Poor sleep measured across many dimensions has been linked to adverse physical and mental health outcomes including cardiovascular disease, diabetes, cancer, increased mortality, depression, and anxiety. Current research typically relies upon brief, subjective, inadequately validated methods to assess limited dimensions of sleep, resulting in inaccurate measurements and possibly faulty conclusions. Specifically, research validating objective (e.g., actigraphy) and subjective (e.g., sleep diaries, retrospective surveys) measurement methods against the gold standard of polysomnography (PSG, an overnight sleep study) is primarily limited by a) a lack of reliability based on too short (e.g., 24 or 48 hours) of an assessment period to capture night-to-night variability, b) a lack of ecological validity (e.g., full PSG in a laboratory setting), and c) a lack of generalizability due to limited or special populations (e.g., individuals with insomnia). Barriers such as prohibitive cost, extensive setup time, and personnel training requirements diminish the ability of researchers to conduct measurement comparison studies using gold standard measures like traditional PSG. These barriers can be circumvented with the use of low-cost, minimally invasive single-channel EEG devices (e.g., Zmachine), but to date few studies have employed these devices. The current study evaluated the accuracy of retrospective surveys, sleep diaries, and actigraphy compared …

Contemporary music for horn often requires techniques and musical or notational considerations that are unconventional with respect to the standard pedagogy of the instrument. As such, these considerations often represent a level of challenge to which the average-intermediate to advanced-hornist is unprepared to approach or altogether unfamiliar. The most prominent of these demands arising in the last few decades of the twentieth century through today include microtonality (such as extended just intonation and quarter tones), extended techniques in combination or juxtaposition (such as multiphonics and right hand technique), rhythmic complexity (including metric modulation, non-dyadic meters, additive rhythms, and nested tuplets), and unconventional notations (graphic, spatial, and other temporal notations). This document first surveys the challenges of the repertoire in question, which includes works by György Ligeti, Thea Musgrave, Milton Babbitt, Brian Ferneyhough, Iannis Xenakis, Heinz Holliger, and Douglas Hill, among others. After considering the merits and limitations of existing pedagogical materials that work towards these ends, the document then underlines a strategic pedagogical goal for understanding and approaching unconventional contemporary repertoire through newly-composed etudes. This document is written in conjunction with and justification for the author's 24 Unconventional Etudes for Horn, and includes examples therefrom.

The present study examined the effects of adult attachment and cultural orientation on sacrifice behaviors and the corresponding emotional reactions, using a cross-cultural sample in the U.S. and China. Strain-tests protocol was utilized in this study, in which an individual (i.e., the asker) was asked to share with their romantic partner a personal goal that required a major sacrifice from their partner (i.e., the responder), and then entered a discussion to process their plan of carrying out this goal. The final sample included 115 couples from the U.S. and 99 couples from China. Results indicated that responder's attachment avoidance was negatively associated with sacrifice offered to their partners and they reported more positive emotions as a result. The interaction between attachment anxiety and nationality was significant. Specifically, in the U.S. sample, individuals with high attachment anxiety were more likely to offer sacrifice for their partners, but this effect was reversed in the Chinese sample. In addition, interdependent self-construal (ISC) was a significant moderator for the relation between attachment anxiety and sacrifice behavior. Individuals who endorsed higher ISC and higher anxious attachment were less likely to make sacrifice for their partner. Furthermore, when individual offered more sacrifice, they reported more positive …

This exploratory study investigates how American and Canadian parents living in Saudi Arabia perceive enrolling their children in an online virtual school. This research is relevant to North Americans living and working overseas and how these parents access educational opportunities for their children. North American parents living in Saudi Arabia with children have limited local educational options. If parents decided not to enroll their child in traditional private local international education, alternatives include boarding school, homeschool, or online school. Of the surveyed participants, 68% of parents had enrolled their children in online education or expressed interest in enrolling their children in online education but many lack information and knowledge about online education. A qualitative study analyzed participants in semi-structured interviews. Besides academic satisfaction, the most common reasons for alternative education are the lack of available competitive sports and the arts, including theatre and music. Four themes emerged from the data. Parent satisfaction about their children's education shifts from positive to negative around 8th or 9th grade. Parents are, in general, unwilling to take a risk on an unproven online school. Local private international schools are the focal point of extra-curricular activities and social events, but families lack connections and a …

A large portion of the standard repertoire for saxophone and piano has already been recorded and performed many times and has received significant scholarly study. For a performer, remaining relevant requires learning and performing new compositions. Jorge Sosa and Andrés Alén are both accomplished composers, yet outside of the Latin-American community they remain virtually unknown to most saxophonists. This project serves as an introduction to both composers. Combined, Sosa and Alén have nine compositions for saxophone. Their works include saxophone quartets, saxophone and piano, and saxophone quartet with choir. This study focuses on three compositions: La Zacapaneca by Sosa, Tema con Variaciones and Sonata para Clarinete ó Saxofón Soprano y Piano, both by Alén. Compositional background information is given about each composition to include date of composition, premiers, important recordings, length of performance and Cuban ethnic and traditional elements used as the basis for rhythmic and thematic ideas. The Cuban and Afro-Cuban influences are explained in further detail pertaining to how they were used in the construction of the works and in their being performed stylistically correctly. Dynamics, articulations, and performance considerations are studied at length.

In this dissertation we investigate the applicability of different adaptive techniques to improve the effectiveness and efficiency of the regression testing. Initially, we introduce the concept of regression testing. We then perform a literature review of current practices and state-of-the-art regression testing techniques. Finally, we advance the regression testing techniques by performing four empirical studies in which we use different types of information (e.g. user session, source code, code commit, etc.) to investigate the effectiveness of each software metric on fault detection capability for different software environments. In our first empirical study, we show the effectiveness of applying user session information for test case prioritization. In our next study, we apply learning from the previous study, and implement a collaborative filtering recommender system for test case prioritization, which uses user sessions and change history information as input parameter, and return the risk score associated with each component. Results of this study show that our recommender system improves the effectiveness of test prioritization; the performance of our approach was particularly noteworthy when we were under time constraints. We then investigate the merits of multi-objective testing over single objective techniques with a graph-based testing framework. Results of this study indicate that the …

The study of Borel equivalence relations on Polish spaces has become a major area of focus within descriptive set theory. Primarily, work in this area has been carried out using the standard methods of descriptive set theory. In this work, however, we develop a model-theoretic framework suitable for the study of Borel equivalence relations, introducing a class of objects we call Borel structurings. We then use these structurings to examine conditions under which marker sets for Borel equivalence relations can be concluded to exist or not exist, as well as investigating to what extent the Compactness Theorem from first-order logic continues to hold for Borel structurings.

Today's globalized world presents challenges for formulating language education policies in multilingual countries, and postcolonial Nigeria presents a dramatic illustration because of ongoing colonial influences as well as neocolonial factors. This study focused on dialectical relations over time among languages in Nigeria's National Policy on Education (NPE), published in 1977, 1981, 1998, 2004, 2013, and 2014. The title of the study harks to Chinua Achebe's novel, Things Fall Apart, which described the disruption of tribal cultures and languages when Europeans brought their culture and language to Nigeria. Attention in this dissertation, which examined Nigerian education policy over four decades, was also on things falling apart, being resolved in some way, and then falling apart again. Four major dialectical tensions can be seen as the NPE went through revisions in language of instruction and language of study. First, relations between English and indigenous languages showed the increasing importance of English despite ostensible attempts to promote indigeneity through language. Particularly important was the influence of globalization, which emphasized neoliberal values and initiatives associated with global English. Second, relations among the various indigenous languages showed three languages—Hausa, Igbo, and Yoruba—to be privileged over 522 other languages that were marginalized but retained as "mother …

The Social Cognition and Object Relations Scale—Global (SCORS-G) is a relatively new scoring system for the Thematic Apperception Test (TAT) that provides information about an individual's functioning in a variety of domains, including intrapsychic and interpersonal. Participants in this archival study had been administered a variety of measures as part of a routine clinical assessment, including the TAT, Rorschach, Minnesota Multiphasic Personality Inventory-2, and the Wechsler Adult Intelligence Scale. Selected TAT stories were rescored using current SCORS-G scoring criteria. This dissertation evaluated the factor structure of the SCORS-G in an outpatient sample with a principal component analysis (PCA), finding support for a two-component solution. The SCORS-G was then compared to well-established measures of personality functioning, social cognition, and object relations using correlational analyses, with mixed results. Lastly, support was found for using the SCORS-G as a tool for discriminating individuals with a history of violent or problematic relationships from those without such a history. Implications for card selection based on card pull and the impact of bland protocols were explored.

The purpose of this phenomenographical case study is to explore the ways in which a group of MFA students conceive of their learning as they are enmeshed within an MFA community. The research follows along two guiding research questions: 1) What does artistic learning involve for graduate students in an MFA community? 2) How is one's artistic practice shaped by one's active participation in an MFA community? The findings of this study have been presented as lines of artistic learning and help to show the various conceptions that MFA students have of their learning as artists while in an MFA program of study. Ultimately, it is in better understanding one's lines of artistic learning that MFA students can be better supported in their journeying to become professional, practicing artists.

Audiovisual concatenative synthesis is an analysis-driven granular technique using a corpus of multimedia data to sequence audio and video streams on a microtemporal level. This text outlines my development of this technique as a tool for multimedia composition, using my work, Replica, as a case study. The paper illustrates how the concepts of granular structure, gesture capture, and replication are integral not only to the software but to the architecture of the composition. In doing so, machine learning approaches to music and visual art are reviewed and related to my personal compositional practice. Additionally, I attempt to show how audiovisual concatenative synthesis provides a composer with strategies for shaping one's sense of time through disorienting audiovisual cues and tightly organized counterpoint between sound and image, stage and screen, and the real and virtual.

Business and higher education are two different worlds with different missions, values and priorities. Privatized student housing partnerships have brought these two worlds together with little information on how they work and the challenges they face. Research indicated that through collaboration, skilled leadership and an understanding of students, healthy relationships could exist. The purpose of this study was to provide awareness of these existing partnerships and the current perceptions from leaders from both higher education and business working within present collaborations. It sought to uncover and bring awareness to the challenges experienced in order to create a dialogue around them. Feedback obtained from 30 professionals working within public-private partnerships from both the business and higher education worlds provided insight into existing perceptions and challenges. Semi-structured interviews where utilized and customized using eight open-ended questions that were different for each group. A purposeful sampling approach was used to select the participants based on their existing partnership with a privatized student housing company. Out of the thirty participants, twenty were chief officers within higher education and ten business officers. Analysis of the thirty interviews depicted three major themes: the two worlds: business and higher education, the bridge: leader of the village and …

Adverse childhood experiences (ACEs) are a certain set of abuse household dysfunction experiences that many children in the United States experience. Children who experience multiple ACEs are more likely to have negative mental and physical health issues as they grow older. These outcomes include ADHD, depression, cancer, heart disease, and early death. In this study, I examined the effectiveness of child centered play therapy (CCPT), a developmentally appropriate treatment modality, with children who have experienced two or more ACEs and who are also demonstrating inattention and impulsivity symptoms. Participants were 34 students from five Title 1 elementary schools in the southwest United States (28 males and 6 females; age range 5-8 years old with a mean age of 6.12). In the sample, participants were comprised of 29.4% African American (n = 10), 38.2% Caucasian (n = 13), 17.6% Hispanic/Latino (n = 6), and 14.7% identified as biracial (n = 5). Participants were randomly assigned to a treatment group that received 16 CCPT 30-minute sessions twice a week (n = 17) or a waitlist control group (n = 17) that received treatment at the conclusion of the study. Using a factorial ANOVA, results indicated statistically significant improvement of CCPT treatment group …

This non-experimental field study examined the relationship between participant reported experiences of relational depth (RD) with their individual counselors in substance use disorder (SUD) treatment and participant reported motivation to change substance use. Participants in the study were clients enrolled in inpatient and outpatient levels of substance use disorder treatment. A total of 78 clients (aged 18-77, with mean age 35.97, 80.1% Caucasian, 11.5% African-American, 3.8% Hispanic, 1.3% Asian, 1.3% multiracial, 1.3% other) with SUDs participated in the study. Results demonstrated that treatment process variables explained approximately 42% of the variance in participant recognition scores. Specifically, substance abuse community support involvement (β = .598, rs2 = .908, p < .001) and relational depth (β = .184, rs2 = .178, p = .045) were found to be significant predictors of participant recognition of a substance use problem. From these results, one may tentatively conclude that community support and the development of relational depth in SUD treatment are valuable additions to standard SUD treatment. Extended results are described and summarized using text, tables, and figures. The study has practical and clinical implications for counselors working with clients in substance use disorder treatment particularly concerning the length of individual counseling.

In this dissertation a computationally efficient cognitive multiple-input multiple-output (MIMO) orthogonal frequency division duplexing (OFDM) detector is designed to decode perfect space-time coded signals which are able maximize the diversity and multiplexing properties of a rich fading MIMO channel. The adaptive nature of the cognitive detector allows a MIMO OFDM communication system to better meet to needs of future wireless communication networks which require both high reliability and low run-time complexity depending on the propagation environment. The cognitive detector in conjunction with perfect space-time coding is able to achieve up to a 2 dB bit-error rate (BER) improvement at low signal-to-noise ratio (SNR) while also achieving comparable runtime complexity in high SNR scenarios.

In Chinese contemporary piano music, large-scale piano compositions featuring innovative polyphonic musical languages are rarely found. Chang-Lei Zhu's Ballade for Solo Piano represents his development of contrapuntal techniques passed on from J. S. Bach and Dmitri Shostakovich in their polyphonic works for solo keyboard or piano. This study focuses on an analysis of Zhu's Ballade as an idiosyncratic composition that makes a significant contribution to the Chinese contemporary piano music repertory. Comparative analysis is made of Zhu's Ballade and J.S. Bach's Well-Tempered Clavier Books 1 and 2, as well as Dmitri Shostakovich's 24 Preludes and Fugues for Solo Piano, Op. 87. Zhu, a living Chinese composer born in 1976, uniquely writes the twenty variations of his Ballade based on the opening theme, a single melody in ten subphrases. This research lays out the close relationship of the opening theme with twenty variations in the Ballade. This study also illustrates how Zhu is an innovative voice in Chinese contemporary piano music literature. This comparative study constitutes the first scholarly study of Zhu's Ballade. Chapter 1 is an introduction to my comparative study. In chapter 2, comparisons on selected excerpts are conducted between Zhu's Ballade and J.S. Bach's WTC, Books 1 and …

In this dissertation I consider the nature of the relationship between orientation and language-habits in the context of environmental ethics. Specifically, I focus on the problem of orientation as a way of understanding the unabated trend of anthropocentrism in the dominant Western language-culture. Orientation operates as the attitudes, beliefs, and feelings in relation to something that we embody in our lived experiences. One way that we communicate our orientation in relation to the land is through our language-habits. In considering our language-habits, I conceptualize a process I call conceptual autopoiēsis. Conceptual autopoiēsis is the co-evolutionary coupling process of the language-habits and language-cultures of human orientation, which recreates the initial conditions of the reproduction of the specific concepts embodied in that given orientation, language-habit, and language-culture. I show how our orientation to the land is embodied in our language-habits and language-cultures. I show how orientation, language-habit, language-culture, and conceptual autopoiēsis all function as the environment from which we select the very conceptualization of our orientation and the language we use to do so. More specifically, metaphysical anthropocentrism is a kind of orientation that assumes a dualistic relationship to the land that perpetuates a disconnect from Nature that makes it impossible to …

Entr'actes and Sappho Fragments (1964) by English Composer Harrison Birtwistle represent extended notation, complex meters, and extended instrumental techniques. After World War II, the style and techniques of musical composition evolved considerably and musical trends began to continuously change. Conducting contemporary compositions requires new approaches in conducting methods. This paper examines a) introduce important elements of Birtwistle's compositions in the 1960, b) include an updated score of Entr'actes and Sappho Fragments (notated by the author), and c) provide a performance guide to the work.

Mario Lavista (b. 1943) is a dominant figure in Mexican classical music. In the second half of the twentieth century, he promoted the use of contemporary techniques, leading to a series of collaborations with expert instrumentalists to explore extended techniques. Marsias for Oboe and Crystal Glasses is one of those pieces. Due to the nature of contemporary techniques, different oboes and reed styles produce different effects with the same fingerings. This document analyzes the contemporary fingerings in the two published editions of the work in consideration of the long-scrape reed style and oboes commonly used in the United States. The contemporary techniques were played on twelve professional oboe models as a way to collect data on how the printed fingerings work. The data is the foundation for the performance guide, which details every contemporary technique in the work. The performance guide also provides comprehensive information about the crystal glass logistics. The document also presents an electronic accompaniment created with Max/MSP in the event that the crystal glasses or crystal glass players are unavailable.

This mixed methods study examined professional development for higher education faculty members at four-year, state supported universities in Texas and the perceptions of professional development leaders at these institutions. The quantitative data was generated through an electronic survey aligned to the second iteration of the technology acceptance model while the qualitative data was generated through semi structured interviews with those that participated with the survey. Univariate analysis was performed on the survey data and the qualitative data was categorized using pattern coding. Limitations and future recommendations were also discussed.

Thermoelectric (TE) devices can undergo degradation from reactions in corrosive environments and at higher operating temperatures by sublimation and oxidation. To prevent the degradation, we have applied two high temperature polymers (HTPs) as coatings for TE materials. Sintering temperatures were from 250°C to 400°C. We explain why dip coating is better technique in our study and had two potential HTPs for tests. By applying TGA (thermogravimetric analysis), we were able to figure out which HTPs have better thermal resistivity. Besides, TGA also help us to find proper curing cycles for HTPs. EDS and SEM results show that the coatings prevent oxidation and sublimation of TE materials. We also shorten HTP curing cycle time and lower the energy costs.

Extant literature has provided evidence suggesting that ethnic minority individuals experiencing discrimination report poor mental health outcomes, including depression, anxiety, and an overall lower sense of belongingness with the majority culture, but empirical research examining how ethnic identity affects this relationship is extremely scarce. The first goal of the current study was to replicate the results of previous studies demonstrating a strong relationship between discrimination and selected wellbeing indicators: meaning in life, American affirmation, depression, and life satisfaction. The second goal of the study was to examine a moderation model and two moderated moderation models that depict the relationships among adult attachment, the affective component of ethnic identity, exploration and commitment to ethnic identity, and wellbeing indicators. Data was collected from 206 students who were recruited from undergraduate psychology courses. Findings provided partial support to the direct effects of discrimination on various wellbeing indicators but did not support the moderating effect of ethnic identity. Additionally, adult attachment, ethnic identity, and discrimination were not found to significantly interact, but the relationship between discrimination, ethnic identity, and American affirmation was found to be significantly moderated by the affective component of ethnic identity. Discussion on the findings, limitations of the study, future research …

Although the population of children attending schools that came from single parent or remarried households is significant, school leaders have failed to institute policies regarding the involvement of nonresident parents. School districts should have procedures to educate personnel on the legal rights of nonresident parents. To avoid confusion concerning legal terms, the term "nonresident" had been utilized to describe a biological parent with whom the child did not reside. This differs from the term "noncustodial." The purpose of this study was to investigate whether school districts in the North Texas area had specific written policies or administrative requirements that addressed the involvement of nonresident parents in the educational decision-making process for their child at IEP meetings. The conceptual framework for this study was founded on the premise that aside from instruction, three factors contributed to the achievement of students who received special education and related services: parental involvement, special education law, and school policy. School districts were polled via paper surveys distributed in person to special education leaders during director meetings and where they were reported to exist, a review of documents was performed. A summary of findings is presented with implications for practice and recommendations for school leaders, including …

Video modeling interventions have been mostly effective for individuals with autism spectrum disorder (ASD) in teaching social communication skills. However, differences in the effectiveness of these interventions have been noted. Participant motivation was suggested as one of the factors that can influence the effectiveness of video modeling. The purpose of this study was to investigate the effects of participant motivation on video modeling for teaching social communication skills to individuals with ASD. A combined multiple probe across participants and adapted alternating treatments design was used to examine the differential effects of two video modeling conditions (i.e., motivated and non-motivated) on social communication skills of four adults with ASD. Of the four participants, three participants responded to the intervention and performed more of target behavior during the motivated video modeling condition than the non-motivated video modeling condition, while one did not respond to the intervention. In addition, the three participants engaged in a higher percentage of the target behavior during motivated generalization sessions than non-motivated generalization sessions. The results demonstrated that participant motivation influenced the effectiveness of video modeling.
