- Description: Background: People with physical limitations can contribute significantly to society and the economy, however, barriers to full and effective participation in the labour market often hinder decent employment. In light of this, placement decisions of impaired workers should be based on detailed information of the nature of the jobs available, as well as individual capabilities of the worker. An ergonomics approach to design attempts to achieve an appropriate balance between the capabilities of the worker and the requirements of the task and uses this balance to improve productivity and encourage physical and mental well-being, job satisfaction and safety. A specific analysis tool which can be applied to various workplaces and jobs, and provide information for decisions regarding placement of physically limited workers, will help to increase the percentage of correct placement in an appropriate workplace, resulting in optimum productivity and worker safety. Methods: An assessment tool which allows matching of job requirements and worker capabilities was developed based on a theoretical framework from Mattison and Goebel (2007), as well as principles defined by Almgren and Schaurig (2012) and Demura and Nakada (2010). The tool assesses range of motion, force and time components of the physical requirements of different tasks involved in the job, as well as movement capabilities and limitations of the worker. The tool was pilot tested in a case study with an above the knee amputee working at a research facility. Results: The tool successfully provided information regarding the matching of the work to the identified job. The output of the tool highlighted two tasks which would place the worker at risk due to physical requirements of the tasks being greater than movement capabilities of the worker. These tasks need to be further investigated to determine if accommodations can be made to assist the worker in safely performing the task, or if the job is not suitable for the worker. Conclusions: The tool developed was useful in providing information to inform appropriate placement of the physically limited worker. Further research needs to be done to validate and determine reliability of the tool.

- Description: The aim of this qualitative study was to gain an understanding of the factors that enhance truck driver retention at Tanker Services, Imperial Logistics, South Africa. The specific objectives of the study were to (1) explore factors which influence the retention of truck drivers from the perspectives of immediate supervisors of these drivers at Tanker Services Branches in Durban, Johannesburg, and Cape Town; (2) to identify the means Tanker Services adopts in meeting factors influential to truck driver retention; and (3) to provide recommendations on how to successfully retain truck drivers in this logistics organisation in South Africa. The research methodology of this study involved interviewing ten immediate managers of truck drivers at Tanker Services, Imperial Logistics. Specifically, data was collected through the use of individual, in-depth and semi-structured interviews to investigate the most influential factors affecting truck driver retention. The results of this research outline factors important to the truck drivers at Tanker Services from the perspectives of their immediate supervisors - most of whom were previously truck drivers themselves. The findings of this research identified the general factors that affect Tanker Services Truck drivers as follows: formal and informal rewards, competitive compensation, a work environment of quality equipment, high safety standards and recreational facilities. Furthermore, interpersonal relations and company reputation were found most influential to truck drivers in this South African logistics context.

- Description: Phishing in the electronic communications medium is the act of sending unsolicited email messages with the intention of masquerading as a reputed business. The objective is to deceive the recipient into divulging personal and sensitive information such as bank account details, credit card numbers and passwords. Attacks against financial services are the most common types of targets for scammers. Phishing attacks in South Africa have cost businesses and consumers substantial amounts of financial loss. This research investigated existing literature to understand the basic concepts of email, phishing, spam and how these fit together. The research also looks into the increasing growth of phishing worldwide and in particular against South African targets. A quantitative study is performed and reported on; this involves the study and analysis of phishing statistics in a data set provided by the South African Anti-Phishing Working Group. The data set contains phishing URL information, country code where the site has been hosted, targeted company name, IP address information and timestamp of the phishing site. The data set contains 161 different phishing targets. The research primarily focuses on the trend in phishing attacks against six South African based financial institutions, but also correlates this with the overall global trend using statistical analysis. The results from the study of the data set are compared to existing statistics and literature regarding the prevalence and growth of phishing in South Africa. The question that this research answers is whether or not the prevalence and growth of phishing in South Africa correlates with the global trend in phishing attacks. The findings indicate that certain correlations exist between some of the South African phishing targets and global phishing trends.

- Description: Reliability life testing is used for life data analysis in which samples are tested under normal conditions to obtain failure time data for reliability assessment. It can be costly and time consuming to obtain failure time data under normal operating conditions if the mean time to failure of a product is long. An alternative is to use failure time data from an accelerated life test (ALT) to extrapolate the reliability under normal conditions. In accelerated life testing, the units are placed under a higher than normal stress condition such as voltage, current, pressure, temperature, to make the items fail in a shorter period of time. The failure information is then transformed through an accelerated model commonly known as the time transformation function, to predict the reliability under normal operating conditions. The power law will be used as the time transformation function in this thesis. We will first consider a Bayesian inference model under the assumption that the underlying life distribution in the accelerated life test is exponentially distributed. The maximal data information (MDI) prior, the Ghosh Mergel and Liu (GML) prior and the Jeffreys prior will be derived for the exponential distribution. The propriety of the posterior distributions will be investigated. Results will be compared when using these non-informative priors in a simulation study by looking at the posterior variances. The Weibull distribution as the underlying life distribution in the accelerated life test will also be investigated. The maximal data information prior will be derived for the Weibull distribution using the power law. The uniform prior and a mixture of Gamma and uniform priors will be considered. The propriety of these posteriors will also be investigated. The predictive reliability at the use-stress will be computed for these models. The deviance information criterion will be used to compare these priors. As a result of using a time transformation function, Bayesian inference becomes analytically intractable and Markov Chain Monte Carlo (MCMC) methods will be used to alleviate this problem. The Metropolis-Hastings algorithm will be used to sample from the posteriors for the exponential model in the accelerated life test. The adaptive rejection sampling method will be used to sample from the posterior distributions when the Weibull model is considered.

- Description: The PR851 licence area is located at about 80 km west from the town of Likasi in the district of Haut-Katanga and 175 km north-west of Lubumbashi, the capital city of Katanga Province in the Democratic Republic of Congo. The exploration licence was granted by the government of the Democratic Republic of Congo to First Quantum Minerals Ltd through its Congolese subsidiary Compagnie Minière de Sakania Sprl (CoMiSa Sprl) under certificate N˚ CAMI/CR/70/2003 on the 10th of October 2003 for a period of 5 years with a possibility of renewal for 3 years in respect to the new Congolese mining code. The PR851 area lies on fragments of Mines Subgroup rocks of the Roan Group in the Congolese Copperbelt where most of the Cu-Co and stratiform-stratabound deposits such as Kipushi, Ruashi-Etoile, Kinsevere, Kipoi, Luishya, Luswishi, Shituru, Kamoya, Kambove, Tenke- Fungurume, Shinkolobwe, Swambo, Mindingi and Kamoto among others are found. During the 20th century, the Union Minière du Haut Katanga (U.M.H.K.) undertook mineral exploration in the Congolese Copperbelt and numerous copper- and cobalt-occurrences were identified (for instance Kibamba copper occurrence in PR851 area). From 2003, the Compagnie Minière de Sakania Sprl initiated a grassroots exploration program in PR851 area and geochemical exploration survey as one of the mineral exploration tools was implemented to aim at detecting copper and cobalt concentration in soil. The B horizon of the thick tropical soil in the area was sampled and soil samples were sent to Genalysis laboratories in Johannesburg, Republic of South Africa for main chemical analysis of Cu and Co only, whereas 10% of analyzed samples were dispatched to Perth, Western Australia for quality control analysis. Thresholds for anomalies of copper and cobalt were defined by literature comparison, standard deviations and spatial analysis. The anomalies were tested at a later stage by reverse circulation / diamond drilling during the year of 2005 to 2008 and the Cu-Co resources were estimated by Digital Mining Services of Harare, Zimbabwe in the year of 2008. Geological logging of chips from reverse circulation and diamond drill cores revealed that copper mineralization is represented by malachite, chrysocolla, chalcopyrite and bornite whereas cobalt mineralization appeared in form of heterogenite. The source of supergene mineralization remains unknown. Recommendations have been made to undertake more geological exploration work in order to fully investigate the geological setting and structural architecture of the region, which may result in a better understanding of the Cu-Co mineralization system and ore genesis. The latter has been no consensus up-to-date and different theories have been proposed to discuss the ore genesis, including syn- and dia- genetic, synorogenic and sulphide remobilization to late-to-post- orogenic Cu-Zn-Pb Kipushi-type deposit. However, geological observations favored that the diagenetic and syngenetic models are applicable to numerous deposits in the Central African Copperbelt.

- Description: Since the first period of the Kyoto Protocol, there has been a growing concern that the burden of reducing greenhouse gas emissions should not only be borne by developed countries, but developing countries as well. South Africa, as the 18th highest emitter of greenhouse gases in the world and highest in Africa, has a significant responsibility to reduce its emissions levels. The South African government is currently in the process of implementing a carbon tax for its short term response to climate change and considering the implementation of a carbon market as a medium to long term response to climate change. Both of these market based mechanisms are widely deemed effective in the mitigation of greenhouse gas emissions by economists, however are also known to have negative social and economic implications upon an economy. This study identifies these implications and attempts to provide considerations on how to alleviate the implications through the most appropriate process of revenue recycling. The negative effects of Implementing a carbon tax or carbon market could be severe as and not limited to: a significant decline in GDP, a reduction in the standard of living for certain households, a fall in a country's exports and even an increase in poverty. South Africa's environmental and development policies place a strict precedence on the protection of the poor and the prevention of economic hardship induced by such policies. This places significant importance on the prevention of these externalities from occurring. A primary means of doing so is through the process of revenue recycling, however, certain channels of revenue recycling are by no means helpful, hence the most appropriate channel needs to be identified. The study carried out a multiple case study analysis on Ireland, Mexico, New Zealand and Norway, to determine what effects a carbon tax had on their economies and how these effects were mitigated through carbon tax revenue recycling. An additional analysis of the EU ETS was carried out to determine how the EU ETS was implemented and the controversies and concerns that arose during its implementation. The findings of this analysis were then compared to a number of South African economist’s case studies, and the most appropriate method of revenue recycling identified and possible solutions to the EU ETS controversies found. The study concludes that a food subsidy has the potential to provide positive effects on welfare employment and GDP; therefore could be considered to be the most appropriate method of revenue recycling. However, these effects are limited to be experienced only at low levels of a carbon tax, hence, short term in nature. The study therefore provides a further consideration that the use of multiple channels for revenue recycling needs to be explored that could provide stable longer term effects. In addition, in the implementation of a carbon market, the study concludes that government should consider using an auction approach in the initial allocation phase of an ETS and the use of a centralized registry for monitoring and controlling of information and transactions.

- Description: The purpose of this study was to gain insight into observed discrepancies between continuous assessment and final examination average marks in Grade 10 Mathematics in the Oshikoto region of Namibia. The study is framed as a case study and is grounded within the interpretive paradigm. A mixed methods approach was applied, eliciting both quantitative as well as qualitative data. The study took place in two phases. In Phase 1, continuous assessment and Grade 10 final examination average marks for 62 Junior Secondary Schools for the period 2008-2010 were gathered and analyzed. Schools were characterized in terms of the relationship between their continuous assessment and final examination average marks for each of the three years. Phase 2, which was informed by Phase 1, took the form of structured interviews with a sample of three Mathematics teachers and three principals along with a focus-group interview of twelve teachers in order to investigate more deeply the perceptions of teachers and principals toward assessment policy and practice. The study shows that Grade 10 assessment practice in Namibian schools is far from ideal. Many teachers are not fully conversant with the various continuous assessment components as outlined by policy, and teachers are not confident about setting appropriate continuous assessment tasks. There is a strong perception that continuous assessment marks can easily be inflated and those teachers who gave high continuous assessment marks to their learners were generally perceived as being either incompetent or dishonest. While continuous assessment was seen as an important component of teaching and learning, it is evident that teachers and principals would welcome greater clarity, along with standardization and moderation, with respect to continuous assessment practice.

- Description: Heat Shock 40 kDa proteins (Hsp40s) partner with heat shock 70 kDa proteins (Hsp70s) in facilitating, among other chaperone activities; correct protein transport, productive protein folding and assembly within the cells; under both normal and stressful conditions. Hsp40 proteins regulate the ATPase activity of Hsp70 through interaction with the J-domain. Plasmodium falciparum Hsp70s (PfHsp70s) do not contain a Plasmodium export element (PEXEL) sequence although PfHsp70-1 and PfHsp70-3 have been located outside of the parasitophorous vacuole. Studies reveal that a type I P. falciparum (PfHsp40) chaperone (PF14_0359) stimulates the rate of ATP hydrolysis of the cytosolic PfHsp70 (PfHsp70-1) and that of human Hsp70A1A. PFE0055c is a PEXEL-bearing type II Hsp40 that is exported into the cytosol of P. falciparum-infected erythrocytes; where it potentially interacts with human Hsp70. Studies reveal that PFE0055c associates with structures found in the erythrocyte cytosol termed “J-dots” which are believed to be involved in trafficking parasite-encoded proteins through the erythrocyte cytosol. If P. falciparum exports PFE0055c into the host cytosol, it may be proposed that it interacts with human Hsp70, making it a possible drug target. The effect of PFE0055c on the ATPase activity of human Hsp70A1A has not been previously characterised. Central to this study was bioinformatic analysis and biochemical characterisation PFE0055c using an in vitro (ATPase assay) approach. Structural domains that classify PFE0055c as a type II Hsp40 were identified with similarity to two other exported type II PfHsp40s. Plasmids encoding the hexahistidine-tagged versions of PFE0055c and human Hsp70A1A were used for the expression and purification of these proteins from Escherichia coli. Purification was achieved using nickel affinity chromatography. The urea-denaturing method was used to obtain the purified PFE0055c whilst human Hsp70A1A was purified using the native method. PFE0055c could stimulate the ATPase activity of alfalfa Hsp70, although such was not the case for human Hsp70A1A in vitro.

- Description: Several disequilibrium textures are found to occur within the hanging wall and footwall of the UG2 chromitite layer of the Bushveld Complex, South Africa. These textures include plagioclase chadacrysts found included within orthopyroxene and clinopyroxene as well as the orthopyroxenes exhibiting round crystal boundaries that appear to be resorbed. Textures found within the UG2 stratigraphy such as linear boundaries and 120° triple junctions at interfaces of adjacent plagioclase or pyroxene grains also suggest that recrystallization has taken place. The presence of both disequilibrium textures and recrystallization textures would suggest that a complex emplacement history has occurred. Ideally, this would be expected to be manifested by minerals of the same type but which are texturally distinct showing different composition. However this has been found not to be the case; minerals that suggest disequilibrium textures show similar compositions to the minerals which appear to have formed in equilibrium. This is also the same for recrystallized crystals which show the same compositions as crystals that have not been recrystallized. For example tabular clinopyroxene, which has a compositional range of En 44.6 to En 50.5, is indistinguishable from clinopyroxene occuring as discontinuous rims, En 44.3-48.2, and as intergranular necking connecting primocrysts of orthopyroxene ( En 44.3-50.4). Similarly, plagioclase occurring as inclusions with An 66.3-76.0 is indistinguishable from plagioclase occurring as zoned or recrystallized interstitial grains ( An 69.0- An 77.4). Compositional variation has however, been found to be controlled to an extent by stratigraphy in that minerals show different compositions within one layer to the same minerals within another layer, consistent with an evolving magma composition. It is concluded therefore that while composition is not texturally controlled it is to an extent stratigraphy controlled and that the evidence collected within the study supports two models for the formation of chromite within the Bushveld complex. The evidence is consistent with a combination of the magma mixing model and magma injection model to account for the textures and compositional variations found within the study. The evidence may also show support for models involving late modification of minerals by magmatic fluids but not as prominently as for the models mentioned above , Microsoft� Word 2010 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: The field of our study is Francophone African Literature and this thesis explores the themes of marginality and grief both experienced by Princess Akissi in The Blind Kingdom and Princess Pokou in Queen Pokou (2004) during their rise to power in their respective kingdoms. The two novels written by Véronique Tadjo from Ivory Coast, are subjected to thematic analysis because they are both based on similar storylines - that of conflict and rivalry within kingdoms resulting in the exile of the two princesses. One of the novels is set in a pre-colonial period while the other is set in a postcolonial era. Queen Pokou, winner of the 2005 Grand Prix Littéraire d’Afrique Noire (which is the most distinguished prize in Francophone African literature), is a retelling of the founding myths of the Baoulé people of Ivory Coast. In her literary texts, Tadjo transgresses the original legend and her reconstruction of this legend is significant because it challenges the ritual sacrifice made by Princess Pokou in order to free her people and to become queen. In The Blind Kingdom (1990), Tadjo highlights the corruption and injustice of the ruling elite. Space is used to reinforce the King’s domination thus a revolution is necessary to overthrow the exploitative power structures in place. The revolution that takes place relies heavily on the participation of Karim and especially on Princess Akissi who chooses to rebel against her father, King Ato IV in order to stop injustice. This thematic analysis, supported by semiotic theory, aims to establish and demonstrate the relationship between marginality of the two princesses, in particular, and their subsequent grief. It sheds light on the reasons for their exclusion from power as well as the nature of the conflicts that occur as they rise to power. The study postulates that certain myths and images are evoked by the novelist to symbolise the exclusion of the two princesses from power.

- Description: The challenge for Namibia is to translate Vision 2030 into realistic and implementable programmes and to develop and adopt a set of interventions which will raise the quality of education. The quality of education currently on offer varies from school to school and, indeed, from class to class (Namibia. MoE, 2006, p. 1). The National Standards and Performance Indicators (ETSIP, 2006) for schools in Namibia and the Education and Training Sector Improvement Programme (ETSIP), have been developed to address the quality of education across the country, and to make provision for school managers to be trained. Organisation Development is a planned change approach which focuses on the change processes of the organisation, by opening up communication, decreasing internal destructiveness – such as win-lose conflicts – and by increasing creativity in problem solving. It is based on the values and assumptions about people and their organisations. OD promotes interdependence and interconnectedness, involvement in problem solving and decision making. OD is a process for teaching people how to solve problems, take advantage of opportunities, and learn how to do better over time. OD was introduced to Evergreen Senior Secondary School in the form of a Survey Data Feedback (SDF) where data was collected, analysed and fed back to the participants. The case study involved 20 staff members made up of the principal, two head of departments and 17 teachers. Formal and focus-group interviews, as well as observation, were used to collect data. What was derived from the data was that the OD approach was something new to the participants, and served as an eye-opener. Further, it became evident from the data that participants had high hopes that OD would bring about immediate visible changes regarding the operation of their organisation. It is essential to remind participants that OD is a long-term change process, and not a “quick fix”.

- Description: The volatility transmission in financial markets has important implications for investment decision making, portfolio diversification and overall macroeconomic stability. This paper analyses volatility transmission across four South African financial markets that is the stock, bond, money and foreign exchange markets, using daily data for the period 2000-2010. It also shows whether the volatilities in the SA financial markets present a different behaviour in bull and bear market phases. The effects of the international markets volatility to the local markets volatility was also looked at in this study. To obtain estimates of market volatility, the study experimented with various volatility models that include the GARCH, EGARCH and TARCH. To examine volatility interaction and the transmission of volatility shocks, a VAR model was estimated together with block exogeneity, impulse response and variance decomposition. The study found that there is limited volatility transmission across the SA financial markets. The study also found that the money market is the most exogenous of all markets since the other three financial markets volatility is insignificant to the money market (see impulse response results). For the bond market, volatility transmission was characterized with a decreasing trend. With regard to international markets volatility, it concluded that, the shocks in the international markets will eventually affect the movement in the local markets. The results also highlighted that, world and local markets are important in accelerating the volatility transmission in SA financial markets depending on whether they are in their bull or bear phases. In the case of South Africa, the study found that volatility transmission across markets is higher during bear market periods than bull market periods. Basing on the study results which show that the volatility transmission is limited across SA financial markets, the implication to local and international investors is that there is a greater potential for diversifying risk by investing in different South African financial markets.

- Description: Women are subject to a number of societal recommendations about what it means to be an 'ideal' woman. These recommendations take the form of social scripts, constructing an idea of ideal femininity, which women must perform in order to be socially accepted and successful. 'Emphasized femininity', a white, Western, script of femininity is dominant and has been critiqued by feminists, social theorists, and individual women for the limits that it places on women's behaviour. As a result a number of alternative scripts of femininity have arisen. These scripts can provide alternatives to restrictive understandings of female sexuality and beauty - they can serve to challenge 'appropriate' feminine behaviour and hence allow women to live more freely. Raunch femininity is a contemporary alternative that uses sexually explicit public performance, and encourages specific body and dress norms, in an attempt to challenge the norms of emphasized femininity. This thesis looks at raunch femininity, specifically its norms of sexuality and beauty, in the hopes of understanding what the effects of such a script are on women's behaviour. Theoretical understandings and explanations of women's lives are often contradicted by reports that women provide of their lived experiences. For this reason, this thesis investigates the lived experiences of women who self-identify as subscribers to this script in order to assess to what extent superficial expressions of freedom have deeper effects on women's freedom. The tension between theory and empirical reports is evident. However, in many cases, the reports of research participants reveal that the script of raunch femininity, like other scripts of feminine behaviour, has its own limits that women must abide with in order to be accepted. This thesis argues that these limits outweigh the benefits of this script. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study exammes the impact of macroeconomic and financial variables on the performance of the housing property market in South Africa using monthly data for the period January 1996 to June 2008. Orthogonalised and non-orthogonalised house price returns and real estate returns are utilised as proxies for the housing property market in separate models. Three main issues were empirically analysed in relation to the linkage between selected variables and the housing property market. The first aspect examined the relationship between selected macroeconomic and financial factors and property returns. Secondly, the study examined the influence that a unit shock to each variable has on property returns over a period of time. The third aspect focused on determining the proportion of property returns variation that results from changes in the macroeconomic and financial variables. VAR modelling was thus adopted to empirically analyse these three aspects. The results reveal that house price returns are influenced by most of the macroeconomic and financial variables used in this study. Specifically, the real effective exchange rate, interest rate spread and manufacturing production positively impact on house price returns while the domestic interest rate, the dividend yield and expected inflation have a negative effect. Furthermore, manufacturing production has a lagged effect on house price returns while the real effective exchange rate and domestic interest rate have a contemporaneous effect. Real estate returns are not influenced by most of the variables except for the domestic interest rate and dividend yield which have a negative effect.

- Description: Using theoretical insights from elsewhere, this thesis examines and explains Lesotho’s opposition. It argues that the decline of single-member constituency and the rise of Mixed Member Proportionality (MMP) has weakened the prospects for a strong opposition in Lesotho; more parties in parliament have strengthened the hold of the ruling party. These parties cannot overturn the parliamentary decisions of the ruling Lesotho Congress for Democracy (LCD), which continues to win more than 90% of majority seats in successive elections. So, most bills and motions passed in parliament have support of the majority of the MPs of LCD. Opposition parties have little legislative impact in challenging the policies of government. Paradoxically, MPs of the LCD are often the only source of opposition in the country’s parliament.

- Description: This study is a situational analysis of a school located at Nonkcampa village, just ten kilometres from King William’s Town, west of the national road between Peddie and King William’s Town. Toise Senior Secondary School is in the former Ciskei region. The Bulembu / Bisho airport is just next to our school. My focus on Toise Senior Secondary School, provides me as the principal of the school with a golden opportunity to find out more about the school. As a relative newcomer to the school this study also enables me to look at the school community, from this particular focal point. As this is a situational analysis, my focus will be on the history, the biophysical and socio-political aspects that influenced the development of the school to the present. In this way I will be able to analyse the school’s readiness to implement the new Out-Comes-Based Education (OBE) Curriculum soon to be implemented at secondary school level.

- Description: Voice training has been influenced by separatist attitudes which have allowed for classes which train the body to be separate from those which train the voice. This study acknowledges that to train an actor in separate compartments and then expect the completeness of human expression in performance, is to train under false pretences. There is a need to address the imbalance of separatism and this is examined within the context of voice training. An holistic approach to voice training forms the basis of the argument, which focuses on the need to re-educate the notion of physicality in voice training. Chapter one proposes an understanding of the notion of physicality by drawing on the attitudes of selected theatre practitioners towards the physical nature of the theatre encounter. The expressive energies of the actor's body are responsible for the physicalisation of a play; for this reason the movement of voice and speech is not only examined as source movement, but also as the movement of an actor's response and communication. Chapter two examines some practices which led to attitudes of separatism in voice training, and introduces prevalent practices which are attempting to involve the energy of the physical experience. Chapter three proposes that the Alexander technique be used as the foundation for an awareness of individual physicality. Where chapter one examines the theory of this notion, chapter three proposes an experiential understanding of the same. The Alexander technique is a training in effective body use and it's principles are fundamental to an awareness of body use and functioning. It is argued that these principles should underlie a re-education of physicality. The final chapter of the thesis argues for physicality in South African voice training programmes which would complement the physicality of contemporary theatre forms. It is hoped that this study will provide further incentive for the continued review and adjustment of drama training in South Africa.

- Description: The Mfengu, or Fingos, of the Transkei were a mixed group of refugees. Originally driven from Natal during the Mfecane, they moved into the Transkei and then the Ciskei. In the 1860's some were allowed by the Cape government to settle in an area in the Western Transkei which it had recently seized. The majority of those who moved were opposed to mission work and education. When therefore the government agent for Fingoland, Captain Blyth, and a Free Church of Scotland missionary, Richard Ross, gained the support of a few headmen for an educational Institution in the Transkei, and approached Dr James Stewart of Lovedale to found such an Institution on the lines of Lovedale, they had very slender support. Mfengu subscribe £10.00 towards the cost. Stewart agreed on condition the support for this somewhat startling and, to some, unpalatable request was gained mainly because it was known that the government intended introducing a hut tax which would be far more onerous than the levy which, it was estimated, would be required to find the sum Stewart was asking. Blyth was able to use the agreement to a voluntary levy for an institution to persuade the government to postpone the tax. The Institution was built on a larger scale than had been planned, for the Mfengu made two subscriptions, each larger than the total requested, and Stewart raised money in Scotland.

- Description: This essay is an attempt to evaluate the methods of evangelism used by John Wesley during the course of his long ministry in the eighteenth century. Wesley's methods are important, since by their use he exercised a remarkable influence upon the religious and social life of eighteenth-century England. They have a continuing importance, too, for a Church that wants to carry out her Lord's "Great Commission" effectively. In the history of the Church Wesley stands in the front rank of those who have significantly carried forward the mission of the Church. Therefore we do well to pause and learn what we can from his example and experience. Intro., p. 1.
