The Creation of a Performance Edition of Gustav Mahler's Lieder Und Gesänge Aus Der Jungendzeit and Its Role in Bass Tuba Pedagogy (open access)

The Creation of a Performance Edition of Gustav Mahler's Lieder Und Gesänge Aus Der Jungendzeit and Its Role in Bass Tuba Pedagogy

When the tubist is first introduced to the bass tuba, Mahler's songs can be used as effective solo material. Through transcription, practice, and performance of art songs, novice bass tubists focus primarily on fundamental musical components such as tone quality, intonation, breathing, and musicianship. By identifying deficiencies in the current solo repertoire as related to the early stages of development on the bass tuba, I intend to address the need for more solo works through the transcription and performance of Mahler's Lieder und Gesänge aus der Jugendzeit.

Investigating the Effects of Polypharmacy Among Elderly Patients with Diabetes on Glycemic Control and Clinical Outcomes in Home Health Care (open access)

Investigating the Effects of Polypharmacy Among Elderly Patients with Diabetes on Glycemic Control and Clinical Outcomes in Home Health Care

The focus of this research study is glycemic control in the presence of multiple morbidities and polypharmacy in homebound individuals with Type 2 diabetes aged 65 years and older. The research method is a quantitative retrospective cohort study of discharged patients of a nonprofit community-based home health agency from January 1, 2010, to December 31, 2011, using OASIS data. Glycemic control is assessed using the hA1C laboratory test following the recommendation of the American Diabetes Association. The study documents a moderate significant association between glycemic control, polypharmacy and comorbid conditions, indicating that homebound individuals with Type 2 diabetes aged 65 years and older are less likely to have optimal glycemic control in the presence of multiple morbidities and polypharmacy. There continues to be a need for scientific research in this population cohort; and the dose-response association between antidiabetic therapy interventions designed to lower blood glucose levels in the presence of chronic disease and polypharmacy.

Impacts of Postmodernity Factors on the Association Between Maternal Distress and Children's Delinquency Among Low-income Families (open access)

Impacts of Postmodernity Factors on the Association Between Maternal Distress and Children's Delinquency Among Low-income Families

This study investigates the effects of postmodern factors on the relationship between maternal distress and children's delinquency. It seeks to understand the factors associated with distress levels of mothers whose children exhibit delinquency in order to potentially decrease the cost associated with mental health problems especially in mothers. Another goal of this study is to contribute to the sociological analysis of mental health problems which seem to be the reserved domain of the discipline of psychology and related subfields. The data came from the third wave of the 3-city study with N = 1835. The ages of the children range from 5 to 18 years old. The analysis of the data using regression analysis suggests children's delinquency significantly affects maternal distress in mothers. The study also indicates postmodernity factors did not moderate the association between maternal distress and children's delinquency. However, postmodern factors have significant, separate, and direct effects on maternal distress. For example, employment and religion have positive influences on maternal distress. The research points toward weakness in the postmodern perspective. It also underlines the importance of a sociological approach to the assessment and treatment of distress problems among mothers with low-income. Agencies working with low-income families should integrate …

Impact of Video Presentation Features on Instructional Achievement and Intrinsic Motivation in Secondary School Learners (open access)

Impact of Video Presentation Features on Instructional Achievement and Intrinsic Motivation in Secondary School Learners

This study analyzed instructional achievement and intrinsic motivation among 21st century secondary students utilizing a video lecture incorporating both student reaction cutaway images and immediate content interaction within the lecture. Respondents (n = 155) were from multiple classes and grade levels at a suburban Texas high school. Four groups of students viewed the identical lecture with differing video and content interaction treatments. Students responded to a pretest/posttest survey to assess academic achievement in addition to an intrinsic motivation instrument to assess student interest. Group one (the control group) viewed the 12 minute lecture without enhancement. A second group viewed the identical lecture with student reaction shots inserted in the video. Another group viewed the lecture with content question intervention inserted into the video. The final group saw the lecture with the student reaction shots and content question intervention combined in the video. A repeated measures multivariate analysis of variance (MANOVA) was used to compare results from a 14 item pretest/posttest. Combined, the groups showed no significance (p = .069) indicating no associations were identified by the experiment. Although no association was identified, this may be a reflection of the generic nature of the video lecture and the lack of association …

The Useful Arts

This creative nonfiction dissertation is a series of braided narratives that chronicle the author's career as a trombonist in the John Smith Ensemble. As an amateur trombonist, the author is shocked to be hired as a professional musician for an orchestra that plays on PBS and at Carnegie Hall. She quickly realizes, however, that the job requires her to play the trombone quietly in front of an unplugged microphone while a CD recording of another, more talented trombonist is blasted out toward an unknowing audience. The job also requires the author to tour around America. The scenes of from this tour are braided with scenes wherein she reflects on her life as a professional fake musician and her past failed attempts at getting a job.

José Antonio Gómez´s Versos Para Órgano (Section I): a Practical Guide for Performance (open access)

José Antonio Gómez´s Versos Para Órgano (Section I): a Practical Guide for Performance

José Antonio Gómez is an important figure in Mexican music history and his works are considered representative of the beginning of Mexico´s Independent era. Some musicians are familiar with Gómez´s choral output but his organ music is rarely considered. Due to the lack of an edition of Gómez´s Versets for Organ, a practical guide was found needed to aid its performance. This study is based on performance, analysis, and direct work on the only known source for it. The first chapter, Introduction, presents the argument for an edited version of the first part of the manuscript as a performance guide. The second provides biographical information on the composer. The third chapter discusses the background for the original performance of the Versets for Organ. Chapter 4 provides performance considerations for the works. The edition of the manuscript is included in chapter 5.

Criticality in Cooperative Systems (open access)

Criticality in Cooperative Systems

Cooperative behavior arises from the interactions of single units that globally produce a complex dynamics in which the system acts as a whole. As an archetype I refer to a flock of birds. As a result of cooperation the whole flock gets special abilities that the single individuals would not have if they were alone. This research work led to the discovery that the function of a flock, and more in general, that of cooperative systems, surprisingly rests on the occurrence of organizational collapses. In this study, I used cooperative systems based on self-propelled particle models (the flock models) which have been proved to be virtually equivalent to sociological network models mimicking the decision making processes (the decision making model). The critical region is an intermediate condition between a highly disordered state and a strong ordered one. At criticality the waiting times distribution density between two consecutive collapses shows an inverse power law form with an anomalous statistical behavior. The scientific evidences are based on measures of information theory, correlation in time and space, and fluctuation statistical analysis. In order to prove the benefit for a system to live at criticality, I made a flock system interact with another similar …

Leader Developmental Readiness of Generation Y in the Training Industry (open access)

Leader Developmental Readiness of Generation Y in the Training Industry

Members of Generation Y in the training and development industry will be required to assume leadership roles as Baby Boomers retire, yet little empirical research exists regarding how best to prepare them for leadership. The purpose of this study was to examine differences in leader developmental readiness between generational cohorts in the training industry, specifically Baby Boomers, Generation X, and Generation Y. Leader developmental readiness provided a definition of developmental readiness for leaders using the five constructs (learning goal orientation, developmental efficacy, self-awareness, leader complexity, and metacognitive ability). A volunteer sample was compiled from members of the ASTD National LinkedIN group (n = 636). Results were analyzed using structured means analysis with maximum likelihood (ML) estimation. Generational cohorts demonstrated differences in leader developmental readiness. Baby Boomers indicated statistically and practically higher metacognitive ability and developmental efficacy than Generation Y. Results demonstrated statistically and practically higher leader complexity in Generation Y and both Generation X and Baby Boomers. These results should inform leader development practitioners as they continue to use existing methods in preparing the different generations for leader development interventions while pointing to possible needs to increase the metacognitive ability and developmental efficacy in Generation Y and ensure accurate perception …

Real Analyticity of Hausdorff Dimension of Disconnected Julia Sets of Cubic Parabolic Polynomials (open access)

Real Analyticity of Hausdorff Dimension of Disconnected Julia Sets of Cubic Parabolic Polynomials

Consider a family of cubic parabolic polynomials given by for non-zero complex parameters such that for each the polynomial is a parabolic polynomial, that is, the polynomial has a parabolic fixed point and the Julia set of , denoted by , does not contain any critical points of . We also assumed that for each , one finite critical point of the polynomial escapes to the super-attracting fixed point infinity. So, the Julia sets are disconnected. The concern about the family is that the members of this family are generally not even bi-Lipschitz conjugate on their Julia sets. We have proved that the parameter set is open and contains a deleted neighborhood of the origin 0. Our main result is that the Hausdorff dimension function defined by is real analytic. To prove this we have constructed a holomorphic family of holomorphic parabolic graph directed Markov systems whose limit sets coincide with the Julia sets of polynomials up to a countable set, and hence have the same Hausdorff dimension. Then we associate to this holomorphic family of holomorphic parabolic graph directed Markov systems an analytic family, call it , of conformal graph directed Markov systems with infinite number of edges in …

British Labour Government Policy in Iraq, 1945-1950 (open access)

British Labour Government Policy in Iraq, 1945-1950

Britain during the Labour government's administration took a major step toward developing Iraq primarily due to the decision of Ernest Bevin, the Foreign Minister, to start a new British policy toward the Iraqi regimes that would increase the British influence in the area. This led to Bevin's strategy of depending on guiding the Iraqi regime to make economic and political reforms that would lead to social justice.

Predictors of Quality of Life (Qol): Comparing Baby Boomers, Older Adults, and Younger Adults Using Data From the 2010 National Health Interview Survey (open access)

Predictors of Quality of Life (Qol): Comparing Baby Boomers, Older Adults, and Younger Adults Using Data From the 2010 National Health Interview Survey

The purpose of this study was to identify factors that predict quality of life (QOL) for aging adults and to examine and compare Baby Boomers', Older Adults' and Younger Adults' responses to the 2010 National Health Interview Survey/QOL Functioning and Disability. Significant findings included several significant values based on the multivariate regression to estimate a model to predict QOL. In particular, being male, four ethnicities other than white, being older than Boomer, age in 10 years, the Functional Difficulty Index, the Functional Limitation Index scores, chronic heart disease, asthma, and arthritis all had significant p values. Adults with chronic heart disease, asthma, or arthritis scored lower on the QOL index, but cancer, stroke, or diabetes were not associated with the QOL index. Two hypotheses had strong support. Lower scores on both the Functional Difficulty Index and the Functional Limitation Index yielded lower QOL scores. Further research recommendations include establishing reliability and validity of the QOL index; running additional regressions for demographics (ethnicity, marital status, etc.) to predict possible combinations of variables predicting QOL or barriers to QOL; and investigating the viability of incorporating the QOL index into an electronic medical record (EMR) dashboard parameter to serve as a screening mechanism …

Development of a Laponite Pluronic Composite for Foaming Applications (open access)

Development of a Laponite Pluronic Composite for Foaming Applications

The focus of the following research was to provide an optimized particle stabilized foam of Laponite and Pluronic L62 in water by understanding (1) the Laponite-Pluronic interactions and properties for improved performance in a particle stabilized foam and (2) the interfacial properties between air and the Laponite-Pluronic complex. These studies were conducted using both bulk and interfacial rheology, XRD, sessile droplet, TGA and UV-vis. Two novel and simple techniques, lamella break point and capillary breakup extensional rheometry, were used to both understand the Laponite Pluronic L62 interaction and determine a different mechanism for foaming properties. Bulk rheological properties identified an optimal Laponite concentration of 2% with Pluronic L62 ranging from 2.5% and 6.5%, due to the ease of flow for the dispersion. The Pluronic L62 was observed to enhance the Laponite bulk rheological properties in solution. Additionally TGA showed a similar trend in thermal resistance to water with both addition of Laponite and Pluronic L62. XRD demonstrated that 0.25% Pluronic intercalated into Laponite from dried 2% Laponite films. XRD demonstrated that the Laponite matrix was saturated at 1% Pluronic L62. UV-vis demonstrated that a monolayer of Pluronic L62 is observed up to 0.65% Pluronic L62 onto Laponite. Interfacial rheology showed …

Between Comancheros and Comanchería: a History of Fort Bascom, New Mexico (open access)

Between Comancheros and Comanchería: a History of Fort Bascom, New Mexico

In 1863, Fort Bascom was built along the Canadian River in the Eroded Plains of Territorial New Mexico. Its unique location placed it between the Comanches of Texas and the Comancheros of the Sangre de Cristo Mountains. This post was situated within Comanchería during the height of the United States Army's war against the Southern Plains Indians, yet it has garnered little attention. This study broadens the scholarly understanding of how the United States Army gained control of the Southwest by examining the role Fort Bascom played in this mission. This includes an exploration of the Canadian River Valley environment, an examination of the economic relationship that existed between the Southern Plains Indians and the mountain people of New Mexico, and an account of the daily life of soldiers posted to Fort Bascom. This dissertation thus provides an environmental and cultural history of the Canadian River Valley in New Mexico, a social history of the men stationed at Fort Bascom, and proof that the post played a key role in the Army's efforts to gain control of the Southern Plains Indians. This study argues that Fort Bascom should be recognized as Texas' northern-most frontier fort. Its men were closer to …

Predictors of College Readiness: an Analysis of the Student Readiness Inventory

The purpose of this study was to better predict how a first semester college freshman becomes prepared for college. the theoretical framework guiding this study is Vrooms’ expectancy theory, motivation plays a key role in success. This study used a hierarchical multiple regression model. the independent variables of interest included high school percentile class rank, composite ACT scores, composite SAT scores, and the 10 themes as measured by the Student Readiness Inventory (SRI) to address two research questions: What are the psychosocial factors identified by the SRI are most relevant in predicting college success? What conventional academic indicators are most relevant in predicting college success? the sample size for this study was 5279 (n), including a stratified random sample of first semester college freshman enrolled in credit bearing courses; these participants were deemed college ready by the university. Academic Discipline accounted for 4.2% of the variance in first semester college GPA, General Determination accounted for 1.7% of the variance, and the remaining psychosocial factors of the SRI accounted for less than 1% of the variance. High school percentile class rank accounted for 10.7% of the variance, composite ACT accounted for 5.9% of the variance, and composite SAT accounted for 5.6% …

Equivalence Classes of Subquotients of Pseudodifferential Operator Modules on the Line (open access)

Equivalence Classes of Subquotients of Pseudodifferential Operator Modules on the Line

Certain subquotients of Vec(R)-modules of pseudodifferential operators from one tensor density module to another are categorized, giving necessary and sufficient conditions under which two such subquotients are equivalent as Vec(R)-representations. These subquotients split under the projective subalgebra, a copy of ????2, when the members of their composition series have distinct Casimir eigenvalues. Results were obtained using the explicit description of the action of Vec(R) with respect to this splitting. In the length five case, the equivalence classes of the subquotients are determined by two invariants. In an appropriate coordinate system, the level curves of one of these invariants are a pencil of conics, and those of the other are a pencil of cubics.

Lind, James Meyer the Trumpet Concertos of Anthony Plog: a Performer’s Guide (open access)

Lind, James Meyer the Trumpet Concertos of Anthony Plog: a Performer’s Guide

Anthony Plog (b. 1947) has contributed several notable works for brass instruments. He is known for writing extremely technically challenging works that contain angular melodies, fast rhythms and a large degree of chromaticism. Though his music is difficult, it also conveys intense emotions. His music for trumpet, specifically Concerto no. 1 for Trumpet, Brass Ensemble and Percussion and Concerto no. 2 for Trumpet and Orchestra, represents a zenith in his compositional development. This dissertation examines Concerto no. 1 and Concerto no. 2 from a performer’s perspective to better understand the stylistic characteristics and challenges encountered in his music. Each concerto is examined in terms of rhythmic structure, intervallic structure, thematic material, motivic material and form.
