Dual gate MOSFET structures such as FinFETs are widely regarded as the most promising option for continued scaling of silicon based transistors after 2010. This work examines key process modules that enable reduction of both device area and fin width beyond requirements for the 16nm node. Because aggressively scaled FinFET structures suffer significantly degraded device performance due to large source/drain series resistance (RS/D), several methods to mitigate RS/D such as maximizing contact area, silicide engineering, and epitaxially raised S/D have been evaluated.

Scriabin's piano miniatures are ideal for the study of evolution of his style, which underwent an extreme transformation. They present heavily concentrated idioms and structural procedures within concise form, therefore making it more accessible to grasp the quintessence of the composer's thought. A plethora of studies often reviews isolated genres or periods of Scriabin's legacy, making it impossible to reveal important general tendencies and inner relationships between his pieces. While expanding the boundaries of tonality, Scriabin completed the expansion and universalization of the piano miniature genre. Starting from his middle years the 'poem' characteristics can be found in nearly every piece. The key to this process lies in Scriabin's compilation of certain symbolical musical gestures. Separation between technical means and poetic intention of Scriabin's works as well as rejection of his metaphysical thought evolution result in serious interpretive implications. Music of Scriabin provides an excellent opportunity for a performer to find a proper balance between rational and intuitive. The lack of any of these qualities will impoverish his works, making their interpretation incomplete. Following one of main Scriabin's ideas - synthesis of all arts - this study approaches his music not from the narrow analytical, but broad synthetic standpoint. The …

Arnold Cooke composed many works for oboe including two sonatas, a concerto and several pieces for chamber ensembles; however, his works are rarely performed. Through the analysis of form and tonality in his first oboe sonata, Cooke's musical style and influences become apparent. His musical style was primarily influenced by his teacher, Paul Hindemith, and can be characterized by traditional forms with the contemporary use of quartal harmonies and a variety of tertian sonorities. Cooke wrote music that is accessible for performers and audience members, and one way he achieved this accessibility is through the repetition of melodic ideas. In addition to exact melodic repetition, he also unified his works through fugue-like passages and sequences. Although he lived during a time of experimentation by many composers, Cooke maintained conservative elements in his music that he learned through his studies at Cambridge and through his studies with Hindemith. His first oboe sonata is tonal although he varied modes and used chromatic harmonies throughout. Cooke's clear writing and unique sound in his Sonata for Oboe and Piano (1957) provide oboists a solo piece for the repertoire that demonstrates a modern approach to the traditional style of composition.

The purpose of this study was to investigate the relationship between a principal's emotional intelligence and personality and his or her ability to implement and develop professional learning communities within the school. The Professional Learning Community Assessment (PLCA) was administered to principals and teachers in 13 schools in Texas ranging from elementary to high school. Based on the strength of the PLCA scores, two elementary schools were selected to participate in case study research. The principals of these two campuses were administered an emotional intelligence instrument (MSCEIT), a personality instrument (DiSC), and were interviewed along with three of their teachers. The findings indicate that both of these principals scored high in the Influential and Conscientiousness subscales and low in the Dominance subscale. The principals also possessed either near-average or above-average emotional intelligence with both principals scoring particularly strong in the Strategic subscale.

The purpose of this dissertation is to analyze Concerto No.3 "Ave Maria" by Alemdar Karamanov (1934-2007) and to elucidate the work through historical background and the composer's ideas. This concerto is presented as a significant gesture of dramatic emotion, religious belief, romantic spirit and universal feeling. The subtitle "Ave Maria" relates to a set up already present within the music program. An analysis of interval relationships will help performers better realize Karamanov's music language. In view of the complicated nature of this piece, an analytical study is considered necessary. The study centers principally on analysis, with an emphasis on the developments of form, tonality and motives to help performers better understand the work, and how to best approach this concerto.

This dissertation presents a historical and analytical study of the organ works of Anthoni van Noordt. Van Noordt's Tabulatuurboeck is one of the most important music publications in mid-seventeenth-century Netherlands. It gives unique, valuable information on organ playing of its time. The process of discrete analysis has led to the identification and exploration of many details, such as extensive use of pedal, the reliance of the composer on rhetorical principals of composition, and his integration of the Italian and German principals of ensemble techniques. The dissertation is divided into three major parts. The first part contains chapters on van Noordt's biography based on available archival documents as well as a chapter on the organ and its role in seventeenth -century Amsterdam. The second part is solely dedicated to the Tabulatuurboeck examining the physical and technical features of the publication including the style of the publication, the letter and staff notation, hand positions, and rhetorical components. Finally, the third part studies the music and its peculiar characteristics with separate chapters on the variations and fantasias.

John Stevens was commissioned by the Chicago Symphony Orchestra (CSO) and the Edward F. Schmidt Family Commissioning Fund to compose a concerto for its principal tubist, Gene Pokorny. The piece began with multiple conversations between composer and performer and from these meetings actualized the influences that shaped the work. The most important influences that the performer mentioned were his passions for American steam locomotives and the Three Stooges, both of which were used by Stevens in his rendering of the composition. This concerto was designed to be played on the famous CC York tuba that was played by the former principal tubist of the CSO, Arnold Jacobs, the same instrument used today. Insight into the history of the York tuba will be given as well as their influence on contemporary manufacturing and design. Focus is given to how Stevens writes the piece idiomatically to the CC tuba and potential performance problems when a performer uses tubas of a different key. Conversations with both gentlemen will display the non-musical influences on Journey and how this effects the composition. Stevens' compositional language is explored and discussed in respect to the challenges and idiosyncrasies within the work. Collegiate tuba professors provide explanation for …

The purpose of this research is to examine through sociological and psychological theories how women make sense of the desire and attainment of breast implants for graduation. The study used a qualitative approach and focused on women ages 18-35 in the state of Texas who have received breast implants for graduation. The sample size in this study included 10 high-school graduates receiving implants as a gift and their 10 mothers. Seven theoretical paradigms provided a better understanding for why the daughters asked for breast implants and why the parent(s) paid for them. Symbolic interaction theory explained why the daughters wished to replace their "fake" cotton padded self with their augmented self, to become the most authentic woman possible. Social construction of reality theory explained why both mothers and daughters wanted to conform to the social construction of gender, and to accomplish their gender well. Conspicuous consumption theory demonstrated how cosmetic surgery practices allow women to appear wealthy, gain status, and "flash" their assets. Feminist theory explained why some women were motivated to capture the attention of men and others altered the body out of empowerment. Reference group and social comparison theories explained how the women in this study were influenced …

This study documents the career of Joseph Eger (b. 1920), who had a short but remarkable playing career in the 1940s, 1950s and early 1960s. Eger toured the United States and Britain as a soloist with his own group, even trading tours with the legendary British hornist, Dennis Brain. He recorded a brilliant solo album, transcribed or arranged several solos for horn, and premiered compositions now standard in the horn repertoire. He served as Principal Horn of the New York Philharmonic, Los Angeles Philharmonic, and the National Symphony. Despite his illustrious career as a hornist, many horn players today do not recognize his name. While Eger was a renowned horn soloist in the middle of the twentieth century, he all but disappeared as a hornist, refocused his career, and reemerged as a conductor, social activist, and author. This dissertation seeks to be the long-overdue comprehensive documentation of Eger's career as the first American horn soloist and his contributions to the world of horn playing. First, a biography of Eger is presented, focusing especially on his education and career as an orchestral player, soloist, and recording artist, including its intersections with the lives of many prominent musicians and personalities of the …

In order to better understand runoff characteristics from natural gas well sites in north central Texas, the City of Denton, with assistance through an EPA funded 104b3 Water Quality Cooperative Agreement, monitored storm water runoff from local natural gas well sites. Storm water runoff was found to contain high concentrations of total suspended solids (TSS). Observed TSS concentrations resulted in sediment loading rates that are similar to those observed from typical construction activities. Petroleum hydrocarbons, in contrast, were rarely detected in runoff samples. Heavy metals were detected in concentrations similar to those observed in typical urban runoff. However, the concentrations observed at the gas well sites were higher than those measured at nearby reference sites. Storm water runoff data collected from these sites were used to evaluate the effectiveness of the water erosion prediction project (WEPP) model for predicting runoff and sediment from these sites. Runoff and sediment predictions were adequate; however, rainfall simulation experiments were used to further characterize the portion of the site where drilling and extraction operations are performed, referred to as the "pad site." These experiments were used to develop specific pad site erosion parameters for the WEPP model. Finally, version 2 of the revised universal …

This qualitative action research study examines how critical theory defined and guided my practice as an art teacher educator while I provided inclusion training for seven preservice art teachers during their student teaching. Sources of data included a personal journal, the inclusion curriculum I created for the preservice teachers and questionnaires and interviews. Primary findings indicated that critical theory had a substantive impact on the evolving development of my teaching philosophy, in particular my attention to issues of power redistribution in the classroom and my developing notion of teaching as form of artistry. The findings of this study also indicate that the primary impact of critical theory upon the preservice teachers was the articulation of their personal narratives and its relation to the development of their teaching identities. Further, mentoring these preservice art teachers in critical theory increased their competence in solving educational dilemmas. A primary finding of this study was how significant of a role the supervising or mentor teacher plays in developing preservice teachers' identity. As this is acknowledged, valued and utilized, more collaborative relationships among these stakeholders in the education of the preservice art teacher can be forged. The study provides implications for art teacher educators as …

Etudes and method books played had an important role in teaching technique and musicality for all musicians. Euphonium players have been using pedagogical materials originally written for other brass instruments such as trumpet, cornet, and trombone. Those materials have been very effective in helping euphoniumists learn skills to play idiomatic nineteenth and early twentieth century repertoire. In recent years, many solo pieces for euphonium demanding advanced techniques have been composed. The difficulty of these solo works for euphonium has increased dramatically in the second half of the twentieth century. Traditional etudes and method books do not cover all the necessary techniques to play this modern repertoire. In the last two decades, many collections of etudes have been written specifically for euphonium, and several of them are technically challenging and aimed at advanced euphoniumists. This trend can be seen in the United States, France and England. In this paper, traditional standard pedagogical materials currently used by euphoniumists will be evaluated. Recent publications of pedagogical materials written exclusively for euphonium after 1990 will be introduced, and effective uses of old and new pedagogical materials for current euphonium players will be presented. An annotated list of the latest etudes composed exclusively for euphonium …

The conduct of young adults has long been a concern in societies. The primary objective of this study was to gain greater understanding of what influences the deviant behavior of young adults in Turkey. Factors assessed in their background included family rituals, self-esteem, religiosity and deviant behavior. It was expected that levels of family rituals, religiosity, self-esteem and other risk factors would be significantly different between incarcerated youth and youth not incarcerated. Overall, these higher levels of family rituals, religiosity, and self-esteem plus lower levels of other risk factors were expected to negatively affect young people's engagement in deviant behavior in Turkey. Walter Reckless' containment theory provided a framework for this study. The non-probability sample of Turkish youths consisted of 205 incarcerated respondents and 200 college students. Each responded to four survey instruments, the Family Rituals Questionnaire, the Culture Free Self-Esteem Inventory, the Religious Background and Behavior Questionnaire, and a Family Information Inventory. Data were gathered cross-sectionally from January through March of 2007. The incarcerated respondents significantly practices less family rituals and had lower levels of religiosity than the college students but they did not differ significantly on self-esteem. Furthermore, overall participation in family rituals was associated with decreased likelihood …

This study investigated what constitutes a teaching curriculum for students with autism in inclusive classrooms in Thailand. The researcher employed 3 qualitative methods: semi-structured interviews, document analysis of curricula and lesson plans, and nonparticipant observations. Six schools were selected as the sites. Participants for interview included 6 principals and 24 teachers. The researcher observed one inclusive classroom for each of the 6 selected schools. The study concentrated on 3 questions: (a) What contributes to appropriate instructional curricula to promote teaching of students with autism in inclusive classrooms in Thailand? (b) What teaching strategies improve the achievement and learning skills of students with autism in inclusive classrooms in Thailand? (c) What are the problems of curricula for teaching students with autism in inclusive classroom in Thailand? Key findings for the research questions were as follows: Common features of effective curricula for teaching students with autism in inclusive classrooms include opportunities, health care, specialized curriculum, students' individual needs and abilities, guidelines of teaching, teacher training and supervision, transition plan, parent involvement, tools/classroom environment, and students' class assignments. The teaching strategies include varying the teaching format (large group, small group, and one-on-one), teaching functional communication (giving direction, close-ended questions or open-ended questions), reinforce …

The research described in this dissertation examines the possible link between self-regulated learning and LEGO Mindstorms robotics activities in teaching concepts in an introductory university computer programming course. The areas of student motivation, learning strategies, and mastery of course objectives are investigated. In all three cases analysis failed to reveal any statistically significant differences between the traditional control group and the experimental LEGO Mindstorms group as measured by the Motivated Strategies for Learning Questionnaire and course exams. Possible reasons for the lack of positive results include technical problems and limitations of the LEGO Mindstorms systems, limited number and availability of robots outside of class, limited amount of time during the semester for the robotics activities, and a possible difference in effectiveness based on gender. Responses to student follow-up questions, however, suggest that at least some of the students really enjoyed the LEGO activities. As with any teaching tool or activity, there are numerous ways in which LEGO Mindstorms can be incorporated into learning. This study explores whether or not LEGO Mindstorms are an effective tool for teaching introductory computer programming at the university level and how these systems can best be utilized.

The main purpose of this study was to consider the effects of amplification and vocal function exercises on the perceived vocal health of elementary music educators (N = 37) from Oklahoma (n = 11) and Texas (n = 26). Participants were assigned to the use of the ChatterVoxTM amplifier or vocal function exercises based on pretest scores on the Voice Handicap Index with Music Teacher Voice Questionnaire (VHI/MVQ). Following the 4-week study period, participants completed the posttest VHI/MVQ. The results of a one-way ANCOVA that used treatment group as the independent variable, the summed posttest scores as the dependent variable, and the summed pretest scores as the covariate or control variable indicated that there was a statistically significant difference between the adjusted means for the posttest scores, favoring the exercises group. The overall group and both treatment groups reported frequent loud voice use in work settings and in public places. The overall group and the amplification group reported hoarseness after prolonged talking. The exercises group did not report as great a problem with hoarseness after prolonged talking. Secondary purposes addressed demographic variables. Women perceived greater overall vocal difficulties than men; men frequently reported specific vocal complaints that were not commonly …

This study investigated the effects of interactive lessons and learning style on student learning outcomes in self-defense education classes. The study utilized an experimental design that incorporated four self-defense education classes at the University of North Texas (UNT) during the fall semester 2007 (N = 87). A pre-test was administered during the first week of class to determine prior knowledge of the participants. The Visual Auditory Reading/Kinesthetic Inventory (VARK) was used to assess the learning styles of the students and was completed after the pre-test of knowledge was administered. The treatment group received the interactive lesson and the control received a paper review. The difference between the pre and posttest was used as a measure of improvement of the student's learning outcomes. A 2 (treatment/control) by 2 (pretest/posttest) ANOVA with repeated measures was conducted to examine the differential improvement in knowledge across the intervention. Based on the 2-way ANOVA there was a significant difference between the treatment group and the control group based on their learning outcomes. A repeated measures ANOVA was conducted to determine if there was a significant difference between the groups based on the pre and post test scores. Based on the results of a one week …

The dynamical origin of complexity is an object of intense debate and, up to moment of writing this manuscript, no unified approach exists as to how it should be properly addressed. This research work adopts the perspective of complexity as characterized by the emergence of non-Poisson renewal processes. In particular I introduce two new complex system models, namely the two-state stochastic clocks and the integrate-and-fire stochastic neurons, and investigate its coupled dynamics in different network topologies. Based on the foundations of renewal theory, I show how complexity, as manifested by the occurrence of non-exponential distribution of events, emerges from the interaction of the units of the system. Conclusion is made on the work's applicability to explaining the dynamics of blinking nanocrystals, neuron interaction in the human brain, and synchronization processes in complex networks.

This study investigated relationships of age, gender, and supervisor level with job satisfaction, organizational commitment, stress perception, and turnover intention. The demographics were hypothesized to moderate the stress-satisfaction and commitment-turnover relationships. Hypotheses were tested using both parametric and non-parametric bootstrap methods. Subjects were taken from a national survey of 2,663 public sector IT workers. Missing data were imputed using NORM software. Ordinary least squares (OLS) regression indicated a significant direct effect from all main variables and covariates, except for age on turnover intent. No mediating effects were found. Age-Commitment was the only significant higher order modifier relationship, although Gender-Commitment explained substantial variance. LMG statistic results enabled the predictors to be rank ordered with confidence intervals. Best subset bootstrap regression explored all possible predictor orders to confirm which model explained the most variance. The original model and predictor sequence were confirmed. The bootstrap AIC statistic provided a model which maximized explained variance while optimizing parsimony. Since only age had a mediating effect, Hypotheses 1 and 2 were not supported. All other hypotheses were partially confirmed.

As several Italian baroque violoncello transcriptions have entered the standard performance repertory for both high school and collegiate tubists, and as numerous texts, articles, and baroque performance instruction courses have illuminated a new realm of performance possibilities, no published document has provided specific, thorough, and sample approaches to performance on the tuba of a given piece (or pieces) through a detailed application of materials found in any singular source or combination of sources. Many of the existing articles and texts that approach the subject focus largely on ornamentation, while limiting the discussion and application of the following topics: tempo, spirit, affect, notation, rhythm, dynamics, and articulation. This document examines such topics and provides detailed explanations and suggestions of historically-informed characteristics applicable to two movements each from the R. Winston Morris transcription of Antonio Vivaldi's Sonata No. 3 in A Minor and the Donald C. Little/Richard B. Nelson transcription of Benedetto Marcello's Sonata No. V in C Major.

The present study sought to build on the large body of past research into written disclosure of traumatic memories. This research has consistently found that participants who write about their traumatic experiences realize long-term physiological and psychological health benefits. More recently, it has been found that those participants who realize the most benefits are those who progressively include more elements of a good narrative, or story, in their writing about a traumatic experience over several sessions. Therefore, research has begun to examine the role of language and the structure of language in the health benefits gained from written disclosure of traumatic memories. A guided written disclosure protocol was designed for the present study, which sought to aid participants in supplying an increasing amount of narrative structure to their written disclosures of a single traumatic experience. Participants (N = 30) completed several measures of psychological and physiological health prior to and one month after completing the guided written disclosure protocol. Analyses revealed that participants who completed all four writing sessions showed statistically significant reductions in symptoms of general psychological distress, obsessive-compulsive symptoms, and intrusive and avoidant symptoms related to the traumatic experience. No significant self-reported physiological health benefits were found. The …

The purpose of this study was to explore the various animal assisted interventions mental health professionals incorporate in the therapeutic treatment process, as well as the various therapeutic purposes intended with each technique. Participants were recruited from animal assisted therapy related databases. Participants included professionals who practiced in the mental health field. Thirty one participants qualified for the study. A survey was developed based on information found reviewing literature related to animal assisted therapy. Nineteen animal assisted therapy techniques and ten therapeutic intentions were identified from a review of the literature. Participants were asked to rate on a Likert scale how often they incorporated each technique in their treatment process. Additionally, participants were asked to identify which therapeutic purposes they intended with each technique. Results indicated participants incorporated a variety of animal assisted techniques for various therapeutic intentions. Results indicated seven animal assisted techniques were incorporated by more than 50% of the participants. Building rapport in the therapeutic relationship was the most common therapeutic intention reported with a variety of animal assisted techniques.

Trusted platform modules (TPMs) are hardware modules that are bound to a computer's motherboard, that are being included in many desktops and laptops. Augmenting computers with these hardware modules adds powerful functionality in distributed settings, allowing us to reason about the security of these systems in new ways. In this dissertation, I study the functionality of TPMs from a theoretical as well as an experimental perspective. On the theoretical front, I leverage various features of TPMs to construct applications like random oracles that are impossible to implement in a standard model of computation. Apart from random oracles, I construct a new cryptographic primitive which is basically a non-interactive form of the standard cryptographic primitive of oblivious transfer. I apply this new primitive to secure mobile agent computations, where interaction between various entities is typically required to ensure security. I prove these constructions are secure using standard cryptographic techniques and assumptions. To test the practicability of these constructions and their applications, I performed an experimental study, both on an actual TPM and a software TPM simulator which has been enhanced to make it reflect timings from a real TPM. This allowed me to benchmark the performance of the applications and test …

This document examines the technical execution of extended techniques incorporated in the musical structure of Solus, and explores the benefits of introducing the work into the curriculum of a college level trumpet studio. Compositional style, form, technical accessibility, and pedagogical benefits are investigated in each of the four movements. An interview with the composer forms the foundation for the history of the composition as well as the genesis of some of the extended techniques and programmatic ideas.
