Building an Effective Piano Technique while Avoiding Injury: A Comparison of the Exercises in Alfred Cortot's "Rational Principles of Pianoforte Technique" and Carl Tausig's "Daily Studies for the Pianoforte"

Description: It is the teacher's responsibility to guide students in building an effective and injury-free piano technique. Improper technique, poor training and bad posture at the instrument all may cause problems such as lack of muscle control, weakness, or tension in the hands. Many teachers are interested in finding information about specific exercises dealing with finger strengthening, stretching, and warm-up strategies, as well as guidelines for safe practicing. It is therefore important for both teachers and students to understand how to build a technique from the earliest years of instruction. Carl Tausig (1841-1871) and Alfred Cortot (1877-1962) both contributed to the development of piano technique by writing books that include a significant number of exercises and excerpts. Their books incorporate detailed instructions on how to play each exercise effectively and without fatigue. Subsequently, Heinrich Ehrlich (1822-1899) collected and systematically arranged Tausig's notes, complementing them with detailed information on how to play Tausig's exercises without causing injury. This dissertation compares and contrasts the exercises found in Alfred Cortot's book, Rational Principles of Pianoforte Technique, and Carl Tausig's book, Daily Studies for the Pianoforte. The latter is based on the practical guidebook, How to Practise on the Piano: Reflections and Suggestions, written by Heinrich Ehrlich. Included in this study are references to the performing arts medical literature dealing with pianists' injuries. By comparing two different historical piano methods and considering their effectiveness in light of modern medical performance research, this dissertation aims to help teachers to determine which methods might be better for students to build a solid piano technique without injuring themselves.

Leader-Follower Model and Impact of Mobility on Consensus Building

Description: Wireless sensor networks are an indispensable tool in this highly connected world. WSNs have been the focus of research efforts in areas of communication, electronics and control for many years. Advancements in the fields of MEMS, RF and digital circuit technology has led to the development of low cost and extremely power efficient smart sensors. This has led to the need of a fast, reliable and inexpensive method of consensus building for these sensor networks. Basic concepts of graph theory and consensus building are explained in this thesis. This thesis reviews the models and strategies for consensus building present in the literature. The shortcomings of these models are explained through examples and a leader-follower model based consensus building strategy is presented. Algorithm to convert any graph into a bipartite graph by edge removal and a strategy to select effective leaders based on a weighted combination of node centrality, ratio of leaders to the total number of nodes and presence of leaf nodes in the group is presented in this thesis. Proposed leader-follower model is compared against classic models for consensus building are compared and proven to be better. Mobility is studied using deterministic and random mobility models to show the improvement in convergence rate of the network. It is shown that mobility can turn any disconnected network into a connected network, which is able to reach consensus.

Miranda Comprehension and Reasoning: An Investigation of Miranda Abilities in Adult Inpatients

Description: Nearly 700,000 suspects with mental disorders are arrested and Mirandized each year. The current study systematically examined the effects of cognitive deficits and psychological symptoms on both Miranda comprehension and reasoning. The current sample was comprised of 85 adult psychiatric inpatients recruited from University Behavioral Health (UBH), a private psychiatric hospital in North Texas. Unexpectedly, most inpatients demonstrated pervasive deficits in their immediate recall of a representative Miranda warning, omitting approximately four-fifths of its content. In addition, the majority of inpatients evidenced damaging errors in their reasoning about waiver decisions. As a result, 64.7% waived and subsequently confessed after only a 3-5 minute interrogation. Interestingly, impaired verbal ability but not the severity of their symptoms predicted greater deficits in Miranda comprehension.

Study Abroad and Student-Athlete Choice

Description: The focus of this case study was a study abroad program for student-athletes at a high academically achieving, small liberal arts college in the mid-west region of the United States. The program is designed to maintain a culture of internationalism and multiculturalism by exposing as many student-athletes as possible to study abroad. I reviewed literature to extract an appropriate theoretical framework along with variables that aligned with the purpose of the study; structural and organizational characteristics of the institution, student's background and pre-college traits, interaction with agents of socialization and institutional environment, and quality of effort. I used the semi-structured interview process to interview 9 senior student-athletes (3 female, 6 male; 7 White, 1 African American/White, 1 Chilean/White) who participated in study abroad during the 2015-2016 academic school year at the researched institution and to interview 5 administrators who facilitate the athletic department at the institution. I found that certain critical elements emerged as necessary to create and maintain a study abroad program geared specifically to the needs of the student-athlete population. I also found strong implications for adaptable elements that could generate opportunities for student-athletes to study abroad at a higher rate. These elements serve as a recommended framework and set of initial guidelines for student-athletes and athletic departments nationwide.

Investigation of Spray Cooling Schemes for Dynamic Thermal Management

Description: This study aims to investigate variable flow and intermittent flow spray cooling characteristics for efficiency improvement in active two-phase thermal management systems. Variable flow spray cooling scheme requires control of pump input voltage (or speed), while intermittent flow spray cooling scheme requires control of solenoid valve duty cycle and frequency. Several testing scenarios representing dynamic heat load conditions are implemented to characterize the overall performance of variable flow and intermittent flow spray cooling cases in comparison with the reference, steady flow spray cooling case with constant flowrate, continuous spray cooling. Tests are conducted on a small-scale, closed loop spray cooling system featuring a pressure atomized spray nozzle. HFE-7100 dielectric liquid is selected as the working fluid. Two types of test samples are prepared on 10 mm x 10 mm x 2 mm copper substrates with matching size thick film resistors attached onto the opposite side, to generate heat and simulate high heat flux electronic devices. The test samples include: (i) plain, smooth surface, and (ii) microporous surface featuring 100 μm thick copper-based coating prepared by dual stage electroplating technique. Experimental conditions involve HFE-7100 at atmospheric pressure and 30°C and ~10°C subcooling. Steady flow spray cooling tests are conducted at flow rates of 2 - 5 ml/cm².s, by controlling the heat flux in increasing steps, and recording the corresponding steady-state temperatures to obtain cooling curves in the form of surface superheat vs. heat flux. Variable flow and intermittent flow spray cooling tests are done at selected flowrate and subcooling conditions to investigate the effects of dynamic flow conditions on maintaining the target surface temperatures defined based on reference steady flow spray cooling performance.

Automated GUI Tests Generation for Android Apps Using Q-learning

Description: Mobile applications are growing in popularity and pose new problems in the area of software testing. In particular, mobile applications heavily depend upon user interactions and a dynamically changing environment of system events. In this thesis, we focus on user-driven events and use Q-learning, a reinforcement machine learning algorithm, to generate tests for Android applications under test (AUT). We implement a framework that automates the generation of GUI test cases by using our Q-learning approach and compare it to a uniform random (UR) implementation. A novel feature of our approach is that we generate user-driven event sequences through the GUI, without the source code or the model of the AUT. Hence, considerable amount of cost and time are saved by avoiding the need for model generation for generating the tests. Our results show that the systematic path exploration used by Q-learning results in higher average code coverage in comparison to the uniform random approach.

Probabilistic Analysis of Contracting Ebola Virus Using Contextual Intelligence

Description: The outbreak of the Ebola virus was declared a Public Health Emergency of International Concern by the World Health Organisation (WHO). Due to the complex nature of the outbreak, the Centers for Disease Control and Prevention (CDC) had created interim guidance for monitoring people potentially exposed to Ebola and for evaluating their intended travel and restricting the movements of carriers when needed. Tools to evaluate the risk of individuals and groups of individuals contracting the disease could mitigate the growing anxiety and fear. The goal is to understand and analyze the nature of risk an individual would face when he/she comes in contact with a carrier. This thesis presents a tool that makes use of contextual data intelligence to predict the risk factor of individuals who come in contact with the carrier.

Extending the Apprenticeship through Informal Learning on Facebook: An Interpretative Phenomenological Analysis of the Lived Experiences of Music Faculty

Description: Facebook studio groups/pages are commonly used by applied music faculty to communicate with current students, recruit new students, share students' activities, and promote faculty members' professional performances and academic endeavors. However, the blurred lines between academic, professional performance, and social activities in the field have led to a wide variety of approaches to Facebook use by music faculty. This dissertation documents the first generation of music faculty social media users and investigates the beliefs, intent, and lived experiences of music faculty who use Facebook studio groups/pages to communicate with their students. Four music faculty were interviewed and a semester's Facebook studio group/page data collected for each faculty member. Interviews and Facebook data were analyzed using Interpretative phenomenological analysis (IPA) to identify emergent, and ultimately super-ordinate, themes from the data. The three super-ordinate themes that emerged were: Impact of Social Media on Studio Teaching and Learning, Learning through Enculturation, and Faculty Lived Experiences with Facebook Studio Groups/Pages. Findings of the study included: faculty concerns about personal and professional risk; the observation that teaching and learning are occurring through these Facebook studio groups/pages by way of the process of enculturation, but without evidence of a Virtual Community of Practice; and, a multitude of group/page management practices developed in isolation that suggest a need for discussion/debate and training in the field to determine best practices for using Facebook studio groups/pages as an extension of the physical studio. Recommendations include training for music faculty that situates Facebook studio groups/pages within the enculturation process of students pursuing careers in music, music department development of guidelines for Facebook group/page creation and management based upon their institutions' rules and oversight procedures, and the sharing of exemplar Facebook studio groups/pages by professional music education organizations to encourage discussion of best practices for teaching and learning in informal environments.

Elucidation of Photoinduced Energy and Electron Transfer Mechanisms in Multimodular Artificial Photosynthetic Systems

Description: Multimodular designs of electron donor-acceptor systems are the ultimate strategy in fabricating antenna-reaction center mimics for artificial photosynthetic applications. The studied photosystems clearly demonstrated efficient energy transfer from the antenna system to the primary electron donor, and charge stabilization of the radical ion pair achieved with the utilization of secondary electron donors that permits either electron migration or hole transfer. Moreover, the molecular arrangement of the photoactive components also influences the route of energy and electron transfer as observed from the aluminum(III) porphyrin-based photosystems. Furthermore, modulation of the photophysical and electronic properties of these photoactive units were illustrated from the thio-aryl substitution of subphthalocyanines yielding red-shifted Q bands of the said chromophore; hence, regulating the rate of charge separation and recombination in the subphthalocyanine-fullerene conjugates. These multicomponent photosystems has the potential to absorb the entire UV-visible-NIR spectrum of the light energy allowing maximum light-harvesting capability. Furthermore, it permits charge stabilization of the radical ion pair enabling the utilization of the transferred electron/s to be used by water oxidizing and proton reducing catalysts in full-scale artificial photosynthetic apparatuses.

"Spectral Evidence"

Description: Spectral Evidence is a collection of poems that instigates a variety of omens, signs, divinations, and folktales to explore the concept of wish fulfillment. They arise in obedience to the compulsion to repeat past dramas brought on by failed love, the nostalgia of childhood, the damning legacy of language, the restriction of gender roles, death, etc. In order to quell these anxieties, the speaker looks beyond the self to both history and mythology, often invented mythologies as an attempt to control or recast the story-to give shape to the obscurities of life by creating a system of belief in order to forge meaning or confuse oneself into believing. In many ways this collection is all about belief or in wanting to believe. Through language, God is written into existence. God is the name of the blanket we put over the mystery to give it shape. Here, in this collection, God is an ant's egg. a cherry pit, a colony of white moths, a severed hand, the color red, a little bird. This collection explores these vehicles of meaning, the words that provide the shell of meaning, and the power of invention in hopes to gain control over what is deemed uncontrollable. While the speaker may be casting omens as "pre-ordained" entities outside of her power, it is her convictions in these signs that her own psychological and associative link between their meaning and their appearance that she conjures and creates because the existing systems of language, religion, and belief do not serve her. This creation is what is powerful. It is healing. It is birth. It is not involuntary wish fulfillment. It is the deliberative satisfaction of desire-on of the most insurrectionary acts a woman can execute.

Factors Affecting Faculty Acceptance and Use of Institutional Repositories in Thailand

Description: Institutional repositories have been introduced as an innovative and alternative technology for scholarly communication and have received considerable attention from scholars across disciplines and around the globe. While some universities in Thailand have developed and implemented institutional repositories for nearly a decade, knowledge of the acceptance and use of institutional repositories on the individual level in the country remains limited. As an insufficient knowledge of technology acceptance and adoption at the individual level is considered partially responsible for the underutilization of innovation or of information system implementation, this study seeks to uncover knowledge regarding the level of institutional repository acceptance and use. This study applied the unified theory of acceptance and use of technology (UTAUT) model and the model of faculty members' self-archiving behavior to investigate factors affecting faculty acceptance and use of university-based institutional repositories. The study employed a mixed methods approach involving a survey followed by semi-structured, one-to-one interview. This study confirms that the success of university-based institutional repositories depends not on a single factor but on multiple factors. The results of the study show that performance expectancy, social influence, and resistance to change were direct determinants of faculty members' intention to use institutional repositories. Additionally, behavioral intention and altruism were found to be the main determinants of actual usage behavior. The findings of this study imply that education in and promotion of open access and institutional repositories are essential and can play an important role in the adoption of institutional repositories. Finally, this study suggests that sustained dialogue and collaborative efforts among faculty members (as contributors and users), libraries/librarians (as institutional repository developers and managers), and other stakeholders within communities are essential for the adoption and success of university-based institutional repositories.

The Shrinking Opera Diva: The Impact of Sociocultural Changes upon the Casting of Women in the 20th and 21st Centuries

Description: For most of the twentieth century, opera singers were not beholden to the ideal physical standard of women dictated by popular culture, but rather focused on serving the music and perfecting their artistry. Unprecedented sociocultural changes throughout the twentieth century exposed the shifting ideals of each generation and how they were promoted through mass media and advertising. This thesis surveys the time period of the 1890s to the present day for the purpose of analyzing cultural trends, philosophies and technologies that shaped the century. Societal pressure to make the body a project and the focus of one's own intense attention now reflects back onto the opera stage where audience members expect to see what society has dictated to be an acceptable female form. Artistic and stage directors are influenced by society's decree that only thin is beautiful, imbedding into the mindset of the art form notions that now affect how female professional opera singers are depicted and even employed.

Smartphones and Tablets: Patterns of Usage among College Student Populations

Description: This study offers insight into students' use and desire to use mobile devices for educational purposes. I examined college students' mobile device usage on the basis of demographic factors including sex, age, ethnicity, class standing, mode of delivery, and socioeconomic status. This study also investigated factors that affect students' likelihood to use mobile devices for academic pursuits. I utilized data from the EDUCAUSE Center for Analysis and Research's (ECAR) 2015 Student Technology Survey. Of the 10,000 undergraduate respondents, 56% were female, 70% were between the ages of 18-24, 73% attended college full time and the breakdown of ethnicity included 59% Caucasian, 16% Hispanic, 13% African American, 8% Asian and 1% Native American. The results indicated that traditional aged students reportedly used smartphones more frequently, whereas non-traditional aged students reportedly used tablets more. Students most frequently reported using their devices in class to connect to the learning material. Institutional technology infrastructure and support were strong factors impacting students' use of smartphones. Results of this research can assist higher education faculty and administrators in devising comprehensive training and technology plans to support and encourage students' use of mobile devices for educational purposes.

Simplification and Octavation in Double Bass Performance: An Overview of Historical and Contemporary Practices

Description: Two important performance practices in the modern orchestral performance are discussed in this document: simplification and octavation. Due to the differing opinions and common practices which bass players have around these two performance practices, simplification and octavation have become two of the most complex issues faced by orchestral sections. The first part of the document will provide a brief history of simplification and octavation. The second part of the document will offer recommendation for double bass orchestral practice in the 21st century and examine key works of the bass repertoire in which simplification and octavation occur. The research and practice of leading pedagogues and major orchestral players and the solutions they have developed to reduce the discrepancy inherent within section playing will be discussed. This document will propose several empirical solutions to major excerpts in the bass repertoire, demonstrating how it is to achieve the most uniformed playing, and offer applicable and suggestive guidelines for contemporary orchestral double bass performers.

The Relationship between Judicial Independence and Ethnic Conflict

Description: The relationship between judicial independence and the levels of ethnic conflicts in developing countries has remained a significant research area due to increased cases of the conflicts with lack of judicial independence in the countries. Judicial independence is seen as an essential element of democracy in that an independent judiciary can act as an arbiter between different groups and institutions. The main aim of this study was to examine the relationship between judicial independence and ethnic conflicts empirically. Greater judicial independence should be associated with less ethnic conflict, because an independent court can serve as an arbiter for disputants, and thus lessen the likelihood of conflict. The study involved 128 developing countries over a 30-year period from 1981 to 2010 using secondary data sources and employing statistical methods to test the relationship between judicial independence and the levels of ethnic conflicts. Findings indicate that judicial independence has a statistically significant negative association with the levels of ethnic conflict. Therefore, this study recommends that the governments of developing countries should promote judicial independence as part of solutions for ethnic conflicts .

Multimodal Design for Secondary English Language Arts: A Portraiture Study

Description: Employing the research approach known as portraiture, this study investigated the varying ways in which three secondary English language arts teachers at a visual and performing arts high school conceptualized and designed multimodal literacy learning. Also studied were the ways in which their students responded to these designs; and in keeping with portraiture, attention went to the changes in the researcher's own understandings. This multi-case study and cross-case analysis built on prior multimodal literacy research in secondary education, but unlike previous studies, gave major attention to how teachers' conceptualization of multimodality and their own roles related to the designs that they produced. Since the school emphasized arts as well as academics, particular attention went to teachers' conceptions of, and designs for, arts-related multimodalities. Data for the portraits came from observations, teacher and student interviews, artifacts, and a researcher journal. Recursive analysis focused on repetitive refrains, resonant metaphors, and emergent themes, which provided data for "painting" the teachers' portraits in prose. Findings show the connections among teachers' beliefs, values, and the multimodal designs, which included images, movement, sound, classroom displays, and room arrangements. The three teachers took dramatically different approaches to multimodal designs as they created their productions of English language arts. Differences across teachers were related to their conceptions of multimodal design (i.e., for social activism, for expression, for edification) and to their conceptions of their roles as multimodal literacy designers (i.e., challenger, facilitator, channel). Students' responses to, and participation in, the multimodal activities also varied across classroom and teacher. The concluding discussion addresses the relation of arts integration to multimodal literacy education, the value of students' transmodal activity, and connections between multimodality and portraiture. The study illustrates the potential of portraiture for studies of multimodality as well as the potential of using multiple modes to "paint" portraits. Lawrence-Lightfoot, S., ...

The Relation of Sport Involvement and Gender to Fitness, Self-Efficacy, and Self-Concept in Middle School Students

Description: In the current study, the relation of the frequency of sport participation and gender to CRF, muscular strength and flexibility, body composition, physical activity self-efficacy, and physical self-concept in a sample of 629 sixth graders were examined. Because both physical activity and sport participation have been related to similar outcomes, activity through physical education was controlled by including only 6th graders who were part of a required school class. MANCOVA analyses demonstrated that sport involvement was significantly related to improvements in physical fitness (i.e., CRF and muscular strength), physical activity self-efficacy, and physical self-concept (CRF and muscular strength). The interaction between sport involvement and gender was not significant, suggesting these relationships existed equally for the boys and girls.

Emerging Adults Delay Mental Illness Treatment: Another Manifestation of Experiential Avoidance?

Description: Emerging adulthood is a term coined to recognize 18 to 25 year-olds who engage in self-exploration while not yet fully identifying as adults. Many emerging adult college students experience stress, anxiety, and depression. Although many colleges provide affordable and available mental health resources for students, many students who need help appear to not utilize these services. Gaining greater understanding of underlying processes that influence psychological treatment-seeking behavior is imperative. The current study sought to explore the role experiential avoidance (EA) plays as a treatment-seeking barrier in the context of emerging adulthood. Undergraduate students completed online measures of emerging adulthood dimensions, psychological symptoms, EA, self-stigma of, perceived public stigma of, intentions to, and attitudes and beliefs towards seeking treatment, treatment seeking behavior, and a demographics questionnaire. Binomial hierarchical logistic regressions and correlational analyses examined the relationship of EA and treatment-seeking behaviors, accounting for known barriers and emerging adult characteristics. After controlling for demographic variables, results indicated that EA was significantly positively correlated with self-stigma (r = .187), p < .001), perceived public stigma (r = .178, p < .001), intentions (r - .207, p < .001), psychological symptoms (r = .713, p < .001), and attitudes and beliefs (r = .009, p = .003). These and other findings are discussed further, along with the study limitations and implications, as well as possible future directions for work in this area.

High School Teachers' Perceptions of Giftedness, Gifted Education, and Talent Development

Description: In the field of gifted education, there is little research on the perceptions of high school teachers of the gifted about giftedness, good gifted education practices, and the nature and needs of gifted learners. The purpose of this study was to form a deeper understanding of how those educators who guide gifted learners out of high school and into adulthood perceive giftedness and gifted education. This qualitative study, conducted in two phases, took place in a large suburban school district with three large high school systems and was focused on the responses of high school teachers to assess their attitudes, feelings, and opinions about the nature and needs of gifted learners using a grounded theory model of analysis. Data collected from the 11 participants in the first phase of the analysis was combined with that collected from the 13 participants in phase two and validated throughout with continual comparison through memoing. Participants reported a general lack of engagement with scholarly work in the gifted education field as well as a dependence on the school district for effective training in classroom practice. Evidence also suggested a view of giftedness among the participants as an inherent quality of some people who needed to be properly trained in the instructional environment. Implications from this study suggest further research, both qualitative and quantitative, needs to focus on clarifying the perception of giftedness among high school teachers as well as how the delivery of effective training to those teachers can be implemented.

Assessing Rainfall Interception by Urban Tree Canopies in Denton, Texas

Description: Rainfall interception is one mechanism by which tree canopies can reduce surface runoff in urban areas. The objectives of this research were to: 1) quantify rainfall interception by urban tree canopies, and 2) determine the influence of vegetation and microenvironmental factors on rainfall interception rates. In the city of Denton, Texas, 30 mature post oak (Quercus stellata) and blackjack oak (Quercus marilandica) trees were selected for study. Trees were assigned to one of three categories: clusters of trees on greenspace (CG), isolated trees on greenspace (IG), and isolated trees surrounded by pavement (IP). Throughfall (the volume of water that travels through the canopy and reaches the soil surface) collectors were placed beneath these trees and rainfall collectors were placed in nearby open areas. Throughfall and rainfall were collected daily from 19 March to 4 July. Interception was calculated as the difference between throughfall and gross rainfall. Over the study period, there were 27 days with measurable rainfall; daily rainfall ranged from 1-51 mm. Over the sampling period, rainfall interception for individual trees ranged from -10% to 49%, indicating high spatial variability in interception. Percent interception was highest for the CG treatment (22.7 ± 3.8 SE), intermediate for IG (27.4 ± 2.3 SE), and lowest for IP (9.1 ± 4.9 SE). Factors like wind exposure, wind-driven rain and overall tree health may help explain this variability. This research will contribute to our knowledge of hydrological fluxes in urban areas and the role of urban green infrastructure in stormwater runoff mitigation.

The West Point Band's Wind Commissioning Project in Celebration of the Bicentennial of the United States Military Academy

Description: The United States Military Academy Band, also known as the West Point Band is the oldest active band in the United States Army and the oldest unit at the United States Military Academy, and is considered to be one of the finest military musical organizations in the world. The band has also been instrumental in facilitating the creation of new works for wind band.As the commissioning of new music has been essential to the expansion of the wind band's repertoire, several major commissioning projects were undertaken in the mid-twentieth century by various organizations, including the West Point Band, the Goldman Band in conjunction with the League of Composers and later the American Bandmasters Association, Kappa Kappa Psi and Tau Beta Sigma, the American Wind Symphony, and the College Band Directors National Association. These commissioning projects and many others have contributed hosts of new quality works to the repertoire of the wind band. The West Point Band's 1952 commissioning project celebrating the Sesquicentennial of the United States Military Academy was among the first of these mid-twentieth century commissioning projects to seek out prominent composers of the day and have them write works for wind band. The project contributed several seminal pieces to the wind band's repertoire, including Morton Gould's Symphony for Band: West Point. In 1996, as tribute to both the Academy and to the earlier commissioning project, the West Point Band sought to celebrate the Academy's 2002 bicentennial in a similar fashion by commissioning well-known composers to contribute substantial wind works. These pieces would be premiered and recorded by the West Point Band over a number of years, including a gala Bicentennial Celebration concert at Carnegie Hall in March 2002. The purpose of this study is to create a consolidated written record of the wind music composed for the West ...
