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.

Though there has been an array of methods to evaluate the extent of sarcoidosis, it is generally difficult to detect central nervous system involvement. Recently it has become accepted that 18F-FDG PET is more sensitive than gallium scintigraphy in finding sarcoid lesions, however its usefulness and limitations for detecting sarcoidosis in the central nervous system, especially in the spinal cord, has rarely been investigated. Two patients with pathologically confirmed sarcoidosis manifested spinal symptoms. We conducted 18F-FDG PET along with conventional imagings (...) before and after treatment. Abnormal FDG uptakes which could not be detected by gallium scintigraphy were shown in the spinal cords in both patients. These abnormal uptakes were diminished in accordance with clinical improvement after treatment. Our findings suggest that 18F-FDG PET is effective in detecting and tracking the activity of spinal sarcoidosis. (shrink)

In this study, we explored how the modality would affect the input, visuo-motor coordination, and execution in the advanced pianist's sight-reading processes, as well as relations among these three phases. Thirty-two advanced pianists with 5–54 years of piano training participated in the study. All participants sight-read three two-voice pieces in either major or minor mode while their eye movements were measured by an eye-tracking device. All pieces were 20-measure long written in 4/4 m, adapted from unfamiliar Baroque pieces. Results showed (...) that sight-readers fixated more frequently and tended to spend more time performing in a minor score than in a major score. This implies that modality of a score affects an efficiency of input and visuo-motor coordination in the advanced pianist's sight-reading. Spearman's correlation coefficients showed that errors were correlated positively with the number of fixations and the duration of performance. These results add more evidence to the notion that efficiencies in input and visuo-motor coordination are related to the accuracy in execution. (shrink)

A long tradition of research in WEIRD (Western, Educated, Industrialized, Rich, Democratic) countries has investigated how people weigh individual welfare versus group welfare in their moral judgments. Relatively less research has investigated the generalizability of results across non-WEIRD populations. In the current study, we ask participants across nine diverse cultures (Bali, Costa Rica, France, Guatemala, Japan, Madagascar, Mongolia, Serbia, and the USA) to make a series of moral judgments regarding both third-party sacrifice for group welfare and first-person sacrifice for group (...) welfare. In addition to finding some amount of cross-cultural variation on most of our questions, we also find two cross-culturally consistent judgments: (1) when indi- viduals are in equivalent situations, overall welfare should be maximized, and (2) harm to individuals should be taken into account, and some types of individual harm can trump overall group welfare. We end by discussing the specific pattern of variable and consistent features in the context of evolutionary theories of the evolution of morality. (shrink)

We examine the range of anonymity that is compatible with a Paretian social welfare relation (SWR) on infinite utility streams. Three alternative coherence properties of an SWR are considered, namely, acyclicity, quasi-transitivity, and Suzumura consistency. For each case, we show that a necessary and sufficient condition for a set of permutations to be the set of permissible permutations of some Paretian SWR is given by the cyclicity of permutations and a weakening of group structure. Further, for each case of coherence (...) property, we show that the extended Pareto rule is the least element of the class of anonymous Paretian SWRs. (shrink)

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.

Gustav Radbruch, ein bekannter Rechtsphilosoph des Wertrelativismus, kam erst nach 1945 zu der Behauptung: Sowohl unerträglich ungerechte Gesetze als auch das Gleichheitsprinzip verleugnende Gesetze können keine Verbindlichkeit in Anspruch nehmen. Es ist nach wie vor umstritten, ob diese Behauptung, die später als die Radbruchsche Formel bezeichnet wurde, mit seiner wertrelativistischen Theorie vor 1945 kompatibel ist. -/- Viele Autoren verneinen diese Frage und vertreten die Umbruchthese. Einige Autoren stellen die Entwicklungsthese auf, die als eine Abschwächung der Umbruchthese verstanden werden kann. Dagegen (...) steht die Kontinuitätsthese. Auf deren Seite stellt sich die Arbeit, die den Versuch unternimmt, durch eine Verknüpfung der historischen mit der systematischen Analyse des Radbruchschen Gesamtwerkes die letzte These zu verteidigen. -/- Als Anhang enthält die Arbeit einen Zeitungsbericht über einen Vortrag von Radbruch aus dem Jahr 1923, durch den der Leser einen klaren Überblick über die Grundzüge seiner rechtsphilosophischen Auffassung gewinnen kann.

Humans can pronounce a nonword. Some researchers have interpreted this behavior as requiring a sequential mechanism by which a grapheme-phoneme correspondence rule is applied to each grapheme in turn. However, several parallel-distributed processing models in English have simulated human nonword reading accuracy without a sequential mechanism. Interestingly, the Japanese psycholinguistic literature went partly in the same direction, but it has since concluded that a sequential parsing mechanism is required to reproduce human nonword reading accuracy. In this study, by manipulating the (...) list composition, we demonstrated that past psycholinguistic studies in Japanese have overestimated human nonword reading accuracy. When the more fairly reevaluated human performance was targeted, a newly implemented Japanese PDP model simulated the target accuracy as well as the error patterns. These findings suggest that PDP models are a more parsimonious way of explaining reading across various languages. (shrink)

A growing body of literature critical of ethics review boards has drawn attention to the processes used to determine the ethical merit of research. Citing criticism on the bureaucratic nature of ethics review processes, this literature provides a useful provocation for (re)considering how the ethics review might be enacted. Much of this criticism focuses on how ethics review boards _deliberate,_ with particular attention given to the lack of transparency and opportunities for researcher recourse that characterise ethics review processes. Centered specifically (...) on the conduct of ethics review boards convened within university settings, this paper draws on these inherent criticisms to consider the ways that ethics review boards might enact more communicative and deliberative practices. Outlining a set of principles against which ethics review boards might establish strategies for engaging with researchers and research communities, this paper draws attention to how _Deliberative communication_, _Engagement with researchers_ and the _Distribution of responsibility_ for the ethics review might be enacted in the day-to-day practice of the university human ethics review board. This paper develops these themes via a conceptual lens derived from Habermas’ (The theory of communicative action. Volume 1: Reason and the rationalization of society, 1984 ) articulation of ‘communicative action’ and Fraser’s (Social Text, 25(26), 56–80, 1990 ) consideration of ‘strong publics’ to cast consideration of the role that human ethics review boards might play in supporting university research cultures. _Deliberative communication_, _Engagement with researchers_ and the _Distribution of responsibility_ provide useful conceptual prompts for considering how ethics review boards might undertake their work.

BackgroundBoth impairment and sex differences in social cognition and neurocognition have been documented in schizophrenia. However, whether sex differences exist in the association between social cognition and neurocognition are not known. We aimed to investigate the contribution of areas of neurocognition to theory of mind and hostility bias, representing social cognition, according to sex in early course schizophrenia.MethodsIn this cross-sectional study, we assessed neurocognition using the Japanese version of the Brief Assessment of Cognition in Schizophrenia and assessed the ToM and (...) hostility bias subdomains of social cognition using the Social Cognition Screening Questionnaire in 131 participants diagnosed with schizophrenia within 5 years of onset. Sex differences were analyzed using t-tests. The associations of neurocognitive subdomains with ToM and hostility bias according to sex were analyzed using multiple regression analysis. Results were adjusted by age, estimated premorbid intelligence quotient, and symptomatology.ResultsNo sex differences were found in ToM or hostility bias. Higher verbal fluency was significantly associated with higher ToM in females, whereas higher executive function was significantly associated with higher ToM in males. Higher verbal fluency was significantly associated with lower hostility bias in females, whereas neurocognition and hostility bias were not significantly associated in males.ConclusionThe results suggest that neurocognition associated with social cognition differ according to sex. These differences should be considered for more effective treatment of social cognition. (shrink)

The idea of taiji 太極 as the supreme ultimate of the universe has been largely avoided by Chinese philosophers over the past several hundred years, and the same is true of the notions of yin 陰, yang 陽, and qi 氣. The main objection seems to be that these notions operate in a way inconsistent with modern science, but the present essay argues that when we view yin and yang as complements rather than opposites, they can be applied consistently (...) with modern science and in a way that takes in both mental and physical instances. This can lead us to recognize the similarity between the mental and the physical along lines that permit us to revive the notion of qi and treat it as not only in keeping with modern ideas but as also allowing a new kind of validity to the ancient notion of taiji. The West has a lot to learn from a proper modernized account of these concepts, but these are lessons that Westernizing Chinese thinkers also need to learn. (shrink)

The present article illustrates the well-known affinity between Whitehead’s process philosophy and Chinese thought by mapping the category of the ultimate and the categories of existence in Whitehead’s categoreal scheme onto the Taiji and Bagua diagrams as developed in The Book of Changes, or I Ching. The Taiji-Bagua diagrams are models of organic unity that provide a framework and structure to better understand the category of the ultimate and the categories of existence—particularly how these categories are related to (...) each other. They illustrate more clearly the coherent nature of Whitehead’s speculative philosophy as stated in Process and Reality. (shrink)

The article is devoted to the analysis of the influence of the ancient Chinese philosophy of Taiji on artistic creativity and the development of the internal evolution of artistic culture. Taoist philosophy of nature and Confucian ethics synthesized the philosophical core of the traditional Chinese worldview with its emphasis on the simplicity and naturalness of the world order, and formed the fundamental principles of Taiji. Fundamental to Taiji, the concept of Yin and Yang emphasizes the dual nature (...) of the existence of movement and variability as a balance of opposing forces of development. The Taiji philosophy of dialectical development is supplemented by the idea of ​​the genesis of renewal energy - Qi. The main research method is the method of revitalizing traditional systems on a new intellectual basis. The method of diachronic analysis of the social situation that influenced the development of Chinese neorealism in art was used. As a result of the study, the functional significance of the influence of the principles and philosophical ideas of taiji on the evolution of neorealism is described. Using the example of the work of Chinese neorealist artists Xin Dongwan and Zheng Yi, the authors come to the conclusion that there are three driving factors of artistic motivation for creativity: internal, external and subjective. The basic principles of Taiji philosophy and ethics, such as: the naturalness of change without the use of force (Wu Wei), change as the only constant in the existence of the world and its stability, gentleness - help develop the creative power of renewal. The idea is shown that in the ancient Chinese philosophical heritage, Confucianism and Taoism became two full-fledged directions, functionally complementing each other in explaining differences in cultural, political, philosophical and social environments.

Jesuits in China adopted key Confucian terms to express Christian notions; for example, Tian 天 or Shangdi 上帝 was considered an equivalent for God, and guishen 鬼神 for angels. A Terms controversy started among the Jesuits and other missionaries and developed into the famous Rites Controversy. However, all the missionaries agreed in rejecting the Neo-Confucian concept of Taiji 太極, which was believed to be materialistic, pantheistic, or atheistic. The Flemish Jesuit François Noël, after a careful study of Neo-Confucian texts, (...) interpreted Taiji with the Western concept of nature, and even claimed that it held theistic meaning. We shall analyze and evaluate here this early Western attempt in giving a positive meaning to Taiji. (shrink)

Taiji – sport, meditation, martial art , health preservation, way of enlightenment and philosophy of life – is one the best-known signs for recognizing Chinese Daoism. The following article wishes to explain the influence of classical philosophical Taoism notions such as dao , qi and wuwei and their application on Taiji principles practiced today world wide. Arising from tradition of an early Daoism those notions are the core of its fundamental books and forming material of Daoistic philosophy, which (...) has managed, despite its exposure to great historical changes and religious influences during the thousands of years, to preserve its autonomy owing to the application of those axioms. Regularly practicing Taiji with the aim of mens sana in corpore sano and appreciating the rules of principles dao, qi and wuwei directly result in suppleness, strength and composure of body and spirit and carries us to higher levels of consciousness in which we are able to achieve the unity of physical and mental perfection. In this manner Taiji as ”sport” gains its complete, transcendent dimension. (shrink)

Taiji – sport, méditation, art martial , préservation de la santé, philosophie de vie et voie de l’illumination – est l’une des caractéristiques du daoïsme chinois les plus connues. Cet article cherche à saisir la portée des notions daoïstes classiques, telles que dao , qi et wuwei , ainsi que leur mise en application dans les principes de Taiji tel que pratiqué aujourd’hui à travers le monde entier. Issues de la première génération du daoïsme , ces notions représentent (...) le point central de ses écrits fondateurs et constituent les bases de la philosophie daoïste qui a réussi à préserver son authenticité, malgré de nombreuses évolutions historiques et influences religieuses pendant mille ans, justement grâce à l’application de ces axiomes. Une pratique régulière de Taiji, avec pour but mens sana in corpore sano, et le respect des principes de dao, qi et wuwei, conduisent à la souplesse, la force et la pondération de l’esprit et du corps, puis mènent vers des niveaux de conscience plus élevés où il est possible d’atteindre l’unité de la perfection physique et mentale. C’est ainsi que le « sport » Taiji revêt sa dimension intégrale et transcendante. (shrink)

Taiji – Sport, Meditation, Kampfkunst , Gesundheitserhaltung, Lebensphilosophie und der Weg zur Erleuchtung – ist eines der bekanntesten „Markenzeichen” des chinesischen Daoismus. Der folgende Artikel stellt die Grundbegriffe des philosophischen Daoismus, wie dao , qi und wuwei vor, und verbindet sie mit den Prinzipien des Taiji. Entstanden in der Tradition des philosophischen Daoismus stehen diese Begriffe im Zentrum von Schriften wie Daodejing und Zhuangzi, und dienen als Bausteine der daoistischen Philosophie, die sich gerade durch die Beständigkeit dieser Axiome (...) während einer tausendjährigen Geschichte sozialer, politischer und religiöser Umwälzungen als stabil erwiesen hat. Aus dem regelmäßigen Taiji-Training mit dem Ziel mens sana in corpore sano und unter Beachtung der Prinzipien des dao, qi und wuwei resultieren Weichheit und Stärke des Körpers und Weisheit des Geistes, wodurch sich höhere Ebenen des Bewusstseins eröffnen, in denen es möglich wird, eine Einheit physischer und mentaler Vollkommenheit zu erlangen. Dadurch gewinnt die „Kampfkunst” Taiji eine weitere, transzendente Dimension. (shrink)

This article suggests that reading Zhou Dunyi’s 周敦頤 Explanation to the Diagram of Supreme Polarity synchronously instead of diachronically yields a new understanding on the relatedness between infinitude and finitude, or on the One and many. Zhou’s attitude is introduced as a living riddle, in which “Non-Polar and Supreme Polarity” is understood as a new conceptual construct, and one which is issued as a call for action at the end of the text: it is a call to investigate the beginnings (...) and endings of one’s life. In this way, the text demonstrates how a person embodies the cosmological as riddle. The article follows both the diagram and text. It first refers to the riddle, then moves on to its embodiment in the ongoing processes of living as yin-yang 陰陽, the five phases, qian 乾 and kun 坤, and the myriad things, including human beings. According to the approach presented here, it is the sage who is the human embodiment of “Non-Polar and Supreme Polarity.”. (shrink)

In this article, the author examines the work of the Neo-Confucian thinker Zhou Dunyi , particularly his seminal essay, "Explanation of the Diagram of the Great Ultimate" , as a key articulation of the anthropocosmic vision that underlies the traditional Chinese practice of taijiquan. Although often associated with Daoism, the art of taiji actually draws on cosmological principles widely shared by followers of all Chinese schools of thought. Through a careful reading of Zhou's essay, it becomes apparent that Zhou (...) is deeply versed in this very ancient pan-Chinese cosmic vision, giving his essay a decidedly mystical air. However, Zhou also takes pains to give his essay a distinctive Confucian flavor by stressing the necessity of human moral action in establishing proper cosmic balance. This marriage of the more mystical and practical/ moral suggests that Zhou himself may have been a practitioner of some form of taijiquan, as that are functions by combining both aspects of Chinese philosophy. Whether this suggestion is true or not, however, Zhou's "Explanation" stands as perhaps the best articulation of the "essence" of taiji found in traditional sources. (shrink)
