一个体现新课程理念的教学内容设计——“圆锥曲线第二定义”的教学体会

新课程实验教材已完成了一轮教学．由于新课程的理念变了，编写意图也发生了变化，新教材相对于与原教材而言，内容变了、体系改了、要求不同了、方法更新了．因此，在教学中新旧理念互为碰撞、教学方法多有调整、内容处理各有不同．于是，教师如何更好地领会编写者的意图，体现新课程的理念，使学生得到全面发展是需要教师在教学中经常思考和密切注意的问题．

Community operational research issues and public art practice: the art director system

The key issues of community operational research, outlined in a paper by Ritchie, have relevance to community projects in general and, we argue, a particular relevance to public art. We illustrate this relevance by describing eight case studies in public art, four in Japan and four in the west, and by considering the projects in a three-way factorial design, make a case for the art director system in the management of public art projects.     

The geometry of African art II. A catalog of Benin patterns

This paper investigates the repeated patterns found in the art of Benin, classifying them on the basis of the 24 plane crystallographic groups. Although the patterns are less varied than in Bakuba art, studied in an earlier paper [1971], the same number, 19, of types occurs. Drawings of each are given, including many examples of each of the seven “one-dimensional” types.

‘Seeing is believing’ and ‘believing is seeing’

The principal concern of my paper is a distinction between two ways of appreciating works of art, characterised here in terms of the phrases ‘seeing is believing’ and ‘believing is seeing’. I examine this distinction in the light of an epistemological requirement at times at least grounded in what David Davies, in his Art as Performance, refers to as the ‘common sense theory of art appreciation’ in order to assess exactly what aspect of the philosophical approach generally known as aesthetic empiricism his account commits him to reject. I argue that the ‘experiential requirement’, if only conceived in a slightly broader way than is usual, might very well have an important role to play not only in the appropriate appreciation of works that do not demonstrate the need for such a requirement (primarily works of late modern and conceptual art), but also in the ontological account Davies himself favours.     

Two comments and a problem for David Davies’ performance theory

This paper considers the view, recently put forward by David Davies in Art and Performance, that works of art should be identified with the generative performances that result in the object, rather than with the object. It attempts to disarm two of Davies arguments by, first, providing a criterion by which the contextualist can accommodate all and only the relevant generative properties as properties of the work, and, second, providing an alternative explanation for his modal intuitions. Finally, it draws attention to Davies’ difficulties in providing a clear criterion for the identity of the work of art.     

DEA meets Picasso: The impact of auction houses on the hammer price

Employing a hedonic price approach within a framework of central tendencies no conclusive results about the impact of auction houses on final prices of art objects have been found. In order to focus on auction houses as a unit we have applied a benchmarking technique, DEA, developed for efficiency studies. New performance indicators are developed and calculated giving an insight into auction house differences impossible to obtain using hedonic price approach. The performance indicators may also be regarded as quality indicators assuming perfect arbitrage leads to the same unobservable quality of art object obtaining the same price.

All' art. 7, applicando due idendità relative alle somme delle potenze simili delle radici dei polinom? simmetrici e ai coefficienti di tali polinom?, si stabiliscono per le funzioni simmetriche elementari e somme di potenze simili digrado dispari qualunque delle congruenze che perfezionano quelle dell'art. 6.
