One of the essential difficulties encountered while preparing a piece for a pre-professional player is defining the piece's technical challenges and doing exercises or etude studies accordingly. Based on this fact, in my thesis, I described the technical challenges of Edouard Nanny's Dragonetti A Major concerto under the headings and suggested technical studies suitable for these difficulties. The titles represented are string crossing, bow strokes, thumb position and vertical-horizontal approaches, harmonic arpeggios and horizontal playing in harmonics, intonation and shifting, and double stops. In the last step of each heading, I associate these technical studies with an excerpt from a more advanced piece than this concerto in the double bass repertoire. Accordingly, the thesis aims to define a working path for Nanny's Dragonetti A Major Double Bass Concerto and, at the same time, to be a preliminary preparation for the more technically challenging works of the repertoire.

With the advent of autonomous systems and deep learning systems, safety pertaining to these systems has become a major concern. The existing failure analysis techniques are not enough to thoroughly analyze the safety in these systems. Moreover, because these systems are created to operate in various conditions, they are susceptible to unknown safety issues. Hence, we need mechanisms which can take into account the complexity of operational design domains, identify safety issues other than failures, and expose unknown safety issues. Moreover, existing safety analysis approaches require a lot of effort and time for analysis and do not consider machine learning (ML) safety. To address these limitations, in this dissertation, we discuss an artificial-intelligence driven model-based methodology that aids in identifying unknown safety issues and analyzing ML safety. Our methodology consists of 4 major tasks: 1) automated model generation, 2) automated analysis of component state transition model specification, 3) undesired states analysis, and 4) causal factor analysis. In our methodology we identify unknown safety issues by finding undesired combinations of components' states and environmental entities' states as well as causes resulting in these undesired combinations. In our methodology, we refer to the behaviors that occur because of undesired combinations as off-nominal …

Children with disabilities are three to four times more likely to be abused than their non-disabled peers due to the impact of challenges related to behavior, cognition, language, social skills, and communication skills. In September of 2018, the Council for Exceptional Children (CEC) specifically noted the need to establish maltreatment prevention and response curricula and promote research and advocacy surrounding maltreatment of children with disabilities. One common curriculum recommended is Kidpower®. While Kidpower® shows promise in increasing people safety skills and offers some basic accommodations for use with disabled populations, a complete accommodation plan for deaf or hard of hearing students has not been developed. The purpose of this study was to explore how Kidpower® curriculum could be accommodated to meet the unique needs of deaf and hard of hearing students from the perspective of the deaf education community, including deaf adults, deaf education teachers, deaf education teacher preparation faculty, and parents with deaf or hard of hearing children. A combination of focus groups and interviews were utilized to review lessons and homework from the Kidpower® curriculum. Participants gave feedback on obstacles and ideas for accommodations and modifications that would mediate the challenges. Data were inductively coded and analyzed for …

Switchable adhesives using stimuli-responsive systems have many applications, including transfer printing, climbing robots, and gripping in pick and place processes. Among these adhesives, electroadhesive surface can spontaneously adjust their adhesion in response to an external electric field. However, electroadhesives usually need high voltage (e.g. kV) and the adhesion disappears upon turning off the signal. These limitations make them complicated and costly. In this research, we demonstrated a gold-coated silica microsphere (GCSM) with highly switchable and memorable adhesion triggered by a relatively small voltage (<30 V). In the experiment, a silica microsphere with a diameter of 15 μm was glued to a tipless atomic force microscope (AFM) cantilever. The nanoscale thick gold coating was sprayed on the surface of the microsphere by a sputter coater. AFM was used to explore the tunable adhesion with an external voltage at different relative humidity (RH). The results revealed that when applying a positive electrical bias at high RH, the adhesive force increased dramatically while it decreased to almost zero after applying a negative potential. Even if the bias was turned off, the adhesive force state could still be kept and erased on demand by simply applying a negative voltage. The adhesive force can be …

Making Sense of Things is a piece composed through consideration of the relationship between music, meaning, and materiality. The piece, written for voice, flute, percussion, and live electronics, explores topics of the "sensible" and "nonsensical" in music, moving through a variety of sonic episodes that feature different notational approaches, electronic textures, technical instrumental practice, and theatrical elements in order to explore a variety of expressive possibilities while unified around the central musical ideas of scratching sounds and metal bars. The critical essay examines the relationship between the piece and the theoretical writings which inspired it. Reading through the work of Gilles Deleuze and Félix Guattari, I examine the relationship between Making Sense of Things and new materialist discourses, affect theory, and semiotics.

MakerBuses are travelling makerspaces that deliver hands-on tools and resources to community-wide locations to foster 21st century learning and development. Often found in K-12 schools, MakerBuses provide accessible and tangible learning opportunities for all learners, even in the most underserved communities. This single, typical case study provided a foundational look at how one MakerBus started as a simple idea and evolved into a learning experience used throughout the community it serves. Through discovery it was evident that accessibility, community outreach, tool distribution, and active learning were the critical elements that made this makerbus a unique tool for education.

Contentious interactions may arise between a tax professional and client upon a disagreement over a tax position. In an increasingly competitive tax return preparation market, these contentious interactions represent a significant threat to tax practitioners' client satisfaction and retention objectives. I conduct an experiment in which I examine the effect of three factors on tax clients' (1) likelihood to accept the advice of the tax accountant and (2) likelihood to switch tax accountants upon receiving professional advice counter to their preferred tax position. The three factors are: (1) clients' antagonistic narcissism; (2) clients' relationship with the accountant; and (3) how the advice is framed by the tax accountant. The results are based on a sample of 93 taxpayers. First, this study examines how clients' measured levels of narcissistic antagonism (hereafter, antagonism) impacts their reaction to "being told no" by their tax professional. Results indicate that upon the receipt of advice contrary to their preferences, highly antagonistic clients are more likely to (1) engage in a contentious interaction with their professional and (2) switch to a new tax professional. Supplemental path analyses document that individuals with high levels of antagonism cognitively react to instances of "being told no" by simultaneously devaluing …

This anthology of late 19th- and early 20th-century Czech opera arias for soprano focuses on works that lack existing scholarship, bridging the language gap through translations and pronunciation materials for English-speaking singers. Its 24 arias supplement the works of Smetana, Dvořák, and Janáček with those of contemporaneous composers Karel Bendl, Zdeněk Fibich, Josef Bohuslav Foerster, Karel Kovařovic, Vítězslav Novák, and Otakar Ostrčil. Its musicological scope provides vignettes of the musical-cultural landscape of Czech opera around the turn of the 20th century, the transformation of Czech declamation during that period, and the language knowledge needed to sing the works thereof. Chapter 2 elucidates the methodology used in the anthology's phonetic transcriptions and discusses the unique articulatory demands of singing in Czech. Chapter 3 grounds contemporaneous discussion of Czech declamation as late 19th- and early 20th-century composers and librettists sought to shape a musical voice suited to the features of their language. The following chapter is a look at Janáček's unique solution to this challenge. In Chapter 5, the relationship between criticism and composition is examined for these two faces of Czech modernism. Finally, Chapter 6 includes new performance editions of the arias curated for the anthology. Each aria is accompanied by …

The period between 1880 and 1885 was a significant time in Claude Debussy's life and compositional career. 1880 marks the date of his first published composition, "Nuit d'étoiles," and 1885 is the year in which he began his two-year tenure in Rome after winning the coveted Prix de Rome in 1884. During the intervening time Debussy composed about forty songs. Scholarly literature, especially analytical literature, tends to focus heavily on music in Debussy's mature style, often casting his early compositions in an unfavorable light. Writing on Debussy is scattered with references to the early songs but authors almost always situate them on one end of a continuum that shows an evolution of compositional style culminating in maturity. Such a view tends, if only tacitly, to regard early works as inferior instances of juvenilia rather than works worthy of study in their own right. In this dissertation I establish a foundation for regarding Debussy's early songs as significant compositions in their own right, independent from anachronistic comparisons with his more mature compositional style, and provide justification for considering the songs as a unified, identifiable repertoire within Debussy's larger œuvre. Using a modified Schenkerian analytical approach, I identify consistencies among the songs …

Doing, undoing, and redoing gender debates have established the omnirelevance and performativity of gender. Yet, little is known about the ways that individuals "do" gender in spaces that provide the opportunity for norms to be disrupted, such as subcultures. This study offers an empirical investigation into the performance of gender within the subculture known as EDM (electronic dance music) culture. Using 20 in-depth interviews that were conducted virtually, I analyze the way ravers experience and give meaning to gender within the EDM culture. I find that individuals within the EDM culture can participate in the doing, undoing, and redoing of gender and do so through the embodiment of their subcultural beliefs and ideology, known as PLUR (peace, love, unity, and respect). I argue that the embodiment of PLUR is gendered, and describe the body-reflexive practices that are associated with PLUR.

Piezoelectricity in two-dimensional (2D) transition metal dichalcogenides (TMDs) has attracted significant attention due to their unique crystal structure and the lack of inversion centers when the bulk TMDs thin down to monolayer. Although the piezoelectricity effect in atomic-thickness TMDs has been demonstrated, they are not scalable. Herein, we demonstrate a piezoelectric effect from large-scale, sputtered MoS2 and WS2 using a robust defect-engineering based on the thermal-solvent annealing and solvent immersion process. This yields a higher piezoelectric output over 20 times after annealing or solvent immersion. Indeed, the piezoelectric responses are strengthened with the increases of defect density. Moreover, the MoS2 or WS2 piezoelectric device array shows an exceptional piezoelectric sensitivity with a high-level uniformity and excellent environmental stability under ambient conditions. A detailed study of the sulfur vacancy-dependent property and its resultant asymmetric structure-induced piezoelectricity is reported. The proposed approach is scalable and can produce advanced materials for flexible piezoelectric devices to be used in emerging bioinspired robotics and biomedical applications.

Autonomous vehicles have made milestone strides within the past decade. Advances up the autonomy ladder have come lock-step with the advances in machine learning, namely deep-learning algorithms and huge, open training sets. And while advances in CPUs have slowed, GPUs have edged into the previous decade's TOP 500 supercomputer territory. This new class of GPUs include novel deep-learning hardware that has essentially side-stepped Moore's law, outpacing the doubling observation by a factor of ten. While GPUs have make record progress, networks do not follow Moore's law and are restricted by several bottlenecks, from protocol-based latency lower bounds to the very laws of physics. In a way, the bottlenecks that plague modern networks gave rise to Edge computing, a key component of the Connected Autonomous Vehicle system, as the need for low-latency in some domains eclipsed the need for massive processing farms. The Connected Autonomous Vehicle ecosystem is one of the most complicated environments in all of computing. Not only is the hardware scaled all the way from 16 and 32-bit microcontrollers, to multi-CPU Edge nodes, and multi-GPU Cloud servers, but the networking also encompasses the gamut of modern communication transports. I propose a framework for negotiating, encapsulating and transferring data …

An important question in teaching language is, what accounts for the emergence of either receptive or expressive labels when teaching only one of them? The teaching procedures in the present study were intended to reproduce the natural development of bidirectional naming in which caregivers comment on the items a child is interacting with and children echo those vocalizations they hear. Thus, the only vocalizations presented by the researcher during teaching occurred after the learner pointed to a specific stimulus, and were specific to the stimulus being targeted. These vocalizations are referred to in this study as stimulus-specific consequences. The purpose of this research was to investigate if the stimulus-specific consequences could become discriminative stimuli for receptive labels, and lead to the emergence of expressive labels. Three studies were conducted, each with four adults. Results demonstrated that using a stimulus-specific consequence during teaching led to receptive labels for all participants, but led to the emergence of expressive labels for only four participants. In other words, bidirectional naming did not occur for the majority of participants. Factors that may improve interrelations between receptive and expressive labels were analyzed, but further evaluations are needed to account for the inconsistent demonstrations of naming.

This dissertation examines the impact of FDI on peace in civil conflict-experienced states. While economic grievances have often been pointed out as a major cause of civil war within the literature, scholarship on post-conflict peace has focused mainly on political settlements, such as one-sided victories or power sharing, largely ignoring the importance of economic conditions. Thus, this dissertation aims to examine how FDI can affect sustainable peace in conflict-experienced states in terms of prevention of conflict recurrence and regime stability. FDI can be conducive to peace during/after civil conflicts, as it can bring capital which can be used for economic reconstruction and development in conflict-experienced states. Furthermore, this dissertation focuses on the impact of bilateral FDI. When a third party intervenes in a conflict management process and the third party has a great deal of economic interaction with the conflict experienced state, this economic interdependency will affect the third party's motivation to make the conflict-experienced state stable. It also provides third-party with greater leverage over peace efforts. Eventually, this third-party leverage will affect peace during/after civil conflicts. This dissertation is built around three interrelated empirical chapters: (1) determinants of FDI in conflict-experienced states, (2) the impact of FDI on conflict …

Children experience a multitude of benefits in response to interactions with nature. Despite documented effects, children have increasingly spent less time outdoors over the last century and experienced higher rates of physical and emotional illnesses. Although child-centered play therapy (CCPT) is a culturally and developmentally responsive mental health treatment for children, researchers have limited study of environmental structure and materials employed in the therapeutic process of CCPT. In this study, I sought to further research on the integration of nature with CCPT by providing CCPT in an outdoor, contained playroom equipped with traditional CCPT toys and additional nature materials. Participants were 13 children in the southwestern U.S. with parent-reported attentional or self-regulation concerns (9 males, 6 females; ages 5-10, mean age M = 8.0). Parents reported participants' racial identities were 13% Black (n = 2), 13% Latinx (n = 2), 7% Turkish (n = 1), and 67% White (n = 10). Participants received 8 weeks of twice-weekly CCPT in an outdoor playroom. Results of two repeated measures ANOVAs revealed statistically significant improvement in attention on the Brown EF/A Scales and statistically significant improvement in social-emotional competencies on the SEARS-P. Results of this study illustrate the possible benefits of theoretically integrating …

This dissertation argues that the core of building smart cities is through the procurement and implementation of smart city technologies (SCTs) by either individual (i.e., smart city) or collaborative endeavors (i.e., smart governance). Given that urbanization problems (e.g., air pollution) usually spill over city boundaries, building smart cities as silos may not solve these problems. Therefore, utilizing smart governance in SCT procurement and implementation should be a better approach. Considering the potential benefits of smart governance, this dissertation addresses three overarching questions: (1) What is a smart city? (2) What is smart governance? and (3) Why do some cities choose to participate in smart governance while others do not? By developing a typology of smart governance, this dissertation categorizes three levels of smart governance based on cities' participation in cooperative procurement and implementation of SCTs. Data collected from the 2019 Smart Governance Survey confirm that the level of smart governance does vary among Texas cities. Applying transaction costs and institutional collective action (ICA) frameworks, the dissertation finds that public managers' perceptions on transaction costs and joint gains as well as cities' extant ICA mechanisms affect cities' participation in smart governance.

Research in scholarly communication is usually limited to the use and dissemination of scientific material by scholars. This excludes the transfer of knowledge from research producers to service providers. Some may argue the primary function of science is to investigate the conditions in the lab so everyday interactions with the environment are more effective and efficient. This is the underlying philosophy of the science of behavior analysis. Comprised of a basic science, an applied science and a philosophy the field of behavior analysis relies on research developments to inform effective practice. Guided by dissemination processes studied in information science, this investigation revealed the content layer in behavior analysis is primarily comprised of journal articles. Ninety four percent of the research artifacts cited in the current content layer are from journal articles. Other dissemination channels used to develop the behavior analytic content layer included scientific magazine articles, oral reports, dissertations and theses, and unpublished manuscripts. The information use environment for professionals in this field is very different than that of the scholars; most professionals do not have access to a university library. Therefore, the research producers are disseminating developments via communication channels some service providers cannot access. This investigation reveals the …

Francis Bacon (1561-1626) is recognized as a founder of the modern scientific project and a forerunner of the modern era of political thought. He advocated the development of an active science that would enable human beings to control nature in order to relieve man's estate. To accomplish this, Bacon argues that we must reconstruct all arts and sciences upon a more solid foundation. In reconstructing the arts and sciences, Bacon subtly changes the meaning of foundational religious, political, and scientific notions in order to better suit his project of progress. As the inheritors of his vision, turning to Bacon helps recover foundational considerations that have been forgotten as a result of his success. This dissertation approaches Bacon's thought through an analysis of his New Atlantis, a fable that envisions the completion of his project. I also turn to his other political, scientific, and religious works as appropriate to supply what is omitted in the fable. I find that although his revision of religious, scientific, and political foundations is conducted subtly they are nevertheless revolutionary, and essential for preparing the various outlooks that characterize the modern world.

Value-added models (VAMs) have become widely used in evaluating teacher accountability. The use of these models for high-stakes decisions making has been very controversial due to lack of consistency in classifying teachers as high performing or low performing. There is an abundance of research on the impact of various student level covariates on teacher value-added scores; however, less is known about the impact of teacher-level and school-level covariates. This study uses hierarchical linear modeling to examine the impact of including teacher characteristics, school characteristics, and student demographics aggregated at the school level on elementary mathematics and reading teacher value-added scores. Data for this study was collected from a large school district in north Texas. This study found that across all VAMs fitted, 32% of mathematics teachers and 37% of reading teachers changed quintile ranking for their value-added score at least once across all VAMs, while 55% and 65% of schools changed their quintile ranking of value-added scores based on mathematics and reading achievement, respectively. The results show that failing to control for aggregated student demographics has a large impact on both teacher level and school level value-added scores. Policymakers and administrators using VAM estimates in high-stakes decision-making should include teacher- …

Sprint acceleration training has been highly researched and found that resistance sleds are one of the most effective tools for maximizing training adaptations. The resistance sled is being used by many of the world leaders in athletic training but has yet to be researched for the kinetic and kinematic effects some of its key components cause. The aim of this study was to better understand the effects of the attachment height on the sled and sled rail material on the user's trunk lean and jerking effect caused by the sled. This was done because it was hypothesized that the attachment height has a direct impact on trunk lean and sled rail material has a direct impact on jerk caused by the sled. To test these assumptions, experimental and theoretical data was collected using a single subject study analyzing trunk lean and acceleration values of the sled. The results presented a significant decrease in trunk lean (more horizontal line of action) when the attachment height was raised. Additionally, no significant values were attained to support the assumption that by modifying the sled rail material, jerking effects will decrease. The results indicate that there is a direct correlation between attachment height and …

Where people go between evacuation and recovery remains an understudied aspect of disaster research. Whether experiencing multiple displacements, permanent displacement, or undergoing recovery in a damaged dwelling, the spatial and temporal dimensions of disaster displacement can have direct impacts on the recovery experiences of survivors. Pulling from focus group data gathered in 2017 from Hurricane Sandy survivors in New Jersey, this qualitative research focuses on the experiences of those who recovered in-situ, or within their damaged dwelling following the storm, and the various ways this non-displacement impacted their recovery. A content analysis following a grounded theory approach produced the emergent themes of the in-situ experience, including: a lack of suitable shelter, an exposure to secondary hazards, and an inability to achieve satisfactory emotional recovery. This study contributes to the growing body of literature surrounding recovery experiences, and it introduces valuable insights into the challenges that survivors face while recovering in-situ.

This thesis demonstrates a queer perspective stemming from a qualitative analysis of data gathered in interviews with LGBTQ+ people to analyze a transforming ethos of gayborhoods and queer desires. In particular, the research focuses on the interactive relationship between self-identified lesbian, gay, bisexual, transgender, and queer (LGBTQ+) participants; the cyberspace(s) of LGBTQ+ mobile-dating applications (apps); and tangible urban places. The topic of gayborhood demise and whether such places are worth saving has been debated by scholars and journalists for the last decade. The demise of gayborhoods is often thought to be a symptom of neoliberal urban processes such as gentrification within the context of the post-gay era and broader societal acceptance of homosexuality. This means the question of "if the gayborhood is worth saving" is inherently imbedded in an assumption that homosexuality is not viewed or treated as different or lesser than heterosexuality. In this imagined post-gay era, gayborhoods are declining because the dangers posed to the LGBTQ+ population are purported to no longer exist, so there is no longer a need for designated queer and/or safe places. This research destabilizes the assumptions embedded within the conception of the post-gay era by asking whether the gayborhood meets the needs and …

Like many institutions of high education throughout the United States, the University of North Texas requires all students to pass introductory United States History courses. While the purpose of these courses should be to create a population well versed in U.S. history and sociopolitical and economic context, the foundational textbooks utilized in these courses promote American exceptionalism and U.S. supremacy. Their omission of the complex and controversial history of the United States creates a false master narrative based on an idealized version of U.S. history. Even textbooks that include diversity continue to uphold a progressive master narrative that ignores issues of systemic racism, sexism, and homophobia. My theoretical analysis of the required textbooks, Exploring American Histories: A Survey with Sources, is applicable to all introductory U.S. history textbooks. Decolonialism, critical race, and intersectional feminism are theoretical lenses that disentangle and highlight otherwise invisible aspects of American exceptionalism and the serious consequences of the subjugation of subaltern historical narratives. This thesis applies theory with examples of how textbooks or supplemental teaching can expose foundational oppression, violence, and discrimination to teach students critical thinking and help them see connections between the past and their present.

Although one-to-one technology programs are rapidly expanding in secondary schools, the literature about how to effectively leverage these programs to improve teaching and learning is relatively small. Little guidance is available for school leaders attempting to improve teachers' willingness and ability to incorporate technology effectively into their instruction. The purpose of this mixed-methods case study was to discovery what supports school leaders provide to promote high levels of computer self-efficacy and transformational digital pedagogies in one-to-one learning environments. Data were collected from English language arts, Social Studies, and science teachers in three high schools in a suburban school district in northeast Texas using an online survey, eight virtual semi-structured interviews, and two virtual focus group interviews. Data were analyzed using descriptive statistics and deductive and inductive analysis. The findings of the study reveal most teachers perceived their ability to effectively deliver digital instruction as strong, and most were able to incorporate technology into their lessons at transformational levels. The following themes emerged from data regarding teachers' perceptions of support: shared vision, realistic and supportive climate, collaboration, encouragement, job-embedded professional learning, continuous improvement, equity, and safe, legal, and ethical use. The findings of this study serve as a foundation for understanding …
