Selected works for solo frame drums by B. Michael Williams. (open access)

Selected works for solo frame drums by B. Michael Williams.

In 1993, American percussionist and composer B. Michael Williams published Four Solos for Frame Drums. This collection is considered the first work written exclusively for solo frame drum in Western notation. Williams primarily modeled his solos around traditional rhythms and techniques from Middle Eastern musical traditions as well as Glen Velez's virtuosic style of playing frame drums. He also drew influence from the music of South India and Sub-Saharan Africa. Williams intentionally combines the aforementioned elements as a means to expose his students and audience members to the music and drumming of these regions. The purpose of this paper is to provide a detailed analysis of select compositions for solo frame drum by B. Michael Williams in order to assist future performers in making well-informed interpretive decisions. The analysis will highlight the compositional style, structural components, technical demands and important performance considerations of four pieces by Williams: Quatrinity, Etude in Arabic Rhythms, Another New Riq and Rhythmic Journey no. 1: (From Conakry to Harare).

Making Sense of Teaching: A Holistic Approach to Teacher Reflection about Practice (open access)

Making Sense of Teaching: A Holistic Approach to Teacher Reflection about Practice

The purpose of this study was to examine the lived experience of reflection and document how a holistic approach to teacher reflection contributes to teachers' understanding of, and improvement in their pedagogical practice. The investigation asked how classroom observations, when followed by a reflective dialogue, impact pedagogical practice. The particular focus included how teachers make sense of observational data during a post-observation, reflective dialogue; how teachers reflect on classroom observational data; and how the holistic reflection experience impacts teachers' pedagogical practice. Three research questions guided this study. How do teachers make sense of observational data during a post observation reflective dialogue? How do teachers reflect on classroom observational data? How might the holistic reflection experience impact teachers' pedagogical practice? Findings from this study provide implications for incorporating the practice of teacher reflection and reflective dialogue as professional development and for educational research.

Selected Songs of Dan Beaty: Background, Analysis, and Performance Guide (open access)

Selected Songs of Dan Beaty: Background, Analysis, and Performance Guide

Dan Beaty (1937-2002) was a prolific composer, pianist, researcher, educator, and writer. His large compositional output included chamber works, choral works, songs, orchestral pieces, electronic music, and keyboard works. Beaty was well versed in traditional Western music as well as the more avant-garde and perplexing idioms of the twentieth century. Beaty's compositions reflect the many fascinating, if not always popular, musical trends of his time. His music encompasses styles from serial to jazz, shows compositional influences from Arnold Schoenberg to Indonesian music, and demonstrates thought-provoking and highly intellectual craftsmanship. This document explores several of Beaty's songs through a discussion of the composer's life and compositional process. Songs included in this document are Three Weeks Songs, October, November, A Sappho Lyric, Love Song, That Night When Joy Began, and War Lyrics. This document was written to accompany the author's DMA Lecture-Recital at the University of North Texas. Unfortunately, Beaty's vocal music was never published and is mostly unknown. One goal of the project was to initiate interest in Beaty's songs. Through this document, Lecture-Recital, and additional performances, considerable strides have been made to bring Beaty's songs to new audiences throughout the United States. In addition, the author has received permission from …

Computational Epidemiology - Analyzing Exposure Risk: A Deterministic, Agent-Based Approach (open access)

Computational Epidemiology - Analyzing Exposure Risk: A Deterministic, Agent-Based Approach

Many infectious diseases are spread through interactions between susceptible and infectious individuals. Keeping track of where each exposure to the disease took place, when it took place, and which individuals were involved in the exposure can give public health officials important information that they may use to formulate their interventions. Further, knowing which individuals in the population are at the highest risk of becoming infected with the disease may prove to be a useful tool for public health officials trying to curtail the spread of the disease. Epidemiological models are needed to allow epidemiologists to study the population dynamics of transmission of infectious agents and the potential impact of infectious disease control programs. While many agent-based computational epidemiological models exist in the literature, they focus on the spread of disease rather than exposure risk. These models are designed to simulate very large populations, representing individuals as agents, and using random experiments and probabilities in an attempt to more realistically guide the course of the modeled disease outbreak. The work presented in this thesis focuses on tracking exposure risk to chickenpox in an elementary school setting. This setting is chosen due to the high level of detailed information realistically available to …

Effects of Triclosan, Triclocarban, and Caffeine Exposure on the Development of Amphibian Larvae. (open access)

Effects of Triclosan, Triclocarban, and Caffeine Exposure on the Development of Amphibian Larvae.

Triclosan and triclocarban are antimicrobials found in numerous consumer products, while caffeine is the most commonly consumed stimulant by humans. This study was undertaken to determine the effects of triclosan, triclocarban, and caffeine on the development and physiology of amphibian larvae. LC50 values of triclosan and triclocarban were determined after 96 hours for three North American larval species: Acris crepitans blanchardii, Bufo woodhousii woodhousii, Rana sphenocephala, and for a common amphibian developmental model: Xenopus laevis. Amphibian larvae were most sensitive to triclosan and triclocarban exposure during early development based upon 96-hour LC50 values. Heart rates for X. laevis and North American larvae exposed to triclosan were variable throughout development. However, significantly lower heart rates were observed in all larvae exposed to triclocarban. Metabolic rates of X. laevis and R. sphenocephala larvae exposed to triclosan were significantly affected in larvae exposed to ½ LC50 and the LC50 concentration. Metabolic rates of X. laevis larvae exposed to triclocarban were significantly affected by exposure to ½ LC50 concentrations in three of four stages investigated. No significant differences were observed in North American larvae exposed to triclocarban. Tissue uptake, lipid uptake, tissue bioconcentration factor (BCF) and lipid BCF of triclosan and triclocarban were investigated …

Impacts of Blogging Motivation and Flow on Blogging Behavior (open access)

Impacts of Blogging Motivation and Flow on Blogging Behavior

With the development of free and easy-to-use software programs, blogging has helped turn Web consumers into Web content providers. Blogging provides distinctive insight into comprehending e-consumer behavior explicitly with respect to social networking and information searching behaviors while facilitating a state of flow. The objectives of this study are to identify determinant dimensions of blogging motivations and flow, and to investigate the hypothesized relationships of the motivational blogging behavior. Analyzing data (n = 432) from a southwestern university, results reveal the critical dimensions of motivations, behaviors, and flow in blogging. Upon extending Hoffman and Novak's (1996) flow model, 14 out of 26 hypotheses were confirmed regarding the significant impacts of blogging motivations and flow on blogging behaviors. The findings revealed that the desire for information, enjoyment, and loyalty are the primary drivers for experiential blogging behavior. Specifically, information-seeking is the decisive motivation to urge experiential and e-shopping behavior concurrently. This study shows that indulgence and telepresence in flow might play pivotal mediating roles to promote the goal-oriented e-shopping behavior resulting enjoyment and loyalty-seeking motivations.

Grayson County, Texas, in Depression and War: 1929-1946 (open access)

Grayson County, Texas, in Depression and War: 1929-1946

The economic disaster known as the Great Depression struck Grayson County, Texas, in 1929, and full economic recovery did not come until the close of World War II. However, the people of Grayson benefited greatly between 1933 and 1946 from the myriad spending programs of the New Deal, the building of the Denison Dam that created Lake Texoma, and the establishment of Perrin Army Air Field. Utilizing statistical data from the United States Census and the Texas Almanac, this thesis analyzes the role of government spending‐federal, state, and local‐in the economic recovery in Grayson County.

The Debate over the Corporeality of Demons in England, c. 1670-1700 (open access)

The Debate over the Corporeality of Demons in England, c. 1670-1700

According to Walter Stephens, witch-theorists in the fifteenth century developed the witchcraft belief of demon copulation in order to prove the existence of demons and therefore the existence of God. In England, during the mid-seventeenth century, Cartesian and materialist philosophies spread. These new philosophies stated there was nothing in the world but corporeal substances, and these substances had to conform to natural law. This, the philosophers argued, meant witchcraft was impossible. Certain other philosophers believed a denial of any incorporeal substance would lead to atheism, and so used witchcraft as proof of incorporeal spirits to refute what they felt was a growing atheism in the world. By examining this debate we can better understand the decline of witchcraft. This debate between corporeal and incorporeal was part of the larger debate over the existence of witchcraft. It occurred at a time in England when the persecution of witches was declining. Using witchcraft as proof of incorporeal substances was one of the last uses of witchcraft before it disappeared as a valid belief. Therefore, a better understanding of this debate adds to a better understanding of witchcraft during its decline.

Finding the perfect blend: A comparative study of online, face-to-face, and blended instruction. (open access)

Finding the perfect blend: A comparative study of online, face-to-face, and blended instruction.

As distance learning evolved, course designers and teachers quickly recognized the value of integrating online features into the classroom. The result was blended learning, a combination of online and face-to-face components. This complex and dynamic new form of education has raised many questions about the role of computer-mediated communication in education and has provided new opportunities for extending research in learning and communication. The purpose of the study was to determine whether a blended class will produce different (and possibly better) results in terms of student perceptions of the overall learning experience and student satisfaction than traditional lecture-based face-to-face instruction or learning that is delivered entirely online. The main goals of this study were to compare the effectiveness of face-to-face, online, and blended instruction, and to examine the role of interactions in the effectiveness of each educational method. While each form of instruction received very positive feedback from both students and instructors and the newly introduced blended courses proved very successful in terms of overall satisfaction with the learning experience, the traditional lecture-based courses produced more positive attitudes toward the subject matter. The possible causes of these discrepancies between some of the quantitative and qualitative results point toward the role …

Links among perceived service quality, patient satisfaction and behavioral intentions in the urgent care industry: Empirical evidence from college students. (open access)

Links among perceived service quality, patient satisfaction and behavioral intentions in the urgent care industry: Empirical evidence from college students.

Patient perceptions of health care quality are critical to a health care service provider's long-term success because of the significant influence perceptions have on customer satisfaction and consequently organization financial performance. Patient satisfaction affects not only the outcome of the health care process such as patient compliance with physician advice and treatment, but also patient retention and favorable word-of-mouth. Accordingly, it is a critical strategy for health care organizations to provide quality service and address patient satisfaction. The urgent care (UC) industry is an integral part of the health care system in the United States that has been experiencing a rapid growth. UC provides a wide range of medical services for a large group of patients and now serves an increasing population. UC is becoming popular because of the convenient locations, extended hours, walk-in policy, short waiting times, and accessibility. A closer examination of the current health care research, however, indicates that there is a paucity of research on urgent care providers. Confronted with the emergence of the urgent care industry and the increasing demand for urgent care, it is necessary to understand how patients perceive urgent care providers and what influences patient satisfaction and retention. This dissertation addresses four …

A Verilog 8051 Soft Core for FPGA Applications (open access)

A Verilog 8051 Soft Core for FPGA Applications

The objective of this thesis was to develop an 8051 microcontroller soft core in the Verilog hardware description language (HDL). Each functional unit of the 8051 microcontroller was developed as a separate module, and tested for functionality using the open-source VHDL Dalton model as benchmark. These modules were then integrated to operate as concurrent processes in the 8051 soft core. The Verilog 8051 soft core was then synthesized in Quartus® II simulation and synthesis environment (Altera Corp., San Jose, CA, www.altera.com) and yielded the expected behavioral response to test programs written in 8051 assembler residing in the v8051 ROM. The design can operate at speeds up to 41 MHz and used only 16% of the FPGA fabric, thus allowing complex systems to be designed on a single chip. Further research and development can be performed on v8051 to enhance performance and functionality.

Rete Mirabile: An Installation (open access)

Rete Mirabile: An Installation

Rete Mirabile is my new installation piece combining scientific principles with live computer generated music. The title is a Latin term meaning "Wonderful Net," which I use to refer to the highly convoluted network of biological data that drives my installation. The sonification of data, computer modeling of biological processes, kinetic sculptures, and user interactivity are central parts of the installation. The paper is organized as follows: First, brief history of the forerunners that inspired my work is given. This includes a short discussion on how John Cage and David Tudor influenced current artists works, and how those works have influenced my own work. Then I review current installation works that share similarities with my own. Finally, a detailed discussion and analysis of the construction and function concludes the paper.

Using Diffusion of Innovations to Explore Digital Gaming in Undergraduate Library Instruction (open access)

Using Diffusion of Innovations to Explore Digital Gaming in Undergraduate Library Instruction

Digital games and simulations are receiving considerable notice within the Library and Information Science (LIS) community. This study adds to the depth of knowledge in this area by providing research on the likelihood a hypothetical digital game delivery method for library instruction achieves sufficient adoption to justify its development. Furthermore, this knowledge will assist decision making processes for individuals debating the current or potential role of digital gaming at their institutions. In this mixed methods study, over 300 undergraduates were surveyed about their technology preferences, including digital gaming, for delivery of two forms of academic library instruction. The two forms of library instruction were (a) providing users with spatial information on physical library layout, and (b) educating users on information literacy topics and skills. Observational data was collected during the survey sessions, occurring at face-to-face library instruction sessions. Self-selected survey participants were also interviewed to further probe their survey responses. Rogers' Diffusion of Innovations was the theoretical foundation to this research. The primary innovation of study was the digital game delivery method. Detailed analysis of the survey-based data set included three nonparametric scaling methods: 1) rank-sum scaling; 2) circular triad analysis; and 3) multidimensional preference mapping. Content analysis of the …

Accident versus Essence:  Investigating the Relationship Among Information Systems Development and Requirements Capabilities and Perceptions of Enterprise Architecture (open access)

Accident versus Essence: Investigating the Relationship Among Information Systems Development and Requirements Capabilities and Perceptions of Enterprise Architecture

Information systems (IS) are indelibly linked to the global economy and are indispensable to society and organizations. Despite the decisive function of IS in organizations today, IS development problems continue to plague organizations. The failure to get the system requirements right is considered to be one of the primary, if not the most significant, reasons for this high IS failure rate. Getting requirements right is most notably identified with Frederick Brooks' contention that requirements are the essence of what IT professionals do, all the rest being accidents or risk management. However, enterprise architecture (EA) may also provide the discipline to bridge the gap between effective requirements, organizational objectives, and the actual IS implementations. The intent of this research is to examine the relationship between IS development capabilities and requirements analysis and design capabilities within the context of enterprise architecture. To accomplish this, a survey of IT professionals within the Society for Information Management (SIM) was conducted. Results indicate support for the hypothesized relationship between IS development and requirements capabilities. The hypothesized relationships with the organizational demographics were not supported nor was the hypothesized positive relationship between requirements capabilities and EA perceptions. However, the nature of the relationship of requirements and …
