CSRP's Impact on low-income preschoolers' preacademic skills: self-regulation as a mediating mechanism

Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP improved low-income children's self-regulation skills (as indexed by attention/impulse control and executive function) from fall to spring of the Head Start year. Analyses also suggest significant benefits of CSRP for children's preacademic skills, as measured by vocabulary, letter-naming, and math skills. Partial support was found for improvement in children's self-regulation as a hypothesized mediator for children's gains in academic readiness. Implications for programs and policies that support young children's behavioral health and academic success are discussed.     

方法、情绪和态度——家庭教育中的矛盾心理探讨

现在的孩子学习压力挺大的,很多父母想给孩子疏解压力,但在放松的时候,又怕孩子学得少了,父母也是很矛盾的,学多了怕孩子累,特别是那些学习成绩比较好的孩子的父母,孩子玩多了又怕影响学习。     

保护孩子的自尊

家长当着外人批评孩子,是最伤孩子自尊、最令孩子反感的批评方式。某些家长视孩子为私有财产,认为老子教训儿子天经地义,父母的话是圣旨,孩子应当无条件地接受,不允许孩子有丝毫的反抗和不满。     

成长,从七十九分开始

儿子上学两个月后,迎来有生第一次考试。几天之后,他交给我一张语文试卷。卷面上方鲜红的79分不仅刺痛了我的眼,更刺痛了我的心。全班倒数啊!一直以来让全家人引以为自豪的儿子,曾经无数次赢得幼儿园老师交口称赞的儿子,居然第一次考试就给了我当头一棒!一时间,我好像傻了,什么也说不出来,眼睛呆呆地盯着试卷,心里却像打翻了五味瓶,说不清是一种什么滋味。几年来为了教育儿子付出的心血,难道就是这样的结果吗?妈妈,我考得不好。儿子的声音充满了无助,     

Stem cells in microfluidics

Microfluidic techniques have been recently developed for cell-based assays. In microfluidic systems, the objective is for these microenvironments to mimic in vivo surroundings. With advantageous characteristics such as optical transparency and the capability for automating protocols, different types of cells can be cultured, screened, and monitored in real time to systematically investigate their morphology and functions under well-controlled microenvironments in response to various stimuli. Recently, the study of stem cells using microfluidic platforms has attracted considerable interest. Even though stem cells have been studied extensively using bench-top systems, an understanding of their behavior in in vivo-like microenvironments which stimulate cell proliferation and differentiation is still lacking. In this paper, recent cell studies using microfluidic systems are first introduced. The various miniature systems for cell culture, sorting and isolation, and stimulation are then systematically reviewed. The main focus of this review is on papers published in recent years studying stem cells by using microfluidic technology. This review aims to provide experts in microfluidics an overview of various microfluidic systems for stem cell research.     

The impact of different types of physical activity on total and regional bone mineral density in young Brazilian athletes

Bone turnover is affected by exercise throughout the lifespan, especially during childhood and adolescence. The objective of this study was to investigate the impact of different sports on total and regional bone mineral density in male Brazilian adolescent athletes. Forty-six adolescents aged 10-18 years participated in the study: 12 swimmers, 10 tennis players, 10 soccer players, and 14 sedentary individuals. The athletes had engaged in physical activities for more than 10 h per week in the previous 6 months. Bone mineral density of the lumbar spine (L1-L4), left proximal femur region, and whole body was evaluated by dual-energy X-ray absorptiometry. Results showed higher mean values in the proximal femur region of tennis and soccer players (1.02 ± 0.18; 0.96 ± 0.16, respectively) than swimmers and controls (0.91 ± 0.14 and 0.87 ± 0.06, respectively) (P < 0.05). In relation to the impact of sporting activities based on bone age determination, we observed significant differences in bone mineral density at all evaluated sites at the end of puberty (16-18 years) compared with 10-12 years, with increases of 78% in the lumbar spine, 47% in the proximal femur, and 38% in the whole body.
