International Early Childhood Resources from Educational Research Abstracts (ERA)

The aim was to examine cross-cultural variation in linguistic responsiveness to young children in 10 English-speaking mother–child dyads and 10 Italian-speaking mother– child dyads. All 20 children were late talkers who possessed delays in expressive vocabulary development but age-appropriate cognitive and receptive language skills. Dyads were filmed in 15 minute free play contexts, which were transcribed and coded for measures of maternal linguistic input (e.g. rate, MLU, labels, expansions) and child language productivity (e.g. utterances, different words used). The results revealed that the Italian mothers used more utterances, spoke more quickly and used a more diverse vocabulary than the Canadian mothers. The Italian children mirrored their mothers and also used more utterances and a more diverse vocabulary than the Canadian children. Mothers in both groups used similar percentages of responsive labels and expansions. However, Italian mothers responded to fewer of their children's vocalisations, using a smaller percentage of imitations and interpretations than the Canadian mothers. Correlations between maternal input and children's language productivity revealed that contingent language measures (e.g. imitations, interpretations, expansions) were related to high levels of productivity in children in both cultural groups. The results support the use of language interventions based on increasing maternal responsiveness for these children at the one-word stage of language development. They also point to differences that may be culturally based. For example, Italian mothers use faster rates of interaction and appear to have higher expectations for their children's verbal participation in interaction. This is reflected in higher rates of language production from their children, even though children in both cultural groups have similar vocabulary sizes.

竞技体育可持续发展的评价指标及其人力资源研究

竞技体育可持续发展是新世纪我国体育界面临的重大课题。笔者以 4省 44 2人为调查对象 ,研究和探讨了竞技体育可持续发展的评价指标 ,经因子分析和专业理论研究 ,建立了 5类共 15项指标 :科技道德教育类、体制规范类、经济竞技发展类、外部投入类和消除“近亲繁殖”的教练员培养制度类。笔者在研究中发现 ,我国无论是体育还是非体育家庭都不愿意孩子从事体育和竞技体育 ,主要原因有传统思想问题、体育的社会地位问题、运动员的教育问题等 ,其中教练员的“近亲繁殖”培养制度是影响我国竞技体育人才资源的最主要的原因之一。
