The research question was, How do Hispanic women in aerospace-internship programs navigate the intersection of cultural identity and professional development as they transition from academic science, technology, engineering, and mathematics (STEM) programs to aerospace careers, and what role does culturally responsive mentoring play in supporting their retention?

Using Anzaldúa’s nepantla concept, Duncan-Andrade’s critical-hope theory, and Ladson-Billings’ culturally relevant pedagogy as theoretical frameworks, in this study, I employed semistructured …

Cyberbullying Victimization And Suicide Behavior: The Roles Of Social Anxiety And Body-Related Comparison Among Young Latina Adults, Monica Elena Ochoa

Theses and Dissertations

Suicide behavior rates have increased over the years in the United States among Latinas and adolescents/young adults. Previous research has identified relationships between various body-related concerns, (e.g., body dissatisfaction, appearance comparison, and body shame) cyberbullying, social anxiety, and suicidal ideation, yet minimal research has examined the relationship of these factors and how they interrelate to explain suicide risk in Latina young adults. This study investigated whether body dissatisfaction, appearance comparison, and body shame had indirect effects on suicide behaviors through the interaction of cyberbullying victimization in 194 Latina college students. The results of this study found that cyberbullying victimization mediated …

La reimaginación se plantea como una forma de intervenir estratégicamente en los relatos heredados mediante operaciones como la deconstrucción, la excavación psicológica y la reubicación cultural. El estudio aborda, además, subgéneros del …

An Evaluation Of Noncontingent Reinforcement And Additional Treatment Components In The Treatment Of Stereotypic Behavior, Stephanie Nicole Brand

Theses and Dissertations

Individuals with autism often engage in stereotypic behavior that competes with learning and social skills. Behavior analytic treatment may be implemented to reduce stereotypy. Noncontingent reinforcement (NCR) is one treatment that is often effective to reduce stereotypy. However, literature suggests that the use of NCR is contraindicated in some circumstances, as it may compete with the acquisition of new skills or may increase subsequent persistence of stereotypy. This research was designed to expand our knowledge of potential limitations of NCR when combined with other treatments. Study one examined persistence of stereotypy following treatment with NCR with and without response blocking. …

Conflict Management: Values-Based Training Effects On Shifts In Strategy Preference Among Formerly Incarcerated Individuals, Candace Renae Fay

Theses and Dissertations

Problem-solving refers to a behavior evoked by a problem in which the behaver manipulates, supplements, and consequently, generates discriminative stimuli (SD) that they subsequently respond to (Donahoe & Palmer, 2004; Skinner, 1957, 1968). The use of problem-solving when faced with interpersonal conflict reflects pro-social behavior patterns, while providing a learning opportunity for identifying relevant variables and contingencies, and possible reductions of extended conflict or escalation in anti-social behavior patterns. Patterns of preference can be identified following multiple opportunities, given an array of options, resulting in consistency of choice responses (Martin, 2006). When less prosocial (avoiding, yielding), or antisocial (forcing) conflict …

The Relationship Between Perceived Transactional Distance, Cultural Values, And Online Instruction Among Higher Education Students: A Quantitative Analysis, Judith Kay Guetzow

Theses and Dissertations

This quantitative survey research study examines potential correlations and influences on the learning of students enrolled in online classes at the University of Texas Rio Grande Valley (UTRGV). The study specifically investigates whether transactional distance (TD) as conceptualized in Michael G. Moore’s Transactional Distance Theory (TDT), and cultural values such as power distance (PD), uncertainty avoidance (UA), and collectivism (CO) as defined in Geert Hofstede’s Cultural Dimensions Theory, are associated with, and impact the learning experiences of online students. The analysis primarily centers on students’ perceived transactional distance and their self-reported cultural orientations.

Investigating The Impacts Of Facial Gestures On Global Participants’ Perception Of The Speaker, Perception Of The Message, Emotional Responses, And Engagement During Video Conferencing, Hanan Mohammed Alghamdi

Theses and Dissertations

Facial expressions play a crucial role in shaping communication and emotional understanding during virtual interactions. This study investigated how facial expressions influence participants’ perceptions of the speaker, perceptions of the message, emotional responses, and engagement during video conferencing across diverse cultural contexts. A hybrid experimental design was implemented using self-administered questionnaires to collect quantitative data and examine cause-and-effect relationships. Participants were randomly assigned to one of three facial-expression conditions Positive (smiling and joyful), Negative (angry or nervous), or Neutral (expressionless) and viewed speakers representing three ethnic backgrounds: White American, Black American, and Middle Eastern. Using a seven-point semantic differential scale, …

Life After Prison: Exploring Gendered Differences In The Impact Of Social Support On The Ease Of Reintegration For Previously Incarcerated Men And Women, Joy Ferdinand

Theses and Dissertations

Successful reintegration into society remains a significant challenge for formerly incarcerated individuals, particularly in securing stable housing and employment. This study examines the gendered impact of social support on reintegration outcomes, specifically assessing how peer instrumental support, familial instrumental support, and familial emotional support influence housing stability and employment within three months of release. Using data from the Serious and Violent Offender Reentry Initiative (SVORI), this study employs logistic regression models to explore whether gender moderates the relationship between social support and reentry success. Findings indicate that peer instrumental support significantly affects housing stability, but its impact varies by gender. …

The Role Of Differentiation Of Self And Self-Construal On Satisfaction With Life And Psychological Well-Being In A Brazilian Sample, Kavya Dhaipulle

Theses and Dissertations

The present study intended to confirm the self-construal dimensional model and to examine the cross-cultural applicability of Bowen’s Family Systems theory in the Brazilian context. Bowen’s concept of Differentiation of Self (DoS) has gathered substantial empirical evidence for its association with well-being; however, only a few studies have examined these constructs within Latin American cultures, including Brazil. Recent studies have indicated that independent and interdependent self-construal coexist in many Latin American cultures, such as Brazil. Therefore, the current study examined how the unique blend of independent and interdependent values in Brazilian culture relates to their DoS, overall psychological well-being, and …

​​​How Do Working Conditions Effect Teacher Job Satisfaction And Intention To Stay: Retaining Special Education Teachers​, Alyssa Michelle Raygoza

Theses and Dissertations

Teacher retention remains a leading area of focus in the United States. Recent research efforts have examined the effects of specific work-related experiences on teacher retention. In comparison to teaching in a general education classroom, special education teachers often face increased levels of job demands that can influence the ways in which existing resources may or may not balance out such challenges. The study is grounded in the Job Demands-Resources (JD-R) Model, a theoretical framework that has been used widely in both occupational and, more recently, educational research focusing on the specific demands and resources situated within teacher working conditions. …

Influence Of School Climate On Comprehensive School Behavioral Health Effectiveness, Halle Rose Singer

Theses and Dissertations

Youth are experiencing a sharp rise in mental health concerns, which have reached critical levels. Schools have emerged as a key setting for delivering mental health services due to their accessibility, familiarity, and capacity to reach diverse populations. Comprehensive School Behavioral Health (CSBH) systems offer a multi-tiered, evidence-based framework for supporting the mental health of all students. However, the success of CSBH interventions varies across schools presumably indicating that systemic or school level factors, like school climate, may influence youth mental health outcomes. In this study, I investigate how school-level factors, specifically student-perceived school climate, influence the mental health outcomes …

Cultural Diagnosis And The Monsters Of Victorian England, Victoria Elizabeth Kuykendall

Theses and Dissertations

This dissertation examines the representation of invisible disability and neurodivergence in nineteenth-century British literature, arguing that literary texts both reflect and shape cultural understandings of disability. While much scholarship has focused on visible or physical impairments in Victorian fiction, comparatively little attention has been given to characters whose behaviors, emotions, or identities align with what today might be described as neurodivergence.

Drawing on Disability Studies, Mad Studies, and cultural theory, I propose the concept of cultural Diagnosis as a framework for analyzing how fictional characters become “Diagnosable” within both their historical and contemporary cultural contexts. Through close readings of Arthur …

The speech task involved the repetition of sentences that included specific vowel targets, and the non-speech task was a visuomotor pursuit rotor task which required tracking a moving target on a computer. The participants were twenty young adults between the ages of 18 and 30 and twenty older adults above the age of 60. They performed each task on its own and both tasks concurrently, prioritizing one or the other task. Audio recordings were analyzed with software to extract …

Creativity In Large Language Models, Robert Kenneth Morain

Theses and Dissertations

As artificial intelligence systems approach human-level performance across a wide variety of domains, creative domains remain a critical yet underexplored area of research. Unlike traditional AI tasks with well-defined objectives, creative tasks rely on inherently subjective measures, making them particularly challenging for machines that lack human experiential context. This dissertation establishes the fundamental importance of creativity in AI systems and presents methods for improving and evaluating the creative capabilities of LLMs on the pathway toward AGI. This work addresses and examines key limitations in current LLM creativity through model innovations, development frameworks, and comparative studies. The dissertation develops novel architectural …

Examining Choices Of Sarcastic Responses In Dialogue With Virtual Interlocutors, Samantha Langley

Theses and Dissertations

We report the results from three experiments examining people’s preferences for using sarcasm in conversation as a function of: 1. whether their interlocutor uses sarcasm during the conversation; 2. Their knowledge about whether the interlocutor has used sarcasm in a previous conversation; 3. The presence of prosodical and visual cues for interlocutors’ sarcasm. In each experiment, participants took part in two conversations, and we manipulated whether the interlocutors were sincere or sarcastic and whether they remained the same or changed from one conversation to the next. Experiment one used written conversations and experiment two and three used pre-recorded video clips …

Adapting To Inflationary Pressures: Household Coping Strategies In Urban Egypt (2016– 2025), Mohamed Mohamed Ashraf Kamal

Theses and Dissertations

Over the past decade, Egypt has faced persistent economic challenges including repeated currency devaluations, high inflation rates, subsidy reforms such as the gradual reduction of food and energy subsidies, and the ripple effects of global crises that have significantly impacted household well-being, especially in urban areas. These pressures have eroded purchasing power and heightened food insecurity, especially among low- and middle-income families. Although substantial attention has been paid to macroeconomic indicators, there remains a critical gap in understanding how households adapt on a daily basis to manage financial stress and sustain their livelihoods. This inquiry is especially timely, as household …

The Moderating Effects Of Community Involvement On The Association Between Witnessed Community Violence And Mental Health Outcomes Among Black Adolescents, Curtisha Tamara Shacklewood

Theses and Dissertations

Black youth and adolescents are at a disproportionately high risk for experiencing community violence exposure (CVE) and the potential influence it may have on psychological functioning. Research posits that Black youth who experience community violence are at a significantly higher risk of experiencing elevated internalizing symptoms (e.g., depression) and externalizing symptoms (e.g., delinquency). Previous research has utilized the ecological model to investigate interpersonal protective factors that potentially buffer the effects of CVE, including parental support and family characteristics. However, there is little research that explores community-level factors, such as community activities (e.g., youth activities and parental perception of collective efficacy) …

Leveraging After School Programs As Resources To Support Adolescent Health And Wellbeing Within Underserved Communities: A Qualitative Study, Olivia Staples

Theses and Dissertations

Over the past decade, youth have shown a consistent rise in stress, major depression, anxiety, and suicide, with underserved youth (low-income, minoritized communities) at greatest risk of exposure to chronic stress, related outcomes, and less access to health services (APA, 2017). Afterschool programs (ASPs), which serve as important resources in underserved communities, can be a critical support for youth health and well-being (Afterschool Alliance, 2019). However, few studies have examined ways in which ASPs address the challenges underserved youth face across their ecosystem to promote youth resilience (Jones & Deutsch, 2011). Using qualitative interview data from staff and youth across …

Inspiring Girls To Fill The Blank Space In Stem: The Impact Of An After-School Coding And Robotics Club On Elementary Female Students' Engagement And Self-Efficacy In Computer Science, Lisa Guenther Wilbanks

Theses and Dissertations

The purpose of this action research was to describe how participation in an after-school coding and robotics program influenced elementary female students’ engagement and self-efficacy in computer science. According to a 2023 report from the National Science Foundation, in 2020 women earned only 21% of computer science degrees and 24% of engineering undergraduate degrees in the United States. As two of the fastest growing fields, the lack of female perspectives and experiences will continue to limit innovation in these areas. Studies show that gender gaps in engagement and self-efficacy in STEM begin long before students enter college and the workforce, …

Ai-Driven Autonomous Manufacturing: A Novel Taxonomy, Vision-Guided Planning, And Diversity-Aware Active Learning Frameworks, Ibrahim Yousif

Theses and Dissertations

Manufacturers face two opposing challenges: the escalating demand for customized products and the pressure to reduce lead times. Current manufacturing equipment, although reliable, operates at the limits of its technology and lacks adaptability to dynamic environments. This trade-off has been described as the optimal degree of automation, a threshold beyond which further automation incurs more cost than benefit. Smart manufacturing has introduced adaptive, data-driven systems, but many deployments still lack the contextual adaptability and autonomous decision-making required to handle unplanned disruptions. This underscores the need for intelligent, autonomous systems capable of real-time adaptation without costly reconfiguration, minimizing human intervention during …

Hearing The Difference: Just Intonation Techniques Utilizing Distortion Product Otoacoustic Emissions In Viola Performance, Calj Green Umezono

Theses and Dissertations

Difference tones, also known as distortion product otoacoustic emissions, are the result of active phenomena in the human cochlea during the conversion of sound waves into bioelectrical signals. Difference tones make it possible to explore alternative musical tuning systems beyond the twelve-tone, equally tempered regime. Musicians have investigated difference tones since the 18th Century in Euro-American musical contexts, but their application has so far been limited in scope. Advances in science, technology, and music theory from the late 19th Century through the early 21st Century have given present-day violists the opportunity to more fully understand the virtues of difference tones …

Media use has become an integral part of everyday life. It has risen dramatically over the past century with the advent of television, computers, and digital platforms, and more recently, it has been characterized by individuals using multiple devices simultaneously (Bushman & Anderson, 2001; Nielsen Media Research, 1998; Rideout & Robb, 2019, 2021). Media multitasking (MMT) has been linked to cognitive control challenges and attentional difficulties. This study examined EEG workload (Fz theta/Pz alpha ratio), survey accuracy, and ADHD traits (ASRS v1.1) in 33 adult participants across baseline and single-versus dual-media conditions. Results indicated that mental workload was significantly higher …

Predictors Of Outpatient Follow-Up Attendance And Subsequent Psychiatric Readmission, Sandra J. Beltran

Theses and Dissertations

Psychiatric readmissions remain a persistent challenge in mental health care, often reflecting gaps in continuity of treatment following discharge. The Agency for Healthcare Research and Quality (2019) indicated that a key component in preventing inpatient readmission is adequate outpatient care following discharge. Moreover, early attendance in outpatient follow-up visits is associated with improved patient outcomes (Boston Medical Center, 2022). Various predictors are associated with engagement in outpatient services, such as age, medication compliance, and socioeconomic variables (Carson et al., 2014; Li et al., 2005; Marino et al., 2016; Stubbs et al., 2024).

The present study sought to determine whether psychiatric …

Parent Perspectives On Contemporary Adolescent Concerns, Allyson Worthy

Theses and Dissertations

Adolescence is a critical developmental period that marks the transition between childhood and adulthood. Psychopathology is known to emerge during this time, in which many internalizing and externalizing disorders have their onset. The assessment of adolescent psychopathology involves use of questionnaire measures to obtain perspectives from the adolescent themselves, their parents, and their teachers. Parents have been found to be especially important informants of adolescent functioning. With new challenges that arise for present-day adolescents (e.g., social media use), parents can provide insight into the different areas that need to be evaluated when assessing domains of contemporary adolescents’ development and psychopathology. …

Multilateral Organizations And Health Emergency Management During Crisis: The Case Study Of The World Health Organization During Covid-19 Pandemic, Aya Helmy Hamada
