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.

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.

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)

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.

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)

This essay takes as its focus Japanese philosopher Nishida Kitar? (1870?1945) and his seminal first text, An Inquiry into the Good (or in Japanese zen no kenky?). Until now scholarship has taken for granted the predominantly Buddhist orientation of this text, centered around an analysis of the central concept of ?pure experience? (junsui keiken) as something Nishdia extrapolates from his early experience of Zen meditation. However, in this paper I will present an alternative and more accurate account of the origins (...) of this important work, a text often seen as marking the beginning of Modern Japanese philosophy. I will show that while Buddhism is an important part of Nishida's early intellectual development, there is ample biographical and textual evidence to suggest that zen no kenky? is at its core a text which attempts to solve key ethical problems via a modern interpretation of concepts drawn from the Confucian tradition. This analysis thus places the concept of ?Conduct? (koi), rather than ?pure experience?, at the center of the text, suggesting that ethics, rather than metaphysics, is the core theme of the book.

Previous studies have found that serum lipid levels independently associate with mental health problems in adulthood. However, little is known about the association between serum lipid levels and positive aspects of mental health such as resilience and self-esteem, which develop in adolescence. The aim of this study is to examine the association between serum lipid levels and resilience and self-esteem in Japanese adolescents. Data were pooled data from the Adachi Child Health Impact of Living Difficulty study in 2016 and (...) 2018, a school-based, cross-sectional study in Adachi City, Tokyo, Japan. Resilience of the child was assessed by caregivers, and self-esteem was self-identified via questionnaires. Serum lipid levels [total cholesterol, low-density lipoproteins, and high-density lipoproteins ] were assessed in school health checkup, in addition to height and weight measurements. Multiple linear regression was applied to investigate the association between standardized serum lipid levels and resilience and self-esteem. LDL showed inverse association with resilience [β = −1.26, 95% confidence interval = −2.39 to −0.14] after adjusting for child’s BMI, month of birth, sex, absence of parent, household income, caregiver’s mental health, and lifestyle. We also found an inverse association of total cholesterol and higher LDL cholesterol with self-esteem. HDL cholesterol was not associated with resilience and self-esteem. Among Japanese adolescent, total and LDL cholesterol may be biomarkers of resilience and self-esteem. (shrink)

Gustav Radbruch war Deutschlands beruhmtester Rechtsphilosoph im 20. Jahrhundert. Seine gehaltvollen, aber auch spannungsreichen Schriften pragen die deutschsprachige Rechtsphilosophie bis heute. Im Zentrum von Radbruchs Lehre steht sein neukantianisch gepragter Rechtsbegriff, der im Laufe der Zeit eine Reihe von Veranderungen erfahren hat. Die Beitrage in diesem Band sind Radbruchs Rechtsbegriff im Allgemeinen und den Wandlungen dieses Rechtsbregriffs im Besonderen gewidmet. Nach der orthodoxen Lesart vertrat Radbruch vor dem Kriege eine rechtspositivistische Lehre, wurde unter dem Eindruck der nationalsozialistischen Grauel jedoch zum (...) Naturrecht bekehrt. Zunehmend wird gesehen, dass diese 'Bekehrungsthese' zu Ungereimtheiten fuhrt. Verschiedene Beitrage dieses Bandes betonen demgegenuber die Kontinuitat nichtpositivistischer Elemente in der Entwicklung von Radbruchs Rechtsbegriff.

Psychiatry and Religious Studies have common interests in extreme and extraordinary states when articulated in the languages of religions. For Religious Studies the problems with the category of religious experience are philosophical and profound; whilst the resurgence of interest in religion by psychiatrists (three meta-analyses in the past five years) has not repaired the damaging legacy of reductionist interpretations. In this paper I adopt an interdisciplinary approach to the religious experience discourse. From psychiatry I apply the new idea of Disruption, (...) which makes its first appearance in the US psychiatric textbook DSM-5 (APA, 2013); and the older Biopsychosocial model (Engel, 1977). From Physiology I apply the language of ‘ictal’ (Adachi, 2002, 2010) to privilege a dynamic idea of time. These concepts involve particular epistemological presuppositions and, as this is an interdisciplinary, rather than a multidisciplinary contribution, these will be critically developed. The approach I propose provides a way of holistically addressing the categories of Mysticism, Possession and Altered States of Consciousness, as acute or extreme categories of experience. I propose that the idea of ‘Disruption’ can act as a pre-interpretive placeholder for a real existential experience which might (or might not) result in a non-pathological diagnosis of religious experience. The outcome depends on the socialisation of interpretation. I hope to show that the idea that there might be alternative interpretations removes the need for a sui generis defence of religious experience. By insisting on a biopsychosocial approach within an ictal framework, a way beyond the linguistic impasse of interpretation is proposed; the essentialism, implicit in the mysticism discourse, is questioned; and the non-medicalisation of Possession confirmed. The limitations of this paper point to the opportunity for further conversations between interested parties, including people with experiences of Disruption. (shrink)

Child poverty leads to various negative consequences, including low self-esteem, which is a risk factor for mental illness, suicide, or poor academic achievement. However, little is known about why child poverty leads to low self-esteem. We aimed to elucidate the association of child poverty and low self-esteem based on the ecological model, which includes family-level, school-level, and community-level factors. Data were obtained from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study in 2016, and participants included 1,652 children (...) in fourth grade (534 pairs), sixth grade (530 pairs), and eighth grade (588 pairs) living in Adachi City, Tokyo. A questionnaire survey was implemented to assess child poverty, parental mental health, parental involvement with children, parental social capital by caregivers, and self-esteem and school social capital by children. The structural equation model was applied to elucidate the association between child poverty and low self-esteem, using family-level (parental mental health and parental involvement with children), school-level (school social capital), and community-level (parental social capital) factors. Child poverty was associated with low self-esteem. Child poverty leads to poor parental involvement, which can be indirectly associated with poor parental mental health and poor parental social capital, and poor parental involvement was directly or indirectly associated with low self-esteem through poor school social capital. To mitigate the impact of child poverty on low self-esteem, comprehensive health policies targeting family-level (parental mental health and parental involvement with children), school-level (school social capital), and community-level (parental social capital) factors may be effective.

In de?Hal van de acht wijzen? in de Sankeientuin (Yokohama, Japan) staan de standbeelden van grote leraren van de mensheid: Boeddha, Confucius, Jezus en enkele Zenleraren. Onder hen is ook het beeld van Socrates. Voor Kenzo Adachi, die de hal bouwde, was Socrates vooral een spirituele leider, een levensgids, een voorbeeld van deugd, wijsheid en geluk.0Bij welke filosofische traditie je ook te rade gaat, overal kom je Socrates tegen. Sommigen noemen hem de vader van de filosofie, anderen zien hem (...) als een leermeester in correct denken of morele moed. Zoveel tradities, zoveel Socratessen. En, opmerkelijk: al die Socratessen zijn nog geloofwaardig ook.0Rico Sneller presenteert een geschiedenis van de filosofie aan de hand van alle Socratessen die de filosofische traditie rijk is.Na Xenofons en Aristofanes? Socrates gaat hij onder meer in op de Socrates van Hegel, Kierkegaard, Nietzsche, Strauss en Derrida.0We zijn nog lang niet uitgepraat over Socrates.
