- Description: β-methylamino-L-alanine (BMAA) is thought to be a contributing factor of Amyotrophic Lateral Sclerosis-Parkinsonism Dementia Complex (ALS/PDC). It has been shown that the levels of toxin ingestion by humans are too low to cause disease. However, it has recently been theorized that this toxin is bioaccumulated within cells. Via a process of slow release from this reservoir, the BMAA is able to bring about neurotoxicity. Mechanisms of uptake and bioaccumulation of BMAA have been proposed in several publications; however the mechanism of protein incorporation of BMAA has not yet been identified. Identifying suitable model systems would be a prerequisite in order for future studies on BMAA protein incorporation. Three specific models were therefore chosen for investigation; mammalian cell lines including C2C12 and HT29, a prokaryotic (E. coli) expression system and yeast cells. The cytotoxity of BMAA was established for the mammalian cell lines and further investigation of BMAA incorporation into cellular proteins was performed on all three above mentioned models. Samples were run on HPLC-MS in order to determine uptake of BMAA into cells or lack thereof. Results indicate negligible cytotoxicity as measured by MTT and CellTitre Blue assays, limited uptake and protein incorporation of BMAA within the prokaryotic model and insignificant uptake of BMAA by yeast cells. Although the uptake of BMAA in the prokaryotic model was not extensive, there was indeed uptake. BMAA was not only taken up into the cells but was also observed in inclusion body protein samples after hydrolysis. After further investigation and use, this model could very well provide researchers with information pertaining to the mechanism of association of BMAA with proteins. Although the other models provided negative results, this research was valuable in the sense that one can narrow down the number of possible model systems available. Also, in seeking models for studying protein association/incorporation, the use of the final target cell is not relevant or necessary as the purpose of the research was to identify a model system in which the mechanism of protein association/incorporation can, in future, be studied.

- Description: The commercialization of hospitality established arguably the oldest profession. Historically small commercial hospitality establishments, known as inns in the western world, were of ill repute. Perhaps connected to their reputation, this category of accommodation facility has been seriously neglected as an area of academic inquiry, particularly from the perspective of the host. While there has been a huge growth in the interdisciplinary field of tourism studies in recent decades, little attention has been paid to the role of the host in the host-guest relationship at whatever level of analysis. This thesis seeks to redress the balance. Hospitality is a basic form of social bonding. This type of bonding, where a hierarchy between strangers is implicit (as with hosts and guests), may be termed ‘nexilitas’; nexilitas is a form of social bonding in liminal circumstances. To that extent it is comparable to ‘communitas’ which describes social bonding between equals in certain liminal circumstances. The difference is that nexilitas is a form of bonding between individuals in a complex power relationship. The host controls the hospitality space, but custom also empowers the guest with certain expectations, especially in the commercial context. The thesis identifies the various forms of hospitality – traditional ‘true’ or ‘pure’ hospitality, social hospitality, cultural hospitality and commercial hospitality – and discusses these critically in their historical and cross-cultural contexts, with emphasis on the perspective of the host. The passage of hospitality is then traced through the three phases of preliminality, liminality and post-liminality and discussed along the themes anticipation, arrival and accommodation and finally departure of the guest. While the historical and ethnographic review is mainly based on written histories and the experiences of other anthropologists as guests as well as ethnographers, the passage of hospitality draws on the multi-sited auto-anthropological experiences of the author, both as host and as ethnographer of contemporary South African hosts in small owner-managed commercial hospitality establishments.

- Description: Tourism has social and economic benefits. Economic benefits are received through tourists visiting tourist attractions. Social benefits related to benefits tourists receive personally when visiting tourist attractions. The number of individuals that are obese are constantly increasing and leads to hazardous medical conditions. The aim of this research study was to determine the extent to which geocaching can be used to increase tourism and decrease obesity. Geocaching is similar to a treasure hunt where participant use clues and a Global Positioning System device to find a treasure that are called a cache. The cache is filled with trinkets that are exchanged by participants that find the cache. Students of the second avenue campus of the Nelson Mandela Metropolitan University were used as respondents and given information on what geocaching involve. Three geocaches were hidden in The Boardwalk Casino and Entertainment World in Summerstrand, Port Elizabeth. The respondents met at The Boardwalk Casino and Entertainment World where a clue and map was provided. After finding the cache the respondents was asked to complete an anonymous questionnaire. The results were calculated and conclusions and recommendations were made. The primary research process was conducted over too short a period of time to conclude whether it can lead to a reduction in obesity. However geocaching experience by respondents did show that the process of geocaching involves physical exercise, which is needed for losing weight. Research also indicated that respondents would like to geocache with family and friends. Geocaching with family and friends involves support which secondary research have also proven is important to losing weight and decreasing obesity. Respondents indicated that they enjoyed geocaching and would like to geocache in their free time. The indication of enjoying geocaching, participating in geocaching during free time allows travelling for leisure purposes as to geocache travelling is necessary and the majority of geocaches is hidden at tourist attractions. The combination of travelling to tourist attractions, enjoying the experience and partaking in physical exercise with family and friends involve two of the three main aspects seen as helping to reduce obesity: enjoyable physical activity and support from family and friends. The conclusion is therefore that geocaching can be utilised to increase tourism and reduce obesity.

- Description: The purpose of this article was to investigate the feasibility of incorporating didanosine (DDI) into nanostructured lipid carriers (NLC) for potential treatment of AIDS dementia complex. Aqueous DDI-free and DDI-loaded NLC were manufactured using hot high-pressure homogenization. The lipid matrix contained a mixture of Precirol ® ATO 5 and Transcutol ® HP. Photon correlation spectroscopy revealed that the mean particle size for all formulations was below 250 nm with narrow polydispersity indices. In addition, the d99% values for all formulations determined using laser diffractometry were below 400 nm with the span values ranging from 0.84 to 1.0. The zeta potential values ranged from −18.4 to −11.4 mV and the encapsulation efficiency of NLC for DDI ranged from 33.02% to 78.34%. These parameters remained relatively constant for all formulations tested following storage for 2 months at 25°C indicating that all the formulations were relatively stable. Differential scanning calorimetry revealed a decrease in the degree of crystallinity of NLC in all formulations developed relative to the bulk lipid material. In addition, wide-angle X-ray scattering showed that NLC in all formulations tested existed in a single β-modification form and that DDI that had been incorporated into the NLC appeared to be molecularly dispersed in the lipid matrices. Images of the NLC formulations obtained using transmission electron microscopy revealed that all formulations contained a mixture of spherical and nonspherical particles irrespective of the amount of DDI that was added during the manufacture of the formulations.

A comparative analysis of the development of performers' rights in the United Kingdom and South Africa

- Description: Although performers have been rife for centuries, no legal regime was required for their protection owing to the fact that the nature of their performances was transitory. It was not until the invention of the phonogram in 1877, that the need to provide performers with the means to protect the unauthorised uses of their performances became an issue. The subsequent development of performers' rights has been fuelled by the rapid technological developments of the modern age which has prompted the international community to respond through various international instruments. Performers initially sought protection in terms of the Berne Convention in 1886, but it was not until the Rome Convention in 1961 that performers were first accorded international recognition. This was followed by the TRIPs Agreement in 1994 and the WPPT in 1996. This work involves an investigation into the historical development of performers' rights in the United Kingdom and South Africa. This is followed by a comparative analysis of the current state of performers' rights as between the United Kingdom and South Africa with a view to proposing recommendations for improving the level of protection accorded performers in South Africa. Arguments in favour of a regime of performers' rights as well as possible counter-arguments have been advanced. The general development of performers' rights as a related or neighbouring right to copyright is focussed on. The development of performers' rights in the United Kingdom is discussed with reference to the first English legislative form of protection, namely the Dramatic and Musical Performers' Protection Act, 1925. This Act only provided performers with criminal remedies, a view that prevailed through several subsequent enactments designed to protect performers as a result of ratification of the Rome Convention. It was not until 1988 when the decision in Rickless v United Artists Corp prompted the legislature to grant performers with enforceable civil remedies through the enactment of the Copyright, Designs and Patents Act, 1988. Several European Union Council Directives aimed at harmonising the law relating to performers' rights throughout the Union were issued, mainly in response to the TRIPS Agreement. In order to comply with these Directives, the United Kingdom passed Regulations to bring about the necessary amendments to the Copyright, Designs and Patents Act. Performers in the United Kingdom were granted moral rights in 2006 as a result of the United Kingdom's ratification of the WPPT. The development of performers' rights in South Africa has been slow when compared to that of the United Kingdom. It was not until 1967 that performers were first legally recognised in South Africa. Although South Africa has yet to ratify the Rome Convention, it was stated in South African Broadcasting Corporation v Pollecutt that the Act was clearly passed with a view to complying with the Convention. South Africa's ratification of the TRIPs Agreement brought about amendments to the Act, particularly regarding the duration of protection which was increased from 20 to 50 years. Although South Africa played an active role in the conclusion of the WPPT, it has yet to ratify it. However, amendments were made to the Act in line with this Treaty, such as the incorporation of “expressions of folklore” within the ambit of protection, and the granting of a right to receive royalties whenever a performer's performances are broadcast. This is commonly known as needletime. South Africa's reluctance to grant performers with moral rights as provided for by the Treaty is noteworthy. The introduction of needletime into South African law has resulted in a fierce debate between collecting societies (who represent authors and performers) and the NAB (who represent users of performances). Mainly as a result of this dispute, performers in South Africa have, to date, not received any royalties due to them. The protection of traditional knowledge has also received attention of late with the Intellectual Property Laws Amendment Bill, 2010 which aims to bring traditional knowledge inter alia within the ambit of the Performers' Protection Act. The current state of performers' rights in the United Kingdom and South Africa are compared in order to identify ways in which the level of protection accorded performers in South Africa could be improved. The Copyright, Designs and Patents Act is compared with the Performers' Protection Act through emphasis being placed on the definition of a “performer”; the definition of a “performance”; the nature of performers' rights; exceptions to infringement; the term of protection; the retrospectivity of the legislation; and the enforcement measures in place. Upon analysis, it was found that the Performers' Protection Act can be amended in several ways in order to increase the level of protection accorded performers in South Africa.

- Description: Black Economic Empowerment is an ideology and policy that was effected so as to streamline the inequalities that were and have been left to stand after the apartheid era in South Africa. Despite the mixed reactions that would surface as a result of the underpinnings of the policy, the main focus of the policy was and still is to provide for equality and build better business among the economic minority who in this case are the “black” people of South Africa. This report focuses on the policy and the different guidelines that have been set in place to counter the inequalities in businesses and economy with focus being on SMMEs and looking at ways in which various sections, especially the score card, with regard to exemptions to small businesses, how this aids them in achieving BEE compliance. The research accomplished this by looking at the requirements of the score card, focusing mainly on the stipulations placed on SMMEs and by the use of literary reports gathered information that would show whether the exemptions give the said enterprises added competitive advantage. The research produced a couple of findings; that although theoretically the necessity of boosting economic growth and business of one of the most productive enterprise sectors in an economy and the fact that the score card has focused infinitely on the need for SMMEs not to be fully focused on a specific cluster of criterion in the score card but more on which criterion would work best for them and which ones are easy to maneuver around to ensure maximum growth and contribution, there is the loop hole that is experienced of how this criterion is met and passed with disregard to actualization of the need to adhere to the strictness of the rules of how compliance is attained. There was also the main issue of fronting which is the falsification of ownership of a company by providing misleading information about the directors and owners of the business. The main conclusions drawn from this research are that it is important not to lose the foresight that the policy is meant to enhance and grow the economic ability of a sector and build business through which the policy makes very heavy recommendations but there are shortfalls experienced with regard to how compliance is approached putting into consideration that SMMEs have been given exemptions in the number of pillars of the score card they can apply to their business. It is also important to note that the influence and bulldozing that is expected when it comes to dealing with policies of this nature is not to be sidelined. This research aims to look at the discrepancies that are set out within the structures that hold the policy together so as to attain maximum results.

- Description: Stewardship in South Africa, as it is being implemented within the framework of the Biodiversity Stewardship Programme (BSP), is an attempt by conservation agencies to engage landowners in the voluntary securing of parcels of biodiverse land, through signing a contract for a certain time period, not to develop the landscape in ways that will impact negatively on the biodiversity of the area in question. The focus of this study is the relationship between biodiversity stewardship and social learning, as I hope to ascertain how stewardship practices are helping to resolve the current problems of biodiversity loss in the Western Cape. The overall aim of this research is to gain an understanding of how, in its capacity as a conservation education process, the Cape Nature Stewardship Programme can foster social learning amongst the landowners involved in its implementation, by leading them to a better understanding of their environmental responsibilities. Data was generated through the use of interviews and informal discussions with participants together with document analysis, such as brochures, pamphlets and presentations. My approach to the analysis of my data was two-phased. In the first phase, I analysed the data generated from the interview process and from reviewing the documents the stewardship officials supplied me with. The second phase involved looking into the results of the two case studies, and formulating analytical statements which were then used to review the case evidence within a social learning perspective, derived from Wals (2007). In constructing an analytical framework for the interpretation of my data, I drew heavily on Wals' (2007) notion of social learning occurring in sequential activities. I used this insight as a lens through which to trace the educational effects of the implementation of the CNSP in the two case study areas.The research highlighted evidence that Stewardship initiatives should be based on the foundation of social learning and invest time and effort in building an environmental knowledge capital amongst the landowners involved. By equipping them with these necessary conservation skills, one creates a 'community of practice' where those individuals adopt a sustainability habitus contributing towards a change and environmental understanding and practises in field.

- Description: The aim of the study was twofold namely (1) to describe and compare the incidence and mechanism of injuries that occurred in the Nelson Mandela Metropolitan University hockey teams that play in the Premier and President Leagues; and (2) to determine the relationships between the level of physical preparation of the relevant players and injury occurrence. The study utilised an exploratory-descriptive epidemiological approach, implementing a cohort study design and was conducted over a period of six months. Data collection was done by means of two physical tests, one to assess the players’ endurance and the other to assess their anaerobic fitness. This was performed twice on the participants during the study. Data collection also utilised four questionnaires to determine the following: the players’ personal information and medical history, the preparation and training the players did for hockey, the incidence and mechanism of the injury the players have incurred and the follow-up of the injury to describe the type of injury and the rehabilitation process. The study included 42 participants with 25 from the two Premier League Teams and 17 from the President League Team. The results were placed into table and graph format and elucidated by means of descriptive statistics. Furthermore inferential statistics and Cohen’s d were utilised to determine both statistical and practical significances of differences between groups mean values respectively. The statistical significance of differences between the frequency distributions of the two sample groups was determined by means of Chi2 tests of independence. Cramér’s V statistic was used when there were statistically significant Chi2 tests results to determine the practical significance of the two sample group’s differences. The variable of highest level of play showed the only significant difference with regards to screening statistics as the Premier League Participants had a higher number of years participating at a provincial level. The injury statistics revealed that the incidence of injury in the Premier League was 4.08 injuries per 1000 athlete-exposures (A-E), while there was a significantly higher incidence for the President League of 14.71 injuries per 1000 A-E. Matches showed a significantly higher incidence of injuries (8.18 injuries per 1000 A-E) than xiv practices (2.42 injuries per 1000 A-E) which follows previous research. Goalkeepers and halves showed the highest occurrence of injuries (36 percent each) and are supported by 59 percent of the injuries occurring on the defensive side of the 23 metre line. Contact injuries (collision 6 percent, hit by stick 17 percent and hit by ball 33 percent) accounted for 56 percent of all the injuries. No significant differences were found between the two leagues with regards to preparation, the Multi Stage Shuttle Run Test (MSSRT) and the Repeated Sprint Test (RST), except for one period each for technical skills and aerobic training. The relationship between injuries and training showed no significances with regards to preparation, MSSRT and RST, although there was minimal balance and proprioceptive training performed. Thus the lower league showed a significantly higher incidence of injury with preparation not being a mechanism for injuries.

- Description: By researching the life and work of Thomas Baines (1820 - 1875) in relation to a broader discourse of painting and the lived experience of being a 'white' male in a post-apartheid South Africa, I explore the ways in which this figure from the past has provoked the three series of artworks I have produced for my Master of Fine Art exhibition. This study has been divided into two parts, represented by the two chapters contained herein. Chapter One includes a critical retelling of Baines' biography and a discussion of the primary ways in which I have engaged with both the life and the working practice of this artist. I also address my own personal complicity in the constructions of 'the figure of Baines' as I have framed him both visually and textually during my work for this degree. Chapter Two describes some of the practicalities of my working process as a visual artist, including how I understand the theoretical and conceptual concerns which I raise in Chapter One to be visually manifest in my work. In this chapter, I also discuss my work in relation to the work of the contemporary South African artists William Kentridge and Johannes Phokela. The artistic practice of one artist imitating another artist's work is also explored as a central conceptual thread which could be seen to weave my verbal and visual production together.

- Description: African sharptooth catfish, Clarias gariepinus (Burchell 1822), is widely distributed with a natural range that extends from southern Turkey to the Orange River, South Africa (Skelton 2001). In addition to translocations within its southerly range (Cambray 2003), Cambray (2005) noted that as a result of poor aquaculture practices and introductions from a number of unknown sources, C. gariepinus has now invaded South America, Europe, Asia, and Australia. Its life history characteristics include a fast growth rate to a maximum length of 1300mmtotal length (TL) (Bruton 1976), a high fecundity, an omnivorous diet and the ability to breathe air (de Moor & Bruton 1988; Cambray 2003). Understanding the biology and population dynamics of this invader would assist in its management and possibly eradication.

- Description: The context of this study centres on Higher Education in South Africa, the role that this sector plays in terms of economic development and the implications that face Institutional management in retaining students in the Higher Education system. Central to this study is the notion that student development theory can be used as a basis towards understanding the customers of Higher Education, how to better serve the customers needs and finally, retain students in the system through more effective management practices. The education sector is growing at an increasingly rapid rate as a result of strategic goals of countries and organisations such as the United Nations promoting the notion of education for all people (Altbach, Reisberg & Rumbley, 2009). The aim of the strategic goals adopted by developing countries in particular is to enhance the human capital or skills and knowledge of its people since education is a known contributor towards economic, social and political development. Higher Education in particular is known to contribute towards the human capital and economic development of a country. The Higher Education sector in South Africa for instance contributes approximately 1.5 percent to the country‟s gross domestic product (GDP), significantly higher than other industry sectors (apart from gold and agriculture) in the country (van Heerden, Bohlmann, Giesecke, Makochekanwa, & Roos, 2007). Figure 1.1 provides a context of the relevant importance of the higher education sector towards economic growth.

The impact on the family dynamic of having a child and sibling with Down syndrome

- Description: The raison d'être of my research is simple: it’s about tossing one more starfish back into the surf. Down syndrome is not a disease, nor is it contagious or a death sentence (it only feels that way when you find out for the first time). At the moment of conception, the apprearance of extra genetic material results in a total of 47 chromosomes in every cell. Usually each cell has only 46, thus making an individual with Down syndrome far more like others than different from them. Yet, this extra chromosome presents special circumstances regarding their ability to acquire new skills, be it academic or practical, encompassing a specific learning profile with typical characterisitcs, strengths and weaknesses. Twenty-first century family life is simultaneously challenging and richly rewarding and the expectancy of most families are of a life lived on paved highways with well-marked signs, and rest stops never far apart. Adding an extra chromosome to the luggage sends the family travelling down a vastly different highway instead, not always knowing what is ahead. It’s scary, but in reality even those on the wide smooth roads do not know the future. Echoing the feelings of many parents, Leonard (1992: 5) states, “The trouble is that we have few, if any maps to guide us on the journey or show us how to find the path…” Assumptions from previous decades that used to increase stress associated with rearing a child with Down syndrome would negatively impact on individual family members and the family unit as such. This has made way for the growing consensus that it is not necessarily the norm. Whilst some families have trouble in adapting to the increased stress, other families adjust easier and even thrive. Successful adaptation seems more likely in resilient families who enjoy high levels of parental well-being and strong relationship bonds. Findings of this qualitative research study confirm that unresolved marital strains are more likely to result in divorce as opposed to the birth of their child with Down syndrome. Correspondingly, siblings of children with Down syndrome reported mostly positive impact than negated opportunities to participate in a normal childhood. My motivation for this research was to explore the nature of challenges faced by modern families and to provide mechanisms to facilitate positive adaptation for the family and aid vii inclusion of the child with Down syndrome into school and greater society. Recommendations are also presented for the medical professionals who, ironically, have proved to be the last people parents want to go for support, owing mostly to their decidedly objectionable treatment of parents; as well as the generally uninformed public, who seldom understand or support attempts of parents to include and expose their child to everyday experiences. In conclusion, I summarize: Should it be that I may influence but one person to see persons with Down syndrome for the potential that they hold instead of the associated problems of their condition, this would afford me the satisfaction and contentment knowing that I have succeeded in making a positive contribution to their plight. I would have successfully portrayed the families for the ordinary people they are with anticipations, aspirations and anxieties, but later tasting the elation of being empowered, and the resultant enjoyment and pride of the achievements of their extraordinary “starfish” child. The simple story below explains it all. A little boy was walking on the beach when he noticed scores of starfish washed onto the beach by the previous night’s high tide. He curiously watched as an old man bent down, came up slowly and tossed one starfish after the other into the surf. He went closer to investigate. “Excuse me, sir, what are you doing?” he enquired. The old man said: “I am throwing the starfish back into the ocean before they die, my boy…come, lend a hand”. The boy looked up and down the beach at the hundreds of starfish scattered along the shoreline. “But there’s too many…” said the boy, “it’ll make no difference!” The old man smiled, bent down, picked up another starfish, and carefully tossing it into the clear blue water, he replied, “…It makes a difference to this one…”

- Description: This study considers a Grade 9 Integrated Environmental Research Project which was implemented as a vehicle to induce knowledge-based change in learners. It was noted that change did not occur as hoped, and this study was undertaken to review the Grade 9 Project in order to improve it and to probe the apparent gap between knowledge and action. The study generated evidence on the learning processes within the project. This revealed a number of contradictions and tensions which limit change initiatives within the local environment. Notable here was a contradictory mandate between undertaking a research-based change project and responding to the rubric of assessment which was not linked to the research done. It was found that faced with this dual mandate, learners chose to focus on the assessment-laden mandate as this was the ultimate agenda that would reap the reward within the traditional school environment. The study examines the gap between knowledge and practice to probe ways in which to close this gap in the context of an environmental research assignment. The outcome is a recommendation that we as the project designers review the evidence of tensions and contradictions revealed in the study to reflect on the underlying purpose of the project and reshape it in light of recent literature on the challenges of social learning and change.

- Description: The Bayesian approach to logistic regression modelling for credit scoring is useful when there are data quantity issues. Data quantity issues might occur when a bank is opening in a new location or there is change in the scoring procedure. Making use of prior information (available from the coefficients estimated on other data sets, or expert knowledge about the coefficients) a Bayesian approach is proposed to improve the credit scoring models. To achieve this, a data set is split into two sets, “old” data and “new” data. Priors are obtained from a model fitted on the “old” data. This model is assumed to be a scoring model used by a financial institution in the current location. The financial institution is then assumed to expand into a new economic location where there is limited data. The priors from the model on the “old” data are then combined in a Bayesian model with the “new” data to obtain a model which represents all the available information. The predictive performance of this Bayesian model is compared to a model which does not make use of any prior information. It is found that the use of relevant prior information improves the predictive performance when the size of the “new” data is small. As the size of the “new” data increases, the importance of including prior information decreases

- Description: The Bayesian approach to logistic regression modelling for credit scoring is useful when there are data quantity issues. Data quantity issues might occur when a bank is opening in a new location or there is change in the scoring procedure. Making use of prior information (available from the coefficients estimated on other data sets, or expert knowledge about the coefficients) a Bayesian approach is proposed to improve the credit scoring models. To achieve this, a data set is split into two sets, “old” data and “new” data. Priors are obtained from a model fitted on the “old” data. This model is assumed to be a scoring model used by a financial institution in the current location. The financial institution is then assumed to expand into a new economic location where there is limited data. The priors from the model on the “old” data are then combined in a Bayesian model with the “new” data to obtain a model which represents all the available information. The predictive performance of this Bayesian model is compared to a model which does not make use of any prior information. It is found that the use of relevant prior information improves the predictive performance when the size of the “new” data is small. As the size of the “new” data increases, the importance of including prior information decreases

- Description: As I was involved as a voluntary, part-time teacher in a local, semi-rural school in the Eastern Cape, South Africa, I became increasingly aware of the learners' lack of English literacy. I therefore decided to do a practical research on vocabulary development, focusing on dictionary skills. In this thesis I describe how I implemented a vocabulary development programme as an Action Research project. My research group was a grade 7 class of English First Additional Language learners who had minimal exposure to English at school and in their communities. The class was a mixture of Afrikaans and isiXhosa home language speakers and the medium of instruction was Afrikaans. The school served a low-income community and was poorly resourced. As dictionary skills is a requirement of the national curriculum, I used 10 time-tabled lessons over a 5 week period to introduce the learners to dictionaries. My data sources were a journal detailing my reflections on each lesson; a video-recording of the lessons; small group interviews after each lesson which were audio-recorded; tasksheets on the work covered in class and questionnaires asking the learners for written responses to the lessons. The class teacher who filmed the lessons was also asked for feedback during and after the programme. My goals were to assess my teaching approach in these circumstances and to what extent the outcomes were positive for the learners. As I had come from a background of English Home Language teaching in good, well-resourced schools I found I had to question many of my assumptions. Although I was an experienced, qualified and confident teacher, I was continually having to reassess my teaching methods which were being challenged by very different classroom conditions. The outcomes of the research show why I was not able to achieve what I had thought I could in the time given.

- Description: Diamond compacts consist of fine diamond grains bonded together by using high pressure and high temperature. In this study transmission electron microscopy (TEM)was used to study thermal degradation of diamond compacts. Three different types of diamond compacts – namely cobalt polycrystalline diamond (PCD), calcium carbonate PCD, and diamond-SiC composites – were investigated with TEM to understand the processes that occur during synthesis. These compacts were then heated in inert atmospheres and the chemical changes studied with TEM. It was found that PCD, using cobalt as a bonding agent, will degrade after exposure to temperatures above 750ºC. The cobalt pools contain tungsten in solid solution. During heat treatment above 700ºC the solid solution tungsten combines with cobalt and dissolved carbon to form η-phase particles at the cobalt/diamond interface. At higher temperatures or insufficient tungsten levels the rate of dissolved carbon, into the cobalt pool, is too high and the excess carbon will form as graphite in the cobalt pool. Increased levels of solid solution tungsten, in the cobalt, is expected to delay the onset of graphitization in the diamond compact, thereby increasing the thermal stability of the diamond compact. Non-metallic PCD using calcium carbonate as a bonding agent was successfully sintered in this study. TEM revealed similar micro-structural features as in cobalt based PCD. No signs of thermal degradation were found after exposure to 1200ºC in vacuum for this PCD. Contaminants introduced during processing prevented a detailed study of the binder in this system. The effect of substitutional metal atoms and plastic deformation of diamond on the thermal stability of diamond-SiC composites were investigated. A piston cylinder press was developed and used to synthesize diamond-SiC composites with different levels of plastically deformed diamond. It was concluded that substitutional metal atoms and plastic deformation of diamond grains play no role in the thermal degradation of diamond compacts at 750ºC. The thermal degradation of cobalt PCD is therefore completely determined by the cobalt/diamond interaction at 750ºC.

- Description: Despite the demand for ICT skills, businesses are experiencing an ICT skills shortage. Constantly changing ICT technologies require business leaders to find qualified ICT professionals to implement new business strategies and business processes. The Information and Communications Technology (ICT) sector is experiencing a continued skills shortage and various initiatives have been launched to address the problem. Businesses continually struggle to find qualified and suitably skilled ICT personnel. As a result businesses have had to outsource their ICT requirements off-shore to obtain the required ICT skills and maintain their competitive advantage. In a country desperate for job creation, entrepreneurial inclination and start up of new businesses may play a pivotal role in the economic development and well being of individuals able to capitalise on the availability of ICT opportunities. Entrepreneurship is a critical factor in promoting innovation, creating employment opportunities and generating social and economic wealth in a country's economy. Sectors such as Information and Communication Technologies can be seen as archetypal entrepreneurial industries and can consequently play a key role in economic development. In the research that follows the author identifies an ICT skills shortage in South Africa. This is followed by an exploratory study that investigates the influence of psychological traits and socio-cultural variables on the entrepreneurial intent of selected ICT SMME’s in the Nelson Mandela Metropolitan Area. The findings revealed that both psychological traits together with socio-cultural variables influence an individual’s intention to start up a business. The predominant psychological trait discovered during the research was perseverance. Family environmental issues were the dominant socio-cultural variable influencing entrepreneurial intention amongst the case study subjects.

- Description: This research study aimed to provide the South African fast food industry and their advertising representatives with insights into 18-28-year-olds‟ perception of using sexual appeal to elicit their attention, and whether using this advertising technique is gaining positive brand recognition with this target market. This research study aimed to determine the selected sample‟s (NMMU students) perceptions of three South African fast food brands, namely KFC, Nando’s and Steers, in terms of their use of sexualised fast food advertisements. An electronic survey questionnaire was conducted with both closed and open-ended questions relating to the use of sexual appeal in advertising within the three South African fast food brands. The survey questionnaire helped determine what the selected sample‟s perceptions were of each advertisement, and whether the use of sexual appeal captured their attention. A semiotic analysis of each advertisement was conducted to determine if the advertisements do contain the use of sexual appeal, by examining the sign. This includes looking at the three aspects of a sign namely the signifier, the referent and the signified. In terms of this study, the signifier represents the T.V. advertisements; the signified represents the meaning of the advertisements and the referent represents to what the advertisements are initially referring. The results of the study indicated that each of the three fast food advertisements incorporated the use of sexual appeal in varying degrees. Respondents indicated that the sexual appeal in the advertisements was appropriate if they were directed at the right age group. The respondents indicated that these three advertisements were more likely to attract the males, in the target market and they felt that the advertisements leaned towards objectifying the women, which would be offensive to the females in the target market. It was determined that if the advertisements contained humour, they were more effective and memorable.

- Description: The study presented here describes an attempt to bridge the gap between systematic conservation assessment and decision-making for land-use planning in the Eastern Cape province, South Africa. The aim was to investigate how to effectively convince officials concerned with land use planning processes in the local municipal sphere to include conservation priorities meaningfully in their processes. The approach used to reach this aim was social marketing, the use of marketing technologies and concepts to effect behavior changes to further societal good. So far social marketing is not commonly used in the conservation domain; I therefore aimed also at proving the usefulness of this approach for conservation. Following the introduction which provides background to the project and a more detailed summary, Chapter 2 provides a detailed and comprehensive review of the considerations and concepts regarding the use of social marketing in a context geared at protecting nature. The research on the primary target group for this study, officials concerned with land use planning processes in the local municipal sphere is described in Chapter 3. The main outcomes were that land use planners perceive few needs with regards to implementing the incorporation of biodiversity conservation issues in the land use planning process, and that the deficiencies in the land use planning process per se, as well as the lack of recognition in the political sphere (the domain of elected councilors), represent the core barriers to adopting the conservation priorities. I conclude that to effect behavior change towards adoption of conservation priorities the land use planning processes need to be supported and the political sphere need to be included in the behavior change process. 6 Chapter 4 therefore focuses on the new target group that emerged as essential in the previous chapter, locally elected councilors. I found that councilors do actually consider land use planning procedures as being important, but also as being dysfunctional. Councilors do value their natural environment for themselves as well as for its tourism value, but most councilors had little understanding of what the term “biodiversity” means and did not connect the term “sustainability” with the natural environment. It became also evident, that councilors do not see conservation in a predominantly positive manner. Chapter 5 therefore yields insight on councilor’s perception that environmental protection and development are mutually exclusive, and the negative frames attached to the conservation endeavor as being socially unjust, disrespectful and utopian. In Chapter 6 I investigated the usefulness of a tractable and well established measure of environmental attitudes or beliefs. I assessed my target audience’s responses to the New Ecological Paradigm scale and the Inclusion of Nature in Self scale. I conclude in Chapter 7 with an account of the difficulties I encountered during the project, an assessment of my project from a social marketing perspective, components of my project that did not yield the results expected, and a proposal for future research.
