  • Description: This research report sets out to examine the concept of People’s Education in South Africa from December 1985, when the call for People’s Education was first made, to September 19877“It is the result of a preliminary six month research project which set out to lay the basis for a long term study of international perspectives on People’s Education. The researcher experienced the difficulties associated with doing contemporary research in a charged political environment. Several of the potential interviewees were either in detention or ‘on the run’ because of their commitment to People’s Education. The contemporary nature of the research focus also meant that the sources of relevant printed materials were limited and dispersed. The study demonstrates that People’s Education is concerned with more than responding to ‘the education crisis'. In addition, it is attempting to address the problem of a future education system in a post-apartheid society. As adult educators we are excited by the challenges that People’s Education offers. It is one of the first times in South Africa that ‘lifelong education ’ is on the agenda where education in the school is seen as only one aspect of necessary education provision. Adult Education at the workplace, in voluntary associations, in political movements, in the home, is seen as integral to the educational process both in the period of social transformation and in a future, post-apartheid society. This study has confirmed that People’s Education cannot be ignored. People’s Education has achieved what many previous investigations into education have not achieved; it has involved a wide range of grassroots people in the debates around the future of South African education. It is an ongoing process. As Ken Hartshorne is quoted as saying : "Both the debate on and the process leading to post-apartheid education are well underway; they are loaded with complexities, uncertainties and risks, because they are taking place in an unstable and unresolved vortex which changes from day to day, from place to place." I would like to acknowledge the assistance of colleagues who played an important role in the process of the study : Professor Owen van den Berg who was very helpful in the setting up of the project, and Mr Brian O’Connell who assisted with the conceptualisation and ongoing discussion of the project. In addition, his critical reading of the draft of this report provided many invaluable suggestions. Thanks are also due to our colleagues at UWC and elsewhere who took time to read the draft paper and offered constructive criticisms.

  • Description: This study set out to analyse the concept of the ʾcoloured communityʾ and to describe the linguistic phenomena associated with it. It was found that the community was characterized by division and an overt rejection of 'coloured' identity. A satisfactory definition of the community could only be arrived at by exploring social psychological and anthropological concepts, particularly that of the social network, and a covert identification was postulated. This in turn was used to explain the linguistic phenomena which were found to be associated with the community. The latter included a vernacular dialect consisting of non-standard Afrikaans blended with English, as well as a stratification of particular items in the English spoken by community members . This stratification was analysed in terms of the social distribution of the items, enabling comparisons to be made with the English spoken by ʾwhitesʾ. A fieldwork study was embarked on with the intention of discovering the nature of the perceptions of, and attitudes towards, the idiolects of certain speakers. These idiolects were considered to be typical and representative of the forms of English normally encountered in the Cape Peninsula, and were described in terms of the co-occurrences of linguistic items which they contained. Tape recordings of the speech of this group of speakers were presented in a series of controlled experiments to subjects from various class and community backgrounds who were required to respond by completing questionnaires. It was found that those lects which contained items and co-occurrences of items peculiar to 'coloured' speakers were associated with lower status than those containing items and co-occurrences of items peculiar to 'white' speakers. Attitudes towards speakers were found to be more complex and depended upon the styles and paralanguage behaviours of the speakers, as well as accent, and also the psychological dispositions of the subjects who participated

  • Description: The eight Lower Group chromitite layers of the Ruighoek Pyroxenite in the area west of the Pilanesberg (LGl - LG7), on the farm Zandspruit 168 JP, were sampled in borehole cores drilled through the succession. The stratigraphic succession faIls within Cameron's (980) units B to E of the Critical Zone. The lowermost layer of the Lower Group, the LG 1 chromitite, is located some 440 metres below the MG 2 (Middle Group) chromitite layer, above which the first appearance of cumulus plagioclase in the Complex is seen. By convention, this horizon is designated the top of the Ruighoek Pyroxenite in the Western Bushveld Complex. Homogeneous units of chromite-bearing orthopyroxenite (bronzitite), exhibiting inconspicuous layering defined in terms of variations in orthopyroxene grain-size host all but one of the Lower Group layers; the LG 4 chromitite layer is exposed within an olivine-rich subunit 23 metres in thickness (C₃ subunit). The cumulative thickness of chromitite is 2,92 metres or 0,8 per cent of the studied section, which is 381 metres in thickness. Minimum and maximum thicknesses of the LGl - LG7 layers exposed in drill core are 17 and 81 centimetres, respectively, with minor chromitite layers ranging between 2 and 5 centimetres in thickness. Weighted mean Cr₂0₃ contents of units B to E vary between 1,17 and 3,22 per cent, with the latter estimate representative of the D₂ subunit which hosts the LG 6 chromitite layer. The LG 6 is correlated with the Steelpoort layer of the Eastern Bushveld Complex, and varies between 76 and 81 centimetres in thickness under a large portion of the farm Zandspruit. An undisturbed succession striking N15°E and dipping 12 - 15°E is depicted within the studied area, which is bounded on the eastern side by the north-striking Frank fault. Major folding of the layered succession is evident to the north of the area, where the layering adjacent to the trace of the fault dips 35° to the southwest. Particular attention is paid in the present study to (a) the nature of chromitite layers and their host rocks, (b) the contrast between the mineral chemistry of weakly disseminated chromite and grains within massive ore layers, (c) concentrations of Cr, V, Ni, Co, Sc and Ti in orthopyroxene in relation to stratigraphic height, and levels of Sr, Ba and Zr associated with hypothetically pure, intercumulus plagioclase feldspar, and (d) possible mechanisms which induce crystallization of chromitite layers containing 50 per cent Cr₂0₃ from magma with a Cr content of less than 1 000 ppm. Electron microprobe studies of chromite in relation to mineralogical and textural environment clearly reveal that (a) the proportions of Cr and Al cations are linked to paragenesis: higher Al/Cr ratios characterize olivine-bearing domains, whereas grains intergrown with plagioclase feldspar exhibit low AI/Cr ratios, and (b) Al contents rise with a decline in Mg/(Mg + Fe²⁺) from high values to a value of 0,450, then decrease with a further decline in Mg/(Mg + Fe²⁺). The paragenetically later trend is emphasized in a large population of chromite grains which escaped early encapsulation in orthopyroxene crystals and continued to grow in the environment of intercumulus plagioclase. Within-and between-sample compositional variation of grains in silicate-rich domains is modelled in terms of in situ growth increments, diffusive homogenization of zonal structures, and residence time within interstitial melt. Fractionation trends, as measured by Mg/(Mg + Fe²⁺) ratios in whole-rock and/or microprobe studies of orthopyroxene, are reversed in relation to stratigraphic height towards the top of the B unit and in the overlying C unit. These data are supported, for example, by lower vanadium contents and higher Ni/Sc ratios in hypothetically pure orthopyroxene. Small olivine crystals in chromite-rich domains are enriched in Ni relative to coarse-grained olivine in adjacent dunite: a feature attributed to early isolation of primocrysts from magma in the former case, and in situ equilibration between olivine crystals and Ni-depleted residual melt in the latter case . Similarly, rising Ni contents and Mg/(Mg + Fe²⁺) ratios of orthopyroxene with increasing stratigraphic height in the footwall of the LG 6 chromitite layer, linked to a progressive decline in orthopyroxene grain-size, are effects which may arise out of early separation of interstitial melt from orthopyroxene cumulates. A model is thus proposed which (a) links the thickness of chromitite layers to the vertical separation between successive layers or the thickness of fine-grained orthopyroxenite in the footwall, (b) ascribes copious nucleation of chromite to liquid mixing of this footwall derived, Cr - depleted contaminant with influxes of hot, primitive magma, and (c) tenders the notion that the present modal proportion of mesostasis in the footwall of a chromitite layer serves as a reciprocal measure of the volume of fractionated exudate

  • Description: Phenylpropanolamine (PPA), a synthetic sympathomimetic amine structurally related to ephedrine has been widely used over t he past 40 years as a nasal decongestant and appetite suppressant. It has been the focus of much controversy concerning the efficacy of the drug in its use as an anorectic agent, and due to the side effects caused by the higher doses of PPA required for appetite suppression. Although extensively used, there is little information concerning the determination of PPA in biological fluids and on the pharmacokinetics of this drug. An adaptation of a published high-performance liquid chromatographic (HPLC) assay for PPA in serum and urine using U.V. detection at 210 nm is presented. PPA was separated in the reversed phase mode. The method has a limit of sensitivity of 5.0 ng/mL and 10.0 ng/mL in serum and urine respectively. Serum concentration data following a single 25 mg dose of phenylpropanolamine in human volunteers demonstrate the application of the analytical method for bioavailability and pharmacokinetic studies. After the administration of 25 mg, 50 mg or 100 mg PPA.HCl solutions to 5 human volunteers, a dose proportionality study demonstrated that PPA appears to exhibit linear kinetics. Linear one body compartment kinetics were assumed and the wagner-Nelson method used to transform in vivo serum data to absorption plots. The serum data were fitted to a model using nonlinear regression techniques to characterize the pharmacokinetic processes of PPA. The absorption of phenylpropanolamine appears to be discontinuous and the drug seems to favour a two body compartment model. The pharmacokinetic parameters obtained from a steady state study using multiple dosing of PPA.HCl solutions compared with those found from previous studies after the administration of sustained-release formulations. A plasma protein binding study using equilibrium dialysis demonstrated that PPA is not highly protein bound in the blood.

  • Description: Experimental vaccines have been made by covalently bonding virus particles into polymerized rabbit serum albumin beads. Using Nodamura virus as a model antigen, these model vaccines induced specific humoral antibody production, comparable with that achieved using Freund's adjuvants. Virus specific antibodies were also induced when Nodamura virus was covalently attached to the bead surface using different crosslinkers. However, when poliovirus type 2 (Sabin strain) was polymerized into beads, the levels of neutralizing antibodies were insignificant compared with control aqueous vaccines. The synthetic immunostimulator, muramyl dipeptide, was included with bead vaccines in an attempt to potentiate the immune response. Immunostimulation is achieved by a slow release of antigen coinciding with the gradual breakdown of bead structure.
