- Description: Organised labour continues to play a prominent role in shaping employment relations in South Africa. The individual worker is powerless and in a weaker bargaining position against his employer. The advent of democracy was accompanied by numerous interventions to level the historically uneven bargaining field. The trade union movement has made and consolidated significant gains since the advent of democracy. It however faces a plethora of new challenges, such as the negative forces of globalisation, declining membership (often associated with high levels of unemployment and the changing nature of work from standard to atypical employment), the resurfacing of adversarialism in the bargaining process, and numerous shortcomings inherent in forums established to facilitate corporatism. Business is intensifying its calls for investor-friendly policies, which effectively mean a relaxation of labour policies. The trade union movement faces an enormous task of rebuilding confidence and credibility among its members and at the same time showing some commitment to other social actors, government and business, that it is committed to contribute to economic growth and employment creation. The central focus of this thesis will be to highlight the gains made by the trade union movement, the numerous challenges threatening their existence, and how they have attempted to redefine their role in the face of these challenges. It will attempt to offer advice on how trade unions can continue to play a prominent role in shaping relations of work in South Africa. The study begins with a historical overview of trade unionism in South Africa. It then attempts to establish how trade unions have made use of the institution of collective bargaining, the importance of organisational rights to the trade union movement, the effectiveness of industrial action, and the emerging challenges threatening the vibrancy of trade unions. The overall aim is to assess whether the trade union movement is still a force to be reckoned with and its future role in influencing employment relations in South Africa.

The effect of pineapple cultivation on factors influencing soil erodibility in the Eastern Cape, South Africa

- Description: The study examines the effect of ridged pineapple cultivation on factors influencing the soil erodibility of Glenrosa and Oakleaf soil forms in the Bathurst district of South Africa. A number of physical and chemical variables influencing soil erodibility are investigated, namely soil moisture, bulk density, porosity, infiltration rate, aggregate stability, shear strength, soil texture, soil structure, penetrability, organic carbon, pH and cation exchange capacity. These soil characteristics are examined in undisturbed soils under natural vegetation and compared to those on adjacent traffic areas, pineapple ridges and pineapple furrows. The results of the analyses between the four sample sites indicate that ridged cultivation of pineapples has a negative effect on factors influencing soil erodibility on the areas studied. The results of the analysis within each of the sample sites do not illustrate any clear relationships and thus depict the complexity and multiplicity of the soil erodibility phenomenon. A further study, augmenting the soil erodibility data with actual soil loss data, is recommended

Investigation of the formation of complexes between selected organic compounds and the chlorides and sulphates of chromium

- Description: Some properties of soluble chromium complexions containing coordinated aliphatic acids have been studied. The work falls naturally into two sections. In the first, the coordination of a series of ⊄, β and⊁amino acids by chromium chloride has been studied by physical methods. The tanning action of chromium chloride in the presence of these amino acids has also been studied. The absorption spectra of the complexes were similar to those reported previously for trivalent chromium solutions, having two pronounced maxima in the visible region. From the variations in these absorption maxima, it is suggested that the absorption maximum in the 580 m u region is influenced by coordination of the chromium with the ligand, while the maximum in the 420 m u region is also affected by the olation of the basic chromium salts. The spectrophotometric evidence indicates that raising the pH or the concentration of the ligand in the solution increases the amount of coordination, and further, that the tendency for coordination increases as the hydrocarbon chain separating the carboxyl and amino groups becomes longer. This suggests that tho stability of the complex is not dependent on chelate ring formation, but is influenced by the pK₁ value of the carboxyl group of the . ligand. Potentiometric titrations support the hypothesis that only the carboxyl group is coordinated, to an extent depending on its pK₁ value, since the curves have shown that the amino group is still free to titrate. Paper electrophoresis has shown that all the complexes prepared were cationic, indicating that the amino acids were coordinated as dipolar ions. The tanning action of the masked chromium solutions has confirmed the deductions made from the physical measurements. Increasing the amount of amino acid added to the solution lowered the chromium fixation and the hydrothermal stability of the leather, and further, that for solutions at the same pH containing the same amount of masking agent, tanning action was least for the ⊁ amino acid and greatest for the ⊄ amino acids. Comparison of the present data with the corresponding results obtained with chrome alum solutions showed that coordination of the amino acids was greater in the case of the chromium chloride solutions. The second section of the experimental work was an investigation of the coordination of substituted acetic and propionic acids by chromium chloride and chromium sulphate. Spectrophotometric and potentiometric methods were applied and the various solutions were also used in miniature tanning experiments. Certain difficulties were encountered in the preparation of some of the complexes, and it was not possible to carry the work to a point where conclusive results could be obtained. Nevertheless, the work reported suggests that chelate ring formation occurs in the coordination of hydroxy-carboxylic acids, resulting in exceptionally high stability of the complex. In the case of the other ligands, containing amino, chloro and bromo groups, as well as with acetic and propionic acids, the results suggest that coordination involves the carboxyl group only, and that the pY value of this group is an important factor determining the stability of the complexes.
