    Research accentuates that end-users‘ noncompliance with information security policy (ISP) is a key concern for government just as it is for the private sector. Although awareness and training programmes are important factors ...
  • Viktor, HL; Rennhackkamp, MH (South African Institute of Computer Scientists and Information Technologists, 1991)
    A recovery technique, to facilitate the recovery from system failures should ensure a consistent database state at all times. The UNIX write system call uses a delayed-write policy. Data blocks are kept in a buffer cache ...
  • Sutcliffe, Geoff (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    In general graph theorists have a limited knowledge of computers and computing, and are unaware of the possible variations of representation available, and in what circumstances which representation would be better. To ...
  • Tidwell, LD; Schach, SR (South African Institute of Computer Scientists and Information Technologists, 1991)
    It is becoming increasingly difficult for researchers with little or no formal computer science background to make effective use of supercomputers and other vector machines in their own fields of research. Automatic ...
  • Short, R. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    Formalisms comprise the essential bricks and mortar that we need in order to construct information systems. Not surprisingly therefore the invention and refinement of formalisms has formed and continues to form a ...
  • Machanick, Philip (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    After a brief look at how the notion of the stored program is applied by programmers in the area of Artificial Intelligence (Al), we shall look at a specific Al tool: a production svstem. The discussion is at a ...
  • Turton, Trevor (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    This paper describes computer design which 'would achieve a high instruction throughput rate on a relatively modest amount of hardware. It is based on multiprogramming the CPU at a sub-instruction level. The design will ...
  • Richfield, J.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Structured program design is urged as a rewarding vehicle for the introduction of computer concepts to age groups ranging from mid primary school to senior management. Progressively expanded subsets of the material form ...
  • Mueller, C.S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Why concurrency in itself should be seen as a method of programming, is discussed. Current approaches to concurrent programming are evaluated in terms of e~e qt programming. The properties required to decompose the ...
  • Kaplan, S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The notion of and mot1vat1on for intelligent editor systems 1s introduced, spec1f1cally a language independent intelligent editor called "PASTOR" We also introduce and discuss the metalanguage used in the editor for grammar ...

    The South African Data Centre for Oceanography (SADCO) has implemented a multi d1sc1plinary oceanographic database using OMS 170, a relational database management system Using a high level query language sc1ent1sts from ...
  • Jablonski, J.; Dijkman, J.H. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The design of a high speed graphics workstation 1s presented A spec1f1caly designed Graphics System Interface com bines standard computer peripherals to produce a soph1st1cated man machine workstation A review 1s given ...
  • Ahmed Yasin Mohammed (2017-07)
    Background: Access to safe water and sanitation are universal need and basic human right, but the provision of quality water and improved sanitation remains a challenge in many African countries including Ethiopia. Objectives: ...
  • Roets, P. P. (Computer Society of South Africa (on behalf of SAICSIT), 1982)
    An evaluation is made of the improvement of language interpreters by coding recurring sequences of instructions in micro-code. The results of an experiment with PASCAL indicate that the increase in speed expected may not ...
  • Nagitta, O.P.; Mkansi, M (International Business Conference (IBC), 2015)
    The coordination frameworks measure coordination as an index of six dimensions of top management commitment: mutuality, relationships and decision responsiveness. These six dimensions present mainly micro internal factors ...
  • Mkansi, M; Eresia-Eke, C; Emmanuel-Ebikake, O (Cogent OA, 2018)
    The purpose of the study is to identify logistic elements germane to egrocery businesses, and to reveal the challenges collateral with each logistic element. Further, it strives to create a better understanding of specific ...
  • Mkansi, M; Acheampong, .E.A. (Academic Publishing International Ltd., 2012)
    Research philosophy classifications such as ontology, epistemology, and anxiology and their conflicting applications to the ‘quantitative-qualitative’ debates, are a major source of dilemma to research students in establishing ...
  • Smith, DC; Hansen, AL; Oosthuizen, NC (South African Institute of Computer Scientists and Information Technologists, 1991)
    Staff Shortages in the Information Systems industry are a continuing problem. Job turnover of IS staff contributes to this shortage and is particularly high in South Africa. This high turnover is often attributed to ...
  • MacGregor, K.J. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    The discipline of Computer Science has been established for almost twenty years. In SOUTH AFRICA, Computer Science Departments have been in existence for fifteen years, and producing graduates for twelve, however, the ...
  • Hirsch, Michael; Schach, Stephen R.; Van Biljon, Willem R. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    Two approaches to high-level debugging systems for Pascal are compared, namely the use of a debugging precompiler as against a debugging interpreter. A description is given of a high-level Pascal debugging interpreter ...
