Tort reform is controversial because of the need to balance cost considerations with the legitimate needs of plaintiffs who have suffered malpractice injury. In addition, proponents and opponents of the different proposals often formulate their positions based largely on anecdotal evidence and concerns of special interest groups rather than careful studies. As a result, it may be some time before malpractice reform is addressed comprehensively at the federal level, leaving the states to their own reform devices. 相似文献

"This work...examines the cultural dimension of sexuality and fertility of women from [low-income] sectors in Peru. It intends to explain the cultural processes that fall into the intermediate variables of fertility, such as marriage rate, contraception, breastfeeding and...abortion. These dimensions of sexual and reproductive life are analyzed according to two explanatory dimensions: generation and cultural context of socialization. The general hypothesis is that a cultural process of homogenization of the values and behaviors has been taking place over sexuality, in such a way that the younger generations will show similar standard behaviors and values no matter their context of socialization; in the meantime, in the older groups there will exist contextual differences in these dimensions."

This document summarizes the activities of the American Public Health Association International Clearinghouse that operated with funding from the US Agency for International Development for 16 years beginning in 1979. The Clearinghouse was established to improve access to information on infant feeding and maternal nutrition for health practitioners and decision-makers in Africa, Asia, and Latin America. By 1996, the Clearinghouse had created a substantial and accessible resource for USAID, and its activities included 1) developing an international center for information and materials on maternal and child nutrition and related issues in developing countries, 2) sharing lessons learned through a publication of a regular bulletin ("Mothers and Children"), 3) training staff from field-based organizations on information production and management, and 4) establishing a network of national and regional nutrition and health-related resource centers to increase access to locally published and unpublished information. Thus, the Clearinghouse was more than a library or distribution center; it identified key materials, repackaged information to increase accessibility, and monitored information use. Although the Clearinghouse project ended in 1996, the website on women's rights to maternity protection continues to provide access to information and to encourage dialogue and networking. The lessons learned from the project lead to the conclusions that users' needs must be the basis for increasing information access, that local capacity must be increased through new technologies and traditional methods, and that information resources must be used strategically to ensure equitable access. 相似文献

123 out of 850 suicides that occurred in the Canton of Geneva between 1980 and 1989 were suicides by submersion. 75 women and 48 men committed this kind of suicide. 89 victims (57 women and 32 men) were older than 40 years. In all cases the spatial distance between the residence of the suicides and the nearest river or lake was determined; a correlation with the tendency to commit suicide by drowning was not evident. More than geographical factors, the psychological influences have to be considered. 相似文献
