This paper reports on a quiz robot experiment in which we explore similarities and differences in human participant speech, gaze, and bodily conduct in responding to a robot’s speech, gaze, and bodily conduct across two languages. Our experiment involved three-person groups of Japanese and English-speaking participants who stood facing the robot and a projection screen that displayed pictures related to the robot’s questions. The robot was programmed so that its speech was coordinated with its gaze, body position, and gestures in (...) relation to transition relevance places, key words, and deictic words and expressions in both languages. Contrary to findings on human interaction, we found that the frequency of English speakers’ head nodding was higher than that of Japanese speakers in human-robot interaction. Our findings suggest that the coordination of the robot’s verbal and non-verbal actions surrounding TRPs, key words, and deictic words and expressions is important for facilitating HRI irrespective of participants’ native language. Keywords: coordination of verbal and non-verbal actions; robot gaze comparison between English and Japanese; human-robot interaction ; transition relevance place ; conversation analysis. (shrink)

In this paper, we generalize a result of Brown and Simpson [1] to prove that RCA0+Π0∞-BCT is conservative over RCA0 with respect to the set of formulae in the form ∃!Xφ, where φ is arithmetical. We also consider the conservation of Π00∞-BCT over Σb1-NIA+∇b1-CA.

Many educators today think that the school's lessons and activities do not stimulate or engage students' imaginations. In order to alleviate this problem, they tend to use images in conjunction with, or sometimes rather than, words; they employ so-called imaginative or creative activities rather than chalk and talk. However, these principles and methods are based on somewhat misguided or trivial understanding of the importance of imagination in students' lives. Dewey's understanding of the relevance of imagination gives us a useful perspective (...) to better understand where imaginative engagement becomes crucial in education. (shrink)

Study of Vaiśeṣika philosophy with special reference to Vaiśeṣikadaśapadārthaśāstra.

The question of the existence of cultural universals immediately leads us to the problem of intercultural communication and of so-called incommensurability. Over the last few decades, these topics have been the subject of controversy in the philosophy of science, and the stock of universalism has been falling as a result of the rise of Kuhn’s paradigm theory and Quine’s thesis of the indeterminacy of translation. Nowadays cultural pluralism or relativism is rather dominant among philosophers and has begun to appear plausible, (...) too, from an anthropological or sociological point of view. But philosophically, as is well known, relativism harbors many difficulties and paradoxes. As philosophers, therefore, we cannot accept imprudent relativism just as it is. (shrink)

The severe accident at the Fukushima-Daiichi nuclear power plant caused by the March 11 Great East Japan Earthquake in 2011 was a typical disaster in the age of “trans-science,” which means the situation that science and politics are closely connected and inseparable. The stage of trans-science requires a philosophy of trans-science instead of a philosophy of science such as logical positivism. I would like to characterize norms for techno-scientists in the risk society as RISK, which includes Regulatory deliberation, Intergenerational ethics, (...) Social accountability and Knowledge-product liability. (shrink)

It has been suggested that preparing to teach and teaching are conditionally effective in enhancing one’s own learning. This paper focuses on interactivity—the level of teacher-student interaction in expected or actual teaching—as the potential key to understanding and controlling the variability in the effectiveness of learning by preparing to teach and teaching. By summarizing and reanalyzing the results of previous studies, I suggest that the learning benefits of studying with the expectation of direct teaching (i.e., teaching a student face-to-face) are (...) greater than those of studying with the expectation of indirect teaching (i.e., teaching a student indirectly by creating a lecture video, providing written explanations, or using other means) and that learning by direct teaching surpasses learning by explaining to oneself or indirect teaching at least after preparing to do so. Next, three candidate explanations for the impact of interactivity are discussed: the advantages of asking and answering questions, obtaining additional information about and from one’s student, and enhancing one’s motivation to process learning material deeply while preparing to teach and teaching. Finally, I conclude with the remaining questions and directions for future research. (shrink)

In the October edition of the Journal of Medical Ethics, Akabayashi and colleagues state that ’to establish a heterogeneous [induced pluripotent stem cell] iPSC bank covering roughly 80% of Japan’s population…the Japanese government decided to invest JPY110 billion over 10 years in regenerative medicine research; a quarter of this was to be allocated to the iPSC stock project'. While they claim this amount of money to be an unfair distribution of state resources, we believe their assessment is based on a (...) misunderstanding of the facts. Similarly, other criticisms by them are based on mistaken interpretations. This article is a rebuttal to the arguments that form the basis of Akabayashi and colleagues’ five criticisms by explaining their misinterpretations. (shrink)

In this paper, we investigate the logical strength of completeness theorems for intuitionistic logic along the program of reverse mathematics. Among others we show that is equivalent over to the strong completeness theorem for intuitionistic logic: any countable theory of intuitionistic predicate logic can be characterized by a single Kripke model.

Using anthropological theory, this paper examines human–android interactions (HAI) as an emerging aspect of android science. These interactions are described in terms of adaptive learning (which is largely subconscious). This article is based on the observations reported and supplementary data from two studies that took place in Japan with a teleoperated android robot called Telenoid in the socialization of school children and older adults. We argue that interacting with androids brings about a special context, an interval, and a space/time for (...) reflection and imagination that was not there before. During the interaction something happens. There is adaptive learning and as a result, both children and older adults accepted Telenoid, and the children and older adults accepted each other. Using frames of play and ritual, we make sense and ‘capture’ moments of adaptive learning, and the feedback that elicits a social response from all study participants that results in self-efficacy and socialization. While “ritual” refers to the application of what has been learned and “play” means that there are no obvious consequences of what has been learned. This analysis illuminates new understanding about the uncanny valley, cultural robotics and the therapeutic potential of HAI. This has implications for the acceptance of androids in ‘socialized roles’ and gives us insight into the subconscious adaptive learning processes that must take place within humans to accept androids into our society. This approach aims to provides a clearer conceptual basis and vocabulary for further research of android and humanoid development. (shrink)

In this paper, we discuss uniform versions of some axioms of second order arithmetic in the context of higher order arithmetic. We prove that uniform versions of weak weak König's lemma WWKL and Σ01 separation are equivalent to over a suitable base theory of higher order arithmetic, where is the assertion that there exists Φ2 such that Φf1 = 0 if and only if ∃x0 for all f. We also prove that uniform versions of some well-known theorems are equivalent to (...) or the axiom of the existence of the Suslin operator. (shrink)

To explain why students learn effectively by teaching, explaining to others in particular, Koh and colleagues advanced the retrieval practice hypothesis, which attributes the learning benefits entirely to the effect of practicing retrieval, that is, effortfully recalling to-be-taught information for the provision of instructional explanations. After delineating the rationale behind the retrieval practice hypothesis, the current situation of research, and the limitations of the existing approach, this paper proposes three tests for the evaluation of the hypothesis that address whether explaining (...) to others after initial studying surpasses restudying in learning performance, whether the amount of effort to retrieve to-be-taught information from memory moderates the learning effects of explaining to others, and whether the degree of elaboration during retrieval practice positively predicts the outcomes of learning by merely recalling to-be-taught information. Evidence is examined regarding whether each test is passed, and future directions for research on the retrieval practice hypothesis are discussed. (shrink)

Experimental studies have developed, conducted, and evaluated classroom interventions for foreign language anxiety reduction. However, various characteristics of those classroom interventions make it difficult to synthesize the findings and apply them to practice. We conducted what is, to the best of our knowledge, the first systematic review on educational interventions for FLA. Six criteria were established for inclusion of studies. Using English keywords, we identified 854 potentially eligible studies through ProQuest and Scopus, 40 of which were finally included. All included (...) studies were published from 2007 to 2020. The studies differed in type of intervention, duration of intervention, and scale to measure FLA. Our systematic review resulted in seven features of classroom interventions, categorized as student–student interactions, student-teacher interactions, self-management, and mood boosters; we also categorized interventions as either individual or interactional.

The March 11, 2011, Great East Japan Earthquake caused extensive damage to the Tōhoku district of Japan and gave rise to many arguments concerning the meaning of “disaster” as well as the road to recovery. In particular, the severe accident of the Fukushima-Daiichi nuclear power plant reminded us of the overconfidence of science and technology. In this article, I will discuss concepts such as “disaster of civilization,” “impermanence,” “betweenness,” and the double structure of the Japanese view of nature.
