Exploring the Dual-natured Impact of Digital Technology on Student-classroom Engagement in a Texas Public High School
The past decade has become rife with an eagerness to integrate new digital technology into teaching. While there have been decades of research done on the importance of curriculum and pedagogy on student engagement, findings of actual technology integration are scarce. Moreover, what does it take to engage students in classroom activities and lessons when technology is introduced? The purpose of this study was to explore how digital technology, when integrated into classroom teaching and activities, impacted the students-classroom engagement based on the interim-cognitive, meta-cognitive, motivational, and behavioral markers. This was explored in a Texas public high school across the four core classes (English, Math, Science, and Social Studies. Data was collected in the form of observational field notes, transcripts of recorded lessons, and Likert-scaled surveys. Thematic analysis was used in analyzing qualitative data, Pearson’s correlation of those components found by factor analysis verified three of the five themes identified from the thematic analysis with statistical significance. The findings suggest that mere use of technology does not have a profound impact on student engagement. Instead, technology tends to amplify the existing classroom culture and social norms agreed upon between the teacher and their students. Texas teachers and students are also redefining the meaning of curriculum to include technology as a result of the attempted integration. This research finds that students’ hands-on activities under teachers’ guidance with the use of technology excel when teachers are molding digital work. digital.library.unt.edu/ark:/67531/metadc822755/
Exploring the Effectiveness of Curriculum Provided Through Transmedia Books for Increasing Students’ Knowledge and Interest in Science
Transmedia books are new and emerging technologies which are beginning to be used in current classrooms. Transmedia books are a traditional printed book that uses multiple media though the use of Quick Response (QR) codes and augmented reality (AR) triggers to access web-based technology. Using the transmedia book Skills That Engage Me students in kindergarten through second grade engage in curriculum designed to introduce science skills and careers. Using the modified Draw-a-Scientist Test (mDAST), observations and interviews, researchers analyzed pre and post data to describe changes students have about science and scientists. Future study may include the development and validation of a new instrument, Draw a Science Student, and examining the mDAST checklist with the intention of updating the parameters of what is considered positive and negative in relationship with work a scientist conducts. digital.library.unt.edu/ark:/67531/metadc822809/
Exploring the Evolutionary History of North American Prairie Grouse (Genus: Tympanuchus) Using Multi-locus Coalescent Analyses
Conservation biologists are increasingly using phylogenetics as a tool to understand evolutionary relationships and taxonomic classification. The taxonomy of North American prairie grouse (sharp-tailed grouse, T. phasianellus; lesser prairie-chicken, T. pallidicinctus; greater prairie-chicken, T. cupido; including multiple subspecies) has been designated based on physical characteristics, geography, and behavior. However, previous studies have been inconclusive in determining the evolutionary history of prairie grouse based on genetic data. Therefore, additional research investigating the evolutionary history of prairie grouse is warranted. In this study, ten loci (including mitochondrial, autosomal, and Z-linked markers) were sequenced across multiple populations of prairie grouse, and both traditional and coalescent-based phylogenetic analyses were used to address the evolutionary history of this genus. Results from this study indicate that North American prairie grouse diverged in the last 200,000 years, with species-level taxa forming well-supported monophyletic clades in species tree analyses. With these results, managers of the critically endangered Attwater's prairie-chicken (T. c. attwateri) can better evaluate whether outcrossing Attwater's with greater prairie-chickens would be a viable management tool for Attwater's conservation. digital.library.unt.edu/ark:/67531/metadc271815/

Exploring the Gender Role Ideology of Black and White Men Between Ages 18 to 30
This research is a qualitative study that explores the gender role ideology of Black and White men between the ages of 18-30. The study found that both groups are moving toward egalitarianism on different pathways. The pathways illustrate the effect of racial identity on gender role ideology. White respondents had a progressive egalitarianism which stemmed from ideas reflected individualism, secularization, and the identification with the grand narrative of the United States. Their respondents also reflected postmodern ideas. Overall their ideas reflect larger White racial identity and shows an overlap between the progressive understanding of modernity and with postmodernist ideas of non-deterministic definitions. Black respondents had a collaborative egalitarianism which stemmed from historical racial and economic deprivation. Subsequently, Blacks gender role ideology illustrates collaboration and communal interdependence between of Black men and women, and the Black church. Blacks tended to view things from a social perspective that was often reactionary. Overall, their ideas reflected the larger Black racial identity which emphasizes collaboration between men and women and a reliance on community based institutions like the Black church. digital.library.unt.edu/ark:/67531/metadc500185/
Exploring the Impact on Self-regulated Learning: a Comparative Analysis of Learner Experiences Using Problem-based Learning, Game Play, and Computer-based Instruction
The ability to transfer what you know to new and different contexts is a sign of successful learning. While students often graduate from college with the required number of courses many lack the skills necessary to apply appropriate strategies to solve problems in different contexts, to reason, and think critically. More than a decade ago the Boyer Report (1995) pointed to this fact as a sign that Universities were falling short in adequately supporting their undergraduate populations. As a result, it is not uncommon to see educational institutions introducing new courses and programs geared towards helping students learn better. This study explores learner experiences and the impact on self-regulated learning within a distributed learning setting when motivated by problem-based learning, game play, and computer-based instruction. In this study the instructional design of the course introduced undergraduate students to authentic learning experiences in which students engaged in collaborative problem solving and learning activities framed within the narrative of an alternate reality game. Fifteen self-regulated learning constructs were examined. The comparison group engaged with problem solving tasks and computer-based instruction. Additionally, the study used the theory Learning and Teaching as Communicative Action and its four communicative actions as a lens to understand the full range of student interactions and how they constructed knowledge. The research design employed computer-mediated discourse analysis to examine qualitative data. Data was triangulated through constant-comparative coding of student communication in the form of web logs, emails, student assignments, and semi-structured interviews. Review and consensus building was embedded in the process of identifying emerging codes and categories, and used to support emergent inferences before the final themes were identified and mutually agreed upon. Finally, to evaluate the outcome of the instructional design, pre and posttest measures were used among groups using a two-sample t-test. Statistical significance was used to determine changes in learning outcomes while select qualitative codes were examined and reviewed to gauge student satisfaction with the instructional approach. Results indicated substantial qualitative and quantitative differences among the three versions of the course related to self-regulated learning practices and communicative action in particular in terms of student interaction, and knowledge construction. Additional, findings revealed differences in epistemic beliefs about learning, which in turn influenced how students chose to learn. These outcomes are presented and discussed along with the implications for instructional design. digital.library.unt.edu/ark:/67531/metadc500031/
Exploring the Impacts of Fashion Blog Type and Message Type on Female Consumer Response Towards the Brand
The current study examines the influences of blog type and blog message type on consumers’ perceptions of brand credibility and brand similarity. Additionally, the study seeks to understand the interaction effects of blog type and message type on brand credibility and brand similarity and on consumer engagement with a blog. The findings reveal that message type, specifically product message, is an important consideration when marketers want to illustrate similarities between the brand and consumers. Additionally, it was found that product messages should be considered when encouraging consumer engagement with a blog. However, blog type did not have an effect on consumer perceptions of brand credibility and similarity or consumer engagement. digital.library.unt.edu/ark:/67531/metadc407834/
Exploring the Integration of Near-Death Experience Aftereffects: Summary of Findings
Abstract: Preliminary evidence suggests that both near-death experiencers (NDErs) and nonexperiencers who learn about near-death experiences (NDEs) show beneficial aftereffects. In this article I summarize the findings of an exploratory study to examine a small group process utilizing spiritual guidance and expressive arts for integrating NDE aftereffects. Eleven adult participants -- four NDErs and seven non-NDErs -- completed a pretest, initial posttest, and longitudinal posttest consisting of a revised version of the Omega Life Change Questionnaire (Rominger-LCQ) and the Human Spirituality Scale, as well as semistructured individual and group interviews. I also collected the expressive art participants created during sessions, photographed it, and used it to identify pictorial themes. Quantitative results included some significant differences and some nonsignificant trends indicating greater spirituality and life changes among NDErs compared to non-NDErs and, for all participants, from pre- to posttest. Qualitative interview material revealed participants had learned material on a number of topics of including a broader understanding of, and ability to communicate about, the NDE. Qualitative pictorial data revealed themes suggesting that both NDErs and non-NDErs had integrated positive aftereffects. The process described herein may benefit spiritual guides and directors, expressive art therapists, and therapists working with individuals who have had an NDE or other spiritually transformative experience. I also discuss methodological benefits of using artistic inquiry. digital.library.unt.edu/ark:/67531/metadc461753/
Exploring the Integration of Thai Traditional Music in Chakra by Narong Prangchareon, with a Conductor’s Guide
This dissertation explores the integration of Thai traditional music in Chakra, for wind band, by Narong Prangchareon. Nipat Kanchanahud explores how Narong, inspired by Eastern philosophy, integrates elements of Thai traditional music and the types, styles, scales, and dialects of Thai culture with the formal elements of Western music and the instrumentation of the Western wind band. Chakra uniquely spans Eastern and Western cultures, creating a new musical language for both worlds to appreciate and enjoy. Further, the composition richly demonstrates the viability of the wind band as an international medium. The orchestration of Chakra reveals Narong’s musical lineage from Edgard Varèse through Chen Yi. A conductor’s guide, included with this dissertation, is designed to aid and encourage performances of Chakra throughout the world. digital.library.unt.edu/ark:/67531/metadc804989/
Exploring the Private Music Studio: Problems Faced by Teachers in Attempting to Quantify the Success of Teaching Theory in Private Lessons through One Method as Opposed to Another
I present strategies and methods for teaching fundamentals of music theory in the context of the private music studio through a variety of techniques and research. Beginning with a background in educational psychology, examples of behaviorist and cognitive teaching models are presented, and how each applies to teaching music is explained. Two detailed examples of actual lessons are presented, coupled with musical examples, to describe both the process and the concepts that can be presented. A qualitative experiment based upon the learning styles of three music students and the effect of different teaching styles when teaching the same concept is presented and discussed in detail. digital.library.unt.edu/ark:/67531/metadc5356/
Exploring the relationship between continuing professional education and job satisfaction for information technology professionals in higher education.
The study had four main hypotheses that examined the relationships between job satisfaction and the reasons for attending continuing professional education (CPE). The purpose of this study was to examine the relationships between training and job satisfaction with the objective of adding to the body of knowledge related to both job satisfaction and training and development. Participation Reasons Scale was used to measure the reasons for attending CPE activities, and the Job in General Scale and Job Descriptive Index was used to measure job satisfaction. The surveys were administered over the Internet to information technology professionals working in higher education. The participants were contacted by email with a message explaining the purpose of the research and a Web link that took the participants directly to the survey. After collecting the data, it was exported into SPSS and analyzed using Spearman Rho and Mann Whitney U statistics and a simple structure exploratory factor to determine any underlying structures between the job satisfaction and CPE. digital.library.unt.edu/ark:/67531/metadc5296/
Exploring the Relationships Between Faculty Beliefs and Technology Preferences
All too often faculty are asked to implement technology into their teaching without the knowledge necessary to use the technology effectively. Due to the evolution of technology in everyday settings, students have come to expect to be engaged through technological means. This often creates undue stress on faculty members. The purpose of this study is to investigate technology integration by exploring the relationships between a faculty member’s technology preferences and educational beliefs. Through a mixed method, this study attempts to address the question of why faculty use the types of technology they do. More importantly, this study investigates if a faculty member’s educational beliefs have any influence on the technology they choose to use. Thirty-two medical, clinical, and healthcare faculty members participated in the study. They responded to a Teaching Perspectives Inventory (TPI) survey and a Technology Preferences survey with open-ended questions. Data analysis revealed multiple statistically significant findings between different beliefs and different types of technology. The results indicated that personal epistemic beliefs influence the types of technology faculty use. The technology choices faculty make are largely related to tools they are comfortable with and ones they believe effectively fit their teaching materials. The study also found statistically significant differences between age, gender, and reported technology use. It is suggested faculty development programs should consider faculty members’ educational beliefs and personal preferences when supporting faculty with their uses of technologies. digital.library.unt.edu/ark:/67531/metadc799481/
Exploring the Relationships Between Mindfulness, Self-compassion, and Ethnic Identity Development
Ethnic identity development is a process that occurs for all individuals, and weakness in ethnic identity is associated with numerous psychosocial difficulties. Security in ethnic identity can be difficult for those exposed to varying attitudes and behaviors in a multicultural society. As such, the current study examined the influence of mindfulness and self-compassion on ethnic identity development. a sample of 479 undergraduate students completed online self-report questionnaires measuring demographic information, mindfulness, self-compassion, ethnic identity status, and self-esteem. Results suggested that mindfulness and self-compassion are significant negative predictors of ethnic identity, and that self-compassion was a better predictor of ethnic identity status than was mindfulness. Self-compassion did not moderate the relationship between mindfulness and ethnic identity status, as was hypothesized. the sample included primarily Caucasian (n = 278) individuals born in the United States, which likely limited generalizability of findings. Implications of the current findings and suggestions for future research are discussed. digital.library.unt.edu/ark:/67531/metadc115160/
Exploring the role of secondary attachment relationships in the development of attachment security.
The process by which earned-secures achieve attachment security in adulthood, despite having insecure parent-child relationships in childhood, was the focus of the current study. As internal working models are thought to be formed within relationships, specifically primary attachment bonds (Bowlby, 1969), it was postulated that secondary attachment relationships, specifically those that were positive, had the capacity to revise insecure models of self and other. In the current study, the secondary attachment histories of undergraduates who were earned-secure and continuously-insecure, or insecurely attached since childhood, were compared. A new measure of secondary attachment quality was developed (Questionnaire About Secondary Attachment Figures (Q-SAF)), which was used to measure undergraduates' perceptions of their past and current secondary attachment figures. Findings indicated that in comparison to continuous-insecures, earned-secures perceived their negative secondary attachment figures in adolescence as less mean. Earned-secures also reported being less dependent upon these figures' approval of them for their self-worth and more secure within these relationships. In adulthood, earned-secures reported more trust and intimacy with their positive secondary attachment figures. Compared to continuous-insecures, earned-secures described their peers as being more empathic and altruistic during childhood and more warm during adolescence; earned-secures also reported less dependency and greater closeness with their peers throughout development. Grandparents were listed the most frequently by earned-secures as positive secondary attachment figures during childhood and this number was more than double that for continuous-insecures. Further, earned-secures described their grandparents in childhood as being more altruistic and they reported being less concerned with receiving their acceptance. Siblings from childhood were described by earned-secures as being more empathic than those of continuous-insecures, yet earned-secures also reported greater dismissing attachment to their siblings and cousins in childhood. Significant others from adolescence were rated by earned-secures as being less mean than those of continuous-insecures and earned-secures reported being more securely attached to these relationships in both adolescence and adulthood. Implications of the current study and directions for future research are presented. digital.library.unt.edu/ark:/67531/metadc4891/

Exploring Trusted Platform Module Capabilities: A Theoretical and Experimental Study
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 the feasibility of the proposed extensions to standard TPMs. My tests also show that these constructions are practical. digital.library.unt.edu/ark:/67531/metadc6101/

Exposing Deep-rooted Anger: A Metaphor Pattern Analysis of Mixed Anger Metaphors
This project seeks to serve two purposes: first, to investigate various semantic and grammatical aspects of mixed conceptual metaphors in reference to anger; and secondly, to explore the potential of a corpus-based, TARGET DOMAIN-oriented method termed metaphor pattern analysis to the study of mixed metaphor. This research shows that mixed metaphors do not pattern in a manner consistent with statements made within conceptual metaphor theory. These metaphors prove highly dynamic in their combinability and resist resonance between SOURCE DOMAINS used. Also shown is the viability of metaphor pattern analysis as a methodology to approach mixed metaphor research. digital.library.unt.edu/ark:/67531/metadc84170/

Expression analysis of the fatty acid desaturase 2-4 and 2-3 genes from Gossypium hirsutum in transformed yeast cells and transgenic Arabidopsis plants.
Fatty acid desaturase 2 (FAD2) enzymes are phosphatidylcholine desaturases occurring as integral membrane proteins in the endoplasmic reticulum membrane and convert monounsaturated oleic acid into polyunsaturated linoleic acid. The major objective of this research was to study the expression and function of two cotton FAD2 genes (the FAD2-3 and FAD2-4 genes) and their possible role in plant sensitivity to environmental stress, since plants may increase the polyunsaturated phospholipids in membranes under environmental stress events, such as low temperature and osmotic stress. Two FAD2 cDNA clones corresponding to the two FAD2 genes have been isolated from a cotton cDNA library, indicating both genes are truly expressed in cotton. Model yeast cells transformed with two cotton FAD2 genes were used to study the chilling sensitivity, ethanol tolerance, and growth rate of yeast cells. The expression patterns of the two FAD2 genes were analyzed by reverse transcription polymerase chain reactions (RT-PCR) and Western blot analyses in cotton plants under different treatment conditions. The coding regions of both FAD2 genes were inserted downstream from the CaMV 35S promoter in the pMDC gateway binary vector system. Five different FAD2/pMDC constructs were transformed into the Arabidopsis fad2 knockout mutant background, and multiple potential transgenic Arabidopsis plant lines harboring the cotton FAD2 genes were generated. The cotton FAD2 genes were amplified by the polymerase chain reaction (PCR) from the genomic DNAs isolated from the transgenic Arabidopsis T1 plant lines. Complementation of the putative transgenic Arabidopsis plants with the two cotton FAD2 genes was demonstrated by gas chromatography analyses of the fatty acid profiles of leaf tissues. The cellular localization of cotton FAD2-4 polypeptides with N-terminal green fluorescence protein (GFP) was visualized by confocal fluorescence microscopy. The phenotype of transgenic Arabidopsis plants transformed with the cotton FAD2-4 gene was compared to Arabidopsis knockout fad2 mutant plants and wild type Arabidopsis plants regarding their sensitivity to low temperature, and the size and height of the plants. digital.library.unt.edu/ark:/67531/metadc9002/
Expression of G-protein Coupled Receptors in Young and Mature Thrombocytes and Knockdown of Gpr18 in Zebrafish
Access: Use of this item is restricted to the UNT Community.
In this study, a novel method based on biotinylated antibodies and streptavidin coated magnetic beads was used to separate the thrombocyte subpopulations from zebrafish whole blood. DiI-C18, a lipophilic dye, labels only young thrombocytes when used at low concentrations. Commercially available biotinylated anti-Cy3 antibody was used to label the chromophore of DiI-C18 on the young thrombocytes and streptavidin coated magnetic beads were added subsequently, to separate young thrombocytes. The remaining blood cells were probed with custom-made biotinylated anti-GPIIb antibody and streptavidin magnetic beads to separate them from other cells. Further, thrombocytes are equivalents of mammalian platelets. Platelets play a crucial role in thrombus formation. The G-protein coupled receptors (GPCRs) present on the platelet surface are involved during platelet activation and aggregation processes. So, thrombocytes were studied for the presence of GPCRs. The GPCR mRNA transcripts expressed in the young and mature thrombocytes were subjected to densitometry analysis and pixel intensities of the bands were compared using one way ANOVA. This analysis did not show significant differences between the young and mature GPCR mRNA transcripts but identified a novel GPCR, GPR18 that was not reported in platelets earlier. To study the function of this GPCR, it was knocked down using GPR18 specific antisense morpholino and vivo morpholino. The immunofluorescence experiment indicated the presence of GPR18 on thrombocytes. The results of the assays, such as, time to occlusion (TTO) and time to aggregation (TTA) in response to N-arachidonyl glycine (NAG) as an agonist, showed prolongation of time in GPR18 larval and adult morphants respectively, suggesting that GPR18 plays a role in thrombus formation in zebrafish. In conclusion, our results indicate that GPR18 may be present in zebrafish thrombocytes, it may be involved in thrombus formation and that NAG may be an agonist at GPR18 on thrombocytes. digital.library.unt.edu/ark:/67531/metadc271881/
Expressive Arts Therapy with Bereaved Families
Most current grief programs support the children and/or parents of bereaved families rather than the family as a whole. This exploratory study was a quantitative and qualitative investigation of the use of expressive arts therapy with bereaved families during a weekend camp experience and a series of followup sessions. The purpose of the study was to determine the effectiveness of using expressive arts activities in improving the functioning of the bereaved family as a whole as well as individual family members. Participants included eight families who lost a child to a chronic illness between 2 to 36 months months prior to the onset of the study. Children ranged in age from 3 to15, and parents ranged in age from 26 to 66, for a total of 27 participants. The Child Life Department at Children's Medical Center of Dallas, a division of The University of Texas Southwestern Medical Center in Dallas, Texas recruited the families. Participants received flyers and invitational letters and registered through the mail. Families attended a weekend camp where they experienced a wide variety of expressive arts activities in a combination of group formats: multi-family groups, parents' group, developmental age groups for children, total childrens' group, individual family group, mothers' group, and fathers' group. The research design was a pretest/posttest quasi-experimental control group design, but a control group could not be established. Therefore, one-tailed t-tests were used to compare participant functioning between the beginning and end of the study. Instruments used in this study included the Family Environment Scale, the Behavior Assessment System for Children the Beck Anxiety Inventory and the Beck Depression Inventory. In addition, the researcher used qualitative analysis to assess contents of family members' and counseling staff's journals, expressive arts products, and family members' evaluations. Results of this exploratory study indicated some improvements in children's, parents' and total family functioning. Expressive arts therapy shows promise in effecting constructive change in bereaved families and is deserving of further research. digital.library.unt.edu/ark:/67531/metadc2861/

Expulsion of Carriers from the Double-Barrier Quantum Well and Investigation of Its Spectral and Transport Consequences
In this work I investigate the expulsion of carriers from nanostructures using the double-barrier quantum well (DBQW) as an example and discuss manifestations of this effect in the spectrum of the DBQW in absence of bias, and in the tunneling current in presence of bias. Assuming equality of the Fermi energy in all regions of the considered system, I compute the relative density of carriers localized in the DBQW and conclude that a fraction of carriers is expelled from this nanostructure. digital.library.unt.edu/ark:/67531/metadc277697/
Extemporizing Reawakened: Saxophonist Branford Marsalis's Approach to the Cadenza for Concertino da Camera for Alto Saxophone and Eleven Instruments by Jacques Ibert
Access: Use of this item is restricted to the UNT Community.
Whether provided by a composer, written out by a performer or completely improvised, the cadenza became a vehicle for performers' creativity, lyricism and technical prowess in the eighteenth and nineteenth centuries. The debate about whether to notate or improvise cadenzas, a question as old as the cadenza itself, continues today. Saxophonists have not been involved in this debate, since the instrument is a product of the mid-nineteenth century and was in its infancy just as the practice of improvising cadenzas was fading. This study documents an unprecedented, recently-recorded, improvised cadenza in one of the most significant twentieth-century saxophone works: Jacques Ibert's Concertino da Camera for Alto Saxophone and Eleven Instruments (1935). Saxophonist Branford Marsalis's neo-cadenza for Ibert's composition presents an aggregate of the twenty-first-century performer improvising a cadenza to a twentieth-century work, in a tradition that was common centuries ago. The document begins with an inquiry into improvised cadenzas, and proceeds to an examination of the performance history of the cadenza for the Concertino da Camera. Twenty professionally-recorded versions of the cadenza are presented in order to understand the performance history of the cadenza, and to place the Marsalis cadenza into context. This research culminates in a transcription and analysis of the cadenza as improvised and recorded by Marsalis. Remarks from a personal interview with Marsalis are also included. digital.library.unt.edu/ark:/67531/metadc5610/

Extended performance techniques and compositional style in the solo concert vibraphone music of Christopher Deane.
Vibraphone performance continues to be an expanding field of music. Earliest accounts of the presence of the vibraphone and vibraphone players can be found in American Vaudeville from the early 1900s; then found shortly thereafter in jazz bands as early as the 1930s, and on the classical concert stage beginning in 1949. Three Pieces for Vibraphone, Opus 27, composed by James Beale in 1959, is the first solo concert piece written exclusively for the instrument. Since 1959, there have been over 690 pieces written for solo concert vibraphone, which stands as evidence of the popularity of both the instrument and the genre of solo concert literature. Christopher Deane has contributed to solo vibraphone repertoire with works that are regarded as staples in the genre. Deane's compositions for vibraphone consistently expand the technical and musical potential of the instrument. Performance of Deane's vibraphone works requires a performer to utilize grips and specific performance techniques that are departures from standard performance practices. Many of the performance techniques needed to successfully execute these pieces are not routinely found in either percussion pedagogy courses or performance ensemble situations. As a result, most percussionists are not familiar with these techniques and will require additional assistance, instruction, or demonstrations. The impetus of this document is to present explanations and solutions for performance areas that require extended performance techniques, to offer recommendations on the creation, choosing, and manipulating of special implements, and to propose varied choices related to artistic interpretation of three of Deane's vibraphone pieces: Mourning Dove Sonnet (1983), The Apocryphal Still Life (1996), and Dis Qui Etude (2004). digital.library.unt.edu/ark:/67531/metadc9030/

Extensions to Jinni Mobile Agent Architecture
We extend the Jinni mobile agent architecture with a multicast network transport layer, an agent-to-agent delegation mechanism and a reflection based Prolog-to-Java interface. To ensure that our agent infrastructure runs efficiently, independently of router-level multicast support, we describe a blackboard based algorithm for locating a randomly roaming agent. As part of the agent-to-agent delegation mechanism, we describe an alternative to code-fetching mechanism for stronger mobility of mobile agents with less network overhead. In the context of direct and reflection based extension mechanisms for Jinni, we describe the design and the implementation of a reflection based Prolog-to-Java interface. The presence of subtyping and method overloading makes finding the most specific method corresponding to a Prolog call pattern fairly difficult. We describe a run-time algorithm which provides accurate handling of overloaded methods beyond Java's reflection package's limitations. digital.library.unt.edu/ark:/67531/metadc2773/

The Extent of Autism Knowledge of Novice Alternatively Certified Special Education Teachers in Texas
An increase in the prevalence rate of autism is not necessarily matched by a concurrent increase in the rate of highly qualified special education teachers. The low ratio of highly qualified teachers to the number of students with autism has resulted in chronic teacher shortages in this area. Alternative certification is used as a mechanism to alleviate the demand for highly qualified teachers in special education. However, alternative certification routes have often left novice teachers underprepared for teaching students with autism, more specifically in the implementation of evidence-based practices necessary for instructional effectiveness. The purposes of the study were: a) to assess the knowledge of novice alternatively certified (AC) teachers in the area of autism education; and b) to determine the extent to which age, credit hours of instruction, formal hours of instruction, amount of professional development, and number of students with autism predict the variance in knowledge scores. Participants included all novice (i.e., first-and second-year) alternatively certified special education teachers in the state of Texas. Data were collected through an electronic survey instrument disseminated state-wide to approximately 33 individuals. Multiple regression was conducted in order to determine the strongest predictors of autism knowledge scores. In addition, a multi-way ANOVA was performed to identify differences between groups. The largest predictor of knowledge of autism was hours engaged in self-directed learning. Overall, AC programs in Texas need to provide basic and core content in the area of autism to increase the knowledge of novice teachers. digital.library.unt.edu/ark:/67531/metadc407790/

Extermination Warfare? The Conduct of the Second Marine Division at Saipan
Historians John W. Dower, Craig Cameron, and Ronald Takaki argue that the Pacific War was a war of extermination fueled by race hate. Therefore, the clash between the military forces of the Japanese Empire and United States of America yielded a "kill or be killed" environment across the battlefields of the Pacific. This work examines the conduct of the Second Marine Division during its campaign of conquest against the Japanese held island of Saipan from June 15, 1944-July 9, 1944. It is based upon traditional military history sources to test their theories in context of the conduct of Marines toward Japanese soldiers and civilians during the Saipan campaign. Did Marines practice a war of extermination or conduct themselves in a humane manner? digital.library.unt.edu/ark:/67531/metadc6098/
External and Internal Influences on Congruence Between Sexual Attitudes and Behavior
The purpose of this study was to examine the hypotheses that the external factors of family environment, gender, and clinical status and the internal factors of self-esteem and impression management would have either a positive influence or a negative influence on individuals' congruence between their sexual attitudes and their sexual behavior. The hypotheses that the external and internal factors would be significant predictors of congruence between sexual attitudes and behavior were not supported by regression analyses. Clinical status and impression management were significant predictors of congruence but in the opposite direction than hypothesized. When age was factored out of the regression equation, clinical status was no longer a significant predictor of congruence. However, impression management remained a significant predictor of congruence. digital.library.unt.edu/ark:/67531/metadc279289/
The External Conflict of Modern War Correspondents: Technology's Inevitable Impact on the Extinction of Nostalgic Combat Reporting
Through historical and content analyses of war coverage, this study qualitatively addresses emotional quality, use of sources, and implied use of technology to better understand the tension between Vietnam and Afghanistan war correspondents and their military counterparts. Early American democracy aspired to give total freedom to its people. But the American military, in its quest to uphold the ideas of democracy, has often challenged the freedom of press clause set forth by the United States Constitution. Since the Vietnam era, the relationship between the military and the media has been plagued by questions of censorship, assertions of falsehood, and threats to national security. But it is the technological advancements in both reporting and combat techniques that have caused a disappearance of the nostalgic war coverage that American correspondents once prospered from. The possibility of returning to journalists' vision of unrestricted press access is all but lost due to such advancements. digital.library.unt.edu/ark:/67531/metadc3247/

Extinction Effects During Assessment and Treatment of Behavior Disorders in Applied Settings
The main and side effects of extinction were evaluated in a multiple baseline design across the problem behaviors of two elementary school boys. For each subject, functional analysis procedures resulted in the occurrence and assessment of only one of several problem behaviors reported by teachers. Extinction treatment based on functional analysis outcomes was then applied to the assessed topography and resulted in the emergence of other inappropriate response forms. Each successive behavior was exposed to extinction and changes in previous and subsequent response forms were observed. Both main effects and indirect effects of extinction were examined. Findings are discussed regarding the covariation of responses and implications for the treatment of behavior disorders in applied settings. digital.library.unt.edu/ark:/67531/metadc279085/

Extra-Musical Associations in Selected Pieces From Années de Pélerinage, Troisième Année, by Franz Liszt: A Lecture Recital, Together with Three Recitals of Selected Works of D. Scarlatti, F.J. Haydn, L.v. Beethoven, F. Schubert, F. Chopin, J. Brahms, R. Schumann, and Others
Volumes one and two of Annees de Pelerinage contain travel impressions. The pieces in volume three serve as a means of expressing a religious pilgrimage. The religiousmeaning is implied by the titles and by letters Liszt wrote concerning specific pieces. For the pieces to have programmatic significance, the music must support the verbal clues. This dissertation maintains that selected pieces in Annees de Pelerinage III are programmatic and that Liszt provided musical clues that have not been discovered or, if noticed, have not been analyzed in detail. Also, the dissertation explores similarities between selected pieces of Annees de Pelerinage III and other programmatic or texted works by Liszt sharing the same subject. The findings reinforce the premise that Liszt deliberately intended to express certain extra-musical ideas within the music itself. The paper briefly analyzes the musical reasons for labeling Annees de Pelerinaae III a cycle. Different sources call these pieces cyclic, citing the shared common religious theme as the reason. This dissertation discusses musical reasons that reinforce the idea of a cycle. Chapter II discusses Liszt's views on program music. Chapter III identifies common themes in Liszt's programmatic works and discusses the symbolic significance of thematic transformation. Chapter IV suggests an approach to analyzing program music. Chapter V discusses Liszt's musical narrative and his use of common rhetorical devices. Chapter VI analyzes extra-musical associations in selected pieces from the Annees de Pelerinaae—Troisieme Annee. Five pieces have been selected for analysis—Anaelus1. Aux Cypres de la Villa d'Este I and II, Marche funebre. and Sursum corda. digital.library.unt.edu/ark:/67531/metadc332359/
