Aura-Visionpose: Creating Datasets For Vision-Based Pose Estimation, Mohanad Alameer

Masters Theses

"Spacecraft rendezvous is an integral part of many orbital missions, including active space debris removal (ADR) and in-orbit servicing, assembly, and manufacturing (ISAM). Traditionally, rendezvous missions rely mainly on manual ground-based control to perform rendezvous and docking. While this can be effective on an individual basis, it becomes less practical at scale. Autonomous vision-based methods can reduce reliance on human control, and may improve scalability, response time, and reduce the possibility of human error for both ADR and ISAM. This work lays the necessary groundwork for developing a machine learning (ML) model for autonomous rendezvous by creating a labeled image …

Exploring The Temporal Context Of Abusive Supervision, Alexandra Kandah

Graduate Studies Theses and Dissertations 2026

This dissertation examined the temporal dynamics of abusive supervision and their implications for employee burnout and turnover intentions. Drawing from gestalt characteristics theory and uncertainty management theory, this research investigated whether the timing, frequency, variability, and change in abusive supervision influence employee outcomes beyond traditional cross-sectional conceptualizations. Study 1 used a qualitative design to explore how abusive supervision unfolds over time. Fourteen working adults reporting a past abusive supervisor participated in semi-structured interviews focused on the temporal dynamics of their experience with abusive supervision. Results indicated that abusive supervision often began early, recurred frequently, and was characterized by unpredictability and …

Understanding Wage Theft: Beyond The Numbers Through Community Practice, Lived Experience, And Research, André Simões Da Silva, Lenita Reason, Cristina Araujo Brinkerhoff

Gastón Institute Publications

Wage theft is a widespread form of labor exploitation that disproportionately affects immigrant and other vulnerable workers. This report examines the scope and impact of wage theft in Massachusetts by analyzing case data from the Brazilian Worker Center (BWC) alongside wage and labor enforcement data from the Massachusetts Attorney General’s Office (AGO). The analysis demonstrates how wage theft affects immigrant workers across industries, with particularly high numbers of cases in construction, cleaning, and hospitality. The data also reveal significant gaps in the reporting and enforcement of wage violations, particularly among domestic workers, whose cases are likely substantially underrepresented in available …

Exploring The Benefits Of Virtual Learning Environments For Students With Autism Spectrum Disorders, Kenton Louis-Jean

Theses and Dissertations

This qualitative phenomenological applied dissertation explored the lived experiences of K–5 teachers who worked with students with Autism Spectrum Disorder (ASD) in virtual learning environments. As virtual instruction became increasingly prevalent in K–12 education, limited research had examined how teachers adapted instructional practices to meet the cognitive, sensory, and engagement needs of students with ASD in online settings. This study addressed that gap by examining educators' firsthand perspectives on implementing virtual instruction for students with ASD.

Data were collected through semi-structured interviews with eight K–5 teachers who had experience teaching students with ASD in virtual or hybrid learning environments. Participants …

This research aims to bring awareness to the …

1981, Carliss N. Chatman

Faculty Journal Articles and Book Chapters

42 U.S.C. § 1981 should have solved a pervasive problem in American capitalism—when white economic interests do not converge with the contract rights of Black people, they are excluded from the market in a way that causes systemic harm. This Article proposes that the failure to enforce 1981 in the past may render it more harmful than beneficial in the present climate of retrenchment. The realities of racism combine with the lack of economic interest convergence to make combatting contract inequality on a contract-by-contract basis legally precarious, nearly impossible to properly evaluate, and difficult to economically incentivize. This is in …

Facilitating Mortgage Modification To Save Homes And Mitigate Lender Losses, Julia Patterson Forrester Rogers

Faculty Journal Articles and Book Chapters

Homeowners in financial distress or whose homes have been damaged by natural disaster may avoid foreclosure if their lender agrees to modify the loan to reduce payments. Commercial loans may also be modified to avoid foreclosure or in response to changed circumstances or changing market conditions. Although loan modifications are generally beneficial to both borrowers and lenders, barriers to modification exist. The Consumer Financial Protection Bureau (CFPB) has addressed some of the roadblocks to residential loan modifications by regulating the procedures that mortgage servicers must follow in dealing with delinquent borrowers, but the CFPB and its regulations are at risk …

Let’S Modify Safety Valve To Value Family Ties, Laura Ginsberg Abelson

Faculty Journal Articles and Book Chapters

Federal sentencing law has long struggled to balance the breadth of drug conspiracy liability with the prin­ciple of proportional punishment. The statutory “safety valve” provision, codified at 18 U.S.C. § 3553(f) and mirrored in the U.S. Sentencing Guidelines, was designed to provide relief from mandatory minimum sentences for low- level, nonviolent offenders. Yet its requirement that defendants disclose all information concerning the offense sometimes places family-member codefendants in an untenable position: they may avoid harsh penalties only by incriminating loved ones. The requirement also conflicts with other provisions of the Guide­lines that provide guidelines reductions, but not relief from mandatory …

Rethinking Courtroom Presence In The Virtual Era, Jenia Iontcheva Turner

Faculty Journal Articles and Book Chapters

Technological innovation has made virtual appearances by criminal defendants increasingly common. These appearances have advanced efficiency but also raised questions about the scope of both the right and the duty of defendants to be physically present in court. Should judges, for example, be allowed to hold virtual arraignments, even if a defendant wishes to appear in person? Can defendants opt for virtual appearances at will? While courts are beginning to address these questions, they have yet to develop a coherent framework to evaluate when virtual appearances are constitutional and appropriate. This Article seeks to contribute to this project by examining …

Liberty As Entitlement In The Common Law, Joshua C. Tate

Faculty Journal Articles and Book Chapters

In recent decades, some Justices of the U.S. Supreme Court have questioned the broad definition of liberty that is the basis for the doctrine of substantive due process. In his dissenting opinion in Obergefell v. Hodges, for example, Justice Thomas argued that liberty in the common-law tradition “has long been understood as individual freedom from governmental action, not as a right to a particular governmental entitlement.” This Article will argue that such a narrow definition excludes many instances in which the common law used “liberty” as a synonym for “privilege” or “entitlement.” Treatises that were well-known to the Framers …

Digital Assets And The Property Question, Andrea Tosato, Christopher K. Odinet

Faculty Journal Articles and Book Chapters

Is crypto property? The proliferation of digital assets such as cryptocurrencies, stablecoins, meme coins, and non-fungible tokens (NFTs) has confronted legal systems worldwide with three interdependent challenges: determining whether they are property, identifying their appropriate classification within property taxonomies, and establishing rules for their circulation in commerce. Our Article addresses this tripartite question—the “Property Question”—within American law.

The stakes here are significant. Billions of dollars in digital assets are traded daily, used as collateral, and held by custodial platforms. Yet all these transactions rest on an unresolved premise: that digital assets can be owned and are governed by established property …

Survivors Of Historical Intergenerational And Familial Trauma Scale For Black American Descendants Of Enslaved People: A Development And Initial Validation Study, Loryn Chás Kimbrough

Graduate Research Theses & Dissertations

Despite extensive research documenting cultural and racialized trauma, no validated assessment tool had previously captured the intrafamilial mechanisms of trauma transmission specific to the BADEP population, whose trauma lineage is rooted in slavery. The present study addresses this gap through the development and initial validation of the Survivors of Historical Intergenerational and Familial Trauma Scale (SHIFTS), a culturally grounded instrument designed to measure the transmission of historical trauma (HT) and ongoing intergenerational trauma (IGT) among Black American Descendants of Enslaved People (BADEPs). The SHIFTS examines how HT gives rise to the continued transmission of two interrelated legacies: survival-based and trauma-rooted …

Utilizing Coal For Mesophase Pitch-Based Carbon Fiber Production: Precursors, Processes, And Progress, Christina M. Thompson

Theses and Dissertations--Chemistry

Graphitic materials possess unique properties due to the unique combination of layered crystalline structure and carbon’s low atomic weight. High performance carbon fiber is one such example, displaying exceptional strength-to-weight ratios, stiffness, and thermal and chemical resistance. These properties render high performance carbon fiber a critical structural reinforcement material in the manufacture of composites across various industries, such as for automotive and aerospace applications. However, balancing fiber performance with precursor and processing costs remains a challenge. As alternative carbonaceous feedstocks are explored, coal has gained interest for utilization in graphitic products as a relatively abundant and low-cost source of aromatic …

Elucidating The Impacts Of Non-Covalent Interactions In Organic Materials Through A Multiscale Computational Approach, Sashen A. Ruhunage

Theses and Dissertations--Chemistry

Noncovalent interactions (NCIs) in π-conjugated organic materials serve as tunable levers that influence molecular structure and intermolecular interactions in the condensed phase and, in turn, impact the electronic, optical, and mechanical properties of these materials. NCIs include attractive dispersion, electrostatic, and induction interactions, as well as repulsive exchange interactions. However, how to design materials with NCI considerations remains an open question across many fields. Here, we seek to provide an electronic and atomistic perspective on these interactions through multiscale simulations to aid materials design, processing, and performance optimization. In this study, we investigate NCIs and their effects across various systems …

Student Familiarity With The Periodic Table Of The Elements: Results From Cued-Recall And Eye-Tracking Assessments On Memory, Victor A. Okuo

Theses and Dissertations--Chemistry

Learning element symbol–name associations and the spatial organization of elements on the periodic table is a foundational step in learning chemistry, supporting later understanding of chemical formulas, equations, bonding, and stoichiometry. Although students often rely on memorization strategies to learn periodic table content, this task is challenging due to the large number of elements and the apparent ambiguity in matching some element symbols to their names.

This study explores students’ recall of element names when given element symbols as cues and their knowledge of element locations on the periodic table when given element names as cues. The study also examines …

Mouse Models For Post-Sepsis Syndrome, John Matthew K. Ang, Stephanie F. Mori, Erick Lewis, Maria E.C. Bruno, Arnold Stromberg, Hiroshi Saito

Surgery Faculty Publications

Background – Sepsis survivors commonly suffer from chronic Post-Sepsis Syndrome (PSS). To understand the mechanisms of PSS, it is critical to utilize appropriate animal models. While cecal ligation and puncture (CLP) is a widely used model of sepsis, a concern exists regarding its suitability for studying long-term outcomes. Alternatively, we previously optimized a highly reproducible murine cecal slurry (CS)-injection model of sepsis. The objective of this study was to compare the suitability of CS and CLP models for investigating PSS. Methods – Male 4-month-old C57BL/6 mice were divided into 7 groups: (1) Naïve control; (2) Sham: laparotomy control; (3) CL: …

Assessing Sustainable E-Cigarette Prevention Messaging In Public Health Communication, Addo Anim Adinkrah

Graduate Research Theses & Dissertations

This study examines the sustainability of e-cigarette or vaping prevention messaging on X (formerly Twitter) and the message-design strategies used by public health institutions to maintain message visibility over time. Using the McGuire Communication/Persuasion Model and Media Framing theoretical frameworks, the research employs a qualitative thematic analysis based on Braun and Clarke’s six-phase approach to analyze 506 tweets from official accounts affiliated with the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA). The findings reveal that prevention messages are sustained through repeated core warnings and reinforcement of institutional authority rooted in scientific and …

Symbolic Logistic Regression For Interval-Valued Predictors: A Simulation Study And Application To Health Data, Soad Abdullah

Graduate Research Theses & Dissertations

This thesis investigates symbolic logistic regression for interval-valued predictors through simulation studies and a real health data application. Classical logistic regression assumes exact predictor values, whereas in many practical settings variables are available only in interval form due to coarsening or reporting uncertainty. Two simulation studies examine the impact of interval uncertainty under asymmetric intervals and measurement error. Symbolic models based on midpoint and midpoint-plus-width representations are compared with the classical approach. Results show that midpoint modeling captures the general relationship but introduces bias under asymmetry, while incorporating width reduces this distortion. Under measurement error, classical logistic regression exhibits attenuation …

The Only Duck I’Ve Ever Loved Is Daffy In Drag: A Textual Analysis Of Gender Norm Reinforcement In The Looney Tunes Show, Sara Bahaji

Graduate Research Theses & Dissertations

In 2011, Warner Brother’s latest attempt to make Looney Tunes appeal to modern audiences was released, The Looney Tunes Show. This was a departure from classic Looney Tunes, from its slice-of-life sitcom setting to the changes in the characters. But one of the ways it stood out in not just classic Looney Tunes but contemporary cartoons, was its treatment of Daffy Duck. This thesis is a textual analysis of the show’s presentation of Daffy Duck’s gender. Different frameworks were used to build the analytic tools: signifying theory, as presented by Savoy (1995), gender accountability from West & Zimmerman (1987) and …

Identifying Maltreatment Classes And Their Associated Psychological Outcomes From Childhood To Adolescence, Colleen Bartlett

Graduate Research Theses & Dissertations

Previous research has consistently shown that experiencing maltreatment has significant, negative effects on youth’s psychological health; however, research on the psychological impact of maltreatment is often limited by challenges in accurately capturing children’s maltreatment experiences, as most children who are exposed to maltreatment experience multiple types of maltreatment. The present study utilized latent class analyses (LCAs), a person-centered, data-driven approach to empirically identify patterns in children’s maltreatment experiences at ages 3, 5, and 9. Maltreatment class indicators included frequency of behaviorally approximated emotional abuse, physical abuse, and neglect. Following the LCAs, associations between maltreatment class membership and youth internalizing and …

Plant Practices And Community At The Heart Of Hopewell: Paleoethnobotany At The Overly Site And Beyond, Abigail Deewaard

Graduate Research Theses & Dissertations

Paleoethnobotanical analyses of Ohio Hopewell habitation sites in past decades have shed light on the subsistence practices, settlement patterns, and environmental management of Indigenous peoples engaged in what archaeologists describe as the Hopewell phenomenon. However, comparatively less attention has been paid to the social dimensions of plant use, particularly at habitation sites in the Scioto Hopewell region. Hopewell is an archaeological term that refers to the Middle Woodland (ca. 100 BCE–400 CE) network of interregional relationships across eastern North America characterized by long-distance exchange, monumental earthwork construction, and ceremonial practices including the honoring of ancestors. This thesis applies a social …

New Methods For Bright Electron Beam Generation At The Argonne Wakefield Accelerator Facility, Emily Frame

Graduate Research Theses & Dissertations

Bright electron beams generated via photoinjectors have enabled many recent developments in accelerator technology, including x-ray free electron lasers and ultrafast electron microscopy and diffraction systems. The conceptual design, scientific reach, and accessibility of these and next-generation accelerator applications can be significantly improved by increasing electron beam brightness. Therefore, the development of novel methods to further enhance beam brightness remains a critical priority in the field.

One of the primary factors limiting beam brightness is the mean transverse energy (MTE) of photoemitted electrons. The MTE is an intrinsic property of the photocathode and is proportional to the square of the …

4d-Qens And Diffuse Scattering: Analysis Of Dynamics And Local Ordering In Superionic Conductors, Jared Coles

Graduate Research Theses & Dissertations

Ionic conductors are increasingly central to electrochemical energy technologies because they enable charge transfer through the motion of mobile ions. Among them, superionic conductors are crystalline solids that exhibit exceptionally high ionic conductivities, making them promising candidates for safer and more sustainable next‑generation energy storage and conversion devices. Despite their technological importance, key gaps remain in our ability to connect macroscopic transport to microscopic structural disorder and correlated dynamics that enable fast‑ion motion. Neutron scattering provides a powerful set of tools for establishing these connections.

In total scattering experiments, Bragg diffraction measures the average crystallographic structure, while diffuse scattering probes …

Longitudinal Dechirping Of Electron Beams Using Negative Identity Drifts In A Transverse Deflecting Cavity-Based Chirper, Alex Desimone

Graduate Research Theses & Dissertations

Electron beam chirping for bunch compression is commonly achieved through off-crest acceleration in radio-frequency accelerating cavities. While it is effective, this method reduces average beam energy and introduces nonlinearities in the beam's longitudinal phase space, which can degrade beam quality in applications such as X-ray free electron lasers. An alternative chirping scheme has been proposed, in which accelerating cavities operate on-crest while transverse deflecting cavities generate the required longitudinal chirp. However, the efficiency of this approach and its impact on beam quality have not been systematically investigated, and the previously proposed dechirping scheme for this system is experimentally impractical. This …

Application Of Paper Spray Mass Spectrometry For Screening Acetylcholinesterase Inhibitors, Diksha Gautam

Graduate Research Theses & Dissertations

Paper spray mass spectrometry (PS-MS) is a novel ambient ionization method that allows chemical and biological samples to be rapidly analyzed with little preparation being required. In this paper, PS-MS was set up and streamlined as an acetylcholinesterase (AChE)-monitoring platform in addition to screening an existing and newly produced AChE-inhibitors. The detection of the substrate, acetylcholine (m/z 146), and the AChE catalysis product, choline (m/z 104) was performed without applying chromatographic separation or derivatization to the dried paper substrates. Assay conditions were optimized in a systematic way, to develop a robust MS-compatible enzymatic workflow.

Calibration curves for both, acetylcholine and …

On Values Taken By Characters Of Finite Groups, Christopher William Herbig

Graduate Research Theses & Dissertations

The characters of finite groups are a fundamental tool for analyzing the structure of finite groups and are interesting in their own right. In particular, we are concerned with how certain assumptions on the values taken by characters impact the structure of finite groups and vice versa. After establishing notation and stating some fundamental results in Chapter 2, this work begins with a presentation of results in relation to a conjecture of N. N. Hung and P. H. Tiep on fields generated by character values. In particular, we have found a large family of counterexamples to the conjecture by taking …

Self-Movement Cue Ability As A Potential Moderator For The Relationship Between Binge Drinking And Posttraumatic Stress Disorder Symptoms, Dominoe Anna Jones

Graduate Research Theses & Dissertations

Alcohol use disorder (AUD) has been found to co-occur in a range of 30% to 50% of individuals diagnosed with posttraumatic stress disorder PTSD. The current study aimed to assess whether this high comorbidity could be partially explained through a shared association with poorer function and reduced volume in the hippocampus. Self-movement cue processing, a behavioral ability previously shown to be associated with hippocampal functioning, was measured through a dead reckoning task (DRT) to test this hypothesis. The current study failed to replicate previous findings between alcohol use and DRT and alcohol use and posttraumatic stress symptoms (PTSS). Performance on …

Bayesian Inference For A 12-Level Galton Board Using Terminal Bin Counts, Ace Frieders

Graduate Research Theses & Dissertations

A Galton board is a physical device in which a ball passes through a triangular array of pegs and is deflected left or right before landing in one of several bins. Under an idealized model, deflections are independent with probability 0.5 of moving right, implying a binomial distribution for the terminal bin location. Physical boards may deviate from this ideal due to asymmetries and other sources of bias. This thesis develops a Bayesian model for a 12-level Galton board in which each peg has its own right-move probability. Independent Beta priors are assigned to peg probabilities, and terminal bin counts …

Hallucination Detection In Scientific Writing: Quantification, Trend Analysis And Benchmarking, Adiba Ibnat Hossain

Graduate Research Theses & Dissertations

The landscape of scientific communication has undergone a significant transformation with the emergence and widespread adoption of Large Language Models (LLMs). LLMs have enhanced productivity and creativity in scientific writing, raising serious questions about the faithfulness and reliability of the generated content. A common problem in LLMs is hallucination, which occurs when models generate fluent but inaccurate or inconsistent content. When hallucinations enter scientific writing, the intended meaning may be distorted, coherence disrupted, and the study’s overall integrity threatened.

This thesis investigates hallucinations in scientific writing from both an analytical and dataset-driven approach. First, it offers a comprehensive analysis of …

A Multi-Study Examination Of Student-Athlete Mental Health And Mental Health Service Delivery In Mid-Major College Athletic Programs, Grace Louis

Graduate Research Theses & Dissertations

Student-athlete mental health has become a central priority in intercollegiate athletics, with the NCAA emphasizing its Mental Health Best Practices (2016) and strengthening and expanding these standards through updated recommendations in 2024. These efforts reflect a broader cultural shift toward recognizing the unique psychological stressors faced by college athletes, including performance pressure, identity foreclosure, high time demands, and transitions both into and out of sport (Moreland et al., 2018; Hughes & Leavey, 2012). Additionally, student-athletes frequently delay or avoid help-seeking due to stigma, time constraints, identity-protective behaviors, cultural norms emphasizing toughness, and limited mental health literacy (Gulliver et al., 2012; …
