A Mixed Method Study Of How Teachers’ Racial Bias Relates To Student-Teacher Relationships, Tasha Marie Childs

Theses and Dissertations

Despite the important role public schools serve in students’ lives, schools are at the center of racial, socio-economic, and political divide and the epicenter of traumatic events for students who are marginalized based on their racial or ethnic identity. While ample research has demonstrated educational inequities for these students, no study to date has examined the impact of teacher racial bias on the quality of student-teacher relationships within the context of the United States (US) pre-Kindergarten through twelfth grade (PK-12) schools. A cross-sectional convergent mixed methods study was conducted to examine interpersonal racism in the classroom, and to specifically answer …

As an action researcher, I restructured the sessions to create an autonomy-supportive environment to foster educators’ leadership skills and promote authentic collaboration. Study participants had autonomy over the planning, aims, content, and facilitation of the networking sessions. A basic qualitative …

Food Insecurity In Youth And Young Adults With Diabetes: Prevalence And Association With Health Behaviors, Lauren Helene Martini

Theses and Dissertations

Given the life-long impact of diabetes(1-5), it is important to engage in behaviors that promote health and wellness to delay or prevent negative health outcomes(3, 6-10). Despite this, youth and young adults with diabetes generally do not adhere to nutritional(11-17) or physical activity(18, 19) recommendations. In households experiencing financial difficulties, especially those who are having difficulty providing sufficient food to all of its members, adhering to recommendations may be even more difficult.

The purpose of this dissertation is to better understand and contextualize food insecurity among youth and young adults (YYA) with youth-onset T1DM and T2DM. The first aim addresses …

Utilizing Deep Learning Methods In The Identification And Synthesis Of Gene Regulations, Jiandong Wang

Theses and Dissertations

Gene expression is the fundamental differentiation and development process of life. Although all cells in an organism have essentially the same DNA, cell types and activities vary due to changes in gene expression. Gene expression can be influenced by many gene regulations. RNA editing contributes to the variety of RNA and proteins by allowing single nucleotide substitution. Reverse transcription can alter the expression status of genes by inducing genetic diversity and polymorphism via novel insertions, deletions, and recombination events. Gene regulation is critical to normal development because it enables cells to respond rapidly to environmental changes. However, identifying gene regulations …

Exploring The Current Training Of Undergraduate Geology Students And Teaching Spatial Skills To Improve Student Outcomes, Ann Marie Klyce

Theses and Dissertations

Spatial skills, which represent the ability to mentally manipulate objects (Schneider & McGrew, 2012; Atit et al., 2020) have been shown to be correlated with entrance, persistence and success in STEM (Shea et al., 2001; Wai et al., 2009). Specifically, these skills have been shown to be necessary to geologists and geoscientists (Hegarty, 2014; Gagnier et al., 2016). While we recognize the importance of these skills, explicit training in them is rarely offered (NRC 2006). Consequently, cognitive scientists and discipline based education researchers have begun concerted efforts to offer training in spatial skills to improve student outcomes (e.g. Uttal et …

Negative Polar Questions And Answers In English And Korean, Keunhyung Park

Theses and Dissertations

The meaning of positive polar questions (PPQs) is relatively straightforward, so the truth conditions of PPQs can be decided easily. In contrast, the meaning of negative polar questions (NPQs) may vary, and simple yes-no answers to NPQs have seemingly unpredictable interpretations. For example, a simple yes answer to a PPQ like ‘Did you have lunch today?’ is easily interpreted as ‘I ate lunch.’ In contrast, the same yes answer to an NPQ like ‘Did you not eat lunch today?’ is not obvious out of context. Why are NPQs more ambiguous than PPQs? Based on our empirical observations of the difference …

“All The Rights Of Native Cherokees”: The Appearance Of Black People In Cherokee Society, Ayanna Goines

Theses and Dissertations

The appearance of Blacks in Native spaces affected the very structure of Indigenous lives during the forced removal of Native groups in the 1830s to the emancipation of enslaved people in the 1860s contributing to the change from a “clan-based society to a society grounded in the modern concept of rule of law” as the need to control the actions of enslaved people called for the creation of laws. Tribal courts were also used to determine whether someone was recognized and adopted into the clan. Outside of government involvement, the status of enslaved Black people was reinforced by the social …

In Her Possession And Keeping Revolutionary War Widows And The Politics Of Family Archives, 1820–1850, Riley Kathryn Sutherland

Theses and Dissertations

This thesis examines how Revolutionary War widows deployed family archives as partisan tools to claim pensions. By reconsidering the relationship between women, family archives, and state building, it challenges established understandings of revolutionary women, nineteenth-century political economy, and memory.

Revolutionary War pension laws ignited fierce partisan debates. Since pensions would require Congress to impose tariffs and assemble a fiscal bureaucracy, they were generally supported by Whigs and contested by Democrats. Knowing that, women tailored their applications to their partisan audiences. Widows often appealed to Whigs by requesting welfare, citing their poverty. But when addressing Democrats, they framed the pensions they …

Ultra-Processed Food Consumption And Risk Of Liver Cancer, Longgang Zhao

Background: Studies have shown positive associations between ultra-processed food (UPF) intake and obesity and type 2 diabetes, two risk factors for liver cancer. However, the relationship between UPF intake and liver cancer has scarcely been studied. We aimed to evaluate the association between UPF intake and the risk of liver cancer in three prospective cohorts and further explore the role of genetic predisposition to fatty liver diseases and biomarkers of liver health on modifying the association.

Methods: We used data from the Nurses’ Health Study (1986-2012), the Health Professionals Follow-up Study (1986-2012), and UK Biobank (2006-2020). Diet was assessed with …

If Not Me, Then Who? A Study Of Racial And Cultural Competence In A High School English Department, Dianna Sox

Theses and Dissertations

While the student population in U.S. public schools is diversifying, the teacher population and curriculum remain monochromatic. This action research study grew from the observation that racial and cultural content and discourse were absent from the English classrooms in my suburban high school due to a perceived lack of teacher cultural competence. Through this convergent mixed-method study, grounded in critical race theory, whiteness, and cultural competence, I sought to examine the factors that contribute to racial silence and improve teacher cultural competence in order to transform our classrooms into more racially and culturally just spaces. Surveys, independent reflections, focus group …

Supporting Lgbtq+ Ela Students Through Action Research, Nicole Mustaccio

Theses and Dissertations

English Language Arts curriculums traditionally include canonical authors such as Walt Whitman, Langston Hughes, and William Shakespeare. However, educators may not discuss the writers’ nonnormative sexuality. Moreover, educators may avoid teaching literature from a queer perspective, whether due to discomfort with LGBTQ+ terminology or because of a lack of professional development opportunities related to queer authors and queer theory.

In response to this problem of practice, I conducted this action research study to change the heteronormative culture at my high school. By providing professional development to fellow English Language Arts teachers, I sought to encourage the inclusion of LGBTQ+ authors …
