The purpose of this ethnographic case study was to explore how different distance learning modes and environments affect the design and implementation of a crosscultural, university-level, distance education course. The case chosen was a U.S. -Taiwan collaboration that used H.323 videoconferencing and Web 2.0 technologies. Through participant observation, document analysis and interview, this study investigated the factors that influence the instructor's pedagogical practice with new technologies in relation to the cross-cultural aspects. It also examined the various types of interactions that occurred as consequences of the distance learning modes and the contexts of the course. The findings provided a portrait of factors and relationships that affected the implementation of the curriculum and the enablement of technology affordances. They suggested that the instructor’s personal value and intrinsic motivation, well-supported technology framework, and a long stable international partnership helped sustain her engagement in cross-cultural distance education (CCDE). While the instructor’s high self-efficacy prompted her to idealize technology affordances in the CCDE course, her limited technology literacy hindered the enablement of these affordances and resulted in different outcomes. In addition, difference in the teaching styles between the instructor and her international partner, unbalanced learner preparedness, and the Western valueladen learning environment were also factors that contributed to the gap between the idealization and the realization of the CCDE course. Implications and suggestions for future practice and research were provided in relation to the literature, as well as the contexts of cross-cultural/international distance education. / Access to thesis and accompanying PDF permanently restricted to Ball State community only / Department of Educational Studies

As increasing numbers of baby boomers enter retirement age, Georgia senior centers will be inundated with more computer-savvy seniors than ever before. Web-based nutrition education is a pragmatic option to complement the traditional classroom nutrition education sometimes hindered by the centers’ limited monetary and personnel resources. This exploratory observational study sought to pilot test a companion to classroom nutrition education, a prototype Dietary Approaches to Stopping Hypertension (DASH) diet website, for future implementation in Georgia senior centers. Classroom DASH diet lessons were designed and pilot tested on a convenience sample of community dwelling older adults in 6 metropolitan area centers (n=109). Next, the same lessons were incorporated into a senior-friendly DASH diet website specially designed to meet the needs of older adults and pilot tested on a second convenience sample in one center (n=5). Descriptive and analytical statistics were used to compare baseline and post-website blood pressures, body weights, and DASH-related nutrition knowledge. There was a significant difference in the scores for systolic blood pressure at baseline (M=145.60, SD=8.385) and post-website (M=136.40, SD=9.607) conditions; t(4)=3.74, p =.020. Diastolic blood pressure and weight showed no significant change. A survey of DASH-related knowledge, behaviors, and beliefs showed movement towards desired responses on 44% of survey questions after the intervention. An opinion survey collected seniors’ perspectives on their website experience. 100% of participants reported satisfaction with the website and willingness to continue using it. Refinements to the alpha-prototype website are recommended before further testing with a larger pilot study group. Although expanded research is necessary, results from this limited pilot test suggest that web-based nutrition education is a promising method to reinforce classroom lessons teaching dietary and lifestyle management of hypertension in Georgia senior centers. Multi-component nutrition education holds potential to address diversity in cultures, learning preferences, and functional limitations of Georgia seniors.

En esta tesis presentamos un nuevo enfoque para concebir, diseñar y desarrollar aplicaciones web accesibles usando conceptos de la Orientación a Aspectos. Con el fin de alcanzar nuestro objetivo, proveemos algunas técnicas de modelado que desarrollamos explícitamente para manejar las características no-funcionales, genéricas y transversales de la accesibilidad. Concretamente, enriquecimos la técnica UID con puntos de integración para registrar los intereses de accesibilidad que serán considerados en el diseño de la interfaz de usuario. Luego, instanciando la plantilla SIG con tablas de asociación, trabajamos en el modelo de interfaz abstracta con softgoals de accesibilidad para obtener un modelo de interfaz concreta y accesible de la aplicación web en desarrollo. Para ilustrar nuestras ideas y señalar las ventajas de una clara separación de intereses durante el ciclo de vida de desarrollo, utilizamos un ejemplo de aplicación real. De esta manera, nuestra propuesta se fundamenta en técnicas de diseño reconocidas, las cuales hemos embebido en una herramienta de software, con el propósito de facilitar la transferencia del enfoque a la industria. <i>(del texto de la contratapa)</i> / Tesis doctoral de la Facultad de Informática (UNLP).

El presente trabajo surge como una necesidad en el Campus de la Universidad Nacional de Salta, de contar con herramientas que faciliten al Ingeniero de redes realizar tareas de administración desde cualquier punto de la red, independizándolo de esta manera de la plataforma necesaria para ejecutar aplicaciones de gestión. La Administración o Gestión basada en Web es la aplicación de la tecnología World Wide Web a redes y administración de dispositivos. Pretende aprovechar la amplia difusión de los navegadores como interfaz de usuario universal, para utilizarlos como interfaz para las aplicaciones de gestión. Debido a que esta tecnología es relativamente nueva, pocos investigadores se adentraron en el tema hasta ahora. El principal beneficio de los mecanismos de Gestión basados en Web es que los desarrolladores de aplicaciones no tienen por qué conocer los detalles de los protocolos de gestión para manejar dispositivos remotos. Adicionalmente esto permite abstraer los diferentes protocolos y unificarlos con una única visión. Este trabajo plantea por una parte inspeccionar el área de la Gestión basada en Web, y compararla con las Herramientas de Gestión tradicionales basadas en SNMP. Se hace énfasis en muchas características como seguridad, eficiencia, costo, interfaz amigable, etc. Por otro lado intenta desarrollar un conjunto de herramientas que sean rápidamente implementables y permitan al Ingeniero de red realizar algunas operaciones de administración en agentes del tipo pc/routers, ver estadísticas, estado y evolución de estos dispositivos.
