Excessively delayed maternal reaction after their perception of decreased fetal movements in stillbirths: Population-based study in Japan

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.

An Assessment of Alternative Measures of Time Use

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.     

Gender and the Internet

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.     

How Changes in Sending Countries Influenced Patterns of Interracial Families Through Intercountry Adoption

The racial characteristics of children adopted from abroad by American parents have fluctuated sharply over time in response to changing legislation and attitudes toward intercountry adoptions in the United States and the sending countries. This study investigates how the likelihood of parents adopting a White versus non-White child varies by the characteristics of the adopted child, the parents, and the household. Our analyses, using the 2008–2012 American Community Survey, show that parents consider the child's age, sex, and health; the presence of adopted and biologically related children in the household; and shifts in the availability of children across major sending countries.     

Paid maternal leave is associated with better language and socioemotional outcomes during toddlerhood

The United States is the only high-income country that does not have a national policy mandating paid leave to working women who give birth. Increased rates of maternal employment post-birth call for greater understanding of the effects of family leave on infant development. This study examined the links between paid leave and toddler language, cognitive, and socioemotional outcomes (24–36 months; N = 328). Results indicate that paid leave was associated with better language outcomes, regardless of socioeconomic status. Additionally, paid leave was correlated with fewer infant behavior problems for mothers with lower levels of educational attainment. Expanding access to policies that support families in need, like paid family leave, may aid in reducing socioeconomic disparities in infant development.     

Family Types, Direct Money Transfers from Parents, and School Enrollment among Youths

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.

Determinants of Women's Entry into Self–Employment

Objective . Building on recent studies that have shown how employment– and family–related characteristics are uniquely intertwined in facilitating women's decisions to work for themselves, I examine the process of transitions into self–employment among white, African–American, and Hispanic women. Methods . This study analyzes data from the National Longitudinal Survey of Youth, a national probability sample of those born between 1957 and 1964, which allows me to apply a dynamic model for studying women's employment transitions. Results . Regardless of race or ethnicity, factors such as work experience and the presence of a spouse encourage women to become self–employed. At the same time, the distributions of these characteristics for African–American women, and to a lesser extent Latinas as well, significantly account for their slower entry into self–employment. The effect of children on women's entry into self–employment, which earlier studies often found to be positive, especially among whites, is mixed. Conclusions . These findings reveal significant racial/ethnic differences in the process of female self–employment and also call into question the view that self–employment allows working mothers to better combine their careers with family responsibilities than does wage/salary sector employment.
