  • The Relative Merits of Two Organisational Behaviour Models for Structuring a Management Information System 
    Pirow, Peter (Computer Society of South Africa (on behalf of SAICSIT), 1982)
    The basic 'model' usually applied to the structure of MIS is that of Anthony. This paper investigates the use of the Paterson model as an alternative. This is approached from the theoretical standpoint, and reference is ...
  • Research computeracy 
    Pirow, Peter Cluver (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    This paper describes the concept of computeracy as it applies to research workers and argues that research will be improved if the level of computeracy can be raised.
  • Research directions in information systems 
    Mende, J. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    The success of a research project depends upon the inputs and outputs selected by the researcher, a poor choice entailing useless results or wasted efforts.To avoid this one might consider the following alternatives: t. ...
  • Restructuring of the Conceptual Schema to produce DBMS Schemata 
    Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
