- Description: While there is a fair amount of work on determinants of demand for the live performing arts, results have often been contradictory with little explanatory power. This may be because of the difficulty in describing the attributes of a performance, particularly in terms of its quality, and the heterogeneity of consumer preferences. This article uses conjoint analysis, also called choice experiments, to investigate the impact of the attributes of live theatre performances on demand, using data collected from 483 randomly chosen attenders at live theatre performances at the 2008 South African National Arts Festival. Attributes include the type of cast (professional, semi-professional or amateur), reputation of the producer/director, the context or setting, production type and ticket price of the show. Results largely support the a priori expectations based on the results of other demand studies. For example, it is found that the age of consumers affects the type of show chosen, that utility and willingness to pay increase for shows with professional and semi-professional casts and that 93% of the potential audience prefer shows with a South African context. It is concluded that the method could prove useful to both event organisers and policy makers, especially where the goal is to broaden access to the arts.

- Description: Private land conservation areas (PLCAs) have become critical for achieving global conservation goals, but we lack understanding of how and when these areas respond to global pressures and opportunities. In southern Africa, where many PLCAs rely on trophy hunting as an income‐generating strategy, a potential ban on trophy hunting locally or abroad holds unknown consequences for the future conservation of these lands. In this study, we investigate the consequences of a potential trophy hunting ban in PLCAs in two biodiversity hotspots in South Africa's Eastern and Western Cape provinces. We used semistructured interviews with PLCA managers and owners to elicit perceived impacts of an internationally imposed trophy hunting ban on conservation activities in PLCAs, and to probe alternative viable land uses.

- Description: Today, many elements of the tradition have been discarded or adapted; nevertheless, the concept of singing praises still retains an identifiable character which is based on past tradition. In this tradition, the imbongi' s relationship with his audience and the function of his izibongo (poetry) within his society are of utmost importance. Any analysis of this communitarian art form will therefore have to take into account the context of the performance, the nature of the audience, and the role of the imbongi in a society which continues to be subject to socio-cultural and political pressures of unused intensity. My intention in this article is to provide a case study of Bongani Sitole, a contemporary imbongi, in order to instance some of the ways in which the tradition has adapted. During the course of the discussion mention will also be made of other iimbongi.

- Description: Wetland hydrological health and the provision of indirect ecosystem services in the eMthonjeni–Fairview Spring Wetland, Grahamstown, South Africa, were assessed in 2008, using the newly developed wetland assessment tools WET-Health and WET-EcoServices. Variation in health and ecosystem services were assessed over time, based on aerial photograph interpretation and the use of the score sheets in these assessment tools. Hydrological health and indirect ecosystem services of the wetland have been altered since 1949, due to human activities both in the catchment and the wetland. The most significant human intervention on the wetland's hydrological health was the result of road construction and invasion by alien plants. Water use by local residents had an unmeasurable effect on hydrological health. Wetland health is related to the provision of wetland ecosystem services, and cumulative impacts in the catchment and wetland have reduced the provision of many indirect wetland ecosystem services.

The result has been that the novel acquired a rather odd penumbra of interpretation, ranging from the naïve to the dismissive or reductive.

Look up ‘Peteni’ in the Companion to South African English Literature (1986) and you will be told that Hill of Fools is “loosely based on the story of Romeo and Juliet” (155). Scan the first newspaper reviews (see “The Early Reception of Hill of Fools” in this volume) and it is noticeable that a great many journalists focus on the Shakespeare connection as a means of introducing the book to their readers. One of the publisher’s readers, Henry Chakava, urged before publication that once all references to tribe or tribalism had been excised “the result will be a Romeo and Juliet type story much more superior to Weep Not Child.” The author himself reportedly described the book as “a black Romeo and Juliet drama” (Tribune Reporter 1988). And, indeed, some kind of parallel is patent to anyone who reads Hill of Fools with Shakespeare’s play in mind.

- Description: The red steenbras Petrus rupestris is endemic to South Africa, occurring from False Bay in the Western Cape Province to St Lucia in the province of KwaZulu-Natal. This species, the largest member of the family Sparidae, has undergone a substantial stock decline as a result of overfishing and is considered to be collapsed. Various aspects of its life history, including high residency, predictable migrations, late maturity and longevity, have made it vulnerable to overexploitation. This study analysed the diversity and genetic structure of red steenbras across seven sampling regions, using mitochondrial (control region) and nuclear (S7 intron 1) DNA markers.

- Description: publisher version , The potential for national pride to take on shades of both the authentic and the hubristic is reflected in the International Social Survey Program's (ISSP) use of two different multi-item measures of national pride, a general and a domain-specific one. In contrast, domain-specific national pride is characterized as 'not overtly nationalistic, imperialistic, nor chauvinistic' and is expressed as positive feelings towards national accomplishments in a range of domains including arts, science and sport. Most scholars who take an interest in the impact of sport mega-events acknowledge that national pride is related to concepts such as patriotism and nationalism whose meanings are difficult to disentangle. The South African Social Attitudes Survey (SASAS), which has tracked the attitudes of South African adults around the 2010 World Cup, has confirmed this idea. The longitudinal SASAS study found that subsequent to the event, there was an enormous upswing in the belief that the World Cup had a positive impact on social cohesion.

- Description: Urban green infrastructure provides ecosystem services that are essential to human wellbeing. A dearth of national-scale assessments in the Global South has precluded the ability to explore how political regimes, such as the forced racial segregation in South Africa during and after Apartheid, have influenced the extent of and access to green infrastructure over time. We investigate whether there are disparities in green infrastructure distributions across race and income geographies in urban South Africa. Using open-source satellite imagery and geographic information, along with national census statistics, we find that public and private green infrastructure is more abundant, accessible, greener and more treed in high-income relative to low-income areas, and in areas where previously advantaged racial groups (i.e. White citizens) reside.

- Description: Wild edible fruits (WEFs) are important non-timber forest products (NTFP) that are commonly grouped with other wild foods or NTFPs in general. We hypothesize that WEFs, other wild foods, and non-food NTFPs contribute in different ways to household economies. Using data collected through a survey of 503 households in South Africa, we describe patterns of use of WEFs across socioeconomic and geographical gradients and compare them to the patterns of use of other wild foods and non-food NTFPs. WEFs were used by one-fifth of all sampled households, independent of economic and urbanisation gradients and were grown in or collected mostly from surrounding areas. More households, usually in rural areas, used other wild foods and non-food NTFPs, which were often purchased from other collectors.

- Description: Wild edible fruits (WEFs) are important non-timber forest products (NTFP) that are commonly grouped with other wild foods or NTFPs in general. We hypothesize that WEFs, other wild foods, and non-food NTFPs contribute in different ways to household economies. Using data collected through a survey of 503 households in South Africa, we describe patterns of use of WEFs across socioeconomic and geographical gradients and compare them to the patterns of use of other wild foods and non-food NTFPs. WEFs were used by one-fifth of all sampled households, independent of economic and urbanisation gradients and were grown in or collected mostly from surrounding areas. More households, usually in rural areas, used other wild foods and non-food NTFPs, which were often purchased from other collectors.

- Description: Oral traditions and oral literature have long contributed to human communication, yet the advent of arguably the most influential technology—the written word—altered the course of creative ability. Despite its potential and scope, the development of the written word resulted in an insidious dichotomy. As the written word evolved, the oral word became devalued and pushed to the fringes of society. One of the unfortunate consequences of this transition to writing has been a focus on the systems and conventions of orality and oral tradition. Although of importance, a more appropriate focus would be on ways of supporting and maintaining the oral word, and its innate value to human society, in the face of rampant technological development. Yet it is ironic that technology is also helping to create a fecund environment for the rebirth of orality. This paper offers an overview of the debate about the relationship between oral literature, the written word and technology, and suggests that the term technauriture may offer a suitable encompassing paradigm for further engagement with the oral word and its application to modern society. We discuss the late Bongani Sitole, a poet whose oral works were transformed into public and educational resources through the application of technology, and we consider the utility of the term technauriture for describing the relationship between orality, literature and technology.

- Description: Achieving food security in a ‘perfect storm’ scenario is a grand challenge for society. Climate change and an expanding global population act in concert to make global food security even more complex and demanding. As achieving food security and the millennium development goal (MDG) to eradicate hunger influences the attainment of other MDGs, it is imperative that we offer solutions which are complementary and do not oppose one another. Sustainable intensification of agriculture has been proposed as a way to address hunger while also minimizing further environmental impact. However, the desire to raise productivity and yields has historically led to a degraded environment, reduced biodiversity and a reduction in ecosystem services (ES), with the greatest impacts affecting the poor. This paper proposes that the ES framework coupled with a policy response framework, for example Driver-Pressure-State-Impact-Response (DPSIR), can allow food security to be delivered alongside healthy ecosystems, which provide many other valuable services to humankind. Too often, agro-ecosystems have been considered as separate from other natural ecosystems and insufficient attention has been paid to the way in which services can flow to and from the agro-ecosystem to surrounding ecosystems. Highlighting recent research in a large multi-disciplinary project (ASSETS), we illustrate the ES approach to food security using a case study from the Zomba district of Malawi.

- Description: Complex modifications of angiosperm flowers often function for precise pollen placement on pollinators and to promote cross-pollination. We explore the functional significance of the unusually elaborate morphology of Gloriosa superba flowers, which are divided into one hermaphrodite meranthium and five male meranthia (functional pollination units of a single flower). We used controlled pollination experiments, floral measurements, pollen load analyses and visitor observations in four populations of G. superba in South Africa to determine the breeding system, mechanism of pollination and role of flower in the promotion of cross-pollination.

- Description: Rotational structures have been measured using the Jurogam II and GAMMASPHERE arrays at low spin following the 155Gd(α,2n)157Dy and 148Nd(12C,5n)155Dy reactions at 25 and 65 MeV, respectively. We report high-K bands, which are conjectured to be the first candidates of a Kπ=2+γ vibrational band, built on the [505]11/2− neutron orbital, in both odd-A155,157Dy isotopes. The coupling of the first excited K=0+ states or the so-called β vibrational bands at 661 and 676 keV in 154Dy and 156Dy to the [505]11/2− orbital, to produce a Kπ=11/2− band, was not observed in both 155Dy and 157Dy, respectively. The implication of these findings on the interpretation of the first excited 0+ states in the core nuclei 154Dy and 156Dy are also discussed.

- Description: The fact that not all claims on the central government enjoy equal status in the eyes of policymakers has been vividly illustrated by the recent experience of South African universities. Indeed, it is not alarmist to describe the present financial position of these institutions as approaching a state of crisis. Consequently, there is an urgent need for members of the university community in this country to re-examine the whole question of university finance. The present paper attempts to address precisely this issue, and proposes a radical alternative to the current method of finance. A caveat must be added at the outset. First, the analysis will be restricted to universities per se although it could be extended mutatis mutandis to include some other institutions within the tertiary education sector, and secondly, the primary focus will fall on developing a broad framework rather than on a detailed examination of the minutiae of university funding. Section I evaluates the case for public intervention in the provision of university education, and the various alternative approaches to the problem of university finance are outlined in Section II. A specific proposal for the financing of university education is set out in Section III, together with a rebuttal of some of the more important objections to the scheme. The paper concludes with an overview of the central arguments in Section IV. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: Fibronectin is an extracellular matrix glycoprotein with key roles in cell adhesion and migration. Hsp90 binds directly to fibronectin and Hsp90 depletion regulates fibronectin matrix stability. Where inhibition of Hsp90 with a C-terminal inhibitor, novobiocin, reduced the fibronectin matrix, treatment with an N-terminal inhibitor, geldanamycin, increased fibronectin levels. Geldanamycin treatment induced a stress response and a strong dose and time dependent increase in fibronectin mRNA via activation of the fibronectin promoter. Three putative heat shock elements (HSEs) were identified in the fibronectin promoter. Loss of two of these HSEs reduced both basal and geldanamycin-induced promoter activity, as did inhibition of the stress-responsive transcription factor HSF1. Binding of HSF1 to one of the putative HSE was confirmed by ChIP under basal conditions, and occupancy shown to increase with geldanamycin treatment. These data support the hypothesis that fibronectin is stress-responsive and a functional HSF1 target gene. COLA42 and LAMB3 mRNA levels were also increased with geldanamycin indicating that regulation of extracellular matrix (ECM) genes by HSF1 may be a wider phenomenon. Taken together, these data have implications for our understanding of ECM dynamics in stress-related diseases in which HSF1 is activated, and where the clinical application of N-terminal Hsp90 inhibitors is intended.
