- Description: Against the backdrop of debates on feminism and neo– liberalism, this thesis presents a critical analysis of Rand Merchant Bank’s (RMB) Athena programme in South Africa – an award– winning programme run by women, which aims to develop women as senior managers – and of the type of feminism it represents, using a Marxist feminist theoretical framework. Rand Merchant Bank’s is one of the largest investment banks in Africa, part of the giant First Rand Group (FRG) alongside First National Bank (FNB) group. The thesis, based on a detailed case study using qualitative methods, argues that Athena is a very much product of its time: it advances the argument that if more women were in position of power, women in general would be free, and it views the problem of women’s oppression with an individualist lens, which focuses on attitudes and confidence. Athena, like many initiatives of the neo– liberal era, such as Sandberg’s Lean– In philosophy and the Nike Foundation’s ‘Girl Effect’ promote individual understanding and emancipation of women, which sees emancipation in terms of creating a neo– liberal subject that operates more effectively within a capitalist framework, sees capitalism as the solution – rather than the cause – of women’s unequal circumstance and ignores structural issues like class. In effect, Athena argues that the free market and big corporations are neutral tools that can answer the question of women equality, if only women had the correct attitudes, and so long as corporate hierarchies and profits are accepted as fair, and women are seen as an untapped resource that can be used in a ‘smart economics.’ What all these initiatives have in common is shifting the burden and responsibility to women without proper interrogation of the systems that perpetuate inequalities, and a trickle– down theory, according to which more women capitalists and more women in the ruling class will empower the women in the working class.

- Description: The aim of this study was to uncover preschool caregivers’ and parents’ views about preschool education as a preschool readiness programme in the Queenstown education district. The research study addressed the following specific objectives, to determine: the caregivers’ and parents’ understanding of school readiness nature of preschool education; the extent to which the caregivers’ practices can make children ready for formal schooling; the parents’ assessment of the preschool centres as places that make children ready for formal schooling; caregivers’ and parents’ views on the challenges facing preschool centres against making children ready for formal schooling; and lastly, the possible solutions to the challenges facing preschool centres. In the present study, both qualitative and quantitative data were collected. Quantitative data were gathered through questionnaires from 40 preschool caregivers at preschools and 40 parents of the children in those preschools that were chosen by the caregivers on the basis of parents who are highly committed in the education of their children. The qualitative data were gathered through focus group discussions with 2 focus groups located in the Queenstown Education district. Twelve participants were interviewed, and these comprised 6 caregivers that formed the focus group discussion 1 and 6 parents that formed the focus group discussion 2, using the interview schedules as guides. Purposive sampling to select the participants was used. Triangulation design was used to gather both quantitative and qualitative data at the same time and to integrate the two forms of data in order to have a better understanding of the research objectives. The research findings indicated that the most frequently reported issues by the participants were the problems with some caregivers who had limited knowledge to make children ready for formal schooling. Some of the parents and caregivers do not understand the importance of the domains of development in making children fully ready for formal schooling. There is still lack of parental involvement in those centres; no effective communication between parents and staff; caregivers are not aware of the policies that govern the preschools; poverty and unemployment are factors that inhibit the right of young children to education; no proper resources in preschools and the unregistered preschools also still need to be helped by coordinated efforts from communities and the government bodies. It was concluded that the quality of early childhood development(ECD) programmes in Queenstown preschools was still compromised. The study recommended extensive investment in infrastructure and learning and teaching support materials is necessary; there should be sufficient staffing with ECD expertise; programmes should be designed in order to educate and encourage parents to actively involve themselves with preschool activities.

- Description: The late Nkosi Johnson was one of the youngest Human Immunodeficiency Virus (HIV) activists in South Africa and the longest known HIV positive child who survived without antiretroviral drugs (Nkosi Haven, 2016). His life story was characterized by his brave fight against the acumen that environs people living with HIV/AIDS and especially during a time when there were many misconceptions surrounding the condition. During the twelve years that he lived, Nkosi had the opportunity to make a difference, both nationally and internationally. The support he received allowed him to internalize many positive attributes such as bravery, courage, endurance and love which eventually made him a positive role model and activist for his cause. This study made use of Erikson’s Psychosocial Development Theory to highlight the short-lived but influential life of Nkosi Johnson. The study is a single case study and is qualitative in nature. Biographies, published information, and contact made with his adoptive mother, Gail Johnson, were all constituents gathered as data used for the study. The collected data was analysed using Miles and Huberman (1994) steps of data reduction, data display, as well as conclusion drawing and verification. Moreover, the data was organised and integrated in a conceptual matrix which guided the analysis, presentation and discussion of the research findings. The findings of the study suggested that although Nkosi Johnson experienced difficulties in his process of psychosocial development he was able to achieve Erikson’s seventh stage ‘Generativity versus Stagnation’, even though he lived a short life. These findings support the notion that continued research into the applicability of the sequential age order of developmental theories is needed.

- Description: Network Telescopes, Internet backbone sampling, IDS and other forms of network-sourced Threat Intelligence provide researchers with insight into the methods and intent of remote entities by capturing network traffic and analysing the resulting data. This analysis and determination of intent is made difficult by the large amounts of potentially malicious traffic, coupled with limited amount of knowledge that can be attributed to the source of the incoming data, as the source is known only by its IP address. Due to the lack of commonly available tooling, many researchers start this analysis from the beginning and so repeat and re-iterate previous research as the bulk of their work. As a result new insight into methods and approaches of analysis is gained at a high cost. Our research approaches this problem by using additional knowledge about the source IP address such as open ports, reverse and forward DNS, BGP routing tables and more, to enhance the researcher's ability to understand the traffic source. The research is a BigData experiment, where large (hundreds of GB) datasets are merged with a two month section of Network Telescope data using a set of Python scripts. The result are written to a Google BigQuery database table. Analysis of the network data is greatly simplified, with questions about the nature of the source, such as its device class (home routing device or server), potential vulnerabilities (open telnet ports or databases) and location becoming relatively easy to answer. Using this approach, researchers can focus on the questions that need answering and efficiently address them. This research could be taken further by using additional data sources such as Geo-location, WHOIS lookups, Threat Intelligence feeds and many others. Other potential areas of research include real-time categorisation of incoming packets, in order to better inform alerting and reporting systems' configuration. In conclusion, categorising Network Telescope data in this way provides insight into the intent of the (apparent) originator and as such is a valuable tool for those seeking to understand the purpose and intent of arriving packets. In particular, the ability to remove packets categorised as non-malicious (e.g. those in the Research category) from the data eliminates a known source of `noise' from the data. This allows the researcher to focus their efforts in a more productive manner.

Catholic and charismatic: identity construction in a catholic charismatic movement in Nigeria

- Description: The Catholic Charismatic Renewal is a movement within the Catholic Church that blends and synthesizes elements of Catholicism and Pentecostalism. The movement straddles these two religious traditions within Christianity. Besides its incorporation of elements of Catholicism and Pentecostalism, the movement also has as its objective, the revitalizing and renewal of the Catholic Church through the power of the Holy Spirit. These fundamental orientations of the Catholic Charismatic Renewal distinguish it from other Catholic movements, bestowing on it its unique identity. Although different from other Catholic movements, the movement and its members lay claim to a Catholic identity and seek to assert its legitimacy within the Catholic Church. Existing literature has provided useful insights into the question of identity within the Catholic Charismatic Renewal. However, the question of identity construction within the movement has not been adequately and comprehensively addressed in academic literature. This is especially the case in the African context. This leaves therefore a gap in our knowledge of how the movement and its members construct their catholic and charismatic identities. This study sets out to explore how the movement and its members construct their identity in relation to the Holy Spirit, the institutional Catholic Church and other Catholics, as well as in the context of the movement’s ritual music. Identity construction in the Catholic Charismatic Renewal is seen as key to making meaning of the movement and its place within Catholicism. The study adopted a qualitative research and ethnographic approach in which empirical data was collected in the context of fieldwork through informal, semi-structured and focus group interviews as well as participant observation during the activities of a Catholic Charismatic prayer group in Minna, Nigeria. Theoretical perspectives drawn from identity, hermeneutics and anthropology of extraordinary experience were used as analytical lens in the study. The study revealed that identity within the Catholic Charismatic Renewal was constructed principally in relation to the Holy Spirit. A spiritual experience or encounter was central in such identity construction, and the subjective and intersubjective identity of the members revolved around the two key concepts of ‘spirit-centred identity’ and ‘empowerment’. The study indicated that the members of the movement constructed their identity in ways that demonstrated their loyalty to the Church and their status as an officially recognised Catholic movement. In addition, their identity was also constructed in relation to the functions that they perceived themselves to perform within the Catholic Church. Although the members of the movement considered their charismatic and catholic identities to be compatible, they understood themselves to be different from other Catholics. The study also showed that while music was considered to be important within the movement, the context and content of its ritual music were overwhelmingly Pentecostal, and music that projected a catholic identity was relegated to the background and given expression mainly in the realm of individual religious practice. The study suggests that identity construction within the Catholic Charismatic Renewal is multiple, ongoing, flexible, and sometimes contradictory and paradoxical. Through its identity construction, the members of the movement demonstrate the heterogeneity of the Catholic space and seek to extend the boundaries of Catholicism.

- Description: The Construction Industry (CI) is recognised as a formidable sector that has the potential of facilitating the growth and development of a nation’s economy by providing the necessary infrastructure that is required to spur the growth of other industries. In many countries, such as Malawi, the city councils (CCs) also influence the implementation and management of such infrastructure as mandated by the Malawi Local Government Act (1998). Successful projects should be implemented in such a manner that completion of the projects is within the golden triangle of cost, time and quality. This implies that projects are completed within the planned budget, stipulated time and specified quality. City Councils in Malawi, however, face various challenges in their implementation of infrastructure projects leading to delayed project completion, resulting in extended project implementation periods. This study aimed at finding the causes of road projects construction delays in Blantyre City Council, (BCC) which is one of the four CCs in Malawi, the second largest and the commercial capital. The study followed a qualitative research method using a case study approach. This study combined in-depth, face-to-face interviews of identified stakeholders with general routine work observations and project document gathering to collect the primary data while secondary data was obtained from books, research journal articles, government documents, unpublished theses, some international organisation reports, general internet information and other academic related sources of relevant information. The participants included council representatives (council service committee chairperson, secretariat management staff), contractors’ representatives and consultants’ representatives. The participants were chosen using a non-probability sampling method of purposive and snowball selection, targeting their involvement in the previous and/or the current project implementation cycles. The study also involved visiting some of the ongoing and completed projects and collecting project photographs. The findings from the case study revealed challenges the council faced due to a shortage of engineers in conducting detailed proposed projects surveys resulting in incomplete project scope definition (detailed designs) on some projects, before the procurement of contractors as the major cause of project construction delays. Other factors that were identified were: service providers delaying the removal of existing public utility infrastructure from project sites, inclement weather and the client delays in issuing instructions to the contractors during the implementation of the projects. Another factor was the shortage of construction equipment and construction materials by some contractors. Based on the research findings, the main recommendation is to increase the number of technical employees, especially engineers and other key technical staff such as quantity surveyors by improving the employees’ conditions of service. Improving the service conditions will attract and retain the right quality and quantity of technical employees to undertake the management of the construction projects. Alternatively, all positions for professionals who are deemed as scarce or hard to maintain could be placed on a contract basis, renewable after a period of two to three years. This would be able to attract those professionals who are ready to offer their expertise for a certain period but may not necessarily want to work until the government mandatory retirement. This will be in addition to the engagement of external project consultants to assist in project management, which the council started implementing in 2017. As for the delay in the removal of utility services infrastructure on proposed project sites, the client needs to commence with the process early in the planning and procurement process before handing over the project sites to the contractors. General contractor delay causes can be minimised by raising the selection criteria of contractors to flush out as well as black-listing incompetent contractors.

- Description: The 2014 national general elections were characterised by a cloud of scandal hanging over the ANC, and the ANC president Jacob Zuma. The biggest and darkest cloud was the Nkandla scandal. Owing to a reported R246 million spent by the state to refurbish his private home, the president stood accused of wasteful expenditure and financial irregularity. In a country reeling from the continued effects of apartheid, which include high unemployment and poverty, the scandal was a bombshell. According to a vocal and often adversarial mainstream media sphere, the ANC went into those elections with an albatross around its neck. The dominant thought was that the ruling party would suffer a heavy loss of votes. This outcome did not materialise. The ANC lost a marginal share of its previous vote. Mainstream media and civil society were confounded. What had happened? Why had poor black South Africans continued to vote for a party that was obviously in breach of the constitutional order? Against the mismatch between what was predicted or purported and the outcome, this study investigates how young people in the township of Joza, Grahamstown, interpreted one of the biggest political scandals in South Africa’s fledgling democracy. Using a combination of subaltern studies, counter public sphere and audience study, the research looks into the interpretation of a mainstream media scandal that was supposed to diminish the chances of the ANC retaining power, but, instead, barely dented its majority. Through a combination of interviews and participant observation, the study found that young people in the township of Joza demonstrated that they chose to ignore the messages about the corruption of the ANC. The data suggests that they did so, not because of overt racial solidarity, but due to the fact that in a context of high inequality, and continued limitations on economic emancipation, the party shone brightly as a vehicle for economic development. Overall, the study argues that the seemingly dubious undertaking to continue with the ANC is a calculated decision that makes sense when viewed within a given socio-economic context.

- Description: The 2014 national general elections were characterised by a cloud of scandal hanging over the ANC, and the ANC president Jacob Zuma. The biggest and darkest cloud was the Nkandla scandal. Owing to a reported R246 million spent by the state to refurbish his private home, the president stood accused of wasteful expenditure and financial irregularity. In a country reeling from the continued effects of apartheid, which include high unemployment and poverty, the scandal was a bombshell. According to a vocal and often adversarial mainstream media sphere, the ANC went into those elections with an albatross around its neck. The dominant thought was that the ruling party would suffer a heavy loss of votes. This outcome did not materialise. The ANC lost a marginal share of its previous vote. Mainstream media and civil society were confounded. What had happened? Why had poor black South Africans continued to vote for a party that was obviously in breach of the constitutional order? Against the mismatch between what was predicted or purported and the outcome, this study investigates how young people in the township of Joza, Grahamstown, interpreted one of the biggest political scandals in South Africa’s fledgling democracy. Using a combination of subaltern studies, counter public sphere and audience study, the research looks into the interpretation of a mainstream media scandal that was supposed to diminish the chances of the ANC retaining power, but, instead, barely dented its majority.

- Description: Animals sculpt landforms by physically altering the substrate. The field of zoogeomorphology has developed to explicitly consider the role of animals as geomorphic agents. Many digging and burrowing animals are then considered zoogeomorphic agents. While the significance of soil disturbing species is well established, geomorphic impacts are rarely quantified for rock transporting species. Chacma baboons (Papio ursinus, hereafter baboon), a widespread and abundant primate, have the potential to act as a zoogeomorphic agent through their purposeful rock displacement while foraging. With this study I assessed the role of baboons as rock rolling agents by demonstrating that baboons roll rocks to search for and feed on organisms beneath, quantifying the extent of this process, and establishing the preferences of baboons for rock features. Observations from a troop of wild baboons showed that rock rolling is an important component of the daily foraging routine of baboons, and confirmed that baboons roll rocks to feed on the organisms beneath. Baboon rock movement was extensive, with potentially tons of rock material moved across many hectares over one year in some habitats. The distance of this rock movement was influenced by a combination of rock mass, rock shape and the slope of the landscape. Baboons showed clear preferences for the rocks they rolled in terms of shape and size, with rock size being an important driver of baboon rock rolling. With this study I show that the chacma baboon is an important rock moving species, with the potential to impact a range of ecological and geological processes. As such, baboons may serve as a keystone species as they are the only species in this environment to intentionally move rocks in this way. However, because baboons are considered pests and are widely persecuted, their role in zoogeomorphic processes are vulnerable to being lost.

- Description: The study aimed to investigate the challenges that older grandparents face in caring for their grandchildren in Mdlankomo Location, Libode, Eastern Cape. The study intended to achieve three (3) objectives: (i) to establish factors that make caregiving of children by their grandparents challenging, (ii) to establish resources that grandparents need to care for their grandchildren and (iii) to establish the availability of resources required by the grandparents to care for their grandchildren and its possible gaps. The study utilized qualitative research approach, and date collection methods used were in-depth interviews, focus group discussion and key informant method. The number of participants was 34 in total consisting of 23 grandparents and 11 key informants. The findings of the study showed that death of children’s own parents; cultural expectations, youth unemployment, abdication of parental responsibilities, youth unemployment, and carelessness of biological parents were the major reasons for grandparents to care for their grandchildren. The study findings also revealed that grandparents in this caregiving experience both benefits and barriers. The findings further revealed that there are gaps in welfare services, medical services and education. Therefore, the researcher recommended that, those in power should be interested, eager and inquisitive enough about certain aspects that need attention in caregiving of children by their grandparents.

- Description: The purpose of this study was to investigate the extent to which the Beacon Bay Community Police Forum in the East London area has implemented the Community Police Forum (CPF) uniform constitution. The main research question of this study was: To what extent has the Beacon Bay Community Police Forum in the East London area implemented the uniform Community Police Forum (CPF) constitution? The theoretical framework that guided this study was the broken windows theory. The literature review looked into the following: existing knowledge based on the assessment of the implementation of the uniform CPF constitution by the Beacon Bay Community Police Forum, the regulatory framework and an overview of the role and functions of the community police forum (CPF) in South Africa, lack of awareness and representativeness as challenges to community police forums effectiveness, inadequate resources in the implementation of an effective community policing forum, lack of trust between the police and the community and the issue of corruption as challenges in the implementation of CPF. The qualitative research method was used in this study. The case study design was also used. The researcher used the purposive sampling technique to select six community members and four community executives of the Beacon Bay CPF in the East London area. Face-to-face in-depth individual interviews were used to gather in-depth data. The manual method of analysis was used. The researcher analysed the data by capturing the patterns and direct words of the participants who were interviewed through note taking. Themes were drawn from the responses of the participants and analysed. Some of the findings were that: Community members did not know exactly when the CPF was implemented, the CPF was not effective, community members did not attend CPF meetings and had negative attitudes towards CPF, the police worked better with the rich people rather than the poor ones and there were some influences of politics in the CPF. In addition, the resources lacking at the CPF were: SAPS staff, shortage of police stations and insufficient vehicles at the police stations. Furthermore, some police worked hand-iniv hand with the criminals and the repercussions of poor trust between the community and the police included: community members taking the law into their own hands, poor handling of criminal cases, and escalation of crime in the community. Some community members noted the positive effect that the implementation of the community police forum had as they could now engage the police directly on matters relating to crime and how they think such challenges can be addressed. The researcher made some recommendations towards an effective implementation of the Community Police Forum in Beacon Bay in East London.

Challenges of subsistence farming in South Africa: a case study of Emjkweni village in Eastern Cape Province

- Description: Subsistence agriculture plays an important role in the livelihood of Africa’s rural population. Yet in many countries like South Africa, rather than seeing an upward projection of food production with an almost natural shift towards commercialising household production of food, the state of rural agriculture continues to go into decline. Since the advent of South Africa’s new dawn of democracy in 1994, agriculture has been the priority of government for the advancement of subsistence economy and rural development in rural communities. But progress in making a vibrant sustainable economy out of subsistence farming has remained stymied. At a time when there is a need to significantly increase the productivity of subsistence/smallholder agriculture and ensure long-term food security, rural subsistence farmers in the former bread basket of the Eastern Cape Province, have abandoned crop production. Characteristic of contemporary Eastern Cape’s rural landscape is the sight of large tracts of farm land lying uncultivated. Amidst a raging debate in South Africa on land the merits of the debate remain silent in the face of visibly idle crop land. This study has attempted to make a small incision into a growing body of knowledge on land reform with a view to and laying bare current challenges that keep rural folk out of the field, notwithstanding availability of land. Adopting multi-level research techniques, a purposive sample of 83 village respondents in eMjikweni was selected. Through a combination of face-to-face interviews using an open-ended interview instrument; focus group discussions and case studies, information was extracted from the sample to understand the current challenges of subsistence farming that make for poor household crop production, intensified dependence on social grants for income and growing food insecurity. Despite a conducive policy environment, the study findings suggest that as long as political will is absent, the formula for agrarian reform will remain incorrect, further entrenching rural poverty. As an exercise in social enquiry, the study employed a combination of quantitative and qualitative data analysis methods, while being careful to note how methodology impacts on the ability of respondents to narrate their lived experience, which, carefully crafted, can be valuable catalysts to a more bottom-up approach to rural development, sustainable agriculture and enhanced food security in the Eastern Cape. The merit of this study in making the said incision into a growing body of information on land reform is that it provides a glimpse into the life of a rural subsistence farmer. With the launch of the Presidential Panel Report on Land Reform (2019) a few days ago, the voice and experience of those who bear the brunt of land reform becomes critical. They are a people facing enormous challenges to restoring subsistence agriculture as a vibrant contributor to food security at household level and to reduced dependency on the state for its livelihood. They are a people who once created the “bread basket” of the Eastern Cape Province with a vibrant agricultural economy. They are a people who raise children to form part of the significant statistics of migrants to the economic hubs of Gauteng Province in particular in search of employment. They are a people who contribute significantly to the growing numbers of people dependent on the state for social grants. They are a people central to solving land reform for a better South Africa. It is based on their stories that this study’s findings argue for the revitalisation of the subsistence economies of rural communities which recognises the deeply entrenched socio-economic and geo-spatial transformations over time that make it quite complex to return to a past utopia. It is the premise of this thesis that the smallholder and subsistence agricultural sector has the potential to create job opportunities and promote local economic development in rural communities, which in turn would mitigate the triple challenge of poverty, unemployment and inequality facing South African society.

- Description: According to National Department of Health (NDOH National :2015), antenatal care is free in South Africa’s public health system and nearly all pregnant women and girls attend an antenatal clinic at least once during their pregnancy. However, most pregnant women do not access antenatal care until the later stage of pregnancy. Such delays have been linked to nearly a quarter of avoidable maternal deaths in South Africa. According to World Health Organisation (WHO, 2016; 11), maternal mortality and morbidity are some of the most important global health issues facing the world today. Worldwide, approximately 1000 women die each day from pregnancy and childbirth related causes (WHO, 2016; 11). In addition, 99% of these maternal deaths occur in the developing world, with sub-Saharan Africa accounting for over half of these deaths. The international community has committed to improving maternal health by 2015 with Millennium Development Goal (MDG) number five, which aimed to reduce maternal mortality by three quarters and reach universal access to reproductive health care (www.worldbank.org/mdgs/). Even with this commitment, many countries like South Africa have failed to implement effective programs to reduce maternal mortality and morbidity, and women around the world continue to die and suffer from the complications of pregnancy and childbirth. According to NDOH (2015; 2), women who suspect that they might be pregnant should schedule a booking and visit to their clinic and begin antenatal care as soon as possible. These visits include a physical examination, which includes blood pressure checks, weight checks, providing a urine sample, testing for sexually transmitted infections and checking for tuberculosis. Depending on the stage of the pregnancy, healthcare providers may also do blood tests and examination, which includes an ultrasound. The purpose of the study was to to investigate the challenges of Primigravida’s in accessing antenatal care early and regularly in Buffalo City Metropolitan (BCM) and to assist in formulating recommendations for improving factors that are perceived as obstacles to the utilisation of antenatal care services in the BCM District. vii The study was conducted in five facilities at BCM (Dimbaza Community Health Centre, Empilweni Gompo Clinic, Moore Street Clinic, Central Clinic and Notyatyambo Clinic). BCM is one of the seven districts of Eastern Cape Province of South Africa. The seat of BCM is East London. The data was collected using cross-sectional, self-administered questionnaires that were conducted in selected health facilities of Buffalo City Metropolitan. In this study, the population consisted of primigravida’s between the ages of 18-35 who start clinic attendance in the second trimester of pregnancy at five facilities, Buffalo City Metropolitan. Findings: The biggest challenges, as expressed by the participants, were lack of money, unsuitable clinic times, work commitments, delays at clinic and family control. Most of the participants had good experiences of antenatal care. The timing of antenatal clinic attendance is not influenced by age, education, residential zone, employment status and proximity of clinic

- Description: Literature review indicates that world over, fraction operations in primary school are challenging not only for learners but also for teachers and South Africa is not an exception. There have been studies on challenges of fraction operations, but could not locate any study at a Grade 6 level in East London education district. The purpose of this study was to assess the specific strengths and challenges in the learning and teaching of fraction operations in Grade 6 in one of the schools in this district. The research paradigm for this study was post-positivism which adopted a mixed methods approach, utilising both quantitative and qualitative methods. The population consisted of three teachers and 98 Grade 6 learners in one primary school in East London. The learners were under 18 years and in order to comply with South African ethical regulations involving humans, a letter was sent out to all 98 Grade 6 learners’ parents requesting their consent. Only 59 learners brought back the consent letters signed by a parent or legal guardian and hence, the sample consisted of 59 Grade 6 learners. There were two instruments: a survey questionnaire with 15 items for learners and two interview schedules, one for teachers and another for learners. The time to complete the questionnaire was 45 minutes and the time to complete the interviews was less than 20 minutes for learners and 40 minutes for teachers. As part of a pilot study, the questionnaire was given to six learners in 2017 cohort. Also, the questionnaire was given two colleagues teaching Grade 6 from two different schools. Furthermore, two learners from the 2017 cohort and two colleagues from two different schools were interviewed, respectively, to check the validity of the learners’ and teachers’ interview schedules. Based on the feedback, the instruments were modified for use in 2018. The learners were given the questionnaire to answer first before 10 were selected for interviews. Three teachers, one each from Grades 5, 6 and 7 were interviewed. The quantitative data were analysed to lead to a descriptive data presentation. The qualitative data were analysed thematically. It was revealed that there were similarities and differences in the manner in which teachers teach and the challenges they identified. There were similarities and differences among the responses from the learners. They found certain fraction operations challenging and their strengths were similar as well. The common outline of the learners’ strengths were being able to do like-fractions while, their challenges were on doing unlike-fractions. The teachers too concurred with the learners’ views. The learners got confused because they did not understand fractions as part of a whole. The teachers indicated knowledge of more than one teaching method. The teachers also pointed out how times tables is an essential part of being able to do operations of fractions. This study could be beneficial for teachers, learners, parents and curriculum developers. The curriculum developers need to revisit the time frame, the transition between the grades, and how often the concept of fractions appears throughout every term.

The purpose of this study was to assess the specific strengths and challenges in the learning and teaching of fraction operations in Grade 6 in one of the schools in this district. The research paradigm for this study was post-positivism which adopted a mixed methods approach, utilising both quantitative and qualitative methods. The population consisted of three teachers and 98 Grade 6 learners in one primary school in East London. The learners were under 18 years and in order to comply with South African ethical regulations involving humans, a letter was sent out to all 98 Grade 6 learners’ parents requesting their consent. Only 59 learners brought back the consent letters signed by a parent or legal guardian and hence, the sample consisted of 59 Grade 6 learners. There were two instruments: a survey questionnaire with 15 items for learners and two interview schedules, one for teachers and another for learners. The time to complete the questionnaire was 45 minutes and the time to complete the interviews was less than 20 minutes for learners and 40 minutes for teachers. As part of a pilot study, the questionnaire was given to six learners in 2017 cohort. Also, the questionnaire was given two colleagues teaching Grade 6 from two different schools. Furthermore, two learners from the 2017 cohort and two colleagues from two different schools were interviewed, respectively, to check the validity of the learners’ and teachers’ interview schedules. Based on the feedback, the instruments were modified for use in 2018. The learners were given the questionnaire to answer first before 10 were selected for interviews. Three teachers, one each from Grades 5, 6 and 7 were interviewed. The quantitative data were analysed to lead to a descriptive data presentation. The qualitative data were analysed thematically. It was revealed that there were similarities and differences in the manner in which teachers teach and the challenges they identified. There were similarities and differences among the responses from the learners. They found certain fraction operations challenging and their strengths were similar as well. The common outline of the learners’ strengths were being able to do like-fractions while, their challenges were on doing unlike-fractions. The teachers too concurred with the learners’ views. The learners got confused because they did not understand fractions as part of a whole. The teachers indicated knowledge of more than one teaching method. The teachers also pointed out how times tables is an essential part of being able to do operations of fractions. This study could be beneficial for teachers, learners, parents and curriculum developers. The curriculum developers need to revisit the time frame, the transition between the grades, and how often the concept of fractions appears throughout every term.

- Description: A forge allows the creation of both utilitarian craftwork and artworks. It is difficult to find blacksmiths who are willing to pass on their knowledge, particularly in South Africa where the art of blacksmithing is practised by a small number of individuals who rely on their labour for an income. This dissertation documents the building of a forge and what is needed to practise the art of blacksmithing, sourcing of the materials, and the application of blacksmithing to make pleasing artefacts. The document includes the processes of forge tool-making, providing an avenue for future students to fabricate tools and use the processes for art-making as well as list of suppliers and list of blacksmiths in South Africa.

- Description: Research attests that beliefs in water spirits are an integral part of cultures of many indigenous communities across the globe. These water spirits play significant political, religious and socio-economic roles for the people concerned. However, the functions of water spirits are not constant, but change over time, especially when the people believing in water spirits undergo drastic socio- economic processes of change. It is in this context that this thesis traces the cultural significance over time, of the Nyaminyami water spirit, among some BaTonga people, living in the immediate vicinity of the Kariba gorge area, in north-western Zimbabwe. While previous studies document the existence of beliefs in Nyaminyami, none of these has systematically traced the historical significance of Nyaminyami, in terms of changes and continuities over time. Thus, this thesis makes a valuable contribution to knowledge with regards to the history and religion of the BaTonga people. The thesis argues that Nyaminyami‘s cultural significance or functions evolved over time, due to numerous socio- economic and political processes of change. The major changes that significantly influenced the practices relating to Nyaminyami include colonialism, Kariba dam construction and resettlement, the migration after resettlement in the 1960s and 1970s, the independence of Zimbabwe, and the alienation of the Kariba waterscape from the BaTonga. To be able to arrive at specific findings and conclusions, the thesis is underpinned by theories about resettlement, approaches to water divinities, and theories of religion and social change. The thesis has five ethnographic chapters that focus on specific time periods, illustrating the major socio- economic changes of each epoch, and showing how these changes impacted upon practices and beliefs relating to Nyaminyami. The thesis also documents how Nyaminyami beliefs are variedly distributed along different social variables that include gender, age, income and geographical location. In order to achieve the findings presented, the thesis utilized ethnographic evidence obtained from semi- structured interviews, participant observation, anthropology of extraordinary experience, document review and archival research.

- Description: Many rural areas are experiencing rapid social-ecological changes, impacting livelihoods and creating less certain futures. Despite several decades of research on the use of locally collected environmental resources there have been few repeat studies, especially in South and Southern Africa, to consider how households may be altering such use alongside other changes. This paper explores changes in the use of environmental resources by communities in the Kat River Valley, South Africa over a fifteen-year period, between 2000 and 2015, using a repeat survey, key informant interviews and other data from a larger study relating to social-ecological change. The proportion of households collecting different environmental resources was similar between the two periods. However, the mean quantities used per household had declined for several resources . Consequently, the monetary contribution or worth of these to livelihoods also declined, except for fuelwood and river sand. These changes can be related to, amongst others, transformations in both the local landscape and socio-economic environment, such as increases in state social welfare, a decline in agricultural production, woody plant encroachment, generational preferences, and the expansion of supermarket retailers. Understanding such trends is important for considering the sustainable management of landscapes and livelihoods into the future.

Changing gender roles: challenges and strategies of female headship in Motherwell

- Description: For decades, research has examined men’s perceptions of the changing gender roles, highlighting the masculinity crisis and challenges men encounter due to the decreasing male provider role. Yet, studies have not explored women’s perceptions about these changing roles, which have consequentially enabled them to become female-headed households (FHHs). Part of the problem is that in theory, FHHs have indeed been classified as the poorest of the poor. Nevertheless in practice, governments have neglected efforts to support this group. In South Africa, research on challenges of FHHs is quantitative and portrays an overgeneralised image of poverty in FHHs. This study set out to develop a better understanding of how women make sense of the changing roles, in an attempt to investigate the processes through which women assume their headship status and to examine their challenges and strategies as FHHs. Using a qualitative research design in the form of a case study with a phenomenological study orientation, the study identified 40 female participants and the data was collected using in-depth interviews. Data was analysed through inductive thematic analysis. Findings indicated that female headship occurs through an identifiable process and most women were never married, divorced, separated or widowed. Thus, single motherhood is by choice, because it is a choice for independence. The significant obstacle hindering social progress is that women support the changing gender roles, while at the same time utilising linguistic repertoires to hold on to traditional gender role beliefs that reinforce patriarchy. Their also challenges manifested in a similar behavioral fashion, suggesting the intergenerational transmission of poverty. Poor education, sex for jobs, feminisation of labour, teenage pregnancies, burden of care, dependency burden, discrimination, absence of fathers and inability to balance work and family, are challenges that put FHHs under a sustained attack. These findings indicate that despite being poor, women do not view themselves as victims of poverty. They exercise urgency through forging social capital, salaries and child support grants. However, women are stuck in a poverty trap because their relations of exchange are limited to those women who are equally poor.

- Description: The rapid advancements of COTS microprocessors compared to radiation hardened microprocessors has attracted the interest of system designers within the aerospace sector. COTS microprocessors offer higher performance with lower energy requirements, both of which are desired characteristics for microprocessors used in spacecraft. COTS microprocessors, however, are much more susceptible to radiation damage therefore their SEE and TID responses needs to be evaluated before they can be incorporated into spacecraft. This thesis presents the process followed to evaluate said characteristics of a COTS Intel Atom E3815 microprocessor mounted on a DE3815TYBE single board PC. Evaluation of the SEE response was carried out at NRF iThemba Labs in Cape Town, South Africa where the device was irradiated by a proton beam at 55.58 MeV and with varying beam currents. The device showed a higher sensitivity to functional interrupts when running with the onboard cache on compared to when running with the cache off, as would be expected. The cross-sections, respectively, are: 4.5𝑥 10−10 𝑐𝑚2 and 2.8 𝑥 10−10 𝑐𝑚2. TID testing on the other hand was carried out at the irradiation chamber of FruitFly Africa in Stellenbosch, South Africa. The test device was irradiated by gamma radiation from a Cobalt-60 source at a dose rate of 9.7kRad/h and to a total dose of 67.25kRad. Noticeable TID degradation, in the form of leakage currents, was observed once a total dose of about 20kRad was absorbed. The device then completely failed once a total dose of approximately 32kRad was absorbed. These results suggest that the E3815 microprocessor would not be suitable for long term missions that require higher TID survivability. The processor could however be considered for short term missions launched into polar or high incline orbits where the dose rate is relatively low, and the mission is capable of tolerating functional interrupts.

- Description: Thiazoles have shown a broad range of biological activities and are found in many potent biologically active molecules such as Sulfathiazol (antimicrobial drug), Ritonavir (antiretroviral drug), Abafungin (antifungal drug), and Tiazofurin (antineoplastic drug) [1]. They have exhibited some degree of plant growth regulatory and antifungal activities [2], whilst some thiazoles have shown anti-infective [3] as well as antibacterial activities [4]. The regio-controlled synthesis of 2,5-disubstituted and 2,4,5-trisubstituted thiazoles from ethyl-2-bromo-5-chloro-4-thiazolecarboxylates using sequential palladium-catalyzed coupling reactions has been reported [5]. An efficient general method for the preparation of 2,4-di- and trisubsituted thiazoles is via P–TsOH. H2O-Catalyzed cyclization of trisubstituted propargylic alcohols with thioamides has been accomplished with moderate to excellent product yields under mild and standard conditions [6]. In the presence of triethylamine, (Z)-(2-acetoxyl-1-alkenyl) phenyl-λ3 iodanes reacts with thioureas or thioamides in methanol to afford 2,4- disubstituted thiazoles in good yields. The reaction is thought to proceed by the generation of highly reactive α-λ3 iodanyl ketones through ester exchange of the β-acetoxy group with liberation of methyl acetate, followed by nucleophilic substitutions with thioureas or thioamides [7].
