  • Some current practices in evaluating IT benefits in South African organisations 
    Sutherland, F (South African Computer Society (SAICSIT), 1994)
    IT has a dynamic impact on organisations and little research has been done especially on the extent to which senior executives take the different system types into account when they appraise an IT investment. The aim of ...
  • Specialization by exclusion 
    Theron, H; Cloete, I (South African Computer Society (SAICSIT), 1994)
    This paper presents a theoretical analysis of the search schemes employed by AQ, CN2 and the recently introduced BEXA algorithm. These covering algorithms induce disjunctive concept descriptions, and employ a general-to-specific ...
  • The innovative management of information in the mid-1990s 
    Remenyi, D (South African Computer Society (SAICSIT), 1994)
    This paper reviews recent literature on the subject of the operational and financial difficulties facing business and manage­ment in the mid 1990's. It identifies how, due to generally poor results, business is under more ...
  • A linear time algorithm for the longest (s-t)-path problem restricted to partial k-trees 
    Mata-Montero, M; Ellis, JA (South African Computer Society (SAICSIT), 1994)
    The Longest (s-t)-path Problem, a known NP-complete set, is shown to admit a linear time solution when the instances of the problem are restricted to partial k-trees. This class of graphs is defined and some of the properties ...
  • Organizational computing technologies for supporting organizational activities 
    Lochovsky, FH (South African Computer Society (SAICSIT), 1994)
    Technologies for supporting organizational activities are becoming increasingly important as a means for organizations to achieve their business goals. Such technologies allow organizations to model, execute, and control ...
  • On using the situation calculus dynamically rather than temporally 
    Labuschagne, W.A.; Miller, MG (South African Computer Society (SAICSIT), 1994)
    Yet another axiomatisation of the Yale shooting scenario is provided. The point illustrated by the axiomatisation is that, when using the situation calculus to represent knowledge about a dynamic system in which actions ...
  • Teaching Pascal using multimedia 
    Jordaan, DB; Gilliland, S (South African Computer Society (SAICSIT), 1994)
    Research has shown that traditional teaching methods such as lecturing are not always as effective as the teacher or lecturer might like them to be. Frederick [3, p45] stated: 'Nearly all learning theorists.faculty development ...
