In his 1975 paper “The Meaning of ‘Meaning’”, Hilary Putnam famously argued for semantic externalism. Little attention has been paid, however, to the fact that already in 1973, Putnam had presented the idea of the linguistic division of labor and the Twin Earth thought experiment in his comment on Wilfrid Sellars’s “Meaning as Functional Classification” at a conference, and Sellars had replied to Putnam from a broadly inferentialist perspective. The first half of this paper aims to trace the development of (...) Putnam’s semantic externalism, situate his debate with Sellars in it, and reconstruct the two arguments he presented against Sellars. The second half of this paper aims to reconstruct how Sellars replied to Putnam. I argue that Sellars not only accepts the social character of language but also suggests how inferentialists can accommodate the contribution of the world. Sellars’s key idea is that substance terms have a “promissory note aspect” which is to be cashed out in a successor conceptual framework. I reconstruct Sellars’s position as ideal successor externalism, and compare it with temporal externalism. (shrink)

This article reviews Scott McQuire's book, The Media City, which focuses on the historical formation of the media-architecture complex of the current urban environment. While the book provides rich insights into the ways various media technologies have become interconnected with urban architectural structures, the underlying concept of media in McQuire's discussion could be criticized in three respects: visual-centred, technology-based and real-time oriented. After considering these three points in the context of the theoretical ideas put forward by Henri Lefebvre, Friedrich Kittler (...) and Walter Benjamin, particular attention is paid to Benjamin's prominent figure of the flâneur. Through reconsidering the experience of the flâneur in terms of the technique of getting lost in the city, possibilities are suggested as to thinking differently about the `media city'. In other words, it is proposed that we should examine the theoretical possibilities concerning the modern urban experience between the `media city' and the `city as a medium'. (shrink)

Objective: Population based cohort studies involving genetic research have been initiated in several countries. However, research published to date provides little information on the willingness of the general population to participate in such studies. Furthermore, there is a need to discover the optimal methods for acquiring fully informed consent from the general population. We therefore examined the results of a population based genetic cohort study to identify the factors affecting the participation rate by members of the general public and also (...) specifically to examine the impact of different consent procedures on the rate of participation by prospective candidates and their subsequent withdrawal rate from the study.Design: Descriptive analyses.Setting and participants: The study evaluated two non-genetic subcohorts comprising 3166 people attending for a health checkup during 2002, and two genetic subcohorts comprising 2195 people who underwent a checkup during 2003.Main outcome measurements: Analysis endpoints were differences in participation rates between the non-genetic and genetic subcohorts, differences between providing non-extensive and extensive preliminary information, and changes in participation status between baseline and at 6 months.Results: Participation rates in the genetic subcohorts were 4·7–9·3% lower than those in the non-genetic subcohorts. The odds ratios of participation in genetic research were between 0·60 and 0·77, and the OR for withdrawal from the research was over 7·70; providing preliminary extensive information about genetic research reduced the withdrawal risks but worsened participation rates .Conclusions: The general population responded sceptically towards genetic research. It is crucial that genetic researchers utilise an informative and educational consent process worthy of public trust. (shrink)

The objective of this paper is to study stable coalition structures in symmetric majority games. We assume that players deviate from a coalition structure to another to maximize their power given by the Owen power index. We introduce three myopic core concepts and one farsighted stability concept, the farsighted vNM stable set. Our main result is that the pessimistic core, the largest myopic core, coincides with some farsighted vNM stable set for any number of players. Moreover, we show that a (...) coalition structure belongs to the pessimistic core and the farsighted vNM stable set if and only if it contains an exact majority coalition. (shrink)

In the study of reference assignment, the question of what pragmatic criteria are used to evaluate the resulting interpretation seems not yet to have been properly dealt with. This paper addresses the issue by examining factors which affect the acceptability of various cases of bridging reference. It demonstrates that even highly successful accounts of reference assignment which place major emphasis on accessibility factors, e.g. the accessibility of candidate referents and the accessibility of contextual assumptions, must nonetheless involve some pragmatic criterion (...) with which hearers can evaluate the resulting interpretation. Moreover, it argues that the pragmatic criterion used in reference assignment is not the truth-based one, which has been widely accepted, but the criterion of consistency with the principle of relevance proposed by Sperber and Wilson. Various accounts are tested against a wide range of examples on which I have conducted experimental tests with several sets of subjects. (shrink)

We study stable strategy profiles in a pure exchange game of bads, where each player dumps his or her bads such as garbage onto someone else. Hirai et al. (Mathematical Social Sciences 51(2):162–170, 2006) show that cycle dumping, in which each player follows an ordering and dumps his or her bads onto the next player, is a strong Nash equilibrium and that self-disposal is $$\alpha $$ -stable for some initial distributions of bads. In this paper, we show that a strategy (...) profile of bullying, in which all players dump their bads onto a single player, becomes $$\alpha $$ -stable for every exchange game of bads. We also provide a necessary and sufficient condition for a strategy profile to be $$\alpha $$ -stable in an exchange game of bads. In addition, we show that repeating an exchange after the first exchange makes self-disposal stationary. (shrink)

Anthropomorphic agents used in online-shopping need to be trusted by users so that users feel comfortable buying products. In this paper, we propose a model for designing trustworthy agents by assuming two factors of trust, that is, emotion and knowledgeableness perceived. Our hypothesis is that when a user feels happy and perceives an agent as being highly knowledgeable, a high level of trust results between the user and agent. We conducted four experiments with participants to verify this hypothesis by preparing (...) transition operators utilizing emotional contagion and knowledgeable utterances. As a result, we verified that users' internal states transitioned as expected and that the two factors significantly influenced their trust states. (shrink)

Amid continuing social unrest from the Great East Japan Earthquake and subsequent Fukushima nuclear accident of 2011, the Japanese government announced plans for a major biobanking project in the disaster-stricken areas, to be administered by the ‘Tohoku Medical Megabank Organization’ (ToMMo). This project differs from previous biobanking projects in that it 1) was initiated mainly to boost post-disaster recovery and reconstruction; and 2) targets the area’s survivors as its primary subjects. Here, we review the ethics of the ToMMo biobanking project (...) within the wider context of disaster remediation. (shrink)

The commutativity of the 1-dimensional XY-h type Hamiltonian and the transfer matrix of a 2-dimensional spin-lattice model constructed from an R-matrix is studied by Sutherland's method. We generalize Krinsky's result to more general Hamiltonians and more general R matrices, and we obtain a generic condition on their parameters for the commutativity, which defines an irreducible algebraic manifold in the parameter space.

This study aimed to propose a novel method for designing a product recommendation virtual agent that can keep users motivated to interact with the agent. In prior papers, many methods of keeping users motivated postulated real-time and multi-modal interactions. The proposed novel method can be used in one-direction interaction. We defined the notion of the “hidden vector,” that is, information that is not mentioned by a PRVA and that the user can suppose spontaneously. We conducted an experiment to verify the (...) hypothesis that PRVAs having a hidden vector are more effective than other PRVAs. As a result, it was shown that PRVAs having a hidden vector were perceived as being more persuasive than other PRVAs and strongly motivated the users to use the PRVAs. From these results, the proposed method was shown to be effective. (shrink)

In 2005 Japan completed its first census after the Personal Information Protection Law went into force in April 2005. The debate about the new law raised privacy concerns for the first time among the public. The news-media also provided several examples of possible lack of safeguards in the data collection of sensitive personal information required for the census. The result was the highest non-response rate ever for the Japanese census. Consequently, its accuracy and role as a source for the reliable (...) national statistics for health/welfare policy-making is now critically threatened. In this paper we argue the necessity to adopt specific safeguards to protect personal data in any future census if the trend of increasing non-response rates is to be reversed. We provide some suggestions for such safeguards, and criticize the Japanese government’s response of focusing exclusively on the mechanism of data collection as a means of meeting the privacy challenge.

The purpose of this study was to evaluate the effectiveness of an educational intervention regarding end-of-life discussion directed at older Japanese adults and their attitude to and acceptance of this intervention. A quasi-experimental design was used. A total of 121 older adults, aged 65 years and over, consented to participate. Data from 55 intervention and 57 control participants were used for the analysis. The intervention consisted of an education program comprising a video, a lecture using a handout, and discussion among (...) participants. The control group received only the handout. Both groups were followed up after one month. The intervention group’s attitude became more favorable towards advance directives, especially living wills (P = 0.024). In addition, their expression of preference for life-sustaining treatment by means of artificial nutrition was less at follow up, demonstrating that these older adults had become more autonomous (P = 0.008). There was greater acceptance of the intervention as a whole by the intervention group compared with the control group (P = 0.011). Although few participants overall completed living wills, at follow up twice as many in the intervention group had discussed end-of-life matters with family members and/or their physician. (shrink)

This study investigates simple games. A fundamental research question in this field is to determine necessary and sufficient conditions for a simple game to be a weighted majority game. Taylor and Zwicker showed that a simple game is non-weighted if and only if there exists a trading transform of finite size. They also provided an upper bound on the size of such a trading transform, if it exists. Gvozdeva and Slinko improved that upper bound; their proof employed a property of (...) linear inequalities demonstrated by Muroga. In this study, we provide a new proof of the existence of a trading transform when a given simple game is non-weighted. Our proof employs Farkas’ lemma, and yields an improved upper bound on the size of a trading transform. We also discuss an integer-weight representation of a weighted simple game, improving the bounds obtained by Muroga. We show that our bound on the quota is tight when the number of players is less than or equal to five, based on the computational results obtained by Kurz. Furthermore, we discuss the problem of finding an integer-weight representation under the assumption that we have minimal winning coalitions and maximal losing coalitions. In particular, we show a performance of a rounding method. Finally, we address roughly weighted simple games. Gvozdeva and Slinko showed that a given simple game is not roughly weighted if and only if there exists a potent certificate of non-weightedness. We give an upper bound on the length of a potent certificate of non-weightedness. We also discuss an integer-weight representation of a roughly weighted simple game. (shrink)

The world’s population is currently aging, and the issue of ageism has become serious worldwide, including in Japan. Negative attitudes toward older adults can have undesirable effects on the mental and physical health of this group. We focused on the effects of contact experience with older adults and germ aversion, or the degree of aversion to infection, on negative attitudes toward older adults. Additionally, we included a moderating variable; youth identity, or the sense of belonging with younger rather than older (...) age groups. An online survey was conducted with Japanese participants. We conducted multiple regression analyses and the results showed that the interaction effect between youth identity and contact experience on negative attitudes toward older adults was significant. The findings suggest that contact experience may help in reducing negative attitudes toward older adults among people with low youth identity. The interaction effect between youth identity and germ aversion, however, was not significant. Academic research on the effects of some psychological interventions should pay particular attention to the role of youth identity. Future directions for empirical studies are also discussed.

In Japan, many incidents regarding manga-like virtual agents have happened recently, in which critics have indicated that virtual agents used in public spaces are too sexual. Prior study defined this perception as “moe-phobia.” In many cases, critics have pointed to agents' clothes. However, after verifying actual moe-phobia incidents, I hypothesize that these incidents are associated with not only the agents' clothes but also the situations in which they are used. I conducted an experiment with three factors and two levels to (...) verify this hypothesis. The independent values were the agents' clothes, usage scenario, and the gender of the participants. The dependent values were the agents' trustworthiness, familiarity, likability, sexuality, and suitability as perceived by humans. I conducted the experiment with female and male groups and conducted a three-way ANOVA for each dependent value for each group. As a result, I observed a different tendency regarding the impression of the agents between female and male groups; however, both groups had the same tendency regarding the perceived suitability. The female and male participants judged the agents' suitability from not only their clothes but also the scenario. (shrink)

In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous (...) research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism.

Background: Sharing of tissue samples for research and disease surveillance purposes has become increasingly important. While it is clear that this is an area of intense, international controversy, there is an absence of data about what researchers themselves and those involved in the transfer of samples think about these issues, particularly in developing countries. Methods: A survey was carried out in a number of Asian countries and in Egypt to explore what researchers and others involved in research, storage and transfer (...) of human tissue samples thought about some of the issues related to sharing of such samples. Results: The results demonstrated broad agreement with the positions taken by developing countries in the current debate, favoring quite severe restrictions on the use of samples by developed countries. Conclusions: It is recommended that an international agreement is developed on what conditions should be attached to any sharing of human tissue samples across borders. (shrink)

Philosophers have long debated whether, if determinism is true, we should hold people morally responsible for their actions since in a deterministic universe, people are arguably not the ultimate source of their actions nor could they have done otherwise if initial conditions and the laws of nature are held fixed. To reveal how non-philosophers ordinarily reason about the conditions for free will, we conducted a cross-cultural and cross-linguistic survey (N = 5,268) spanning twenty countries and sixteen languages. Overall, participants tended (...) to ascribe moral responsibility whether the perpetrator lacked sourcehood or alternate possibilities. However, for American, European, and Middle Eastern participants, being the ultimate source of one’s actions promoted perceptions of free will and control as well as ascriptions of blame and punishment. By contrast, being the source of one’s actions was not particularly salient to Asian participants. Finally, across cultures, participants exhibiting greater cognitive reflection were more likely to view free will as incompatible with causal determinism. We discuss these findings in light of documented cultural differences in the tendency toward dispositional versus situational attributions. (shrink)

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen (...) different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

In this article, we present evidence that in four different cultural groups that speak quite different languages there are cases of justified true beliefs that are not judged to be cases of knowledge. We hypothesize that this intuitive judgment, which we call “the Gettier intuition,” may be a reflection of an underlying innate and universal core folk epistemology, and we highlight the philosophical significance of its universality.
