The implementation of professional learning communities (PLCs) has led to systemwide reform within school districts and campuses regarding how campus leaders support the teachers' collaborative work and continued professional learning. Current research emphasizes the importance of campus administrators cultivating an environment where PLCs can flourish and ensuring that PLC teams have the resources to work effectively. However, campus administrators simply putting these supports in place does not make them effective. This study sought to explore campus leader and teacher perceptions of administrator actions that support PLCs for teachers in core-content subjects at two suburban north Texas high schools. An explanatory sequential mixed methods research design was utilized, and three data collections tools were used: an electronic survey, interviews with campus administrators and teachers, and the analysis of campus and PLC artifacts. Survey data indicated that participating teachers had an overall positive perception of the current campus practices which support PLC teams. Teacher interview data revealed that teachers preferred that campus administrators take a neutral role in PLC team meetings, that administrators ensure PLC teams are meeting the established campus PLC expectations, and that administrators observe the team, listen, and ask questions to help the team. Campus administrators viewed their actions …

How do religions and nationalism interact in secular democracies? With its history of nationalism based on religious ideologies, and the subsequent forced separation of state and religion, Japan provides a valuable case to examine how religion and nationalism interact and affect the politics of a secular state. The purpose of this dissertation is to understand and synthesize the divide within the literature regarding the idea that Shinto is fundamentally nationalist in nature. Due to Shinto's historical ties to Japanese nationalism, it is clear that religion and nationalism played a role in Japanese politics in the past. However, with Japan's transition to democracy and the constitutional provision of the separation between religion and state, religion's effect on nationalism in Japan has become blurred contemporarily. In order to explore these relationships between Shinto, nationalism, and Japanese politics, I investigate how political groups and religious organizations influence nationalist sentiment in political institutions and public opinion in Japan using the Japanese Value Orientations survey and an original dataset. I find that even though the evidence is mounting against the accuracy around the idea of State Shinto and the fundamentally nationalist nature of Shinto, the narrative persists. The existence of nationalist circles perpetuates these narratives, …

The dissertation examines factors influencing nonprofit organizations' contribution to collaborative governance for climate change adaptation and nonprofit roles in the collaboration. Why an organization collaborates with others has long been a concern of scholars. However, in a majority of empirical studies, collaboration has been considered as a dichotomous concept. To fill the gap, this study considers organizations' contribution to collaboration, i.e., collaboration level in terms of power, joint activities, human resource, funding, and information sharing. To understand contribution of nonprofits to collaboration for climate change adaptation, this research employs the institutional collective action framework suggesting that organizations work together when expected benefits are greater than collaborative risks. Survey data from 101 nonprofit private organizations (beyoungri mingan danche) in South Korea, which are legally defined in the Assistance for Nonprofit, Nongovernmental Organizations Act, are analyzed. Finding is that government funding and social relationship are strongly associated with nonprofit contribution to collaboration, highlighting that the financial stability of nonprofit organizations and mutual trust among entities based on routine interaction are critical motives for nonprofit collaboration. Finding also reveals that Korean nonprofits mainly play a role as social capital creators in climate change adaptation. The finding also highlights that Sang Bu Sang Jo …

The dissertation seeks to rediscover Julius Schloss, a German Jewish composer victimized by the Nazis. Except for the promising start of his career in his early years, Schloss suffered a hard life as an exiled refugee. However, his unusual experiences inspired him to compose two Chinese Rhapsodies during his last years of exile in Shanghai, in which he synthesized Western composition techniques and Chinese folk materials, amalgamating influences from both Western and Eastern music cultures. Focusing on Schloss's First Chinese Rhapsody, the dissertation explores how Schloss links the new to the old, the West to the East, through an analysis of the way he employs Chinese folk song material and serial polyphonic voice-leading in his post-tonal musical language. Since the Rhapsody has both serial and polyphonic voice-leading aspects, both are analyzed, showing how they are integrated in the form.

The two fields of acousmatic music and site-specific conceptual art take strikingly different approaches to the notions of space and place. In this document, I describe how these two areas of aesthetic research diverge and relate to each other, focusing on how their unique approaches can be implemented in the practice of site-specific music composition. The first part of this document surveys the distinctive features of each of these fields, describing the particular differences between them in their approach to space and place. The contradictions between the two approaches are then briefly analyzed in reference to Georgina Born's understanding of music as fundamentally multitextual. In the second part of the document, I describe in detail how I implemented a site-specific approach when composing "…threaded through," a 16-channel audio, 6 video, site-specific installation for the UNT College of Music Main Building. In this, I describe how both the space and place of the UNT College of Music Main Building influenced my musical choices, visual content, and approach to audio and visual spatialization. The final part of the document contains a detailed score for realizing "…threaded through" in the location of the UNT College of Music Main Building.

In 2016, An estimated 15,000 people representing 400 Indigenous Nations and non-indigenous allies gathered at the Standing Rock Sioux Reservation in solidarity against the Dakota Access Pipeline to protect Mni Sose, the Missouri River. They became known as the Water Protectors. This dissertation analyzes the response in environmental philosophy journals to the #noDAPL protest at Standing Rock. Even though the Stand at Standing Rock became one of the most important and monumental environmental protests of the last decade, neither Standing Rock nor the Water Protectors appear in environmental philosophy journals at all--not once. Why? I suggest a possible answer by exploring the Stand of the Water Protectors as a moment in a much longer continuous history of resistance to settler colonialism. Settler colonialism attempts to facilitate the erasure of Indigenous populations by colonial ones, in order to gain access to territory—to land. The omission of Standing Rock from environmental philosophy journals represents the ease with which environmental philosophy can become complicit in the project of settler colonial erasure and replacement through absence. Drawing on Indigenous land-based philosophies of kinship, Latin American decolonial philosophy, settler colonial theory, and frameworks of Indigenous environmental justice, I show how the geo-politics of colonialism have …

Ugolino (c. 1380-1457) wrote one of the largest treatises on music theory in the first half of the fifteenth century. This work, the "Declaratio musicae disciplinae," is comprised of five books that cover everything a musician of the era would need to know, from plainchant to harmonic proportions, from musica practica to musica speculativa. However, the treatise has received contradictory interpretations by modern scholars, some viewing it as mainly practical, others as mainly theoretical. I argue that in Book 2, which deals with counterpoint, Ugolino crystallizes the relationship between theory and practice, while offering distinctive contrapuntal practices. Ugolino presents a unique view music's place in the structure of knowledge, one which is highly dependent on Aristotelian philosophy. He posits that music is a science and that it is a branch not of mathematics, as it had traditionally been categorized, but of natural philosophy. This viewpoint shapes the entire treatise and is evident in the book on counterpoint. There, he presents an Italian tradition of teaching counterpoint known as the "regola del grado." Ugolino is the first author to present this tradition entirely in Latin. In addition, he offers an unusual description of musica ficta. In it, he presents a diagram, …

The production and control of antihydrogen at very low temperatures provided a key tool to test the validity for the antimaterial of the fundamental principles of the interactions of nature such as the weak principle of equivalence (WEP), and CPT symmetry (Charge, Parity, and Time reversal). The work presented in this dissertation studies the collisions of electrons and positrons in strong magnetic fields that generate magnetobound positronium (positron-electron system temporarily bound due to the presence of a magnetic field) and its possible role in the generation of antihydrogen.

This dissertation focuses on the path planning of unmanned aerial vehicle (UAV) swarms under distributed and hybrid control scenarios. It presents two such models and analyzes them both from theory and practice. In the first method, a distributed formation control strategy for UAV swarm based on consensus law is presented. This model makes use of the fundamental concepts of leader-follower structure, social potential functions, and algebraic graph theory to jointly address flocking and de-confliction in the formation control problem. The impact of network topology on formation control is analyzed. It is shown that the degree distribution of the network representing the multi-agent system defines the rate at which formation is attained. Conditions for convergence and stability are derived. In the second method, a hybrid framework for path planning and coverage area by UAV swarms is presented. This strategy significantly improves the current labor-intensive and resource-constraint operations in aquaculture farms. To monitor the farms periodically, an optimized back-and-forth flight path based on the Shamos algorithm is utilized. A trajectory tracking strategy for UAV swarms under uncertain wind conditions is presented.

Anthony Plog's Concerto for Flute and Wind Ensemble is a substantial but relatively unknown work from the composer's early compositional period. It deserves wider exposure and recognition in the repertoire for solo flute and wind ensemble, given its accessibility for both the soloist and the ensemble.

In this work, we demonstrate the mechanism for etching exfoliated graphene on SiO2 and other technological important substrates (Si, SiC and ITO), using low-energy electron sources. Our mechanism is based on helium ion sputtering and vacancy formation. Helium ions instead of incident electrons cause the defects that oxygen reacts with and etches graphene. We found that etching does not occur on low-resistivity Si and ITO. Etching occurs on higher resistivity Si and SiC, although much less than on SiO2. In addition, we studied the degradation mechanism of MoS2 under ambient conditions using as-grown and preheated mono- and thicker-layered MoS2 films. Thicker-layered MoS2 do not exhibit the growth of dendrites that is characteristic of monolayer degradation. Dendrites are observed to stop at the monolayer-bilayer boundary. Raman and photoluminescence spectra of the aged bilayer and thicker-layered films are comparable to those of as-grown films. We found that greater stability of bilayers and thicker layers supports a previously reported mechanism for monolayer degradation involving Förster resonance energy transfer. As a result, straightforward and scalable 2D materials integration, or air stable heterostructure device fabrication may be easily achieved. Our proposed mechanisms for etching graphene and ambient degradation of MoS2 could catalyze research on realizing …

Ceramics have a wide variety of applications due to their unique properties; however, the low fracture toughness leads the formation and propagation of unpredictable cracks, and reduces their reliability. To solve this problem, self-healing adaptive oxides were developed. The aim of the work is to gain new insights into self-healing mechanisms of ceramics and their application. Binary oxide systems were investigated that are at least partially healed through the extrinsic or intrinsic addition of silver or silver oxide to form ternary oxides (e.g., Nb2O5 + Ag → AgNbO3). Sintered pellets and coatings were tested. For self-healing TBCs, model systems that were studied include YSZ-Al2O3-SiC, YSZ-Al2O3-TiC, YSZ-Al2O3-Nb2O5, and YSZ-Al2O3-Ta2O5. Laser cladded samples and sintered pellets were produced to test. The healing process occurs due to the formation of oxidation products and glassy phases depending on the self-healing mechanism. X-ray diffraction was used to explore phase evolution, chemical compositions, and structural properties of these samples. SEM equipped with EDS was used to investigate the chemical and morphological properties for the cross-sectional area. Pin-on-disc test was applied to test tribology performance for Nb2O5-Ag2O system, and infiltration test was applied to test CMAS-resistance for TBCs at elevated temperature. The improvements in the performance of …

Vietnam currently faces a social skills deficit among college graduates. This lack of sufficient social skills significantly affects Vietnam's economy where it is one of the main factors that drives higher unemployment in Vietnam. Research has shown that although social skills have been increasingly perceived by employers as one of the most important factors for graduate employability and career success, the absence of social skills training in colleges and universities have caused graduates to be ill-prepared for the workplace, which lead to dissatisfactions among employers and complications when seeking for potential hires in Vietnam. Therefore, this study aims to examine and compare perceptions of Vietnamese college graduates and employers on graduates' social skill performance. Given the objectives of this study, an online survey was distributed to potential participants across Ho Chi Minh City, Vietnam. Analysis of the responses not only demonstrated a disconnect of perceptions between employers and newly hired graduates (NHGs) on how these two groups rated graduates' performance of interpersonal skills but also revealed a mismatch in the perceptions of the comparing groups on how they perceive the importance of social skills in graduate employment. As a result, it is recommended that Vietnam need to promote and support …

Data from this dissertation was obtained from the Texas Behavioral Risk Factor Surveillance System (BRFSS). The Texas BRFSS questionnaire used a cross-sectional retrospective research design while asking questions about individuals' exposure to adverse childhood experiences (ACEs) and included 11 questions. The sample included 9096 individuals over the age of 18 who had exposure to at least one ACE. An ACE score was calculated for all participants and were divided into two groups (less than 4 ACEs and more than 4 ACEs) to compare whether differences in ACE score would impact participating in routine health screening or not. Additionally, whether different kinds of ACEs would impact health screening was also examined. Logistic regression was used to assess whether different kinds of ACEs impact participation in routine health screening. This study found that individuals with a history of childhood adversities including experiencing childhood emotional abuse, living in a dysfunctional household impeded them from participating in routine health screenings. It is recommended that both primary care physicians and mental health providers to use motivational interviewing while interacting with patients with ACE histories. It is also suggested that using trauma-informed care (TIC) in primary care can help patients talk about their abuse histories and …

Korean art songs are valuable cultural assets that exhibit their own cultural spirit and ethnicity, however, they are not introduced to Western singers because of the language barrier. As there are European-language diction books for singers used in pedagogy, this dissertation introduces Korean diction for non-Korean-speaking singers by using the International Phonetic Alphabet (IPA) to pronounce Korean ‘Hangeul'. Moreover, this document aims to help singers enter into a new world of Korean art songs by introducing ten Korean art songs selected from various compositional periods, along with transcriptions using the IPA, transliterations, translations, and the musical scores.

Female collegiate athletes have been identified as a group at risk of developing eating disorders (EDs) and unhealthy weight control behaviors. Interventions grounded in cognitive dissonance theory and those that incorporate mindfulness-based interventions have shown improved body image and reductions in internalization and ED symptomatology over time in female non-athletes. However, few studies have examined the efficacy of intervention programs among female athletes, and, despite early promising results, previous research has been limited in several ways (e.g., methodology, small sample size). The purpose of this study was to conduct a long-term (i.e., three years) qualitative follow-up evaluation of Bodies in Motion (BIM), an ED prevention program developed specifically to acknowledge the unique experience and needs of female athletes with respect to their bodies as women and athletes. Results indicate that, similar to their initial experiences, now-retired athletes reported increased awareness of sport and societal messages and their impact on body image, shifted perspectives in their view of themselves and their bodies, and ongoing use of skills to manage body image in their lives. Further, with the passage of time, athletes continued to report a positive experience in the program and the utility of Bodies in Motion as they navigated challenging …

No published studies to date examined the practices in creation or adoption of metadata in cultural heritage institutions or evaluated metadata in bibliographic databases in the Arabian Gulf counties and assessed its potential interoperability in the aggregation that would provide a central point of access to bibliographic databases of cultural heritage institutions. This exploratory study aimed to address this gap with the goal of: (1) developing understanding of the current state of information representation and knowledge organization in cultural heritage collections in Arabian Gulf countries, and (2) exploring perspectives for future developments such as creating regional large-scale portals similar to Digital Public Library of America, Europeana etc. that facilitate discovery by aggregating metadata and possible barriers to these developments.. The study is focused on a Kuwaiti, Qatari, and Omani libraries, museums, and archives. The mixed-methods research combined semi-structured interviews of the bibliographic database managers at 15 cultural heritage institutions and in-depth content analysis of a sample of 412 metadata records that represent items in these bibliographic databases for accuracy, completeness, consistency, use of knowledge organization systems, etc. This study findings make a research contribution important for evaluating the feasibility and planning of future aggregations of cultural heritage bibliographic databases. Results …

Managers rely on analytics to make decisions and the choice of the analytical method can influence their decision-making. This dissertation considers three cases and examines how the choice of analytical methods influence interpretations and implications. These areas are communication for health-related information in social media, health information technology investment by hospitals as it relates to patient satisfaction, and health related expenditure policies of countries. These studies develop theoretical models and empirically test them on primary or secondary data, comparing the performance of popular analytical methods. The conduct of these three studies contributes to a better understanding about the choice of analytical methods and allow development of a heuristic approach by offering guidelines for selecting an appropriate methodology. They demonstrate the value of heuristic approaches for use with non-traditional and traditional statistical methods, as the information gained from non-traditional methods (NNs) provides insights into traditional statistical methods, similar to insights gained from exploratory data analysis. The studies also show the value in examining any dataset with multiple methods because they either confirm each other or fail to confirm, providing insights.

This dissertation reexamines the music-theoretical writing of Georg Jospeh Vogler (1749-1814) in light of his educational background. His system, which is often characterized as "awkward" or "self-contradictory," is actually indicative of the rationalist/humanist preferences of Vogler's main source of training: the Jesuit Order. I argue that Vogler's theories and compositional style have been marginalized, partially due to their incompatibility with the more prevalent systems of his era, which were predominantly based in empirical modes of thought.

This study investigated the associations between sleep patterns and singing voice quality in 231 adult singers of various skill levels across the United States. The four-part survey using a general questionnaire on demographics, musical background, vocal health, and three established survey instruments: the Pittsburgh Sleep Quality Index (PSQI), the Singing Voice Handicap Index-10 (SVHI-10), and the Epworth Sleepiness Scale (ESS) found that while scores were worse than normative values for the PSQI and the SVHI-10, a Pearson correlation between the two showed a moderate association. A linear regression also yielded that 8.9% of the variance in SVHI-10 scores could be predicted from PSQI scores. While further research is needed in this area, this study suggests that the amount of sleep needed for an optimal singing voice may be different from the amount needed to feel well-rested for some singers. Moreover, singers may overestimate the influence of sleep on their singing voices.

This research looks thoughtfully and deeply at the relationship between art education and signs, as defined by the French philosopher Gilles Deleuze (1964/1998). Signs, as articulated by Deleuze (1964/1998), are violent disruptions to our way of understanding the world, causing us to think again and/or re-consider what we once knew (or thought we knew). This study looks generatively at how these kinds of disruptive and disorienting moments might be mined for possibilities in art education and remind us of our own relationality. As a post-qualitative lived inquiry, it asks how might art education be-with apprenticeship to signs and what might art education do-with sign-encounters? Using the theoretical lens of transcendental empiricism and new materialism, this study considers how art educators might hold open the space of sign-encounters for oneself and one's students by turning towards the rhizomatic cut and staying with uncertainty. It is focused on the doing-with, making-with, and thinking-with of art, pedagogy, and philosophy/theory, investigating their deep entanglements in spaces of disruption and ultimately developing frame-works for engaging in this kind of work in the classroom. Drawing from Erin Manning and Brian Massumi's theory of research-creation, this research was experienced in an emergent, layered, and complex way over …

There remains a dearth of literature that explains with no ambiguity, the complex relationships that exist between adverse childhood experiences (ACEs) and resilience, as well as school engagement and school in individuals with a co-occurring diagnosis of autism spectrum disorder (ASD) and attention deficit hyperactive disorder (ADHD). This study seeks to fill this missing gap in the literature. These research questions were answered using a retrospective cross-sectional study design of national secondary data from the National Survey of Children's Health (NSCH). The findings revealed that the more ACEs an individual had, the less they were likely to engage and succeed in school. A similar finding was obtained for resilience as individuals with more ACEs showed less resilience. However, counterintuitively to the hypothesis of the project, having both ASD and ADHD does not necessarily make these outcomes worse compared to having a singular diagnosis of either ASD or ADHD. The significance of this study is that it informs rehabilitation counselors as well as educators on the need for early identification of individuals with ASD and ADHD with a background of ACEs and commence interventions early enough to ensure they are more resilient and obtain improved success in school-related activities as well …

Drawing attention to an under-examined process during organizational socialization, we develop theory to explain how newcomers' new organizational roles and social identities become embedded. The process of identities becoming embedded is influenced by how an individual's preexisting identities interact with new organizational identities during socialization. Perceived harmony relationships among identities indicate if newcomers experience identities interacting in a positive or negative manner generally. Using a network perspective, we suggest that the identity embeddedness of new roles and identities are indicated by: degree centrality in an intrapersonal identity harmony network, perceived harmony with the network itself, and the perceived cost of lacking harmony with a focal identity. Newcomers are likely to be more satisfied and engaged with identities with greater embeddedness as well as find such identities more salient. Organizations can work to embed their employees' new identities through initiating identity work directed towards increasing harmony perceptions among the newcomers' new organizational identities and preexisting identities. Through helping individuals create harmony relationships among identities, organizations can improve socialization outcomes.

Research shows that having an excellent reading teacher in the classroom is key to preventing reading difficulties. However, teachers often feel unprepared to work with students experiencing reading difficulties. This can be problematic in a school that uses a multi-tiered system of support for students in which the classroom teacher is responsible for core instruction and early reading interventions. This qualitative study examined the influences on elementary teachers' instructional and assessment decisions when teaching reading to students who are experiencing reading difficulties. Data were collected through both survey and interviews and were analyzed using thematic analysis. Five themes were identified that suggest teachers' literacy instructional decisions are influenced by administrators, their knowledge of reading instruction, professional development, their beliefs about using data for instruction, and collaboration. Findings from this study provide evidence that teacher decisions are more heavily influenced by forces when teachers lack a deep understanding of their students or of effective literacy instruction. When this happens, teachers' efficacy is also affected, which research shows can affect student outcomes. Teacher decision-making is supported through professional development on effective literacy instruction and use of data for planning. Teacher efficacy improves with opportunities to work with and learn from colleagues and …
