Since sending explicit messages can be costly, people often utilize “what is not said,” i.e., informative silence, to economize communication. This paper studies the efficient communication rule, which is fully informative while minimizing the use of explicit messages, in cooperative environments. It is shown that when the notion of context is defined as the finest mutually self-evident event that contains the current state, the efficient use of informative silence exhibits the defining property of indexicals in natural languages. While the efficient (...) use of silence could be complex, it is also found that the efficient use of silence can be as “simple” as the use of indexicals in natural languages if and only if the information structure satisfies some centrality and dominance properties.

The origins of Japan's medical ideas, which are deeply rooted in its religion, culture and history, are not widely understood in medical societies of other countries. We have taken up the task of summarising this tradition here so that some insight can be gained into the unique issues that characterise the practice of medicine in Japan. We borrow from the sayings of Tohkaku Wada, a medical philosopher of late eighteenth-century Japan, for a look at Japanese medical tradition. Wada's medical thought (...) was very much reflective of the Buddhism, Zen, and swordsmanship that informed eighteenth-century philosophy in Japan. His central concepts were “chu” and “sei”, that is, complete and selfless dedication to the patient and the practice of medicine. This paper explores Wada's thought, explaining it mainly from the standpoint of Japanese traditional culture. (shrink)

Principles of Brain Evolution (Striedter 2005) places little emphasis on natural selection. However, one cannot fully appreciate the diversity of brains across species, nor the evolutionary processes driving such diversity, without an understanding of the effects of natural selection. Had Striedter included more extensive discussions about natural selection, his text would have been more balanced and comprehensive.

The target article about the origin and evolution of the isocortex triggers questions about unresolved issues that still need to be dealt with, including: (1) the evolutionary scenario of the origin of the lateral isocortex, (2) the expansion of the dorsal pallium in nonmammals, and (3) the heterogeneity of the anterior dorsal ventricular ridge.

In the era of natural law, the foundation of the law was grounded upon something beyond the law itself, i.e., external factors such as a higher authority, nature, or even the reason and ontological essence of man. According to this reasoning, man has in effect been clandestinely elevated to an equal plain with God and operates in the external realm, essentially observing the world „from outside“. Thus, any attempt to provide a basis for legal decisions by such external factors depends (...) on an „observer„ who assumes a privileged position with respect to the law and its ground. Lawyers continue to maintain this position of interpreting the positive law by seeking the ground of the law outside of itself, i.e., the external factors such as the „source of laws“, the „intention of the author“, and the “fundamental norm“, for example. While simultaneously claiming to be under the rule of law, they paradoxically take the position of an external „observer“ who perceives the law “from outside”. This position leads us to aporia, or an insoluble contradiction, regarding external grounds. This paper proposes a means by which to emerge from the above aporia. Using the theory of social systems as its basis, the legal system is viewed as a closed system and „the ground of the law“ is by no means derived from external factors; rather, it can be stated only through an internal operation within the closed system itself.

Spatial ability plays important roles in academic learning and everyday activities. A type of spatial thinking that is of particular significance to people's daily lives is cognitive mapping, that is, the process of acquiring, representing, and using knowledge about spatial environments. However, the skill of cognitive mapping shows large individual differences, and the task of spatial orientation and navigation poses great difficulty for some people. In this article, I look at the motivation and findings in the research into spatial knowledge (...) acquisition from an individual differences perspective. I also discuss major implications of the existence of large individual differences, particularly the possibility of improving cognitive mapping by training and adjusting navigation assistance to the wide variations in spatial aptitudes and preferences among people.

While directors’ task boundaries are usually ambiguous, some of their activities or behaviors clearly constitute their formal duties, whereas others are usually perceived as organizational citizenship behavior. Applying identity theory, we present a theoretical model that demonstrates one of the key drivers for directors to engage in OCB with a focus on their role identity. We argue that an individual director’s role identity is one of the key factors that motivate directors to engage in OCB. Furthermore, we propose that two (...) board-level contingencies, board capital, and informal board hierarchy order, can moderate the effect of directors’ role-identity salience on their OCB. That is, low levels of board capital and directors’ higher positions in a board’s informal hierarchy enhance directors’ motivation to engage in OCB. (shrink)

The ethics in an information society is discussed from the combined viewpoint of Eastern and Western thoughts. The breakdown of a coherent self threatens the Western ethics and causes nihilism. Francisco Varela, one of the founders of Autopoiesis Theory, tackled this problem and proposed Enactive Cognitive Science by introducing Buddhist middle-way philosophy. Fundamental Informatics gives further insights into the problem, by proposing the concept of a hierarchical autopoietic system. Here the ethics can be described in relation to a community rather (...) than a coherent self. The philosophical bridge between East and West is expected to solve the ethical aporia in the 21st century. (shrink)

Although we have learned much about the neuropsychological control of facial expressions of emotion, there is still much work to do. We suggest that future work integrate advances in our theoretical understanding of the roles of volition and consciousness in the elicitation of emotion and the production of facial expressions with advances in our understanding of its underlying neurophysiology. We first review the facial musculature and the neural paths thought to innervate it, as well as previous attempts at understanding the (...) neural control of facial expressions of emotion, focusing on the voluntary-involuntary dichotomy and studies of hemispheric specialization. In the second section, we discuss four major aspects of the psychology of facial expressions of emotion that have particular import to their neurophysiological substrates. We offer these as a starting point for a better integration of psychological and neurophysiological perspectives in considering the neuropsychological control of facial expressions of emotion.

This study examined how different components of working memory are involved in the acquisition of egocentric and allocentric survey knowledge by people with a good and poor sense of direction (SOD). We employed a dual-task method and asked participants to learn routes from videos with verbal, visual, and spatial interference tasks and without any interference. Results showed that people with a good SOD encoded and integrated knowledge about landmarks and routes into egocentric survey knowledge in verbal and spatial working memory, (...) which is then transformed into allocentric survey knowledge with the support of all three components, distances being processed in verbal and spatial working memory and directions in visual and spatial working memory. In contrast, people with a poor SOD relied on verbal working memory and lacked spatial processing, thus failing to acquire accurate survey knowledge. Based on the results, a possible model for explaining individual differences in spatial knowledge acquisition is proposed. (shrink)

Husserl attempted to found logics and language on intuition, and particularly perception. The relationship between logical language and intuition is therefore one of the fundamental themes of his phenomenology. Husserl regarded the two as sharing an isomorphic structure, and this article shows that this structure can be characterized as “mediality.” That is, the “meaning” of language appears by mediation of sound or script, while the “I” as person appears by mediation of the body. I will show furthermore that intuitions themselves (...) appear through the mediation of language, and interpret this idea of mediality in terms of the Japanese language. Guided by Husserl’s notion of Sprachleib, I will also attempt an analysis of the “bodily” function of Chinese script and onomatopeia as aspects of Sprachleib and show how the Sprachleib functions as a “cultural living body” that makes community possible.

There is a close relationship between Ashʿarism and Ḥanbalism since the emergence of Ashʿarism. However, they often conflicted with each other as they approached to religious matters from different perspectives. These conflicts were not only limited to theological discussions but also turned into social conflicts, which occasionally resulted with deaths. First massive events occurred in 429/1038 in Baghdād between Ashʿarites and Ḥanbalities. When Niẓām al-Mulk was appointed as vizier, the conflicts reached a peak. The apparent reason of the conflicts was (...) the theological controversy between these two sects. However, the rise of Ashʿarism, which was usually against Ḥanbalism, was the main reason of the social conflicts. Supports of the Ashʿarite thought by the leading statesmen of the era such as Niẓām al-Mulk and Ayyūbid sultans, and accusations of some Ashʿarite preachers about Ḥanbalities relying on this political support were also among the factors that led to these conflicts. Nevertheless, even if any accusation was not made, it occurred that the members of both sects resorted to violence in case of criticisms about their beliefs. This shows that the most important reason of the conflicts was sectarian fanaticism.Summary: Ashʿarism is the name of the sect that was formed around the ideas of Abū al-Ḥasan al-Ashʿarī. It is a continuation of Kullābism in terms of general thought system. Ashʿarism replaced Kullābism by the end of the 5th century of the Hijrah, and started to be called as an independent sect. It spread mostly among the Shāfiʿites and Mālikites in Iraq, Khurāsān, Damascus, Maghreb, and Yemen. When it was arrived to the last quarter of the 5th century, it became the common theological sect of most of Shāfiʿites and Mālikites. Bāqillānī (d. 403/1013), Ibn Fūrāk (d. 406/1015), and Abū Isḥāq al-Isfarāyīnī’s (d. 418/1027) efforts played an important role in rising of Ashʿarism in this period. In the following periods, contribution of the Seljuk vizier Niẓām al-Mulk (d. 485/1092) to Ashʿarism was massive by establishing the Niẓāmiyah Colleges to strengthen the Ashʿarites against the Hanafites in Khurāsān and against the Ḥanbalites in Baghdād. The Niẓāmiyah Colleges were donated by Niẓām al-Mulk to Shāfiʿite scholars for the mission of primarily limiting the influence Shīʿī thought. The condition of belonging to Shāfiʿites in waqfiyyah (endowment certificate) of the colleges provided some important advantages for Shāfiʿites and Ashʿarites. On the other hand, the Ayyūbids provided important contributions to Ashʿarites in the regions of Egypt, Damascus and Yemen. They worked for strengthening Ashʿarism during their ruling for two centuries. It was a state policy for the Ayyūbids to support Ashʿarism starting from the founder of the state, Ṣalāḥ al-Dīn al-Ayyūbī (d. 589/1193).This rapid rise of Ashʿarism led to a tense relationship between the Ashʿarites and the Ḥanbalites who became the most important representative of Aṣḥāb al-ḥadīth (people of the traditions of the Prophet) after the period of Miḥnah (period of religious persecution). Undoubtedly, the first respondents of these tense relations were Kullābite scholars. At the beginning of the 4th century of the Hijrah, Abū al-Ḥasan al-Ashʿarī became the natural inheritor of the Ḥanbalite reaction to the Kullābites. He conflicted with the Ḥanbalites because of his different approach on the debate regarding creation of the Qur’ān. Ḥanbalite reactions to Imam al-Ashʿarī continued after his death. When he died in Baghdād in 324/935, officials buried him secretly as they worried about Ḥanbalite attacks against his funeral. Hence, after his burial some Ḥanbalites tried to destroy his tomb several times. After Ashʿarī died, the first social events between the Ashʿarites and the Ḥanbalites took place in Iṣfahān, one of the most important cities of West Khurāsān, in the end of the 4th century of the Hijrah. The debate started around the question of whether the letters of the Qur’ān were created or uncreated between the Ḥanbalite scholar Ibn Mandah (d. 395/1005) and Ashʿarite scholar Abū Nuʿaym al-Iṣfahānī (d. 430/1038). This debate led to prolonged events between the supporters of these scholars. Abū Nuʿaym, saved his life from various attacks and finally he had to leave Iṣfahān.The tense relationships between the Ashʿarites and the Ḥanbalites reached the peak in the 5th century of the Hijrah. Many events occurred in Baghdād during this century. The discussion on interpretation of the revealed attributes of Allah turned into conflict between the two sides from time to time. The Ashʿarite scholars accused the Ḥanbalites with tashbih (affirming Allah’s similarity to humanity) and tajseem (anthropomorphism) by pointing at Abū Yaʿlā al-Farrā’s work titled Ibṭāl al-taʾwīl al-ṣifāt. The ʿAbbāsid caliphs generally supported the Ḥanbalites in this debate. For example, when al-Qāim bi-Amr Allāh re-published the famous declaration known as the Qādirī Creed in 433/1042, he proclaimed that rejection of the Ḥanbalite approach on the issue of the revealed attributes of Allah would be regarded as a cause of blasphemy. The paper was read in a meeting where several scholars from various sects were present. It was signed firstly by Ashʿarite scholar Abū al-Ḥasan ʿAli ibn ʿUmar al-Qazwīnī (d. 442/1051). However, he was one who had criticized Ibṭāl al-taʾwīl al-ṣifāt in 429/1038, which caused conflicts in society at that time. This shift in his position is remarkable as it shows that the declaration was primarily response to him.In the middle of the 5th century of the Hijrah, Ashʿarite scholar al-Khatīb al-Baghdādī (d. 463/1071) became a victim of the tension between the Ashʿarites and Ḥanbalites. Khatīb had protection of vizier Ibn al-Muslima and under his protection he lectured on Hadith in the Mansur Mosque. However, after the death of the vizier, he was subjected to harassment of the Ḥanbalites because of some expressions in his work titled Tarīkh Baghdād. So much so that he began to worry about his life, thus he had to leave Baghdād and went to Damascus in 451/1059.The tense relations between the Ashʿarites and the Ḥanbalites reached the summit in the period of Niẓām al-Mulk who was the vizier of Seljuk Empire. In fact, some events resulted with deaths. For example, in the events of 469/1076, which lasted years, the Ḥanbalites attacked Ashʿarite scholar Abū Naṣr ibn ʿAbd al-Karīm al-Qushayrī (d. 514/1120) who accused them with tashbeeh and tajseem. As a result, around twenty people died during these events. The gradual rise of the Ashʿarite thought with the support of Niẓām al-Mulk and abusive discourses of some Ashʿarite scholars who relied on this support can be mentioned among the basic reasons of the events at that time.After the death of Niẓām al-Mulk in 485/1092, for a long time there was no serious event between the Ashʿarites and the Ḥanbalites. In the middle of the 6th/12th century, the relations started to become tense again in the regions of Egypt, Damascus, and Yemen under the Ayyūbid dynasty. In addition to these places, various events occurred in Khurāsān region, in cities such as Marw. Nevertheless, unlike some previous events, the current tensions were not against a whole sect but only targeted some individual scholars. Moreover, unlike the previous periods, oppressed and victimized people were mostly Ḥanbalite scholars this time. No serious events took place between two sects after this period. Therefore, it can be said that their struggle to dominate society led to the above-mentioned events. (shrink)

Knowledge modal formulas are interpreted by a universal modal world in the hypersets universe [A]. This remedies the limitation of the interpretation of knowledge formulas by a tower of modal worlds in the well founded universe [F], where each world can interpret only a portion of knowledge modal formulas.

Does a penny per month constitute a Basic Income? Were that penny to be paid individually, universally, and unconditionally, the answer would be ‘yes’, following the definition of Basic Income given by some of its leading advocates, be it organisations like the Basic Income Earth Network or prominent scholars such as Philippe Van Parijs. Some might be puzzled as to how this could be ‘a capitalist road to communism’, or give us ‘freedom as the power to say no’, both of (...) which have been advocated by prominent researchers. The purpose of this paper is not to argue for or against their definition, but rather to situate it historiographically, enabling fruitful discussion. The paper will show how there was a widely shared assumption in the 1970s and 80s, at the early stages of both academic articulations and public discussion, that Basic Income comes with some notion of a threshold or level to be taken as a minimum or as adequate. The paper goes on to outline three issues that arise once the concept of a threshold is dropped from the definition. Examined in addition are five justifications for doing so. Much like any other idea, the concept of Basic Income is a social construct. By situating it here within a historical perspective, we wish to facilitate academic discussion regarding both the achievements and erasures that have occurred as a consequence of the concept’s academic refinement—refinement that is in itself majorly indebted to BIEN and Van Parijs.

In this paper, I discuss the problems of ``order in social situations'' using a computer simulation of iterated N -person prisoners' dilemma game. It has been claimed that, in the case of the 2 -person prisoners' dilemma, repetition of games and the reciprocal use of the ``tit-for-tat'' strategy promote the possibility of cooperation. However, in cases of N -person prisoners' dilemma where N is greater than 2, the logic does not work effectively. The most essential problem is so called ``sanctioning (...) problems''. In this paper, firstly, I discuss the ``sanctioning problems'' which were introduced by Axelrod and Keohane in 1986. Based on the model formalized by Axelrod, I propose a new model, in which I added a mechanism of players' payoff changes in the Axelrod's model. I call this mechanism norm-internalization and call our model `` norm-internalization game ''. Second, by using the model, I investigated the relationship between agents' norm-internalization (payoff-alternation) and the possibilities of cooperation. The results of computer simulation indicated that unequal distribution of cooperating norm and uniform distribution of sanctioning norm are more effective in establishing cooperation. I discuss the mathematical features and the implications of the results on social science. (shrink)

This paper studies a sender-receiver game in which both players want the receiver to choose the state-optimal action. Before observing the state, the sender observes a “contextual signal,” a payoff-irrelevant signal that correlates with states and is imperfectly shared with the receiver. Once the sender observes the state, the sender sends a message to the receiver, incurring a small messaging cost. It is shown that there is no miscommunication in any efficient equilibrium if the messaging cost is uniform or contextual (...) information is poorly shared between players. However, if the messaging costs are different between some messages, and contextual information can affect the probability ranking of states and is shared reasonably well, any efficient equilibrium that favors the sender exhibits miscommunication. Furthermore, the messages that cause miscommunication can be coarse or ambiguous, depending on how well players share contextual information. (shrink)

When an agent’s motivation is sensitive to how his supervisor thinks about the agent’s competence, the supervisor has to take into account both informational and expressive contents of her message to the agent. This paper shows that the supervisor can credibly express her trust in the agent’s ability only by being un- clear about what to do. Suggesting what to do, i.e., “directives,” could reveal the supervisor’s “distrust” and reduce the agent’s equilibrium effort level even though it provides useful information (...) about the decision environment. There is also an equilibrium in which directives are neutral in expressive content. However, it is shown that neologism proofness favors equilibria in which directives are double- edged swords.

Human beings express affinity (Shinwa‐kan in Japanese language) in communicating transactive engagements among healthcare providers, patients and healthcare robots. The appearance of healthcare robots and their language capabilities often feature characteristic and appropriate compassionate dialogical functions in human–robot interactions. Elements of healthcare robot configurations comprising its physiognomy and communication properties are founded on the positivist philosophical perspective of being the summation of composite parts, thereby mimicking human persons. This article reviews Mori's theory of the Uncanny Valley and its consequent debates, (...) and examines "Uncanny" relations with generating healthcare robot conversational content with artificial affective communication (AAC) using natural language processing. With healthcare robots provoking influential physical composition and sensory expressions, the relations in human–healthcare robot transactive engagements are argued as supportive of the design and development in natural language processing. This implies that maintaining human–healthcare robot interaction and assessing the eeriness situations explained in the Uncanny Valley theory are crucial positions for healthcare robot functioning as a valuable commodity in health care. As such, physical features, language capabilities and mobility of healthcare robots establish the primacy of the AAC with natural language processing as integral to healthcare robot–human healthcare practice.

BackgroundEmotional regulation is important for adolescents’ adaptive development. Preventive interventions for anxiety and depression are necessary for reducing the development of disorders later in life, and emotional regulation is a potentially relevant factor.ObjectiveWe investigated the effects of a mindfulness-based psychological education and prevention program [the Mindfulness and Awareness Program ] on the mental health of junior high school students in Japan.MethodsOur MAP primarily focused on mindfulness meditation to improve emotional regulation, thereby reducing depression and anxiety. The MAP comprised eight sessions (...) administered by a school counselor in a school setting. All participants were 12–13-year-old adolescents from nine classes in two Japanese schools. The program was provided to the intervention group, wherein students were educated on emotional expression, emotional cognition, and emotional regulation. The control group received regular school counseling services.ResultsCompared with the control group, the intervention group showed significant improvement in emotional regulation and a decrease in depression and generalized anxiety. The effect was greater at the follow-up assessment than at the immediate post-intervention assessment, and greater in female students.ConclusionOur mental health prevention program exhibited efficacy in reducing depression and anxiety and enhancing emotional regulation in early adolescence. Further, it appeared to be more effective for female adolescents. (shrink)

The aim of this paper is to shed light on our understanding of large scale properties of infinite strings. We say that one string $\alpha $ has weaker large scale geometry than that of $\beta $ if there is color preserving bi-Lipschitz map from $\alpha $ into $\beta $ with small distortion. This definition allows us to define a partially ordered set of large scale geometries on the classes of all infinite strings. This partial order compares large scale geometries of (...) infinite strings. As such, it presents an algebraic tool for classification of global patterns. We study properties of this partial order. We prove, for instance, that this partial order has a greatest element and also possess infinite chains and antichains. We also investigate the sets of large scale geometries of strings accepted by finite state machines such as Büchi automata. We provide an algorithm that describes large scale geometries of strings accepted by Büchi automata. This connects the work with the complexity theory. We also prove that the quasi-isometry problem is a $\Sigma _2^0$ -complete set, thus providing a bridge with computability theory. Finally, we build algebraic structures that are invariants of large scale geometries. We invoke asymptotic cones, a key concept in geometric group theory, defined via model-theoretic notion of ultra-product. Partly, we study asymptotic cones of algorithmically random strings, thus connecting the topic with algorithmic randomness. (shrink)

The paper explores conceptual approaches to business ethics from the Japanese tradition and their potential to enhance our global approach to social and environmental sustainability, including discussion of a framework for understanding the embeddedness of the business in society. As globalization and economic and sociopolitical challenges proliferate, the nature of the connections between the USA and Asia is more important than ever. Following an expressed “pivot” or “rebalance” to Asia and the current nebulous alliances, we hope to raise the profile (...) of Japan’s potential to shape the conception and practice of business in society. We explore attempts to offer a universal business ethic, intended as guidance for businesses globally, and examine contributions of Japanese thought to these frameworks. Considering the traditional approaches of sanpoyoshi, or tri-directional welfare in business transactions, kyosei, which can mean “living and working together for the common good”, and mottainai, or “grateful and sustainable consumption,” the research explores the relationships between the private sector, government, and civil society. Further, we examine the related notion of moralogy, which has been described as a virtue-based stakeholder approach to business. We suggest that these concepts merit promoting the conception of the “homo socio-economicus” model to replace the prevailing “homo economicus” model that threatens what sound business should be. Through interviews with Japanese scholars and practitioners and exploration of Japanese cultural traditions, we present an overview of these approaches. With this perspective, we cite the case of the Tōhoku earthquake and Fukushima nuclear disaster as one illustrative example. We hope that this understanding of the embeddedness of business in society based on Japanese traditions and experience can contribute to a global conception of the role of business in society, relevant to the USA as well. Our goals are to contribute to existing discussions of Japanese business ethics and relevance to a global perspective, and to inspire ongoing exploration of applications of these ideas in teaching and scholarship.

To preserve postoperative brain function, it is important for neurosurgeons to fully understand the brain's structure, vasculature, and function. Intraoperative high-frequency electrical stimulation during awake craniotomy is the gold standard for mapping the function of the cortices and white matter; however, this method can only map the “focal” functions and cannot monitor large-scale cortical networks in real-time. Recently, an in vivo electrophysiological method using cortico-cortical evoked potentials induced by single-pulse electrical cortical stimulation has been developed in an extraoperative setting. By (...) using the CCEP connectivity pattern intraoperatively, mapping and real-time monitoring of the dorsal language pathway is available. This intraoperative CCEP method also allows for mapping of the frontal aslant tract, another language pathway, and detection of connectivity between the primary and supplementary motor areas in the frontal lobe network. Intraoperative CCEP mapping has also demonstrated connectivity between the frontal and temporal lobes, likely via the ventral language pathway. Establishing intraoperative electrophysiological monitoring is clinically useful for preserving brain function, even under general anesthesia. This CCEP technique demonstrates potential clinical applications for mapping and monitoring large-scale cortical networks. (shrink)

This paper will deal with the relationship between 'life' (Leben) and the 'life-world' (Lebenswelt) 1 as we find these concepts in the writings of Husserl's last years. The emphasis will be upon elucidating this relation- ship from the transcendental point of view. It is well known that Husserl initially introduced the concept of the life-world into his philosophy in connection with the problem of founding the sciences: accordingly, most studies up to date have dealt with the concept within this context (...) - that is, as part of the program for founding the sciences. However, it is important to remember that the life-world is also, for Husserl, a 'way to the transcendental reduction', and as such, can be ultimately clari- fied only by following this way to its end, and by comprehending it in its relationship to transcendental subjectivity. In his later years, Husserl came to think of the 'way of being' (Seinsweise) of transcendental sub- jectivity as 'world-experiencing-life' (welterfahrendes Leben). Thus it is my view that the problem of the 'life-world' is intimately related to that of 'life', and must necessarily be treated in the context of that rela- tionship. (shrink)
