There was a split between North and South over environmental issues at the 1992 Earth Summit. A similar rift may re-emerge as the British Overseas Development Administration opens management of its training programmes to competition in 1993. Emerging institutions offering training on environmental matters in Asia have the advantages of similar natural environments, relevance, and lower costs. As these increasingly realise that ODA funding for third-country training is not tied to British universities, they will compete with UK training institutions. The existing one-way student traffic to UK institutions can benefit from competition. Modern information and communication systems now allow training networks to interlink among institutions in both the North and the South. The UNCED commitment to increased training on environmental issues provides an opportunity for a major new environmental-training project managed by an independent academic/development institute or NGO.  相似文献

In a multiple-reversal time-series design, additional plainclothes youth guidance officers were assigned to patrol and to issue juvenile warning citations in one of two target areas during school hours on weekdays. The presence and activity of these officers resulted in modest but consistent reductions in the number of criminal incidents reported in the target area. An untreated control area showed no consistent changes in the rates of criminal incidents. Issuance of juvenile citations appears to be a modestly effective crime control technology which may be implemented in a cost-efficient manner.  相似文献
