- Description: Small and Medium Enterprises (SMEs) are engines of growth. It has been determined globally that these enterprises are the largest employers in economies. Small and Medium Enterprises fail fundamentally to succeed in South Africa. Many challenges and barriers were identified as the reason why the enterprise fails to survive or succeed for at least 42 months. Poor performance of the SMEs could be blamed on the lack of meaningful support including an over-regulated environment, red tape and the poor quality of education and training. A number of Small and Medium Enterprise owners in Turkey were interviewed to determine if the enterprise development support system contributed to success and economic growth. The government succeeded to improve the economy of Turkey profoundly by investing and supporting this very important sector. Turkey is positioned 17th in the world based on the Gross Domestic Product (GDP). The purpose of this study was to develop an entrepreneurial development framework for SMEs in South Africa. The government needs to support and implement this framework to stimulate economic growth, to address the poor quality of education and training and to establish a system to measure the performance of critical success factors. A case study research approach was employed to address five propositions that were investigated in this research project. Semi-structured interviews studied the perceptions and experiences of the SME owners in Turkey. The study found a positive relationship between economic growth, a meaningful enterprise development support system, education and training, critical success factors and entrepreneurship and the perceived success of entrepreneurial ventures in South Africa. The establishment and implementation of an entrepreneurial development framework will encourage the creation of new ventures. The government will be able to achieve the goal of economic growth as set out in the National Development Plan. The establishment of SMEs will result in employment, social stability, economic growth and the generation of tax revenues. The purpose of an entrepreneurial development framework is to ensure the sustainable economic development and prosperity of South Africa.

- Description: Savanna degradation is an environmental problem occurring in most countries around the world and it poses threats to biodiversity conservation, the food industry, and other economic sectors. According to FAO, South Africa’s rangelands exhibit the highest rate of fragmentation in comparison to range ecosystems in neighbouring countries including Lesotho and Swaziland, and consensus among researchers is that communal rangelands are more degraded than commercial rangelands. Although researchers and communities have identified the occurrence of land degradation in communal savannas at a local scale, land degradation has been poorly estimated because little has been done to quantify the extent and dynamics of perceived and observed changes associated with land degradation. The main goal of this study is to provide empirical insights on the direction of changes in the communal savannas of Nkonkobe Local Municipality in order to inform policy formulation and implementation. Additional to the communal sites is a private farm included for comparative analysis of trends in communal and commercial savannas. Landsat imagery was used to map, assess, and quantify the extent of land degradation in Nkonkobe Local Municipality, over a period of 30 years between 1984 and 2014. Field investigations were undertaken in June 2015 to acquire reference data to guide supervised classification of Landsat images. Three algorithms (Mahalanobis-distance, Minimum-distance, and Maximum likelihood classification) were compared to identify a classifier that produced the best results. The maximum likelihood classifier produced the best results with classification accuracy levels of 95.24 percent, 89.66 percent, and 95.65 percent for Honeydale Farm, Thyume, and Sheshegu respectively. Regression analysis revealed that both communal and private lands have experienced statistically significant increases in bush encroachment and decreases in surface water. Communal savannas have been confronted more by expansion of built-up area, decrease in open grassland, abandonment of arable land, soil erosion, and a steady invasion by Acacia Karroo compared to the privately owned commercial farm. The land cover changes measured through this investigation suggest an environmental shift that threatens biodiversity and agricultural activity. The study provides empirically informed insights about the direction to which these savannas are changing with the hope that the findings will prompt formulation and implementation of effective policies.

- Description: This study was conducted in one of the education districts in the Eastern Cape Province of South Africa. The purpose was to analyse the effectiveness of the concrete/semi-concrete/abstract (CSA) approach and drill-practice instructional strategies on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. The following two objectives were set. First, to identify the learners’ challenges in studying addition and subtraction of algebraic fractions in grade 10; and second to analyse the effectiveness of the CSA approach and drill-practice instructional strategies on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. Both threshold concepts and troublesome knowledge, Polya’s problem-solving techniques, CSA Approach theory and Drill-practice theory were all pertinent as a theoretical framework for the study. Positivism research paradigm was adopted for the study and it afforded the researcher opportunity to employ quantitative research approach. Based on the research question of this study, an experimental design was chosen as a suitable descriptive design. Purposive sampling method was used to select three schools which involved 135 grade 10 mathematics learners. Stratified random sampling method was thereafter employed to select 45 learners from each school for the study. The learners were grouped in each school as top, average and weak based on their performance in Algebra in term one. Pre-questionnaire and post-questionnaire were used to obtain data regarding challenges learners experience in simplifying addition and subtraction of algebraic fractions. Ethical clearance from the relevant school and university authorities were obtained. On the first two days, the researcher briefed the school authorities and learners and explained to them the purpose and details of the study. Day three was used to administer the pre-questionnaire test, thereafter, the next ten days were used to teach addition and subtraction of both numeric and algebraic fractions with same and different numerators and denominators. The next two days were used for revision and the last day was used to administer the postquestionnaire test out 25 marks. The respondent rate was 98.5%. The data collected were analysed by using SPSS version 16.10. Both descriptive and inferential statistics were used to analyse the data. The pre-questionnaire scores revealed that majority of the learners’ perceived fractions as two separate entities and as a result add or subtract numerator to numerator and denominator to denominator. It was also discovered that learners had a challenge in finding LCM of algebraic fractions. A t-Test for independent means was used to test the following hypotheses at 𝛼 = 0.05: 𝐇𝟎: The CSA approach and drill-practice intervention has no significant effect on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions; 𝐇𝟏: The CSA approach and drill-practice will significantly enhance Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. The t-Test revealed a p-value of 0.139 which was statistically significant at 𝛼 = 0.05. Therefore, the researcher rejected the null hypothesis and concluded that the CSA approach and drill-practice have significantly enhanced the Grade 10 learners’ ability to simplify algebraic fractions.

- Description: This study critically examined the implementation of gender equality policies to enhance female leadership in Zimbabwean universities. Three theoretical frameworks were adopted for this study which were: The feminist critical policy analysis, top-down and bottom-up policy implementation theories. Within this study an interpretive paradigm which aligned with the qualitative approach and the case study design to better understand the phenomena were adopted. The study covered two state universities in Zimbabwe which were purposively selected. The participants who comprised Pro Vice Chancellors, Deputy Registrars Human Resources, Faculty Deans, Director of Gender Schools, Senior Administrative Registrars, Chairpersons of Departments and males and female academics were also purposively selected. Semi structured interviews, focus group discussion and document analysis were used as data collection instruments. Data were analysed using content analysis and the emerging results were organised into different themes reflective of the participant’s responses. The findings of the study presuppose that the state universities Zimbabwe were implementing gender sensitive organisational culture through open door policy and this promoted transformational leadership in both universities. The study revealed that both universities consulted internal and external gender experts and top-down and bottom-up consultations were made during policy formulation. It was discovered from the study that both universities had also utilised gender mainstreaming and affirmative action as strategies for promoting female leadership and gender equality. Despite teaching and learning, community engagement, research, recruitment and promotions which were used to promote the gender agenda, there were indications that these were being implemented in a haphazard manner. This adversely influenced active participation of females in decision making processes. The collected data also showed that both universities had enacted gender structures which were in line with international, regional and national gender policies and conventions and were being used to irradiate the importance of having gender parity in top positions. The findings of the study further illuminated that monitoring and evaluation of the gender equality policy and programs in place to advance females to leadership positions had not been done, leading to major impediments to achievement of gender balance. There also emerged a number of challenges which were uniform in both universities namely; lack of gender knowledge; commitment, lack of gender training and workshops, lack of consultation using bottom-up approach, gender budgeting and inadequate resources. Though the above mentioned were identified as encumbering features in both universities there was a substantiation of pockets of good practices. These were; implementation of gender equality policy, involvement of internal and external gender experts to policy formulation; promotion of shared power and authentic leadership through transparent selection of chairperson of departments; gender workshop and training; staff development programmes; enactment of gender structures, enhanced community engagement and liaison with NGOs to promote gender agenda at all levels. Regardless of the number of hurdles that indicate that universities continue to be fraught with challenges in promoting female leadership, the pockets of good practices are evidence that both universities are making positive strides through the implementation of gender equality policies to enhance female leadership. Therefore, to benchmark changes in universities, the study recommends that transformational leadership must permeate in all university structures to promote an organisational culture that is gender sensitive. There must be adequate resources, gender training and workshops; focal persons and points; commitment and political will, gender experts from governmental to ministerial levels and satellite gender structures. Monitoring and evaluation should be carried out in both universities and this should be guided by a framework so as to assist universities to tap into female empowerment and gender equality that will promote the interests of both genders, while retaining the quality and excellence in universities. Lastly, the findings of the study and the extant literature are indicative that enhancement of female leadership in universities is currently affected by a number of challenges. Therefore, as part of redress, the researcher recommends a comprehensive framework which illuminates pockets of good practices in implementing gender equality policies to enhance female leadership in universities.

- Description: Flocculation has been widely adopted as one of the most effective methods to remove colloidal particles in water or wastewater treatment. Synthetic flocculants are conventionally used because of their high flocculating efficiency and cost-effectiveness. However, they have been reported to have hazardous properties and implicated in some serious health problems including senile dementia and neuro-toxicity, as well as being recalcitrant in the environment. Consequently, efforts are being geared away from the use of synthetic flocculants in water and wastewater treatment. Hence, the need for safe and eco-friendly flocculants has become imperative. Compared with synthetic flocculants, bioflocculants have special advantages such as safety, biodegradability and harmlessness to the environment and humans; attributes which make them potential alternatives in water treatment, downstream as well as fermentation processes. In the current study, the potentials of bacterial isolates recovered from Algoa Bay in the Eastern Cape Province of South Africa for bioflocculant production were investigated. The bacterial isolates were identified by polymerase chain reaction (PCR) as belonging to the Bacillus genus. The analysis of 16S ribosomal deoxyribonucleic acid (rDNA) nucleotide sequence of isolate M72 showed 99 percent similarity to Bacillus toyonensis strain BCT-7112 and was deposited in the GenBank as Bacillus toyonensis strain AEMREG6 with accession number KP406731. Likewise, the 16S rDNA nucleotide sequences of isolates M69 and M67 showed 98 percent sequence similarity to Bacillus licheniformis strain W7 and Bacillus algicola strain QD43 respectively; and M67 isolate was subsequently deposited in the GenBank as Bacillus sp. AEMREG7 with accession number KF933697.1. The results of the nutritional requirements and fermentation conditions revealed that optimum inoculum size for REG-6 production was 4 percent (v/v), while 5 percent (v/v) and 3 percent (v/v) were most favourable for MBF-W7 and MBF-UFH production respectively. Glucose was the best carbon source for the production of bioflocculants (REG-6 and MBF-UFH) by Bacillus toyonensis AEMREG6 and Bacillus sp. AEMREG7 respectively, while maltose supported optimum bioflocculant (MBF-W7) production by Bacillus specie. Inorganic nitrogen (NH4NO3) was the favoured nitrogen source for both REG-6 and MBF-W7 production, while mixed nitrogen sources [yeast extract + urea + (NH4)2SO4] supported the maximum production of MBF-UFH. The initial medium pH for REG-6 was 5, while MBF-W7 and MBF-UFH were both maximally produced at the initial pH of 6. After a 96 h cultivation period under optimal culture conditions, 3.2 g of purified REG-6 with a maximum flocculating activity of 77 percent was recovered from 1 L fermented broth of Bacillus toyonensis AEMREG6. Yields of 3.8 g and 1.6 g pure bioflocculants with the respective highest flocculating activities of 94.9 percent and 83.2 percent were also obtained from 1 L, 72 h-fermented broths of Bacillus licheniformis and Bacillus sp. AEMREG7 respectively. Furthermore, all the three bioflocculants (REG-6, MBF-W7 and MBF-UFH), displayed thermal stability within the temperature range of 50 to 100 oC, with strong flocculating activities of over 80 percent against kaolin suspension over a wide range of pH range (3–11) and relatively low dosage requirements of 0.1-03 mg/ml in the presence of divalent cations in the treatment of kaolin clay suspension and Thyme River waters. Chemical composition analyses of the bioflocculants showed them to be glycoproteins with a predominantly polysaccharide backbones as shown by the following carbohydrate/protein (w/w) ratios: 77.8 percent:11.5 percent (REG-6); 73.7 percent:6.2 percent (MBF-W7) and 76 percent:14 percent (MBF-UFH).

Furthermore, all the three bioflocculants (REG-6, MBF-W7 and MBF-UFH), displayed thermal stability within the temperature range of 50 to 100 oC, with strong flocculating activities of over 80 percent against kaolin suspension over a wide range of pH range (3–11) and relatively low dosage requirements of 0.1-03 mg/ml in the presence of divalent cations in the treatment of kaolin clay suspension and Thyme River waters. Chemical composition analyses of the bioflocculants showed them to be glycoproteins with a predominantly polysaccharide backbones as shown by the following carbohydrate/protein (w/w) ratios: 77.8 percent:11.5 percent (REG-6); 73.7 percent:6.2 percent (MBF-W7) and 76 percent:14 percent (MBF-UFH).

- Description: Learning together in mediated voluntary networks can mobilise skills and innovations that help to facilitate learning and uptake of rainwater harvesting and conservation practices. It boosts extension capacity while at the same time growing farmer capabilities, tapping on the distributed cognition. These practices help to heal wicked problems of drought and global change challenges affecting marginalised farmers in South Africa. South Africa has water, nutrition and food security challenges, especially the Eastern Cape Province where there is a relatively high level of poverty. These challenges place heavy pressure on the agricultural sector as it is the main user of the allocated water in the country. In this paper, the learning of and agency for rainwater harvesting and conservation practices are explored as responses to these challenges. Despite existing cultural histories of such practices among the amaXhosa people, information on these practices is not readily available to small-scale rural farmers who thus struggle for the want of knowing. This research forms part of a Water Research Commission project, Amanzi for Food, whose intention is to mediate collaborative and co-engaged learning among networked farmers, extension workers, researchers and agricultural educators through course-mediated use of Water Research Commission rainwater harvesting and conservation materials.

- Description: “All religions emphasize the need to support charity, welfare and the disadvantaged. Obligatory giving is, thus, a manifestation of spirituality. This is why religious communities are capable, like no other sector of society, of mobilizing enormous resources for poverty alleviation and development initiative” (Maharaj & Chetty, 2007:82). Most African countries are faced with serious and worsening poverty (Wogaman, 1986:47), and one of greatest issues that demands our immediate attention within the church and society is poverty alleviation. Wogaman (1986:47) further argues that the increase in production has not served to bridge the great historic chasm between rich and poor. Hence, the church needs to direct its attention and its activity to poverty alleviation so that it becomes an advocate for the poor. Lawrence (2012:1) argued that we are created for fellowship with other people and also depend on God for our survival. Therefore, poverty touches all of God’s creatures and not simply those who experience it directly. Poverty prevents human beings from realizing their potential; it creates barriers of inequality between people, and bars people from experiencing the abundance of God’s creation.

- Description: In 2014 South Africa celebrated 20 years of democracy, and for many of the ‘Born Frees’ – those who came of age politically after 1996 – this was their first opportunity to vote in national elections. With democracy came the promise for South Africa's marginalised majority of voice and agency, but also the implicit promise that their democratically elected government would listen to them. In addition, the South African media have long championed their role as a voice for the voiceless. This article presents work done with youngsters from South Africa's poorest province, the Eastern Cape, in an effort to listen to their experience of politics and to understand their use of the media – especially whether it enables them to speak out and be heard in the public sphere.

- Description: While wastage of materials has become a serious problem requiring urgent attention in the Nigerian Construction Industry, cost overrun is a problem, which affects 90 percent of the completed projects in the world; the argument on how to reduce/eliminate cost overrun has been on-going for the past 70 years; as the on-site wastage of materials leads to increases in the final project cost. Studies from different parts of the world have shown that construction-material waste represents a relatively large percentage of the production costs. Consequently, as a result of low levels of awareness, the Nigerian construction industry pays little attention to the effects of generated material waste on cost overruns. Thus, this research aimed to investigate the relationship between material waste and cost overrun in the Nigerian construction industry. A comprehensive review of the related literature revealed that all material waste causes are related to cost overrun causes at both pre-contract and post-contract stages of a project; but not vice versa. The mixed method (quantitative and qualitative) approach that is rooted in the positivist paradigm was adopted for this study. Abuja, the federal capital territory of Nigeria was the selected geographical scope of this research, out of which thirty-one (31) construction projects were purposeful selected (projects to the value of 100 million Rand/1.6 billion Naira and above).The research instrument was an interview guide used in conjunction with a tick box. Other sources of data included field investigation (measurement of onsite material waste) and the collection of archival records from bills of quantities, project records, and specifications. Analyses of the findings lead to the conclusion that a relationship exists between material waste and cost overrun; at the pre-contract and at the post-contract stages of a project. The implication is that an increase in material wastage on-site leads to a corresponding increase in the amount of cost overrun, regardless of the percentage allowance for material waste in the process of bill preparation. The study also concluded that the average percentage contribution of material waste to project-cost overruns is four (4) percent. Material-waste sources, causes, and control measures were found to have significant effects (very high, high, medium, low, and very low), in causing or minimising cost overruns at both pre-contract and post-contract stages of projects. The research has developed a conceptual model for the management of material waste and cost overruns in the construction industry based on the results and informed by the theoretical framework. The research has also developed a mathematical model for quantifying the amount of material waste to be generated by a project; as well as a mathematical equation for the effective management of material waste and cost overrun for projects. The study has achieved its aim of establishing an understanding of the issues leading to the relationship between material waste and cost overruns, as well as their management in the Nigerian construction industry. The study recommends that the management of material waste and cost overrun should be revised, based on the findings of this research and included as part of the procurement process. The mathematical models for quantification of onsite material waste, and the mathematical equation for managing material waste and cost overruns developed in the study, could be usefully adopted to improve management of material waste and cost overrun in the Nigerian construction industry.

- Description: The nursery role hypothesis provides an approach for assessing the nursery function of habitat types within estuaries. This study attempted to assess the nursery value of the dominant estuarine habitats in the Bushmans Estuary for Rhabdosargus holubi (Steindachner 1881) by analysing habitat complexity, relative abundance and behaviour of R. holubi and using stomach contents analysis and dietary diatom composition as indicative of feeding habitat. Structural habitat complexity was assessed in Zostera capensis (Setchell) seagrass and Spartina maritima (Curtis Fernald) salt marsh by sampling above-ground stem density and length, and total cover per unit area (Ct/At). Dimensionless habitat complexity indices such as the interstitial spatial index (ISI) at three magnifications and fractal geometry at two magnifications were used to further analyse habitat complexity. Above-ground biomass (P<0.05) in each season and canopy height (P<0.001) were significantly higher in salt marsh than in seagrass whilst stem density was significantly higher in seagrass than in salt marsh in each season (P<0.001). Each dimensionless index indicated that complexity is notably higher in seagrass than in the salt marsh. Using dimensionless indices that analyse complexity at different spatial scales provided a better analysis of habitat complexity than canopy height and biomass as it allowed for direct comparisons between habitat types. Underwater video cameras were deployed in seagrass, salt marsh and sand flat habitats to assess the relative abundance and behaviour of R. holubi. The relative abundance of R. holubi was significantly higher in seagrass than salt marsh and sand flats, whilst the behaviour of R. holubi indicated a high degree of habitat use in structured habitats and a low degree of habitat use in unstructured sand flat habitats. This indicated that not only are juvenile R. holubi a vegetation-associated species, but also a species that prefers seagrass to salt marsh.

- Description: This study is a psychobiographical study aiming to explore and describe the life of Theodore Robert Bundy, a serial killer who confessed to approximately 30 homicides committed in various states of America between 1974 and 1978. The study used Erik Erikson’s theory of psychosocial development to examine Bundy’s life and to understand his unique character and personality development. The subject was chosen based on interest value through purposive sampling and the study utilises a qualitative single case study approach. Archival data were collected from primary and secondary sources in order to enhance the trustworthiness and credibility of the study. All materials collected and analysed, were published and publically available. Data were analysed by first organising and reducing the information obtained, and then displaying it for a discussion of Bundy’s life. Themes of discussion centred around Bundy’s lack of resolution of psychosocial crises and the development of malignancies and maladaptations which impacted negatively on his later development and identity formation. The study emphasises the importance of psychobiographical research studies and the value of Erikson’s theory of psychosocial development in understanding personality development. Recommendations for future research in this field were made in the hope of further uncovering and understanding personality and its development.

Shifting identities: An exploration of the possibilities for a syncretic Afrikaans theatre by means of three case studies – Hex (2003), Lady Anne (2007), Ekspedisies (2008)

- Description: This thesis investigates the possibilities for syncretic Afrikaans language theatre within a post-1994 South African society. The research sets out to explore in what manner theatre can be language-specific, while at the same time being able to cross language contexts. This exploration is driven by the wish to develop strategies for creating Afrikaans theatre that is able to reflect on a society “united in diversity”. In this regard it is argued that for theatre to be able to both retain and cross language barriers, processes of bonding and bridging are necessary. The thesis sets out first to explain why these processes are required and then to suggest ways in which such processes can be implemented in practice. A triangular approach is used, in which conceptual and theoretical frameworks are developed to reflect on actual theatre practices. Three of my own productions are used as case studies, namely Hex (2000; 2003), Lady Anne (2007) and Ekspedisies (2008). These productions can be understood to be “boundary objects” in Henk Borgdorff’s (2012: 177) sense of the word, in that they fulfil a dual function: they are artistic productions that can also be reconstituted to serve a research purpose beyond the productions themselves. All three works were first created for public consumption before becoming cases for this thesis. Many of the strategies that were developed and tested in creating these productions are examples of ways in which bonding and bridging in Afrikaans language theatre can be understood. Chapter One of the thesis contextualises the political currents and events that necessitated the impulse towards “bonding and bridging”. In this case the political and ethical impetus behind the practical explorations has been related predominantly to the democratisation of South African society, in which a paradigm shift happened from viewing the Afrikaans language as one over many to one amongst many. Within a multilingual South Africa, concerns are raised about ways in which to create theatre in South African languages other than English (often understood to be the only possible bridging language) that are able to cross language divides. Following this introduction to language-related concerns, Chapter Two explains how the shift from apartheid to democracy made space for shifts in identity – on personal as well as institutional levels: a progression from essentialised notions of culture to the celebration of plurality. This progression is then related to theatre, with an explanation of how the post-1994 theatre landscape demanded a reimagining of the form and function of theatre. In this re-imagination the notion of a “third space” is important; something that is introduced in this chapter as an alternative to polarised identity constructions. The function of the “third space” as an in-between space and a meeting point for diverse people and entities is a strong underlying theme of this thesis and it serves as a reoccurring touchstone to the ideas put forward. Chapter Three discusses the South African arts festival culture and its contribution to the South African theatre landscape. Particular focus is placed on the Klein Karoo National Arts festival (KKNK) as a platform for the development of the Afrikaans language within a post-1994 context. What is emphasized in particular is the attempt by the KKNK festival to be linguistically and culturally exploratory and inclusive in the face of language protectionism. After the contextual background of the first three chapters, the thesis shifts to an analysis of theories related to “hybridity” and “syncretism”. In Chapter Four the argument is put forward that of the various inclusive performance and theatre models that represent a multicultural society, the most responsive forms are those that are syncretic and hybrid. Principles that can contribute to the unification and merging of diverse and polarized societal groups are described, and suggestions are made for possible ways to bring about bonding and bridging within cultural practices. Having introduced these principles, examples are offered of how these theories might be understood in other disciplines, namely, religious studies, anthropology, history and a range of cultural practices. Following this broad discussion, Chapter Five describes syncretism and hybridity more specifically in theatre by means of relevant examples. Taking the discussion further into the realm of application, Chapter Six offers an overview of “workshop theatre”, “translation” and “collage making” as strategies for putting theories of hybridity and syncretism into practice. This is followed (in Chapters Seven, Eight and Nine) by a discussion of the three productions (Hex, Lady Anne and Ekspedisies) as case studies that demonstrate how these theories can be understood in practice. Practical strategies for bridging language divides are foregrounded, such as code switching as an approach for enabling a “co-habitation” of languages; physical theatre as a means for crossing language divides; and the creation of more than one language version of a production as a tactic to accommodate shifting contexts. Following on from the discoveries made in the foregoing chapters, I conclude that theories and practices related to notions of “third space”, “hybridity” and “syncretism” are ideal for creating theatre forms (in the Afrikaans language in particular) that can truly reflect a South African society which is “united in diversity”. The thesis ends by offering suggestions for ways in which new, future identities, can be developed.

Practical strategies for bridging language divides are foregrounded, such as code switching as an approach for enabling a “co-habitation” of languages; physical theatre as a means for crossing language divides; and the creation of more than one language version of a production as a tactic to accommodate shifting contexts. Following on from the discoveries made in the foregoing chapters, I conclude that theories and practices related to notions of “third space”, “hybridity” and “syncretism” are ideal for creating theatre forms (in the Afrikaans language in particular) that can truly reflect a South African society which is “united in diversity”. The thesis ends by offering suggestions for ways in which new, future identities, can be developed.

- Description: The Republic of South Africa (RSA) became a democracy when the African National Congress (ANC) came to power in 1994. However, more than twenty years after the apartheid era, the people of the RSA are highly politicised and society still shows an extremely high level of inequality in income that is aggravated by the lack of formal job opportunities in the country. Disturbingly, early-stage entrepreneurial activity in the RSA declined from 7.8 percent in 2008 to 5 percent in 2009. As a result, the low levels of entrepreneurial activity are partly responsible for the stagnation in the structural transformation of the economy. The economy remains dependent on sectors such as agriculture and mining where looting, instability, violence and rent-seeking are endemic in spite of plentiful natural resources. As a consequence of these factors, manufacturing is becoming increasingly uncompetitive and the economy is becoming increasingly less innovative. The RSA‟s government leaders should have used the strengths of the country to minimise or rectify the weaknesses of the extremely high levels of inequality in income and the lack of formal job opportunities. Instead, these leaders identified their supporters, satisfied their short-term consumption demands, distributed jobs to the party faithful and provided social welfare to the poor. Additionally, the majority of school leavers are not pursuing tertiary studies but, with limited or little education, they still have to form part of the potential labour force of the future. The youth employment rate for 15 to 24 year-olds, in the RSA, is as low as 12.5 percent. Again, this highlights the importance of finding alternative ways to increase the population‟s participation in the economy, probably through some form of entrepreneurship. The purpose of this study was to develop a theoretical model with the main objective being to identify the factors (variables) that will promote growth, sustainability and good governance in Christian-owned Small, Micro and Medium Enterprises (SMME) within the RSA. Business is commonly viewed as a secular pursuit and religious people, particularly in Western societies, have a narrow view of the conceptual and practical application of their faith and spirituality in their businesses. As a result, the potential of businesses to influence communities, particularly with regard to issues such as social iniquities and cultural reform, good governance, responsible business behaviour, social capital, spiritual intelligence (SQ) and Christian entrepreneurship orientation appear to be, at worst, more or less irrelevant and, at best, greatly under-valued and under-utilised. The intersection of these constructs provides an understanding of how an entrepreneur‟s heightened consciousness in terms of his/her personal values and beliefs can affect his or her business activities and crucial characteristics of the entrepreneurial process, such as the recognition of opportunities, the creation of new ventures, as well as the operation and growth of these business ventures. This study uncovered a number of themes that shed light on how Christian SMME owner-managers rationalise the everyday dealings of their business lives as an expression of their faith. This study is an expression of a complex phenomenon that is extremely relevant in the present day and sharpens the focus on the important role that religious faith has to play in the field of business outcomes. Many Christian entrepreneurs express a motivational need to give back to their communities, customers and other stakeholders of the business venture. Christian entrepreneurs value intrinsic factors like purpose, passionate work and personal calling above wealth, fame, power, money, and recognition. A combination of Christian character traits forms the backbone of a Christian‟s internal power and purpose. God created people to glorify Him and this purpose is achieved through the fulfilling of a personal calling. A calling is often accompanied by a conviction of divine influence and the vocation in which one customarily engages. The call to the Christian entrepreneur is to be the salt and light in an environment (Mathew 5:13) like RSA, that is not conducive to entrepreneurial behaviour, where unemployment is very high, infrastructure is buckling under the pressures of bad management and corruption is rife.

- Description: Brewery effluent (BE) needs to be treated before it can be released into the environment, reused or used in down-stream activities. Current technologies used to address this concern at the experimental wastewater treatment plant at Ibahyi Brewery (SAB Ltd) include anaerobic digestion (AD), primary facultative ponds (PFP), high rate algal ponds (HRAP) and constructed wetlands (CW). The aim of this work was to determine if BE treated in these systems might be suitable for crop irrigation. A test crop, cabbage (Brassica oleracea cv. Star 3301), grew best on post-AD and post-PFP BE compared to those irrigated with post-HRAP or post-CW effluent. However, the yield was 13% lower than cabbage plants irrigated with a commercial nutrient solution and fresh water. The relatively high conductivity (3019.05 ± 48.72 μs/cm2) of BE may be the main factor reducing the cabbage yields. Post-HRAP and post-CW BE were the least suitable for irrigated crop production due to the higher conductivity and lower nutrient content of these treated effluents. After three months, soils irrigated with post-AD and post-PFP BE had a significantly higher sodium content and sodium adsorption ratio (3919 ± 94.77 mg/kg & 8.18 ± 0.17) than soil irrigated with a commercial nutrient solution (920.58 ± 27.46 mg/kg & 2.20 ± 0.05; p<0.05). However, this was not accompanied by a deterioration in the soil’s hydro-physical properties, nor a change in the metabolic community structure of the soil (p>0.05). After prolonged irrigation with treated BE, sodium is likely to build up in the soil and this can be expected to be accompanied by a deterioration in the soil physical structure. However, crops species such as millet (Echinochloa esculenta), lucerne (Medicago sativa) and saltbush (Atriplex nummularia) reduced the build-up of sodium in the soil. The results suggest that sodium was mainly removed from the soil through plant-assisted leaching. Of the crops grown, lucerne showed the most promise because it improved the soil physical properties, is able to grow well in alkaline environments, is a popular fodder crop and can be harvested multiple times from a single stand. Brewery effluent is more suitable for soil production systems than hydroponic production systems because the soil was able to act as a buffer against the high pH of post-AD BE, whereas in a hydroponics systems the high pH reduced the availability of key minerals to plants. In conclusion brewery effluent contains sufficient plants nutrients to support the growth of cabbages, saltbush, lucerne and millet. However the sodium content of BE is a concern as it accumulates in the soil, and in the long-term it may lead to soil degradation. It is suggested that the brewery change the pH neutralising treatment of BE from sodium hydroxide to potassium hydroxide, or dolomitic lime (calcium and magnesium carbonate) because this would reduce the introduction of sodium into the system, and would increase the suitability of BE for crop production, given potassium and calcium are plant nutrients. The benefits of developing this nutrient and water resource could contribute to cost-reductions at the brewery, more efficient water, nutrient and energy management, create job opportunities with the potential of improving food security in the local community.

- Description: Disorders of lifestyle are increasing globally; countries in transition are suffering the double burden of both contagious and chronic disorders. The utilization of health education to address these issues has had variable results, but the most successful have incorporated human contact. The aim of this study was to measure the quantitative and qualitative impact of a wellness promotion programme on university students. The objective was to provide a structured facilitated holistic wellness education programme to a sample of socioeconomically disadvantaged students in Higher Education in the Eastern Cape Province, South Africa. Using a pragmatic mixed methodological approach to this critical evaluation, the impact on both wellness and academic progress was measured. Initial demographic data was gathered via a biographical questionnaire, pre- and post-intervention measurement of wellness, using the Wellness Questionnaire for Higher Education, as well as a semi-structured qualitative questionnaire and transcripts of academic results. Quantitative data was analysed using SPSS analysis software and qualitative data using the NVivo analysis package. The findings were that all students improved throughout the year in their overall wellness scores, in particular in areas such as avoiding excessive sun exposure and increasing the amount of physical exercise. This corresponded with an increase in the value that the participants attached to information on these aspects of wellness, which was attributed to the programme. Results revealed that there was a weak correlation between student wellness measured at the year-end and academic success overall, but a strong correlation between student wellness and academic success for the students that gained the highest marks. Analysis of the dimensions of wellness that correlated best with student success revealed that there was a particularly strong correlation between year-end career wellness and year-end academic success. In conclusion it was found that a positive and holistic salutogenic wellness education programme increased levels of student wellness overall, which translated into student academic success. The link between wellness and success was particularly strong in students that gained higher marks. Recommendations include that first-year higher education students receive a positive wellness education programme built into the curriculum of their first year of study and that the overall impact be monitored across a broader spectrum of students over the duration of their diploma or degree programme.

- Description: There has been an increasing concern about animal welfare in small-scale farming as the farmers' agricultural practices shift towards intensive agriculture. It has become important to comprehend how small-scale farmers perceive and practice animal welfare relative to production and market integration. To solve the research problem, the research emphasis was on assessing the following practices; procedures adopted by the small-scale farmers, welfare levels verses industry equirements for market integration; determinants affecting small-scale perceptions and attitudes towards animal welfare and how has animal welfare affected farm development and production. The research focus for this study was to investigate the linkage between perceptions and this process. In order to achieve a more in-depth understanding of the study while also ensuring its validity and correctness a triangulation research method was applied, which consisted of a quantitative and qualitative method approach. The focus groups and structured research interview questions were used as the main data collections instruments. The study consisted of sixty-two piggery small-scale farmers from three areas of the Nelson Mandela Bay metropole. The study found that there was a disparity between the perceptions and practice of small-scale farmers. Farmers perceived their practices as acceptable. However, on most of the farms the pigs were farmed in an unhygienic environment, had limited handling facilities, the farmers had unconventional methods to handle the pigs; there was poor support from technical services, many of the farmers never administered animal welfare evaluations and applied questionable feeding practices. The study also indicated that less than 15% had suitable facilities to accommodate suitable reproduction and piglet care. The researcher recommended the following interventions to improve animal welfare approaches with small-scale farmers in the Nelson Mandela Bay metropole: Training and information campaigns to improve small-scale piggery farmers' perception and knowledge of animal welfare, as well as market standards and requirements. Strengthening the relationship between the small-scale piggery farmers and animal welfare stakeholders. Including active engagement between small scale piggery farmers and the Department of Rural Development, Agrarian Reform and Urban Agriculture Unit of the Nelson Mandela Bay Municipality. Encouraging farmers to strive for stronger markets to facilitate better income and care of animals.

- Description: In South Africa, mental health care is being integrated into primary health care services. The integration of services was aimed at increasing the accessibility and availability of all health care services at primary health care level. The integration was well intentioned, and it was hoped that mentally ill clients would benefit from having a service near their homes. However, the process of integration is fraught with challenges, for instance, staff shortages, which lead to ineffective nursing management of mentally ill clients at the primary health care clinics. As a result, one professional nurse is often allocated to manage the clinic services on a daily basis with the assistance of an enrolled nurse or auxiliary nurse. The professional nurses therefore experience high levels of stress due to gross staff shortages and lack of time to conduct proper nursing assessments. This led to the research question: “What are the experiences of professional nurses with regards to the nursing management of mentally ill clients in rural primary health care clinics in the O.R. Tambo District in the Eastern Cape?’’ The proposed objectives of the study were to explore and describe the experiences of professional nurses working in rural primary health care clinics with regard to the nursing management of mentally ill clients. The researcher thereafter made recommendations to the district managers regarding effective nursing management of mentally ill clients in rural primary health care clinics. A qualitative, exploratory, descriptive and contextual design was used. The research population comprised of professional nurses working in rural primary health care clinics in the O.R. Tambo District in the Eastern Cape. Purposive sampling was used to identify participants and the sample number was determined by data saturation. Unstructured interviews and observation notes were used to collect data. The eight steps of data analysis suggested by Tesch were utilized to analyze the data. The researcher conducted an in-depth literature review in order to identify research gaps pertaining to the study. To ensure that a high level of validity and reliability was exercised throughout the study, the researcher conformed to Lincoln and Guba’s model of trustworthiness. The study was conducted in an ethical manner and ethical principles were adhered to. Findings: Three themes with subthemes emerged. The study showed that professional nurses experienced challenges related to the nursing management of mentally ill clients. These challenges included shortage of staff, a heavy workload, and lack of resources, lack of in-service training and workshops related to mental health issues coupled with lack of support from the supervisors. Due to the challenges, the mentally ill clients were not getting quality nursing care leading to complications and relapse. Conclusion: It emerged from the study that matters pertaining to mental illness and mental discomfort were still a serious problem in rural areas. The problems were related to the challenges which prevented professional nurses from providing quality nursing care to mentally ill clients with subsequent complications and relapse. Recommendations: Recommendations were made as an effort to ensure that the nursing management of mentally ill clients in rural primary health care clinics is improved. These recommendations were categorized as related to nursing practice, nursing education and nursing research.

- Description: Pitched is a novella made up of short stories. It is about breaking in, breaking down and breaking out of the advertising industry. My protagonist loves and hates this confusing world she lives in. She is tough but also emotional and anxious, often trapped between her strong desires and her strong morality. She finds herself both attracted to and repulsed by the people who inhabit this world - sexy wolf-like men, and prickly female execs alike. I have been inspired by the work of Lidia Yuknavitch, Kate Zambreno, Michelle Tea and Chris Kraus to create a universal woman I can identify with.
