- Description: This study examines the extent to which material and social inequality in post-apartheid South Africa affect possibilities for poor citizens to gain access to mainstream spaces of mediated political deliberation. Access is problematized in terms of the possibilities that exist for poor citizens to ‘appear’ in these spaces as emancipated citizens with political agency. The study is motivated by a perception that South Africa’s middle-class and privileged citizens have more access to political deliberation because mainstream journalists pay more attention to their political concerns. Because mediated political deliberation provides a space for articulating the political will of citizens it is important that it reflects the multiple, and diverse range of voices that make up South Africa’s polity. If the experience of socioeconomically marginalised citizens is not registered in the same way as the experience of citizens with economic and political power, the balance of political decision-making continues to be skewed against the interests of the poor. Rather than a media-centric approach, the study centres on perceptions and views of poor citizens about their relationship with mainstream journalists. The study combines information from group interviews with citizens from Hangberg, Cape Town with 410 news reports in 18 mainstream newspapers about Hangberg citizens over a 20-year period. The interviews show that poor citizens feel largely excluded from mediated political deliberation; not because they do not appear in the news but because of how they appear in the news. The news reports confirm that mainstream journalists pay more attention to voices with political and economic power than to the voices of poor citizens. Even in news reports about Hangberg citizens, political leaders and non-governmental experts often talk about the problems in Hangberg more than the citizens of Hangberg themselves talk about these problems. Building on a relatively new scholarly interest in ‘active’ and ‘political’ listening in media studies and democratic theory (Bickford 1996, Dreher 2009, Couldry 2009, Dobson 2014, Wasserman 2013, Garman and Malila 2014), I consider listening as a constitutive element of the way in which journalists engage with poor citizens in mediated deliberative spaces. I ask whether different practices of listening can enable journalists to construct narratives that provide marginalised groups with different possibilities for equal access to, and participation in these spaces?

- Description: Many heat shock proteins (HSPs) are essential to survival as a consequence of their role as molecular chaperones, and play a critical role in maintaining cellular proteostasis by integrating the fundamental processes of protein folding and degradation. HSPs are arguably among the most prominent classes of proteins that have been broadly linked to many human disorders, with changes in their expression profile and/or intracellular/extracellular location now being described as contributing to the pathogenesis of a number of different diseases. Although the concept was initially controversial, it is now widely accepted that HSPs have additional biological functions over and above their role in proteostasis (so-called ‘protein moonlighting’).

Help or hindrance? a critical analysis of the agreement on sanitary and phytosanitary measures, and its effects on developing countries

- Description: WHILE it is accepted that the category of "developing country" is a broad one, it can nevertheless be acknowledged that the countries which fall within this categorisation share several common features. Such common features include their lack of financial resources and scientific capacity, and their reliance on trade in primary agricultural goods. The Agreement on Sanitary and Phytosanitary Measures was originally created to regulate trade in primary agricultural goods, and so its provisions are of great significance to developing countries. In its Preamble the Agreement acknowledges both the unique circumstances of developing countries and its desire to assist them in entering into and expanding within the international trading markets. As part of this endeavour, several provisions were included in the Agreement which purport to protect and provide for the interests of developing countries. In its inception, its Preamble, and the very nature of its content, the Agreement shows a desire to assist developing countries wherever possible. Unfortunately, a close analysis of the provisions of the Agreement shows that this desire has not been fulfilled. Many of the provisions of the Agreement are heavily skewed toward the interests of importing Members, often at the expense of developing Members - particularly those that export primary agricultural goods. Even the provisions of the Agreement which purport to provide protection and special and differential treatment specifically for developing countries frequently fall short, either as a result of ambiguous phrasing or poor textual interpretation by the dispute settlement bodies of the World Trade Organization. As a result, there exists a potential within the Agreement to have a significant detrimental impact on the international trading opportunities of exporting developing countries. In this thesis I analyse the provisions of the Agreement to determine where, why and how they are likely to have, or are having, a detrimental impact on developing countries (particularly exporting developing countries). After identifying these problems I examine and discuss several potential solutions and how they may be implemented to minimise - or even remove - the negative impact on developing countries and their international trading markets.

- Description: The electrocatalytic properties of a Co(II)octaalkoxyphthalocyanine complex (Co(II)Pc) with eight strongly electron-donating substituents provide the first example of the complete dechlorination of DDT through molecular electrocatalysis, rather than the use of metal electrodes which had been achieved previously. Interaction with a highly nucleophilic [Co(I)Pc]2− species results in rapid cleavage of the C(sp3) Cl, C(sp2) Cl and aromatic C(sp2) Cl bonds. Bis(p-chlorophenyl)methanone (BPCl2) is detected in high yield along with its full dechlorination product, diphenylmethanone (BP) and the conventional C Cl bond cleavage products, due to an unprecedented C C bond cleavage reaction that is followed by the formation of a C−O bond. Theoretical calculations are used to analyze trends in the electronic structure of the Co(II)octaalkoxyphthalocyanine complex that account for the efficiency of the C Cl bond cleavage reactions, and the reaction process and mechanism are analyzed in depth.

- Description: Recent factors identified as contributory to poor mathematics performance in South Africa include lack of parental involvement coupled by the divorce of mathematics education to children’s everyday lives. This exploratory study, therefore focused on home activities grandmothers engage their Grade 2 grandchildren that may promote mathematical skills of Foundation Phase learners. This study followed a qualitative, interpretive and case study research design, to explore home activities grandmothers engage their Grade 2 grandchildren that may promote mathematical skills of Foundation Phase learners. A small scale study of six grandmothers and three Grade 2 teachers were sampled through purposive and snowball sampling. In line with the protocol of the case study, semi-structured individual face to face interviews and shadowing were used to collect data. One striking feature of the main findings was the diversity mathematics applications home activities contained. These include physical, financial and fun playful home activities. Data also revealed that these home activities could reinforce numbers and what numbers mean; reinforce shape recognition and spatial relationships; complement matching, classification and sorting and reinforce measuring and time. This implies that curriculum must incorporate children’s social capital. Both teachers and grandmothers acknowledged that children’s mathematics education is complex and an effective partnership between grandmothers and teachers is needed if children are to be competent in mathematics.

- Description: The access to adequate housing is a constitutional right, in terms of Section 26 (1) of the Constitution of the Republic of South Africa, Act 108 of 1996. Access to housing in South Africa is still an ideal and not a reality. The increase in housing prices reduces affordability, which creates a barrier to the housing market for South Africans to fully participate. The South African housing market is divided, based on the affordability of households, with a gap within the property market. The gap-housing market is a market, which does not receive a government subsidy; and furthermore, it does not qualify for bond finance by the private financial institutions. The gap-housing market includes households that earn between R3,500 to R15,000 per month for residential properties valued between R116,703 to R483,481. The problem is a lack of supply in the gap-housing market to meet the demand; and this is also affected by the poor performance of the subsidy-housing market. The gap-housing market is not traded adequately, due to a lack of supply caused by stricter lending criteria from the banks. The study was conducted by means of reviewing the related literature and by an empirical study. A survey was conducted using the quantitative approach through a distribution of research questionnaires to different organizations within the judgement sample population. The objective of the study is to review the gap-housing market and to make recommendations. The descriptive survey was conducted among specialists that are participating in the South African housing market. The findings of the study suggest that there is a relationship between incentive and participation, as well as a relationship between participation – with access, supply and trading in the gap-housing market. This study will contribute to the South African housing market body of knowledge – by addressing the problem of a gap within the housing market.

- Description: This dissertation investigated the life experiences of homeless persons and how they come to view their self-concepts as homeless men. The theoretical framework that underpinned this study was the self-concept theory and social identity theory. In this contextual descriptive study, four homeless men between ages of 28-50 participated in the study. Data was collected by means of disposable cameras and recorded interviews. Thematic analysis was employed to analyse data. The study found that when the participants first became homeless, they encountered stigmatisation and were not ready to accept the homeless identity as it conflicted with their past identity. However, with prolonged homelessness, they took on the new identity and the roles that come with it. The study found that homeless men view themselves as worthless due to their experiences on the street which include living under inhumane conditions, victimisation, and stigma associated with being homeless. The participants have internalised the negative utterances from housed people, which has negatively affected their self-image to a point where they view themselves as worthless,useless and forgetable. The study also found that homeless men use various methods to survive on the streets, which were both self-enhancing such as participating in the informal economy such as car guarding, car washing and collecting tins in exchange for money; and self-destructive such as using substances, risky sexual behaviour. The participants were found to have low self-concepts because of the tough experiences they encounter on the street.

- Description: At the centre of rural development are household livelihood strategies. The livelihoods of South Africa’s rural African poor have long been characterized by diverse activities, and intertwined with urban opportunities. This study describes the livelihood strategies of rural households, identifies the determinants of these livelihood strategies and seeks to identify the role of preferences and household characteristics in changing livelihood strategies in Shawbury in the small town in Qumbu. It also identifies the relationships between household and individual characteristics and livelihood strategies. A random sampling technique was used to select 100 households in Shawbury. Descriptive analysis techniques were used to describe the characteristics of the households and livelihood strategies and to identify the relationships between household characteristics and livelihood strategy preferences, a multinomial logit regression model was used. The livelihood strategies used for the multinomial logit regression were commercial agricultural production/ production for selling; subsistence agricultural production/ production for consumption; non-farm employment; social grants and remittances. For much of the research available for livelihood strategies, tools such as the sustainable livelihoods framework have been the focus for studying the determinants of livelihood strategies; however, these tools have little to no consideration for the aspirations and preferences of the individuals in question. This study highlights some possible tools that could be used to examine the influence of aspirations and preferences on changing livelihood strategies including the consumer choice framework, the domestic development cycle, the social network framework for decision-making, the social systems approach and conjoint analysis. For this study, the actual preferences of livelihood strategies among the households are presented using conjoint analysis. This study finds that households in the same area have different characteristics and that livelihood strategies of Shawbury’s households are primarily non- farm, that include dependency on remittances, social grants and formal employment. It finds that households that generate income from wage employment (non-farm) and farm activities are better off than other households. Analysis of the characteristics of rural households also revealed that age, labour endowment, education, and land size holding are some of the barriers that poor households in rural areas face when attempting to enter into high-return livelihood strategies. The multinomial logit regression model has helped to identify some of the factors that influence the preference of certain livelihood strategies by households, are gender of the household head, age of the household head, size of the land owned, and educational level of the household head, household size, and livestock value. This analysis presents evidence about the relationship between household characteristics contributing to the adoption of certain livelihood strategies by people of Shawbury. The conjoint analysis has helped to identify that the most preferred to the least preferred livelihood activities are non-farm labour activities, crop production, animal production, contact with family/leisure and other natural resource based activities respectively.

It also identifies the relationships between household and individual characteristics and livelihood strategies. A random sampling technique was used to select 100 households in Shawbury. Descriptive analysis techniques were used to describe the characteristics of the households and livelihood strategies and to identify the relationships between household characteristics and livelihood strategy preferences, a multinomial logit regression model was used. The livelihood strategies used for the multinomial logit regression were commercial agricultural production/ production for selling; subsistence agricultural production/ production for consumption; non-farm employment; social grants and remittances. For much of the research available for livelihood strategies, tools such as the sustainable livelihoods framework have been the focus for studying the determinants of livelihood strategies; however these tools have little to no consideration for the aspirations and preferences of the individuals in question. This study highlights some possible tools that could be used to examine the influence of aspirations and preferences on changing livelihood strategies including the consumer choice framework, the domestic development cycle, the social network framework for decision making, the social systems approach and conjoint analysis. For this study, the actual preferences of livelihood strategies among the households are presented using conjoint analysis. This study finds that households in the same area have different characteristics and that livelihood strategies of Shawbury’s households are primarily non- farm, that include dependency on remittances, social grants and formal employment. It finds that households that generate income from wage employment (non-farm) and farm activities are better off than other households. Analysis of the characteristics of rural households also revealed that age, labour endowment, education, and land size holding are some of the barriers that poor households in rural areas face when attempting to enter into high-return livelihood strategies. The multinomial logit regression model has helped to identify some of the factors that influence the preference of certain livelihood strategies by households, are gender of the household head, age of the household head, size of the land owned, and educational level of the household head, household size, and livestock value. This analysis presents evidence about the relationship between household characteristics contributing to the adoption of certain livelihood strategies by people of Shawbury. The conjoint analysis has helped to identify that the most preferred to the least preferred livelihood activities are non-farm labour activities, crop production, animal production, contact with family/leisure and other natural resource based activities respectively.

- Description: Urban green spaces and trees provide multiple benefits to urban residents and the sustainability of cities. A poorly examined benefit is the provision of fodder to urban livestock. However, the presence and activities of livestock may be incompatible with other uses, although this has been little studied. We examined the impacts of livestock on trees and parks along a gradient of declining livestock density, complemented with a tree planting experiment to monitor damage. Neighbouring residents and park managers were interviewed regarding their perceptions of damage caused by livestock. The negative impacts on soil compaction, tree damage and death increased with increasing livestock densities. Thorny tree species were damaged significantly less (13 %) than non-thorny species (77 %), as were protected trees (25 %) relative to unprotected ones (65 %). There was more tree damage in public green spaces (PUGS) (54 %) than control sites (38 %). The majority of local residents felt that livestock should not be allowed in formal PUGS, and most urban park managers regarded livestock damage as a strong disincentive to plant trees. These results show the need for management of the trade-offs caused by livestock and greater appreciation of livestock as agents shaping aspects of PUGS.

- Description: The main objective of the study was to determine how phase feeding manipulation affects growth performance, feed cost, carcass characteristics and quality of meat from broiler chickens. A total of 180 day old un-sexed broiler chicks (Cobb 500) were separated into 3 dietary treatments of 60 birds per treatment and each treatment was replicated 3 times with 20 birds per replicate. The dietary treatments were as follows: T1 (starter 1-7 days; grower 8-21 days; finisher 22-35 days), T2 (starter 1-14 days; grower 15-21 days, finisher 22-35 days) and T3 (starter 1-14 days; grower 15-28 days; finisher 29-35 days). Feed intake and body weight gains were recorded weekly in kilograms. Average daily gain and feed conversion ratio were computed weekly. At day 35, the chickens were slaughtered and 12 representative breast muscles from each treatment were used for the determination of muscle pH (pH1, pH24 and pH48) and colour coordinates (Lightness – L*, redness – a* and yellowness – b*) in triplicate at 1 hour, 24 hours and 48 hours post-mortem.Feed intake (FI), feed conversion ratio (FCR), average daily gain (ADG) and average body weight at slaughter (ABW) were not significant (P>0.05) amongst the treatments. The most cost efficient feed (which accumulated the cheapest cost feed per kg were) T1 (R11.32) and T3 (R11.32) although there was a slight difference in the gross profit of these treatments T1 (R45.71) and T3 (R44.48). Carcass characteristics were the same (P > 0.05) across the treatments except for the wing, thigh, drumstick and the breast (P < 0.05). T2 had the highest wing weight (166.63±8.60), T1 (113.03±8.60) and the lowest in T3 (74.46±8.60). The thigh weight were greater (P<0.05) in T2 (185.69±4.34); T1 (185.54±4.34) compared to T3 (166.97±4.34) which was lower. Treatments 1 (204.17±6.57), T2 (197±6.57) had heavier (P<0.05) breast weights than T3 (186.06±6.57). Dietary treatments had no significant effect (P > 0.05) on pH of the breast meat. No differences were observed in colour during the 1 hour period after slaughter. At 24 hours after slaughter, the L* values were different (P < 0.05) in T1 and T2 (44.3 ± 0.37; 43.7 ± 0.37), respectively, T1 and T3 were the same. The a*-values were different (P < 0.05) at 48 hours after slaughter for T1 and T3 (4.5 ± 0.27; 3.4 ± 0.27), T2 was the same as T1. It was therefore, concluded that since manipulation of starter phase did not have adverse effects on growth performance, gross profit, slight statistical difference in meat quality attributes and carcass characteristics. Therefore, the manipulation of starter diet has the potential to be used in broiler production.

- Description: This dissertation discusses the application of additive manufacturing technologies for production of a large-scale rapid prototyping machine, which will be used to produce moulds for prototype composite turbine blades for the emerging renewables energy industry within the Eastern Cape region in South Africa. The conceptualization and design of three complete printer builds resulted in the amalgamation of a final system, following stringent theoretical design, simulation, and feasibility analysis. Following the initial product design cycle stage, construction and performance testing of a large-scale additive manufacturing platform were performed. In-depth statistical analysis of the mechatronic system was undertaken, particularly related to print-head locational accuracy, repeatability, and effects of parameter variation on printer performance. The machine was analysed to assess feasibility for use in the mould-making industry with accuracy and repeatability metrics of 0.121 mm and 0.156 mm rivalling those produced by some of the more accurate fused deposition modellers commercially available. The research data gathered serves to confirm that rapid prototyping is a good alternative manufacturing method for wind turbine blade plug and mould production.

- Description: My novella is about a mine worker and his family. Set in both Lesotho and South Africa, it engages the effects of migrant labour on families in post-apartheid South Africa. Told through the eyes of the different family members, the narrative uses shifting points of view and moves fluidly through time to present an intimate but complex view of the lives of ordinary working class people. It incorporates witchcraft and ghosts to reveal the blurred lines between the realms of life and death. This collection is inspired by my own father who is a former mine worker. I am influenced by Joyce Carol Oates and Chibundu Onuzo's darkly realistic style, Veronique Tadjo’s explorations of migration and death, the family chronicles of Chimamanda Ngozi Adichie and Yvonne Adhiambo Owuor. I am also inspired by female fantasy and horror writers such as those collected in Ann and Jeff VanderMeer’s anthology, Sisters of the Revolution: A Feminist Speculative Fiction Anthology.

- Description: Information and Communication Technology (ICT) has evolved into a pervasive commodity in modern enterprises. ICT enables enterprises, regardless of sector, to achieve their strategic objectives. Similarly, ICT is regarded as a critical enabler in South African municipalities to reach their objectives and ultimately deliver sustainable services to their communities. This dependence on ICT, therefore, necessitates a resilient ICT environment where minimal disruption to ICT is a primary goal. Unfortunately, as reported by the Auditor-General of South Africa, the majority of South African municipalities are neglecting to address the continuity of their ICT services. Failing to implement adequate ICT continuity controls restrict these municipalities from achieving their strategic goals and, as a result, fulfilling their constitutional mandate of service delivery. It is, therefore, the objective of this study to devise a method, consisting of a theoretical foundation and a supporting tool-set, to assist municipalities in addressing a real-world ICT continuity problem. This method aims to be scalable and usable within different municipalities, and be simplistic and comprehensible enough to implement. The theoretical foundation will introduce the concept of ICT Readiness for Business Continuity, based on the recommendations of international best practices and standards, for example, the ISO 27031 (2011) standard. Furthermore, by considering various challenges within local government, the tool-set will ultimately help municipalities to help themselves in this regard.

- Description: Many of the larger estuaries along the South African coastline are highly degraded due to human impacts, highlighting the need to conserve pristine systems. There are approximately 100 micro-estuaries along our coastline which have not yet been identified or classified and hence their ecological functioning is unknown. The aim of this study was to identify and classify micro-estuaries along the Eastern Cape coast. Specific objectives of the study were to: 1) map the distribution of estuarine habitats in a selection of micro-estuaries and assess changes over time; 2) measure the physico-chemical characteristics of the micro-estuaries in the field; 3) investigate the distribution of vegetation, identify macrophyte species and habitat integrity and classify the micro-estuaries sampled using abiotic and botanical characteristics. A total of 30 systems were identified of which 10 were selected for sampling which took place seasonally (2015-2016). A relationship between open water surface area and short term rainfall was only evident in Cunge, Sandy Bottom and Ichabana. In the field it was observed that after heavy rainfall, open water surface area increased and mouth breaching occurred. Salinity was the only water column characteristic that showed differences; salinity increased in response to over wash events. Sand was dominant in all systems and there were no differences in sediment characteristics. A total of 8 macroalgal species, 16 estuarine macrophyte species, six freshwater species and 72 riparian plant species were found. Seed bank reserves were low in all systems despite them being vegetated. Only abiotic characteristics were used for classification using Principle Components Analysis since there were no botanical differences between systems. Micro-estuaries were larger (> 0.03 ha), had a higher salinity (oligohaline, mesohaline and polyhaline conditions) and a constant water body. Micro-outlets were smaller (< 0.03 ha), had a lower salinity (oligohaline conditions were most common) and showed periods of drying. Five micro-estuaries (Shelbertsstroom, Kwesani, Cunge, Mtwendwe and Mtendwe) and five micro-outlets (Stromatolite, Sandy Bottom, Ichabana, Palm Tree and Black Rock) were classified. This study has shown that the micro-estuaries along the Eastern Cape coast are pristine (i.e. intact riparian zone and catchment), untouched and highly dynamic systems (i.e. great variation in water surface area and mouth condition) highlighting their need for protection.

This study has shown that the micro-estuaries along the Eastern Cape coast are pristine (i.e. intact riparian zone and catchment), untouched and highly dynamic systems (i.e. great variation in water surface area and mouth condition) highlighting their need for protection.

- Description: Environmental growth conditions and mechanisms involved in sediment transport by needle ice have historically been difficult to assess and are poorly documented. The spatial and temporal dynamics that relate to the environment, growth and decay of needle ice are not fully understood. This study monitored needle ice growth, melt and visually identified sediment displacement mechanisms by needle ice, with the aim of revealing environmental growth criteria, timing of growth/melt, ground-surface-air energy balance and sediment displacement mechanisms. Furthermore, the impact of needle ice displacement on vegetation and patterned ground formation was analysed. High-frequency visual monitoring, using three cameras, supplemented by high-frequency measurements of air temperature, soil moisture and wind speed was used to investigate needle ice growth and decay dynamics. Results from visual and environmental monitoring of needle ice growth, showed that the needle ice growing environment was more dynamic, especially in terms of surface temperature, than previously argued. Needle ice growth was observed to occur during surface temperatures from -2.0°C to 2.2°C, soil moisture levels from 0.4% to 37.4% and in winds speeds of 0 m/s to 12.6 m/s. Needle ice initiation was documented a few minutes to hours before or after the onset of surface temperature dropping to below 0°C. Imagery displayed that the depth of ice nucleation was variable within the soil column, possibly relating to the energy balance of radiative cooling, convective heat loss, ground conductivity and latent heat release at the air-surface-ground boundary. Heaving and resettling, toppling and rolling were identified as slope displacement mechanisms when needle ice decayed. Animal trampling and hail were additionally documented as substantial surface altering processes. Furthermore, no impact of needle ice reducing vegetation stability was identified, although a tendency to hinder vegetation expansion was noted. Also, no creation of patterned ground was observed as a result of needle ice decay.

- Description: In today’s dynamic market, it is crucial that logistics systems understand their activities and processes in an efficient way. Lean, in essence, is a method to assist companies in rendering efficient services to customers (Andrejic, 2013, p. 84). The Lean approach for waste elimination can be applied to many different types of operations whether in manufacturing or service industries. The identification of warehousing wastes is sometimes considered difficult in its identification within processes (Villareal, Garza, Rosas & Garcia, 2012, p. 278). The purpose of this case study is to contribute to finding a solution for the decreasing operational efficiency in the operation under study. The researcher found that this paper filled an important research gap in terms of offering management of the selected logistics institution a better understanding of the different waste types in each process. Operational areas such as receiving, unboxing, put-away, picking and issuing were examined as possible reasons for concern about service orientated wastes. The research was conducted through observations and thereafter a questionnaire was distributed amongst a sample of 40 employees within a specific logistics institution. The study discussed certain key factors in Lean, specifically focusing on the types of waste in a service environment.
