Using an ordered logit model on representative survey data, we study attitudes about who should provide for the livelihood of the elderly in two aging societies—Germany and Japan. We find that in both countries, those with higher income are more inclined toward the private option, whereas age has the opposite effect. Part-time work status negatively (positively) affects the inclination toward a government-based pension system in Japan (Germany). Other significant influences are the pensioner status of the respondents in Japan and specific left-wing party support in the case of Germans.  相似文献

Background

Decreased fetal movements are associated with adverse perinatal outcomes, including stillbirth. Delayed maternal visits to a health care provider after perceiving decreased fetal movements are frequently observed in stillbirths. Informing pregnant women of the normal range of fetal movement frequency is essential in their earlier visits in order to prevent stillbirth.

Aim

To investigate the fetal movement frequency in late pregnancy and the effects of associated perinatal factors.

Methods

This prospective multicenter study was conducted in 20 obstetric facilities in our region of Japan. A total of 2337 pregnant women were asked to record the time it took to perceive 10 fetal movements by the modified ‘count to 10’ method every day from 34 weeks of gestation until delivery.

Findings

The 90th percentile of the time for the maternal perception of 10 fetal movements was 18–29 min, with a gradually increasing trend toward the end of pregnancy. The numbers of both pregnant women giving birth after 39 weeks’ gestation and infants with a birth weight exceeding 3000 g were significantly higher in mothers who took ≥30 min to count 10 fetal movements than in those who took <30 min.

Conclusion

The maternal perception time of fetal movements shows a gradually increasing trend within 30 min for 10 fetal movements by the modified ‘count to 10’ method. Informing pregnant women of the normal range of the fetal movement count time will help improve the maternal recognition of decreased fetal movements, which might prevent fetal death in late pregnancy.  相似文献

Background

Fetal movement is the most common method to evaluate fetal well-being. Furthermore, maternal perception of decreased fetal movements is associated with perinatal demise. Previously, we showed that perception of decreased fetal movements was the most common reason for mothers visiting the outpatient department among those who had stillbirths in our region. Further investigation of stillbirths with decreased fetal movements is essential to find a possible way of preventing stillbirth.

Aim

To investigate maternal reaction time after their perceiving decreased fetal movements among stillbirths in our region of Japan.

Methods

This is a population-based study of stillbirths in Shiga Prefecture, Japan conducted from 2007 to 2011. We sent a questionnaire to each obstetrician who had submitted the stillbirth certificate. We reviewed and evaluated the questionnaires returned from the obstetricians.

Findings

There were 66 cases (35%) with decreased fetal movements among 188 stillbirths in Shiga during the study period. The number of maternal visits to outpatient department after perception of decreased fetal movements within 24 h was only seven (11%) among 64 stillbirths diagnosed at outpatient department.

Conclusion

We conclude that delayed maternal visit after perceiving decreased fetal movements is frequently observed in stillbirths. Promoting more thorough maternal education on fetal movements, including emphasizing earlier visitation after perceiving decreased fetal movements, may prevent stillbirths.  相似文献

Although time use has received much attention by social scientists as an index of resource allocation and social relations across groups, only a few studies have carefully assessed the relative strengths and weaknesses of the existing methods of measuring time use: time diary (TD), stylized (S) respondent report, and experiential sampling method (ESM). We note the varying degree of biases that arise in part from the extent of detail in the information collected by the three methods. Using findings from our analysis of the structure of these methods, we hypothesize that there are empirical exceptions to previously reported common findings that TD provides less biased information on time use than does S—namely (a) when labor market workers report their time spent on labor market work, and (b) when the historical trend in time, rather than the absolute level, is studied. Empirical results confirm our prediction and show that, among individuals who work regularly, TD and S estimates of labor market work hours reported by the same persons correspond closely to one another. In addition, when assessing historical trends, TD and S values correspond closely to one another, although TDs yield some inexplicable deviations from the trend even when the sample and the codes are carefully standardized. We also provide notes on a strategy of standardization for diary codes that are distinct across historical or national contexts.  相似文献

Objective. This article examines whether there are differences in men's and women's use of the Internet and whether any such gender gaps have changed in recent years. Methods. We use data from several surveys during the period 1997–2001 to show trends in Internet usage and to estimate regression models of Internet usage that control for individuals' socioeconomic characteristics. Results. Women were significantly less likely than men to use the Internet at all in the mid–1990s, but this gender gap in being online disappeared by 2000. However, once online, women remain less frequent and less intense users of the Internet. Conclusions. There is little reason for concern about sex inequalities in Internet access and usage now, but gender differences in frequency and intensity of Internet usage remain.  相似文献

Intrafamily resource transfers have not been studied extensively as a process that may help reduce the well-being disadvantage of stepchildren in parental remarriages relative to biological children in parental first marriages. The process is examined here by analyzing the link between direct parental money transfers and academic outcomes, as measured by enrollment. I develop and test two alternative hypotheses pertaining to a part of this link, which distinctly applies to children of remarried stepfamilies--the component not shared with children in intact families. An adaptive strategy hypothesis posits a well-being enhancing distinct component, operationalized as a positive interaction effect between measures of parental transfers × stepchildren in parental remarriages. A compromised use hypothesis posits a well-being compromising one, implying a negative interaction effect. Two sets of results from analyzing data on 18-21 year olds over multiple years (Nyouth-age=5,736, Nperson=3,615) in the first five waves of the National Longitudinal Survey of Youth 1997 (NLSY97) support the adaptive strategy hypothesis: a) the interaction effect (income received from parents × being a stepchild in a parental remarriage) has a positive sign; and b) this interaction effect is consistently positive, whether the youth is at risk of attending high school or college, even when the direction of the shared component of the link, as measured by the main effect of income from parents, varies by the level of schooling. The results suggest the presence of a robust well-being enhancing money transfer mechanism supporting children in some remarried stepparent families.  相似文献
