只谈风月怎么行--评《风月无边》兼论当代影坛、剧坛创作的"缺钙"现象

刘锦云的《风月无边》创下了票房记录,但在这喧嚣的商业运作背后,却是骨质戏剧精神的缺失和商业泡沫下的巨大文化虚空,这种现象,和当今影坛、剧坛的"缺钙"现象一脉相承。在现代都市人甚嚣尘上的弱化和虚浮里,只谈"风月"的雅致怎能撑起他们贫瘠而暗涩的精神家园?     

情报检索语言与主题网关

论文以主题网关的典范——英国社会科学主题网关(SOSIG)为例，分析了主题网关利用情报检索语言的做法，包括对分类语言、主题语言和自然语言的利用。最后得出情报检索语言在网络环境中仍然可以发挥信息组织的有效作用；同时为了更好地适应网络环境，应当对情报检索语言进行必要的改造。

论当前环境伦理学教材建设中的理论硬伤

环境伦理学是一门属于哲学范畴的新兴科学,对其研究对象及诸多理论问题,在认识上,国内外还存在着相当大的分歧,尤其是对关键的研究对象、学科的社会特性和人们争论较大的自然价值及三个"中心论"问题等方面,造成了严重妨碍学科本身发展的硬伤.     

How teachers perceive the new curriculum reform: Lessons from a school district in the Eastern Cape Province, South Africa

The meanings that a teacher attaches to the new curriculum reforms act as his or her map on the curriculum implementation journey, and these usually determine the success of the education reforms. This research article explores the meanings attached to the new Science curriculum reforms by primary school teachers in a school district in South Africa, where the perceived meanings emanated from, as well as the role they played in the implementation of the reforms in the classroom. It is argued that new curriculum reforms have to take place concurrently with other changes in order for them to have a significant and long-lasting effect. Three possible ways will be suggested that will help the teachers to avoid formulating reform meanings that are not aligned with the vision and goals of the new curriculum.     

The challenge of involvement in reflective teaching: Three case studies from a teacher education project on conducting classroom discussions on socio-scientific issues

The purpose of this qualitative study was to learn more about how teachers deal with a reflective teaching approach aimed at developing their competencies in analysing and facilitating classroom discussions on socio-scientific issues. Three cases of teachers' journeys through the project are reconstructed and characterised. We posit that each teacher benefited from the project according to his or her individual situation, needs and learning style. A number of modifications to the project design are proposed and can be summarised by the idea of assisting teachers more closely and more individually as they pass through the reflective teaching process.     

Free vibration of pre-tensioned nanobeams based on nonlocal stress theory

The transverse free vibration of nanobeams subjected to an initial axial tension based on nonlocal stress theory is presented. It considers the effects of nonlocal stress field on the natural frequencies and vibration modes. The effects of a small scale parameter at molecular level unavailable in classical macro-beams are investigated for three different types of boundary conditions： simple supports, clamped supports and elastically-constrained supports. Analytical solutions for transverse deforma- tion and vibration modes are derived. Through numerical examples, effects of the dimensionless nanoscale parameter and pre-tension on natural frequencies are presented and discussed.     

论韩非《解老》《喻老》道论之特点

韩非的"道"在老子的"道"的基础上,降低了两个层面,使老子的"道"的"博大"、"玄远"、"形上"、"神秘"等色彩统统退去了。韩非就是这样改造降格,将老子的"道"纳入了自己的政治哲学,并为其服务。

Lung ventilation functional monitoring based on electrical impedance tomography

Medically,electrical impedance tomography(EIT)is a relatively inexpensive,safe,non-invasive and portable technique compared with computerized tomography(CT)and magnetic resonance imaging(MRI).In this paper,EIT_TJU_Ⅱ system is developed including both the data collection system and image reconstruction algorithm.The testing approach of the system performance,including spatial resolution and sensitivity,is described through brine tank experiments.The images of the thorax physical model verify that the system can reconstruct the interior resistivity distribution.Finally,the lung ventilation functional monitoring in vivo is realized by EIT,and the visualized images indicate that the configuration and performance of EIT_TJU_Ⅱ system are feasible and EIT is a promising technique in clinical monitoring application.
