Over the past decades the rate of completed suicide has remained quite stable, whereas that of suicide attempts seems to have increased (to the extent it has been studied in defined regions). These are puzzling observations, since depression is the major suicide precursor and and since antidepressants have been increasingly used over the years in the treatment of depression. These observations have not attracted sufficient attention, possibly because they do not accord with consensus opinions about depression treatment in psychiatry today. This paper discusses a number of possible explanations that not only deserve, but are definitely in need of systematic investigation. 相似文献

ELAIN is an automation project for the processing of export-license applications by the Bureau of Export Administration of the Department of Commerce (DOC). The project is unusual in that it was implemented by administrators without going through normal approval channels. The relationships between the change agent and the agency participants can best be described by Havelock's diffusion-adoption model, which depicts the execution as a one-way relationship from sender to receiver. The more complex models that were examined do not apply because this project was inauguated and furthered by bureaucrats, as opposed to the more usual participation of political appointees. The ELAIN system uses commercial valueadded telecommunications vendors to trasfer the information between the exporters and DOC. Industry used its own funds to develop the necessary special features, with repayment possible only if exporters used their sevices, paying fees for this convenience. No precedent for this type of arrangement was found, hence it is considered to be a social invention as well as an innovation. 相似文献

The Taiwan Strait crisis of 1996 was the greatest challenge to Sino‐American relations in several decades. This study examines the crisis and its implications for US security policy. It outlines US policy toward the defense of Taiwan, discusses the US response to Beijing's military intimidation of Taiwan and analyzes several of the major lessons gleaned from the crisis. The paper suggests that, while China's aggressive behavior should not lead to a dramatic shift in the American position toward Taiwan's defense, some modest adjustments in policy may be warranted. 相似文献
