The Effect Of Extended Reality On The Science Achievement Gap Between Students With And Without Disabilities, Shalece Kohnke

Electronic Theses and Dissertations, 2020-2023

A science achievement gap between students with disabilities (SWD) and students without disabilities continues to persist, impacting academic and occupational outcomes. Traditional science instruction and the abstract nature of science concepts are a barrier to science achievement for students with disabilities. The current research study examined the effect of extended reality (XR; Browser-based 360° virtual reality) on closing the science achievement gap between students with and without disabilities in inclusive biology classrooms using a one group pretest-posttest design. The researcher expands on existing research by utilizing a larger sample size, with free and easily accessible XR technology implemented in 9th …

An Investigation Of Change Mechanisms Using Psychophysiological Data: Child-Centered Play Therapy With Children Exposed To Adverse Childhood Experiences, Caitlin Frawley

Electronic Theses and Dissertations, 2020-2023

Children who endure complex trauma and multiple adverse childhood experiences (ACEs) suffer with various physical, social, and mental health-related consequences, such as increased rates of depression, posttraumatic stress disorder (PTSD), attention deficit/hyperactivity disorder (ADHD), cardiometabolic disorders, substance abuse disorders, ischemic heart disease, and suicidality. Child-Centered Play Therapy (CCPT) is a promising evidence-based child mental health intervention, and researchers have demonstrated the efficacy of CCPT for improving empathy, social competence, behavior problems, and self-regulation among children with multiple ACE exposures. In the current study, the researcher examined the co-regulatory process and relational mechanisms of CCPT with children with histories of complex …

Changes In Preservice Secondary Science Teachers' Views, Beliefs, And Their Nos Teaching During A Science Methods Course Guided By Rfn, Kelsey Beeghly

Electronic Theses and Dissertations, 2020-2023

This multiple-case study investigated the changes in three secondary science preservice teachers' views of the nature of science (NOS), their beliefs about the importance of NOS, as well as how these changes relate to their NOS teaching at the end of a science methods course guided by the reconceptualized family resemblance approach (RFN). RFN is a conceptual framework that visualizes science as a cognitive-epistemic and socioinstitutional system, and its educational applications have recently begun to be explored. Data sources included the pre and post course RFN Questionnaire (Kaya et al., 2019) and individual interviews, as well as each preservice teachers' …

The Effects Of Microgravity On The Development Of Osteoporosis, Jackson Asiatico

Electronic Theses and Dissertations, 2020-2023

Previous research has identified a potential link between microgravity conditions and the onset of osteoporosis, a connection that stems from altered fluidic pathways crucial in nutrient dispersion and cell stimulation. Specifically, the absence of mechanical loading in space environments reduces fluid shear stress, thereby disrupting the normal flow of interstitial fluid in trabecular bone. This disruption greatly impacts the functionality of osteoblasts and osteoclasts, the vital cells responsible for maintaining healthy bones. The focus of this study aims to explore the impact of microgravity on bone loss in astronauts, establishing the connection between the lack of mechanical loading and the …

Late Starts Leading To Native-Like Pronunciation In Second Language Acquisition, Antonio Losavio

Electronic Theses and Dissertations, 2020-2023

This study sought to investigate the self-perceived factors that led adult language learners, who acquired L2 after the critical period, to acquire native like pronunciation in their second language. Given the impact of accent and pronunciation on perceptions of a speaker's status, intelligence and/or competence, there exists a need for thoughtful and comprehensive research into why adult second language learners reach different outcomes in pronunciation attainment. A qualitative phenomenological design was employed to recruit adults who began learning English as an L2 after 12 years old but attained a native-like English accent. Participants recorded vocal samples that were presented with …

Utilization And Costs Of Home Hemodialysis, In-Center Hemodialysis, And Peritoneal Dialysis Among Patients With End-Stage Renal Disease (Esrd) In The United States, Andres Mauricio Garcia Sierra

Electronic Theses and Dissertations, 2020-2023

Chronic kidney disease (CKD) is a condition that requires access to renal replacement therapies (RRTs) to enable patients to live. The use of such therapies has been continuously researched due to the high cost to payers and their patients. This dissertation aimed to analyze the incidence, prevalence, and mortality of renal replacement therapies in patients with end-stage renal disease (ESRD), and document cost trends and analyze possible inequalities in access to these therapies. Based on an integrated health risk management (IHRM) model, this study examined patient characteristics associated with renal replacement therapies in ESRD patients through a pooled cross-sectional study …

Design Of Stormwater Bmps For Surface And Groundwater Protection Based On Site-Scale Soil Properties: Phase I, Kelly Kibler, Lisa Chambers, Melanie Beazley

Florida DOT

Much of Earth’s nutrient cycling takes place in soils. Characteristics of soils control physical, chemical, and biological processes that determine rates of nutrient fluxes, storage, or transformation. As remediation of excess nutrients in stormwater runoff is one function of stormwater Best Management Practices (BMPs), the soil profile constitutes one of the most important factors of BMP design. Variation observed in BMP effectiveness (e.g., why one BMP design works effectively in one place and not another) can often be explained by variations in the soil profile, either through direct means or by a soil’s influence on hydraulics of stormwater flow through …

Who Is (Communicatively More) Responsible Behind The Wheel? Applying The Theory Of Communicative Responsibility To Tam In The Context Of Using Navigation Technology, Sungbin Youk, Hee Sun Park

Human-Machine Communication

By examining how perceived usefulness and ease of use relate to the user’s perception (i.e., communicative responsibility), the communicative behavior of the navigation system (i.e., the landmarks used to give directions), and the context of driving (i.e., familiarity of the driving location), this study applies the theory of communicative responsibility to the technology acceptance model to better understand why users are more likely to adopt certain navigation technologies while driving. We hypothesized that users’ perceived symmetry in communicative responsibility independently and interactively (with communicative behavior of the navigation system and the driving situation) affects perceived ease of use and usefulness …

2021 Oyster Coverage Gis Layer For Mosquito Lagoon, Fl, Linda Walters, Melinda Donnelly, Gabriel Benson, Paul E. Sacks

CEELAB Research Data

Intertidal reefs of Crassostrea virginica (eastern oyster) provide ecologically valuable habitat in estuaries along the Atlantic coast of North America. In Mosquito Lagoon, a shallow-water estuary on the east coast of central Florida, USA, historical aerial imagery was used to document a 24% decline in the live C. virginica reef area between 1943 and 2009. Using 2021 imagery, every living and dead reef in the same region was manually digitized to identify changes during the intervening 12 years. Positive impacts of C. virginica reef restoration that took place between 2007 and 2021 were also digitized to quantify long-term restoration impact. …

Empowering Chinese Students To Regain The “Voice” Via Vygotsky’S Zpd Integrated With The Socratic Seminar, Zhengjie Li Dr.

Journal of English Learner Education

Many Chinese students studying in the United States (U.S.) today report that they do not have a “voice.” They feel marginalized because of a lack of communicative competence in English and their inability to understand Western cultures, especially during their first year in the U.S. (Ching et al.). Some Chinese students are unable to adapt to the academic environment in American high schools, which leads to feelings of exclusion. To smooth this transitional period, this study suggests that the scaffolding (see Bruner, 1978, 1985) from ESL teachers in both verbal and written forms be implemented before students are placed into …

Vertebrate Animal Behaviors And Abundances On Estuarine Shorelines Stabilized With Biodegradable Materials Utilizing Wildlife Cameras, Katherine Guise

The Pegasus Review: UCF Undergraduate Research Journal

Living shoreline stabilization is a restoration technique that utilizes natural materials as breakwaters, plus vegetation landward of the breakwaters, to protect coastlines. This research does not provide information about how new, biodegradable restoration materials affect vertebrates that utilize these shorelines. For this project, I monitored 18 restoration sites along Canaveral National Seashore with wildlife trail cameras: 3 made with cement-infused jute breakwaters, 3 with metal gabion oyster shell breakwaters, and 4 with previously used breakwaters manufactured from plastic mesh oyster shell bags. This project used 4 sites as positive controls (intact vegetation) and 4 as negative controls (highly eroded, no …

Genome-Wide Association Study Of The Maize Crop By The Lasso Regression Analysis, Amir Alipour Yengejeh

Data Science and Data Mining

The accurate estimation of the male flowering period in Maize crops is key for the prediction crop fertility. The recent scientific investigations has shown that the genetic single nucleotic polymorphism (SNP) can contribute in this regard. The genomewide association study (GWAS) is employed to generate these attributes (SNP). But it caused a high-dimensional data in which 4,981 observations with 7,389 SNP attributes. Hence, in this study, we used the penalized regression approach with the least absolute shrinkage and selection operator (Lasso) to reduce the dataset. In this regard, we set the regularization parameter to 0.21. It resulted in a set …

Characterizing Particle Bed Stratigraphy As A Function Of Particle Size In An Airless, Microgravity Environment, Gillian Gomer, Michael Fraser, Anthony Meola, Raquel Guzman

The Pegasus Review: UCF Undergraduate Research Journal

Asteroids and other small planetary bodies are covered in a loose, dynamic layer of multi-sized dusty particles. We are focused on developing methods to further understand this surface regolith behavior to inform future landing missions on these small bodies for resource collection. The Strata-1 experiment was designed to study granular behavior in a passive, microgravity, airless environment. These conditions, simulating that of an asteroid’s surface, were attained by installing Strata-1 aboard the International Space Station for 347 days. In this experiment, we took images of red, green, and blue multi-sized glass shards within a tube to better understand their stratigraphy. …

Paternal Ages And Genetic Diseases And Congenital Anomalies, Neda Hamood

The Pegasus Review: UCF Undergraduate Research Journal

he purpose of this research is to investigate the link between Advanced Paternal Ages (APA) (i.e., APA ≥ 35 years and APA ≥ 50 years) and genetic diseases and congenital anomalies. Currently, the relationship between both APA and genetic diseases and congenital anomalies remains unclear. There is room for improvement, however, to investigate systematically the relationship between specific congenital anomalies in newborns and APA. More recently, the link between APA (as opposed to existing studies analyzing Advanced Maternal Age alone) and genetic diseases has been recognized by researchers, epidemiologists, and various health experts. Thus, this study serves to examine the …

Coping Mechanisms In Graduate School: A Discipline Comparison, Sandra P. Montenegro

The Pegasus Review: UCF Undergraduate Research Journal

The current study aimed to provide an overview of graduate students’ stress and coping mechanisms. Per self-reported questionnaires, participants (N=95) rated their experiences with academic-related stressors, common coping mechanisms, and strain outcomes (somatic symptoms, insomnia, and burnout). This study found that task-related stressors were the most prevalent for graduate schoolwork. More specifically, graduate students in STEM, Arts & Humanities, and Social Sciences rated the amount and difficulty of the tasks (quantitative and qualitative properties of tasks) as the highest stressors in graduate school. The preferred coping strategies across all fields were planning and emotional coping. Additionally, students in STEM reported …

Vulnerability And Resilience In A Tourism Destination, Sergio Alvarez, Alan Fyall

Rosen Research Review

In an industry that is critically vulnerable to hazards, some destinations are hit harder than others by the same or similar events. UCF Rosen College of Hospitality Management researchers, Dr. Sergio Alvarez and Dr. Alan Fyall, have developed a conceptual model that sees the destination's vulnerability as the sum of its physical, social-cultural, economic, ecological/environmental, and institutional vulnerabilities, nestled within its level of exposure to different hazards. Their framework offers to better equip destination management organizations (DMOs) by identifying vulnerabilities and facilitating more effective planning and decision making.

Investigating Plant Physiological Responses To Global Phylogenetic Diversity Of Glomeromycotina, David Z. Mowbray

Honors Undergraduate Theses

Arbuscular mycorrhizal (AM) fungi are ubiquitous symbionts of terrestrial plant species with associations predominantly characterized as mutualistic. In addition to well-documented enhancement of host growth response, more recent analyses have demonstrated the conferral of host benefits under numerous biotic and abiotic stressors. However, much of the established evidence originates from studies involving limited AM fungal diversity. Accordingly, this study sought to evaluate the potential effects of inoculation on plant host physiological traits within a growth chamber environment, investigate potential correlations between host trait responses, & assess the degree of phylogenetic signal observed in trait responses due to the presence of …

Expression Optimization Of The Gst-Gfp Fusion Protein Through The Alteration Of Induction Conditions, Matthew J. Vaccaro

Honors Undergraduate Theses

This research sought to determine which induction condition resulted in the greatest GST-GFP fusion protein expression. It will hopefully serve as a guide for future researchers trying to produce their own recombinant protein containing GST and GFP-tags. The CDNB Enzyme Assay was used to determine the quantity of GST-GFP fusion protein present and tested three variables: IPTG concentration, duration, and temperature of induction. The findings showed that IPTG concentration, temperature, and induction duration all had a significant impact on protein expression. Induction temperatures of 20 °C and 25 °C showed better protein expression at IPTG concentrations of 1.0 mM IPTG …

Analysis Of Lepilemur Edwardsi Seasonal Acoustic Activity, Samantha Henry

Honors Undergraduate Theses

Passive acoustic monitoring (PAM) has historically been used as a noninvasive technique to study biodiversity, activity patterns, distribution, and species dispersal. The use of acoustic data has expanded in ecological research; however, studies focusing on primates are underrepresented, especially for nocturnal species. This study seeks to increase the understanding of acoustic activity in the nocturnal Milne-Edwards' sportive lemur (Lepilemur edwardsi). This species is endangered and endemic to the lowland dry forests in northwest Madagascar. Specifically, this study aims to describe the daily and annual acoustic activity patterns of the L. edwardsi. The PAM survey was conducted using …

Decision-Making And Christianity: Black Queer Women's Mental Health, Deborah Coffy

Honors Undergraduate Theses

This study investigated how Christianity affects Black queer women's decision-making regarding seeking mental health services. Those who felt they met the inclusion criteria completed a Basic Demographic Survey. After vetting these individuals, eleven female participants—who are both Black and queer—were asked to participate in an individual semi-structured qualitative interview. The interview focused on one's journey with mental health, societal and relationship influences, Black and LGBTQ+ identity, influences from conservative, traditional, or mainstream Christianity, and sense of self. Although Christianity may not have directly impacted most of the women in this study to seek mental health services, Christianity did have an …

Evaluating Digital Cognitive Biomarkers As A Noninvasive Diagnostic Tool For Alzheimer's Disease: Correlations With Classic Csf Biomarkers, Kasey Corripio

Honors Undergraduate Theses

Alzheimer's Disease (AD) is a neurodegenerative disorder affecting over 35 million people. Early diagnosis and intervention are crucial for improving outcomes. Digital Cognitive Biomarkers (DCBs) offer a promising approach for early detection and disease management, quantifying cognitive processes of encoding and retrieval through a hierarchical Bayesian cognitive processing model using wordlist memory tests. We hypothesize that DCBs will correlate with classic AD cerebrospinal fluid (CSF) biomarkers (Aβ42, T-tau, p-tau) in patients with varying cognitive decline levels compared to healthy elderly controls. Using Alzheimer's Disease Neuroimaging Initiative (ADNI) data and paired Pearson correlation coefficient analysis, our results support the hypothesis, indicating …
