S. V.  aAssessing the potential of microcomputer-based expert systems in the process of agricultural technology transfer in Brazil  aEstados Unidos da América: The George Washington Universityc1986  a267p.  aTese Doutorado.  aThis study focused on technology transfer problems in the agricultural sector. The research hypotheses were to assess the potential use microcomputer-based expert systems as (1) mechanisms for transferring technical information between agricultural research and rural extension programs ,(2) training aids for extensionists (county agents) programs, and (3) tools for gathering relevant information from farmers and extensionists for research and extension management. The study also addressed the integrative role that expert systems technology plays in the overall process of technology transfer in the agricultural area, as well as the self-improving feature the technology introduces to the Total System (research + extension+ farmers) of agricultural technology development. A prototype expert system was developed for diagnosing and recommending treatment for selected potato diseases. In an experiment carried out in an extension organization in Brazil, 56 extendionists used the prototype and filled out a questionnaire designed to test the research hypotheses. Forty-five agricultura researchers and university professors in the agricultura field were also interviewed.
