Critical Theory and Preservice Art Education: One Art Teacher Educator's Journey of Equipping Art Teachers for Inclusion.

Description: This qualitative action research study examines how critical theory defined and guided my practice as an art teacher educator while I provided inclusion training for seven preservice art teachers during their student teaching. Sources of data included a personal journal, the inclusion curriculum I created for the preservice teachers and questionnaires and interviews. Primary findings indicated that critical theory had a substantive impact on the evolving development of my teaching philosophy, in particular my attention to issues of power redistribution in the classroom and my developing notion of teaching as form of artistry. The findings of this study also indicate that the primary impact of critical theory upon the preservice teachers was the articulation of their personal narratives and its relation to the development of their teaching identities. Further, mentoring these preservice art teachers in critical theory increased their competence in solving educational dilemmas. A primary finding of this study was how significant of a role the supervising or mentor teacher plays in developing preservice teachers' identity. As this is acknowledged, valued and utilized, more collaborative relationships among these stakeholders in the education of the preservice art teacher can be forged. The study provides implications for art teacher educators as they provide inclusion training to preservice teachers. These include honoring narratives, articulating a broader notion of inclusion, and using context-specific instructional tools while preservice teachers are completing fieldwork with students with disabilities. One suggestion for future research is to conduct longitudinal studies which explore and validate the impact of critical theory upon art teacher educators and preservice art teachers during the student teaching semester and several years beyond.

Preserving Access to Government Websites: Development and Practice in the CyberCemetery

Description: This paper discusses the development and practice in the CyberCemetery. In the late 1990's, online U.S. government information was appearing and disappearing at a rapid pace. In 1999, the University of North Texas Libraries (UNT) formed a partnership with the U.S. Government Printing Office (GPO) to address this issue by archiving electronic government websites. This archive, known as the CyberCemetery, provides permanent public access to the websites and publications of defunct U.S. government agencies and commissions. This partnership between UNT and GPO has expanded to include the National Archives and Records Administration (NARA). This paper covers the CyberCemetery's development and the process of identifying, capturing, and publishing content in the archive.

A Comparative Analysis of Minoru Miki's Time For Marimba and Concerto for Marimba and Orchestra

Description: Minoru Miki's first two marimba compositions, Time for Marimba (1968) and Concerto for Marimba and Orchestra (1969) were composed at a revolutionary time-period for the marimba. Due to unique and innovative compositional techniques, Miki helped establish the marimba as a true concert instrument capable of performing music of the highest quality. As a pioneer in composing for marimba literature, Miki was able to capture the true essence of the marimba; a timeless quality that has helped Time for Marimba remain a part of the standard solo repertoire for the past forty years. The purpose of this study is to analyze and compare Minoru Miki's compositions, Time for Marimba and Concerto for Marimba and Orchestra. Composed within a year of each other, these works possess similar compositional techniques, and rhythmic and thematic relationships. This thesis includes a formal analysis and detailed comparisons of compositional techniques used in both works. Performance considerations, a brief biographical sketch of Miki and historical significance of Time for Marimba and Concerto for Marimba and Orchestra are also included.

Louder and Stronger? The Role of Signaling and Receptivity in Democratic Breakdowns and Their Impact Upon Neighboring Regimes

Description: The purpose of this thesis is to establish what specific forces influence whether or not a democratic setback within one nation will diffuse to peripheral states. Past studies devoted to this topic have largely suggested that diffusion essentially functions like a contagious disease, where the likelihood of "infection" is primarily based upon the level of interaction between states. This thesis however proposes that the interaction of the signal generated from a democratic state's collapse and the receptiveness of neighboring nations to this signal ultimately determines when and where diffusion will occur. In order to test the validity of this thesis' claims, the level of democracy within the neighboring states of all failed democratic governments spanning the years 1842-2002 are examined during the first years following such system breakdowns within a large-N quantitative research design. Ultimately this study leads to the conclusion that the interaction of signals and receptivity play a major role in the diffusion of democratic setbacks.

Observing and Attending in a Delayed Matching-to-Sample Preparation in Pigeons

Description: Pigeons worked in a titrating delay match-to-sample (TDMTS) procedure in which selecting the correct comparison stimulus increased the delay between sample offset and comparison-array onset and incorrect comparison selections decreased that delay. Prior research in our lab has shown that the stable adjusted value of the retention interval is a curvilinear function of the observing response requirement. The current study examined the effect of the distribution and predictability of observing response requirements on adjusted retention interval values. The data show that unpredictable observing response requirements were more effective in attenuating the deleterious effects of delay on matching accuracy. The data have implications for our understanding of attending and encoding in performances involving remembering over short temporal durations.

The representation of national political freedom on web interface design: A comparison of government-based and business-oriented websites.

Description: The purpose of this study is to explore the representation of national political freedom on web interface design by using power distance, one of the culture dimensions identified by Geert Hofstede, as a measurement. This study also aims to determine if there are any differences between government-based websites and business-oriented websites in representing national political freedom. A pilot study was conducted to validate ten power distance indicators identified from previous research on cultural dimensions with the intent of establishing a measurement for determining a country's national political freedom on web content and interface design. The result showed that six out of ten proposed indicators are valid power distance indicators. The seventh indicator, symmetric layout, demonstrated that its Web representation correlates with national political freedom level. Consequently, the principal research applied these seven indicators in coding 312 websites selected from 39 countries and analyzed national political freedom represented on these websites with content analysis method. The result of two-way analysis of variance (ANOVA) indicated that large differences exist in web interface design, which in turn reflects the aforementioned national political freedom. The research showed that the mean effect of freedom level between free-country group, partly-free-country group and not-free-country group was statistically significant (p = .003). So was the mean effect of website type between government-based and business-oriented websites (p = .000). Furthermore, the interaction between the freedom level and website type was also significant (p = .041). Therefore, we conclude that web interface design represents a country's political freedom and government-based websites embody more of a nation's authority and supremacy than business-oriented websites do. It is expected that this study furthers our exploration in culture dimensions on web interface design and advances our knowledge in sociological and cultural studies of the web.

Metallization and Modification of Low-k Dielectric Materials

Description: Aluminum was deposited onto both Teflon AF and Parylene AF surfaces by chemical vapor deposition of trimethylaluminum. This work shows that similar thin film (100 Angstroms) aluminum oxide adlayers form on both polymers at the low temperature dosing conditions used in the studies. Upon anneal to room temperature and above, defluorination of the polymer surfaces increased and resulted in fluorinated aluminum oxide adlayers; the adlayers were thermally stable to the highest temperatures tested (600 K). Angle-resolved spectra showed higher levels of fluorination toward the polymer/adlayer interface region. Copper films were also deposited at low temperature onto Teflon AF using a copper hexafluoroacetylacetonate-cyclooctadiene precursor. Annealing up to 600 K resulted in the loss of precursor ligands and a shift to metallic copper. As with aluminum adlayers, some polymer defluorination and resulting metal (copper) fluoride was detected. Parylene AF and polystyrene films surfaces were modified by directly dosing with water vapor passed across a hot tungsten filament. Oxygen incorporation into polystyrene occurred exclusively at aromatic carbon sites, whereas oxygen incorporation into parylene occurred in both aromatic and aliphatic sites. Oxygen x-ray photoelectron spectra of the modified polymers were comparable, indicating that similar reactions occurred. The surface oxygenation of parylene allowed enhanced reactivity toward aluminum chemical vapor deposition. Silicon-carbon (Si-Cx) films were formed by electron beam bombardment of trimethylvinylsilane films which were adsorbed onto metal substrates at low temperatures in ultra-high vacuum. Oxygen was also added to the films by coadsorbing water before electron beam bombardment; the films were stable to more than 700 K, with increasing silicon-oxygen bond formation at elevated temperatures. Copper metal was sputter deposited in small increments onto non-oxygenated films. X-ray photoelectric spectra show three-dimensional copper growth (rather than layer-by-layer growth), indicating only weak interaction between the copper and underlying films. Annealing at elevated temperatures caused coalescence or growth ...

Penile plethysmography: Validation with a juvenile sex offending population.

Description: Traditionally, juvenile sex offenders have been ignored in the literature. More recently the research has expanded particularly in the area of assessment and treatment. This study focused on the assessment of sexual arousal to deviant stimuli using the penile plethysmography (PPG) since it likely plays a significant role in juvenile sex offending behaviors. The goal of this study assessed its validity and reliability using Becker et al.'s set of PPG scenarios with a population of juvenile sex offenders. Significant differences were found between groups of (a) admitters versus partial admitters and (b) offenders with and without male victims. This study also examined the latent structure of the PPG results and found three dimensions: arousal to male stimuli, arousal to females and paraphilias, and arousal to non-sexual acts. These findings provide important implications for assessment of juvenile sex offenders and add to the clinical utility of PPG assessments.

Teaching Simple Auditory Discriminations to Students with Autism

Description: This study aimed to test the effectiveness of classroom translations of some laboratory procedures for teaching simple auditory discriminations to learners with developmental disabilities. Three participants with autism and mental retardation were trained to make topographically distinct responses in the presence of two different stimuli, either a pure tone and silence, or two tones. A portable electronic piano keyboard was used to produce tones. Delayed prompt and differential reinforcement procedures were used to teach the responses. None of the participants performed the discriminations accurately without prompting despite numerous revisions to the procedures.

Hardware and Software Codesign of a JPEG2000 Watermarking Encoder

Description: Analog technology has been around for a long time. The use of analog technology is necessary since we live in an analog world. However, the transmission and storage of analog technology is more complicated and in many cases less efficient than digital technology. Digital technology, on the other hand, provides fast means to be transmitted and stored. Digital technology continues to grow and it is more widely used than ever before. However, with the advent of new technology that can reproduce digital documents or images with unprecedented accuracy, it poses a risk to the intellectual rights of many artists and also on personal security. One way to protect intellectual rights of digital works is by embedding watermarks in them. The watermarks can be visible or invisible depending on the application and the final objective of the intellectual work. This thesis deals with watermarking images in the discrete wavelet transform domain. The watermarking process was done using the JPEG2000 compression standard as a platform. The hardware implementation was achieved using the ALTERA DSP Builder and SIMULINK software to program the DE2 ALTERA FPGA board. The JPEG2000 color transform and the wavelet transformation blocks were implemented using the hardware-in-the-loop (HIL) configuration.

Learner use of French second-person pronouns in synchronous electronic communication.

Description: This study analyzes students' use of the French second-person pronouns tu (T) and vous (V) in small-group (2-3 students) inter-learner online chat sessions. The influence of internal linguistic factors (i.e., turn type and morphosyntactic environment) on learners' appropriate vs. inappropriate use of these pronouns is considered. The study also investigates the influence of Instructional Level on tu-vous use and the extent to which students from different instructional levels provide various types of peer assistance (e.g., lexical, morphosyntactic, and sociolinguistic/pragmatic) . Pronoun use was extremely unstable for learners of all levels, and a Kruskal-Wallis analysis revealed that Instructional Level did not significantly affect appropriate T/V use overall. Instructional Level and Syntax did, however, significantly affect interrogative T/V use, as shown through multivariate analyses. Peer-assisted performance was limited to lexical retrieval. Pedagogical recommendations are presented for teaching and learning second-person pronouns in French.

A Performance Guide and Theorical Study of Keiko Abe's Marimba d'Amore and Prism Rhapsody for Marimba and Orchestra

Description: Keiko Abe's contributions to the contemporary marimba repertoire have been a milestone in the development of the marimba as a solo concert instrument. Besides the creation of a new repertoire through commissions and her own compositions, Abe's contributions to the marimba include the improvement of the sound quality of the marimba and the establishment of the five octave instrument as the standard concert marimba. During the last four decades, Abe's compositions have been performed and studied worldwide and become standard literature for the marimba. Abe has written more than sixty compositions for marimba, including concertos, duets and solo pieces. The goal of this dissertation is to provide a comprehensive method for the performance and preparation of two major Keiko Abe's compositions, Marimba d'Amore composed by Abe in 1998 and Prism Rhapsody for Marimba and Orchestra composed in 1996. This dissertation will discuss theoretical as well as performance issues related to these two compositions. Each piece is discussed with regard to its distinctive compositional approach and inherent performances issues. In order to provide the reader an explanation of the compositional procedures used by Abe, specific directions for the performance and preparation of these two works are offered.

Lowest of the Low: Scenes of Shame and Self-Deprecation in Contemporary Scottish Cinema

Description: This thesis explores the factors leading to the images of self-deprecation and shame in contemporary Scottish film. It would seem that the causes of these reoccurring motifs may be because the Scottish people are unable to escape from their past and are uneasy about the future of the nation. There is an internal struggle for both Scottish men and women, who try to adhere to their predetermined roles in Scottish culture, but this role leads to violence, alcoholism, and shame. In addition, there is also a fear for the future of the nation that represented in films that feature a connection between children and the creation of life with the death of Scotland's past. This thesis will focus on films created under a recent boom in film production in Scotland beginning in 1994 till the present day.
