Originally published in 1954. This great work surveys the distribution of the world's population and the food production of all countries chosen as important by reason of either their demands on the world food market or their contributions to it. The author concludes that the more advanced countries can be reasonably assured of food supplies for an indefinite period. The less advanced countries can no longer rely on self-contained systems: they must seek co-operation with the advanced countries to supply them with the appliances needed for a more highly developed agriculture. This book at the time gave statesmen and their scientific advisers, agriculturalists and agricultural economists an invaluable new instrument.

For new applications or improvements to existing ones, new zeolites with novel pore systems are desirable. We demonstrate a method for the synthesis of novel zeolites using the ADOR route. ADOR is an acronym for Assembly, Disassembly, Organization and Reassembly. This synthetic route takes advantage of the assembly of a relatively poorly stable zeolite which can be selectively disassembled into a layered material. The resulting layered intermediate can then be organized in different manners by careful chemical manipulation and then reassembled into zeolites with new topologies. By carefully controlling the organization step of the synthetic pathway, new zeolites with never before seen topologies are capable of being synthesized. The structures of these new zeolites are confirmed using powder X-ray diffraction and further characterized by nitrogen adsorption and scanning electron microscopy. This new synthetic pathway for zeolites demonstrates its capability to produce novel frameworks that have never been prepared by traditional zeolite synthesis techniques. ; Publisher PDF ; Peer reviewed

The new South Africa came into being in 1994. The new government inherited the national public service and those of a variety of former provinces and homelands that had to be amalgamated to form a national unified public service. Although this task was accomplished rapidly, the resulting public service was very large, and exhibited many features of traditional bureaucracy, including hierarchical structures, limited automation and IT applications, low levels of training, a poor work culture, language and cultural barriers, and an overall orientation towards inputs and processes rather than service delivery and results. Within the first three years of the new order, substantial effort was devoted to reforming the bureaucracy. New public service legislation and regulations were introduced, new and powerful central personnel agencies were created, English became the language of administration, and substantial authority was devolved to departments and provinces. Despite these reforms, progress in improving results in terms of service delivery, especially to previously disadvantaged communities, was mixed. Towards the end of the 1990s increased attention was paid to means of improving service delivery. Three important initiatives in this regard were Batho Pele (1997), the adoption of eight nationwide principles for better service delivery; a public private partnerships initiative (2000) and the promotion of alternative service delivery. While alternative service delivery initiatives are largely at pilot stage, they offer a promising alternative both to traditional bureaucracy (with its cost and poor service delivery focus) and to a narrow version of privatisation (which could involve heavy social costs, job losses, and regressive redistribution of wealth). This paper reviews these developments and outlines some promising alternative service delivery pilot projects.
