Patronato de Nutrición introduced a range of 18 optional agricultural technologies in the indigenous community of Chalite, Panama. Three of the technologies were adopted by more than half of the farmers surveyed, while an additional eight technologies were adopted by between 20 per cent and 50 per cent of the farmers. Farmers were more likely to adopt technologies associated with familiar crops, previously promoted by other groups, or requiring limited labour or financial resources. The article shows how development groups can quickly reduce the number of technologies promoted in order to deliver services more effectively. 相似文献

Despite the importance of European Union negotiations, the majority of scholarly attention has not been directed towards the means by which policy is coordinated in member states. This article addresses one aspect of this gap by focusing upon the structures which existed for UK policy making during the 1990-91 IGC negotiations. Particular emphasis is attached to the key role of officials, who often proved crucial to the extraction of compromises at the European level, and the manner by which policy was constrained by the inability of the Prime Minister to dominate Cabinet. 相似文献

A simple method of detection was developed for gamma-hydroxybutyrate (GHB). The method involves the derivatization of GHB using a hexyl-chloroformate procedure in aqueous media (such as water or urine), extraction of the derivatization product directly from the sample using solid-phase microextraction, and subsequent separation and detection with gas chromatography quadrupole ion trap mass spectrometry. The deuterated form of GHB (GHB-D6) is used as an internal standard for quantitation. The method was linear for GHB-spiked pure water samples from 2 to 150 microg/mL GHB with a detection limit of 0.2 microg/mL. Spiked urine samples showed linearity from 5 to 500 microg/mL GHB with a detection limit of 2 microg/mL. The SPME-GC/MS method is applied to actual case samples, and the results are compared to those values obtained using a conventional GC/MS method. Sensitivity and linearity are comparable to those seen using traditional methods of separation, yet the SPME method is superior due to the simplicity, speed of analysis, reduction in solvent waste, and ability to differentiate between GHB and gamma-butyrolactone (GBL). 相似文献
