The Inequitable Access: Black And Latinx Students In Ap Courses, Jean C. Woolcock

Dissertations

This study posits that in American high schools, the preparation of Black and Latinx students, starting from the freshman year, can be effective in helping to increase their participation in Advanced Placement (AP) courses. Structural inequities, in how schools are resourced, affect the ways in which Black and Latinx students are denied equal opportunities. On the contrary, members of their peers do obtain this kind of preparation. As a framework, Critical Race Theory (CRT) contends that race, the law, and power are deeply ingrained in maintaining established bastions of wealth and dominance. Gaps in opportunity and achievement spill over into …

Educator Perspectives Of High School Long-Term English Learners, Martin Gutierrez Jr.

The research reviewed teacher and administrator perceptions by focusing on three high school teachers who taught Long Term English Learners during the study period to understand the reclassification process. The researcher interviewed a district-level administrator to understand institutional policies and procedures that determine LTEL student identification and reclassification processes. The researcher presented their autoethnographic narrative to explore how holistic measures support multilingual …

Bilingual Latinx Adolescents Experiences In A Predominantly White Institution: A Mixed Method Study, Danieli Marie Mercado Ramos

Dissertations

Extent scholarship has provided insight into how Latinx adolescents actively experience exclusion. These adolescents are often the targets of microaggressions tied to their language (Gonzalez et al., 2018), ethnicity, race, and intersecting identities--such as being bilingual Latinx students--which serve as reminders that they do not belong. However, little is known about Spanish-English bilingual Latinx adolescents and how their heritage language plays a role in predominantly white spaces and institutions. This convergent parallel mixed methods study explored how Spanish-English bilingual Latinx students in the Midwest described their experiences in a predominantly white institution (PWI). A total of 42 Spanish-English bilingual Latinx …

Evolution Of Bacteria: The Subsequent Relationships Between Different Species And Their Hosts, Helen Appleberry

Dissertations

To explore the relationship between two recently identified bacterial species (S. anginosus and S. urinae), three aims were designed. First, niche ranges were identified via two metagenome databases. Different niche ranges were identified between the two groups. S. urinae was more specific to the urogenital tract. S. anginosus appeared to be present across human anatomical niches. Secondly, specific genes to the S. urinae group were identified. This gives insight into the genomic and phenotypic differences previously identified. Thirdly, a temporal study was created to view S. urinae in female urine over 8 weeks. This showed stability in the urinary microbiome …

Reconceptualizing Christian Nationalism, Robert Stevenson

Dissertations

This thesis sets out to critically engage with existing research on Christian nationalism. It argues that current research suffers from a methodological focus that is too broad, and theoretical grounding that is too imprecise, both of which prevent researchers from grasping the full scope and intent of Christian nationalism, as imagined by Christian nationalists themselves. Drawing on data collected from X accounts (formerly Twitter) of Christian nationalist users, Christian nationalist podcasts, and Christian nationalist books, it employs qualitative content analysis, mapped to Bourdieusian field theory to provide a structured approach for the understanding complex data involving multiple spheres of power, …

Glioblastoma (GBM) is the most common and most aggressive form of adult cancer in the central nervous system, with GBM accounting for the majority of all malignant brain tumors. GBM is currently considered to be an incurable form of cancer, with over 14,000 patients diagnosed in the United States last year. Given the success of immunotherapy for treating other types of cancer, our group has investigated the possibility of therapeutically neutralizing immunosuppressive indoleamine 2,3 dioxygenase 1 (IDO1) in patients with GBM. Canonically, IDO1 is an immunosuppressive cytoplasmic enzyme that catalyzes the first step in metabolizing L-tryptophan into L-kynurenine (ie. ↓L-Trp→↑L-Kyn). …

Capturing Diverse Adolescents’ Social Contexts: The Development Of An Ethnic-Racial Microaffirmations Scale For Peer Interactions, Maria Radulescu

Dissertations

The development of a strong and positive sense of ethnic-racial identity (ERI) has been identified as an asset for ethnically and racially marginalized adolescents. Peer interactions during the adolescent years can support ERI development. In particular, a subtle micro-level form of peer support—microaffirmations—may be protective for ERI processes. However, the field of microaffirmations is very small, and there is no scale that captures adolescents’ experiences of ethnic-racial microaffirmations from their peers. The current study developed an ethnic-racial peer microaffirmations scale based on extant literature and feedback from 4 focus groups with 22 sophomore high school students. Findings indicated that 5 …

The Bacterial Sensing Nuclear-Oligomerization Domain 2 Receptor In The Brain: Location And Potential Function, Julia Smyth

Dissertations

Nucleotide-binding oligomerization domain-2 (NOD2) is a cytosolic receptor, activated by bacterial peptides that initiates innate immune responses through nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), and Caspase-1 pathways. While the role of NOD2 in inflammation outside the central nervous system (CNS) is well-established, especially in the gastrointestinal system, its expression and function in the brain remain poorly defined. Previous genetic studies suggest a link between NOD2 and neurological and psychiatric conditions, including stroke, Parkinson’s disease, and schizophrenia. However, information regarding NOD2 expression, localization, and function in the CNS is limited. In this work, we investigated NOD2 expression, localization, and regulation …

"I'M Not Having Fun Anymore": A Qualitative Analysis Of Gender And Harassment In Bars And Clubs, Phoebe Marie Jackson

Dissertations

Sexual harassment, while often spoken about in hushed tones or ignored altogether, happens frequently and often loudly. 66 percent of women who have experienced sexual harassment report that the harassment took place in a public space, such as work, school, or on the street (Kearl, 2018). Harassment is not discreet, but rather normalized, and those who experience it are expected to brush it off or take it in their stride. However, such harassment and subsequent dehumanization has a deteriorating effect on the mental well-being of those affected (Graham et. al., 2016). This study aims to hone in on the effect …

Ultramodern Racism: A Critical Discourse Analysis Of The Impact Of Anti-Crt Legislation On Us History Curriculums, Amelia Gernand

Dissertations

In the wake of Donald Trump’s failed 2020 bid for a second presidential term, there was a surge in anti-CRT legislation targeting how issues of race and racism could be taught in public school curricula. While proponents claim that anti-CRT laws will protect students of all races from discrimination, curriculums have historically been used as a tool by those with symbolic power to legitimize white supremacy and perpetuate anti-Black and color-evasive racism. Two states--Florida and Arkansas--recently enacted anti-CRT legislation in addition to Black history mandates. While legislators in these two states claim that their goal is to expand the teaching …

The Forced Sterilization Of Quechua-Speaking Women In Peru: The Role Of Epistemic Injustice In The Perpetration Of Genocide, Geraldine Diaz

Dissertations

The forced sterilization of Quechua-speaking women in Peru from 1996 to 2000 represents a case of genocide in which the state as an epistemic agent has a fundamental role. Although the systematic sterilization was carried out under the guise of a family planning program, the targeting of these women provides strong circumstantial evidence of genocidal intent. According to the testimonies of these women, medical staff, acting on behalf of the government, performed tubal ligation procedures through coercion, threats, lies, bribery, manipulation, and other tactics where the state intentionally withheld information, misinformed women, and failed to obtain proper consent. This research …

Dissertations

The study focuses on examining the influence of person-of-the-therapist or self-of-the-therapist training on therapists’ self-reports of self-awareness (as a conscious awareness of one’s internal states and interactions with others) and self-efficacy (perceived beliefs in personal capabilities to perform in ways that give control over events that affect their lives) at the novice professional stage of their career. The study will examine the experiences reported by mental health providers actively providing clinical care by utilizing a survey design focusing on person of the therapist connecting through alumni lists and online solicitation. This research adds to the current literature by using a …

What Works In Telehealth Play Therapy? An Appreciative Heuristic Inquiry, Veronica Ann Ball

Dissertations

With the onset of coronavirus disease 2019 (COVID-19) in the United States in March 2020 (World Health Organization, 2020), professional counselors providing traditional in-person play therapy found themselves in a quandary regarding the delivery of services during a global pandemic (Evans, 2022; Mitchell, 2020; Whaibeh et al., 2020). Online counseling proffered a means to prevent the disruption of services, respond to the need for emerging counseling services, and comply with social restrictions (Evans, 2022). Prior to the pandemic, telehealth play therapy was used sparingly (Haslam & Harris, 2011; Smith et al., 2021), and many child-serving mental health professionals lacked training …

What About The Children? An Exploration Of Family Counselors' Play Therapy Training And Preparedness To Integrate Children Into Family Counseling, Patricia J. Walker Monical

Dissertations

Children are an important part of families, yet family counselor education programs often do not incorporate training for including children in family counseling. At some point in their careers, family counselors and therapists will encounter clients who have children 3–12 years old. The problem is that since these professionals often receive little to no training in play therapy and thus do not typically include young children in family therapy, these younger family members are often overlooked. Research has confirmed that, due to a lack of sufficient training and supervision in play therapy, many family therapists report feeling unprepared to work …

Exploring Undergraduate Understanding And Learning Of Catholic Social Teaching In Catholic Higher Education, Kenny Van Tilburg

Dissertations

Since the Second Vatican Council in the mid-1960s, Catholic higher education (CHE) has wrestled with its Catholic identity in a changing landscape and changing world (Gallin, 1996, 2000; Gleason, 1995; Morey & Piderit, 2006). A big component of this identity-recognition process is the continued evolution and inclusion of Catholic social teaching (CST) in the educational approach of CHE. Despite its importance, much evidence has suggested CST is underwhelmingly present in the education of contemporary CHE (Beyer, 2021; Galligan-Stierle, 2014; Hudson et al., 2018; Nickerson & Dammer, 2018; Reed-Bouley, 2016; Sullivan & Pagnucco, 2014; United States Conference of Catholic Bishops [USCCB], …
