D. A. Kolb’s Theory of Experiential Learning: Implications for the Development of Music Theory Instructional Material (open access)

D. A. Kolb’s Theory of Experiential Learning: Implications for the Development of Music Theory Instructional Material

This research project evaluates the effectiveness of specific music theory instructional strategies in terms of D. A. Kolb’s theory of experiential learning and Kolb’s typology of individual learning style. The project provides an original methodology for the adaptation of music theory instructional material to the individual learning style types described in Kolb’s typology. The study compares the relative effectiveness of two music theory instructional sequences, one of which is adapted for all of the learning style modalities described in Kolb’s typology, and the other adapted for only a limited number of Kolb’s learning style types. In order to compare the potential “learning outcomes” produced by these instructional sequences, a detailed study is proposed, in which computer based instruction (CBI) will deliver the instructional sequences to research participants and electronically record the participants’ responses. The current study demonstrates the effective aspects of the original methodology and suggests methods for the successful adaptation of music theory instructional material to individual student learning styles.

Abstract Moments of Art Found in the Ordinary (open access)

Abstract Moments of Art Found in the Ordinary

This paper is an experiment using digital video to locate and identify the abstract in everyday life and nature. The abstract moment occurs when the image that is captured by video loses its connection with the original context, allowing the images to be viewed in an entirely new way. The abstract moment is initiated by a transformative instant, that instant in which perception is altered and the viewer sees the intended content of composition of light and sound. The project contains four digital videos that record the artist's progress and interests.

Activating Space within the Object and the Site (open access)

Activating Space within the Object and the Site

I look at the world as a sculptor, examining physical constructs and implied meanings. My current research developed from my earlier studies of “containment” or, more specifically, “encapsulation,” creating visual, often physical, boundaries around selected content. Encapsulation confers a more active role than “containment”, a process rather than a result. This idea speaks to the issues of form, and asks the viewer to question the outside “shape of the form” in relation to the inside shape and content. My work focuses on exposed interior spaces and forms, allowing the viewer to enter the space physically as well as mentally and psychologically. Built in a large enough scale, the viewer could actually become the content. The sculpture’s interpretation revolves around the seen as well as the unseen. I built this duality into my work by using transparent and opaque materials. I also implemented small diameter stainless steel rod along with the transparent and opaque vinyl to reduce forms to their respective shapes and volumes. This approach allowed me to clean the “slate” of an object’s collective meaning and context, adapting it to the intent of my work.

ADA Tasking Facilities for Concurrent and Real-Time Programming (open access)

ADA Tasking Facilities for Concurrent and Real-Time Programming

This paper describes multitasking facilities of Ada in concurrent and real-time programming. Synchronization and process communication mechanisms are discussed in detail, also, a new mechanism to solve the scheduling problem is developed. In the concurrent programming aspect, a comparison is made between Ada's rendezvous and Pascal's Monitor concept. In the real-time programming aspect, the differences between the Ada multitasking and the traditional "cyclic executive approaches are contrasted and their associated costs/benefits analyzed.

Adapting Reproduction Knowledge and Photomechanical Techniques to Serigraphy for Non-Commercial Purposes (open access)

Adapting Reproduction Knowledge and Photomechanical Techniques to Serigraphy for Non-Commercial Purposes

This problem is involved with attempting to answer two basic questions: (a) Can I, a commercial artist, expand and develop as an artist through screen printing and make valid aesthetic statements unrelated to client and/or product? and (b) Can knowledge of reproduction methods and photo-mechanical techniques be successfully utilized in screen printing for non-commercial purposes? Extensive notes in the form of a journal were maintained as work on the project progressed. These notes, combined with the completed prints, were the sources of data for this paper.

Adding and Subtracting Color in the Painting and Serigraphic Processes: A Development of Consistency in Two Art Media (open access)

Adding and Subtracting Color in the Painting and Serigraphic Processes: A Development of Consistency in Two Art Media

This is a method in which designs as a whole are not pre-planned or pre-arranged, but are developed by applying layers of color. This is an additive method for obvious reasons, and it is subtractive because shapes can be covered with opaque paint or very intense stain. Transparent layers of color applied over existing colors cause hue changes, and the process creates subtleties resulting from one color showing through another.

Adherence and Haemagglutination of Moraxella Catarrhalis.

Access: Use of this item is restricted to the UNT Community
M. catarrhalis is a gram-negative diplococci frequently associated with infections of the upper respiratory tract. During the past decade, some preliminary studies have attempted to elucidate mechanisms of adherence and haemagglutination of M. catarrhalis. These studies have reported, in many cases, inconsistent results. There are two purposes of this research. First, identify mechanisms that may potentially be associated with the adherence and haemagglutination of M. catarrhalis. Second, suggest research directions that may be fruitful in clarifying these mechanisms.

Advance Directives in Texas: Advance Directives Act of 1999 (open access)

Advance Directives in Texas: Advance Directives Act of 1999

Growth in the number of people living to very old age and progress in health care technology are creating important new challenges for our society. Among them is modern medicine's ability to extend some people's lives beyond the point where they are capable of making decisions or expressing their needs and desires, resulting in the very complex problem of knowing when to allow a person to die. In part, advance directives were created to solve this problem. Texas has been busy developing changes to existing state laws in an effort to create more "user-friendly" directives. This paper explores the history of advance directives, and discusses the details and nuances of the Texas Advance Directives Act of 1999.

Agent-Based Architecture for Web Deployment of Multi-Agents as Conversational Interfaces. (open access)

Agent-Based Architecture for Web Deployment of Multi-Agents as Conversational Interfaces.

Agent-based architecture explains the rationale and basis for developing agents that can interact with users through natural language query/answer patterns developed systematically using AIML (artificial intelligence mark-up language) scripts. This thesis research document also explains the architecture for VISTA (virtual interactive story-telling agents), which is used for interactive querying in educational and recreational purposes. Agents are very effective as conversational interfaces when used along side with graphical user interface (GUI) in applications and Web pages. This architecture platform can support multiple agents with or with out sharing of knowledgebase. They are very useful as chat robots for recreational purposes, customer service and educational purposes. This platform is powered by Java servlet implementation of Program D and contained in Apache Tomcat server. The AIML scripting language defined here in is a generic form of XML language and forms the knowledgebase of the bot. Animation is provided with Microsoft® Agent technology and text-to-speech support engine.
