  • Description: This paper seeks to understand the relationship between the intellectualisation of African languages and the facilitation of a research approach which will enhance this intellectualisation. The paper examines the legislative language policies and other documents published by government since 1994, which guide language use and practices in higher education, including the Catalytic Project on Concept Formation in indigenous African languages (one of the recommendations contained in the Report commissioned by the Minister of Higher Education for the Charter for Humanities and Social Sciences and the language clauses of the Green Paper for Post-Secondary School Education and Training). These policy documents are analysed against the backdrop of the research work of the newly initiated NRF SARChI Chair in the Intellectualisation of African Languages, Multilingualism and Education hosted by Rhodes University. The paper argues that while policy provides an enabling environment for the promotion and development of indigenous African languages and advocates for promotion of equity and equality, in actual fact, HEIs still grapple in implementing provisions of these policies. The paper further discusses the teaching, learning and research in the African Language Studies Section of the School of Languages at Rhodes University and how the Section adopted the provisions of the national policy and institutional policy on language in turning itself into a source of intellectual vitality in the teaching, learning and research of particularly isiXhosa. Six focus areas of research, linked to the NRF SARChI Chair, will be outlined in order to create a practical link between Policy, Implementation and the Intellectualisation of African Languages. , Ucwaningo lolu luhlose ukuqonda ubudlelwano obuphakathi kokusetshenziswa kwezilimi zesintu emazingeni aphakame kanye nokusetshenziswa kwendlela yocwaningo ezokwengeza amathuba okusetshenziswa kwezilimi lezi (Finlayson & Madiba 2002).

  • Description: This study investigates the interaction between stock market and macroeconomic variables in South Africa. Apart from the stock market being a channel to raise capital, another important role of the stock market is to provide correct valuation of stocks and promote efficient allocation of capital. This is important given the great need of investment capital in a country such as South Africa. Utilising quarterly data for the period from 1994 to 2012, the study employs the Johansen cointegration test and the Vector Error Correction Model (VECM) to analyse the relationship between these important variables due to the simultaneous nature of the relationship between the variables. Empirical results indicate that all the variables have a significant relationship with the stock market. The findings in this study suggest that it is important to achieve macroeconomic equilibrium in South Africa because any disequilibrium in macroeconomics feeds into the stock market and it is likely to affect investor decision making and hence access to capital by companies listed on the stock exchange.

  • Description: The advent of advanced modern nanotechnology techniques offers new and exciting opportunities to develop novel nanotech-derived antimalarial nanodrugs with enhanced selective and targeting abilities that allow for lower effective drug dosages, longer drug persistence and reduced drug degradation within the body. Using a nanodrug approach also has the advantage of avoiding drug resistance problems that plague reconfigured versions of already-existing antimalarial drugs. In this study recombinant triosephosphate isomerase enzymes from Plasmodium falciparum (PfTIM) and Humans (hTIM) were recombinantly expressed, purified and characterised. PfTIM was shown to have optimal pH stability at pH 5.0-5.5 and thermal stability at 25°C with Km 4.34 mM and Vmax 0.876 μmol.ml⁻ₑmin⁻ₑ. For hTIM, these parameters were as follows: pH optima of 6.5-7.0; temperature optima of 30°C, with Km 2.27 mM and Vmax 0.714 μmol.ml⁻ₑmin⁻ₑ. Recombinant TIM enzymes were subjected to inhibition studies using polyvinylpyrrolidone (PVP) stabilised silver nanoparticles (AgNPs) of 4-12 nm in diameter. These studies showed that the AgNPs were able to selectively inhibit PfTIM over hTIM with an 8-fold greater decrease in enzymatic efficiency (Kcat/Km) observed for PfTIM, as compared to hTIM, for kinetics tests done using 0.06 μM of AgNPs. Complete inhibition of PfTIM under optimal conditions was achieved using 0.25 μM AgNPs after 45 minutes while hTIM maintained approximately 31% of its activity at this AgNP concentration. The above results indicate that selective enzymatic targeting of the important, key metabolic enzyme TIM, can be achieved using nanotechnology-derived nanodrugs. It was demonstrated that the key structural differences, between the two enzyme variants, were significant enough to create unique characteristics for each TIM variant, thereby allowing for selective enzyme targeting using AgNPs. If these AgNPs could be coupled with a nanotechnology-derived, targeted localization mechanism – possibly using apoferritin to deliver the AgNPs to infected erythrocytes (Burns and Pollock, 2008) – then such an approach could offer new opportunities for the development of viable antimalarial nanodrugs. For this to be achieved further research into several key areas will be required, including nanoparticle toxicity, drug localization and testing the lethality of the system on live parasite cultures.

  • Description: Both historiographical and literary practices have undergone revision in recent years in attempting to address the inheritance of nineteenth-century realism. Since the object of realist stylistics, employed in both the writing of fiction and history, is to render authorship authoritative or even invisible, the ideological import of these narratives is often such that the constructedness of the historical record and its absences are veiled. In developments beginning in the 1980s with the advent of ‘New Historicism’ and with the emergence of postmodern literary techniques, the interface of literature and history became of seminal importance, since both were now credited as being products of narrative and discourse, and hence, to varying degrees, of the literary imagination. This movement intersects interestingly with developments in postcolonial studies, since it is the voices of the marginalized and disempowered colonized peoples that are routinely co-opted and excised from nineteenth-century realist histories. These concerns are now being fully explored in the literature of the contemporary post-transitional South African moment, since authors in this country seemingly now feel freed up to look back to histories that precede the immediate traumas of apartheid. The concern, in relation to apartheid developments but also on a broader universal scale, is this: if history is viewed as perpetual emergences of modernities, then one of the great absences in the record is the historical determinants of any given epistemology. The attempt to recreate such an epistemological genealogy is thus simultaneously postcolonial, historiographical, and literary. Russel Brownlee’s Garden of the Plagues (2005), Ingrid Winterbach’s To Hell with Cronjé (2010), and Etienne van Heerden’s The Long Silence of Mario Salviati (2002) attempt to bridge this gap in the recorded sensibilities of any historical moment by representing a ‘lived experience’ of the past, and in the process imaginatively recreating the cultural, historical and psychological locations of the proponents of an emerging modernity. This study concerns itself with the ways in which these authors address the influence of realist historiography through the use of literary innovations that allow for the departure from realist stylistics. Most commonly, all three authors draw on forms of magic realism, but multiple refigurings and recombinations of notions of temporality, narrative, and characterization likewise work to defamiliarize the once stable discourse of history.

  • Description: STAT3 (signal transducer and activator of transcription 3), an oncogene and transcription factor of genes involved in cellular differentiation, proliferation and immune function, that classically localizes in the cytosol and nucleus has also been found in the mitochondria. However, STAT3 does not have a mitochondrial transit peptide, and its mechanism for mitochondrial localization is unknown. Cytosolic Hsp90s chaperone STAT3 to the nucleus therefore we investigated the involvement of the nuclear-encoded mitochondrial Hsp90 molecular chaperone tumor necrosis receptor associated protein 1 (TRAP1) in STAT3’s mitochondrial localization. Using TRAP1 transient over-expression, STAT3 inhibitor S3I- 201 and Hsp90 inhibitor geldanamycin, we demonstrate that TRAP1 and STAT3 co-localize and co-immunoprecipitates in mammalian systems. Taken together with the observation that STAT3 potentially directly interacts with TRAP1, these data suggest that TRAP1 plays a role in the mitochondrial localization of STAT3.

  • Description: The Kansanshi Cu-Au deposit located in the Domes region of the North West province of Zambia is characterised by structurally controlled high angle veins and associated alteration halos. The northwest trending Kansanshi antiform flanks the Solwezi syncline to the north and hosts the Kansanshi deposit and consists of tillites and metasedimentary rocks. Mineralisation is associated with Neoproterozoic Pan African deformation events experienced during the formation of the Lufilian fold belt; however recent findings confirm that structures in the form of reverse and normal faults and drag folds are critical controls on mineralisation within the deposit, Main pit in particular. Low angle faults occurring below the current pit are believed to have served as major fluid pathways during mineralisation. Age dating data from the Kansanshi deposit suggest that mineralisation took place between 512 and 503 Ma indicating that the event was associated with metamorphism. Two types of alteration are dominant within the Main pit (Kansanshi deposit) with the type and intensity of alteration being largely controlled by lithological units. Albite alteration occurs dominantly in phyllites and schists whereas dolomitisation is prevalent in calcareous units. Alteration is associated with mineralisation, and therefore is used as a condition for predicting vein or disseminated mineralisation. The high Au tenor at Kansanshi can be attributed to gold grains occurring in association with melonite (NiTe₂) and microfractured pyrite intergrown with chalcopyrite in sulphide and quartz dominated veins and veinlets. Analysis of gold grade distribution within the Main pit shows a clear concentration of the element along the major north-south trending structures like the 4800 and 5400 zones, possibly through supergene enrichment in the oxide-transition-sulphide zones. It is imperative that exploration for Kansanshi-type deposits will require geochemical and geophysical studies, understanding of the geology of an area to identify the three lithostratigraphic units (red beds, evaporites and reducing strata).

  • Description: Biofuels have been proposed to be a suitable replacement to the already depleting fossil fuels. The complex structures of plant biomasses present a challenge the production of biofuels due to recalcitrance. The complex cellulose structure and hydrogen bonding between repeat units of cellulose is believed to be a major contributor to the recalcitrance of cellulose. Fungal organisms come equipped with various oxidative enzymes involved in degradation of plant biomass. The exact mechanism of cellulose degradation remains elusive. The GH61 is a group of proteins which are PMOs. GH61 sequences where previously described as endoglucanases due to weak endoglucanase activity. These enzymes were later found not possess any enzyme activity of their own however they could enhance the activity of other cellulose degrading enzymes. As a result reclassification of these enzymes as AA9 has been implemented. AA9 proteins have been reported to share structural homology with the bacterial AA10 group of enzymes. Based on cleavage products that are produced when AA9 proteins interact with cellulose, AA9 proteins have been grouped into three types. To date the exact mechanism and the sequence and structural basis for differentiating between the various AA9 types remains unknown. Using various bionformatic techniques sequence and structural elements were identified for distinguishing between the AA9 types. A large dataset of sequences was obtained from the Pfam database from UNIPROT entries. Due to high divergence of AA9 sequences, a smaller dataset with the more divergent sequences removed was created. The inclusion of the reference sequences to the data set was done to observe which sequences belong to a certain type. Phylogenetic analysis was able to group AA9 proteins into three distinct groups. MSA and motif analysis revealed that the N-Terminus of these proteins is mostly responsible for type specificity. Structural analysis of AA9 PDB structures and homology models allowed the effect of physicochemical properties to be gauged structurally. The presence of 310 helices and aromatic residues the surface of AA9 sequences is an observation which still warrants further investigation.

  • Description: The effectiveness of leadership is largely dependent on whether the leadership competencies exhibited by leaders are congruent with the value system endorsed by subordinates. One of the ways in which leaders can influence subordinates is by understanding the leadership competencies valued by subordinates. Gender and national culture are two of the many factors that have an influence on the leadership competencies valued by subordinates. A large amount of research has been conducted to determine if, indeed, gender and national culture influence the leadership competencies subordinates' value. However, most of this research has been conducted in Europe and North America, places in which national cultures differ significantly from those prevailing in African countries. This study, from a South African and Zimbabwean perspective, attempted to ascertain if gender and national culture influence the leadership competencies they value in their leaders. Existing studies have indicated that gender and national culture do not influence the leadership competencies valued in a leader. The findings of this study are in accordance with previous research and agree that gender and national culture do not influence the leadership competencies valued in a leader. The results of this study indicated that male and female subordinates value similar leadership competencies. With respect to national culture, both South African and Zimbabwean subordinates value similar leadership competencies. Based on the findings of this study, regardless of gender and national culture, all subordinates value a leader who is loyal, visionary, openly embodies integrity, and is a leader who empowers subordinates.

  • Description: Pareuchaetes insulata (Walker) (Lepidoptera: Erebidae: Arctiinae) was released in KwaZulu-Natal, South Africa, as a biological control agent against Chromolaena odorata (L.) King and Robinson (Asteraceae) between 2001 and 2009. Although the moth did establish at one out of some 30 release sites, its population level is generally low in the field. Two closely related biological control agents, P. pseudoinsulata Rego Barros and P. aurata aurata (Butler) had previously failed to establish despite several years of releases. Studies of life history traits of P. insulata (males and females) were conducted to determine whether several aspects of its developmental and reproductive biology can explain its poor performance, and to compare the development and reproductive biology of P. insulata with the two other closely related species. At 25 °C, overall mortality of immature stages was generally low (below 12 %). Although the duration of the larval life stage was statistically longer for females, overall they eclosed as adults before the males (i.e. protogyny). Pupal mass, growth rate and total leaf area consumed were higher in females. Mated females laid 74% of their eggs on the first four nights following eclosion and lived an average of 5.92 ± 0.19 days. The moth also showed good biological attributes such as high fecundity (number of eggs), egg hatchability and female mating success (the number of matings that resulted in fertile eggs). Significant positive correlations were detected between insect performance metrics and leaf consumption and between fecundity and pupal mass. A 23 % greater lifetime reproductive output (387.62 ± 19.50 eggs per female) for P. insulata compared with P. aurata aurata was recorded. We hypothesize that the absence of protandry in P. insulata might have contributed to the low population levels of the moth in the field. The results of this study contribute to our understanding of the life history traits of erebid moths in the subfamily Arctiinae deployed for the biological control of C. odorata.

  • Description: The focus of this study was on the experiences of a small sample of local women who are HIVpositive and are living in poverty. The researcher was interested in exploring the psychological and social experiences of these women using Interpretive Phenomenological Analysis. This research aimed at giving these women a voice to express their first-hand, personal accounts of living with HIV in poverty. Data was analysed for meaningful units, which were interpreted inductively and hermeneutically, and categorised into super-ordinate themes. Six themes within the participants' experiences of living with HIV were determined, namely: (I) experiences of diagnosis, (2) disclosure experiences, (3) stigma, (4) ARV experiences, (5) experiences of social support and (6) poverty. This research found that after an HIV-positive diagnosis, most women experience a variety of emotional reactions. These reactions however seem to change overtime into positive acceptance of the HIV diagnosis. Most of the women in this study preferred to use partial disclosure than to fully disclose their HJV-positive status openly to families, friends and to their community. Reasons for not using full disclosure included fear of discrimination and stigma, which included a fear of being rejected or being blamed for their status and a fear of losing relationships. It was also evident from the findings that most of the women had experienced stigma directly and therefore partial disclosure was used as a coping mechanism to protect the self from further harm. It was also revealed that stigma not only has a negative impact on disclosure but also on social support and ARV experiences. Because ofHIV-related stigma, lack of social support was a struggle that almost all the women in this study had experienced. Lack of understandings about their medication also had a negative impact of the ARV experiences. Stigmas along with poverty are the major struggles that HIV -positive women have to deal with in their day to day living. The findings of this study reveal a need for further research in this experiential area as well as campaigns and education around issues such as stigma, medication, and emotional difficulties associated with HIV.

  • Description: The main research problem in this study was to identify strategies that could assist South Afrian companies in managing knowledge workers for their opt imal benefit . To achieve this goal, the following act ions were ta ken: Aliterature study was conducted to identify the best strategies that South African companies could use to manage knowledge workers for optimal benefit; Following the literature review interviews were concluded with key people in the human resource and recruitment industry to determine how a knowledge worker was defined in their organisations as well as to probe what management and human resources strategies were used to manage knowledge workers to their full potential; The interviews, in addition to the literature study, also served as a basis for a survey questionnaire, which was used to probe the views of knowledge workers to determine tools and strategies managers use to manage them. The empirical results from the study showed some concurrence with best strategies suggested from the theoret ical study. In essence, the study revealed that knowledge was well managed in the organisations where the study was conducted and that the knowledge workers were motivated and productive. However, it appeared that there was uncer tainty around the remuneration, rewards and recognition of these employees, which could ultimately reflect in less promising levels of commitment and lower levels of retention. The main findings were that: knowledge workers should be recognised for their good performance by providing financial incentives; knowledge workers should be provided with opportunities to continuously develop their competencies but be allowed to craft their own developmental experiences; knowledge workers should be empowered by delegat ing tasks to them that carry decision making responsibility and af fectinnovation; and Managers and knowledge workers should cont inuously have performance and organisational development discussions.

  • Description: This study sets out to investigate democratic participation in South Africa and the role that media play and can potentially play within this context. It considers a social movement, as one way in which citizens can organise themselves and make their voices heard to improve their chances of making a meaningful contribution to democracy. It employs Susan Bickford's theory of 'political listening', which offers a potential solution to the lack of political representativeness and inclusiveness, by focusing on the way citizens relate to each other through speaking, listening and dialogue. This study examines whether the interaction between learners and the social movement Equal Education could be considered 'political listening', and the current and possible role of the media within this context of participation. The study also attempts to develop and make a contribution to the language of description for the theory of political listening in order to map it onto the data. Using evidence or data gathered through observation of Equal Education's youth group meetings with learners and in-depth interviews with learners, youth group facilitators, Equal Education staff members and journalists, this study shows how the interaction amongst learners and between Equal Education and learners could be considered political listening and how the social movement works as a democratic project which offers learners an opportunity to exercise their citizenship. Furthermore, it also details the current role of the media and possible role of the media as perceived by Equal Education, learners and by journalists who report on Equal Education's activities. The study does not make conclusive claims about whether 'political listening' occurs between Equal Education and learners and the media because the study is exploratory in nature and involves a lot of trial and error when it comes to applying the theory of political listening to interview and textual data, which is a communication context that the theory is only beginning to chart.

  • Description: Globally, inshore cetaceans are being threatened by a number of anthropogenic activities. The Indo-Pacific humpback dolphin, Sousa chinensis, is currently listed as ‘near threatened’ by the International Union for the Conservation of Nature (IUCN). In order to be able to advise on management and conservation strategies, knowledge on the life history of the species is required. To date very little is known about the biology of humpback dolphins. The aim of the present study was to determine basic life history parameters, including age, growth and reproduction of humpback dolphins incidentally caught in shark nets. Age was estimated by counting the growth layer groups (GLGs) in the dentine and cementum of sectioned and stained teeth. Both a Von Bertalanffy and a Gompertz growth curve fitted well to the data, but for comparison with previous studies on Sousa, the Gompertz growth function was adopted to describe the relationship between length and age for KwaZulu-Natal populations. Length at birth was estimated between 104.33 and 111.57 cm for males and females, respectively. Asymptotic length was reached at 266.48 cm and 239.29 cm for males and females, respectively. This corresponds to the attainment of physical maturity at 24 GLGs in males and 16 GLGs in females. Asymptotic mass for males could not be determined, while for females it occurred around 160 kg. The maximum age estimates and recorded lengths were 24 GLGs and 279 cm for males and 17.7 GLGs and 249 cm for females. Differences in length-at-age and mass-at-age for S. chinensis suggest sexual dimorphism. The attainment of sexual maturity in males occurred between 9 and 10 GLGs, corresponding to 230 cm total body length and 140 kg. The maximum combined testis mass of mature males comprised 0.42% of total body mass, and a roving male mating system was proposed. In females, sexual maturity occurred around 7.6 GLG, between 220 and 222 cm and 104 - 140 kg. The ovulation rate is estimated at 0.2 ovulations per annum, suggesting a calving interval of five years. It is evident from the results obtained in the present study that geographical differences exist in the life history parameters of S. chinensis. As a result, regional conservation and management strategies are imperative. Results from this study can therefore assist in assessing the status of existing population structures in the KwaZulu-Natal coastal waters, and the implementation of regional mitigation strategies to ensure the continued survival of humpback dolphins in the region.

  • Description: Co-chaperones are important mediators of the outcome of chaperone assisted protein homeostasis, which is a dynamic balance between the integrated processes of protein folding, degradation and translocation. The Networking of Chaperones by Co-chaperones describes how the function of the major molecular chaperones is regulated by a cohort of diverse non-client proteins, known as co-chaperones. The second edition includes the current status of the field and descriptions of a number of novel co-chaperones that have been recently identified. This new edition has a strong focus on the role of co-chaperones in human disease and as putative drug targets. The book will be a resource for both newcomers and established researchers in the field of cell stress and chaperones, as well as those interested in cross-cutting disciplines such as cellular networks and systems biology.

  • Description: Pans on the African Erosion Surface near Grahamstown are small features, which, perhaps due to their small size have been neglected by researchers. From the outset the striking difference of these pans relative to other pans in southern Africa, is that the host rock is silcrete, a highly resistant rock well known as being associated with deeply weathered plateaus. The dominant origin theory for pans in southern Africa was developed by Goudie and Thomas (1985), and focuses on mechanisms relating to erosion and deflation. This model does not fit in well with the pans that have formed on substrate that has largely been unaffected by erosion in recent geological history (thousands to 10 000 years). As such this study examined the role of prolonged chemical weathering of Dwyka Tillite, that has led to the formation of silcrete. The hypothesis was that such deep weathering is responsible for local scale volume changes, which have in turn led to the formation of a depression. The centre of the pan indicated the highest concentration of Al₂O₃ and kaolinite at mid depths, and their concentrations decreased vertically away from these depths, and laterally towards the margins of the pan. Similar results were noted for SiO₂, while CaO and MgO (and calcite and dolomite) were highest at mid depths along the margins of the pan, and decreased laterally toward the centre of the pan. Results indicated that there was a positive relationship in the centre of the pan between: - the degree of chemical weathering and volume losses, - relative elevation of the pan and volume changes. Geochemically and mineralogically, there was a link between the high concentrations of Ca and Mg carbonates and volume gains in the margin of the pans. It is proposed that transpiration of vegetation along the margin of the pan caused the lateral movement of solutes, and the selective exclusion of these solutes by plants was associated with carbonate precipitation, leading to the creation of local relief. These results provide evidence to suggest that weathering and precipitation processes occurring over geological time scales are responsible for minor scale relief features, whose origin has been mistakenly attributed to deflation processes occurring over hundreds to thousands of years.

  • Description: The rural women in EMLM hew the wood, carry water, satisfy the men, produce and take care of the children to continue the family tree, and manage all the household chores. Their contribution is central to the effective functioning of families and communities. Yet, in terms of decision-making and local governance structures, they are absent. Indeed, there is truly a large constituency of women out there who are largely unrepresented; and therefore, they have no idea how governance is conducted – even around them. This is unfair, especially in jurisdictions where women are clearly in the majority. It is inconceivable that local governance structures have over a decade recorded only a single elected female member. With this in mind, this study seeks to explore the extent of rural women’s participation in local governance in Elias Motsoaledi Local Municipality. It is a comparison of traditional and democratic local governance structures; and the methods the researcher has used are qualitative and quantitative data on women councillors from 2013, in order to assess the factors that may be accountable for their small numbers, as compared to their male counterparts. The conclusion drawn was that the social structure, its traditions and cultural was identified in the study as the main obstacle to the advancement of women in the political arena. This study has not exhausted all the facets of the challenges; but it has brought a few to the fore, in an attempt to help stimulate debate, and inform policy and practice in the future.

  • Description: Country is a familiar topos in South African literature, featuring in travel writing and the farm novel, in imperial romance and postcolonial narratives, as pastoral and as anti-pastoral, an uncanny presence in the landscape of modernity. A surprising number of recent South African novels present what may be called post-apartheid country narratives. I am particularly interested in the return to country in J. M. Coetzee's Disgrace, Justin Cartwright's White Lightning, and Damon Galgut's The Impostor. Given the history of settler occupation of the land, and the literary deployment of the idea of the land both to posit and to problematize white settler identity, why these stories of a white man's return to the land in the post-apartheid period? What is the impulse behind retracing of contested ground?.

  • Description: Renewable energy has become an important feature of most modern economies with clean and non-exhaustible sources of power being given a greater significance. Wind energy is one of the favoured renewable, as it is (2013) generally the cheapest and most mature technology available for commercial use. The South African government, as outlined by the Department of Energy's Integrated Resource Plan (IRP), aims to install 5 GW (Gigawatts) of wind energy by 2020. However, South Africa has had little experience in the wind energy industry which is limited to two projects, Klipheuwel (2002) and Darling (2008). Much effort has been dedicated to calculating balance sheet costs, which carries uncertainty due to the high reliance on country specific and site specific variables. An aspect which deserves more attention, and is often ignored, is the public‟s attitudes towards local wind farm developments, which have been known to "make or break" a project during the planning stages. Public backlashes have mostly been concerned with the visual "intrusiveness" of wind farms in the landscape. Detrimental effects on scenery, while seemingly innocuous, are acknowledged as being the single largest barrier to successful wind farm development. Individuals within an area become sentimentally attached to their surroundings, where significant rapid changes in the landscape are viewed as "damage". Economics recognises such declines in scenic resources as market failures, where an externalised cost is passed on to the public and is often not accounted for by private parties responsible for the liability. The primary objective therefore was to measure the magnitude of the visual impact, caused by the Waainek Wind Farm, on the Grahamstown community. Conventional NIMBY¹ (not in my back yard) reasoning, which seeks to explain local wind farm resistance, has attracted criticism with regard to its simplistic approach to wind farm problem identification. Contemporary arguments propose that NIMBY is a poor explanation for the trouble experienced on the local level because it groups problems into one all-encompassing term, leaving much of the discontent unexplained. Instead, the NIMBY explanation is really a broad set of unattended problems, largely resulting from the unsound practices present in the public participation process. Insufficient community involvement and disparities in the negotiation power structures have become the recent focus in wind farm literature. Essentially, these disparities force opposition groups to select factors which may seem more serious to developers, leading to ineffective remedial measures because the core underlying problems are not being remedied. Thus these considerations formed an additional area of investigation. No NIMBY effect was found for the Grahamstown community, as support for both the local and general level was roughly 80%. The public participation process on the other hand revealed that while many found the practices of the developer to be unfair, attitudes towards the wind farm were not adversely affected, especially for the lower income Grahamstown East areas. While the public participation process in this instance did not have any effect on people’s attitudes, careful inspection of the circumstances need to be given. Wind farms are new to South Africa, where the novelty and benefits are the focus of enthusiasm. Job opportunities as well as clean energy are positive drivers for attitudes; however given time, once the anticipation for wind farms dulls, real problems may be revealed. Thus it is crucial to implement good practice procedures during the public participation process, especially when national adoption rates of wind energy are low. Early implementation of an effective public participation process system will ensure that when major problems do arise in future projects, experience and institutional processes would have had ample opportunity to evolve appropriately over a period of time. The double bounded Contingent Valuation Method was used to value the impact of the wind farm on the Waainek scenery through a hypothetical scenario based procedure which presented pictures of the landscape before and after the wind farm had been installed. Based on the perceived impact of the wind farm, respondents were asked their Willingness to Pay to relocate the development, based solely on visual impacts. Learning design Contingent Valuation (Bateman et al., 2008) is a novel technique employed to familiarize respondents with the hypothetical market institution as well as the scenic goods being valued. Average Willingness to Pay was found to be R67 per month, with a final total monthly negative visual impact of R104,000 to R121,000 per month for the entire Grahamstown community. Grahamstown Central (middle-high income) residents were more likely to pay than Grahamstown East (low-middle income) East residents because of socio-economic differences present in each area. A ranking exercise determined that while negative visual impacts are present, the overall benefits derived from the wind farm are potentially much higher. Additionally, positive scenic improvements were found, but were not measured due to time constraints, and would have worked to reduce the net visual impact of the Waainek Wind Farm. ¹Problem where individuals support the general concept of wind power, but when it comes to local implementation, opposition to the development arises within the same group.
