This article will trace the history and effects of the PPI from the time of its original concept by the FDA in the early 1970's to its current status. It will also address the response to this FDA initiative by the industry, medical community and consumer groups. Initiatives in other countries and future issues will also be discussed.  相似文献

The 1994 International Conference on Population and Development (ICPD) opened the dawn of a new era in discourse over population. A newfound consensus was reached between North and South which was not there during the two previous world population conferences in Bucharest and Mexico. While consensus was reached at the 1994 ICPD on the need for action, however, debate over population is far from settled. Causes of population growth, the links between population growth and economic development, and environmental degradation remain controversial topics. The authors analyze the basis of the ICPD consensus at the local, national, and global levels. They also compare the development discourse to the political discourse over population. Both discourses emphasize different aspects of a far more complex reality. The question is which discourse to choose as a basis for drawing policy recommendations. The emerging view on the way to Cairo was that consensus would be achieved on the basis of development discourse. Success on the action plan rests upon the belief that more contraceptives, more health services, and more schools will be enough to reduce fertility rates. The political discourse, however, is better than the development discourse as a basis for policy making because it stresses the need for integration rather than running the risk of exclusion. The political discourse is also more demanding.  相似文献

"A bibliographical review serves to analyze the role of urban growth in patterns of international labor-force migration, as well as the effect of this migration on the development of the countries of origin, especially on their cities. While the review confirms the general idea that international migrants are either peasants or highly qualified personnel, it also shows that qualified workers are increasingly involved in international labor movements and that a great part of them come from large cities. It is to be expected that in these circumstances large cities of the countries of origin will become more integrated to international migratory systems." (SUMMARY IN ENG)  相似文献
