"Tijuana has been the most extraordinary example of the modern demographic history of the [Mexican] northern border. This article is an essay on the economic, social, and demographic development of this important urban center during this century. Its purpose is two fold. On the one hand, to understand Tijuana's general population change in light of a unique socioeconomic development in the country, which has been characterized by a close dependence on the United States as well as by the creation of several federal programs aimed [at integrating] the natural economies. On the other hand, to introduce the discussion of the Mexico-United States border region to the non-specialist in this field." (SUMMARY IN ENG) 相似文献

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."
