A Conventional Solution To Constitutional Stagnation?, David E. Pozen

Faculty Scholarship

Our charter of government is stuck. The last time the U.S. Constitution was revised was over 30 years ago, when the “fluky” and largely inconsequential Twenty-Seventh Amendment stole into the text two centuries after it was written. The last time Congress proposed an amendment was almost 50 years ago, when the District of Columbia Voting Rights Amendment was sent to its demise at the ratification stage. Although state constitutions remain far more dynamic, they too have experienced a declining rate of amendment in recent years.

Shifting To Using Desmos Or Geogebra Graphing Calculators In High School Mathematics Classrooms, Nancy Lin

Dissertations, Theses, and Capstone Projects

Most high school math classrooms in Long Island use the Texas Instruments TI-84+ CE graphing calculator in the three Regents math courses. Texas Instruments holds approximately 80% of the market share of the international graphing calculator market. At a manufacturer's suggested retail price of $150 per TI-84+ CE, an inequitable situation exists for math learning, as underfunded schools and students from lower socioeconomic backgrounds cannot afford to purchase one for home use. Such students have less experience using the handheld graphing calculator when they take high-stakes math exams. Through case studies of four suburban school districts in New York that …

Social Media-Based Social Comparisons Among Socially Anxious Young Adults: The Role Of Cognitive Reappraisal, Jennifer L. De Rutte

Dissertations, Theses, and Capstone Projects

Social media is a central context for social interaction and self-evaluation among young adults. For those with elevated social anxiety, these environments may be especially salient because they provide frequent opportunities for social comparison. Although upward social comparison on social media has been linked to poorer emotional outcomes, less is known about its experimental effects among socially anxious young adults or whether upward and downward comparison have distinct effects that extend to later socially evaluative situations. The present study examined these questions in 84 socially anxious young adults randomly assigned to view simulated Instagram feeds eliciting upward comparison, downward comparison, …

Potential Energy Landscape Formalism For Quantum Liquids, Yang Zhou

Dissertations, Theses, and Capstone Projects

Atomic delocalization due to nuclear quantum effects (NQE) remains poorly understood in low-temperature liquids near the glass state and during vitrification. Many liquids can be described accurately by treating their nuclei as classical particles, but this approximation fails for light elements such as He and H₂, small hydrogen-containing molecules such as water, and systems in which zero-point motion or isotope-substitution effects are important. Developing a general thermodynamic and statistical-mechanical description of such liquids has been challenging. This dissertation extends the potential energy landscape (PEL) formalism, originally developed for classical liquids and glasses, to liquids that obey quantum mechanics and exhibit …

Modeling And Generating Trustworthy Speech, Yuwen Yu

Dissertations, Theses, and Capstone Projects

As virtual agents become increasingly integrated into everyday communication, trust has become essential for effective human-AI interaction. Although recent advances in natural language generation and speech synthesis have significantly improved fluency and intelligibility, most systems are not designed to control how trustworthy they are perceived. As a result, a mismatch can emerge between perceived trustworthiness and actual system capability, leading to over-trust or under-trust. While trust is critical for meaningful interaction, current text-to-speech (TTS) systems are primarily optimized for naturalness and intelligibility rather than calibrated trustworthiness.

This dissertation investigates the perceptual foundations of trust in both human and synthesized speech …

"Is This America?" Fannie Lou Hamer, Humanity, Citizenship And The Struggle For Inclusive Democracy, Rhonda Chambers

Dissertations, Theses, and Capstone Projects

This thesis examines the life, political rhetoric, and enduring legacy of Fannie Lou Hamer, focusing on how her lived experiences under Jim Crow shaped the development of a distinctive political voice grounded in dignity, moral conviction, and democratic struggle.  Born into a Mississippi sharecropping family and denied the educational and political opportunities afforded to white Americans, Hamer developed an understanding of injustice through the realities of racial and economic oppression. Her experience with segregation, voter suppression, violence, and the Black church became central to the way she understood citizenship and was able to articulate the demands of freedom.

Through an …

The Effects Of Chronic Nicotine Exposure On Dopamine-Mediated Reinforcement Learning And Striatal Neurotransmission, Srishti Bose

Dissertations, Theses, and Capstone Projects

Tobacco is one of the most widely used substances across the United States; tobacco consumption is linked with several diseases and is one of the leading causes of preventable death in the country. Nicotine is the active substrate found in tobacco products, acting as a stimulant, which reinforces continued use. The introduction of tobacco-free options such as e-cigarettes and oral pouches has driven an increase in nicotine exposure across the population, especially in young adults. Acute nicotine use induces neuroadaptations in the mesolimbic dopaminergic system, which mediates reinforcement learning and addiction, that potentiates reward-related neurotransmission. Furthermore, there are clinical studies …

Individual Intellectual Humility As A Predictor Of Perceived Information Sharing And Perceived Shared Leadership, Mary Beth Schroeder

Dissertations, Theses, and Capstone Projects

Cross-functional problem-solving teams are often assembled to address complex challenges by combining members’ distinct knowledge, ideas, and leadership capabilities. Yet teams do not always capitalize on these collective resources, because team members do not share the information they uniquely possess. This tendency to withhold information may be lessened by intellectually humility, a personality trait marked by a desire to close gaps in one’s knowledge and openness to what others contribute.

This study was originally designed to examine whether team intellectual humility relates to team creativity through information sharing and shared leadership. However, because of changes in the leadership development program …

The Role Of Temperament In Criminal Trajectories: Development, Stability, And Predictive Power Across The Life Course, Joshua A. Lang

Dissertations, Theses, and Capstone Projects

Temperament, an individual's largely innate tendency to experience and regulate responses to their environment, has long been studied but was only recently introduced as a primary predictor of criminal behavior (DeLisi & Vaughn, 2014). While prior criminological theories have incorporated temperament-related constructs, such as negative affect (Agnew, 1992; Moffitt, 1993) and self-control (Gottfredson & Hirschi, 1990), no other theory has explicitly positioned temperament as the central factor in offending. DeLisi and Vaughn’s temperament-based theory of antisocial behavior posits that individuals with low effortful control and high negative emotionality—features of a difficult temperament—are more likely to engage in criminal behavior. Despite …

The Role Of External Factors In Shaping Carbohydrate Conformational Landscapes, Murat Yaman

Dissertations, Theses, and Capstone Projects

Carbohydrates (glycans) are among the most structurally diverse biomolecules and participate in a wide range of biological processes, including molecular recognition, cell adhesion, immune response, host-pathogen interactions, and cellular signaling. Their biological functions are governed by a complex interplay between sequence, stereochemistry, conformational flexibility, and environmental factors. However, the structural heterogeneity and dynamic nature of glycans present significant challenges for both experimental characterization and theoretical modeling. In particular, the relationships between glycan structure, conformational dynamics, and the resulting potential energy surfaces remain incomplete.

This dissertation investigates how external factors modulate the potential energy surfaces of carbohydrates through a combination of …

Self-Organized Criticality In Biased Activated Random Walk, Joshua Meisel

Dissertations, Theses, and Capstone Projects

We demonstrate many of the conjectured universality and self-organized criticality (SOC) properties of the interacting particle system Activated Random Walk (ARW) in the setting of one-dimensional biased walks, as formulated for instance in Levine and Silvestri’s 2024 survey. Namely, there exists the same limiting critical state for two finite ARW models, as well as for the infinite model as the density approaches its critical value from below. Many of the desired properties hold, including heavy-tailed avalanches, but spatial correlations decay exponentially fast, a deviation from the SOC paradigm. Nonetheless, the obtained decay rate vanishes with the bias. Since the critical …

Opportunities For Learning Through Object Exploration During Early Physical Therapy: Physical Therapists’ And Caregivers’ Assistance And Interference Behaviors, Michele Goncalves Maia

Dissertations, Theses, and Capstone Projects

Early physical therapy (EPT) for infants with motor delays has traditionally emphasized motor milestone acquisition, yet growing evidence indicates that motor and cognitive development are fundamentally interconnected. Grounded in embodied cognition and developmental cascade theories, this dissertation conceptualized object exploration as a primary mechanism through which infants learn during EPT and examined how intervention approaches and adult behaviors shape opportunities for object exploration. Using retrospective analyses of video-recorded EPT sessions, two studies investigated how intervention approaches and adult behaviors influence infants' opportunities to learn through object exploration. Study 1 compared object exploration in the START-Play (SP) intervention and Usual Care …

Sedentary Behaviors And Functional Disability Among Chinese Older Adults (2008–2018): Evidence Including Mahjong, Yen-Han Lee, Yen-Chang Chang, Minzhi Ye, Cai Xu

School of Social Work Faculty Publications

Purpose: This study examined how different types of sedentary behavior relate to changes in functional disability, measured by activities of daily living (ADL) and instrumental activities of daily living (IADL), among Chinese older adults.

Major findings: Using data from 17,939 participants in four waves (2008–2018) of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), sedentary behavior was categorized into four types: none, playing mahjong only, combining these with other sedentary activities, and other activities alone (e.g., reading and watching TV). Cox two-state regression models estimated the hazard of transitioning in ADL and IADL disability. Engaging in sedentary behaviors was generally …

The Impact Of Stigma On The Mmpi-3 Scores Of An Indo-Caribbean Community Sample, Julia Persaud-Naipaul

Theses and Dissertations

Evaluation of personality and psychological disorders is accomplished through the use of psychometric measures. However, tests require interpretation of test responses using a normative criterion based on a particular population that may not fully consider the effect of cultural influences on an individual’s level of willingness to report psychological difficulties. For example, individuals in collectivistic cultures may not be as willing to self-report problems because mental illness is often perceived as a source of embarrassment and shame. One culturally unique population that has been overlooked in psychological assessment is the Indo-Caribbean population. Their specific cultural values, beliefs, attitudes, and practices …

Using Early And Periodic Screening, Diagnostic, And Treatment (Epsdt) To Improve Access To Obesity Pharmacotherapy: A Practical Guide For Clinicians Caring For Youth With Obesity Across United States Medicaid Programs:, Jaime M. Moore, Valerie M. O'Hara, Cassie Totman, Brooke Sweeney, Sarah Hampl, Alaina P. Vidmar

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Coverage of obesity pharmacotherapy for youth varies substantially across state Medicaid programs. This variability limits access to evidence-based treatment for pediatric obesity. The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit is a federally mandated Medicaid provision requiring coverage of medically necessary services for individuals under age 21, even when such services are not included in standard state Medicaid benefits. Despite its broad scope, EPSDT remains underutilized due to limited awareness and operational complexity.

METHODS: We developed a clinician-facing, practice-oriented framework to operationalize EPSDT for pediatric obesity treatment. This approach integrates (1) review of federal EPSDT policy and …

Becker, Laura Ramsey, Susan D. Thompson, Carl D. Langefeld, Federica Corba, Edoardo Marrani, Gabriele Simonini, Gabriele Stocco, Giuliana Decorti, Andrea Taddio, Serena Pastore

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: Methotrexate (MTX) is the first-line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro.

METHODS: ITPA enzymatic activity was measured by high-performance liquid chromatography with ultraviolet detection in erythrocyte lysates from patients with JIA (enrolled in Trieste, Italy; Florence, Italy; and Kansas City, Missouri) receiving weekly MTX (10-15 mg/m²) for at least 12 months. Remission was evaluated by Wallace et al criteria. ITPA rs1127354, which …

Fridley, Shelley S. Tworoger, Kathryn L. Terry

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Non-hormonal intrauterine devices (IUDs) create an inflammatory uterine environment while oral contraceptives (OC) suppress ovulation and have different associations with ovarian cancer risk. We have evaluated the associations of these two contraceptive exposures with ovarian tumor immune infiltration.

METHODS: This study assessed associations of IUD and OC use with tumor immune features via multiplex immunofluorescence in 24 ovarian tumor tissue microarrays from four case-control and two cohort studies. Multivariable-adjusted beta-binomial models estimated the odds of tumor T cell positivity by contraceptive history.

RESULTS: High-grade serous tumors had the highest percentage of tumor cells positive for total T cells (CD3+ …

The Rise And Fall Of Lateral Electrical Surface Stimulation (Less) Through The Lens Of Srs Archives., Ali Rezazadeh Shirazi, Jay I. Kumar, Katie Dold, George H. Thompson, Andrew G. King, Richard M. Schwend, John P. Lubicky, Jay Shapiro, Behrooz A. Akbarnia, History Committee Of The Scoliosis Research Society

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: Lateral electrical surface stimulation (LESS), commercially known as the ScoliTron™, emerged in the late 1970s as a noninvasive alternative to bracing for adolescent idiopathic scoliosis. Early clinical reports generated considerable enthusiasm and adoption, but the technique was ultimately abandoned. This study examined the rise and fall of LESS through a combined analysis of the Scoliosis Research Society (SRS) archives and published literature, with the goal of understanding factors that influence the adoption, evaluation, and abandonment of innovation in scoliosis care.

METHODS: A structured historical review was conducted using archival materials from the Scoliosis Research Society (SRS), including meeting abstracts, …

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Congenitally corrected transposition of the great arteries (ccTGA) is a rare disorder. Here, we evaluated the effectiveness of physiological, anatomical and Fontan repair techniques for ccTGA.

METHODS: A systematic database search in PubMed, Embase and Cochrane Central Register of Controlled Trials was conducted from inception to 5 June 2023. Random-effects network meta-analysis was performed, comparing mortality, postoperative arrhythmias, reintervention after definitive surgery and transplant-free survival in patients undergoing physiological, anatomical and Fontan repair.

FINDINGS: A total of 1,209 patients were included from nine studies. Fontan repair was associated with a higher rate of transplant-free survival (absolute risk [AR] 0.999 …

Patient-Specific Computational Fluid Dynamics Modeling Of Airway Collapse In Infants With Robin Sequence., Gautam Jalori, Michael Barbour, Michael Bindschadler, Kelly Evans, John P. Dahl, Alberto Aliseda

Manuscripts, Articles, Book Chapters and Other Papers

Robin Sequence (RS) is a congenital condition in which patients experience dynamic, periodic obstruction or collapse of the upper airway due to an underdeveloped jaw and a posteriorly displaced tongue. Current clinical techniques for evaluating airway obstruction do not provide quantifiable data and fail to account for the dynamic nature of obstruction or collapse. There is no standardized criterion to characterize obstruction or collapse severity. This study presents the first method that extracts airway motion from 4-dimensional computed tomography and performs a patient-specific, moving-mesh computational fluid dynamics (CFD) analysis of RS patients with complete airway collapse or obstruction. To quantify …

Irs: Iterative Reference Selection Improves Normalization Of Microbiome Sequencing Data, Yiming Shi, Lili Liu, Jun Chen, Kristine M Wylie, Todd N Wylie, Sung Hee Park, Ruiwen Zhou, Yin Cao, Stephanie A Fritz, Molly J Stout, Maria Cristina Vazquez Guillamet, Lei Liu

2020-Current year OA Pubs

Microbiome studies often seek to determine how the absolute abundances of individual taxa change across biological conditions, yet sequencing read counts are sample-specific scaled representations of those abundances. Because sampling depth can differ across samples, fold changes calculated directly from sequencing read counts do not generally represent absolute-abundance fold changes. Normalization methods attempt to account for these between-sample differences in sampling depth, but their accuracy depends on the reference used. In particular, total-sum scaling uses all taxa as the reference and can introduce compositional bias. Reference-based methods instead rely on taxa that are stable across conditions, but contamination of the …

Cracking The Code: Genotype-Phenotype Correlation Models In Sarcoglycanopathies, Leonela Luce, Conrad C Weihl, Et Al.

2020-Current year OA Pubs

OBJECTIVE: Sarcoglycanopathies are among the most severe limb-girdle muscular dystrophies (LGMD), though milder presentations have been described. These diseases are primarily caused by missense variants, but the limited predictability of their effect on protein maturation, complex formation, and transport has hindered reliable genotype-phenotype correlations. This study aimed to establish accurate genotype-phenotype correlations for LGMDR3, LGMDR4, and LGMDR5.

METHODS: We analyzed the largest sarcoglycanopathy cohort to date (n = 541). Clinical data, including age at symptom onset and loss of ambulation, were collected and used to define phenotype severity. Predictive models were developed considering the impact of non-truncating variants on secondary …

The spinal cord plays a central role in the pathophysiology and clinical manifestations of multiple sclerosis (MS), yet remains under-studied compared with the brain. This review summarizes key insights from the 2025 North American Imaging in MS Spinal Cord Imaging Workshop, highlighting recent advances, ongoing challenges, and future opportunities in MS spinal cord imaging. We review pathological studies and outline the clinical relevance of spinal cord lesions and atrophy for diagnosis, prognosis, and disease monitoring, highlighting emerging biomarkers of progression independent of relapse activity. Correlations between magnetic resonance imaging, histopathology, and clinical outcomes support the validation and translational potential of …

Harkness Seminars In The Humanities, Sarah S. Novlan

Electronic Theses and Dissertations

This participatory action research study explored the effects of Harkness seminars on students’ cognitive, affective, and metacognitive learning in secondary humanities classes. Educators need an effective, flexible, and adaptive method to promote student learning beyond superficial content acquisition. With the decoupling of virtue formation from knowledge acquisition, knowledge gaps from COVID-19 lockdowns, and the rise of artificial intelligence in student plagiarism, a proven method to address all aspects of student formation is needed. Using a participatory action research framework for this qualitative study, conducted at an independent K–12 school site in Texas, the researcher interviewed six secondary humanities teachers over …

Nurses' And Families' Experiences Of A Feasibility Trial Comparing Single‐Use And Multiple‐Use Endotracheal Suction Catheters In Mechanically Ventilated Patients: A Qualitative Study, Mohamed H. Eid, Kevin Hambridge, Patricia Schofield, Jos M. Latour

School of Nursing and Midwifery

BackgroundIn resource-limited Intensive Care Units (ICUs), reusing endotracheal suctioning catheters is often standard practice due to supply constraints or staffing pressures. Randomised controlled trials (RCTs) have explored the impact of these practices on patient outcomes. However, less is known about the experiences of nurses and family members involved in RCTs testing endotracheal suctioning interventions.AimTo explore the experiences of ICU nurses and family members participating in a feasibility RCT comparing single-use versus multiple-use endotracheal suction catheters flushed with chlorhexidine or normal saline in a resource-limited ICU setting.Study DesignA qualitative study was embedded within a feasibility RCT. Semi-structured interviews were conducted with …

Longstanding Mental Representations Of Familiar Faces, Sarah Laurence, A. Mike Burton, Camilla During, Jennifer Pink, Lucy Wilson, Mila Mileva

School of Psychology

As we recognise people we know over many years, their faces can change, sometimes profoundly, and yet we continue to recognise them with ease. How do we update our representations over time? We present four pre-registered experiments to examine this. In Experiment 1, using likeness ratings and speeded name verification, fans of a long-running TV soap opera demonstrated that their representations of the characters’ faces were weighted towards their most recent encounters – when the characters were oldest. While we initially hypothesised that this was due to recency, Experiment 2 showed this not to be the case. When new participants …

An Investigative Approach Leveraging Digital Twin Technology For A Cnc Machine, Anand Valiavalappil

Yanbu Journal of Engineering and Science

Digital twin technology has emerged as an effective approach for improving the monitoring, validation, and optimization of Computer Numerical Control (CNC) machining operations.
