The Assessment Of Implicit Bias Among Police Personnel: A Systematic Review, Emily Deutsch

Theses and Dissertations

Due to the essential and powerful role police officers play within the communities they serve, systematic racism in law enforcement has become a key topic of public discourse, including increased demand for evidence-based changes in police selection. This includes recommendations or requirements to assess implicit bias in police candidates (e.g., California Assembly Bill 846). Implicit bias refers to the spontaneous/automatic associations or evaluations made of members of a particular group (Kim & Roberson, 2021). The California Commission on Peace Officer Standards and Training’s (POST’s) Bias Assessment Framework provides recommendations to police psychologists on the assessment of implicit bias, but curiously …

Either At The Table Or On The Menu: Strategies For Enabling Practitioner-Led Policy Co-Creation In Education Systems, Robert Reyes

Theses and Dissertations

Demands for educational transformation present unparalleled challenges for practitioners, as successive reform initiatives often exclude their voices and discount their expertise. Despite empirical evidence recognizing educators as key agents of change, systemic barriers continue to hinder their participation in policy-centered decision making. This study underscores the urgent need for education systems to invest in practitioner capacity-building, structural enablement, and cross-sector collaboration to create a more equitable and responsive future for education governance. A qualitative phenomenological approach was employed to explore how best to prepare and enable PK-12 practitioners to co-create education policy at the state level, aiming to empower them …

Resilience And Stress: Trauma, Grit, Resilience And Perceived Organizational Support In First Responders, Paige Gallas Parker

Theses and Dissertations

First responders comprise an underserved and under-researched population, despite consensus that their work involves exposure to potentially traumatic events. Inconsistent definitions of “first responder” and unclear prevalence rates of posttraumatic stress symptoms (PTSS) limit efforts to assess and promote resilience. This study examined the relationships between grit, resilience, perceived organizational support, and trauma symptoms in a sample of 234 first responders (69% firefighters, 29% lifeguards) employed by a large West Coast fire department. Measures included a demographics questionnaire, the Professional Exposure to Traumatic Events (PETE), the Posttraumatic Stress Disorder Checklist (PCL-5), the Connor-Davidson Resilience Scale (CD-RISC-10), the Short Grit Scale …

Practitioner Perspectives On Barriers And Opportunities Shaping Contemporary Dei, Carlen Arima

Theses and Dissertations

This study examined the lived experiences of diversity, equity, and inclusion (DEI) practitioners to understand the barriers and opportunities shaping their work in the current landscape. The study identified conditions for success, including two organizational conditions (authentic leadership commitment and strategic business alignment), three practitioner-driven strategies (human resource operations and systemic integration, use of data and metrics, and adaptive framing to increase adoption), and three persistent barriers (leadership support without operational follow-through, funding and time constraints, and structural marginalization of DEI). A central finding revealed that leadership commitment was both the most cited enabler of success and, when lacking operational …

To Be Loved Is To Be Seen: Gazing As A Form Of Interpretation In The Turn Of The Screw, Yasmin Mezayek

Theses and Dissertations

The heated discourse that would follow Henry James’s novella “The Turn of the Screw” centered on whether the ghosts were real or not. With Shoshana Felman’s groundbreaking article “Turning the Screw of Interpretation” a new-found focus on the ambiguities, as opposed to finding a singular, definitive meaning of the novella would usurp the Freudian and anti-Freudian arguments. With the governess’s sight being the main source of debate, reading the novella through the Lacanian lens of the Gaze, the Imaginary, and the Symbolic offer unprecedented explanations and arguments for the governess’s behavior. Given the contemporary shift to discussing the ambiguities of …

Yet, excessive and repetitive social media usage may become problematic, to the extent that the behavior takes the form of a psychological addiction. The primary objective of this study was to explore prospective factors that could predict the psychological dependency on social media applications, characterized as social media addiction (SMA). Paralinguistic Digital Affordances (PDAs) are “likes” one receives on social media and may predict SMA via the expected gratification attained when a PDA is received. Cognitive processes, assessed with a general executive functioning index and the n-back …

Love Letter, Amy S. Duval Ms

Theses and Dissertations

I applied to graduate school to reconnect with and better understand my studio practice, acquire language, and to disrupt my known ways of making. Generally speaking, I see my practice as being about being seen, and unseen, and the pain and pleasure of being perceived. I’ve learned about my ways of being in the studio. I’ve come closer to speaking honestly about my relationship with my materials, processes, tools, how I value my own labor, and how this informs my work. I am grateful for the cascade of small epiphanies that came and left me while I worked in my …

Strengthening Traffic Safety Laws On The Crow Indian Reservation, Darcy Merchant

Theses and Dissertations

The Crow Indian reservation is located in south-central Montana. The reservation is one of the largest land-based tribes in Montana, encompassing an area of over three thousand square miles. The reservation borders the state of Wyoming to the south and the Northern Cheyenne Indian reservation to the east. The reservation features a comprehensive transportation system that encompasses tribal, county, state, and federal roadways. Drivers and passengers who travel on these roadways are at higher risk for fatal and severe injury-related motor vehicle crashes than those in other reservations. This situation largely stems from the critical absence of targeted traffic safety …

She Works Hard For The Money: Black Women Entrepreneurs, Business Networks, And Entrepreneurial Success, Dejuan Erica Price

Theses and Dissertations

Although Black women launched an estimated 2.08 million businesses in 2023 (accounting for 14.8% of all women-owned firms), they remain significantly underrepresented among high-growth, well-capitalized enterprises.

Critical Success Factors For U.S. Fintech Startups In The Post-Covid-19 Era: Applying The Entrepreneurial Ecosystem Framework, Wen Hua

Theses and Dissertations

The extradentary surge of financial technology (fintech) enterprises has fundamentally transformed contemporary financial markets, yet extant scholarly literature exhibits a notable absence of a unified and theoretically grounded framework for explicating fintech startups’ success (Hamza et al., 2025). This dissertation addresses this theoretical lacuna by synthesizing an integrative entrepreneurial ecosystem framework to illustrate the critical success factors (CSFs) that catalyze fintech venture performance (Conley, 2014). Drawing upon established theoretical foundations, this research employs a multi-method research design, and develops a comprehensive framework for fintech startup companies’ success. The methodological approach commenced with a systematic meta-analysis of theoretical paradigms, establishing a …

Psychotherapy And Changes In Adult Attachment: A Systematic Review, Meghan Kussman

Theses and Dissertations

Attachment insecurity is a transdiagnostic vulnerability factor linked to a wide range of emotional and relational difficulties. Although early attachment patterns tend to be relatively stable, research indicates that attachment orientations can change over time, particularly in response to significant relational or therapeutic experiences. This systematic review examined 39 empirical studies published between 2000 and 2024 to determine whether engagement in psychotherapy is associated with changes in adult attachment security. Eligible studies assessed attachment both pre- and post-treatment using validated self-report measures (e.g., Experiences in Close Relationships Scale; ECR) or interview-based measures (e.g., Adult Attachment Interview; AAI), and reported statistically …

Purpose-Driven Curriculum For 9th-12th Grades For Adulthood Careers & Life Gratification, Destiny Krystle Chioma Nnadozie

Theses and Dissertations

A purpose-driven or purpose-based curriculum is not the standard required for high schools in the United States. Students in grades 9th-12th are educated based on a curriculum that covers mathematics, English, science, and social studies (De Roux & Riehl, 2022; Xiao et al., 2018). The unique individual purpose of each student, realized while in high school, is not considered a priority, leaving students to enter their adult careers lacking true career fulfillment due to this misalignment (Baroudi et al., 2017; S. Lyons et al., 2015; H. Wu, 2024).  Using a qualitative systematic review research design, this study aimed to explore …

Best Practices Of Vietnamese Catholic Priests Leading Vietnamese Community Parishes In Orange Diocese, Phuc Viet Nguyen

Theses and Dissertations

The Catholic Church is the largest church all over the world and is also the largest one in the United States (Pew Research Center, 2013). Over the past decades, great crises inside the Catholic Church have raised significant concerns for its leadership practices, especially for its governance and administration on the diocese and parish level. Moreover, the issue of immigrants also compounds the problem when there are different ethnic communities inside one single parish. In some dioceses like Orange County, which is one of the most culturally diverse dioceses in the United States (Diocese of Orange, 2018), the urgency of …

Taking It To The Streets: A Comparative Case Study Of Urban Street Medicine Programs For The Unhoused Population, Dolly Dimple Harris

Theses and Dissertations

“Taking it to the Streets” originated from the 1960s social and political activism (Doohan & Mishori, 2019). The term reflects the 1990s movement when a Philadelphia physician decided that caring for the unhoused population was necessary and started street medicine. Street medicine is an alternative medical approach to formal healthcare intended to address unhoused individuals in their lived environment. In the street medicine model, healthcare providers offer medical support for the unhoused in alleyways, parks, under bridges, and encampments. The purpose of this comparative case study was to examine two street medicine programs’ administrative processes and how they provide healthcare …
