Microcomputers in Applied Settings: The Example of Urban Planning

Two models of the diffusion of computer use and the use of more sophisticated social science methodology in applied settings are posited: Top-down diffusion involves the spread of sophisticated techniques from larger to smaller agencies, while grass-roots diffusion involves the gradual upgrading of methods used in a wider range of settings. Possible examples of the role of microcomputers in fostering both types of diffusion in urban planning are described. The two models imply different kinds of computer training for professionals.
