In this study, we analyzed the relationship between confirmation bias, which causes people to preferentially view information that supports their opinions and beliefs, and web search behavior. In an online user study, we controlled confirmation bias by presenting prior information to participants that manipulated their impressions of health search topics and analyzed their behavioral logs during web search tasks. We found that web search users with poor health literacy and negative prior beliefs about the health search topic did not spend (...) time examining the list of web search results, and these users demonstrated bias in webpage selection. In contrast, web search users with high health literacy and negative prior beliefs about the search topic spent more time examining the list of web search results. In addition, these users attempted to browse webpages that present different opinions. No significant difference in web search behavior was observed between users with positive prior beliefs about the search topic and those with neutral belief. (shrink)

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.

This paper aims to scrutinize how the notion of risk should be understood and applied to possibly catastrophic cases. I begin with clarifying the standard usage of the notion of risk, particularly emphasizing the conceptual relation between risk and probability. Then, I investigate how to make decisions in the case of seemingly catastrophic disasters by contrasting the precautionary principle with the preventive (prevention) principle. Finally, I examine what kind of causal thinking tends to be actually adopted when we make decisions (...) on emergent cases. My arguments are mainly based on Japan's 2011 massive earthquake and nuclear power station accident. Masaki Ichinose. (shrink)

This paper discusses how to refine a given initial legal ontology using an existing MRD (Machine-Readable Dictionary). There are two hard issues in the refinement process. One is to find out those MRD concepts most related to given legal concepts. The other is to correct bugs in a given legal ontology, using the concepts extracted from an MRD. In order to resolve the issues, we present a method to find out the best MRD correspondences to given legal concepts, using two (...) match algorithms. Moreover, another method called a static analysis is given to refine a given legal ontology, based on the comparison between the initial legal ontology and the best MRD correspondences to given legal concepts. We have implemented a software environment to help a user refine a given legal ontology based on these methods. The empirical results have shown that the environment works well in the field of Contracts for the International Sale of Goods. (shrink)

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.

Since Japan adopted the concept of informed consent from the West, its inappropriate acquisition from patients in the Japanese clinical setting has continued, due in part to cultural aspects. Here, we discuss the current status of and contemporary issues surrounding informed consent in Japan, and how these are influenced by Japanese culture.

篤胤において死の問題は、死後の存在としての霊魂の問題となり、さらには霊魂の行き場所の問題となる。もし人が死後に霊魂となることが確実であり、霊魂の行き着く場所が特定されるのであれば、先に現在の私たちに即 して述べたような死の問題は、「解決」されるに違いない。篤胤はまさにそのことを『霊の真柱』において試み、「幽冥界」という観念を提示することになる。.

Este texto procura traçar algumas linhas gerais da articulação entre música e ironia (ou audição musical e hermenêutica) no romantismo. Procura-se explorar a apropriação original que Søren Kierkegaard fez das “técnicas” hermenêuticas desenvolvidas por Friedrich Schlegel e Friedrich Schleiermacher.

Abstract:Many scientists argue that the world is becoming increasingly dominated by human activity, much to the detriment of the natural world. In what scholars have dubbed the Anthropocene, the current geological epoch during which time human activity has been the dominating force over climate and the environment, many questions of environmental ethics have arisen. Who does the earth belong to? What is the relationship between humans and the environment? What is the moral standing of non-human life? Locke and Rousseau provide (...) varying answers to these questions, which are central to discussions of environmental ethics. In many ways, Locke and Rousseau's answers are opposed to each other, suggesting a differing world view when it comes to environmental ethics. Locke's understanding of environmental ethics seems to dominate, and perhaps even cause, the onset of the Anthropocene, but Rousseau's response, and a potential turn toward his understanding of environmental ethics marks an ideological shift in the way that humans understand their relationship with the world around them. This paper argues that the writings of Locke and Rousseau correspond to different stages of the Anthropocene with significant effects on both environmental ethics and environmental governance and policy.

This paper demonstrates that recent changes in the mass media, especially TV programs, change democratic practice. I argue that this theory is applicable not only to the US, but also to Japan after the 1990s. This paper is organized as follows: the first section confirms that the increase in TV news after the 1980s is driven by an increase in or political news. The second section describes the changes in political practice – elections, policy processes, and party organization brought about (...) by this change in the mass media, using both quantitative and qualitative methods.

Extending techniques of Dowd and those of Poizat, we study computational complexity of in the case when is a generic oracle, where is a positive integer, and denotes the collection of all -query tautologies with respect to an oracle . We introduce the notion of ceiling-generic oracles, as a generalization of Dowd's notion of -generic oracles to arbitrary finitely testable arithmetical predicates. We study how existence of ceiling-generic oracles affects behavior of a generic oracle, by which we show that is (...) not a subset of is comeager in the Cantor space. Moreover, using ceiling-generic oracles, we present an alternative proof of the fact (Dowd) that the class of all -generic oracles has Lebesgue measure zero. (shrink)

日本を代表する「思考の達人」“Meisterdenker”たちは如何にして、明治維新以降、輸入品ではない、日本固有の思考法・方法論を創りだしたのか?続々重版の大好評、入門講義シリーズ。日本に学問として の「哲学」を定着させるうえで決定的な役割を果たした西田幾多郎『善の研究』と日本的な「倫理学」の方法論を開拓したとされる和辻哲郎『人間の学としての倫理学』を熟読し、日本人の深層に在る思想を探る。.

「社会はより良くなる」という「進歩」の理想が失われ、右も左もいまや弱体化している―。200余年にわたるその過程を描き、地球規模の「正義」でなく、自らの現場から始める「ミニマルな正義」を推奨する、この時 代の正義論。.

プラトン以降の西欧哲学・思想史において、“すぐれた哲学・思想”と思われているものが、いかに擬似宗教化の危険性と隣り合わせにありそのことが哲学者・思想家によってどのように問題化され、論じられてきたのか。 本書では、現代思想に特に強い影響を与えたハイデガー、アーレント、デリダなどの論考をてがかりに、思想史の概観を試みる。新興宗教体験を持つ著者だからこそ、現代日本の思想業界に、“生き生きとしたラディカルな 思想”を中心とした「真の共同体」を求めるかのような、擬似宗教化の風潮が生じていることが分かるのである。.

The functions and expression pattern of urea cycle enzymes have undergone considerable changes during the course of evolution. Sequence analyses shows that urea cycle enzymes from mammals are homologous to microbial enzymes of the arginine‐metabolic pathway. Recently, an unexpected relationship was found between argininosuccinate lyase (EC 4.3.2.1), the fourth enzyme of the cycle, and δ‐crystallin, a lens structural protein of birds and reptiles.

This note is a continuation of our former paper ''Complexity of the r-query tautologies in the presence of a generic oracle.'' We give a very short direct proof of the nonexistence of t-generic oracles, a result obtained first by Dowd. We also reconstitute a proof of Dowd's result that the class of all r-generic oracles in his sense has Lebesgue measure one.
