- Description: Affirmative action is a sensitive and controversial topic evoking a host of emotional reactions regarding tokenism, reverse discrimination, lowering of standards, quota systems and a disregard for meritocracy (Gatherer & Erikson, 1992). It is also a topic receiving considerable attention in the context of a changing South Africa and will be one of the first steps taken in the labour arena under a new government (Charoux, 1991 ). The goals of the research were firstly, to detail and compare the attitudes of men and women, black and white to affirmative action and secondly, to examine the perceived impact of an affirmative action programme on beneficiaries as well as non-beneficiaries. The research was of a quantitative and qualitative nature, so as to provide the scope and depth desired in such an investigation. A survey was conducted using the data collection techniques of a mail questionnaire (quantitative focus) and individual in-depth interviews (qualitative focus). A pilot study was conducted. The majority of the questions in the questionnaire conformed to the conventions of the Likert Scale (Oppenheim, 1992) and data was analysed using percentile frequencies. Data from the interviews was analysed using the qualitative methods of noting themes and patterns, and clustering as proposed by Miles and Hubem1an (1984). The research was conducted in one large organisation in the infomation services industry, situated in the PWV area. Four key sample groups of white men, white women, black men and black women were used. The results of the research indicate that respondents perceive affirmative action as a policy to primarily address the educational disadvantages of black people in South Africa. Initial attitudes to affirmative action reflected a negative orientation amongst whites but a positive orientation amongst blacks. However, probing into the issues indicated that whilst there is an acceptance of the philosophy of and the need for affirmative action for black people, disagreement existed over which implementation methods of affirmative action (preferential treatment and quota systems) were acceptable and at what interfaces (hiring, training and development, promotion), implementation was acceptable. Attitudes on these various issues were often not divided along racial or gender lines and considerable divergence of attitudes also existed within the sample groups. Gender in affirmative action received less consideration by all four sample groups. Results also indicate that beneficiaries of affirmative action do not perceive affirmative action policies and programmes as stigmatising or negatively affecting their self-esteem. Nonbeneficiaries communicated that affirmative action could result in white resentment if blacks benefit at the expense of whites. Low levels of resentment were evident in the research. The organisation's affirmative action programme was seen to be ineffective due to the lack of communication about the programme, no evidence of its progress in terms of significant representation of blacks at senior levels in company XXX and the inequities that were seen to be still pervading the organisation.

- Description: The neoclassical "sources-of-growth" approach is applied to derive total factor productivity (TFP) growth measures for manufacturing industries in South Africa. Although South Africa's recorded industrial TFP growth measures have been persistently low in absolute terms, this performance is not significantly worse than the industrial TFP growth performance of other developing countries. In some periods there is evidence of a significant variability in TFP performance across industries. The measures also indicate that TFP growth has worsened in the 1980s, particularly in the intermediate-capital intensive and labour intensive industries. However, there are various problems with interpreting neoclassical TFP growth measures as indicators of production efficiency. In fact, as TFP growth is derived as a residual, it may measure many factors besides production efficiency. Alternative growth theories are used to assess the fundamental determinants of productivity growth. These provide a more plausible conceptualisation of the process by which productivity growth is generated than the neoclassical growth theory does. However, this analysis also provides little empirical evidence of which underlying factors have had the most influence on productivity growth in South African manufacturing. Hence, the relative importance of possible candidates can only really be assessed qualitatively and on the basis of micro evidence. However, these assessments, and the assumptions underlying the postulated causal connections (between the identified factors and productivity growth), have a major impact on policy design. In this respect, on the basis of the framework provided by the evolutionary and other recent growth theories, various policy implications are drawn, and these are contrasted with the policy proposals of other South African analysts. This thesis concludes that policies need to be designed with the central objective of enhancing the technological capabilities of South African firms. Trade policies will not be sufficient for achieving this objective. Education and training policies, technology, competition and labour market policies are also crucial. However, since the fundamental causes of productivity growth remain somewhat of a mystery, there is a need to be sceptical of simple policy prescriptions. In this respect, this thesis is highly critical of the World Bank's position that productivity gains will be reaped from the exposure of firms to international competition that trade liberalisation policies entail.

- Description: This study analyses the methods and policies of the colonial government which shaped Stutterheim's African communities between c.1870 and 1910. In 1870 the Stutterheim magisterial district had not yet been officially established. However, creation of the British Kaffrarian administration (1847-1865) had already ensured the entrenchment of colonial rule over the humiliated Xhosa chiefdoms west of the Kei. This work studies transformations in late colonial Ngqika society and the development of Stutterheim as a magisterial district. It analyses the entrenchment of colonial bureaucracy and changes in indigenous social, economic and political structures. In the period c.1860-1877, direct administration of the Ngqika was first attempted. While recovering from the 1856-57 cattle killing, the Ngqika were brought under colonial administration by the annexation of British Kaffraria to the Cape Colony in 1865. The thesis also examines the process and implications of the breakup and resettlement of the Ngqika location after the 1877-1878 war and the mechanisms and complications in forming a new postwar settlement. The focus then narrows to Stutterheim magisterial district (finalised in 1880), where, after the removal of the main Ngqika population to the Transkei formal structures of quitrent settlement were established around mission stations. A new form of social behaviour underpinned by principles of individualism evolved under missionary influence. Urged on by legislation that sought to intensify implementation of individual tenure, this social behaviour predominated under the new administration. Attention is also given to the allocation of farm land in the district. On part of what had once been communally owned land, an immigrant farming community originally intended strictly for whites emerged. Numerous Africans later managed to hold property in this area. An urban area with a mixed African and white population resulted where allotments initially allocated to the German Legion were later auctioned. On crown lands, leasing and purchasing was initiated. By the early twentieth century, settlement patterns were in chaos: on the mission settlements, quitrenters disobeyed settlement regulations, farms were overpopulated by tenants and interracial urban settlements faced imminent segregationist policies. By 1910 local administration was in difficulties and the Africans were becoming politically mobilised against local and colonial policies.

- Description: This study applies Sperber and Wilson's relevance theory to the comprehension of figurative language in poetry. Students' understanding of metaphor as a linguistic category and comprehension of metaphorical texts are analysed in terms of the principle of relevance. Patterns of comprehension in English first language (Ll) and English second language (ESL) students' analyses of metaphorical texts are discussed and through an analysis of similarities and differences in these patterns of comprehension an attempt is made to develop a pedagogy around relevance theory. Relevance theory's particular emphasis on the role played by "context" in cognition is seen to have significance for the teaching of literature in South African universities. Relevance theory's account of cognition generates a range of educational principles which could be specifically applied to the teaching of metaphor. An appraisal of the strengths and difficulties students experience in expressing their understanding of metaphor in an academic context is included. This was done to further develop relevance theory into a pedagogical approach which takes into account the academic context in which writing occurs. The investigation of the particular difficulties that English metaphor poses for ESL students entailed acquiring a working knowledge of the ways in which metaphor is taught and assessed in DET schools. The interpretations of students of different linguistic, social and educational backgrounds reveal unifying elements that could be incorporated into a pedagogy based on relevance theory. Such a pedagogy would be appropriate to the multilingual/multicultural/multiracial nature of classes in South African universities and would be a more empowering approach to the teaching of English metaphor.

- Description: The investigations presented in this thesis form part of a systematic international effort to establish the structures of the capsules produced by the bacterial genera, Escherichia coli and Klebsiella (family enterobacteriaceae). These bacteria are of medical interest as they are opportunistic pathogens and are frequently responsible for serious infections in animals and man. Invasive strains are invariably surrounded by a structurally complex polysaccharide capsule which contributes to the organism's ability to attenuate non-specific host defence mechanisms or, in some instances, to completely prevent an immune response. A knowledge of the chemical composition and structure of the capsule is, therefore, of great value as it provides insight into the mechanisms involved in this process. The E. coli, in particular, have generated considerable interest as their capsules are more structurally diverse and cross-reactivity with other, more pathogenic bacteria has also been demonstrated. Accordingly, the structures of three previously unstudied E. coli K-antigens viz. those produced by serotypes 020:K83:H26, 020:K84:H26, and 09:K48:H9 have been established by chemical and spectroscopic means and are presented in this thesis. In addition, a reinvestigation of the structure of the capsule produced by Klebsiella K15 using a novel enzymatic approach was also undertaken and a revised structure is proposed . The E. coli K48 polysaccharide is of special interest as it was found to contain a new diacetamido trideoxy hexose hitherto unrecorded. A synthesis for this saccharide is also presented. Finally, the application of lithium dissolved in ethylenediamine for the degradation of amino sugar-containing polysaccharides was also investigated using the capsular polysaccharides produced by E. coli serotypes K38 and K84 as model compounds.

The relationship between daily and monthly pan evaporation and rainfall totals in Southern Africa

- Description: Recent droughts in South Africa have highlighted the vulnerability of the economy to water restrictions. However, the degree of surface aridity in southern Africa is not only a function of precipitation, but also one of evaporation. The quantitative assessment of evaporative loss is important since it is a major component of the water budget. For example, in southern Africa, evaporation accounts for 79.5% of the hydrological water budget. As the cost of water resource development increases, so there has been an increasing demand for hydrological modelling to optimise project planning. Reliable estimates of evaporation are essential to significant improvements in the practice of hydrology and particularly in a country like South Africa which is prone to the adverse effects of drought. It is difficult to adequately measure potential evaporation over an area as large and as sparsely populated as southern Africa. Despite the research that has been undertaken to estimate evaporation from related meteorological and physical variables, generally, the estimation of evaporation in southern Africa has been unsatisfactory. There are a number of methods for estimating potential evaporation. However, a major problem tends to be the incompatibility between the data requirements of some of the more physically-based models, and the actual data that is available and collected on a routine basis at a sufficient number of stations. In existing water resources estimation models, evaporation is often incorporated as a time series input of pan evaporation, using daily or monthly values. The lack of a nearby record of pan evaporation often necessitates the use of published regionalised mean monthly pan values. This technique of using the mean monthly evaporation values in water resources estimation models tends to overestimate or underestimate the actual evaporation that is occurring, depending on the actual amount of rain occurring in a specific month. This is because no attempt has been made to correct these mean evaporation values for the amount of rainfall that occurs in a specific month, in a specific region. The regional rainfall/evaporation relationships (that vary spatially and temporally) are not taken into account. A need was identified for an assessment of the value of grouping data by rainfall as a better tool for estimating evaporation. Here, the monthly evaporation and the mean monthly evaporation for a specific rainfall group category will be estimated using daily data. Due to data availability, the most appropriate time scale to use is one day. Therefore, in this study an attempt has been made to relate rainfall amounts to evaporation values and to develop rainfall/evaporation relationships, identifying variations by season and region. It is important to identify and quantify these relationships and assess the possibility of incorporating these variations into existing Water Resource Estimation Models. The ability to derive and develop meaningful relationships between daily rainfall and daily evaporation for each season, and for a number of sites considered representative of the climatological zones for southern Africa was assessed. The first approach was to compare daily evaporation plotted against daily rainfall, and in the process develop a quantitative rainfall/evaporation relationship. Unfortunately, no direct linear relationships were identified. The second approach was to test the performance of the water resource estimation model using the following possible choices, (i) a real daily input (COREVAP1) - here the estimated monthly evaporation is the sum of the product number of days within each month * mean daily evaporation for each specified raingroup category, (ii) a distributed mean monthly input (COREVAP2) - here evaporation is estimated using a random sampling procedure to draw samples from a restricted part of the daily evaporation distribution for each raingroup and is defined by the mean and standard deviation, and (iii) a distributed mean monthly input and correction (COREVAP3) - here samples are drawn from the full distribution of daily evaporation for each raingroup category. The performance of the COREVAP programs was analyzed in terms of the improvement effected by estimating evaporation using the mean monthly evaporation regardless of rain. COREVAP1 produced the best simulations of monthly evaporation. This was expected as the program uses the straight-forward mean evaporation value multiplied by the number of days to simulate the monthly evaporation values. However, the COREVAP programs did not perform well when using the monthly evaporation data based on daily infilled values using the transformed parameters. Any regionalisation of parameter files would mean that a range of parameters in a region would now be represented by a single value. The need to assess the effect of this change from a regional range of values to a single representative value was identified. This was done by conducting a sensitivity analysis, in terms of what effect a percentage increase or decrease in the lambda, mean evaporation and mean rainfall values would have on the resultant simulated monthly evaporation and coefficient of efficiency values. A sensitivity analysis was conducted on COREVAP1 to determine which parameters of the model had the greatest influence on the simulations. This was done with reference to the percentage error of monthly evaporation and the monthly and accumulative coefficient of efficiency values. Generally, the percentage increase/decrease in mean evaporation values that are acceptable for the representative stations are low. In contrast, fairly high percentage changes in mean rainfall values are tolerated. The objective of the regionalisation of parameters was to determine whether general characteristics can be applied to some stations that are significantly different compared to other stations, so that the stations may be combined to represent a separate region. The demarcation of regions was conducted on the basis of the regional relative mean evaporation values (per raingroup, per season), the daily mean evaporation values per month and the average number of days within each raingroup, per season. Intra-station and inter-region variability was analysed using the Kruskal-Wallis H test and the Friedman Fr test. The regional parameters were then used as input into the COREVAP programs and the simulation results were analysed in terms of whether the simulations still produce positive accumulative coefficient of efficiency values. The results obtained when substituting the regional parameters were not good. Based on these results, it has been concluded that the hypothesis that grouping data by rainfall may be a better tool for estimating evaporation compared to simply using the mean monthly evaporation, may be rejected.

However, a major problem tends to be the incompatibility between the data requirements of some of the more physically-based models, and the actual data that is available and collected on a routine basis at a sufficient number of stations. In existing water resources estimation models, evaporation is often incorporated as a time series input of pan evaporation, using daily or monthly values. The lack of a nearby record of pan evaporation often necessitates the use of published regionalised mean monthly pan values. This technique of using the mean monthly evaporation values in water resources estimation models tends to overestimate or underestimate the actual evaporation that is occurring, depending on the actual amount of rain occurring in a specific month. This is because no attempt has been made to correct these mean evaporation values for the amount of rainfall that occurs in a specific month, in a specific region. The regional rainfall/evaporation relationships (that vary spatially and temporally) are not taken into account. A need was identified for an assessment of the value of grouping data by rainfall as a better tool for estimating evaporation. Here, the monthly evaporation and the mean monthly evaporation for a specific rainfall group category will be estimated using daily data. Due to data availability, the most appropriate time scale to use is one day. Therefore, in this study an attempt has been made to relate rainfall amounts to evaporation values and to develop rainfall/evaporation relationships, identifying variations by season and region. It is important to identify and quantify these relationships and assess the possibility of incorporating these variations into existing Water Resource Estimation Models. The ability to derive and develop meaningful relationships between daily rainfall and daily evaporation for each season, and for a number of sites considered representative of the climatological zones for southern Africa was assessed. The first approach was to compare daily evaporation plotted against daily rainfall, and in the process develop a quantitative rainfall/evaporation relationship. Unfortunately, no direct linear relationships were identified. The second approach was to test the performance of the water resource estimation model using the following possible choices, (i) a real daily input (COREVAP1) - here the estimated monthly evaporation is the sum of the product number of days within each month * mean daily evaporation for each specified raingroup category, (ii) a distributed mean monthly input (COREVAP2) - here evaporation is estimated using a random sampling procedure to draw samples from a restricted part of the daily evaporation distribution for each raingroup and is defined by the mean and standard deviation, and (iii) a distributed mean monthly input and correction (COREVAP3) - here samples are drawn from the full distribution of daily evaporation for each raingroup category. The performance of the COREVAP programs was analyzed in terms of the improvement effected by estimating evaporation using the mean monthly evaporation regardless of rain. COREVAP1 produced the best simulations of monthly evaporation. This was expected as the program uses the straight-forward mean evaporation value multiplied by the number of days to simulate the monthly evaporation values. However, the COREVAP programs did not perform well when using the monthly evaporation data based on daily infilled values using the transformed parameters. Any regionalisation of parameter files would mean that a range of parameters in a region would now be represented by a single value. The need to assess the effect of this change from a regional range of values to a single representative value was identified. This was done by conducting a sensitivity analysis, in terms of what effect a percentage increase or decrease in the lambda, mean evaporation and mean rainfall values would have on the resultant simulated monthly evaporation and coefficient of efficiency values. A sensitivity analysis was conducted on COREVAP1 to determine which parameters of the model had the greatest influence on the simulations. This was done with reference to the percentage error of monthly evaporation and the monthly and accumulative coefficient of efficiency values. Generally, the percentage increase/decrease in mean evaporation values that are acceptable for the representative stations are low. In contrast, fairly high percentage changes in mean rainfall values are tolerated. The objective of the regionalisation of parameters was to determine whether general characteristics can be applied to some stations that are significantly different compared to other stations, so that the stations may be combined to represent a separate region. The demarcation of regions was conducted on the basis of the regional relative mean evaporation values (per raingroup, per season), the daily mean evaporation values per month and the average number of days within each raingroup, per season. Intra-station and inter-region variability was analysed using the Kruskal-Wallis H test and the Friedman Fr test. The regional parameters were then used as input into the COREVAP programs and the simulation results were analysed in terms of whether the simulations still produce positive accumulative coefficient of efficiency values. The results obtained when substituting the regional parameters were not good. Based on these results, it has been concluded that the hypothesis that grouping data by rainfall may be a better tool for estimating evaporation compared to simply using the mean monthly evaporation, may be rejected.

- Description: In the endeavour to abolish from society all forms of ideologies that prescribe the domination of one sex over another, it has become increasingly important to analyse the representation of women in dramatic literature because dramatic literature reflects the philosophies and codes of behaviour which enable individuals to dominate one another in society, and assists in either reinforcing old ideologies or shaping new ones. Although Sam Shepard has been an influential force in the creation of modern drama, his plays reflect a patriarchal ideology that dictates that women are subordinate to men. Shepard's plays dramatise various male predicaments and his female characters are constructed and utilised to express men's experience, not women's. One of the conflicts which besets the male characters is that they desire to return to the womb of the mother, but simultaneously fear that their identities will be engulfed by the mother. In The Rock Garden, Red Cross and Fourteen Hundred Thousand, these desires and fears are demonstrated through the female characters, who are manipulated to represent objects of male desire and/or objects onto which devouring images are projected. Women are therefore represented in a manner in which they are best able to express the male characters' identity related conflicts. In Curse of the Starving Class and Buried Child, characters suffer from receiving insufficient nurture, are spiritually and emotionally impoverished or cursed and appear unable to transform their lives. The female characters are presented as being partly responsible for causing these predicaments since their nurturing, generative and transformative abilities are presented in a negative light. Women are also represented as objects of blame in the male characters' attempts and failures to undergo rebirths and are once again created to express male predicaments. In Fool for Love and A Lie of the Mind, Shepard focuses on the relationships between men and women, but is only able to present the male characters' perspectives and represent male desire. The female characters are regarded, and engaged with, as reflections of the male characters' selves and are frequently utilised to express male desire. If Shepard's plays are persistently applauded and seen as examples to be emulated, we need to closely analyse these dramas that represent women in a manner which expresses male predicaments and which places them in roles that allow men to dominate them.

- Description: Fifty pre-pubescent Xhosa-speaking children from two primary schools within the township of Rini, Grahamstown, were selected in this study to determine the effects, if any, of an enriched physical activity programme. Subjects were divided into experimental and control groups with only the experimental group physically participating in the enrichment programme. Selected anthropometric, physiological and motor performance tests were administered on both groups, before and after the programme, to monitor the effect of the enrichment programme on growth, cardiovascular efficiency and physical performance. Somatotype ratings showed no change after the training programme. However body composition showed greater gains in fat mass in the control group and marked drops in fat mass and increases in lean body mass in the experimental group. Longer running distances, higher predicted VO2 max mean values and improved recovery heart rate (HR) as well as larger gains in relative power, absolute power and velocity were experienced by individuals who participated in the training programme. The performance of the experimental group in the two motor performance tests out-weighed by far the performance of the control group as a result of the additional programme. The enrichment programme not only produced a positive effect on body composition but also improved aerobic and anaerobic efficiency. Improvements in both motor performance tests favoured the experimental group.

- Description: This study attempted to characterise 5 field stocks of B. canis, collected from various geographic areas of southern Africa in terms of pathogenicity, immune response, cross resistance and antigenic composition. This was done by means of artificial infection of two to four year old Beagle dogs. Serological tests included indirect fluorescent antibody tests, polyacrylamide gel electrophoresis , Western blotting of B. canis antigen and immune serum transfers. The ZIM1, GHT1 , QTN1 and DBN1 stocks were found to be virulent and the JHB1 stock, which might be a cardiac form of babesiosis, was found to be highly virulent. Immune responses of dogs to primary challenges were poor. A second challenge or relapse was important in the development of a resistant immunity. Heterologous challenges showed that dogs which were immune to the ZIM1, QTN1 and DBN1 stocks were partially immune to the JHB1 stock. The dog that was immune to the GHT1 stock was the only one that was totally resistant to the JHB1 stock. Western blots revealed interstock antigenic variation between the JHB1 and the other four stocks. These differences were, however, not great enough to separate the stocks taxonomically.

- Description: This study examined: the features and extent of the gait velocity decrement following stroke; the nature of the balance disorder and; investigated relationships between gait and balance. Twenty, fully-ambulant, hemiplegic subjects (12 men and 8 women), with a mean age of 57.2 years (± 10.7), were compared with 20 age- and sex-matched controls. Spatiotemporal gait kinematics were measured at five walking speeds ranging from "very slow" to "very fast". Balance was then measured while subjects maintained a variety of weight shift postures both with feet parallel and then in diagonal positions similar to those assumed during the double support phases of gait. Location and variability of centre of pressure (CP) were measured and the ranges over which CP could be shifted were calculated. Stroke subjects walked very slowly with their "fastest" walking speed (0.5 stat/s ± 0.23) no different from the "slowest" speed (0.38 stat/s ± 0.11) of the controls (p > 0.05). Differences between the other parameters were also found, many of which could be attributed to the differences in walking speeds. However, where the subjects walked at similar velocities, the hemiplegic sample walked with quicker and shoner strides suggesting a "cautious" gait pattern. The single support asymmetry of the strokes decreased with increasing walking speed. The positions of CP in the hemiplegic sample were found to be significantly displaced towards the unaffected leg and deficiencies were found in posterior shifts (p < 0.05). Postural sway was significantly greater in the hemiplegic sample implying less stable balance and the ranges over which the hemiplegic sample shifted weight were significantly less than the controls. The diagonal weight shift tests revealed the difficulty the stroke subjects experienced in shifting CP posterolaterally over the affected leg. Significant correlations were detected confmning the presence of relationships between static balance performance and gait. However, these correlation findings left considerable percentages of variance unexplained. These findings suggest that future rehabilitation should address the poverty of range of walking speed possessed by hemiplegic subjects as well as the reduced ability to weight shift over the hemiplegic limb, particularly posterolaterally. Further study to test these proposals is indicated.

The morphology of the reproductive tract of the species was generally similar to that of other molossids, however, the absence of Cowpers glands was unusual. Spermatogenesis began in February and spermatozoa were released to the cauda epididymis during August and September. Follicular development started in March and culminated with the appearance of Graafian follicles in July. Ovulation probably occurred in August and specimens were pregnant by September. Gestation length was estimated to be four to five months and a single young was born in December. The data suggest that T. aegyptiaca is monotocous and monoestrous.

- Description: The Religious Society of Friends, or Quakers, began their witness in the 1600s during a time of religious debate when competing doctrines reflected the political, social and intellectual turmoil of seventeenth-century England. George Fox (1624-1691), the founder, preached that people are guided by God's inner light which is present in the hearts and conscience of all people and reflects God's 'divine' will. The Quakers form a small religious membership not larger than 200,000 people sect, its world-wide. Yet, historically, the group's impact on social issues has always outweighed its numerical strength. The earliest Quakers to reside more permanently in South Africa were British settlers, several of whom became outspoken civic leaders. Quaker humanitarian gestures led to the opening of a multi-racial school for poor children in Cape Town (1840) and investigations into the treatment of Afrikaner women and children in concentration camps during the Anglo-Boer War (1899-1902). Early Quakers are also credited with initiating the Joint Council Movement of Europeans and Africans (1920s), forerunner to the South African Institute of Race Relations. This study traces the Quaker presence in South Africa from its earliest history to the present, with particular emphasis on the twentieth century. Specifically, the examination of the Quaker presence addresses the group's reaction to South African society and politics in reference to segregationist and apartheid legislation. The study includes a comparative analysis of the response among South African Quakers to these issues with Quaker response in England and the United states. The purpose of this analysis is to attempt an assessment of the extent to which South African Quaker practices were consistent with the philosophies of their world-wide religious fellowship. Relevant to the Quaker belief in peace and justice for all, with no discrimination, specific issues that involved South African Quakers and for which sufficient primary sources were available are closely examined. Of particular interest is the opening of a Quaker boarding school during the early 1930s, the Quaker response to the Defiance Campaign in 1952, and South African Quaker response to the call for international sanctions and boycotts against South Africa. More recent Quaker activities, including mediation between the African National Congress and the government, provide significant data. South African Quakers have defined themselves as members of a religious body whose belief of pacifism and commitment to non-violence dictates to a certain extent their obedience to a higher authority -- which some call their conscience and others call God -- if a civil law is deemed immoral and unjust . Thus, the study seeks to define the individual and corporate Quaker witness in South Africa in relation to the Society's principles.
