- Description: Al/Cr atomic ratios of coexisting spinellids and ortho- and clinopyroxenes show a pattern of sympathetic variation that persists through ultramafic rocks of layered mafic complexes of upper-crustal type, Alpine complexes, and the nodules found in kimberlites and alkaline basalts. Simple expressions are empirically derived to link (Al/Cr) orthopyroxene and (Al/Cr)spinel ratios in putatively equilibrated rocks. Equivalence of spinel compositions in shallow layered complexes and kimberlite nodules of deep-seated origin negates direct crystallochemical control of Al/Cr ratios of spinels by pressure.

- Description: The election promise of the majority party in the new South African government was to redistribute 30% of the agricultural land in the hands of Whites within a period of 5 years. Transfers of land in the Eastern Cape Province are examined as a case study. While 60% of the total number of Eastern Cape farms changed hands over 5 years, these constituted only 19% of the surface area. A large proportion of rural transfers were small (less than 5 hectares) peri-urban properties which cannot all be considered as viable farming units. At average prices about R1 to R2 billion would be required to establish new farmers on land with the necessary livestock, machinery and equipment. Resource poor new entrants would need a major state contribution to make initial entry and subsequent survival feasible. To achieve their goal through market transfers the government would need to either substantially lengthen its time horizon or lower its target.

- Description: preprint , We need to develop a much more refined and specific understanding of what is meant when people refer to language is a ‘resource’. If something can accurately be described as a resource, then by its very nature it carries with it or attracts, at least in potential, the social motivation associated with the utilization, development or exploitation of that resource. This is strikingly true where language is the resource in question, because language is so intimately bound up with human activity. Where it exists, such social motivation can be augmented and supported so as to realize the ends of language policy. Contrastingly, where it is seen that social motivation informing a particular language situation is at odds with the intent of language policy, then either implementation must retreat and move to other arenas, other points of influence, where intervention can be more effective, or those charged with implementation must resign themselves to costly and messy efforts to force unwanted change through legal authority.

- Description: Phonolites of Tertiary age occur as eroded tholoids, lava flows, ignimbrites, and coulees in the Klinghardt Mountains of southern Namibia. Sixty samples have been analyzed for major and trace elements and fourteen of these for 87SR 86SR. The phonolites lie close to the low-pressure cotectics in Q-Ne-Ks, in keeping with their petrography which indicates that most samples have phenocrysts of both nepheline and sanidine. Na has been variably lost from the rocks during crystallization and devitrification/alteration of hypocrystalline specimens.

According to South African film director Feizel Mamdoo, there are particular moments in history that are defined by photographic, celluloid, or television images, such as the world famous photograph of the Saigon girl, naked and burning from napalm (Worsdale 1998; see also Richards 2001). He argues that the iconic photograph by Sam Nzima depicting Hector Pieterson being carried in the arms of Mbuyisa Makhubu, with his distraught sister Antionette1 running alongside, is comparable in the way that “it marks history, both social and personal” (Worsdale 1998).

- Description: This paper attempts to address the ambiguity so frequently highlighted in South Africa's post-apartheid foreign policy. Three central arguments are put forward. Firstly, it is argued that traditional accounts of South Africa's foreign policy, utilizing rationalist or ‘mainstream’ theories of International Relations, are insufficient in themselves to explain the complexities inherent in the country's foreign policy. In this regard, constructivist IR theory offers several key insights into studies of South Africa's foreign policy. Secondly, although it is argued that constructivism, particularly its focus on identity, is crucial to understanding South African foreign policy, it alone cannot sufficiently explain its reception or results on the world stage. Finally, it is argued that in order to fully appreciate both the nature and effects of South Africa's foreign policy, a mixed focus, incorporating insights from both constructivist and materialist-based theories of IR, is necessary.

This evolving characteristic exhibited by the learners across South Africa must generate a serious reflection of education and training methodologies. Historically, education structures have been slow to embrace the changes that are imperative if the products of the process are to be adequately prepared for the future that faces them. One of the most telling realities of the modern era, or the planetary phase as it is now being tagged, is rapid change. The question that all educators need to ask is 'how is my pedagogic approach evolving'?.

- Description: Despite the debate about whether arts consumers are also sports consumers, many countries have used cultural events to leverage further tourism spending from sports events, the most famous example being the cultural Olympics. This paper reports the findings of research conducted at the 2010 South African National Arts Festival, which was specifically timed to coincide with SoccerWorld Cup matches being played in a nearby city. Of the 600 interviews conducted with Festival-goers, only 23% reported also attending World Cup soccer matches. Regression analysis revealed that, while there is some overlap between arts and sports attendees, their demographics and consumption habits are significantly different. However, consumption outside of major events showed somewhat more overlap. This suggests that staging cultural events at the same time as major sporting events is not an ideal strategy, since they tend to compete with, rather than complement, each other.

- Description: South Africans today live not only with the memory of the racial injustices of the past, but also with present injustices that are a consequence of that past. How should white South Africans live with these past and present injustices? On recognition of the racial injustices of the past and of the continuation of forms of white privilege today, involvement in ongoing anti-racist struggles seems to be an appropriate way for white South Africans to respond to past and present injustices. However, some discussions of the way in which white privilege operates and is perpetuated in post-segregationist societies suggest the need for caution with regard to white involvement in anti-racist struggles, arguing that some of the ways in which white people involve themselves in apparently anti-racist work actually result in the perpetuation rather than the erosion of white privilege. This article explores concerns about the intractability of white privilege while also ultimately defending the appropriateness of white involvement in anti-racist struggles.

- Description: This article reports on regularities observed in learners’ preconceptions of reflective symmetry. Literature suggests that the very existence of such regularities indicates a gap between what learners know and what they need to know. Such a gap inhibits further understanding and application, and hence needed to be investigated. A total of 235 Grade 11 learners, from 13 high schools that participate in the First Rand Foundation-funded Mathematics Education project in the Eastern Cape, responded to a task on reflective symmetry. Our framework for analysing the responses was based on the taxonomy of structure of the observed learning outcome. The results indicated that 85% of learner responses reflect a motion understanding of reflections, where learners considered geometric figures as physical motions on top of the plane. While this understanding is useful in some cases, it is not an essential aspect of mapping understanding, which is critical for application in function notations and other analytical geometry contexts. We suggest that if this gap is to be closed, learners need to construct these reflections physically so that they may think of reflections beyond motion.

Could a regulated market approach for rhinoceros horns work in South Africa? Some practical issues and concerns

- Description: Publisher version , One of the proposals for fighting rhinoceros poaching is to legalise the trade in rhino horn and adopt a regulated market approach (RMA), which would require a vote at the 2016 CITES meeting in order to overturn the ban on the trade in rhino horn. The legal trade in rhino horn would enable the auctioning of stockpiles of horn and encourage captive breeding programmes. The aim of increasing the supply of horn is to reduce incentives to poach by driving down the price. This paper uses a conceptual/theoretical approach to consider the practical implications of the adoption of an RMA, drawing on demand, supply and production theory. The intention is explicitly to set out some practical concerns and issues that seem to have been underplayed or neglected in most published economic discourse on the subject. To secure a stockpile for some species needs biological success in captive breeding programs (CBPs) but this varies across species and habitats. Rhinoceros herds in a CBP would need relatively spatially extensive terrain and costly permanent security measures, and only appear feasible for the less aggressive “white” rhino. Thus, market price would actually need to be sustained at a high level to cover the start-up and security costs of such a programme that are unlikely to fall significantly. This is a double-edged sword in that the persistent high price of rhino horn provides an incentive for continued poaching activities. Supplementary policy measures that differentiate among consumer groups may also prove necessary.

- Description: Economic indicators, like gross domestic product per capita, are commonly used as indicators of welfare. However, they have a very limited and narrow scope, excluding many potentially important welfare determinants, such as health, relative income and religion – not surprising since they were not designed to fill this role. As a result, there is growing acceptance, and use of, subjective measures of well-being (called ‘happiness’ or ‘life satisfaction’, often used interchangeably) both worldwide and in South Africa. Happiness economics does not propose to replace income-based measures of well-being, but rather attempts to complement them with broader measures, which can be important in making policy decisions that optimise societal welfare. This paper tests for differences in subjective well-being between race groups in South Africa, and investigates the determinants of self-rated life satisfaction for each group. Using the 2008 National Income Dynamics Study data, descriptive methods (analysis of variance) and an ordered probit model are applied. Results indicate that reported life satisfaction differs substantially among race groups, with black South Africans being the least satisfied group despite changes since the advent of democracy in 1994. Higher levels of educational attainment increased satisfaction for the whole sample, and women (particularly black women) are generally less satisfied than men. As found in many other studies, unemployed people have lower levels of life satisfaction than the employed, even when controlling for income and relative income. The determinants of life satisfaction are also different for each race group: white South Africans attach greater importance to physical health, whereas employment status and absolute income matter greatly for black people. For coloured people and black people, positional status (as measured by relative income) is an important determinant of well-being, with religious involvement contributing significantly to the well-being of Indian people.

Cosmological efficacy and the politics of Sacred Place: Soli Rainmaking in contemporary Zambia

My term “festivalization” registers the formalization of Zambian performances such as rituals, harvest festivals, inaugurations, and initiations as annual festival events, but does not imply a pejorative attitude towards cultural change and so-called inauthenticity, as the words “folklorization” or “retraditionalization” seem to do.

- Description: Regional and temporal variations in the diets of rocky shore suspension-feeders (the volcano barnacle Tetraclita serrata, the brown mussel Perna perna and the reef-building polychaete Gunnarea gaimardi) were assessed using fatty acid profiling. Specimens were collected up-current and down-current of a river mouth in 2 coastal regions ~50 km apart along southeastern South Africa during March and July of 2009. One of the rivers represents a marine-dominated system, and the other a freshwater-dominated system. Our aims were to assess any dietary differences among the 3 suspension-feeders, spatial changes in diet within each species (at regional and local scales—50 and 15 km, respectively), and temporal changes in diet within each species.
