Well-Being, Resilience, And Trauma During Migration: A Mixed Methods Study Of Venezuelan Migrants In Transit, Margaret S. Port

Dissertations

A substantial body of research has examined the psychological impact of experiences preceding and following migration, yet comparatively little attention has been given to the psychological toll of the migration journey itself. Moreover, due to the relative novelty of the Venezuelan migrant crisis and the community’s arrival in the United States, the psychological impact of Venezuelan migrants’ unique migration experience has been underexamined. This study utilized an explanatory sequential mixed methods design to investigate the relationships between well-being, resilience, and trauma among Venezuelan migrants in Chicago, Illinois, while also exploring their lived experiences of the migration journey. Study participants (n …

Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires

Dissertations

Military service members are shaped and molded to fit a military culture that emphasizes mission readiness and continuous preparedness. Countless hours are spent training for various situations that can arise. Many trainings are geared toward worst-case scenarios that can cause an increase in stressors and traumatic events. They are expected to demonstrate resilience and overcome adversity to remain mission-ready. This expectation to be mission-ready creates the space for mental health difficulties as well as stigma and avoidance of help-seeking behaviors. In many cases, the desire to stay mission-ready creates a barrier for conversations around mental health. The military emphasizes qualities …

Findings across the literature indicate that both cognitive behavioral …

The Motherhood Contract: Mental Load, Moral Risk, And Gendered Care In Contemporary Parenting And Digital Culture, Stephanie J. Stallman

Dissertations

This dissertation examines childcare as a site of gender inequality shaped by cultural norms, structural barriers, and digital discourse. Despite increased awareness of shared parenting ideals, mothers predominantly bear the “mental load.” This study introduces the idea of a motherhood contract: implicit expectations that mothers are responsible for managing children’s needs. Two research questions guide this study. (1) What are parents’ experiences of managing the mental load of caregiving? How do they make sense of these experiences within the gendered and moral expectations shaping family life? (2) How are cultural ideas about childcare and parenting constructed, circulated, and reproduced through …

Diverse Families Navigating Mental Health At The Pediatrician’S Office: A Mixed Methods Exploration Of The Interplay Of Stress, Culture, And Child Mental Health In The Primary Care Setting, Sara B. Budowsky

Dissertations

Low-income and ethnic minority youth experience high psychiatric need but persistently low participation in traditional mental health care. General pediatricians are often the first and only healthcare providers with whom many families engage around their child’s emotional and behavioral development. Using both quantitative analysis of retrospective secondary data and Interpretative Phenomenological Analysis (IPA) of in-depth interviews with diverse caregivers, this project explored influencers of child mental health and family utilization of pediatric primary-care-based mental health services in the context of a uniquely multicultural clinic serving a predominantly Medicaid population. Three key findings include: 1) Caregiver Stress was a highly significant, …

Leadership Without Assimilation: Reimagining Executive Leadership Development To Affirm Black Identity And Leadership Persistence, Nicole Monroe

Dissertations

Executive leadership development programs are often treated as race-neutral pathways to advancement, yet they frequently reflect dominant cultural norms that require leaders from marginalized communities to assimilate in order to succeed. This study examined the question: How can executive leadership development be restructured to affirm Black identity, cultural intelligence, and leadership persistence rather than require assimilation into exclusionary models? This study employs a convergent mixed-methods design, including interviews with 9 Black executive leaders and a document analysis of leadership development programs using the Assimilation Pressure Index. Findings reveal persistent assimilation pressures and identity negotiation within leadership development experiences, and document …

Fairness, Representation, And Retrievability In Ai Information Systems, Xiaoxiao Shang

Engineering Ph.D. Theses

Artificial intelligence and machine learning systems are deeply embedded in modern information ecosystems, yet the bias they exhibit is not a single phenomenon. This dissertation identifies three distinct stages of the AI pipeline at which bias surfaces, each demanding a di!erent conceptual treatment: measurement bias in preprocessing, addressed through identification fairness; content bias at the corpus level, addressed through representation equity; and systemic bias in retrieval, addressed through distributional justice. Measurement bias arises when raw signals about people are converted into categorical labels, and errors at this stage propagate into every subsequent computation. In race and ethnicity prediction from names, …

Essays On Health And Immigration Policy, Selen Ozdogan

Dissertations, Theses, and Capstone Projects

This dissertation consists of two essays in applied microeconomics, each examining how individuals and institutions respond to policy changes. Both essays leverage natural experiments and recent advances in difference-in-differences estimation to identify causal effects. Both also speak to a common theme in public policy: the gap between intended and actual consequences of government intervention, and the role that policy design plays in shaping those consequences.

The first essay examines the impact of state-level e-cigarette excise taxes on nicotine and tobacco exposure among adults aged 18 and older. A central contribution is its use of individual-level panel biomarker data from urine …

Effects Of Overcorrection On Mitigating Uncontrolled Tipping During Incisor Retraction Using Clear Aligners: Finite Element Analysis And In Vitro Experiment, Jianing Wang, Niko Burger, Bo Wang, Linxia Gu, Pengfei Dong

Biomedical Engineering Faculty Research and Publications

Uncontrolled tipping during incisor retraction with clear aligners continues to limit orthodontic treatment. Different countermeasures have been proposed to improve the predictability of aligners, such as power ridges and attachments, while their efficacy requires further investigation. This work investigated the biomechanics of the overcorrection in reducing the tipping angle and moment during incisor retraction with a clear aligner, through in vitro experiments and finite element analysis (FEA). Specifically, the influence of overcorrection angle (1 deg), retraction distance (0.15 mm), and the combination of both were assessed through in vitro experiments and the finite element simulation. Further computational simulations were conducted …

Parkinson’S Disease Phenotype Stratification Using Multiple Correspondence Analysis, Kelly Astudillo

Dissertations, Theses, and Capstone Projects

Parkinson’s disease (PD) is the second most common neurodegenerative disorder, with over 12 million people projected to be affected by 2040 (Dorsey et al., 2018). Deep phenotyping and stratification can provide useful information regarding PD pathogenesis and can aid in the  development of disease modifying therapies that aim to delay the progression or prevent the onset of neurodegeneration (Blandini et al., 2019; Smith & Schapira, 2022). Utilizing multivariate methods such as multiple correspondence analysis (MCA) permits for the simultaneous analysis of distinct data modalities. To the best of our knowledge, MCA has not been previously used to explore phenotype patterns …

Gathering Knowledge, Sustaining Science: The Female Forager And American Mushroom Culture, 1880–1930, Madeline S. Dede-Panken

Dissertations, Theses, and Capstone Projects

Unearthing origins of modern mycophilia, this dissertation explores the mushroom mania which reverberated through American society at the turn of the twentieth century, empowering Anglo-American women in new ways. America’s largely forgotten first mushroom fad illuminates gendered negotiations of foraging culture and public science. Beginning in the 1880s, a remarkable cohort of women helped turn mushrooms from shunned, mysterious organisms into wholesome delicacies for culinary and intellectual enrichment. Female enthusiasts fostered a vibrant mushroom culture and nationwide network of mycophiles. Culinary applications and poisoning fears legitimized women’s presence in scientific endeavors, positioning mycology as vital female knowledge for public safety …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …

Policing Sex Trafficking: 'They’Re Never Taught, You Know', Anila S. Duro

Dissertations, Theses, and Capstone Projects

Research shows that victims of sex trafficking are most likely to first come in contact with the police (Baldwin et al, 2011; Twigg, 2017) and at times police have not been able to categorize cases of prostitution as trafficking even when trafficking elements were very clear (Dank et al, 2017; Dempsey, 2017; Farrell & Cronin, 2015). Despite the legal definition of trafficking, the terms prostitution, sex work, and sex trafficking are sometimes used interchangeably by law enforcement, whereas at other times, these words refer to different sets of circumstances and have different criminalization outcomes.  Research in this area is limited …

Investigating Individual And Group Level Mediators Of Fear Acquisition, Rachel S. Lese

Dissertations, Theses, and Capstone Projects

The ability to discriminate between cues predictive of threat vs. safety (fear acquisition) and subsequently update fear responding when contingencies change (fear extinction) is crucial to survival for all organisms. While these processes have been the subject of intense experimental scrutiny for several decades, most human fear learning studies have focused primarily on extinction learning and fear recovery processes, with less focus on fear acquisition itself. Indeed, researchers typically aim to minimize variability during fear acquisition in order to rule out differences in extinction being driven by variability during the initial learning phase. Thus, experimental protocols are often optimized to …

Cooling Deserts For Renters: Heat Equity Inside The Nyc Housing System, Tahreem Ashraf

Dissertations, Theses, and Capstone Projects

This study introduces the Cooling Desert Index (CDI), a composite spatial measure designed to identify census tracts in New York City where extreme heat vulnerability and structural barriers to adaptive cooling converge. Drawing on five publicly available datasets and a seven phase statistical pipeline, the CDI scores all 2,231 NYC census tracts on a continuous 0 to 100 scale by integrating heat exposure, severe rent burden, household income, racial composition, language access, disability status, and housing crowding. The analysis identifies 557 cooling deserts, defined as tracts where environmental heat risk is high and financial constraints make effective cooling structurally inaccessible, …

Vestigial Choreographies: Climate Consciousness In The Long Nineteenth Century, Alexandra A. Rego

Dissertations, Theses, and Capstone Projects

The aims of this project are twofold: (a) to develop a method of theoretical analysis and (b) to put this method into pointed use. In service of (a), I propose a method of choreographic analysis. This method operates relationally, highlighting the production of movement and stillness among and between bodies, objects, and encounters. Choreographic analysis draws from methods typically sequestered to dance studies. Towards aim (b), this project demonstrates the relevance and breadth of choreographic analysis by connecting it to ecocriticism. Throughout this project, I apply choreographic analysis to a diverse set of case studies. I use choreographic analysis to …

Roe V. Wade With Audre And Nikki: Their Social And Political Impacts Following The Landmark Decision, Sharon L. Eaddy

Dissertations, Theses, and Capstone Projects

This thesis analyzes how the 1973 Supreme Court decision Roe v. Wade shaped public understandings of reproductive rights and how those understandings diverged across race, gender, class, and sexuality. Using a qualitative, interdisciplinary design, the study pairs close textual analysis of Nikki Giovanni’s and Audre Lorde’s poems and essays with socio-legal and historical context on constitutional privacy doctrine, the Ninth and Fourteenth Amendments, and the Reconstruction legacy of the Civil Rights Act of 1866. The central research question is: what kinds of reproductive “freedom” become legible through Roe’s rights-based framing, and what forms of constraint remain visible when Black …

Building On Rented Land: An Interpretive Phenomenological Analysis Of Black Women’S Digital Homeplace-Building On Tiktok, Monica Thompson

Dissertations, Theses, and Capstone Projects

This interpretative phenomenological analysis (IPA) examined the lived experiences of seven Black women TikTok users, exploring how they describe and make meaning of TikTok as a space of digital expression amid algorithmic constraint and platform precarity. Grounded in Black Cyberfeminism, Critical Race Theory, and hooks’ (1990) homeplace theory, the study asked three questions: how Black women describe their use of TikTok; how they make meaning of the platform as a space of expression; and how they navigate platform instability, political threats, and content restrictions while maintaining authentic expression. Drawing on semi-structured Zoom interviews and analyzed using Smith et al.’s (2009) …

Bureaucracy, Bottlenecks, And Bots: Ai And Migrant Experiences At Germany’S Foreigners’ Authorities, Johanna Brusa

Dissertations, Theses, and Capstone Projects

How can AI provide a meaningful tool in migration management for the German government? Seeking highly-skilled migrants and overburdened by mass migration, the German government is turning to AI to generate solutions to bureaucratic overload in the Ausländerbehörden (ABH, the Foreigners’ Authorities), the Federal Republic's administrative system for managing the processing of migration. AI promises to ease the bureaucratic burden on civil servants, but can it improve migrants' experiences in their interactions with the ABH? And, critically for the German state, could it help convince highly-skilled workers to make Germany their home? Analyzing 530 Google reviews of six different ABH …

Aphrodite In Movement And Miniature: Knidian Statuettes Of The Ancient And Modern, Jacqueline M. Lewis

Dissertations, Theses, and Capstone Projects

This thesis examines Hellenistic statuettes of the Knidian Aphrodite as independent works of art with distinct ancient contexts and modern collecting histories. Drawing on archaeological evidence from Delos, archival and public records from the Museum of Fine Arts, Boston, and the Metropolitan Museum of Art, New York, and a comparative framework that places Hellenistic and modern collecting cultures in dialogue, this thesis aims to present the Knidia within the dynamic, interactive history of statuettes. Evaluated on its own terms rather than in relation to a lost original, Knidian Aphrodite statuettes illuminate both the richness of Hellenistic domestic religious life and …

Reimagining Puerto Rican Sonic Identity: Musical Style And Creation After Hurricane María., Gabriel E. Bouche Caro

Dissertations, Theses, and Capstone Projects

This dissertation examines the manifestation of Puertorriqueñidad (Puerto Rican identity) in concert music composed after Hurricane María (2017), a catastrophe that catalyzed a profound shift in Puerto Rico's cultural consciousness. Focusing on four composers whose early careers were shaped by this period—Johanny Navarro, John Rivera Pico, Iván E. Rodríguez, and Christian Quiñones—the study combines close readings of scores and recordings with extensive original interviews to understand how musical identity is constructed in the wake of collective trauma. The analysis reveals that while the composers share a generational bond, their aesthetic practices are strikingly diverse: Navarro preserves Afro-Caribbean rhythmic structures, Rivera …

It addresses how Latine clinical social workers, who incorporate ancestral wisdom in their practice determine when, with which clients and with which methods to do so. This work advances current scholarship on how clinical social workers can combat racism and white supremacy. It highlights resistance practices that have been critical in keeping people indigenous to colonized lands alive and …

Who Is Invited To The National Family? A Brazilian Autoethnography Of Being A Woman Under The U.S. O-3 Visa, Bruna Lauermann

Dissertations, Theses, and Capstone Projects

This thesis lives in the borderlands between Brazil and the United States, during the nine years of my immigration to the United States. Using autoethnography, I analyze the O-3 visa as a tool that controls and alienates foreign women and devalues knowledge produced outside U.S. borders. This visa, for spouse or children of O-1 holders, which are people considered to have extraordinary abilities to work in the U.S. showcases the reasons why one is invited to be part of the national family and under what obligations and circumstances. A decision that is shaped far more by the interests of the …

Exploring The Influence Of Ear-Level Devices On Adult Perceptions Across Professional, Social, And Educational Settings, Lucia R. Berry

Dissertations, Theses, and Capstone Projects

Background: The hearing aid market is continuously advancing to address the increasing prevalence of hearing loss and the barriers to obtaining hearing aids. The Food and Drug Administration (FDA) approved Apple AirPods Pro 2 devices to function as over-the-counter (OTC) hearing aids. This is an alternative option to manage hearing difficulties; however, it presents secondary complications related to headphone use and stigma.

Objective: Limited research is available regarding attitudes towards individuals wearing Apple AirPods Pro 2 as OTC hearing aids. This study intended to analyze if people’s pre-established perceptions of Apple AirPods shift once they learn they are being used …

Computational Insights Into Nucleosome Dynamics In Epigenetics Using Molecular Dynamics Simulations, Rutika Patel

Dissertations, Theses, and Capstone Projects

Nucleosome core particles (NCP) are the building blocks that form a highly organized and compact chromatin structure. Nucleosomes package DNA in the nucleus of eukaryotic cells. The NCP consists of about 147 base pairs of DNA wrapped around the histone octamer, with 1.65 superhelical turns in a left-handed manner. The histone octamer is composed of two copies of H3, H4, H2A, and H2B. Together with histone H1 and linker DNA, they further assemble into a higher-order chromatin structure. The nucleosome complex is stabilized by electrostatic interactions between positively charged histone residues and the negatively charged DNA backbone. To effectively access …

Enhancing Ecological Validity In Speech-In-Noise Testing: Integrating Virtual Reality For A Multisensory Audiological Experience, Paulina Lee

Dissertations, Theses, and Capstone Projects

Despite the remarkable advances in hearing healthcare technology, the speech recognition tests used in routine clinical audiological assessment have remained essentially the same for decades.  Monosyllabic word recognition tests in quiet, such as the Northwestern University Auditory Test No. 6 (NU-6; Tillman & Carhart, 1966), have served as the audiology field’s default measure of speech understanding.  Modern speech-in-noise (SIN) tests, such as the QuickSIN (Killion et al., 2004), have emerged, yet they remain auditory-only, leaving an unignorable gap between what clinical tests measure and how patients communicate in daily life.  The present study examined whether pairing a standard SIN test …

Reducing The Complexity Of The Experimental Design Attenuates Trait-Level Effects In Threat Safety Discrimination Learning, Justin M. Lazzarino

Dissertations, Theses, and Capstone Projects

Trait measures of negative emotionality have sometimes been shown to play a role in shaping threat learning, but findings are mixed. For example, Johnson et al (2023) showed that the inhibitory and prospective subscales of the Intolerance for Uncertainty Scale (IUS) were associated with diminished and enhanced threat-safety discrimination, respectively, during the acquisition phase of a Pavlovian fear conditioning task. This finding was subsequently replicated in an independent sample (Kinney-Petrucha, 2024, unpublished). However, these findings and other trait-level fear acquisition effects have not been consistently observed in the broader fear learning literature. Variation in the complexity of or uncertainty inherent …

The History Of The Constitution Is Our Future., Maggie Blackhawk

Michigan Law Review

The Constitution of the United States establishes a government; it also stands as the fundamental law of a people. It shapes daily life, distributes power, and sets a direction for the future. And yet when we ask about the reach and meaning of the Constitution, we are increasingly told to look backward. The answers to our future are said to lie in the past.
