- Description: During the past decade, the sophistication and maturity of Enterprise-level Information Security (EIS) Standards and Systems has increased significantly. This maturity, particularly in the handling of enterprise-wide capability models, has led to a set of standards – e.g. ISO/IEC 27001, NIST 800-53, ISO/IEC 27789 and CSA CCM – that propose controls applicable to the implementation of an Information Security Manage-ment System (ISMS). By nature, the academic community is fruitful in its endeavour to propose new password schemes; and Graphical Passwords (GPs) have had many proposals for schemes. In this paper, we explore the impact of good security standards and lessons-learnt over the past decade of EID as a model of constraint on GPs schemes. The paper focuses on a number of GP schemes and points out the var-ious security constraints and limitations, if such schemes are to be im-plemented at the enterprise level.

- Description: This thesis examines an aspect of economic and technological history which has been little explored in South African history. It argues that the military subjugation and the economic development of the Cape Colony, and particularly of the Eastern Cape, were contingent upon good transportation. The geography of the country, which included relatively impassable mountains and numerous often flooded rivers, necessitated bridges as well as roads. Both were expensive. As a leader in industrial technology, Britain was well placed to extend bridge-building skills to its colonies. This thesis examines the processes by which a small and undeveloped colony strove to create an efficient technological infrastructure. As wagon traffic increased through progress, delays in crossing rivers became a hindrance leading to agitation for bridges. It will be shown that the construction of wagon bridges over the numerous rivers encountered in the Eastern Cape Colony was imperative for the initial free flow of military forces and for later commercial expansion as new towns were established. The eastward expansion was led by the military during the frontier wars followed by the Royal Engineers who built roads and bridges along the eastern frontier. The new Colonial Secretary John Montagu, who arrived in 1843, boosted the colonial finances by overhauling the administration. He established the Central Road Board, an organisation that would drive the building of mountain passes, roads and bridges. The Public Works Department succeeded the Central Road Board and with the financial intervention of the Crown Agents for the Colonies, carried on with an extensive programme of road and bridge building. From the 1870s wagon bridge building lagged behind the huge railway building enterprise in response to the opening up of the diamond and gold mines. The final quarter of the 19th century saw increased bridge building activity in the Eastern Cape with the construction of many iron lattice girder, stone masonry arch and timber trestle bridges. The surviving bridges remain as mute testimony to the skill and expertise of British engineers such as Lewis, Woodifield, Robinson, Fforde, Wakefield, Berkley, Grier, Newey, Westhoven and others.

- 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: 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: 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: Participatory action research aims to reduce power differentials in research. In this chapter we problematise the blurred boundaries when a participant becomes a researcher. We re-flect on a PhD undertaken by the first author who was a mem-ber of a social enterprise in the UK that provided user-led re-search and training with a diversity of communities. Experienc-es of ten members of the collective were gathered through creative arts-based methodologies designed to be inclusive. We describe three tensions that arose when trialling participa-tory video production, when data analysis could not be under-taken collaboratively, and when reflecting on the solitary nature of PhD thesis writing. We outline the ways these tensions were worked through and explore ways of writing about participatory research in a PhD thesis.

- 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: 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: 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: 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

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: 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.

- Description: This study examines the changing roles of graphics journalists in the digital era at Graphics24, the largest information graphics newsroom in South Africa, in the context of their work for Netwerk24, an online news site published in Afrikaans with a strong focus on mobile-first news. The study examines the discursive construction of these new journalistic roles in the digital era where even the core conceptualisation of what journalism is, is being re-examined. It considers external factors affecting the discourse of change, drawing on a hierarchy of influences analytical model, as well as norms specific to the creation of information graphics. Data for this study was gathered by using ethnographic immersion and semi-structured interviews. This study specifically looks at graphics journalists working in a mobile-first environment, and how the pressures of producing information graphics for consumption on smartphones affects their roles. Evidence of two widely differing discourses in the Graphics24 and Netwerk24 newsrooms was found. Visual journalists in this study have created a discourse around being distinct “service providers”, rather than mobile-first journalists, who do not see the need for full integration in the fast-paced mobile news environment of Netwerk24. Word-centric journalists have, by contrast, created a mobile-first discourse. They experience the separateness of the graphics team as a barrier that impedes the creation of good information graphics for mobile phone consumption. Although this is a very localised study in a very particular context, this study contributes to broader thinking in what is a very under-researched field: The changing roles of visual journalists in the digital era and the discursive construction of these roles. The study suggests that even in the digital era where the definition of newsrooms has become much more fluid and less fixed physically, ethnographic methods can still offer a meaningful way to explore journalistic roles.

‘I don’t belong nowhere really’: the figure of the London migrant in Dan Jacobson’s ‘A Long Way from London’ and Jean Rhys’s ‘Let Them Call It Jazz’

- Description: Publisher version , In this article we compare and contrast the figure of the migrant, central to Dan Jacobson’s short story ‘A Long Way from London’ ([1953] 1958. A Long Way from London and other stories. London: Weidenfeld & Nicholson), and to Jean Rhys’s short story ‘Let Them Call It Jazz’ ([1962] 1987. The Collected Stories. New York: Norton), both of which are set in London in the early to mid-twentieth century. The main argument is that these figures, as migrants in London from South Africa and the Caribbean respectively, similarly occupy a liminal space despite stark differences in class, race and gender. In both stories this liminal space is described through evocations of London as a hostile diasporic space, lacking in hospitality, and experienced by the migrant figure as a place of confinement and incarceration. Also, both stories utilize the technique of silence or lacunae when it comes to issues of specific discrimination and abuse, such as racism or sexual exploitation. For the purposes of comparison, the character Manwera from ‘A Long Way from London’ and, Selina, the protagonist of ‘Let Them Call It Jazz’, are selected for analysis. Particularly, their respective responses (Manwera’s pride and dignity, and Selina’s recovery after a breakdown, and her musical talent) to the exigencies of migration are suggestive of ‘adaptive strength’ (Steve Vertovec and Robin Cohen [1999] 2001. Migration, Diasporas and Transnationalism. Cheltenham and Northampton MA: Elgar Reference Collection, xviii), a common feature in transnational literature which attempts to celebrate liminality and multiplicity as key characteristics of a transnational subjectivity. In addition, the protagonist of ‘A Long Way from London’, Arthur, offers a contrast to Manwera and Selina, not only because of race and class, but because he is depicted as having adapted to and assimilated into British culture, while being strangely detached from and ambivalent about both homeland and diasporic home. Varying forms of adaptive strength are portrayed in both stories, but they close with intimations of bleak futures for the migrant figures. The essay thus concludes with the observation that in these two stories, the figure of the London migrant is rendered as facing further grave challenges, and that all three figures ‘belong nowhere’ (Rhys [1962] 1987 Rhys, Jean. [1962] 1987. The Collected Stories. New York: Norton. [Google Scholar] , 175).

- Description: Early adolescence (ages 10 - 14) is a crucial stage of development. The importance of early intervention in improving adolescent sexual and reproductive health (SRH) is increasingly acknowledged. Yet, school-based sexuality education largely focuses on older adolescents, leaving very young adolescents to contend with conflicting information from different sources. This study responds to the need for contextually nuanced research with very young adolescents, which can inform policy and programmes aimed at improving their SRH outcomes.
