An Investigation Into The Scottsdale Art Week: Cultural Focus, Location, And Sustainability In An Already Saturated Environment, Sophia K. Meshel

MA Theses

This thesis examines the role of regional art fairs within the wider American art market and examines how these events contribute to the growth of local cultural artistic ecosystems. While firmly established international art fairs often dominate attention within the global market, lesser known regional fairs play an important role in connecting artists, galleries, collectors, and cultural platforms within specific communities. Through analysis of established regional fairs and consideration of factors such as artist selection, audience engagement, institutional partnerships, and economic impact, this study investigates how art fairs can move beyond temporary commercial events to become meaningful cultural platforms. Particular …

Echoes Of A Country In Question: Visualizing And Constructing Lebanese Identity Through Contemporary Artistic Practice At The Venice Biennale, Anoush Manoukian

MA Theses

Historically (and presently) riven by sectarianism, struggling with massively degraded infrastructure, and seething with starkly apparent class divisions, Lebanon has long been tied up with bloody postwar politics, paralyzed by innumerable crippling setbacks on its path to recovery. During war, images of conflict have been plastered across media stations, firming the country’s place in the global conversation and imagination; everyone had heard about Lebanon, and people from the art world were attracted to the work being produced in Beirut: a localized body of work that was thematically interesting, formally unique, aesthetically neoconceptual and allegorical in approach. Unresolved conflicts have long …

A Position Statement On Endovascular Models And Effectiveness Metrics For Mechanical Thrombectomy Navigation, On Behalf Of The Stakeholder Taskforce For Artificial Intelligence-Assisted Robotic Thrombectomy (Start), Harry Robertshaw, Anna Barnes, Phil Blakelock, Raphael Blanc, Robert Crossley, Rebecca Fahrig, Ameer E. Hassan, Benjamin Jackson, Lennart Karstensen

School of Medicine Publications

Although we are making progress in overcoming infectious diseases and cancer, one of the major medical challenges of the mid-21st century will be the increasing prevalence of stroke. Occlusions in large vessels are especially debilitating, yet effective treatment—needed within hours to achieve best outcomes—remains limited because of geographic accessibility. One solution for improving timely access to mechanical thrombectomy in geographically diverse populations is the widespread deployment of robotic surgical systems. Artificial intelligence assistance may enable the safe and effective upskilling of operators in this emerging therapeutic delivery approach. Our aim was to establish consensus frameworks for developing and validating artificial …

Tuberculosis Presenting As Multiple Pulmonary Nodules Mimicking Malignancy, Abdel Martinez Borrego, Fatimah Bello, Brandon Cantazaro, Luisa Montoya, Frank Mediola

School of Medicine Publications

Multiple pulmonary nodules often raise concern for metastatic malignancy; however, the differential diagnosis is broad and includes infectious, inflammatory, granulomatous, vascular, and benign etiologies. Tuberculosis (TB), although uncommon, can present with multiple nodules that closely mimic metastatic disease on advanced imaging, requiring careful clinicoradiologic and microbiologic correlation. We describe a woman in her 50s who presented with dyspnea and new-onset heart failure, in whom imaging revealed mediastinal lymphadenopathy and bilateral pulmonary nodules concerning for malignancy. Evaluation was limited by concurrent COVID-19 infection, and CT-guided biopsy demonstrated necrotizing granulomas without evidence of malignancy or infection. She later re-presented with fever and …

The Association Between Maternal-Fetal Medicine Physician Density And Pregnancy Outcomes, Tetsuya Kawakita, Rula Atwani, Misa Hayasaka, Lindsay Robbins, George Saade

Department of Obstetrics & Gynecology Faculty Publications

Objective

We sought to examine the association between maternal-fetal medicine (MFM) physician density and adverse pregnancy outcomes at the state level.

Study Design

This was a cross-sectional analysis of publicly available, state-level data from 2018 to 2021, including Natality, Multiple Cause-of-Death, and Fetal Death databases. The number of active MFM physicians per year was obtained for each state from the American Medical Association Masterfile. The primary exposure was the density of MFM per state, categorized into three groups: (1) low density (< 30 MFM physicians per 100,000 live births), (2) moderate density (30-59 MFM physicians per 100,000 live births), and (3) high density (≥60 MFM physicians per 100,000 live births). Our primary outcome was maternal mortality during pregnancy and up to 42 days postdelivery. Our secondary outcomes were pregnancy-related mortality up to 365 days postdelivery and stillbirth. We calculated adjusted incident rate ratios (aIRR) and average marginal effect (AME) with 95% confidence intervals (95% CI) using multivariable negative binomial mixed effects regression models.

Results

Overall, there were 14,792,743 live births, 3,440 maternal mortalities, 4,980 pregnancy-related mortalities, and 90,848 stillbirths included. The …

Department of Obstetrics & Gynecology Faculty Publications

OBJECTIVE:

To examine the association between neighborhood-level social determinants of health and stillbirth.

METHODS:

We performed a retrospective cohort study of deliveries that occurred at a gestational age of at least 20 weeks within a five-hospital system (2012-2022). Electronic health record data mapped to the Observational Medical Outcomes Partnership Common Data Model were geocoded using addresses at the time of delivery and linked to neighborhood health indices, which included the Area Deprivation Index (ADI), Maternal Vulnerability Index (MVI), and Social Vulnerability Index (SVI) at the Census tract level. Stillbirths were adjudicated by medical record review. Modified Poisson regression generated relative …

Mediating Effect Of Social Determinants Of Health Between Race And Phthalate Biomarkers In Pregnancy, Tetsuya Kawakita, Misa Hayasaka, Carole Barake, Trinity Soto, Jillian Fleming, Amir Lueth, Stevens Danielle, Alfred Abuhamad, Ann Pryzybylska, Elena Sinkovskaya, Kelly K. Ferguson, George Saade

Department of Obstetrics & Gynecology Faculty Publications

Introduction

Prenatal phthalate exposure is linked to adverse reproductive and developmental outcomes and is consistently higher among non‐Hispanic Black compared to non‐Hispanic White pregnant individuals, yet the factors responsible for these disparities are poorly characterized. We sought to quantify Black–White differences in repeated urinary concentrations of phthalate biomarkers during pregnancy and to estimate the extent to which neighborhood‐level social determinants of health (SDoH) mediate these disparities.

Methods

This secondary analysis used data from the Human Placenta Project Study, a prospective observational cohort study conducted at two academic institutions between 2016 and 2018. Eligible participants had singleton pregnancies, were recruited before …

Department of Obstetrics & Gynecology Faculty Publications

Background

Diabetes mellitus (DM) imposes substantial healthcare costs with documented disparities among African Americans and Hispanic patients. To inform care delivery and resource allocation, this study identified hospitalization cost predictors among African American and Hispanic patients with diabetes in Southeastern Virginia.

Methods

We analyzed 6,011 hospital discharges from the Virginia Health Information database (2016-2020) for adults aged 18-85 with diabetes. Discharges were classified by Medicare Severity Diagnosis-Related Groups: DM with complications/comorbidities (DCC, n = 3,328), DM with major complications/comorbidities (DMCC, n = 1,518), and DM without major complications/comorbidities (DWO, n = 1,165). Because cost distributions were right-skewed (skewness 3.5-8.24), we …

Contribution Of Comorbidities And Pregnancy Complications To Severe Maternal Morbidity In The United States, Tetsuya Kawakita, Sora A. Jones, Natsume Furukawa, George Saade

Department of Obstetrics & Gynecology Faculty Publications

Objective: To quantify the extent to which rising rates of severe maternal morbidity (SMM) in the United States from 2016 to 2022 are attributable to increasing prevalence of maternal risk factors, including advanced maternal age, obesity, pregestational diabetes mellitus, gestational diabetes, chronic hypertension, and hypertensive disorders of pregnancy (HDP).

Methods: We conducted a retrospective cohort study using the Nationwide Readmissions Database from 2016 to 2022, representing more than 25 million weighted delivery hospitalizations. The primary outcome of SMM was identified with the Centers for Disease Control and Prevention's 21-condition algorithm; a secondary outcome excluded transfusion to improve specificity. Temporal trends …

Cervicovaginal Lavage Fluid Iron And Manganese Levels In Women With And Without Vaginitis, Barbara Kozma, David Ratonyi, Bence Kozma, Peter Takacs, Attila G. Sipos

Department of Obstetrics & Gynecology Faculty Publications

Transition metals such as iron and manganese are critical for cellular metabolism, redox balance, and immune function, and they also influence host–pathogen interactions. Vaginitis is characterized by mucosal inflammation that may alter local trace-element homeostasis. We hypothesize that inflammatory conditions such as vaginitis may be associated with altered cervicovaginal iron and manganese levels. We performed a prospective, single-center cohort study at the University of Debrecen (Hungary) between April 2023 and April 2024, enrolling 80 women ≥ 18 years with vulvovaginal complaints. Participants were assessed at baseline and at weeks 4, 8, and 12 with clinical evaluation and cervicovaginal lavage (CVL) …

Comparisons versus placebo were made using a mixed-effects model for …

The Association Between The Degree Of Social Vulnerability And Maternal Anemia And Other Adverse Perinatal Outcomes, Rubymel J. Knupp, Christina T. Blanchard, Ariann Nassel, Ashley Shea, Lindsay S. Robbins, Jeff M. Szychowski, Ashley N. Battarbee, Akila Subramaniam

Department of Obstetrics & Gynecology Faculty Publications

Objective

Maternal anemia in pregnancy is associated with many adverse maternal, fetal, and neonatal outcomes. The role of social determinants of health (SDOH) in the development of maternal anemia and other adverse outcomes is continually evolving. One such newer tool, the Social Vulnerability Index (SVI), measures an individual's community-level SDOH, with higher SVI denoting higher vulnerability. Our objective was to evaluate the association between SVI, maternal anemia, and other adverse perinatal outcomes.

Methods

Retrospective cohort study of pregnant individuals delivering singletons at a gestational age ≥23 weeks at a single center from 2014 to 2018. Patients with sickle cell disease, …

Moyd, Elena Sinkovskaya, Ann Przybylska, Antonia M. Calafat, Julianne C. Botelho, George Saade, Alfred Abuhamad, Kelly K. Ferguson

Department of Obstetrics & Gynecology Faculty Publications

Background

Gestational exposure to phthalates is higher among non-Hispanic black (NHB) women than non-Hispanic white (NHW) women and may contribute to racial/ethnic differences in birthweight z-scores.

Objective

We aimed to investigate whether gestational phthalate and replacement biomarkers mediate the association between race/ethnicity and birthweight z-scores.

Methods

We analyzed data from 271 pregnancies in the Human Placenta and Phthalates study, a prospective cohort recruited from 2017 to 2020. Urinary phthalate metabolite concentrations were measured at up to eight time points during pregnancy and averaged to represent gestational exposure. Metabolites were grouped by parent compound. Linear regression models estimated associations in phthalate …

"I'M Going To College": Protective Factors Shaping The College-Going Identity Of Prospective First-Generation College Students Of Color, Joseph M. Williams, Yakob Lemma, Nina R. Schoonover, Morgan Rustia, Ben Allen

Journal of College Access

A college-going identity reflects a mindset in which individuals view college as a realistic, attainable, and desirable goal. It is characterized by the belief that higher education is a vital part of one's educational journey and is accompanied by a strong aspiration to earn a degree. For students from low-income and marginalized backgrounds, this identity serves as a critical protective factor, buffering against systemic inequities, resource limitations, and low expectations that often shape their educational experiences. This qualitative study examines the protective factors shaping the college-going identity of prospective first-generation, low-income middle school students of color (N = 17). Centering …

Reframing Narratives, Reclaiming Futures: Antiracist School Counseling And Black And Brown Girls In Stem, Renae D. Mayes, Lia D. Falco, Shontell Zenon, Dequindre Hughes, Yijia Chen, Lydia Ross, Medha Dalal

Journal of College Access

Black and Brown girls often have educational experiences that stifle their career aspirations, especially in STEM fields. These experiences can be exacerbated by educators who misunderstand and refuse to recognize their STEM potential, thus limiting their opportunity to build STEM identities. School counselors can disrupt these experiences through antiracist practices that cultivate homeplace and joy for Black and Brown girls to heal and grow while working to address harmful policies and practices. In this paper, authors discuss how school counselors can specifically use antiracist school counseling practices to support Black and Brown girls in STEM as a part of multi-tiered …

College Vs. Career School Counseling: How Role Differentiation Shapes Student Postsecondary Expectations And Outcomes, Sam Luby

Journal of College Access

This study examines how high school counselor role differentiation, specifically college preparation and workforce readiness, relates to students’ postsecondary expectations (2012) and early outcomes (2016) using nationally representative data from the High School Longitudinal Study of 2009 (HSLS:09). Multinomial logistic regression models controlling for academic achievement and socioeconomic factors indicate that the presence of college-preparation counselors significantly reduces the likelihood of students entering the workforce without postsecondary enrollment.

Workforce-preparation roles show no statistically significant association with postsecondary outcomes, though they are more common in schools serving higher-need populations. Academic performance and poverty status remain strong predictors across models. Findings underscore …

The Limits Of Daca: Affordability- And Access-Related Barriers To Health Professions Education, Nicole Perez, Laura Hirshfield

Journal of College Access

The U.S. is currently facing a shortage of health professionals from underrepresented backgrounds. One potential pathway to decrease this shortage is through the Deferred Action for Childhood Arrivals (DACA) program, a policy that provides temporary relief from deportation for individuals who migrated to the U.S. before age 16. This study, using 15 life-history narrative interviews, investigates the experiences of Latinx young adults who were pursuing health professions education or working as health professionals. Nine of the participants were DACA recipients, while the remaining six were second-generation (i.e., children of immigrants). An iterative, inductive approach to data analysis was used to …

Methods For Inter-Sensor Radiometric Harmonization Of Planetscope Superdove Constellation, Biraj Bikram Pathak

Theses

The PlanetScope SuperDove constellation consists of approximately 130 CubeSats. Radiometric drift among the satellites degrades time-series workflows. We formulate inter-sensor harmonization as a supervised regression problem and train a single model across all eight spectral bands using overlapping regions from cross- sensor image pairs. Controlled experiments on same-day image pairs show that a cubic spline model with 20 uniform knots and joint Ridge regularization achieves the lowest error among the evaluated per-pixel regression approaches. The model converges to a Kullback-Leibler divergence between 0.001 and 0.003, and no alternative architecture studied achieves a statistically significant improvement. Models that fit on each …

A Firm’S Operational Risk: Data Set And Empirical Evidence, Vivek Astvansh, Joseph J. Simpson

International Business and Entrepreneurship Faculty Publications

Problem definition: A firm’s stakeholders would benefit from a quantitative measure of the managerial disclosure of its operational risk and the implications of this disclosure. However, a quantitative and scalable measure of a firm’s disclosed operational risk is unavailable. Thus, the firm’s stakeholders remain unaware of its disclosed operational risk and the risk’s implications. Methodology/results: U.S. law requires a public firm to textually disclose its operational and nonoperational risks in Item 1A of its annual report (i.e., Form 10-K). We train 64 transformer models on U.S. public firms’ Item 1A text to score 131,920 firm-years (16,959 firms, 2005 to 2024) …

From Designation To Implementation: A Qualitative Study Of Support Structures For Latinx Students At A Hispanic-Serving Institution, Steven A. Freeman

Graduate Studies Theses and Dissertations 2026

This study addresses the persistent misalignment between the enrollment-based designation of Hispanic-Serving Institutions (HSIs) and the extent to which these institutions implement intentional practices that support Latinx student success. As HSIs continue to grow nationally, it is critical to examine whether institutional efforts move beyond symbolic designation toward meaningful “servingness,” particularly given the increasing reliance on these institutions to advance social mobility and educational attainment for Latinx students. The purpose of this qualitative study is to explore the support structures an HSI provides to promote Latinx student success and to examine Latinx students’ perceptions of the effectiveness of these supports. …

Ex Vivo Sensitivity Assays With Molecular Validation To Guide Preclinical Drug Selection For Schwann Cell Tumors, Ethan W. Hass

Graduate Studies Theses and Dissertations 2026

Schwann cells are the glial cell of the peripheral nervous system. They are dependent on receptor tyrosine kinase-mediated RAS signaling, cell matrix adhesion, and cell-cell contact to proliferate during nerve development and repair. These pathways become deregulated with loss of function of the merlin tumor suppressor encoded by NF2, leading to benign tumors called schwannomas. Patients with NF2-related schwannomatosis (NF2-SWN) develop bilateral vestibular schwannomas that cause hearing loss, tinnitus, and death from brainstem compression if untreated. Severe NF2-SWN causes multiple spinal and peripheral schwannomas and neuropathic pain. Schwannomas require careful monitoring, trial and error use of repurposed anti-cancer …

Strategic Signaling Or Structural Friction?: How Ai Disclosure Moderates Resource-Performance Dynamics In Hotels And Restaurants, Jaewan Heo

Graduate Studies Theses and Dissertations 2026

Artificial intelligence (AI) has become an increasingly important strategic issue in the hospitality industry. While prior research has primarily examined AI as an operational technology that improves efficiency and service delivery, less attention has been paid to how AI-related disclosures influence investor evaluations of firm resources. This dissertation investigates whether AI-related disclosures moderate the relationship between organizational resources and financial performance in publicly traded hospitality firms.

Drawing on signaling theory and the resource-based view, this study conceptualizes AI disclosures as strategic signals that shape investor perceptions of firm capabilities and future value creation. Firm-level financial data were obtained from Compustat …

A Quest For Food In Bedford-Stuyvesant And Brooklyn Heights: Residential Interactions With Neighborhood Food Resources, Aidan Carroll , ‘26

Senior Theses, Projects, and Awards

This thesis examines urban inequalities situated across Brooklyn, New York by speculating residential interactions with food resources in their neighborhood such as gardens, grocery stores, restaurants, and food pantries. With a specific focus on the areas Bedford-Stuyvesant and Brooklyn Heights of Brooklyn, New York, the study utilized qualitative data such as interviews and dietary food logs during ethnographic fieldwork in order to assess the ways in which experiences with accessing food can reveal a deeper message about systemic inequalities along the lines of racism and class if we are to consider food apartheid. That said, I found that food apartheid …
