Phonological Awareness Skills in Young Boys with Duchenne Muscular Dystrophy

Substantial research has detailed the reading deficits experienced by children with Duchenne muscular dystrophy (DMD). Although phonological awareness (PA) is vital in reading development, little is known about PA in the DMD population. This pilot study describes the PA abilities of a group of five young children with DMD, comparing the results with those of a group of children with spinal muscular atrophy and with those of a group of typically developing children. The Preschool and Primary Inventory of Phonological Awareness was used to assess the PA skills of the participants. Results indicated that the children with DMD performed significantly poorer than the typically developing group on tests of Syllable Segmentation, Rhyme Awareness, Alliteration Awareness and Phoneme Isolation and significantly poorer than the spinal muscular atrophy group on Rhyme Awareness. The findings of this pilot study indicate that children with DMD may have an increased risk of having PA difficulties, thus requiring early PA training.

关于运动解剖学的几个基本概念

力和力矩是两个不同的概念，应加以区别使用；肌肉工作时定点的确定要以躯体支撑点为基本参考点，肌肉做静力性工作时是双固定状态；肌肉拉力线应用射线来标示；要根据具体情况作具体分析，不能简单地以动点向定点的连线标示，影响肌肉最大力量的解剖学因素是该肌肉内可能形成的最大横桥数目和肌肉收缩时的初长度，神经调节、肌拉力角、肌收缩矩均不是影响肌肉最大比力的解剖学因素．

三个连续的发现与用几何方法研究数论的新构想

在对毛比斯面的证明方法的深入研究中，发现了一种证明方法——“递推法”；在对“递推法”的进一步探索中，发现了一类新几何体——“棱环体”；在研究“棱环体”的边数的变化规律中，得到了一张“数表”，对“数表”的进一步研究，又相继发现了“最大公约数定理”、“素数规律”等．“棱环体”的发现，引发了“扭曲几何学”的构想；“数表”的发现，为一种新的数论研究方法——“数论的几何研究法”的提出，奠定了基础。

The one-in-ten: quantitative Critical Race Theory and the education of the ‘new (white) oppressed’

ABSTRACT

This paper challenges the notion that quantitative data – as a numeric truth – exist independent of a nation’s political and racial landscape. Utilising large-scale national attainment data, the analysis challenges the belief that ‘White working class’ children in England, especially boys, are ‘the new oppressed’ – as a former equality adviser has publicly claimed. The analysis applies Quantitative Critical Race Theory, or ‘QuantCrit’, an emerging quantitative sub-field of Critical Race Theory in education. The paper argues that far from being ‘oppressed’, White boys continue to enjoy achievement advantages over numerous minoritised groups; especially their peers of Black Caribbean ethnic origin. Additionally, the analysis uniquely exposes racialised trends of ‘equivalency’ in core subject qualifications, whereby minority ethnic children are over-represented in certain lower-status qualifications that are counted as equivalent in education statistics but not in the real world labour market. The analysis concludes that knowing misrepresentations of quantitative data are at the heart of an institutional process through which race and racism are produced, legitimised and perpetuated in education.     

Relating early childhood teachers’ working conditions and well-being to their turnover intentions

High turnover rates of early care and education teachers reduce the quality of education; unsatisfied teachers, suffering from stress or emotional exhaustion, are less equipped to promote children’s development and more likely to leave the classroom. We used data from a national survey of US early childhood educators (n?=?1129) to examine associations between teachers’ working conditions, well-being, and motivation with professional commitment and turnover intentions to move, leave, or remain. Multiple regression analyses revealed that more intrinsically motivated teachers were more likely to report intentions to move over leave, emotionally exhausted teachers were more likely to report intentions to leave, and lower teacher-reported working conditions predicted intentions to move or leave the field over staying. The results suggest that teachers’ well-being and perceived working conditions relate with their intentions to remain at their job or within the field and to their commitment to the profession.
