In rural Australia in the early twenty-first century, telecommunications reform has seen the rise of local telecommunications as a new way to wire the country, delivering new technologies and meeting community needs and aspirations. 1his paper discusses the prospects for local telecommunications in light of a research project on online rural communities commissioned by the Telstra Consumer Consultative Council. Based on interviews conducted in three small towns in rural eastern Australia, the paper examines the role of community networking as a new force in telecommunications service delivery, posing questions for local and regional communications policy development.

Socialist Republic of Vietnam's reform process in the telecommunications sector - obligations imposed on Vietnam by the Bilateral Trade Agreement (BTA) - the regulatory framework required by the General Agreement on Trade in Services (GATS) and the associated, telecommunications-specific WTO agreements - institutional and political problems that may hinder full implementation of these international obligations.

This article considers questions of technological change, innovation, and communication from a disability perspective. Using a critical social perspective on disability, we offer an Australian case study to analyse disability in national telecommunications policy. In doing so, we critique the systemic lack of incorporation of disability in national visions, policies, and programmes. Accordingly, we argue for a cohesive, and genuine commitment to incorporating disability considerations in all areas of information and communication technology policy and scholarship.

The effects of process variables on the quality of high-pressure die cast components was determined with the aid of in-cavity pressure sensors. In particular, the effects of set intensification pressure, delay time, and casting velocity have been investigated. The in-cavity pressure sensor has been used to determine how conditions within the die-cavity are related to the process parameters regulated by the die casting machine, and in turn the effect of variations in these parameters on the integrity of the final part. Porosity was found to decrease with increasing intensification pressure and increase with increasing casting velocity. The delay time before the application of the intensification pressure was not observed to have a significant effect on porosity levels. (c) 2006 Elsevier B.V. All rights reserved.
