民族文化原传介质与艺术传播

传播作为人与人、人与群体、群体与群体之间的社会信息交往，很大程度上也是一种文化传播。民族文化本身通过一定的介质传播，而民族文化传播原传介质本身也就是一种文化，换句话说，民族文化原传介质本身就是民族文化存储器。文章通过云南少数民族留存下来的壁画、剪纸、乐舞等分析，指出其民族文化的艺术传播，以及艺术传播中对民族文化的保留，民族文化原传播介质以及“活形态”的存在，以及这些对研究民族文化的重要意义。     

On Technology

The basic premise of this paper is that the problem of technology is not a technological one, but one of understanding and vision. The entire Western tradition, in its religious as well as its secular modes, has always admired technique. True, the modern age has increased the mechanization of technology, and more recent technological advances have extended our sensory modes of knowing, tempting us to fall in love with them much as Narcissus fell in love with his own reflection. However, there is nothing necessary in these developments or in the views spawned by them.Technology encompasses the instrumentalities with which we create the made world. The made world, not unlike the natural one manifests Being; it is the unconcealment of reality's potential to be made. It is up to us to understand technology in this way and not as the mere manufacture and use of tools.Education is the main means at our disposal to create a new vision of technology and a new yoga to yoke ourselves to Being. The goal is to learn to see technology as an aniconic symbol of Being.     

正义视野下的中小股东权益保护

正义是法律的终极价值,也是公司法的终极价值目标。正义价值要求公司法在促进公司效率的提高和大股东利益最大化的同时。妥切保护中小股东权益。而正确处理公平与效率的关系是实现中小股东权益保护的前提。当下，我国公司法应该更加重视公平，不仅要把公平置于信仰层次，而且要更多地把公平和效率同样地置于操作层面。要通过合理的制度安排，完善公司的治理结构。切实维护中小股东权益以实现社会正义。

Understanding the role of learning and teaching support materials in enabling learning for all

There are many assumptions about the ways in which textbooks and other learning and teaching support materials (LTSM) can contribute to improved learning outcomes in many international contexts. These can focus on ways that they can implement the school curriculum, often in lieu of good pedagogical practice. Drawing on case studies from Rwanda and South Africa, the complexity of the role of LTSM as part of classroom enactment is shown. The discussion suggests that there are enabling factors to this including support for teachers’ use of LTSM and the availability of materials to all learners. A framework is presented in which LTSM, teachers and learners can become equal partners in teaching and learning, but only when adequate language and other pedagogical support structures are provided. Conclusions consider the potential impact for LTSM use when it is elevated to a medium that is accessible and useful to both teachers and learners.     

流体媒质界面上半波损失问题的讨论

本文主要是利用流体媒质界面处速度和能流的连续性边界条件,定量地分析,研究弹性纵波在界面处的半波损失问题。通过分析、研究,得出了弹性纵波有无半波损失的正确判据,及“入射波由波阻小的媒质射入波阻大的媒质,界面处反射波存在半波损失”不是普遍成立的结论。
