- 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: Criticisms about the safety of biological control of alien plants has resulted in a risk-averse approach, where the risks posed by the agent are paramount and the risks posed by the alien plant are neglected. We argue that the risk associated with non-target damage from agents needs to be assessed relative to that of their target alien plants. A literature review of the non-target risks associated with biological control agents was undertaken in terms of the risk to native species from agents relative to the risk to native species from their alien plant targets. We then developed a framework that compares the consequence with the likelihood of non-target damage for both agents and their targets to provide an overall risk rating. Assessments of the risk of damage from both agents and their target alien plants will enable researchers, managers and policy makers to better assess the risks from biological control.

- 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.

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.

- Description: The focus of this study was to explore Clothing Fashion Design students’ workplace learning experiences at one university of technology in Zimbabwe. Underpinned by Kolb’s (1984) experiential learning theory, the study was located in the interpretivist research paradigm and followed a qualitative research approach, which utilised a descriptive case study design. The research sample was purposively drawn from third year Clothing Fashion Design students on workplace learning, university lecturers and workplace mentors. It included nine third year students, six workplace mentors and six University lecturers. Two major methods were employed to collect data namely; in-depth face–to-face individual interviews with students, university lecturers and workplace mentors and document analysis as a secondary method of data collection method. The data were analysed for content using thematic data analysis technique. Major findings of the study are that third year Clothing Fashion Design students at the University under study applied knowledge and skills learnt from University in Pattern Design, Garment Cutting and Making, Fashion Illustration, Fashion marketing and Retailing and Communication Skills. However, they did not design new patterns neither were they guided in Fashion Illustration since these were not done in industry as mentors lacked knowledge in these critical areas. In garment cutting and making they did not use specialised machinery due to the scarcity of such machinery and in other cases limited access. Knowledge and skills acquired from workplace learning included pattern design, garment cutting and making, fashion quality management and fashion marketing and retailing. Students did not gain skills in fashion designing and use of specialised machinery since most industries had no such machinery. Students also learnt to value time and put emphasis on production of quality products at the workplace. Dress was also valued but not by all the students since it was not uniformly considered in all industries. The factors that hindered workplace learning included strikes by mentors, shortage of material resources such as fabrics, under qualified mentors, sexual harassment and improper supervision, financial challenges and inadequacy of time to attend to university academic work. Factors that promoted workplace learning included assistance by mentors, availability of basic resources for use, good student-mentor relationships and self- motivation. Findings also reflected the guidance that was offered to students by lecturers and workplace mentors which included preparation of students for workplace learning, discipline, counselling and guidance in research projects and in practical work. Support that was offered to students by lecturers and workplace mentors included assessment, moral support, student welfare and, in some cases material support. There was very little of financial support. The study concludes that while students generally appeared to benefit from workplace learning, there were challenges that negatively affected workplace learning. The study recommends improved university/industry partnership to enhance workplace learning, among other recommendations. A model for enhancing students’ workplace learning is also proposed.

- Description: Floods are water induced disasters that led to temporary induction of dry and cause serious damages in the affected location such as loss of valuable assets, lives and destruction of infrastructure. Flooding had become common in Alexandra Township during rainfall season and the recorded impact of periodic flooding on communities is increasing at an alarming rate. This study seeks to identify populations vulnerable to flooding and to map-out areas at high risk of flood disasters, using GIS and RS as a tool. For GIS application different types of maps were produced, namely, flood vulnerability, hazards, risk and risk index map highlighting areas at risk of being affected by flooding. Flood risk index maps identify three categories of risk zones; low and high risk zone. The household units within each of the risk zones was calculated and the total was estimated to be 762 for low-risk and 32 486 for high risk zone. The SRTM Digital Elevation Model (DEM) and multi-temporal Satellite Probatoire d’Observation de la Terra (SPOT) satellite images for 1997, 2006 and 2013 of the area was used for land-use and land-cover (LULC) change analyses using maximum-likelihood post-classification comparison. Results reveal that tremendous urban development had taken place in the study area along the Jukskei River area for the past sixteen years. It was observed that there was a sharp decrease in vegetation from 237ha (1997) to 134ha (2006) to 68ha (2013). This may had a negative impact on the environment around this area by decreasing surface runoff. The trend however, shows that bare surface and vegetation land-cover class has no potential to recover. Questionnaires aimed at all the residents in the study area were used to assess the effect of periodic flooding on communities. Community leader and City of Johannesburg Disaster Management Unit (CoJDMU) interviews were also conducted to get more insight about floods management in the study area. Finally, strategies for alleviating flood risk in the study area were discussed and some recommendations were made to help the government and municipal authorities to improve and development sustainable flood mitigation measures.

- Description: This study used cross-sectional survey data to estimate farmers` perceptions of, and commonly cultivated ILVs, factors that influence the participation of smallholder famers in the production of Indigenous Leafy Vegetables and its contribution to household food security]. With regard to farmers` perceptions of ILVs, descriptive results reveal that a majority of the people from the study area share positive perceptions with respect to ILVs. Regression estimates for determinants of participation indicate that the production of ILVs is primarily conditioned by shared perceptions and institutional factors rather than the socio-economic attributes of farmers. Public policies that address the institutional framework (extension, credit, market and social networks) in favour of ILVs are more likely to promote production. Also, more research on the documentation and benefits of ILVs, supported by investments targeting educational campaigns towards promoting positive attitudes and dispelling fears and myths surrounding ILVs, will further promote production. With reference to the contribution of ILVs to food security, descriptive results indicate that participation in the production of ILVs leads to a higher HDDS and a lower HFIAS. Regression estimates further revealed that participation positively contributes to a higher HDDS and a lower HFIAS, suggesting that households who participate in the production of ILVs are more likely to be food secure than non-participants. Therefore, participation in the production of ILVs has significant potential to address household food security.

- Description: The focus of this study was on how Grade 10 Physical Sciences learners make sense of resultant vectors. During my experience over more than 10 years as a Science teacher in Matatiele in the Eastern Cape Province I found that Grade 10 Physical Sciences learners consistently struggled to work with resultant vectors. Many studies have shown that learners in similar contexts are generally not doing well in Science. An interpretive paradigm was used in this study, focusing on the individual or a specific group in a qualitative case study approach and a social constructivist perspective. The unit of analysis was on how Grade 10 Physical Sciences learners make sense of resultant vectors. A diagnostic test, observation and videotaped lessons, learners’ workbooks, summative test and stimulated recall interviews were used to gather data. The data were analysed inductively using a thematic approach and in relation to the main research question: How do Grade 10 Physical Sciences learners make sense of resultant vectors? The data were validated through watching the videotaped lessons with the teacher who had been observed teaching vectors. Also, transcripts of the interviews and a summary of discussions were given back to the teacher whose learners had been observed to verify the learners’ responses and check for any misconceptions. It was found that linking scientific concepts to learners’ prior knowledge enabled them to learn in a relaxed and non-threatening environment. In doing so, sense making of resultant vectors was possible. The study thus recommends that teachers should be supported in their endeavours to help learners make sense of scientific concepts during teaching and learning situations. Some language related challenges that were also encountered warrant further research.

- Description: We describe MARS (Motif Assessment and Ranking Suite), a web-based suite of tools used to evaluate and rank PWM-based motifs. The increased number of learned motif models that are spread across databases and in different PWM formats, leading to a choice dilemma among the users, is our motivation. This increase has been driven by the difficulty of modelling transcription factor binding sites and the advance in high-throughput sequencing technologies at a continually reducing cost. Therefore, several experimental techniques have been developed resulting in diverse motif-finding algorithms and databases. We collate a wide variety of available motifs into a benchmark database, including the corresponding experimental ChIP-seq and PBM data obtained from ENCODE and UniPROBE databases, respectively. The implemented tools include: a data-independent consistency-based motif assessment and ranking (CB-MAR), which is based on the idea that `correct motifs' are more similar to each other while incorrect motifs will differ from each other; and a scoring and classification-based algorithms, which rank binding models by their ability to discriminate sequences known to contain binding sites from those without. The CB-MAR and scoring techniques have a 0.86 and 0.73 median rank correlation using ChIP-seq and PBM respectively. Best motifs selected by CB-MAR achieve a mean AUC of 0.75, comparable to those ranked by held out data at 0.76 { this is based on ChIP-seq motif discovery using five algorithms on 110 transcription factors. We have demonstrated the benefit of this web server in motif choice and ranking, as well as in motif.

- Description: Plants have been an important part of medicine and since the existence of human beings; they have been used to cure a variety of ailments such as diarrhoea, wounds and sexually transmitted diseases. Far from being out-dated, the use of traditional medicinal plants plays a significant role in drug discovery and remains a source of medicine still used by many South Africans. Diseases of the urinary tract can be treated using traditional medicinal plants. Although most cases of urinary tract infections (UTIs) are acute and uncomplicated, a few cases do become chronic and complicated. Resistance of pathogens causing UTIs to antibiotics normally used for treatment is one of the reasons for infections developing into the chronic and complicated state. In this study, medicinal plants indigenous to South Africa and traditionally used to treat UTIs were investigated in vitro for antimicrobial activities against UTI-causing pathogens. The plants investigated were Bulbine latifolia, Eucomis autumnalis, Hypoxis hemerocallidea and Trichilia dregeana. American Type Culture Collection (ATCC) microbial strains together with clinical strains were tested against distilled water, methanol and acetone extracts of the plants. The microbial strains included Enterococcus faecalis, Staphylococcus saprophyticus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa and Candida albicans. The agar well diffusion method was used to screen for antimicrobial activity; the microtiter dilution method to determine the minimum inhibitory concentration; and thin layer chromatography fingerprints to separate the mixtures of the extracts and determine the number of active compounds. The study also investigated the scientific rationale for the traditional use of plant combinations to treat diseases. Three plant combinations (1:1) were investigated for potential interactive properties, which were identified through the sum of the fractional inhibitory concentration index (ΣFIC) calculations. The plant combinations studied were Hypoxis hemerocallidea and Bulbine latifolia; Hypoxis hemerocallidea and Eucomis autumnalis; and Hypoxis hemerocallidea and Trichilia dregeana. In the study, more activity was observed in the microtiter dilution method as compared to the agar well diffusion method. This was true in both the studies of the plants independently and the combination studies. The independent plants displayed noteworthy MIC values (≤ 2 mg/ml) against E. coli, Kleb. pneumoniae, P. mirabilis, P. aeruginosa and C. albicans. The plant combinations studied did not show any synergistic interactions (ΣFIC ≤ 0.5). Only non-interactive (ΣFIC >1.0 - ≤4.0) and additive (ΣFIC >0.5-1.0) interactions were observed. The study contributes to the on-going investigation of antimicrobial activities of medicinal plants and highlights the need for further investigations on the synergistic interactions of the medicinal plants used in this study.

- Description: The ever-widening scope and range of global change and interconnected systemic risks arising from people–environment relationships (social‐ecological risks) appears to be increasing concern among, and involvement of, citizens in an increasingly diversified number of citizen science projects responding to these risks. We examined the relationship between epistemic cultures in citizen science projects and learning potential related to matters of concern. We then developed a typology of purposes and a citizen science epistemic‐cultures heuristic and mapped 56 projects in southern Africa using this framework. The purpose typology represents the range of knowledge‐production purposes, ranging from laboratory science to social learning, whereas the epistemic‐cultures typology is a relational representation of scientist and citizen participation and their approach to knowledge production. Results showed an iterative relationship between matters of fact and matters of concern across the projects; the nexus of citizens’ engagement in knowledge‐production activities varied. The knowledge‐production purposes informed and shaped the epistemic cultures of all the sampled citizen science projects, which in turn influenced the potential for learning within each project. Through a historical review of 3 phases in a long‐term river health‐monitoring project, we found that it is possible to evolve the learning curve of citizen science projects. This evolution involved the development of scientific water monitoring tools, the parallel development of pedagogic practices supporting monitoring activities, and situated engagement around matters of concern within social activism leading to learning‐led change. We conclude that such evolutionary processes serve to increase potential for learning and are necessary if citizen science is to contribute to wider restructuring of the epistemic culture of science under conditions of expanding social-ecological risk.

- Description: The ever-widening scope and range of global change and interconnected systemic risks arising from people–environment relationships (social‐ecological risks) appears to be increasing concern among, and involvement of, citizens in an increasingly diversified number of citizen science projects responding to these risks. We examined the relationship between epistemic cultures in citizen science projects and learning potential related to matters of concern. We then developed a typology of purposes and a citizen science epistemic‐cultures heuristic and mapped 56 projects in southern Africa using this framework. The purpose typology represents the range of knowledge‐production purposes, ranging from laboratory science to social learning, whereas the epistemic‐cultures typology is a relational representation of scientist and citizen participation and their approach to knowledge production. Results showed an iterative relationship between matters of fact and matters of concern across the projects; the nexus of citizens’ engagement in knowledge‐production activities varied. The knowledge‐production purposes informed and shaped the epistemic cultures of all the sampled citizen science projects, which in turn influenced the potential for learning within each project. Through a historical review of 3 phases in a long‐term river health‐monitoring project, we found that it is possible to evolve the learning curve of citizen science projects. This evolution involved the development of scientific water monitoring tools, the parallel development of pedagogic practices supporting monitoring activities, and situated engagement around matters of concern within social activism leading to learning‐led change. We conclude that such evolutionary processes serve to increase potential for learning and are necessary if citizen science is to contribute to wider restructuring of the epistemic culture of science under conditions of expanding social-ecological risk.

- Description: The world, in recent decades, has witnessed an incalculable surge in global “wicked” policy problems that have long-term, and most often irreversible, impacts, not least terrorism, climate change, biodiversity losses and desertification. Wicked problems are wicked because there is no single epistemological system that can adequately coordinate policy action for addressing them. Literature abounds with international case studies of opposition to national institutions that are designed to put into effect global and regional policies for resolving wicked problems. This raises questions about what constitutes reasonable institutions, how such institutions can be designed and why societies sometimes fail to develop such institutions despite the obvious need for them. As a point of entry into these issues, the thesis adapted and extended the Northean (2007, 2012) macro meta-theoretic framework for studying the violence-development relationship, which focuses on the role of political and economic competition in the emergence of ‘right’ institutions that promote development, while containing violence. The Northean framework conceptualises two mutually exclusive social orders – the limited access order and the open access order – which provide the socio-cultural context for the evolution of specific institutions. The macro meta-theoretic framework was transformed into a micro metatheoretic framework in such a way that the limited access order and the open access order co-existed in the evolution of specific institutions. This reconceptualisation built on Bromley’s (2004, 2006) two realms of public policy: the realm of reasons (legislative-judicial system) and the realm of rules (administrative system) as well as the feminist concept of epistemic violence, which broadened the concept of violence from being exclusively physical to including the sociocognitive. The feminist concept of epistemic oppression logically fitted into, and became a new sub-category of, Commons’ (1899, 1924, 1934) theories of sovereignty and negotiational psychology. The innovations showed that either of these realms can be a limited access order, while the other can be an open access order or both can be open access orders or both can be limited access orders. The conceptual innovations were then used as an interpretive scheme in analysing the evolution of the South African invasive alien species regulatory reforms under the National Environmental Management: Biodiversity Act of 2004, using a case study of the trout sector, which was the most opposed to the reforms. There was a general perception among socioeconomic sectors that utilise invasive alien species that the regulatory reform processes for the governance of such species had institutionally isolated the sectors. Because of this perception, the regulatory reform process was contested, and implementation of the Fifth Chapter of the Act, which deals with the governance of invasive alien species, was delayed for nearly a decade. The thesis evaluated whether institutional isolation existed and how and why it came to be since it has implications for the reasonableness of emerging regulatory institutions, economic performance of sectors and efficient allocation of fiscal resources in institutional design processes. A mixed methods methodology was used, which included data analysis techniques such as semiosis, exploratory factor analysis, econometric estimation and document analysis. Policy documents, an online survey and key informant interviews comprised the data. The findings suggested six dimensions of institutional change that a theory of institutional change might have to address: the origin and continuity of pecuniary institutions; selfreinforcing mechanisms of the limited access policymaking order; succession and disbandment of the limited access policymaking order; exclusivity of negotiations in institutional design; tiers of institutional isolation; and the role of administrative discontinuities. Findings suggested that institutional isolation existed in the regulatory process, manifesting in three forms: administrative isolation, epistemological isolation and sectoral isolation. Administrative isolation was the most complex of the three in that it also involved a less obvious process of institutional isolation in the form of administrative redefinition of opportunity sets that were already legislatively redefined. The mechanisms of institutional isolation through which administrative isolation was sustained were administrative financing of research and careerism. The two mechanisms created a revolving door-type scenario through which invasion biologists supplied the administrative agency with candidates for senior (decision making) positions and the administrative agency, in turn, demanded specific types of knowledge over which the same epistemic community had a monopoly. The revolving door-type scenario was found to ideologically and physically entrench invasion biologists into the regulatory community. The consequence of the entrenchment was institutional hegemony, which manifested itself through the mechanism of epistemic violence insofar as the invasion biologists became the epistemic arbiters about what kinds of ideas and institutions really mattered in the governance of invasive alien species. Econometric estimates suggested that the extent to which an emerging institution is perceived to be reasonable by regulated sectors depends on the extent to which the institution is designed in a participatory and inclusive manner (that is, using integrative knowledge systems), the extent to which the designers used credible evidence and contextualised international evidence as well as the extent to which the emergent biodiversity governance institution was anthropocentric. However, findings suggested that the South African regulatory reform process fell short on all these four dimensions of reasonable institutions, which is characteristic of institutional design process shaped by hegemonic social imaginaries, resulting in institutional isolation. Emerging from the findings are several theoretical insights. Bush’s (1987) concept of institutional spaces under the Veblenian Dichotomy was extended, the result of which was identification of two stable institutional equilibria – one ceremonial and another instrumental. The ceremonial equilibrium was a typical limited access policymaking order and was responsible for the historical and present emergence of regressive institutions. Findings also suggested that the entrenched invasion biologists ceremonially encapsulated the knowledge fund that had been accumulated since the 1980s, which could have facilitated the consensual design of regulatory institutions for invasive alien species without protracted controversy. Findings suggested that a limited access policymaking order could only be disbanded by the intervention of an external sovereign agent (in this case the office of the state president) since the administrative agency, and the epistemic community that advised it, adopted the solutions that were empirically tested and proposed in the 1980s only after the intervention of the external sovereign agent. The instrumental equilibrium repealed the contested prisoner’s dilemma that was characteristic of the policy process and turned it into an assurance policy game by facilitating the identification of common interests. This finding logically links the study to a recent theoretical development in institutional theory – Ordonomics – which focuses on the causality between ideas and institutions. The findings imply that it is possible to design reasonable institutions as long as integrative (transdisciplinary) knowledge systems, including the non-scientific knowledge of the resource users, are incorporated. Integrative knowledge systems facilitate semantic innovations, which create social DNA, but epistemic violence destroys social DNA. They also imply that reliance on unidisciplinary knowledge systems in institutional design induces a large and inefficient transaction cost burden of public policy on the fiscus and private agents alike because of the inevitability of controversy, especially for wicked policy problems.

- Description: Background: Breastfeeding is a common practice, but exclusive breastfeeding for the first six months is no longer a cultural norm in the majority of South African communities. Identification of facilitating and constraining factors which affect breastfeeding and exclusive breastfeeding practices is thus important. The promotion of exclusive breastfeeding is essential for improved infant health and development, especially if it takes into consideration the broader cultural and socio-economic aspects influencing these practices. This study follows up on an initial project conducted in Glenmore and Ndwayana, two rural communities in the Eastern Cape, South Africa. The current study aimed at working with community care workers who are associated with two community based organisations, who work within three communities, Glenmore, Ndwayana and Grahamstown. The study objectives were to identify the factors that influence the adoption of exclusive breastfeeding in the communities researched, to conduct workshops with the community workers on exclusive breastfeeding practices, as well as to develop and implement a facilitator’s manual for the promotion of exclusive breastfeeding. Method: Using the community based participatory research approach and the PEN-3 theoretical framework to guide the research process, individual semi-structured interviews were conducted with 14 community care workers to identify the factors that affect breastfeeding and exclusive breastfeeding. Through participatory involvement and a cyclical research process, a facilitator’s manual on breastfeeding was developed, which was used during the workshops in the training of community care workers on breastfeeding and exclusive breastfeeding practices. A pre and post intervention knowledge questionnaire was given to the community care workers to complete before and after the workshops. The facilitator’s manual was modified based on 14 months of consistent interaction with the community care workers, who provided feedback on improving the content as well as on how to enhance the cultural appropriateness of the facilitator’s manual during guided focus group discussions. Readability testing also guided further modification of the facilitator’s manual. Results:The major findings confirmed that exclusive breastfeeding for six months was no longer a common practice in these three communities. Factors affecting breastfeeding and exclusive breastfeeding were classified as perceptions (knowledge attitudes and beliefs), enablers (resources and facilities) and nurturers (people), in accordance with the PEN-3 model thematic categories. The knowledge questionnaire, semi-structured interview results, and data from the workshops showed that the community care workers were not sufficiently equipped with information on breastfeeding and exclusive breastfeeding. The facilitator’s manual development and modification was made possible by inputs from the community care workers and the community based organisation liaisons. A culturally appropriate, community specific facilitator’s manual for the promotion of breastfeeding and exclusive breastfeeding was produced. Conclusion: The factors affecting breastfeeding and exclusive breastfeeding were identified. These factors were useful in facilitating discussions on how to improve breastfeeding and exclusive breastfeeding practices in the communities researched. The facilitator’s manual and the workshops were useful in equipping community care workers with knowledge on breastfeeding and exclusive breastfeeding. The involvement of community based organisations will assist to ensure sustainability of breastfeeding promotion by community care workers by adopting the facilitator’s manual as part of their women and child development programmes.

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

- Description: Although a large body of international literature has advanced our understanding of river systems, a considerable amount of gaps exit in the knowledge of dryland systems. River systems reflect complex interactions between biophysical processes and patterns. Understanding how processes generate observed patterns and, in turn, how patterns influence processes is crucial to understanding river structure and function. It requires an interdisciplinary approach in both research and resulting applications. The aim of this thesis was to examine the relationship between valley confinement, fluvial style, valley floor morphology and vegetation in the semi-arid environment of the Baviaanskloof river catchment, South Africa. This interdisciplinary investigation used a mixed method approach that involved desktop analyses and field surveys to understand dynamics at multiple scales, from the whole catchment to local (site, reach and quadrat or sample plot) scales. The desktop analyses included historical rainfall patterns and climate extremes, aerial photograph time-series and remote sensing greenness indices, and the field surveys focussed on cross-valley landform profiles, groundwater depth levels, sediment size distribution and soil chemistry, and vegetation distribution patterns. Based on the integrative assessment of these techniques a framework was developed of the links between valley confinement, surface-groundwater interaction, hydrogeomorphic processes and landforms, vegetation and human activities. Study findings highlighted the fact that very strong links exist between these factors. In this semi-arid area water availability (groundwater and streamflow conditions) was the primary control on valley floor vegetation composition and patterning. One group of species was associated with the wetted channel reaches at confined and semi-confined valley settings, while the other was associated with dry bed channel reaches at unconfined valley settings. The analyses also indicated that the environmental variables which best explained the variation in vegetation at the differing geomorphic landforms were related to landform position (elevation and distance), sediment size (fine and coarse sand) and available phosphorus (i.e. human impacts). The different plants, in turn, also affected landforms through their influence on sediment erosion, transport and deposition. Specially, they build, maintained or modified geomorphic landforms at confined, semi-confined and unconfined valley settings across the valley floor. Valley confinement was a primary control influencing hydrogeomorphic processes and their associated landforms. Alluvial fans and terraces acted as critical additional controls at especially the unconfined valley setting. Implications for restoration efforts in the catchment included strategies that took cognisance of: active revegetation on floodplain surfaces related to former agricultural fields; channel switching associated with the highly dynamic and unpredictable nature of geomorphic features; unstable multi-thread braided channels in the unconfined valley setting; and the selection of representative monitoring sites.

The different plants, in turn, also affected landforms through their influence on sediment erosion, transport and deposition. Specially, they build, maintained or modified geomorphic landforms at confined, semi-confined and unconfined valley settings across the valley floor. Valley confinement was a primary control influencing hydrogeomorphic processes and their associated landforms. Alluvial fans and terraces acted as critical additional controls at especially the unconfined valley setting. Implications for restoration efforts in the catchment included strategies that took cognisance of: active revegetation on floodplain surfaces related to former agricultural fields; channel switching associated with the highly dynamic and unpredictable nature of geomorphic features; unstable multi-thread braided channels in the unconfined valley setting; and the selection of representative monitoring sites.
