Stephanus Le Roux Marais (1896−1979) lived in Graaff-Reinet, South Africa, for nearly a quarter of a century. He taught music at the local secondary school, composed most of his extended output of Afrikaans art songs, and painted a number of small landscapes in the garden of his small house, nestled in the bend of the Sunday’s River. Marais’s music earned him a position of cultural significance in the decades of Afrikaner dominance of South Africa. His best-known songs (“Heimwee,” “Kom dans, Klaradyn,” and “Oktobermaand”) earned him the local appellation of “the Afrikaans Schubert” and were famously sung all over the world by the soprano Mimi Coertse. The role his ouevre played in the construction of a so-called European culture in Africa is uncontested. Yet surprisingly little attention has been paid to the rich evocations of landscape encountered in Marais’s work. Contextualized by a selection of Marais’s paintings, this article glosses the index of landscape in this body of cultural production. The prevalence of landscape in Marais’s work and the range of its expression contribute novel perspectives to understanding colonial constructions of the twentieth-century South African landscape. Like the vast, empty, and ancient landscape of the Karoo, where Marais lived during the last decades of his life, his music assumes specificity not through efforts to prioritize individual expression, but through the distinct absence of such efforts. Listening for landscape in Marais’s songs, one encounters the embrace of generic musical conventions as a condition for the construction of a particular national identity. Colonial white landscape, Marais’s work seems to suggest, is deprived of a compelling musical aesthetic by its very embrace and desired possession of that landscape.

There is growing interest in the development of measures and indexes of youth wellbeing. However, there has been a limited discussion on indicators to measure and select them. This paper reports on the results of a qualitative study on the selection of indicators to measure the wellbeing of young people in South Africa, and reflects on the relevance of the content of their values in choosing indicators for measuring their wellbeing. The data used in this analysis is based on telephone (9) and email (6) interviews conducted with 15 young people (male=5, female=10) aged 22 to 32 from five South African cities during July 2010. In the interviews, participants were asked to identify five issues they considered important to their lives, after which they were asked to rank them in order of importance. The issues indicated by the participants are described and discussed in six dimensions: economic, relationships, spiritual and health, education, time use and material. The indicators developed from this study are discussed in terms of their relevance for use in a measure of youth wellbeing in South Africa.

Abstract. In South Africa, the invasion of riparian forests by alien trees has the potential to affect the country's limited water resources. Tree water-use measurements have therefore become an important component of recent hydrological studies. It is difficult for South African government initiatives, such as the Working for Water (WfW) alien clearing program, to justify alien tree removal and implement rehabilitation unless hydrological benefits are known. Consequently, water use within a riparian forest along the Buffeljags River in the Western Cape of South Africa was monitored over a 3-year period. The site consisted of an indigenous stand of Western Cape afrotemperate forest adjacent to a large stand of introduced Acacia mearnsii. The heat ratio method of the heat pulse velocity sap flow technique was used to measure the sap flow of a selection of indigenous species in the indigenous stand, a selection of A. mearnsii trees in the alien stand and two clusters of indigenous species within the alien stand. The indigenous trees in the alien stand at Buffeljags River showed significant intraspecific differences in the daily sap flow rates varying from 15 to 32 L day−1 in summer (sap flow being directly proportional to tree size). In winter (June), this was reduced to only 7 L day−1 when limited energy was available to drive the transpiration process. The water use in the A. mearnsii trees showed peaks in transpiration during the months of March 2012, September 2012 and February 2013. These periods had high average temperatures, rainfall and high daily vapor pressure deficits (VPDs – average of 1.26 kPa). The average daily sap flow ranged from 25 to 35 L in summer and approximately 10 L in the winter. The combined accumulated daily sap flow per year for the three Vepris lanceolata and three A. mearnsii trees was 5700 and 9200 L, respectively, clearly demonstrating the higher water use of the introduced Acacia trees during the winter months. After spatially upscaling the findings, it was concluded that, annually, the alien stand used nearly 6 times more water per unit area than the indigenous stand (585 mm a−1 compared to 101 mm a−1). This finding indicates that there would be a gain in groundwater recharge and/or streamflow if the alien species are removed from riparian forests and rehabilitated back to their natural state.

The intranet is a common feature in many organizations. With the increasing use of a technology infrastructure in organizations, there is a continued challenge for employees in an organization to contribute their knowledge willingly and to make use of knowledge sharing with other employees. Intranets are well-suited for use as a strategic tool in knowledge sharing due to their ability to support the distribution, connectivity and publishing of data and information. Intranets should be seen as integral to an organization’s knowledge management strategy and should be tailored to suit and enhance an organization’s knowledge-sharing activities. The question arises: To what extent does an organization’s existing intranet facilitate knowledge sharing? From a practitioner-based inquiry perspective, this question was explored by the selection of a large organization – eThekwini Municipality, Durban, South Africa – as the field of application. Derived from a mixed methodology approach, the results of a survey are presented. It is suggested that encouragement be given for more practitioner-based inquiry research.

In view of the dire state of literacy levels in South Africa and the fact that few literacy programmes provide research reports to evaluate best practices and effectivity, this article reports on the evaluation of a literacy project. The project, inspired by two children, is referred to as the Zoë-reading aloud project and targeted children in and around Upington in the Northern Cape, South Africa. The project was set up according to acknowledged reading promotion principles and it was structured to collect detailed data. Qualitative and quantitative data collection methods were used and a selection of methods provided reliability. The findings of the analysis of a collection of data for a period of 15 months revealed the best practices of the project. It highlights, for example, the need for financial assistance and challenges the concept of family literacy in low-literate and poor communities.

In South Africa, the school textbook remains a powerful source of content knowledge to both teachers and learners. Such knowledge is often engaged uncritically by textbook users. As such, the worldviews and value systems in the knowledge selected for consumption remain embedded and are likely to do powerful ideological work. In this article, we present an account of the ideological orientations of knowledge in a corpus of school economics textbooks. We engage the tenets of critical discourse analysis to examine the representations of the construct “poverty” as a taught topic in the Further Education and Training Economics curriculum. Using Thompson’s legitimation as a strategy and form-function analysis as specific analytical tools, we unearth the subtext of curriculum content in a selection of Grade 12 Economics textbooks. The study reveals how power and domination are normalised through a strategy of economic legitimation, thereby offering a “legitimate” rationale for the existence of poverty in the world. The article concludes with implications for curriculum and a humanising pedagogy, and a call for embracing critical knowledge on poverty in the South African curriculum.

Whereas photography of insects at rest is used for a wide variety of purposes, including illustrating publications and aiding their identification, photography of insects in flight is more challenging and little practiced. This paper describes a system that uses a digital single-lens-reflex camera combined with commercial-level flashes (with electronic power settings to give very short exposures) and simple electronics in a rig that can be used to capture high quality images of night-flying insects. With such a rig, hundreds of images of free flying Trichoptera have been obtained. Preliminary observations of night-flying Athripsodes bergensis (Leptoceridae) indicate that this system could be used for studying the mechanics of flight, wing beat frequency, aerodynamics, flying speed, aerial activity, and behavioural ecology of night-flying insects in their natural environment.      This paper briefly describes the technique as applied at a site on the banks of the Groot River in the southern Cape region of South Africa between October 2008 and April 2009 and presents a selection of the images obtained.
