How can children with mild literacy difficulties be supported at the transition to secondary school? A small‐scale quasi‐experimental study

There is evidence that pupils with weak literacy skills struggle on transition to secondary school. Many experience a drop in attainment in the summer break between the two. A British government‐funded programme of rigorously designed research on boosting literacy at transition had (by 2015) found only four of 15 interventions evaluated had positive effects. This small‐scale quasi‐experimental study investigated the effectiveness of support for pupils with mild literacy difficulties on transition to secondary school. Thirty‐two pupils in three schools were involved; half received the programme. Pairs were matched on reading, spelling, age and gender. Intervention was designed around the individual needs of each pupil, focusing variously on language skills, writing, reading and spelling. The group receiving the programme made modest gains in spelling, reading efficiency and single word reading. The comparison group lost ground, relatively, in all three areas. The results suggest a promising line for more rigorous investigation.

温州与苏州制度变迁的比较研究--基于人力资本结构的实证分析

温州和苏州代表了两种不同区域经济发展模式，其不同的制度变迁很大程度上取决于它们所具有的不同的人力资本结构。中国改革初期，温州企业家人力资本富裕导致了诱致性制度变迁；而苏州由于企业家人力资本缺乏，选择了强制性制度变迁。     

非晶团簇Au19的熔化特征研究

介绍了分子动力学的基本原理和计算过程,模拟了Au19团簇从类固相到类液相的相变过程.将所得的数据绘制成图线,并进行了分析与讨论,结果发现Au19这种不规则的非晶团簇的熔化过程是分步完成的:首先是外层某些不稳定原子开始熔化,其次是其他外层原子也随能量的升高熔化,最后是随能量的不断升高,中心原子也完成了熔化过程,整个体系完成从类固相到类液相的相变过程.由此可以看出,Au19的熔化过程是分步完成的,有别于晶体团簇和其他结构规则的非晶团簇,是一个比较特殊的过程.
