Better Days: A Minority Student’S Pathway Toward Upward Social Mobility, Brandi Nichole Anderson

Theses and Dissertations

In the United States, many minority group members have lower social status and fewer economic resources than whites. In order to advance their social status, these individuals set goals that provide them access to more economic capital, many of which include obtaining a college degree. It must also be noted, however, that minority individuals, particularly those of African American and Hispanic descent, possess many alternative types of social and cultural capital that assist them in achieving their goals (Strayhorn, 2010). This qualitative study, designed to explore the types of cultural capital minority students use to achieve their career goals, analyzes …

Teaching About Transfer: Making The Invisible Visible Through Explicit Instruction, Brittany Morgan Capps

Theses and Dissertations

Transfer of learning—or the act of adapting previously learned knowledge to new contexts—is an inherently complex process made even more mystifying by its often unconscious and therefore “invisible” occurrence. Writing, too, is a complicated activity that depends on and responds to a number of internal and external factors. Transferring writing knowledge, then, is a challenging task for writers of all experience levels. Researchers in writing studies have designed curricula intended to help college students transfer writing skills, knowledge, and practices from the writing classroom to other disciplinary and workplace contexts. Those teaching for transfer (TFT) and writing about writing (WAW) …

One Training Is Not Enough: The Effects Of A Cultural Humility Training On Mentors’ Verbal Behavior, Anna Flitner

Theses and Dissertations

Youth mentoring has been used as a method of prevention and intervention related to social, psychological, and academic outcomes for youth and adolescents, many of whom come from minoritized or low SES backgrounds. Although more diverse than other helping professions, mentors in formal programs are often white which can lead to potential cultural incongruence. To help mentors understand their own identities and work with youth of diverse backgrounds, mentoring programs have begun implementing cultural humility trainings. The current study examines the effects of a cultural humility training in mentoring. Mentors were randomly assigned to the control or training condition in …

Biobehavioral Synchrony In Autism Spectrum Disorder, Carly Glenn Moser

Theses and Dissertations

Social communication difficulties are a core feature of autism and are associated with a range of long-term consequences, including persistent deficits in pragmatic language and fewer and poorer quality friendships. High-quality synchronous interactions between parents and their children play a crucial role in children’s social functioning. The theory of biobehavioral synchrony suggests that the dyadic coordination of behavioral and physiological processes is essential to maximally benefit from a communicative exchange. Respiratory sinus arrhythmia (RSA) serves as an indicator of physiological regulation and is reduced in those with autism; thus, dyadic coordination of RSA may also be impacted and could play …

Mechanisms Of Social Stress Susceptibility And Resilience In Female Rats, Brittany Sara Pate

Theses and Dissertations

Social stress is the most common form of stress humans experience and often precipitates the onset of several comorbidities, including anxiety, depression, post-traumatic stress disorder, and cardiovascular diseases. While many individuals experience social stress and can respond, cope, and recover, some individuals are more likely to develop subsequent health conditions. Importantly, women are particularly susceptible to stress-related disorders, and the prevalence rates for these comorbid conditions are 2-3-fold higher among females compared to males. Epidemiological data suggest that cycling ovarian hormones may play a role in promoting stress susceptibility in females. Therefore, the current studies aimed to examine the effects …

Mitigating Student Anxiety In The Secondary Classroom: A Culturally Sustaining Approach, Erin Hawley Cronin

Theses and Dissertations

This study emerged in response to broader trends of increasing anxiety among schoolchildren and my own observations as a teacher. Suicide is now the second-leading cause of death for youth (Curtin et al., 2022), and anxiety is a known factor in most deaths by suicide (Nepon et al., 2010). Teachers are often the first point of contact for anxious students, but a shortage of counselors in U.S. schools and other systemic barriers prevent widespread access to counseling services (Cratty, 2019). Moreover, identity-based anxieties are often misattributed to aggression or attention-seeking, and punished in school settings, instead of recognized and supported …

Hf Radar: Shining A Light On Ocean Currents, Douglas Cahl

Theses and Dissertations

High Frequency (HF) radar systems are commonly used to estimate surface ocean currents over the coastal ocean. Their range depends on their operational frequency and low frequency systems (≤ 10 MHz) can reach distances up to 200 km from the coastline. These systems are used to estimate surface currents by measuring the phase speed of wind-driven waves and comparing the measured speed with that expected theoretically; deviations from the theoretical still-water phase speed are attributed to ocean surface currents. Although HF radar systems are considered a mature technology and the accuracy of the radar-derived surface current estimates is well studied, …

African American adolescents in the United States experience a higher prevalence of obesity as compared to their White counterparts. This health inequity presents a public health concern as consequences of weight-related chronic diseases often persist into adulthood and are increasingly problematic. As chronic stress has been found to be higher among African American youth compared to White adolescents, it presents as a potential barrier to participation for African American families in health promotion interventions. Additionally, it may be beneficial to target stress in health promotion programs as a modifiable factor in conjunction with health behaviors that may improve outcomes related …

A Bayesian Spatial Scan Statistic For Normal Data, Laasya Velamakanni

Theses and Dissertations

Scan statistics are useful methods for detecting spatial clustering. While they were initially developed to detect regions with an excess of binomial or Poisson events, spatial scan statistics have been extended to detect hotspots in other types of data including continuous data. They have many applications in different fields such as epidemiology (e.g. detecting disease outbreaks), sociology (e.g. detecting crime hotspots), and environmental health (e.g. detecting high-pollution areas). Spatial scan statistics identify a ‘most likely cluster’ and then use a likelihood ratio test to determine if this cluster is statistically significant. Spatial scan statistics have been extended to the Bayesian …

Neural Mechanisms Of Lexical Semantics: Investigating The Roles Of Hubs And Distributed Action-Perception Systems, Nicholas Andrew Riccardi

Theses and Dissertations

Understanding the meaning of words and concepts is vital for communication, forming relationships, and navigating everyday life. Loss of this knowledge through brain damage can have drastic consequences for one’s health and well-being. It is therefore important to learn how this information is organized anatomically in the brain. In this dissertation, I report a series of structural and functional neuroimaging studies in healthy adults and survivors of stroke seeking to understand how lexical semantics are represented. Specifically, I used a variety of tasks to examine the contributions of putative ‘hubs’ and distributed action-perception systems. Results indicated that damage or disruption …

Individual Differences In Perspective-Taking During Language Comprehension, Kanan Benjamin Luce

Theses and Dissertations

Previous research has found mixed results for a link between executive function and perspective-taking. One proposed reason for this is that perspective-taking during comprehension tasks may not be internally reliable. This dissertation presents two large individual differences experiments with multiple perspective-taking during comprehension and executive function measures. We aimed to see (1) whether people were consistent in their ability to take perspectives during comprehension, (2) if the typical tasks used in this area were reliable, and (3) whether executive function measures predicted perspective-taking ability. We found a lack of reliability of some of the most commonly used perspective-taking during comprehension …
