An Assessment of a Hospice and Palliative Care Partnership Program
This project attempts to describe how a hospice and palliative care partnership program works. Through the assessment of one such program, the researcher sought to find out the essential components of the partnership including how the two partner organizations interact and work together. Data was collected using various methods: document review of organization documents such as newsletters, annual or quarterly reports, brochures and other available literature e.g. materials on organizations’ website and on social media; in-depth interviews with stakeholders of both organizations that included staff and board members; observation of staff working; and participant observation during organization events. The findings of the research shows that in order for organizations to have an effective partnership program in place, both partners need to have strong leadership in place, possess a willingness to learn from each other, maintain regular communication, and visit each other regularly. With this in place, several outcomes of the program are likely such as: increasing advocacy for hospice and palliative care, increasing visibility of the organizations both nationally and internationally, and provides an opportunity for organizations to network with other organizations in their locality in order to achieve partnership objectives. The study further reveals that global collaborations in the …

Assessment of Cognitive Performance in Mixed Martial Arts Athletes
Incidents and awareness of sports-related concussion have grown in recent years, attracting attention in both the academic and popular press. These concussions can lead to the rapid onset of neurological dysfunctions, as well as a variety of subjective symptoms. Although concussive sequelae are typically considered transient, debate remains about the persistent effects of repeated traumatic contact during sport participation. Although research has examined the complications of head trauma found in traditionally popular sports (e.g., football, soccer, boxing), little research has focused on the growing sport of mixed-martial-arts (MMA). Research specifically pertaining to MMA is in nascent stages, but to-date studies suggest that concussive injuries for this sport are prevalent and the training regimens of these athletes may place them at a high risk for concussive or subconcussive head traumas—as well as the accompanying neurological difficulties. The current study is the first to assess cognitive profiles of MMA athletes using an objective neuropsychological assessment instrument. Among 56 athletes (28 MMA athletes and 28 athletes not exposed to head traumas), no neuropsychological differences were found between groups of athletes. Additionally, no aspects of MMA training regimen shared a reliable relationship with neuropsychological performance or subjective concussive symptoms. This suggests non-professional participation in …

Assessment of Post-earthquake Building Damage Using High-resolution Satellite Images and LiDAR Data - a Case Study From Port-au-prince, Haiti
When an earthquake happens, one of the most important tasks of disaster managers is to conduct damage assessment; this is mostly done from remotely sensed data. This study presents a new method for building detection and damage assessment using high-resolution satellite images and LiDAR data from Port-au-Prince, Haiti. A graph-cut method is used for building detection due to its advantages compared to traditional methods such as the Hough transform. Results of two methods are compared to understand how much our proposed technique is effective. Afterwards, sensitivity analysis is performed to show the effect of image resolution on the efficiency of our method. Results are in four groups. First: based on two criteria for sensitivity analysis, completeness and correctness, the more efficient method is graph-cut, and the final building mask layer is used for damage assessment. Next, building damage assessment is done using change detection technique from two images from period of before and after the earthquake. Third, to integrate LiDAR data and damage assessment, we showed there is a strong relationship between terrain roughness variables that are calculated using digital surface models. Finally, open street map and normalized digital surface model are used to detect possible road blockages. Results of …

Athletic Trainers and Sport Psychology: Knowledge, Experience and Attitudes
Certified athletic trainers (ATCs) play a unique role in sport environments as the primary medical staff available to athletes. Thus, ATCs are well positioned to oversee athletes’ physical and psychological well-being. Although sport psychologists (SPs) have been identified as a potential resource for ATCs, previous studies have reported a lack of collaboration between SPs and ATCs. This study aimed to (a) examine ATCs’ views regarding professional roles for both ATCs and SPs, (b) explore ATCs’ referral behaviors, (c) evaluate ATCs belief in the credibility of sport psychology across demographic (i.e., gender, age) and experiential variables (i.e., access to SPs), and (d) examine ATCs’ involvement in sport psychology. Four hundred ninety-six ATCs (265 men, 231 women) completed and returned the questionnaire. ATCs viewed assisting in the psychological recovery of athletes as the most acceptable professional role for fellow ATCs; aiding in the psychological recovery of injured athletes and teach mental skills were identified by ATCs as the most appropriate roles for SPs. In considering an athlete experiencing interpersonal difficulties (e.g., relationship problems), a mixed design ANOVA revealed a ATC sex by referral option interaction; female and male ATCs indicated they would likely refer the athlete to a counselor/therapist, followed by a …

Atomistic Computer Simulations of Diffusion Mechanisms in Lithium Lanthanum Titanate Solid State Electrolytes for Lithium Ion Batteries
Solid state lithium ion electrolytes are important to the development of next generation safer and high power density lithium ion batteries. Perovskite-structured LLT is a promising solid electrolyte with high lithium ion conductivity. LLT also serves as a good model system to understand lithium ion diffusion behaviors in solids. In this thesis, molecular dynamics and related atomistic computer simulations were used to study the diffusion behavior and diffusion mechanism in bulk crystal and grain boundary in lithium lanthanum titanate (LLT) solid state electrolytes. The effects of defect concentration on the structure and lithium ion diffusion behaviors in LLT were systematically studied and the lithium ion self-diffusion and diffusion energy barrier were investigated by both dynamic simulations and static calculations using the nudged elastic band (NEB) method. The simulation results show that there exist an optimal vacancy concentration at around x=0.067 at which lithium ions have the highest diffusion coefficient and the lowest diffusion energy barrier. The lowest energy barrier from dynamics simulations was found to be around 0.22 eV, which compared favorably with 0.19 eV from static NEB calculations. It was also found that lithium ions diffuse through bottleneck structures made of oxygen ions, which expand in dimension by 8-10% …

Autonomic Failure Identification and Diagnosis for Building Dependable Cloud Computing Systems
The increasingly popular cloud-computing paradigm provides on-demand access to computing and storage with the appearance of unlimited resources. Users are given access to a variety of data and software utilities to manage their work. Users rent virtual resources and pay for only what they use. In spite of the many benefits that cloud computing promises, the lack of dependability in shared virtualized infrastructures is a major obstacle for its wider adoption, especially for mission-critical applications. Virtualization and multi-tenancy increase system complexity and dynamicity. They introduce new sources of failure degrading the dependability of cloud computing systems. To assure cloud dependability, in my dissertation research, I develop autonomic failure identification and diagnosis techniques that are crucial for understanding emergent, cloud-wide phenomena and self-managing resource burdens for cloud availability and productivity enhancement. We study the runtime cloud performance data collected from a cloud test-bed and by using traces from production cloud systems. We define cloud signatures including those metrics that are most relevant to failure instances. We exploit profiled cloud performance data in both time and frequency domain to identify anomalous cloud behaviors and leverage cloud metric subspace analysis to automate the diagnosis of observed failures. We implement a prototype of the …

Babel: a Composition for Rock Band, Soprano Quartet, and Chamber Ensemble—music and Critical Essay
Babel is a work for rock ‘n’ roll band (two electric guitars, electric bass, drum set), four soprano singers, and a twenty-one instrument mixed chamber ensemble. The 50-minute composition is based on the Tower of Babel story in Genesis 11:1-9, and the four-movement structure is derived from the form of this narrative. The first movement, “building rebellion,” establishes man’s intent to build a grand city and tower in a rebellion against God, while the second movement, “seeing/coming down,” describes the all-seeing God’s knowledge of man’s rebellion and God’s descent to the city. Movements three and four, “confusion” and “scatter,” depict the actions of God, confusing humankind’s language and scattering him over the earth. This project fuses rock ‘n’ roll influences with contemporary classical improvisation, creating a work that is sonically and dynamically excessive. One compositional goal was to use small amounts of material as the impetus for directed improvisation, which would be developed to create intricate and evolving textures. Each movement’s score is confined to a single page of music per part, necessitating highly graphic and aleatoric notation. The musical history and musicianship of each player greatly shapes the sonic outcome of Babel. Rigorous structure was mixed with extra-musical associations …

Bank Capital, Efficient Market Hypothesis, and Bank Borrowing During the Financial Crisis of 2007 and 2008
During the Great Recession of 2007 and 2008, liquidity and credit dried up, threatening the stability of financial institutions, particularly the banking firms. Traditional source of funds from the last resort, the Discount Window of the Federal Reserve System, failed to remedy the liquidity problem. To assuage the liquidity and credit problem, the Federal Reserve System established several emergency lending facilities and provided unprecedented amount of loans to the banking industry. Using a dataset published by Bloomberg LLP in the aftermaths of the financial crisis, which contains daily loan balances from the Fed, I conduct an event study to test whether financial markets are efficient in reflecting all public, anticipated and classified information in security prices. The most important contribution of this dissertation to the finance discipline and literature is the investigation and analysis of the Fed’s unprecedented loans to the banking industry during the Great Recession and the market reaction to it. The second major contribution of this study is the empirical test of strong form efficient market hypothesis, which has not been feasible due to legal data challenges. This dissertation has other contributions to the finance discipline and banking research. First, I develop an algorithm for measuring the …

“Before I Die…”: Original Composition with a Critical Essay Exploring the Techniques of Six Crossover Composers
Candy Chang developed a public art installation where people are given the opportunity to write their answers to "Before I Die I want to ________." in a public space. I created one of these walls in Denton, TX and set it to music in a 12 minutes and 42 second piece titled Before I Die..., which combines elements of South Indian carnatic music, gospel, R&B, jazz fusion, and minimalism. The composition was influenced by the music of several crossover artists Becca Stevens, Michael League (Snarky Puppy), Nico Muhly, Poovalur Sriji, Tigran Hamasyan, and James Blake. Crossover music, fusion, and third-stream are all synonymous terms used to describe music where multiple genres or styles are authentically combined. The purpose of this thesis is to examine the balance of musical elements in crossover works as well as how specific works composed by the artists mentioned have influenced the creation of the Before I Die... piece.

The Behavioral Economics of Effort
Although response effort is considered a dimension of the cost to obtain reinforcement, little research has examined the economic impact of effort on demand for food. The goal of the present study was to explore the relationship between effort and demand. Three Sprague Dawley rats were trained to press a force transducer under a series of fixed-ratio schedules (1, 10, 18, 32, 56, 100, 180, 320, and 560) under different force requirements (5.6 g and 56 g). Thus, nominal unit price (responses / food) remained constant while minimal response force requirements varied. Using a force transducer allowed the measurement of responses failing to meet the minimal force requirement (i.e. “subcriterion responses”), an advantage over prior approaches using weighted levers to manipulate effort. Consistent with prior research, increasing the unit price decreased food consumption, and raising minimum force requirements further reduced demand for food. Additionally, increasing the force requirement produced subcriterion responses. Analysis indicated that subcriterion responses did not create incidental changes in unit price. Obtained force data revealed that including obtained forces in unit price calculations provided better predictions of consumption when compared to using criterion force requirements.

Béla Bartók’s Editorial Input As Seen in His Edition of Piano Sonata Hobxvi:49 in E Flat Major by Joseph Haydn
Béla Bartók (1881-1945), one of the twentieth century’s most significant composers, is also well known as an ethnomusicologist and concert pianist. However, Bartók’s work as a pedagogue and as an editor has received relatively little scholarly attention, despite famous pupils and despite his preparation of numerous critical and educational editions of his own and others’ works. While the critical editions are few, a significant number of Bartók’s editions of piano works have an educational purpose; these editions contain highly detailed performing indications and hold substantial potential for investigating Bartók’s ideas on the performance of works by other composers. Bartók edited nineteen piano sonatas by Haydn for educational purposes between 1911 and 1920. Bartók’s edition of Haydn’s Piano Sonata Hob.XVI:49 in E-flat Major is compared with both the first edition and the facsimile of the manuscript, with a focus on articulation, pedaling, dynamics, fingering, and other significant markings such as indications of expression and ornamentations. This document examines Bartók’s editorial input in this edition as an exemplar of his stylistic principles, and explores the value of Bartók’s Haydn editions as performing editions by critically examining both his editorial contributions and possible execution issues. This study thus provides an understanding of Bartók’s …

Belfast: Perspectives of a City
This thesis film is an examination of my evolving perspectives and understanding of my Irish heritage as I travel to the city of Belfast, Northern Ireland. Through the course of a year and a half, I traveled to Belfast to explore the modern state of the sectarian conflicts between the Catholic and Protestant communities. Through the use of personal reflection, historical research, interviews with local residents, and on-location experiential learning, I began to learn not only about the modern state of Belfast and its economic and social climate, but also about the complexities of personal cultural identification and the concept of “truth” and “mutual guilt” when associated with acts of violence. With the use of the short documentary as the medium of choice, I am able to relay to audiences not only my own personal reflection of identity and history, but then allow them to reflect on their own perspectives as well, helping to create sincere moments of personal thought and reflections.

Beliefs of Mathematics Pre-service Teachers About Project-based Learning
This study explored the beliefs of pre-service secondary mathematics teachers about project-based learning (PBL), as they encountered a project-based learning high school where they implemented a project-based unit of instruction. A qualitative study was conducted with one undergraduate cohort in a higher education science, technology, engineering, and mathematics (STEM) national initiative that has 40 U.S. replication sites. Using teaching philosophy statements and focus group discussions, the beliefs of STEM pre-service secondary teachers are made visible. The findings from this study reveal a recurring theme: the process of how these pre-service teachers seemed to evolve and mature as teachers, from novice toward becoming an expert, as they asked themselves internal questions that are common to developing teachers. These pre-service STEM teachers experienced 1) internal questions about their own growth as a potential teacher, as evidenced through their verbal and written statements; 2) tension between PBL content and pedagogy; and 3) tension between practice and theory. The findings also infer that there are potential critical variables that may contribute to pre-service teachers’ beliefs. Those variables identified were the following: 1) the sequence of when the project-based instruction (PBI) course was taken; 2) time, as related to when the participant took the PBI …

A Biopsychosocial Model of Dietary Restraint in Early Adolescent Boys
The current study replicated and extended previous research by examining empirically the direct and indirect influence of social pressure (to lose weight and diet), social body comparisons, internalization of the thin ideal, body dissatisfaction, self-esteem, and cardiorespiratory fitness on self-reported dietary restraint in a diverse sample of middle school boys (n = 663); Mage was 12.49 years (SD = .99). With IRB approval, parental consent, and child assent, during annual FITNESSGRAM testing, participants completed questionnaires that measured the study’s constructs. Cardiorespiratory fitness (CRF) was determined by the boys’ performance on the PACER running test. The proposed model was examined using structural equation modeling (SEM). Because measures demonstrated univariate and multivariate normality, the maximum likelihood procedure within EQS to examine the measurement and structural models was used. Fit was determined using a two-index procedure. Participants were randomly split into exploratory (Sample A - 331) and confirmatory (Sample B - 332) samples. For Sample A, the measurement and structural models fit the data well. The structural model was confirmed in Sample B, with the same paths being significant and nonsignficant. For both Sample A and Sample B, 35% of the Dietary Restraint variance was explained. These findings support a multifactorial approach to …

Breaking the Doubler Barrier: Using Sy Brandon’sDivertissement to Demonstrate a Practical Approach to Performing Multiple WoodwindWorks
Multiple woodwind training is ideal for securing certain types of employment; however, with so many different instruments, performance standards on each are difficult to maintain. Furthermore, for many multiple woodwind players, proficiency on all woodwinds ceases to be a top priority after graduation, even though they continue to market themselves as highly proficient on all of these instruments. The problem for most begins with what it means to be proficient on each instrument. The technical demands of multiple woodwind performance vary widely, but often a performance calls for complete proficiency on a variety of instruments. Multiple woodwind players who lack in professional level proficiency damage the credibility of the field and jeopardize employment opportunities for others. This study aims to address the common problems involving proficiency and to help multiple woodwind players, band directors, and doublers become familiar with and overcome these common pitfalls. Sy Brandon’s Divertissement provides an outstanding platform to address problems and provide solutions for multiple wind players, band directors, and doublers. This dissertation serves as a multiple woodwind specialist’s resource for maximum efficiency in learning and playing repertoire that involves multiple woodwinds, such as musicals, and other multiple woodwind genres.

brk1 and dcd1 Act Synergistically in Subsidiary Cell Formation in Zea mays
Subsidiary mother cell (SMC) divisions during stomatal complex formation in Zea mays are asymmetric generating a small subsidiary cell (SC) and a larger epidermal cell. Mutants with a high number of abnormally shaped subsidiary cells include the brick1 (brk1) and discordia1 (dcd1) mutants. BRK1 is homologous to HSPC300, an ARP2/3 complex activator, and is involved in actin nucleation while DCD1 is a regulatory subunit of the PP2A phosphatase needed for microtubule generation (Frank and Smith, 2002; Wright et al. 2009). Possible causes of the abnormal SCs in brk1 mutants include a failure of the SMC nucleus to polarize in advance of mitosis, no actin patch, and transverse and/or no PPBs (Gallagher and Smith, 2000; Panteris et al 2006). The abnormal subsidiary mother cell division in dcd1 is due to correctly localized, but disorganized preprophase bands (PPBs; Wright et al. 2009). The observation that brk1 has defects in PPB formation and that the dcd1 phenotype is enhanced by the application of actin inhibitors led us to examine the dcd1; brk1 double mutant (Gallagher and Smith, 1999). We found that dcd1; brk1 double mutants demonstrate a higher percentage of aberrant SCs than the single mutants combined suggesting that these two mutations have …

Bundle of Joy: Pregnancy, Coping, and Depressive Symptoms in Adolescent Girls
Using the stress process model, the relationship between pregnancy and depressive symptoms among adolescent girls was investigated. This model posits that stress resulting from social location and related disruptive life events may indirectly affect health by eroding coping, mastery, or social support mechanisms. The effect of low income, minority status and pregnancy on coping processes in adolescent girls was hypothesized and tested. Communication with parents, involvement in activities, and success in school were examined as positive coping strategies. Smoking tobacco, heavy alcohol use, and drug use were examined as negative coping. Data from the National Survey on Drug Use and Health were analyzed. After combining the available cases from the 2006, 2007, and 2008 datasets, selecting girls aged from 12 to 17 years, and removing missing cases; the sample consisted of a total of 22,854 adolescents. A series of binary logistic regression models were estimated. Findings included that coping strategies partially mediate the relationship between pregnancy and depressive symptoms. In particular, success in school, smoking tobacco, and drug abuse played a mediating role. When coping was accounted for, the relationship between pregnancy and depressive symptoms was reduced and became only marginally significant. Implications of the study include a focus on …

Business/it Alignment: the Impact of Incentive Plans on the Development of Shared Vision
This study, utilizing Preston and Karahanna’s framework for shared vision development and Agency Theory, explores the impact of vision development factors and factors associated with incentive plans on shared vision and alignment. Results of the study confirm the strong relationship between shared vision and alignment, and indicate that having an effective management team is important with respect to developing and maintaining shared vision and alignment within the organization. Several vision development factors such as using the language of the business, participation on the top management team (TMT), and having knowledge of the business impact shared vision through their influence on teamwork. Also, results of this study suggest that participation on the TMT by the CIO/IT leader is more important than the individual’s position in the organizational hierarchy. In addition, attributes associated with incentive plans such as achievable and clear measures, measures linked to organizational goals, measures that align the interests of the individual with those of the organization, regular plan reviews, and using a balanced scorecard approach with respect to incentive plan design positively impact teamwork and shared vision. For practitioners, this highlights the importance of incentive plans as powerful tools that can be used to reinforce shared vision, effective …

Capital Ships, Commerce, and Coalition: British Strategy in the Mediterranean Theater, 1793
In 1793, Great Britain embarked on a war against Revolutionary France to reestablish a balance of power in Europe. Traditional assessments among historians consider British war planning at the ministerial level during the First Coalition to be incompetent and haphazard. This work reassesses decision making of the leading strategists in the British Cabinet in the development of a theater in the Mediterranean by examining political, diplomatic, and military influences. William Pitt the Younger and his controlling ministers pursued a conservative strategy in the Mediterranean, reliant on Allies in the region to contain French armies and ideas inside the Alps and the Pyrenees. Dependent on British naval power, the Cabinet sought to weaken the French war effort by targeting trade in the region. Throughout the first half of 1793, the British government remained fixed on this conservative, traditional approach to France. However, with the fall of Toulon in August of 1793, decisions made by Admiral Samuel Hood in command of forces in the Mediterranean radicalized British policy towards the Revolution while undermining the construct of the Coalition. The inconsistencies in strategic thought political decisions created stagnation, wasting the opportunities gained by the Counter-revolutionary movements in southern France. As a result, reinvigorated …

Caring for Cancer: Understanding the Access and Perceptions of Psychosocial Cancer Services in North Texas
It is estimated that nearly 14.5 million Americans are living with cancer today. A commonly overlooked component to quality cancer care, as defined by the Institute of Medicine, is the role of psychological and social support. Better known as psychosocial support, these needs reflect a broad spectrum of obstacles or assets in an individual’s personal life that may help or hinder their healing experience. Some psychosocial examples include coping skills, transportation to medical appointments, or appropriate knowledge to mitigate the physical impacts of the cancer process. Research has shown that by addressing these potential needs, a better health outcome may be achieved for cancer patients. Through participant observation at local psychosocial service establishments and through semi-structured interviews with service providers and adults diagnosed with cancer living in the Dallas-Fort Worth region, this thesis research seeks to explore how local cancer patients are learning of psychosocial services available to them, what barriers may exist in accessing these services, and what individuals may be doing to address their psychosocial needs, both formally or informally. Results yielded recommendations for local psychosocial providers to adjust their marketing of services and kinds of services offered as well as yielded recommendations for future academic research.

Carlos Guastavino’s Sonata Para Trombón O Trompa Y Piano: Analysis of Argentine Song and Formal Western Music Tradition Applied to Trombone Repertoire
Very few Latin American pieces for trombone as a solo instrument have entered the canon of trombone repertoire worldwide, despite the large number of compositions in this medium. Therefore, when a major composer writes a full sonata for trombone efforts need to be made to bring these compositions to light. The Argentine composer Carlos Guastavino wrote a sonata for trombone and piano that is virtually unknown outside of Argentina, despite the composer’s importance. He is known for his artistic choice of cultivating a traditional romantic style of composition apart from the new tendencies and influences of the artistic novelties of the twentieth century. Guastavino’s artistic position is very clear in the sonata’s highly strict formal organization and Guastavino’s unique treatment of tonality and modality. He was also loyal to his own style as composer, which is ultimately an Argentine song style. He utilized the lyrical qualities of the trombone to convey the type of melodic approach that he used in his vocal works. This paper investigates the Argentine song and Western sonata conventions featured on Carlos Guastavino’s Sonata para Trombón o Trompa y Piano. The paper argues that these features represent his unique approach to musical composition in the twentieth …

A Century of Overproduction in American Agriculture
American agriculture in the twentieth century underwent immense transformations. The triumphs in agriculture are emblematic of post-war American progress and expansion but do not accurately depict the evolution of American agriculture throughout an entire century of agricultural depression and economic failure. Some characteristics of this evolution are unprecedented efficiency in terms of output per capita, rapid industrialization and mechanization, the gradual slip of agriculture's portion of GNP, and an exodus of millions of farmers from agriculture leading to fewer and larger farms. The purpose of this thesis is to provide an environmental history and political ecology of overproduction, which has lead to constant surpluses, federal price and subsidy intervention, and environmental concerns about sustainability and food safety. This project explores the political economy of output maximization during these years, roughly from WWI through the present, studying various environmental, economic, and social effects of overproduction and output maximization. The complex eco system of modern agriculture is heavily impacted by the political and economic systems in which it is intrinsically embedded, obfuscating hopes of food and agricultural reforms on many different levels. Overproduction and surplus are central to modern agriculture and to the food that has fueled American bodies for decades. Studying …

The Changing Symbolic Images of the Trumpet: Bologna and Venice in the Seventeenth Century
The trumpet is among the most ancient of all musical instruments, and an examination of its history reveals that it has consistently maintained important and specific symbolic roles in society. Although from its origins this symbolic identity was linked to the instrument’s limited ceremonial and signaling function, the seventeenth century represents a period in which a variety of new roles and identities emerged. Bologna and Venice represent the two most important centers for trumpet writing in Italy during the seventeenth century. Because of the differing ideologies at work in these cities, two distinctive symbolic images of the instrument and two different ways of writing for it emerged. The trumpet’s ecclesiastic role in Bologna and its participation in Venetian opera put the instrument at the service of two societies, one centered around the Church, and another around a more permissive state. Against the backdrop of the social and political structures in Venice and Bologna, and through an examination of its newly-emerging musical roles in each city, the trumpet’s changing identities during a most important point in the history of the instrument will be examined.
