- Description: This paper discusses the associative matching mechanism used in the Linda coordination language for the retrieval of data. There are a number of problems with this mechanism which are discussed in the light of the requirements of applications using Linda. A number of solutions to these problems have been proposed. These are discussed and compared with a new approach to solving these problems. The benefits and the limitations of the new approach are considered, showing how it provides a considerable improvement in this area.

- Description: The Rio Earth Summit of 1992 introduced several new approaches to environmental management under the general heading of sustainable development. One of these approaches has forced conservationists to concede that it is no longer feasible or ethical to exlude resident communities from protected areas, as had been the practice for more than a century. The alternative approach highlighting considerations of social justice and economic empowerment, is to recognise that humans are also part of the local ecology, and to find sustainable ways to maintain local livelihoods along with biodiversity. Especially in the global South, resource-dependant communities associated with protected areas had long been subjected to removals or restrictions by the state, and had been forced to modify livelihoods historically dependant on abundant natural resources, usually resulting in their acute impoverishment. Eastern and Southern Africa had been particulr sites of the former protectionist policies and their frequently tragic sequels for communities. Following the Summit much energy has been expended on finding sustainable alternatives to relocation in these regions, particularly new livelihoods linked to ecotourism From Conflict to Negotiation provides a South African case study of the shift from protectionism to sustainable development in the 1990's. Located on the wild coast of the Eastern Cape, Dwesa-Cwebe consists of a nature and marine reserve with eight adjacent resident communities that have historically depended on local forest, grassland and coastal resources. This are has been the focus of one of the earliest efforts in the 'new' South Africa to restore to the Xhosa-speaking residents ownership of the protected area from which they had been excluded for decades. Unusually the resident initiated the process. While others celebrated the advent of the new democracy in South Africa in 1994, the residents of this remote area, whose grieviences had been ignored during the political transition, planned a protest strategy featuring co-ordinated invasions of the protected area. The protest action succeeded to the extent that it gained massive media attention and provoked the special attention of national and regional goverment, non-govermental organizations (NGOs) and academic researchers. An early academic intervention designed to bring the residents and conservationists together was later expanded. Complementing the roles of goverment and NGOs, environmentalists and socio-cultural anthropologists, among others involved in this project, have attempted to address the conundrum of sustainable development policy implementation in a complex setting. From conflict to Negotiation details the findings of this pioneering research project. It is the story of local empowerment regained as confrontation yielded to negotiation and negotiation yielded co-management, local ownership and developmental partnerships. This landmark study will provoke ongoing discussion and research in an exciting new forum of community development.

- Description: One of the major problems facing schools in South Africa is the difficulty in obtaining modern, up-to-date computer facilities. This paper looks at the use of open source solutions in two government schools in South Africa to demonstrate that it is possible for schools to utilise almost any existing computer to provide effective network solutions.

- Description: Topical corticosteroid formulations have been evaluated by visual grading protocols for many years. Toward a more objective methodology, several instrumental methods have been evaluated for applicability in quantifying the vasoconstriction side-effect that follows corticosteroid application to the skin. Although the chromameter has been adopted by regulatory bodies throughout the world as the current standard for topical bioequivalence determinations, there is considerable criticism of this instrument from several quarters. A preliminary comparison reported here indicates that digital image analysis provides statistically significant results that are similar to those obtained by visual assessment techniques, and shows considerably greater precision than that obtained by the chromameter. Continued evaluation of objective assessment techniques, such as digital imaging, and continued modernisation of regulatory bioequivalence requirements will assist in protecting patients and optimising clinical results.

- Description: The South African water quality guidelines for the protection of the aquatic environment are constantly being updated. The Centre for Aquatic Toxicology of the Institute for Water Research, Rhodes University, uses artificial streams and toxicological methods to contribute to the development and refinement of these guidelines. This study involved the use of 96-hour acute toxicity tests, using zinc sulphate as the toxicant, to determine the suitability of Adenophlebia auriculata as a potential indicator species of zinc pollution. As it is known that experimental environments (e.g. still versus flowing water systems) can influence the tolerance of a test species, the experimental system most suited to this species' abiotic requirements was determined. Static and recirculating systems were compared, with LC50 values calculated for the static systems being 91% lower than those calculated for the recirculating systems. The increased sensitivity to the toxicant under static conditions may be due to the animals being additionally stressed by the less favourable static environment. This suggests that recirculating systems are more suited for toxicity tests using this mayfly. Adenophlebia auriculata appears to be tolerant to zinc when compared to zinc LC50 values for other test species in the literature, and may therefore not be a suitable indicator of zinc pollution in an aquatic environment.
