- Description: Student-centered learning is an increasingly popular approach that shifts the focus from the teacher to the student. The approach argues that we need to have a clear understanding of who our students are and what their needs are in order for us to provide quality education. This paper applauds the focus on the student but raises two concerns about absences in this approach. Firstly, student-centered approaches rarely consider the actual knowledge being taught and learnt. There is little consideration of how the disciplinary knowledge is constructed and what norms and values underpin such constructions. Secondly, student-centered approaches are often undertaken within the dominant autonomous discourse where student success or failure is seen to result from characteristics inherent in the student. She is understood as an individual rather than as a member of a larger social group and there is equally little acknowledgement of the socially constructed nature of universities and the practices within them.

- Description: The essentiality for waste reduction in society is prompted by the depletion of natural resources. Internationally, five waste management strategies have been identified, namely reduction of waste (waste prevention), re-use of waste, recycling of waste, recovery of energy and disposal to landfill. In Polokwane Declaration of September 2001, South Africa’s Department of Environmental Affairs and Tourism committed itself to achieve a 50 percent reduction in the volume of waste generated by 2012 and to be landfilled and have a zero waste plan implemented by 2022. Through the National Waste Management Act, No. 59 of 2008, the South African government also committed itself to provide protection of health, well-being and the environment through measures to avoid and minimise the generation of waste. Even though several policies and legislative documents are available that address waste minimisation and recycling, individual community members are however still reluctant to participate in these activities. This study therefore investigated the current levels of understanding, education and commitment to recycling and waste minimisation in a selected South African community. The target respondents of the study were members of a local church who are representative of the various peoples that reside in the communities serviced by the selected municipality. A convenience sample of 70 participants from that church was selected to complete the questionnaires. Seventy (70) questionnaires were distributed, and all 70 questionnaires were returned. Interviews were also conducted with two managers from the Waste Management Department of the selected municipality. The data analyses conducted, included descriptive statistics and content analysis of the interview transcripts. The empirical results revealed among others that: (1) recycling removal service is limited to pre-selected recyclables; (2) the municipality contributes to local entrepreneurial opportunities; (3) public participation is a pre-requisite in the success of the programmes; (4) participation is determined by convenience; (5) enforcement of legislation assists with compliance; (6) environmental sustainability is supported by environmental concerned consumers; (7) mismatch of opinions around separation at source of generation and (8) continuous education is instrumental in waste management. The main recommendations of the study include: (1) municipalities need to provide exciting and innovative recycling and waste minimisation programmes, continuously; (2) positive attitude and behaviour of all the stakeholders determines the success of waste minimisation and recycling; and (3) society, industry and government need to join forces in ensuring success in waste management. By implementing these recommendations, stakeholders in this field of interest will go a long way in improving waste management in South Africa communities.

- Description: Despite extensive research into the effects of alcohol consumption, there is no clear understanding into the mechanisms underlying human information processing impairment. The acute consumption of alcohol was investigated to determine the implications for human information processing capabilities, and to identify the extent to which these implications were stage-specific. Further aims included the investigation and quantification of caffeine-induced antagonism of alcohol impairment. Moreover, the aforementioned relationships were investigated in morning versus evening conditions. A test battery of six resource-specific tasks was utilised to measure visual perceptual, cognitive and sensory-motor performance, fashioned to return both simple and complex measures of each task. The tasks implemented were: visual perceptual performance (accommodation, visual detection, visual pattern recognition); cognition (memory recall- digit span); and motor output (modified Fitts‟ and a driving simulated line-tracking). Performance measures were recorded by the respective computer based tasks. Physiological variables measured included heart rate frequency, heart rate variability (RMSSD, High and Low Frequency Power) and body temperature. Saccade speed, saccade amplitude, pupil size and fixation duration were the oculomotor parameters measured. Three groups of participants (alcohol, caffeine+alcohol and control) n=36 were studied, split evenly between sexes in a mixed repeated/non-repeated measures design. The control group performed all test batteries under no influence. The alcohol group performed test batteries one and two sober, and three and four under the influence of a 0.4 g/kg dose of alcohol. Group caffeine+alcohol conducted test battery one sober, two under the effect of caffeine only (4 mg/kg), and three and four under the influence of both caffeine and alcohol (0.4 g/kg). The third test battery demonstrated the effects of alcohol during the inclining phase of the blood alcohol curve, and the fourth represented the declining phase. Morning experimentation occurred between 10:00 - 12: 45 and 10:30 -13:15 with evening experimentation between 19:00 - 21:30 and 19:30 - 22:00. Acute alcohol consumption at a dose of approximately 0.4 g/kg body weight effected an average peak breath alcohol concentration of 0.062 % and 0.059 % for the alcohol and caffeine+alcohol groups respectively. Task-related visual perceptual performance demonstrated significant decrements for simple reaction time, choice reaction time and error rate. Cognitive performance demonstrated no significant performance decrements, while motor performance indicated significant decrements in target accuracy only. Physiological parameters in response to alcohol consumption showed significantly decreased heart rate variability (RMSSD) in the modified Fitts‟ task only. A significant decrease in saccade amplitude in the memory task was the only change in oculomotor parameters. Prior caffeine consumption demonstrated limited antagonism to task-related alcohol impairment, significantly improving performance only in reduced error rate while reading. Caffeine consumption showed stimulating effects on physiological parameters, significantly increasing heart rate and heart rate variability when compared to alcohol alone. The design of the tasks allows for comparison between complex and simple task performance, indicating resource utilisation and depletion. Complex tasks demonstrated higher resource utilisation, however with no statistical performance differences to simple tasks. Physiological parameters showed greater change in response to alcohol consumption, than did the performance measures. Alcohol consumption imposed significant changes in physiological and oculomotor parameters for cognitive tasks only, significantly increasing heart rate frequency and decreasing heart rate variability, skin temperature and saccade amplitude. Caffeine consumption showed no antagonism of alcohol-induced performance measures. Physiological measures showed that caffeine consumption imposed stimulating effects in only the neural reflex and memory tasks, significantly increasing heart rate frequency and heart rate variability. Prior caffeine consumption significantly decreased fixation duration in the memory task only. The time of day at which alcohol was consumed demonstrated significant performance and physiological implications. Results indicated that morning consumption of alcohol imposes greater decrements in performance and larger fluctuations in physiological parameters than the decrements in evening experimental sessions. It can be concluded that alcohol consumption at a dose of 0.4 g/kg affects all stages in the information processing chain. Task performance indicates that alcohol has a greater severity on the early stages of information processing. Conversely, under the influence of alcohol an increased task complexity induces greater effects on central stage information processing. In addition, caffeine consumption at a dose of 4 mg/kg prior to alcohol does not antagonise the alcohol-induced performance decrements.

- Description: Democratic South Africa, with its highly inclusive constitution and embrace of all races, creeds and colours, could be understood as having an ideal form of citizenship to be emulated by other nations. At the heart of the 1996 constitution is the eradication of apartheid separation and the provision that all South Africans have shared humanity (‘ubuntu’). The Truth and Reconciliation Commission entrenched three founding critical ideas in public life: the right to talk, the recognition of shared humanity and the impulse to speak out about the horrors of the past. As a result the public sphere is filled with a great outpouring of personal stories and experiences in both the mainstream and popular forms of media. But South Africans continue to be preoccupied with the status of their citizenship; who a South African is and who belongs is uppermost in many public conversations.

Development of a creep sample retrieval technique and friction weld site repair procedure

- Description: The remnant life monitoring of creep loaded high temperature and pressure components in power stations is critical to ensuring their safe and cost effective operation as failures can have severe consequences. Effective creep life condition monitoring allows for optimising component life predictions and subsequent plant maintenance decisions. In South Africa many power generation stations have been in operation well beyond their 30 year design service life, as such knowledge of the remnant creep life of high temperature and pressure components, such as steam pipelines, becomes of utmost importance. Techniques for the remnant creep life assessments of critical high temperature and pressure components must therefore be as effective as possible. The common and well accepted in-situ inspection technique for assessing creep damage in steam pipes is by the metallographic replication technique. The technique is however limited to the outer surface of the pipe, without information on damage within the wall. This research will illustrate a means of obtaining a sample for creep life analysis with depth through the wall of a pipe, as wells as an alternative technique for the repair of the sample retrieval site. A sample retrieval technique was developed that would retrieve a small diameter cylindrical sample from a cored blind hole for creep analysis by visual creep void assessment or by the small punch creep test. The small punch creep test requires only a small diameter thin disc of material for testing for which its results are comparable with conventional uniaxial creep testing which requires a much larger sample of material. The smaller sample requirement of the small punch creep test therefore allows for a vastly reduced invasive sample retrieval operation and consequently smaller repair size area. Also the fact that the sample is retrieved from a blind hole is advantageous since the pipe wall is not penetrated which would require full plant shutdown. A friction welding technique was identified as an alternative to traditional arc fusion welding for the repair of the sample retrieval site, this technique being the Friction Hydro Pillar Processing technique. Friction Hydro Pillar Processing is a solid-state welding technique and as such has a number of inherent benefits over arc fusion welding as the weld is performed below the melting temperature of the material. From a process point of view Friction Hydro Pillar Processing is ideally suited for automation, has virtually no fumes generated, minimal distortion is experienced and no spatter has to be removed afterwards. The technique has yet to see industrial application and as such development of suitable process parameters was undertaken. Finally, to apply the sample retrieval and repair operations in-situ to a steam pipe in a power plant suitable equipment was developed. Existing friction welding equipment is generally bulky workshop based equipment and is unsuitable for on-site work due to its size and weight. Therefore development of dedicated equipment was required to enable Friction Hydro Pillar Processing to be applied to steam pipes within a power plant environment.

- Description: The work described in this study aims to investigate methods that will improve a lengthy synthetic pathway in the synthesis of the P57 cymarose moiety, and to examine the conformational structure of certain glycosides in order to shed light on the problematic stereochemical issues surrounding the formation of the cymarose glycosyl donor. The cymarose moiety forms part of the trisaccharide derivative present in P57, an appetite suppressant molecule. Modification of reaction steps in the conversion of the stereochemistry at C-3 of a previously reported synthesis of the P57 cymarose moiety was carried out. The first step was the selective oxidation of D-glucal using Pd/C in the presence of acetonitrile. These reaction conditions are more appropriate for the oxidation step to avoid decomposition of the formed molecules. Successive protection of the free OH groups was followed by NaBH4 reduction under stereo-controlled conditions, influenced by CeCl3•7H2O. However, the reduced product could not be isolated from the starting material and this led to ambiguous results when attempting to confirm whether the conversion of the stereochemistry at C-3 had occurred or not. The effect of reaction conditions, such as change in reaction temperature, during the preparation of the cymarose glycosyl donor was studied in order to find suitable reaction conditions to produce α,β-allo derivatives with high stereoselectivity. Compared to the reported synthetic method, this set-up gave improved yields with, unfortunately, similar or slightly lower selectivity to the formation of α-altro:α,β-allo derivative. Examination of the conformational structure of the allal derivative, in order to understand the mechanism at work during the placement of the directing group at C-2, was carried out using molecular modelling. The mechanistic implications of this very short study are discussed and it provides some insights into the likely pathway of the iodination reaction and its selectivity in particular, to the D-allose system.

In different countries the work has appeared under different titles—Exhibit A and Exhibit B, while Exhibit C will be produced in 2014. These productions replicate and parody ethnographic spectacles of the nineteenth century, interrogating European colonial atrocities in Africa, as well as contemporary xenophobia. They consist of a series of installations housed in individual rooms that audience members enter one by one. Inside these rooms one is confronted by beautifully arranged spectacles referencing historical atrocities committed in Namibia by German speaking peoples, as well as atrocities under the Belgian and French colonial regimes in the two Congos. The “exhibits” also include references to more recent incidents of European racism against migrants from Africa. The work has been both applauded and derided. In Berlin, for example, activists called it “a human zoo” and protested that this was “the wrong way to discuss a violent colonial history,”1 while others have called the work “haunting”, praising the production for its “dignity” and “beauty.”2

- Description: This research investigates three solutions to overcoming portability and scalability concerns in the Evolutionary Hardware (EHW) field. Firstly, the study explores if the V-FPGA—a new, portable Virtual-Reconfigurable-Circuit architecture—is a practical and viable evolution platform. Secondly, the research looks into two possible ways of making EHW systems more scalable: by optimising the system’s genetic algorithm; and by decomposing the solution circuit into smaller, evolvable sub-circuits or modules. GA optimisation is done is by: omitting a canonical GA’s crossover operator (i.e. by using an algorithm); applying evolution constraints; and optimising the fitness function. The circuit decomposition is done in order to demonstrate modular evolution. Three two-bit multiplier circuits and two sub-circuits of a simple, but real-world control circuit are evolved. The results show that the evolved multiplier circuits, when compared to a conventional multiplier, are either equal or more efficient. All the evolved circuits improve two of the four critical paths, and all are unique. Thus, it is experimentally shown that the V-FPGA is a viable hardware-platform on which hardware evolution can be implemented; and how hardware evolution is able to synthesise novel, optimised versions of conventional circuits. By comparing the and canonical GAs, the results verify that optimised GAs can find solutions quicker, and with fewer attempts. Part of the optimisation also includes a comprehensive critical-path analysis, where the findings show that the identification of dependent critical paths is vital in enhancing a GA’s efficiency. Finally, by demonstrating the modular evolution of a finite-state machine’s control circuit, it is found that although the control circuit as a whole makes use of more than double the available hardware resources on the V-FPGA and is therefore not evolvable, the evolution of each state’s sub-circuit is possible. Thus, modular evolution is shown to be a successful tool when dealing with scalability.

- Description: This research investigates three solutions to overcoming portability and scalability concerns in the Evolutionary Hardware (EHW) field. Firstly, the study explores if the V-FPGA—a new, portable Virtual-Reconfigurable-Circuit architecture—is a practical and viable evolution platform.

- Description: This study provides a description and critical analysis of the grammatical structure of isiXhosa as used in the Revised Union Version of the Bible, published in 1942 and republished in 1975. This translation records what was regarded as proper isiXhosa at the beginning of the 20th century, reflecting the consensus inter alia of prominent isiXhosa writers, such as W.B. Rubusana, J.H. Soga, C. Koti, Y. Mbali and D. D. T. Jabavu, who served on the committee that produced the revision. In this study isiXhosa is described in its own right, without approaching it with preconceived ideas derived from other languages. That is to say this is a phenomenological analysis describing the grammatical structures of isiXhosa as they present themselves to the analyst. It is comprehensive, with no structure being overlooked or being described in such a manner that it complicates an understanding of other structures. In the first chapter the context of the research and a brief outline of the historical growth in understanding the structure of isiXhosa are set out and the goals and the method followed in this study are described. In the following chapters the findings of this study are presented. The initial focus is on isiXhosa phonology and the orthography used to put it to writing. Then isiXhosa morphology and syntax is set out. Initially the substantives, i.e. the nouns and pronouns in their distinctive classes and forms, and how they are qualified, receive attention. Then the predicates are explored, i.e. the verbs and copulatives, as linked to the substantives with concords, and reflecting various moods, tenses, actualities and aspects. Finally attention is given to ideophones and interjections and words that can be grouped together as adverbs, conjunctions, avoidance words and numerals. In the concluding chapter consideration is given to the question of whether this study has in fact achieved the aim of setting out a description of the structure of isiXhosa based solely on the language itself, free of preconceived ideas, and attention is drawn to insights gained in respect of the true nature of the isiXhosa grammatical structures, such as, for example, the variable prefix qualificative nouns, traditionally referred to as adjectives. This study is therefore a revisionist study in the sense that it reinvents isiXhosa as a language in its own right, free from Western influenced perspectives.

A critical analysis of the deductibility of audit fees

- Description: The strict and narrow scope of the general deduction formula may result in taxpayers being denied deductions for business expenditure, which are clearly and legitimately incurred in the course of operating their businesses, which in turn will result in an increase in tax costs, an important component of business costs. Although audit fees often fail the deductibility test, in general they are regarded by taxpayers as automatically deductible despite the fact that such fees were not incurred in the production of income. The deductibility of audit fees reached the High Court recently for the first time in the MTN case. It was argued by the South African Revenue Service (SARS) in this case that audit fees should never been allowed as a deduction because the role of an auditor does not relate to the production of income and that an auditor’s duty is restricted to verification of financial information ex post facto for the benefit of investors, creditors and other users of the financial information. The Court held that statutory audit fees should be deductible relying on the basis of the time spent during the audit in verifying deductible and non-deductible income. It is concluded by the author that law which creates uncertainty needs to be updated in keeping with the Government’s intention of creating a business environment in order to promote commerce and entrepreneurship. It is therefore proposed that all audit fees relating to statutory audits should be declared as a specific statutory deduction to ensure legal certainty.

- Description: There is a consensus globally that climate change is one of the biggest challenges facing operations. Immediate actions are required to reduce the carbon footprint in order for the environment to endure future logistics processes and activities (The National Treasury department of South Africa, 2010). Greenhouse gases (GHGs) are emissions generated from manufacturing processes, distribution networks and treatments processes (Verfaillie and Bidwell, 2000). Companies globally are expected to monitor pollution and focus on reducing the discharge of pollutants. Logistics Managers are therefore pressured to reduce the carbon footprint as it affects the environment and our health. Companies are becoming more concerned with the impact of various activities and processes on the environment. Traditional logistics models, primarily focuses on minimising cost with little focus on the environmental impact and sustaining operations for the future (Sbihi and Eglese, 2009) General Motors (GM) is a multi-national vehicle manufacturer with operations in various countries. GM filed for bankruptcy in 2009 resulting in the formation of the new GM; one of the focus areas was to ensure sustainability which resulted in the introduction of the ‘Sustainability in motion’ program in 2009 (New York Times, 2009). General Motors South Africa (GMSAf) is a vehicle assembler with manufacturing facilities and head offices located in Port Elizabeth. The company is a wholly owned subsidiary of the multinational General Motors Company. The aim of the research is to determine whether a culture that promotes environmentally conscious behaviour exists within employees and their relationships within a team, with management, stakeholders and suppliers. The study will assist in highlighting areas which need improvement to enable the creation of environmentally sustainable initiatives and implementation thereof. The empirical study revealed that the following management commitment, education and training, performance management and participation and involvement were important factors in the effective implementation of an environmental sustainability program.

- Description: Understanding customers’ views on service quality is important for any business providing service and interested in making sure that they are being responsive to customers. Continuous evaluation of customer satisfaction is an important factor in the service sector. To date, most attempts have focused on what determines customer satisfaction in services rendered by organisations. The primary objective of the current study was to identify the determinants of customer satisfaction with services at Government Employees Pension Fund. The study investigated how customer satisfaction (the dependent variable) is influenced by the different elements, namely service quality, perceived value, and customer expectations, which represented the independent variables. The significance of the study hinges on three area i.e. management, policy makers and stakeholders. The study will also provide a justifiably valid and reliable guide to designing workable service delivery improvement strategies for creating and delivering customer value, achieving customer satisfaction and achieving sustainable business growth of Government Employees Pension Fund. The data collection was made using the questionnaire. A total of 150 questionnaires was distributed and 108 were completed and returned. This translated to a response rate of 72 percent. The empirical results showed that service quality and perceived value have a positive impact on customer satisfaction. On the other hand, the results revealed that customer expectations do not have a positive influence on customer satisfaction.

- Description: This thesis provides a detailed consideration of the family in Shakespeare’s canon and the engagement therewith in three South African novels: Hill of Fools (1976) by R. L. Peteni, My Son’s Story (1990) by Nadine Gordimer, and Disgrace (1999) by J. M. Coetzee. The study is divided into an introduction, three chapters each addressing one of the South African novels and its relationship with a Shakespeare text or texts, and a conclusion. The introductory chapter provides an analysis of the two strands of criticism in which the thesis is situated – studies of the family in Shakespeare and studies of appropriations of Shakespeare – and discusses the ways in which these two strands may be combined through a detailed discussion of the presence of power dynamics in the relationship between parent and child in all of the texts considered. The three chapters each contextualise the South African text and provide detailed discussions of the family dynamics within the relevant texts, with particular reference to questions of authority and autonomy. The focus in each chapter is determined by the nature of the intertextual relationship between the South African novel and the Shakespearean text being discussed. Thus, the first chapter, “The Dissolution of Familial Structures in Hill of Fools” considers power dynamics in the family as an inherent part of the Romeo and Juliet genre, of which William Shakespeare’s Romeo and Juliet is but a part. Similarly, the impact of a socio-political identity, and the secrecy it necessitates, is the focus of the second chapter, “Fathers, Sons and Legacy in My Son’s Story” as is the role of Shakespeare and literature within South Africa. These concerns are connected to the novel’s use of Shakespeare’s Sonnets, King Lear, and Hamlet. In the third chapter, “Reclaiming Agency through the Daughter in Disgrace and The Tempest”, I expand on Laurence Wright’s argument that Disgrace is an engagement with The Tempest and consider ways in which the altered power dynamic between father and daughter results in the reconciliation of the father figure with society. The thesis thus addresses the tension between parental bonds and parental bondage

- Description: The main focus of this study is the challenges of rural tourism development in Zimbabwe. The study identified that there is a lack of sustainable interventions in the development of rural tourism which is catalyzed by the absence of rural tourism promotion strategy to support the sustenance of livelihoods through socio-economic transformation. Meaningful socio economic transformation in the African rural areas through tourism remains a major development challenge. Development initiatives through different forms of tourism in the rural communities, has to a less magnitude benefited the rural communities and have negatively impacted the socio–economic environment. A qualitative research methodology and case study design was employed in order to have a deeper understanding of the experiences of the society around this project. Face to face interviews and focus group discussions guides were used to collect primary data. Purposive and convenience sampling techniques was employed to select respondents. Data was analysed using the transformative theory and sustainable livelihoods theory and was organized into categories and themes. The study established that the absence of a strategy is caused by political instability, community conflict, lack of finance, marketing, poor communication, and limited knowledge of tourism. All the aforementioned reasons complement each other and poise a challenge to the sustainability of rural tourism development. For Zimbabwe to effectively transform its economy through tourism, the government needs to plan the process, formulate and implement relevant economic and social development strategies and policies. Although this dissertation is a case study of sustainable rural tourism in Zimbabwe, it can be used to appreciate the role of tourism in bringing about socio-economic transformation and sustaining livelihoods in developing countries.

- Description: This interpretive exploratory case study investigated the challenges and barriers to the multi-grade context in general, as well as to Information and Communication Technology (ICT) implementation in a multi-grade context. Possible solutions based on teacher perceptions were generated inductively within a three-level typology. The research took place in three phases. Pre-training data were gathered in the first phase, using an open-ended questionnaire (all participants: n=20); personal interviews (n=9); and two focus group interviews, which consisted of three participants per focus group. Training on the Intel® Teach ICT programme and the provision of laptops (one per teacher) constituted the second phase. The third phase included post-training data generation using an open-ended questionnaire (all participants) and two focus group interviews, which consisted of three participants per focus group, to elicit teacher perceptions of the training programme and their use of the laptops in the classroom after the training. The findings suggest that first order (school or meso level) challenges pertaining to multi-grade teaching relate to the lack of resources; curriculum challenges; learner related challenges; isolation, impact on communication and teaching; time constraints; and a work overload as a result of the multiple roles. Second order challenges (self or micro level) related to the perceived uncaring attitude of the Department of Basic Education that left teachers feeling hurt and neglected; the unpreparedness for the multi-grade context which demotivated teachers; and the negative perceptions the teachers had about their learners. Third order challenges (system level, beyond the school level or micro level) were related to the lack of Departmental support from officials; the lack of curriculum training for the multi-grade context; and the lack of support on various fronts. Regarding ICT related challenges, the findings suggest that first order barriers related to the lack of suitable infrastructure for ICT implementation; lack of peer support; lack of access to appropriate hardware and software; and lack of time. Second order barriers related to the negative beliefs in the self; negative perceptions about the learners’ ability to use the laptop; and negative beliefs related to teaching and learning. The third order barriers were related to the lack of support and assistance from the Department of Basic Education for ICT implementation. The findings suggest that the participants viewed the provisioning of enabling programmes for parents as an important solution to first order challenges, and a change in mindset as the most important solution for second order problems. Third order solutions included a “multi-grade Renaissance” towards a new model for multi-grade teaching; re-thinking the curriculum requirements regarding multi-grade teaching by the Department of Basic Education; increased support and training from the Department; incentives to teach with ICT in the multi-grade context; encouraging further research inmulti-grade teaching; providing sufficient resources; establishing partnerships with stakeholders; and the closure and merger of multi-grade schools. There was evidence that the laptops provided were used in a variety of ways after the Intel® Teach training by the participants, including email as a tool to communicate with their fellow multi-grade peers, which serve to break their sense of isolation. Quantitative data from the open-ended questionnaire confirmed an increase in the usage of the laptop after the Intel® Teach training intervention. Although the participants generally experienced the Intel teach training intervention as positive, they also identified negative experiences. These findings enabled the embedding of ‘self and sustainable support from stakeholders’ more explicitly in the professional teacher development ICT implementation framework of Du Plessis and Webb (2012b), which suggests that the Intel® Teach training intervention can be used as a vehicle to address ICT implementation within the multi-grade context. It is suggested that the Department of Basic Education should consider exposing all teachers to the Intel® Teach programme and assist multi-grade teachers by providing better on-going support and putting the necessary policies, implementation and infrastructure in place.

- Description: This interpretive exploratory case study investigated the challenges and barriers to the multi-grade context in general, as well as to Information and Communication Technology (ICT) implementation in a multi-grade context. Possible solutions based on teacher perceptions were generated inductively within a three-level typology. The research took place in three phases. Pre-training data were gathered in the first phase, using an open-ended questionnaire (all participants: n=20); personal interviews (n=9); and two focus group interviews, which consisted of three participants per focus group. Training on the Intel® Teach ICT programme and the provision of laptops (one per teacher) constituted the second phase. The third phase included post-training data generation using an open-ended questionnaire (all participants) and two focus group interviews, which consisted of three participants per focus group, to elicit teacher perceptions of the training programme and their use of the laptops in the classroom after the training. The findings suggest that first order (school or meso level) challenges pertaining to multi-grade teaching relate to the lack of resources; curriculum challenges; learner related challenges; isolation, impact on communication and teaching; time constraints; and a work overload as a result of the multiple roles. Second order challenges (self or micro level) related to the perceived uncaring attitude of the Department of Basic Education that left teachers feeling hurt and neglected; the unpreparedness for the multi-grade context which demotivated teachers; and the negative perceptions the teachers had about their learners. Third order challenges (system level, beyond the school level or micro level) were related to the lack of Departmental support from officials; the lack of curriculum training for the multi-grade context; and the lack of support on various fronts. Regarding ICT related challenges, the findings suggest that first order barriers related to the lack of suitable infrastructure for ICT implementation; lack of peer support; lack of access to appropriate hardware and software; and lack of time.

- Description: Information and Communication Technology (ICT) has taken over every aspect of our daily lives, from commerce to leisure and even culture. Today, mobile phones, desktop computers, hand-held devices, emails and the use of the internet have become a central part of our culture and society. ICT has made us a global society, where people can interact and communicate efficiently. In order for South Africa to be competitive in the global economy, it will need to develop a workforce with appropriate Information Technology skills. Of necessity, these skills will extend to using a computers and developing appropriate software and technical support skills (DOE, 2008). This thesis represents a critical analytical study in that it explores the online Sesotho Information and Communication Technology (ICT). It aims at analysing terminology development in this area. The study aims to determine how Sesotho and ICT correlate and how the linguistic aspect plays a role in online ICT terminology. The focus is not on creating new terms but to analyze the already existing ICT terms available, with regards to linguistic rules and principles and to critique if they are of quality. Furthermore, the thesis explores whether there are other strategies that can be used in the development of this terminology. It also seeks to determine if the terms are easily accessible to students and if they are used at all. Terms will be sourced from the Department of Arts and Culture ICT term list, and the focus will be on extracting only terms that have to do with computer literacy. Other online sources that list Sesotho equivalents will also be considered. The study also assesses the quality of the terms created by the Department of Arts and Culture (DAC) together with the Department of Communications (DOC) for a multilingual ICT terminology list. Furthermore, the thesis explores whether the Sesotho equivalents adhere to the linguistic rules and principles of the language. The other question asked is whether the terms are used by the intended users and if they are easily accessible to the speakers of the language. This entire aspect of the thesis speaks to the notion of the intellectualization of African languages and in this case Sesotho in particular. Not only does the thesis engage with computer literacy terminology, it also presents a detailed literature review of studies and work that has been done in this field. The thesis engagement is also done by linking the backdrop of the history of Sesotho and the Basotho peoples.

- Description: In 1962 John moved south to Johannesburg, but that bustling city held few attractions for him and he moved further south, to the cathedral city of Grahamstown. Grahamstown, with its nineteenth century Gothic cathedral, elegant Georgian buildings, and distinctive grandeur of Rhodes University, St Andrew's College and other buildings designed by Herbert Baker and his colleagues, suited John. He particularly enjoyed the academic, social, artistic and dramatic life of the community, where many older members of society were distinguished old-Africa hands. John thoroughly enjoyed Grahamstown where, in the partnership of Hoskins and English, he made his mark in the restoration and extension of many significant buildings. His addition to the Anglican chapel at Hog's Back is a masterpiece, as is his incorporation of the old fayade into the rebuilding and extension of the Magistrates' Court.

- Description: What ought beneficiaries of injustice to do with the privileges unjustly conferred upon them? This article examines how those who have been privileged as a consequence of injustice can best contribute to struggles for justice. In particular, I ask whether we ought to renounce privileges which have been unjustly conferred, or whether it may be better to use such privileges in ways that help bring about justice. The article engages in particular with feminist literature on the topic of privilege, building on arguments provided in this literature to argue that in many cases the best contribution the privileged can make to struggles for justice, is to use unjustly conferred privileges in a way that ultimately undermines the unjust systems and structures that conferred them. I tentatively outline some ways in which the privileged can develop the sensibilities which will allow them to use their privilege in this way.

- Description: The present study investigates the use of English and isiXhosa in teaching and learning Physical Sciences in four King Williams Town schools. Physical Sciences educators and Grade 11 Physical Sciences learners were interviewed to find out about their perceptions with regard to the language(s) used in the learning and teaching of the subject Physical Sciences. The same educators and learners were also observed to find out their actual language practices in class. The findings revealed that English was the preferred medium of instruction in the learning and teaching of Physical Sciences, even though the majority of learners had low proficiency in English. Both teachers and learners extensively use code-switching to bridge this language gap in order to improve the learning of content. The choice to use isiXhosa to bridge the English second language barrier was influenced by the language profile of the learners. However, even in lessons in which teachers used code-switching, the participation of learners in class discussions was very low because the delivery of the lessons was still teacher-centred. The National Department of Education assessment policy seems to limit schools toward adopting English as the LoLT even though learners in these schools were isiXhosa first language speakers. The fact that all assessment are done in English leads to school adopting English on LoLT. Schools adopted the English only policy as way of promoting learners’ learning and understanding of English, so that the learners are not disadvantaged by the English language factor when writing examinations.
