- Description: Due to the growth increase in the wool industry in South Africa and the industry's lack of public activity that the existing South Africa (S.A) wool exchange exudes, the opportunity for a new type of wool exchange presents itself. the advantages in technology have evolved in many an industry and the same can be for the wool industry. the existing S.A. wool exchange fails to comfortably meet the needs of the industry with regards to technology. the creation of international wool exchange will provide a platform to boost the industry and incorporate the use of current technology to improve on the process involved within the program. BKB. Ltd have expressed a similar interest in the development of an international wool exchange but have requested the use of an abounded heritage building in an attempt at a sustainable future through re-use.

- Description: Purpose – This study seeks to explore residents’ attitudes towards cultural events in Nelson Mandela Bay (NMB), South Africa. The study further discusses the cultural values and social realities of the diverse socio-economic landscape inherent to the city. Equally, the extent of stakeholder involvement has been reflected throughout the study as an indispensable requirement towards sustainable tourism in the city. The study presents that customising cultural events according to the cross-cultural typology has far-reaching consequences in enhancing the image of NMB and induces stakeholder engagement. This study is based on the notion of Social Capital and Stakeholder theory and draws on the multi-cultural phenomenon as the thrust of the study is based on attracting residents’ to cultural events. The literature study indicated that the concept of Social Capital and stakeholder collaboration are mutually exclusive and empirical analysis indicates a strong relationship between the factors relative to residents’ attitudes. Design/Methodology/Approach – This study is located in the positivism paradigm and comprises literature and exploratory research to examine the supposition between the independent variables and the attitudes of residents’ in the NMB. The independent variables underlined in the proposed model are embedded in the literature undertaken. Equally, the thrust of the study is underpinned in Social Capital theory and the Stakeholder theory and is evident throughout this study. In this study, the convenience sampling and snowball sampling methods were employed to obtain a representative sample of residents from the NMB. A questionnaire was used in this study to solicit responses pertaining to the biographical information and questions relating to the factors of perceived satisfaction of residents in the NMB in relation to cultural events. A total number of 3,659 residents participated in this study. The researcher conducted this study by means of testing the constructs of the measuring instrument employed, as well as providing a causal model of relationships between the independent variables and the residents’ attitudes of cultural events in NMB. Findings – The results confirm the reliability and validity of the scales tested on a sample of 3,659 residents, collected using the questionnaire in Nelson Mandela Bay Metropolitan area. The empirical analysis indicates relationships among the independent factors; Social Capital and Stakeholder Profile, where a Pearson’s correlation of 0.50 exists. Furthermore, descriptive findings indicate that there is an overall positive tendency in attitudes for cultural events in the city. The practical significance as identified in the Cohen’s d test for significance infers that the moderating factors in the conceptual model prove that age, area code, home language, ethnicity and home language exert influence in determining residents’ attitudes in the city. Practical Implications – This study identifies the importance of leveraging the cross-cultural typology underscored the Stakeholder theory. Equally, for destination marketing organisations (DMOs) this study can glean insights in respect of the profile of residents for cultural event marketing and their response as stakeholders in the organisation of a cultural event. Social Implications – This study aims to gain a better understanding of the residents’ attitudes of the cultural events hosted by the NMB, its Social Capital and its relationship with varying demographic niches and cultural-centric insights that align to the ideologies pertaining to global citizenship. Originality/Value – This present study makes a contribution to the theories of Social Capital and Stakeholder theory by investigating its roles in determining residents’ attitudes of cultural events in a city. Moreover, it discusses the role of the factors as inducing variables for residents’ motivation by employing marketing principles related to the unique and emotional selling proposition philosophy. Equally, the study espouses the significance of promoting cultural events to extent that it acts as a platform to promote socio-economic development; employment opportunities, improved living standards, improving city infrastructure and environmental protection of a destination and justifies the expedition of Social Capital on the attitudes of residents’.

- Description: The Story of clay in the Grahamstown area can be dated as far back as 1812. In 1823 there was conflict between the Xhosa and the British Settlers over clay pits at Coombs valley, an area outside Grahamstown towards East London (Holleman, 1997, p. 50). Since the initial conflict, the mining of the resource has become a commercial activity. Pottery industries, brick making facilities and a kaolin mill were opened, with brick making being the only economically sustained activity which continues to present day. With the largest known deposits of quality kaolin in South Africa, the economic condition of the context of Grahamstown is not benefitting from the abundance of the raw-clay material (Malatji, 2010). The material is currently being mined at Strowan mine, the most active mine in the area, approximately 4km from Grahamstown and is transported to Johannesburg for milling. The transport costs involved in moving the material from the mine to the mill has impeded potential production. In 1988 the production of Kaolin from the Grahamstown area accounted for 55% of total local production in South Africa, but that figure had dropped to 27% by 2008 (Horan, 2008, p.1). The high waste factor and the cost implication involved in the erecting of the required infrastructure and equipment for a mill, become the main impediment to erecting a new Kaolin mill in Grahamstown. The raw material which is milled has a waste factor of approximately 90 percent, meaning that; of the material mined in the open cast mining method, less than 10 percent is transported to be milled (Burchell, 2015). Capital gain from production of kaolin in relation to the cost of the mill is inadequate to financially sustain the costs of erecting a kaolin mill for Grahamstown. A need for a by-product to utilize the high waste content of the mined product in a waste resourceful manner will potentially sustain a new mill economically. With the problem of transport and foreign provincial exploitation of local resources, a kaolin mill for Grahamstown will increase production and potentially become a catalyst for future development around kaolin supporting industries such as ceramics, paper industries, cosmetics and pharmaceuticals. This treatise is a strategic approach towards the design of a Kaolin mill with a brick making factory as a by-product of the waste of the high quality kaolin.

- Description: The Garden Route is situated between a mountain range and the ocean, both within close proximity. These geographic considerations make the farmers in the area vulnerable to extreme weather events, especially droughts and floods, which have been experienced in recent years. Agriculture in the area is predominantly focused on dairy and vegetables, which require intensive irrigation practices. It is this water demand that inspired adaptations to counteract the risks of extreme weather and dwindling water sources. These adaptations and behaviours were investigated to determine the underlying perceptions and influences. The research aimed to understand the way environmental knowledge would disseminate through the use of the Diffusion of Innovation theory, whilst determining the ecological worldviews of the participants through the use of the New Ecological Paradigm (NEP) scale. Both of these theories proved effective in researching the ecological perceptions of and various influences on the participants, with a few minor drawbacks. The data analysis investigated the research questions with a three-pronged approach. Interpersonal interviews and media content analysis of the local and agricultural media in the area was followed by analysing the two sets of findings, in order to find overlaps and relationships between the factors explored. The interviews were designed as semi-structured to allow for themes to emerge and were conducted mainly within the diary and beef industries, consisting of 24 participants. The media content analysis incorporated a niche agricultural magazine (32 articles) as well as the local newspaper (74 articles). The articles were coded for themes to allow for comparison between the two, and to provide an overall understanding of the media coverage. The use of the interviews and media content analysis concurrently, made it possible to determine the farmers’ perceptions of water conservation and the possible influences on these. By exploring this, the research endeavours to understand the dynamics between the farmers’ use of media and interpersonal networks and their water conservation practices. The farmers’ perceptions appeared to be predominantly shaped by agricultural media and interpersonal communities. The NEP scale responses exposed the clash between economic and environmental considerations. The farmers were acutely aware of their ecological impact and were employing various measures to counteract it. However, these were heavily dependent on their financial situation. This is in contrast to the NEP scale’s measuring of NEP statements contrasted with Dominant Social Paradigm (DSP) statements to determine ecological attitudes. These findings confirm previous research and demonstrate that modern farmers are more likely to adopt conservation practices than their traditional counterparts, if it helps achieve their economic, social and environmental goals. The importance of the historical context of South Africa’s water issues emerged, with the past and future proposed changes to water regulation and legislation affecting farmers’ perceptions. The move from agriculturally privileged water legislation to equitable distribution is affecting the farmers negatively, causing distrust towards the government. The research was successful in achieving an understanding of the effect of the mass media and interpersonal communication influences on the farmers’ perceptions of water conservation.

- Description: This study explored and described the experiences of students with self-reported symptoms of anxiety and depression who participated in a mindfulness-based intervention. The study was conducted in collaboration with the Student Counselling Career and Development Centre (SCCDC) at the Nelson Mandela Metropolitan University (NMMU). The study utilised a qualitative research approach and nine participants were selected through purposive, non-probability sampling. The data were collected by means of semi-structured interviews and participants‟ brief written reflections of their individual experiences. Content analysis produced ten themes categorised according to the components of the biopsychosocial/spiritual (BPSS) model. The most prevalent theme identified, describing participants‟ experience of the mindfulness-based intervention, was an enhanced perception of emotional regulation. This finding confirmed the outcomes of previous studies that also found an increase in emotional regulation related to mindfulness-based interventions. Results also shed new light on the perceived personal changes participants experienced in relation to body awareness, increased attentional regulation, social interactions, and spiritual experiences. In addition, participants verbalised present moment awareness and an accepting non-judgmental attitude as central to the biopsychosocial/spiritual changes and benefits they experienced. Recommendations for further research include investigating the impact of mindfulness-based interventions on attentional control and social interactions.

- Description: Modern automobiles are painted with basecoat, technology which is either metallic, solid colour or pearlescent. This requires protection from chemicals, scratching, weathering and UV light by applying a protective top coat (clearcoat) over the basecoat. For the clearcoat to cure into a hard protective shell it undergoes an irreversible crosslinking process. This usually takes place over the first four to five hours, depending on the formulation and weather conditions. The speed of crosslinking can be enhanced by temperature. Pot life is important as it can affect the overall quality of the painted surface. If crosslinking occurs too quickly, before the clearcoat is applied onto the surface, the clearcoat cannot be used to produce a good quality finish. The “expired” mixture is thus discarded. If used, the quality of the finished product cannot be guaranteed to last, and the paintwork may have to be redone. This often means removing the underlying paint and primer as well with the clearcoat film. Besides the time lost, the discarded clearcoat mixture often lands in the landfill, polluting ground water and the environment. It is thus important from the point of view of both the environment preservation and waste management, that as much clearcoat as possible is used without being wasted. It was proven in an earlier study (BSc Hon Formulation Science Treatise, 2011) that adding eugenol to a clearcoat mixture after crosslinking had started could reduce its viscosity, which is an indicator of crosslinking progress. Crosslinking subsequently resumed at a lower rate than in traditional blends. If stored away from oxygen and high temperatures, this blend could maintain optimum viscosity indefinitely. In this follow up study an optimum formulation was developed using D - optimal experimental design. It sought to extend the pot life to avoid waste to spray painters while saving the environment from pollution. The formulation that gave the desired viscosity after five hours of pot life was adopted. It was hypothesised that the optimum formulated clearcoat mixture would have a longer pot life than its traditional counterparts, and that it would perform just as well as the traditional clearcoat mixtures. To study the rate of crosslinking (disappearance of functional groups and appearance of the urethane bond), FTIR spectrometry was performed on a mixture produced from the optimized formula in comparison to that of a traditional mixture (the control). The rate of disappearance of functional groups was found to be lower in the eugenol mixture than in the control mixture. After six hours, eugenol was added into the control mixture, and this seemed to reduce the viscosity with the re-emergence of functional groups in the mixture. After 24 hours of crosslinking, an FTIR scan was done on the solid sample and this revealed that the eugenol mixture had crosslinked fully, with no detectable functional groups in the sample.

- Description: This treatise is centered on the design of a digital resource centre in the township of Motherwell, Port Elizabeth. The building is concerned with providing a civic space which promotes access to and effective use of digital information and communication technologies. The treatise explores the issues and methods involved in the design of a public digital resource centre. The research starts with an investigation into the nature of public space and civic facilities within a South African township context before exploring the development of the library typology and its evolution in the digital age, while exploring the issues and processes involved in the design of a civic building in a township environment. The architectural design is seen as an appropriate response to the identified architectural issues. Relevant precedents are chosen based on the nature of these issues and the context in which they are situated. The buildings are analyzed in terms of these key issues and will thereby provide an understanding of the architectural identity of the civic building archetype. An understanding of the architectural typology and an analysis of relevant precedents leads to the identification of a set of site selection criteria which can be used to select an appropriate site within the Motherwell precinct. The nature of Motherwell and the identified issues related to the selected site are then investigated in order to develop a set of informants and constraints. Specific elements which are unique to the selected site are then investigated individually while using relevant precedents to establish an appropriate response to the issues involved. An appropriate architectural response is then developed through an understanding of the physical and spatial qualities of the building typology while also responding to the specific issues related to the site.

- Description: A distinctive destination image is required in order to compete with other destinations for tourists and investors alike. This main objective of this study is to develop a model for destination image formation for Nelson Mandela Bay as a secondary economy to boost its global competitiveness. Several researchers have studied destination image and based on the fact that tourists and investors usually have a limited knowledge of destinations they have not previously visited, destination image fulfils an important function insofar as destinations with strong, positive, discriminatory and recognisable images. A literature study was conducted to identify the key influencers on destination image as well as to identify which forces are likely to influence the destination image of Nelson Mandela Bay. The different factors of destination image were identified from the literature sources and these factors provided a basis for an empirical study that was conducted amongst external stakeholders. The primary research objective was to create a model of destination image for Nelson Mandela Bay and to explain the cause and effect relationship between the dependent and independent variables. Added to the primary research objective, eight secondary research objectives were identified. The primary research question for this study was to identify what influences the destination image of Nelson Mandela Bay. Added to the primary research question, the researcher also identified eight research questions as part of the study. The empirical analysis was used to test the hypotheses and ultimately develop a model for destination image formation for Nelson Mandela Bay. This study was exploratory in nature and thus used a limited sample to gain insights for further research. Data were obtained through questionnaires that were distributed electronically to 120 respondents. This study concluded with the development of a destination image model for Nelson Mandela Bay that can be expanded upon with further research. The results indicate that general infrastructure and social environment; leisure and recreation; and culture influence the Affective component of Nelson Mandela Bay. Information sources and Political stability and risk influence the Cognitive component of Nelson Mandela Bay. Together the Affective and Cognitive component makes up the overall image of Nelson Mandela Bay.

- Description: Parents’ perceptions of their adolescent children’s Internet use significantly influences the parental mediation strategies they choose to use with their children. The motivation for this explorative research study was to understand the impact of psychological and social influences on users of the Internet in South Africa. Both locally and internationally, there is a focus on the use of digital Internet devices to facilitate education. Access of South Africans to the Internet, whether for social or educational use does not exist in a vacuum, exempt from the bidirectional forces of the individual and the environment they use the Internet in, whether it is family or academic. This study firstly focusses on how parents perceive their adolescent children’s Internet use, and secondly, how they parent their children’s use of the Internet. The common topics and themes that emerged from this study allow for the development and provision of professional services that individuals, couples, families, and groups require for the use of, or exposure to the Internet. This study uses an explorative-descriptive qualitative research design with an interpretive paradigm and snowball sampling. The qualitative research design focussed on the concepts of self-reflexivity, context, and thick description while utilizing multivocality of 1) international and South African research on cyber citizenship, including cyberbullying, cyber harassment, and legal consequences, with 2) psychological aspects of the psychosocial developmental challenges of adolescents from the iGeneration including the benefits, risks, and dangers of using the Internet, and 3) qualitative data collected from semi-structured interviews with parents from Generation X who are raising and educating a generation of children on the other side of the Digital Divide. Tracy’s 8 ‘Big-Tent’ criteria for guiding excellence in qualitative research and Tesch’s model of content analysis was used during the content analysis process. Themes and sub-themes that emerged from the analysis of the participants’ narratives included 1) experiences: positive and negative, 2) observations: behavioural changes and gender differences, 3) parenting methods: parental interaction, rules, and limits, 4) concerns: risks, and 5) opinions: personal views. This research study provides a thick description of South African and international literature and combines the literature with the voices of the participants and the researcher to produce discussions based on the findings of this qualitative study. Conclusions, recommendations, and limitations of this study informed future research on cyber citizenship by providing a detailed understanding of the context of South African parents and children, the psychosocial developmental challenges of adolescents and, how educational programmes can be best created to effectively impact on the generations of parents, teachers and children in South Africa.

- Description: This study explores the phenomenon of educator targeted-bullying (ETB) by learners as an educational problem in terms of the incidence, frequency, severity and the impact on effective teaching and learning in classrooms. Abuse or bullying in schools usually happens amongst learners or to learners targeted by educators. However, the phenomenon of educator abuse by learners is escalating, internationally as well as nationally, and is experienced by many educators, especially by those teaching in secondary schools. An extensive literature review on numerous research national and international studies reports on the fact that the bullying of educators in all its forms, including physical, verbal, emotional and cyber bullying, impacts negatively on the emotional and psychological well-being of educators who are also stressed by other work demands, resulting in ineffective teaching and learning experiences in schools. The over-arching purpose of this local study was to determine the impact of ETB by learners on the effectiveness of teaching and learning in classrooms. In addition, other aspects of ETB were examined, namely the types of bullying, its severity and frequency, and the emotional and psychological effects on educators’ general well-being as victims. The study was conducted in a private high school in the Nelson Mandela Metropolitan area, Eastern Cape, South Africa. A qualitative methodology was used and all the educators employed at this particular school took part in the study. Convenience sampling was thus applied in the selection of the participants and questionnaires and written narratives were used as data gathering instruments. Twelve educators completed questionnaires to gather information-rich qualitative data to investigate the abovementioned aspects of this study. Four educators wrote narratives on their experiences of ETB by learners in this school context. The results of this research provided valuable evidence that ETB by learners in this school has a distressing impact on the educators and their psychological well-being, impairing teaching quality and learning outcomes in classrooms and, ultimately, with adverse educational consequences for all learners. The theoretical framework for this study was based on the ecological systems theory of the developmental psychologist and theorist, Urie Bronfenbrenner. Bronfenbrenner (1979) suggested that the process of human development is shaped and moulded by a person’s v environment and all the people and institutions that play a role in that environment. In my view, this theory may explain to some extent why some children are moulded and shaped as bullies as a result of the child’s exposure to and interaction with his/her environment. The main findings of this study include the fact that ETB is a serious phenomenon that an increasing number of educators are exposed to. It also appears that the incidences are becoming more severe and involve serious physical threats and bodily harm. Educators are also exposed to ETB on a regular basis, with many educators being bullied on a daily basis. It is clear that verbal abuse is the most prominent form of ETB leading to emotional damage, feelings of incompetence and reduced motivation to teach with innovation and enthusiasm. This in turn leads to the very concerning fact that ETB negatively affects successful teaching and learning in classrooms, adding more problems to an already embattled education system. Participants also provided some guidelines to reduce and possibly prevent ETB by learners. In doing so, these data can hopefully be used in the formulation of anti-bullying programmes for educators, which can result in safer working environments and more effective teaching and learning for learners.

- Description: Small and medium-sized enterprises (SMEs) are recognised internationally and in South Africa as a critical component of the economic development of a country as a result of their contribution to job creation, alleviation of poverty, sustainability and innovation. Furthermore, the majority of SMEs are also family-owned and play an increasingly important role in the South African economy, making up approximately 84 per cent of businesses in the country. Despite the critical role that family and non-family SMEs play in economic development, they are still plagued with high failure rates and unique challenges that make it difficult for them to survive. These challenges include, amongst others, regulatory burdens, restrictive labour policies, a lack of access to finance, markets and technology, as well as an overwhelmingly constant emphasis on survival. As a result of the added dynamic of family relationships within family-owned SMEs, they face additional challenges such as conflict between family members and inadequate succession planning. Focus is often placed on the factors leading to failure, but little is known about success-aiding behaviours that could reduce the high failure rate and improve the success rate of these businesses. As a result, it is important to examine what determines success and how it is measured. Success can be defined as the attainment of goals, therefore the achievement of goals plays a critical role in the success of the business.

Knowledge of a seabird’s diet and at sea distribution is therefore critical in deducing the effect of a fluctuating environment on a seabirds’ population and, furthermore, to understand seabirds role in the environment. The gentoo penguin population at sub-Antarctic Marion Island experienced a decline of 52% between 1994 and 2012. It has been speculated that long term changes in the local marine environment, due to a southward shift of the sub-Antarctic Front (SAF), and subsequent changes in prey availability is the ultimate causal factor. Therefore, this thesis investigates the temporal variation in the diet these birds over three years, through the use of stomach content samples. It then investigates whether the composition of the diet has changed over the long term (approximately 18 years). Additionally, the at sea distribution of these birds was investigated using temperature-depth recorders (TDRs) and global positioning system (GPS) devices. This study represents the first to investigate variation in the diet over three years and over the long term. It is also the first study to track these birds fine scale movement. Over three years, the diet exhibited a high degree of variability. The birds primarily foraged on the fish, Lepidonotothen larseni and the crustaceans, Nauticaris marionis and Euphausia vallentiniy. Over three years, L. larseni became increasingly more important during the breeding season. This was attributed to an increase in availability of these fish during this time, as this time corresponded to the transition of these fish from the larval pelagic phase to the benthic adult phase. Furthermore, the proportions of N. marionis and E. vallentini in the diet varied significantly among years. This variation is possibly a result of the highly variable latitudinal position of the SAF. The diet changed over the long term. There was significantly less N. marionis and more E. vallentini in the diet during more recent years. The long term southward shift of the SAF is considered to be a leading cause of these significant changes in the diet. The shallow inter-island shelf between Marion and Prince Edward Island was an important foraging area possibly due to predictable prey resources. In addition, these birds exhibited an important and possibly unique foraging strategy. They performed short self-maintenance trips where after they return to land to roost for the night. The following day these trips were followed by a longer foraging trip that was followed by chick provisioning. This strategy is unique among seabirds longer trips are associated with self-maintenance and not chick provisioning. This study has provided important knowledge of the foraging ecology of the gentoo penguin at sub-Antarctic Marion Island. It highlights the necessity for continuation of diet and tracking studies of these birds if we are to fully understand the ultimate factors that are causing the decline in their breeding success and population numbers.

- Description: This study was undertaken to describe how the community responded to the incorporation of the Merafong Municipality into the North West Province. The study examined the protracted conflict in Khutsong as well as why the strategies to end the conflict failed. The study was concerned about latent conflict; how differences are raised; dissatisfaction amongst members of the communities and that power asymmetry is the main driver of emotions leading to aggressive behaviour. Service delivery protests are characterised by violence in South Africa and more often communities turn violent in their engagement with their leaders or council officials. This is because it is believed that violence is the only language that authorities understand and they have nothing to lose as government property gets destroyed. Late invitations of third parties who have regulatory skills (negotiations, mediation, conciliation or judicial processes) when conflicts begin, lead to their escalation. A qualitative research method was chosen for this study. A qualitative case study better explained the phenomenon of interest. It allowed me to collect data from the respondents who were active members of the community through interviews. Twelve members of the community (from politicians, ordinary members, educators and the clergy) were part of the respondents. The report was of the respondents own personal experiences as active members of the community. Collected data from the transcripts was coded. Codes with similar meaning were put together in the same categories and the themes were formed from the categories. The qualitative content analysis method was used to analyse the data. From the analysis, it emerged that there was lack of communication and consultation from the side of the government before the implementation of the 16th Amendment Bill which was aimed at removing the cross border municipalities. The announcement was finally made of the incorporation of the Merafong Municipality into North West Province in 2005. The announcement was met with anger and frustration by the Khutsong Demarcation Forum and the community whose expectations were that the incorporation will not go ahead given the reasons they put forth when they met the government officials in the meetings after the demarcation board had proposed it. Violence was the only option for the community to show that their talks with government officials failed and that they are seriously opposed to the incorporation. That led to a protracted violence in Khutsong until 2009 when the Cross-Boundary Municipalities Laws Repeal and Related Matters Amendment Act of 2009 act was passed to reincorporate the Merafong Municipality back into Gauteng.

- Description: Universities are facing growing pressure to contribute towards innovation which has social impact and which contributes to economic development. Researchers mainly in the Science and Engineering fields are the primary sources of innovation outputs from universities and as such their involvement in commercialisation activities directly adds to the growth of innovative outputs from publicly financed research. Technology Transfer Offices (TTO) have been established at universities across South Africa to foster the involvement of researchers in commercialisation activities, to champion the innovation conversation within higher education institutions and to progress innovations from concept to application in society. This study focussed on understanding the factors which enable or create a barrier to the involvement of researchers in commercialisation activities at the Nelson Mandela Metropolitan University. The key elements examined in this study include the researchers’ perception of enablers (monetary and nonmonetary incentives) and barriers to involvement at national, institutional and individual levels. This study undertook to understand the perceptions of researchers of enablers and barriers to involvement in commercialisation at the Nelson Mandela Metropolitan University. Researchers in the two faculties of Science and Engineering, Built Environment and Information Technology were approached to anonymously complete an electronic survey, the questions for which were developed from literature. The results from the survey were analysed using descriptive statistics and hypothesis testing. This study finds that a combination of incentives is necessary to enable researcher involvement and to lower barriers to involvement in commercialisation research. A set of recommendations based on the study are put forward on how such recommendations can be implemented.

- Description: The aim of this study is to illustrate how, in the design of costumes, adopting design elements used to produce conceptual fashion can create conceptual costumes that have the ability to express emotions. The play Sounds of South End (2013) contains such qualities; therefore it has been selected to illustrate how the mood and emotional trajectory of a play can be interpreted through symbolism. The play illustrates the life before and after the forced removals during the apartheid (1960s and 1970s), of a fictional family, the Dietrichs, who live in South End, a suburb in Port Elizabeth, South Africa. A focus on the nature of emotional changes experienced by the family has been used to determine the overall mood of the play, leading to a translation of the shifting mood through a collection of conceptual costumes. The final collection was exhibited as an installation artwork that is an interpretation of the altering moods and emotions that occur in the life of the Dietrich family as the play unfolds. The conceptual costumes have been constructed to imbue the narrative of the play with deep meaning by using symbolic elements, such as colour, texture and weight, to suggest the emotional trajectory within the play. The eight costumes portray the interrelated gradual decline and resultant deterioration of human relations experienced by the Dietrichs, from a contented state of harmonious living to a wounded state of despair.

- Description: Theoretically, the use of Electronic Medical Records (EMRs) holds promise of numerous benefits in healthcare provision, including improvement in continuity of care, quality of care and safety. However, in practice, there is evidence that the adoption of electronic medical records has been slow and where adopted, often lacks meaningful use. Thus there is a clear dichotomy between the ambitions for EMR use and the reality of EMR implementation. In the USA, a legislative approach was taken to turn around the situation. Other countries such as Canada and European countries have followed suit (in their own way) to address the adoption and meaningful use of electronic medical records. The South African e-Health strategy and the National Health Normative Standards Framework for Interoperability in eHealth in South Africa documents both recommend the adoption of EMRs. Much work has been done to establish a baseline for standards to ensure interoperability and data portability of healthcare applications and data. However, even with the increased focus on e-Health, South Africa remains excessively reliant on paper-based medical records. Where health information technologies have been adopted, there is lack of coordination between and within provinces, leading to a multitude of systems and vendors. Thus there is a lack of systematic adoption and meaningful use of EMRs in South Africa. The main objective of this research is to develop the components required to engender meaningful use of electronic medical records in the South African healthcare context. The main contributors are identified as EMR certification and consistent, proper use of certified EMRs. Literature review, a Delphi study and logical argumentation are used to develop the relevant components for the South African healthcare context. The benefits of EMRs can only be realized through systematic adoption and meaningful use of EMRs, thus this research contributes to providing a road map for engendering the meaningful use of EMRs with the ultimate aim of improving healthcare in the South African healthcare landscape.

- Description: Cancer procoagulant (CP) is a cysteine protease found in tumour cells and amnion chorion membranes. The main function of CP is not yet known, but it has potential roles in tumour growth and metastasis. Initially, CP was believed to increase coagulation in cancer patients; however, research has shown that increase in CP concentration does not correlate with an increase in coagulation. The location of CP in amnion chorion membranes and tumour cells only led to the hypothesis that CP might be involved in inducing blood vessel and or lymph vessel formation. CP was shown to induce lymphangiogenesis (lymph vessel formation) in human telomerase reverse transcriptase-human dermal endothelial cells (hTERT-HDLEC) (Tshaka, 2011). CP-induced tube formation was inhibited by rapamycin; indicating that CP may be signalling via the mammalian target of rapamycin (mTOR) pathway. The aim of this study was to investigate the effect of CP on the mTOR signalling pathway using human umbilical endothelial vein cells (HUVECs) as a model. CP was isolated from amnion chorion membranes and purified using two anion exchange chromatography steps. Purified CP (2 μg/ml) was used to induce tube formation in endothelial cells (HUVECs) seeded on growth factor reduced (GFR) Matrigel. In addition, the 2 μg/ml CP was used to treat cultured HUVECs. Sodium dodecyl sulphate polyacrylamide electrophoresis (SDS-PAGE) and western blotting were used to determine phosphorylation levels of protein kinase B (Akt) and ribosomal protein S6 kinase (S6K). CP was successfully isolated and purified using anion exchange chromatography. The effect of CP on tube formation was not significant relative to the control in the HUVEC cell line. The role of CP on Akt and S6K phosphorylation still needs to be verified by using sensitive methods of quantification such as enhanced chemiluminescence (ECL) and enzyme linked immunosorbent assay (ELISA). The levels of CP activity were shown to be higher in early tumour growth than in advanced cancer suggesting that certain physiological factors could be increasing CP activity during early tumour growth. This study investigated the effect of cobalt chloride on CP activity in breast cancer cell lines. Cobalt chloride reduced CP activity in MCF-7 and promoted CP activity in MDA-MB-231.

- Description: With the increase in electronic equipment implemented in various systems, as well as the increase in calculating power that these devices offer, designers are being empowered to make use of this power in real-time systems to diagnose and protect the systems themselves. This reasoning is too compounded by the focus on efficiency and safety in the design of complex systems, as well as the increasing expense and sensitivity of the electronic components themselves. With this in mind, this dissertation aims at developing a comprehensive measurement, control and reaction system for the electrical diagnosis and ultimately optimisation of complex electrical and electronic systems. This system will serve as a real-time diagnosis tool, which will enable the real-time diagnosis of various components in an electro-mechanical system, which can then be interpreted to determine the working state of the various components. Another sphere of this project will involve the accurate monitoring of the battery status as well as actively balancing the series connected batteries. The focus on the batteries will seek to prolong the life of the batteries, while being able to squeeze as much capacity out of them. The initial design and testing will be based on an AGV system implemented at VWSA, however a main goal throughout the design process will be modularity, i.e. the ease of implementation of this system in other systems. The key technologies used in the development of this system will still comprise of the components used in the original AGV, however new prototype components sourced from Microcare are used for the battery management system, while current sensors directly connected to the PLC’s analog input ports will be used for the active monitoring of currents distributed through the AGV.
