Wayne Barrington was a tenured member of the Chicago Symphony Orchestra for ten years and held positions with the LA Philharmonic, Pittsburgh Symphony, and San Antonio Symphony. He was an early member of the Chicago Brass Ensemble and a founding member of the LA Brass. While performing in these major orchestras and brass quintets, Barrington played alongside many notable musicians including Philip Farkas, Forrest Standley, Arnold Jacobs, Bud Herseth, Frank Crisafulli, Miles Anderson, Roger Bobo, David Krebhiel, and Christopher Leuba. Many of these musicians mentioned have received recognition in books and dissertations for their achievements as performers and pedagogues. Barrington, however, has not. Barrington was also a founding member and secretary of ICSOM, the International Conference of Symphony and Orchestra musicians. This organization helped improve the working conditions for musicians by creating transparency of orchestra salaries and giving musicians throughout the United States and Canada a say in ratifying their contracts. After Barrington's years as a symphonic musician, he transitioned from a full-time performer to a full-time pedagogue and taught for over three decades at the University of Texas at Austin, and several of his students went on to have successful careers of their own. His impressive career and influence …

The role of Odierno's III Corps as MNC-I has failed to receive sufficient attention from studies of the 2007-2008 surge of U.S. forces in Iraq. However, was Odierno's employment of military force in time, space, and purpose based on the logic of conventional military operations that laid the groundwork for the successes gained in 2007 and 2008. III Corps's achievements as an operational headquarters were rooted in the successful application of operational art. Operational art is a way to conceptualize how to fight wars using campaigns of multiple, simultaneous, and successive operations across a theater of operations to achieve a unifying goal. While neither downplaying nor minimizing the importance of Army COIN principles, a study of MNC-I's December 2006-February 2008 campaign in Iraq through the neglected prism of operational art suggests that the campaign's success was due to the successful application of already established operational principles rather than from a revolution in the profession of arms.

Carl A. Helmecke, like many German Americans marginalized by the anti-Germanism of the First World War and interwar period, believed that democracy had failed him. A professor with a doctoral degree in social philosophy, he regularly wrote newsletter columns declaring that the emphasis on individualism in the United States had allowed antidemocratic forces to corrupt the government, oppress citizens, and politicize schools and institutions for propaganda purposes. Moreover, widespread hunger and unemployment during the Great Depression added to the long list of failures attributable to democracy. What the United States needed, Helmecke thought, was political change, and he believed that the Nazi regime in his homeland, albeit flawed, had much to offer. In 1937, he went on a teaching sabbatical to Nazi Germany to study the Third Reich's education and social programs. When he returned to the United States, he began promoting Nazi ideals about education and labor camps. Although Hitler's 1939 invasion of Poland, followed by the United States entry into World War II, brought his fascist illusions for political change in the United States to an abrupt end, his belief in the correctness of an autocratic system of governance for Germany rather than that of the western democracies …

Tinnitus, or the perception of sound in the absence of external acoustic stimuli, is a common condition that impacts approximately 10-15% of the United States population, with similar prevalence rates reported in other countries. Current diagnosis of tinnitus relies on case history and audiometric testing, which depend on responses provided by the patient. To date, there is no objective test that can be used for tinnitus diagnosis, despite the high prevalence and significant financial impacts of this condition. Cortical auditory evoked potentials have shown promise in their ability to assess not only the integrity of the auditory system, but also higher level preattentional and cognitive processing. For this study, the pitch-matched tinnitus frequency was used to evoke an auditory late response. Double oddball paradigms with the tinnitus frequency as the deviant stimuli were also used to evoke a mismatch negativity and P300 to determine where along the auditory pathway biomarkers of tinnitus may exist. The results of this study suggest that when the tinnitus frequency is incorporated into paradigms designed to produce cortical auditory evoked potentials, differences exist between participants with tinnitus and matched controls without tinnitus. Individuals with tinnitus exhibit smaller MMN amplitudes and area under the curve and …

Louisiana Saturday Nights is a collection of poetry and accompanying critical introduction written for the doctorate in Literature and Creative Writing.

Despite significant progress in the acceptance and celebration of LGBTQ+ individuals, there is overwhelming evidence that sexual minorities still face disproportionate levels of health inequity compared to their heterosexual peers. Relative to their heterosexual peers, LGBTQ+ emerging adults may encounter unique challenges with discrimination, stigma, and limited social support as they navigate changes in their educational and occupational environments. Additionally, within the broader public health and LGBTQ+ mental health literature, little is known about the mental health service utilization of sexual minority emerging adults. To address these empirical gaps, a sample of 98 LGBTQ+ emerging adults completed self-report measures of heterosexist discrimination experiences, mental health symptoms, LGBTQ+ positive identity, LGBTQ+ community connectedness, and mental health service utilization. The present study found that LGBTQ+ positive identity and LGBTQ+ community connectedness did not attenuate the significant positive relationship between discrimination and negative mental health outcomes. The present study also found that LGBTQ+ positive identity predicted greater likelihood of mental health service utilization, whereas LGBTQ+ community connectedness did not. Finally, exploratory qualitative analyses yielded deeper understanding of relationships between LGBTQ+ positive identity, LGBTQ+ community connectedness, mental health service utilization, and resilience among sexual minority emerging adults. Implications and future directions for empirical research …

This study explored issues related to the adoption and implementation of electronic health record (EHR) systems including building the awareness, knowledge, and experience of physicians toward cyber hygiene. This study used a qualitative research method to assess (a) the barriers to EHR systems adoption and implementation in Kuwait and (b) the level of awareness, knowledge and experiences related to cyber hygiene practices in Kuwait. The findings of the study supported the conceptual framework used to guide the research of the factors impacting the adoption and implementation of EHR systems in Kuwait as well as explore the level of awareness, knowledge, and experience of physicians about both EHR systems and cyber hygiene. The results from the systematic literature review analysis identified seven major barriers. These are financial barriers, time, difficulty of using technology, lack of support, negative attitude, legal and ethical (policies), and cultural barriers. The findings from the semistructured interviews supported the literature findings and provided more in-depth insights into the structural and social issues affecting the adoption and implementation of EHR systems. Given that Kuwait is a member of the Gulf Cooperation Countries (GCC), the results from the literature analysis showed that the problems in Kuwait are similar to …

The Luftwaffe Field Divisions have remained on the periphery of World War II historiography for over seventy years, overshadowed by the myth of German military excellence during the conflict. The Heer is still known for lightning-quick attacks, brutal firepower, ably trained soldiers, and formidable success on the battlefield; an army of almost faceless, remorseless pain that grimly and efficiently faced down the Allies until the very end. Only recently, flaws have begun opening in this pristine picture as historians have examined how quickly the quality of the German army deteriorated from 1942-onward. Despite the vast landscape of scholarship on the war and the recent historical analysis of the weaknesses the Germans suffered, serious study on the creation and management of the Luftwaffe Field Divisions has been sparse. What has been written about them since 1945 has done little to offer a full picture of the units, their creation, or their significance to the German war effort. The purpose of this study was to fulfill this need by answering the necessary questions about the divisions, provide a complete history of the units, and place the LwFDs properly within the historiography of the Second World War.

The purpose of this research was two-fold: (1) further validate the Virtual Reality Stroop Task HMMWV [VRST; Stroop stimuli embedded within a virtual high mobility multipurpose wheeled vehicle] via a comparison of the 3-dimensional VRST factor structure to that of a 2-dimensional computerized version of the Stroop task; and (2) model the performance of machine learning [ML] classifiers and hyper-parameters for an adaptive version of the VRST. Both the 3-D VRST and 2-D computerized Stroop tasks produced two-factor solutions: an accuracy factor and a reaction time factor. The factors had low correlations suggesting participants may be focusing on either responding to stimuli accurately or swiftly. In future studies researchers may want to consider throughput, a measure of correct responses per unit of time. The assessment of naive Bayes (NB), k-nearest neighbors (kNN), and support vector machines (SVM) machine learning classifiers found that SVM classifiers tended to have the highest accuracies and greatest areas under the curve when classifying users as high or low performers. NB also performed well but kNN algorithms did not. As such, SVM and NB may be the best candidates for creation of an adaptive version of the VRST.

Since 2009, the suicide completion rate for military service members and veterans (SMVs) has exceeded rates in civilian populations, with risk highest among young, male veterans. Suicide risk factors include psychiatric illness, low social support, and repeated or prolonged exposure to traumatic events. Recent research further suggests that the experience of unresolved morally injurious events (MIEs) may create lasting feelings of guilt and shame that contribute to psychiatric illness. Additionally, adult attachment plays an important role in coping responses and relational strategies and may influence the degree to which SMVs experience helplessness and isolation that foster suicidal ideation. Protective factors such as social connectedness are important mitigating factors, substantially reducing the risk of suicidality. In the present sample of 206 combat SMVs, higher suicidal ideation was directly correlated with more MIEs, higher attachment avoidance and anxiety, and lower social support. Although neither social support nor attachment anxiety moderated the link between MIEs and suicidal ideation, a significant interaction between attachment avoidance and MIEs emerged, suggesting that higher attachment avoidance increases the risk for suicidal ideation among SMVs reporting more experiences of moral injury. Additionally, findings suggest that higher levels of social support buffer the detrimental effects of attachment anxiety, but …

Special education in the public-school setting is designed to support students with disabilities by providing them specially designed instruction to meet their unique needs. This cannot be achieved without special education teachers who undergo specialized training to enable students with a disability to reach their maximum potential. Special education teachers' job duties differ greatly from that of a general education teacher, and they require specialized supports from their administrators. This qualitative study was designed for three purposes: (a) to understand the current teacher evaluation system along with the state and local policies from which the evaluation system is created; (b) to define the unique roles and responsibilities of the special education teacher that the current evaluation process may be failing to identify; and (c) to give special education teachers a voice to describe their experiences with the current teacher evaluation system. A document review of the current Texas Teacher Evaluation and Support System (T-TESS) evaluation rubric and of current state and local teacher evaluation policies preceded focus groups of high school special education teachers from three special education settings: inclusion, self-contained, and resource. Findings showed that teachers across all three settings agreed that T-TESS is not a true reflection of …

Student loan debt continues to be an issue in the U.S., with potential long-term effects on loan repayment and potential wealth accumulation. In particular, minorities face barriers in the educational system and accruing wealth. Hispanics occupy a middling position in the U.S. racial hierarchy. Using the National Longitudinal Survey of Youth 1997 geocode data, in this study I examined how Hispanic-White differences in student debt change over time and how student debt influences wealth. In addition, I accounted for immigration status via parents' nativity status to investigate debt burdens and subsequent wealth for these respondents. I used hierarchical linear growth models to examine debt growth over time and linear decomposition to examine Hispanic-White differences in wealth accumulation and the impact of student debt on these differences. While findings were largely statistically insignificant, I found that Hispanics tended to start with less debt than their White counterparts and that student debt initially grew for both groups. However, White respondents pay off their debt more quickly than Hispanics. In addition, I found that the wealth gap between White and Hispanic respondents grew significantly between the ages of 20 and 35. While Hispanics tended to start with less debt, my findings suggest that …

The COVID-19 pandemic is a global traumatic stressor affecting millions of individuals worldwide. Traumatic events often cause significant resource loss and negatively affect mental health and emotional well-being. In the wake of trauma, many people draw on religious or spiritual faith to cope with adversity and suffering. One construct that has received increased attention within the field of religious/spiritual coping is spiritual fortitude (SF). SF refers to the one's ability to consistently draw on spiritual resources to transcend negative emotions in the face of stressors. In this study, I recruited 255 participants who had lived during the COVID-19 pandemic. Participants completed measures of resource loss, religious/spiritual struggles, SF, religious commitment, depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms. The overall results suggested participants utilized a wide range of coping strategies (e.g., religious/spiritual, social, health practice) during the COVID-19 pandemic. Both resource loss and religious/spiritual struggles were positively associated with mental distress. SF buffered the deleterious relationship between resource loss and mental distress. Specifically, for individuals high in SF, the relationship between resource loss and mental distress was weaker than for individuals low in SF.

This study used an archival data set of 26 healthy adult immigrants from a sub-Saharan African country to the United States (Mage 39.0, SD = 11.36; Meducation 16.33, SD = 2.88; 40.7% male). Additional archival data was used for 32 healthy African American adults (Mage 34.06, SD = 11.18; Meducation 16.16, SD = 2.49; 53.1% male). A bivariate correlation indicated that acculturation to African culture, as measured by the mBIQ (M 49.29, SD = 8.66), was significantly positively correlated with ethnicity, r = .632, p = .000, ηp2 = 0.399. Two-way ANOVAs revealed that African Americans were able to name more animals than African immigrants (F(1, 54) = 4.82, p = 0.32, ηp2 = 0.82) and exhibited greater organizational skills during a task of cognitive set shifting and problem solving than African immigrants, regardless of level of acculturation (F(1, 54) = 4.47, p =.039, ηp2 = 0.078). In contrast, African immigrants scored higher than African Americans on indigenous fruit (F(1, 54) = 7.60, p =.008, ηp2 = 0.123) and object naming (F(1, 54) = 5.59, p =.022, ηp2 = 0.094). Results of the study concluded that there are small variance effects in language tasks as well as strategy-based approaches to …

On January 30, 2020, the World Health Organization (WHO) declared the outbreak of the novel coronavirus (COVID-19) a public health emergency of international concern. In March 2020, the United States government imposed impactful safety and confinement measures issued by the Centers for Disease Control and Prevention (CDC) all over the country to prevent community transmission of COVID-19. Institutions of higher education rapidly transitioned to online learning and eliminated in-person engagements in the spring of 2020 as a result of the COVID-19 outbreak. The National Collegiate Athletic Association (NCAA) followed a similar trajectory by shutting down all athletic activities due to the global pandemic. While college students in general notably experienced increased pandemic related distress and mental health concerns (e.g., depression, anxiety) during the early stages of the global pandemic, the disruption of collegiate sport competitions and seasons uniquely and significantly impacted collegiate student athletes and their overall well-being. In this qualitative study, I sought to document and understand the narrative of Black student athletes' experiences of stress and coping during the first two months of the COVID-19 global pandemic and cancellation of collegiate sports. Through reflexive thematic analysis, I found that psychosocial resources such as avoidance, acceptance, mindful self-compassion, health …

Since at least the 1960s, federal and state policymakers have debated how best to hold public schools accountable for producing graduates who are prepared to fully participate in our democratic society. Since that time, reform efforts have led to Texas' current test-based A-F accountability system. This qualitative case study explored how one Texas school district worked to design and implement an alternative accountability system. A community-based accountability system (CBAS) is created in collaboration with local stakeholders and uses locally developed goals and multiple achievement measures to report student and school performance. A zone of mediation theoretical framework was used to evaluate how the studied district assessed and addressed the community's norms, values, priorities, and goals for public schools. Data were drawn from an analysis of relevant documents, five individual district leader interviews, and a parent and/or community member focus group. These data were analyzed using a combination of a priori and in vivo coding. The six themes that emerged from this analysis were: (a) dissatisfaction with A-F accountability, (b) developing an alternative accountability, (c) collaboration with like-minded districts and leaders, (d) engagement with internal stakeholders; (e) engagement with external stakeholders, and (f) assessing community values and goals for public education. …

The purpose of this dissertation is to introduce Le Temps Déformé for solo flute, percussion, and strings, composed by Korean American composer Texu Kim (b. 1980) in 2017. The dissertation includes an analysis of the work and its background, to show that it represents a significant expansion of the concerto repertoire for solo flute and to help performers interpret it. This piece of writing should also contribute to the available sources about the composer Texu Kim, given that it is the first dissertation about him or his work. This piece should be appropriate for flutists who are seeking to perform a new piece with orchestra. Although hundreds of concertos have been written for solo flute and orchestra or string orchestra, Kim uses the unusual instrumentation of strings and percussion (drum and triangle) without woodwinds and brass. In a program note, the composer mentions that he made use of Korean traditional music, Sujecheon, which has similar instrumentation. The note also discusses he transformed and interpreted Korean traditional music to create a new interaction with Western music.

The expansionist agenda of the Polk administration culminated in the War with Mexico. The capture of Mexico City in September 1847 left the United States Army with the unprecedented task of occupying an enemy capital for an extended period. After the initial theaters of operation proved unable to secure a peace, Maj. Gen. Winfield Scott commenced a campaign to take central Mexico including the capital city. In March 1847, an army of 11,000 soldiers under Scott landed at Vera Cruz. In six months, Scott's army marched over 250 miles and won five major battles. In mid-September, Scott took Mexico City. Throughout the campaign, Scott attempted to implement a pacification plan in an effort to prompt Mexico to open peace negotiations. Concern for his army weighed heavily on him as he faced unprecedented challenges in occupying Mexico City after its capture. The United States simply had almost no experience in the ramifications of fighting a foreign war, other than a few brief small-scale incursions onto foreign soil at Tripoli in 1805 and in British Canada. The difficulties that arose for Scott from the situation in Mexico were frustrating. Scott pacification plan used conciliation, coercion, and force on Mexico's army and people …

Violence and aggression continue to be both public health and economic concerns. The field of violence prediction has undergone a series of changes in an attempt to best assess risk including using unstructured clinical judgment, actuarial measures, and structured professional judgment. Although prediction has become more accurate with improved measures, a new generation has recently emerged with an emphasis on understanding violence, as opposed to merely predicting it, to shift the focus towards violence prevention. In addition to the creation of measures, researchers have sought to identify specific risk factors for aggression and violence including static and dynamic risk factors. Despite research demonstrating associations between neuropsychological and social-cognitive factors, violence risk measures continue to omit these variables. The current study developed a multi-faceted, theoretical model of aggression including social-cognitive, neuropsychological, personality, and psychiatric factors. A community, male sample (N = 1,192) collected through Amazon's MTurk responded to a series of self-report measures and neuropsychological tasks. Utilizing structural equation modeling (SEM), I created a model predicting aggression. Several important paths were significant including from entity theory to aggression, mediated by hostile attribution bias, schizotypy to aggression, mediated by both hostile attribution bias and disinhibition, substance use to aggression mediated by disinhibition, …

The purpose of this research is to measure the social shifts that take place in a home where artificial intelligent (AI) devices like Echo Dot and Google Home are fully integrated into their everyday life. Research is currently limited, being that the widespread use of these devices is roughly seven years old. Three main outcomes of this study were related to how often Alexa is being used in homes to solve everyday problems, the lack of overall privacy and security concerns users had, and the level of integration into the home as a member of the family. Some limitations and challenges are my ability to compare the households before and after installing these devices in the home; pinpointing when and where the device is used (i.e., room placement); collecting data on whether the device is used often or sparingly; and the depth of interactions these families actually have with the device on a whole. The broader implications behind the increased integration of AI devices is centered around health, labor, social inequality and ethics.

Since the creation of the first all-state vocal jazz ensemble in 1978, similar ensembles have been established in roughly half of the United States. This paper contains historical summaries of the creation of all-state vocal jazz ensembles in nineteen of those states, primarily as recounted via interviews with those ensembles' founders. Each semi-structured interview was conducted over video conference or phone and lasted approximately one hour; resulting interview data was analyzed using qualitative methods. During the creation of each ensemble the respective founders needed to secure the support of a host organization, determine where and when to convene, and decide how to address auditions, sound reinforcement, rhythm sections, and funding. The diversity of solutions to these shared challenges reflects the diverse priorities of each founder as well as the unique conditions in which each all-state vocal jazz ensemble was established. However, several elements were common across these stories, including the influence of existing festivals and all-state ensembles, and tensions within the choral education community regarding the value of the vocal jazz idiom relative to traditional choirs, show choirs, and other vocal ensembles. In a few cases, established all-state vocal jazz ensembles were discontinued; these stories further illustrate the challenges such …

This study investigated personalized adaptive learning, teacher education, and self-efficacy to determine if personalized adaptive teacher education can increase self-efficacy. It is suggested that teachers with higher self-efficacy tend to stay in the teaching profession longer. Chapters 2 and 3 are literature reviews on personalizing adaptive learning to determine what common components are used in personalized adaptive learning systems to get a clear understanding of what previous literature suggests building this study on it. Chapter 4 investigates the data collected from 385 teachers to understand better what teachers report on factors that increase their self-efficacy. As a result, it was found that teachers' self-efficacy increases with more training, support, and resources. In chapter 5, a framework was developed based on previous findings, with components of personalized adaptive learning to provide support/help at the right time for teachers to increase their self-efficacy. An empirical study was conducted to validate this framework, where the framework was used as a guide to personalize and adapt summer teacher preservice training and survey teachers on their self-efficacy before and after the training to see its impact on teachers' self-efficacy. However, since summer preservice training was virtual, the framework could not be implemented fully, as we …

Music binder's volumes, or collections of sheet music typically bound by women in the nineteenth century, constitute an informative and underutilized set of historical artifacts. Each binder's volume can be viewed as a Spotify playlist frozen in time. An individual volume contains more than just the volume's individual pieces; it also holds the marginalia, the choices women made on what to include in a binder, and information on where and how music was produced. This dissertation examines music binder's volumes quantitatively, processing information found in binder's volumes by using the MARC and other cataloguing data to construct a relational database. I engage with broad questions of music publishing and consumption and provide a method to contextualize qualitative results on a larger scale. In doing so, I make two distinct contributions to music research and the digital humanities. First, this project offers a clear path for engaging with music binder's volumes and material history of nineteenth-century America in ways that scholars have rarely engaged in prior to this point. I highlight how data analysis provides new framings for binder's volumes and for sheet music consumption both at the song-level and at larger levels of the data. Second, and more broadly, this …

Saudi Arabia introduced the VAT in 2018 in response to the nation's structural budget deficit caused, in large measure, by its dependence on revenue from oil and natural gas production. Initially the tax rate was 5 percent, but in July 2020 the rate was tripled to 15 percent. This dissertation examine the effect of the introduction of a value-added tax (VAT) on governance in Saudi Arabia. Specifically, we explore how the VAT's introduction has altered the Saudi bureaucracy, both its responsiveness and representativeness, and what is VAT effect on growth in GDP, public unemployment, and changes in national budget. The data used to analyze these research questions are collected from several sources including the Saudi General Authority for Statistics, Saudi Ministry of Finance, and World Bank. Different methods of analysis were used such as ordinary least squares, difference in differences, and least squares dummy variables to answer the research questions. The study found that VAT is associated with an increase in GDP per capita, and VAT was negatively associated with total debt per capita, deficit per capita, and non-Saudi unemployment. In addition, government spending did change after the introduction of VAT to internal development more than external focus. Finally, VAT …
