This week, THESIS, The THES internet service, launches the online version of Higher Channels, our TVand radio listings service (in The THES this week on page 24). The online version lists more programmes and will be expanded with web links, reading lists and other extras. And from Tuesday, join in our new THES/Nexus debate on the knottiest problem in business:how would you run a genetically modified crop company? Also job advertisements and a summary of The THES, with a complete, searchable archive of the newspaper back to October 1994 for subscribers. Details from 01858 438805 www.thesis.co.uk
