High technology transfer and computer education: Lessons drawn from the case of a developing country
Dr. John P. van Gigch 《The Journal of Technology Transfer》1984,8(2):57-68
Argentina is a developing country which at present is faced with the advent of high technology and the computer age. In Argentina, like for that matter elsewhere, technology is outrunning our capability to understand it and to take full advantage of its potential. This report describes the conditions prevailing in Argentina to assess the potential impact of high technology in education. Recommendations to implement a program of technology transfer in a typical developing country are drawn. In addition, some of the shortcomings of computer education in Argentina as well as in the United States are indicated. 相似文献

Toxicology analyses and other forensic science data were used to examine the mechanisms through which ethanol increased the risk for death caused by injected street preparations of heroin. The authors studied 505 victims of fatal heroin overdose and compared subjects who had concentrations of blood ethanol greater than 1000 mg/L (n = 306) with those who had concentrations less than, or equal to 1000 mg/L (n = 199). We found significant negative correlations between concentrations of ethanol and morphine (a heroin metabolite) in blood (R2 = 0.11, P = 0.0001 for log10-transformed variables) as well as between concentrations of blood ethanol and bile morphine (R2 = 0.16, P = 0.0001 for log10 bile morphine versus blood morphine). Toxicologic evidence of infrequent heroin use was more common in decedents with blood ethanol concentrations greater than 1000 mg/L than in those with lower concentrations. Our data suggest that ethanol enhances the acute toxicity of heroin, and that ethanol use indirectly influences fatal overdose through its association with infrequent (nonaddictive) heroin use and thus with reduced tolerance to the acute toxic effects of heroin. 相似文献
