My primary research centers on Ragtime (1897-1918), The Diary of Anne Frank (1939-1945) and The Laramie Project (2002), which deal with racism, anti-Semitism and homophobia, respectively. My intention is to highlight how theatre impacts the ideas and thoughts of audiences and transforms thinking and points of view forever, as well as impacting cultures and our world. In addition, I discuss the historical measures that led to these events and progression in modern times. Music, art and theater are known as Ã‚Â"performing artsÃ‚Â" which enrich our lives and leave us feeling complete. They also have the power to influence people and open minds and hearts to different ways of thinking about the world and its people.

Title: REDEFINING CHOREOGRAPHY FOR THE "THE ROCKY HORROR SHOW" FOR A NEW GENERATION OF ACTORS.
Creator: Ellis, Timothy, Weaver, Earl, University of Central Florida
Abstract / Description: As many veterans of musical theatre strive to keep a stronghold on the traditional form of the art with shows like "Oklahoma," "Show Boat" and "Carousel," we must recognize the life of said art form must also appeal to the mindset of new generations.

Show moreAs many veterans of musical theatre strive to keep a stronghold on the traditional form of the art with shows like "Oklahoma," "Show Boat" and "Carousel," we must recognize the life of said art form must also appeal to the mindset of new generations. In 1973, a rock musical began making waves in London's theatrical community. "The Rocky Horror Show" was like nothing anyone had seen before. The show had a plot but was presented like a rock show. The characters paid homage to a youthful faction of society wanting to express its individualism. Musicals continue to explore new avenues and bring new faces to the theatre. Shows such as "Rent," "Saturday Night Fever" and "Wicked" have garnered interest from a younger audience. Songs from these shows are appealing to the masses just as the songs from "Oklahoma" and "Carousel" did in the 1940's. A growing interest in musical theatre by the younger population can pique their interest in discovering other musicals. One way to satisfy this piqued interest is by infusing a youthful or modern energy to shows that can be adapted to the senses of this younger generation. "Oklahoma" or "Carousel" might not adapt well by being set in the 21st century. But "The Rocky Horror Show" already exudes a timeless energy with its nod to popular culture (its rock music influence). As musical theatre transforms with its audiences, so can some of its well-known shows.

Title: COMPARISON OF SINGLE STAGE AND TWO STAGE STAGE GRID-TIE INVERTERS.
Creator: Mansfield, Keith, Batarseh, Issa, University of Central Florida
Abstract / Description: This thesis compares two methods of designing grid-tie inverters. The first design topology is a traditional two stage approach consisting of an isolated DC-DC converter on the input followed by a high switching frequency SPWM (Sinusoidal Pulse Width Modulation) stage to produce the required low frequency sine wave output. The novel second design approach employs a similar DC-DC input stage capable of being modulated to provide a rectified sine wave output voltage/current waveform. This stage...
Show moreThis thesis compares two methods of designing grid-tie inverters. The first design topology is a traditional two stage approach consisting of an isolated DC-DC converter on the input followed by a high switching frequency SPWM (Sinusoidal Pulse Width Modulation) stage to produce the required low frequency sine wave output. The novel second design approach employs a similar DC-DC input stage capable of being modulated to provide a rectified sine wave output voltage/current waveform. This stage is followed by a simple low frequency switched Unfolding Stage to recreate the required sine wave output. Both of the above designs have advantages and disadvantages depending on operating parameters. The following work will compare the Unfolding Output Stage and the SPWM Output Stage at various power levels and power densities. Input stage topologies are similarly examined in order to determine the best design approach for each output stage under consideration.

Show moreRenewable energy source plays an important role in the energy cogeneration and distribution. Traditional solar-based inverter system is two stages in cascaded, which has a simpler controller but low efficiency. A new solar-based single-stage grid-connected inverter system can achieve higher efficiency by reducing the power semiconductor switching loss and output stable and synchronized sinusoid current into the utility grid. Controlled by the digital signal processor, the inverter can also draw maximum power from the solar array, thereby maximizing the utilization of the solar array. In Chapter 1, a comparison between the traditional two-stage inverter and the single-stage inverter is made. To increase the ability of power processing and enhance the efficiency further, a full-bridge topology is chosen, which applies the phase-shift technique to achieve zero-voltage transition. In Chapter 2, average-mode and switch-mode Pspice simulations are applied. All the features of the inverter system are verified, such as stability, zero voltage transition and feed-forward compensation, etc. All these simulation results provide useful design tips for prototyping. In Chapter 3, a phase-shift controller is designed based on UCC3895. Also, a detailed design procedure is given, including key components selection, transformer and inductor design and driver circuits design. In Chapter 4, experimental results of a prototype DC/DC converter are presented and analyzed. By optimization of the circuit, the problems of the prototype are solved and the prototype is working stably. The thesis' conclusion is given in Chapter 5.

Show moreThe study of stage combat is designed to fabricate the illusion of physical combat without causing harm to the performers. Most research in this field does not take into account the characterization of the actor during the training of a fight scene. An actor primarily learns the stunt choreography of the scene and often times the subtleties of the character is often forgotten. Scenes that involve physical contact are an essential aspect of the dramatic action. My aim is to eventually devise a process that will consistently create fight scenes that maintain the integrity of the fight director's work as well as the mastery of the actor's character composition. I am aware this is an ambitious project therefore will I approach this endeavor in two stages. This document will cover the first stage of this project: the investigation of the current process of several professionals who have varying experiences with fight choreography. I will propose and explore the significance of a series of questions a director, actor and fight choreographer should answer before embarking upon a fight sequence successfully. Questions such as: How important is the stunt physiologically and psychologically on the character? Does gender play a role in a fight sequence? Do size, age, and race play a role on character choice in a sequence? Why did the character choose that weapon? Where did that character learn to fight and why in that style?

Show moreBy the late nineteenth and early twenty century both the United States and Europe were experiencing massive shifts in social organization, social attitudes, and global influence due to the effects of the industrial revolution and imperialistic expansion. This birth of a public sphere and the mass entertainment industry was related to a blurring of the lines between traditional social classes. Mass entertainment's growth was directly related to the need to attract large audiences with entertainment that appealed in some way to a broad spectrum of the populace. At the same time, stage illusionists or magicians were one of the most recognizable stars of mass entertainment. In fact, they were in the midst of what has been termed the (")Golden Age(") of magic. By recognizing the popularity of their performances in the United States and Europe, this thesis will use them as a reflection of historical trends and popular attitudes in areas such as romanticism, secular/technical superiority, race, and gender. Historians, like Lawrence Levine, have produced a number of historical studies in regards to performance art, mass entertainment, and the historical implications represented in entertainment. Previous studies of magicians during the time period have been primarily biographical or technical in nature. It is only recently that historians have begun to combine the two in regards to performance magic. This thesis will combine previous research on the historical narrative of the time from authors such as Leon Fink, Sean Cashman, and Alan Trachtenburg in order to analyze how magical performances confirm conclusions reached by previous work on the historical context of these performances.The themes that are addressed within this work begin with the birth of mass entertainment, the need for an act with mass appeal to attract audiences, and how the mass entertainment displays a blurring of class lines. It will expand on work by Daniel T. Rogers in explaining how these trends were not exclusive to the United States or Europe and were actually a transatlantic phenomenon. It will use Simon During to explain how magicians, with roots in folk culture, became stars on the stage because of their appeal and their unique position in performance art. It will add to work by authors such as Lawrence Levine, showing how magicians needed to perform acts for mass consumption by working class, middle class, and upper class individuals. Finally, it will use magical performances as text to reflect social attitudes of the time period much in the way that authors such as Eric Green or Katherine Prince have done in their work. ?

Show moreIn Spring 2007, the University of Central Florida (UCF) Department of Theatre mounted a production of "The Rocky Horror Show." This thesis focuses on the author's process of using the gospel music style to revitalize "The Rocky Horror Show," a cult musical. The author uses defining characteristics of the cult film genre to establish a set of guidelines. "The Rocky Horror Picture Show" is the movie version of the stage musical and is responsible for the show's inevitable cult status. He discusses the history and journey of "The Rocky Horror Show" and how audience participation was integral in establishing this landmark musical. The reader observes the process used in rearranging "The Rocky Horror Show" score from start to finish and recordings used as influence throughout. Although this is a discussion of a musical process, this portion of the document is written in terms for all to understand, and a glossary of terms is provided for those that are unsure of certain vocabulary. With a show that is well established, one must be careful when making stylistic changes. The author took this into consideration when arranging the score and rationalizes through a discussion of gospel music history, key gospel elements apparent throughout the score, and how the essence of Richard O'Brien's music remains intact.

Show moreThe musical Bernarda Alba tells the story of a woman who is confined within the heavily patriarchal and Catholic society that was 1930s Spain. Because of this, I thought it the perfect arena to explore power dynamics on stage. My thesis will explore status, hierarchies, relationships, and identity via the stolid matriarchal character Bernarda Alba. Through analyzing the playwright's words, fleshing out the character, and exploring the character's relationships with others in rehearsal, I have studied how to activate status on stage. There are many sociology theories and psychological studies that can be applied to theatre-making in order to create fleshed out relationships, characters, and worlds. I have taken these theories into practice, as I battled with my own hierarchies in real life, and I let art and life do what they do best: imitate each other. I will analyze and play with the physical movement and posture of the character, the vocal choices in the delivery of the scripted words, and the psychological choices in the form of subtext and unspoken thought. There is an abundance of agency one holds when creating status and identity for a character, and I break down the different facets to explore. More importantly, outside of the stage, if we realize that status is more intricate and flexible than we think it is, then we as individuals can unlock invaluable freedoms that can unchain us from daily oppression.

Abstract / Description: Axial-staged combustors represent an important concept that can be applied to reduce NOx emissions throughout a gas turbine engine. There are four main CFD models presented in this study that describe a highly turbulent jet-in-crossflow (JIC) simulation of partially premixed and non-premixed jets with a constant chamber pressure of 5 atm absolute.

Show moreAxial-staged combustors represent an important concept that can be applied to reduce NOx emissions throughout a gas turbine engine. There are four main CFD models presented in this study that describe a highly turbulent jet-in-crossflow (JIC) simulation of partially premixed and non-premixed jets with a constant chamber pressure of 5 atm absolute. The equivalence ratio of the partially premixed jet was held constant at rich conditions with a ?_jet of 4 while the main stage varied from ?_1 and ?_2 of 0.575 and 0.73 with an average headend temperature of 1415K and 1545K, respectively. Chemistry was reduced by tabulation of eight main species using the equilibrium calculation of the software Chemkin. The centerline temperatures entering the JIC stage were measured experimentally and used as the starting point of a radial temperature profile that follows a parabolic trend. Comparison between the uniform and radial temperature profiles showed that the latter had a higher penetration depth into the vitiated crossflow due to a direct relationship between temperature and velocity. To capture the combustion process, Flamelet Generated Manifold (FGM) model was used. The progress variable source uses Turbulent Flame Speed Closure (TFC) to calculate flame propagation and position. There are two distinct flame positions of stability, the windward and leeward sides of the jet. The leeward flame positions for the two equivalence ratios showed that the richer condition sits closer to the jet due to the hotter equilibrium temperature; while the windward flame position is shifted upstream for the leaner case due to more availability of oxygen. The total temperature rise for ?_1 = 0.575 and ?_2 = 0.73 are ?T = 239 K and 186 K, respectively. The non-premixed simulations used a Steady Laminar Flamelet (SLF) approach with a headend equivalence ratio of ?_non = 0.6 and a detailed prediction of CH4 usage, CO production, and temperature increase throughout the jet-in-crossflow domain. Methane was shown to be consumed at a high amount, at almost 90% conversion with a temperature rise of ?T = 149 K. The heat release is below the calculated equilibrium ?T with the main reason pointed out that a significant amount of CH4 is only partially oxidized to CO due to limited oxygen availability with a fuel only configuration. Realizable K-Epsilon, SST K-Omega ?-Re?, and Reynolds Stress Transport (RST) turbulence models were used and compared. RST turbulence model showed to over predict the penetration depths and dissipation of the jet in the downstream domain when compared to literature and experimental data.

Show moreThe purpose of this largely qualitative study was to develop a blueprint for planning and designing a staged-authentic heritage tourist attraction for small island nations. Data were gathered and analyzed in three phases. In Phase I, existing and potential supply, demand, and external variables associated with staged-authentic heritage attractions were identified, and a preliminary planning model and conceptual framework was developed. In Phase II, the model was refined. A blueprint containing seven major questions and 26 sequential steps was developed. In Phase III, the blueprint was tested using focus groups and an online tourist survey in the Caribbean region (Aruba) in order to determine the extent to which it could be useful to those responsible for the development of staged-authentic heritage tourist attractions. It was concluded that (a) the devised blueprint is appropriate and effective for planning and designing a staged-authentic heritage attraction for small island nations, (b) the seven questions and 26 steps developed to support the methodological flowchart ensure attention to essential activities and events in the planning and designing of a staged-authentic heritage attraction, and (c) continuous collaboration among all stakeholders is required in planning and designing staged-authentic heritage attractions so as to ensure commitment of those who would be contributors, supporters, and developers of the project. Implications for the use of the blueprint and for staged-authentic heritage attractions were offered. Also presented were recommendations for future research.

Title: Mathematical Modeling of Carbon Removal in the A-Stage Activated Sludge System.

Show moreThis research developed a dynamic activated sludge model (ASM) to better describe the overall removal of organic substrate, quantified as chemical oxygen demand (COD), from A-stage high rate activated sludge (HRAS) systems. This dynamic computer model is based on a modified ASM1 (Henze et al., 2000) model. It was determined early in the project that influent soluble COD, which is normally represented by a single state variable in ASM1, had to be subdivided into two state variables (SBs and SBf, or slow and fast fractions) to simulate the performance of A-stage systems. Also, the addition of state variables differentiating colloidal COD from suspended COD was necessary due to short hydraulic residence times in A-stage systems which do not allow for complete enmeshment and bioflocculation of these particles as occurs in conventional activated sludge systems (which have longer solid retention times and hydraulic retention times). It was necessary to add several processes (both stoichiometry and kinetic equations) to the original ASM1 model including heterotrophic growth on both soluble substrate fractions and bioflocculation of colloidal solids. How to properly quantify heterotrophic growth on SBs and SBf resulted in two separate approaches with respect to process kinetic equations. In one approach the SBf was metabolized preferentially over SBs which was only utilized when SBf was not available. This is referred to as the Diauxic Model. In the other approach SBf and SBs were metabolized simultaneously, and this is referred to as the Dual Substrate Model. The Dual Substrate Model calibrated slightly better than the Diauxic Model for one of the two available pilot studies data sets (the other set was used for model verification). The Dual Substrate A-stage model was used to describe the effects of varying specific operating parameters including solids retention time (SRT), dissolved oxygen (DO), influent COD and temperature on the effluent COD:N ratio. The effluent COD:N ratio target was based on its suitability for a downstream nitrite shunt (i.e. nitritation/denitritation) process. In the downstream process the goal is to eliminate nitrite oxidizing bacteria (NOB) from the reactor while selecting for ammonia oxidizing bacteria (AOB). The results showed that a low SRT ((<)0.25 d) can produce high effluent substrates (SB and CB), and elevated COD:N ratios consistent with NOB out-selection downstream, the HRAS model was able to predict the measured higher fraction of CB in the A-stage effluent at lower SRTs and DO concentrations, and to achieve the benefits of operating an A-stage process, while maintaining an effluent COD:N ratio suitable for a downstream nitritation/denitritation process, an A-stage SRT in the range of 0.1 to 0.25 d should be maintained.This research also included an analysis of A-stage pilot data using stoichiometry to determine the bio-products formed from soluble substrate removed in an A-stage reactor. The results were used to further refine the process components and stoichiometric parameters to be used in the A-stage dynamic computer model, which includes process mechanisms for flocculation and enmeshment of particulate and colloidal substrate, hydrolysis, production of extracellular polymeric substances (EPS) and storage of soluble biodegradable substrate. Analysis of pilot data and simulations with the dynamic computer model implied (indirectly) that storage products were probably significant in A-stage COD removal.

Show moreBase flow recession curve during a dry period is a distinct hydrologic signature of a watershed. The base flow recession analysis for both streamflow and spring flow has been extensively studied in the literature. Studies have shown that the recession behaviors during the early stage and the late stage are different in many watersheds. However, research on the transition from early stage to late stage is limited and the hydrologic control on the transition is not completely understood. In this dissertation, a novel cumulative regression analysis method is developed to identify the transition flow objectively for individual recession events in the well-studied Panola Mountain Research Watershed in Georgia, USA. The streamflow at the watershed outlet is identified when the streamflow at the perennial stream head approaches zero, i.e., flowing streams contract to perennial streams. The identified transition flows are then compared with observed flows when the flowing stream contracts to the perennial stream head. As evidenced by a correlation coefficient of 0.90, these two characteristics of streamflow are found to be highly correlated, suggesting a fundamental linkage between the transition of base flow recession from early to late stages and the drying up of ephemeral streams. At the early stage, the contraction of ephemeral streams mostly controls the recession behavior. At the late stage, perennial streams dominate the flowing streams and groundwater hydraulics governs the recession behavior. The ephemeral stream densities vary from arid regions to humid regions. Therefore, the characteristics of transition flow across the climate gradients are also tested in 40 watersheds. It is found that climate, which is represented by climate aridity index, is the dominant controlling factor on transition flows from early to late recession stages. Transition flows and long-term average base flows are highly correlated with a correlation coefficient of 0.82. Long-term average base flow and the transition flow of recession are base flow characteristics at two temporal scales, i.e., the long-term scale and the event scale during a recession period. This is a signature of the co-evolution of climate, vegetation, soil, and topography at the watershed scale. The characteristics of early and late recession are applied for quantifying human impacts on streamflow in agricultural watersheds with extensive groundwater pumping for irrigation. A recession model is developed to incorporate the impacts of human activities (such as groundwater pumping) and climate variability (such as evapotranspiration) on base flow recession. Groundwater pumping is estimated based on the change of observed base flow recession in watersheds in the High Plains Aquifer. The estimated groundwater pumping rate is found consistent compared with the observed data of groundwater uses for irrigation. Besides streamflow recession analysis, this dissertation also presents a novel spring recession model for Silver Springs in Florida by incorporating groundwater head, spring pool altitude, and net recharge into the existing Torricelli model. The results show that the effective springshed area has continuously declined since 1988. The net recharge has declined since the 1970s with a significant drop in 2002. Subsequent to 2002, the net recharge increased modestly but not to the levels prior to the 1990s. The decreases in effective springshed area and net recharge caused by changes in hydroclimatic conditions including rainfall and temperature, along with groundwater withdrawals, contribute to the declined spring flow.

Show moreEnd-stage Renal Disease (ESRD) or Chronic Kidney Disease (CKD) constitutes a serious public health problem in the United States. According to the United States Renal Data System (USRDS), in 2013, Medicare spending alone accounts for $30.9 billion for the treatment-related expenses for ESRD. The purpose of this study was to examine the causal relationship of two important determinants, perceived social support and treatment adherence with health-related quality of life (HRQOL) of ESRD patients. Using the health belief model and Bandura's self-efficacy theory, the study explained the theoretical underpinnings of the causal relationships of the patient's perspectives of perceived social support and treatment adherence in predicting the HRQOL of ESRD patients. The study utilized a non-experimental research design and the statistical tool Structural Equation Modeling (SEM), in evaluating the causal relationships between the variables. With a convenience sample size of 413 ESRD patients from the Central West region of Florida, the findings of the study validated a statistically significant relationship between perceived social support and HRQOL as well as between perceived social support and treatment adherence in ESRD patients. However, the study didn't find any significant relationships between treatment adherence and HRQOL. The results of the study enhanced the body of knowledge relating to HRQOL of ESRD patients, provided foundation for interventions and policy formation in improving the HRQOL of patients with ESRD.

Through the analysis of research from leading child psychologists and practical instruction from the Dougy Center, the National Center for grieving children and their families, this research defines important terms and demystifies language surrounding death to aid caregivers in having clear and concise conversations with children about death.The purpose of this document is to counter the American cultural perception of death as a taboo topic for children. Hosting open conversations about death leads to healthier child development, which can help children cope with the loss that everyone will inevitably face in life. Theatre has been proven to work as a catalyst for conversations and create empathy for young audiences. Themes of death can be seen in all forms of storytelling for children , but this study implores the use of theatre to not only reflect experiences of grieving children on stage, but also create preemptive dialogue on the topic, so when tragedy strikes, children can have a tangible example to point back to.The arguments in this document thwart misconceptions of using Piaget's stages of cognitive development and K(&)#252;bler-Ross's five stages of grief as measurements of how all human beings should grieve. Instead of placing grieving children in stages and age groups that exclude important variables, this study focuses on the individual stories that are shared through reflective journals on the investigator's experiences and conversations as a grief facilitator, tutor, and artist in the field of Theatre for Young Audiences. The original play, When Coquis Sing, has been designed to induce conversations on death through the telling of a young protagonist's story of loss, grief, and victory.

Title: When Oppressed Women Attack: Female-Enacted Violence Through Minority American Female Playwrights' Works.
Creator: Busselle, Kate, Boyd, Belinda, Shafer, John, StClaire, Sybil, University of Central Florida
Abstract / Description: As an Actor Combatant with the Society of American Fight Directors, theatrical violence is something that has always captivated me. When a female combat instructor once told me that even though I throw a great punch I will never be able to use it because women are always on the receiving end of violence in theatre, I wondered if this was truly the case. After a thorough exploration of several works with theatrical violence, I am glad to say that it is not the case. When most scholars examine...
Show moreAs an Actor Combatant with the Society of American Fight Directors, theatrical violence is something that has always captivated me. When a female combat instructor once told me that even though I throw a great punch I will never be able to use it because women are always on the receiving end of violence in theatre, I wondered if this was truly the case. After a thorough exploration of several works with theatrical violence, I am glad to say that it is not the case. When most scholars examine violence in theatre, the focus is either male-centric or specifically on domestic violence situations involving a male abusing a female. I will examine theatrical violence through a new lens that has yet to be thoroughly critically explored: violence where the female is the aggressor. Through selected works of three American minority female playwrights: Suzan-Lori Parks' In the Blood, Maria Irene Fornes' Conduct of Life, and Young Jean Lee's Songs of the Dragons Flying to Heaven, I will analyze the female-enacted violence that occurs within these plays using feminist theories and psychology to examine how it happens, why it happens, who the victims are, and what these acts of violence say about minority American women in society today. I will explore the stage directions and dialogue surrounding the violence and analyzing the use or absence of weaponry, the breakdown or build-up of language prior to and after the violent action, and whether or not the violent action occurs before or after a violent action is committed against the female. For comparison, I will also analyze work by an American male playwright with violence in the same way: Tracy Letts' August: Osage County.
