Study of Homeless Emergency Discharge Coordination: Understanding Challenges and Success Factors to Collaboration Maturity
Successful service coordination for the homeless depends on the ability of diverse organizations to effectively collaborate. This study utilizes a life-cycle framework to expand on the collaborative governance theory by highlighting the different stages of collaboration that homeless service networks encounter. Activation, collectivity, and institutionalization are three stages used to uncover the unique nature of emergency discharge planning processes. Since collaboration is not a static process and government regulation for emergency discharge plans were recently enacted in 2012, collaborative networks encounter challenges and success factors at different stages. A qualitative case-study approach of organizational leaders in homeless service networks in Texas (Dallas, Ft. Worth and Houston) examines stages of collaboration. Results show common success and challenge factors identified among the three networks, but the factors take on different forms in relation to where the networks are at in the coordination stages. Practitioners can use the findings from this study as a guide to set up benchmarks and measurable objectives to identify strengths and weaknesses in their coordination processes.

A Study of Selected Pedagogical Aspects of Two Intercultural Pieces for Late Intermediate and Early Advanced Students: "Variations sur un thème populaire coréen" by Sung-Ki Kim and "Six Pieces for Piano ‘Nori'" by Chung-Sock Kim
Access:
Use of this item is restricted to the UNT Community
I contend that young students should be introduced to intercultural contemporary music, as this exposure brings benefits to their artistic development and fosters appreciation of other cultures. Variations sur un thème populaire coréen by Sung-Ki Kim (b. 1954) and Six Pieces for Piano ‘Nori' by Chung-Sock Kim (b. 1940) are effective pedagogical works that fit perfectly into the intercultural mold mentioned above, and both are suitable for late intermediate or early advanced level students. A detailed comparison of these two works can help instructors understand the ways by which these composers incorporate Korean folk materials and blend them with Western contemporary techniques. An analysis of Sung-Ki Kim's Variations sur un theme populaire coréen and Chung-Sock Kim's Six Pieces for Piano ‘Nori' can be divided into three categories: harmony, rhythm, and performance-related aspects. By analyzing these two pieces, these study illustrates in greater depth their intercultural aspects, showing the way by which both composers merged traditional Korean folk idioms through the inclusion of traditional Korean rhythms, and the imitation of sounds of several traditional Korean instruments with Western contemporary technique such as non-traditional sounds and use of sostenuto pedal. Finally, this study provides some practicing suggestions and listing exercise on how …

Synthesis and Characterization of β-Functionalized π-Extended Porphyrins
Porphyrins with extended π-electronic networks are promising candidates for a wide range of applications from medicine to nanotechnology owing to their unique optical and electronic properties. This dissertation is focused on synthesis, characterization and application of β-functionalized π-extended porphyrins. This dissertation is comprised of seven chapters. Chapter 1 focuses on the importance and objective of this work. Chapter 2 gives brief introduction to porphyrins and π-extended porphyrins. In chapter 3, a class of β-functionalized linear push-pull zinc dibenzoporphyrins YH1-YH3 were designed, synthesized, and utilized as light harvesters for DSSCs. In chapter 4, in order to further enhance the photovoltaic performance of β-functionalized benzoporphyrin dyes based DSSCs, a new class of push-pull dibenzoporphyrins YH4-YH7 bearing the phenylethynyl bridge was designed, synthesized and utilized as light harvesters for DSSCs. In chapter 5, in order to solve the photodegradation problem associated with YH7, a new series of push-pull dibenzoporphyrins YH8-YH10 bearing different diarylamino push groups was designed and synthesized. This class of push-pull porphyrins shows improved photostability and enhanced DSSC performance. In chapter 6, a new pentacene-fused diporphyrin with high stability and solubility was prepared and characterized. Chapter 7 includes the summary of this dissertation and describes possible future work.

Tchaikovsky's Piano Concerto No. 1 In B-Flat Minor, Op. 23: A Newly Arranged Edition of the Orchestral Reduction
Access:
Use of this item is restricted to the UNT Community
As it stands, only one arrangement of Tchaikovsky's Piano Concerto No. 1, Op. 23 orchestral reduction exists, which is by Tchaikovsky himself. A number of critical editions of the piece exist, but none of them cover the subject of the material within the orchestral reduction. Tchaikovsky wrote the reduction from a compositional rather than a pianistic perspective, thus some passages present awkward technical challenges. The purpose of this dissertation is ultimately to contribute to the repertoire of accompanists by producing a new edition of Tchaikovsky's Piano Concerto No. 1. I created my arrangement through a process of practical trial and error as well as observing the strategies used by other arrangers of orchestral reductions. Through a series of carefully selected omissions, note rearrangements, visual adjustments, and editorial changes, I simplified the reduction as a whole. I sought to improve the readability of the music by reducing accidentals as much as possible and also incorporating small-print cues into the main staves. Each minor adjustment or major revision contributes cumulatively to the ease of execution of the accompanimental part as a whole. Although Tchaikovsky's reduction is authentic and authoritative, a newly revised and simplified version would be useful for collaborative pianists. Thus, …

The Teaching of 21st Century Skills through Project-Based Learning and Professional Development for Career and Technical Education
The purpose of this non-experimental, quantitative study is to investigate the relationship between the use of project-based learning (PBL) by secondary business teachers and time spent in professional development of secondary business teachers for the teaching of 21st century skills. The four identified 21st century skills that will be researched include: (1) critical thinking, (2) collaboration, (3) communication, (4) creativity and innovation. A sample of 316 secondary business teachers were surveyed about their classroom practice and reflection of teaching 21st century skills. This study used a modified version of the 21st Century Teaching and Learning Survey. Survey results were analyzed for relationships using correlational and regression analysis. Business teachers reported a statistically strong relationship between the use of PBL and the teaching of 21st century skills. A statistically significant relationship between time spent in professional development and the teaching of 21st century skills was not found. Regression results indicated that the use of PBL had an impact on the teaching of 21st century skills. This research guides teachers, school administrators, and CTE directors at the state and district level towards the creation of professional development and implementation strategies when applying PBL methods in career and technical education settings.

As the Need Presents Itself: Social Identity Theory and Signaling in Online Crowdfunding Campaigns
As social interactions increasingly become exclusively online, there is a need for research on the role of identity and social identity in online platforms. Drawing on Symbolic Interactionist approaches to identity, namely Social Identity Theory and Identity Theory, as well as Signaling Theory, this study argues that actors will selectively use religious language to signal their credentials to an audience for the purpose of garnering prosocial behavior in the form of donations to their fundraising campaign. Using latent semantic analysis topic models to analyze the self-presentations of crowdsourcing campaigners on GoFundMe.com, this study found evidence for the presence of signaling to a religious identity online as well as a significant difference in the presentation of need for campaigns originating in areas with high reported religiosity compared to campaigns from areas of low religiosity. In comparison to other campaigns, campaigners engaging in religious signaling were significantly increasing their donations. I suggest that strategically chosen religious topics in online crowdfunding is an example of low-cost identity signaling and provides insight into how signaling happens online and the potential outcomes resulting from this cultural work.

Transgenerational Responses to Environmental Stressors in Vertebrates: From Organisms to Molecules
Genomic modifications occur slowly across generations, whereas short-term epigenetic transgenerational inheritance of adaptive phenotypes may be immediately beneficial to large numbers of individuals, acting as a bridge for survival when adverse environments occur. In this study we used dietary exposure to crude oil as an example of an environmental stressor to assess its effects from the molecular to the organismal levels in piscine and avian animal models. In addition, we assessed the role of the parental exposures on their offspring F1 generation. The research developed in this dissertation has contributed to several areas of investigation including molecular biology, animal physiology, and evolutionary biology. The quantitative information from these studies may be utilized to supplement information regarding the proximate and ultimate effects of environmental stressors on fish and bird populations. Furthermore, this information may be used as additional support for understanding the conservation of the responses from the molecular to the whole organismal levels across the vertebrate taxa, as well as their implications for population survival and maintenance. Additionally, the zebrafish (Danio rerio), the Siamese fighting fish (Betta splendens) and the king quail (Coturnix chinensis) have proven to be excellent models to start building a strong basis for understanding the effects …

Uncovering Fanny Hensel's "Das Jahr": Creating an Urtext Edition that Addresses Selected Technical and Interpretive Issues through Added Fingerings and Pedal Markings
Access:
Use of this item is restricted to the UNT Community
Das Jahr is considered Fanny Hensel's most impressive accomplishment of piano solo work. However, the only modern edition that is extant includes many additional editorial markings. By further analyzing the sections that are technically challenging or musically demanding from an interpretive standpoint, pianists wishing to perform the work will have to find workable fingerings and pedal markings to learn this piano cycle. For this reason, this dissertation will not only provide readers with an original text of Das Jahr, but also assist pianists in finding practical solutions that can help them to interpret this distinctive work successfully on the modern piano.

Understanding Factors that Contribute to Career Commitment in New Student Affairs Professionals
Early career attrition in student affairs is a topic of interest for hiring and supervising managers, graduate preparation programs, as well as new professionals. Contributions to the growing body of research on the topic potentially informs bets practices in curriculum development, hiring, onboarding, and professional development for new student affairs employees. This study involved 352 new student affairs professionals in the field's largest professional association. With Rhodes and Doering's integrated model of career change as a framework, the research study was designed to identify individual and environmental factors influencing new student affairs professionals' person-environment fit and, subsequently, career commitment. The result was an eight-factor structural equation model that included graduate curriculum, pay satisfaction, mentoring, student interaction, connection to institutional mission/vision, collegiality, and person-environment fit as independent variables, and career commitment as the dependent variable. The study suggests that these eight variables, to varying degrees, indirectly and directly influence career commitment in new student affairs professionals.

When Does Race Matter in Music Education?: An Exploration of Race, Racial Hegemony, and Predominantly Latinx Secondary Music Programs through the Theory of Racial Formation
Latinx students are underrepresented among high school music students in the United States, nationally. However, localized demographics in some parts of the country reveal secondary music programs that are comprised nearly entirely of Latinx students. Still, the experiences of such a large and racially marginalized population as Latinx students remain under-researched in the field of music education. To explore how Latinx racial identity may inform the experiences of Latinx music students and their music teachers, I conducted a post-qualitative study of students and teachers in music classes at large secondary schools in which the Latinx population is 95 percent or more. Data were collected through in-depth, semi-structured interviews with music students and their teachers. To guide my thinking on the role of race in the lives of the participants, I incorporated Omi and Winant's (2015) theory of racial formation throughout the data analysis. Overall findings indicated that race informs much of the experiences of the participants in varying, sometimes subtle ways. Through racism, racial resistance, the formation of racial identity, and the incorporation of both colorblind ideology and race consciousness, the participants provided nuance as to how we may regard the role and significance of race in music education. Implications …

William Gillock's Contributions to Piano Pedagogy: A Comparison of Three Works of Gillock with Selected Stylistic Models from the Baroque, Classical, and Romantic Repertoire
Access:
Use of this item is restricted to the UNT Community
William Gillock, a 20th-century American composer and pedagogue, composed numerous works in the styles of different periods for early intermediate-level piano students. The purpose of this dissertation is to introduce Gillock's pieces to teachers of early intermediate students and illustrate how they can be used as a bridge to the study of similar music from Baroque, Classical, and Romantic periods. Gillock's Little Suite in Baroque Style is compared with Handel's Suite in E Major, HWV 430; his Accent on Analytical Sonatinas (Classical) is compared with Clementi's Piano Sonatinas, Op. 36, No. 3, 5, 6; and his Lyric Preludes in Romantic Style (Romantic) is compared with Chopin's 24 Preludes, Op. 28, No. 3, 6, 9, 16, 18, and 24. Each work is examined to reveal its compositional and technical elements along with pedagogical concepts.

Women's Access to School Superintendency Roles
Men continue to outnumber women in public school superintendent roles by a 4:1 ratio. However, women outnumber men by a 4:1 ratio in teaching roles in public school districts. In addition, more women than men hold superintendent certificates and educational doctorates. Due to this puzzling discrepancy, it is important to understand possible factors in the form of gendered barriers to access that could lead to the unequal representation of women in superintendent positions. In this study, I examined how these barriers manifested in the experiences of female superintendents participating in the study, how they influenced the hiring experiences of these participants, and how they impacted these female leaders throughout their careers. With this study, I investigated barriers associated with holding mechanisms, gendered norms, and gendered filters that may limit women's access to superintendent roles. Women's experiences of the origins and effects of gender normative perceptions and hiring practices have potential for contributing to the study of gender equity in the field of education and beyond. Findings could provide implications for increasing women's opportunities to serve beyond central office positions in public school districts. Possibilities exist for identifying practices in organizations that have hired women to serve at the highest level …

Your Blues Ain't Like Mine: Voices from the Other Side of the Color Line
Access:
Use of this item is restricted to the UNT Community
This dissertation examines intra-racial colorism in works by writers who began their careers during the Harlem Renaissance, but whose writings span almost a century. In these writings, colorism; which can be defined as a bias directed toward an individual that is based on skin tone, is portrayed an intra-racial practice that results from the internalization of racist ideals. The practice relies on a hierarchy that most often privileges those closest to the color line. However, these depictions also show that the preponderance of skin tones can sometimes determine who is targeted. For the purposes of this study it is called reverse colorism when the bias is directed by individuals darker in skin tone toward those who are lighter. Consequently, the careful descriptions of the shades and hues of black characters becomes more than aesthetics and can be seen as a coded reference to experiential differences. While Alain Locke hailed the start of the Harlem Renaissance to signal the rise of The New Negro, the writings featured by female writers in this dissertation advance a less optimistic reality for women, who had to contend with both inter- and intra-racial bias because of their skin tone. Colorism is identified as a particularly …
