Dynamic Spillovers And Portfolio Implication Between Green Cryptocurrencies And Fossil Fuels, Zaghum Umar, Sun Yong Choi, Tamara Teplova, Tatiana Sokolova

All Works

Are green investments decoupled from the dirty investment such as the fossil fuel markets? We address this issue by extending the literature on environmental, social, and governance (ESG) assets by examining the dynamic relationship between fossil fuels and digital ESG assets proxied by green cryptocurrencies using the TVP-VAR(Time-varying parameter vector auto regression) spillover framework. Furthermore, we analyze the hedging attributes of green cryptocurrencies and fossil fuels in a minimum connectedness framework. The main findings are as follows: First, green cryptocurrencies are the main shock transmitters in all asset systems. Second, the dynamic connectedness between green cryptocurrencies and fossil fuels increased …

2-Uniform Covering Groups Of Elementary Abelian 2-Groups, Dana Saleh, Rachel Quinlan

All Works

This article is concerned with the classification of Schur covering groups of the elementary abelian group of order (Formula presented.), up to isomorphism. We consider those covering groups possessing a generating set of n elements having only two distinct squares. We show that such groups may be represented by 2-vertex-colored and 2-edge-colored graphs of order n. We show that in most cases, the isomorphism type of the group is determined by that of the 2-colored graph, and we analyze the exceptions.

Me And My Baby: Directing & Designing "Chicago" At The High School Level, Leo Arteche Arencibia

Electronic Theses and Dissertations, 2020-2023

Directing a musical production in a high school setting under normal circumstances is a challenging undertaking – doing so in the throes and aftermath of a global pandemic, with its school closures, quarantines and general chaos, was an exercise in patience and creativity. For my Master's Thesis, I directed and designed a production of Chicago at Miami Arts Charter School, a performing arts high school in the Wynwood arts district, where I have taught for twelve years and served as the Theatre Director for the past eight years. Chicago made perfect sense as the first "post-pandemic" production. First, it is …

Two Essays On Esg, Natalya Bikmetova

Electronic Theses and Dissertations, 2020-2023

My dissertation studies the potential for the increased importance of Environmental, Social, and Governance (ESG) information for corporations and investors in the U.S. market. In my first essay, I examine the effect of coverage by ESG rating agencies on firm ESG performance and disclosure policy. To control for the selection in coverage, I construct a sample of firms with existing ESG ratings from some agencies and study the marginal effect of an additional coverage on a firm relative to firms that did not receive the additional coverage. I find that when firm ESG coverage intensifies, its ESG ratings improve, its …

Topographical Distribution And Morphology Of Sympathetic Postganglionic Innervation And Chronic Intermittent Hypoxia (Cih) Induced Remodeling Of The Whole Heart At Single Cell/Axon/Varicosity Scale, Ariege Bizanti

Electronic Theses and Dissertations, 2020-2023

The sympathetic nervous system is crucial for controlling multiple cardiac functions and its overactivity is associated with many cardiovascular diseases (CVD). Chronic intermittent hypoxia (CIH) is a current model for sleep apnea, which constitutes a major risk factor for CVD through sympathetic overactivity. However, a comprehensive neuroanatomical map of the sympathetic innervation of the heart is unavailable which impedes our understanding of the remodeling of this map in pathological conditions. First, we used a combination of state-of-the-art techniques, including flat-mount tissue processing, immunohistochemistry for tyrosine hydroxylase (TH, a sympathetic marker), confocal microscopy and Neurolucida 360 software to trace, digitize, and …

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 …

Music Direction And Piano Accompaniment In Musical Theatre: A Practical Guide, Danielle Hayes

Electronic Theses and Dissertations, 2020-2023

Music direction for musical theatre is not a topic that has been widely theorized, defined, or researched; there are a handful of resources available to the inclined reader, and a scant few universities that offer a degree in Music Direction for Musical Theatre. Due to this, many music directors, myself included, have had to piece together our educations á la carte, researching each aspect of the job individually. Thus, I have created a practical "how to" guide that can be used to advance you, the reader, through a production as the music director from booking the gig to closing night. …

Flow Theory In The Actor's Process: Can The Pursuit Of Optimal Experience Alleviate Anxiety?, Kimberly (Kimber) King

Electronic Theses and Dissertations, 2020-2023

Using techniques from acting scholars and practitioners, this practice as research study seeks to lesson anxiety in actors by measuring the actor's preparation, rehearsal and performance process against each of Mihaly Csikszentmihalyi's conditions of flow. Csikszentmihalyi's flow theory describes flow as an "optimal experience" in which a person is so invested in their goals, there is "no threat for the self to defend against" (M. Csikszentmihalyi 76). His research identified conditions that when present, can induce a state of flow. However, actors can be plagued by negative thoughts and self-consciousness. While a certain amount of anxiety is expected and normal, …

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 …

Creative Collaborations: An Arts Integrated Educational Business, Michele Perkins

Electronic Theses and Dissertations, 2020-2023

One of the main reasons I have been attracted to the world of theatre is its versatility. Theatre incorporates many other disciplines: Science, Mathematics, History, Language, Philosophy, and Psychology to name a few. I have always had daydreams about running a school program that utilizes a play as the unifying force behind the research and application of traditional academic subject. When I first started as an English teacher, I created many projects that incorporated other disciplines, such as creative writing, acting, and music. When I began teaching theatre, I began to focus solely on skills that applied to theatre. I …

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 …

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 …

Theatrical Intimacy: Navigating A New Normal, Elizabeth Smith-Cortelyou

Electronic Theses and Dissertations, 2020-2023

This thesis explores theatrical intimacy choreography and coordination during current significant social shifts. Covid restrictions, keen awareness of "correctness", and a desire to "do better" have allowed protective practices like theatrical intimacy to become not only generally accepted but expected in rehearsal spaces. Using techniques such as consent-based spaces, actor disclosures, and common language acquired through training with Chelsea Pace and Laura Rikard, the founders of Theatrical Intimacy Education (TIE), I explore choreographing close relationship moments through high school productions of Jane Eyre and Footloose presented in 2021-22 at Lake Highland Preparatory in Orlando and with older BFA/MFA student actors …

Play As A Means Of Connection, Charles Street

Electronic Theses and Dissertations, 2020-2023

This thesis research and practical application focuses on rediscovering the playfulness of the actor's process and evaluating how that translates into an actor's performance. An actor's confidence can be found in their willingness to play with vocal placement, physical tensions, and emotional and mental patterns and depth. As an actor, my definition of play theory is the act of choosing to be spontaneous, creative, and explorative in the process of storytelling to ultimately lead to stronger choices that develop rich connections. Through the lens of play theory, I demonstrate how play affects our mind, emotions, body, and voice. This thesis …

Automated Machine Learning: Intellient Binning Data Preparation And Regularized Regression Classfier, Jianbin Zhu

Electronic Theses and Dissertations, 2020-2023

Automated machine learning (AutoML) has become a new trend which is the process of automating the complete pipeline from the raw dataset to the development of machine learning model. It not only can relief data scientists' works but also allows non-experts to finish the jobs without solid knowledge and understanding of statistical inference and machine learning. One limitation of AutoML framework is the data quality differs significantly batch by batch. Consequently, fitted model quality for some batches of data can be very poor due to distribution shift for some numerical predictors. In this dissertation, we develop an intelligent binning to …

Holographic Recording Of Unslanted Volume Transmission Gratings In Acrylamide/Propargyl Acrylate Hydrogel Layers: Towards Nucleic Acids Biosensing, Paola Zezza, María Isabel Lucío, Izabela Naydenova, María José Bañuls, Ángel Maquieira

Articles

The role of volume hydrogel holographic gratings as optical transducers in sensor devices for point-of-care applications is increasing due to their ability to be functionalized for achieving enhanced selectivity. The first step in the development of these transducers is the optimization of the holographic recording process. The optimization aims at achieving gratings with reproducible diffraction efficiency, which remains stable after reiterative washings, typically required when working with analytes of a biological nature or several step tests. The recording process of volume phase transmission gratings within Acrylamide/Propargyl Acrylate hydrogel layers reported in this work was successfully performed, and the obtained diffraction …

Magnetic Response Of A Two-Dimensional Viscous Electron Fluid, Aydin Cem Keser, Oleg Sushkov

Turkish Journal of Physics

It has been established that the Coulomb interactions can transform the electron gas into a viscous fluid. This fluid is realized in a number of platforms, including graphene and two-dimensional semiconductor heterostructures. The defining characteristic of the electron fluid is the formation of layers of charge carriers that are in local thermodynamic equilibrium, as in classical fluids. In the presence of nonuniformities, whirlpools and nontrivial flow profiles are formed, which have been directly imaged in recent experiments. In this paper, we theoretically study the response of the electron fluid to localized magnetic fields. We find that the electric current is …
