This special 10th anniversary edition of the David Suzuki classic, re-examines our place in the natural world in light of sweeping environmental changes and recent advances in scientific knowledge.

「仁」と「天理」はどう語られてきたか―『春秋』三伝・『論語』をはじめとする経典類から二十四史まで、さらに「侯馬盟書」等の出土史料を渉猟して「仁」の原義とその変質、「天理」観との関わりを検討し、その観念 と暦・天文・度量衡・十二方位・楽・易との関係、建築物への數理的表象に説き及ぶ。.

熊本大学生命倫理論集第3巻のテーマは「生命の価値」そのものである。生命倫理が前提とする生命という価値についての根本的問いかけに、哲学、倫理学、法学、医学、脳科学、生物学等の様々な分野の専門家が本気で取 り組み、学問の境界を越えた議論を展開する。.

The objective of this study is to design a laboratory experiment to explore the effect of ambiguity on a subject’s search behavior in a finite-horizon sequential search model. In so doing, we employ a strategy to observe the potential trend of reservation points that is usually unobserved. We observe that subjects behaving consistently across treatments reduce their reservation points in the face of ambiguity over point distribution. Our result is consistent with the theoretical implication obtained by Nishimura and Ozaki.

This paper proposes a class of independence axioms for simple acts. By introducing the E\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {E}}$$\end{document}-cominimum independence axiom that is stronger than the comonotonic independence axiom but weaker than the independence axiom, we provide a new axiomatization theorem of simple acts within the framework of Choquet expected utility. Furthermore, in order to provide the axiomatization of simple acts, we generalize Kajii et al. into an infinite state space. Our axiomatization theorem relates (...) Choquet expected utility to multi-prior expected utility through the core of a capacity that is explicitly derived within our framework. Our result in this paper also derives Gilboa, Eichberger and Kelsey, and Rohde as a corollary. (shrink)

生殖医療・遺伝子改変等の広範な領域におけるキーコンセプトとしての「ヒト胚の道徳的地位」，種々の宣言等で使用されながら意味が曖昧な「人間の尊厳」を多角的に考察する。.

本書ではデータ解析にもとづく倫理学の理論の概要を述べるとともに，総計6,000名にのぼる高校生等への意識調査の結果を踏まえた，自己決定の時代の現状分析を行っている。現状分析の内容は，マスコミによるイメ ージ操作の検証，個人主義的自由主義の原理であるミルの原理の受容状況や問題点，いじめの分析，他者概念の検討，大人と子供の境界の曖昧化現象の考察等であるが，それらを貫く縦糸は「自己決定」，「自由」である。 また現代は，生命や環境，情報といった領域で，社会のレベルでも自己決定する必要に迫られている。本書の提唱するところの調査にもとづく倫理学の方法は，いわゆる「反省的均衡」の方法を実行可能にするものであり， 社会的自己決定を導く有力な方法である。.

Since sending explicit messages can be costly, people often utilize “what is not said,” i.e., informative silence, to economize communication. This paper studies the efficient communication rule, which is fully informative while minimizing the use of explicit messages, in cooperative environments. It is shown that when the notion of context is defined as the finest mutually self-evident event that contains the current state, the efficient use of informative silence exhibits the defining property of indexicals in natural languages. While the efficient (...) use of silence could be complex, it is also found that the efficient use of silence can be as “simple” as the use of indexicals in natural languages if and only if the information structure satisfies some centrality and dominance properties.

This article analyzes investors’ portfolio selection problems in a two-period dynamic model of Knightian uncertainty. We account for the existence of portfolio inertia in this two-period framework. Furthermore, by incorporating investors’ updating behavior, we analyze how observing new information in the first period will affect investors’ behavior. By this analysis, we show that observing new information in the first period will expand portfolio inertia in the second period compared with the case in which observing new information has not been gained (...) in the first period if the degree of Knightian uncertainty is sufficiently large.

本書は、戦国時代の混乱を武力を以て終わらせた徳川家康の統治思想が、日本の公共哲学の原型であるという意表を突く主張から始まる。そして、家康に淵源し、以後250年に及ぶ平和と安定を支えた公共哲学を、鈴木正 三、『葉隠』、白隠慧鶴、太宰春台、海保青陵、そして福澤諭吉の思想に探ってゆくのである。西欧のヒューマニズムが基づく軍事と土地所有ではなく、軍事と商業。すなわち、武士と商人の相互性と、両者のバランス感覚 としてのヒューマニズム、そしてそれが育んだ自生的秩序が日本の公共性の核心にあることを、「慈悲」と「正直」を鍵語に解き明かす。現代の公共哲学に歴史からの再考を迫る、知的冒険の書である。.

A circadian clock, with physiological characteristics similar to those of eukaryotes, functions in the photosynthetic prokaryote, cyanobacteria. The molecular mechanism of this clock has been efficiently dissected using a luciferase reporter gene that reports the status of the clock. A circadian clock gene cluster, kaiABC, has been cloned via rhythm mutants of cyanobacterium, Synechococcus, and many clock mutations mapped to the three kai genes. Although kai genes do not share any homology with clock genes so far identified in eukaryotes, analysis (...) of their expression suggests that a negative feedback control of kaiC expression by KaiC generates the circadian oscillation and that KaiA functions as a positive factor to sustain this oscillation.

Shehtman and Skvortsov introduced Kripke bundles as semantics of non-classical first-order predicate logics. We show the structural equivalence between Kripke bundles for intermediate predicate lógics and Kripke-type frames for intuitionistic modal propositional logics. This equivalence enables us to develop the semantical study of relations between intermediate predicate logics and intuitionistic modal propositional logics. New examples of modal counterparts of intermediate predicate logics are given.

To become more broadly applicable, positions on AI ethics require perspectives from non-Western regions and cultures such as China and Japan. In this paper, we propose that the addition of the concept of harmony to the discussion on ethical AI would be highly beneficial due to its centrality in East Asian cultures and its applicability to the challenge of designing AI for social good. We first present a synopsis of different definitions of harmony in multiple contexts, such as music and (...) society, which reveals that the concept is, at its core, about well-balanced relationships and appropriate actions which give rise to order, balance, and aesthetically pleasing phenomena. The mediator for these well-balanced relationships isTaktwhich is an ability to act thoughtfully and sensibly according to the specific situation and to put things into proportion and order. We propose that the central challenge of building harmonizing AI is to make intelligent systems tactful and also to design and use them tactfully. For an AI system to become tactful, it needs to be able to have an advanced sensitivity to the specific contexts which it is in and their social and ethical implications and have the capability of approximately inferring the emotional and cognitive states of people with whom it is interacting.
