-Quality of systems that support online learning, quality support infrastructure, quality of technical access and support, materials distribution; issues in each of these areas are considered.

-Quality of teaching and learning experiences, including a range of institutional projects using online technologies and issues of quality provision as well as areas of current and needed research.

-Measuring quality - evaluation and assessment looks at recent research in working towards sustainable quality learning by considering quality evaluation as a collective process.

-Administration and policy to support quality education @ a distance including institutional approaches to assuring quality and identification of differing perspectives for consideration.

Humic substances are ubiquitous in the environment. These remarkable brown biomaterials are found in animals, plants, coals, sediments, soils and water. They are crucial components of the carbon cycle and other life processes. Humic Substances: Nature''s Most Versatile Materials contains a compilation of papers presented at the 2002 Humic Substances Seminar and will keep humic substances scientists up to date with the latest research.

This book considers several aspects of providing quality education at a distance: Quality of systems that support online learning, quality support infrastructure, quality of technical access and support, materials distribution; issues in each of these areas are considered. It contains the papers presented at the working conference of Working Group 3.6 (Distance Education) of the International Federation for Information Processing (IFIP Geelong, Australia, Feb. 2003).

Humic substances, the remarkable brown biomaterials in animals, coals, plants, sediments, soils and waters, are crucial components of the carbon cycle and other life processes. Thus greater knowledge and understanding of these versatile materials is of great importance to the productivity, health and safety of the world''s ecosystems, humans, land and water. Presenting the best and most recent research in this important area, this book focuses on the molecular and chemical aspects of humic substances, with sophisticated analytical, chemical and physical techniques providing vital information. Areas covered include spectroscopy, modelling, mobility, properties and analysis of humic substances. Humic Substances: Structures, Models and Functions will be welcomed by researchers and professionals in academia, industry and government agencies worldwide, particularly where the science of humic substances finds applications, such as environmental remediation and sustainable agriculture.
