  • Perceptions of the average driver's speed compared to perceived driver safety and driving skill.

    Walton, D.; Bathurst, J. (1998)

    Working or discussion paper
    Open Polytechnic

    This study investigates the self-enhancement bias in driver attitudes, the finding that drivers rate themselves better than the average driver on safety and skill perceptions (Svenson, 1978, 1981; McCormick, Walkey & Green, 1986). A sample of 86 New Zealand drivers were asked their perceptions of their own and others' speeds in two conditions, 50 km/h and 100 km/h. The results established the self-enhancement bias for speed and safety, but not skill. Between 85% and 90% of drivers claimed to drive slower than the 'average driver.' A new methodological technique derived from Harr? and Gillett (1994) was used to investigate the direction of the self-enhancement bias. The results support Downward Comparison Theory (Wills, 1981) because drivers consider other drivers negatively, rather than exaggerating their self-perceptions.

  • Software development, CASE tools and 4GLs—A survey of New Zealand usage. Part 1: 750 New Zealand organisations

    MacDonell, Stephen (1993-11)

    Working or discussion paper
    University of Otago

    This paper reports the results of a recent national survey which considered the use of CASE tools and 4GLs in commercial software development. Responses from just over 750 organisations show a high degree of product penetration, along with extensive use of package solutions. Use of 3GLs in general, and of COBOL in particular, is still relatively widespread, however. In terms of systems analysis and design techniques under a CASE/4GL environment, screen and report definition is the most preferred technique, although both dataflow analysis and data modelling also feature strongly.

  • Finding medical information on the Internet: Who should do it and what should they know

    Parry, David (1999-06)

    Working or discussion paper
    University of Otago

    More and more medical information is appearing on the Internet, but it is not easy to get at the nuggets amongst all the spoil. Bruce McKenzie's editorial in the December 1997 edition of SIM Quarterly dealt very well with the problems of quality, but I would suggest that the problem of accessibility is as much of a challenge. As ever-greater quantities of high quality medical information are published electronically, the need to be able to find it becomes imperative. There are a number of tools to find what you want on the Internet---search engines, agents, indexing and classification schemes and hyperlinks, but their use requires care, skill and experience.

  • Establishing relationships between specification size and software process effort in CASE environments

    MacDonell, Stephen (1995-07)

    Working or discussion paper
    University of Otago

    Advances in software process technology have rendered many existing methods of size assessment and effort estimation inapplicable. The use of automation in the software process, however, provides an opportunity for the development of more appropriate software size-based effort estimation models. A specification-based size assessment method has therefore been developed and tested in relation to process effort on a preliminary set of systems. The results of the analysis confirm the assertion that, within the automated environment class, specification size indicators (that may be automatically and objectively derived) are strongly related to process effort requirements.

  • Exploiting the advantages of object-oriented programming in the implementation of a database design environment

    Stanger, Nigel; Pascoe, Richard (1997-06)

    Working or discussion paper
    University of Otago

    In this paper, we describe the implementation of a database design environment (Swift) that incorporates several novel features: Swift’s data modelling approach is derived from viewpoint-oriented methods; Swift is implemented in Java, which allows us to easily construct a client/server based environment; the repository is implemented using PostgreSQL, which allows us to store the actual application code in the database; and the combination of Java and PostgreSQL reduces the impedance mismatch between the application and the repository.

  • Neuro-fuzzy methods for environmental modelling

    Purvis, Martin; Kasabov, Nikola; Benwell, George L; Zhou, Qing Qing; Zhang, Feng (1998-12)

    Working or discussion paper
    University of Otago

    This paper describes combined approaches of data preparation, neural network analysis, and fuzzy inferencing techniques (which we collectively call neuro-fuzzy engineering) to the problem of environmental modelling. The overall neuro-fuzzy architecture is presented, and specific issues associated with environmental modelling are discussed. A case study that shows how these techniques can be combined is presented for illustration. We also describe our current software implementation that incorporates neuro-fuzzy analytical tools into commercially available geographical information system software.

  • Information portrayal for decision support in dynamic intentional process environments

    Wong, B L William; Sallis, Philip; O’Hare, David (1995-07)

    Working or discussion paper
    University of Otago

    This paper reports on preliminary findings of a cognitive task analysis conducted at an ambulance despatch control center. The intense and dynamic nature of the decision making environment is first described, and the decision process modelled in an attempt to identify decision strategies used by the Communications Officers. Some information portrayal requirements stemming from one of the decision processes are then discussed, and these requirements are then translated into a proposed display solution.

  • Modifications to Smith’s method for deriving normalised relations from a functional dependency diagram

    Stanger, Nigel (1999-12)

    Working or discussion paper
    University of Otago

    Smith’s method is a formal technique for deriving a set of normalised relations from a functional dependency diagram (FDD). Smith’s original rules for deriving these relations are incomplete, as they do not fully address the issue of determining the foreign key links between relations. In addition, one of the rules for deriving foreign keys can produce incorrect results, while the other rule is difficult to automate. In this paper are described solutions these issues.
