The interaction between training and change in South African organisations

Abstract: This article outlines the results of a study which investigates the interaction between training and change in South African organisations. A literature study provides a theoretical foundation which explains the nature of the interaction between training an change in the organisation. An empirical survey was conducted, using a self-administered questionnaire which was sent to 365 training practitioners to test six null-hypotheses. To prove the stated hypotheses, specific statistical methods, such as analysis of variance and correlation coefficients, are used. The results showed highly significant relationships between training and organisational change variables (one of the null-hypotheses was rejected). The results indicated that management should use training to facilitate change in the organisation. This, however, requires a shift in emphasis regarding the traditional role of training in the organisation. Training should be placed at the centre of human resources practices and the strategic plans of the organisation.

Elements of humour in selected works of S.M. Burns-Ncamashe

Abstract: S.M. Burns-Ncamashe's literary works (both poetry and prose) display an extensive employment of humour. This is not surprising as the author himself seems to have been a humorist by nature. The idea of his having been a humorist and the manifestation of this element in his writings are confirmed by Pahl in the introductory part of Burns-Ncamashe (1979), where he points out that Burns-Ncamashe's writings are full of humour and that, wherever Burns-Ncamashe would be, people would not stop laughing because of his humorous nature. It is for the manifestation of this aspect in the literary works of Burns-Ncamashe that the discussion in this paper is undertaken. In this discussion attention will be given to the definition of the concept of humour, its types as well as its significance.

Differential scanning calorimetric study of the interaction of 2,2′‐dibenzothiazole, sulfur, zinc oxide, and stearic acid in the presence of polyisoprene

Abstract: The interactions between mixtures of 2,2'-dibenzothiazole (MBTS), sulfur, ZnO, and stearic acid were studied by DSC in the presence of polyisoprene (IR). In the absence of ZnO, the onset of vulcanization was at a lower temperature than in its presnece, and the crosslink densities were relatively low. ZnO as well as stearic acid did not influence the consumption of MBTS, but the amount of MBT in the sample after vulcanization increased in the presence of ZnO and still more when ZnO and stearic acid were present—the same applied for the crosslink densities. In view of these results, interaction mechanisms are proposed for the different systems.

Phosphonic systems. part 13. alkylation of diethyl cyclohexenylphosphonates

Abstract: Alkylation of cyclohexenylphosphonates was found to proceed under very mild conditions. The reaction usually occurred in a regioselective fashion with α-addition predominating. Steric effects were significant and had a bearing on the regioselectivity of the reaction.

On rings generating atoms of lattices of special and supernilpotent radicals

Abstract: This note is to indicate a nonsemiprime ring R such that the smallest supernilpotent (respectively special) radical containing the ring R is an atom of the lattice of all supernilpotent (respectively special) radicals. This gives a positive answer to Puczylowski's and Roszkowska's question.
