- Description: There has been significant debate about the land occupations which occurred from the year 2000 in Zimbabwe, with a key controversy concerning the role of the state and ruling party (or party-state) in the occupations. This controversy, deriving from two grand narratives about the occupations, remains unresolved. A burgeoning literature exists on the Zimbabwean state’s fast-track land reform programme, which arose in the context of the occupations, but this literature is concerned mainly with post-occupation developments on fast-track farms. This article seeks to contribute to resolving the controversy surrounding the party-state and the land occupations by examining the occupations in the Shamva District of Mashonaland Central Province. The fieldwork for our Shamva study focused exclusively on the land occupations (and not on the fast-track farms) and was undertaken in May 2015. We conclude from our Shamva study that involvement by the party-state did not take on an institutionalised form but was of a personalised character entailing interventions by specific party and state actors.

- Description: Care and safety of learners refers to the behavioral practices which protect children from danger, risks and injuries. It also includes environment that is free from violence since where there is no fear perceived, there is reverence for the school and its disciplinary measures (Hernandez & Seem, 2004; Marotz, Cross, Rush, 2005; Mathe, 2008; Chukwu, 2008). Schools should have positive environment which allows members of staff, learners and guests to freely interact without threats or fear. Learners and staff should feel psychologically, physically and emotionally safe and secure (Dwyer & Osher, 2000; Tabancali &Bektas, 2009; Butcher& Manning 2005). Consequently, care and safety of learners can also be viewed in a more practical and management oriented way. According to Hull (2010) care and safety of learners in a management oriented way includes, maintenance of school buildings and grounds, care of facilities, furniture and equipment with spacious corridors that allow free flow and emergency movement to prevent illness and death. Classes should accommodate the required educator-learner ratio. The playgrounds are reduced to limited space to ensure that learners are visible and are controllable. Moreover provision of care and safety of learners includes school culture and the appropriate training of educators as well as school staff who should respond to threats and hazards. It also includes addressing the range of crisis the school can face such as death and natural disasters (Phaneuf, 2009). Reeves, Nickerson, Conolly-Wilson, Suson, Lazzaro, Jimerson, and Pesce (2012) contend that the educators on duty should provide learners with safety precautions to guard against the possibility of single learner slipping away and suffering injuries (Dilion, 2007). According to Mogopodi, Banyaladzi & Petros (2015) facilities like laboratories should be suitable for all learners because they help to transform theoretical education into practice making learning effective. Astor, Guerra, Van Acker (2010) suggest that provision of care and safety for learners is among the most essential components for achieving effective teaching and learning. This will only be achieved by putting in place proper care and safety programmes and ensuring that they are effectively implemented (Netshitahame, & Vollenhoven, 2002, Astor et.al.2010).

- Description: Temporary lentic wetlands are becoming increasingly recognised for their collective role in contributing to biodiversity at the landscape scale. In southern Africa, a region with a high density of such wetlands, information characterising the fauna of these systems is disparate and often obscurely published. Here we provide a collation and synthesis of published research on the aquatic invertebrate fauna inhabiting temporary lentic wetlands of the region. We expose the poor taxonomic knowledge of most groups, which makes it difficult to comment on patterns of richness and endemism.

- Description: Despite agricultural land abandonment threatening the food security and the livelihoods of smallholder farmers, it is pervasive globally and in developing countries. Yet land abandonment is an understudied aspect of land use change in social–ecological systems. Here we provide more information on this phenomenon by exploring cropland abandonment during 1950–2010 in four former South African ‘homelands’—part of the ‘Apartheid’ era racially-based land allocation programs—characterized by rural, smallholder farmers. Cropland abandonment 1950–2010 was widespread in all surveyed sites (KwaZulu: 0.08% year−1, Transkei: 0.13% year−1, Lebowa: 0.23% year−1, Venda: 0.28% year−1), with rates peaking between 1970 and 1990, with concomitant increases (up to 0.16% year−1) of woody vegetation cover at the expense of grassland cover. Active and past farmers attributed cropland abandonment to a lack of draught power, rainfall variability and droughts, and a more modernized youth disinclined to living a marginal agrarian lifestyle. We discuss the potential social and ecological implications of abandoned croplands at the local and regional scales, as the deagrarianization trend is unlikely to abate considering the failure of current South African national agricultural incentives.

- Description: Hospital-acquired infections (HAIs), caused by viral, bacterial and fungal pathogens, can have a devastating effect on patients, families and health-care organisations. Furthermore, dealing with HAIs can be costly and add to an increase in hospital stays, medical costs, as well as the rates of morbidity and mortality. Operating rooms (OR) are dynamic units that pose a high risk for surgical infections in health-care organisations. In order to minimise surgical-site infections (SSI) and other related infections in ORs, it is important to care for and handle surgical instruments correctly and in accordance with what is considered to be best practice. This research study was conducted to explore and describe the knowledge of professional nurses related to the care and handling of surgical instruments in the ORs in the medical facilities both in the private and public sectors in Nelson Mandela Bay (NMB). The research design was quantitative, explorative, descriptive and contextual in nature. The research sample comprised of professional nurses in the ORs in the public and private hospitals, who made themselves available and who were willing to participate in the study. The data was collected by means of a structured self-administered questionnaire that was based on a narrative literature review. Descriptive statistics were used to analyse the responses from the professional nurses in the OR, collected using the questionnaire. Ethical considerations have been applied throughout the research study and all the relevant findings have been disseminated accordingly. Recommendations, based on best-practice guidelines, were developed to optimise the care and handling of surgical instruments by professional nurses in the ORs. Professional nurses in the ORs who are involved in cleaning surgical instruments should know how to manage certain cleaning procedures. Disinfection and the sterilisation of surgical instruments can only be achieved by following efficient cleaning procedures. When performed properly, cleaning can effectively reduce the growth of microorganisms on surgical instruments, in order to prepare the instruments for disinfection and sterilisation. The importance of this step cannot be overemphasised since organic material, soil and debris can block the disinfectant or sterilising agent from making complete contact with the surface of the instruments. Additionally, cleaning allows for the safe handling of the instruments by professional nurses.

- Description: The main objective of this MSc study was to disentangle whether temperature or the presence of non-native fish was limiting the distribution of Pseudobarbus afer (Peters, 1864) in the Blindekloof stream, Eastern Cape, South Africa. The aims were to: i) describe the thermal regime of the Blindekloof stream; ii) conduct experiments to determine the preferred and critical temperatures of P. afer and; iii) use snorkel surveys to contextualise the distribution of both native and non-native fishes in the Blindekloof stream to assess whether the downstream distribution of P. afer was likely to be influenced by temperature or by the presence of non-native, predatory fishes. To describe the thermal regime, year-long temperature data from four long term monitoring sites in the Blindekloof stream were collected using Hobo temperature loggers and analysed in order to better understand the thermal profile, the thermal variation and the rate of temperature change in the stream. The warmest temperatures were recorded in late December 2015 (absolute maximum of 29.4 °C). The coolest water temperatures were recorded in early August 2015 (absolute minimum of 9.5 °C). There is both seasonal and diel variation in temperature with mean, minimum, maximum, 7 day mean, 7 day maximum and temperature ranges differing significantly between sites. With knowledge of the thermal regime of a monitored reach of the Blindekloof stream, the thermal tolerance and preference of P. afer were investigated. The thermal tolerance of P. afer was investigated using the Critical Thermal Method (CTM) which uses non-lethal endpoints (the loss of equilibrium). At low acclimatization temperatures (11.9 ± 0.7 °C), the mean CTmax of P. afer was found to be 29.9 ± 0.7 °C, while at a higher acclimatization temperature (19.9 ± 0.1 °C), the mean CTmax was 35.1 ± 0.6°C. Custom-built thermal choice tanks were used to investigate the thermal preference of P. afer in both summer and winter. The preferred median temperatures for the summer experiments ranged from 22.4 - 29.3 °C while the winter preferred median temperatures ranged from 18.5 - 23.1 °C. The thermal tolerance of P. afer was compared to the thermal regime of the stream and the results suggest that temperature is not limiting the distribution of P. afer. Snorkel surveys were used to determine the distribution of fishes in the Blindekloof stream. Analysis of the distribution data suggests that, in the absence of non-native predatory species, native fishes have the potential to inhabit pools throughout the system right to the confluence, thus predatory fishes and not temperature was limiting P. afer distributions.

- Description: As South Africa moves into an era of National Health Insurance (NHI), the idea of primary health care (PHC) re-engineering is placed at the forefront; however, the role of the pharmacist in this process remains vague. Task-shifting of the dispensing process to pharmacist’s assistants and nurses in PHC clinics is a common phenomenon, but the implications of this on the provision of pharmaceutical services and care to patients is largely unstudied. Thus, this study aims to explore these pharmacist-based, pharmacist’s assistant-based and nurse-based dispensing models present in PHC clinics. A two-phase, mixed methods approach was utilised, comprising of a pharmaceutical services audit and semi-structured interviews. The interviews provided insight into the lived experiences of personnel and patients of pharmaceutical care provision. Results revealed that although basic pharmaceutical services may be available at clinics with each of the three dispensing models, the quality is of a varying standard due to challenges in infrastructure and maintenance and poor personnel support.

- Description: As South Africa moves into an era of National Health Insurance (NHI), the idea of primary health care (PHC) re-engineering is placed at the forefront; however, the role of the pharmacist in this process remains vague. Task-shifting of the dispensing process to pharmacist’s assistants and nurses in PHC clinics is a common phenomenon, but the implications of this on the provision of pharmaceutical services and care to patients is largely unstudied. Thus, this study aims to explore these pharmacist-based, pharmacist’s assistant-based and nurse-based dispensing models present in PHC clinics. A two-phase, mixed methods approach was utilised, comprising of a pharmaceutical services audit and semi-structured interviews. The interviews provided insight into the lived experiences of personnel and patients of pharmaceutical care provision. Results revealed that although basic pharmaceutical services may be available at clinics with each of the three dispensing models, the quality is of a varying standard due to challenges in infrastructure and maintenance and poor personnel support. Furthermore, the provision of quality pharmaceutical care is minimal with all three dispensing models, resulting in a missed opportunity to optimise patient health outcomes in patient-centred PHC.

- Description: Fibronectin (FN) plays a major role in the stability and organization of the extracellular matrix (ECM). We have previously demonstrated that FN interacts directly with Hsp90, as well as showing that the Hsp90 inhibitor novobiocin results in FN turnover via a receptor mediated process. However, the receptor involved has not been previously identified. LRP1 is a ubiquitous receptor responsible for the internalisation of numerous ligands that binds both Hsp90 and FN, and therefore we investigated whether LRP1 was involved in novobiocin-mediated FN turnover.

- Description: The extracellular matrix (ECM) serves as a scaffold for cells within tissues and is composed of an intricate network of glycoproteins, growth factors and matricellular proteins which cooperatively function in cell processes such as migration, adhesion and wound healing. ECM morphology is constantly undergoing remodelling (synthesis, assembly and degradation) during normal cell processes and when deregulated may contribute to disease. Heat shock proteins (Hsps) are involved in regulating processes that determine the assembly and degradation of the ECM at multiple levels, in both normal and diseased states. These roles include mediating the activation of ECM-degrading enzymes, maintaining matrix stability and clearing aggregated/misfolded proteins. Hsp may serve as chaperones and receptors or have cytokine-like functions. In this chapter, we review how Hsp90, Hsp70, Hsp40 and a number of ER resident chaperones contribute to ECM regulation. The role of the non-Hsp chaperones, SPARC and clusterin in the ECM is also discussed.

- Description: The adoption of a critical spatial perspective is imperative, if social justice is to be performed in urban environments, according the urban theorist Edward Soja. From this perspective of a socio-spatial dialectic, understood using Lefebvre’s ideas around the social production of space and the right to the city, the current spatial conditions of Port Elizabeth are seen as perpetuating past constructions of inequity. In these constructions of inequity large, systematically oppressed groups of the public are forced to traverse across segregating urban barriers to access the opportunity and advantages of living in an urban system. This condition continues to disadvantage those it was historically set up to undermine, on economic and social terms. This condition subverts these urban nomads, who are those forced into transience to access urban opportunity. Korsten is investigated as a key transition space in the Port Elizabeth area, straddling the impoverished north and wealthy south, as one of the key spaces where the urban nomad moves through to access better resourced parts of the city. The space of Korsten is understood to be a key domain for the urban nomad in Port Elizabeth and is thereby an appropriate place for intervention to intensify the city and improve urban quality, thus dignifying and enriching the lives of citizens and improving equity in the city. The notion of opportunity is focused on as the catalytic vehicle for urban quality to be improved, ultimately resulting in the design of Korsten as an urban resources centre with new educational and economic resources as a central structuring element in a re-scripted field of resources. The architectural design is produced within the paradigm of field conditions. This results in a design product which integrates as a part of a field condition of public resources in Korsten. A qualitative methodology is adopted within the critical research paradigm and will use methods of desktop surveys, literature reviews and participant observation to collect data.

- Description: The South African Reserve Bank (SARB) implemented inflation targeting as a monetary policy framework in 2000 with the aim of achieving low and stable price associated with economic growth. However, the period in which the framework was implemented is characterised by periods of price instability and low economic growth. This contradicts the view of different views in the literature that indicates that inflation targeting ensures low inflation rates. The purpose of the current study was to investigate the nexus between monetary policy credibility, exchange rate pass-through and inflation in South Africa. The study employed the Johansen co-integration test, Vector error correction modelling (VECM) techniques, impulse response and variance decomposition for the period from 2000 to 2017 using quarterly data. The Johansen cointegration indicated that there was a long-term relationship between the variables of interest. The VECM was estimated together with the impulse response and variance decomposition. The empirical results indicated that the variables utilised in the study are positively related. Impulse response functions also proved that in the long run, changes in consumer prices are a result of fluctuations in oil prices and the repo rate. It is evident that consumer prices (inflation) are positively related to changes in exchange rates and monetary policy credibility. Thus, the study recommends that changes in the exchange rate must be considered when implementing the monetary policy as the prices move in the same direction as changes in the NEER. Further, the lack of monetary policy credibility seems to be an issue for monetary authorities as there is supposed to be an inverse relationship among the CPI and MPCRED, which is opposed by the study. Additionally, the results also indicate that the repo rate is positively related to the consumer price and this opposes previous literature. Thus, recommending that the SARB needs to evaluate the monetary policy or the inflation targeting framework to ensure they achieve credibility

- Description: The majority of the people in South Africa were poor prior 1994, especially those in the rural areas. Poverty in the rural areas affected mostly the women. The government of South Africa designed support programmes to mainstream women into the economy, although it had its own challenges, such as the non-participation of women in their own development and the top-down approach that at times was used by the government in the implementation of the programmes. Owing to the nature of the rural areas, agriculture was identified as a sector that had a potential to improve the economy in order to address the challenges of unemployment, poverty and inequality. Since 2005 the concept of cooperative development has been a vehicle that has the potential to address the aforementioned challenges. In order for the cooperative development to run efficiently and effectively and in line with the cooperative principles and values, the government should keep the independence of this sector in mind by engaging the cooperatives in all the activities that were affecting the cooperative sector through their cooperative movement.The findings of the study showed that the agricultural cooperatives have not yet addressed poverty fully. All their members were employed and at times employment opportunities were extended to their community members, but the income earned was not satisfying its members. The women felt that they were not in control of their development as they lacked the capacity to lead and they were still led by the men in their cooperatives.

The Moravian Church music heritage is documented through the lens of Coloured composers of Moravian church music. In my study, I highlight the origins of the Moravian Church and its underlying philosophies by focusing on important figures and treasures of the Moravian Church. I provide a brief outline of the Moravians’ contribution to education and music. In the study I discuss the importance of record-keeping and rich hymnody of the Moravian church. I also discuss the doctrine, worship and sacraments of the Moravian Church. The literature study provides the history of the music of the American Moravian Church. This serves as a basis for comparison with the Moravian Church music tradition in South Africa, which is discussed in chapter four of this study. Furthermore, I provide an account of the history of the Moravian Church in South Africa. I use the qualitative research method of case studies to detail the music departments of a selected number of congregations within the Moravian Church of South Africa. Chapter five contains biographies of South African Moravian composers. This research adds to the body of new knowledge through the provision of a comprehensive list of South African Moravian composers and provides the first annotated bibliography of their works. Finally, my study concludes with the provision of a theoretical framework for the establishment of a Moravian Music Foundation based on the North American Moravian Music Foundation model.

- Description: Mangrove habitats are considered as the ideal fish nursery as they are known to increase the growth and survival of juvenile fishes by providing enhanced food availability and protection. However, most studies have focused on tropical mangroves with a few recent warm temperate studies finding conflicting results. Furthermore, the nursery value of South African mangroves to fishes remain understudied in subtropical areas, while warm temperate mangroves are yet to be evaluated. This study aimed to assess whether mangrove presence leads to any advantage to the larvae of an important estuarine resident fish species, Gilchristella aestuaria, by comparing the food patch quality of South African warm temperate mangrove and non-mangrove estuaries. Results indicate that larvae fed primarily on the dominant prey species, Pseudodiaptomus hessei, Paracrtia longipatella, and Acartiella natalensis. However, postflexion larvae consumed more of the larger species, P. hessei, within the two mangrove estuaries (16.09 %V in Nahoon and 13.79 %V in Xhora) than the two nonmangrove estuaries (12.20 %V in Gonubie and 7.05 %V in Qora), despite other prey species occurring at similar densities. Results indicate that mangrove habitats acted as sediment sinks, slightly reducing the turbidity of these estuaries which resulted in postflexion larvae actively selecting larger, more nutritious prey, which in turn, significantly increased their individual instantaneous growth rates (0.11 ± 0.21 Gi) when compared to postflexion larvae in non-mangrove estuaries (0.09 ± 0.12 Gi). This study found that mangrove presence was significantly related to postflexion larval densities when coupled with abiotic (such as temperature and turbidity) and biotic factors (such as predator-prey interactions). Understanding the spatial and temporal dynamics, predator-prey interactions as well as the growth and survival of G. aestuaria is particularly important as they are key zooplanktivores that are prey to other species in estuarine food webs.

- Description: Engineering is of vital importance for humankind. Engineering combines the fields of mathematics and science, including engineering science and technology, in order to solve problems in the real world and in order to improve the society and economies of countries. It includes the ability to implement ideas in a cost effective and practical manner. Some of these solutions may include sustainability, needs of society, necessary risks and protection of the environment. Engineers develop ideas by using production of technology in order to improve the living of humankind. This includes designing and manufacturing different products based on customer needs and expectations. Although a field in engineering is largely a male-dominated career, women are becoming more interested in this career, compared to a few years ago. The problem remains that female students are still in the minority compared to their male counterparts studying engineering. Therefore, universities need to find solutions to attract female students towards engineering. There are various reasons why female students choose to study engineering, which include different influences, encouragements and their perception towards the Faculty and the academic staff. Thus, the purpose of the research study is to identify the reasons for both genders, currently studying engineering at Nelson Mandela University, formally known as Nelson Mandela Metropolitan University (NMMU), why they chose to study engineering, what influenced their studies, their encouragements or discouragements and overall perception and experience while studying engineering. The main focus will be on female students. This research study was an exploratory, mixed method study, which contains literature studies, surveys and cross-sectional studies. A literature study was compiled by using secondary sources in order to identify the importance of engineering internationally and within South Africa, women in the workplace and female students studying towards engineering. The empirical study, which consisted of a survey, was compiled and distributed to all Nelson Mandela University undergraduate students studying towards an engineering qualification. Respondents were asked various questions regarding pre-studies and their perceptions and experiences during their studies. This includes their experience with the academic staff and the Faculty of Engineering in general. For the analysis of the data, both Descriptive and Inferential Statistical methods were used. Some of the findings from the research study include that both genders develop an interest for engineering at a young age (between ages 13 – 18). Therefore, an interest is developed during high school level. Both genders choose to study engineering for the same reasons. The interest for choosing a career for both genders was triggered by a qualified engineer’s influence. During high school, female students take part in science, mathematics and engineering programmes and participate in competitions or contests. Both gender’s science, mathematics and engineering abilities increased since they started their studies at a higher education institution. From the findings, both genders indicated that they have a high level of interest in engineering, they are satisfied with their choice of engineering field and they are committed to complete their engineering qualification. Both genders are confident that they will find employment in engineering that pays well. Female students believe that they are better at problem solving activities, they are more committed to their studies, they work better with other people and they are more confident in their engineering abilities compared to the male counterparts. The findings also include that during their studies, both genders receive encouragement from various factors, but the significant source of encouragement for both genders are their mothers and employment opportunities. Whereas the most significant source of discouragement for both genders are their grades or academic performance and the amount of time required for engineering. Both genders receive equal quality in lecturing throughout their studies and the academic staff do not treat female students different from male students. It is also significant that female students receive support from the Faculty of Engineering. Female students will definitely encourage other females to study towards a field in engineering and find the academic staff approachable. Academic staff does give regular feedback to students regarding their academic performance. Therefore both genders know at all-time their academic performance and therefore will be able to improve their results. There are not enough female lecturers within the Engineering Department. Female lecturers serve as role models for female students. Therefore, the University’s management team needs to investigate this matter. The research study concluded with recommendations and considerations, contribution towards the body of knowledge, future research and the limitations of the study. Furthermore, the study offers an understanding of engineering students at Nelson Mandela University, which includes their current overall experience during their studies. The treatise will therefore assist the readers and especially Nelson Mandela University to attract and retain female students by addressing their challenges they experience during their studies.

- Description: Engineering is of vital importance for humankind. Engineering combines the fields of mathematics and science, including engineering science and technology, in order to solve problems in the real world and in order to improve the society and economies of countries. It includes the ability to implement ideas in a cost effective and practical manner. Some of these solutions may include sustainability, needs of society, necessary risks and protection of the environment. Engineers develop ideas by using production of technology in order to improve the living of humankind. This includes designing and manufacturing different products based on customer needs and expectations. Although a field in engineering is largely a male-dominated career, women are becoming more interested in this career, compared to a few years ago. The problem remains that female students are still in the minority compared to their male counterparts studying engineering. Therefore, universities need to find solutions to attract female students towards engineering. There are various reasons why female students choose to study engineering, which include different influences, encouragements and their perception towards the Faculty and the academic staff. Thus, the purpose of the research study is to identify the reasons for both genders, currently studying engineering at Nelson Mandela University, formally known as Nelson Mandela Metropolitan University (NMMU), why they chose to study engineering, what influenced their studies, their encouragements or discouragements and overall perception and experience while studying engineering. The main focus will be on female students. This research study was an exploratory, mixed method study, which contains literature studies, surveys and cross-sectional studies. A literature study was compiled by using secondary sources in order to identify the importance of engineering internationally and within South Africa, women in the workplace and female students studying towards engineering. The empirical study, which consisted of a survey, was compiled and distributed to all Nelson Mandela University undergraduate students studying towards an engineering qualification. Respondents were asked various questions regarding pre-studies and their perceptions and experiences during their studies. This includes their experience with the academic staff and the Faculty of Engineering in general. For the analysis of the data, both Descriptive and Inferential Statistical methods were used. Some of the findings from the research study include that both genders develop an interest for engineering at a young age (between ages 13 – 18). Therefore, an interest is developed during high school level. Both genders choose to study engineering for the same reasons. The interest for choosing a career for both genders was triggered by a qualified engineer’s influence. During high school, female students take part in science, mathematics and engineering programmes and participate in competitions or contests. Both gender’s science, mathematics and engineering abilities increased since they started their studies at a higher education institution. From the findings, both genders indicated that they have a high level of interest in engineering, they are satisfied with their choice of engineering field and they are committed to complete their engineering qualification. Both genders are confident that they will find employment in engineering that pays well. Female students believe that they are better at problem solving activities, they are more committed to their studies, they work better with other people and they are more confident in their engineering abilities compared to the male counterparts. The findings also include that during their studies, both genders receive encouragement from various factors, but the significant source of encouragement for both genders are their mothers and employment opportunities. Whereas the most significant source of discouragement for both genders are their grades or academic performance and the amount of time required for engineering. Both genders receive equal quality in lecturing throughout their studies and the academic staff do not treat female students different from male students. It is also significant that female students receive support from the Faculty of Engineering. Female students will definitely encourage other females to study towards a field in engineering and find the academic staff approachable. Academic staff does give regular feedback to students regarding their academic performance. Therefore both genders know at all-time their academic performance and therefore will be able to improve their results. There are not enough female lecturers within the Engineering Department. Female lecturers serve as role models for female students. Therefore, the University’s management team needs to investigate this matter. The research study concluded with recommendations and considerations, contribution towards the body of knowledge, future research and the limitations of the study. Furthermore, the study offers an understanding of engineering students at Nelson Mandela University, which includes their current overall experience during their studies. The treatise will therefore assist the readers and especially Nelson Mandela University to attract and retain female students by addressing their challenges they experience during their studies.

- Description: Bollywood’s popularity as a global cultural form has occurred at the same time as the valorization of difference in the South African political landscape. As the youngest members of the 19th-century labour diaspora, South African Indian youths are the inheritors of a conservative—yet adaptable—home culture amidst the marginalized identities of (post-)apartheid South Africa. Their desire to create an identity for themselves that encompasses their self-perception both as modern South African subjects and as guardians of their traditional home cultures is achieved through Bollywood, which speaks to its diasporic audiences through images of an idealized traditional yet modern India. While India is not a place of return for these youth, their reactivation of a diasporic identity through Bollywood’s representations of a successful Indian diasporic culture and their participation in South African Bollywood concerts and award ceremonies has provided an opportunity for young South African Indians to reimagine their diasporic Indian identity in ways that (re-)connect them to India and to an imagined global diaspora.
