Scientific, institutional and personal rivalries between three key centres of geographical research and scholarship (the Academy of Sciences Institute of Geography and the Faculties of Geography at Moscow and Leningrad State Universities) are surveyed for the period from 1945 to the early 1950s. It is argued that the debates and rivalries between members of the three institutions appear to have been motivated by a variety of scientific, ideological, institutional and personal factors, but that genuine scientific disagreements were at least as important as political and ideological factors in influencing the course of the debates and in determining their final outcome. 相似文献

There is growing recognition and concern that too many of the 20,000 foster youth who age out of the child welfare system each year 1 in this country do so without the basic necessities of housing, education, employment, and health care. The purpose of this article is to outline the problems facing foster youth as they leave care and to detail, as a case study, the steps taken by KidsVoice, a Pittsburgh legal services organization representing almost 5,000 dependent children each year, to help youth in foster and substitute care transition more successfully to adulthood and independent living. 相似文献

Indian Buddhist sources speak of five sins of immediate retribution:
murder of mother, father, an arhat, drawing the blood of a buddha, and
creating a schism in the monastic community. This category provides the
paradigm for sinfulness in Buddhism. Yet even these sins can and will, be
expiated in the long run, demonstrating the overwhelmingly positive nature of
Buddhist ethics 相似文献

The Food and Drug Administration (FDA) and the European Agency for the Evaluation of Medicinal Products (EMEA) recently issued documents encouraging sponsors to consider microdose testing before launching Phase I trials, and many commentators predict that such methodologies will be applied more routinely in drug development. However, exploratory testing has provoked several ethical criticisms. Skeptics question the value and validity of microdose trials, and whether they present a reasonable balance of risks and benefits for subjects. Another major criticism is that such studies serve mainly commercial ends. The present article explores these and other ethical concerns for studies conducted in the oncology setting. It concludes that microdosing is not inconsistent with prevailing practices in Phase I research, and that in principle, such studies could strengthen the ethical basis for Phase I trials by providing them better evidentiary justification. 相似文献
