The authors reviewed at autopsy the causes of death of 274 patients with evidence of intravenous drug abuse who had been admitted to a large public hospital. There were 127 who died from diseases unrelated to intravenous drug abuse, and in 41% of these, chronic alcoholism was implicated. Deaths from overdose syndromes and drug-related organ pathology comprised only 11% of all cases. The mean age at death was 39 years. There was a male/female ratio of 3.6:1. Half of all patients died from infection--72 from acquired immunodeficiency syndrome (AIDS) alone. These findings indicate that persons hospitalized with a history of intravenous drug abuse usually die from causes other than overdose and that AIDS and chronic alcoholism are significant problems. Emphasis should be placed upon detecting "hidden" intravenous drug deaths to provide more accurate statistical information. 相似文献

The relation between domestic R&D and imports of technology is examined for 10 countries. Simple regressions revealed strong complementarity for each of the countries. Multiple regressions including GNP per capita and number of scientists and engineers were performed for the five countries with time series for all the variables. Strong complementarity was found between technology imports and domestic R&D and other variables for Japan and South Korea, weak for France, none for Germany and the US. Excluding government-financed R&D in the US resulted in a substitutive relation. Japan revealed a sharp decline in the ratio of technology payments to R&D spending; Korea is following in its steps. Complementarity appears to weaken in later stages as technology development strategies shift from dependent to imitative to autonomous or offensive technology development. 相似文献

The welfare state is often accused of being counterproductive: as the scope of public responsibility expands, private morality (especially altruism and benevolence) atrophies. This essay surveys psychological findings for evidence, which turns out to be broadly consistent with either of two models of moral development, each bearing distinct policy implications. The model of morally keeping in practice that is implicit in the term moral atrophy suggests the need for frequent opportunities to exercise moral skills, which would seem inconsistent with the welfare state. Alternatively, the model of moral character-building favoured by both philosophers and ordinary discourse would require only occasional reminders of one's moral principles. On this model, benevolence could usefully supplement the welfare state. 相似文献
