- Description: Lovedale was founded by the Glasgow Missionary Society as an eduational centre for Africans. Education was to be adapted to the lives of the Africans which would be a departure from the English classical tradition. This meant that emphasis was placed on vocational training and that academic education focussed on the study of English rather than the Classics. But the importance of mother-tongue education was also stressed. The missionaries placed emphasis on village education, whereby the African would be taught skills and crafts that would be useful to him in life. Education, they argued, should also aim at character-training and at spreading the Christian message. They also wanted to see co-operation between the Church and the State in the education of the African. Vocational education was designed to create African artisans who would be able to compete with Whites; but it also aimed at emphasizing the importance of industry in building up character. The Lovedale Press illustrates vocational training in progress, dealing with the difficulties that arose when African printers came into competition with Whites. But the missionaries also used the Press to propagate the Christian message and to promote African literature. An ideological rift began to open up between the missions and the new Black political beliefs of the Second World War. This led to the Lovedale Riot which is considered in the broader framework of sociopolitical unrest within the country. After the 1948 Election an ideological rift also developed between the missions and the State. This study concludes by examining the introduction of the Bantu Education Act and the Lovedale response to this. It was felt that although Bantu Education threatened to undermine their educational endeavour, they should nevertheless cooperate with the system in order to save what they had built up.

- Description: The disparate numbers of boys and girls who elect to continue with mathemalics and/or physical science in the higher slandards of the school system has recently attracted much research atlention and the complexity of the interrelaledness of causal factors has become obvious. The broad aim of the study was to investigale the significant drop-out rate of girls at the end of the junior secondary phase of education (approximate age of fourteen lo fifteen). This was to be carried out for mathematics and physical science and undertaken using a cross-sectional and a longitudinal study. The cross-sectional study entailed administering mathematics and physical science attitude questionnaires to 3531 standard six, seven and eight pupils from 4 co-educational, 2 allgirls' and 2 all-boys' schools, from middle and upper socioeconomic communities with similar language and cultural backgrounds . The longitudinal study involved pupils from two coeducational schools and one all-girls' school. It was a progressively-focused study starting with questionnaires administered to 358 standard six girls and boys, narrowing down to questionnaires and interviews used with 50 girls and 28 boys in standard seven and finally to interviews with 10 girls from standard eight. The parents of these ten girls were interviewed at the end of the study. The attilude questionnaires yielded strong sex differences which favoured the boys in both subjects for all the attitudes measured and also pointed to a progressive deterioralion of altitudes over the three-standard span. They also established significant differences in attitudes which favoured the pupils from Single-sex schools. It was further concluded that the girls were more strongly guided by their attitudes when making their subject-choice decisions. In the longitudinal study, reasons were suggested for pupils either taking or dropping mathematics and physical science. The introduction of algebra in the first year of high school presented a problem to pupils. In physical science, electricity was singled out as giving the subject a male bias. Socialization influences in the home were the main issue dealt with from the parent interviews . Sex-roles and stereotypes were dealt with in depth. Recommendations were made involving classroom strategies, curriculum possibilities, school policies and further research

- Description: Masculinity and femininity are taken for granted as being a natural part of everyday existence forming acceptable images of what it means to be a man and a woman. It is revealed that in conforming to the sexual stereotype of what it means to be masculine and feminine, men's repression of their emotional life forms a counterpart of their oppression of women, for the repression of men's emotional life as a process, manifests itself through the oppression of women. The socioeconomic relations, being exploitative in nature, having been obscured and mystified by masculine and feminine forms of false consciousness, justify the prevalent social circumstances by portraying them as natural and inevitable, thus serving to hide the fact that men and women comprise of both, masculine and feminine characteristics. Disclosing the quality of the experience of men's repression of their emotional life as a counterpart of their oppression of women, through qualitative description and reflection, it is evident that individuality and human social relationships are restricted by the constraints of masculine and feminine stereotypes. It is clearly highlighted, that women help to perpetuate the repression of male emotional life and in turn their own oppression through supporting the successful work, status and power oriented 'macho' male. Through the recognition of the pressures, and a re-evaluation of the masculine role, men will no longer see cause to oppress women and through that there will no longer be a need to repress their own emotional life. There is a need for self-reflection in those individuals and groups restricted by the constraints of masculinity and femininity for the realization of new possibilities of enlightened social action and individuality.

Never before have these elections been held together on the same day. That is about all that is historically "new" about the coming local authority elections. Yet to the government, the forthcoming municipal elections are all-important. So much so, that it is now an offense to call on people to boycott the elections. This booklet will attempt to find some explanations for why the coming municipal elections are so important to the government. How do they fit into the National Party’s political plans for the country and, most importantly, how do the majority of politically unrepresented South Africans view the elections and the structures of local government?

On a class of pseudo-differential operators in IRⁿ

- Description: The class of pseudo-differential operators with symbols from Sm (superscript) po̧̧ (subscipt)(Ωx IRⁿ) has been extensively studied.The main assumption which characterises this class of symbols is that a(x,Ȩ) є Sm (superscript)po̧̧ (subscipt)(Ωx IRⁿ) should have a polynomial growth in the Ȩ variable only. The x-variable is controlled on compact subsets of Ω. A polynomial growth in both the x and Ȩ variables on a C°°(lR²ⁿ) function a(x,Ȩ) gives rise to a different class of symbols and a corresponding class of operators. In this work, such symbols and the action of the operators on the functional spaces S(lRⁿ) , S'(lRⁿ) and the Sobolev spaces Qs (superscript) (lRⁿ) (s є lRⁿ) are studied. A study of the calculus (i.e. transposes, adjoints and compositions) and the functional analysis of these operators is done with special attention to L-boundedness and compactness. The class of hypoelliptic pseudo-differential operators in IRⁿ is introduced as a subclass of those considered earlier.These operators possess the property that they allow a pseudo- inverse or parametrix. In conclusion. the spectral theory of these operators is considered. Since a general spectral theory would be beyond the scope of this work, only some special cases of the pseudo-differential operators in IRⁿ are considered. A few applications of this spectral theory are discussed

Organisational structures for effective geography teaching in selected medium and large primary schools

- Description: Effective teaching is determined by a host of factors, not least of which is the educational guidance given to the teacher. This guidance should come about through an effecctively designed support structure initiated by the school principal as part of his management strategy. Very little has been written on this topic, particularly with reference to primary schools. In the past, geography teachers were trained, appointed to a school and expected to get on with their teaching. However, present-day teachers, in order to be effective educators, require in-service training. This should occur In a variety of ways and on a continuous basis, because teaching is an on-going business and not a job to be learned once and for always. This thesis investigates the organisational structures that exist for the teaching of geography in selected medium and large primary schools in the Eastern Cape. The author found that principals used either a subject head or standard head model. In large primary schools a subject head model was preferred i.e. a specialist geography teacher was responslble for developing the subject vertically from standard 2 to 5. The opposite was true in medium-sized schools. Principals of these schools preferred to delegate responsibility to a standard head. It was the duty ot the standard head, usually a generalist teacher without specific training in geography, to develop geography horizontally among, for example, all the standard 3 pupils. The role played by key members of a primary schools' instructional leadership team, namely the principal, subject head, and the standard head are examined in detail. The author offers justification why geography should be included In the primary curriculum. It is his contention that geography contributes to a child's general education, develops basic geographical skills, extends general mental abilities and fosters positive attitudes towards other people with whom he shares this world. A management model is proposed for principals, flexible enough for application in all schools. It is designed to ensure that teachers continue growing professionaIIy within the structure of a small group. There is no best way to organise the teaching of geography because each school has its own unique resources which should be optimally utilised in order to bring about learning. The professional development of geography teachers is possible because someone competent in geographical education should assume leadership of the qroup. This will enable ideas to be shared, plans made and strategies implemented in an eftort to improve teacher-competence through an efficiently organised geography department. In the final chapter conclusions are drawn and a recommendatlon is made for primary school principals to Implement an organlsatlonal model for the teaching of geography. A choice may be made from three models, namely a standard head, subject head or a comblnation of both models. It Is within the parameters of one of these structures that the subject can be properly managed, for example, field-trips planned, teaching aids purchased, envlronmental educatlon programmes designed, teaching strategies discussed and examinat(ons set. Thls view is supported by Cawood and GIbbon's (1980) empirical evidence. They found that good educatlonal leadership fosters effective teaching in schools.

- 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.

The results of the trial indicated that the 0.1% desonide cream falls into the potent group of topical corticosteroid preparations and the 0.05% halomethasone cream falls into the moderately potent group.
