Fluoresence Spectra Study Of Sterically Strained Isomers Of C24h14 Polycyclic Aromatic (Pahs) & Characterization Of A Bio-Sourced, Fluoresent, Ratiometric Ph Indicator With Alkaline Pka, Samar Abd Alelah

Electronic Theses and Dissertations, 2020-2023

This thesis is composed to two studies, each of which relies on recent advances in time-dependent density functional theory (TD-DFT) to accurately model fluorescence spectra. The first study focuses on evaluating the fluorescence spectrum of polycyclic aromatic hydrocarbons (PAHs) having a molecular weight of 302. Three isomers are analyzed including dibenzo[a,j]fluoranthene, dibenzo[a,k]fluoranthene and dibenzo[a,l]fluoranthene. These isomers differ in the placement of one of six aromatic rings and in the amount that each molecule deviates from planarity. The TD-DFT methods are used to compute spectra in an environment that simulates solvent (n-hexane). These computed spectra are compared to vibronically resolved experimental …


The Troupes Coloniales: A Comparative Analysis Of African American And French Colonial Soldiers In The First World War, Matthew Patsis Jan 2020

The Troupes Coloniales: A Comparative Analysis Of African American And French Colonial Soldiers In The First World War, Matthew Patsis

Electronic Theses and Dissertations, 2020-2023

This thesis examines the service of African American soldiers during World War I in comparison with the service of French Colonial soldiers from Africa. This thesis argues that African Americans existed as colonial subjects of the American Empire and served as the colonial army of the United States just as soldiers from Africa did for France. The scope of this thesis covers ideologies of race in the United States and France, as well as racial policy and the implementation of racial hierarchy within the French and American armies during World War I. Through comparative analysis, this research reveals the relationship …


Deeper Impressions Of Thomas Nast And Joseph Keppler: Analyzing The Role Of Political Cartoons In The Development And Perceptions Of Late Nineteenth Century Group Images, Timothy Dorsch Jan 2020

Deeper Impressions Of Thomas Nast And Joseph Keppler: Analyzing The Role Of Political Cartoons In The Development And Perceptions Of Late Nineteenth Century Group Images, Timothy Dorsch

Electronic Theses and Dissertations, 2020-2023

This paper analyzes political cartoons from Thomas Nast and Joseph Keppler from the late 1860s through the mid-1880s. It argues that through use of effective symbolism and memorable illustrations, these cartoonists created and popularized caricatures of politicians, laborers, Irish Catholics, African Americans, and women that validated stereotypical views of the late nineteenth century and influenced later historical interpretations of the era. Analyzing the Nast and Keppler cartoons as significant historical resources rather than as interesting illustrations for historical monographs reveals the layers of literacy, social and political thought present in the drawings that the readers of the day would have …


Masters Of The Manipulator? A Species Description And Comparative Genomics Study Of Two New Hyperparasites Of The Zombie Ant Fungus, Brittany Lebert Jan 2020

Masters Of The Manipulator? A Species Description And Comparative Genomics Study Of Two New Hyperparasites Of The Zombie Ant Fungus, Brittany Lebert

Electronic Theses and Dissertations, 2020-2023

Fungal hyperparasites have been known to indirectly impact ecosystem composition and disease dynamics by modulating the population size and transmission of their parasite host. In the present study we formally describe two new hyperparasite species that infect the fungus Ophiocordyceps camponoti-floridani, which manipulates the behavior of the Florida carpenter ant. Phylogenetic analyses demonstrate that both fungal hyperparasites are new, distinct species. The unique morphology and phylogenetic placement of one of the species even supports its placement in a new genus, which we have named Niveomyces. Our field data suggests that both new species, Polycephalomyces oviedoensis and Niveomyces ophiocordycipitis, negatively impact …


Reading Between The Lines: Language Ideologies And Tutor Education Readings, Michele Cintron Toney Jan 2020

Reading Between The Lines: Language Ideologies And Tutor Education Readings, Michele Cintron Toney

Electronic Theses and Dissertations, 2020-2023

Language difference and socially-just writing center praxis have long been points of discussion within writing center scholarship. Writing center administrators and tutors recognize that the praxis within their writing centers does not always correspond to their beliefs about working with student writers or the role of the writing center within the academy—particularly in the areas of language equality and social and racial justice—and they acknowledge the impact that course readings have in tutor education. While tutor education readings may not specifically state a particular ideological viewpoint regarding language difference, their discussions of language and rhetorical practices, multilingual writers, and tutoring …


Naming More Of What We Know: Critical Memoirs & The Ecological Metaphor As A Threshold Concept In Writing, Loren Cooper Jan 2020

Naming More Of What We Know: Critical Memoirs & The Ecological Metaphor As A Threshold Concept In Writing, Loren Cooper

Electronic Theses and Dissertations, 2020-2023

"Naming More of What We Know: Critical Memoirs & the Ecological Metaphor as a Threshold Concept in Writing" contributes to the work begun by Adler-Kassner and Wardle to gather and name Writing Studies' body of disciplinary knowledge as "threshold concepts." This thesis answers their call to engage in the ongoing development of threshold concepts by offering an additional critical construct: Writing as ecological. To explicitly acknowledge that writing is ecological is an essential addition to the content of our knowledge because it (1) meets the threshold-concept criteria adapted from Meyer and Land (2003), (2) establishes a codified, embodied, 3-dimensional system …


Unexplored Conceptions: What Writing Center Tutors Think About Writing, Andrew Petrykowski Jan 2020

Unexplored Conceptions: What Writing Center Tutors Think About Writing, Andrew Petrykowski

Electronic Theses and Dissertations, 2020-2023

Writing center tutors enact their conceptions of writing in every tutoring session, and yet their conceptions of writing have not yet been systematically researched. This thesis researches the conceptions of writing of writing center tutors at the University of Central Florida's University Writing Center. To uncover tutors' conceptions of writing, I interviewed three tutors by asking them open-ended questions about their experiences with writing and tutoring. After coding and analyzing the transcripts of these interviews, I found seven shared conceptions of writing. These conceptions are the basis of my argument. Because these conceptions are shared but not taught, I turn …

Characterization Of Clear Coat And Base Coat Automotive Paint Analysis Using Dart-Hrms And Comparison Of Ftir Spectroscopy, Py-Gc-Ms, And Dart-Hrms For Clear Coat Analysis, Kaitlin Jones

Electronic Theses and Dissertations, 2020-2023

Current techniques used to analyze automotive paint samples include microscopy, fourier – transform infrared (FTIR) spectroscopy, and pyrolysis gas chromatography - mass spectrometry (Py-GC-MS). These techniques are performed in the respective order listed above. Out of the three techniques currently used in this field, the one that has the highest discriminatory power is py-GC-MS; however, this technique is time consuming and destructive toward the sample. One hundred automotive paint samples were analyzed using FTIR, Py-GC-MS and direct analysis in real time-high resolution mass spectrometry (DART-HRMS) to determine how DART-HRMS compared to Py-GC-MS in terms of discriminatory capability. DART-HRMS takes approximately …


Estimation And Clustering In Block Models, Majid Noroozi Jan 2020

Estimation And Clustering In Block Models, Majid Noroozi

Electronic Theses and Dissertations, 2020-2023

Networks with community structure arise in many fields such as social science, biological science, and computer science. Stochastic block models are popular tools to describe such networks. For this reason, in this dissertation which is composed of two parts we explore some stochastic block models and the relationship between them. In the first part of the dissertation, we study the Popularity Adjusted Block Model (PABM) and introduce its sparse case, the Sparse Popularity Adjusted Block Model (SPABM). The SPABM is the only existing block model which allows to set some probabilities of connections to zero. For both the PABM and …


Marijuana Use Among Adults In The United States: Comparing Correlates Of Use, Assessing Impact Of Education, And Evaluating Use And Health Amid Justice-Involved Populations, Corey Pomykacz Jan 2020

Marijuana Use Among Adults In The United States: Comparing Correlates Of Use, Assessing Impact Of Education, And Evaluating Use And Health Amid Justice-Involved Populations, Corey Pomykacz

Electronic Theses and Dissertations, 2020-2023

Over the past two decades, there have been significant changes in state-level policies (i.e., decriminalization, medicalization, legalization) in the U.S. regarding marijuana use. Prior research has found a relationship between marijuana policies and decreased perceived risk as well as increased prevalence of use. In light of these historical shifts, the public health implications of marijuana use deserve increased attention by researchers so that we can discern patterns of use, evaluate risk, and inform intervention. This dissertation has three aims: (1) investigate how correlates of use prevalence versus use frequency vary; (2) offer a theoretical explanation as to why more education …


Molecular And Phenotypic Diversification Of A Cryptic Group Of Terrestrial Frogs From The Southern Andes Of Ecuador, Veronica Urgiles Penafiel Jan 2020

Molecular And Phenotypic Diversification Of A Cryptic Group Of Terrestrial Frogs From The Southern Andes Of Ecuador, Veronica Urgiles Penafiel

Electronic Theses and Dissertations, 2020-2023

The Ecuadorean Andes sustains one of the most remarkable frog diversifications. In this region, nearly one in three known species of amphibians belong to the Pristimantis genus, which contains the majority of the direct-developing terrestrial frog species. Although efforts are ongoing to understand the diversity of Pristimantis, large regions of the ecosystems they occupy remain understudied, and speciation and diversity of this genus remains poorly understood. Within this context, an interesting taxon with many unresolved questions regarding patterns and process of diversification is the Pristimantis orestes species complex which is distributed across the Paramo landscape and montane forests in the …


Does One Bad Phish Spoil The Whole Email Load?: Exploring Phishing Susceptibility Task Factors And Potential Interventions, Dawn Sarno Jan 2020

Does One Bad Phish Spoil The Whole Email Load?: Exploring Phishing Susceptibility Task Factors And Potential Interventions, Dawn Sarno

Electronic Theses and Dissertations, 2020-2023

Phishing emails have become a prevalent cybersecurity threat for the modern email user. Research attempting to understand how users are susceptible to phishing attacks has been limited and hasn't fully explored how task factors influence accurate detection. Even further lacking are the existing training interventions that still have users falling victim to up to 90% of phishing emails following training. The present studies examined how task factors (e.g., email load, phishing prevalence) and a new form of intervention, rather than training, influence email performance. In four experiments, participants classified emails as either legitimate or not legitimate and reported on a …


Working Memory In Children With Attention-Deficit/Hyperactivity Disorder: An Investigation Of Short-Term And Central Executive Memory Components Using Functional Near Infrared Spectroscopy, Samuel Eckrich Jan 2020

Working Memory In Children With Attention-Deficit/Hyperactivity Disorder: An Investigation Of Short-Term And Central Executive Memory Components Using Functional Near Infrared Spectroscopy, Samuel Eckrich

Electronic Theses and Dissertations, 2020-2023

Attention-deficit/hyperactivity disorder (ADHD) is an early onset, highly heritable, chronic neurodevelopmental disorder characterized by underdeveloped/deficient executive functions, particularly those entailing working memory (WM). Substantial research exists documenting WM deficits in pediatric age range ADHD and their relation with adverse learning outcomes; however, relatively little is known concerning the extent to which deficient WM processes reflect underlying deficiencies in hemodynamic functioning (OxyHb). This is the first study to use a movement-tolerant neuroimaging tool—functional Near Infrared Spectroscopy (fNIRS)—to investigate hypothesized prefrontalOxyHb differences between children with ADHD and typically developing (TD) children while they complete memory tasks differing in cognitive processing demands (e.g., …

A Case Study Of The Impact Of The Dplc Model Of Professional Learning On Collective Teacher Efficacy And Organizational Trust In A Middle School, Maria Gaspar

Electronic Theses and Dissertations, 2020-2023

The purpose of this case study was to investigate the relationship between the implementation of the District Professional Learning Community (DPLC) model of professional development and collective teacher efficacy and organizational trust at one middle school in a large urban school district. Data were collected from the following sources: Goddard & Hoy's (2003) CE Scale Form L, Hoy & Tschannen-Moran's (2003) Omnibus-T scale, six additional survey items used to explore teachers' perceptions of the DPLC model's influence on improving student literacy, and semi-structured focus group interviews. A series of analysis of variance (ANOVA) and chi-square tests were performed to analyze …


Understanding And Predicting Properties Of Low-Dimensional Functional Materials From First-Principles, Naseem Ud Din Jan 2020

Understanding And Predicting Properties Of Low-Dimensional Functional Materials From First-Principles, Naseem Ud Din

Electronic Theses and Dissertations, 2020-2023

A periodic network with uniform single metal active site, in coordination with redox-active organic ligands, is a promising class of materials for next generation single atom catalysts. Towards this quest, in this dissertation I have carried out first-principles density functional theory (DFT) based calculations of the geometrical and electronic structure and magnetic properties of several transition-metal-organic-chains (TM-C) both in gas phase as well as on Au(111) surface. Of particular interest are dipyridyltetrazine (DT), Bis-pyrimidine (BP), and 1,10-phenanthroline5,6-dione, (PDO) ligands used to design the TM-C with several single TM atoms as the coordination center. I have screened several TM atoms to …


Symmetry And High Harmonic Spectroscopy In Solids, Shima Gholam Mirzaeimoghadar Jan 2020

Symmetry And High Harmonic Spectroscopy In Solids, Shima Gholam Mirzaeimoghadar

Electronic Theses and Dissertations, 2020-2023

High harmonic generation (HHG) by intense femtosecond laser pulses has, over the last three decades, provided new coherent sources of extreme ultraviolet and soft x-ray light and enabled the field of attosecond science. Furthermore, as properties of the target are encoded in the harmonic emission, high harmonic spectroscopy has allowed extraction of molecular structure and dynamics from the spectra and polarization states of harmonics generated from gas-phase molecules. HHG from solids, discovered in 2011, now promises to offer similar benefits to condensed matter physics. In this dissertation, I describe progress on two fronts: extending attosecond techniques to generate new high …


Novel Roles Of Rip2 In Inflammation And Resolution, Michael Shehat Jan 2020

Novel Roles Of Rip2 In Inflammation And Resolution, Michael Shehat

Electronic Theses and Dissertations, 2020-2023

Receptor-interacting protein 2 (RIP2) is a kinase which mediates signaling downstream of the bacterial peptidoglycan sensors Nucleotide-binding Oligomerization Domain (NOD) 1 and 2. Genetic loss or pharmaceutical inhibition of RIP2 has been shown to be beneficial in multiple inflammatory disease models with the effects largely attributed to reducing pro-inflammatory signaling downstream of peptidoglycan recognition. However, given the widespread expression of this kinase and its reported interactions with numerous other proteins, it is possible that RIP2 has many other unappreciated roles. In this work, we report the involvement of RIP2 in two novel pathways. First, we demonstrate a NOD2 dependent role …


Improving Air Pollution Exposure Estimation Using Cell Phone Location Data And Low-Cost Sensors, Xiaonan Yu Jan 2020

Improving Air Pollution Exposure Estimation Using Cell Phone Location Data And Low-Cost Sensors, Xiaonan Yu

Electronic Theses and Dissertations, 2020-2023

Human exposure estimation to air pollution plays an important role in epidemiological studies which are designed to reveal correlations between human exposures to certain air pollutants and certain diseases, such as asthma, cardiovascular disease and reproductive diseases. Traditionally, when people's mobile data is hard to get, home location is used to estimate people's exposures assuming that people stay at home all the time. Whereas, people move and it is more accurate to estimate people's exposures including people's mobility. In our study, we showcased two methods to obtain people's mobile data: Google Maps location history (GMLH) data and Call Detailed Record …


Metatheatre And Critical Race Theory: A Combination For Compelling Storytelling And Effective Changemaking, Andrew Coleburn Jan 2020

Metatheatre And Critical Race Theory: A Combination For Compelling Storytelling And Effective Changemaking, Andrew Coleburn

Electronic Theses and Dissertations, 2020-2023

Vaclav Havel once said that "[t]heatre is always a sensitive seismograph of an era, perhaps the most sensitive one there is; it's a sponge that quickly soaks up important ingredients in the atmosphere around it." One of the more important "ingredients" in our cultural atmosphere in modern America is the issue of identity. In his book on metatheatre, Richard Hornby posits that theatre is "a kind of identity laboratory, in which social roles can be examined vicariously." In this thesis, I examine Hornby's theory of the five different modes of metatheatre, critique each, and argue for the addition of a …

Adaptation Of The Novel "Silas Marner" Into A One-Act Play And Performance, Melaney Douglass

Electronic Theses and Dissertations, 2020-2023

As a teacher of high school theatre, I aspire to create powerful and thought-provoking theatre with my students. For my thesis, I adapted George Eliot's classic novel Silas Marner into a one-act play. I researched the novel and the necessary aspects of writing a one-act play. I explored the overriding themes in the novel. I researched and applied the techniques, skills and literary mechanics necessary to construct a one-act play. I recorded the creative process with my students as we, the director and actors, produced this original one-act for public performances. I reflected on this thesis journey and objectively critiqued …

Simulating Medical Isolation: Communicatively Managing Patient And Medical Team Safety, Elizabeth L. Spradley, R. Tyler Spradley Jan 2020

Simulating Medical Isolation: Communicatively Managing Patient And Medical Team Safety, Elizabeth L. Spradley, R. Tyler Spradley

International Crisis and Risk Communication Conference

Reducing hospital acquired or associated infections (HAIs) is a national public health priority. HAIs pose risks to patients, visitors, and medical personnel. To better understand how to communicatively manage safety in medical isolation, data was collected with nursing students simulating medical isolation in a high-fidelity simulation with a medical mannequin with C. difficile. Observations of nursing students and faculty revealed four distinct communication practices: social support, patient education, humor, and storytelling. Conclusions include recommendations to intentionally design these communication practices into high-fidelity medial isolation simulations and scale up these communication practices in routines of safety.


Is All Publicity Good Publicity? Ask Peloton, Rodney Andrew Carveth Jan 2020

Is All Publicity Good Publicity? Ask Peloton, Rodney Andrew Carveth

International Crisis and Risk Communication Conference

Controversial ad campaigns from companies such as Nike have suggested that “any publicity is good publicity.” This case study of a controversial 2019 advertising campaign by Peloton, where one its ad not only was critically panned, but resulted in Peloton losing nearly $1 billion in market value. The case shows that not only was Peloton tone deaf about the message the company is putting out there, it defended itself by insulting its consumer base.


Public Opinion On Intellectual Property, Danielle K. Buckles Jan 2020

Public Opinion On Intellectual Property, Danielle K. Buckles

Honors Undergraduate Theses

Several studies have tracked the rise in music piracy following the creation of Napster, analyzing the attitudes and behaviors associated. But new developments, such as streaming services and social media, have transformed the relationship between creators and users. This paper seeks to revisit the topic, reexamine past results, and evaluate public opinion in this current technological landscape. Understanding the new attitudes and behaviors associated with illegal music downloading through a questionnaire reveal important implications for the future of intellectual property legislation. These findings give some insight into the perceptions of ownership over intangible property to hopefully improve consumer and industry …


Inter-Rater Reliability And Intra-Rater Reliability Of Synchronous Ultrasound Imaging And Electromyography Measure Of The Lumbopelvic-Hip Muscle Complex, Courtney Caputo Jan 2020

Inter-Rater Reliability And Intra-Rater Reliability Of Synchronous Ultrasound Imaging And Electromyography Measure Of The Lumbopelvic-Hip Muscle Complex, Courtney Caputo

Honors Undergraduate Theses

Objective: The purpose of this study was to determine inter-rater and intra-rater reliability of synchronous ultrasound imaging and electromyography measures of lumbopelvic-hip muscle activity performed by a novice and an experienced investigator in healthy individuals. Electromyography (EMG) has served as the gold standard for quantification of onset of muscle activation; however, ultrasound imaging can visualize muscle activity when collected simultaneously. Methods: A novice and experienced investigator collected a series of 3 ultrasound images at rest and 3 M-mode clips during contraction of each muscle while EMG electrodes collected muscle activity. Muscles collected included: external oblique, erector spinae, rectus abdominis, gluteus …


Development Of An Environmental Disposition Scale: A Guide For Fostering Sustainable Behavior, Jady Chen Jan 2020

Development Of An Environmental Disposition Scale: A Guide For Fostering Sustainable Behavior, Jady Chen

Honors Undergraduate Theses

Promoting sustainable behavior or environmentally responsible behavior poses challenges because there is no overarching solution for behavior changes. Both surveys and interventions are context specific, meaning behaviors do not necessarily influence other behaviors and the same values, norms, and beliefs do not necessarily translate to the same level of sustainable behavior. Because there are regional differences in ideologies in the United States, a country level approach to encourage sustainable behavior would not be as effective as having interventions that directly correlate with the motivations that encourage environmentally responsible behavior. A survey will be conducted with University of Central Florida undergraduate …


Lights, Camera, Inaction: Relationship Management In The Film Industry Following Sexual Misconduct Accusations, Autumn Crouch Jan 2020

Lights, Camera, Inaction: Relationship Management In The Film Industry Following Sexual Misconduct Accusations, Autumn Crouch

Honors Undergraduate Theses

In the wake of the #MeToo movement, how society responds to sexual misconduct allegations has greatly changed. It has had an effect on policy from the federal to the organizational level. Looking at overarching changes that came about after the movement is one thing but taking a look at consequences brought upon certain individuals who had allegations put against them is another. This thesis explores public relations (PR) strategies executed by prominent individuals in the film industry and their publicity teams following sexual misconduct accusations. PR at its core is about relationship management. So, this line of thought leads one …
