Fluid reasoning,working memory and planning ability in assessment of risk for mathematical difficulties

ABSTRACT

The demands on mathematical problem-solving have increased in almost all school systems internationally and may constitute a barrier for children with special educational needs (SEN). This study explored the role of fluid reasoning (FR), working memory (WM) and complex executive function of planning (EF) in children (N = 62) referred for assessment of SEN, and specifically of risk for mathematical difficulties (MD). Performances on FR, WM and complex EF of planning were used to predict risk for MD. Results showed that planning ability predicted children at risk for MD, beyond FR or WM ability, when comparing with children not at risk for MD. It was concluded that assessing the complex EF of planning in addition to FR and WM ability is crucial in identifying children at risk for MD. The importance of understanding how planning ability affects children’s mathematical problem-solving is discussed, in relation to assessment and teaching practices.     

Sexual Health Education in Massage Therapy Programs: A Survey of Program Directors

Massage therapy program directors completed an online survey to explore sexual education in massage therapy programs. The overall data suggest that program directors are supportive of sexual health education in the training of massage therapists and that such education is integrated into several aspects of their training programs. To enhance sexual health education, massage therapy programs could collaborate with specialists in sex therapy or sexuality education. Massage therapy training may need to include the following topics: working with clients who have been sexually abused, working with transsexual clients, understanding sexual arousal processes, and understanding dynamics between men and women.     

液固两相槽道流中柱状粒子取向的数值研究

对柱状粒子在槽道流场内的运动进行数值模拟，然后用统计方法得出大量柱状粒子的取向分布；给出了粒子长径比、粒子密度和流场区域对粒子取向分布的影响．计算结果表明，柱状粒子长径比的变化对粒子取向分布的影响不明显，粒子密度对粒子取向分布有一定影响，而流场区域所造成的流场横向速度梯度对粒子取向分布有重要影响．随着流场横向速度梯度增大，粒子取向趋势愈加明显，且当流场横向速度梯度增大到一定程度时，粒子取向都趋向于流动方向．文中部分结果与相关实验进行了比较，两者定性吻合较好。     

中国西部地区重力位能与板内变形动力

重力位能及其重力浮力是大陆板块内部重要的构造变形动力.中国西部地区构造变形以垂向抬升、横向拉伸和压缩为主要特点，其重力位能及重力浮力分布，深刻影响着西部板内变形动力学机制.地震学和重力学方法计算表明中国大陆西部蕴藏较大的重力位能，其中青藏高原重力位能在2×1012～7×1012N/m之间.地壳重力位能变化导致的重力浮力，是板内变形的主要构造力.在一定流变学条件下，重力位能足以产生青藏高原活动地区的构造形变.

Scratching and Turning Experiments on Machinability of Optical Glass SF6 in Diamond Cutting Process

To improve the machinability of optical glass and achieve optical parts with satisfied surface quality and dimensional accuracy, scratching experiments with increasing cutting depth were conducted on glass SF6 to evaluate the influence of cutting fluid properties on the machinability of glass. The sodium carbonate solution of 10.5% concentration was chosen as cutting fluid. Then the critical depths in scratching experiments with and without cutting fluid were examined. Based on this, turning experiments were carried out, and the surface quality of SF6 was assessed. Compared with the process of dry cutting, the main indexes of surface roughness decrease by over 70% totally. Experimental results indicated that the machinability of glass SF6 can be improved by using the sodium carbonate solution as cutting fluid.
