人类基因组计划(HGP)的提出及重大意义

人类基因组计划是一项庞大的科学工程。自1990年起，历经10年多时间，在诸多研究领域取得了显著进展和辉煌成就。目前，人类基因组计划业已成为探索人类生老病死生命奥秘的重大计划、成为征服人类顽疾有希望的计划、成为推动生物产业化发展的前沿计划。本文仅就人类基因组计划的提出和重大意义作以梗概阐述。     

教学管理的层次-灰色关联分析评价

在建立了教学管理评价指标体系的基础上,引入层次分析和灰色关联分析相结合的综合评价模型对教学管理进行评价,模型中利用层次分析法确定各评价指标的合理权重,应用灰色关联分析法对定性信息进行量化处理和比较,减少了主观因素的影响,提高了评价结论的准确性,为教学管理评价提供了一种新方法。     

B2B电子商务模式探讨

文章介绍了电子商务的几种主要模式及B2B电子商务概况，认为B2B模式将成为未来电子商务的主要模式。原因在于B2B模式具有使买卖双方信息交流低廉、快捷，可降低企业间的交易成本，减少企业的库存，缩短企业生产周期等竞争优势。同时还就B2B电子商务模式对企业的影响和制约我国B2B电子商务发展的因素及对策等问题进行了探讨。

A Process Approach to Community-Based Education: The People’s Free University of Saskatchewan

On the basis of insights provided by Whitehead and John Cobb, I show how the People’s Free University of Saskatchewan (PFU) is a working model of free, open, community-based education that embodies several characteristics of Whitehead’s philosophy of education. Formed in opposition to the growing commercialization at the original “people’s university,” (the University of Saskatchewan) the PFU has spawned distinctive ideals of its own. The PFU reflects Whitehead’s belief in the importance of shared knowledge fostered by community-based education, the value of abstract and practical knowledge, and the power of the imagination to establish a community of learners capable of acting freely together.     

用磁流变液实现导磁材料机件表面的光整加工

磁流变液是未来应用最广泛的智能材料之一,它在无外加磁场作用下表现出良好的流体特性,在强磁场的作用下它的粘度会在毫秒级的时间内增加两个数量级以上,表现出类似固体的特性,一旦去掉磁场又立刻恢复液体的特性.这种可逆、迅速、易控的特点使磁流变液在机械工程中得到广泛的应用,其中包括表面光整加工,如将其用于光学镜片的表面研磨.目前其加工对象仅限于非导磁性材料,而现在绝大多数的机械零件的材料为导磁性材料.文章明确了磁流变液光整加工方法的主要优点;根据加工机理分析和初步实验研究,概括出将磁流变液用于导磁性材料表面光整时碰到的具体问题,并有针对性地提出了合理的解决方法.     

美术欣赏教学的"五字法"

美术欣赏，是一种审美情感的教育，它既能提高学生的审美能力，又能培养学生的创造精神，这种独特的教育功能早已被一些专家、学论证，然而，采取什么样的方法才能更有效地发挥其功能和作用呢?本从五个方面对美术欣赏教学的形式和方法进行了研究探索。     

高职学生行业英语自主学习能力动态研究

通过问卷调查和访谈,对高职学生的行业英语自主学习能力展开了动态考察,并基于教师和环境两个因素探讨了其变化的归因情况。两次问卷数据对比显示,学生的行业英语自主学习能力存在提升的趋势,教师因素和环境因素对学生的自主学习有促进作用。访谈结果表明,教师教学理念和教学方法的更新以及自习环境和实践环境的建设有助于学生行业英语自主学习能力的提升,具体体现在行业英语学习兴趣的提高、自主学习意识的提升以及自我效能感的强化等方面。由此可见,教师合理有效的介入和理想的学习环境是促进学习者自主学习的必要条件。     

Educational Research for Policy and Practice in Japan – With Particular Reference to Youth Education

Based upon the Fundamental Law of Education, Japanese school education system has long been a source of pride for the country as a result of the high school participation rate, the homogeneity of compulsory education throughout the country. However, the confidence of the people in its schools is now showing severe signs of strain and fatigue. In recent years, there have been many reports about the growing seriousness of a number of educational problems having to do with young people in their childhood and adolescence. Since the mid-1970s, a number of problems have been highlighted. They include violent behavior, juvenile crimes, bullying, refusal to attend school, dropping out at secondary level of education, and corporal punishment. Against the above background, based on recommendations from such advisory bodies as the Central Council for Education and the National Commission on Education Reform, the Ministry of Education, Culture, Sports, Science, and Technology (MEXT) has adopted a range of policies and launched a series of educational reform programmes. For instance, what is called “Rainbow Plan”, based on the final report submitted by the National Commission on Education Reform, provides the country with basic guidelines for the educational reform in the near future. Roles of educational research for making policies have been of significance. Research initiated by the National Institute for Educational Policy Research (NIER) and the National Federation of Educational Policy Research Institutes (NFERI) is an example of contributions to the development of educational qualities in the country. This revised version was published online in July 2006 with corrections to the Cover Date.     

Optical encryption with cascaded fractional wavelet transforms

INTRODUCTION Recently, with the development of science andtechnology, more and more people become interestedin researching image encryption techniques. Manymethods have been proposed for optical image en-cryption. Random phase encoding methods and digi-tal holography techniques are effectively used inencrypting (Javidi and Nomura, 2000; Unnikrishnanet al., 2000a; Hennelly and Sheridan, 2003; Nishchalet al., 2004). Meantime some important properties oflight are used to realize encryptio…
