Exploring The Experiences Of Late Age-On-Arrival Multilingual Learners In Postsecondary Education, Robyn D. Ecklund

Graduate Studies Theses and Dissertations 2026

Multilingual learners (MLs) are the fastest growing population in the United States public school system (Biondi et al., 2024; Kanno & Cromley, 2013; Perez & Morrison, 2016; Varghese & Fuentes, 2020). Within this population of students, there is a subset of students that arrive in the United States during secondary school. These “late age-on-arrival” students face significant linguistic, cultural and social challenges in their pursuit of postsecondary success after high school (Kanno, 2021; Kanno & Cromley, 2013; Perez & Morrison, 2016). This interpretative phenomenological analysis sought to answer the research question: what are the lived experiences of late age-on-arrival MLs …

Detecting Error In Ai-Generated Text: The Effects Of Authorship And Word Presentation Speed, Gabriela Flores Cruz

Graduate Studies Theses and Dissertations 2026

The increased us of artificial intelligent (AI) chatbots powered by Generative Pre-trained Transformers has raised concerns about users’ ability to detect errors of AI-generated text. This dissertation examined how readers identify inconsistencies in AI-generated expository passages using the inconsistency detection paradigm from comprehension monitoring research. Across two experiments, it investigated whether perceived authorship and word presentation speed influenced inconsistency detection. Experiment 1 used a 3 (author: human, AI, no author) × 2 (inconsistency type: internal, external) between-subjects design. Perceived authorship did not significantly affect hit rates, sensitivity, or response bias. Exploratory analyses indicated that reading comprehension and working memory predicted …

Investigating The Impact Of School Leaders’ Leadership Style And Teachers’ Intrinsic Motivation For Improved Science Instruction In Elementary Schools, Leila M. Greene

Graduate Studies Theses and Dissertations 2026

A report by the National Academies of Sciences, Engineering, and Medicine, determined that 69% of U.S. elementary teachers are not prepared to teach science, especially in the areas of earth/space and physical sciences. As a result, some elementary teachers avoid teaching science. School administrators play a key role in providing a supportive environment to inspire and motivate elementary science teachers. For this reason, the study utilized the Self-Determination Theory (SDT), to examine three types of school leadership styles (Transformational, Transactional, and Laissez-Faire) and how they impact the intrinsic motivation for elementary science teachers in three areas including autonomy, competency, and …

Policy Into Practice: Exploring School Counselors' And School Psychologists' Knowledge And Sensemaking Towards The Application Of Alternative Gifted Identification Criteria For Lower Socioeconomic Students, Brittany E. Hague

Graduate Studies Theses and Dissertations 2026

Persistent underrepresentation of students from lower socioeconomic status (SES) backgrounds in Gifted education reflects long-standing structural inequities embedded in identification policies and practices. In response, many Florida school districts have adopted equity-oriented identification reforms, including universal screening, local norms, and multiple-measure approaches. However, policy equity does not automatically translate into equitable outcomes; rather, it is mediated through the interpretive work of school-based practitioners. Guided by Sensemaking Theory, this convergent mixed-methods study examines how school counselors and school psychologists construct meaning around alternative Gifted identification criteria and how their beliefs, professional judgment, and organizational contexts shape implementation. The study explores how …

Examining Teachers’ Data Usage Using The Teacher Data Use Survey, Natasha L. Hawkins

Graduate Studies Theses and Dissertations 2026

The United States spends approximately 2.7 billion dollars on classroom assessments and local exams for K-12 students (SIMBA, 2019).  However, despite this financial investment and the adoption of data-driven frameworks such as Multi-Tiered System of Support, the U.S. Department of Education found that only 55% of teachers used student data to make instructional decisions (U.S. Department of Education, 2007).  This study aims to explore the psychological and organizational factors that influence teachers’ data use when making instructional decisions.

This study used the Teacher Data Use Survey (TDUS) to investigate the extent that teachers’ use of data could be predicted by …

Strategic Signaling Or Structural Friction?: How Ai Disclosure Moderates Resource-Performance Dynamics In Hotels And Restaurants, Jaewan Heo

Graduate Studies Theses and Dissertations 2026

Artificial intelligence (AI) has become an increasingly important strategic issue in the hospitality industry. While prior research has primarily examined AI as an operational technology that improves efficiency and service delivery, less attention has been paid to how AI-related disclosures influence investor evaluations of firm resources. This dissertation investigates whether AI-related disclosures moderate the relationship between organizational resources and financial performance in publicly traded hospitality firms.

Drawing on signaling theory and the resource-based view, this study conceptualizes AI disclosures as strategic signals that shape investor perceptions of firm capabilities and future value creation. Firm-level financial data were obtained from Compustat …

Ex Vivo Sensitivity Assays With Molecular Validation To Guide Preclinical Drug Selection For Schwann Cell Tumors, Ethan W. Hass

Graduate Studies Theses and Dissertations 2026

Schwann cells are the glial cell of the peripheral nervous system. They are dependent on receptor tyrosine kinase-mediated RAS signaling, cell matrix adhesion, and cell-cell contact to proliferate during nerve development and repair. These pathways become deregulated with loss of function of the merlin tumor suppressor encoded by NF2, leading to benign tumors called schwannomas. Patients with NF2-related schwannomatosis (NF2-SWN) develop bilateral vestibular schwannomas that cause hearing loss, tinnitus, and death from brainstem compression if untreated. Severe NF2-SWN causes multiple spinal and peripheral schwannomas and neuropathic pain. Schwannomas require careful monitoring, trial and error use of repurposed anti-cancer …

This descriptive case study examines the organizational factors that affect the process of student teacher placement at K-12 classroom sites by one teacher education program. For this case study, one teacher education program in the southeastern United States was selected as the case site, and the case for this study is the process of student teacher placement. Semi-structured interviews, observation, and …

Integrated Corridor Management Framework For Severe Freeway Incidents, Sanjida Afroz Iqra

Graduate Studies Theses and Dissertations 2026

Traffic incidents are a major source of non-recurrent congestion on urban freeways, generating substantial mobility, safety, and economic impacts. Severe incidents that block multiple or all travel lanes are particularly disruptive because they degrade freeway operations and propagate congestion onto surrounding arterials. Effective Integrated Corridor Management (ICM) requires the ability to identify severe incidents, estimate their network-wide impacts, and anticipate the traffic conditions and driver behaviors that contribute to instability. This dissertation develops a data-driven ICM framework to address these challenges using real-world incident, crash, detector, and connected vehicle data from major Central Florida corridors, including I-4 and SR-417. The …

Investigating The Anti-Apoptotic Properties Of The N-Terminus Of The Chlamydia Trachomatis Effector Tarp, Kasey S. Jordan

Graduate Studies Theses and Dissertations 2026

As the most prevalent bacterial STI in the United States and leading cause of infection-related blindness worldwide, the obligate intracellular bacteria, Chlamydia trachomatis (Ct), poses a significant threat to public health. As an obligate intracellular bacteria, invasion of the host cell is a crucial step in Chlamydia’s developmental cycle. To drive invasion, Ct injects prepackaged effectors into the host cell using a T3SS. An early Chlamydial effector, translocated actin recruiting phosphoprotein, or Tarp, interacts with host cell actin to promote invasion, mediated via Tarp’s C-terminal region. Although the function of Tarp’s C-terminus is well defined, the Tarp’s N-terminus …

Teledentistry: A Path To Minimize Emergency Department Dependency For Dental Issues, Aishwarya Joshi

Graduate Studies Theses and Dissertations 2026

Teledentistry has been promoted as a strategy to minimize emergency department (ED) visits for non-traumatic dental conditions (NTDCs). However, it remains unclear whether structural readiness or temporary policy expansion drives sustained reductions in reliance on the ED. This study integrates Andersen’s Behavioral Model of Health Services Use and Diffusion of Innovation (DOI) theory to examine determinants of Medicaid NTDC ED utilization and Tele-dentistry adoption.

Andersen’s model posits that utilization is shaped by predisposing, enabling, and need factors, whereas DOI theory emphasizes structural attributes that influence adoption, including relative advantage, compatibility, complexity, trialability, and observability. Combining these frameworks allows for a …

Homoplasy Of Maxillary Orthognathism In Derived Homo, Jared Jordan

Graduate Studies Theses and Dissertations 2026

The evolution of the orthognathic condition in the genus Homo represents a monumental transition toward the facial morphology of modern humans from that of earlier hominins, but the phylogenetic positioning of this transformation remains poorly understood. This study investigated temporal trends in maxillary and mandibular prognathism in the genus Homo, and whether maxillary and mandibular shortening in East Asian H. erectus and later East Asian Middle Pleistocene Homo (e.g., Homo longi) represent independent derivations of orthognathic morphology, thereby making orthognathism a homoplasy in the genus Homo. Using a sample of roughly 109 cranial and mandibular specimens spanning …

The Impact Of Criminal Justice System Contact On Adolescents In The U.S.: Prescription Drug Misuse, Marijuana Use, Health Outcomes, And Demographic Characteristics, Fadime Gokce Karaaslan

Graduate Studies Theses and Dissertations 2026

Criminal justice system (CJS) contact remains a pervasive feature of social life in the United States, with both direct and indirect consequences for adolescents and their families. Although previous research has explored the consequences of direct CJS contact, less is known about how indirect or vicarious contact affects adolescents’ well-being and substance use. Drawing on data from the Future of Families and Child Wellbeing Study (FFCWS), this study investigates the association between parental incarceration and vicarious police stops, defined as police stops involving parents, siblings, friends, neighbors, or other social ties, and adolescent well-being. Findings indicate that CJS contact is …

Sustaining High-Quality Service-Learning In Research Intensive Universities: A Qualitative Study Of Instructor Perspectives, Marika Koch

Graduate Studies Theses and Dissertations 2026

In a world that often feels disconnected due to our sociopolitical climate, there is a need to create socially aware and civically engaged adults. Service-learning integrated into higher education courses can do that and more. Research indicates that both students and the community benefit significantly when students participate in effective service-learning classes. Students who take service-learning courses in college tend to exhibit higher academic achievement, enhanced social and emotional skills, and greater long-term civic engagement. Effective service-learning courses share three common elements: they foster a strong connection to course objectives, promote reciprocity for all involved, and encourage active student reflection. …

Adapting Dramaturgical Pedagogy Into A Practical Framework For Young Dramaturgs, Kirby Lee

Graduate Studies Theses and Dissertations 2026

Dramaturgy, while more established as practice in professional theatre, remains inconsistently applied and often underutilized in university theatre contexts. Despite its historical significance and continued evolution, some theatre companies and many academic institutions still struggle to clearly define or effectively integrate the dramaturg’s role. This thesis hopes to create a framework for novice dramaturgs by examining the origins and development of dramaturgy, analyzing its shifting functions in contemporary theatre, offering my own dramaturgical experiences through the lens of three quite different plays and finally, establishing basic principles of the discipline. Beyond its historical and professional contexts, this study investigates the …

This study examined how school-level and district-level contextual factors are associated with Algebra 1 achievement in Florida using a multilevel modeling framework. Drawing on statewide publicly available data from the Florida Standards Assessments (FSA), the analysis included schools nested within districts to account for the hierarchical structure of educational data. School-level predictors included absenteeism, economic disadvantage, English language learner status, student mobility, and the proportion of students with disabilities, while district-level variables included poverty and crime rates. Results from the null model indicated that a meaningful proportion of variance in Algebra 1 achievement was attributable to differences among districts, supporting …

Bridging The Gap: How Sociodemographic Factors Shape Adults’ Decisions To Pursue Hearing Aids, Logan Lorié

Graduate Studies Theses and Dissertations 2026

Despite hearing aids becoming more accessible to adults with hearing loss, hearing aid uptake rates remain low, partly due to sociodemographic factors that influence an adults’ decision to pursue amplification. This study systematically reviewed research on how sociodemographic factors – to include age, gender, socioeconomic status, education level, race/ethnicity, and military status – contribute to the decision-making process. This review guided an analysis of these variables using the National Health and Nutrition Examination Survey (NHANES), a large public health database. To ensure enough hearing aid users were included in the analysis, NHANES data were combined across survey cycles from 1999 …

Hunter. Hunted. Human: Warfighters' Emotional Responses To Weapons In Tactical & Strategic Context, Simon Mace

Graduate Studies Theses and Dissertations 2026

Human emotional responses to weapons have long been assumed to be relatively parsimonious, comprised predominately of aggression, anxiety, and fear responses. However, most research on this weapons effect has focused on civilians – who are notably more likely to be targeted by than to employ weapons. So, there is reason to speculate that emotional responses to weapons vary more than previously believed. This is significant for three reasons. First, positive emotional responses generate more desirable combat behaviors, specifically the willingness to engage adversaries. Second, negative emotional responses catalyze an unpredictable range of behaviors, many of which are tactically and operationally …

The Diversity Of Flavivirus Antibody Dependent Enhancement (Ade) Profiles From A Pediatric Cohort In Mexico, Maiesha Samiha Mahmood

Graduate Studies Theses and Dissertations 2026

The Aedes mosquito-borne flaviviruses Zika (ZIKV) and dengue (DENV-1-4) cause an estimated 400 million annual infections globally and pose an increasing threat to public health. Typically, individuals infected with ZIKV or a DENV serotype generate neutralizing serotype-specific antibodies and non-neutralizing, cross-reactive antibodies that bind multiple flaviviruses. Upon secondary heterotypic infection, pre-existing antibodies can either protect or exacerbate disease through antibody dependent enhancement (ADE). ADE occurs when non- or sub-neutralizing concentrations of cross-reactive antibodies facilitate viral uptake into FcγR-bearing myeloid cells, enabling infection of otherwise non-permissive cells and driving severe disease. To date, ADE has not been characterized at a population …

Appraising The Uniform: Stress, Predisposition, And Trust In Police Among Latin American And U.S. Latino Populations, Maren J. Mainx

Graduate Studies Theses and Dissertations 2026

Public trust in police is central to regime legitimacy, yet reforms intended to build trust produce inconsistent results, and communities facing comparable conditions can respond differently to similar policing. This dissertation accounts for that variation by examining how stress shapes citizens’ responses to police visual cues. It proposes a framework in which citizens interpret these cues through their general trust in police—trust that weighs more heavily under stress. This framework is examined through a multi-method design spanning the Americas. Study 1 merges AmericasBarometer data with the Global Police Militarization Dataset across nineteen countries (2010–2023) to examine how stress and national …

Communication College Students And Their Career Readiness: An Evaluation From The Employer's Perspective, Carson Mann

Graduate Studies Theses and Dissertations 2026

Higher education institutions are seen as places that educate students in specific subjects and provide training that leads to either a career or further learning opportunities. Unfortunately, public trust in higher education has plummeted since 2015. The evolution of higher education has been the subject of speculation by various groups, but developing translational skills through effective internships could very well solve the issue at hand. Institutions ought to have data -driven evidence about their disciplines’ effectiveness and their translational ability to the workforce. To understand this, student career readiness must be evaluated. Students' career readiness is a vital measure of …

Development Of The Simultaneous Alcohol And Cannabis Use Expectancy Questionnaire (Sac-Eq), Shane D. Marohnic

Graduate Studies Theses and Dissertations 2026

Background: Simultaneous alcohol and cannabis use (SAC/SAM), defined as using alcohol and cannabis at the same time so that their effects overlap, has been identified as a hazardous form of polysubstance use. Expectancies are a causal mechanism and can be changed with predictable reductions in substance use and associated consequences, yet only one measure has been developed to assess expectancies related to SAC. Due to limitations of the existing measure, this study sought to create a more comprehensive SAC expectancy scale. Method: Three phases of participants (Phase 1, N = 493; Phase 2, n = 4; Phase 3, n …

Comics In The Classroom: Social Science Teachers' Lived Experiences With Comic Art In Instruction, Robert W. Mcintosh

Graduate Studies Theses and Dissertations 2026

This qualitative descriptive phenomenological study explored secondary social science teachers’ lived experiences with comic art in classroom instruction. Existing research suggests that comic art, including comic books and graphic novels, can support student engagement, content understanding, visual literacy, and critical thinking; however, less is known about how teachers experience and make decisions about using comic art in social science education. Framed by Technological Pedagogical Content Knowledge and Social Cognitive Theory, the study treated comic art as a representational instructional technology and examined how teacher confidence and the context of their experience shaped its use. Data were collected through semi-structured interviews …

Show Me The Money: Candidate Attributes, Fundraising, And The Impact On Congressional Representation., Dhanya Nair

Graduate Studies Theses and Dissertations 2026

What explains women’s candidate emergence in congressional primaries? Does candidate education, experience, and background influence how voters donate to male and female candidates? Using an original dataset, I examine the circumstances under which women are more likely to enter a congressional primary.  This thesis accounts for the variation in candidate emergence across Congressional districts related to district partisanship, candidate quality and fundraising capacity.   The theory suggests that the persistent gap in representation is partly due to women self-selecting to run in districts that favor their candidacy.  Strategic entry serves as a buffer against perceived bias in fundraising and electability. Additionally, …

Hidden Gem, Fraught Liability, Or Visible Asset? The Museum Of Contemporary Art Jacksonville, Keidra D. Navaroli

Graduate Studies Theses and Dissertations 2026

This dissertation utilizes a combination of archival research, qualitative interviews, and data-driven analyses to examine how the Museum of Contemporary Art (MOCA) Jacksonville came under the governance of the University of North Florida (UNF). Founded in 1924, MOCA became a cultural institute of UNF in 2009 during the Great Recession. Tracing MOCA’s reinventions and geospatial movements across Jacksonville, this study considers the ideologies that informed the museum’s development, the locations that defined its service to Northeast Florida, and the financial conditions that necessitated its eventual rescue by a public university. The museum’s challenges are reflective of larger tensions in the …
