- Description: With an alarmingly low teledensity in South Africa, just 12%, and not much hope of further wired infrastructure at the local loop level, as the costs incurred are high compared to potential revenue, wireless con-nectivity could be a great asset and service in South Africa. However, the use of unlicensed spectrum in building wireless networks can be comparable to “The Tragedy of the Commons”, the result of selfish be-haviour towards common and limited resources. This paper evaluates the use of 802.11 wireless technologies in building a broadband wire-less network and the effects of high amounts of interference on such a network. The paper concludes that for urban areas 802.11 technologies using unlicensed spectrum is not advisable, unless used in point-to-point links, while its use in rapid rural development (where there is less interference) is very promising.

- Description: Written information to promote patient education is being increasingly recognized as an integral part of quality health care. The main objective of this study was to evaluate the effect of distributing a patient information leaflet (PIL) on knowledge acquisition and recall. Two different PILs were designed for co-trimoxazole tablets: a simple, shorter PIL that incorporated pictograms and text and a text-only PIL that was longer and more complex. Human immunodeficiency virus-positive participants on chronic co-trimoxazole therapy were enrolled from five local primary health care clinics in Grahamstown, South Africa, and were randomly allocated to a Control Group (no PIL), Group A (text-only PIL) or Group B (simple PIL with pictograms).

Shakespeare's Victorian Stage: performing history in the theatre of Charles Kean, Richard W. Schoch: book review

- Description: preprint , This book is a primarily a study of Charles Kean’s productions of Shakespeare’s English chronicle plays at the Princess’s Theatre between 1852 and 1859, a period crucial to the development of ideas of English nationalism. Schoch focuses on these particular stagings as more than drama; as performances of nineteenth century theories of history and historical representation. His project operates under the aegis of the so-called ‘linguistic turn’ in cultural theory, and is suspicious of neo-marxian fundamentalism.
