A Constructivist Grounded Study: At The Intersection Of Religion And Intimate Partner Violence In The Context Of An Ultra-Orthodox Jewish Community, Lauren Kalvari

Theses and Dissertations (Comprehensive)

This constructivist grounded theory study, informed by a critical intersectional lens and guided by symbolic interactionist theory, explored how Ultra-Orthodox Jewish women experience and navigate intimate partner violence (IPV) within their religious and community contexts. Ten participants, recruited through purposive and theoretical sampling, were separated or divorced from abusive partners for at least eight months and had engaged in psychotherapy, allowing for retrospective meaning-making. Each participant completed one to three in-depth interviews on IPV, community responses, spiritual conflict, and recovery. 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 …

Sex Differences In The Use Of Cognitive Strategies In Brown-Headed Cowbirds (Molothrus Ater), Nicole E. Robinson Ms.

Theses and Dissertations (Comprehensive)

Cognition is widely believed to be adaptive, yet few studies directly show that variation in cognitive performance is related to fitness. Brown-headed cowbirds (Molothrus ater) provide a powerful system for addressing this gap because brood parasitism creates strikingly different reproductive problems for females and males. Females face the spatial demands of nest-prospecting, whereas males face social and competitive demands associated with access to mates. Across five experiments, cowbirds were tested on an outdoor foraging task designed as an analogue of nest prospecting, with manipulations of retention interval, cue conflict, and breeding condition, followed by observations of reproductive behaviour. …

Is Prosocial Behavior A Unique Correlate Of Academic Success In Emerging Adulthood?, Jacqueline Di Biase

Theses and Dissertations (Comprehensive)

Prior developmental research has frequently linked prosocial behavior to stronger academic functioning during childhood and adolescence (Cruz et al., 2024; Gerbino et al., 2018; Oberle et al., 2022), yet its relevance to academic success in emerging adulthood remains unclear. Guided by a Positive Youth Development (PYD) framework, the present study sought to address gaps in emerging adulthood research by examining the academic relevance of prosocial behavior while accounting for influential developmental assets and testing its independent contribution to academic achievement. Undergraduate students (N = 501) completed a cross-sectional self-report survey assessing prosocial behavior, self-control, dutifulness, sociability, and cumulative grade …

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 …

Exploring The Role Of Cognitive Load In Applicant Faking And Prevention Methods, Sabah Rasheed

Theses and Dissertations (Comprehensive)

Personnel selection is critical to organizational success, and personality assessment is widely used to identify the best job candidates. However, applicant faking threatens the validity of personality assessments in high-stakes contexts. Faking is widely assumed to be more cognitively demanding than honest responding, and several faking-prevention methods rest on this premise. This dissertation examines that assumption across three studies using the dual-task paradigm to impose cognitive demands during personality assessments. Study 1 used a verbal digit-span task with a student sample and limited faking on the three job-relevant personality composites. Study 2 used a visual dual-task with a student sample …

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 …

Timing, Targets, And Teaching: How Employee Help-Seeking Influences Downward Knowledge Sharing, Nicholle E. Kovach

Theses and Dissertations (Comprehensive)

Knowledge sharing between managers and employees is critical for employee development and organizational performance. However, managers differ in whether they share knowledge, and in the type of knowledge shared. While solution-oriented knowledge offers immediate answers to improve short-term performance, process-oriented knowledge promotes long-term learning and employee development. The purpose of my dissertation is to investigate factors that influence managers’ knowledge-sharing decisions.

I conduct two studies to investigate my predictions. In Study 1, I examine how the timing of employee help-seeking requests, the source of performance targets and employee historical performance influence the type and quality of managers’ knowledge-sharing responses. Drawing …

The Effects Of Environmental Complexity On Brain Development And Personality Expression In Western Hognose Snakes, Gokulan Nagabaskaran

Theses and Dissertations (Comprehensive)

There is growing interest in snake cognition, personality, and welfare as more snakes are kept as pets, yet little research has been conducted. The effects of enrichment and environmental factors have been well documented in other taxa, and recent evidence suggests that snakes may benefit in similar ways. This dissertation investigated the impact of environmental and social enrichment on personality expression, personality stability, and brain development. Western hognose snakes (Heterodon nasicus) were used as the model species, as they are a popular choice in the pet trade. This allows the research to be readily translatable to husbandry practices of many …

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 …

Religious And Spiritual Struggles: The Stories Of Nigerian, Immigrant, Christian Women In Waterloo Region, Halima D. Fuller

Theses and Dissertations (Comprehensive)

ABSTRACT This research investigates religious and spiritual struggles among Nigerian, immigrant, Christian women in Waterloo Region. Twelve women settled in the region for six months to 11 years participated in the study. Qualitative methodology, narrative inquiry, and a storytelling paradigm informed the research. Semi-structured, in-depth interview questions were used to explore the experiences of religious and spiritual struggles. A meticulous review identifies a scarcity of literature on religious and spiritual struggles in the context of immigration. However, immigration challenges such as language barriers, precarious employment, and mental health issues are well-documented (Bauder, 2012; Beiser & Hou, 2016; Berry et al., …

Eeg Correlates Of Tactile Synchrony, Devon K. R. Gallagher

Theses and Dissertations (Comprehensive)

New research on the tactile system has suggested that cortical representations of body parts are not fixed, as previously thought, and are instead dynamically maintained through constant sensorimotor information and feedback. Within the somatosensory cortex (S1), the capacity for both permanent and temporary changes have been the topic of ongoing research. The current study aimed to corroborate whether 24 hours of a finger adhesion manipulation is sufficient to elicit behavioural and electrophysiological correlates from cortical reorganization of digit representations in S1, using a behavioural paradigm outlined by Kolasinski et al. (2016). Through electroencephalography (EEG) recording during a tactile discrimination task, …

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 …

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 …

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 …

Evaluating The Role Of Provider Perspective And Their Impact On Individuals With Sickle Cell Disease In The United States Of America, Jadyn C. Oppong

Undergraduate Theses and Capstone Projects

Individuals affected by invisible disabilities, such as Sickle Cell Disease (SCD), have additional challenges beyond the physical manifestation of their disease, which is otherwise unknown externally. SCD patients continually consider disease manifestation in everyday life and experience varying degrees of disease perception in and out of the hospital environment. Additional considerations of a patient’s other intersecting identities, such as race and cultural identity, call attention to the sociological landscape of the United States of America. The dynamics observed within this landscape can be seen through the symbolic interaction of these identities with the invisible disability identity, in which a compounding …

A Qualitative Study: How Does The Underrepresentation Of Black American Contributions To American Society In K-12 Curricula Affects Black Students' Self-Perception?, Deniece M. Rogers

Theses and Dissertations from DePaul University

This qualitative phenomenological study examined how the underrepresentation of Black American history in K–12 curricula influences individuals’ understanding of American society, identity, and cultural belonging. Using open-ended questionnaires distributed via Qualtrics, thirty-seven participants reflected on their educational experiences, the extent to which Black American history was included, and how its omission shaped their self-perception and social awareness. Guided by Critical Race Theory (CRT) and The 1619 Project, the study was organized around six a priori themes identified in existing scholarship: Awareness of Historical Omission, Identity and Self-Perception, Social and Cultural Impact, Reactions to the Education System, Emotional Responses, and Broader …

Soma Body Help Me! How The Superwoman-Schema And Marianismo Contribute To Weathering Among Collegiate Women, Chantelle Christina Miller

Theses and Dissertations from DePaul University

Educational attainment is widely conceptualized as a protective factor for health; however, growing evidence suggests that these benefits do not accrue equally across social groups. Women of color, particularly Black and Hispanic/Latina women, experience persistent health disparities despite increasing levels of educational attainment, raising critical questions about the physiological and psychosocial costs of upward mobility. The weathering hypothesis posits that chronic exposure to structural inequities accelerates physiological deterioration over time, while related frameworks such as skin-deep resilience and marginalization-related diminished returns highlight the hidden health costs of sustained high-effort coping. Gendered cultural schemas including the Superwoman-Schema among Black women and …

Developmental Risk In Context: A Network Perspective On Adversity And Resilience, Alexander J. O'Donnell

Theses and Dissertations from DePaul University

Exposure to childhood adversity is common, unequally distributed, and strongly linked to negative outcomes across development. Efforts to improve well-being should consider protective factors across multiple levels, in addition to addressing the structural causes of adversity. Traditional approaches to resilience, such as cumulative risk and interaction models, provide useful information but do not capture the full complexity of how adversities and protective factors are connected. Network analysis offers a way to examine these interconnections by mapping associations and clusters of variables. This study uses data from the National Study of Adolescent to Adult Health (Add Health) to explore the combined …
