DHNet: a model for international research collaboration.

Internet technology has changed the way information is accessed, shared, and stored. This technology has supported the growth of scientific networks based on the need for improved communications and a team approach to problem solving. Scientists throughout the world are now able to come together in "virtual laboratories" or "collaboratories" to conduct research, analyze data, and discuss findings in a more timely and cost-efficient manner. The DHNet is based on a collaboratory model. It is a Web-based Internet resource designed to encourage research collaboration among dental hygiene professionals without regard to geographic location. The DHNet creates an electronic infrastructure that facilitates the linking, relating, and clustering of concepts that are critical to advancing a body of knowledge. It also creates a new standard for placing information on the Internet, which currently lacks conventions and structures for knowledge management. Designed to be maintained by its users with minimal staff support, the DHNet provides a mechanism for electronic publication of clinical observations, research, research in progress, and other document/media types. DHChat, the discussion forum component, provides an electronic communications tool for discussing topics of interest, research questions, and ways in which researchers would like to work together. Depending on the nature of the investigation, multi-site studies can be conducted or researchers can be responsible for different aspects of the same study. Video conferencing from desktop computers now permits synchronous discussion, enabling participants to see each other and work on the same document. The purposes of this article are to discuss the design of the DHNet as a model for supporting international research collaboration, and to discuss issues related to the use of electronic technology.
