2～3岁幼儿自我概念教师评定量表的编制

依据美国幼儿自我概念课程，结合中国文化及幼儿发展的特点和现状。以幼儿自我概念的结构和幼儿自我概念发展的年龄特征、性别差异为基础，编制了一套2～3岁幼儿自我概念教师评定量表。并选取长沙市电信幼儿园共印名幼儿作为被试进行测试，对此量表进行信度、效度检验，结果证明量表有效、可信。     

我国高等学校规模计量方法与应用新探

教育规模已有一些计量方法。通过考察师生比模型的边际率可以得到新的计量方法。它不但为我们考察高等学校的合适规模提供了思路和方法，也能解释当前扩招的一些问题。     

Social‐emotional well‐being and resilience of children in early childhood settings – PERIK: an empirically based observation scale for practitioners

Compared with the traditional focus on developmental problems, research on positive development is relatively new. Empirical research in children's well‐being has been scarce. The aim of this study was to develop a theoretically and empirically based instrument for practitioners to observe and assess preschool children's well‐being in early childhood settings. The analysis of preschool teachers' ratings yields six dimensions of social‐emotional well‐being: (1) making contact/social performance, (2) self control/thoughtfulness, (3) self‐assertiveness, (4) emotional stability/coping with stress, (5) task orientation, (6) pleasure in exploration. Composite scales were constructed. PERIK consists of six scales of six items each. The scales differentiate in both the upper and lower range and despite their brevity have good psychometric qualities. The instrument was published together with a booklet containing examples of how PERIK observations can be employed in practical work with children.     

浅谈“两个尺度”的问题

马克思关于“美的规律”的提法是马克思美学理论中的一段极为重要的论述,然而对于其中“内在的尺度”究属谁的尺度却众说纷纭,本从比较各家译入手,指出问题的症结在于中译词和德原词义不完全对等上,根据中译词词义,则理解为“物种的尺度”和“人的尺度”均无不可,但根据德词义的特定含义,则“内在尺度”只能理解为“物种的尺度”。     

一种新型的闭环真空硅微陀螺仪(英文)

提出了一种新型的硅微陀螺仪闭环控制策略.所设计的硅微陀螺仪工作在10 Pa,采用金属壳CAN封装形式,驱动和检测两模态品质因素高达10000以上,且都采用了基于静电力反馈方法实现闭环.驱动模态采用单边驱动单边检测,尽量使线路简化;检测模态采用双重分解和重构闭环回路.测试结果表明:有用信号和正交信号实现很好的相位解耦,互不影响;在满量程4-300(°)/s、标度因素9.6 mV/((°)·S)的情况下,零偏稳定性已达到28(°)/h;非线性度达到400×10-6;仿真带宽大于100 Hz.这较以前设计的仅在空气下工作的硅微陀螺性能提高了近2个数量级.

Mathematics: a female,male or gender‐neutral domain? A study of attitudes among students at secondary level

The aim of the current study is to investigate whether Swedish secondary school students perceive mathematics as a female, male or gender‐neutral domain. A sample of 1300 students in two age groups, 15‐ and 17‐ years, answered a questionnaire and about 50 students participated in interviews. The main part of the inquiry form consists of Who and mathematics, an attitude scale recently developed by other researchers. The results are analysed with respect to gender, school year and study programme. Gendered attitudes were found among considerable minorities. There is a marked tendency to view mathematics as a symbolically male domain: positive aspects are associated with boys and negative aspects perceived as more female. Older students hold more strongly gendered views than younger. Boys in the science programme have the strongest beliefs of mathematics as a male domain.     

资产质量评价探析

资产质量之优劣,对企业资产运营效率、经营成果等多方面都有较大影响.准确评价企业资产质量,可以使企业了解资产在配置、管理和耗费等方面的现状.一般而言,评价企业资产质量可以从以下五个方面来进行.即:资产规模的适应性、结构的均衡性、流动性、盈利性、安全性.同时在资产质量评价的过程中,应该注意资产评价的原则、各要素之间的内在联系及资产的成长性三个方面的问题.     

大型循环流化床环形炉膛中气固流动特性的CPFD数值模拟

环形炉膛理论上可有效解决大型循环流化床中二次风穿透不足的问题,其内外环壁面的设计也为更多的受热面提供了充足的空间,是一个具有明显优势的新型炉膛结构.本文使用CPFD数值模拟方法,对循环流化床环形炉膛冷态实验台内气固流动特性进行研究.模拟得到的炉内轴向压力分布和返料流率均与实验结果吻合较好.在此基础上分析炉内气固流动特性以及炉膛出口气固流动不均匀性,研究结果为环形炉膛的设计优化提供有价值的信息.
