This paper describes a multi-agent model built to simulate the process of technological innovation, based on the widely accepted theory that technological innovation can be seen as an evolutionary process. The actors in the simulation include producers and a large number of consumers. Every producer will produce several types of products at each step. Each product is composed of several design parameters and several performance parameters (fitness components). Kauffman’s famous NK model is used to deal with the mapping from design parameter space (DPS) to performance parameter space (PPS). In addition to the constructional selection, which can be illustrated by the NK model, we added environmental selection into the simulation and explored technological innovation as the result of the interaction between these two kinds of selection.

1 0 0 0 OA 連体修飾節にみられるウ・ウズル

著者: 中沢紀子
出版者: 筑波大学大学院博士課程文芸・言語研究科日本語学研究室

本稿は、中世末期の日本語を反映していると言われるキリシタン資料を用いて、連体節述部のウ・ウズルがどのような条件下で現れやすいのか、その使用実態を調査したものである。調査から、連体節述部のウ・ウズルは「動詞+ウ」「動詞+ウズル」といった述部形式が多く、タリやテアルとウ・ウズルとの共起は殆どみられないことがわかる。また、この連体節の被修飾名詞には、形式名詞の出現傾向が高い。連体節述部と共起する副詞には、時間・時点を表す副詞の用例が多くみられる。これらの副詞が表す連体節の事態についてみると、時間的前後関係は主節の表す事態より後のものである。

The tathāgatadharmakāya (如來法身) called tathāgatagarbha (如來藏) or buddhadhātu (佛性) within all sentient beings is considered to be covered with and corrupted by numerous thousands of millions of afflictions, and therefore cannot demonstrate fully the act of blessing to be granted by the Tathāgata to all sentient beings. Tathāgatagarbha is, however, recognized as nothing other than the perfect Tathāgata himself on the grounds that both tathāgatagarbha and the Tathāgata are essentially dharmakāya and tathatā (眞如). And this understanding of tathāgatagarbha has given rise to two serious problems in this theory: the first is the problem why the eternally pure tathāgatadharmakāya (i.e. the Tathāgata) becomes corrupted by afflictions, and the second is the problem why sentient beings are required to perform religious practice in order to attain supreme enlightenment since all of them have already attained the perfect Tathāgata within themselves. Though some of the scriptures of this theory such as the Śrī-mālādevīsimhanādasūtra (勝鬘經) and the Mahāparinirvānasūtra (・槃經) tried to answer these questions, reasonable resolution has seemed almost impossible since these two problems originate from the fundamental understanding of this theory that by the blessing of the Tathāgata all sentient beings have tathāgatadharmakāya within themselves which ensures them the attainment of supreme enlightenment.There finally appeared one sūtra, the Mahābherīsūtra (大法鼓經, MBhS), that resolved these problems at one stroke. This paper attempts to examine and elucidate precisely the process of resolution of the problems proposed by the MBhS based on the eternity of the Tathāgata. Through this examination the paper also illustrates how one idea of Buddhism develops in the Buddhist history.
