Abstract In order to match birth and family planning acceptance records and thereby to obtain estimates of pre- and post-acceptance fertility, use is made of seven-digit national identity card numbers, issued to all adult West Malaysians. These unique numbers are recorded on live-birth records and national family planning programme acceptor records of West Malaysian women. The application and preliminary results of this method of direct computer matching of these sets of records for assessing the effects of a family planning programme on fertility are described. Pre- and post-acceptance fertility rates are presented in terms of contraceptive methods used, and the key characteristics of race and age of programme acceptors, and are discussed in terms of marital duration and number of children at the time of acceptance. 相似文献

Mothers' time‐use patterns were compared in families in which infants spent more than 30 hours per week in child care (In‐Care group; n= 143) versus 0 hours per week (At‐Home group; n= 183) from birth to 6 months of age. In‐Care group mothers spent about 12 fewer hours per week interacting with their infants, for about 32% less time; fathers of these infants were more involved in caregiving. The groups did not differ in the quality of mother‐infant interaction. In the In‐Care group, quantity of interaction was related to greater separation anxiety and concerns about effects of maternal employment. Time‐use data were not related to child outcomes at 15 months of age. Results suggest that the effect of extensive time spent apart on the quantity and quality of mother‐infant interaction may be smaller than anticipated. 相似文献

We analyze the wealth ejfects of the Texaco racial discrimination lawsuit both on the shareholders of Texaco and its major
U.S. competitors. Employing a comprehensive data set which included every case docket entry and every Wall Street Journal
article on the case as an experimental stimulus, our findings suggest that the overall cost of the case to Texaco shareholders
exceeded $500 million, that Texaco's tribulations had little, if any, impact on the share prices of its major competitors,
and that Wall Street Journal coverage of the case was highly correlated with significant changes in Texaco stock prices. This
last finding provides significant support for Hite 's suppostion that newspaper editors “key ” on ex post stock price changes
in selecting the events to be covered in the next day's edition.
The authors are grateful to Kee Chung for helpful comments on earlier drafts and also acknowlege the help-ful assistance of

Changing Frameworks in Attitudes Toward Abortion 总被引:1,自引:0,他引:1
For more than two decades, legal abortion has been the subject of heated political debate and adversarial social movement activity; however, national polls have shown little change in aggregate levels of support for abortion. This analysis examines how the determinants of abortion attitudes have changed between 1977 and 1996, using data from the General Social Surveys. While in early time periods, whites were more approving of abortion than blacks, that pattern had reversed by the late 1980s. After controlling for other factors, older people are more accepting of abortion throughout the two decades, while gender is generally unrelated to abortion views. Catholic religion weakens slightly as a predictor of abortion attitudes, while religious fundamentalism and political liberalism increase in explanatory power. The associations between attitudinal correlates and abortion approval also change over this time period. Religiosity becomes a less powerful predictor of abortion attitudes, while respondents' attitude toward sexual freedom and belief in the sanctity of human life increase in their predictive power. Support for gender inequality remains a weak but stable predictor of abortion attitudes. This pattern of results suggests that the public is influenced more by the pro-life framework of viewing abortion than by the pro-choice perspective. 相似文献

Studying and Measuring Civility: A Framework, Trends and Scale 总被引:1,自引:0,他引:1
Abbott L. Ferriss 《Sociological inquiry》2002,72(3):376-392
Four essential questions for the study of civility involve developing a definition of the term, determining its effects, establishing trends, and predicting the consequences of civility. A framework for studying it includes the actors, their gender, situations and settings, occupational role requirements, the cultural imperatives defining civility, and the processes through which it is learned. Objective measures of civility in the United States show its variability and change. Four items in the 1996 General Social Survey (GSS) are combined to form a scale of civility. Correlates of the scale show that civility does not differ by gender, color, or region. It is weakly associated with income but is significantly associated with education, occupation, and health. Age, education, and health provide a predictive model of civility. Anger, an emotional aspect of interpersonal exchange, reveals reactions characteristic of civil behavior: waiting for anger to pass before responding, trying to forget the incident, not thinking of revenge, not walking away from the situation, and not yelling or hitting. Hypotheses are proposed for further study that involves age, marital status, occupation, health, and emotional control. 相似文献

Adult members of 79 Albanian families who had fled from Kosovo to Macedonia during the immediate postwar period (June–August 1999) were interviewed. In conjunction with therapeutic intervention, the Harvard Trauma Questionnaire (HTQ) and the General Health Questionnaire (GTQ) were administered. Trauma symptoms as measured by the HTQ and psychological distress as measured by the GHQ were highly correlated. The best predictor of psychological distress was severity of the trauma experienced. Refugees with high educational attainment had fewer trauma symptoms than those with lower educational attainment. Refugees who lived with host families in towns showed fewer trauma symptoms than those who lived in camps, but they were also more highly educated. The results of hierarchical multiple regression analyses suggested that educational attainment may mediate the effect of place of residence. Educational attainment may be an indicator of resourceful and effective coping strategies that ameliorate the effects of trauma. 相似文献

Unemployment rates differ widely and persistently across counties. This article examines equilibrium forces related to this geographic disparity with a focus on California. We show that although seasonal variation in employment can account for some of the differences, it cannot explain the total variation. Factors such as educational attainment, age, and gender appear to be strongly related to unemployment differences. Individuals living in higher‐unemployment areas also have a lower propensity to migrate. Because migration is usually considered to be the main equilibrating force, this evidence helps further explain why unemployment rates across counties are persistently different. 相似文献
