A Teleosemantic Theory Of The Deep-Unconscious: A Response To John R. Searle's Account Of The Unconscious, Kelly Adkins
A Teleosemantic Theory Of The Deep-Unconscious: A Response To John R. Searle's Account Of The Unconscious, Kelly Adkins
Electronic Theses and Dissertations
In mind, John R. Searle dismisses the deep-unconscious on the grounds that it neither satisfies the connection principle nor does it exhibit intentionality. I argue against Searle's account of the unconscious. My initial reason for rejecting Searle's account is that he sacrifices the theoretical virof explanatory power for the sake of ontological simplicity. The reason the unconscious mind gained theoretical sustenance in the first place was to understand and explain various aspects of human behavior that consciousness cannot account for, so any good theory of the unconscious ought to fill this explanatory gap. By oversimplifying the unconscious, Searle's account cannot …

A Complex Calculus: How Message Format And Processing Route Coordinate To Influence Hpv Vaccination Message Persuasiveness Among Young Adults, Laura Boutemen
Electronic Theses and Dissertations
Human papillomavirus (HPV) infection may lead to cancer and genital warts yet can be prevented by a safe and effective vaccine recommended for individuals up to 26 years old. HPV vaccination rates remain low among college aged adults that represent a catch-up population still eligible to receive the HPV vaccine. This present study is a theory-based investigation employing the Heuristic Systematic Model to explore the effect of message format and processing route on attitude and behavioral intention in the context of HPV vaccination. Undergraduate students aged 17-26 years old (N = 261) from various majors (e.g., STEM, social sciences, humanities) …
Mechanism Design Of A Compact 4-Dof Robotic Needle Guide For Mri-Guided Prostate Intervention, Shihao Zhang
Mechanism Design Of A Compact 4-Dof Robotic Needle Guide For Mri-Guided Prostate Intervention, Shihao Zhang
Electronic Theses and Dissertations
In the past several MRI compatible robotic needle guide devices for targeted prostate biopsy have been developed. The large and complex structure have been identified as the major limitations of those devices. Such limitations, in addition to complex steps for device to image registration have prevented widespread implementation of MRI-guided prostate biopsy despite the advantages of MRI compared to TRUS. We have designed a compact MRI-guided robotic intervention with the capability to have angulated insertion to avoid damage to any anatomical feature along the needle path. The system consists of a novel mechanism driven Robotic Needle Guide (RNG). The RNG …
A Phenomenological Study Of The Experiences Of Successful Women In Science Fields, Jonathan Hall
A Phenomenological Study Of The Experiences Of Successful Women In Science Fields, Jonathan Hall
Electronic Theses and Dissertations
Girls and women face several forms of gender-based biases and discrimination in the science community. These issues create difficult circumstances for them to develop positive science identities. Since these difficult circumstances exist, science education and sociology researchers have used a deficit model to learn about their experiences, achievements, and attitudes. Understanding the experiences of successful women in science offers insight into how women can navigate the challenges presented by the science community and how science educators can support them. However, research studies that explore the experiences of successful women in science are scant. Therefore, the objective of this study was …

App-Ily Ever After - Self-Presentation And Perception Of Others On The Dating App Tinder, Johnathan Dunlop
Electronic Theses and Dissertations
Location-based real-time dating (LBRTD) apps have become an increasingly common way for people to broaden their social network and meet others for the purposes of dating, friendship, and more. This investigation focused on Tinder, presently the most widely-used LBRTD app. Semi-structured interviews were conducted with twenty-three current and recent Tinder users to gain insight into their self-presentation strategies and impressions of others on the app. The questions concentrated around four major topic areas: use of photos, use of bio text, perception of others, and real or imagined deception. A grounded theory approach was used to frame the data. From this, …
Role Of Single Nucleotide Polymorphisms (Snps) In Ptpn2/22 And Mycobacterium Avium Subspecies Paratuberculosis (Map) In Rheumatoid Arthritis And Crohn's Disease, Robert Sharp
Electronic Theses and Dissertations
Both genetic pre-disposition and potential environmental triggers are shared between Rheumatoid arthritis (RA) and Crohn's disease (CD). We hypothesized that single nucleotide polymorphisms (SNPs) in the negative T-cell regulators Protein Tyrosine Phosphatase Nonreceptor type 2 and 22 (PTPN2/22) lead to a dysregulated immune response as seen in RA and CD. To test the hypothesis, peripheral leukocytes samples from 204 consented subjects were TaqMan genotyped for 9 SNPs in PTPN2/22. The SNPs effect on PTPN2/22 and IFN-y expression was determined using RT-PCR. Blood samples were analyzed for the Mycobacterium avium subspecies paratuberculosis (MAP) IS900 gene by nPCR. T-cell proliferation and response …
Cavity-Coupled Plasmonic Systems For Enhanced Light-Matter Interactions, Abraham Vazquez-Guardado
Cavity-Coupled Plasmonic Systems For Enhanced Light-Matter Interactions, Abraham Vazquez-Guardado
Electronic Theses and Dissertations
Light-matter interaction is a pivotal effect that involves the synergetic interplay of electromag- netic fields with fundamental particles. In this regard localized surface plasmons (LSP) arise from coherent interaction of the electromagnetic field with the collective oscillation of free electrons in confined sub-wavelength environments. Their most attractive properties are strong field en- hancements at the near field, highly inhomogeneous, peculiar temporal and spatial distributions and unique polarization properties. LSP systems also offer a unique playground for fundamental electromagnetic physics where micro-scale systemic properties can be studied in the macro-scale. These important properties and opportunities are brought up in this work …
Necessary Conditions For Open-Ended Evolution, Lisa Soros
Necessary Conditions For Open-Ended Evolution, Lisa Soros
Electronic Theses and Dissertations
Evolution on Earth is widely considered to be an effectively endless process. Though this phenomenon of open-ended evolution (OEE) has been a topic of interest in the artificial life community since its beginnings, the field still lacks an empirically validated theory of what exactly is necessary to reproduce the phenomenon in general (including in domains quite unlike Earth). This dissertation (1) enumerates a set of conditions hypothesized to be necessary for OEE in addition to (2) introducing an artificial life world called Chromaria that incorporates each of the hypothesized necessary conditions. It then (3) describes a set of experiments with …

Reproductive Rights And Justice Advocacy In Central Florida: Who Is Represented?, Mary Hager
Electronic Theses and Dissertations
This thesis examines the racial understanding and social relationships of Planned Parenthood of Southwest and Central Florida staff and volunteers. As well, this research explores how Planned Parenthood supporters organize and promote diverse advocacy work to promote reproductive justice in social media and volunteer education. Planned Parenthood has been at the forefront of reproductive rights campaigns for over a century, and their work has often tied into contemporary feminist and political issues. Of note, feminists of color have called for a shift from advocacy for "reproductive choice" to "reproductive justice" as a way to identify the needs and predicaments of …
Polyelectrolyte Complexes Based On Poly(Acrylic Acid): Mechanics And Applications, Xiaoyan Lu
Polyelectrolyte Complexes Based On Poly(Acrylic Acid): Mechanics And Applications, Xiaoyan Lu
Electronic Theses and Dissertations
Poly(acrylic acid) (PAA) is a weak polyelectrolyte presenting negative charge at basic condition when the carboxylic group loses a proton. These carboxylate group can interact with polycations and metal ions to form stable polyelectrolyte complexes (PECs), leading to tunable properties and multifunctional nanoscale structures through chemical reactions. This research focuses on nanofiber and nanoparticle fabricated by PAA-based PECs. We demonstrated the effect of ferric ion concentration on the mechanical properties of PAA-based single naonofiber by using dark field microscopy imaging and persistence length analysis. The application of PAA-based nanofiber mats loaded with MnO2 for supercapacitors was also explored. As a …
College Student Attitudes Towards Free Speech And Expression, David Oglethorpe
College Student Attitudes Towards Free Speech And Expression, David Oglethorpe
Electronic Theses and Dissertations
Throughout its storied history, higher education in the United States has dealt with the challenges of free speech. From Harvard's 1766 'bad butter riot' to hateful speech directed towards students by non-university community members, balancing the need for free speech with maintaining a welcoming and inclusive campus environment stands as an immense test for higher education (Papandrea, 2017). Idealism and ethicality aside, lost in the academic debate over liberty and protections are the views of those who should best help shine a light on such a divisive issue: students. This dissertation creates a quantitative path to understanding those very viewpoints. …
Coming To A Full Stop: An Investigation Of Menstrual Period Stigmas In College Students, Mary Jane O'Toole
Coming To A Full Stop: An Investigation Of Menstrual Period Stigmas In College Students, Mary Jane O'Toole
Electronic Theses and Dissertations
The focus of this study was to understand perceptions college students have regarding menstruation and if viewing a normalized media message may influence these perceptions. A treatment group of participants was randomly assigned to view an episode of the hit family sitcom Blackish that focused on menstruation and then answer survey questions. A control group of participants only answered the survey questions. A mixed methods analysis revealed three primary conclusions. First, these results contradict existing research in that the college students surveyed generally do not hold negative perceptions that may stigmatize menstruation. Second, the treatment that viewed the normalized media …
Learning Spaces Are Wac: Investigating How Classroom Space Design Influences Student Disciplinary Identities, Landon Berry
Learning Spaces Are Wac: Investigating How Classroom Space Design Influences Student Disciplinary Identities, Landon Berry
Electronic Theses and Dissertations
This dissertation used classroom observations, movement mapping, instructor interviews, and student focus groups to examine the ways in which both instructors and students navigated the classroom spaces they were assigned in upper-level, discipline-specific courses. By focusing on three diverse disciplines (writing and rhetoric, education, and chemistry), this dissertation makes arguments about how the design of classroom spaces (as well as the tools that are housed therein) support, facilitate, and detract from a student's ability to develop a disciplinary identity, which is defined here as the social and linguistic construction of a practitioner of a discipline that is shaped by the …
Animals Of The Cloud Forest: Isotopic Variation Of Archaeological Faunal Remains From Kuelap, Peru, Samantha Michell
Animals Of The Cloud Forest: Isotopic Variation Of Archaeological Faunal Remains From Kuelap, Peru, Samantha Michell
Electronic Theses and Dissertations
Stable isotopic analyses of faunal remains are used as a proxy for reconstructing the ancient Chachapoya dietary environment of the northeastern highlands in Peru. Archaeologists have excavated animal remains from refuse piles at the monumental center of Kuelap (AD 900-1535). This archaeological site is located at 3000 meters above sea level (m.a.s.l.), where C3 plants dominate the region. The study presented here is one of the few in the Central Andes that uses faunal remains to develop local isotopic baselines, reconstruct resource exploitation, and provide insight into dietary variation. Bone collagen stable carbon (δ13C) and nitrogen (δ15N) isotopes are used …
Development Of A Non-Human Primate Model For Staphylococcus Aureus Nasal Carriage, Amanda Lasseter
Development Of A Non-Human Primate Model For Staphylococcus Aureus Nasal Carriage, Amanda Lasseter
Electronic Theses and Dissertations
Staphylococcus aureus nasal carriage (SANC) is largely asymptomatic, but presents a risk of autoinfection and dissemination to new immunocompromised hosts. SA disease states range from mild cutaneous infections to life-threatening bacteremia. Historically utilized rodent models do not naturally carry SA in the nose, are insufficient in longitudinal SANC experimentation, and lack immune factors that are vital in human clearance of SA. The nasal passages of non-human primates are similar anatomically and histologically, and reproductive mucosal studies have shown similar immune responses to pathogens and human-relevant microbial profiles. Seventeen captive pigtailed macaques (Macaca nemestrina) were found to naturally carry SA in …
Machine Learning Methods For Flow Cytometry Analysis And Visualization, Emily Sassano
Machine Learning Methods For Flow Cytometry Analysis And Visualization, Emily Sassano
Electronic Theses and Dissertations
Flow cytometry is a popular analytical cell-biology instrument that uses specific wavelengths of light to profile heterogeneous populations of cells at the individual level. Current cytometers have the capability of analyzing up to 20 parameters on over a million cells, but despite the complexity of these datasets, a typical workflow relies on subjective labor-intensive manual sequential analysis. The research presented in this dissertation provides two machine learning methods to increase the objectivity, efficiency, and discovery in flow cytometry data analysis. The first, a supervised learning method, utilizes previously analyzed data to evaluate new flow cytometry files containing similar parameters. The …

The Evolution Of Peristenus (Hymenoptera: Braconidae): Taxonomy, Phylogenetics And Ecological Speciation, Yuanmeng Zhang
Electronic Theses and Dissertations
Parasitoid wasps are ecologically and economically important as biological control agents. However, little is known about the diversity, distribution and biology of most hymenopteran parasitoids due to their small size, morphological conservatism, and complex life styles. The focus of my PhD research was to investigate the evolution and speciation of euphorine braconid wasps, using a combination of multilocus phylogenetics and population genomic techniques combined with traditional taxonomy. The three data chapters of my dissertation are divided into different taxonomic ranks of euphorine braconids, focusing on genera, species, and populations. For chapter 2, I built a multilocus phylogeny of the tribe …
Countering The Narrative: Exploring The Relationships Among Wellness, Resilience, And Empowerment Within Black Men Who Have Sex With Men Living With Hiv (Bmsm+), Nevin Heard
Electronic Theses and Dissertations
The HIV epidemic continues to disproportionately impact marginalized populations, where one in two Black men who have sex with men (BMSM) will be diagnosed with HIV in their lifetime. The lack of research regarding the wellness of Black men who have sex with men living with HIV (BMSM+) inhibits understanding, which could hinder professions missioned with bettering the wellness of BMSM+. Consequently, the purpose of this study was to investigate if resilience and empowerment predict BMSM+'s wellness. However, a lack of internal consistency among the empowerment measurement required the researcher to remove the scale and adjust the scope of the …

Revisiting The Postclassic Burials At Lamanai, Belize: A Second Look At The Unique Ventrally Placed, Legs Flexed Burials., Victoria Izzo
Electronic Theses and Dissertations
Analysis of unique mortuary patterns is often used to evaluate the social lives of the deceased and also those of the living who placed them there. The Ventrally Placed, Legs Flexed (VPLF) burials at the site of Lamanai in Belize, dating to the Postclassic period (1000 - 1544), have been recorded as a Maya mortuary pattern since the late 1970's. While many researchers have analyzed these skeletal remains, comprehensive and cumulative individual analysis of the VPLF individuals from Lamanai has not been conducted. In this study, I will argue that the VPLF individuals in this study were local to Lamanai, …
Testing The Capability Of Close-Range Photogrammetry To Document Outdoor Forensic Scenes With Skeletal Remains Using Mock Scenarios, Kevin Gidusko
Testing The Capability Of Close-Range Photogrammetry To Document Outdoor Forensic Scenes With Skeletal Remains Using Mock Scenarios, Kevin Gidusko
Electronic Theses and Dissertations
More rigorous methodological protocols are needed to document outdoor forensic scenes containing skeletal remains. However, law enforcement protocols rarely provide specific guidelines for processing these scenes. Regardless, the need to preserve contextual information at crime scenes is of paramount importance and it is worth exploring new technological applications that will allow for better documentation. Close-range photogrammetry (CRP) is one option for outdoor scene documentation, more prominently utilized in archaeological contexts, that may provide forensic archaeologists with a tool to better document these scenarios via 3D modeling. To test the efficacy of CRP as documentation tool three mock scenarios representing common …
Embryonic Stem Cell Derived Exosomes Enhance Cardiac Stem Cell Differentiation Into Heart Cells, Jamillah Hammond
Embryonic Stem Cell Derived Exosomes Enhance Cardiac Stem Cell Differentiation Into Heart Cells, Jamillah Hammond
Electronic Theses and Dissertations
Transplantation of embryonic stem (ES) cells into the ischemic and infarcted heart has proven to repopulate cardiac cell populations, attenuate structural cardiac remodeling, and rescue cardiac function. Unfortunately, the pluripotency of ES cells increases risk of teratoma formation in vivo. Exosomes, smaller in comparison to ES cells, are cell free carriers of miRNA, proteins, and lipids, and do not suggest risk of teratoma formation. Exosomes have been proposed to mediate and attenuate regeneration following myocardial infarction (MI), however, the role of exosomes derived from ES cells (ES-Exo) in activating resident cardiac stem cells (CSCs) to undergo cardiac differentiation is not …
Childhood Experiences And Domestic Violence: The Role That Interpartner Violence Plays In Relationship Functioning And Parenting Behaviors In Adulthood., J'Nelle Stephenson
Childhood Experiences And Domestic Violence: The Role That Interpartner Violence Plays In Relationship Functioning And Parenting Behaviors In Adulthood., J'Nelle Stephenson
Electronic Theses and Dissertations
It is estimated that approximately 25% of women and 7.6% of men report experiencing violence from their romantic partner during their lifetime. Additionally, in households where interpartner violence occurs, there are between 3.3 and 10 million children in the United States alone. It is important to understand the cycle of domestic violence that can occur, as it can inform us about expected outcomes across time. This study examined mothers' childhood exposure to their own parents' domestic violence. It was hypothesized that childhood exposure to domestic violence would be related to unhealthy intimate relationships and to the development of maladaptive parenting …
Gender And Conflict In Long-Term Romantic Relationships, Emily Hamlin
Gender And Conflict In Long-Term Romantic Relationships, Emily Hamlin
Electronic Theses and Dissertations
Conflict is inevitable, but not inherently negative. All relationships face conflict with some frequency and long-term romantic partnerships are no exception. This exploratory qualitative study investigated conflict types, approaches, and affective components using digital conflict journals. Participants logged their relational conflict for one month in order to gain insight into the communication practices and conflict perceptions of couples. A conflict cycle and sensemaking framework was applied to identify patterns and best practices.
Evolution And Distribution Of Phenotypic Diversity In The Venom Of Mojave Rattlesnakes (Crotalus Scutulatus), Jason Strickland
Evolution And Distribution Of Phenotypic Diversity In The Venom Of Mojave Rattlesnakes (Crotalus Scutulatus), Jason Strickland
Electronic Theses and Dissertations
Intraspecific phenotype diversity allows for local adaption and the ability for species to respond to changing environmental conditions, enhancing survivability. Phenotypic variation could be stochastic, genetically based, and/or the result of different environmental conditions. Mojave Rattlesnakes, Crotalus scutulatus, are known to have high intraspecific venom variation, but the geographic extent of the variation and factors influencing venom evolution are poorly understood. Three primary venom types have been described in this species based on the presence (Type A) or absence (Type B) of a neurotoxic phospholipase A2 called Mojave toxin and an inverse relationship with the presence of snake venom metalloproteinases …
A Lesbian, Gay, Bisexual And Transgender + Student Support Group Within A Central Florida State College: A Qualitative Study, Remy Ansiello
A Lesbian, Gay, Bisexual And Transgender + Student Support Group Within A Central Florida State College: A Qualitative Study, Remy Ansiello
Electronic Theses and Dissertations
For decades, lesbian, gay, bisexual, and transgender (LGBT) + students attending institutions of higher education have been marginalized and have experienced hostility and outright discrimination, causing the need for student support groups for this population on college campuses. Recent laws passed at a national level have brought a greater level of equality to this minority group; however, feelings of marginalization, homophobia, heterosexism, and heteronormative culture persist. Therefore, the purpose of this study was to ask how students participating in an LGBT + support group within a Central Florida public state college perceive their experiences in college. The researcher also asked …

In Situ Treatment Systems For Remediation Of Polychlorinated Biphenyl-Contaminated Building Materials, Adibah Almutairi
In Situ Treatment Systems For Remediation Of Polychlorinated Biphenyl-Contaminated Building Materials, Adibah Almutairi
Electronic Theses and Dissertations
Polychlorinated Biphenyls (PCBs) are a family of synthetic organohalides comprising 209 congeners which were used historically as additives in paint and caulking materials over a span of many years. Even though the production of PCBs in the USA has been banned since the late 1970s, their former prevalence and widespread use means many structures are still coated with PCB-laden paints. In addition, the presence of PCBs in elastic sealants has resulted in transport of PCBs into concrete structures and has caused soil contamination around buildings. PCB-contaminated building materials have become a significant concern for the environment and building occupants due …

Influence Of Chitosan-Alginate Scaffold Stiffness On Bone Marrow Stromal Cell Differentiation, Isabel Arias Ponce
Influence Of Chitosan-Alginate Scaffold Stiffness On Bone Marrow Stromal Cell Differentiation, Isabel Arias Ponce
Electronic Theses and Dissertations
Tissue grafts are the gold standard for replacing large volume tissue defects. Yet, they present several risks, including infection, low functional outcomes, and reduced graft integrity. Tissue engineering (TE) combines cells and biomaterial scaffolds to foster tissue growth and remodeling. Bone marrow stromal cells (BMSCs) have been shown to respond to the stiffness of their microenvironment, resulting in differentiation into different lineages. 3D porous chitosan-alginate (CA) scaffolds have been previously demonstrated for bone TE with osteoblasts and BMSCs; however, only a single scaffold composition (4 wt%) was studied. Three CA scaffold compositions (2, 4, 6 wt% CA) were produced. Scanning …
