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.

Training Behavior Professionals to Use the Interview-Informed Synthesized Contingency Analysis (IISCA): Extension
The current investigation replicated and extended previous research on training of behavior professionals to implement functional assessment and analysis procedures. Specifically, the study extended procedures described by Metras to train board certified behavior analysts (BCBAs) to administer two components of the Interview Informed Synthesized Contingency Analyses (IISCA) by: (1) conducting the study in the context of a large residential/training facility for adults with ID, (2) including a participant who served as a behavior analyst for a caseload of individuals who lived and received services at the facility, and (3) adjusting the vignettes and interview scripts to reflect the change in context. This current study shows that, following a brief training sequence, the participant was able to accurately administer the open-ended interview and construct a synthesized test and control condition.

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 …

Transient Expression of BABY BOOM, WUSCHEL, and SHOOT MERISTEMLESS from Virus-Based Vectors in Cotton Explants: Can We Accelerate Somatic Embryogenesis to Improve Transformation Efficiency?
Upland cotton (Gossypium hirsutum L.) is the world's most prominent fiber crop. Cotton transformation is labor intensive and time consuming, taking 12 to 18 months for rooted T0 plants. One rate limiting step is the necessary production of somatic embryos. In other recalcitrant species, ectopic expression of three genes were shown to promote somatic embryogenesis: WUSCHEL (WUS), SHOOT MERISTEMLESS (STM), and BABY BOOM (BBM). WUS is responsible for maintaining stem-cell fate in shoot and floral meristems. STM is needed to establish and maintain shoot meristems. STM and WUS have similar functions but work in different pathways; overexpression of both together converts somatic cells to meristematic and embryogenic fate. BBM encodes an AP2/ERF transcription factor that is expressed during embryogenesis and ectopic expression of BBM reprograms vegetative tissues to embryonic growth. In prior studies, these genes were constitutively expressed, and cultures did not progress beyond embryogenesis because the embryogenic signal was not turned off. In our study, we set out to use these genes to increase the efficiency of cotton transformation and decrease the time it takes to regenerate a plant. A disarmed cotton leaf crumple virus (dCLCrV) vector delivers WUS, STM, or BBM into cotton tissue cultures through Agrobacterium tumefaciens …

Twenty-First Century Local Food Farmers in North Texas: An Evaluation of Farming Methods, Best Practices, and Common Struggles
Research with local farmers and local food consumers in the North Texas area which captures a contemporary understanding of the challenges and successes present in North Texas local farm-and-food networks. Through ethnographic research methods, including participant-observation and semi-structured interviews, the network of producers and consumers around several farmers' markets were evaluated to understand where the strengths of local food lie, and where networks need development to promote a more stable local food environment. Texas is newer to the trend of farmers' market development, with the local food system developed to foster community, educate, and promote the advantages of locally sourced goods. This research led to the academic discovery of climate adaptive ecological knowledge and farm commodification strategies; which are tools that farmers may use to build greater defense against threats to a farm's livelihood.

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.

La vía del abandono en los cuentos de Amparo Dávila
Access:
Use of this item is restricted to the UNT Community
Amparo Davila's writing style is characterized by circumventing the boundaries between the real and the fantastic and between the known and the unknown. The author creates a narrative that evokes horror in the reader by mixing the uncanny of the unknown with the reality of the world. This study proposes that the sinister in Davila's stories are created by abandonment. This abandonment is the peremptory element of Davilian narrative and can be seen and examined throughout the author's literary work. The abandonment wields a mechanism of loneliness, madness, hopelessness and chaos that eventually provokes the sinister. The element of abandonment disturbs the main character of the story and makes him fall into an abyss from which he or she cannot escape. This abandonment is not always obvious, since most of the time the abandonment is veil by a halo of gothic and fantastic elements. The present thesis has the task of breaking down the different types of abandonment that are presented throughout this narrative, its sinister function and the theoretical and historical interpretation of the various abandonments both personal and collective that Amparo Davila presents. The route of abandonment proposed in this thesis is explained in the following three stories: …

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 in the Foreign Service: A Case Study of Margaret Parx Hays, 1942-1964
This project seeks to include the historical significance of women in the Foreign Service and subsequently the United States Department of State between 1942 and 1964. Using the life and experience of Margaret Parx Hays, one of fewer than three hundred female foreign service officers before 1960, this study explores the importance of examining women at the "ground level." This narrative examines the life of Hays at several different duty stations and her experience navigating a male-dominant workplace congruent to the political and diplomatic missions of each stations. Hays was stationed in Buenos Aires, Argentina (1942-1945); Bogota, Columbia (1945-1947); Rio de Janeiro, Brazil (1948-1950); Washington D.C., U.S. (1951-1954; 1959-1962); Manila, Philippines (1954-1956); Mexico City, Mexico (1956-1958); and Hong Kong, China (1962-1964). Throughout the deployment at each station, Hays was confronted with major political events in her duty station's history or in the intersection of American foreign and domestic policy. Through the use of Hays's archived collection of personal papers, including letters and newspapers, this thesis presents a more representative story about women and about the Department of State as a larger whole than previous scholarship that has ignored how gender affected diplomatic history.

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 …
