This study presents a set of data analysis approaches for single subject designs (SSDs). The primary purpose is to establish a series of statistical models to supplement visual analysis in single subject research using Bayesian estimation. Linear modeling approach has been used to study level and trend changes. I propose an alternate approach that treats the phase change-point between the baseline and intervention conditions as an unknown parameter. Similar to some existing approaches, the models take into account changes in slopes and intercepts in the presence of serial dependency. The Bayesian procedure used to estimate the parameters and analyze the data is described. Researchers use a variety of statistical analysis methods to analyze different single subject research designs. This dissertation presents a series of statistical models to model data from various conditions: the baseline phase, A-B design, A-B-A-B design, multiple baseline design, alternating treatments design, and changing criterion design. The change-point evaluation method can provide additional confirmation of causal effect of the treatment on target behavior. Software codes are provided as supplemental materials in the appendices. The applicability for the analyses is demonstrated using five examples from the SSD literature.

In this self-study inquiry, I studied my graphic design practice in a professional setting, focusing on my Arabic typographic skills and knowledge. My roles as researcher and design educator indivisibly intertwined throughout this research. I worked to understand the value of calligraphy in art and design education, highlighting its power as an art form while also emphasizing its pedagogical potentials. I utilized two theoretical approaches suited to investigating and understanding the Arabic letters as text and image, Ibn Arabi’s science of letters, or 'ilm al-hurûf, and semiotics. I applied my theoretical framework to three distinctive artworks to investigate their uses of the Arabic letters, contemplating their roles in modern and contemporary Arab art. Essential to my research was learning Arabic calligraphy through two approaches: 1) I attended a calligraphy workshop, and 2) I conducted three self-study experimentations. I analyzed my experience through visual representations, commentary, and narrative inquiry to assess Arabic calligraphy’s significance for graphic design education. As such, my experimentations confirmed Arabic calligraphy’s aesthetic and educational value. I employed my findings to create a contemporary Arabic typography curriculum suitable for university-level students. This curriculum is built on learning theories such as visual culture analysis, semiotics, constructivist theory, play principles, …

Premature termination is a substantial problem with significant adverse effects for clients, therapists, and treatment organizations. Unfortunately, it is also a relatively common phenomenon within mental healthcare settings. Across varied mental healthcare settings, rates of premature termination have reportedly ranged from 19.7 % to 40 %. Perhaps not surprisingly, the rate of premature termination in training clinics is substantially higher than in community mental health settings and private practice, with 75 to 80 % of clients ending treatment services prematurely. The purpose of this study was to explore the combined effect of intake therapist continuity or discontinuity, and quality of the therapeutic relationship on premature termination. Intake therapist continuity, measures of working alliance, and termination outcome from 524 clients at the University of North Texas Psychology Clinic were utilized for adults receiving individual therapy services between August 2008 and August 2013. Results of the study suggest intake therapist continuity did not predict subjective termination status (X2(2, n = 524) = 1.61, p = 0.45), nor did it predict change in symptomology status (X2(3, n = 453) = 1.14, p = 0.77). Additionally, working alliance predicted subjective termination status (X2(6, n = 212) = 21.17, p < 0.01), but not change …

The study is undertaken for a more compressive understanding for organizational theory and its applicability to tendency towards improvisation during emergency times among individuals in Non Profit Organizations (NPOs) in Saudi Arabia. The analysis involved an examination of direct effect of learning on tendency towards improvisation and possible mediating effects between organizational learning and tendency towards improvisation among individuals in NPOs, while controlling for key demographic differences (e.g. individuals’ age, education level and years in service, number of full-time staff and volunteers). Self-administered questionnaires were distributed to full-time employees in 13 NPOs in three cities in the western area of Saudi Arabia, namely Jeddah, Makkah and Madinah (N= 304). The main statistical method employed to hypotheses examination was Structural Equation Modeling. The hypothesis examination resulted in three out of five hypnotized paths are to be significant. Two direct relations were interpreted as outcomes of organizational learning, with increases in the level of organizational learning is being positively related to individuals’ self –efficacy and agility. The third significant path interpreted as individuals’ agility is positively related to their tendency to improvise during emergency times, which indicates organizational learning has indirect effect on tendency towards improvisation. Finally, the applicability of organizational learning …

This research project aims to clarify the factors that impact successful aging in Assisted Living facilities (ALFs) in Denton County, Texas. We hypothesize that social disengagement decreases physical and mental components of quality of life. This exploratory research project employed standardized questionnaires to assess residents in the following domains; HRQOL, social engagement status, level of cognition, depression, and the level of functioning. This study collected data from 75 participants living in five ALFs. The average of Physical Component Scale (PCS) and Mental Component Scale (MCS) was 35.33, and 53.62 respectively. None of the participants had five or more social contacts out of facilities, and two-third of them had two or less social contacts. On average, those participants who were more socially engaged had higher score of MCS compared with disengaged counterparts. The level of physical function significantly affects social engagement, when people with more disabilities are more likely to be socially disengaged. Social engagement and depression significantly impact MCS, when depression is a mediating factor between social engagement and mental component of quality of life. Considering the expansion in aging population in the United States within the next three decades, the demand for high quality long-term care will skyrocket consequently. …

The changing landscape of demographics, technology, and diversity in the learning environment is challenging schools around the world to rethink their approaches to the implementation of high-quality teaching practices. Classroom practices are becoming more complex because educators have to ensure that their students are well-equipped with 21st century skills (e.g., Darling-Hammond, 2010; Dede, 2010; Griffin, McGaw, & Care, 2012). Educators, curriculum developers, and school administrators need to be more than experts in pedagogy. They are now required to keep up with current ideas, innovative instructional practices, and the results of a variety of educational reform efforts. Believing that teachers’ beliefs are the most important psychological construct with regard to instructional practices (Pajares, 1992) and that teachers’ beliefs are related to their choice of classroom practices and, ultimately, the students’ performance (Bybee, Taylor, Gardner, Van Scotter, Powell, Westbrook, & Landes, 2006; Staub & Stern, 2002), the author of this study utilizes the international data set of the Teaching and Learning International Study (TALIS) 2013 to examine the associations between teachers’ constructivist beliefs, their self-efficacy beliefs, professional activities, and the school principals’ instructional leadership as related to lower secondary school teachers and principals in South Korea, Finland, and Mexico. These three countries …

The wind octet was a popular ensemble of the classical period. In 1782, the Viennese Emperor formed a wind octet which specialized in playing opera arrangements. This music was used primarily as a form of background entertainment for dinners. This guide analyzes and compares the works of several well-known arrangers from the classical period in order to demonstrate arranging styles of the time. The arrangers of the period were often the performers of these various wind octets who were writing specifically for the players in their own ensembles. The style of Mozart’s original wind music is also discussed, in contrast to the arrangements of his works made by others. This guide is intended for serve performers of today as a tool to learn the art of arranging in an historical style. Idiosyncrasies of the classical-period wind instruments are discussed, as they relate to the style of wind arranging. The role of the contemporary arranger is compared with that of the classical period, and the case is made for the need for more contemporary arrangements of classical works using period arrangers as models.

The Sonata in B minor occupies a hallowed position in Liszt’s oeuvre, according to scholarly assessment. Despite the plethora of literature on this consummate work, the vast majority of writings on the sonata have focused almost exclusively on formal innovation, thematic transformation, and programmatic speculation, and there is a dearth of interpretative analysis of the sonata based on its fascinating autograph manuscript, even though it has been publicly accessible and widely available in facsimile for some four decades now. In view of the fact that the autograph manuscript has never been examined for the express purpose of improving performance of the sonata, this dissertation proposes to approach this problem with the direct examination of the autograph and its numerous additions and deletions, and the analysis of the many interpretive implications stemming from the surprising insights offered by the autograph itself, which is on deposit at the Pierpont Morgan Library in New York City. The goal of the dissertation is to make readily accessible a comprehensive performance-oriented study of this summit of pianism, offering solutions to the many discrepancies among its various published editions, from the first Breitkopf & Härtel in 1854 to the most recent Peters Urtext in 2011, and …

In this phenomenological study I investigated the experiences of early second-career, tenure-track faculty members who entered academe after working in a position outside of higher education for at least five years. The purpose of this study was to learn about experiences and factors that contributed or impeded to the success of second-career faculty members. Eight early second-career faculty members, from a four-year university located in the Dallas Metroplex area, were interviewed. Participants demographics were ages 34 to 68 with the average age being 45; 50% male and 50% female; and one African American, six Caucasian, and one Hispanic and/or Latino. Participants’ previous professional experience was a benefit in teaching and relating to students, in understanding the complex university bureaucracy, and in setting goals. The participants reported that mentoring, whether formally assigned by the institution or through informal means such as departmental colleagues or professional organizations, was a benefit to all of the participants. A primary area of concern for the participants was collaboration and collegiality with other faculty members. Participants stated that traditional faculty members lack the skills and training to collaborate effectively in researching and in joint teaching endeavors. Participants reported that they had to monitor and restrain their …

In this dissertation we study closure properties of pointclasses, scales on sets of reals and the models L[T2n], which are very natural canonical inner models of ZFC. We first characterize projective-like hierarchies by their associated ordinals. This solves a conjecture of Steel and a conjecture of Kechris, Solovay, and Steel. The solution to the first conjecture allows us in particular to reprove a strong partition property result on the ordinal of a Steel pointclass and derive a new boundedness principle which could be useful in the study of the cardinal structure of L(R). We then develop new methods which produce lightface scales on certain sets of reals. The methods are inspired by Jackson’s proof of the Kechris-Martin theorem. We then generalize the Kechris-Martin Theorem to all the Π12n+1 pointclasses using Jackson’s theory of descriptions. This in turns allows us to characterize the sets of reals of a certain initial segment of the models L[T2n]. We then use this characterization and the generalization of Kechris-Martin theorem to show that the L[T2n] are unique. This generalizes previous work of Hjorth. We then characterize the L[T2n] in term of inner models theory, showing that they actually are constructible models over direct limit of …

With the increase in emergent bilinguals and higher standards for all, the challenge for educational stakeholders is to fully utilize dual language programs as a prominent means toward meeting and surpassing rigorous state and national standards. Part of maximizing dual language programs’ impact, and the purpose of this study, was to provide detailed analyses of program models and student biliteracy development. Thus, the research questions sought to explore the level of understanding and implementation of dual language programs in general and the biliteracy component in particular at each campus, before documenting the second through fifth grade English and Spanish reading biliteracy trajectories of students at each school. Both campuses experienced more challenges in the implementation of the program structure, staff quality, and professional development rather than in curriculum and instruction. Furthermore, although both campuses’ students experienced positive trajectories towards biliteracy by the end of fifth grade, each campus was characterized by different rates and correlation between English and Spanish reading growth in each grade. Finally, the researcher conducted a split plot MANOVA to examine how much variance in the biliteracy trajectories was explained by school attendance, gender, initial English oral language and initial Spanish oral language; only school of attendance …

Children and Adolescents with emotional and behavioral disabilities (EBD) are often involved in aggression, acting out, bullying, violence, substance abuse, and juvenile crime. However, the limited Korean studies have focused primarily on bullying of students with developmental disabilities or intellectual disabilities. Therefore, the current study aimed to explore contributing factors to traditional bullying and cyberbullying in Korean children and adolescents with EBD. The current study surveyed 112 students with EBD between ages of 10 and 15 and their parents (guardians). The results revealed that internalizing problem behaviors including anxious/depression, withdrawal/depression, and somatic problems significantly affected traditional bullying victimization of Korean students with EBD. The peer support was a significant factor affecting cyberbullying victimization. Furthermore, the maternal psychological control was a meaningful factor affecting perpetration at school and in cyber world. Based on the findings, the present study described implications regarding prevention and intervention programs for addressing traditional bullying and cyberbullying victimization and perpetration.

COPD is the third leading cause of death in the United States and is the sixth leading cause of death for low-to middle income countries (Downs & Appel, 2006; GOLD, 2011). COPD is a largely preventable disease due to the lifestyle factors that heavily contribute to disease onset and severity. Although traditionally COPD research has focused on health outcomes related to risk factors, compliance, comorbid psychological and physical conditions, and treatment interventions, a growing body of research suggests religious and spiritual factors may play an equally important role in health outcomes for several medical conditions, including pulmonary disease. However, studies of this kind have not specifically examined COPD nor have they examined the role of religious and spiritual beliefs in COPD management among ethnic minority patients. As such, the current study aimed to examine whether spiritual ethnic minority patients with COPD hold religious fatalistic attitudes and less active religious problem solving . A sample of 35 ethnic minority patients from the Louis. B. Stokes Cleveland VA Medical Center (LSCVAMC) Outpatient Pulmonary Clinic in Cleveland, OH. were recruited to participate in the study. Due to the acknowledgeable limitations of the present study, results are preliminary but convey associations between religious health …

Suppose that G is a finite, unitary reflection group acting on a complex vector space V and X is a subspace of V. Define N to be the setwise stabilizer of X in G, Z to be the pointwise stabilizer, and C=N/Z. Then restriction defines a homomorphism from the algebra of G-invariant polynomial functions on V to the algebra of C-invariant functions on X. In my thesis, I extend earlier work by Douglass and Röhrle for Coxeter groups to the case where G is a complex reflection group of type G(r,p,n) in the notation of Shephard and Todd and X is in the lattice of the reflection arrangement of G. The main result characterizes when the restriction mapping is surjective in terms of the exponents of G and C and their reflection arrangements.

As a doctoral student, I was asked to teach a course based on emerging technologies and postmodern methods of inquiry in the field of art education. The course was titled Issues and Applications of Technology in Art Education and I developed a method of inquiry called animated autoethnography for pre-service art educators while teaching this course. Through this dissertation, I describe, analyze, interrogate, value, contextualize, reflect on, and artistically react to the autoethnographic animated processes of five pre-service art educators who were enrolled in the course. I interviewed the five participants before and after the creation of their animated autoethnographies and incorporated actor-network theory within the theoretical analysis to study how the insights of my students’ autoethnographies related to my own animations and life narratives. The study also examines animated autoethnography as a method of inquiry that may develop or enhance future teaching practices and encourage empathic connections through researching the self. These selected students created animations that accessed significant life moments, personal struggles, and triumphs, and they exhibited unique representations of self. Pre-service art educators can use self-research to create narrative-based short animations and also use socio-emotional learning to encourage the development of empathy within the classroom. I show …

Student clarinet performers often encounter bass clarinet for the first time in a high school or university wind ensemble, so it is logical for clarinet pedagogues to encourage and assist their students in learning this wind band literature. In addition to becoming familiar with this oft performed repertoire, students will develop a set of specialized bass clarinet skills that one cannot learn on soprano clarinet. These skills include increased air capacity and support, timbre consistency in differing registers, intonation tendencies of the lower instrument, voicing flexibility, right hand thumb dexterity for keys that do not exist on soprano clarinet, technical facility for eleven pinky keys (as opposed to the seven pinky keys on a typical soprano clarinet, and effective altissimo fingerings. The purpose, then, of this document is to provide a performance guide for select bass clarinet solo excerpts from the wind band literature and to provide supplemental exercises intended to help students acquire the specialized bass clarinet skill set they will need in order to perform the selected excerpts successfully. The solos discussed in this document are excerpted from H. Owen Reed’s La Fiesta Mexicana, Florent Schmitt’s Dionysiaques, Percy Grainger’s Lincolnshire Posy, Frank Ticheli’s Blue Shades, William Bolcom’s First …

Understanding the process of consumers during key purchasing decision points is the margin between success and failure for any business. The cultural differences between the factors that affect consumers in their decision-making process is the motivation of this research. The purpose of this research is to extend the current body of knowledge about decision-making factors by developing and testing a new theoretical model to measure how culture may affect the attitudes and behaviors of consumers in restaurants. This study has its theoretical foundation in the theory of service quality, theory of planned behavior, and rational choice theory. To understand how culture affects the decision-making process and perceived satisfaction, it is necessary to analyze the relationships among the decision factors and attitudes. The findings of this study contribute by building theory and having practical implications for restaurant owners and managers. This study employs a mixed methodology of qualitative and quantitative research. More specifically, the methodologies employed include the development of a framework and testing of that framework via collection of data using semi-structured interviews and a survey instrument. Considering this framework, we test culture as a moderating relationship by using respondents’ birth country, parents’ birth country and ethnic identity. The results …

Given issues in education concerning teacher shortages, the omnipresence of alternative certification programs and the growth of online programs in higher education, this study investigated teacher retention for 77 secondary education teachers who completed an online teacher preparation program in Texas. Teacher retention was examined from 2003-2013 and investigated the influence of factors such personal characteristics, working conditions and school setting characteristics on teacher retention. Data was collected electronically utilizing a survey instrument designed by two teacher education experts and I. A total of 21 variables and two open-ended questions were investigated using the survey instrument. Exploratory factor and hierarchical multiple regression analyses were conducted to identify a multi-factor model for teacher retention utilizing the participants' survey responses. These analyses yielded evidence of the program's effectiveness in preparing teachers for long careers. Specifically, the areas of program support, field experience, and classroom management were statistically significant factors that contributed positively to teacher retention. Additionally, variables outside the program, were examined. These factors included personal characteristics, working conditions, and school setting factors. The predictor model accounted for 56% of the variance; F (17, 54) = 3.015; p = < 0.001. In particular, working conditions contributed to 41% of the variance associated …

Prior research on incumbent firm response to radical technological innovation identifies firm, technology, and environmental factors associated with incumbents’ performance after a technology shift. What remains unexplored are factors affecting choice of response made before a technological shift occurs. Such ex ante choices are important intermediate outcomes affecting long-term performance outcomes. Competitive considerations may be influential inputs in choice processes because technological innovation is often related to competitive strategy. The resulting research question for this study is: What role do competitive considerations play in incumbent firms’ ex ante strategic choices in response to potentially radical technological innovations? Findings from a survey of key informants in the electronics industry whose firms face a potential technological disruption (n=120) suggest that incumbents’ response choices are affected by competitor-related orientations and by perceptions of relative strength of their strategic assets. Limited support is found for a moderating effect of perceptions of the competitive environment. The results of this study extend theory on incumbent response to radical technological change by shedding light on the influence of competitor interdependence. Findings also suggest the importance of strategic choice as an intermediate variable in understanding incumbents’ long-term performance. Research examining choice factors at varied stages of a technology’s …

Today’s military encompasses a wide variety of families who are affected by deployments in multiple and complex ways. Following deployments, families must reconnect in their relationships and reestablish their way of life. Appropriate and effective communication during this time is critical, yet many military couples struggle with this process. Moreover, student service members/veterans and their families are in a unique position. In addition to coping with changes in their marital relationship, student veterans may feel isolated or unsupported on college campuses, often experiencing anxiety, depression, posttraumatic stress, or suicidality. The current study seeks to bridge the gap between the military family literature and the student service member/veteran literature by examining how deployment experiences, mental health issues, and communication patterns influence post-deployment relationship adjustment among student veterans. Analyses tested whether communication style and/or current mental health concerns mediate associations between combat experiences and couples’ relationship adjustment, as well as between experiences in the aftermath of battle and relationship adjustment. Results suggest that although posttraumatic stress is significantly related to deployment experiences among student veterans, participants report no significant negative effects of deployment on relationship adjustment. Communication style, however, was significantly associated with relationship adjustment, and a lack of positive communication was …

Athletes may be at increased risk for developing disordered eating and pathogenic weight control behaviors due to pressure for their bodies to look a certain way and perform at a high level (Sundgot-Borgen & Torstveit, 2004). Petrie and Greenleaf (2013) proposed a psychosocial model to explain the development of athletes’ disordered eating behaviors. Specifically, they suggested that unique weight/body pressures of the sport environment, general societal pressures about attractiveness, internalization of societal appearance ideals, body dissatisfaction, drive for muscularity, negative affect, and dietary restraint combine and contribute to the development of bulimic symptomatology. The aim of the current study is to test the Petrie and Greenleaf model in a large, nation-wide, diverse sample of male collegiate athletes. Participants were male collegiate athletes (N = 731; Mage = 19.91, SD = 1.50) representing 17 sports and National Collegiate Athletic Association (NCAA) Divisions I, II, and III. Participants completed a demographic questionnaire and measures designed to assess their experiences of the above constructs. Structural equation modeling was used to test the pathways proposed in the Petrie and Greenleaf (2013) etiological model. Results suggest that sport pressures, such as those from coaches and teammates about weight, the importance of appearance, and looking good …

Teachers appear to feel challenged by children’s off-task behavior in the classroom. Children’s off-task behavior can result in reduced academic engagement, increased teaching stress, and strained teacher-child relationships. The purpose of this study was to investigate the impact of kinder training on young children’s on-task behavior in the classroom. This study utilized an experimental single-case methodology and a multiple baseline across subjects design. Three elementary school teachers conducted weekly individual play sessions with students they identified as frequently exhibiting off-task behavior. The three children ranged in age from five to six years: two males and one female, two Caucasian non-Hispanic and one biracial. Two trained observers repeatedly assessed the child participants’ on-task behavior using the Direct Observation Form throughout the baseline and intervention phases. The findings provide support for kinder training as an effective play-based professional development-training model that can improve children’s on-task behavior. Results demonstrated that all child participants showed improvement in on-task classroom behavior. Visual analysis revealed that all child participants demonstrated a positive change in on-task behavior during the intervention phase. All teacher participants reported observing improvement in the child participants’ on-task behavior and teacher-child relationships. Teachers’ post-intervention reports supported the notion of reciprocal interactions among teacher-child …

Early childhood is a critical period during which children develop social-emotional competence that will affect future success. Developing social-emotional assets is of importance for kindergarten children because of their concurrent cognitive and social changes as well as the experience of transitioning from home to school environment. A growing number of schools have adopted social-emotional learning (SEL) programming to focus on fostering children’s prosocial behaviors through direct instruction and engaging activities in classroom settings. However, some researchers have proposed that learning should capitalize on children’s natural interests rather than adult-determined agendas. Based on theoretical assumptions regarding potential effectiveness of child-centered group play therapy (CCGPT) as a treatment modality, I sought to explore the effects of CCGPT on social-emotional assets of kindergarten children utilizing parent and teacher reports across pretest, posttest, and one-month follow-up. Additionally, given that group sizes have been inconsistent and rarely explored across previous studies, I investigated the therapeutic aspect of group sizes in CCGPT outcome by comparing 2-member and 3-member CCGPT groups. Forty-three participants with mean age of 5.14 were recruited from three elementary schools, including 19 Hispanic, 14 Caucasian, and 10 African American. Twenty-one participants were randomly assigned to the intervention group receiving a mean of 15.32 …

In 1861, Jerôme Savari (1819-1870) composed Duo for Soprano Saxophone and Alto Saxophone. Since then, more than 400 duets were written, yet many musicians are not aware of this repertoire. The lack of recommended repertoire and insufficient information regarding this genre reduces the use of the saxophone duet in both pedagogical and concert settings. The purpose of this study is to examine the importance of the saxophone duet genre by identifying the standard repertoire and creating an annotated bibliography. Twenty-three composers with twenty-six selected works have been identified and will be annotated. All selected works in this document are (1) composed for any two members of the saxophone family; (2) originally composed for saxophone duet (i.e., no transcriptions will be included); (3) published either by companies or by the composers themselves; and, (4) composed between the nineteenth-century through present day. This annotated bibliography of selected repertoire contains two sections: (1) repertoire for performance; and, (2) repertoire for pedagogy. It is the intent of this project that the annotation for each piece could assist performers, teachers and students with their search of currently published works for this genre. The descriptive information in each annotation regarding the composition and its performance considerations …
