- Description: This work reports on conjugation of low symmetry Ge (GeMCPc), Ti (TiMCPc) and Sn (SnMCPc) carboxy phthalocyanines with glutathione capped gold nanoparticles (GSH-AuNPs). The photophysical behaviour of the novel phthalocyanines–GSH-AuNPs conjugate was investigated and compared to the monocarboxy Pcs and to the mixture of Pc with GSH-AuNPs without a chemical bond. Blue shifting of Q band of the phthalocyanines was observed on linking to GSH-AuNPs. An improvement in triplet lifetimes was obtained for all the MPcs–GSH-AuNPs-linked conjugates compared to the MPcs alone. The highest triplet quantum yield of 0.75 and the longest triplet lifetime of 130 μs were obtained for the GeMCPc–GSH-AuNPs-linked conjugate. Fluorescence quantum yields and lifetimes were low for the conjugates due to quenching by the nanoparticles.

- Description: This study examines the nature and character of consensus and contentions around the discourse of community engagement in a South African university context. This is against the background of the growing body of literature that advocates for the need for universities to make their impact felt in communities in more direct ways than through teaching and research. The examination is also against the background of the assumption that the success or failure of community engagement initiatives is, in part, a function of how stakeholders agree/disagree on the meaning and purpose of community engagement. The University of Fort Hare is used as a case study. Interviews and Focus Group Discussions were used for qualitative data collection, whilst a survey was conducted for gathering quantitative data. The study revealed that stakeholders attach different meanings to community engagement, with those possessing power and influence acting as key decision makers. Thus powerful stakeholders (in this case, the university and donor organizations) are at the core of the decision making process, while beneficiaries are pushed to the periphery. Moreover, both the meanings and the activities within which they cohere have important implications for the way beneficiary communities perceive university-community partnerships.

Constitutional damages for the infringement of a social assistance right in South Africa are monetary damages in the form of interest a just and equitable remedy for breach of a social assistance right

- Description: This dissertation will explore the revolutionary progression in the provision of monetary damages and the availability thereof due to the change in South Africa’s legal system from Parliamentary sovereignty to Constitutional supremacy after the enactment of the final Constitution in 19961. The Constitution of South Africa brought with it the concepts of justification and accountability as the Bill of Rights enshrines fundamental rights and the remedies for the infringement of same. The available remedies for the infringement of a fundamental right flow from two sources, being either from the development of the common law remedies in line with the Bill of Rights or alternatively from Section 38 of the Constitution, which provides for a remedy which provides ‘appropriate’ relief. The question that will be raised in this dissertation is, ‘does appropriate relief include an award of delictual damages?’ or a question related thereto ‘is an award of monetary damages an appropriate remedy?’ The motivation for this dissertation arises from the plethora of case law, especially in the Eastern Cape, that has come to the fore in the last sixteen years, highlighting the injustice of cancellations of social assistance grants and the non-payment of such in South Africa’s social security system, as well as the precedent that was set by our Constitutional Court and Supreme Court in remedying that injustice. The central case to this dissertation is that of Kate v Member of Executive Council for Department of Welfare, Eastern Cape 2005 1 SA 141 SECLD; Member of Executive Council, Department of Welfare, Eastern Cape v Kate 2006 (4) SA 478 (SCA), which is generally regarded as having paved the way for the granting of monetary damages for the infringement of an individual’s constitutional right as same require legal protection. Firstly the past approach to damages will be explored in relation to South Africa’s common law, being the Roman-Dutch law. The common law Aquilian action is the focal point of this dissertation in relation to the common law in that the granting of damages for the infringement of an individual’s social assistance right (being a specific constitutional right framed within the 1996 Constitution) results in pure patrimonial loss which in our common law system was remedied by the actio legis Aquilae. In delict, an award of damages is the primary remedy, aimed at affording compensation in respect of the legal right or interest infringed. After the common law system of damages has been explored, this dissertation will then examine the changes that have developed therefrom, and largely shaped by the current state of disorganization in the National Department of Welfare coupled with the all encompassing power of the final Constitution. The final Constitution provides the power, in section 38 of the 1996 Constitution, for the court to award a monetary remedy for the breach of a constitutional right. The question, however, is “does the award of monetary damages not merely throw money at the problem, whereas the purpose of a constitutional remedy is to vindicate guaranteed rights and prevent or deter future violations?” The battle for domination between the common law approach and the constitutional approach to damages is witnessed as the two systems eventually amalgamate to form an essentially new remedy, unique to South Africa. South Africa’s new system is aligned with the Constitution as the Constitution is the supreme law of the land and underpins the awarding of all damages and, especially, the awarding of constitutional damages. For the sake of completeness, alternatives to monetary damages will also be canvassed in this dissertation. It is hoped that the reader will, in the end, realize that the final Constitution is the supreme law of the land and as such dictates the manner and form in which damages are provided. If such provision is not in alignment with the Constitution, it will be declared invalid. The flexibility of our common law is put to the test, yet it is found to be adaptable to the ever-developing boni mores of society exemplified in the embracing constitutional principles and the production of this new remedy. The courts develop the common law under section 39(2) of the Constitution in order to keep the common law in step with the evolution of our society and the ever changing nature of bonos mores. , National Research Foundation

- Description: The Earth's health is deteriorating and will deteriorate even more rapidly unless people adopt eco-friendly policies. Green building has long been a concept but it has not yet been universally applied in practice. The concept of sustainability emerged in the 1970s and can be associated with the energy crisis and environmental pollution concerns. This research is aimed at investigating whether building “green” is more demanding than non-green buildings in terms of cost and the use of green materials against traditional materials; whether professionals in the construction industry are knowledgeable in terms of green buildings; and lastly, to determine whether green buildings are contributing significantly to the environment. The literature reviewed and results of quantitative research amongst professionals from the Island of Mauritius formed the basis of the study. The study revealed that green building is expensive relative to traditional buildings considering. However, the concepts employed (for example: lower energy use, less waste disposal, lower water usage, and sustainable design) provide green buildings with long term savings. Furthermore, the scarcity of natural materials makes it expensive. The study also showed that contractors and professionals have a preference for traditional materials over green materials thus making them more familiar with traditional materials. Contractors and professionals are believed to understand green materials only on a limited basis. This may be attributed to the specific environmental issues involved; however, the research revealed that the professionals are familiar with the basic concepts of green buildings. Lastly, the research showed that green building is still at its infancy but the benefits of green buildings are understood; resulting in green buildings having a good growth potential. The study should be valuable to construction industry professional and clients.

- Description: This research investigates the consumer perceptions of private label brands amongst the university aged consumers from selected Eastern Cape universities. The research also aimed to ascertain whether or not generation Y consumers are aware of the existence of private labels, whether price, quality, advertising, packaging, reference groups and demographic variables influenced generation Y purchasing behavior of private label brands. To achieve these objectives, the research made use of the simple random technique to gather the primary data via the use of an online structured questionnaire. The sample population selected where the students in the Eastern Cape Province Universities (Rhodes and Nelson Mandela Metropolitan Universities) who reside off-campus. The assumption was that students who reside off-campus are more aware of private labels as they carry out shopping more than those that reside on campus and generally would have more disposable income and the reason that two different universities have been chosen is to provide a broad base of student opinions, covering varying cultural and income backgrounds, thus allowing for unbiased, valuable research. After pre-tests were conducted the questionnaire was made available online to easy the distribution of the questionnaire and allow for a greater response rate. Descriptive and inferential statistics where used to analyze the results of the questionnaire. The results showed that consumers are generally aware of private label brands and have at least seen them being advertised. Furthermore, the results showed that consumers purchase groceries based on price, quality and convenience of location of the grocery stores .The results indicate that Generation Y consumers are indeed a significant part of the consumer population and that they represent a confident, self reliant, optimistic and positive generation and are verbally and visually more sophisticated, creating a whole new language through digital media and that Generation Y consumers are generally aware of the existence of private labels. The results also indicate that Generation Y consumers strongly agreed that they purchase groceries based on price and quality, meaning price and quality are very influential when purchasing groceries and that the packaging of, generally, all private label brands was not attractive hence a conclusion was made that packaging of private labeled products does not influence Generation Y’s purchasing behaviour of private labels.

- Description: Family businesses are operating throughout the world and suggested to be the predominant way of doing business. This is also true in South Africa with its unique challenges and informal sector providing work to many South Africans not able to find work in the formal sector. Women operating in the corporate environment have traditionally encountered challenges in breaking through the glass ceiling in order to be counted as a successful person in her own right. The same scenario seems to be evident in the family Business environment. Women in family business might choose the family business career path as it allows them more flexibility and time to attend to the home and children, but they also face a glass ceiling of another nature and are there other challenges to overcome in order to make their mark in the family business world. This study’s primary objective was to investigate the literature pertaining to women in business and women in family business. Of great importance was to determine what contributions women make in the family business environment allowing them to be successful. In order to answer this question the secondary objectives supported the primary objective of this study and pertained to the difference between men and women in terms of leadership style and execution of their personalities in business. The inherent strengths and weaknesses displayed by both male and females in the family business environment are investigated in order to link this to their management execution. v A questionnaire was developed to do an empirical study on respondents as identified in the Nelson Mandela Metropole and greater Eastern Cape. The respondents were from varied industries and was selected and interviewed with the support of the questionnaire structure as guidance. The results were analysed and certain recommendations were made addressing the primary objective. Further recommendations were made relating to future potential research in this area. An important finding of the research is that women as identified in the Eastern Cape environment still have difficulty in reaching the top. This is true for the corporate world as well as the family business environment. The difficulty might be based in the traditional roles women assume, but in many cases it was found that women are responsible for their downfall or stagnation in the family business environment as women are satisfied to remain in the shadows and do not command their own space and right of existence. Recommendations were made based on the advice of some of the female respondents which can assist in women stepping up to the role they should take up. Some of the advice given can be used as a best practice in future research of this nature.

- Description: This treatise represents an investigation into the coping strategies of female Zimbabwean refugees at the Central Methodist Church (CMC) in Johannesburg. The CMC in Johannesburg includes a non-profit organisation called Ray of Hope that has functioned as a provider of accommodation and emergency refuge at the church since 1997. A vast number of Zimbabweans are moving to adjacent countries as a consequence of the conflict in Zimbabwe and approximately 85 percent of the people that have sought refuge in the CMC in Johannesburg are Zimbabweans that have fled the economic and political conflict in Zimbabwe. Using an interviewing strategy of a sample of 20 female Zimbabwean refugees, conducted at the CMC, the researcher gathered data, indicating that they face various conflicts on a daily basis inside as well as outside the refugee community in the CMC in Johannesburg. An extensive literature review and researcher‟s own observations during hours spent in the refugee community have also contributed to the collection of data. The findings suggest that coping mechanisms have been adopted by the female refugees to deal with the conflicts. Analysis of data was guided by grounded theory approach which allowed key findings about coping mechanisms to surface which encouraged recommendations presented in the conclusion of the treatise.

- Description: This treatise represents an investigation into the coping strategies of female Zimbabwean refugees at the Central Methodist Church (CMC) in Johannesburg. The CMC in Johannesburg includes a non-profit organisation called Ray of Hope that has functioned as a provider of accommodation and emergency refuge at the church since 1997. A vast number of Zimbabweans are moving to adjacent countries as a consequence of the conflict in Zimbabwe and approximately 85 percent of the people that have sought refuge in the CMC in Johannesburg are Zimbabweans that have fled the economic and political conflict in Zimbabwe. Using an interviewing strategy of a sample of 20 female Zimbabwean refugees, conducted at the CMC, the researcher gathered data, indicating that they face various conflicts on a daily basis inside as well as outside the refugee community in the CMC in Johannesburg. An extensive literature review and researcher‟s own observations during hours spent in the refugee community have also contributed to the collection of data.

- Description: Core Self-Evaluations [CSE] are a person’s estimation of his/her own worth and ability (Judge & Scott 2009). This in turn, is related to Racial Evaluation which is a person’s internal evaluation of his/her racial identity (Diller, 2010). The Employment Equity Act (55 of 1998) makes provision for the employment of equity candidates who can acquire skills in a reasonable amount of time. This requires individuals to be able to learn and then achieve in outcomes-based assessment. Core Self-Evaluations and Racial Evaluation can have an impact on how individuals perceive themselves, and how they perform in education, training and development (Hanley & Noblit, 2009). This study explored the relationship between Core Self-Evaluation, Racial Evaluation, Learning and Outcomes-Based Assessment using an experimental design. The Core Self-Evaluation scores in this study (n=230) were consistent with levels found internationally (Broucek, 2005). There was positive Racial Evaluation, with a relationship existing between Racial Evaluation and Core Self-Evaluations. This means that part of a person’s identity as an individual is related to Racial Evaluation, with that Racial Evaluation being positive amongst young Zulu students at the University of Zululand. There was a statistically significant, but small correlation between Learning and Core Self- Evaluation and a relationship was also found between CSE and Outcomes-Based Assessment results. When Core Self-Evaluation is higher, Learning tends to be more likely. The same pattern does not hold for Outcomes-Based Assessment results. Among Zulu students, lower CSE is linked to improved Outcomes-Based Assessment results. Racial Evaluation has a small relationship with CSE. However, efforts to remedy apartheid may be directed towards socio-economic development and need not focus on boosting Racial Evaluation when it comes to young Zulu adults.

- Description: Low cover crop biomass production is a major obstacle to the success of conservation agriculture currently promoted as panacea to the inherent problem of soil erosion and loss of soil productivity in the Eastern Cape (EC). Therefore, this study evaluated cover crop management strategies for optimizing biomass production for better soil cover, soil nitrogen (N) and phosphorus (P) fertility, weed control and maize yields. The strategies tested are cover crop bicultures, selection of an adapted lupin cultivar and seeding rate, and the feasibility of rain fed winter cover cropping. The cover crop experiments were carried in rotation with summer maize between the winter of 2009 and summer of 2010/2011. Biculture trial was carried out by seeding oat (Avena sativa) and vetch (Vicia dasycarpa) at three mixture ratios and as sole crops under irrigation. On a separate irrigated trial, two lupin cultivars (Lupinus angustifolius var Mandelup & Qualinock) were seeded to a range of seeding rate, 40 to 220 kg ha-1. To study the feasibility of rain fed winter cover cropping, oat, vetch, rye (Lolium multiflorum), barley (Hordeum vulgare), radish (Raphanus sativa) and triticale (Triticale secale) were relayed into a maize crop in February, March and April of 2010. The irrigated trials were followed with SC701 maize cultivar, whilst the rain fed trial was followed with DKC61-25 maize cultivar. Bicultures gave higher cover crop biomass than sole vetch, increasing with an increase in the oat component of the mixture. Increased N and P uptake was observed with bicultures compared to sole oat, however, the levels were comparable to sole vetch. Sole vetch increased soil inorganic N and P at maize planting, whilst the slow decomposition by sole oat residue resulted in mineral lock up. Bicultured cover crop residues had intermediate decomposition rates and resulted in optimum levels of inorganic N and P for prolonged periods compared to sole crops. Weed suppression by the bicultures was comparable to sole cover crops. Biculturing technology significantly (P<0.05) increased maize grain yield compared to sole oat and the yields were comparable to those from sole vetch. For lupins, 206 kg ha-1 seeding rate gave the optimum biomass yield. Weed dry weights in both cover crop and maize crop decreased with an increase in lupin biomass. Comparable soil total N and inorganic P values at maize planting, were observed from plots planted to 120, 180 and 220 kg ha-1. Maize grain yield increased with an increase in lupin seeding rate. The study on rain fed winter cover cropping had most cover crop species’ biomass decreasing with each delay in planting except for radish, which increased. Vetch produced the highest amounts of biomass from February and March planting whilst radish had the highest biomass in April planting. The two species resulted in the greatest N improvement compared to the other species. Regardless of the grazing, the grass specie residues managed to persist to the next cropping season and the residue remaining were comparable to that of radish and vetch. Late-planted cover crops had the greatest residue remaining than early-planted, as a result, April planted cover crops provided better weed suppression than March and April planted. Vetch provided the highest maize grain yield (4005 kg ha-1) whilst all other species tested had comparable grain yields. The results suggested that bicultures could be grown to give sufficient biomass for both weed suppression and soil fertility improvement. Furthermore, increasing lupin plant densities improve its function as a cover crop with respect to weed suppression, soil fertility improvement and maize yields. The study also showed that for dry land systems, February and March planted vetch and April planted radish can provide the greatest biomass and maize yield improvement.

Crime, violence and apartheid in selected works of Richard Wright and Athol Fugard: a study

- Description: Different forms of racial segregation have been practiced in different countries the world over. However, the nature of South Africa‟s apartheid system, as it was practiced from 1948 until the dawn of the democratic dispensation in 1994, has been a subject of debate in South Africa and even beyond. Apartheid was a policy that was designed by the then ruling Nationalist Party for purposes of dividing and stratifying South Africa along racial lines - whites, blacks, coloureds and Asians. It thus promoted racial segregation and/or unequal stratification of society. In South Africa‟s hierarchy of apartheid, blacks, who constituted the majority of the population, were ironically the most destitute and segregated. Some historians believe that South Africa‟s racial policy was designed against the backdrop of Jim Crow, a similar system of racial discrimination which was instituted in the American South late in the 1890s through the 20th century. Jim Crow and apartheid are, in this study, considered as sides of the same coin; hence for the sake of convenience, the word apartheid is used to subsume Jim Crow. Although South Africa‟s apartheid system was influenced by different ideologies, for example German missiology as applied by the Dutch Reformed Church, historian Hermann Giliomee (2003: 373) insists that „the segregationist practice of the American South was particularly influential.‟ Given the ideological relationship between apartheid and Jim Crow, the present study investigates the interplay of compatibility between apartheid/Jim Crow and crime and violence as reflected in selected works of Richard Wright (African American novelist) and Athol Fugard (South African playwright). The aim of the study is firstly, to examine the works in order to analyse them as responses to apartheid and by extension colonial domination and secondly to investigate crime and violence. The three criminological theories selected for this study are strain theory (by Robert Merton), subculture theory (Edwin Sutherland) and labelling theory (Howard Becker). While criminological theory provides an empirical dimension to the study, postcolonial theory situates the study within a specified space, which is the postcolonial context. The postcolonial is, however understood, not as a demarcated historical space, but as a continuum, from the dawn of colonization to the unforeseeable future. Three postcolonial theorists have been identified for the purposes of this study. These are: Frantz Fanon, Homi Bhabha and Bill Ashcroft. Fanon‟s psychoanalysis of the colonized, Homi Bhabha‟s Third Space and hybridity as well as Ashcroft‟s postcolonial transformation are key concepts in understanding the different ways in which the colonized deal with the consequences of colonization. It has been suggested particularly in Edward Said‟s Orientalism (1978) that the discourse of orientalism creates the Oriental, as if Orientals were a passive object of the colonial adventure. This study uses Bhabha‟s and Ashcroft‟s theory of colonial discourse to argue that the colonized are not only objects of the colonial enterprise but also active participants in the process of opening survival spaces for self-realization. The various criminal activities that the colonized engage in (as represented in the selected works of Richard Wright and Athol Fugard) are in this study viewed as ways of inscribing their subjectivity within an exclusive colonial system.

- Description: The concept of cross-border tourism planning and cooperation is investigated in reference to the Lake !Gariep Initiative. The field of cross-border economic planning and integration is an area of increasing interest in regional development studies. The Lake Gariep Initiative is an initiative to promote cross-border planning and development around nature conservation, water resource management, economic development, poverty alleviation and tourism in the three municipalities that surround the Gariep Dam. The Gariep Dam, which is largest dam in South Africa, is surrounded by three provinces. The region is also economically and politically marginalised as it has a small, dispersed population and a marginal contribution to the broader regional economy. Under these circumstances the coordination of resources between municipalities to develop and promote the region has been identified as a key success factor for the region. The Lake Gariep Initiative although strongly supported locally has over ten years failed to be institutionalised. This study examines the Lake Gariep Initiative in terms of the origins of the concept and the key challenges that have been faced in establishing a cross-border, development entity. Findings are based on an assessment of documents on the formation of the LGI, interviews with stakeholders involved in the process and an assessment of critical success factors in reference to national and international case studies. This study provides a review of the key challenges, benefits and critical success factors for cross-border tourism development in relation to the Lake !Gariep Initiative.

- Description: The topic of interpersonal relationships and the factors that enhance the longevity and strength of these have been well documented. Whilst there has been a steady increase in the occurrence of interracial relationships, it has not been matched by an increase in studies on the phenomenon and indeed very little empirical attention has been given to these relationships. Leslie and Letiecq (2004) highlight that the existing research on the phenomenon focuses primarily on the reasons individuals select partners outside of their own racial group. As interracial marriages are reportedly more vulnerable to divorce than marriages among same-race individuals, it seems important to examine the dynamics and quality of interracial relationships (Leslie & Letiecq, 2004). The goal of the study was therefore to explore the cross-cultural differences that inform the experiences, challenges, and strengths for partners in committed interracial relationships. In this qualitative, exploratory, descriptive and contextual study, the author has explored and described the specific cross-cultural differences that the couple has encountered in their relationship and the impact that these differences have had on the quality of their relationship. Furthermore the study aimed to explore and describe the strengths the couple has drawn from these cross-cultural differences to enhance the quality of their relationship. A combination of purposive and snowball sampling techniques has been utilised to identify interracial couples who have been in a committed monogamous relationship of at least one year. The sample consisted of eleven individuals. Semi-structured individual interviews were utilised as the data collection tool, and Tesch‟s model of data analysis (in Creswell, 1998) has been employed. This model of data analysis consists of eight steps that have been used to analyse the data. Five themes emerged from the study: (1) cultural difference factors, (2) negative factors that influence the couple‟s coping with cultural differences, (3) positive factors that influence the couple‟s coping with cultural differences, (4) factors relating to cultural differences that strengthen the relationship and (5) recommendations to other interracial couples. The findings of the study make a meaningful contribution to couple counselling interventions for interracial couples, and also add to the body of knowledge on this sparsely researched topic.

- Description: There is an increasing awareness that monetary value does not fully represent the complete value and significance of NTFPs. Consequently, there is growing interest in the cultural dimensions of biodiversity and the role that it plays in human well-being. This chapter presents two case studies, one on traditional brooms in South Africa, and the other on amate paper in Mexico, to demonstrate the importance of cultural values on driving demand for NTFPs. Because cultural values are so deeply embedded, the demand for culturally valued NTFPs continue across the rural-urban divide, and are maintained even by modernising urban communities. This poses particular challenges, not only for conservation of the NTFPs, but also to sustain cultural diversity in a rapidly changing world.

- Description: There is an increasing awareness that monetary value does not fully represent the complete value and significance of NTFPs. Consequently, there is growing interest in the cultural dimensions of biodiversity and the role that it plays in human well-being. This chapter presents two case studies, one on traditional brooms in South Africa, and the other on amate paper in Mexico, to demonstrate the importance of cultural values on driving demand for NTFPs. Because cultural values are so deeply embedded, the demand for culturally valued NTFPs continue across the rural-urban divide, and are maintained even by modernising urban communities. This poses particular challenges, not only for conservation of the NTFPs, but also to sustain cultural diversity in a rapidly changing world.

- Description: The notion of ‘culture’ features in the abortion literature to explicate, first, contestation of the meaning of abortion (as in the ‘culture wars’ about abortion), second, the normalisation of abortion in certain countries (as in ‘abortion culture’), third, the response of women to abortion within a particular social milieu and fourth, cross-cultural variability in attitudes towards and experiences of abortion. What is missing is an exploration of how ‘culture’ may be deployed as a discursive resource to oppose legal abortion. In this article, we report on a study conducted in a rural area of South Africa. We conducted focus group discussions utilising hypothetical vignettes to stimulate talk. Although, inconsistencies were evident in participants’ talk, in the context of cultural discussions, abortion was constructed as killing and inevitably destructive of cultural values and traditions. Abortion was equated with colonialist interventions and as something that should be opposed in the preservation of culture. Furthermore, cultural opposition to abortion was rooted in fears around the breakdown of gendered and generational power relations. Examples of how culture may be used in everyday interactions to induce shame and negative experiences are also discussed.

Curating the reviled, beloved and quotidian: a retrospective of Vladimir Tretchikoff

- Description: This thesis aims to contextualise my curation of 'Tretchikoff: The People's Painter' at the Iziko South African National Gallery by outlining the process by which I came to embark on this project and to examine the concepts of mass art and kitsch in relation to the painter. Mass art, in Noel Carroll's explication of the term, is art that utilises industrial processes of replication. Carroll argues that this leads to specific formal and structural tendencies in this art which have much in common with the pejorative concept of kitsch, or art that is lacking in taste or effuses excessive emotion. The latter term was and continues to be applied to Tretchikoff. Although some have attempted to 'reclaim' the word as a positive concept the negative associations that link this term to Tretchikoff are strong. Interrogating these concepts led me to decide to curate TretchikofPs retrospective by focusing on his painting and not including the prints for which he was so well known. Awareness of the complex associations and 'received knowledge' that his prints engender has influenced several curatorial decisions that I have taken. I consider the intellectual underpinnings of my curatorial strategy and argue for an 'open' exhibition which gives the viewer the opportunity to assess his work and legacy in an objective manner, free from as much curatorial mediation and didacticsm as possible. There are no answers to be offered in my curation of Tretchikxiff the People's Painter, rather I have aimed to set up dialogues, discussions, confrontations and challenges; I have offered simple relationships rather than complex juxtapositions I have aimed to position the artwork as the centre of the engagement relative to the viewer.

- Description: Customer relationship management (CRM) presents a new paradigm shift to the old traditional marketing strategies that are known and practiced by many organisations in South Africa and across the globe. Competition is not an excuse for failure anymore. Organisations that do not have any concrete strategies in dealing with the customer will not survive in the market. The ultimate goal of CRM is to enable organisations to forge closer ties with the customer so that a solid bond can be created to enhance loyalty and satisfaction. The goal for this research was to identify the CRM strategies used by a single organisation and thereafter suggest improvements to enhance customer loyalty. The results of the study could assist the management of the organisation to improve the CRM strategies which will hopefully enhance retention and prevent customer attrition. A literature review was conducted to unveil various elements of CRM, and strategies that can attract and retain customers. It helped in identifying themes for the empirical study. An in-depth interview was conducted with the general manager of the organisation to gauge his perception, and CRM practices in the organisation. An interview guide was used during the interview process. Four main topics namely: implementation of CRM, customer loyalty, customer complaints and conflict, and employees training and motivation were utilised for the interview guide and followed by further probing. Based on the responses obtained, analyses were made by comparing the responses to what literature revealed so that shortcomings could easily be identified.The study revealed that there were several inconsistencies with what was practised by the organisation and what the literature study revealed. Bearing in mind the shortcomings identified in the empirical study, the researcher made the following recommendations. The CRM implementation approach needs to be carefully planned with a clear defined vision and mission statement that focus on customer centredness. The organisation needs to invest in modern and innovative channels of communication and strategic partnership to reach the right customer. The organisation has to develop effective market segmentation and targeting to know the customer well. Consistent and highly relevant customer experiences should be drawn-on to fulfill the organisation’s promise of trust and reliability. The organisation should adopt competitive pricing strategy to limit customer sensitivity on price. The organisation should invest in employees’ development and welfare. Further research can be conducted to investigate the perception of other food retailers on the CRM strategies practiced. Further research can also be conducted in the organisation to investigate the perception of employees and customers on the CRM strategies practised.

- Description: We report here on the synthesis of a new manganese phthalocyanine complex, namely Mn tetrakis(5-hexyn-oxy) phthalocyanine (3), specifically designed to possess an alkyne moiety for its potential use in controlled immobilization on electrodes via the so called “click” chemistry reaction. The electrochemical activity of complex 3 was investigated by cyclic voltammetry and the nature of the observed redox couples was elucidated by spectroelectrochemistry. This work has also shown that the reduction of Mn(III)Pc complex to Mn(II)Pc is accompanied by the formation of MnPc μ-oxo species. Further reduction results in the formation of Mn(II)Pc(− 3) rather than Mn(I)Pc(− 2).

- Description: Video oriented services are taking the lead in terms of revenue in the current Internet environment. In order to tap this revenue, Telcos are resorting to serious measures such as moving to Next Generation Network (NGN) where they can provide QoS for services that demand this feature, such as, IPTV. IPTV is more than just what its name implies and includes various types of additional services to make the TV a better entertainment and communication environment. Various innovative IPTV services have been proposed and developed by researchers and practitioners, including personalized advertisement, personalized EPG (Electronic Program Guide), and personalized VoD (Video on Demand). In this paper we introduce a new IPTV service called, the personalized dynamic video delivery service, which sends new video alerts (like breaking news alert) to subscribed users and notifies them when the video is available. If desired, users can watch the video automatically by switching from what they are currently watching without requiring explicitly a new video setup. Users can configure their profile and also set a policy on the way they wish to be notified and the types of video they wish to be alerted to. The paper describes the issues surrounding the delivery of this service and presents the architecture and the various open source technologies that are used to develop the service.

- Description: This study used integration as the overarching conceptual framework to investigate socio-spatial integration in post-apartheid South Africa. The study adopted the embedded case study design to investigate the spatial and social aspects of integration in former white residential suburbs in East London, South Africa. Recognising that integration occurred in different registers, this study used data from the South African Property Transfer Guide (SAPTG) database to investigate spatial-temporal integration in East London‟s residential suburbs from 1993 to 2008. A total of 21,683 residential property transfers were reviewed in 46 suburbs, and transfers to Blacks were identified. The residential property transfers were mapped to identify the nature of spatial integration. To investigate social integration, in-depth personal interviews were conducted on a purposively drawn sample of residents in the three case study suburbs of Southernwood, Cambridge and Gonubie. The interviews focused on three proxy indicators of social capital at neighbourhood level. The results of the study showed that post-apartheid spatial integration in East London closely followed the class-based residential template. Contrary to predictions prior to, and following apartheid‟s demise, the study showed that spatial integration occurred without racial conflicts. The study also found that social integration in the residential suburbs reflected the neighbourhood context and personal preferences, and was highly fluid. Although feelings of racial distance were evident, there were also indications of social cohesion, which were dynamic and uneven in time and space. Based on the data and the dialectical nature of spatial and social integration, the study concluded that fragmentation and integration are likely to continue coexisting in the South African city.
