The Effectiveness of Peer Mentoring with High School Student Mentors and Child Mentees
This randomized, controlled study examined the effectiveness of two mentoring programs, child mentor relationship training (CMRT) and peer assistance and leadership (PAL®), on high school mentor empathic behaviors and child mentee behavior problems. Participants were 60 young, at-risk students (61.7% male; 38.3% Hispanic/Latino/a, 31.7% Caucasian, 21.7% African American, 8.3% biracial) and 30 high school students (53.3% male; 66.7% Caucasian, 26.7% Hispanic/Latino/a, 0.03% African American, 0.03% Asian). Mentors and mentees were randomly assigned to CMRT or PAL®, which was treatment as usual in the participating school district. Results from 2 (group) by 2 (time) repeated measures ANOVAs indicated compared to the PAL® treatment group over time, mentors in the CMRT group demonstrated statistically significant improvement in empathic behaviors with a large treatment effect, as rated by independent observers. Analysis revealed a moderate treatment effect with CMRT group mentee behavior problems, but the difference was not statistically significant between treatment groups over time. Further analysis revealed the CMRT group demonstrated statistically significant reductions in behavior problems from pre- to post-test with a very large treatment effect. Overall, findings support CMRT as a promising school-based intervention for at-risk young children that potentially increases school counselor efficiency.

Phylogenetic and Functional Characterization of Cotton (Gossypium hirsutum) CENTRORADIALIS/TERMINAL FLOWER1/SELF-PRUNING Genes
Plant architecture is an important agronomic trait driven by meristematic activities. Indeterminate meristems set repeating phytomers while determinate meristems produce terminal structures. The centroradialis/terminal flower1/self pruning (CETS) gene family modulates architecture by controlling determinate and indeterminate growth. Cotton (G. hirsutum) is naturally a photoperiodic perennial cultivated as a day-neutral annual. Management of this fiber crop is complicated by continued vegetative growth and asynchronous fruit set. Here, cotton CETS genes are phylogenetically and functionally characterized. We identified eight CETS genes in diploid cotton (G. raimondii and G. arboreum) and sixteen in tetraploid G. hirsutum that grouped within the three generally accepted CETS clades: flowering locus T (FT)-like, terminal flower1/self pruning (TFL1/SP)-like, and mother of FT and TFL1 (MFT)-like. Over-expression of single flower truss (GhSFT), the ortholog to Arabidopsis FT, accelerates the onset of flowering in Arabidopsis Col-0. In mutant rescue analysis, this gene driven by its native promoter rescues the ft-10 late flowering phenotype. GhSFT upstream sequence was used to drive expression of the uidA reporter gene. As anticipated, GUS accumulated in the vasculature of Arabidopsis leaves. Cotton has five TFL1-like genes, all of which delay flowering when ectopically expressed in Arabidopsis; the strongest phenotypes fail to produce functional flowers. Three …

Artscapes: Community Perceptions of City Beautification through Murals in Denton, Texas
Keep Denton Beautiful (KDB) is inspired by Keep America Beautiful's model of community engagement to create a clean, beautiful, and vibrant city. The community mural initiative, Artscapes, aims to enliven public spaces, abate graffiti, and inspire community members to keep Denton, Texas, clean and beautiful. The goals of this research project are to understand the impact of Artscapes initiative, community perceptions of public art, and find ways KDB can better align future mural projects with the needs and desires of community members. By talking to artists that have worked with KDB, members of the mural art committee, and community members from the neighborhoods that have existing murals, this research provides input from these three populations to continue creating public art for the Denton community. I discuss the context of my work through Lefebvre's concept of "Right to the City," Rafael Schacter's opposition between sanctioned and non-sanctioned murals, Bourdieu's concept of symbolic and social capital, and David Harvey's work on neoliberalism and the entrepreneurial city.

Considerations for Global Development and Impact using Haiti as a Case Study
As the world becomes more connected, issues surrounding sustainable development are coming to the fore of global discussions. This is exemplified in strategies such as the United Nation's Sustainable Development Goals (SDGs), released in 2015, which created a framework for global development that defines specific goals for issues like poverty, climate change, and social justice. To complement the analysis that went into defining the SDGs, capital allocations around the world are becoming more impact focused so that the paradigm of development is shifting from donations to impact investments. The push for impact, however, has led to a homogenization of global challenges like reproductive health and poverty. This, in turn, has led to a standardization of information resulting in agencies designing interventions based on data and information that is misguided because of incorrect assumptions about a specific context. This paper explores how the decision-making mechanisms of global development agencies and investors could apply more anthropological processes to mitigate negative impact. As the development sector becomes more and more standardized, anthropologists can act as translators between affected communities and the institutions deciding how best to help them.

The Impact of True Fit® Technology on Millennial Consumer Confidence and Satisfaction in their Online Clothing Purchase
This study examines the use of True Fit® technology by millennial consumers and its impact on consumer confidence and satisfaction with respect to online sizing. In the apparel industry, there is a lack of size standards among retailers, and as a result consumers will encounter frequent size variations in their clothing size. Difference sizing technology has been developed to address the sizing issue. One is True Fit® which unlike other sizing technologies, uses mathematical algorithms to compile large amounts of data from designers. The purpose of this study was to analyze consumer confidence and satisfaction after True Fit® has been used to make a sizing decision while online shopping. The technology acceptance model (TAM) was used as the basis for the theoretical framework for this study. TAM explores how current advances in technology are influencing consumers' behaviors and attitudes. The variables studies included perceived ease of use, perceived usefulness, attitude, intent to use True Fit®, confidence and satisfaction. The methodology used in the study is a quantitative method consisting of an online survey and a True Fit® task, where consumers were exposed to True Fit® prior to answering questions about the use of sizing technology. The results of the study …

Using Concurrent Schedules of Reinforcement to Decrease Behavior
We manipulated delay and magnitude of reinforcers in two concurrent schedules of reinforcement to decrease a prevalent behavior while increasing another behavior already in the participant's repertoire. The first experiment manipulated delay, implementing a five second delay between the behavior and delivery of reinforcement for a behavior targeted for decrease while no delay was implemented after the behavior targeted for increase. The second experiment manipulated magnitude, providing one piece of food for the behavior targeted for decrease while two pieces of food were provided for the behavior targeted for increase. The experiments used an ABAB reversal design. Results suggest that behavior can be decreased without the use of extinction when contingencies favor the desirable behavior.

Impact of Relational Incongruity on Customer Ownership and Sales Outcome Performance: A Resource-Advantage Theory Approach
There exists heightened research attention afforded to the pivotal demands - both internal and external - that exist within the salesperson role set. Unprecedented pressures on salespersons to acquire, retain, and build enduring customer relationships to enhance the firm's bottom-line performance coincides with increasing complexities within the work environment. This relevant and timely research introduces an original construct derived from the long-standing attention afforded to relationship selling, relational incongruity that exists within the buyer-seller exchange. Relational incongruity, defined, is the relational tension spawned between the salesperson, the customer, and the firm when situational psychological incongruity exists within the buyer-seller exchange itself. Framed in resource-advantage theory, this research investigates divergent demands and the increasing complexity of sales relationships through the lens of relational incongruity. A research program based on minimizing relational incongruity will augment the sales management and B2B literature by looking at how he salesperson and the customer build strong relationships as well as the antecedents that can undermine these relationships by generating realtional incongruity.

Effects of HALSs and Nano-ZnO Worked as UV Stabilizers of Polypropylene
This work reports the outdoor weathering performance of ultraviolet (UV)-stabilized polypropylene (PP) products (using PP resins from Encore Wire). Different hindered amine light stabilizers (HALSs) and nano-ZnO were used to stabilize PP-film-based formulations that were exposed under UV light for 6 weeks simulating for in harsh outdoor weather of Dallas, Texas, USA in 2016. Characterization of the exposed PP film products was done in terms of mechanical and friction spectroscopic properties. The PP film formulations were divided into 15 categories based on the type of HALS and nano-ZnO incorporated. This was done to derive meaningful comparison of the various film formulations. Following exposure under UV light, the lifetimes of certain formulations were determined. On the basis of the mechanical and friction properties, it was determined that generally, the HALS or nano-ZnO stabilized PP film give better properties and if those two kinds of UV stabilizers can work together.

Core-Shell Based Metamaterials: Fabrication Protocol and Optical Properties
The objective of this study is to examine core-shell type plasmonic metamaterials aimed at the development of materials with unique electromagnetic properties. The building blocks of metamaterials under study consist of gold as a metal component, and silica and precipitated calcium carbonate (PCC) as the dielectric media. The results of this study demonstrate important applications of the core-shells including scattering suppression, airborne obscurants made of fractal gold shells, photomodification of the fractal structure providing windows of transparency, and plasmonics core-shell with a gain shell as an active device. Plasmonic resonances of the metallic shells depend on their nanostructure and geometry of the core, which can be optimized for the broadband extinction. Significant extinction from the visible to mid-infrared makes fractal shells very attractive as bandpass filters and aerosolized obscurants. In contrast to the planar fractal films, where the absorption and reflection equally contribute to the extinction, the shells' extinction is caused mainly by the absorption. This work shows that the Mie scattering resonance of a silica core with 780 nm diameter at 560 nm is suppressed by 75% and only partially substituted by the absorption in the shell so that the total transmission is noticeably increased. Effective medium theory supports …

The Generation of Recombinant Zea mays Spastin and Katanin Proteins for In Vitro Analysis
Plant microtubules play essential roles in cell processes such as cell division, cell elongation, and organelle organization. Microtubules are arranged in highly dynamic and ordered arrays, but unlike animal cells, plant cells lack centrosomes. Therefore, microtubule nucleation and organization are governed by microtubule-associated proteins, including a microtubule-severing protein, katanin. Mutant analysis and in vitro characterization has shown that the highly conserved katanin is needed for the organization of the microtubule arrays in Arabidopsis and rice as well as in a variety of animal models. Katanin is a protein complex that is part of the AAA+ family of ATPases. Katanin is composed of two subunits, katanin-p60, a catalytic subunit and katanin-p80, a regulatory subunit. Spastin is another MT-severing protein that was identified on the basis of its homology to katanin. In animal cells, spastin is also needed for microtubule organization, but its functionality has not yet been investigated in plants. To initiate an exploration of the function of katanin-p60 and spastin in Zea mays, my research goal was to generate tools for the expression and purification of maize katanin-p60 and spastin proteins in vitro. Plasmids that express katanin-p60 and spastin with N-terminal GST tags were designed and constructed via In-Fusion® cloning …

Child-Centered Play Therapy (CCPT) with Latina/o Children Exhibiting School Behavior Problems: Comparative Effects of Delivery by Spanish-Speaking and English-Speaking Counselors
The shortage of bilingual counselors is one barrier to young Latina/o children receiving mental health services. Child-centered play therapy (CCPT) is a developmentally responsive intervention based on the premise that play is children's natural means of communication across cultures. This randomized controlled study examined the effects of CCPT with young Spanish-speaking Latina/o children exhibiting clinical levels of school behavior problems. Participants were 57 pre-K to kindergarten Latina/o children (72% male; mean age = 4.0) randomly assigned to three treatment groups: CCPT with Spanish-speaking, bilingual counselors; CCPT with English-speaking, monolingual counselors; or active control (bilingual mentoring). Monolingual counselors participated in cultural competency training and supervision with bilingual counselors and supervisors. According to independent observers and teachers blinded to children's group assignment, both the bilingual CCPT group and the monolingual CCPT group demonstrated moderate treatment effects over bilingual mentoring, yet between-group differences were not statistically significant. Analysis of within-group change over time indicated that children in both CCPT interventions demonstrated statistically significant improvement, while the mentoring group did not. The percentage of children in each treatment group who improved from clinical to normal behavioral functioning suggests the clinical significance of the findings: 80% bilingual CCPT, 70% monolingual CCPT, 15% bilingual mentoring. Overall, …

Human-Machine Interface Using Facial Gesture Recognition
This Master thesis proposes a human-computer interface for individual with limited hand movements that incorporate the use of facial gesture as a means of communication. The system recognizes faces and extracts facial gestures to map them into Morse code that would be translated in English in real time. The system is implemented on a MACBOOK computer using Python software, OpenCV library, and Dlib library. The system is tested by 6 students. Five of the testers were not familiar with Morse code. They performed the experiments in an average of 90 seconds. One of the tester was familiar with Morse code and performed the experiment in 53 seconds. It is concluded that errors occurred due to variations in features of the testers, lighting conditions, and unfamiliarity with the system. Implementing an auto correction and auto prediction system will decrease typing time considerably and make the system more robust.

Exploring the Process of Developing a Glocally Focused Art Curriculum for Two Communities
The world is becoming progressively interconnected through technology, politics, culture, economics, and education. As educators we strive to provide instruction that prepares students to become active members of both their local and global communities. This dissertation presents one possible avenue for engaging students with art and multifaceted ideas about culture, community, and politics as it explores the possibilities for creating a community-based, art education curriculum that seeks a merger of global and local, or "glocal" thinking. Through curriculum action research, I explored the process of writing site-specific curriculum that focuses on publicly available, local works of art and encourages a connection between global experiences and local application. I have completed this research for two communities, one in Ohio and one in Texas, and investigated the similarities and differences that exist in the process and resulting curriculum for each location. Through textual analysis, interviews, curriculum writing, and personal reflections, I identified five essential components of a community-based, glocal art education curriculum: flexibility, authenticity, connectedness, glocal understandings, and publicly available art. Additionally, I developed a template for writing glocally focused, community-based art education curriculum and produced completed curricular units for each of the communities. Finally, I have made suggestions for the future …

When Race Matters: The Influence of Race on Case Clearances in Capital vs. Non-Capital Homicides in Texas
Texas leads the nation in the number of executions carried out since capital punishment was reinstated in 1976. Race was a key factor in the 1972 moratorium, and though the Supreme Court allowed for its return under new statutes, race continues to plague the capital punishment legal system. In this study, I examine the influence of race on case clearances in capital and non-capital homicides in Texas, using the extra-legal and non-discretionary theories from existing clearance literature. I find that race influences the probability of cases being cleared in non-capital cases but has no statistically significant effect in clearing capital cases.

Child-Centered Play Therapy with Children Affected by Adverse Childhood Experiences: A Single Case Design
Child centered play therapy (CCPT) is a therapeutic intervention that provides the environment for children to work through and heal from difficult experiences through expression of play and therapeutic relationship. It has been demonstrated effective with multiple types of disruptive behaviors. I conducted single-case research to explore CCPT's influence on children who had four or more adverse childhood experiences (ACEs) and provided analysis of data collected from one assessment administered weekly and one assessment at pre-, mid-, and post-intervention: the Strength and Difficulties Questionnaire and the Trauma Symptoms Checklist for Young Children. The two participants (one 8-year-old White American male and one 9-year-old White American female) demonstrated significant improvement in total difficulties and prosocial behaviors. The study revealed potential therapeutic benefits for utilizing CCPT with children who had four or more ACEs. Encompassed in discussion of study results are implications for practice, suggestions for future research, and limitations.

Mediational Pathways between High School Extracurricular Participation and Young Adult Educational Attainment: A Structural Equation Analysis
Little is known about the mechanisms by which extracurricular participation in high school influences educational attainment in young adulthood. Also limited is an understanding of the different types of extracurricular participation and how various activities may manifest within the relationship. The purpose of this study was to examine the link between high school extracurricular participation and educational attainment, with social capital, parental expectations, and academic achievement presented as mediators. Additionally, the present study will explore socioeconomic differences in the proposed relationships. The sample consisted of 5,239 ninth through twelfth graders from the National Longitudinal Study of Adolescent Health (Add Health). Structural equation modeling (SEM) and multiple-group SEM were used to test pathways. Extracurricular participation was categorized into sports participation, non-sport participation, mixed participation (including both sport and non-sport), and no participation. Social capital, a latent factor, was measured by the latent variables of family and school capital. Various indicators of family closeness and inclusion of school culture from survey items operationalize social capital. Parental expectations, another latent factor, was measured by one survey indicator using the question of how disappointed would your resident father and mother be if you did not graduate from college. Academic achievement was measured by grade …

Who is Really in Charge Here: An Exploration of the Formation and Empowerment of Opinion Leaders in a Reddit Gaming Community
In an attempt to shed light on the further sophistication of opinion leadership in online communities, this study examined the forces and structures that affect their formation in the League of Legends subreddit. By investigating what users thought about the various types of individuals with which the communicate, the researcher hoped to begin to understand and record how those forces work bother on this particular subreddit and in mass media beyond. Opinion leadership continues to be an integral force in deciding what information is consumed by a public and under what frames and agendas it is contextualized. If researchers can operationalize formal definitions for the influences and structures that occur online, they can better navigate the deep waters that are global communication on the internet.

Stability of Myosin Subfragment-2 Modulates the Force Produced by Acto-Myosin Interaction of Striated Muscle
Myosin subfragment-2 (S2) is a coiled coil linker between myosin subfragment-1 and light meromyosin (LMM). This dissertation examines whether the myosin S2 coiled coil could regulate the amount of myosin S1 heads available to bind actin thin filaments by modulating the stability of its coiled coil. A stable myosin S2 coiled coil would have less active myosin S1 heads compared to a more flexible myosin S2 coiled coil, thus causing increased force production through acto-myosin interaction. The stability of the myosin S2 coiled coil was modulated by the binding of a natural myosin S2 binding protein, myosin binding protein C (MyBPC), and synthetic myosin S2 binding proteins, stabilizer and destabilizer peptide, to myosin S2. Competitive enzyme linked immunosorbent assay (cELISA) experiments revealed the cross specificity and high binding affinity of the synthetic peptides to the myosin S2 of human cardiac and rabbit skeletal origins. Gravitational force spectroscopy (GFS) was performed to test the stability of myosin S2 coiled coil in the presence of these myosin S2 binding proteins. GFS experiments demonstrated the stabilization of the myosin S2 coiled coil by the binding of MyBPC and stabilizer peptide to myosin S2, while the binding of destabilizer peptide to the same resulted …

Eighteenth-Century French Oboes: A Comparative Study
The oboe, which first came into being in the middle of the seventeenth century in France, underwent a number of changes throughout the following century. French instruments were influenced both by local practices and by the introduction of influences from other parts of Europe. The background of the makers of these instruments as well as the physical properties of the oboes help to illuminate the development of the instrument during this period. The examination of measurements, technical drawings, photographs, and biographical data clarify the development and dissemination of practices in oboe building throughout eighteenth-century France. This clarification provides new insight into a critical period of oboe development which has hitherto not been exclusively addressed.

American Choral Music in Late 19th Century New Haven: The Gounod and New Haven Oratorio Societies
This study examines two of the smaller American choral societies that together existed for just over 30 years, 1888 to 1919: The Gounod and New Haven Oratorio Societies of New Haven, Connecticut. These societies are important because, especially in the case of the New Haven Society, they were closely related to Yale University and the work of Horatio Parker. One must assume from the onset that the two choral groups examined in the following pages did not have the prominence of the many larger New England choral societies. However a more detailed knowledge about the struggles, successes, influence and leadership of two smaller societies illuminates a field of research in the history of American choral music that has been largely ignored.

The Study of English, French, German and Italian Techniques of Singing Related to the Female Adolescent Voice
Throughout the recorded history of vocal development certain characteristics can be traced to nationalistic roots. This work explores the four major schools of singing: English, French, German and Italian and includes a brief history of the pedagogical development and ideas of these schools' development. In addition, specific techniques and their similarities and differences, between each school is explored. Through the use of students as a control group, various characteristics within the four schools are implemented in coaching. The results are noted. The major theme of this work is to outline the major schools of vocal pedagogy and to contrast and compare specific techniques found in each school. Furthermore, regarding the individual student, the positive and negative effects of teaching in a dedicated fashion to one school versus the implementation of proven methods, of various schools, even though they cross nationalistic boundaries, has been the major thrust of this investigation

Response Guided Errorless Learning with Normal Elderly
This study investigates the use of response guidance for errorless learning of a perceptual motor task in normal elderly. It provides normative data for a study with stroke patients using this technique for cognitive rehabilitation. While errorless learning has been shown to be more effective on most tasks than trial and error learning for people with memory impairments, its use with normal individuals has received limited attention. The questions of interest were whether errorless training of the perceptual motor task was more effective for improving and retaining accuracy; and whether both accuracy and response speed were more resistant to the effects of increased cognitive demands. A sample of 43 normal elderly in the United Kingdom, ranging in age from 60 to 77, completed an assessment of intelligence, memory, and attention. They then received training, over two sessions one week apart, to mark the midpoint of Judd Arrows presented on a computer screen using a cross cursor moved by an active force feedback joystick (AFF). During training the errorless group received AFF guidance to the correct midpoint, while the errorful group received none, and both received auditory and visual knowledge of results. There was no AFF during baseline or post test …
