Data collection and analysis were conducted concurrently using Charmaz’s iterative constructivist grounded theory approach, which included initial, focused, and theoretical …

Exploring Religious-Spiritual Struggles Among Muslim Immigrants In The Canadian Context, Ayse Erenay

Theses and Dissertations (Comprehensive)

Migration to a new culture and adaptation to a different lifestyle may cause emotional and psychological stress. In some cases, immigrants may experience religious and/or spiritual (R/S) struggles due to challenges to their beliefs and practices in the country they have immigrated to. Based on Pargament (2007, 2013)’s R/S struggle framework, these struggles may include questions about the ultimate meaning of life, one’s relationship with God, or doubt about one’s belonging within a religious or spiritual community. Muslim immigrants face unique struggles since Islamic teachings require Muslims to visibly practice their faith and reflect on God’s presence as a central …

Mixed Methods Insights Into Understandings Of And Stigma Towards Autism In Children And Young Adults, Natalia Gc Van Esch

Theses and Dissertations (Comprehensive)

BACKGROUND: Autism is widely stigmatized and misunderstood. Existing research using methods such as questionnaires finds that autistic individuals are often evaluated more negatively than their non-autistic counterparts. Unfortunately, this approach provides limited insight into the underlying representations of autism that individuals hold. The present study seeks to examine how children and adults define, describe, and represent autism, and how these representations relate to stigma. METHODS: In Part I, children participated in a semi-structured interview in which they defined autism and created autistic and non-autistic characters using a guided character-building task. Children then rated their characters on a series of social …

Fear Across The Map: A Cross-Municipal Analysis Of Fear Of Crime In Canada, Muhammad Ali

Theses and Dissertations (Comprehensive)

This study examines the predictors of fear of crime (FOC) across three Canadian municipalities: Hamilton, Ontario; Brantford, Ontario; and North Battleford, Saskatchewan. Data from 1,956 survey responses were analyzed to understand how certain factors shape FOC across different municipal contexts in Canada. This study uses descriptive statistics, reliability analyses, correlation matrices, and Ordinary Least Squares regression models to examine whether FOC, and the predictors of FOC, operate consistently across municipalities. The findings indicate that the predictors of FOC are relatively reliable across municipal contexts. However, the influence of the predictors of FOC can vary across municipalities. Importantly, the level of …

Children's Peer Selection In Stem: The Influence Of Gender, Ethnicity, And Disability, Meagan Girard, Kim P. Roberts

Theses and Dissertations (Comprehensive)

The present study examined how children’s peer selection in STEM (science, technology, engineering, and mathematics) may be influenced by gender, ethnicity, and physical disability. Sixty-four children (ages 6-12) from elementary schools in Southwestern Ontario completed three tasks: a simulated peer selection task, an attribution of ability task, and a stereotype belief questionnaire. In the peer selection task, participants were repeatedly asked to select one peer from a set of AI-generated photographs showing children who differed by gender (male, female), ethnicity (White, Black, East Asian), and physical disability status (able-bodied user vs. nondisabled). The Peer Selection Task was based on the …

Moral Identity And Cognitive Mechanisms In Moral Decision-Making, Zachariah I. Hamzagic

Theses and Dissertations (Comprehensive)

Moral identity can be broadly conceptualized as the degree to which an individual places moral values as directly relevant to their personal identity. A recently introduced developmental framework of moral identity argues that moral identity can be conceptualized as a lifelong goal. According to this theoretical framework, the moral identity goal (i.e., to be a moral person and engage in moral action) becomes stronger over the course of development by becoming more abstract (i.e., general), internalized (to satisfy personal ideals) and promotion (i.e., action) oriented. Additionally, the strength of the moral identity goal predicts moral functioning. To date there has …

Methylseleninic Acid Transformations In Nutrient Rich Water Containing Algae Exposed To Simulated Sunlight, Mikayla Cormier

Theses and Dissertations (Comprehensive)

Methylseleninic acid (MSA(IV)) is an organic form of selenium that has been suggested to be one of the most bioaccumulative forms of selenium in aquatic ecosystems. However, there have been no lab studies that confirm this, which is the reason this study was conducted. Once MSA(IV) and other bioavailable forms of selenium enter aquatic ecosystems, organisms such as algae take up these compounds which then bioaccumulate through the food chain. S. obliquus was exposed to 10 ppb MSA(IV) in 10% Bold’s basal medium (BBM) in a growth chamber to mimic environmental conditions over a 7-day period. Carbon traps and filters …

Identifying The Physical Activity Promotion Practices Of Obstetricians And Gynecologists: Patients With Endometriosis And Polycystic Ovary Syndrome, Allison P. Herman

Theses and Dissertations (Comprehensive)

Despite efforts to promote physical activity, many females in Canada do not meet recommended physical activity guidelines. For individuals with gynecological conditions such as endometriosis and polycystic ovary syndrome (PCOS), physical activity may aid in symptom management and improve daily functioning. Healthcare settings, including obstetrics and gynecology, represent an area of opportunity to promote physical activity among this population. This thesis aims to understand the physical activity promotion practices of Ontario-based Obstetricians and Gynecologists (OBGYNs) to patients with endometriosis and/or PCOS. A cross-sectional online survey was conducted to explore OBGYNs promotional practices and perceived factors influencing their engagement in physical …

" Who Am I Here?" Exploring The Racial Identity Development Of Chinese Adolescent International Students In Canada: A Constructivist Grounded Theory Approach, Wen Juan Song

Theses and Dissertations (Comprehensive)

Abstract

This dissertation explores the racial identity development and associated mental health challenges of Chinese Adolescent International Students (CAIS) in Canada, a population navigating complex intersections of race, age, migration, and belonging. Despite their growing presence in Canadian secondary education, CAIS remain understudied in both educational and mental health research, particularly in relation to racial identity development within Western, multicultural societies. Using a Constructivist Grounded Theory methodology, this study draws on in-depth interviews with twenty-five CAIS participants, including ten current high school students, three returnees to China, and twelve who remained abroad in post-secondary education or employment.  The study is …

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 …

Universities, Capital, And Democratic Vulnerability, Steven Dean, Dana Brakman Reiser

Faculty Scholarship

For many, the university serves as a crucial guardian of democracy. Still, the capitulation of leading American private universities to authoritarian pressure from the Trump Administration should not be terribly surprising. This Essay offers one reason why. It does so by focusing on the law governing private nonprofit universities. It examines both the origins and the impact of a fundamental tension between their charitable missions and their need for capital. It shows how the legal framework designed to protect these nonprofit universities from market pressures can actually intensify their vulnerability.

The so-called “nondistribution constraint” stands at the core of U.S. …

Blood Flow Regulates Metabolism In Hematopoietic Development, Pamela L Wenzel

Faculty, Staff and Student Publications

Blood flow modifies oxygen availability and biomechanical forces within the vasculature of the embryo as the hematopoietic system develops. The aorta-gonad-mesonephros (AGM) envelops the largest artery in the body and is a critical site for the emergence of hematopoietic stem cells (HSCs). Herein, I discuss the role of hypoxia-inducible factors (HIFs) and force as determinants of metabolism and fate determination. To address the effects of blood flow on hematopoietic development, I employ mouse embryo models and biomimetic culture. Real-time cell metabolic analyses show that oxygen consumption rates (OCR) and extracellular acidification rates (ECAR) are altered by flow in cultures of …

Engineering Mutation Clones In Mammalian Cells With Crispr/Cas9, Zijun Huo, Jian Tu, Rachel Shoemaker, Dung-Fang Lee, Ruiying Zhao

Faculty, Staff and Student Publications

CRISPR, Clustered Regularly Interspaced Short Palindromic Repeat, as a powerful genome engineering system, has been widely accepted and employed in gene editing of a vast range of cell types. Compared to zinc finger nucleases (ZFNs) or transcription activator-like effector nucleases (TALENs), CRISPR shows a less complicated process and higher efficiency. With the development of different CRISPR systems, it can be used not only to knock out a gene but also to make precise modifications, activate or repress target genes with epigenetic modifications, and even for genome wide screening. Here we will describe the procedure of generating a stable cell line …

Memory Warriors, Pluralists, And Abnegators In Constitutional Interpretation: An Essay On Jack Balkin's Pluralist Originalism In Memory And Authority, Jed Handelsman Shugerman, Zachary Shugerman Handelsman

Faculty Scholarship

Jack Balkin’s Memory and Authority: The Uses of History in Constitutional Interpretation brings into conversation the scholarly insights of constitutional theory, history, and the growing field of “the politics of memory,” especially the concept of the “memory entrepreneur.”

Balkin appropriately connects the memory wars in American constitutional law back to Eastern

European memory wars during the World Wars and their aftermath. Prompted by Balkin, we turn to Jan Kubik and Michael Bernhard edited volume Twenty Years After Communism (2014), which has become even more widely influential after Putin’s invasion of Ukraine and a new round of Eastern European memory wars. …

This qualitative study explores the ethical complexities of true crime media by examining how it intersects with criminal investigations, public perception, and victim advocacy. Through in-depth interviews with law enforcement officers, victim advocates, and true crime content creators, the study investigates differing attitudes toward the role of podcasts in active and cold cases. Using Colaizzi’s (1978) phenomenological method, data were analyzed to uncover shared and divergent themes across professional roles. Law enforcement participants voiced concerns over web- sleuthing …

An Energy-Stable Mixed Cg-Dg Scheme For A Full Shliomis Phase Field Model Of Two-Phase Ferrofluid Flows, Mahdi Gharehbaygloo

Doctoral Dissertations

"Ferrofluids are magnetic nanoparticle suspensions whose motion couples surface tension, flow field, magnetostatics, and magnetization dynamics. This dissertation develops, analyzes, and validates an energy-stable finite element method for a two-phase ferrofluid model that couples the Cahn-Hilliard equations with the full Shliomis model of single-phase ferrofluids, retaining its damping torque term, magnetic torque term, and magnetic stress term.

The spatial discretization is a mixed continuous Galerkin (CG) and discontinuous Galerkin (DG) formulation. It uses continuous ��2 elements for the phase field, chemical potential, velocity, and magnetostatic potential, discontinuous ��2 elements for the magnetization, and discontinuous ��1 elements for the pressure. The …

Harnessing Coherent-Wave Control For Sensing Applications In Scattering Media, Pablo Xavier Jara Palacios

Doctoral Dissertations

"Diffuse electromagnetic waves are widely used for non-invasive sensing and imaging in complex scattering media such as biological tissues. A fundamental limitation of such techniques is the scarcity of detected photons: as the source-detector separation increases to access deeper regions of the medium, the signal strength decays rapidly, leading to poor signal-to-noise ratio and limited sensitivity. This dissertation addresses this challenge through a combination of theory and computation.

We show that coherent control of the incident optical wavefront can compensate for the scarcity of detected photons that limits conventional diffuse optical imaging, typically performed in the near-infrared spectral region. By …

Location, Location, Reaction: How Mandatory Ip Disclosure Silences Critics And Sparks Backlash, Sirui Li, Ping Xu, Yue Guo

Political Science Faculty Publications

Previous research has identified two competing outcomes of regulatory disclosure for negative online sentiment: chilling effects, which suppress negative online sentiment, and reactance effects, which intensify it. In this study, we apply these theories to examine the impact of mandatory IP location disclosure on citizens' negative online sentiment expressed on Sina Weibo, a leading Chinese social media platform. We argue that the mandatory IP location disclosure can have opposite effects on negative online sentiment depending on the type of social media context. To test this, we use a quasi-natural experiment and analyze more than 160,000 comments posted before and after …

When The Internet Attacks, Craig Cowie

Cardozo Law Review

Courts have struggled with applying personal jurisdiction in cases involving intentional torts where the defendants act outside the forum, and the problem is particularly apparent and acute when the defendants use the internet to commit the tort. For example, is there jurisdiction when a defendant doxxes someone and calls for violence? What if they leave a bad Yelp review? Or tweet a defamatory statement? Courts have used many tests for determining whether personal jurisdiction is appropriate in these situations, but there has been relatively little recent scholarship on whether these tests are appropriate for analyzing personal jurisdiction in these contexts. …

Browser-Based Phishing Detection System Using Modern Web Technologies, Muhammad Arshad, Beena Sherin Kuriakose, Choo Wou Onn, Farhan Ahmad Siddiqui, Mohammad Shahid Kamal

Research Outputs: 2025-Present

Phishing remains one of the most persistent cybersecurity threats, exploiting human trust to steal sensitive information through deceptive websites. Traditional detection methods, reliant on blacklists and reactive reporting, offer limited protection against rapidly evolving zero-day attacks. To address these challenges, this study proposes and evaluates a hybrid browser-resident phishing detection framework that combines three complementary detection mechanisms: a locally executed Random Forest model using URL lexical features, lightweight real-time DOM structure analysis, and VirusTotal’s multi-engine reputation service. Communication between the client and server is optimised using gRPC over the QUIC protocol, ensuring secure, high-performance data exchange with built-in retry mechanisms …

Public Preferences And Trade-Offs In Critical Mineral Mining Development In The United States, Bamidele Joseph Ajiga

Masters Theses

Rising demand for battery-critical minerals has increased U.S. mining efforts, but projects often face public opposition. There is limited work on how individuals in affected regions evaluate trade-offs between economic and environmental risks.

This research applies a discrete choice experiment to examine individual preferences for proposed battery-critical minerals mining projects in Missouri, Minnesota, and Idaho. 1908 respondents evaluated hypothetical mining projects defined by jobs, state tax revenue, the proportion of tailings reprocessed, groundwater impacts, and surface water impacts, under gold and silver versus battery-critical mineral framings.

Conditional and mixed logit models were used to assess the importance of attributes, demographic …

It’S (Not All) Personal: Civil Litigation And The Values Of Rights Of Action, Hanoch Dagan, Avihay Dorfman, Issi Rosen-Zvi

American University Law Review

Existing approaches to civil litigation, both regarding its theoretical underpinnings and its practical instantiations, take diametrically opposing perspectives on the value of personal rights of action. Some view them as inviolable and thus vehemently oppose any mandatory arbitration clauses and treat class actions as presumptively dubious. Others have no principled objection to either, as they perceive personal rights of action as mere technologies that are painlessly dispensable if the substantive values underlying the claim at hand can be realized more effectively through a more efficient mechanism.

In this Article, we reject both of these ‘all or nothing’ approaches and offer …
