- Description: Gender is an all-pervasive and extremely influential construct in the lives of individuals (Taylor, 2003). In children’s literature, we find a reflection of the attitudes towards gender prevalent in a given society at a particular time (Peterson and Lach, 1990). Therefore the study of how gender is represented in children’s literature can make a useful contribution to our understanding of how choices in language use support particular discourses, ‘broad constitutive systems of meaning’ (Sunderland, 2004: 6) or ‘ways of seeing the world’ (op cit: 28). These representations in turn perpetuate prevailing gendered power relations in that society, as research into children’s literature has shown (Thompson and Sealey, 2007). Corpus Linguistics offers a degree of objectivity and efficiency not possible in manual ideological analysis, as well as a set of tools particularly useful for the lexical analysis of considerable quantities of text. In this chapter, I report on my analysis of gendered discourses in the Harry Potter series by J. K. Rowling, focussing on patterns around grammatical agency in the books.

- Description: Historically, biological control efforts against aquatic plants in South Africa have focused on floating species, and as a result, there has been a dearth of research into the invasion and control of submerged macrophytes. With numerous submerged invasive species already established in South Africa, thriving horticultural and aquarium industries, nutrient-rich water systems, and a limited knowledge of the drivers of invasions of submerged macrophytes, South Africa is highly vulnerable to a second phase of aquatic plant problems. Experience gained in the U.S.A. on biological control against submerged weeds, such as hydrilla, Hydrilla verticillata (L.f.) Royle (Hydrocharitaceae) and spiked / Eurasian watermilfoil, Myriophyllum spicatum L. (Haloragaceae), have provided South African researchers with the necessary foundation to initiate programmes against these weeds. Research in South Africa is currently focused on pre-release studies on the biological control of H. verticillata, using an undescribed fly, Hydrellia sp. (Diptera: Ephydridae) and a weevil, Bagous hydrillae O'Brien (Coleoptera: Curculionidae); and on M. spicatum using a North American weevil, Euhrychiopsis lecontei Dietz (Coleoptera: Curculionidae). Feasibility studies into biological control of some incipient submerged weeds are also being conducted, including Brazilian water weed, Egeria densa Planch. (Hydrocharitaceae), Canadian water weed, Elodea canadensis Mitch. (Hydrocharitaceae) and cabomba, Cabomba caroliniana A. Gray (Cabombaceae). Progress with, and potential constraints that may limit these programmes, are discussed.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 23 , The evolution of the cichlid species flock in Lake Malawi has taken place very rapidly and resulted in the proliferation of a large number of species many of which are similar to one another. This has given rise to a situation in which traditional methods of distinguishing species based on preserved specimens are often of limited value. There are many instances of different species having almost identical morphologies, of single populations of one species showing considerable morphological variation and of marked geographical intraspecific variation. Polymorphism is considered not to be as widespread as previously thought, and pronounced random intraspecific colour variation within a population is discounted. Sympatric sibling species may be distinguished by observing behavioural and habitat differences in the field, but no means has been devised for ascertaining whether morphologically and behaviourally similar allopatric forms are specifically distinct. Lack of access to fresh specimens and lack of information on distribution and habitat have resulted in numerous errors appearing in taxonomic works on Lake Malawi cichlids. Great care is needed when attempting scientific descriptions of cichlid species from the African Great Lakes, and it is suggested that such work be left to specialists with knowledge of living and fresh fish in these lakes.

- Description: Pereskia aculeata Miller (Cactaceae) is an invasive alien species in South Africa that is native in Central and South America. In South Africa, P. aculeata outcompetes native plant species leading to a reduction in biodiversity at infested sites. Herbicidal and mechanical control of the plant is ineffective and unsustainable, so biological control is considered the only potential solution. Climatic matching and genotype matching indicated that the most appropriate regions in which to collect biological control agents were Santa Catarina and Rio de Janeiro provinces in Southern Brazil. Surveys throughout the native distribution resulted in 15 natural enemy species that were associated with the plant. Field host range data, as well as previous host plant records, were used to prioritise which of the species were most likely to be suitably host specific for release in South Africa. The mode of damage was used to determine which species were most likely to be damaging and effective if released. The most promising species prioritised for further study, including host specificity and impact studies, were the stem-wilter Catorhintha schaffneri Brailovsky and Garcia (Coreidae); the stem boring species Acanthodoxus machacalis Martins and Monné (Cerambycidae), Cryptorhynchus sp. (Curculionidae) and Maracayia chlorisalis (Walker) (Crambidae) and the fruit galler Asphondylia sp. (Cecidomyiidae). By prioritising the potential biological control agents that are most likely to be host-specific and damaging, the risk of conducting host specificity testing on unsuitable or ineffective biological control agents is reduced.

- Description: The determination and remediation of three phenolic compounds bisphenol A (BPA), ortho-nitrophenol (o-NTP), parachlorophenol (PCP) in wastewater is reported. The analysis of these molecules in wastewater was done using gas chromatography (GC) × GC time-of-flight mass spectrometry while activated carbon derived from maize tassel was used as an adsorbent. During the experimental procedures, the effect of various parameters such as initial concentration, pH of sample solution, eluent volume, and sample volume on the removal efficiency with respect to the three phenolic compounds was studied. The results showed that maize tassel produced activated carbon (MTAC) cartridge packed solid-phase extraction (SPE) system was able to remove the phenolic compounds effectively (90.84–98.49 %, 80.75–97.11 %, and 78.27–97.08 % for BPA, o-NTP, and PCP, respectively) . The MTAC cartridge packed SPE sorbent performance was compared to commercially produced C18 SPE cartridges and found to be comparable. All the parameters investigated were found to have a notable influence on the adsorption efficiency of the phenolic compounds from wastewaters at different magnitudes.

- Description: Interest in postgraduate education and the supervision of postgraduate research has developed in recent years, largely as a result of the impact of the so-called ‘knowledge economy’. South Africa’s National Plan 20301 draws on globalised discourses in holding that increases in the number of graduates, particularly at doctoral level, will contribute to economic prosperity because of the potential of postgraduate education to contribute to the processes of reinvention that drive the economic system itself. Even a brief glance at the mission and vision statements of a small sample of universities shows how this idea has been taken up within the higher education sector. In the context of high levels of unemployment, the idea that a postgraduate degree can lead to better work prospects also means that students who might never have considered doing a postgraduate degree previously, have now come forward to study at this level. All this then means that academics are being called upon to take on heavier supervision loads with a diverse array of students.

- Description: For decades, most anti-capitalist and anti-imperialist movements identified radical social transformation with the capture of state power. The collapse of supposedly enabling states led recently to a crisis of left and working class politics. But this has also opened space for the rediscovery of society-centred, anti-capitalist modes of bottom-up change, labelled as ‘at a distance’ politics. These modes have registered important successes in practice, such as the Zapatistas in Mexico, and have involved strands of anarchism and syndicalism, and autonomist Marxism. This article, an introduction to a collection of papers emerging from a 2012 conference of academics and activists in South Africa, aims to help articulate an understanding of social transformation from below that has been analytically and politically side-lined not only in South Africa (and Zimbabwe), but globally. In doing so, it provides a preliminary attempt to map and create a dialogue between three major positions within the broad category of ‘at a distance’ politics.

- Description: Extant genera and subgenera of the Trogidae (Coleoptera: Scarabaeoidea) are reviewed. Contemporary classifications of this family have been based exclusively on morphological characters. The first molecular phylogeny for the family recently provided strong support for the relationships between morphologically defined genera and subgenera. On the basis of morphological, molecular and biogeographical evidence, certain taxonomic changes to the genus-level classification of the family are now proposed. The family is confirmed as consisting of two subfamilies, Omorginae Nikolajev and Troginae MacLeay, the former with two genera, Omorgus Erichson and Polynoncus Burmeister, and the latter with two genera, Trox Fabricius and Phoberus MacLeay stat. rev. Phoberus is restored to generic rank to include all Afrotropical (including Madagascan endemic) species; Afromorgus is confirmed at subgeneric rank within the genus Omorgus ; and the monotypic Madagascan genus Madagatrox syn. n. is synonymised with Phoberus. The current synonymies of Pseudotrox Robinson (with Trox ), Chesas Burmeister, Lagopelus Burmeister and Megalotrox Preudhomme de Borre (all with Omorgus ) are all accepted to avoid creating speculative synonyms before definitive phylogenetic evidence is available.

- Description: Extant genera and subgenera of the Trogidae (Coleoptera: Scarabaeoidea) are reviewed. Contemporary classifications of this family have been based exclusively on morphological characters. The first molecular phylogeny for the family recently provided strong support for the relationships between morphologically defined genera and subgenera. On the basis of morphological, molecular and biogeographical evidence, certain taxonomic changes to the genus-level classification of the family are now proposed. The family is confirmed as consisting of two subfamilies, Omorginae Nikolajev and Troginae MacLeay, the former with two genera, Omorgus Erichson and Polynoncus Burmeister, and the latter with two genera, Trox Fabricius and Phoberus MacLeay stat. rev. Phoberus is restored to generic rank to include all Afrotropical (including Madagascan endemic) species; Afromorgus is confirmed at subgeneric rank within the genus Omorgus ; and the monotypic Madagascan genus Madagatrox syn. n. is synonymised with Phoberus. The current synonymies of Pseudotrox Robinson (with Trox ), Chesas Burmeister, Lagopelus Burmeister and Megalotrox Preudhomme de Borre (all with Omorgus ) are all accepted to avoid creating speculative synonyms before definitive phylogenetic evidence is available.

- Description: This is a bold statement and a difficult one for people who regard] computers as a tool of the rich. Yes the computer is a tool or the rich. But more and more of these weird little machines are finding their way into our backyards and ghettos, into the backrooms of our community organisations and even into our classrooms. Each of these computers can do what only the rich with million rand typographic equipment could do 10 years ago . Today ordinary people can bring out media of a quality that only highly trained professionals using specialised equipment used to be able to produce. This edition of CECS NEWS is proof of this. Almost the entire newsletter was produced by High School student members of CECS trained on a 5-day camp in June. “Computers For All” is not just an empty slogan but a possible reality. We decided at the camp to devote an entire issue to just this topic: Media on Computers.

- Description: Fishes of the genus Labeo are widely distributed throughout Africa and consist of at least 80 species which comprise 16.4% of the African cyprinid ichthyofauna (Reid 1985). Most labeo species are also commercially important throughout the African continent, having contributed significantly to various fisheries. Their roe (sensu caviar) is often harvested as an additional bycatch (Skelton et al. 1991). Despite their obvious importance, the few studies that have investigated aspects of their life history have been conducted on the larger commercial species (Lowe 1952, Mulder 1973, Balon et al. 1974, Potgieter 1974, Baird 1976, Tomasson et al. 1984, van Zyl et al. 1995).

On the fast track to land degradation? A case study of the impact of the Fast Track Land Reform Programme in Kadoma District, Zimbabwe

- Description: The Fast Track Land Reform Programme is the defining instrument for Zimbabwe’s future development prospects. In the three year period from 2000 to 2002 300,000 families were resettled on 11 million hectares thus witnessing the end of the colonial division of land which had seen 15.5 million hectares still in European hands in 1980, the start of the post-colonial period. The process which displaced the commercial farm workers and farm owners was chaotic, violent and disorderly and so has been called jambanja. Subsequent legislation and government agricultural initiatives have attempted to impose, retroactively, technocratic order to the sweeping changes that have taken place. Our study shows that the dire macro-economic situation coupled with trends of HIV/AIDS prevalence means that developing sustainable land use practices is going to be a very difficult proposition. At the local scale, our case studies show that there have been multiple outcomes with low investment, very limited government support and resource extraction leading to land degradation and unsustainable farming practices. In some instances, however, individual households have benefitted in the short term from the process but this has only occurred where climatic and soil conditions have been particularly favourable.

- Description: This paper discusses the current resurgence of interest in the Linda coordination language for parallel and distributed programming. Particularly in the Java field, there have been a number of developments over the past few years. These developments are summarised together with the advantages of using Linda for programming concurrent systems. Some problems with the basic Linda approach are also discussed and a novel solution to these is presented. The power and flexibility of the proposed extensions to the Linda programming model are illustrated by considering a number of example applications, including a detailed case study of visual language parsing.

- Description: Comrade President, Honorary President, General Secretary and delegates, I present this report on behalf of the National Executive Committee (NEC). Since the last Conference the Union has faced many challenges and difficulties, but has despite this managed to play its rightfull role as a social partner by entering into the national debate of socio-economic transformation. This Conference has to further this advances by debating the crucial issues that underpin our advance to the total socio-economic transformation of our country. We also need to revisit and re-assess the pillars on which our Union rest, and strenghten them through policy formulation - and here I specifically want to isolate the areas of finance and administration. Later in this report I will attempt to highlight some of the crucial areas. Comrade President, allow me to express the NEC's appreciation to the staff for their dedication, loyalty and commitment, to FAWU over the past two years. We want to give them the assurance that their loyalty does not go by unnoticed, and that we will attempt to reward them for this excellent service. May I furthermore use this opportunity to thank the comrades in the National Executive Committee (NEC) and the National Office Bearers for their support and commitment over the past few months. It is through this commitment and dedication that we are able to present this Conference with a report. Comrades, the Annual Audited Financial Statements for the financial year will be tabled tommorrow. To the best of my knowledge this statements represents the financial position of the Union for the year ended 31 March 1997.
