- Description: In their official language policy, nearly all Sub-Saharan African states use their indigenous language(s) as Language of Learning and Teaching (LoLT) only at the beginning of primary schools. This is also the case in Malawi. The curricula in the various school subjects are also highly dominated by ‘Western’ ideas and include very little Indigenous Knowledge (IK). Nevertheless, indigenous languages are frequently used during lessons. This research focused on answering the following questions: How is a meaningful Science Education for pupils in Malawi possible? Does the inclusion of IK and teaching through African Languages assist pupils in any way? Research was done in the Northern Region of Malawi. To obtain a better understanding, semi-structured interviews and ethnographic observations were conducted. The main focus of these interviews was on the subject of ‘Agriculture’.

- Description: Book abstract. Securing Urban Heritage considers the impact of securitization on access to urban heritage sites. Demonstrating that symbolic spaces such as these have increasingly become the location of choice for the practice and performance of contemporary politics in the last decade, the book shows how this has led to the securitization of urban public space. Highlighting specific changes that have been made, such as the installation of closed-circuit television or the limitation of access to certain streets, plazas and buildings, the book analyses the impact of different approaches to securitization.

(Re-)inventing our selves/ourselves : identity and community in contemporary South African short fiction cycles.

- Description: In this study I focus on a number of collections of short fiction by the South African writers Joël Matlou, Sindiwe Magona, Zoë Wicomb and Ivan Vladislavić, all of which evince certain of the characteristics of short story cycles or sequences. In other words, they display what Forrest L. Ingram describes as “a double tendency of asserting the individuality of [their] components on the one hand and of highlighting, on the other, the bonds of unity which make the many into a single whole”. The cycle form, thus defined, is characterised by a paradoxical yet productive and frequently unresolved tension between “the individuality of each of the stories and the necessities of the larger unit”, between “the one and the many”, and between cohesion and fragmentation. It is this “dynamic structure of connection and disconnection” which singularly equips the genre to represent the interrelationship of singular and collective identities, or the “coherent multiplicity of community”. Ingram, for example, asserts that “Numerous and varied connective strands draw the co-protagonists of any story cycle into a single community. … However this community may be achieved, it usually can be said to constitute the central character of a cycle”. Not unsurprisingly, then, in its dominant manifestations over much of the twentieth century the short story cycle demonstrated a marked inclination towards regionalism and the depiction of localised enclaves, and this tendency towards “place-based short story cycles” in which topographical unity is a conspicuous feature was as pronounced in South Africa as elsewhere. However, the specific collections which are my concern here increasingly employ innovative and self-reflexive narrative strategies that unsettle generic expectations and interrogate the notions of regionalism and community conventionally associated with the short story cycle. My investigation seeks to explain this shift in emphasis, and its particular significance within the South African context.

- Description: How often do we notice the buildings that we work in, play in and live in? The architecture that we construct is specially geared to our human proportions, and shelters and accommodates us. It can be seen as a metaphor for the body, the self, and systems of social control that we have created. When the structure of this architecture is compromised, either literally or metaphorically, we experience instability and vertigo. My practical submission, Vertigo is concerned with architecture, perspective, deconstruction, instability, vertigo, scale and the body. Vertigo consists of paintings, ranging in scale from the size of a brick to the height of a single storey house. Utilizing a highly representational style as well as working with abstract sign systems and technical plan drawings, I destabilize firstly, our sense of certainty in the architecture that surrounds us, and secondly, prompts us to question the assumed fixity of ourselves and our social systems, through the convergence and collision of architecture and painting. This supporting document, (Un)stable Architecture as Deconstructed Meaning, considers the key conceptual concerns informing my practical submission. In chapter one of this mini-thesis: Deconstructivist Architecture, Instability and Impermanence I look at Deconstructivist Architecture which challenges traditional values of order, stability, harmony and unity of architecture. I position my work in relation to architecture projects on the Deconstructivist Architecture show in relation to their intent of undoing, shifting and destabilizing structure and what architecture is traditionally valued for. I also look at the shifting meaning and symbolism of architecture and skyscrapers. In the second chapter: Vertiginous Point of View and Shifted Perspectives I engage with vertigo, perspective, scale and the bodily analogy in architecture. I look at how Julie Mehretu destabilises built space and architecture in a painterly way, depicting multiple perspectives which are subjected to multiple interpretations. In chapter Three: Painting a Building and Building a Painting: Process, Scale and the Body, I discuss and engage with my practical submission, Vertigo, in relation to my process, scale, the body, vertigo, deconstruction, instability and perspective.

- Description: Language policy is an influencing factor of the educational outcome for pupils in Africa. Colonial languages have been largely used and African Languages are neglected. Despite this, the South African Constitution (1996) declares eleven official languages. However, curricular developments favour Afrikaans and English. To analyse the implementation of the official language policy, we focus on Limpopo Province. Over 1000 questionnaires were answered by teachers. This approach aimed to analyse the language practices and language attitudes of teachers. Schools in Limpopo showed significant differences between the official language policy and the daily language practices. Some teachers implement the official language policy; others use one or more African languages in their oral communications during the lessons in the form of Code Switching.

- Description: Commercial media entertainment offerings in South Africa especially mainstream soap operas, are progressively infusing dominant social values and ideas which are alien to South African tribal societies. In most of the commodified television drama series, people who hold tight to traditional beliefs and values are often characterised as traditionalists, while those who have imbibed the western defined dicta and ideology of modernity are seen as progressives. This study therefore, sought to ascertain how South African tribal language, traditional institutions, values, social norms and ancestral beliefs are portrayed through the television drama, Generations: The Legacy and what the viewers think about those constructions and the implication for cultural identity. The mixed methods approach was employed involving the administration of questionnaire to 350 participants selected through random sampling and a content analysis of 20 episodes of Generations: The Legacy. The findings suggest that Generations: The Legacy tends to portray South African tribal culture negatively (p-value > 0.05). More than half of the respondents (52percent) strongly believe such negative portrayals may erode the cultural identity of black South Africans, 68.6% were of the opinion that Generations: The Legacy gives preference to western culture as against South African tribal culture. The findings further showed that the African values and traditions represented in Generations: The Legacy do not significantly reflect the South African tribal tradition and values (p-value > 0.05). In the few occasions that African traditional values are represented Generations: The Legacy, they tend to be portrayed as old fashioned (p-value > 0.05), and inferior and backward (p-value > 0.05). In addition, the findings indicate that Generations: The Legacy is a vehicle for promoting dominant culture. Nearly, 59percent of the respondents stated that watching Generations: The Legacy affect the way they view South African tribal culture, while 59.1percent indicated that watching Generations: The Legacy has somehow affected their perception of their own cultural identity. In all, participants rated the representation of South African tribal culture as poor. The study concludes that while South African tribal culture is increasingly finding expression on mainstream soap opera, tribal South African values and beliefs are often depicted as old-fashioned, and inimical to modernisation, and individual’s freedom.

- Description: Rhabdosargus holubi (Steindachner, 1881) is a small (maximum size = 450 mm total length; Heemstra and Heemstra 2004) sparid that is distributed along the south-east coast of Africa from St Helena Bay, South Africa, to Maputo, Mozambique (Götz and Cowley 2013). Spawning occurs in the nearshore marine environment primarily during winter, specifically May–August in KwaZulu-Natal (KZN) (Wallace 1975) and July–February in the South-Eastern Cape (Whitfield 1998). Individuals reach 50% sexual maturity at approximately 150 mm standard length (SL) in the Eastern Cape (Whitfield 1998). The early life stages are transported by the south-westward-flowing Agulhas Current, and recruit as post-flexion larvae and early juveniles into estuaries during late winter and early summer (Blaber 1974). The warm temperatures and high nutrient levels in estuaries favour fast growth (Blaber 1973a), and fish spend their first year of life in these environments, migrating back out to sea after reaching approximately 120 mm SL. Some individuals remain trapped in closed estuaries, where they may reach sizes greater than 200 mm SL (James et al. 2007a). Rhabdosargus holubi is the dominant estuarine-dependent marine teleost species recorded in permanently open and temporarily open/closed estuaries in the warm-temperate region, which spans the south, south-east and east coast of South Africa (Harrison 2005). The species is also an important component of the linefishery in many SouthAfrican estuaries (10–15.6% by number) (Pradervand and Baird 2002), particularly in Eastern Cape estuaries (Cowley et al. 2003). These figures underestimate the presence of R. holubi, as most individuals making use of estuaries are young, feeding predominately on filamentous macroalgae and diatom flora, and are generally too small to be caught with hook and line (De Wet and Marais 1990). James et al. (2007b) showed that R. holubi made up 34–92% of the annual seine-net catch in the East Kleinemonde Estuary. Rhabdosargus holubi is also important in the KZN shorebased linefishery, representing 4.6% of the total landed catch (Dunlop and Mann 2012)More and more investigations indicate that genetic modification has no significant or persistent effects on microbial community composition in the rice rhizosphere. Very few studies, however, have focused on its impact on functional microorganisms. This study completed a 13C-CO2 pulse-chase labeling experiment comparing the potential effects of cry1Ab gene transformation on 13C tissue distribution and rhizosphere methanogenic archaeal community composition with its parental rice variety (Ck) and a distant parental rice variety (Dp). Results showed that 13C partitioning in aboveground biomass (mainly in stems) and roots of Dp was significantly lower than that of Ck. However, there were no significant differences in 13C partitioning between the Bt transgenic rice line (Bt) and Ck. RNA-stable isotope probing combined with clone library analyses inferred that the group Methanosaetaceae was the predominant methanogenic Archaea in all three rice rhizospheres. The active methanogenic archaeal community in the Bt rhizosphere was dominated by Methanosarcinaceae, Methanosaetaceae, and Methanomicrobiaceae, while there were only two main methanogenic clusters (Methanosaetaceae and Methanomicrobiaceae) in the Ck and Dp rhizospheres. These results indicate that the insertion of cry1Ab gene into the rice genome has the potential to result in the modification of methanogenic community composition in its rhizosphere.

The active methanogenic archaeal community in the Bt rhizosphere was dominated by Methanosarcinaceae, Methanosaetaceae, and Methanomicrobiaceae, while there were only two main methanogenic clusters (Methanosaetaceae and Methanomicrobiaceae) in the Ck and Dp rhizospheres. These results indicate that the insertion of cry1Ab gene into the rice genome has the potential to result in the modification of methanogenic community composition in its rhizosphere.

1986 WAGE Negotiations

- Description: The Liquor and Catering Trades Employees' Union have made big demands for higher wages and shorter working hours to the bosses of the hotels. This is because wages are far too low for hotel workers while working hours are very long. These demands will be discussed at the Industrial Council, where your union representatives will argue for big improvements in working conditions. But we can expect strong opposition from the bosses who have their own representatives on the Industrial Council. So the union campaign for higher wages will not be easy! But we must win it because workers and their families are suffering and the union campaign is our only hope. The fight will not be won at the Industrial Council, however - it will be won in the hotels. We have to build up the union's strength in each and every hotel so that the bosses see that we are determined to win our demands. This booklet will help you to build up the workers' organisation in your hotel. Use it to discuss the union campaign so that every worker knows what part he or she has to play.
