Show moreThis collection of short fiction probes the lives of characters trying to make their home in the flat, unchanging landscape of the small towns that make up central Florida. The largely static environment reflects the rigid patterns of behavior and domesticity the characters find themselves so easily falling into. Seemingly ordinary items--a shotgun, a t-shirt, a paper bag--and the small moments that make up everyday life are imbued with significance as men and women painfully aware of their own ordinariness struggle to hold onto those fragile instances of connection, happiness, or even their own self-constructed sense of identity. The struggle becomes one of opposing forces: as characters yearn to connect to the people, places, and objects around them, they find themselves more and more attracted to the idea of escaping their own lives, even if for just a moment. Stories range from two pages to over twenty and introduce the reader to a diverse population of characters, from an out of work construction worker cum wannabe philosopher to an amateur historian writing a history nobody cares about to the one man who actually did escape--a cockfight organizer who made it big in Georgia before blowing himself up at a gas station. Characters fight over toothbrushes, puzzle out whether a father is just drunk or beautiful, and look for space stations they may or may not be able to see at all. As in life, in these stories, it's the small, quiet moments that come to define who these people are and demonstrate their pursuit of something bigger and more important, even if they don't have any idea what that may be.

Show moreTheoretical perspectives on creativity encompass ideas such as risk, inquiry, resistance to conformity, and attraction to complexity. In response to these philosophical tenets I have organized my dissertation into three distinct but related manuscripts that explore creativity through theoria (knowing), praxis (doing), and poiesis (making). These manuscripts present an integrated approach to creative pedagogy. 1.The first manuscript is a review of literature with the aim to: provide a brief overview of creativity theories; consider an imbricated definition of creativity; and evaluate current empirical research. Research in creativity should provide a spectrum of methods that reflect the complex nature of the phenomenon. 2.Illustrated through the combination of text and authentic photographs, the second manuscript explores how preservice elementary teachers conceptualize their professional identity. This manuscript includes preservice teachers' photographic submissions related to professional identity. Implications include considering how these perceptions affect teacher recruitment, retention, and professional regard within our society and school systems.3.Understanding the interaction between ritual and creativity can elucidate essential qualities of creativity. The third paper will consider the lived experiences of ritual in the creative process of ten Pro-c individuals. As a result of interview analysis, a definition of ritual that is unique to the creative process is revealed. Ritual in the creative process is delineated into three hierarchical categories: (1) Ritual construct, an element of the ritual; (2) Ritual quality, a distinguishing characteristic of the ritual; (3) Ritual purpose, the value the ritual provides in the creative process.

Show moreThe purpose of this research was to investigate the relation between measurement bias at the item level (differential item functioning, dif) and predictive bias at the test score level. Dif was defined as a difference in the probability of getting a test item correct for examinees with the same ability but from different subgroups. Predictive bias was defined as a difference in subgroup regression intercepts and/or slopes in predicting a criterion. Data were simulated by computer. Two hypothetical subgroups (a reference group and a focal group) were used. The predictor was a composite score on a dimensionally complex test with 60 items. Sample size (35, 70, and 105 per group), validity coefficient (.3 or .5), and the mean difference on the predictor (0, .33, .66, and 1 standard deviation, sd) and the criterion (0 and .35 sd) were manipulated. The percentage of items showing dif (0%, 15%, and 30%) and the effect size of dif (small = .3, medium = .6, and large = .9) were also manipulated. Each of the 432 conditions in the 3 x 2 x 4 x 2 x 3 x 3 design was replicated 500 times. For each replication, a predictive bias analysis was conducted, and the detection of predictive bias against each subgroup was the dependent variable. The percentage of dif and the effect size of dif were hypothesized to influence the detection of predictive bias; hypotheses were also advanced about the influence of sample size and mean subgroup differences on the predictor and criterion. Results indicated that dif was not related to the probability of detecting predictive bias against any subgroup. Results were inconsistent with the notion that measurement bias and predictive bias are mutually supportive, i.e., the presence (or absence) of one type of bias is evidence in support of the presence (or absence) of the other type of bias. Sample size and mean differences on the predictor/criterion had direct and indirect effects on the probability of detecting predictive bias against both reference and focal groups. Implications for future research are discussed.

Show moreIn this dissertation, we analyze Kolmogorov's superposition theorem for high dimensions. Our main goal is to explore and demonstrate the feasibility of an accurate implementation of Kolmogorov's theorem. First, based on Lorentz's ideas, we provide a thorough discussion on the proof and its numerical implementation of the theorem in dimension two. We present computational experiments which prove the feasibility of the theorem in applications of low dimensions (namely, dimensions two and three). Next, we present high dimensional extensions with complete and detailed proofs and provide the implementation that aims at applications with high dimensionality. The amalgamation of these ideas is evidenced by applications in image (two dimensional) and video (three dimensional) representations, the content based image retrieval, video retrieval, de-noising and in-painting, and Bayesian prior estimation of high dimensional data from the fields of computer vision and image processing.

Show moreIPV victimization leads many women who suffer from unstable housing into homelessness. These victims are in danger of severe negative health outcomes that are already prevalent in the homeless community, as well as seen in victims of IPV. This study seeks to explore the impact that IPV victimization has on negative health outcomes in the homeless community, compared to the negative health outcomes that homeless women face who are not homeless because of IPV victimization. This study hypothesized that women who are homeless because of IPV victimization face more severe negative health outcomes. The data for the current research is from the Florida Four-City Study of Violence in the Lives of Homeless Women project (Jasinski et. al., 2010) and includes 737 respondents. There was statistically significant findings to support the hypothesis in the health outcomes for the current episode of homelessness for being treated at a clinic for mental problems, self-reported depression, and self-reported anxiety for women who blame their current episode of homelessness on IPV victimization.

Show moreABSTRACT Theatre in its most crude, poignant, and honest form exists as the unapologetic mirror of our world. It houses the piercing reflections of mankind's hope, fear, self-doubt, passion, joy, despair, brilliance, destitution, and desire. It becomes the image of all that man hopes to be, yearns to achieve, and knows he has destroyed. Theatrical performance is without equal in its ability to conjure visible truth from the reflection man sees everyday and hopelessly fails to recognize. Ultimately, theatre demands that man see himself without the masks of excuse, ignorance, or makeup. It is the vision of this journey to honor theatre's mask-less demand. Through the development of a multi-scene theatrical performance; the collection and analysis of relevant research material; and the cultivation of a comprehensive journal outlining the processes, the challenges, and the revelations that will travel the same road--from the cluttered moments of conception to the still air of an empty room after an exhausting final bow--only a mirror will remain. Each component--production, research, and journal--will function as equally essential elements. They will illuminate the evolution of fully realized theatre and detail the composition of a common theatrical message: Truth is both the seed of desperation and discovery.

Diana Pearce's Feminization of Poverty Theory discusses the idea that the ever-rising number of underprivileged Black Americans is due to the fact that there exists a rise in female headed households. The researcher constructed and analyzed several concepts that fall under the Feminization of Poverty Theory: education, employment, family, and social class. For the analysis the study used the documentary Lalee's Kin: The Legacy of Cotton. Results show that each of the categories are approximately equal in proportion under the Feminization of Poverty Theory and that they also affect the impact that capital, government programs, economy, and investments have on underprivileged Black Americans.

Show moreArts-Across-the-Curriculum is gaining popularity in the field of education as arts programs are being cut from schools and teachers look for ways to incorporate art in their classroom. Most of these teachers have minimal formal arts training, but recognize the importance of introducing their students to various fine arts disciplines. These educators seek opportunities to learn new ways to bring arts to their students and may bring teaching artists into their classrooms to teach students or teachers. The clear connection between drama and the core subjects of history and literature allow teaching artists to easily create units utilizing both curriculum areas. Mathematics does not present clear connections to drama and the prevalence of mathematics anxiety, especially in the arts, prevents connections from being made. As an educator, theatre artist and lover of mathematics, Arts-Across-the-Curriculum provides me a opportunity to meld these together as a way to help young people find excitement in their education. Partnering with a fourth grade teacher, I developed a unit of lesson plans using playwriting as a way to understand word problems that was user-friendly for a teacher with no arts training. The Dramath Unit was integrated into the class as part of regular curriculum taught by the participating classroom teacher. Based on feedback from the participating teacher, I revised the unit for future use.

Show moreThis study investigates worldview and ideology during the late Terminal Formative period (A.D. 100 250) in the lower Rio Verde Valley of Oaxaca, Mexico, through an analysis of iconography found on grayware ceramic serving vessels. The sample includes 457 vessels and sherds from 17 lower Verde sites obtained through excavations and surface collections between 1988 and 2009. Drawing upon theories of semiotics and style, this thesis identifies a suite of icons suggesting that ceramics were a medium for expressing regionally shared beliefs. Chatino potters carved common Formative period Mesoamerican themes into the walls of graywares, such as depictions of maize and climatic phenomena, which may have been part of a religious worldview rooted in the belief that humans and non-human deities shared a reciprocal relationship. People at Rio Viejo, including elites, may have attempted to exploit this relationship, thought of as a "sacred covenant" or agreement between humans and deities, to create a more centralized political entity during the late Terminal Formative Chacahua phase. By using iconographic graywares in socially and politically significant ritual activities such as feasting and caching events, elites imbued graywares with a powerful essence that would have facilitated the spread of the coded messages they carried. Based on statistical analyses of the diversity of iconographic assemblages from various sites, I argue that the assemblage of icons at Rio Viejo, a late Terminal Formative political center in the lower Verde, indicates ideas likely originated at or flowed through this site.

Show moreThe time-resolved electrical conductivity of a short-pulse generated plasma filament in air was studied. Close-coupled metal electrodes were used to discharge the stored energy of a high-voltage capacitor and the resulting microsecond-scale electrical discharge was measured using fast current sensors. Significant differences in the time dependence of the current were seen with the two electrode geometries used. Using sharp-tipped electrodes additional peaks in the time-resolved conductivity were seen, relative to the single peak seen with spherical electrodes. We attribute these additional features to secondary electron collisional ionization brought about by field enhancement at the tips. Additional discrepancies in the currents measured leaving the high-voltage electrode and that returning to ground were also observed. Implications for potential laser-induced discharge applications will be discussed.

Show moreThe bandwidth and speed of network connections are continually increasing. The speed increase in network technology is set to soon outpace the speed increase in CMOS technology. This asymmetrical growth is beginning to causing software applications that once worked with then current levels of network traffic to flounder under the new high data rates. Processes that were once executed in software now have to be executed, partially if not wholly in hardware. One such application that could benefit from hardware implementation is high layer routing. By allowing a network device to peer into higher layers of the OSI model, the device can scan for viruses, provide higher quality-of-service (QoS), and efficiently route packets. This thesis proposes an architecture for a device that will utilize hardware-level string matching to distribute incoming requests for a server farm. The proposed architecture is implemented in VHDL, synthesized, and laid out on an Altera FPGA.

Show moreThis study explores the private and public experiences of Black/White interracial lesbian and gay couples. Drawing from the theoretical frameworks of critical race theory and intersectional feminism, this research focuses on how the intersections of gender, race, and sexuality influence relationship experiences and family processes in both private and public spaces for interracial same-sex couples. This study is based on 19 in-depth interviews with individuals in Black/White lesbian and gay relationships. Participants' stories highlight intersectionality in terms of the ways interracial lesbian and gay couples navigate these interpersonal and public spaces. Participant experiences suggest that the dichotomy of private/public is often blurred, and these two spaces frequently overlap and intersect. Often what participants experience in public is then discussed and interpreted within private spaces. It is in the private space that participants work through complex issues in order to present themselves as a couple in public. Participants frequently used their public and interpersonal experiences with their partners to be reflexive of their own understandings of the social world, relationship processes, and love. Given the lack of research on same-sex, interracial families, this study makes an important contribution to sociological research on families, LGTBQ studies, and race studies.

Show moreThe motivation of this research investigation stems from a particular job shop production environment at a large international communications and information technology company in which electro-mechanical assemblies (EMAs) are produced. The production environment of the EMAs includes the continuous arrivals of the EMAs (generally called jobs), with distinct due dates, degrees of importance and routing sequences through the production workstations, to the job shop. Jobs are processed in batches at the workstations, and there are incompatible families of jobs, where jobs from different product families cannot be processed together in the same batch. In addition, there are sequence-dependent setups between batches at the workstations. Most importantly, it is imperative that all product deliveries arrive on time to their customers (internal and external) within their respective delivery time windows. Delivery is allowed outside a time window, but at the expense of a penalty. Completing a job and delivering the job before the start of its respective time window results in a penalty, i.e., inventory holding cost. Delivering a job after its respective time window also results in a penalty, i.e., delay cost or emergency shipping cost. This presents a unique scheduling problem where an earliness-tardiness composite objective is considered.This research approaches this scheduling problem by decomposing this complex job shop scheduling environment into bottleneck and non-bottleneck resources, with the primary focus on effectively scheduling the bottleneck resource. Specifically, the problem of scheduling jobs with unique due dates on a single workstation under the conditions of batching, sequence-dependent setups, incompatible job families in order to minimize weighted earliness and tardiness is formulated as an integer linear program. This scheduling problem, even in its simplest form, is NP-Hard, where no polynomial-time algorithm exists to solve this problem to optimality, especially as the number of jobs increases. As a result, the computational time to arrive at optimal solutions is not of practical use in industrial settings, where production scheduling decisions need to be made quickly. Therefore, this research explores and proposes new heuristic algorithms to solve this unique scheduling problem. The heuristics use order review and release strategies in combination with priority dispatching rules, which is a popular and more commonly-used class of scheduling algorithms in real-world industrial settings. A computational study is conducted to assess the quality of the solutions generated by the proposed heuristics. The computational results show that, in general, the proposed heuristics produce solutions that are competitive to the optimal solutions, yet in a fraction of the time. The results also show that the proposed heuristics are superior in quality to a set of benchmark algorithms within this same class of heuristics.

Show moreA conjugate heat transfer analysis will be carried out to simulate an 89 kN thrust chamber hydrogen cooling channel, to determine the feasibility of adding turbulators to the combustion chamber cooling channels at various parameters such as angle, pitch, and height of the turbulator. An existing regeneratively cooled chamber environment is simulated and used as a baseline case to be compared against. The new design includes using ribbed turbulators or delta wedges in the cooling channels to increase the heat transfer on the channel hot wall (wall adjacent to the hot gas wall) and on the two channel sidewalls. With a higher heat transfer coefficient, the sidewalls behave like fins for heat transfer and participate more in the overall heat transfer process in the channel. Efficient rib and wedge geometries are chosen based on previous investigations. A conjugate heat transfer analysis is performed using a straight duct with the rib and wedge geometries included, with boundary conditions similar to those found in the combustion chamber, to provide thermal hydraulic performance data at numerous turbulator configurations. The baseline channel's maximum hot wall temperature is the target maximum hot wall temperature that is desired to be reduced. The goal is to reduce the hot gas side wall temperature at a minimal cost in pressure drop.

Show morePrevious research has attempted to identify consequences of mental transportation into narrative worlds. While scales have been developed and validated to measure readers' levels of transportation, the objective quantification has left researchers at a descriptive disadvantage for the full range of qualitative responses to this phenomenon. This study presents a qualitative method of inquiry designed to get at the experience of narrative transportation as it is lived: the phenomenological interview. Interview transcripts were inductively analyzed for common themes that indicate intersubjective features of narrative experience. Four main themes were identified, which were composed of 22 base-level experiences reported by participants. These findings corroborated the extant literature and provided a nuanced understanding of the phenomenon as it is lived.

Show moreMarriage and Other Trouble is a collection of (mostly) realist short stories. These stories explore the dynamics of marriage and family, ranging from characters dating in their twenties, to remarrying in their sixties. The characters in this collection grapple with adultery, sexual identity, addiction, class, privilege, and illness. I am interested in the lasting impact of events. Therefore, these stories often reflect on the history of relationships and on how the events of these characters' lives will carry into the future. Mostly set in Florida, place plays an important role in these stories, providing both structure and conflict. The one magical realist story I've included takes place in the afterlife. Addressing suicide and depression, this story explores the guilt over those left behind, and the continual struggle to reconcile with the past, even after death.

Show moreThe purpose of this thesis was to examine the effects of occupational therapy rehabilitation on geriatric patients by reviewing studies conducted on motivation in occupational therapy. In occupational therapy it is important that you set goals for your patients (Creek & Lougher, 2008). It is also important to understand what motivates a patient to achieve those goals because goals and valued activities are intimately connected to motivation. Motivation deals with why we perform certain behaviors. It can predict physical performance and how well a person might recover from an illness and has been suggested to be predictive for rehabilitation success (Carlson, 1997). Because the geriatric population has more longevity, it is important to ensure that they receive the appropriate care necessary to improve and maintain their quality of life (Mason, 1994). After reviewing multiple studies the results reinforced the importance of motivation in occupational therapy treatment. Self-efficacy was found to highly influence a person�s motivation and was a recurring theme throughout this review (Peralta-Catipon & Hwang, 2011). One key to understanding and studying motivation in older adults was to identify what occupations matter to them (Teitelman, Raber, & Watts, 2010). It is important that occupational therapists understand how occupations become meaningful for the geriatric population as participation in those occupations plays an important role in promoting productive aging. When the occupational therapist was able to understand how occupations became meaningful to the patient, they were more equipped to help motivate the patient to participate in their rehabilitation (Janssen & Stube, 2013).

Show moreThe purpose of the study was to ascertain the perception of students in the M.Ed. in Educational Leadership program of mixed reality experiences using TeachLivE(TM) in preparation for the challenges of school leadership. Specifically, the study analyzed the use of mixed reality virtual practice with immediate coaching and feedback in the preparation of educational leadership masters' level students before they engaged in real time communications with parents and teachers. The study encapsulates the perceptions of the master's degree in educational leadership students through the following research questions: (a) To what extent, if any, do Educational Leadership M.Ed. students believe the TeachLivE(TM) parent conference and teacher post observation conference simulation experiences to be helpful in developing their communications skills with parents and teachers? (b) To what extent, if at all, do Educational Leadership M.Ed. students believe the TeachLivE(TM) coaching feedback was helpful in developing their communications skills with parents and teachers? (c) To what extent do student reflections of the TeachLivE(TM) experience indicate it is beneficial in increasing skill in communicating with parents and teachers immediately following the mixed reality simulation? (d) To what extent do Educational Leadership M.Ed. students perceive the TeachLivE(TM) experience to be beneficial in influencing leadership behaviors as they relate to communication with parents and teachers at the end of the second semester administrative internship?Students from the college of education in a large university participated in the study (N = 141). Results show a high-perceived value of the simulation experience and the coaching and feedback in the development of administrative conferencing and communication skills. Descriptive statistics used to answer the research questions show the highest mean for the perceived value of the coaching and feedback, close to (")strongly agree("), from parent conference participants (M = 4.86), followed by teacher conference participants (M = 4.76).Responses for the simulation being beneficial from parent conference participants were also high (M = 4.71), close to (")strongly agree(") and from the teacher conference participants between agree and (")strongly agree(") (4.59). The perceptions of the simulation being realistic practice were between (")agree(") and (")strongly agree(") with parent conference were (M = 4.63) and teacher conferences (M = 4.46).The participant perceptions for the simulation being helpful in building confidence in communication skills was between (")agree(") and (")strongly agree(") for the parent conference (M = 4.41) and close to (")agree(") for the teacher conference (M = 4.14).Participant responses at the conclusion of the internship in practice indicated high value of the mixed reality simulation with mean scores between (")agree(") and (")strongly agree("), in relation to the experience was beneficial to the development of speaking confidence when conferencing with parents (M = 3.57), and the coaching feedback was helpful (M = 3.56). Responses were consistent in rating between (")agree(") and (")strongly agree(") for program continuance immediately following the simulation (M = 4.62), and after the internship (M = 3.67).Recommendations of the study were to ensure that all students have access to the authentic practice model provided by the TeachLivETM mixed reality simulation lab through identified target courses. In addition, it was recommended that more practice opportunities are integrated into the program. These additional experience should include multiple opportunities within the same target courses, as well as investigate additional course work within the Educational Leadership M.Ed. program to integrated the mixed reality simulation to practice specific leadership skills. A final recommendation of this study was to provide opportunities for students to schedule additional practice time in the lab to improve personal professional practice. These recommendations will support the continued development of administrative communication skills of Educational Leadership M.Ed. students, through accurate, realistic and complex situational practice.
