crest-associated, and neuronal cells within a shared in vitro developmental environment. Single-cell …

New Game Start: Playing With Power, Community And Change In Video Gaming Culture, Jonathan D. Muller

Electronic Theses & Dissertations (2024 - present)

Video gaming culture has long been a site associated with norms and values of whiteness, masculinity, and neoliberalism, with games, players, and developers all reinforcing these. Recently though, gaming culture has been directly involved with social movements and forms of resistance that are contrary to these norms and values. The typical gamer is no longer a white man, and gaming culture is now acknowledged to include race and gender dynamics that are close to that of the broader population. These communal shifts have both challenged and reinforced existing power structures. This research addresses these shifts and struggles by analyzing how …

Associations Between Neighborhood Physical And Social Stressors During Sensitive Developmental Periods And Substance Use In Early Adulthood, Abigail M. Ulofoshio

Electronic Theses & Dissertations (2024 - present)

Background

Substance use is a major public health problem. Neighborhood disadvantage and related stressors have been linked to increased substance use in adolescence and early adulthood, although findings are mixed. No studies have explored whether the timing or accumulation of neighborhood stressors in childhood and adolescence impact substance use in early adulthood. This study aims to investigate to what extent physical and social neighborhood stress during sensitive developmental periods influence substance use dependency and illicit substance use in early adulthood.

Methods

We analyzed an imputed sample (n = 7,494) from the Avon Longitudinal Study of Parents and Children (ALSPAC), a …

Weighing The Costs: Understanding How Eating Disorder History And Motivation For Use Impacts Experience On A Glucagon-Like Peptide-1 Receptor Agonist And Interest In Future Use, Kimberly M. Gauert

Electronic Theses & Dissertations (2024 - present)

Glucagon-Like Peptide-1 receptor agonist (GLP-1 RA) medications have become popular tools due to their effectiveness regarding weight loss and chronic disease management. The drastic increase in demand for these medications has led to widespread availability and an increase in “off-label” use for cosmetic purposes. Although GLP-1 RA medications have the potential to positively impact overall health and wellbeing, there is also concern regarding potential misuse of these medications by those with a history of eating disorder behaviors. However, few studies to date have examined the relationship between a history of eating disorder pathology, reason for GLP-1 RA use, and current …

K-3 Literacy Teachers’ Sensemaking Of Early Literacy Policies In New York State: A Survey Study, Abigail Ferris

Electronic Theses & Dissertations (2024 - present)

Teachers must have opportunities to engage deeply in sensemaking during periods of major literacy reform, as unclear expectations can limit their ability to implement policy with fidelity. Using a cross-sectional survey design, this study explored K-3 literacy teachers’ perceptions, awareness, and factors related to their sensemaking of three science of reading literacy policies and initiatives in New York State. Findings suggested varying levels of awareness of the three literacy policies and initiatives, with teachers reporting that policy messages were communicated primarily through top-down structures, such as principals and literacy coaches within their organizations. Participants drew on personal, organizational, and external …

A Multi-Omic Approach For Understanding The Individual Roles Of Atf4 And Atf3 Upon Induction Of Different Branches Of The Integrated Stress Response, Elianna T. Cruz González

Electronic Theses & Dissertations (2024 - present)

The integrated stress response (ISR) is a critical cellular pathway that coordinates adaptation to various stressors, including endoplasmic reticulum (ER) stress, amino acid (AA) starvation, heme deficiency, and viral infection. Central to this pathway are the transcription factors ATF4 and its downstream target ATF3, which regulate gene expression programs that influence cell survival, metabolism, and immune responses. While previous studies have identified ATF3 as an antiviral factor during Zika virus (ZIKV) infection, the broader relationship between ATF3 and ATF4 across multiple branches of the ISR remains incompletely understood.

In this study, I employed multi-omic approaches to characterize the roles of …

Access To Appropriate Care, Mortality, And Cost Of Inpatient Hospitalization In Infants With Omphalocele And Gastroschisis In The United States, Treeva A. Jaff

Electronic Theses & Dissertations (2024 - present)

Congenital abdominal wall defects (AWDs), including omphalocele (OM) and gastroschisis (GS), are rare but clinically significant conditions that require immediate surgical intervention and prolonged neonatal intensive care. OM is a midline defect in which abdominal organs protrude into the umbilical cord covered by a membranous sac, while GS is a full-thickness defect typically located to the right of the umbilicus through which organs protrude without protective coverage. OM is frequently associated with major co-occurring congenital anomalies and chromosomal abnormalities, while GS more commonly occurs as an isolated defect but requires more intensive surgical management. As survival rates have improved, research …

Emotional Factors Influencing Adaptive Memory: An Examination Of The Role Of Valence In The Survival Processing Effect, Dailyn Q. Clark

Electronic Theses & Dissertations (2024 - present)

Encoding information (e.g., words) in terms of their survival value produces enhanced recall relative to encoding the same information in terms of its value to other schematically similar situations (Nairne et al., 2007). In the survival memory paradigm, a scenario focused on imagining being stranded in the grasslands of a foreign land is followed by the rating of individual words (e.g., orange, mountain) as to their relevance to that scenario (Nairne et al., 2007). Using an incidental test of memory, it is often revealed that memory for those words is higher than for those same words encoded under non-survival, control …

Social Class Differences Between Client And Therapist: A Grounded Theory Study Of Working-Class Clients' Perspectives, Micah Herman

Electronic Theses & Dissertations (2024 - present)

Although a substantial body of research highlights the importance of broaching differences related to race, ethnicity, gender, and sexual orientation in psychotherapy, considerably less attention has been paid to social class, a dimension of socio-cultural identity that profoundly shapes individuals’ life circumstances, their sense of self, and their relationships with others. In recognition of our limited understanding of how working-class clients perceive and respond to class-based cultural differences between themselves and their therapists, the present grounded theory study addressed (1) how working-class clients experience and make meaning of social class differences in the therapeutic relationship and (2) what clients see …

Learning - Augmented Stochastic Model Predictive Control For Adaptive Battery Energy Storage Operation Under Net Load Uncertainty, Muhammad Amad Asif

Electronic Theses & Dissertations (2024 - present)

Battery energy storage systems play a critical role in enabling reliable operation of power systems with high penetration of renewable energy. However, optimal control of BESS is challenging due to uncertainty in net load and electricity prices. Deterministic MPC, which relies on point forecasts, can perform suboptimally under forecast errors. SMPC addresses this limitation by incorporating uncertainty through scenario-based optimization. Nevertheless, its performance depends on fixed objective parameters, particularly the cycling penalty, which governs the trade-off between economic cost and battery utilization. This thesis develops a learning-augmented SMPC framework for battery control under net load uncertainty. The proposed approach integrates …

From Policy To Practice: Strengthening Black Intellectual Engagement In Psu’S Resr Curriculum, Chantell Wesley

Anthós

This article examines how Portland State University’s Race, Ethnicity, and Social Justice (RESR) requirement, while framed as an institutional commitment to equity and inclusion, can inadvertently reproduce White Language Supremacy within Black Studies classrooms. The central question guiding this analysis is how general education equity mandates shape the pedagogical and linguistic conditions of discipline-specific courses, particularly when those courses are positioned as service spaces for non-majors. I argue that RESR implementation often shifts instructional emphasis toward students less familiar with Black intellectual traditions, thereby displacing disciplinary rigor and marginalizing Black students’ intellectual labor.

Methodologically, this study draws on autoethnographic reflection …

Gendered Words And Patent Grant Rates: A Textual Analysis, Deborah R. Gerhardt, Miriam Marcowitz-Bitton, W. Michael Schuster, Avshalom Elmalech, Omri Suissa, Moshe Mash

Faculty Publications

Text is a vehicle to convey information that reflects the writer’s linguistic style and communication patterns. By studying these attributes, we can discover latent insights about the author and their underlying message. This article uses such an approach to better understand patent applications and their inventors.

While prior research focuses on patent metadata (i.e., filing year or gendered inventor names), we employ machine learning and natural language processing to extract hidden information from the words in patent applications. Through these methods, we find that inventor gender can often be identified from textual attributes—even without knowing the inventor’s name. This ability …

Who's Afraid Of Copyright And Ai?, Deborah R. Gerhardt

Faculty Publications

Copyright and AI need not be a copyright no man’s land. Recent decisions by the Copyright Office have gotten so much media attention that many creators are unsure if they can secure copyright protection if they use AI as a creative tool. The proposed creative control paradigm can help us all tackle the challenge of determining when works created with the assistance of AI are copyrightable. Instead of relying on long-established nuanced precedent for protecting works generated with new technology, the Copyright Office asserts that any content generated with assistance from AI tools is unprotectable. This position is radically inconsistent …

A Qualitative Study Of Undergraduate Underrepresented Minoritized Students’ Online Learning Experiences, Susanne Morris

Theses and Dissertations--Curriculum and Instruction

This dissertation reports a qualitative secondary analysis of 37 semi-structured interviews with 40 undergraduate underrepresented minoritized (URM) students. Guided by social constructionism and intersectionality, the study explores how students make sense of online learning as a sociomaterial environment, attending to perceptions of constraints, affordances, and missing or misaligned signifiers. Interviews were analyzed using Braun and Clarke’s Reflexive Thematic Analysis to examine how institutional norms and course design shape what students experience as doable, safe, and meaningful. The study offers insight relevant to research and practice in equity and online learning.

Enhancing International School Implementation Capacity: Supporting Contextualized Learning At An International Baccalaureate School In China, Christopher J. Hayden Iv

Theses and Dissertations--Educational Leadership Studies

International schools allocate substantial resources to implement progressive curricular innovations; however, the advantages offered by these developments are contingent on their effective execution within classroom settings. This mixed methods action research (MMAR) study examined the implementation of the International Baccalaureate (IB) Global Context (GC) Strategy in the Middle Years Programme (MYP) at an international school in China and asked how the school might strengthen its capacity to enact this and similar innovations. Following a sequential MMAR design, a reconnaissance phase combined a whole-staff survey (n=87) with qualitative interviews to diagnose the individual, organizational, and contextual factors shaping implementation. Analyses identified …

Biomechanical Effects Of Exercise-Based Interventions In Chronic Nonspecific Low Back Pain: A Systematic Review And Meta-Analysis, Lara De Vecchi Machado

Theses and Dissertations--Kinesiology and Health Promotion

Chronic nonspecific low back pain (CNLBP) is the leading cause of years lived with disability worldwide and represents a complex, multifactorial, and heterogeneous condition. It is characterized by substantial interindividual variability in muscle activation patterns, lumbo-pelvic coordination, and movement strategies. Although exercise is widely recommended as a first-line intervention and its clinical benefits are well established, the biomechanical mechanisms underlying functional improvement remain fragmented in the literature and are rarely synthesized quantitatively.

This dissertation conducted a systematic review with meta-analysis to investigate the biomechanical effects of exercise-based interventions in individuals with CNLBP. A total of 39 studies were included and …

Are Multiple-Choice And Open-Ended Assessments Consistent In Predicting Science Achievement? Multivariate Multilevel Evidence From Chinese Students And Schools, Quan Wu

Theses and Dissertations--Education Sciences

A multivariate multilevel model was developed and applied to secondary data from a large-scale science assessment of Grade 8 students in China to examine the consistency between multiple-choice and open-ended formats of assessment in predicting science achievement at the student and school levels. The sample included 44,534 students from 159 schools across two regions. Multivariate multilevel results indicated a moderately positive consistency between the two formats at the student level and a strongly positive consistency at the school level; these consistencies were stable across regions and did not depend on student and school characteristics. The findings have important practical implications …

Bridging The Intention–Behavior Gap In Mental Health Help-Seeking, Wenqi Weng

Theses and Dissertations--Educational, School, and Counseling Psychology

Objective: To examine whether modifiable factors shape the extent to which help-seeking intention is translated into formal mental health service initiation among distressed adults. Method: Participants were U.S. adults (N = 777; M age = 47.21 years, SD = 16.70; 73.23% women; 77.74% White) who reported at least moderate psychological distress and were not currently receiving formal mental health treatment. At baseline, participants completed measures of help-seeking intention, focal moderators (action planning, psychological distress, and mental health steward self-identity), coping planning, cues to action, and emotion regulation as exploratory candidate moderators. At three-month follow-up, participants reported whether …

A Historical Case Study Of The Effects Of The Coordinate Interagency Partnership Regulating International Students (Cipris) System And The Student Exchange Visitor Information System (Sevis) On Foreign Students Coming To The United States For Higher Education From 1990 To 2008, M. Ann Livingstone

Theses and Dissertations--Educational Policy Studies and Evaluation

The United States has welcomed foreign scholars and students since 1774, but their numbers increased dramatically after World War I, and again after World War II, as America became a world power leader and interest in the United States and its educational system and technological developments grew internationally. The Immigration and Naturalization Service (INS) was set up to oversee immigrants, visitors, and nonimmigrants who included students and diplomatic staff and families. This study deals with the changing laws and responsibilities of the INS during the period 1990 to 2008 to track foreign students in higher education, specifically with the introduction …

Contractual Democracy From Statehouse To School Board: Shifts In Legislation And School Board Authority In Kentucky, Hannah M. Edelen

University of Kentucky Doctoral Dissertations

School boards have long been regarded as a cornerstone of American democracy, providing local governance over public education. While considerable scholarship highlights the increasing involvement of state and federal governments in education, relatively few studies examine with specificity how legislatures shape the local authority of these governance structures. This study investigates how the Kentucky State Legislature has influenced the authority of local school boards over three legislative sessions (2020–2022) and how board members perceive their evolving role. Using a multi-method approach and conceptualized in principal-agent theory, this research contributes to understanding how legislatures shape the governing responsibilities of school boards …
