Manned Exploration Of Satellites Of The Outer Planets: An Analysis Of Current Technologies And A Discussion Of Advancements Required, Joshua Carson Meador

Theses and Dissertations

The Solar System’s outer planets have many satellites, some of which are known to be the most likely places to find extraterrestrial life in our celestial backyard. Multiple scientific missions have been sent to glean information from these satellites, yet the possibility of a manned expedition has long been exclusive to science fiction stories. This paper intends to collect and analyze the current state of space travel technology to explore the feasibility of such a mission with modern technology and to discuss which future advancements should be the focal point for making such missions a reality. To begin, data on …

Unlocking Innovation: The Impact Of Psychological Safety, Organizational Structure, And Rigidity On The Pursuit Of Innovation Within The Firm, Robert Kyle Rudd

Theses and Dissertations

Innovation is often a competitive advantage generator, growth, and organizational success. However, there is relatively little empirical literature that describes how organizations may be designed such that employees also feel significant freedom to innovate. This dissertation investigates the role of psychological safety and organizational design conditions, perceived organizational structure and perceived organizational rigidity as joint predictors of perceived freedom to innovate (PFTI) of employees.

The quantitative, cross-sectional survey design was used to gather data of 425 full-time U.S.-based employees who were recruited through CloudResearch. Respondents undertook validated scales of psychological safety, perceived organizational structure, perceived organizational rigidity and perceived freedom …

Teacher Narratives Of Curriculum Implementation In Bilingual Education: A Vygotskian Analysis, Jose F. Orozco

Theses and Dissertations

This narrative inquiry explores bilingual educators' experiences implementing the Amplify Reading curriculum in a diverse, Title I-funded urban district. As schools adopt standardized curricula, tensions emerge between monolingual standards and the needs of bilingual students. Using a Vygotskian framework with Cultural-Historical Activity Theory (CHAT) and Knowledge Structures (KS), the study examines how teachers navigate systemic contradictions and how these tensions influence their professional identities.

Using an interpretivist approach, data were collected via semi-structured interviews, a focus group, and a researcher’s journal from six experienced bilingual educators. Thematic analysis reveals profound structural fractures within the activity system: a primary contradiction between …

By considering their professional histories, backgrounds, and cultural perspectives, this study examined how these experiences shaped participants’ perceptions of the current state of deaf education.

Using a qualitative narrative research design, three participants with experience working in high school deaf education settings were interviewed individually and later participated in a focus group discussion. The interviews and focus group centered on participants’ perspectives regarding key issues in deaf …

Voices From The Classroom: Elementary Teachers’ Perspectives On Teaching And Learning During The Covid-19 Pandemic – A Case Study And Autoethnography, Alicia Lopez-Hernandez

Theses and Dissertations

Guided by constructivist learning theory and sociocultural theory, this qualitative case study and autoethnography examines how bilingual educators constructed knowledge, adapted instructional practices, and utilized mediational tools within face-to-face, online and hybrid learning environments. These frameworks informed the study’s design, data analysis, and interpretation of findings related to pedagogy, technology integration, and student engagement. Data was collected through semi-structured interviews, naturalistic observations, and autoethnographic reflective journaling.

Exploring Servingness Through Pedagogy: A Critical Case Study Of An Hispanic Serving Institution, Yemin Sánchez

Theses and Dissertations

This critical ethnographic case study advances current understandings of what it means to teach at an Hispanic Serving Institution (HSI) and how faculty enact servingness within an HSI enrolling high indices of Latin@/Hispanic students. Drawing on decolonial, culturally sustaining and liberatory pedagogical frameworks, this study interrogates how constructs such as Hispanic, Latin@/Latinx, or coloniality shape the pedagogical conditions under which faculty operate. Using pláticas with ten faculty members, this research study demonstrates servingness is not a technique or an institutional designation, instead, it is a fluid and deeply humanizing ecology with five mutually reinforcing dimensions: Servingness as Relational Praxis, Servingness …

Use Of Complementizer That Among English-Spanish Bilinguals, Aziz Abraham Quenun

Theses and Dissertations

Languages vary in how they signal the presence of an embedded clause. Both English and Spanish use what are termed complementizers—that in English and que in Spanish—but in English, the complementizer is often optional while in Spanish, it is generally required. This thesis tested if the presence of que in a Spanish sentence could induce a bilingual speaker to insert a previously omitted that into an English sentence using a syntactic priming task. The results of these trials showed that this was the case, finding a statistically significant priming effect, supporting the idea that syntax is cognitively shared across languages …

Academic Anxiety, Anxiety Sensitivity, And General Mental Health In Collegiate Student-Athletes, Finley Gabrielle Elkins Sims

Theses and Dissertations

Collegiate athletes’ mental health is on the decline, and they have unique experiences that can influence the prevalence of mental health struggles. This study examined academic anxiety, comorbid forms of anxiety, and predicting factors in 187 collegiate student-athletes across 29 U.S. colleges. Athletes had significantly higher levels of academic anxiety and general anxiety compared to a college nonathlete population. There were significant gender differences in athletes, with females having greater levels of anxiety sensitivity, academic anxiety, sport anxiety, general anxiety, depression, and a history of depression than male athletes. Gender, history of depression, anxiety sensitivity, and depression were significant predictors …

Intersecting Identities, Social Support, Multiple-Minority Stress, And Health Outcomes Among Latinx Lgbtq+ Adults, Amanda Lamas

Theses and Dissertations

Latinx LGBTQ+ adults experience poor health due to exposure to intersectional discrimination; however, they also possess protective factors to cope with these stressors. This study explored the associations and interactions of identity affirmation (ethnic, American, LGBTQ+), identity outness, perceived social support, LGBT-POC microaggressions, and health among LGBTQ+ Latinx adults. Correlational analyses and regression models controlling for covariates showed that American and ethnic identity affirmation, perceived social support, and identity outness were positively associated with health, and LGBT-POC microaggressions were negatively associated with health. LGBTQ+ identity affirmation was directly correlated with mental health, but not in the regression model. Identity affirmation …

La Panza: Un Acto De Rebeldia Para Los Atravesados Y Los Que Siguen Despues / The Panza: An Act Of Rebellion For The Inbetweeners And Those Who Follow After, Abigail Guadalupe Cantu

Theses and Dissertations

Our ancestors, family members, and ourselves that live in the borderlands have embodied knowledge, and/or an innate intuition that comes from the pit of our soul, particularly from our “panza”; hence, the creation of a panza consciousness as the focus for my thesis. I’m trying to “rediscover” the embodied knowledge that has been taken from us and how we can learn to harness these forms of knowledge into a societal shift ( i.e. how we interact with others, how we see our bodies, how see the creation of knowledge, and how we see the world). Although, Eurocentric ideals sought to …

Investigating Pre-Service Teachers’ Readiness For Early Reading Instruction: A Mixed Methods Study Of Quantified Knowledge In Phonemic Awareness And Lived Experiences, Kristin Morgan

Theses and Dissertations

This dissertation examines the lived experiences of pre-service teachers as they develop their knowledge and instruction skills during a three-week module within their first literacy course in a teacher preparation program. Literacy courses play an important role in equipping pre-service teachers with the knowledge and skills necessary to promote reading development. Research suggests that phonemic awareness is a crucial skill that predicts later reading achievement; however, many teachers lack the necessary experience and knowledge. This gap raises concerns about teacher preparation programs and how pre-service teachers learn. Guided by Vygotsky’s sociocultural theory, this sequential explanatory mixed-methods study sought to understand …

"We're Not The Exception. We're The Expectation.": Black Undergraduate Men Disrupting The Dominant Discourse Through Narratives Of Persistence And Belonging At A Predominantly White Institution, Michael M. Mack

Electronic Theses and Dissertations

Black undergraduate men (BUM) at predominantly White institutions (PWIs) have often been portrayed through deficit-oriented narratives that emphasize barriers and premature departure while minimizing the voices of those who persist and cultivate belonging. The researcher addressed this problem by examining how BUM at a private PWI narrated their persistence and belonging, and how their narratives disrupted the dominant discourse about Black men in higher education. Literature regarding BUM at PWIs has too often centered obstacles and attrition while overlooking the voices, strategies, and experiences of BUM who persist. Therefore, Black men’s narratives were solicited to better understand what enabled persistence …

Senior-Level Administrators’ Perceptions Of Deliberately Developmental Organization Principles And Employee Retention At Historically Black Colleges And Universities (Hbcus), Caprinia L. Taylor

Electronic Theses and Dissertations

Historically Black colleges and universities (HBCUs) have faced persistent challenges retaining qualified faculty and staff, threatening the environments they are uniquely positioned to create. High turnover, limited professional development, and inadequate support undermine employee well-being and student outcomes. This qualitative phenomenological study explored senior-level administrators’ perceptions of deliberately developmental organization (DDO) principles and their relevance to employee retention at HBCUs. Guided by DDO and organizational culture theory, the study examined how leadership practices, professional development, psychological safety, and organizational culture intersect with retention and belonging. Data were collected through semistructured interviews with participants across diverse HBCU contexts. Participants were selected …

Investigating Racial And Ethnic Differences In Help-Seeking Recommendations And Intentions For Posttraumatic Stress Symptoms And Symptom Clusters, Josselyn Yanisbeth Telule

Master's Theses

Racially and ethnically minoritized (REM) communities experience disproportionate exposure to adverse events, including discrimination, socioeconomic disparities, justice system involvement, and limited access to healthcare. These inequities increase the likelihood of experiencing potentially traumatic events (PTEs) and developing trauma-related mental health concerns such as posttraumatic stress symptoms (PTSS). Despite this elevated risk, REM populations consistently underutilize mental health services. Although several explanations have been proposed—including differences in symptom recognition, perceived need for care, cultural values, mental health literacy, and preferred sources of support—less research has examined racial and ethnic differences in help-seeking intentions (HSI) and help-seeking recommendations (HSR), particularly in response …

Examining The Interactive Effects Of Time Perspective And Life History On Decision-Making Patterns Among College Students: A Modified Replication Of Griskevicius Et Al. (2011b), Cameron M. Robins

Master's Theses

Griskevicius and colleagues (2011b) demonstrated decision-making patterns consistent with life history theory, called life history strategies, using an experimental design in which they randomly assigned college students to read one of two texts. The experimental condition was designed to trigger a feeling of heightened awareness of one’s own mortality, called mortality salience. Participants in this condition exhibited patterns of risk-taking and delay discounting on the outcome measures that were related to their childhood socioeconomic status (SES), one of the first demonstrations of life history strategies in an experimental setting.

However, multiple attempts at replication have failed to show similar results. …

The Illusion Of Absence, Abraham K. Ali

Department of English: Dissertations, Theses, and Student Research

The Illusion of Absence is a collection of thirty poems with a critical introduction that examines the poetic legacy of paternal absence and the reconfiguration of family in Africa and diasporic narratives. I grew up in Nigeria without my father. His absence has shaped my understanding of love, silence, manhood, and home. This manuscript is an exploration of the lasting legacy of my father’s absence and its place within an exploration of masculinity within the broader context of the African and diasporic experience. My mother became the focal point within the home as she brought cohesion and unity within the …

Redefining The Mother Wound: Marianism, The Church, And Communal Mothering In Las Madres: Latinas In The Heartland Who Led Their Family To Success, Maria R. Loya-Pérez

Department of English: Dissertations, Theses, and Student Research

This thesis reconsiders the restrictive role assigned to Mexican mothers that is perpetuated by the Church and Marianism, and how those restrictions are liberated by communal mothering. In examining how a Mexican mother is expected to act based on cultural expectations, I analyze the stories of three real mothers from the familial autobiography Las Madres: Latinas in the Heartland Who Led Their Family to Success. I analyze three mothers, the matriarch Candelaria, her daughter Rafaela, and her daughter Irene to better understand how the Church and Marianism has restricted them based on the experiences of Candelaria. These restrictions when placed …

Aligning Care To Cognitive Style: A 4-Question Framework For Patient-Centered Dermatology Visits, Elise Lau, Jeremy Haskins, Vishnu Palaniappan, Kumar Nadhan

Student Publications

Objective: To improve patient-centered dermatology care by identifying how patients prefer to approach medical decision-making and structuring their visit, using a brief 4-question intake survey focused on cognitive style.

Methods: New patients at 2 dermatology clinics within the California Skin Institute completed a multiple-choice intake questionnaire before their first visit. The survey asked patients how many concerns they wanted to address, how much guidance they preferred in selecting treatment, whether they prioritized diagnosis or treatment during the visit, and their expected timeline for results. Associations between patient responses and demographics (sex, age, chief complaint) were analyzed using χ2 tests.

Results: …

Callie Bowland - Various Works, Callie E. Bowland

Professional Practices (ART 399)

My ceramic works explore stress, masking, and how they affect the body over time, in addition to what can be considered the true self, and how society reacts to it. They all feature an element of abstract, twisting flesh.

Reliquary uses it as a very literal interpretation of inner beauty, turning flesh and bone into an ornate vessel, playing with the parallel of the human body as a vessel for the mind. It also poses the question of what makes up a person, by contrasting the corporeal flesh and bone with a mask- like face–are we the physical body itself, …

Detecting Doubt In Reflective Learning: A Learning Analytics Study With Large And Small Language Models, Eng Lieh Ouh, Kar Way Tan, Siaw Ling Lo, Yuhao Zhang

Research Collection School Of Computing and Information Systems

Reflective learning enhances understanding, especially when instructors promptly address difficulties raised in student reflections. Automated doubt detection can reduce time for instructors, yet existing classification approaches take substantial time for manual annotation and model training. This paper investigates whether large and small language models (LLMs, SLMs) can automate doubt detection without time-consuming training. Using a dataset of anonymized student reflections, we evaluate zeroshot, few-shot prompting, and multi-step reasoning against prior supervised classification baselines. We show that LLMs (GPT-4o, Claude-4, Gemini-2.5) surpass earlier F1 scores without prompting, while prompting further improves their performance. However, using proprietary LLMs can raise cost and …

Reward Representation Learning, Gregory M. Hyde

Dartmouth College Ph.D Dissertations

The \emph{Markov decision process} (MDP) has long served as the canonical model for sequential decision-making. However, it assumes that the reward function is Markov with respect to a given state representation---an assumption that often does not hold in practice. Instead, agents typically only perceive streams of observations and actions and must infer the latent structure according to which reward unfolds over time. From this perspective, reward prediction is initially non-Markov, reflecting a mismatch between the agent's current representation and the underlying structure of the environment.

In this thesis, we advance the view that reward is not simply a signal to …

Girl Grammar: A Syntactic And Pragmatic Analysis Of Girl And Miss Girl, Evelyn A. Powers

Senior Honors Papers / Undergraduate Theses

Based on observation, personal interaction, and informal interviews/linguistic judgements, this thesis presents the unique and asymmetrical grammaticality patterns of the terms Girl and Miss Girl. To account for these asymmetries, I provide a syntactic framework rooted in Minimalism and Rizzi’s (1997) expanded CP hypothesis, alongside a pragmatic explanation based on Barros and Frank’s (2023) attentional maintenance and attentional shift paradigm.

Miss Girl behaves as a typical R-expression when used as a 3rd person subject, but Girl has a very restricted distribution, inconsistent with either R-expressions or pronouns (it is acceptable as the subject of a main clause, ungrammatical in object …

Engineering Translational Biosensing Tools Forparkinson’S Disease, Mercedes Terry

Theses and Dissertations

Parkinson’s disease is a progressive neurodegenerative disorder characterized by motor dysfunction and early cognitive decline. Diagnosis and monitoring remain largely symptom-driven, relying on clinical scales that capture disease only after significant neurodegeneration has occurred. These assessments are inherently subjective, episodic, and insensitive to early-stage pathology, limiting both timely diagnosis and the ability to track disease progression or therapeutic response. The lack of objective, quantitative biomarkers for both molecular pathology and cognitive impairment remains a major barrier to advancing precision medicine approaches in Parkinson’s disease. This dissertation approaches Parkinson’s disease from two complementary fronts: molecular detection of alpha-synuclein pathology and quantitative …

Algorithmic Resilience Memory: Designing Agentic Ai Systems For Organizational Learning And Climate-Crisis Adaptation, Harsha Sammangi, Aditya Jagatha, Navyasri Maddukuri

Research & Publications

Climate disruption has become a persistent organizational condition rather than an episodic event, yet most information systems designed to support organizational resilience treat each disruption as an isolated incident. Existing digital resilience platforms, disaster recovery systems, and AI-driven decision support tools lack the capacity to accumulate, encode, and reuse organizational knowledge across successive climate-related crises. This paper introduces Algorithmic Resilience Memory (ARM), a novel IS construct defined as an AI-enabled organizational capability through which agentic AI systems sense climate-related disruptions, encode prior organizational responses, preserve decision rationale, generate contextually adaptive recommendations, and reconfigure future actions through structured outcome feedback. Drawing …

This study was an autohistoria-teoría, a type of autoethnography, where I focused on my writing process as a Pasifika researcher creating a middle- grade fiction. As the researcher, my questions delved into how I engage in writing for a majority-culture dominated publication house in a Western-world writing genre while maintaining the cultural significance of the ancient Pasifika mythologies I reproduced and recontextualized in the novel. The research site was my writing process, and the data gathered came from the variety of ways I navigated cultural stimuli specific to writing the novel. The outcome engaged with the specific way Pasifika (and …

Evaluating The Feasibility, Acceptability, And Preliminary Efficacy Of An Online Acceptance And Commitment Therapy Program To Improve Dietary Quality In Highly Stressed Adults, Francesca M. Knudsen

All Graduate Theses and Dissertations, Fall 2023 to Present

Stress can negatively affect both mental and physical health, which can increase the risk for chronic illness. When people feel stressed, they may also find it harder to make healthy food choices, which can further impact their health. Despite this, there are limited treatments designed to help people improve their dietary quality while managing stress. Acceptance and commitment therapy (ACT) is an evidence-based psychological approach that helps people respond more effectively to difficult thoughts and emotions while behaving in ways that are aligned with their personal values. This study tested whether a brief, online ACT-based program, combined with coaching phone …

A Mixed-Methods Investigation Of Physician Compassion In Consultations For Chronic Primary Pain, Sarah Daehler

All Graduate Theses and Dissertations, Fall 2023 to Present

Chronic primary pain refers to physical pain that has no apparent organic cause, cannot be explained by another condition, and has associated psychological distress or functional impairment. Chronic primary pain is common and can significantly interfere with functioning, including occupational or social functioning. Research has shown that physicians struggle to treat this population, with many physicians reporting feeling unequipped and many patients feeling that their physicians are unhelpful and dismissive. Compassion may play a key role in improving these difficult interactions. The present study analyzed a sample of 99 participants with chronic pain and 100 healthy controls to learn more …

A Survey On Digital Reading Materials And Personal Study Of Christian Religious Texts, Teancum Price

All Graduate Theses and Dissertations, Fall 2023 to Present

Religion, including reading from religious texts such as scriptures, are a part of the daily lives of many people. Modern technology has influenced the way that this religious reading takes place, but its effects have not yet been studied. Existing research of the effects of technology on reading focus on topics such as reading comprehension, but the study of religious texts is often focused on achieving a religious experience, so the existing research does not capture the whole scope of these changes. In our study, we surveyed two universities (Utah State University and Abilene Christian University) to ask individuals how …
