Operating systems

The objectives and stages of operating systems introduced in Part 1 are continued here. Four major components —process management, input-output (I/O) device management, memory management, file management and protection are discussed.     

School quality, child wellbeing and parents’ satisfaction

Child wellbeing at school and enjoyment of the learning environment are important economic outcomes, in particular because a growing body of research shows they are strongly linked to later educational attainments and labour market success. However, the standard working assumption in the economics of education is that parents choose schools on the basis of test-score performance, and concerns about child happiness are largely ignored. In this paper, we address this omission and investigate to what extent parents’ and children's views of their school are linked to test-score based performance, and to what extent parents’ judgements of school quality are linked to their child's happiness. To do so, we use information on stated attitudes from the Longitudinal Survey of Young People in England (LSYPE) matched to administrative records on pupil achievements in England. Our results suggest that test-score based measures of school quality tend to dominate parental satisfaction with the learning environment. However, school quality along this dimension is not strongly associated with pupil happiness and wellbeing at school.

教学环境对于学生的学业成就和智力发展有着至关重要的影响。教学环境可分为教育环境与学习环境。本文将从教育心理学针对教学环境的新进展入手,探讨教育环境、教学环境对学生学业成就、学业自我概念的影响,以针对课堂情感氛围和Marsh的I＼E模型与大鱼小池效应的组合模型为重点,探讨其对于教与学的启示。     

浅谈数学教学的“生活味儿”

让数学走进生活是新课标的要求。让课堂生活化,引导学生在生活情境中感受数学,体验数学源于生活的真正含义,对提高数学教学效果具有事半功倍的作用。但同时切忌把数学生活化片面理解,而从一个极端走向另一个极端。

《庄子》二题

庄子的“吾丧我”涵盖工夫与本体两个层面,其含义是“唯丧我才能见道”,又是“见道后的自然解脱”。庄子“大木”的形象是丑的,但“大木”意象是美的,“大木”的本质是庄子对个体生死意义的独到领悟,又是一种超然而可求的人生态度。     

美国产学研协同创新联盟建设与经验——以I/UCRC模式为例

源于20世纪70年代的"产业/大学合作研究中心"现已发展成为美国最典型的产学研协同创新模式,并拓展为"州/产业/大学合作研究中心"模式。"产业/大学合作研究中心"协同创新模式在组织构成、组织管理和协同创新项目设计上都具有其明显优势,并在其长期发展中积累了丰富经验,这对我国产学研协同创新联盟建设具有重要借鉴价值。     

课程建设与教材建设相结合对精神医学专业发展的促进效果研究

课程与教材建设是高校专业建设重要重要内容,如何有效发挥两者的协调促进作用是高等教育工作中的一项重要任务,精神医学专业在建设发展过程中以课程建设为基础,科学引导教材建设内容和方向,并以教材建设为篮板,促进课程体系改革和教学方法的完善,经多年的实践,我院的精神医学专业得到了蓬勃发展,为我国精神卫生事业的进步做出了积极的贡献.     

投掷运动员体成分的调查分析

通过对受试者体成分皮褶厚度的测定,并对其派生指标的比较发现：投掷选手皮脂较厚,其中重器械投掷选手达到肥胖标准。分析认为,这是由于其肌肉体积逐渐增大的同时,总伴随着皮下脂肪逐渐堆积的结果。肥胖不仅影响运动的效果,对身体健康也不利。建议投掷选手在促使肌肉体积增大的同时应积极采取消除脂肪的措施。
