[Abstract]: Advances in computer technology and communication technology have been revolutionary during the latter half of the last century. During which, computer technology has transformed the world from the industrial age to the information age. Computer technology by its very nature is a new and intriguing phenomenon to work with. In contrast, nursing by its very nature is an older and most trusted profession to be part of. Uncovering the secrets of combining this media and that profession then became the challenge for the study. The foundations for the study are set within the qualitative model of phenomenology, where the methods are based on the work of van Manen (1997). This framework was used to explore a deeper understanding of the nursing experience with computer technology in the hospital ward. The objectives of the study were primarily to understand computer technology within the social context of nursing and secondly, other objectives were to explore the dynamics, between computer technology and the culture of nursing. Discussion was invited on the positive and negative influences of computer technology as experienced by these nurses.This was achieved by working with nurses in a variety of ward settings including a rural base hospital, as they participated in a series of in-depth, unstructured interviews. The data they provided reflects that computer technology has the potential to impact on the structure and delivery of healthcare, challenge the traditional roles and scope of practice, alter the existing boundaries and relationships and reinvent the clinical environment of nursing.

An 8 bit microcontroller slave unit was designed, constructed, and tested to demonstrate advantages and feasibility of master/slave parallel processing using conventional processors and relatively slow inter-processor communications. An 8 bit ISA bus controlled by an 80X86 is interfaced to a logic block that controls data flow to and from the slave processors. The slave processors retrieve tasks sent by the master processor and once completed, return results to the master that are buffered for the master's retrieval. The task message sent to the slave processors has task description and task parameters. The master has access to the bi-directional buffer and a status byte for each slave processor. Considerable effort is made to allow the hardware and software architecture to be expandable such that the general design could be used on different master/slave targets. Attention is also given to cost effective solutions such that development and possible market production can be considered. / Graduation date: 1999

With the success of the CounterDataFlow Pipeline microarchitecture developed by Oregon State University, there is increasing demand for a highly flexible high-level simulator modeling tool to support the further expansions and studies of the Counterflow pipeline processors family. This work examines the implementation of a Java-based execution-driven simulator modeling tool, bBlocks, which gains flexibility by identifying the independent parts in a micro system and partitioning them into reusable blocks. Two simulators have been constructed to demonstrate the possibility of bBlocks. / Graduation date: 2001

The purpose of this mixed-methods research study was to investigate the use of a closed social network, utilizing Ning, in an online educational environment. The research question driving this study was, does a student-centered online tool, such as Ning, foster knowledge construction through discussion boards more than a class-focused online tool, such as a traditional CMS? The participants were students enrolled in one of two online graduate education courses, one in a traditional Course Management System (CMS), and another class that utilized Ning for their discussions. Discussion Board postings from the Ning group were categorized based on the Interaction Analysis Model (IAM) developed by Gunawardena, C. N., Lowe, C., & Anderson, T. (1997), to assess knowledge construction. Survey instruments and interviews were conducted to provide additional insight into the use of a social network in an educational context.
