The importance of learning and categorizing social objects and events has become widely acknowledged over a couple of decades. Although findings from field studies have suggested that non-human animals have sophisticated abilities to recognize social objects, there is relatively little experimental evidence on this issue. Some studies have revealed animals’ excellent skills for discriminating visual and auditory social stimuli. However, because of perceptual resemblances among stimuli, it is still not clear that they recognize these objects with conceptual mechanisms that are (...) independent of the perceptual characteristics of the stimuli. At the same time, whether their concepts have an aspect of transferring information from one modality to another has not received much attention. This paper advocates approaches to a cross-modal aspect of concepts as a new framework to solve these problems, and introduces the latest studies on cross-modal representations of social objects in non-humans.

Grodzinsky's general approach to the neuroscience of language is interesting, but the evidence currently available has problems with pragmatic infelicity in experiments involving Japanese scrambling and the interpretation of experimental results on Japanese indirect passives. I will suggest a more direct way of testing the Trace-Deletion Hypothesis (TDH).

The famous Japanese novelist offers his personal interpretation of a classic work on samurai ethics, everyday life, and spiritual salvation.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 20 (2000) 59-69 [Access article in PDF] Buddhist Views on Ritual Pactice Protestant Character of Modern Buddhist Movements Yukio MatsudoUniversity of HeidelbergWhat is the relationship between ritual and ethical activities in Nichiren Buddhism, as practiced in the Soka Gakkai (SG)? SG is a lay Buddhist organization which is, as such, involved extensively in secular affairs, specifically in the field of educational, cultural, social, and peace-promoting programs. (...) The question is, therefore, not at all whether there is a connection of religious practice and ethical activities. Rather it begs an explanation regarding its ideological background. In this respect a further reflection on a metareflection level would be useful to clarify the "modern" character of SG, which may be discussed in relation to Christian Protestantism since it has been regarded as a spiritual background for the formation of modern ethos such as individualism, egalitarianism, and social engagement. Thus, I will depict the fundamental feature of Nichiren Buddhism as "reformative Buddhism," which makes the practice of Buddhism congruent with "modern" understanding of religious roles in daily life as well as social engagement. On the other hand, I will also discuss some problems being inherent to the Western acculturation of the reformed and "engaged Buddhism." 1 The Ethical Activities of the SG in the World Ethical and Social Aspects of the Movement It is generally well known that the lay Buddhist organization, SG, as a whole has initiated wide and multifaceted activities even in an international level in order to transform its religious ideals into social reality, specifically in the field of educational, cultural, social, and peace-promoting programs. For this purpose it established educational institutes ranging from kindergartens to universities as well as research [End Page 59] institutes such as the Institute of Oriental Philosophy (founded 1961), the Boston Research Center for the 21st Century (founded 1993), the Toda Institute for Global Peace and Policy Research (founded 1996), and other centers for ecological researches. For promoting mutual respect and understanding through cultural expressions and exchanges several institutes have been established, like the Min-On Concert Association (founded 1963), the Tokyo Fuji Art Museum (founded 1991), and La Maison Littéraire de Victor Hugo in Bièvre, France (founded 1992). On a global level, its political involvement is, for a large part, situated as a NGO in the frame of the UNO and the UNESCO. With the help of the UNO, SG has organized all over the world expositions translating its concerns for peace, e.g., "Nuclear War: Threat to our World" and "War and Peace." With the Simon Wiesenthal Center it organized an exhibition "The Courage to Remember: Anne Frank and the Holocaust Exhibition." The issue of human rights is another of its major concerns. Commemorating the forty-fifth anniversary of the United Nations' adoption of the Universal Declaration of Human Rights, SG held an exhibition entitled "Toward the Century of Humanity: An Overview of Human Rights in Today's World" at the UN office in Geneva. Also, money received from fund-raising activities has been donated to the Office of the United Nations High Commissioner for Refugees and related agencies to provide medical supplies and food, and to support educational programs in the areas concerned. To expose the horrors of war, SG has also published life histories written by members about their sufferings in war: "Women against War," "Cries for Peace," and "Peace is our Duty." Segmental Differentiation of Organizational Structure To meet the requirements of functional differentiation of today's modern societal life SG is organized in a segmental and hierarchical structure. The basic structure is the regional units, organized in a hierarchical model, and all members are integrated "in each group" in their residence area. At the same time each member belongs to a specific "division" which is organized according to gender, age, and occupation. There are the four divisions of men, women, young men, and young women. Additionally there are divisions for school boys and girls, university students, as well as divisions according to occupation such as artists, lawyers, medical doctors, academics, and so on. These divisional differentiations reflect the need... (shrink)

Free will in intentional consciousness is exposed to skeptics since it was found that subconscious neural activities, what is called readiness potential, precedes the intention to an action. The question of whether free will is an authentic illusion has been argued not only in psychology but physics and philosophy. Most of scientists, however, think that the intentional consciousness who believes to have his/her own free will, is determined by readiness potential in advance, and that free will cannot coexist with determinism. (...) We here point out that knowing to be determined in advance cannot be verified till local event at a local site can be known from a different local site without disturbing the event. That is the assumption of locality. We here show that determinism, free will and locality are three essential elements in consciousness, and show that they constitute trilemma. The fact that one of three elements must be abandoned can lead to three types of consciousness. Absence of free will can constitute type I consciousness which is consistent with symptoms in autism spectrum disorder such as weakened theory of mind. Absence of determinism can constitute type II consciousness which is consistent with symptoms in schizophrenia such as thought insertion, self-other integration. Absence of locality can constitute type III consciousness which is consistent with typical people. We can find the entanglement of intentional consciousness with unconsciousness including readiness potential only in type III consciousness. Finally, we show that sense of agency and free will cannot be established until consciousness as an entanglement is implemented. (shrink)

Floridi’s infosphere consisting of informational reality is estimated and delineated by introducing the new notion of Typ-Ken, an undifferentiated amalgam of type and token that can be expressed as either type or token dependent on contingent ontological commitment. First, we elaborate Floridi’s system, level of abstraction (LoA), model, and structure scheme, which is proposed to reconcile ontic with epistemic structural reality, and obtain the duality of type and token inherited in the relationship between LoA and model. While we focus on (...) the ontological commitment that can negotiate and emphasize the discrepancy between type and token, we show that most research focusing on different hierarchical layers (type and token) has converged onto the flattened perspective of type and token to clarify the role of ontological commitment. We propose the idea of Typ-Ken to avoid this flattening. In addition, we elaborate Taddeo and Floridi’s criticism of approaches to the symbol grounding problem and show that their criticism based on the zero semantical commitment condition is specific to the agents affected by the flattening. We then take bird flocks as a metaphor for the living infosphere as if it had one mind. The knowledge recently yielded by image analysis indicates that it is difficult for previous flock models based on agents equipped with the flattening of local (token) and global (type) to show the special feature of a flock of the scale-free proportion (SFP). We show here that agents based on the Typ-Ken can reveal the SFP, which is the essential characteristic of the living infosphere. In other words, Typ-Ken is an expression for informational reality (LoA and model with ontological commitment) that can reveal seamless local and global interactions in the functioning of a flock or infosphere.

The generation of complex organ structures such as the eye requires the intricate orchestration of multiple cellular interactions. In this paper, early retinal development is discussed with respect to the structure formation of the optic cup. Although recent studies have elucidated molecular mechanisms of retinal differentiation, little is known about how the unique shape of the optic cup is determined. A recent report has demonstrated that optic‐cup morphogenesis spontaneously occurs in three‐dimensional stem‐cell culture without external forces, indicating a latent intrinsic (...) order to generate the structure. Based on this self‐organizing phenomenon, we introduce the “relaxation‐expansion” model to mechanically interpret the tissue dynamics that enable the spontaneous invagination of the neural retina. This model involves three consecutive local rules (relaxation, apical constriction, and expansion), and its computer simulation recapitulates the optic‐cup morphogenesis in silico. (shrink)

Schedule planning is one of the most crucial issues for any airline company, because the profit of the company directly depends on the efficiency of the schedule. This paper presents a novel scheduling method which solves problems related to time scheduling, fleet assignment and maintenance routing simultaneously by Genetic Algorithms. Every schedule constraint is embeded in the fitness function, which is described as an object oriented model and works as a simulater developing itself over time, and whose solution is executable (...) without human correction. The schedular is able to solve the problems involving several hundred flights in a few hours, and the solutions are superior or equivalent to those by human experts in terms of the estimated profit.
