Obstacles And Supports As Experienced By Foster Youth In Higher Education: Ventura County Community College District, Breanna Webb

Theses and Dissertations

This qualitative phenomenological research study assesses the obstacles faced by foster youth and the support available to them while attending the Ventura County Community College District. As it currently stands, about four and a half percent of foster youth in the United States go on to earn a college degree. Very little research has been done to explore the effectiveness and outcomes of the support offered to foster youth. Data for this research study was collected using the General Self-efficacy scale and structured interviews. Each of the ten participants was given a demographics survey and a Self-Efficacy scale survey and …

The Relationship Between Cardiac Patient Beliefs And Experiences With Insurability And Their Decisions On Whether Or Not To Pursue Genetic Testing, Julia Schoeni

Theses and Dissertations

Since the enactment of the Genetic Information Non-Discrimination Act (GINA) in 2008, genetics providers have been incorporating conversations about GINA in pre-test counseling. There is currently limited evidence of the effects of personal or family histories of cardiomyopathy or aortopathy and associated genetic testing on patients seeking insurance policies not protected by GINA, including life, long term care, and disability insurance. This study aimed to determine whether individuals with a personal or family history of cardiomyopathy or aortopathy are having conversations about future insurability with their healthcare providers and how they perceive their ability to get these insurances when deciding …

Knowledge And Ontology Enhanced Approach To Natural Language Understanding (Koe-Nlu) In Computational Social Media And Healthcare, Naga Usha Gayathri Lokala

Theses and Dissertations

Natural Language Understanding (NLU) faces both opportunities and challenges as the amount of social media and healthcare data grows. This is particularly evident in context-sensitive applications such as evaluating cognitive health, identifying mental health symptoms, and monitoring drug abuse. Even though traditional NLU models work well for processing language in a wide range of areas, they often lack the ability to understand language in a specific domain, reason in context, and incorporate structured external knowledge. This dissertation talks about the Knowledge and Ontology Enhanced Approach to Natural Language Understanding (KOE-NLU), a new framework that is meant to make NLU systems …

Invention Beyond The Author, Jonathan Brent Butler

Theses and Dissertations

The following dissertation examines how what Michel Foucault calls the “author function” affects contemporary students of writing and examines some historical alternatives to this way of conceptualizing the writing process and the writer’s role in it. Chapter 1: Author (Dys)function describes the author function and its discontents, the problems of the Romantic conception of “genius,” and summarizes the following chapters. Chapter 2: Early Writing Instruction focuses on classical approaches to rhetorical instruction that emphasize habit and aim at the cultivation of a particular subjectivity characterized by the capacity to respond to shifting rhetorical situations; this chapter draws on the work …

In the first part of this work, heterogeneity is introduced onto the surface of silica nanoparticles via a sequential RAFT polymerization to afford a bimodal brush system. A densely grafted, short brush population is polymerized from the …

“Digital Shame Shift”: From Telling The Pain To Recording The Truth — Black Maternal Health And Digital Counter-Narrative Storytelling On Tiktok, Odera Covenant Ezenna

Theses and Dissertations

This dissertation explores how digital storytelling on TikTok is used to challenge medical racism, with a particular focus on Black maternal health. Guided by Critical Race Theory (CRT) and Critical Technocultural Discourse Analysis (CTDA), the study examines how TikTok users—ranging from Black mothers to healthcare professionals—create and circulate counter-narratives through two prominent campaigns: #BlackMaternalHealthWeek and #BlackMamasMatter. These digital stories serve as acts of resistance, disrupting dominant medical discourse and amplifying the lived experiences of Black birthing individuals. The research analyzes over 2900 TikTok videos posted between 2021 and 2024, identifying key themes, storytelling strategies, and rhetorical shifts over time. The …

Mental Silence For Emotional Intelligence Development, Mina N. Nandwani

Theses and Dissertations

While emotional intelligence is considered key for effective leadership, and perhaps the most vital competency for current and emerging leaders to cultivate, there appears to be uncertainty on how to develop it. This study examined how the practice of Sahaja Yoga Meditation (SYM) influences the development of emotional intelligence and contributes to the advancement of global leadership capacities, addressing a gap in the current literature. The conceptual frameworks of SYM, Daniel Goleman’s Emotional Intelligence Model, and the literature on global leadership, particularly Jeffrey Sachs’ Ages of Globalization, guided the research question. By implementing a qualitative phenomenological research approach, ten long-time …

Tate Speech: Radicalizing Rhetoric And Multi-Level Marketing Recruitment Strategies In The Manosphere, Carey J. Priebe

Theses and Dissertations

My study aims to uncover the discursive elements behind the gendered recruitment strategies that influencers in the manosphere use to pipeline men and boys into their multi-level marketing (MLM) companies. In the manosphere, male supremacy is presented as desirable and subversive, and MLMs take advantage of emotional and economic instability. My study examines the Twitter (X) account of the popular manosphere influencer Andrew Tate as I trace his rhetoric along a three-pronged gendered recruitment framework, a framework originally developed around women selling essential oils online and funneling their followers into radical alt-right politics. What are the similarities and differences in …

Functional Analysis Of Ligand Binding Domain 2 Of Outer Surface Protein C Of Borreliella Burgdorferi, Gavin Z. Chambers

Theses and Dissertations

Lyme disease, caused by the spirochete Borreliella burgdorferi, is the most common vector-borne infection in North America. A critical determinant of early mammalian infection is outer surface protein C (OspC), a highly variable lipoprotein that is indispensable for spirochete survival but whose precise function remains unresolved. OspC has been proposed to mediate diverse roles, including complement evasion, adhesion, tissue dissemination, and antiphagocytic activity, supporting the view that it is a multifunctional virulence factor. Structural studies have identified two putative ligand-binding domains (LBD1 and LBD2), with LBD2 forming a solvent-exposed crown at the membrane-distal end of the OspC dimer.

To …

Characterization Of Outer Surface Protein C Of Borreliella Role In Host Tropism, Kathryn Mf Chambers

Theses and Dissertations

The Lyme disease spirochetes, Borreliella spp., are maintained in nature through a complex enzootic cycle involving Ixodes ticks and a diverse set of reservoir hosts. The outer surface protein C (OspC) of the bacterium is an essential virulence factor required for transmission from ticks and early infection of mammals. Deletion of ospC abolishes infectivity, yet the precise molecular mechanisms underlying OspC function remain incompletely defined. In this dissertation, I examined the contribution of OspC type identity to host specificity. OspC is highly diverse, with over 30 genetically stable types described. While intra-type sequences are conserved (>95% amino acid …

Imagine Being Free: Decolonizing Actor Training In University And Conservatory Programs, Hope R. Ward

Theses and Dissertations

While blackface is considered the first proper form of American theater, I want to consider how the auction of enslaved Africans functioned as the original form of American theater. The auction block acted as a kind of interactive performance in which enslaved bodies were surveilled and evaluated as a kind of spectacle. In many ways, the auction block inaugurated White viewing practices of the Black body that reverberated in the day-to-day practices of slavery and subsequent visual media like the refashioning of blackface minstrel tropes within contemporary entertainment (plays, television, film). In Imagine Being Free: Decolonizing Actor Training in University …

The Trauma-To-Prison Pipeline: A Multi-Level Theoretical Framework Exploring The Intersection Of Inequality, Trauma, And Exclusionary Discipline, Dana Ainsworth

Theses and Dissertations

The school-to-prison pipeline (STPP) is a widely recognized and extensively studied metaphor used to describe the process by which school discipline policies increase the risk of juvenile justice system involvement, particularly among historically marginalized populations. While it has been instrumental in shaping educational policy, the STPP framework has not evolved to account for the critical impact of trauma on learning and behavioral outcomes. Furthermore, it overlooks the role of systemic inequality that increases trauma exposure and produces concentric patterns of marginalization.

Drawing on research across the fields of education, public health, sociology, and criminal justice, this study proposes a theoretical …

Teaching Under Political Influence: A Multiple Case-Study Examining The Impact Of Curricular Restriction Policy On Community-Connected Instruction (Cci) In Full-Service Community Schools (Fscs), Isaiah Moore

Theses and Dissertations

Scholars describe the political landscape as polarized, where partisanship —loyalty to a particular political party— dictates one’s beliefs. In education, this partisanship is best exhibited through conservative policy restricting curricula regarding race, racism's pervasiveness, gender identity, and how history is taught in public schools. Conversely, Community-Connected Instruction (CCI) affirms students’ culture and builds critical thinking skills in an authentic environment. While studies suggest its benefits to students, the current curricular restriction policy challenges its usage. This form of teaching is closely associated with Full-Service Community Schools (FSCS), which primarily serve underserved student populations. This study examines how FSCS educators in …

The Bitch And The Boogeyman: Violence Against Women And Gendered Morality In American Slasher Films, Davis A. Smith

Theses and Dissertations

This research examines the relationships between on-screen depictions of violence in American slasher horror films and depictions of gendered morality of victims. Slashers are a subgenre of horror film that arose out of the exploitation cinema movement of the 1970s that are characterized primarily by the presence of one or more human killers inflicting violence on a group of protagonists, typically through the use of bladed weapons. Data collected comes from a comprehensive set of thirty-six American slasher films that received a wide theatrical release, with exemptions for films whose primary genre is not slasher and only selecting three films …

Food Waste Renaissance: From The Table, For The Table, Yasamin Shaikhi

Theses and Dissertations

What if waste could be seen as a valuable resource rather than a burden? Food Waste Renaissance (FWR) explores innovative ways to transform excess food and byproducts into sustainable design materials. In Qatar, where food waste constitutes approximately 60% of urban waste, FWR promotes a shift in perception rather than attempting to resolve large-scale waste management issues. By fostering a culture where surplus becomes a resource, it inspires individuals, designers, and communities to embrace and contribute to a circular economy. FWR examines rice and date byproducts as biodegradable raw materials for lamps, bringing material from the table back to the …

Inherited Wounds: Navigating Intergenerational Trauma Through Cooperative Play, Ayza Sheikh

Theses and Dissertations

'Strength' for Pakistani women is often defined as compromise, sacrifice, and silence. This definition has shaped intergenerational struggles in which women's self-narratives are constructed through suppression. Inherited Wounds seeks to address the trauma of suppression by creating a safe space for expression that fosters reflective and emotion-driven dialogue between Pakistani mothers and daughters.

Using interactive storytelling and embodied play, I developed a choice-based, narrative-driven video game and accompanying gesture-based controller. The game unfolds across childhood, marriage, and motherhood, mirroring the cycle of intergenerational struggle. Navigating choices in the game requires physical, intimate cooperation. The game uses the protagonist’s life as …

Existing In The Context: A Conjunctural Analysis Of Kamala Harris Memes, Amaya Mcneal

Theses and Dissertations

Political memes have become a common way for people to express their political views online, helping politics reach young adults who weren’t previously interested. Consequently, politicians have begun sharing and creating memes themselves. The memeification of American politics has diminished debate about ideas, ideals, issues, and people’s vital interests, debasing voters by treating them not as citizens but as passive “consumers” and “spectators” of mediated politics. This paper helps make sense of this crisis, focusing on the example of former Vice President Kamala Harris. Vice President Kamala Harris' memeified presidential campaign during the 2024 U.S. election targeted voters through a …

You Go, I Will Wait, Rasim Bayramov

Theses and Dissertations

On the other side of the coast, a hand is waiting. On the other side of the shore, someone is waiting for you to come. This space between you and them is an asymptote. The more you wait, the colder the pan is to the hand. But the salt of the sea will cover and warm your hand. There’s much to play with while you wait. The destination is only a promise, a figure disillusioned. Waiting spaces are enchantingly altering

in their premise. A bureaucratic fantasy with no avail and no ending. Systematically accumulated levels of power and control lies …

The Bacteriostatic, Regenerative, And Immunomodulatory Properties Of Extracellular Matrix Particles For Lung Injury, Keera P. Rhoads

Theses and Dissertations

Acute respiratory distress syndrome (ARDS) is a prevalent, life-threatening lung condition, affecting nearly 200,000 Americans annually, with a 40% international mortality rate. There is no cure for ARDS, and current pharmacological treatments have limited effectiveness. Symptoms can be mitigated with mechanical ventilation, though this often leads to ventilator-induced lung injuries (VILI) and puts critically ill patients at risk of infections, including ventilator-associated pneumonia (VAP). A promising therapeutic is the extracellular matrix (ECM), a complex network of structural proteins and bioactive molecules that has been shown to have anti-inflammatory properties and prevent fibrosis. We aim to utilize the regenerative and immunomodulatory …

Targeting The Achilles’ Heel Of Lung Cancer Induced By Oncogenic P53, Brandon G. Velasco

Theses and Dissertations

Mutations of the tumor suppressor gene, TP53, are the most prevalent oncogenic mutations in lung cancer, occurring in up to 70% of human non-small cell lung cancer (NSCLC). The majority of mutations in p53 are missense mutations that cause not only a loss of tumor suppressor function, but also gain of oncogenic functions, like tumorigenicity, immune suppression, and chemoresistance. Previous studies have shown that the depletion of gain-of-function (GOF) p53 or disruption of its ability to transactivate the expression of genes related to oncogenesis eliminates its tumorigenic properties indicating a dependency of human lung cancer cells expressing GOF p53 …

Radical Hope Amid Generational Oppression And Puerto Rican Well-Being, Natalia Gomez Giuliani

Theses and Dissertations

Oppressive systems (e.g., colonialism, racism, capitalism) create a disparate distribution of power that, through various mechanisms, negatively impacts the health and well-being of members of the oppressed group. Boricuas have experienced over 500 years of oppression, with the island currently maintaining a colonial relationship with the United States. As these adverse effects of oppression are identified, the need for protective factors (e.g., hope) has emerged. This study explored how islander Boricuas practice radical hope, understand their history of oppression and resistance, and how they perceived it to impact their overall well-being. Utilizing a phenomenological qualitative approach, I conducted 15 semi-structured …

Automated Treatment Planning Framework For Cervical Cancer In Brachytherapy, Suman Gautam

Theses and Dissertations

Brachytherapy (BT) is a critical treatment modality for cervical cancer that delivers ionizing radiation directly to the tumor using intracavitary (IC) and/or interstitial (IS) applicators. In high dose-rate (HDR) BT, a remote afterloader guides the radioactive source to specific dwell positions for defined durations, known as dwell times, allowing for a conformal dose to the tumor while minimizing exposure to surrounding organs at risk (OAR). However, due to the inherent nature of ionizing radiation, some dose to OARs is unavoidable, creating a fundamentally conflicting objective in treatment planning: maximizing tumor coverage while minimizing OAR dose. This characterizes the problem as …

Identification Of Mechanisms Associated With Electronic Nicotine Delivery System Use For Weight Control In Young Adults, Gabrielle Maldonado

Theses and Dissertations

Electronic nicotine delivery system (ENDS) use continues to rise among young adults in the United States, raising public health concerns as the harmful effects of ENDS continue to rise while tailored cessation programs lag. Weight control motives may drive ENDS initiation and frequent use, particularly among sexual and gender minority (SGM) populations, who report higher ENDS use, body dissatisfaction, and disordered eating behaviors than those who identify as heterosexual and cisgender. Understanding these behaviors, their mechanisms, and at-risk populations is critical for improving public health. Seven hundred and eight young adults (ages 18–30; M = 26, SD = 3.3) reporting …

Therapy-Induced Senescence In Cancer: Developing Senolytic-Based Combination Strategies To Delay Re-Emergence Of Triple-Negative Breast Cancer, Eesha Chakraborty

Theses and Dissertations

Therapy-induce senescence (TIS) represents a major biological outcome of many anticancer treatments and is increasingly recognized as a strategic vulnerability in triple negative breast cancer, which is a highly aggressive subtype with limited therapeutic options and frequent relapse. Here, we probed TIS as a primary cellular response that may ultimately compromise long-term outcomes using standard chemotherapeutic agents in TNBC as well as the antibody-drug conjugate sacituzumab govitecan (SG). Both chemotherapy and SG reliably induced pronounced senescence across TNBC models, yielding durable growth arrest, however, also generating a persistent reservoir of viable tumor cells capable of eventual proliferative recovery, a hallmark …

Plza Rna Chaperone Activity In Borreliella Burgdorferi Is Modulated By C-Di-Gmp, Dhara T. Patel

Theses and Dissertations

Lyme disease (LD) is the most common arthropod-borne disease in North America and is caused by the spirochete, Borreliella burgdorferi. LD spirochetes are maintained in an enzootic cycle of Ixodes species ticks and a vertebrate reservoir. The secondary messenger molecule c-di-GMP plays a crucial role in adaptive responses during the enzootic cycle. PlzA is the sole c-di-GMP-binding protein identified to date that is encoded by all Borreliella burgdorferi isolates. PlzA has both c-di-GMP-dependent and c-di-GMP-independent functions and is required to complete the enzootic cycle. The full range of PlzA regulatory activities has yet to be fully defined. We determined …

Exploring The Role Of Host Immune Responses And Bacterial Sensory Pathways In The Development Of Treponema Denticola-Mediated Periodontal Disease, Annie N. Hinson

Theses and Dissertations

Periodontitis is a chronic inflammatory disease driven by dysbiotic microbial communities and maladaptive host responses. Treponema denticola, a spirochete pathobiont, is strongly associated with disease severity. However, the molecular mechanisms underlying its interaction with host tissues and regulation of virulence remain incompletely understood. This work examines both the epithelial immune responses and bacterial transduction systems that shape T. denticola pathogenesis. Transcriptomic analysis of gingival keratinocytes revealed IL-36γ as the most highly induced cytokine following infection with T. denticola. Functional studies demonstrated that IL-36γ induction occurs in a dose- and time-dependent manner through TLR2/6 signaling, requiring the NF-κB, PI3K/Akt, and …
