- Description: This paper describes the assumptions and results of a study to assess whether cultivation of medicinal plants can serve as a tool for combined biodiversity conservation and poverty alleviation. The study was carried out in the Amatola region of Eastern Cape, South Africa, where sustained beliefs in medicinal plant use, also under non-traditional conditions, has resulted in an increase in commercial demands. It was based on the assumption of poverty alleviation not only referring to an increase in income and labour, but also an increase in social capital and human dignity. The study assessed the local perceptions of the use and cultivation of medicinal plants and the need for conservation of these plants, as well as the features of already ongoing cultivation practices and options for increased cultivation. It consisted of participatory assessments in three villages involving around 250 persons and participatory trials with 14 rural women selling medicinal plants on urban markets. The study indicated that the growing demand for medicinal plants is related to the great cultural significance attached to medicinal plants.

Know your rights! A basic guide for domestic workers in South Africa

- Description: The demand for domestic services has increased globally during the last two decades and today domestic workers constitute a large portion of the workforce, especially in developing countries. Yet domestic work is undervalued and poorly regulated, and many domestic workers are underpaid and unprotected. This has been recognised by international organisations, such as the International Labour Organisation (ILO). The struggle of domestic workers has lead to improvements to their rights and conditions in many countries. Yet working conditions and wages remain poor in many countries, including South Africa. This booklet sheds light on this problem. There are 888 000 domestic workers in South Africa, which accounts for 7% of total formal employment (Labour Force Survey, May 2010). The vast majority of these workers do not belong to a trade union and do not partake in collective bargaining or are unaware of their rights to bargain and to join trade unions. The South African Domestic Services and Allied Workers Union (SADSAWU) is a trade union for domestic workers in South Africa and campaigns for the improvement of rights and conditions of domestic workers. It recognises that it is not as powerful as it could be and it would have a bigger influence on the legislating authorities if there were more members which were strongly organised. There are numerous difficulties to organise domestic workers, some are related to the education level of the workers and some lies within the nature of the work (many are live-in workers and therefore have no contact with other domestic workers as a natural part of their work). However, SADSAWU has over many years built up a lot of experience and developed a solid vision to build a strong domestic workers movement, and is therefore well placed to fight these difficulties. This booklet also serves as an organising tool for domestic workers. The aim is to raise awareness of the rights of domestic workers and to encourage workers to organise.

Spatial and seasonal distribution patterns of the ragged-tooth shark Carcharias taurus along the coast of South Africa

- Description: Off South Africa, the ragged-tooth shark Carcharias Taurus has been occasionally reported from the West Coast, but it is more commonly found along the East and South coasts from Cape Town to northern KwaZulu-Natal (KZN) (Bass et al. 1975, Smale 2002). Mating is thought to occur off the south coast of KZN from October to late November (G Cliff, Natal Sharks Board, unpublished data). Pregnant females then move northward to spend the early part of their gestation in the warmer waters of northern KZN and possibly southern Moçambique. During July and August, the near-term pregnant females begin to move southwards towards the cooler waters of the Eastern Cape (Wallett 1973, Bass et al. 1975, G Cliff, unpublished data), where they give birth from September to November (Smale 2002). After parturition, many of the females migrate back to KZN. The whereabouts of mature males outside of the mating season is unclear. These broadscale distribution and migratory habits for C. taurus have been inferred from limited catch records obtained for only parts of its range along the South African coast.

- Description: The oxidation of acetaminophen was studied at a glassy carbon electrode modified with multi-walled carbon nanotubes and a graphite paste. Cyclic voltammety, differential pulse voltammetry and square wave voltammetry at various pH values, scan rates, and the effect of the ratio of nanotubes to graphite were investigated in order to optimize the parameters for the determination of acetaminophen. Square wave voltammetry is the most appropriate technique in giving a characteristic peak at 0.52 V at pH 5. The porous nanostructure of the electrode improves the surface area which results in an increase in the peak current. The voltammetric response is linear in the range between 75 and 2000 ng.mL−1, with standard deviations between 0.25 and 7.8%, and a limit of detection of 25 ng.mL−1. The method has been successfully applied to the analysis of acetaminophen in tablets and biological fluids.
