Center node: "interpretation as a factor in understanding flawed spreadsheets"
  Abstract: The spreadsheet has been used by the business community for many years and yet still raises a number of significant concerns. As educators our concern is to try to develop the students skills in both the development of spreadsheets and in taking a critical view of their potential defects. In this paper we consider both the problems of mechanical production and the problems of translation of problem to spreadsheet representation.
