A Study on Comprehensibility of Concept Descriptions
No full textA transformation of descriptions of concepts without a change of meaning makes sense under a heterogeneous space of concepts, like Explanation-Based Learning (EBL) under the operational criterion. Under finite awareness the heterogeneousness is necessary, because agents have to select certain finite sets of concepts under criterion. Comprehensibility seems to come from the finite awareness, and it should be realized by such a transformation of descriptions. In this paper, we discuss comprehensibility of descriptions using a formalism of first order logic with finite awareness, and a couple of characterisations. Methods to transform descriptions in a sense of goodness discussed in the paper. The address is temporary. After March 1996, author's address will be: Department of Intelligence and Computer Science, Nagoya Institute of Technology, Gokiso-cho, Showa-ku, Nagoya 466, Japan.

No full textRelative invariants of 2-simple prehomogeneous vector spaces of type I
No full textAbstractIn the present paper, by using equivariant maps, we construct explicitly relative invariants of the 2-simple prehomogeneous vector spaces of type I, which are classified in [T. Kimura, S. Kasai, M. Inuzuka, O. Yasukura, A classification of 2-simple prehomogeneous vector spaces of type I, J. Algebra 114 (1988) 369–400]. This is a continuation of our previous work [T. Kogiso, G. Miyabe, M. Kobayashi, T. Kimura, Non-regular 2-simple prehomogeneous vector spaces of type I and their relative invariants, J. Algebra 251 (2002) 27–69; T. Kogiso, G. Miyabe, M. Kobayashi, T. Kimura, Relative invariants of some 2-simple prehomogeneous vector spaces, Math. Comp. 72 (2003) 865–889]
Roberto Verganti, Design-driven Innovation（ Harvard Business Press, 2009）
No full text 本論は，Verganti, R.によって書かれた「デザイン・ドリブン・イノベーション」を批判的にレビューしたものである。著者が考える同著の主な問題点は，その稚拙な論理構成と実証的事実の乏しさにある。本論では，同コンセプトを安易に信用することの危険性を反事例を導入しながら説明し，経営学書を読む際の論理的思考の重要性を主張する。This is a paper which critically reviewed the book,“Design-driven Innovation,”authored by Verganti, R. The main problem of this book which the author thinks exists in its poor logic and a lack of empirical findings. This paper explains the risk of believing this concept easily by introducing counterfactual cases, and stresses the importance of logical thinking when you read books on business management
