经济的发展并不一定导致幸福的增加--对"和谐社会"的思考

长期以来,我们一直把经济发展与人民福利的提高看作是一种正相关关系,其实,物质条件的改善只是促进福利增长的一个重要条件,甚至不是必要条件,更不是充分条件.从经济增长与幸福之间的关系来看,只有促进社会的全面发展,才能真正做到以人为本,提高人民的福利水平.     

独具特色的麦积山石窟

麦积山石窟是中国古代四大石窟之一。石窟艺术源自古代印度文化,在中国及世界各地有着许多古代石窟艺术的历史遗存,而在众多的石窟艺术的历史遗存中,麦积山石窟有着许多不可替代的惟一性。和国内外比较著名的石窟相比较,麦积山石窟在人文环境、地理风貌和佛教造像风格等方面的独特性就会突现出来,这正是麦积山石窟的价值和魅力所在。     

Seeking Nettle Textiles – Utilizing a Combination of Microscopic Methods for Fibre Identification

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history.

普通高中基层弹性教研组织的建构

普通高中基层教研组织是学校的基本单位,是教师成长、发展、互动的群体。尽管传统教研组织在“教师职业化”方面意义深远,但其在现实中过于彰显科层性管理功能:只涉及问题的解决,而不注重问题的发现和问题的界定;高扬的“工具理性”阻碍了“教师职能的专业化”的发展。面对走向“专业化的教师职业”问题,本研究认为:对教研组的研究和改型变得十分必要;构建一个弹性教研组织作为教师反思、批判和发展的平台已势在必行。
