We examine the range of anonymity that is compatible with a Paretian social welfare relation (SWR) on infinite utility streams. Three alternative coherence properties of an SWR are considered, namely, acyclicity, quasi-transitivity, and Suzumura consistency. For each case, we show that a necessary and sufficient condition for a set of permutations to be the set of permissible permutations of some Paretian SWR is given by the cyclicity of permutations and a weakening of group structure. Further, for each case of coherence (...) property, we show that the extended Pareto rule is the least element of the class of anonymous Paretian SWRs. (shrink)

日本人はグローバル化の潮流といかに向き合うべきなのか―そのヒントは「国学」にあった。先人たちが葛藤した問いのなかを私たちはいまも生きている。.

Le présent article a pour but de proposer une méthode de constitution de corpus pour transcrire les traits tant prosodiques que gestuels, qui avaient été peu pris en compte jusqu’à présent. Comme constitutifs du corpus, les aspects formels et kinésiques de l’activité gestuelle, ainsi que le rapport temporel et fonctionnel entre geste et discours sont expliqués, afin de mieux appréhender l’organisation du discours et de l’interaction. A titre d’exemple, une thématisation est analysée.

Discovery of representative Web pages regarding specific topics is important for assisting users' information retrieval from the Web. Researches on Web structure mining, whose goals are to discover or to rank important Web pages based on the graph structure of hyperlinks, have been very active recently. A complete bipartite of Web graph, which is composed of centers (containing useful information regarding specific topic) and fans (containing hyperlinks to centers), can be regarded as a Web community sharing a common interest. Although (...) Murata's method for discovering Web communities is a simple method for finding related Web pages, it has the following weaknesses: (1) since the number of centers increases monotonously, pages irrelevant to the members of Web communities may be added in the process of discovery, and (2) since the number of fans decreases monotonously according as the number of centers increases, the method may suffer topic drift. This paper describes an improved method for refining Web communities in order to acquire representative Web pages of the topics of input Web communities. The method is based on the assumption that most of the fans contain hyperlinks pointing to representative pages regarding their topic, and that hyperlinks to the pages of the same quality often co-occur. In our new method, both fans and centers are renewed iteratively by the result of the majority vote of the members of previous Web community. Results of our experiments show that the new method has abilities of finding desirable pages for several topics. (shrink)

This paper proposes a method for discovering Web communities. A complete bipartite graph K i, j of Web pages can be regarded as a community sharing a common interest. Discovery of such community is expected to assist users’ information retrieval from the Web. The method proposed in this paper is based on the assumption that hyperlinks to related Web pages often co-occur. Relations of Web pages are detected by the co-occurrence of hyperlinks on the pages which are acquired from a (...) search engine by backlink search. In order to find a new member of a Web community, all the hyperlinks contained in the acquired pages are extracted. A page which is pointed by the most frequent hyperlinks is regarded as a new member of the community. We have build a system which discovers complete bipartite graphs based on the method. Only from a few URLs of initial community members, the system succeeds in discovering several genres of Web communities without analyzing the contents of Web pages. (shrink)

This article examines the concept of void with the question of whether the concept forms a sign. A void in this article is defined as a spatio-temporal empty space existing in a representation. The aim of the analysis is to consider the hidden nature of signs, which cannot be highlighted only through an analysis of typical signs within social convention. As a semiotic tool to conduct the discussion, the notion of a zero sign of Lévi-Strauss is introduced. The article considers (...) all possible zeros that can exist within the Saussurian sign model and introduces three cases: an omitted sign, an ambiguous signified, and an ambiguous sign. After examining the features of each kind, the concept of void is considered in these terms, with the conclusion that it belongs to the ambiguous sign case. Analysis of void with respect to the zero sign highlights the nature of signs as being reflexive, holistic and speculative. Because the signifier is barely delimited, it influences the surrounding sign systems, including the one existing at the meta-level. An ambiguous sign is deemed to allow for concept sharing among people even when the signifier and the signified remain ambiguous. (shrink)

This article argues how one problem of computing lies in realizing a significant instance given a class or type. Analysis of a case study on digital narrative suggests two general processes for instantiating significant instances: interaction and optimization. The article then explains how the problem of universals needs to be deconstructed when trying to understand what type of entities significant instances are and what the process for obtaining them is.

Previous findings in cultural psychology indicated that East Asians are more likely than North Americans to be attentive to contextual information (e.g., Nisbett & Masuda, ). However, to what extent and in which conditions culture influences patterns of attention has not been fully examined. As a result, universal patterns of attention may be obscured, and culturally unique patterns may be wrongly assumed to be constant across situations. By carrying out two cross-cultural studies, we demonstrated that (a) both European Canadians and (...) Japanese attended to moving objects similarly when the task was to simply observe the visual information; however, (b) there were cultural variations in patterns of attention when participants actively engaged in the task by constructing narratives of their observation (narrative construction). These findings suggest that cultural effects are most pronounced in narrative construction conditions, where the need to act in accordance with a culturally shared meaning system is elicited.

I explore options for a plenitudinarian solution to the Paradox of Flexible Origin Essentialism, taking as my unlikely starting point the views of Sarah-Jane Leslie, who holds that if plenitudinarianism is true, then there is in fact no paradox to be solved, only the illusion of one. The first three sections are expository: Sect. 1 on plenitudinarianism, Sect. 2 on the paradox, and Sect. 3 on Leslie’s views about how plenitudinarianism bears on the paradox. In Sect. 4, I reject the (...) contention that there is no paradox and critically explore three options for a plenitudinarian solution. In Sect. 5, I argue that the plenitudinarian ought to endorse a fourth option. In Sect. 6, I consider an objection. I endorse neither plenitudinarianism nor its denial; the main aim of the paper is to argue that for one who does endorse plenitudinarianism, the best solution to the Paradox of Flexible Origin Essentialism is clear.

Individual differences in moral views are often explained as the downstream effect of ideological commitments, such as political orientation and religiosity. Recent studies in the U.S. suggest that moral views about recreational drug use are also influenced by attitudes toward sex and that this relationship cannot be explained by ideological commitments. In this study, we investigate student samples from Belgium, The Netherlands, and Japan. We find that, in all samples, sexual attitudes are strongly related to views about recreational drug use, (...) even after controlling for various ideological variables. We discuss our results in light of reproductive strategies as determinants of moral views. (shrink)

Let H be a proof system for quantified propositional calculus (QPC). We define the Σqj-witnessing problem for H to be: given a prenex Σqj-formula A, an H-proof of A, and a truth assignment to the free variables in A, find a witness for the outermost existential quantifiers in A. We point out that the Σq1-witnessing problems for the systems G*1and G1 are complete for polynomial time and PLS (polynomial local search), respectively. We introduce and study the systems G*0 and G0, (...) in which cuts are restricted to quantifier-free formulas, and prove that the Σqj-witnessing problem for each is complete for NC1. Our proof involves proving a polynomial time version of Gentzen’s midsequent theorem for G*0 and proving that G0-proofs are TC0-recognizable. We also introduce QPC systems for TC0 and prove witnessing theorems for them. We introduce a finitely axiomatizable second-order system VNC1 of bounded arithmetic which we prove isomorphic to Arai’s first order theory AID + Σb0-CA for uniform NC1. We describe simple translations of VNC1 proofs of all bounded theorems to polynomial size families of G*0 proofs. From this and the above theorem we get alternative proofs of the NC1 witnessing theorems for VNC1 and AID. (shrink)

明治維新を支えた志士たちは、儒教を行動の指針としていた。尊王攘夷という中国からの思想は、やがて日本中心主義へと置き変わる。.

Adopting a modified Stroop task, the authors tested the hypothesis that processing systems brought to bear on comprehension of emotional speech are attuned primarily to word evaluation in a low-context culture and language (i.e., in English), but they are attuned primarily to vocal emotion in a high-context culture and language (i.e., in Japanese). Native Japanese (Studies 1 and 2) and English speakers (Study 3) made a judgement of either vocal emotion or word evaluation of an emotionally spoken evaluative word. Word (...) evaluations and vocal emotions were comparable in extremity in the two languages. In support of the hypothesis, an interference effect by competing word evaluation in the vocal emotion judgement was significantly stronger in English than in Japanese. In contrast, an interference effect by competing vocal emotion in the word evaluation judgement was stronger in Japanese than in English. Implications for the cultural grounding of communication, emotion, and cognition are discussed. (shrink)

Long-range correlation, a property of time series exhibiting long-term memory, is mainly studied in the statistical physics domain and has been reported to exist in natural language. Using a state-of-the-art method for such analysis, long-range correlation is first shown to occur in long CHILDES data sets. To understand why, Bayesian generative models of language, originally proposed in the cognitive scientific domain, are investigated. Among representative models, the Simon model was found to exhibit surprisingly good long-range correlation, but {\em not} the (...) Pitman-Yor model. Since the Simon model is known not to correctly reflect the vocabulary growth of natural language, a simple new model is devised as a conjunct of the Simon and Pitman-Yor models, such that long-range correlation holds with a correct vocabulary growth rate. The investigation overall suggests that uniform sampling is one cause of long-range correlation and could thus have a relation with actual linguistic processes. (shrink)
