A challenge in human genome research is how to describe the populations being studied. The use of improper and/or imprecise terms has the potential to both generate and reinforce prejudices and to diminish the clinical value of the research. The issue of population descriptors has not attracted enough academic attention outside North America and Europe. In January 2012, we held a two-day workshop, the first of its kind in Japan, to engage in interdisciplinary dialogue between scholars in the humanities, social (...) sciences, medical sciences, and genetics to begin an ongoing discussion of the social and ethical issues associated with population descriptors.

In the name of efficiency, the practice of education has come to be dominated by neoliberal ideology and procedures of standardization and quantification. Such attempts to make all aspects of practice transparent and subject to systematic accounting lack sensitivity to the invisible and the silent, to something in the human condition that cannot readily be expressed in an either-or form. Seeking alternatives to such trends, Saito reads Dewey’s idea of progressive education through the lens of Emersonian moral perfectionism (to (...) borrow a term coined by Stanley Cavell). She elucidates a spiritual and aesthetic dimension to Dewey’s notion of growth, one considerably richer than what Dewey alone presents in his typically scientific terminology. (shrink)

Everyday aesthetic experiences and concerns occupy a large part of our aesthetic life. However, because of their prevalence and mundane nature, we tend not to pay much attention to them, let alone examine their significance. Western aesthetic theories of the past few centuries also neglect everyday aesthetics because of their almost exclusive emphasis on art. In a ground-breaking new study, Yuriko Saito provides a detailed investigation into our everyday aesthetic experiences, and reveals how our everyday aesthetic tastes and judgments (...) can exert a powerful influence on the state of the world and our quality of life. By analysing a wide range of examples from our aesthetic interactions with nature, the environment, everyday objects, and Japanese culture, Saito illustrates the complex nature of seemingly simple and innocuous aesthetic responses. She discusses the inadequacy of art-centered aesthetics, the aesthetic appreciation of the distinctive characters of objects or phenomena, responses to various manifestations of transience, and the aesthetic expression of moral values; and she examines the moral, political, existential, and environmental implications of these and other issues.

One of the ethical principles of medical research involving human subjects is obtaining proper informed consent (IC). However, if the participants’ actual awareness of medical research terminology is lower than the researchers’ prediction of that awareness, it may cause difficulty obtaining proper IC. Therefore, this study aims to clarify the presence of “perception gaps” and then discuss IC-related issues and measures based on the insights obtained. We conducted two online surveys: a “public survey” to understand the Japanese public’s awareness of (...) 11 medical research terms and a “physicians’ survey” to investigate physicians’ predictions regarding public awareness. In the “public survey,” for each term, respondents were instructed to select their situation from “understand,” “have heard,” or “have never heard.” In the “physicians’ survey,” respondents were asked to estimate the proportions of the general public who would “have understood,” “have heard,” or “have never heard” by using an 11-step scale. We analyzed separately in two age groups to understand the age-related difference. We received 1002 valid responses for the “public survey” and 275 for the “physicians’ survey.” Of the public respondents, more than 80% had never heard of terms such as interventional study, prospective clinical study, cohort study, Phase I clinical trial, or double-blind study. Concurrently, physicians overestimated general public awareness of the terms placebo, cohort study, double-blind study, and randomized clinical trial (in the group of people under 60). The results revealed the perception gap between the general public and physicians which raise serious concerns about obtaining proper IC from clinical research participants. (shrink)

To apply reinforcement learning to difficult classes such as real-environment learning, we need to use a method robust to perceptual aliasing problem. The exploitation-oriented methods such as Profit Sharing can deal with the perceptual aliasing problem to a certain extent. However, when the agent needs to select different actions at the same sensory input, the learning efficiency worsens. To overcome the problem, several state partition methods using history information of state-action pairs are proposed. These methods try to convert a POMDP (...) environment into an MDP environment, and thus they are sometimes very useful. However, their computation cost is very high especially in large state spaces. In contrast, memory-less approaches try to escape from the aliased states by outputting actions stochastically. However, these methods output actions stochastically even in unaliased states, and thus the learning efficiency is bad. If we desire to guarantee the rationality in POMDPs, it is efficient to output actions stochastically only in the aliased states and to output one action deterministically in the other unaliased states. Hence, to discriminate between aliased states and unaliased states, the utilization of χ² -goodness-of-fit test is proposed by Miyazaki et al. They point out that, in aliased states, the distributions of the state transitions by random search and a particular policy are different. This difference doesn't occur owing to non-deterministic actions. Hence, if the agent can collect enough samples to implement the test, the agent can distinguish between aliased states and unaliased states well. However, such a test needs a large amount of data, and it's a problem how the agent collects samples without worsening learning efficiency. If the agent uses random search in the course of learning, the learning efficiency worsens especially in unaliased states. Therefore, in this research, we propose a new method called Extended On-line Profit Sharing with Judgement (EOPSwJ) to detect important incomplete perception, which doesn't need large computation cost and numerous samples. We use two criterions for detecting important incomplete perceptions to attain a task. One is the rate of transitions to each state, and the other is the deterministic rate of actions. We confirm the availability of EOPSwJ using two simulations. (shrink)

We propose a novel algorithm to transliterate English to Japanese and its application to a voice controlled browser, which enable ordinary Japanese people to browse English Web site by voice. Speech recognition software designed for native English speakers do not work for most Japanese because Japanese can't pronounce English as native English speakers do. Therefore, we combined Japanese speech recognition software with English-to-Japanese transliteration software. The accuracy of our transliteration algorithm is 80% recall for the top candidate, and 92% recall (...) for the top three candidates. The browser using this transliteration algorithm makes it possible for Japanese to navigate English Web pages almost as accurate as Japanese pages by voice commands. (shrink)

The epistemological chasm between how we (implicitly and subjectively) perceive or imagine the actual world and how we (explicitly and “objectively”) think of its underlying entities has motivated perhaps the most disconcerting impasse in human thought: the explanatory gap between the phenomenal and physical properties of the world. Here, I advocate a combination of philosophical skepticism and simplicity as an informed approach to arbitrate among theories of consciousness. I argue that the explanatory gap is rightly a gap in our understanding, (...) but one that is not surprising; and we being observers biased by our first-person perspective and our existence may both hinder and (the realization we have them) assist our reasoning. Further, I unfold the concept of observer into two distinct notions based on its functional and phenomenal aspects, and exploit this device to elucidate the subject-observer relationship. Then, I proceed to analyze the philosophical zombie dilemma. Lastly, I contend that from a skeptical viewpoint, panpsychism (or neutral monism) is the most parsimonious doctrine accounting for the explanatory gap, and suggest that it would be possible to make headway in the hard problem of consciousness by uncovering non-trivial causal relationships between qualia states and functional states, if routine and controlled manipulation of neural circuits were easily available.

This article examines the underexplored relationship between Amartya Sen’s ‘capability approach’ to human well-being and education. Two roles which education might play in relation to the development of capacities are given particular attention: (i) the enhancement of capacities and opportunities and (ii) the development of judgement in relation to the appropriate exercise of capacities.

Recently, many opportunities have emerged to use the Internet in daily life and classrooms. However, with the growth of the World Wide Web (Web), it is becoming increasingly difficult to find target information on the Internet. In this study, we explore a method for developing the ability of users in information seeking on the Web and construct a search process feedback system supporting reflective activities of information seeking on the Web. Reflection is defined as a cognitive activity for monitoring, evaluating, (...) and modifying one's thinking and process. In the field of learning science, many researchers have investigated reflective activities that facilitate learners' problem solving and deep understanding. The characteristics of this system are: (1) to show learners' search processes on the Web as described, based on a cognitive schema, and (2) to prompt learners to reflect on their search processes. We expect that users of this system can reflect on their search processes by receiving information on their own search processes provided by the system, and that these types of reflective activity helps them to deepen their understanding of information seeking activities. We have conducted an experiment to investigate the effects of our system. The experimental results confirmed that (1) the system actually facilitated the learners' reflective activities by providing process visualization and prompts, and (2) the learners who reflected on their search processes more actively understood their own search processes more deeply.
