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 …

Having a secure attachment to God may act as a buffer against stress. Secure attachment to God has been positively associated with adaptive outcomes following stress, such as higher levels of stress-related growth and fewer maladaptive symptoms including depression, prolonged grief, and traumatic distress. However, relatively few studies have empirically tested the relationship between attachment to God and resilience and posttraumatic growth. Thus, the current study explored the potential associations and pathways through which attachment to God is associated with resilience and posttraumatic growth in a sample of 303 suddenly and/or traumatically bereaved individuals. The current study found that (a) God attachment avoidance is a unique negative predictor of resilience and posttraumatic growth even when controlling for adult attachment, (b) self-compassion and meaning-making mediate the association between God attachment anxiety and resilience/posttraumatic growth, (c) secure attachment to God is associated with higher levels of resilience than insecure attachment styles, but not with posttraumatic growth, and (d) an increased number of secondary losses is associated with lower levels of resilience. I conclude by discussing my findings in light of the extant literature on attachment to God, resilience, and posttraumatic growth. By better understanding attachment to God and how it may relate …

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 this thesis, I explore the careers and songs of Florence Price and Margaret Bonds—two African American female composers who were part of the Chicago Renaissance. Price and Bonds were members of extensive, often informal, networks of Black women that fostered creativity and forged paths to success for Black female musicians during this era. Building on the work of Black feminist scholar Patricia Hill Collins, I contend that these efforts reflect Black feminist principles of Black women working together to create supportive environments, uplift one another, and foster resistance. I further argue that Black women's agency enabled the careers of Price and Bonds and that elements of Black feminism are not only present in their professional relationships, but also in their songs. Initially, I discuss how the background of the Harlem and Chicago Renaissances and racial uplift ideology shaped these women's artistic environment. I then examine how Bonds and Price incorporated, updated, and expanded versions of these ideals in their music and careers. Drawing on the scholarship of Rae Linda Brown, Angela Davis, and Tammy L. Kernodle, I analyze Price's "Song to the Dark Virgin," "Sympathy," and "Don't You Tell Me No" and Bonds's "Dream Variation," "Note on Commercial Theater," …

The intention of this thesis is to analyze the representations of masculinity in the anime series Dragon Ball Z as it aired on Cartoon Network's programming block Toonami, specifically the nature in which they were framed and how oppositional interpretations in the fandom became prevalent as a result. The series emphasizes the evolution of its central characters Goku, Vegeta, and Gohan into performing a sensitive masculinity, but there are a prevalence of images in the series that discredit this. Similarly, the way the series was advertised on Toonami placed emphasis on images of superficial violence and reinforced the masculinity that the series was attempting to move beyond. Understanding the ways fans have interpreted Dragon Ball Z on Toonami helps reveal that there is much more to a media text's influence than its themes and representations of gender.

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, …

This thesis provides a detailed description and analysis of the Mankiyali phonology, a hitherto undocumented and endangered language of northern Pakistan. The language is spoken by about 500 people in a remote mountainous area in the Mansehra district of Khyber Pakhtunkhwa Province, Pakistan. The data contained herein is a result of first-hand fieldwork with native Mankiyali speakers between 2019 and 2021. Data collection methods include recordings of naturally occurring discourse (e.g., stories, poems, conversations) and elicitation sessions with native speaker consultants. Topics covered in the thesis include an account of Mankiyali's phonemic inventory, phonotactics, a description of some phonological processes, minimal word constraints, and word stress placement.

The intention of this thesis is to analyze the figure of the post 9/11 Westerner as a modern character created from the preexisting archetype of the classic Westerner. 3:10 to Yuma (dir. James Mangold), The Assassination of Jesse James by the Coward Robert Ford (dir. Andrew Dominik), and There Will Be Blood (dir. Paul Thomas Anderson) were released in 2007 and featured post 9/11 Westerners dealing with issues of fatherhood, demonstrating the prevalence of this figure within the modern western genre. Fatherhood becomes the prism through which these characters are depicted, which becomes the main source of their anxiety. The events of 9/11 contributed to a fracture of the western myth established by the classic postwar western that results in the post 9/11 Westerner attempting to reclaim a similar mythic status. The post 9/11 Westerner becomes an inversion of the classic Westerner seen through his insecure masculinity and ultimate failure to live up to his own imagined ideals.

Among various energy harvesting technologies reverse electrowetting-on-dielectric energy harvesting (REWOD) has been proved to harvest energy from low frequency motion such as many human motion activities (e.g. walking, running, jogging etc.). Voltage rectification and DC-DC boosting of low magnitude AC voltage from REWOD can be used to reliably self-power the wearable sensors. In this work, a commercial component-based rectifier and DC-DC converter is designed and experimentally verified, for further miniaturization standard 180 nm CMOS process is used to design the rectifier and the DC-DC boost converter.This work also includes the MATLAB based model for REWOD energy harvester for various REWOD models. In REWOD energy harvesting, a mechanical input during the motion causes the electrolyte placed in between two dissimilar electrodes to squeeze back and forth thereby periodically changing the effective interfacial area, hence generating alternating current. The alternating current is given to the rectifier design. There is no realistic model that has been developed yet for this technique. Thereby, a MATLAB based REWOD model is developed for the realistic simulation of the REWOD phenomenon. In the work, a comparison of different REWOD models such as planar surface, rough surface and porous models are performed demonstrating the variations in capacitance, current …

The minority stress model provides context to understand the mechanisms by which prejudicial experiences contribute to the disproportionate prevalence of adverse physical and mental health outcomes among LGBT people. The transactional model of stress and coping explains the appraisal processes through which people identify stigma-related stimuli as threatening and how they assess available coping resources to counteract these threats. The Connor-Davidson Resilience Scale (CD-RISC) and the Perceived Stress Scale (PSS) were used in this study to measure resilience and stress in a sample of 99 lesbian and gay older adults. Women reported statistically significantly higher levels of resilience and lower levels of perceived stress compared to older gay men. An analysis of covariance (ANCOVA) revealed statistically significant main effects for gender (Cohen's d = .51; ηp2 = .056; F(1,98) = 5.488, p = .021) while controlling for perceived stress (Cohen's d = 1.62; ηp2 = .375; F(1,98) = 55.840, p < .001). An interaction effect between gender and perceived stress was also statistically significant (Cohen's d = .72; ηp2 = .115; F(1,98) = 12.40, p < .001) indicating that the negative relationship between stress and resilience is stronger for older gay men. Clinical implications and relevance to future research are …

Vegetative health was measured both before and after Hurricane Harvey using remotely sensed vegetation indices on the coastal marshland surrounding Galveston Island's West Bay. Data were recorded on a monthly basis following the hurricane from September of 2005 until September of 2019 in order to document the vegetation response to this significant disturbance event. Both initial impact and recovery were found to be dependent on a variety of factors, including elevation zone, spatial proximity to the bay, the season during which recovery took place, as well as the amount of time since the hurricane. Slope was also tested as a potential variable using a LiDAR-derived slope raster, and while unable to significantly explain variations in vegetative health immediately following the hurricane, it was able to explain some degree of variability among spatially close data points. Among environmental factors, elevation zone appeared to be the most key in determining the degree of vegetation impact, suggesting that the different plant assemblages that make up different portions of the marsh react differently to the severe flooding that took place during Harvey.

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 …

This thesis looks at how women journalists are now also digital influencers on Instagram. It analyzes the gendered expectations of women journalists that are also included on their professional Instagram accounts.

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.
