Oseen流动中粘性对自由表面波的影响

Based on the complex dispersion relation for the two-dimensional free-surface waves generated by a moving body in the steady Oseen flows, the effect of viscosity on wavelength and wave amplitude was investigated by means of an asymptotic method and a numerical analysis. A comparison between the asymptotic and numerical analysis for the viscous decay factor demonstrates the validity of the perturbation expansions for the wave profile. The numerical result shows that the wavelength of viscous wave is slightly elongated in comparison with that of inviscid wave.     

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.     

Different children’s perspectives on their learning environment

This article reports and discusses findings from an ethnographic case study, aiming to gain a deeper understanding of how different children perceive their learning environment in the first grade of primary school, with regard to social as well as academic aspects. The theoretical framework is based on an interactional perspective, where children’s learning and development are considered to take place in a dynamic and ecological system. The reported results are based on interviews with 16 children, and observed teaching situations during the first year of primary school. Research among children demands special ethical considerations, such as how to avoid questions and interest from the researcher affecting the position of children being vulnerable in some way. The findings show that, within a group of children, facing a similar learning environment, there are significant differences between the experiences expressed. The findings presented support the importance of listening to children when planning educational settings. Listening to and taking into account the children’s different voices is an essential part of research and education that strives for inclusion, learning and well-being of all children.     

从《林纾的翻译》看翻译的可译性与不可译性

通过对著名翻译家钱钟书先生《林纾的翻译》一文的研究,从中看到钱先生对翻译研究的第一哲学性问题——可译与不可译的论说有非常独到的见解和阐释。钱先生通过对林纾翻译作品的评论,把翻译的指导原则和翻译技法通过"诱"、"媒"、"讹"、"化"等极有概括力的字一一体现出来,充分体现了文学作品可译与不可译之间的辨证关系。其思想对我们从事翻译理论的研究和翻译实践的操作都具有重要的指导价值。     

如何开展大学生思想政治教育

随着社会生活的现代化进程及建立社会主义市场经济体制带来的深刻社会变革,大学生的价值观念、思维方式、人际关系等都发生了很大变化。在这样复杂的社会环境中,更是要加强对大学生的思想政治教育,使大学生成长为中国特色社会主义事业的合格建设者和可靠接班人。     

阿尔兹海默症患者的语义记忆损伤:表现、理论及展望

图片命名、范畴流畅性等神经心理学测验表明,阿尔兹海默症(AD)患者普遍存在语义记忆的损伤,并随着病程的发展表现出进行性与弥散性特点。AD患者语义记忆的损伤既可能由语义知识的存储障碍造成,也可能由语义知识的提取障碍引发,还可能由存储与提取的双重损伤造成。未来研究应开发出对早期AD检测更为敏感的语义记忆测验,并采用横向与纵向多种研究技术与手段,考虑不同语言文化背景下AD患者语义损伤的情况,以综合分析AD患者语义记忆损伤的实质及其发展趋势。

The cooking teacher: investigating gender stereotypes in a Korean kindergarten

This article discusses some findings from a small‐scale investigation of children's gendered beliefs and behaviours in a Korean kindergarten which was attempting to challenge gender stereotyping through the anti‐bias intervention of a ‘cooking curriculum’. A sample of 14 children, some with ‘working’ mothers and some with ‘housewife’ mothers, was observed for two months, and informally interviewed on several occasions. The children's mothers were also interviewed. The findings are situated in the context of the changing, but still traditional, culture of Korean society, as well as in the contexts of early childhood education and theories of gender acquisition. They confirm that, although children are highly likely to reproduce the beliefs current in their home environment, they are open to reconstructing these views when actively challenged to consider alternatives, either by the school curriculum or by engaging in debate with a researcher or practitioner. The nature of the ‘alternative’ views available may however be problematic.     

磁共振安全教育在科研扫描人员中的实施与评估

磁共振安全包括受检者安全及设备安全,重庆医科大学附属第一医院放射科团队通过对进行磁共振科研扫描的人员实施标准化的磁共振安全教育,包括课上部分(理论知识、现实案例展示)和课下部分(磁共振岗位实习),可以保障受检者及设备的安全,保证科研扫描工作的顺利进行。不足之处有:科研扫描人员仅能进行基本的科研扫描,而且一旦出现危及受检者安全或设备安全的情况,容易引起纠纷。
