Quantum Systems in Chemistry and Physics: Progress in Methods and Applications is a collection of 33 selected papers from the scientific contributions presented at the 16th International Workshop on Quantum Systems in Chemistry and Physics (QSCP-XVI), held at Ishikawa Prefecture Museum of Art in Kanazawa, Japan, from September 11th to 17th, 2011. The volume discusses the state of the art, new trends, and the future of methods in molecular quantum mechanics and their applications to a wide range of problems in (...) physics, chemistry, and biology. The breadth and depth of the scientific topics discussed during QSCP-XVI appears in the classification of the contributions in six parts: I. Fundamental Theory II. Molecular Processes III. Molecular Structure IV. Molecular Properties V. Condensed Matter VI. Biosystems. Quantum Systems in Chemistry and Physics: Progress in Methods and Applications is written for advanced graduate students as well as for professionals in theoretical chemical physics and physical chemistry. The book covers current scientific topics in molecular, nano, material, and bio sciences and provides insights into methodological developments and applications of quantum theory in physics, chemistry, and biology that have become feasible at end of 2011.

本書は、生活者のハピネス(豊かさや幸せ)の視点から科学技術や社会の変革を考える『因果関係から相関へ、個別技術からシステムへ』と題した『武田シンポジウム2018』の内容をまとめたものです。昨今最も注目を 浴びている科学技術である「AI」、「免疫システム研究」、「民間宇宙ロケット開発」の3つと異なる切り口から、ビッグデータと言われる時代の科学の方法論、個の集積以上の意味をもつシステムとしてのアプローチに ついて立体的に考察します。.

In recent times, international comparative studies on managers’ beliefs regarding ethical/unethical leadership have increased in number. These studies focus on both Eastern and Western countries. However, although these previous studies focused on the effects of national culture, they did not pay sufficient attention to the effects of institutions. Moreover, these studies covered only a few countries. Despite Japan’s strong influence on the world economy, it has not been included in previous studies on ethical leadership. Thus, to reveal unexplored factors—particularly cultural (...) and institutional factors—and to determine the generalizability of previous findings, this study used a qualitative research method to examine Japanese business managers’ beliefs about ethical/unethical leadership. The data revealed the convergence and divergence in beliefs regarding ethical/unethical leadership between managers in Japan and in other countries. The analysis identified mostly the same themes of ethical/unethical leadership as found in other countries albeit with different distributions. In addition, We identified new themes that may be specific to Japan or that were neglected in previous studies. Moreover, this study suggests the necessity of considering each society’s history of business ethics and current ethics-related institutional contexts in ethical/unethical leadership studies.

Fuzzy logic has become an important tool for a number of different applications ranging from the control of engineering systems to artificial intelligence. In this concise introduction, the author presents a succinct guide to the basic ideas of fuzzy logic, fuzzy sets, fuzzy relations, and fuzzy reasoning, and shows how they may be applied. The book culminates in a chapter which describes fuzzy logic control: the design of intelligent control systems using fuzzy if-then rules which make use of human knowledge (...) and experience to behave in a manner similar to a human controller. Throughout, the level of mathematical knowledge required is kept basic and the concepts are illustrated with numerous diagrams to aid in comprehension. As a result, all those curious to know more about fuzzy concepts and their real-world application will find this a good place to start. (shrink)
