A collection of poems that explores notions of disability, family, and belief, with a preface that meditates on questions related to the ethical ramifications of various approaches to the making of poetry and art that takes up the suffering of others as subject matter.

Many factors have prompted the adoption of partial-market exit strategies in retail as a means of reducing cost and minimizing risk. These mass closures have become more frequent in recent years. Marketers and economists have offered explanations for these closures linked to the rise of e-commerce, the real estate cycle and general changes in consumer taste. The research here marks an attempt to apply geospatial and econometric methods to better understand what factors explain the spatial variation of these closures across the United States. Specifically, the analysis examines the store networks of Sears, J.C. Penney and Macy's- large, established department stores that, collectively, announced over 100 closures at the beginning of 2017. By treating each store as a unit of observation, and a closure as a limited dependent variable, this analysis will attempt to quantify the relationship between place-specific factors and retail closures using Probit modeling. This application of modeling marks a deviation from traditional analyses in retail geography which, up until the early 2000s, have focused almost entirely on store development and growth. The results reveal patterns of spatial clustering of closures in and around the Rust Belt and demonstrate the strong negative effect of competitive agglomeration on the …

Union is a novel about a Super AI that takes over all human technology.

Using ethnographic research methods, I worked with the International Game Developers Association (IGDA) to conduct an exploratory study about developer perspectives on video game preservation. I conducted in-depth interviews with independent developers in the Dallas-Fort Worth region, a hub for Texas game development. These interviews explored developers' knowledge and awareness of game preservation as a topic of concern, archival culture and practices in the industry, and the IGDA's potential role in addressing issues related to preservation work. This research contributes to a growing body of literature on game preservation, urgently needed as many gaming technologies face obsolescence in the near future. I use Ellen Cushman's concept of "perseverance" to examine the difference between simply preserving video games for the future, and the perseverance of game development as a professional trade and artistic craft.

Many clients with developmental and/or intellectual disabilities (ID/DD) do not tolerate routine medical or dental procedures and may require intrusive interventions, including restraint of various types (i.e. chemical, mechanical, physical, etc.) during appointments. Graduated exposure, or stimulus fading, along with reinforcement for compliance, have been shown to increase cooperation and tolerance in some clients; however, many do not respond to these types of interventions. Nine participants diagnosed with ID/DD recieved compliance/tolerance training for routine medical or dental procedures. Results of these interventions were evaluated in the context of several potential indices of readiness, such as medical diagnoses, level of disability, and presence of challenging behavior, among others. Several of the variables appeared to be correlated with program responsiveness; however, a larger sample will be necessary to draw definitive conclusions. Client characteristics and past assessments (anecdotals, preference assessments, terminal probes, and survey data) were evaluated. The analytical framework developed for this analysis may be useful to future researchers and clinicians as a model for assessing readiness for tolerance training programs.

The rationale of color-blind ideology in the socializing space of the early childhood classroom encourages that racial, cultural, and ethnic differences remain unrecognized. Demographic shifts of diverse marginalized populations within majority, White suburban schools require the analysis of dominant ideologies that potentially leave biases unchallenged. This photovoice project centered the voice of three Black, early childhood educators working within majority White suburban schools in the South to explore how they rationalized the discourse of color-blind ideology in their professional and personal lives. Findings showed that Black women's critical social location within a racialized society and their historical engagement with Black oppositional knowledge structured oppositional knowledges and embodied critiques of suburban spaces. They crafted wisdoms for engaging and navigating tensions with colleagues, parents, and administrators and nurtured embodied perspectives, resisting stereotypical images of Black women and girls. Deconstructed dominant ideologies in the socializing space of the early childhood classroom extend and modify our understanding of racialized knowledge in our educational spaces and offer transformative readings of color-blind ideology.

This project seeks to clarify the historical significance of women in the American West between 1870 and 1930 through the education, careers, and personal lives of western women physicians. The narratives presented in the work provide alternative roles for western women aside from the stereotypical images found in popular culture and history, such as the "Bad Woman," the prostitute, and the obedient homesteading wife. This collective biography additionally demonstrates how women participated in American medical culture during the nineteenth and early twentieth centuries, emphasizing their agency as historical actors, and countering the common misconception that Victorian women were merely passive subjects of their time and place. The lives of four physicians named Ellis Reynolds Shipp, Mary Babcock Atwater, Mary Bennett Ritter, and Mary Canaga Rowland are available through memoirs, biographies, scholarly articles, newspapers, and other sources that contextualize their careers into the broader context of Western, medical, and nineteenth-century history. Through their personal and professional experiences, a greater story of female autonomy emerges in a period understood to be inherently oppressive to and unnavigable for women.

Bacteriophages are viruses that specifically infect bacteria. When a phage infects a bacterium, it attaches itself to the surface of the bacteria and injects its DNA into the intracellular space. The phage DNA hijacks the cellular machinery of the bacteria and forces it to produce phage proteins. Eventually, the bacteria cell bursts or lyses, releasing new phage. The bacteria act as a host for phage reproduction. The ability for a phage to infect multiple bacterial species is known as host range. In siphoviridae bacteriophages, host range is thought to primarily be determined by proteins at the tip of their tail fibers. These proteins act as anti-receptors to specific receptors on the surface of bacteria. In siphoviridae Gram-positive infecting phages, the genes that code these proteins are typically located between the tape measure protein gene and the endolysin gene. It is hypothesized that phages that have similar anti-receptor proteins will have similar host range. In this study, the host ranges of 12 BD1 bacteriophages were tested on 9 different Streptomyces species. In these 12 phages, the genes between the tape measure protein gene and endolysin gene were compared. The 12 phages had high levels of variability in these genes. Five genes …

This thesis describes the fabrication and characterization of two-dimensional transition dichalcogenides (2D TMDs) nanolayers for various applications in electronic and opto-electronic devices applications. In Chapter 1, crystal and optical structure of TMDs materials are introduced. Many TMDs materials reveal three structure polytypes (1T, 2H, and 3R). The important electronic properties are determined by the crystal structure of TMDs; thus, the information of crystal structure is explained. In addition, the detailed information of photon vibration and optical band gap structure from single-layer to bulk TMDs materials are introduced in this chapter. In Chapter 2, detailed information of physical properties and synthesis techniques for molybdenum disulfide (MoS2), tungsten disulfide (WS2), and molybdenum ditelluride (MoTe2) nanolayers are explained. The three representative crystal structures are trigonal prismatic (hexagonal, H), octahedral (tetragonal, T), and distorted structure (Tʹ). At room temperature, the stable structure of MoS2 and WS2 is semiconducting 2H phase, and MoTe2 can reveal both 2H (semiconducting phase) and 1Tʹ (semi-metallic phase) phases determined by the existence of strains. In addition, the pros and cons of the synthesis techniques for nanolayers are discussed. In Chapter 3, the topic of synthesized large-scale MoS2, WS2, and MoTe2 films is considered. For MoS2 and WS2 films, the …

With the advent of information explosion age, larger capacity disk drives are used to store data and powerful devices are used to process big data. As the scale and complexity of computer systems increase, we expect these systems to provide dependable and energy-efficient services and computation. Although hard drives are reliable in general, they are the most commonly replaced hardware components. Disk failures cause data corruption and even data loss, which can significantly affect system performance and financial losses. In this dissertation research, I analyze different manifestations of disk failures in production data centers and explore data mining techniques combined with statistical analysis methods to discover categories of disk failures and their distinctive properties. I use similarity measures to quantify the degradation process of each failure type and derive the degradation signature. The derived degradation signatures are further leveraged to forecast when future disk failures may happen. Meanwhile, this dissertation also studies energy efficiency of high performance computers. Specifically, I characterize the power and energy consumption of Haswell processors which are used in multiple supercomputers, and analyze the power and energy consumption of Legion, a data-centric programming model and runtime system, and Legion applications. We find that power and energy …

Undergraduate nursing students face tremendous stress in regards to academic and clinical demands while emotional intelligence (EI) is a topic of interest in the nursing field. This study examined whether problem-focused coping methods for stress are related to ability and personality. In this study, EI represented ability and locus of control (LOC) represented personality. Confrontive coping, seeking social support, and planful problem-solving represented the problem-focused coping variables. A survey instrument which represented a combination of the Assessing Emotions Scale, Perceived Stress Scale, Ways of Coping Scale (Revised), and the Rotter Locus of Control Scale was administered to 11 undergraduate nursing schools during the spring semester of 2019. The results indicated that EI had strong and statistically significant correlations with each of the other variables in the study which were LOC, stress, confrontive coping, seeking social support, and planful problem-solving. The results further supported that EI was a statistically significant predictor for each of the three problem-focused coping variables. It was concluded that level of stress did not mediate the relationship between EI and any of the three problem-focused coping methods. In addition, LOC moderated the relationship between EI and stress. The limitations and possibilities for future research are addressed in …

Negation is a complex phenomenon present in all human languages, allowing for the uniquely human capacities of denial, contradiction, misrepresentation, lying, and irony. It is in the first place a phenomenon of semantical opposition. Sentences containing negation are generally (a) less informative than affirmative ones, (b) morphosyntactically more marked—all languages have negative markers while only a few have affirmative markers, and (c) psychologically more complex and harder to process. Negation often conveys positive meaning. This meaning ranges from implicatures to entailments. In this dissertation, I develop a system to reveal the underlying positive interpretation of negation. I first identify which words are intended to be negated (i.e, the focus of negation) and second, I rewrite those tokens to generate an actual positive interpretation. I identify the focus of negation by scoring probable foci along a continuous scale. One of the obstacles to exploring foci scoring is that no public datasets exist for this task. Thus, to study this problem I create new corpora. The corpora contain verbal, nominal and adjectival negations and their potential positive interpretations along with their scores ranging from 1 to 5. Then, I use supervised learning models for scoring the focus of negation. In order to …

The thesis simulates the problem of network connectivity that occurs due to the dynamic nature of a network during flight. Nine nodes are provided with initial positions and are flown based on the path provided by leader-follower control algorithm using the server-client model. The application layer provides a point to point connection between the server and client and by using socket programming in the transport layer, a server and clients are established. Each node performs a neighbor discovery to discover its neighbors in the data link layer and physical layer performs the CSMA/CA using RTS/CTS. Finally, multi hop routing is achieved in network layer. Each client connects with server at dedicated interval to share each other location and then moves to next location. This process is continued over a period of several iterations until the relative distance is achieved. The constraints and limitations of the technology are network connectivity is lack of flexibility for random location of nodes, links established with a distant node having single neighbor is unstable. Performance of a system decreases with increase in number of nodes.

Emma Diruf Seiler (1821-1886) was a Bavarian-American voice teacher and scientist who wrote and published Altes und Neues über die Ausbildung des Gesangorganes mit besonderer Rücksicht auf die Frauenstimme (Old and New in the Art of Singing, with Special Attention to the Female Voice) in 1861 while working in Leipzig. It was translated by William Henry Furness and published in Philadelphia as The Voice in Singing in 1868. This pedagogue and her writings are largely unknown to those who study historic bel canto pedagogy. In the opening of Seiler's pamphlet, she explained her purpose for writing was "to bring into harmony things which have always been treated separately, the Science and the Art of Singing..." Aside from brief comments in a few books on vocal pedagogy, Emma Seiler is largely unknown. Neither her contribution to voice science and pedagogy, nor the impact of her integrated philosophy on teaching have been subjected to scholarly scrutiny. The purpose of this document is to explore her philosophy on teaching, her method of female vocal instruction, and her impact on voice instruction. This dissertation historicizes evidence-based pedagogy through Seiler's example.

Beyond the Binary explores the intersection of gender with cross-cultural identity in composer Reena Esmail's professional life and choral music. This intersection manifests in her musical style, which accesses the resonant spaces between Western and Indian classical music. I argue that it is through the convergence of Esmail's gender identity with her cross-cultural identity that her compositions challenge gender norms and break down perceived barriers between East and West, inviting her listeners into an intersectional feminist space. This project synthesizes musicological, theoretical, and ethnographic methods, and is meant as a starting point for choral musicians and scholars to consider cultural difference and its impact on choral music. What begins as a consideration of social themes within Esmail's life and work culminates in a practical musical analysis and performance practice guide to aid conductors in preparation of Esmail's music. The compositions discussed are I Rise: Women in Song (2016), Take What You Need (2016), TaReKiTa (2016), Tuttarana (2014), and This Love Between Us: Prayers for Unity (2016).

This collection of 9 vocal works, taken from the oœuvre of André-Ernest-Modeste Grétry (1741-1813), was chosen for their utility in teaching undergrad voice majors. This collection offers a group of songs that are attractive in their simplicity allowing the time in their lessons to be devoted to the instruction of French pronunciation. Grétry's attention to detail in the setting of French prosody provides undergraduate singers with a collection of songs that offer an immediate understanding as to the nuances of the French language. With funding from an I-GRO grant through the University of North Texas, research was conducted in the archives of the Bibliothèque nationale de France, and work continued in the Grétry Museum in Liège, Belgium. The primary sources found within these locations formulated valuable insights into to the life and influence of Grétry, and provided first-hand experience with research techniques within foreign libraries. This research has solidified the relationship between Grétry's compositional style and its usefulness within the undergraduate voice studio.

First, we show that the Rothberger and 2-Rothberger games are equivalent. Then we adjust the former proof and introduce another game, the restricted Menger game, in order to obtain a broader result. This provides an answer in the context of Hausdorff spaces for an open question posed by Aurichi, Bella, and Dias.

Quiet Flows the River explores the lives of the people living in the coastal area of Bangladesh. Affected by the consequences of climate change, they continue to adapt and struggle each day to survive in their homelands.

Urban land use and land cover has changed in the USA, giving rise to the American lawn – manicured, resource-intensive, and non-native. Green infrastructure design has been suggested in the literature as a potential alternative to the American lawn when managed as native xeriscapes, which require little to no irrigation after establishment. Given the influence of public preference on landscaping decisions, what is the relationship between the perceived value and ecological benefits of the American lawn compared to such alternatives? Few studies have explored this question in addition to the effects of college courses on influencing student preferences, as future stakeholders, towards native xeriscapes as alternatives to the American lawn. This research measured the effects of an introductory environmental education (EE) course on measurably influencing undergraduate student preferences for four xeriscapes as alternatives to the American lawn. To measure these effects, this study utilized the perceptions of 488 students enrolled in an indirect introductory EE course and 131 students enrolled in an introductory non-EE course. Three key results emerged from this research. Students preferred the American lawn more than xeriscape alternatives, irrespective to course enrolled. Introductory non-EE did not have an effect on student preferences, whereas indirect introductory EE did …

Recent progress in layered transition metal dichalcogenides (TMDs) has led to various promising electronic and optoelectronic applications. However, the structure of materials plays a critical role in electronic and optoelectronic devices, and determines performance. Electronic and optoelectronic devices typically consist of multiple layers that form electrical homojunctions or heterojunctions. Therefore, in a device it can be expected that a WS2 layer may serve as the substrate for a subsequent layer in a multilayer device stack and determine how the layer grows. In transistor structures, roughness at the channel/gate dielectric interface introduces field variations and charge scattering. Therefore, understanding the relations between processing, surface morphology and properties is important. In this project, the effects of pulsed laser deposition (PLD) processing conditions on the surface morphology of few layered WS2 films were studied. WS2 films were synthesized under processing conditions that represent the extremes of surface supersaturation and kinetic energy transfer from the flux to the growing films, and evolution of the surface morphology was studied. The specific conditions were 1Hz/50mJ, 10Hz/50mJ, 1Hz/300mJ, and 10Hz/300mJ respectively. Combining AFM, XRD and Raman analyses, it was determined that deposition at 10Hz/300mJ, provided the best structural properties and surface morphology. Growth appeared to be 3D-cluster, …

Between 1947 and 1954, the Texas State Legislature enacted a series of eight highly restrictive anti-communist laws. Designed to protect political, military, and economic structures in the state from communist infiltration, the laws banned communists from participating the political process, required registration of all communists who entered the state and eventually outlawed the Communist Party. Drawn from perceptions about Cold War events, such as the Truman Doctrine and the Korean War, and an expanding economy inside of Texas, members of the state legislature perceived that communism represented a threat to their state. However, when presented with the opportunity to put the laws into action during the 1953 Port Arthur Labor Strike, the state government failed to bring any charges against those who they labeled as communists. Instead of actually curtailing the limited communist presence inside of the state, members of the state government instead used the laws to leverage political control throughout the state by attacking labor, liberals in education and government, and racial minorities with accusations of communism.

Brazos is a collection of poetry that comments on and critiques life in a small town in Texas. These poems situate the speaker both in this town and in spaces removed from the town, but the work always grapples with questions of how the speaker identifies himself via the relationship to that space. The creative portion is accompanied by a critical introduction that looks at the intersections of poetry and the lyric essay.

In this study, a series of denim fiberboards are fabricated using two different resins, malamine urea formaldehyde (MUF) and polymeric methylene diphenyl diisocyanate (pMDI). Two experimental design factors (1) adhesive content and (2) MUF-pMDI weight ratio, were studied. All the denim fiberboard samples were fabricated following the same resin blending, cold-press and hot-press procedures. The physical and mechanical tests were conducted on the fiberboard following the procedures described in ASTM D1037 to obtain such as modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB), thickness swell (TS), and water absorption (WA). The results indicated that the MOE was significantly affected by both factors. IB was affected significantly by weight ratio of different glue types, with 17 wt% more MDI resin portion in the core layer of the denim boards, the IB for total adhesive content 15% fiberboard was enhanced by 306%, while for total adhesive content 25% fiberboard, enhanced by 205%. TS and WA, with higher adhesive content used in denim boards' fabrication, and more pMDI portion in the core layer of the boards, the boards' TS and WA was reduced by up to 64.2% and 78.8%, respectively.
