This is a definitive introductory text to modern sociolinguistics that looks at the study of language and society through the concept of identity. It uses these sociolinguistic constructs of identity to tie together current concepts and methods in the field, offering a full overview of the discipline, both past and present. Deckert and Vickers adopt an interdisciplinary approach, introducing work from a variety of fields that examine sociolinguistic data, from linguistics to anthropology, sociology, psychology and education. The book moves from looking at language varieties and globalization to a close examination of language in social interaction, covering the concepts of ideology and power. Throughout, the authors offer keen insight into all of the topics, issues and methods that students of language and society will need to understand. The chapters contain a range of pedagogical features, including key terms, study questions, chapter summaries and further reading. This is an essential new text for all those studying contemporary sociolinguistics, suitable for undergraduates and postgraduates alike.

Proceedings of the symposium, which explored how sustainable development applies to specific planning and policy decisions at the provincial and municipal levels, particularly in British Columbia. The symposium provided a forum for discussion among politicians, representatives from public interest groups, bureaucrats, and corporate executives. This document includes the keynote address by Stephen Lewis; workshop reports on provincial strategies, economic opportunities, planning sustainable communities, agriculture, forestry, fisheries and water, and non-renewables; and concludes with the symposium statement. A list of participants and their statements is also included.

This paper will briefly outline major activities in Department of Energy (DOE) Laboratories focused on mobileplatforms, both Unmanned Ground Vehicles (UGV's) as well as Unmanned Air Vehicles (UAV's). The activities willbe discussed in the context of the science and technology construct used by the DOE Technology Roadmap for Roboticsand Intelligent Machines (RIM)1 published in 1998; namely, Perception, Reasoning, Action, and Integration. Theactivities to be discussed span from research and development to deployment in field operations. The activities supportcustomers in other agencies. The discussion of "perception" will include hyperspectral sensors, complex patternsdiscrimination, multisensor fusion and advances in LADAR technologies, including real-world perception. "Reasoning"activities to be covered include cooperative controls, distributed systems, ad-hoc networks, platform-centric intelligence, and adaptable communications. The paper will discuss "action" activities such as advanced mobility and various air andground platforms. In the RIM construct, "integration" includes the Human-Machine Integration. Accordingly the paperwill discuss adjustable autonomy and the collaboration of operator(s) with distributed UGV's and UAV's. Integrationalso refers to the applications of these technologies into systems to perform operations such as perimeter surveillance, large-area monitoring and reconnaissance. Unique facilities and test beds for advanced mobile systems will bedescribed. Given that this paper is an overview, rather than delve into specific detail in these activities, other moreexhaustive references and sources will be cited extensively.
