- Description: The Etendeka Formation volcanics consist of a bimodal association of basalts and quartz latites. Forty three new whole rock oxygen isotope analyses are reported for all the major magma types. All the rocks except a minor suite of dolerites have higher δ18O values than normal mantle. The basic rocks (average of 29=8.8‰) have significantly different δ18O to the acid rocks (average of 10=14.4‰). These data are apparently consistent with previously published petrogenetic models, which propose that the basalts were affected by crustal contamination and that the quartz latites are crustally derived.

- Description: The paper discusses the application of the Ward and Mellor structured development techniques for real-time systems to the field of simulation. The tools and heuristics used by Ward and Mellor are extended to provide a useful approach to the design of real-time simulations. This is illustrated by the example of a real-time simulation of a manufacturing plant and process control system.

- Description: The first six months of 1989 has proved to be as busy as predicted, and the demand for mediation and arbitration services has increased steadily during this period. Year on year, whereas there were some 120 mediations and 75 arbitrations during the first six months of 1988, there were 195 mediations and 117 arbitrations during the first six months of 1989. This increase in demand may be attributed to a number of factors. In the first place, with the ever increasing unionisation of workers in South Africa a wider range of parties are resorting to third party intervention to resolve disputes. Secondly, labour and management who have had experience of mediation and arbitration, have continued to use third party neutrals to assist them in the process of dispute resolution. And thirdly, given the current political climate and the attitude of the major trade union federations to the recent amendments to the Labour Relations Act, it is apparent that parties are turning with greater frequency to independent third party neutrals to assist them resolve conflict. There are, for example, an increasing number of recognition agreements which require that conflicts of right be adjudicated through private arbitration under the auspices of IMSSA. Some German multinationals have, in accordance with the IG Metaal Code of Conduct for German investors in South Africa, agreed to refer disputes of right to private arbitration. IMSSA has for some time now been cited in the disputes procedures of many recognition agreements as the source of mediators.
