This study examines whether levels of father engagement (e.g., verbal stimulation, caregiving, and physical play) vary by race/ethnicity using a model that controls for fathers' human capital, mental health, and family relationships. It also tests whether the models work similarly across race/ethnic groups. Its sample of N=5,089 infants and their families is drawn from the Early Childhood Longitudinal Study - Birth Cohort (ECLS-B). We found that, after including controls, African American and Latino fathers had higher levels of engagement in caregiving and physical play activities than White fathers. There were no differences in verbal stimulation activities across race/ethnicity. Fathers' education (college level) predicted more verbally stimulating activities whereas fathers' report of couple conflict predicted less caregiving and physical play. Although levels of engagement differed across the groups, the overall models did not differ by race/ethnicity, except for physical play. African American mothers who reported high levels of depressive symptoms had partners who engaged in more physical play than White mothers with high levels of depressive symptoms. 相似文献

Fatherhood in the twenty-first century 总被引：11，自引：0，他引：11
The twentieth century has been characterized by four important social trends that have fundamentally changed the social cultural context in which children develop: women's increased labor force participation, increased absence of nonresidential fathers in the lives of their children, increased involvement of fathers in intact families, and increased cultural diversity in the U.S.. In this essay, we discuss how these trends are changing the nature of father involvement and family life, and in turn affecting children's and fathers' developmental trajectories. We end with an eye toward the twenty-first century by examining how the children of today will construct their expectations about the roles of fathers and mothers as they become the parents of tomorrow. This life-span approach to fatherhood considers the broader sociohistorical context in which fatherhood develops, and emphasizes the urgent need to consider mothers, fathers, and family structure in future research as we seek to understand and model the effects of parenting on children's development. 相似文献

验证收缩骨骼肌细胞葡萄糖转运蛋白4（GLUT4）基因的表达在转录水平上是否受转录抑制子Ⅱ型HDAC5蛋白（简写为HDAC5）的调节。研究运用运动模拟信号5-氨基-4-甲酰胺咪唑核糖核苷酸（AICAR）和HDACs抑制剂SCRIPTAID孵育骨骼肌细胞。用蛋白印迹技术测定HDAC5蛋白表达,定量RT-PCR法检测GLUT4 mRNA表达。与无AICAR的对照组相比,AICAR组骨骼肌细胞内HDAC5减少了29%,并伴随有124% GLUT4 mRNA的增加,但肌细胞内HDAC5的蛋白总量无变化;使用HDACs抑制剂SCRIPTAID刺激骨骼肌细胞能够明显增加核心组蛋白乙酰化水平和上调GLUT4基因的表达。这些结果提示,通过AICAR和SCRIPTAID分别减少或抑制核HDAC5均能上调骨骼肌细胞GLUT4基因的转录,HDAC5可能在转录水平上对肌肉收缩引起的GLUT4基因的表达起着重要的调节作用。 相似文献
