"Social and economic indicators depict Mexico as a country of intermediate development. It is also in intermediate stages of demographic and epidemiologic transitions. When these traits are translated into socio-demographic perspectives, all projections indicate that for the next fifty years we can expect: (i) percentage decreases in child and teen-age populations, (ii) large percentage and absolute increases in adult population, and (iii) important increases in the elderly population.... Among elders death due to infectious diseases is less common than within other sectors of [the] population. Mortality associated with chronic ailments has increased, with recent and remarkable changes during the last twenty years. This transformation is not evenly distributed. It is more accelerated in developed and urban areas as contrasted with the rural and less developed." (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 article reviews Mexican research of female migration. An analysis is made of socio-demographic and anthropological studies that cover the relations between inequality among the genders, the causes and features of migration, and the work performed by female migrants in their places of origin and destination. The paper responds to the growing interest shown in international literature [on] migration in order to determine the influence of gender identity in the motivations and features of the migration of women, as well as the consequences of spatial mobility on their social conditions and their autonomy."

"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."
