Machine Learning Applications In Advanced Additive Manufacturing: Process Modeling, Microstructure Analysis, And Defect Detection, Peter Warren

Electronic Theses and Dissertations, 2020-2023

Non-destructive evaluation (NDE) techniques are critical for assessing the integrity, health, and mechanical properties of materials manufactured from various methods. High fidelity NDE techniques are essential for quality control but often lead to massive data generation. Such a vast data load cannot be manually processed, this leads to a severe bottleneck for process engineers. Machine learning (ML) offers a solution to this problem by providing powerful and adaptable algorithms capable of learning patterns, identifying features, and finding hidden relationships in large sets of data. Various ML models are used in this work to improve predictions, improve measurements, detect anomalies, classify …

A Linear Regression Model To Predict The Critical Temperature Of A Superconductor, Amir Alipour Yengejeh

Data Science and Data Mining

Since the superconductivity has been introduced, almost all studies in this area have been striving to predict the critical temperature ($T_{c}$) through the features extracted from the superconductor's chemical formula. In this study, thus, we are interested in exploring the linear association between $T_{c}$ and the related features.

Avicenna's Doctrine Of Emanation And The Sphere Of The Heavens, Brian C. Manere

Honors Undergraduate Theses

Avicenna argues that the celestial spheres each have a soul, termed the motive soul, which is emanated by the first celestial intellect––a body of knowledge which knows itself. Despite outlining the powers of the motive soul, Avicenna does not formally investigate the psychology of the spheres nor their volition. Rather, he presents their volition as a mystery and leaves it to posterity to solve. In an attempt to resolve this mystery, I will argue that it is a direct result of Avicenna having purposefully written a repeated gap into his account of emanation such that there is no clear account …

Treatment Of The Differently Abled: Representations Of Disability From Victorian Periodicals To Contemporary Graphic Narratives, Rachelle Echevarria

Honors Undergraduate Theses

In recent years, a number of efforts have been made to promote diversity, equity, and inclusion in academic institutions, the workplace, and to examine and analyze representations of marginalized populations in a variety of literary and cultural contexts. These efforts usually acknowledge past mistakes, emphasizing the idea that history shall not and should not repeat itself. While analyzing the representations of disability is important in its own right, it's also important to understand why these perceptions exist. This thesis suggests that when the representations of disabilities from different mediums and from different time periods are examined in relationship, readers may …

Spilling The Tea: A Comparative Analysis Of Development In Ex-British Colonies, Niamh L. Harrop

Honors Undergraduate Theses

The British Empire was the largest empire the world has ever seen, and as such, has significantly impacted many of the countries it formerly held as colonies. Imposing a Western style of governance would change the political operations of a nation and would fundamentally shift power dynamics within the country. Through a review of the existing literature on the subject, this thesis examines the effects that British imperial rule had on four different countries in both their social and economic development in the post-colonial era. Overall, the results indicate that Britain failed to set their colonies up for long-term development …

Before They Could Be Saved: Aids Voices Before Protease Inhibitors, Julian J. Willis

Honors Undergraduate Theses

The intent of this thesis is to explore writing during the start of the AIDS epidemic in the U.S. States. This time period encompasses the early 1980s to mid-1990s before Protease Inhibitors were FDA approved which was the medical breakthrough drug that helped turn an HIV diagnosis from a death sentence to a chronic condition. This thesis will be an examination of three themes: “Gay White Cis Male Experience of HIV/AIDS”,” Marginalized Identity Experience of HIV/AIDS” and an exploration of two plays written during the height of the AIDS epidemic that were later turned into HBO productions: The Normal Heart …

"Auto"-Exploitation: A Marxist Examination Of Self-Driving Cars, Parker Duvall

Honors Undergraduate Theses

In this thesis, I argue that a neo-Marxist critical theory perspective on self-driving cars shifts critical conversations from risks and benefits to concerns about the commodification of free time necessary for our human experience of autonomy. First, I outline that neo-Marxist perspective by charting the different types of power exercised by a capitalist in order to increase their surplus. I then analyze Karl Marx's conception of time in economic exchange to show that, under capitalism, power is exercised over labor through the commodification of workers' free time. I then introduced Michel Foucault's concept of biopower to transition to the commodification …

Professional Perception Of Gaps In Adhd Diagnosis And Treatment In Young Girls, Claudia Caputo

Honors Undergraduate Theses

ADHD has become a common place subject in both the scientific community and the common public. ADHD is talked about in the media, schools, and is a common conversation amongst parents. Attention Deficit Hyperactivity Disorder has become prominent due to increased research but also due to increased accessibility of this research for the public. Contributing to this trend, there is an increase in open conversations about mental health awareness on social media. This phenomenon of people openly speaking about ADHD has led to more teens and young adults seeking diagnostic assessments and treatments for their symptoms. (Coppersmith et al., 2015) …

Changing Public Opinion On Socialism, Claudette A. Medina

Honors Undergraduate Theses

This introduction leads to the literature review, beginning with an explanation and description of socialism and political ideologies. I also touch upon historical events that shaped the perspectives of the respective generations, such as the Civil Rights movement and 9/11. After the literature review is a theory section emphasizing the life-cycle effect and period effects relevant to the research conducted later. Then comes the hypothesis and methodology section. My research hypothesis is that period effects will make Gen Z more receptive to Socialism than the Baby Boomer/Traditionalist Generation. This is soon proven correct with supporting data from opinion surveys about …

Impact Of Childhood Adversity On Executive Functioning And The Relationship Between Hypervigilance And Heuristics Among College Students, Tamara S. Van Newhouse

Honors Undergraduate Theses

The topic of exposure to childhood adversity has comprehensively been explored, and the effects of childhood trauma can undoubtedly impact a person on a lifelong continuum, still, investigation is unceasingly conducted. Much research has yet to be done when considering early adversity's outcomes on various stages throughout life and just how reoccurring consequences from early trauma may impair regulatory abilities and executive functioning beyond childhood. Research objective is to discover how early adversity influences later executive functions in conjunction to heuristics and the effects of hypervigilance in a college student populace. This study aims to examine the several variable differences …

Speech-Language Pathologists' And Speech-Language Therapists' Role Working With Youth In The Juvenile Justice System, Maria Cuza

Faculty Scholarship and Creative Works

Purpose: This paper aims to explore the relationships among local food consumption experience, cultural competence, eudaimonia, and behavioral intention. Building upon acculturation theory, need hierarchy theory and self-determination theory, the current study develops a conceptual model of local food consumption as international tourists' acculturation process.

Design/methodology/approach: This study collects data from 305 Chinese outbound tourists and uses partial least squares-structural equation modeling to examine the developed model.

Findings: The findings reveal a significant effect of the local food consumption experience, consisting of novel, authentic, sensory and social dimensions, on cultural competence, which subsequently evokes eudaimonia and behavioral response toward local …

Implications Of An Exogenous Shock (Covid-19) On Wine Tourism Business: A Portuguese Winery Perspective, Alexandre Guedes, Britta Niklas, Robin M. Back, Joao Rebelo

Faculty Scholarship and Creative Works

This study investigates the impact of an exogenous and unexpected shock (COVID-19) on the wine tourism business from the winery's perspective. A sample of 146 Portuguese wineries was surveyed. The econometric results show that the share of wine tourism sales, the amount of dependence on exports and the assertiveness of brand recognition have a structural effect on direct-to-consumer tasting room wine sales, even when the winery's business is disrupted by a shock that degrades the dynamics and flows of international trade. The research establishes a starting point that allows to understand the implications of an exogenous shock on the structure …

Attention Deficit Hyperactivity Disorder, Self-Esteem, And Identity Among College Students, Julie Hall

Honors Undergraduate Theses

The purpose of this study was to explore if Attention Deficit Hyperactive Disorder (ADHD) is related to identity in undergraduate adults, as well as their self-esteem. Also investigated was whether prior diagnosis (including early detection versus later-in-life detection) would be related to higher self-esteem and healthier identity formation. College students in large metropolitan southeastern universities enrolled in psychology classes (N = 368) took an anonymous online self-report survey battery in exchange for course credit. The screening tool for ADHD identified close to 50% of the sample as possibly having ADHD, which is much higher than any previous study has …

Benefits Of A Family-Based Judo Program For Parents Of Children With Autism Spectrum Disorder, Jeslin George

Honors Undergraduate Theses

A diagnosis of Autism Spectrum Disorder (ASD) can impact the entire family. Parents of children with ASD reportedly have greater stress levels, family conflict, financial concerns, and poor health habits than parents of neurotypical (NT) children. While many parent-focused interventions have been developed, these interventions focus on parent training and child behavior outcomes rather than the health and well-being of the parents. Therefore, this study aimed to examine the effects of a 15-week family judo program on physical and psychosocial health in parents of children with ASD. A total of 18 parents of children with ASD participated in a weekly …

Exploring The Impact Of Cultural Background Among Asian And Non-Hispanic White Populations On Organ Donation, Doyoung Ahn

Honors Undergraduate Theses

Background: The demand for organ donation is increasing but there is always a lack of organ donor supply. To receive an organ donation, specific criteria must be met. Matching criteria between the donor and the recipient is critically important. The likelihood of having a capable organ increases when the donors and recipients have the same ethnicity. However, the number of organ donors differ significantly based on ethnicity.

Purpose: The purpose of this literature review was to explore the impact of cultural background and education among the Asian and non-Hispanic White population on organ donation and how it impacts individuals' decisions …

Advocacy With Context: The Role Of Pediatricians In Breastfeeding Success, Sanya Bansal

Honors Undergraduate Theses

Although the importance of breastfeeding is almost universally accepted, the rates of breastfeeding are improving very slowly. The current literature provides much insight as to how medical professionals such as obstetricians and lactation specialists could improve the rates of breastfeeding. The pediatrician could encourage breastfeeding at a prime opportunity: during post-natal visits. Unfortunately, there is limited research on what role the pediatrician plays in breastfeeding success. This study used in-depth, qualitative interviews from four pediatricians to gather data on the true role of the pediatrician in breastfeeding. These pediatricians were selected based on the diverse patient population they serve, considering …

Examining The Association Between Covid-19 And Anxiety In College Students With Varying Personality Traits, Ridha Anjum

Honors Undergraduate Theses

The goal of this thesis was to examine the relationship between personality types (i.e., extraversion and neuroticism) and anxiety levels among college students during the height of the pandemic. Specifically, this study examined whether factors contributed to anxiety and whether differences in anxiety scores differed by personality trait. It was hypothesized that individuals who scored high in both extraversion and neuroticism would report an increase in anxiety during the height of COVID-19 pandemic. Neuroticism is linked to emotional responses to a negative event (e.g., such as COVID), which may play a role on anxiety levels. The level of extraversion that …

The Effect Of E-Cigarette Vape On Oral Cell Proliferation Using 3d Spheroids As A Preclinical Model, Vikram Chinnaiyan

Honors Undergraduate Theses

E-cigarettes have recently become increasingly popular, especially amongst middle and high school students. Although they are marketed as safer alternatives to tobacco cigarettes, they produce toxic metals and carcinogenic nitrosamines. This thesis studies the effects of e-cigarette aerosol on the growth and proliferation of oral epithelial cells because the consequences of vaping, including a potential risk for aberrant growth leading to cancer, are not well understood. Cells were grown in matrigel, causing the formation of three-dimensional spheroids modeling the physiological architecture of the oral epithelium. Those spheroids were chronically exposed to vape with different treatment conditions to study the functional …

Split Catalytic Probes For The Detection Of Monkeypox Virus, Jaehyun Ahn

Honors Undergraduate Theses

The COVID-19 outbreak highlighted the important role that diagnostic tests play in the healthcare system. To reduce the impact of infectious disease outbreaks, the development of rapid and cost-effective point-of-care-tests (POCTs) is crucial. With the dissemination of the Monkeypox (Mpox) virus, it became a necessity to produce POCTS that are inexpensive and easy to use. This work explored the construction of two colorimetric assays that aim to detect Mpox genetic signatures. One is based on the split-peroxidase-like deoxyribozyme probes (sPDz), while the other utilizes a cascade system of split RNA-cleaving deoxyribozyme (sDz) and peroxidase-like deoxyribozyme (PDz). Both rely on catalytic …

The Effect Of Educational Versus Recreational Screen Time On Depression Levels Among University Students, Gage Guettler

Honors Undergraduate Theses

Despite the amount of people currently using technology and the overwhelming amount of data already presented on the topic of how technology affects a person's mental health, there seems to be little information on how the different types of activities on the different types of screens affect university student's mental states. This research study examined the amount of time that a University of Central Florida (UCF) student spends on what was defined as educational activities in front of screens and what was defined as recreational. The definitions of what is educational and what is recreational screen time came from a …

Psychology Of Platonic Relationships, Amber V. Heinig

Honors Undergraduate Theses

Romantic relationships (RR) regarding attachment styles and theory have been widely studied, whereas platonic relationships (PR) have received comparatively less attention in research. This study aims to explore two hypotheses: (1) individuals exhibit more avoidant behavior in platonic relationships rather than anxious behavior, and more anxious behavior in romantic relationships than in platonic ones; (2) attachment styles in platonic relationships manifest uniquely and can exist independently of romantic attachment. This research aims to better understand the way that attachment differs between both relationship types. Through a quantitative study involving a survey with a 5-point Likert scale measuring attachment, administered to …

Long Term Effects Analysis Of Children Exposed To Postpartum Depression, Asheria Foster

Honors Undergraduate Theses

The purpose of this study is to explore and understand any correlation between a mother having postpartum depression and her now college-level child having a mental illness. The research question posed for this study was: Is there a correlation between maternal postpartum depression and the development of mental illnesses in college students? Studies have shown that there is a correlation in early childhood development, but there are deficits when it comes to long-term follow-up. Data for this study was collected via online surveys on SONA UCF. The results from the Chi-square test imply a strong association (p = .007) at …

Narrating The Fragmenting Brain: Alzheimer's Disease Neuronarratives, Bonnie Cross

Electronic Theses and Dissertations, 2020-2023

This dissertation examines the representation of Alzheimer's Disease (AD) neuronarratives (NN), works that centralize the brain or consciousness in the plot, in multiple modalities to support that argument that neuronarratives should be expanded into a transmedia genre. These modalities include neurogames, neurocomics, and neuromemoirs. These three modalities were analyzed to determine how selfhood and social networks are represented by characters or authors with Alzheimer's Disease. As AD is often viewed as the loss of selfhood and is associated with isolation, these works combat these stigmas and complicate representations of the disease. The use of images was also examined in neurogames …

Developing Cost-Effective Specialty Adsorbents To Meet The Emerging Challenges Of Pollutant Removal In Surface Water Systems, Diana Ordonez

Electronic Theses and Dissertations, 2020-2023

The production of clean water is emphasized under the United Nations goals for sustainable development (SDGs), enlightening the acute need of developing new sustainable technologies in all disciplines. SDGs have urged all engineers in the 21st century to mitigate pollution of drinking water sources and prevent all receiving waterbodies from the impact of agriculture discharge, wastewater effluent, and stormwater runoff. Current water matrix constituents of concern include traditional pollutants (i.e., total nitrogen and total phosphate), natural organic matters (i.e., total organic carbon (TOC), tannic acid), heavy metals (i.e., copper, calcium), and harmful algae toxins (i.e., microcystin), as well as contaminants …

Holding An Empathic Lantern To Help Depressed Friends Find Their Way Out Of The Darkness: An Examination Of Intention To Offer Social Support Guided By The Reasoned Action Approach, Laura Boutemen

Graduate Thesis and Dissertation 2023-2024

Guided by the reasoned action approach, this two-fold research first used an online open-ended elicitation survey to identify beliefs held by undergraduate students (N = 397) pertaining to offering social support to depressed friends or peers. Then, these findings were included in a closed-ended survey study to assess the influence of intention on the social support behavior among students (N = 509). Additionally, the influence of the antecedents of intention (i.e., attitude, perceived norms, perceived behavioral control) on behavioral intention was explored. Next, the study examined whether beliefs predicted the antecedents of intention. Last, the influence of background …

Impact On Infinite Asteroids: Analysis Of Ejecta Outcomes In Small Body Binary Systems, Jennifer Larson

Electronic Theses and Dissertations, 2020-2023

Binary asteroid systems make up roughly 15% of objects occupying near-Earth space, the Main Belt, and trans-Neptunian space. The impact history of asteroids in binary systems represents an interesting aspect of the general problem pertaining to the nature and evolution of surfaces for such objects. Specifically, the post-impact dynamics of ejecta and its relation to surface modification is a challenging question owing, in part, to the unusual gravitational field in a binary system and the subsequent capture and emplacement of debris on either binary component. Observable differences or similarities between the two bodies in the color, reflectance, thermal properties, and …
