A Grounded Theory of Music Teacher Large Scale Conference Professional Development Implementation: Processes of Convergence
The purpose of this study was to understand the process of music teacher large-scale conference professional development (PD) implementation (i.e., the integration of conference-derived learnings into classroom practice). The context of this investigation was two national music conferences, the Midwest Clinic and the National Association for Music Education National In-Service Conference, and one state music conference, the Texas Music Educators Association Clinic/Convention. Using purposive maximum variation sampling, active music teachers (n = 32) who each attended one of these conferences were recruited. Data collection occurred in a series of three participant interview phases, staggered according to which conference participants attended and when each conference was held. Twenty-eight participants were interviewed twice, and four participants were interviewed once, yielding a total of 60 interview transcripts, which were then openly, axially, and selectively coded in accordance to grounded theory method. The principal finding, the cycle of music teacher large scale conference professional development implementation (C-MTPDI), revealed an implementation process in three phases. First, the consideration phase (before/during conference) entailed needs assessment, direct engagement, change articulation, and, for some participants, deterrent factors/contingencies. Second, the realization phase (immediate post-conference) included translation, integration, and recalibration. Third, and finally, the decision phase (3-5 weeks post-conference) included …

Hausdorff Dimension of Shrinking-Target Sets Under Non-Autonomous Systems
For a dynamical system on a metric space a shrinking-target set consists of those points whose orbit hit a given ball of shrinking radius infinitely often. Historically such sets originate in Diophantine approximation, in which case they describe the set of well-approximable numbers. One aspect of such sets that is often studied is their Hausdorff dimension. We will show that an analogue of Bowen's dimension formula holds for such sets when they are generated by conformal non-autonomous iterated function systems satisfying some natural assumptions.

Health Disparities among Sexual Minorities: Trends of Health Care and Prevalence of Disease in LGB Individuals
The primary focus of the current study was to identify health disparities between sexual minority subgroups by examining differences of health indicators in lesbians, gay men, and bisexual individuals, and compare these to their heterosexual counterparts. Data was drawn from the National Health and Nutrition Examination Survey (NHANES), and variables examined in sexual minorities were related to health care access and utilization, risky health behaviors, and overall disease prevalence and outcomes. Findings suggest there are still some current health disparities in terms of insurance coverage, access to medical care, substance use, and prevalence of certain health conditions. However, a trend analysis conducted to examine three NHANES panels, suggests a mild improvement in some of these areas. Further findings, discussion, limitations of the study, current implications, and future directions are addressed.

Heat Transfer in Low Dimensional Materials Characterized by Micro/Nanoscae Thermometry
In this study, the thermal properties of low dimensional materials such as graphene and boron nitride nanotube were investigated. As one of important heat transfer characteristics, interfacial thermal resistance (ITR) between graphene and Cu film was estimated by both experiment and simulation. In order to characterize ITR, the micropipette sensing technique was utilized to measure the temperature profile of suspended and supported graphene on Cu substrate that is subjected to continuous wave laser as a point source heating. By measuring the temperature of suspended graphene, the intrinsic thermal conductivity of suspended graphene was measured and it was used for estimating interfacial thermal resistance between graphene and Cu film. For simulation, a finite element method and a multiparameter fitting technique were employed to find the best fitting parameters. A temperature profile on a supported graphene on Cu was extracted by a finite element method using COMSOL Multiphysics. Then, a multiparameter fitting method using MATLAB software was used to find the best fitting parameters and ITR by comparing experimentally measured temperature profile with simulation one. In order to understand thermal transport between graphene and Cu substrate with different interface distances, the phonon density of states at the interface between graphene and Cu …

"Her Name Was"
Her Name Was is an examination of the oppression of transgender people in a society that is built on the nominalization of cisgender people, those who gender matchers their sex assigned at birth, and how this oppression lends itself to violence. In the summer of 2015, the body of Shade Schuler, an African American transgender woman, was found in a field outside of Dallas, Texas. Ms. Shade is part of an alarming epidemic of escalating levels of targeted violence against the transgender community. This documentary pulls back the curtain as it captures the feelings and struggles of the transgender community as they attempt to navigate and survive in a cis dominating society.

High-Energy, Long-Lived Charge-Separated States via Molecular Engineering of Triplet State Donor-Acceptor Systems
Molecular engineering of donor-acceptor dyads and multimodular systems to control the yield and lifetime of charge separation is one of the key goals of artificial photosynthesis for harvesting sustainably solar energy. The design of the donor-acceptor systems mimic a part of green plants and bacterial photosynthetic processes. The photochemical events in natural photosynthesis involve the capturing and funneling of solar energy by a group of well-organized chromophores referred to as an ‘antenna' system causing an electron transfer into the ‘reaction center,' where an electron transfer processes occur resulting a long-lived charge separated state. Over the last two to three decades, many efforts have been directed by the scientific community designing of multi-modular systems that are capable of capturing most of the useful sunlight and generating charge separated states of prolonged lifetimes with adequate amounts of energy. In this dissertation, we report on the design and synthesis of donor–acceptor conjugates with the goal of modulating the yield and lifetime of their charge separated states and hence, improving the conversion of light energy into chemical potential. In simple donor-acceptor systems, generally, the energy and electron transfer events originate from the singlet excited state of the donor or acceptor and can store the …

Humility and Attachment Style in Adult Romantic Relationships
The goal of this study was to investigate the relationship between adult attachment style, humility, and relationship satisfaction in college student couples. Attachment style--given its significant role in predicting how individuals feel, think, and behave in relationships--was expected to be an important predictor of humility, although this possibility has rarely been studied empirically. The current study found that: (a) attachment anxiety and attachment avoidance were significant, negative predictors of total humility, (b) attachment anxiety (but not attachment avoidance) was a significant, negative predictor of both intrapersonal and interpersonal humility, (c) a romantic partner's attachment avoidance (but not attachment anxiety) was a significant, negative predictor of a target person's relationship satisfaction, and (d) a romantic partner's perceived level of humility was a significant, positive predictor of a target person's relationship satisfaction.

Hydrophobicity of Magnetite Coating on Low Carbon Steel
Superhydrophobic coatings (SHC) with excellent self-cleaning and corrosion resistance property is developed on magnetite coated AISI SAE 1020 steel by using a simple immersion method. Roughness measurement, scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), contact angle measurement (CAM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), potentiodynamic polarization test, electrochemical impedance spectroscopy (EIS), and qualitative characterization of self-cleaning behavior, antifouling property and durability of the coatings are assessed. A water contact angle as high as 152o on the coated surface with excellent self-cleaning and resistivity to corrosion and good longevity in atmospheric air is obtained. Self-cleaning test results prove that these surfaces can find applications in large scale production of engineering materials. Potentiodynamic polarization tests and EIS tests confirm that the superhydrophobic low carbon steel surfaces have better resistance to corrosion compared to bare steel and magnetite coated steel in 3.5% NaCl solution. But the longevity of the coated steel surfaces in 3.5% salt solution is limited, which is revealed by the immersion durability test. However, hydrophobic coatings (HC) have better stability in normal tap water, and it can stay unharmed up to 15 days. Finally, hydrophobic coatings on low carbon steel surface retains hydrophobic …

The Impact of Teacher Professional Development on Student Achievement at a North Texas High School as Measured by End-of-Course Assessments in Algebra I and English Language Arts
The purpose of this study determined if a significant relationship existed between the amount of professional development that teachers participated in and the impact on the classroom instruction that followed. The goal was to study the effect that this had on student achievement in the State of Texas Assessment of Academic Readiness (STAAR) for English 1 and Algebra 1 for students at a large north Texas high school. Testing years for the study included the school years 2013-14, 2014-15, and 2015-16. Additional variables included the work in three areas of teacher professional development over the three-year period. Fourteen teachers, in two subjects, were studied in their implementation of classroom instruction. Particular attention was given to the instructional changes, and the number of hours of professional development in the areas of instruction, technology, and differentiation. Teachers were given opportunities to participate in 18 hours of professional development in all three areas in each of the three years. Teachers were then asked to incorporate the work that they completed each year into their day to day classroom instruction. The goal of the implementation of the professional development in addition to the curricular specifics regarding instruction of state standards was expected to produce …

Impact of Yoga on Mental Well-Being
The present study sought to more rigourously explore outcomes of psychological well-being immediately following a psychotherapeutic yoga class. Specifically, the study hypothesized improvements in state anxiety and subjective well-being as well as an observable relationship between state and trait mindfulness following a yoga intervention, all while controlling for differences between yoga instructors, prior yoga experience, and participant endorsements of psychological symptoms. Previous yoga experience was not found to be a significant factor in any of the tested hypotheses. Findings revealed that psychotherapeutic yoga decreased anxiety and increased subjective well-being, even after controlling for therapist variability, prior yoga experience, and client diagnosis. Results also indicate differential impacts on decreased anxiety and increased subjective well-being by class instructor. This is the first study to examine outcomes of an ongoing yoga based-practices in the naturalistic setting of an outpatient counseling center while rigorously controlling for confounding factors (e.g. therapist variability). Methodological and statistical limitations are discussed in depth, and future directions to improve on this study and clarify the present findings are emphasized.

Implications of Diet in Cardiovascular Disease Risk: Postprandial Changes in Circulating Monocytes and Endotoxemia
It is well established that continual consumption of a diet high in fat leads to the development of chronic conditions such as obesity, cardio metabolic syndrome, and atherosclerosis that are associated with high incidence of cardiovascular disease. Recent studies have identified endotoxin-derived inflammation as a major diving force for the development of these conditions. Our laboratory has recently demonstrated that consumption of a single high-fat meal results in acute postprandial endotoxemia and alters monocyte cell surface adhesion molecule expression and scavenger receptor CD36 expression. These collective projects describe our efforts to understand the physiological significance of these postprandial changes and if supplementation with spore-based probiotics are able to provide any form of protection against these responses that are associated with the onset of atherogenesis.

The Importance of Construct Definition and Specification in Operations Management Structured Model Research: The Case for Quality and Sustainability Constructs in a Decision-Making Model
In the operations management research, the inconsistent use of the same term for different concepts and the use of the similar concepts for different constructs potentially causes theoretical and statistical problems. This research addresses the importance of construct definitions and specification methodologically within the context of quality and sustainability management. It involves three essays using multiple quantitative methods such as partial least squares structural equation modeling and multiple regression in different consumer decision-making models in the automobile industry. In the first two essays, a comprehensive literature review results in definition and contextualization of the quality and sustainability constructs as applied to operations management and marketing research. The relationships of these constructs with consumer behavior are empirically tested. Building upon the first two essays, the third essay addresses the methodological issues on formative and reflective measurements by summarizing a procedure of validating formative measurements. The quality construct was used to illustrate the methodology. This research contributes to the literature, theory, and practices in the area of quality and sustainability management.

Influences on Latino Males' Enrollment in Four-Year Colleges
The purpose of this study was to explore characteristics that influence Latino male students' enrollment in four-year colleges. This study utilized a mixed-methods approach and acquired information specifically pertaining to the high school Latino male population. Participants for the study included Latino male high school students in Grades 9-12, parents of Latino male high school students in Grades 9-12, and counselors of high school students in Grades 9-12. The study was conducted across two campuses. Data for student and parent participants were obtained through an online survey questionnaire and counselor data was obtained through face-to-face semi-structured interviews. The results of this study reveal that there are influential characteristics that contribute to Latino males' potential enrollment in college. Of the data obtained from student participants, 70.2% of participants on Campus 1 and 90.5% of participants on Campus 2 planned on attending college. Responses from parent surveys found that 85.8% of parents had expectations for their Latino male student to attend college. Through the semi-structured focus group interviews, it was found that the school district and campuses in which the study was conducted had several procedures or processes in place to positively encourage Latino male student enrollment in four-year colleges.

The Inspiration behind Compositions for Clarinetist Frederick Thurston
Frederick Thurston was a prominent British clarinet performer and teacher in the first half of the 20th century. Due to the brevity of his life and the impact of two world wars, Thurston's legacy is often overlooked among clarinetists in the United States. Thurston's playing inspired 19 composers to write 22 solo and chamber works for him, none of which he personally commissioned. The purpose of this document is to provide a comprehensive biography of Thurston's career as clarinet performer and teacher with a complete bibliography of compositions written for him. With biographical knowledge and access to the few extant recordings of Thurston's playing, clarinetists may gain a fuller understanding of Thurston's ideal clarinet sound and musical ideas. These resources are necessary in order to recognize the qualities about his playing that inspired composers to write for him and to perform these works with the composers' inspiration in mind. Despite the vast list of works written for and dedicated to Thurston, clarinet players in the United States are not familiar with many of these works, and available resources do not include a complete listing. Much of this repertoire remains unexplored and unrecorded yet is suitable for intermediate to advanced level …

Interpersonal Functioning and Experiential Avoidance: Considering New Measurements and Their Implications
Interpersonal functioning can be conceptualized as being comprised of social skills, connectedness, social cognition, and intimacy. A concept that is related to an examination of interpersonal functioning is experiential avoidance (EA), which can be defined as an unwillingness to experience or remain in contact with unpleasant private events through attempts to avoid or escape from these experience. An examination of EA and interpersonal functioning has not previously taken place. This study thus sought to fill that gap in the literature. The availability of a behavioral-oriented measure of interpersonal functioning aided in this investigation. The relationship of EA and interpersonal functioning to depression and anxiety were also examined, in order to evaluate their relative contributions to psychopathology. Overall, it was found that EA and interpersonal functioning were significantly related. However, the dimensions of EA varied in strength with respect to their relationships with interpersonal functioning. Further, it was found that interpersonal functioning predicted unique variance in both depression and anxiety, and partially mediated the relationship between EA and both anxiety and depression. These results might guide the development of treatment programs and add support to the use of treatments with trans-diagnostic targets.

Interpretation and Execution of Chords on the Double Bass from Select Movements of the Bach Cello Suites
The Bach Cello Suites have become widely transcribed and studied on the double bass. They have also become essential teaching material as most US orchestra auditions demand solo Bach for bass auditions. Transcribing the chords in Bach Cello Suites presents many difficulties on the bass because of the different tuning of our instrument (cello in 5ths; double bass in 4ths). There is no unified solution to all the problems presented in chord playing at this time. The purpose of this project, therefore is to give bass players solutions to the problems by looking at historical interpretation of chords, technical execution of the chords on cello and bass, tonal and resonance considerations and fingering solutions. The chords chosen represent the most common and most difficult to transcribe to the double bass from the Cello Suites.

An Investigation of the Value of Bank Capital in the Context of Mergers and Acquisitions in the Banking Industry
I analyzed a sample of 228 U.S. bank acquisitions announced from January 1996 to December 2015. This dissertation explores whether acquiring banks pay more for targets with a higher capital ratio using a better measure of goodwill than previous studies. Specifically, this study uses manually collected goodwill to evaluate the value of bank capital, a measure that I argue is superior to those used in prior studies. I collect information about goodwill for 203 merger and acquisition (M&A) deals. I find a positive relation between the target's capital ratio and the goodwill paid for targets, which is consistent with previous cross sectional analysis on the relation between bank equity capital and value. This positive relation exists in the deals with a bank target, but not when the target is a savings institution. Furthermore, I find that the positive association between the target's capital ratio and goodwill paid by the acquirer only exists in the sample of acquisitions of banks announced before the 2007 financial crisis. This dissertation also evaluates the value of bank capital by analyzing the changes in shareholders' wealth around the announcement of M&As. My empirical analysis shows that banking mergers create value for the shareholder of targets. …
