Can individuals express their opinions on youth suffrage without hesitation when asked directly? This study investigates sensitivity bias in attitudes toward youth suffrage and explores the determinants of this bias through two experimental studies in Japan. The results of Study 1 (N = 4,501) conducted in 2020 found that the rate of disagreement with the suffrage for 18-year-olds is underestimated, and young voters are likely to hesitate to express their true opinions when asked directly. This tendency among young Japanese voters (...) was confirmed in the pre-registered Study 2 (N = 1,500) conducted in 2024. The results of exploratory analyses in Study 2 indicated that low internal efficacy may cause this sensitivity bias, while our hypothesis that low self-esteem among young voters generates this tendency was not supported. This study contributes to the understanding of sensitivity bias in public opinion research, particularly in the context of youth suffrage. (shrink)

Lottocracy and epistocracy have received deeply insightful attention as political regimes. Herein, by conducting an experiment using an online survey, we explored the extent to which public opinion is receptive to political decisions under various regimes regarding two environmental policies: education policy and environmental tax policy. By doing so, we examined whether the presence of tax burdens affected the acceptability of political regimes, i.e., electoral democracy, lottocracy, and epistocracy. Our results revealed that decisions based on lottocracy and epistocracy were significantly (...) less acceptable than those based on electoral democracy. Nevertheless, lottocratic and epistocratic decisions were more acceptable regarding the issue of environmental tax policy. The difference was mainly attributed to people's rejection of environmental tax policy offsetting their rejection of lottocracy and epistocracy. This suggests, first, that decisions based on electoral democracy increase policies' acceptability if they do not involve taxation, and second, that the status of whether or not a decision is electoral does not significantly affect policy acceptability if taxation is involved, whereas on the other hand, people are sensitive to differences between the regimes if the policy does not involve taxation.

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.

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 aims at bringing a new philosophical perspective to the current debate on the death penalty through a discussion of peculiar kinds of uncertainties that surround the death penalty. I focus on laying out the philosophical argument, with the aim of stimulating and restructuring the death penalty debate. I will begin by describing views about punishment that argue in favour of either retaining the death penalty (‘retentionism’) or abolishing it (‘abolitionism’). I will then argue that we should not ignore (...) the so-called “whom-question”, i.e. “To whom should we justify the system of punishment?” I identify three distinct chronological stages to address this problem, namely, “the Harm Stage”, “the Blame Stage”, and “the Danger Stage”. I will also identify four problems arising from specific kinds of uncertainties present in current death penalty debates: (1) uncertainty in harm, (2) uncertainty in blame, (3) uncertainty in rights, and (4) uncertainty in causal consequences. In the course of examining these four problems, I will propose an ‘impossibilist’ position towards the death penalty, according to which the notion of the death penalty is inherently contradictory. Finally, I will suggest that it may be possible to apply this philosophical perspective to the justice system more broadly, in particular to the maximalist approach to restorative justice. (shrink)

This paper engages with a specific problem concerning the relationship between descriptive and normative claims. Namely, if we understand that descriptive claims frequently contain normative assertions, and vice versa, how then do we interpret the traditionally rigid distinction that is made between the two, as ’Hume’s law’ or Moore’s ’naturalistic fallacy’ argument offered. In particular, Kripke’s interpretation of Wittgenstein’s ’rule-following paradox’ is specially focused upon in order to re-consider the rigid distinction. As such, the paper argues that if descriptive and (...) normative claims are not mutually exclusive, then we need a new framework with which to understand this relationship. In this regard, the paper borrows from concerns with vagueness, particularly using a degree-theoretic approach in terms of subjective probability, in an attempt to graphically figure out these differences. Consequently, the paper tentatively proposes the hyperbola model in which degrees of normativity and degrees of descriptivity could be expressed and measured. It is hoped, as a result, that this tentative proposal will contribute to deepening the debate on vagueness in general. (shrink)

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.

In this paper, I discuss from a philosophical viewpoint the so-called radiation problem that resulted from the Fukushima Daiichi Nuclear Power Station accident after the Great East Japan Earthquake in 2011. The starting point lies in the conceptual distinction between “damage due to radiation” and “damage caused by avoiding radiation.” We can recognize the direct “damage due to radiation” in Fukushima as not serious based on the empirical data so that I focus upon the problem of the “damage caused by (...) avoiding radiation,” particularly the damage due to evacuation actions. Actually, evacuation actions caused more refugees to die of suicide and diseases than supposed. Obviously, there is a practical problem on whether the forceful and emergent evacuationwas needed. In addition, I will point out that some people psychologically had negative feelings about the radiation problem altogether, for example, absurdity, discomfort, anxiety, or distrust, where some of them tend to twistedly solve those by giving moral censure to people and the product in affected areas. This brought about serious harm to people in Fukushima. I will interpret some people’s careless adoption of precautionary principle and their misunderstanding of the legal standard in radiation protection as being latent in this tragedy. (shrink)

According to the apophthegm reported by Plutarch and Stobaeus (SSR V B 61), Diogenes the Cynic accused Plato of ‘causing pain to no one’ during his long philosophical career. This article considers whether this critique of Plato is accurate by examining previous interpretations and proposing others. First, Plutarch understood the ‘pain’ required by Diogenes as a psychological motivator that drives the young to study hard. This interpretation, however, is implausible because Plato does not seem unfamiliar with this treatment of ‘pain’. (...) Second, Stobaeus connected pain with parrhēsia, likely supposing that a philosopher should tell the truth even if it hurts his audience. Nevertheless, his account needs further clarification since Plato also emphasises the importance of parrhēsia. To resolve the problem, this article proposes a distinction between two kinds of parrhēsia: ‘telling the truth’ and ‘openly making abusive remarks’. Unlike Plato, the Cynics occasionally resort to the latter, which causes sufferers completely passive pain. This kind of pain is certainly alien to Plato’s philosophy, which presupposes some active participation by sufferers. Finally, the article introduces the Cynic concept of askēsis to illuminate another aspect of ‘philosophical pain’. While Plato confines his askēsis to mental labour or moderate physical exercise, the Cynics also demand that individuals undergo physical pain in the course of askēsis. In conclusion, the article argues that Diogenes’ objection to Plato is apt, at least in light of two antithetical natures of ‘pain’: passive/active and physical/mental. (shrink)

This paper tries to develop an epistemological analysis on the notion of responsibility. After pointing out a peculiar kind of uncertainties concerning the notion of responsibility, I focus upon the issue of criminal responsibility, taking the case of mentally disordered offenders into account, and propose the distinction of the phases between sentence and practice with applying Slobogin's idea of integrationism. Finally, I propose a probabilistic approach to the problem of responsibility through considering the idea of relevance ratio, leading to my (...) final proposal concerning the concept of the degrees of responsibility.

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.

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)

In recent years, a number of news stories were reported worldwide involving brain-dead pregnant women. Debates over providing life support to braindead pregnant women and delivery of their children have been around for some decades. Maintaining a woman’s life solely for fetal viability has become a major controversial social issue. Opposing opinions exist where one side supports the woman and her child should be left to die in dignity and the other side claims to protect the unborn child’s right to (...) live. Each group has strong beliefs. This paper addresses main aspects when considering the continuation of somatic support to the brain-dead pregnant woman for the purpose of fetus delivery including; human death, dignity of the woman, rights of the fetus, proportionality of acts, and the woman’s donor status, and independence of mother and fetus. Then, the authors present several diverse opinions and positions concerning the legitimacy of life support for brain-dead women based on them and critically evaluate them. We show that each and every claim can be ethically refuted. This paper also approaches to those claims from three different points of views, which are that of the brain-dead woman, her fetus and her family. We believe that the brain-dead woman’s wish and dignity, the child’s predicted wellbeing after birth, and the family’s beliefs and welfare should all be counted equally when making the final decision. In conclusion, we argue that the decision can be ethically justified only when the interests of all parties are appropriately taken into consideration and protected. (shrink)

Fundamental notions Husserl introduced in Ideen I, such as epochè, reality, and empty X as substrate, might be useful for elucidating how mathematical physics concepts are produced. However, this is obscured in the context of Husserl’s phenomenology itself. For this possibility, the author modifies Husserl’s fundamental notions introduced for pure phenomenology, which found all sciences on the absolute Ego. Subsequently, the author displaces Husserl's phenomenological notions toward the notions operating inside scientific activities themselves and shows this using a case study (...) of the construction of noncommutative geometry. The perspective in Ideen I about geometry and mathematical physics includes points that are inappropriate to modern geometry and to modern physics, especially to noncommutative geometry and to quantum physics. The first point relates to the intuitive character of geometrical objects in Husserl. The second is linked to the notion of locality related to the notion of extension, by which Husserl characterizes the essence of physical things. The points show that the notion of empty X as a substrate, developed in “Phenomenology of Reason” in Ideen I, is helpful for considering the notions of physical reality and of geometrical space, especially reality in quantum physics and space in noncommutative geometry. The salient conclusions include the proposition that aphilosophical study of the relationship between the physical object X, which imparts a unity to what is given to sensibility, and the geometrical space X, which imparts a unity of sense to various mathematical operations, opens a reinterpretation of Husserl’s interpretation, supporting an epistemology of mathematical physics.

I aim to bring the idea of “degree of free will or freedom” into philosophical debates on free will by rejecting the formulation, ‘we are either free or not’. This idea is based upon my viewpoint of regarding freedom as a realistic phenomena actually occurring. First of all, I focus on the fact that it is vague whether an agent is free or not. This vagueness is interpreted as ontic vagueness, corresponding with the status of freedom as real. However, Evans’s (...) argument regarding ontic vagueness must be considered as, according to his argument, ontic vagueness about identity and objects are impossible. I indicate that this argument assumes the truth-value gap position in borderline cases, hence we can avoid Evans’s argument by adopting truth-value glut position. Of course, the truth-value glut approach has serious difficulties, but I conclude with sketching out a possibility to develop this approach in the free will debate via the introduction of probabilistic valuation.

Site‐specific phosphorylation of intermediate filament (IF) proteins on serine and threonine residues leads to alteration of the filament structure, in vitro and in vivo. Protein kinases involved in cell signaling and those activated in mitosis dynamically control spatial and temporal organization of intracellular IF phosphorylation. Thus, IF phosphorylation appears to be one of the most predominant strategies in coordinating intracellular organization of the IF network.

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)

For most death discharge patients, hospitals in Japan offer seeing-off services, a practice characteristic of Japanese culture. When a patient dies, nurses usually perform after-death procedures before transferring the body to the mortuary, where the nurses and doctors gather to provide the seeing-off service. This study was carried out to determine differences between the nurses’ and bereaved families’ opinions and thoughts regarding the seeing-off service. Semi-structured interviews were conducted with 17 nurses and 6 bereaved families . The interviews assessed: the (...) reasons why nurses provided seeing-off services; thoughts during the seeing-off service; impressions of the mortuary rituals; and the necessity for the seeing-off service. The results indicated that nurses expressed their courtesy and sense of appreciation during the seeing-off service, which was recognised as an important nursing role. In contrast, bereaved families felt thankful but also doubtful, particularly as regards the mortuary rituals. In light of the differences in perspective between nurses and families, it may be that the level of satisfaction with the seeing-off service is largely affected by the relationship between the family and the medical professionals before the patient's death. Our study also notes that Japanese people respect the dead body and treat it with care, reflecting the unique culture and customs of Japan. (shrink)
