  • Description: This study set out to investigate the structuring, recontextualisation and circulation of waste management knowledge in the South African environmental Expanded Public Works Programme (EPWP) Waste Management Projects. In this thesis these projects also referred to as the Working on Waste (WoW) programme or focus area within the Environmental Protection and Infrastructure Programme (EPIP) hosted by the National Department of Environmental Affairs. Expanded Public Work Programmes are a strategy used by governments to address unemployment and in South Africa; the programmes also seek to address a need for skills development. In this study, the focus is on EPWP waste management knowledge, training programmes and activities only. With waste management knowledge as the core interest, the focus of the investigation was on knowledge circulation of waste management via informal (participation in the project) and formal training of workers at Level 2 National Qualifications Framework (NQF). The study started by firstly investigating what waste management knowledge is produced in the Field of Production via scientific research and policy. It then studied how this waste management knowledge is recontextualised into qualifications and skills programmes designed in the official recontextualising field and learning materials and training programmes designed and offered in the professional recontextualising field. The study also focused on the knowledge of workers and their experience of training in the EPWP workplaces, with an emphasis on rural workplaces. This is where the Department of Environmental Affairs (DEA) is placing emphasis on training for job creation, empowerment and skills development, and it is also where a number of EPWP Working on Waste programmes are being implemented. The aim was also to develop an understanding of how knowledge circulates amongst learners in training sessions and in workplaces. To do this, I drew on Bernstein’s theory of the pedagogical device which provides theoretical lenses and a language of description to explain how knowledge is recontextualised from the field of production to the field of reproduction. To investigate the structuring of this knowledge by official and pedagogical recontextualisers, I drew on the work of Maton, who offers a Legitimation Code Theory to explain the principles structuring knowledge, of which I used specialisation and semantics (two of his suite of knowledge structuring principles) for analysis. The questions that guided the study throughout were: 1. What is the structure of legitimate knowledge and knowers in waste management? 2. What are the underlying principles underpinning knowledge and knowers in waste management? 3. How is the knowledge recontextualised in waste management training qualifications, documents and manuals for worker training at NQF Level 2? 4. How is the knowledge reproduced and evaluated in the waste management EPWP training activities (formal) and workplaces (informal)? 5. How does waste management knowledge circulate amongst the workers in the EPWP training activities and workplaces? For this study I used the case study method, focusing only on one field or DEA EPWP focus area (waste management) and one programme (EPWP Working on Waste), looking in more depth at two cases (two similar types of projects) within the EPWP Working on Waste programme, though they are situated in different areas and though I could only carry through observations of actual workplace training in one of the two sites due to contextual circumstances. The first project was situated in the Amathole District Municipality while the second one was situated in the Chris Hani District Municipality, both of which are in the rural towns of the former Transkei region in the Eastern Cape, South Africa. This area has been at the forefront in accessing funding for these projects due to the level of poverty surrounding these towns and the inability of the local government sphere to deliver on its mandate in the region. Data was collected through document analysis, questionnaires, interviews and observations. Documents analysed were research documents produced by researchers at the level of production as well as legal frameworks guiding waste management processes in this country. Qualifications and Unit Standards at Level 2, as well as training materials designed by providers were analysed. Training in one of the projects was observed and workers in both sites were interviewed twice. The main finding of the study is that waste management knowledge is characterised by interdisciplinarity and a strong epistemic relation which emphasises procedural and technical forms of knowledge. The study found that the knowledge constructed in the field, as well as the policies, qualifications and training programmes are all consequently characterised by a strong epistemic code (ER+) and a weak social relations code (SR-). The study also identified a ‘code clash’ with the knowledge of workers in rural towns whose knowledge and experience of waste management was found to reflect a strong social relation (SR+) and weak epistemic code (ER-), a pattern which was traced back to a similar code in waste management knowledge at home and school (i.e. workers’ prior knowledge and learning experiences). This created difficulties for the trainers who sought to use strategies of descending from the abstract to the concrete in various ‘descending’ semantic waves that tended to move from high levels of semantic density (SD+) to lower levels of semantic density (SD-) as the training provider sought to contextualise a range of concepts. This was the main strategy identified for mediating waste management knowledge reflecting a dominant pattern of SD+/SG- to SD-/SG+ (with SG meaning semantic gravity). This shows that the trainer seldom started mediating concepts from the basis of workers’ prior knowledge and experience and observations showed little responsiveness from workers resulting from this strategy. Despite this, the study found that workers did develop an improved understanding of specialised waste management knowledge over time, especially through observing and doing more complex tasks in the workplace. The study offers a model for addressing the pedagogical difficulty identified around the code clash, and suggests that further attention needs to be given to ‘ascending’ from the concrete to the abstract in pedagogical practices. The study also pointed to the need for a more inclusive knowledge framework for waste management training, especially in the field of recontextualisation (both the official and pedagogical recontextualisation fields) to extend possibilities for workers to learn more about economic potential and access routes into more sustainable jobs. It identifies the need for a more systemic approach to waste management in rural towns and municipalities, improved compliance and also proposes that better waste management practices are modelled to avoid performative contradictions between the knowledge promoted in the field of production and the official and pedagogical recontextualising fields and the field of reproduction, where workers are learning this knowledge via a mix of accredited training and exposure to participation in waste management practices. This study contributes to new knowledge in that it offers an epistemically grounded and theorised pedagogical process model for Level 2 Waste Management Training (in the EPWP programmes, but potentially also more broadly) that accords with the need for a strong epistemic relation code (ER+) embodied in the need for learning scientific and technical waste management knowledge and procedures. It also addresses workers’ needs for greater epistemic access and participation in knowledge building and application of waste management knowledge in praxis as per the purpose of the EPW training programmes, thereby potentially opening up more sustainable learning pathways for them out of poverty through the EPWP training opportunities. The study has pointed to key areas for further research, including further research on the proposed model, further research into Level 2 pedagogical practices and further research into the foundations of waste management learning in schools. Most of the workers who were participating in the training in the EPWP programmes were educated at above Level 2 before participating in the projects, yet their knowledge and experience of waste management was mostly based on everyday knowledge, pointing to an absence of adequate waste management education in schools in rural contexts in South Africa. The study has also made various recommendations for improving waste management education and training at Level 2 in EPWP programmes in rural areas in particular (but potentially also more widely), notably the need to develop a more inclusive knowledge framework that includes historical and economic knowledge more explicitly at all levels of the recontextualisation process; improved pedagogical and assessment practices that take better account of learners knowledge and experiences in knowledge building processes; and giving attention to structural and systemic approaches to waste management in rural areas to avoid performative contradictions that arise between the knowledge being promoted in the field of production and the field of reproduction and the actual context of waste management.

  • Description: Integrated algae pond systems (IAPS) combine the use of anaerobic and aerobic bioprocesses to effect wastewater treatment. Although, IAPS as a technology process offers many advantages including efficient and simultaneous N and P removal, no requirement for additional chemicals, O2 generation, CO2 mitigation, and a biomass with potential for valorization, a lack of technological advancement and the need for large land area, has limited the reach of this technology at industrial scale. In mitigation, peroxonation was introduced as a tertiary treatment unit and its effect on COD and TSS of IAPS treated water investigated. An effort was made to characterize the soluble but persistent COD in IAPS treated water and, productivity of the HRAOP mixed liquor was investigated to gain insight into the potential use of this biomass. Results show that peroxone treatment effectively reduced COD, TSS, and nutrient load of IAPS water without any significant impact on land area requirement. Indeed, summary data describing the effect of peroxone on quality of IAPS-treated water confirmed that it complies with the general limit values for either irrigation or discharge into a water resource that is not a listed water resource for volumes up to 2 ML of treated wastewater on any given day. Extraction followed by FT-IR spectroscopy was used to confirm albeit tentatively, the identity of the soluble but persistent COD in IAPS treated water as MaB-floc EPS. Results show that MaB-flocs from HRAOPs are assemblages of microorganisms produced as discrete aggregates as a result of microbial EPS production. A relationship between photosynthesis and EPS production was established by quantification of the EPS following exposure of MaB-flocs to either continuous light or darkness. Several novel strains of bacteria were isolated from HRAOP mixed liquor and 16S ribosomal genomic sequence analysis resulted in the molecular characterization of Planococcus maitriensis strain ECCN 45b. This is the first report of Planococcus maitriensis from a wastewater treatment process. Productivity and change in MaB-flocs concentration, measured as mixed liquor suspended solids (MLSS) between morning and evening were monitored and revealed that MLSS is composed of microalgae and bacteria but not fungi. Concentration varied from 77 mg L-1 in September (winter) to 285 mg L-1 in November (spring); pond productivity increased from 5.8 g m-2 d-1 (winter) to 21.5 g m-2 d-1 (spring); and, irrespective of MLSS concentration in late afternoon, approximately 39% was lost overnight, which presumably occurred due to passive removal by the algae settling pond. The outcomes of this research are discussed in terms of the quality of treated water, and the further development of IAPS as a platform technology for establishing a biorefinery within the wastewater treatment sector.

  • Description: This study is premised on the assumption that empowering the small-scale farmers in securing property rights and enforcement of these rights are the prime movers of agricultural development. Logically, it follows that by empowering small-scale farmers and giving them access to resources such as credits, subsidies and extension services the state can play a mediating role in transforming the agricultural land scape in Lesotho. Unless farmers are empowered the water resources in Lesotho will continue to serve the interest of the rent-seeking elite. Given the nature of the issues under investigation, the mixed research methodology (the use of both qualitative and quantitative methods) was used as a method of inquiry in order to get a deeper understanding of the phenomenon of water resources management and its subsequent impact on small scale farming in the rural areas of Lesotho. Both methods played a complimentary role by capitalising on both their strengths and weaknesses so as to provide various dynamics and linkages between the two variables of water resources management and small scale farming. The material condition of small scale farmers is intrinsically associated with the active state mediation in agriculture. Yet, the adopted Integrated Water Resources Management (IWRM) approach is still to materialise. This thesis, thus, argues that there is a need for a more holistic integrated water resources management framework that is livelihoods based and re-emphasises the need for conserving the ecosystem. Therefore, implementing a more holistic integrated water resources management approach is critical and vital in improving agricultural production and subsequently the livelihoods of small scale farmers and households. Although this thesis used Lesotho as the case study, it is hoped that the findings may provide tentative answers for other Sub-Saharan countries on how to properly and efficiently manage water resources so as to boost agricultural production amongst small scale farmers in order to improve human conditions and promote sustainable development in the rural areas.

  • Description: Rationale: Worldwide, hospitals with premature units have one generalised objective, i.e. to achieve postnatal growth and body composition similar to that of a normal foetus of similar gestational age. Optimal nutrition leads to optimal neurodevelopment and breastfeeding (BF) is known as the golden standard for infant nutrition. Human breast milk (BM) has significant value for preterm and term infants and is of special benefit to HIV infected mothers. Maternal supplementation is provided as part of the standard protocol in certain hospitals in the Eastern Cape province to those mothers who breastfeed their low birth weight (LBW) infants after delivery. human milk fortifier (HMF) is a nutritional supplement that is added to expressed breast milk for feeding preterm infants in order to meet their high energy and protein needs and therefore supporting the recommended growth velocity of 10g/kg/day-15g/kg/day. Some hospitals within South Africa provide HMF to preterm infants as part of their standard nutritional protocol in order for the infant to gain weight if BM only failed to produce adequate results. To date, little to no South African studies support or discourage the use of HMF for LBW infants. This study aimed to describe the effect of maternal supplementation compared with breast milk with HMF, or a combination of maternal supplementation and breast milk with HMF, on growth velocity in hospitalised LBW premature infants within the Nelson Mandela Bay health district. The proposed study design followed a longitudinal, observational, descriptive study in a cohort of LBW infants. The study was analytical using quantitative empirical data. Study participants were selected, by using convenience sampling, at Dora Nginza Hospital, Zwide between October 2015 and August 2016 (ethics approval: EC_2016RP27_564). Quantitative data on anthropometric measurements was collected from study participants. Primary care givers provided written informed consent. Registered nurses were trained and performed anthropometrical measurements according to standardised methods. A structured questionnaire was completed by the principal reasarcher as a source of data collection. Numerical data was described using means and standard deviations. Chi squares were used to describe the associations between maternal risk factors and birth weight outcomes. ANOVA was used to determine the relationship between growth velocity and the various supplementation groups. A sample size of 91 LBW preterm infants and mother pairs were entered into this study. The majority of mothers, 64% (n=58) fell in the age category of 20-35 years old. Of the total maternal sample (n=88), 35% (n=31) were classified in the at risk age category, i.e. <20years old and >36years old. Out of the total infant sample (n=91), 65% (n=59) was classified as VLBW, 22% was LBW and 22% (n=20) was ELBW. No statistically significant association was found between infant growth velocity and maternal risk factors. The group receiving BM with HMF had a mean growth velocity of 19.75 g/kg/day (SD=6.45) that was statistically significantly (p<0.05) more than the other groups. The maternal supplementation only group and the maternal supplementation and BM fortification group showed mean growth velocities of 12.26 g/kg/day (SD=5.41) and 12.29 g/kg/day (SD=6.97) respectively. A post hoc test was done between growth velocity in the supplementated groups and the length of hospital stay. These results reveal that the group receiving BM with HMF had a significantly (p<0.05) shorter mean length of hospital stay of 11.29 days (SD=7.02), compared with the group on the combination of maternal supplementation and BM with HMF. In this study, infants receiving HMF with BM showed the highest growth velocity with the shortest hospital stay before discharge. In this group, infants were already receiving an adequate BM intake of 150-180 ml/kg/day prior to participation in the study. This meant that the HMF group consisted of more stable preterm infants compared to the rest of the supplementated groups. However, a large proportion of participants in the maternal supplementation group also showed adequate to good growth velocity. The researcher recommends the implementation of maternal supplementation only, as standard of care for all hospitalised lactating women. Furthermore, timeous addition of HMF to expressed BM is necessary for infants with growth velocities <15 g/kg/day. This may save costs to the hospital as the use of HMF allowed for better weight gain and earlier discharge.

  • Description: Student activists in South Africa have put the decolonisation of higher education firmly on the agenda, demanding that researchers and teachers pay attention to something in particular that is very hard to hear and very possibly unhearable. These young, black South Africans are the intellectual force upon whom we are depending for the altered future of our country. We cannot change the circumstances which continue to frustrate and anger them without paying particular attention to them. Taking on the knowledge bases and knowledge generation in the Global South, they are demanding that we rethink the logos-based project of universities in South Africa. Their struggle is critically about how knowledge is implicated as a shaping force in lives which are still defined by colonial governmentality.

  • Description: This study uncovers and critiques the various ways in which Eben Venter‘s Trencherman (2008), Lauren Beukes‘ Moxyland (2008) and Lily Herne‘s Deadlands (2011) manifest an engagement with socio-political expressions of whiteness within post-apartheid South Africa. These overtly dystopian depictions of a country twenty-two years into its democracy reflect a level of anxiety felt by white South Africans attempting to negotiate the change in their socio-political circumstances. Within the alternate post-apartheid South Africa of Trencherman, whiteness comes to the fore as a socially constructed albatross preventing engagement with the trenchant effects of apartheid, as well as a grotesque bulging mass of unearned privilege embodied by a descendent of an Afrikaans farmer. Moxyland and Deadlands, however, portray a less overt engagement with whiteness by foregoing a critique of prevalent racial inequities. Instead, both authors favour an interrogation of South Africa‘s deleterious class hierarchy in settings that are fantastically futuristic and dystopic. This lends to my argument that the genre of speculative dystopian fiction has been sought out as an ideal space for white South African writers to (safely) deal with white anxieties. It is also pivotal to place these texts alongside one another to examine the ways in which white writers deal with whiteness as a marker of social privilege within the South African socio-political landscape. The theory of whiteness and the theories surrounding dystopian fiction will be used as integral theoretical frameworks for this study.

  • Description: The Expanded public works programme (EPWP) was a South African government initiative that was meant to fight poverty, reduce unemployment and develop skills for young people, women and people with disabilities. EPWP was to be implemented by the national, provincial and local governments in order to alleviate poverty and increase economic growth. The programme started with phase 1 in April 2004, where the objective was to create a minimum of 1 million job opportunities by March 2009. The target was achieved by the South African government, but many municipalities faced challenges as they were struggling to meet their own targets. EPWP phase 2 started in April 2009, where the target of creating 4.5 million work opportunities was set and it was meant to end in March 2014. Phase 3 was scheduled to start in April 2014 to March 2019. Buffalo City Metropolitan Municipality (BCMM) is a metropolitan municipality, which should implement EPWP, and it consists of the towns of East London, King Williams Town and Bisho. BCMM council accepted the EPWP structure in the financial year 2013/14, charging the Programme Manager to lead the EPWP unit, consisting of a single office to implement the programme. The municipality faced many challenges, in failing to meet the targets set by the National Department of Public Works (NDPW). These challenges include: the lack of political and administration commitment towards EPWP, lack of proper EPWP training and lack of accountability from Senior Management. Other challenges facing BCMM include: a lack of data capturers to consolidate EPWP information, lack of qualifies people to design and implement labour intensive projects and the shortage of staff within the EPWP unit, which was meant to support all departments. If the municipality can overcome all the challenges, the set targets can be met, unemployment can be reduced and poverty can be alleviated. There is an urgent need for the Mayor and Municipal Manager to commit themselves toward the full implementation of EPWP.

  • Description: My thesis compromises a variety of short stories which are modern re-writes of dark fairy tales. Fairy Tales often explore the dark side of human nature and in these stories I focus on the voices of female villains and the strange psychology which drives them. I find Fairy Tales absorbing because they reveal the vulnerabilities, dreams and fears of the human consciousness. My stories contain some satirical expositions of human nature and society. My influences are the anthology of short stories, “My mother She Killed Me and My Father He Ate Me”, The Grimm Fairy Tales (original) and The Fairy Tales of Charles Perrault as well as the writing of Horacio Moya, Angela Carter and Alissa Nutting for their dark satire and mockery of social eccentricities. Kate Bernheimer’s “Form is Fairy Tale and Fairy Tale is Form” is very influential in terms of the style it recommends in writing such as: “every day magic”, “flatness” (a form of narration), abstraction and intuitive logic.

  • Description: Unintended pregnancy remains a public health concern worldwide despite the availability of many contraceptives options. The South Africa Government introduced Implanon —a Long-acting Reversible Device— with aim to cost effectively prevent unplanned pregnancy. There are concerns that the implementation of this contraceptive option was without prior piloting to test for level of acceptance and attitude towards this contraception. Also, there is paucity of evidence on knowledge of women and their attitude to implanon as well as duration of use and reasons for discontinuation of implanon in South Africa. The present study address this gap by assessing the women’s knowledge of and attitude to implanon as well as reasons for implanon discontinuation in Buffalo City Municipality in South Africa. This prospective observational study administered a pre-validated questionnaire to 189 women who had removed implanon in the reproductive health clinic in one regional hospital and a primary health centre in Buffalo City Municipality. Descriptive statistics were used to analysis the study data. The average duration for implanon use among the participants was 11.2 months. Most participants had poor knowledge of implanon and implanon knowledge was significantly associated was with age. Most participants opined that implanon use is associated with heavy bleeding (60.7), irregular frequent bleeding (84.3percent), and weight gain (67percent). The main reason for implanon discontinuation was its side effects (71.3 percent). Other reasons for discontinuation of implanon are poor or wrong positioning (3.2percent), want to become pregnant (4.3percent). Some participants discontinued implanon because they were on treatment; 24 participants on ARV drug, one on antipsychotic drugs, and one on TB drugs. Experience of heavy bleeding (39.9percent) was the most stated side of implanon leading to implanon discontinuation. The study concluded that women, even though adopted implanon, lack knowledge of implanon mechanism of action and side effects. Poor knowledge of implanon side effects could explain its early discontinuation among women in South Africa. Provider should prioritise comprehensive counselling of clients on implanon side effects and mechanism of action in order to realise the benefit of implanon in this population.

  • Description: Financial retirement planning is an important component in ensuring that individuals accumulate sufficient wealth for retirement. Previous research suggests that many individuals are unable to accumulate sufficient wealth for retirement with the problem being particularly acute for women as they tend to spend less time planning financially for retirement when compared to men. Consequently, many women are unable to accumulate sufficient wealth for retirement. Despite the growing need to investigate women’s financial retirement planning, much research tends to focus on financial retirement planning for males. Consequently, there is a growing need to investigate women’s perceptions of successful financial retirement planning, particularly in Grahamstown. After conducting an in-depth literature study and using the study done by Doa (2014), six independent variables were identified: values, time horizon, attitudes, working life-cycle, risk tolerance and financial literacy. These independent variables were identified as factors which could potentially influence women’s perceptions of successful financial retirement planning. A set of hypothesis were formulated to test the relationship between these independent variables and the dependent variable (women’s perceptions of successful financial retirement planning). The study comprised of 101 participants. A principle component analysis was performed to determine the key variables, with the relevant independent factors being renamed: cultural values, personal values, affective attitudes, time horizon knowledge, time horizon consideration, risk tolerance, financial literacy. An ordinal logit regression analysis was then conducted on these renamed variables to determine the influence of these key independent variables on the dependent variable. After controlling for a set of demographic variables the results of the ordinal logit regression analysis revealed that only affective attitudes, time horizon knowledge, and personal values had a significant relationship with women’s perceptions of successful financial retirement planning. Cronbach’s alpha revealed that the measuring instrument of the significant extracted factors was reliable, while Pearson product moment was used to determine correlations between extracted key independent variables and the dependent variable. The investigation into women’s perceptions of successful financial retirement planning enabled insightful information to be gathered which adds to the body of knowledge. In addition, recommendations were formulated in an attempt to assist women when making financial retirement decisions.

  • Description: Over centuries, the external factors such as fire, low temperature, light or microbiological agents, act on the wood and induce some degradation processes, sometimes irreversible, identified by discoloration, fragility and unsightly appearance. Although there are numerous literature reports about different nanomaterials used for preservation and restoration of wood surfaces (calcium hydroxides, magnesium hydroxides, hydroxyapatite, or even organic resins as Paraloid B72), in this paper it is proposed a new system—gold hydroxyapatite (AuHAp), tested on the hazelnut wood samples (young and aged specimens), as a new solution for preservation of some wooden artifacts. This paper addresses a broad range of analytical methods: X-ray diffraction, UV–Vis spectrophotometry, Fourier transformed infrared spectroscopy, Raman spectroscopy, scanning electron microscopy with energy dispersive spectroscopy, chromatic parameters and hardness test. Also, humidity sorption/desorption measurements are used for humidity sorption and desorption evaluation. The adsorption and desorption tests determined the hydroscopic sorption properties of the wood specimens by measuring the mass of the specimens in equilibrium with air at a specific temperature and RH. All the results concluded that after the application of the new system on the hazelnut wood surface, a well distributed and uniform layer consisting from AuHAp systems with a network aspect are observed, which covers the wood vessels and fibers, filling the voids and stopping the wood weathering process, more accentuated at aged wood than at the young species.

  • Description: Woody plant encroachment in South Africa’s savanna-grasslands has been considered a rangeland management problem since the early 1900s. This phenomenon, which has been observed globally, is particularly important in Africa given the extent of tropical grassy biomes on the continent and their importance for rural livelihoods. In this study, local and regional scale approaches were used to investigate woody cover change in South Africa across the important savanna-grassland rainfall threshold of 650 mm mean annual precipitation (MAP). The aim was to test this threshold using remote sensing and demographic surveys in order to better understand the patterns, mechanisms and drivers of encroachment. Rates of encroachment and population demographics of Vachelia karroo were compared at arid and mesic savanna sites in the Eastern Cape, using time-series analysis of historical aerial photographs in conjunction with field surveys. Changes in the extent of woodland vs. grassland were then quantified at a national scale (1990-2013) by combining optical and synthetic aperture radar remote sensing data. This produced the first map of woodland- grassland shifts for South Africa and provided the basis for a spatially explicit investigation of the key drivers of change. The local studies revealed higher rates of encroachment at mesic sites than at arid sites, with a correlation between drought and rate of encroachment at the arid site. Vachelia karroo seedlings and stunted saplings were more prevalent at mesic sites than at arid sites and the growth form of adult trees differed significantly between sites. The national remote sensing investigation showed that woodland replaced grassland in over 5% of South Africa’s savanna- grasslands between 1990 and 2014, at rates consistent with other global and regional studies. Spatially explicit models showed a pattern of incremental expansion of woodland along a ‘tree front’ and complex relationships between woodland increase and fire, rainfall, terrain ruggedness and temperature. Overall, the local and regional scale findings of this work highlight the importance of the savanna rainfall threshold (~650 mm MAP) and the presence / absence of fire in understanding savanna dynamics and woody cover change in the context of global drivers such as elevated atmospheric CO2.

  • Description: Harmonious work relations can be achieved when worker involvement and participation structures are used effectively to ensure that workers‟ interests and rights are addressed. Literature has established the relationship between employee participation and worker satisfaction with working conditions. However, the extent to which employees are happy at work is also affected by their social and living conditions. It is therefore important to know the worker levels of satisfaction with participation on issues that affect them, and if the channels are being used to create an enabling environment. The objective of the study was to look at the influence employee participation has on worker satisfaction with work-life and workers satisfaction with social and living conditions, and the relationship between worker satisfaction with work-life and satisfaction with social and living conditions. The research questions were structured around this premise. The research was quantitative and used a 5-Likert scale using the three factors of employee participation, social and living conditions, and working life. The major findings revealed that there is strong relationship between worker satisfaction with employee participation and worker satisfaction with working life. Social and living conditions through an Exploratory Factor Analysis divided into exterior and interior social and living conditions. Working life was strongly correlated with interior social and living conditions.

  • Description: Curriculum transformation is a central concern for higher education in response to rapidly expanding technologies, globalisation and the widening diversity of the student and staff body. This is particularly true for South Africa, which is still grappling with inequalities and pressure for social redress in its universities. Early responses to supporting students took the form of add-on, ‘deficit-model’ approaches which understood poor student retention and success rates as emerging from students’ lack of neutral literacy ‘skills’. Recent initiatives have begun to adopt more socio-cultural understandings of literacy that seek to challenge traditional power structures and cultivate horizontal peer-orientated spaces for learning with a focus on practice rather than on product. Writing groups, as spaces for academic writing development, embrace this orientation and are argued to provide a transformative framework that foregrounds proactive student learning and experience, while still accommodating disciplinary learning through peer engagement. Drawing on the successful implementation of such forms of support at a research-intensive university, this paper argues that writing groups can play a critical role in both personal (student) transformation and broader curriculum transformation. Data include anonymous questionnaires and surveys with participants and coordinators of the writing groups. An inductive, constant comparative analysis indicated that students feel empowered in this space to develop not only their writing practices but also their transforming identities as scholars. Writing groups were found to provide ‘safe spaces’ where academic practices can be made explicit and where they can be challenged. The paper therefore argues that writing groups can play a small but key role in broader transformation efforts.

  • Description: I have written a collection of isiXhosa poems for my thesis. I was influenced by the conditions in life women often find themselves, as well as the cultural stereotypes that perpetuate these conditions. Writers who have had an impact on my writing are W. B. Rubusana, S. E. K. Mqhayi and J. J. R. Jolobe because of their language, rhythm and the richness of their writing more generally. It is as if they are voices of a past generation who reach out on us, today. More recent American poets such as Amiri Baraka, on the other hand, have shown me how poems can meet you, can come as bullets that pierce your heart, soul and brain. Combining these old and new poetic styles, I intend for my poems to be of value and benefit to women who seek mental, spiritual and physical healing.

  • Description: Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) or otherwise commonly known as the false codling moth is an indigenous pest of the citrus industry in southern Africa. The pest is highly significant as it impacts negatively on the export of fresh citrus fruits from South Africa to international markets. To control T. leucotreta in South Africa, an integrated pest management (IPM) programme has been implemented. One component of this programme is the baculovirus Cryptophlebia leucotreta granulovirus (CrleGV-SA) which has been formulated into the products Cryptogran™ and Cryptex®. It has previously been reported that there is a mutualistic association between Cydia pomonella (L.) (Lepidoptera: Tortricidae) also known as codling moth, and epiphytic yeasts. Cydia pomonella larval feeding galleries were colonised by yeasts and this, in turn, reduced larval mortality and enhanced larval development. It has been demonstrated in laboratory assays and field trials that combining yeast and brown cane sugar with Cydia pomonella granulovirus (CpGV) significantly increased larval mortality and lowered the proportion of injured apple fruit. This suggests that yeasts can enhance the effectiveness of an insect virus in managing pest larvae. In this study, we proposed to determine which species of yeast occur naturally in the digestive tract, frass and on the epidermis of T. leucotreta larvae and to examine whether any of these yeasts, when combined with the CrleGV-SA, have a synergistic effect in increasing mortality of T. leucotreta larvae. Firstly, Navel oranges infested with T. leucotreta larvae were collected from orchards in Sundays River Valley in Eastern Cape of South Africa. Larvae were extracted and analysed for the presence of yeast on their surface, or in their gut and frass. Four yeasts were isolated from T. leucotreta larvae and identified down to species level via PCR amplification and sequencing of internal transcribed spacer (ITS) region and D1/D2 domain of the large subunit (LSU) of rDNA region. These yeasts were isolated from the frass, epidermis and digestive tract of T. leucotreta larvae. The yeast isolates were identified as Meyerozyma caribbica, Pichia kluyveri, Pichia kudriavzevii and Hanseniaspora opuntiae. A yeast preference assay was conducted on female T. leucotreta moths to examine whether any of the isolated yeast species affected their oviposition preference. Navel oranges were inoculated with the isolated yeast species at a concentration of 6 × 108 cells.ml-1. The assay also included a Brewer’s yeast and distilled water control. Pichia kudriavzevii was shown to be the preferred yeast species for oviposition, as significantly more eggs were deposited on Navel oranges inoculated with this yeast compared to the other treatments. Lastly, a detached fruit bioassay was performed to evaluate the efficacy of mixing P. kudriavzevii with CrleGV-SA to enhance T. leucotreta larvae mortality. Pichia kudriavzevii was selected as it was demonstrated as having an effect on the oviposition preference of female T. leucotreta moths. The concentration at which P. kudriavzevii was applied remained the same as in the preference assay while CrleGV-SA was applied at lethal concentration required to kill 50 % of the population (9.31 × 107 OBs.ml-1). Although an increase in larval mortality was observed between CrleGV-SA being applied alone and the yeast/virus mixture, this result was determined not to be statistically significant. The experiments performed in this study provide a platform for further research into the application of a yeast-virus combination as a novel control option for T. leucotreta in the field. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2018

  • Description: Online communication has become a universal phenomenon, and a significant consequence of computer mediated communication (CMC) is the influence it has on self-disclosure. The aim of the present study was to explore and describe young adults’ perceptions of online self-disclosure, specifically what young adults’ self-disclose online and what psychosocial factors impact upon self-disclosure online. Bronfenbrenner’s Bioecological Systems Theory and the Johari Window were utilised as the theoretical framework of the study. The present study utilised a qualitative approach and was exploratory and descriptive in design. The sample size of the present study was 13, and semi-structured interviews were utilised as the method of data collection. The data obtained was analysed using thematic analysis, as outlined by Braun and Clarke. Six main themes were identified, namely Types of Online Experience, Online Self-disclosure, Information Disclosed Online, Differences between Online and Offline Self-disclosure, Privacy and Online Regrets. The findings of the present study will generate a better understanding of young adults’ online self-disclosure and can be utilised for future research.

  • Description: Current research in the sub-Saharan and other resource poor contexts indicates the largely negative social constructions of menstruation and menstruating women. Young men have been shown to reproduce these negative constructions and reinforce the stigmatized status of menstruation in these contexts. To my knowledge no studies have examined the ways in which young men talk about menstruation and menstruating women in South Africa. In this research, I aimed to explore the ways in which young men (in a resource poor area in the Eastern Cape) talk about menstruation in with their male peers in a focus group context and how this talk serves to enable specific subject positions (both masculine and feminine) that may reproduce, comply with and resist constructions of hegemonic masculinity (as outlined in previous South African research). By drawing on Raewyn Connell’s influential framework of masculinities and augmenting this with Margaret Wetherell and Nigel Edley’s contributions, this research adds to the growing body of research on masculinities in the South African context. I utilized a discursive framework in which to understand the interpretative repertoires drawn on in everyday talk about menstruation and the specific subject positions made available by these. Purposive sampling was used to recruit a total of 37 participants from two former Department of Education and Training schools in the Eastern Cape. Participants were young ‘black’ men with a mean age of 18.3 In analyzing and interpreting the data two overarching patterns emerged. In the first, the participants discursively distanced themselves from menstruation (and femininity in general) in order to avoid possible marginalisation and subordination in relation to local hegemonic masculine ideals. In doing this, the participants drew on a number of interpretative repertoires including: a dualistic repertoire, a bad (versus ideal) femininity repertoire and an abject femininity repertoire, which assisted in creating numerous subject positions. These subject positions allowed the young men to align themselves closer to hegemonic masculine ideals, and create distance by positioning menstruating women as the ‘other’. In the second overarching pattern, menstruation was constructed as a threat to masculine identity; within this construction, the young men discursively negotiated the ideological dilemmas surrounding this ‘highly feminine’ topic in ways that bolstered their positions within the gender hierarchy. Overall, hegemonic masculinities in this context were discursively reproduced and complied with in the participants’ accounts.
