Data from the 1987 National Health and Fertility Survey were used to explore trends and differentials in unwanted fertility in Mexico. Women were classified in three educational categories: illiterate or incomplete primary, complete primary or some secondary, and complete secondary or more. The four urbanization categories were: under 2500; 2500 to 19,999; 20,000 and more; and metropolitan areas. The place of primary socialization was the place of residence until age 12. Two categories of employment of household head were included, agricultural or nonagricultural. The categories for mother's employment considered employment until the union and employment between the time of union and the birth of the first child. The proportion of births that were unwanted was estimated by calculating the total fertility rate for the year before the survey and comparing it to desired family size. The "total desired family size" was 2.4 for the entire sample. In other words, nearly 37% of the total fertility rate was undesired. The greatest differentials in percentages of undesired fertility were found in educational categories. 40.7% of the total fertility rate in the least educated groups vs. 13.6% in the most educated groups was undesired. Differentials in the other categories ranged from 1.9 for a history of employment before the birth of the first child to 8.8 for agricultural or nonagricultural employment of the household head. When effects of education were controlled, the percentage of undesired fertility declined as educational level increased for all rural or urban residence categories, places of socialization, and employment groups except women who worked before the first child was born. Women with more education, urban residence, and with histories of employment had the lowest levels of undesired fertility.  相似文献

With Bill Clinton's new reforms only a month away, the health-care system is on the operating table--and the doctors are under the knife. Americans have a love-hate relationship with physicians: they like the care that doctors provide but hold them to blame for the nation's health-care mess. NEWSWEEK looks at how the culture of medicine may change, assesses doctors' fears--and examines the brave new world of HMOs.  相似文献

The author relates three cases of conflict which he has observed in Cairo and recognizes patterns that cut across each of these stories. The stories shed light on how people in Egypt approach and deal with conflict; in addition, they may help readers understand conflict in their home culture as well as be instructive on how to listen to conflict in different cultures. Six general themes in the way Egyptians approach or handle conflict are identified, and each of these themes is analyzed.  相似文献

Lawyers and judges faced with a contemporary constitutional issue must try to construct a coherent, principled, and persuasive interpretation of the text of particular clauses, the structure of the Constitution as a whole, and our history under the Constitution--an interpretation that both unifies these distinct sources, so far as this is possible, and directs future adjudication. They must seek, that is, constitutional integrity.  相似文献
