Abstract: A 1mm-long Spirostomum with symbiotic chlorellae has been found in the oxygen-depleted sediment of a shallow fen pond in the South of England (UK). The ciliate lives amongst sediment debris, where it builds a lorica that covers about half the length of the ciliate. It is common to find several of the green Spirostomum cells sharing the same patch of sediment particles. [Copyright &y& Elsevier]

Considerable interest is currently being shown in the use of information technology to assist in improving group process, particularly those associated with strategic planning. Three major approaches are developing to provide this support, and these are described in this article. In general, articles about Group DSS are overwhelmingly favourable to the approaches, although research findings suggest that some forms of Group DSS can have deleterious effects on the quality of meetings. These research findings are discussed.
