- Description: A number of South African women writers have taken up chick-lit as a form of writing that enables them to reflect on the experiences of the modern woman in post-apartheid South Africa. The protagonists portrayed in chick-lit narratives occupy ambiguous positions: they may have benefitted from feminist politics, which has opened new possibilities for them; however, underlying this emancipation is an implicit collusion with patriarchy. Chick-lit refuses to offer a clear-cut construct of women’s lives; instead, it suggests a problematic terrain that is inherently ambiguous and contradictory, simultaneously empowering and oppressing women. It depicts a realistic world where contemporary women critique patriarchy and attempt to break free of its stranglehold by finding new methods of self-realisation. In this article, I argue that as a genre chick-lit offers a space of recognition and reflection for women who share a similar world view and emotional knowledge that stems from a common historical experience.

- Description: This study describes Nigerian and South African students' conceptual understanding in high school geometry based on the van Hiele model of geometric thinking levels. The study further highlights students' misconceptions in school geometry. Concepts of triangles and quadrilaterals were investigated among 36 mathematics learners drawn from grades 10 through 12 who participated in this study. The tasks included identifying and naming shapes, sorting of shapes, stating the properties of shapes, defining of shapes and establishing class inclusions of shapes. The results indicated that many Nigerian and South African high school learners in Grade 10, 11 and 12 hold a number of misconceptions about geometric concepts of triangles and quadrilaterals.

‘It's just taking our souls back’: discourses of apartheid and race

- Description: Although apartheid officially ended in 1994, the issue of race as a primary identity marker has continued to permeate many aspects of private and public life in post-apartheid South Africa. This paper seeks to understand how youth at two South African tertiary institutions position themselves in relation to race and the apartheid past. Our data include four focus group interviews from two universities, one which can be described as historically ‘black’ and the other as historically ‘white’. Given the complex nature of the data, we elected to use a combination of corpus linguistics and discourse analysis as our methodological approach. We explore how words such as black, white, coloured, they, we, us and them feature in the interviews. Our analysis shows that the positioning by the interviewees reflects a complexity and ambivalence that is at times contradictory although several broader discourse patterns can be distilled. In particular, we argue, that all groups employ a range of discursive strategies so as to resist being positioned in the historical positions of ‘victim’ and ‘perpetrator’. Our paper reflects on these findings as well as what they offer us as we attempt to chart new discourses of the future.

- Description: To most of us, speech comes more readily than writing, and when information has to be passed on, the obvious way of doing it is by word of mouth. The telephone has greatly widened the opportunity of conducting business in this way. But a trade unionist is well advised not to rely on this method alone. In the affairs of the heart, it may be good advice never to put anything in writing. The reverse is often true in business. What is written, especially if carbon copies are kept, survives as a record. The record remains as a reminder of what has happened, and a check in the event of a dispute. It is only too easy during transactions which may take some months, to forget exactly what had happened at any one time. Written records will provide exact information, not only about what happened but — what is often as important — when it happened. When it is remembered that the actions of shop stewards and branch officers may be vital evidence in a Court of Law, as for example in the pursuit of claims for damages on behalf of union members, exact records are extremely important. For this reason, a duplicate copy of letters provides branch officials with lasting evidence of their own communications. All branch letters, therefore, should be written in duplicate. If letters are typed or written in an interleaved correspondence book, it is easy to make carbon copies. But even if letters are hand written on loose sheets, ordinary carbon paper will make clear copies providing a fountain pen with a fairly hard nib or a bail-point pen is used.

Understanding its richness and complexity requires a study carried out from various points of view. Particular attention to culture is essential. Centered on the work of visual artists and performers, on town planning, literature and spirituality, the essays gathered here call on many disciplines: art history and history, anthropology, sociology, geography, architecture, comparative literature, visual and culture studies. They constitute a network of crossed views on a subject which no serious reflection on globalization can do today.

- Description: preprint , There can be few recent theatrical productions in greater need of interpretative effort than Welcome Msomi’s Umabatha. From its inception debate has raged over the cultural status of the production: was it an authentic expression of Zulu culture, or a tacky piece of ‘blacksploitation’? – to use Russell Vandenbroucke’s term. Was the production pleasing evidence of Shakespeare’s universality, a gift to the colonies returning joyfully to the motherland with interest accruing? Could it perhaps be a case of Zulu culture triumphing over Shakespeare, native invention swamping and overwhelming a colonially-imposed ‘high culture’? Was the show performing ‘Africa’ for the world and, if so, was this the way Africa ought to be represented in the twentieth century? Or were we perhaps looking at a fetishized theatrical commodity, wrenched from any authentic cultural roots, and circulating aimlessly but profitably through a globalised theatrical cosmopolis? Such speculative questions – and there are many others – have regularly jostled each other in the bulky heritage of Umabatha’s reception history. The central problem underlying this chapter is whether it might not be possible to define a basis for a more objective response to some of them, so that the issues involved no longer rest quite so slackly in the realm of mere critical opinion.

- Description: This paper reports on an international collaborative study that investigated how students from rural contexts negotiate the transition to university, and how prior cultural and educational experiences influence their higher education trajectories. A qualitative, participatory methodology was adopted, centred on co-researcher narratives, digital artefacts and discussions. Findings demonstrate how family and community, including religious, study, and self-help groups, influenced their transitions into higher education and journey through university and to their identities, agency and sense of belonging. The paper argues that university practices, values and norms need to acknowledge and incorporate all students’ prior experiences and histories and recognise their powerful contribution in working towards a decolonial higher education.

South Africa is no different but additionally has an overarching aim of achieving social and labour market ‘transformation’ to move away from the legacy of the apartheid era. The effectiveness of incentives provided to the film and television sector in South Africa are considered in terms of their stated objectives of job creation, skills and knowledge transfer and the attraction of foreign direct investment. Informed by empirical analysis of incentive scheme data and supplemented by elite interviews with key informants, some specific policy revisions are proposed.

As such, it utilises photographic and autographic traces to 'track' the elusive traces left by Nilsen. Given the lapse of two decades between Nilsen's arrest and Smith's visit, the traces of Nilsen's 'wrongs' seem all but erased by the banal façade of suburban living which has continued on, regardless. In taking this as a starting point, the following article considers the motif of absence that characterises Smith's work as intrinsic to traces per se.

- Description: preprint , Time-resolved luminescence spectra of low sensitivity natural quartz from crystalline rocks are presented. The luminescence was pulse-stimulated at width using 470 nm blue light from quartz separated from plutonic, metamorphic, volcanic and hydrothermal samples. Measurements were made at 20 °C. All samples show evidence of a short lifetime component less than long although in several cases too weak in intensity to be evaluated accurately. On the other hand, the value of the principal lifetime component varies considerably being about in metamorphic quartz, in plutonic quartz, and in one example of hydrothermal quartz. The results illustrate a new feature of luminescence from quartz for which lifetimes less than or greater than have never been reported at room temperature before. It is argued that the thermal provenance of the quartz and so the annealing it will have experienced influences the size of the observed lifetime. In particular, the results are explained in terms of a model consisting of three luminescence centers with the dominant lifetime linked to preferential recombination at one center depending on the thermal history of the sample and hence the hole concentration of the center.

- Description: Small pelagic fish, including anchovies, sardines and sardinellas, mackerels, capelin, hilsa, sprats and herrings, are distributed widely, from the tropics to the far north Atlantic Ocean and to the southern oceans off Chile and South Africa. They are most abundant in the highly productive major eastern boundary upwelling systems and are characterised by significant natural variations in biomass. Overall, small pelagic fisheries represent about one third of global fish landings although a large proportion of the catch is processed into animal feeds. Nonetheless, in some developing countries in addition to their economic value, small pelagic fisheries also make an important contribution to human diets and the food security of many low-income households. Such is the case for many communities in the Zanzibar Archipelago and on mainland Tanzania in the Western Indian Ocean. Of great concern in this region, as elsewhere, is the potential impact of climate change on marine and coastal ecosystems in general, and on small pelagic fisheries in particular. This paper describes data and information available on Tanzania's small pelagic fisheries, including catch and effort, management protocols and socio-economic significance.

- Description: Imagine, as one may well imagine at this time of the day, a chocolate mousse, dark and delectable, or a tempting tiramasu or a perfect pavlova. How are you going to decide which is best? Yes, indeed the actual presentation of the puddings may influence your choice, but to be able to make an informed choice, you would need to taste them. Do you have to make the choice according to your own taste, or do you have to decide which should go best with your menu for your dinner party? If you have to decide which is best, you would have to be able to rank them in relation to other mousses, tiramasus or pavlovas. You need to know the ingredients, and for a professional decision you would need some knowledge of the art of cooking. Proof in the art of cooking, science, and also in law depends on the quantum and quality of evidence or data sufficient to support a conclusion. Loevinger concludes that “[p]roof ultimately depends on the ability of the human mind to make appropriate and useful distinctions and connections among data or items of evidence”.

- Description: The Nyl River floodplain wetland, one of South Africa's largest floodplain wetlands and a Ramsar site of international conservation importance, is located in an area of long-term and still active valley sediment accumulation. Creation of accommodation space for sedimentation has previously been attributed to tectonic controls, but new investigations reveal that a more likely cause is progradation of coarse-grained tributary fans across the narrow river valley downstream of the main area of floodplain wetland. Obstruction of trunk river flow and sediment transfer by these tributary fans has led to backponding and upstream gradient reduction and to accumulation of valley fills up to ∼35 m thick. Chronological control for the timing and rate of sediment accumulation is limited, but we hypothesise that a semi-arid to arid climate, characterised by asynchronous trunk–tributary activity that results in marked discontinuities in downstream water and sediment transfer, is likely to have been a key control. These interpretations are supported by other studies of dryland rivers globally and the findings add to our growing understanding of the controls on the origin and development of southern African wetlands, particularly by demonstrating how the combination of a particular physiography and a dryland climate can impart some distinctive geomorphological characteristics.

The life history responses of the abalone pest, Terebrasabella heterouncinata, under natural and aquaculture conditions

- Description: The sabellid, Terebrasabella heterouncinata, is a small (<5 mm) intratubular brooder that lives in burrows within the host s shell matrix. It is a semi-continuous breeder and despite producing small numbers of large eggs, infestation by this animal has reached epidemic proportions on local abalone farms. The present study compared the morphometrics and reproductive characteristics of worms from farmed and wild abalone, in the Walker Bay area of the south Western Cape Province of South Africa, to gain insights into why this animal has become so successful under aquaculture conditions. The farms designated farm A and farm B each had one on-farm site, and two wild sites, while farm C had two on-farm sites and two wild sites. The wild sites were natural abalone habitats located within 2.5 km of the farms. Our results conclusively showed that environmental conditions prevalent on the farms enhanced the reproductive success of these worms relative to that observed in its natural environment. At farms B and C, worms occurred in significantly higher densities at the on-farm sites than in the corresponding wild samples, but at farm A, density was equally low at the three sites. At all three farms, a greater proportion of the population was reproductively active in the on-farm samples than in the wild samples. Worms on farmed abalone had a higher instantaneous fecundity, brooded more clutches simultaneously and were larger than their conspecifics from the wild. There was a positive correlation between adult size and brood size and the number of clutches brooded simultaneously. Within the three on-farm sites there was a negative correlation between egg volume and brood size, indicating a trade-off between these traits. However, such a trade-off was not apparent between sites, with brood size being higher at the on-farm sites than at the wild sites, irrespective of egg size. This suggests that the stable nutrient-enriched environment on the farm led to an increase in fecundity without compromising the size (and implicitly the quality) of the eggs. Worm density did not have a significant effect on body size or any other reproductive traits at most sites, and the density of T. heterouncinata was unaffected by the density of other shell-infesting polychaetes. The results suggest that the farm environment has selected for larger, more fecund worms that breed rapidly with high recruitment success as a consequence of abundant nutrients, high host density, habitat stability and a possible lack of predation and interspecific competition.

- Description: In sharp contrast to the debates concerning land policy, land tenure and sustainable resource management in South Africa is any input concerning the geographical distribution of land productivity. This paper attempts to redress this imbalance by providing an empirical investigation of land potential in South Africa. In this way we intend to provide the crucial context for policy and academic studies of the land issue in South Africa. Furthermore, we will undertake our study in such a way that comparison can be made to Zimbabwe and Kenya where the land issue has been such a critical component of the post-colonial development process. Theoretically our work is contextualised within the debates surrounding the importance of geographical endowments, institutions and policies in the development process.
