Exploring Engineering Technology: A Multi-Year, Multidisciplinary Project-Based Engineering Technology Workshop, Benito Mendoza, Angran Xiao, Muhammad Ummy

Publications and Research

Many students enter engineering technology programs with a limited understanding of disciplinary differences, curricular expectations, and career pathways, contributing to early dissatisfaction and attrition. To address this challenge, we developed Exploring Engineering Technology, a multidisciplinary, project-based workshop that introduces students to Mechanical, Electrical, and Computer Engineering Technology through a shared robotic systems project. This paper presents a multi-year design-based educational research (DBER) study documenting the iterative refinement and sustained implementation of the workshop across three consecutive summers (2023–2025) at a large urban public college. Using a consistent post-workshop survey administered across cohorts and aggregate student progression indicators, we examine …

Structure Functions For The Inclusive Semileptonic B-Quark Decay At Nnlo: A Semi-Analytic Calculation, A. Broggio, B. Capdevila, A. Ferroglia, P. Gambino

Publications and Research

We present a study of the inclusive charmless semileptonic b decay, b → X_uℓv at next-to-next-to-leading order (NNLO) in perturbative QCD, with the primary aim of extracting the hadronic structure functions Wi at NNLO. The analysis is based on a numerical calculation of the relevant kinematic distributions using a phase-space slicing method to handle infrared-sensitive contributions from real gluon emissions. We use known results from Heavy Quark Effective Theory and Soft-Collinear Effective Theory to extract the singular terms and construct a model for the regular contributions to the structure functions at NNLO, then perform a fit to the …

Tourian, Marzi Azarderakhsh, Rovshan Abbasov, Ali Mehran, Ali Torabi Haghighi, Stefanos Xenarios, Azara Boschee, Salih Babagiray, Mojtaba Sadegh, Nima Shokri, Ali Nazemi, Alireza Farahmand, Samaneh Ashraf, Temur Khujanazarov, Elmira Hassanzadeh, Dalal Najib, Daniel Placht, Shamshagul Mashtayeva, Ekaterina Rets, Hamid Norouzi, Kaveh Madani, Manoochehr Shirzaei, Hossein Shafizadeh-Moghadam, Chiyuan Miao, Ali Mirchi, Shuo Wang, Amir Aghakouchak

Publications and Research

The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood. Here, we integrate satellite observations, in situ hydrological records and reanalysis data to examine recent drivers of the Caspian water loss. We show that total river inflow to the Caspian Sea has declined significantly, primarily due to reduced discharge from the Volga River. At the same time, precipitation over the basin has remained broadly stable, while …

Enhancing Digital Literacy Programmes For Advanced Search Skills Of Adult Public Library Patrons, Santel Smit Ms., Nikiwe G. Momoti Dr

Urban Library Journal

Digital literacy enables individuals to confidently engage with electronic devices and digital resources. While many adults use these tools to search for information, some still lack the essential skills to do so effectively. This pragmatic paper investigates the basic digital literacy skills of adult patrons at Adriaanse Public Library in Cape Town. Framed by SCONUL Seven Pillars of Information Literacy through a Digital Literacy “lens”, we employed a sequential mixed-methods approach, combining quantitative pre- and post-tests with qualitative interviews among 30 purposively selected participants. Quantitative data was analyzed statistically while thematic analysis was used for qualitative data. The findings revealed …

Bullying, Early Sexual Debut, And Sexual Health Behaviors Among Adolescents In New York City, Valentina I. Ramirez

Dissertations and Theses

Adolescent sexual and reproductive health remains a critical public health priority in the United States, particularly given the persistent burden of HIV and sexually transmitted infections (STIs) among young people. Adolescents and young adults account for a disproportionate share of STI cases, reflecting ongoing gaps in prevention, early detection, treatment, and equitable access to sexual health care and services. These patterns are shaped not only by individual behaviors but also by broader social, structural, and developmental contexts that influence adolescents’ opportunities to engage in preventive sexual health care.

This dissertation examined associations between early sexual debut, experiences of bullying, and …

Advance Care Planning In Metastatic Lung Cancer Patients: A Quality Improvement Initiative, Khanh H. Thai

Student Theses

Background: Advance care planning (ACP) is essential in achieving goal-concordant care for patients with metastatic lung cancer (MLC), yet it remains underutilized.

Local problem: Despite its benefits, ACP has been inconsistently integrated into outpatient oncology settings, and a baseline evaluation at the project site revealed that only 11% of patients with MLC had ACP documented in the outpatient care clinic.

Methods: This Quality Improvement initiative implemented a formal, Nurse Practitioner (NP)-led intervention into routine oncology care. Using a quasi-experimental nonrandomized design, 13 eligible patients diagnosed with MLC without prior ACP documentation were enrolled in a four-week study. These participants were …

Centering Well-Being And Wholeness: Exploring Racial Battle Fatigue Among Black 3-K To Twelfth-Grade Teachers, Olubunmi Fashusi

Theses and Dissertations

This qualitative case study, with some descriptive statistics, examined Black 3-K through 12th- grade teachers’ experiences with racial battle fatigue (RBF), the psychological and behavioral stress responses they perceived most accurately convey how RBF manifests for them, and the strategies they used to disrupt RBF’s impact. Participants experienced compounded RBF due to advocating for students (i.e., speaking out, supporting, or intervening). Participants’ most perceived psychological stress response to RBF was racism awareness, and most perceived behavioral stress response was spirituality or religion. Participants disrupted the impact of RBF through intrinsic care (i.e., purpose or why, managing emotions, and self-care) and …

Socioeconomic Inequalities In Health-Related Quality Of Life During The Covid-19 Pandemic: A Six-Country Comparison Using The Eq-5d-5 L, Joëlle Eijkens, Joshua M. Bonsel, You-Shan Feng, M. F. Bas Janssen, Erica I. Lubetkin, Juanita A. Haagsma

Publications and Research

Purpose

Despite the growing attention to health inequalities, there is no global consensus on how to measure socio-economic status. This study examined inequalities in health-related quality of life (HRQoL) during the early phase of the COVID-19 pandemic across six countries—China, Italy, the Netherlands, Sweden, the United Kingdom (UK), and the United States (US)—using three SES indicators: education level, income, and work status.

Methods

Between April and June 2020, individuals aged 18–75 years old completed a web-based survey. HRQoL was measured using the EQ-5D-5L Level Sum Score (LSS), where higher scores indicate poorer health. Country-specific differences in LSS across SES groups …

Investigating Potential Bias In Public Acceptance Of Restorative Justice: The Influence Of Situational And Offender Characteristics, Kiara Haynes

Student Theses

Restorative Justice has been an emerging justice mechanism in the U.S. since the 1970s that advocates are working to expand more widely throughout the justice system. Due to victims and the broader community of the offender being an integral part of the Restorative Justice process, it is critical to consider the general public's support of this novel justice mechanism, as well as the influence that social biases among the public may have on the experience of defendants going through the system. The study conducted examined the effect that social biases toward an offender's personal characteristics have on attitudes and opinions …

Forensic Analysis Of Temporary Tattoo Markers And Inks, Daniel J. G. Chasse Jr

Student Theses

As tattoos rise in popularity, some marker manufacturers have created temporary tattoo markers so that children and adults can experience tattoos without the permanence of a regular tattoo. These new products are marketed explicitly as ‘temporary tattoo markers’ and intended for direct application to the skin. This research aims to scientifically evaluate the inks from these temporary tattoo markers to elucidate their physical and chemical properties using wet chemistry, visual examination, ultraviolet-visible spectroscopy (UV/Vis), Fourier-transform infrared spectroscopy (FT-IR), attenuated total reflectance infrared spectroscopy (ATR-IR), thin layer chromatography (TLC), and diffuse reflectance infrared spectroscopy (DRIFTS) to analyze temporary tattoo markers and …

Adversarial Robustness Of Perceptual Hashing Systems: A Unified Security Evaluation Framework, Avijit Roy

Student Theses

Social network platforms, child safety organizations, and image provenance systems use perceptual hashing to identify known child sexual abuse material (CSAM), support content moderation and reverse image search, and verify image integrity. Perceptual hashing works by producing similar fingerprints for visually similar images, even after common transformations such as compression, resizing, or minor brightness changes. This useful similarity-preserving property also creates an adversarial attack surface, as attackers can use AI-assisted or conventional image manipulation techniques to move a hash across a matching threshold while maintaining visual similarity, often without access to specialized hardware.

The security failures produced by adversarial attacks …

The Security Of Llm-Generated Code, Christopher Brian Gonzalez Ayala

Student Theses

The rapid adoption of Large Language Models (LLMs) in software development has transformed coding practices by enabling automated code generation, completion, and optimization. Despite these advantages, concerns persist regarding the security and reliability of LLM-generated code. This study presents a comprehensive evaluation of both the functional correctness and security of code produced by three prominent LLMs as of early 2026. A total of 4,800 code snippets were generated using 100 security-focused programming prompts derived from the OWASP Top 10:2025, translated across eight natural languages and two phrasing styles (literal and natural developer-oriented prompts). To assess performance, a multi-stage experimental framework …

The Comparative Chemical Analysis Of Colored Henna, Vani D. Bhagwandeen

Student Theses

Henna, a natural dye derived from Lawsonia inermis, is widely used for temporary body art, hair coloring, and cultural decorative practices such as Mehendi. Traditional henna produces a reddish-brown stain through lawsone, a naphthoquinone chromophore that binds to keratin in skin, hair, and nails (Badoni Semwal et al., 2014; de Groot, 2013; Kumar Singh et al., 2015). Commercial henna products have increasingly incorporated synthetic dyes, pigments, and glitter additives to produce a broader range of colors and effects (Blair et al., 2004; Manso et al., 2017; Blackledge & Jones, 2007). Despite their prevalence, limited forensic research has examined the …

Investigating The Detection Ability Of Presumptive Bloodstain Testing Through Concealment Obstacles, Skye E. Lehr

Student Theses

Bloodstain detection can provide valuable information on the ability of presumptive tests. When perpetrators seek to alter the scene of violent crimes to interfere with investigations or flee from justice, crime scene investigation becomes more complex. In this analysis, scenarios where bloodstain evidence is attempted to be removed by household cleaners and covered up by acrylic or oil-based paint, are tested using luminol and Kastle-Meyer direct testing. These bloodstains have been altered by bleach, dish soap or all-purpose cleaner and covered under multiple layers of acrylic or oil-based paint. Evidence is documented both photographically and visually to simulate crime scene …

Radiotheranostics For Gynecological Pathologies, Joni Sebastiano

Dissertations, Theses, and Capstone Projects

Molecular imaging, specifically positron emission tomography (PET), is vital for detecting disease and understanding its biological makeup. The exploitation of radiolabeled antibodies for PET imaging has proven to be indispensable to the field of molecular imaging over the last several decades. The development of radioimmunoconjugates for use in immunoPET has not only allowed for the sensitive, specific, and high-resolution detection of disease, but has also enabled a deeper understanding of the disease biology, ultimately guiding more personalized therapeutic strategies. Most typically, this technology is harnessed for the diagnosis and treatment of cancer, however more recently, the field has explored the …

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 …

Quiver Of Affine Monoid Of A Vector Space Over Finite Field, James Junie Chen Cleary

Dissertations, Theses, and Capstone Projects

In this paper, we study the quiver of the complex monoid algebra CAFF(n, q). There are n + 1 maximal subgroups of AFF(n, q), each isomorphic to AGL(k, q) for some 0 ≤ k ≤ n. Every irreducible representation of CAFF(n, q) arises from a character of CAGL(k, q) for a suitable k. Thus, we study two different approaches to classifying the characters of CAGL(k, q). Next, we compute the full quiver Q(CAFF(n, q)). Finally, we show that this quiver is a disjoint union of straight-line paths and that its basic algebra has radical square zero. Hence, it has finite …

Music Appreciation In Cochlear Implant Users: A Questionnaire, Hanna Davidson

Dissertations, Theses, and Capstone Projects

Cochlear implants provide significant benefits for speech perception in individuals with severe to profound hearing loss; however, music perception and appreciation remain challenging due to limited spectral and temporal resolution. This study examined music appreciation in post lingually deafened adult cochlear implant users, focusing on changes in enjoyment, listening behaviors, and subjective experiences following implantation. Sixteen adults completed a 36-item questionnaire assessing pre- and post-implant music engagement, perceived sound quality, and emotional responses to music. Quantitative data were analyzed using descriptive statistics and inferential statistics, and qualitative responses were analyzed thematically.

Results indicated a moderate decline in music enjoyment following …

Mediating Energy And Charge Transfer Dynamics Of Lead Halide Perovskite Nanocrystals Via Surface Chemical Approaches, Aaron S. Malinoski

Dissertations, Theses, and Capstone Projects

Energy and charge transfer are the fundamental mechanisms by which semiconductor nanocrystals interact with their external environment and underpin all light-conversion related applications. Lead halide perovskite nanocrystals (PNCs) are a relatively new class of semiconductor nanocrystals that possess a unique and dynamic surface chemical environment. Investigations into the influence of these surface chemical conditions on the electronic coupling between surface-bound molecular acceptors and the perovskite nanocrystals, and how the surface chemistry can be manipulated, in turn controlling the charge and energy transfer mechanisms, is the focus of this dissertation. Through ligand-shell engineering using commercially available, inexpensive small molecules, the surface …

Trans-Cyber Cinema: Digital Embodiment In Science-Fiction Films, Sophia R. Schrock

Dissertations, Theses, and Capstone Projects

This thesis aims to define the trans-cyber genre within cinema. By looking retroactively at a selection of nine films made across various decades and countries, this genre connects these films through their visualization and thematization of both trans and cyber embodiments, whereby the trans-cyber being emerges. Before the cinematic analysis and explanation of the three generic conventions selected for this thesis – transformation of body/gender; altered reality, memory, and temporality; and, radical death – the two intertwining theoretical frameworks will be established. This includes a brief summary of applicable transgender theory, and an introduction to cyborg theory (using Donna Haraway’s …

Scaling Limits Of Critical Observables Through The High Dimensional Incipient Infinite Cluster, Pranav Chinmay

Dissertations, Theses, and Capstone Projects

We give a general construction of the incipient infinite cluster in high dimensional percolation, and use it as a decoupling tool to rigorize geometric heuristics for analyzing the asymptotics of observables at criticality. Examples include demonstrating the limiting distribution of the chemical distance and full-strength asymptotics for k-point functions, which constitute foundational inputs for scaling limit results associated to critical clusters.

Implicit Attitudes Toward Hearing Aid Visibility: Conspicuous Versus Inconspicuous Hearing Aid Colors, Orly R. Ames

Dissertations, Theses, and Capstone Projects

Hearing aid stigma remains a significant barrier to treatment uptake, with device visibility frequently identified as a contributing factor. Although prior research has examined visibility in relation to hearing aid size and style, the role of color as a distinct aesthetic dimension has not been systematically investigated. The present study assessed whether hearing aid color affects implicit and explicit attitudes toward hearing aids and whether such evaluations differ across contexts. Twenty-six adults who were not current hearing aid users participated in an online quantitative multi-method study consisting of an Implicit Association Test (IAT) and self-report questionnaires. The IAT measured implicit …

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 …

A Comparison Of Manufacturers’ Claims Of Attenuation Rates In Non-Custom Earplugs, Skyler M. Shipley

Dissertations, Theses, and Capstone Projects

Recreational and social environments frequently expose individuals to high intensity noise environments; however, the use of hearing protection devices (HPDs) remains limited. This study evaluated whether non-custom, over-the-counter musicians’ earplugs provide attenuation consistent with manufacturers’ claims and whether cost is associated with performance. Six commercially available earplug models were tested using both human participants and a KEMAR manikin system. Attenuation was measured across frequencies from 250–8000 Hz (octave and inter-octave frequencies) and were tested using different ear tip sizes. Results indicated that several earplugs achieved attenuation levels comparable to or exceeding their advertised noise reduction ratings (NRR), though consistency varied …

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 …

Imagination And The Self: A Cross-Cultural And Cross-Disciplinary Study, Qianyi Qin

Dissertations, Theses, and Capstone Projects

This dissertation is an interdisciplinary investigation of the imagination and the self that engages with cognitive science, philosophy of mind, Buddhism, ethical theories, and a variety of perspectives from Asian and Western philosophy. I address the following questions in three interrelated chapters. First, what does it mean for the self to appear in imagination? In Chapter 1, against certain narrow understandings of the self in philosophy of language, I build a multidimensional model of the self in imaginative experiences to capture the rich phenomenology, drawing on empirical findings on memory and imagination. Second, can the self be removed from imagination? …
