Gonzalez Cervera AS 《Estudios demográficos y urbanos》1993,8(2):287-306, 483-4
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

Measuring School-Related Stressors in Adolescents 总被引:2,自引:0,他引:2
Some 1620 high school students responded to 68 items that measure adolescent stressors. Thirty-five of the items were based on J. P. Kohn and G. H. Frazer's Academic Stress Scale [1(1986) An Academic Stress Scale: Identification and Rated Importance of Academic Stressors, Psychological Reports, Vol. 59, pp. 415–426] developed in the United States, while the remaining 33 items were developed from P. Strutynski's [(1985) A Survey of Queensland Year 10, 11 and 12 Student Attitudes to Schools and Schooling, State Planning Committee, International Youth Year, Brisbane] lists of the most frequently named problems of 2336 Australian high school students. Confirmatory Factor Analysis was used to test and develop a measurement model developed from an extensive review of previous scales. The High School Stressors Scale emerged from the analytic process and measures nine school-related stressors. For researchers focusing on school-related problems and stressors among adolescents, the HSSS promises to be a very useful instrument. It has sound construct and predictive validity and adequate reliability, as demonstrated by the goodness-of-fit indices the squared multiple correlations. 相似文献
