In this paper we are primarily concerned with political expertise, interest, and agreement as factors that might accelerate the flow of information between citizens. We examine dyadic exchanges of information as a function of two primary sets of factors: the characteristics of the citizens in the dyadic relationship and the characteristics of the larger network within which the dyad is located. Moreover, we compare political communication within dyads across several different national contexts: Germany, Japan, and the United States. We assume (...) that citizens are more likely to obtain information from people they trust, but why do they trust some individuals more than others? Is the frequency of communication predicated on shared political preferences? Or is it based on one citizen's assessment regarding the political expertise of another? The answers to these questions have important implications for whether social communication and social capital create added value in the collective deliberations of democratic politics. (shrink)

A new selection of writings on education by Buddhist philosopher and founder of Soka University, Daisaku Ikeda. Culled from some five decades of the author's works, this collection presents educational proposals, lectures to university students, and personal essays. The author delves not only into the meaning of Soka (value-creating) education but offers a hopeful vision of the power of education to bring happiness to the individual and peace to the world.

A New Way Forward is a compilation of seven university lectures that Daisaku Ikeda, the Soka Gakkai International president, gave in the United States, one in 1974 and the others in the 1990s. The earliest from April 1974 when Mr. Ikeda spoke at the invitation of the University of California, Los Angeles, about positive steps that can be taken to begin the twenty-first century in peace and with confidence in the future. Daisaku Ikeda's Buddhist faith and his (...) enduring wish for peace and a better world prevailed as he accepted each invitation to speak. He cherished the chance to share his beliefs and ideas with others. Each time as he finished a lecture, he felt a sense of fulfillment in having been able to convey a portion of his thoughts, and his confidence grew as he pursued each new creative challenge. It is Daisaku Ikeda's hope that the proposals for peace, observations on history, and views of education and arts offered in the pages would have a positive effect on the thinking and life of the reader, in some way or other.

An infinite structure is said to be minimal if each of its definable subset is finite or cofinite. Modifying Hrushovski's method we construct minimal, non strongly minimal structures with arbitrary finite dimensions. This answers negatively to a problem posed by B. I Zilber.

This book examines the broad historical process of introducing engineering ethics in Japan from the late nineteenth century to the twentieth century. The author discusses this process from a comprehensive perspective, including not only engineering education but also various issues in science, technology, and society studies.

Children will appreciate the conversational tone of this collection of personal essays written just for them by one of world's great philosophers, Daisaku Ikeda. "Let's begin our talk," he writes, "as if we were strolling together under clear blue skies." The author's love, respect and high hopes for boys and girls fill every page. At every turn, children will be inspired to think about life and their role in the world in ways, perhaps, they've never thought of before. As (...) a man of peace himself, Mr. Ikeda sees children as the successors in bringing justice, kindness, and happiness to people everywhere. And he challenges children to take always try hard and develop themselves--each in their own unique way--so that they can live lives of true fulfillment. Drawing on episodes from the author's life, from great literature, and from Buddhist stories, these essays touch on a variety of topics, such as appreciation, the arts, adventure, courage, history, responsibility. No matter the topic, the overall message comes through: your life is precious, never lose hope, accomplish great things. (shrink)

Genetic Algorithms(GAs) are effective approximation algorithms which focus on “hopeful area” in the searching process. However, in harder problems, it is often very difficult to maintain a favorable trade-off between exploitation and exploration. All individuals leave the big-valley including the global optimum, and concentrate on another big-valley including a local optimum often. In this paper, we define such a situation on conventional GAs as the “UV-phenomenon”, and suggest UV-structures as hard landscape structures that will cause the UV-phenomenon. We introduce a (...) test function which has explicit UV-structures, and show UV-phenomenon caused by them. Next we analyze Fletcher and Powell function to confirm our hypothesis. Finally we propose a novel framework of GAs which can cope with UV-structures. (shrink)

This proposal introduces a novel decision-making framework to advance safe economic activities in cyberspace. We focus on identifying anomalies within crypto-asset trading, recognized as potential sources of criminal activity, severely undermining the credibility of such assets. Detecting and mitigating such anomalies holds significant societal implications, particularly in fostering trust within blockchain networks. We aim to bolster the “social trust” inherent to blockchain technology by facilitating informed economic activities in cyberspace. To achieve this, we propose integrating two artificial intelligence (AI) systems (...) into a blockchain-based decentralized autonomous organization (DAO). The first AI application involves amalgamating various anomaly indicators, spanning from cluster coefficient, entropy, triangular motif analysis, correlation tensor analysis, loop component by Hodge decomposition, loop causality detection, network classification using graph Laplacian, and persistent homology analysis, into a comprehensive indicator using a Boltzmann machine. The second AI application entails deploying conversational AI to guide and support traders, aiding them in making informed trading decisions. This system is designed to alert DAO members to anomalies based on the integrated indicators, especially during massive price fluctuations. We operate under the assumption of close collaboration between governments, experts, traders, system developers, and operators to effectively organize DAOs. The primary technical challenge in our proposal lies in developing a wallet assisted by an intelligent software agent capable of safe interactions with traders within a unified DAO. With this organization, we envision fostering a global economic ecosystem where physical and cyber worlds converge, allowing democratic economic participation. (shrink)

Job-shop Scheduling Problem (JSP) is one of the most difficult benchmark problems. GA approaches often fail searching the global optimum because of the deception UV-structure of JSPs. In this paper, we introduce a novel framework model of GA, Innately Split Model (ISM) which prevents UV-phenomenon, and discuss on its power particularly. Next we analyze the structure of JSPs with the help of the UV-structure hypothesys, and finally we show ISM's excellent performance on JSP.

Recently, agent technologies have attracted a lot of interest as an emerging programming paradigm. With such agent technologies, services are provided through collaboration among agents. At the same time, the spread of mobile technologies and communication infrastructures has made it possible to access the network anytime and from anywhere. Using agents and mobile technologies to realize ubiquitous computing systems, we propose a new framework based on KODAMA and VPC. KODAMA provides distributed management mechanisms by using the concept of community and (...) communication infrastructure to deliver messages among agents without agents being aware of the physical network. VPC provides a method of defining peer-to-peer services based on agent communication with policy packages. By merging the characteristics of both KODAMA and VPC functions, we propose a new framework for ubiquitous computing environments. It provides distributed management functions according to the concept of agent communities, agent communications which are abstracted from the physical environment, and agent collaboration with policy packages. Using our new framework, we conducted a large-scale experiment in shopping malls in Nagoya, which sent advertisement e-mails to users' cellular phones according to user location and attributes. The empirical results showed that our new framework worked effectively for sales in shopping malls. (shrink)

In this paper, we investigate definable models of Peano Arithmetic PA in a model of PA. For any definable model N without parameters in a model M, we show that N is isomorphic to M if M is elementary extension of the standard model and N is elementarily equivalent to M. On the other hand, we show that there is a model M and a definable model N with parameters in M such that N is elementarily equivalent to M but (...) N is not isomorphic to M. We also show that there is a model M and a definable model N with parameters in M such that N is elementarily equivalent to M, and N is isomorphic to M, but N is not definably isomorphic to M. And also, we give a generalization of Tennenbaum's theorem. At the end, we give a new method to construct a definable model by a refinement of Kotlarski's method. (shrink)

We research the political impact of how users access the Internet. Recent research suggests that Internet usage may promote political participation. Internet usage is proposed to be beneficial because it increases activity in diverse politicized social networks and through greater access to information. Even though Internet usage may begin as a non-political activity, we outline several reasons to believe that it may spark later political participation. This impact, however, is likely to be non-existent in new forms of Internet browsing such (...) as through mobile phones, where users do less full-scale browsing. The more difficult browsing interface of mobile phones reduces activity in chat rooms and in-depth browsing of online sources of information which promote participation. To test these ideas, we use nationally representative survey data from Japan, a country which has more pronounced usage of mobile phone browsing. Using a Seemingly Unrelated Regression Model, we also show that the chief determinants of using PC's over mobile phones for Internet browsing are age and education. We then show that PC-based Internet activity correlates with increased political participation, but mobile phone usage correlates with less participation. (shrink)

Hrushovski constructed an -categorical stable pseudoplane which refuted Lachlan's conjecture. In this note, we show that an -categorical projective plane cannot be constructed by "the Hrushovski method.".
