Firstly I characterize Simple Partial Logic (SPL) as the generalization and extension of a certain two-valued logic. Based on the characterization I present two definitions of validity in SPL. Finally I show that given my characterization these two definitions are more appropriate than other definitions that have been prevalent, since both have some desirable semantic properties that the others lack.

With the development of assisted reproductive technologies, medical, ethical, legal, and social issues have arisen that did not exist when natural conception was the only means of childbirth. In Japan, men tend to believe that assisted reproductive technologies are not directly related to them, with the literature showing that men are often reluctant to be involved in fertility treatment processes. To better understand this situation, this study analyzes the role of male consent during assisted reproductive technology procedures in Japan. First, (...) we examined Japanese court cases that dealt with issues related to male consent during assisted reproductive technology procedures and identified three situations in which problems related to male consent during such procedures may arise. Next, we analyzed the background of such issues and the implications of the lack of consent regarding men’s reproductive rights. Finally, we explored the need for legislation on assisted reproductive technologies. The study concludes that discussions on the scope of male partner rights in assisted reproductive technology procedures are key for minimizing unnecessary conflict between partners, thus ensuring both the rights of women who wish to have children and the welfare of their children.

Currently in Japan, discontinuing an invasive mechanical ventilator (IMV) is illegal; therefore IMV-related decision making is a crucial issue. This study examined IMV decision-making factors and psychological conflict in 50 patients with amyotrophic lateral sclerosis. The Herth Hope Index was used for the assessment of pre- and post-IMV conflict. Interviews identified some decision-making factors: patient’s decision, patient’s and family’s mutual decision, family’s decision, and emergency-induced without patient’s or family’s consent. Participants who experienced no IMV-related regret received sufficient prior IMV education (...) from physicians and nurses, and time for reflection and family consultation. Their hope was similar to their pre-onset levels. Patients who received no prior IMV education accepted treatment as a natural progression. Their hope levels were lower than pre-onset. Those who received only a brief prior IMV explanation rejected the ventilator, experiencing regret if they were given an emergency IMV. Their hope levels were among the lowest. However, some of these patients managed to overcome their regret through being helped by nurses. Sufficient physician explanation and nursing advocacy for autonomous patient decision making are critical for improving hope in this patient group. (shrink)

現代の物質像の根本的変容に対し、アリストテレス以来の実体主義を洗練、実在の本性に迫る包括的形而上学理論の構築。.

In this paper, I argue that later Nishida's analysis of self-awareness (jikaku) provides a new perspective on the nature of self-awareness as understood in the philosophical literature today. I argue that the contemporary literature deals with two kinds of self-awareness; the higher-order theory understands self-awareness to be an objectified awareness and the phenomenological tradition generally understands self-awareness to be, at least primarily, a non-objectified awareness. In light of this, I first give an account of Nishida's ?acting-intuition? with reference to the (...) ?historical body.? Then I argue that later Nishida's analysis of self-awareness depicts the inadequacy of the two kinds of self-awareness as both being stuck in the subject-object dichotomy which, according to Nishida, is but one mode of experience, namely the mode of difference. Nishida provides an account that ultimately foregrounds the experiential mode of unity that negates any sense of differentiation between the subject and object. (shrink)

In this paper, we first enumerate the problems that humans might face with a new type of technology such as robots with artificial intelligence (AI robots). Robotics entrepreneurs are calling for discussions about goals and values because AI robots, which are potentially more intelligent than humans, can no longer be fully understood and controlled by humans. AI robots could even develop into ethically “bad” agents and become very harmful. We consider these discussions as part of a process of developing responsible (...) innovations in AI robotics in order to prevent catastrophic risks on a global scale. To deal with these issues, we propose the capability-effectual approach, drawing on two bodies of research: the capability approach from ethics, and the effectual process model from entrepreneurship research. The capability approach provides central human capabilities, guiding the effectual process through individual goals and aspirations in the collaborative design process of stakeholders. More precisely, by assuming and understanding correspondences between goals, purposes, desires, and aspirations in the languages of different disciplines, the capability-effectual approach clarifies both how a capability list working globally could affect the aspirations and end-goals of individuals, and how local aspirations and end-goals could either energise or limit effectual processes. Theoretically, the capability-effectual approach links the collaboration of stakeholders and the design process in responsible innovation research. Practically, this approach could potentially contribute to the robust development of AI robots by providing robotics entrepreneurs with a tool for establishing a permissible action range within which to develop AI robotics.

We propose protein localization dependent signal activation (PLDSA) as a model to describe pre‐existing protein partitioning between the cytosol, and membrane surface, as a means to modulate signal activation, specificity, and robustness. We apply PLDSA to explain possible molecular links between type II diabetes mellitus (T2DM) and Alzheimer's disease (AD) by describing Ca+2‐mediated interactions between the Src non‐receptor tyrosine kinase and p52Shc adaptor protein. We suggest that these interactions may serve as a contributing factor to disease development and progression. In (...) particular, we propose that signaling response is regulated, in part, by Ca+2‐mediated partitioning of lipid‐bound and soluble forms of Src and p52shc. Thus, protein‐protein interactions that drive signaling in response to extracellular ligand binding are also mediated by partitioning of signaling proteins between membrane‐bound and soluble populations. We propose that PLDSA effects may explain, in part, the evolutionary basis of promiscuous protein interaction domains and their importance in cellular function. (shrink)

Diese Arbeit ist eine Interpretation zum Kapitel Das Gewissen der Phänomenologie des Geistes. Dabei bemüht die Autorin weder philologische noch sozialwissenschaftliche Methoden, sondern wendet sich direkt an das Denken Hegels. Nach Hegel wird in diesem Kapitel der Unterschied zwischen dem allgemeinen Ich und dem eigenen Ich unter Beweis gestellt.

Previous research has shown that although infants follow the gaze direction of robots, robot gaze does not facilitate infants’ learning for objects. The present study examined whether robot gaze affects infants’ object learning when the gaze behavior was accompanied by verbalizations. Twelve-month-old infants were shown videos in which a robot with accompanying verbalizations gazed at an object. The results showed that infants not only followed the robot’s gaze direction but also preferentially attended to the cued object when the ostensive verbal (...) signal was present. Moreover, infants showed enhanced processing of the cued object when ostensive and referential verbal signals were increasingly present. These effects were not observed when mere nonverbal sound stimuli instead of verbalizations were added. Taken together, our findings indicate that robot gaze accompanying verbalizations facilitates infants’ object learning, suggesting that verbalizations are important in the design of robot agents from which infants can learn. Keywords: gaze following; humanoid robot; infant learning; verbalization; cognitive development. (shrink)

Research in basic and clinical neuroscience of music conducted over the past decades has begun to uncover music’s high potential as a tool for rehabilitation. Advances in our understanding of how music engages parallel brain networks underpinning sensory and motor processes, arousal, reward, and affective regulation, have laid a sound neuroscientific foundation for the development of theory-driven music interventions that have been systematically tested in clinical settings. Of particular significance in the context of motor rehabilitation is the notion that musical (...) rhythms can entrain movement patterns in patients with movement-related disorders, serving as a continuous time reference that can help regulate movement timing and pace. To date, a significant number of clinical and experimental studies have tested the application of rhythm- and music-based interventions to improve motor functions following central nervous injury and/or degeneration. The goal of this review is to appraise the current state of knowledge on the effectiveness of music and rhythm to modulate movement spatiotemporal patterns and restore motor function. By organizing and providing a critical appraisal of a large body of research, we hope to provide a revised framework for future research on the effectiveness of rhythm- and music-based interventions to restore and train motor function.

In this essay I present the philosophy of Nishida Kitarō, the father of the Kyoto School tradition, as an alternative version of transcendental philosophy. While following the steps of Kant and Husserl in important ways, Nishida attempts to take the transcendental approach even further, finally leaving us with a different view of reality that is neither realist nor idealist, but, rather, radically realist. I call this radical transcendental position, “awakened realism”. Due to word limitations, I can only set the stage (...) for further discussion on what kind of implication this may have for transcendental philosophy. But if I succeed in making my presentation clear enough, it should naturally ignite discussion on how far we can radicalize transcendental philosophy without making it into something else. (shrink)

In most contexts, emotional support is crucial for the well-being of low-income single women and their children. Support from women may be especially important for single mothers because of precarious ties to their children’s fathers, the prevalence of extended matrifocal living arrangements, and gendered norms that place men as providers of financial rather than emotional support. However, in contexts marked by economic insecurity, spatial dispersion of families, and changing gender norms and kinship obligations, such an expectation may be problematic. Applying (...) theories of emotional capital and family bargaining processes, we address three questions: What is the gender composition of emotional support that single mothers receive? How does gender composition change over time? Does the gender composition of emotional support affect the self-reported stress of single mothers? Drawing on data from a unique data set on 462 low-income single mothers and their kin from Nairobi, Kenya, we uncover three key findings. One, whereas the bulk of strong emotional support comes from female kin, about 20 percent of respondents report having male-dominant support networks. Two, nearly 30 percent of respondents report change favoring men in the composition of their emotional support over six months. Three, having a male-dominant emotional support network is associated with lower stress. These results challenge what is commonly taken for granted about gender norms and kinship obligations in non-Western contexts. (shrink)

Comparative studies of primates indicate that humans have evolved unique motivations and cognitive skills for sharing emotions, experiences, and collaborative actions. Given the characteristics of music, the music and social bonding hypothesis by Savage et al. fits this view. Within a cross-species approach, predispositions not observed in current communication system may contribute to a better understanding of the biological roots of human musicality.

Although chimpanzees have been reported to understand to some extent others' visual perception, previous studies using food requesting tasks are divided on whether or not chimpanzees understand the role of eye gaze. One plausible reason for this discrepancy may be the familiarity of the testing situation. Previous food requesting tasks with negative results used an unfamiliar situation that may be difficult for some chimpanzees to recognize as a requesting situation, whereas those with positive results used a familiar situation. The present (...) study tested chimpanzees' understanding of others' attentional states by comparing two requesting situations: an unfamiliar situation in which food was put on a table, and a familiar situation in which chimpanzees requested food held by an experimenter. Chimpanzees showed evidence of understanding the experimenter's attentional variations and the role of eye gaze only in the latter task. This suggests that an unfamiliar requesting situation may keep subjects from expressing their understanding of others' attentional states even though they are sensitive to them.

With our state-guaranteed or internationally recognized human rights, liberalism is rather a common basis of political discussion today. John Rawls’s theory of justice, which set a framework for liberal theory of justice in the last decades of the twentieth century, is notably contractarian. Martha Nussbaum, although claiming to be a neo-Aristotelian, argues that her capabilities approach (hereafter CA) can upgrade the liberal theory of justice, particularly that of political liberalism, to deal with unsolved problems of justice, namely, disability, nationality, and (...) species membership. However, this paper argues that her proposal issuccessful only when her CA-based theory proves its affiliation with political liberalism in more detail. As defined by Rawls, political liberalism produces “free-standing” political conceptions and rejects any metaphysical or religious ideas. It halts conceptions of justice that promote conceptions of good derived from particular comprehensive doctrines. I do not believe a mere convergence between CA and contractarianism is sufficient enough to secure the rational acceptability of her CA-based theory. I suggest that if she wishes to maintain her CA-based theory’s being politically liberal, she either has to prove more of the public, in particular the global public, acceptability of her intuitive ideas of human dignity without relying on her intuitions or alter the meaning of political liberalism itself so that it allows a room for some sort of comprehensive doctrine.

Iris Marion Young’s social connection model of responsibility faces one difficulty when dealing with a non-ideal case where actors, especially victims, lack what I call “capability for responsibility”. Without taking this problem into consideration, Young’s model could be criticized for blaming the victim for not taking their responsibility for political Justice. In this paper, I address this question by examining a case study taken from Japan where society is deeply structured in a mode that oppresses women. The first sections point (...) out that Young’s model overlooks the importance of agents for political justice while trying not to blame anyone. In the second sections I will introduce the idea of the “capability for responsibility” to connect the analytical part and the prescriptive part of her model as a theory of justice, arguing that actors’ engagement in self-examination through collective action is necessary for the enhancement of their capability for responsibility.

Łukasiewicz has often been criticized for his motive for inventing his three-valued logic, namely the avoidance of determinism. First of all, I want to show that almost all of the critcism along this line was wrong. Second I will indicate that he made mistakes, however, in constructing his system, because he had other motives at the same time. Finally I will propose some modification of his system and its interpretation which can attain his original purpose in some sense.

Simple partial logic (=SPL) is, broadly speaking, an extensional logic which allows for the truth-value gap. First I give a system of propositional SPL by partializing classical logic, as well as extending it with several non-classical truth-functional operators. Second I show a way based on SPL to construct a system of tensed ontology, by representing tensed statements as two kinds of necessary statements in a linear model that consists of the present and future worlds. Finally I compare that way with (...) other two ways based on Łukasiewicz’s three-valued logic and branching temporal logic. (shrink)

Firstly I define a hole as a dependent matter-less endurant, which is a little modification of Casati and Varzi’s definition. Adopting this definition, holes seem to invite three problems about causation: (1)causal closure, (2)ungrounded disposition and (3)causal overdetermination. I will defend my definition against all these problems by showing that holes are limiting cases of physical endurants rather than their opposition and that they have causal powers in a broad sense.

In this paper I give consideration to some apparent impossibilities for the time travelers to the past. After criticizing the views of D. Lewis and K. Vihvelin, I will show in what sense they are really impossible.

Recently, Bourne constructed a system of three-valued logic that he supposed to replace Łukasiewicz’s three-valued logic in view of the problems of future contingents. In this paper, I will show first that Bourne’s system makes no improvement to Łukasiewicz’s system. However, finding some good motivations and lessons in his attempt, next I will suggest a better way of achieving his original goal in some sense. The crucial part of my way lies in reconsidering the significance of the intermediate truth-value so (...) as to reconstruct Łukasiewicz’s three-valued logic as a kind of extensional modal logic based on partial logic.

M. Johnston proposed an adverbialist solution to the problem of intrinsic change of enduring things. D. Lewis interpreted it as a way of tensing the copula. In his view, it has the defect of replacing having a property simpliciter by standing in a triadic relation to a property and a time, and so is threatened by Bradley’s Regress. I agree with Lewis on requiring having a property to be non-relational, while I disagree with him on restricting it to having simpliciter. (...) I tense the copula non-relationally and yet more seriously than Johnston, by characterizing tense as a copulative de re modality concerning endurance, which I relate to R. Taylor’s ‘pure becoming’. I will show that my way gives a better solution to the problem of intrinsic change than those by other endurantists, because of its close connection to an account of tense, endurance and becoming.

Casati and Varzi have developed a theory of boundary based on extensional mereotopology and the distinction between fiat and bona fide boundaries. Firstly, I point out some problems in their theory that are related to the contact of bodies. Next, I propose a way of classification of boundaries into four kinds based on substance ontology and an alternative distinction between potential and actual boundaries. Finally, I will show that my way of classification makes it possible to solve the problems above.

There are two types of theories regarding many worlds: one is modal, while the other is temporal. The former regards reality as consisting of many possible worlds, while the latter holds that reality consists of many momentary worlds, which are usually called moments. I compare these two theories, paying close attention to the concept of transworld identity and compare trans-possible world identity with trans-momentary world identity (or transmoment identity). I characterize time from the point of many-worlds view, believing this to (...) be one of the best ways of grasping the reality of time. First, I show that there is reason to adopt the many-worlds view because transworld identity is meaningful for both of them, while it is not for space. Second, I argue that transmoment identity is different from transpossible world identity concerning reality. The former is a realistic relation, while the latter is not. Thus, I find that the reality of time is in the relation of transmoment identity. Such a view, I contend, has merit on the basis that it recognizes the reality of time in a sense that is not true of space. (shrink)

Nurses’ turnover intention has become a concern for medical institutions because nurses are more needed than ever under the prevalence of COVID-19. This research sought to investigate the effects of the four dimensions of organizational justice on COVID-19 frontline nurses’ turnover intention through the mediating role of job engagement. We also tested the extent to which perceived job alternatives could moderate the relationship between job engagement and turnover intention. This descriptive cross-sectional study used an online survey to collect data from (...) 650 frontline nurses working in appointed hospitals in Jiangsu province, China. Hierarchical regression was used to analyze the hypothesized relationships. Findings revealed that all organizational justice components significantly influenced job engagement and turnover intention. Job engagement also significantly affected nurses’ turnover intention and mediated the relationships between organizational justice components and turnover intention. Besides, perceived job alternatives moderated the relationships between job engagement and turnover intention. The implications of this study include demonstrating that healthcare authorities should respect human rights through effective organizational justice as this approach could encourage nurses to appreciate their job and be more devoted to staying and achieving their institutional duties, especially under challenging circumstances.

In my paper 'Validity in Simple Partial Logic'(2002) I made comparison between several definitions of validity in Simple Partial Logic(SPL) and adopted two of them as most appropriate.

Then, based on the characterization of Partial Semantics, I will show that we (...) can regard SPL as a logic of extensional alethic modality. (shrink)
