Dormant Propagules In Demographic Studies: A Recurrent Bias And Potential Solutions, Federico Borghesi

Graduate Thesis and Dissertation 2023-2024

In the face of unprecedented anthropogenic change, we increasingly turn to emergent technologies and extensive data sets for solutions that complement much needed systemic changes in our societies. These technological solutions, however, must be approached with care. We must recognize and address biases in the way data has been accumulated. In demographic studies, dormant life stages, such as seed banks, and other cryptic factors have often been neglected. The potential consequences of these omissions have been extensively described in the literature. In the first chapter, I analyze patterns of seed bank omissions in demographic models, finding unjustified omissions are widespread …

The Dynamical Measurement And Modeling Of Metacognition And Engagement Using Self-Report And Multimodal Data With Advanced Learning Technologies, Megan Wiedbusch

Electronic Theses and Dissertations, 2020-2023

Interdisciplinary research has demonstrated that learning and problem solving with advanced learning technologies (ALTs) such as intelligent tutoring systems, simulations, hypermedia, serious games, and virtual reality can promote and foster the development of 21st century skills (e.g., collaboration, problem solving, self-regulated learning) by measuring and using the interactions between cognitive, affective, metacognitive, motivational, and social (CAMMS) processes. Interdisciplinary researchers focused on self-regulated learning (SRL) have developed several theoretical models which model students' CAMMS processes and their learning behaviors. However, when empirically testing these models, researchers face complicated methodological decisions around modeling, measuring, processing, and analyzing student data. Many of these …

Algorithms And Variations On The Positional Burrows-Wheeler Transform And Their Applications, Ahsan Sanaullah

Electronic Theses and Dissertations, 2020-2023

In this dissertation, we develop algorithms and variations on the Positional Burrows-Wheeler Transform (PBWT). The PBWT is a data structure that stores M binary strings of length N while allowing efficient search. We develop the dynamic-PBWT (d-PBWT). The d-PBWT is a variation of the PBWT that allows its relevant algorithms to run with unchanged time complexity, but also allows efficient insertion and deletion of haplotypes. We provide insertion and deletion algorithms on the PBWT with average case O(N) time complexity. We also improve upon the query algorithms for the PBWT. Durbin described a set maximal match query algorithm on the …

The Service-Learning Marine Conservation and Restoration class organized and planned an International Coastal Cleanup that was held at Canaveral National Seashore on September 23, 2023. We operated educational tables that allowed for community engagement and provided an understanding of the presence of microplastics in the ecosystem. The team created promotional posters to inform the public about the event and what would be taking place throughout the day. We shared these posters in our spheres and garnered interest from those in the UCF community and abroad. We had the opportunity to remove harmful debris throughout many crucial habitats of the Canaveral …

Transforming Costuming Design: Costuming For The Actor's Comfort, Lisa Evenson

Electronic Theses and Dissertations, 2020-2023

This thesis explores ways to transform costuming concepts for theatre productions that provide a more inclusive and comfortable environment for actors while still maintaining the essence of the characters they are portraying. This thesis examines theatrical bodies of work as case studies to illustrate options for incorporating costume designs that take into consideration the emotional and physical welfare of the actors. The purpose of this study is to inform theatre teachers how to create costumes that aid in psychological comfort of students regarding gender identity and age, as well as for flexibility in casting due to disproportionate gender ratios that …

Keeping The Ball Alive: The Marriage Between Sports And Acting, Giuseppe Pipicella

Electronic Theses and Dissertations, 2020-2023

This thesis examines the link between sports and theatre from the actor's perspective and concludes that these two practices should be used together to achieve optimal performance. Using context provided by great physical theatre practitioners such as Jacques LeCoq, Vsevolod Meyerhold, and Rudolf Von Laban, the candidate used his past experience as a gymnast and a soccer player, and the teachings of Timothy Gallwey's The Inner Game of Tennis, to craft a rehearsal and performance regimen for Theatre UCF's production of Paula Vogel's Indecent. This regimen included an experiment where he alternated days in which he swam to days in …

The Process Is A Journey, Victoria Micaletti

Electronic Theses and Dissertations, 2020-2023

Actors are tasked with the opportunity to perform roles from multiple assorted styles of theatre performance throughout their career. How can performers best create an effective acting process that allows them to develop a pathway that is unique and dynamic across all styles to best embody the characters that they are cast as? I am seeking to refine and develop an approach that will be comprised of a series of steps which include exercises from the acting techniques of Jerzy Grotowski, Michael Chekhov, and Konstantin Stanislavski to create a character that is unique and dynamic. Through the investigation of the …

Body-Image Distress In Breast Cancer Survivors And Their Evaluation Of Medical Tattooing Following Surgery, Miranda Proctor

Graduate Thesis and Dissertation 2023-2024

A review of the literature reveals a high incidence of body-image distress among breast cancer survivors who have undergone surgery, which is a natural response to the significant changes in their appearance. Reconstructive surgery, utilizing implants or flaps, may be employed to restore breast size and shape. Medical tattooing can simulate the nipple-areola complex and decorative appliques can conceal scars and skin color variations. Both reconstructive surgery and medical tattoos are associated with patient-reported satisfaction, yet further research is necessary to understand their combined impact on body-image distress. To investigate this, a survey was distributed among national breast cancer support …

Time Of Day Effects On Maximal Effort Strength/Power And Fatigability Assessments, Justine Renziehausen

Electronic Theses and Dissertations, 2020-2023

The circadian rhythm is a 24-hour cycle present within most biological systems that is controlled by the suprachiasmatic nucleus (SCN) of the hypothalamus. The SCN is responsible for synchronizing the peripheral "clocks" present in other tissues so that all rhythms, such as heart rate, body temperature, and hormone secretion, are functioning together. As most systems experience a circadian rhythm, physical performance likely does as well. Previous studies have investigated time of day effects on maximal strength, power, and endurance performance, however, factors (e.g., sex, chronotype, age, etc.) have not clearly been distinguished. Additionally, body temperature has been suggested to be …

The Perfect Storm: Motherhood, Intimate Partner Violence, And Covid-19, Kelly Blauschild

Electronic Theses and Dissertations, 2020-2023

Intimate partner violence (IPV) is an insidious societal problem with potentially lethal ramifications. At the onset of the COVID-19 pandemic, widespread conditions and virus risk mitigation procedures like social distancing and stay-at-home orders exacerbated factors that contribute to IPV such as poverty and substance use. Though anyone can experience IPV, mothers carried unparalleled burdens in the early weeks of the COVID-19 pandemic such as increasing childcare responsibilities, growing financial difficulties, and worsening mental health, and many of these factors have been linked to experiencing IPV. The growing body of literature indicates a rise in IPV during COVID-19, but little has …

Reflections On White-Passing Black Identity, Edi Mucka

Electronic Theses and Dissertations, 2020-2023

Now, there are more options than ever for racial identity. Identities such as Black, White, Native, Asian, and Latino have put into contention how past racial boundaries and definitions interact with newer racial color lines. Racial passing is one concept that captures both older and newer forms of identity maintenance. Racial passing refers to when a person classified as a member of a racial group is accepted or perceived as a member of another. In this thesis, I review the literature on racial passing to understand its history and theoretical explanations. Based on the review, I examine a convenience sample …

Becoming Racially Aware: A Social Process Of (Re)Constructing An Alternative White Identity, Ashley Sobke

Electronic Theses and Dissertations, 2020-2023

Structural and systemic mechanisms reinforce institutionalized racism, whiteness, and white supremacy in the United States. These mechanisms prove adaptable and resilient, shifting and changing to continuously restructure and reinforce the material reality that people experience within a racialized social order. White people's incomprehension of complicity in racism and privilege, along with color-blind ideologies, perpetuate racialized disparities resulting from this social order and render white superiority as "normal" and "universal." This underlies an often internalized sense of normative, white American identity interconnected with racism and white supremacy. In a society where many white Americans remain sheltered from and/or resistant to acknowledging …

Ivf So White, So Medical: Digital Normativity And Algorithm Bias In Infertility On Instagram, Caitlyn M. Jarvis, Margaret M. Quinlan

Human-Machine Communication

Increasingly, women experiencing infertility are turning online to social media platforms, like Instagram, to engage with a support network and foster empathy. However, Instagram is also noted for its augmentation of White, cis, and heteronormative femininity through a process of silencing and minoritizing alternative, non-White voices. Through an inductive analysis of the most frequently used infertility hashtags, we collected and analyzed 252 Instagram posts to investigate how these algorithmic practices may socially construct the idealized IVF experience through communicating normative expectations. We identify predominant patterns of use that reinforce stratification within infertility treatments as primarily accessible to White women and …

Designing A Loving Robot: A Social Construction Analysis Of A Sex Robot Creator’S Vision, Annette Masterson

Human-Machine Communication

In 2018, one of the world’s first sex robots was released by CEO Matt McMullen and his company, RealDoll. With artificial intelligence capabilities, the Harmony model is meant to support and converse with users. Using a social construction of technology theory lens, this study develops the theory’s fourth level of analysis, emphasizing mass media’s construction abilities. A critical discourse analysis of 38 publicity interviews found a tendency to emphasize the companionship of sex robots while envisioning a future where integration is normalized, and a sentient robot is possible. As the creator, McMullen’s vision could determine the future of robotic design, …

The Evolution Of Gendered Software: Products, Scientific Reasoning, Criticism, And Tools, Victoria A. E. Kratel

Human-Machine Communication

Over the past 7 decades, gendered software has become globally established. In this theoretical distribution, I outline the evolution of gendered software. The journey of gendered software started with the raw idea fueled by Alan Turing’s imitation game in the 1950s. And only shortly thereafter, in the 1960s and 1970s, the first gendered software products like Joseph Weizenbaum’s ELIZA were developed. Thus, academia took its time to not only explore technological aspects, but to further investigate the matter of gender in the 1990s CASA-paradigm (Nass et al., 1994) and Media Equation (Reeves & Nass, 1996). As these theories reasoned the …

Gender Ambiguity In Voice-Based Assistants: Gender Perception And Influences Of Context, Sandra Mooshammer, Katrin Etzrodt

Human-Machine Communication

Recently emerging synthetic acoustically gender-ambiguous voices could contribute to dissolving the still prevailing genderism. Yet, are we indeed perceiving these voices as “unassignable”? Or are we trying to assimilate them into existing genders? To investigate the perceived ambiguity, we conducted an explorative 3 (male, female, ambiguous voice) × 3 (male, female, ambiguous topic) experiment. We found that, although participants perceived the gender-ambiguous voice as ambiguous, they used a profoundly wide range of the scale, indicating tendencies toward a gender. We uncovered a mild dissolve of gender roles. Neither the listener’s gender nor the personal gender stereotypes impacted the perception. However, …

Gender And Human-Machine Communication: Where Are We?, Leopoldina Fortunati, Autumn P. Edwards

Human-Machine Communication

In this introduction to the fifth volume of the journal Human-Machine Communication, we present and discuss the five articles focusing on gender and human-machine communication. In this essay, we will analyze the theme of gender, including how this notion has historically and politically been set up, and for what reasons. We will start by considering gender in in-person communication, then we will progress to consider what happens to gender when it is mediated by the most important ICTs that preceded HMC: the telephone, mobile phone, and computer-mediated communication (CMC). We outline the historical framework necessary to analyze the last section …

The Y-Chromosome's Role In Sexually Dimorphic Evolution And Mother's Curse Compensation, Tobias Nielsen

Electronic Theses and Dissertations, 2020-2023

The Y-chromosome and mitochondria (containing mtDNA) appear entirely dissimilar, the former being a sex chromosome found in the nucleus and the latter an organelle with thousands of copies in the cytoplasm. However, both experience uniparental inheritance, with Y-chromosomes being patrilineal and mitochondria matrilineal. This leads to various other similarities including haploidy, high mutation rates, and limited or lack of genetic recombination. Moreover, the low number of protein-coding genes contained on both led to the belief that neither contributes significantly to the adaptive evolution of complex traits. However, recent studies show the Y-chromosome and mitochondria both influence roughly 10% of male …

Ceria Defect Engineering Using Thin-Films/Ald And Biological Applications, Udit Kumar

Electronic Theses and Dissertations, 2020-2023

Ceria nanostructures have been utilized for various engineering applications due to their unique defect structure, enabling them to have regenerative redox properties. The ability to shuttle between Ce3+ and Ce4+ oxidation states extends to unique properties. Defect level in ceria is usually expressed in the Ce3+/Ce4+ ratio. It can be achieved by varying the size(0 to 3D), morphologies, dopants, hetero-nanostructures, and external stimuli. However, it is still a challenge to have precise control over defect structures in the ceria lattice. The current study aims to explore the thin film deposition techniques for cerium oxide using ALD (Atomic layer deposition) and …

Extracellular Vesicle-Associated Biomolecules As Potential Biomarkers For Alzheimer's Disease Diagnosis, Lina Bedoya Martinez

Electronic Theses and Dissertations, 2020-2023

Alzheimer's disease (AD) involves progressive neurodegeneration leading to the loss of normal neuronal function. Extracellular accumulation of amyloid-beta (Aß), through the abnormal cleavage of the amyloid precursor protein (APP) by ß- and γ-secretases, is one of the hallmarks of AD. Current research focuses on finding potential candidates for biomarkers and techniques with improved sensitivity for early disease detection. Extracellular vesicles (EVs) found in body fluids are a source of biomarkers for AD diagnosis. EVs transport pathologically significant biomolecules, like nucleic acids and proteins, across the blood-brain barrier, mediating local and distant cell-to-cell communication. Therefore, this study evaluated EV-associated DNA and …

Gene-Poor Y-Chromosomes Substantially Impact Male Trait Heritabilities And May Help Shape Sexually Dimorphic Evolution, Ken Fedorka

Research Data and Datasets

How natural selection facilitates sexually dimorphic evolution despite a shared genome is unclear. The patrilineal inheritance of Y-chromosomes makes them an appealing solution. However, they have largely been dismissed due to their gene-poor, heterochromatic nature and because the additive genetic variation necessary for adaptive evolution is theoretically difficult to maintain. Further, previous empirical work has revealed only Y-linked sign epistatic variance segregating within populations, which can often impede adaptive evolution. To assess the evolutionary impact of Y-linked variation, we established replicate populations in Drosophila simulans containing multiple Y-chromosomes (YN populations) or a single Y-chromosome variant (Y1 populations) drawn from a …

Figuring Embedded Librarianship: An Analysis Of The Embedded Journalist Metaphor In The Professional Discourse, Rachel L. Edford

Faculty Scholarship and Creative Works

In the wake of the COVID pandemic, many academic libraries sought virtual instruction options, like the embedded librarian model, bringing renewed interest to the topic. Debates defining embedded librarianship are plentiful and varied, but a review of the professional literature reveals a commonly used metaphor comparing embedded librarians to embedded journalists. This paper analyses the prevalence of that metaphor in the professional discourse through the lens of cognitive metaphor theory (CMT) to reveal the semantic and pragmatic implications of its use. CMT highlights the power of figurative language to reflect and define professional identities. The metaphor’s militaristic rhetoric counters negative …

The Epistemology Of Complexity And "Doing" Interdisciplinarity, Sharon Woodill

Interface: The C3 Lab Knowledge Commons

Complexity is now well established as the driver of interdisciplinarity, but what this means for how knowledge is ‘done’ within Interdisciplinary Studies has not been well developed. This paper examines the theory of complexity and unpacks its epistemological implications for doing interdisciplinary work. The epistemology of complexity demands a cognitive toolkit that includes such things as open-mindedness, tolerance of uncertainty and ambiguity, and intellectual courage. This paper draws out these connections and suggests implications for curriculum development in Interdisciplinary Studies.

Microplastics: Water And Oyster Data For The Indian River Lagoon, Linda Walters, Casey Craig

CEELAB Research Data

Microplastic (MP) abundances in surface waters and tissues of the oyster Crassostrea virginica were examined for one year in the Indian River Lagoon (IRL), a 251-km long estuary on the east coast of central FL, USA to better understand spatial and temporal variability. A total of 3755 MP were found in 44% of lagoon-wide water samples. Mean density (± CI) was 1.47 ± 0.09 MP/L. Central IRL sites had the lowest MP abundance, while the south had the most, likely associated with proximity to urbanization, inlets (MP sinks) and tributaries (MP sources). More MP were found in water …
