我国体育教育的功能性缺失及其根源探究

体育教育是学校教育中不可或缺的一部分,它的缺失不仅是学校教育功能缺失的表现,更是表明我们在人才培养方面机能的缺失.面对当前体育教育缺失越来越严重的现状,本文在运用文献资料法、实证法、逻辑分析法的基础上分析了我国体育教育功能演变的特点,探讨了其功能性缺失表现的内容,深挖了其功能性缺失的根源,并进而提出了体育教育功能运行的保障措施,以期达到促进我国体育教育功能的有效发挥.     

New mode of universal access and Global Memory Net

INTRODUCTION During 1998~2002, I was privileged to serve as a member of the US President’s Information Technol- ogy Advisory Committee (PITAC), and all members were deeply involved in the drafting of several PITAC Reports to the President. The one related to digital libraries was the 2001 Report of the PITAC Digital Library Panel, entitled Digital Libraries: Universal Access to Human Knowledge (PITAC, 2001). It offers an ambitious vision: “All citizens anywhere anytime c…     

行政体制缺陷与农民负担

农民负担形式上源于税收、提留和社会、劳务负担，县久减不下，根源于行政体制的缺陷。主要表现在：行政职能的“全能主义”及利益化趋势；行政决策体制程序的不完善；行政执行的简单化与异化；人事行政编制的法制化滞后；行政监督不力。落实农民减负政策，要从以往的技术层面研究转向制度层面改革与设计。     

建构城市记忆——城市公共档案馆编研功能拓展初探

从某种意义上讲,档案编研的过程就是编研人员依据一定的价值标准和原则,从档案馆藏中筛选"原料",建构城市记忆的过程.以建构城市记忆为价值取向的档案编研工作应当遵循集体性、原真性、整体性和系统性的编研原则.     

Suitability of school textbooks for 5 to 7 year old children with colour vision deficiencies

Purpose

The aim of the present study was to determine, through colorimetric analysis, whether school textbooks for children aged 5 to 7 years contained tasks requiring normal colour vision discrimination for their resolution. In addition, the performance of a group of observers with diverse colour vision deficiencies was evaluated while conducting the tasks under analysis.

Results

Textbooks of mathematics were found to include 10% of tasks which, to an observer with colour vision deficiency, would be very difficult or impossible to solve. The level of difficulty of each task was influenced by the type and degree of colour vision deficiency and by the actual ambient illumination under which it was observed.

Conclusions

Some school textbooks need to be redesigned through an alternative use of colours and textures to take into consideration colour vision deficiencies. In view of the present findings, many Spanish editorial boards have committed to undertake these changes.     

超个人心理学的人性研究及其启示

从构造主义、行为主义到精神分析,主流心理学在理解人的高级心理现象时,显得贫乏和无力,面对现代人道德迷失、生命失重,主流心理学难以回答。在人本主义心理学基础上发展起来的超个人心理学,超出了人本主义以自我为中心对人性的狭隘理解,把对人性的理解带到一种宏大的范围,弥补和校正了传统心理学之不足,并整合了其有价值的东西。使得被主流心理学所抛弃的,但对个人的发展至关重要的信念和价值观,又重新受到了心理学的关注。笔者通过对主流心理学、超个人心理学研究的反思,得出如下启示:(1)心理学对人性研究和理解应遵循下列模式:最消极的一面-消极的一面-中性的一面-健康高级的一面-超个人的一面(最健康高级的一面),(2)心理学对人性的研究应融合东西方人性观。(3)超个人心理学忽视了人性中恶的一面,属于理想主义人性观。     

Effect of iron deficiency on developing rat brain

Iron deficiency evolves, slowly through several stages. Early iron deficiency caused a depletion in iron stores as shown by a reduction in the levels of hepatic non heme iron (44%) in the 7 days old pups born to iron deficient mothers. The hemoglobin levels and PCV (packed cell volume) were significantly reduced only after the age of three weeks. The activities of GABA (γ-amino butyric acid) shunt enzymes viz. GDH, GAD and GABA-T (glutamate dehydrogenase, glutamate decarboxylase and GABA-transaminase, respectively) and GABA content were found to decrease during gestation and/or lactation iron deficiency at 1 week (wk), 2wk, 3wk and 4wk of age in the developing rat brains. However GABA binding showed a significant increase at different age groups. The iron deficiency during lactational exposure showed significant alteration in most of the parameters only at the age of 3 weeks onwards. On rehabilitation with iron supplemented diet for 2 weeks, these altered parameters could not attain corresponding control values. A prolonged iron deficiency causing alterations in GABA may lead to neurological and behavioral alterations.     

儿童认知发展中的利用缺陷研究

首先介绍了儿童认知发展中利用缺陷的定义,然后通过对前人的研究文献的分析说明了利用缺陷存在的证据和儿童利用缺陷的发展特征。并从个体可获得的心理资源、背景知识、元记忆、对先前无效策略的抑制和包括智商、性别、温度、动机等的非发展性原因来揭示利用缺陷的影响因素。最后展望了将来可能研究的几个重要问题并简单的说明了利用缺陷对于我们教育的启示。     

世界幼教事业发展趋势:国家财政支持幼儿教育

国家财政支持幼儿教育已成为一个世界性的发展趋势。这一趋势的出现基于对幼儿教育重要性的认识、有关幼儿教育的正外部效益的发现和对幼教市场缺陷的揭示。幼儿教育经费整体投入不足、有限资源分配不公、效益不高是我国幼儿教育财政投入体制的主要问题,必须从制度和政策层面加以改进。
