Carlos Morton is a prominent Chicano playwright that has contributed greatly to Chicano theatre, creatively and academically, since in 1970s. This thesis offers a feminist analysis of the gender representation in three of his works: Lilith (1977), La Malinche (1984), and Dreaming on a Sunday in the Alameda (1992). The female characters in these three plays possess a unique agency that allows them to challenge oppressive patriarchal standards imposed on their gender identity. The second chapter explores Morton's Lilith, a play based on a Jewish creation myth. In the play, Lilith possesses agency of her gender identity and forms a bond with Eve to fight the patriarchal gender norms used to restrict women in Chicano culture. La Malinche is an adaptation of Eurpides's Medea set in post-Conquest New Spain. Chapter three focuses on the agency displayed by La Malinche through her indigenous roots to fight for her own form of motherhood and freedom from patriarchy. The final play analyzed in this thesis is Dreaming on a Sunday in the Alameda, a dream-like play that is based on Diego Rivera's mural by the same name. Several female characters in the play demonstrate agency through their androgynous sexual identities as they unite …

Because of the non-recurring and transitory nature of discontinued operations, accounting standards require that the results of discontinued operations be separately reported on the income statement. Prior accounting literature supports the view that discontinued operations are non-recurring or transitory in nature, and also suggests that income classified as transitory has minimal relevance in firm valuation. Finance and management literature, however, suggest that firms discontinue operations to strategically utilize their scarce resources. Assuming that discontinued operations are a result of managerial motives to strategically concentrate resources into remaining continued operations, this dissertation examines the informativeness of discontinued operations. In doing so, this dissertation empirically tests the financial performance, investment efficiency, valuation, and analyst forecast accuracy effects of discontinued operations. In 2001, Financial Accounting Standards Board's (FASB) Statement of Financial Accounting Standards (SFAS) 144 (hereafter SFAS 144) replaced Accounting Principles Board's Opinion 30 (hereafter APB 30) and broadened the scope of divestiture transactions to be presented in discontinued operations. Some stakeholders of financial statements argued that discontinued operations were less decision-useful in the SFAS 144 era because too many transactions that do not represent a strategic shift in operations were separately stated as discontinued operations on the income statement. With the possibility …

This thesis serves to highlight the significance of food and diet in the servant problem narrative of eighteenth and nineteenth-century Britain and the role of food in master-servant relationships as a source of conflict. The study also shows how attitudes towards servant labor, wages, and perquisites resulted in food-related theft. Employers customarily provided regular meals, food, drink, or board wages and tea money to their domestic servants in addition to an annual salary, yet food and meals often resulted in contention as evidenced by contemporary criticism and increased calls for legislative wage regulation. Differing expectations of wage components, including food and other perquisites, resulted in ongoing conflict between masters and servants. Existing historical scholarship on the relationship between British domestic servants and their masters or mistresses in context of the servant problem often tends to place focus on themes of gender and sexuality. Considering the role of food as a fundamental necessity in the lives of servants provides a new approach to understanding the servant problem and reveals sources of mistrust and resentment in the master-servant relationship.

Ghana is identified among the developing countries with high maternal mortality ratio in Africa. This study unpacked the Demographic and Health Survey data by examining the maternal health indicators at the district level using GIS methods. Understanding the geographic patterns of antenatal care, place of delivery, and skilled birth attendants at the small scale will help to formulate and plan for location-specific health interventions that can improve maternal health care behavior among Ghanaian women. Districts with high rates and low rates were identified. Place of residence, Gini-Coefficient, wealth status, internet access, and religious affiliation were used to explore the underlying factors associated with the observed patterns. Economic inequality was positively associated with increased use of maternal health care services. The ongoing free maternal health policy serves as a cushion effect for the economic inequality among the districts in the Northern areas. Home delivery is common among the rural districts and is more prominent mostly in the western part of Northern Region and southwest of Upper West. Educating women about the free maternal health policy remains the most viable strategy for positive maternal health outcomes and in reducing MMR in Ghana.

Franz Liszt (1811-1886) made fifty-six transcriptions of Schubert's songs over a period of eight years (1838-46) to introduce the name of the composer, who was little known both in and outside Vienna during his lifetime. Because Liszt intentionally preserved all the details of the original songs, these transcriptions present challenges for a pianist, such as how to produce a vocal line on the piano, as well as interpretive issues such as ornamentation, style, and conveying the meaning of the lyrics on the piano. The purpose of this study is to introduce pianists to study practices employed by singers, with the goal of interpreting the vocal aspects of Liszt's Schubert song transcriptions. The composer Robert Schumann once remarked that Liszt's transcriptions were perhaps the most difficult pieces written for the piano up to that time, and only an intelligent artist could satisfy Liszt's high level of virtuosity without destroying the identity of the original work. This could be considered a warning to pianists not to focus on the technical aspects only. The pedagogical guide presented in the study, based on singers' approaches to the actual songs, should help pianists to "see beyond the notes" and achieve a performance closer to the …

In the field of gifted education, there is little research on the perceptions of high school teachers of the gifted about giftedness, good gifted education practices, and the nature and needs of gifted learners. The purpose of this study was to form a deeper understanding of how those educators who guide gifted learners out of high school and into adulthood perceive giftedness and gifted education. This qualitative study, conducted in two phases, took place in a large suburban school district with three large high school systems and was focused on the responses of high school teachers to assess their attitudes, feelings, and opinions about the nature and needs of gifted learners using a grounded theory model of analysis. Data collected from the 11 participants in the first phase of the analysis was combined with that collected from the 13 participants in phase two and validated throughout with continual comparison through memoing. Participants reported a general lack of engagement with scholarly work in the gifted education field as well as a dependence on the school district for effective training in classroom practice. Evidence also suggested a view of giftedness among the participants as an inherent quality of some people who needed …

Cognitive poetics, the recently developed field of literary theory which utilizes principles from cognitive science and cognitive linguistics to examine literature, is applied in this study to an exploration of the poetry of William Butler Yeats. The theoretical foundation for this approach is embodiment theory, the concept from cognitive linguistics that language is an embodied phenomenon and that meaning and meaning construction are bodily processes grounded in our sensorimotor experiences. A systematic analysis including conceptual metaphors, image schemas, cognitive mappings, mental spaces, and cognitive grammar is applied here to selected poems of Yeats to discover how these models can inform our readings of these poems. Special attention is devoted to Yeats's interest in the mind's eye, his crafting of syntax in stanzaic development, his atemporalization through grammar, and the antinomies which converge in selected symbols from his poems.

An estimated 15 million people in the US have had a near‐death experience (NDE), an experience of usually lucid consciousness during a close brush with death. Following an NDE, experiencers (NDErs) sometimes feel challenged and seek counseling to integrate the experience into their subsequent lives. They have reported psychologically harmful experiences disclosing their NDEs to healthcare professionals, including counselors. Counselors' knowledge and attitude about NDEs appear to be critical variables in their ability to uphold the ethical imperative to do no harm to clients. The recent development of a psychometrically sound instrument to assess these variables, coupled with online availability of a three-part NDE educational program for health professionals, made possible for the first time a large‐scale pre‐post study of the effect of the program on counselors' knowledge and attitude about NDEs. Participants were 212 licensed professional counselors (LPCs) aged 23 to 71 years old (M = 44.93, SD = 12.69); sex self-identified as 12.3% male, 87.3% female, and .5% other; racially/ethnically self-identified as 84% White and 17% non-White and as 6.6% Latino-Hispanic and 92.5% non-Latino/Hispanic; and representing four regions of the US. Results revealed that, compared to control group, composed of LPCs who completed topically unrelated online programs (n …

Mutations of three genes encoding amyloid precursor protein (APP), presenilin-1 (PSEN1), and presenilin-2 (PSEN2) have been shown to reliably result in familial early-onset Alzheimer's disease (FAD); a rare, but catastrophic, subtype of Alzheimer's disease (AD) marked by symptom emergence before age 65 as well as accelerated cognitive deterioration. The current study represents the first known meta-analysis on the association of APP, PSEN1 or PSEN2 on neurocognitive variables. A total of 278 FAD mutation-carriers (FAD-MC) and 284 cognitively healthy non-mutation-carriers (NC) across 10 independent investigations meeting inclusion criteria were chosen for the current meta-analysis (random effects design). Findings revealed an overarching trend of poorer performance by FAD-MC individuals compared to NC individuals across the majority of cognitive domains identified. Significant differences in effect sizes suggested FAD-MC individuals exhibited worse performance on measures of attention, explicit memory, fluency, primary memory, verbal, and visuospatial functioning. Findings indicative of differential sensitivity to cognitive domain impairments across FAD-MC and NC groups inform neuropsychological descriptions of individuals in preclinical phases of FAD.

The problem this study addressed is the relationship between Clery Act crime data and student recruitment at private colleges and universities. For this quantitative study, I used secondary data from the Department of Education and the Delta Cost Project (2013) to conduct ordinary least squares regression analyses to determine the predictive ability of institutional characteristics, specifically the total number of crime incidents reported in compliance with the Clery Act, on the variance in number of applications and applicant yield rate at private four-year institutions in the United States. Findings showed that the total number of reported incidents was a significant positive predictor of the total number of applications. Conversely, findings also showed that the total number of incidents had a significant negative impact on institutional yield rates. An implication of this study is that although crime statistics required by the Clery Act may not serve as variables used in the student application process, they are part of numerous variables used in the student's decision to enroll at a particular school. The findings highlight the importance of prioritizing and investing in safety and security measures designed to reduce rates of crime; especially for private, enrollment-driven institutions of higher education.

According to the U.S. Department of Education, in 2015, Texas special education programs were rated among the lowest in the nation. School districts in the state have a substantial need for effective and efficient staff training. In this study, researchers implemented TAPS: A Talk Aloud Problem Solving Approach Packet to teach active listener qualities to staff members in a life skills special education classroom. A multiple baseline across staff members was used to evaluate the effects of the TAPS training on the presence and absence of the staff members' active listener qualities during a pre-test, a post-test, and probes. The staff members that underwent TAPS training acquired all of the active listener qualities as a function of the TAPS training, and the effects of the training maintained during probe sessions. Additionally, TAPS training appeared to improve staff members' scores on the Whimbey Analytical Skills Inventory (WASI) Test and anecdotally improved the quality of staff and student tutoring interactions. Several areas of potential research and improvement are discussed.

In game based learning, motivating the players to learn by providing them a desirable gameplay experience is extremely important. However, it's not an easy task considering the quality of today's commercial non-educational games. Throughout the gameplay, the player should neither get overwhelmed nor under-challenged. The best way to do so is to monitor the player's actions in the game because these actions can tell the reason behind the player's performance. They can also tell about the player's lacking competencies or knowledge. Based on this information, in-game educational interventions in the form of hints can be provided to the player. The success of such games depends on their interactivity, motivational outlook and thus player retention. UNTANGLED is an online mapping game based on crowd-sourcing, developed by Reconfigurable Computing Lab, UNT for the mapping problem of CGRAs. It is also an educational game for teaching the concepts of reconfigurable computing. This thesis performs qualitative comparative analysis on gameplays of low performing players of UNTANGLED. And the implications of this analysis are used to provide recommendations for improving the gameplay experience for these players by guiding them. The recommendations include strategies to reach a high score and a compact solution, hints in the …

My thesis research provides an alternative argument for the protection of the wilderness that extends far beyond that of the purely biological and instead looks at wilderness for the intrinsic value, focusing on the social and cultural aspects. Through an ethnographic approach, I uncovered the how, why, and in what context people connect with wilderness and how people lean on these experiences. Through analysis of the interviews and data that was collected, I was able to identify tangible and intangible values associated with wilderness exploration and understand how these social and cultural aspects manifest themselves in people's day-to-day lives.

Using a modified still-face procedure the present study explores 3-6-month-old infants' behavioral and physiological responses to mothers' screen distractions during mother-infant interactions. In the modified phone still-face procedure the neutral face of the traditional still face procedure was replaced with mothers' texting on their mobile phones. Infants' cortisol stress responses to mothers' device use were assessed through the collection of 3 infant saliva samples. Infants' behavioral responses including facial expressions, vocalizations, gaze and self-comforting behaviors were also explored. All mother-infant interactions were videoed recorded and coded for analysis. Thirty-four mother-infant dyads participated, average ages for mothers was 29 years and 4.4 months for infants. As predicted, infants demonstrated the changes in affect associated with the still-face effect, with significant differences in positive and negative affect during the play phases and the phone still face phase. As a whole, infants did not respond with increased cortisol responses, however, when individual differences were explored 47% responded with increased stress during mothers' phone distractions. Mother's frequency and attitudes towards device use were also assessed but were unrelated to infant responses. Implications and directions for future research are discussed.

Wearable technology has made a positive impact in the consumer industry with its focus on adult fitness. Devices and applications are pervasive, inexpensive and are in high demand. Our nation struggles with obesity and health concerns related to poor fitness. However, the research on such technology has been more focused on adults. Therefore, the need to investigate wearable technology for fitness improvement with children is essential. Children lead increasingly sedentary lifestyles through TV watching, technology-use and a reduction in physical activities. Further, our society is exposed to quick food loaded with calories. These factors contribute to the growing epidemic of childhood obesity. The need to educate students early, on their ability to monitor their fitness, is the focus of this research. This dissertation investigated the impact of an integrated technology-enhanced physical education model with 127 fifth grade students over an 11-week period. A detailed analysis, looking at theoretical perspectives across multiple data collections was conducted. This study answered the questions, 1. To what extent can students improve their performance with technology-enhanced physical education? 2. To what extent can students learn to self-monitor their performance levels? How do affective components impact teaching and learning with a technology-enhanced physical education model? Results …

This work investigated a novel vapor chamber for efficient heat spreading and heat removal. A vapor chamber acting as a heat spreader enables for more uniform temperature distribution along the surface of the device being cooled. First, a vapor chamber was studied and compared with the traditional copper heat spreader. The thickness of vapor chamber was kept 1.35 mm which was considered to be ultra-thin vapor chamber. Then, a new geometrical model having graphite foam in vapor space was proposed where the graphite foam material was incorporated in vapor space as square cubes. The effects of incorporating graphite foam in vapor space were compared to the vapor chamber without the embedded graphite foam to investigate the heat transfer performance improvements of vapor chamber by the high thermal conductivity graphite foam. Finally, the effects of various vapor chamber thicknesses were studied through numerical simulations. It was found that thinner vapor chamber (1.35 mm thickness) had better heat transfer performance than thicker vapor chamber (5 mm thickness) because of the extreme high effective thermal conductivities of ultra-thin vapor chamber. Furthermore, the effect of graphite foam on thermal performance improvement was very minor for ultra-thin vapor chamber, but significant for thick vapor chamber. …

This study aims to investigate variable flow and intermittent flow spray cooling characteristics for efficiency improvement in active two-phase thermal management systems. Variable flow spray cooling scheme requires control of pump input voltage (or speed), while intermittent flow spray cooling scheme requires control of solenoid valve duty cycle and frequency. Several testing scenarios representing dynamic heat load conditions are implemented to characterize the overall performance of variable flow and intermittent flow spray cooling cases in comparison with the reference, steady flow spray cooling case with constant flowrate, continuous spray cooling. Tests are conducted on a small-scale, closed loop spray cooling system featuring a pressure atomized spray nozzle. HFE-7100 dielectric liquid is selected as the working fluid. Two types of test samples are prepared on 10 mm x 10 mm x 2 mm copper substrates with matching size thick film resistors attached onto the opposite side, to generate heat and simulate high heat flux electronic devices. The test samples include: (i) plain, smooth surface, and (ii) microporous surface featuring 100 μm thick copper-based coating prepared by dual stage electroplating technique. Experimental conditions involve HFE-7100 at atmospheric pressure and 30°C and ~10°C subcooling. Steady flow spray cooling tests are conducted at flow …

Energy efficiency in the operation of buildings is becoming increasingly important with a growing emphasis on sustainability and reducing environmental impacts of irresponsible energy usage. Improvements have been made both on the technology side of energy efficiency and on the human behavior side. However, when changing human behavior, it is critical to find energy conservation measures that will maintain comfort for occupants. This paper analyzes how this can be done by implementing a modulating temperature schedule based on the concept of alliesthesia, which states that pleasure is observed in transient states. EnergyPlus simulations were used to show that in cooling applications, this type of scheduling can produce significant energy savings. However, energy savings are not predicted for the same type of scheduling for heating applications. Thermal comfort was examined with a cooling experiment and a separate heating experiment, each lasting 45 minutes and taking place during the corresponding season. The experiments showed that modulating temperatures can cause occupants to experience more pleasure than if the temperature remained constant in a cooled space, whereas modulating temperatures had a negative impact on comfort relative to the constant temperature in the heated space. This presents evidence for an ideal opportunity for cooling applications …

Wireless sensor networks are an indispensable tool in this highly connected world. WSNs have been the focus of research efforts in areas of communication, electronics and control for many years. Advancements in the fields of MEMS, RF and digital circuit technology has led to the development of low cost and extremely power efficient smart sensors. This has led to the need of a fast, reliable and inexpensive method of consensus building for these sensor networks. Basic concepts of graph theory and consensus building are explained in this thesis. This thesis reviews the models and strategies for consensus building present in the literature. The shortcomings of these models are explained through examples and a leader-follower model based consensus building strategy is presented. Algorithm to convert any graph into a bipartite graph by edge removal and a strategy to select effective leaders based on a weighted combination of node centrality, ratio of leaders to the total number of nodes and presence of leaf nodes in the group is presented in this thesis. Proposed leader-follower model is compared against classic models for consensus building are compared and proven to be better. Mobility is studied using deterministic and random mobility models to show the …

Developmental education courses are typically defined as courses offered at postsecondary institutions below college level instruction. More than 60% of community college students are deemed non-college ready and required to enroll in non-credit bearing developmental education courses. Research shows that developmental education can be either a bridge or barrier to degree attainment for racial/ethnic minority students, particularly African Americans, who require developmental education more than any other racial/ethnic groups. The purpose of this study was to explore the lived experiences of African American community college achievers who were required to enroll in two or more developmental education courses. Achievers were defined as students who passed all developmental education courses and were enrolled in their final college gateway course at the time of the interviews. Utilizing a phenomenological approach and anti-deficit framework, 15 semi-structured interviews were conducted to capture the essence of how African American achievers described, interpreted, and understood their journeys from developmental education to becoming college ready to completing college level courses. Twelve participants were female and three were male, ranging from 20 to 52 years old. Results revealed seven major themes. The first research question addressed how achievers described their developmental education experience from pre-collegiate years through inside …

Mechanical properties of structural materials are highly correlated to their microstructure. The relationship between microstructure and mechanical properties can be established experimentally. The growing need for structural materials in industry promotes the study of microstructural evolution of materials by design using computational approaches. This thesis presents the microstructural evolution of two different structural materials. The first uses a genetic algorithm approach to study the microstructural evolution of a high-temperature nickel-based oxide-dispersion-strengthened (ODS) alloy. The chosen Ni-20Cr ODS system has nano Y2O3 particles for dispersion strengthening and submicron Al2O3 for composite strengthening. Synergistic effects through the interaction of small dispersoids and large reinforcements improved high-temperature strength. Optimization considered different weight factors on low temperature strength, ductility, and high temperature strength. Simulation revealed optimal size and volume fraction of dispersoids and reinforced particles. Ni-20Cr-based alloys were developed via mechanical alloying for computational optimization and validation. The Ni-20Cr-1.2Y2O3-5Al2O3 alloy exhibited significant reduction in the minimum creep rate (on the order of 10-9 s-1) at 800oC and 100 MPa. The second considers the microstructural evolution of AA 7050 alloy during friction stir welding (FSW). Modeling the FSW process includes thermal, material flow, microstructural and strength modeling. Three-dimensional material flow and heat transfer model was …

Nearly 700,000 suspects with mental disorders are arrested and Mirandized each year. The current study systematically examined the effects of cognitive deficits and psychological symptoms on both Miranda comprehension and reasoning. The current sample was comprised of 85 adult psychiatric inpatients recruited from University Behavioral Health (UBH), a private psychiatric hospital in North Texas. Unexpectedly, most inpatients demonstrated pervasive deficits in their immediate recall of a representative Miranda warning, omitting approximately four-fifths of its content. In addition, the majority of inpatients evidenced damaging errors in their reasoning about waiver decisions. As a result, 64.7% waived and subsequently confessed after only a 3-5 minute interrogation. Interestingly, impaired verbal ability but not the severity of their symptoms predicted greater deficits in Miranda comprehension.

In my dissertation, I explore the ways in which racial identity is made complex through various onlookers' misrecognition of race. This issue is particularly important considering the current state of race relations in the United States, as my project offers a literary perspective and account of the way black authors have discussed racial identity formation from the turn of the century through the start of the twenty-first century. I highlight many variations of misrecognition and racial performance as a response to America's obsession with race.
