- Description: Debates about whether journalism is a “trade” and can only be learnt “on the job”, or whether journalism should even be taught at universities, are no longer fruitful or even interesting for teachers in tertiary environments. The far more important discussion around the teaching of journalism should be on the approach which focuses too exclusively on its nature as a “profession” and so ignores the critical function of journalists in the world as “interpretive communities”.

- Description: Information and Communication Technology (ICT) has made it possible to explore novel and innovative mechanisms to leap-frog socio-economic development in rural and marginalized communities. An ICT for development intervention called Siyakhula Living Lab (SLL) has been underway in Dwesa, a rural community in the Eastern Cape Prov-ince, for the past four years. The living lab methodology, which enables user-driven innovation within a multi-stakeholder relationship of aca-demia, user communities, government and private industry, has facili-tated greater integration of the Dwesa community into the digital ecolo-gy and subsequently the knowledge society. This paper introduces the SLL intervention, discusses the SLL's supporting technical infrastruc-ture and the interventions that are undertaken towards long-term sus-tainability of the project. The developed eServices are also discussed, with a view to highlighting the key characteristics that contribute to in-creased context-sensitivity, ownership, and buy-in from the community.

- Description: Recent discussions in South Africa about the role of the so-called patriotic bourgeoisie highlight the much debated question of what role elite Africans can and ought to play in the upliftment of the poor. Those supporting the notion of a patriotic bourgeoisie believe that national or racial solidarity is sufficient to allow privileged Africans to act in the interests of their poorer fellow citizens. However, a reconsideration of an older discussion of African elitehood, that of Amilcar Cabral, suggests that something more may be needed before elites can act in the interests of the poor. Cabral argues that elites need to renounce their privilege and to live and struggle alongside the poor if pro-poor societal transformation is to be achieved. While Cabral may be right that shared racial or national identity is insufficient for elite solidarity with the poor, he does not consider all the complexities that arise when elites actually try to work with and for the poor. A consideration of the experiences of a long-standing Senegalese NGO reveal some of these complexities and suggest that any attempt by African elites to engage meaningfully in the upliftment of the poor, will inevitably involve continuous and difficult negotiation between paternalism and naïve egalitarianism.

- Description: The East Cape, and in particular the Smaldeel area, is used to exemplify some of the characteristics and problems of commercial farming over a period of about three decades to serve as a backdrop for the broader theme of normalising South African agriculture. The regional economy is dominated by Port Elizabeth-Uitenhage and East London which account for most of the population and three-fourths of the Gross Geographic Product (GGP). Agriculture accounts for only 10% of GGP, but is one of the most labour intensive sectors in a region with 24% of its population unemployed. The agricultural economy of the region is very diversified, but livestock farming plays the most important part in all areas contributing 72% of gross income. The chief changes which have occured in East Cape farming, as elsewhere, have been the decline in the number of farms and increase in farm size, greater capital investment, increased specialisation and declining employment.

- Description: Pollution of the environment is becoming an increasingly serious problem. A large contributor to this is industry which generates effluent as a by-product of its production process. Two methods of controlling the pollution generated by industry are the so-called “command and control” techniques and economic incentives. In theory, economic incentives promise a more economically efficient and equitable means of pollution control. This paper sets out to ascertain whether this would hold in practice by applying environmental economic theory to the practical problem of controlling the effluent generated by one particular industry, viz the South African leather industry.

- Description: The syntheses and comparative studies of the spectral, voltammetry and spectroelectrochemical properties of new manganese phthalocyanine complexes, tetra-substituted with diethylaminoethanethio at the peripheral (complex 3a) and non-peripheral positions (complex 3b) are reported. Solution electrochemistry of complex 3a showed quasi-reversible metal-based (MnIIIPc−2/MnIIPc−2, E1/2 = −0.07 V vs. Ag|AgCl) and ring-based (MnIIPc−2/MnIIPc−3, E1/2 = −0.78 V vs. Ag|AgCl) reductions, but no ring-based oxidation. However, complex 3b showed weak irreversible ring-oxidation signal (Ep = +0.86 vs. Ag|AgCl). Reversible metal-based (MnIIIPc−2/MnIIPc−2, E1/2 = −0.04 V vs. Ag|AgCl) and ring-based (MnIIPc−2/MnIIPc−3, E1/2 = −0.68 V vs. Ag|AgCl) reductions were also observed for complex 3b. Spectroelectrochemistry was used to confirm these processes. Reduction process involving the metal (MnIIIPc−2/MnIIPc−2) was associated with the formation of manganese μ-oxo complex in complex 3a.

- Description: Molecular films of manganese phthalocyanine (MnPc) complexes, tetra-substituted with 2-diethylaminoethanethio at the peripheral (Mn(OAc)-β-TDEAETPc, 1) and non-peripheral (Mn(OAc)-α-TDEAETPc, 2) positions were formed on glassy carbon electrode by electropolymerization and electrodeposition respectively. Atomic force microscopy images confirmed the presence of the films and revealed significant morphological differences. The films exhibited an electrocatalytic activity towards the oxidation of the insecticide, bendiocarb. Hydrodynamic technique, using rotating disc electrode voltammetry, was used to investigate the kinetics of electro-oxidation of the insecticide. Morphological differences of the films significantly influenced kinetic parameters. Values of Tafel slopes, obtained from Tafel plots, suggested that catalysis of bendiocarb occurred via outer sphere mechanism.

- Description: Phonolites of Palaeogene age occur at two different localities in central Namibia, occurring as clusters of eroded monogenetic lava domes. Six phonolites at Aris collectively exhibit a narrow compositional range and represent a single magma system of highly evolved phonolite with high concentrations of Na2O, Rb, Th, Zr, Zn, Pb, and REE and very low abundances of MgO, P2O5, Sr and Ba. No mafic rocks are associated with the Aris phonolites and their ultimate petrogenetic origin remains obscure. The more abundant Staalhart phonolites exhibit more variable but scattered compositional variation consistent with fractional crystallization dominated by sanidine (and nepheline) and pyroxene. The behaviour of REE is decoupled from Zr, Nb, and Th in this suite indicating a controlling role for minor phases in their evolution. The least evolved phonolites have initial 87Sr/86Sr 0.7043, which is identical to a small occurrence of associated plagioclase-bearing nephelinite indicating a possible petrogenetic link.

- Description: This article deliberates the possibilities for Regional Centres of Expertise (RCEs) to become ‘experiments’ in social learning. The purpose of the article is to advance the broader research agenda of RCEs through reflection on the empirical research agenda of one RCE, Makana RCE in South Africa. As such it opens questions on how we might see RCE’s as morphogenic social learning processes (i.e., processes of social change). It provides an oversight of the key issues, educational foci and developing areas of engagement in the Makana RCE. These provide an overview of the ‘starting points’ for social learning in the Makana RCE. A model of social learning is also provided which seeks to engage the ecocultural nature of sustainability practices in the Makana RCE.

As such it opens questions on how we might see RCE’s as morphogenic social learning processes (i.e., processes of social change). It provides an oversight of the key issues, educational foci and developing areas of engagement in the Makana RCE. These provide an overview of the ‘starting points’ for social learning in the Makana RCE. A model of social learning is also provided which seeks to engage the ecocultural nature of sustainability practices in the Makana RCE.

- Description: In Black Skin, White Masks Frantz Fanon discusses the neurotic condition that typifies the oppressed black subject, their ‘psychoexistential complex’. He argues that this neurotic condition is closely related to another, the ‘psychoexistential complex’ of the white oppressor. Both of these complexes sustain and are sustained by social and economic injustice. But Fanon does not delve in detail into the nature of this second neurosis, for he was primarily interested in discussing this neurosis only insofar as it helps him understand the first. My aim in this paper is to provide an account of the white neurosis, and why it should be understood literally as a neurotic condition. Typical, white oppressors, not solely those who are militantly committed to oppressing others, are alienated from the world and from themselves, making their behaviour seem like that of soulless dolls, to use J.M. Coetzee’s image from Age of Iron.

- Description: Book review: I strongly recommend The Pursuit of Unhappiness to anyone interested in knowing where debates on happiness and well-being are at, and for a rich, intricately argued and thought-provoking engagement with an impressive array of literature in both philosophy and psychology. This book provides the most comprehensive and sophisticated interdisciplinary cutting-edge analysis of the ‘mongrel’ concepts of happiness and well-being that I know of, and it should be considered a central text for anyone interested in research on happiness. There will be plenty of material to disagree with, but any serious attempt to make progress in the debates on happiness will have to engage with The Pursuit of Unhappiness.

- Description: The importance of the middlemen of marketing was recently high-lighted with the publication of a thirty item 'food basket' for South Africa. While the producer's share of the foodbasket is usually of chief interest to the farmers of our country and often to agricultural economists, the field of traditional agricultural marketing takes in the whole area from farm gate to consumer's table.

- Description: In this article we explore the possible contribution of the Web in promot-ing the use and status of African languages. Participation in sharing and producing knowledge through the Web can play a key role in the eco-nomic, social and educational development of Africa. While physical ac-cess to information is hampered by lack of infrastructure and connectivi-ty, epistemological access is hampered by the use of English. Re-sources in African languages are available. Until the amount of Web content and the number of users reach critical mass, these resources play a symbolic rather than an instrumental role in promoting African lan-guages. The use of electronic resources available on the Web could contribute to cutting the printing and transport cost of paper material, es-pecially in multilingual settings where many languages would have to be represented. Another practical way in which the Web can promote the development of African languages is to promote communication among their speakers. This is already showing its potential by allowing experts from various disciplines to work collaboratively on the development of new indigenous terminology through mailing lists and chat rooms. On a larger scale, the Web can play a unifying function among speakers of different varieties of the same African language.

- Description: Environmental Education involves a variety of teaching and learning processes which are diversely situated in a range of social and educational contexts. The diversity of scope is an interesting 'contour' of a field like environmental education. Contemporary environmental sciences and complexity studies draw our attention to an ever-changing world and to increasingly complex social-ecological issues, patterns and risks that require our attention. These too influence the scope of environmental education teaching and learning processes. This edition of the Southern African Journal of Environmental Education provides a window through which we may see some of the scope of environmental education activities, research questions, learning and teaching settings, and educational activity. It provides insight into the range of research methodologies that are being deployed to investigate the educational processes that are needed for re-orientation towards sustainability, equity, adaptability and transformation at the people-environment interface.
