In her 1929 essay "A Room of One's Own," Virginia Woolf famously asserts that "a woman must have money and a room of her own if she is to write fiction" (4). This concept places an immediate importance on the role of the Modernist female subject as an artist and as an architect, constructing the places and spaces that she exists within. With Woolf's argument as its point of departure, this thesis investigates the theme of female space in two Modernist texts: Nella Larsen's Quicksand (1928)...
Show moreIn her 1929 essay "A Room of One's Own," Virginia Woolf famously asserts that "a woman must have money and a room of her own if she is to write fiction" (4). This concept places an immediate importance on the role of the Modernist female subject as an artist and as an architect, constructing the places and spaces that she exists within. With Woolf's argument as its point of departure, this thesis investigates the theme of female space in two Modernist texts: Nella Larsen's Quicksand (1928) and Sylvia Plath's The Bell Jar (1963). The respective protagonists of Quicksand and The Bell Jar, Helga Crane and Esther Greenwood, each undertake journeys to obtain spaces that are purely their own. However, this thesis positions each space that Helga and Esther occupy as both male-constructed and male-dominated in order to address the inherent gendering of space and its impact on the development of feminine identities. This thesis focuses specifically on the roles of the mother, the muse, and the female mentor, tracking the spaces in which Helga and Esther begin to adhere to these roles. Expanding on Lauren Berlant's theory of cruel optimism, this thesis will use the term "cruel femininity" to support its intervening claim that the respective relationships that Helga and Esther each have with their own feminine identities begin to turn cruel as they internalize the male-dominated spatial structures surrounding them. Overall, this thesis argues that there is no space in existence where Helga and Esther can realize their full potential as human beings, as long as the spatial structures within their communities continue to be controlled by hegemonic, patriarchal beliefs.

Show moreStudies of postwar Germany, from 1945-1955, have concentrated on the American influence as a military occupier, the development of German reconstruction and national identity, and memory of this period from the German perspective. Within the memory analyses, firsthand accounts have been analyzed to understand the perspectives of Germans living through the postwar period. Absent from this historiography is an account of American memories and firsthand perspectives of the occupation, particularly during the 1950-1955 period. This thesis employs oral histories of American veterans stationed in postwar Germany, American propaganda and popular cultural mediums during the early 1950s, and modern historiographical trends to provide an understanding of how Americans remember the German postwar decade. American veterans remembered this period, and their encounters with local Germans, as a positive experience. These positive memories were mediated by 1950s Cold War rhetoric and propaganda and were subsequently predicated upon the men's perspective as occupying soldiers. Their recollections align with American popular memory delineating the military occupation as ending in 1949 upon the creation of the Federal Republic of Germany, therefore overshadowing the 1950-1955 period of occupation. The ways in which Americans remember the postwar occupation in Germany, particularly from 1950-1955, inform broader memory and historical narrative trends of this era.

Show moreFood insecurity is not a new phenomenon experienced by elderly persons living in the United States. In a recent report by Feeding America, approximately 4.8 million Americans over the age of 60 are food insecure, which has doubled since 2001, and is 50% higher than in 2007. Due to lack of funding to the program, Meals on Wheels by Seniors First is unable to give meals to seniors in the Central Florida area who are food insecure. Through structured face-to-face interviews, this study examines elders on the program's waiting list and explores how this population obtains food if they are not being served through the program. Findings suggest that seniors on the waiting list are in need of the resource for survival, not convenience. This study has strong implications in which additional funding is needed as the Baby Boomer population ages and the need for food programs increases.

Show moreInstances of traditional school yard bullying among adolescents have been examined by researchers for decades. More recently, cyberbullying has been introduced among adolescents and has begun to be seen as a counterpart to traditional offending behaviors. Scholars have examined the rates of these types of offending, as well as the negative outcomes that result from victimization. However, studies examining the underlying factors that lead to these types of offending, specifically a comparison and combination of the two, are few and far between. This research examines how factors of strain, association with deviant peers, alcohol and/or drug use, and time spent with friends may influence an adolescent's likelihood to engage in any or all offending behaviors. Data are from the Health Behavior in School-Aged Children for which a national sample of 12,642 adolescents aged 10 to 17 years, in grades 5 through 10 were surveyed during the 2009-2010 school year, to assess behaviors that have been linked to health-risks among adolescents. Results indicate that specific factors of strain, drug and/or alcohol use, deviant peers, and time spent with peers significantly impact cyberbullying offending, traditional bullying offending, and both types of offending combined, among adolescents. The findings show that further action should be taken to reduce rates of all types of bullying among adolescents in schools and homes.

Show moreThe purpose of this dissertation in practice was to explore how to bridge the gap between ESOL students and native English speaking students in a collaborative learning environment in a middle school in Tangerine Florida. The gap in performance was highlighted because ESOL students failed to meet the same levels of academic achievement (based on the Florida Standard Assessment Test) as their native English-speaking counter parts. The intent of the dissertation was to design a framework that would meet the pedagogical needs of ESOL students and teachers who teach them. A pilot study was completed that included teachers both ESOL-endorsed and those who were not to determine their needs in terms of professional development that would lead to increased achievement among ESOL students. The study focused on digital schools within one school district. A qualitative research approach was used because it was found to be rigorous, reliable and valid (Morse, Barrett, Mayan, Olson (&) Spiers (2002). Results of the pilot study were intended to inform teachers and school administrators about how to ultimately improve ESOL student performance. The data used in the pilot study were drawn from focus groups as well as information retrieved from reflective teacher and student tools. The conceptual framework that focused the pilot study included socio-cultural theory (Vygotsky, 1986; Mercer, 2007), self-efficacy theory (Bandura, 1997a; Pajares, 1997) culturally responsive teaching theory (Ladson-Billings, 2006; Freire 2000), situated learning theory (Davin (&) Heineke, 2016) and second language acquisition theories (Chomsky, 1965; Ellis, 1997).The findings from the teacher focus groups suggested ways to bridge the gap between the ESOL students and native English speakers. A proposed framework to counter the problem and bridge the gap was designed as a pedagogical intervention (professional development) that would provide the information teachers lack about how to teach ESOL students effectively. The framework also served as a platform to connect and collaborate with other ESOL instructors as a resource and support throughout the school year. Additionally, a teacher-proposed idea was a middle school technology transition (MST2) beginner course for students entering a digital school to give them practice and build their self-efficacy on how to use the necessary applications for each core (FSA tested) class. The results also support the idea that concurrent ongoing professional development and a student introductory technology course throughout the school year could produce more favorable achievement scores of ESOL students, and reduce gaps between ESOL students and native English speaking students.

Show moreThis study examines the phenomena of (tele)presence in the distinct mediated environment of an online Christian worship service. A quantitative field experiment involving 48 participants who had just viewed a religious Internet broadcast was undertaken. Individual differences in personality and religiosity are examined in tandem with (tele)presence as predictors of a number of outcome variables, including memory, enjoyment of the online worship service and behavioral intention to be more active with the church. The results showed no significant relationship between religiosity and the experience of (tele)presence, but that users who experienced greater (tele)presence enjoyed the service more, had a greater ability to recognize information from the service, and had a greater intention to attend in the future. The implications for online worship services, along with the limitations of this study, are discussed.

Show moreThe developing knowledge of life sciences is at the crux of Margaret Atwood's Oryx and Crake as she examines human promise gone awry in a near-future dystopia. This thesis examines aspects of posthumanism, ecocriticism, and feminism in the novel's scientific, cultural, and environmental projections. Through the trope of extinction, Atwood's text foregrounds the effects of human exceptionalism and instrumentalism in relation to the natural world, and engenders an analysis of human identity through its biological and cultural aspects. Extinction thus serves as a metaphor for both human development and human excesses, redefining the idea of human within the context of vulnerable species. Oryx and Crake reveals humanity's organic connections with non-human others through interspecies gene-splicing and the ensuing hybridity. In this perspective, Atwood's text provides a dialogue on humankind's alienation from the natural world and synchronic connections to the animal other, and poses timely questions for twenty-first century consumerism, globalism, and humanist approaches to nature. The loss of balance provoked by the apocalyptic situation in Oryx and Crake challenges commonplace attitudes toward beneficial progress. This imbalance signals the need for a new narrative: A consilient reimagining of humanity's role on earth as an integrated organism rather than an intellectual singularity.

Show moreFor more than fifty years, the Independent (indie) Music Scene has existed as an evolving business model, allowing indie artists to develop a wealth of progressive musical ideas while creating a sustainable audience base. American Musical Theatre has an already-established rich history of adapting styles to fit concurrent trends in popular music while maintaining the story as the core of a show. While some indie artists (The Lisps, The Mountain Goats, Stephin Merritt, and Stew) and some musical theatre composers (David Yazbek, Doug Crossley, and Michael Friedman) have created crossover works, there is currently an overall dearth of musical theatre pieces infused with the indie style and a lack of indie albums with an actable musical theatre storyline. The intent of this thesis is to prove that although American Musical Theatre and the Independent Music Scene are two vastly different art forms, they can be combined to create a viable and unique form that appeals to both audiences. The indie-rock monologue ...and then, Claire was composed, recorded, and performed to test the viability of this thesis. In addition to presenting research on the history of American Musical Theatre and the Independent Music Scene, an analysis of the already-successful artists mentioned above is presented to provide context for ...and then, Claire. This context along with the original indie-rock monologue proves successful combinations of American Musical Theatre and the Independent Music Scene as well as the potential for more attempts in the future.

Show morePolymer-derived ceramics (PDCs) are exceptional ultra-high temperature and stable multifunctional class of materials that can be synthesized from a polymer precursor through thermal decomposition. The presented research focuses on 1-D nanofibers, 2-D films and 3-D bulk, carbon-rich silicon carbon nitride (SiCN) ceramics. 1-D nanofibers were prepared via electrospinning for light weight, flame retardant and conductive applications. The commercially available CerasetTM VL20, a liquid cyclosilazane pre-ceramic precursor, was mixed with polyacrylonitrile (PAN) in order to make the cyclosilazane electrospinnable. Carbon-rich PDC nano?bers were fabricated by electrospinning various ratios of PAN/cyclosilazane solutions followed by pyrolysis. Surface morphology of the electro spun nanofibers characterized by SEM show PDC nano?bers with diameters ranging from 100-300 nm. Also, thermal stability towards oxidation showed a 10% mass loss at 623oC. 2-D carbon/SiCN films were produced by drop-casting a mixture of PAN/cyclosilazane onto a glass slide followed by pyrolysis of the film. Samples ranging from 10:1 to 1:10 PAN:cyclosilazane were made by dissolving the solutes into DMF to produce solutions ranging from 1% to 12% by weight. Green, heat-stabilized, and pyrolyzed 8% films were examined with FTIR to monitor the change in chemical structure at each step of the ceramization. SEM shows that high PAN samples produced films with ceramic embedded spheroid components in a carbon matrix, while high cyclosilazane samples produced carbon embedded spheroid.Finally, this research focuses on the challenge of making fully dense, 3-D bulk PDCs materials. Here we present a composite of SiCN with reduced graphene oxide (rGO) aerogels as a route for fully dense bulk PDCs. Incorporation of the rGO aerogel matrix into the SiCN has its pros and cons. While it lowers the strength of the composite, it allows for fabrication of large bulk samples and an increase in the electrical conductivity of the PDC. The morphology, mechanical, electrical properties and thermal conductivity of graphene-SiCN composite with varying rGO aerogel loading (0.3-2.4%) is presented. The high temperature stability, high electrical conductivity and low thermal conductivity of these composites make them excellent candidates for thermoelectric applications. Generally, carbon-rich SiCN composites with improved thermal and electrical properties are of great importance to the aerospace and electronics industries due to their expected harsh operating environments.

Show moreThis is an exploratory, qualitative study of female musicians and their experiences with discrimination in the music industry. Using semi-structured interviews, I analyze the experiences of nine women, ages 21 to 56, who are working as professional musicians, or who have worked professionally in the past. I ask them how they are treated differently based on their gender. Three forms of subtle discrimination are inferred from their narrative histories. First, female musicians are mistaken for non-musicians. They are encapsulated into inferior roles, like "the gimmick," "good for a girl," and "invisible accessory." Second, band mates and band managers control women's space, success, and artistic freedom. Third, their femininity, sexuality, and age are highly scrutinized. The analysis implies that female musicians are tokenized, devalued, and considered inappropriate for their jobs. Particular attention is paid to the similarities between female musicians and women in male dominated work places. I conclude by discussing the larger implications for gender, music, and social change in a sexist, unregulated industry.

Show moreThulium- and holmium-doped fiber lasers (TDF and HDF) emitting at 2 micron offer unique benefits and applications compared to common ytterbium-doped 1 micron lasers. This dissertation details the concepts, limitations, design, and performance of four 2 micron fiber laser systems. While these lasers were developed for various end-uses, they also provide further insight into two major power scaling limitations. The first limitation is optical nonlinearities: specifically stimulated Brillouin scattering (SBS) and modulation instability (MI). The second limitation is thermal failure due to inefficient pump conversion. First, a 21.5 W single-frequency, single-mode laser with adjustable output from continuous-wave to nanosecond pulses is developed. Measuring the SBS threshold versus pulse duration enables the Brillouin gain coefficient and gain bandwidth to be determined at 2 micron. Second, a 23 W spectrally-broadband, nanosecond pulsed laser is constructed for materials processing applications. The temporally incoherent multi-kW peak power pulses can also efficiently produce MI and supercontinuum generation by adjusting the input spectral linewidth. Third, the measured performance of in-band pumped TDF and HDF lasers are compared with simulations. HDF displays low efficiencies, which is explained by including ion clustering in the simulations. The TDF operates with impressive (>)90% slope efficiencies. Based on this result, a system design for (>)1 kW average power TDF amplifier is described. The designed final amplifier will be in-band pumped to enable high efficiency and low thermal load. The amplifier efficiency, operating bandwidth, thermal load, and nonlinear limits are modeled and analyzed to provide a framework for execution. Overall, this dissertation provides further insight and understanding on the various processes that limit power scaling of 2 micron fiber lasers.

Show moreAn emissions inventory of VOCs, NOx, and CO2 was conducted for three central Florida counties Orange, Seminole, and Osceola (OSO) for calendar year 2008. The inventory utilized three programs: MOBILE6, NONROAD2005, and EDMS (Emissions and Dispersion Modeling System) to model on-road mobile, non-road mobile, and airport emissions, respectively. Remaining point and area source data was estimated from the Florida Department of Environmental Protection (FDEP) and the U.S. Environmental Protection Agency's (U.S. EPA) 2008 emissions inventory. The previous OSO emissions inventory was done in 2002 and in the six years between inventories, there have been changes in population, commerce, and pollution control technology in central Florida which have affected the region's emissions. It is important to model VOC and NOx emissions to determine from where the largest proportions are coming. VOCs and NOx are ozone precursors, and in the presence of heat and sunlight, they react to form ozone (O3). Ozone is regulated by the U.S. Environmental Protection Agency through the FDEP. The current standard is 75 parts per billion (ppb) and Orange County's average is 71 ppb. A new standard (which will likely be about 65 ppb) is being developed and is scheduled to be announced by July 2011. If OSO goes into non-attainment, it will need to prepare a contingency plan for how to reduce emissions to submit to the FDEP for approval. The 2008 inventory determined that approximately 71,300 tons of VOCs and 59,000 tons of NOx were emitted that year. The majority of VOCs came from on-road mobile sources (33%) and area sources (43%), while the majority of NOx came from on-road mobile sources (64%) and non-road mobile sources (17%). Other major sources of VOCs included gasoline powered non-road mobile equipment (lawn and garden equipment), consumer solvents, cooking, and gasoline distribution. With the numbers that could be determined for CO2 emissions, on-road mobile and point sources were responsible for 93%. Of the point source CO2 emissions, almost all of it (87%) came from one large coal-fired power plant in Orange County.

Show moreMalaria afflicts about 500 million people worldwide thus causing significant global economic toll. The drugs available to treat the disease are rapidly losing their efficacy because of widespread prevalence of drug resistant parasites. Thus there is an urgent need to discover novel malaria therapeutics. This research is focused on to study the properties of a novel natural-like synthetic scaffold and analyze its selectivity, and cellular mechanism of action in Plasmodium falciparum. We have identified a novel compound, 3-amino-2-piperidinequinoline (APQ), which we termed UCF401. APQ demonstrated IC50 at submicromolar concentrations against Plasmodium falciparum using the SYBR Green-I fluorescence assay measuring cellular proliferation. This compound also demonstrated low cytotoxicity against the NIH3T3 and HEPG2 cells using MTS assays, showing an IC50 of 174 uM and 125 uM respectively, suggesting of excellent selectivity. We evaluated the compliance of APQ with Lipinski's parameters and determined the in vitro physicochemical profiles of the compound. Our results show that APQ is a Lipinski parameter compliant and has good physicochemical properties. The cellular mechanism of action of APQ was characterized through the assessment of the effects of the compound at different stages of the parasite's intraerythrocytic life cycle. This assay was done by treating a synchronized cell line with the compound at 5X the IC50 value and then imaging the cells at 12-hour intervals. We found that APQ arrests parasite development at the trophozoite stage. In addition we determined that APQ is parasitocidal after a 96 h exposure. These results demonstrate that APQ can be considered as a validated hit and/or early lead.

Radiation therapy has been successful in treating lung cancer patients, but its efficacy is limited by the inability to account for the respiratory motion during treatment planning and radiation dose delivery. Physics-based lung deformation models facilitate the motion computation of both tumor and local lung tissue during radiation therapy. In this dissertation, a novel method is discussed to accurately register 3D lungs across the respiratory phases from 4D-CT datasets, which facilitates...
Show moreRadiation therapy has been successful in treating lung cancer patients, but its efficacy is limited by the inability to account for the respiratory motion during treatment planning and radiation dose delivery. Physics-based lung deformation models facilitate the motion computation of both tumor and local lung tissue during radiation therapy. In this dissertation, a novel method is discussed to accurately register 3D lungs across the respiratory phases from 4D-CT datasets, which facilitates the estimation of the volumetric lung deformation models. This method uses multi-level and multi-resolution optical flow registration coupled with thin plate splines (TPS), to address registration issue of inconsistent intensity across respiratory phases. It achieves higher accuracy as compared to multi-resolution optical flow registration and other commonly used registration methods. Results of validation show that the lung registration is computed with 3 mm Target Registration Error (TRE) and approximately 3 mm Inverse Consistency Error (ICE). This registration method is further implemented in GPU based real time dose delivery simulation to assist radiation therapy planning.

This thesis explores the application of digital technologies in the creation of visionary or transformative artwork. The installation emphasizes number, color, symmetry, and the human form to create symbolic compositions patterned after ancient archetypes. Background research was done to inform the work through studies of the principles of visionary and transformative artwork as practiced by Ernst Fuchs, De Es Schwertberger, and Alex Grey.

Show moreThis thesis explores the application of digital technologies in the creation of visionary or transformative artwork. The installation emphasizes number, color, symmetry, and the human form to create symbolic compositions patterned after ancient archetypes. Background research was done to inform the work through studies of the principles of visionary and transformative artwork as practiced by Ernst Fuchs, De Es Schwertberger, and Alex Grey. Connections between art and spirituality as explained by Kandinsky were studied to augment these principles. The sequence of artwork within the installation is comprised of both digital paintings and interactive triptych panels. To convey a sense of the mystical or sacred, the Rothko Chapel was used to inform the installation and serve as an artistic precedent. As the interactive work is created using realistically-modeled, computer generated characters, special consideration was given to understanding the "uncanny valley" and its potential effect in the interpretation of the installation. Interactivity is achieved through the use of ultrasonic sensors and Arduino prototyping boards.
