The Drosophila compound eye is an excellent experimental system for analysing fate induction of identifiable single cells. Each ommatidium, a unit eye, contains eight photoreceptors (R1‐R8), and the differentiation of these photoreceptors occurs in the larval eye imaginal disc in discrete steps: first R8 is determined, then R2/R5, R3/R4, R1/R6 and finally R7. Induction of R7, in particular, has been extensively studied at the molecular level. The R8 photoreceptor presents on its surface a ligand, Bride of Sevenless, that binds and (...) activates Sevenless receptor tyrosine kinase in the R7 precursor. Autophosphorylated Sevenless initiates a Ras1‐mediated cascade, which eventually activates transcription factors in the nucleus via Raf1 and MAP kinases, resulting in R7 development. However, recent studies indicate that Sevenless (Sev) functions just to neuralize the cell and has no role in R7 fate determination per se. It appears that the R7 fate may represent the lowest rung of a ‘neuronal ground state’, which is attained without any specific inductive cue. It is plausible that the R7 precursor is actively prevented from taking on the neuronal fate and this inhibition is removed by activation of Sev. (shrink)

Motor learning is the process of updating motor commands in response to a trajectory error induced by a perturbation to the body or vision. The brain has a great capability to accelerate learning by increasing the sensitivity of the memory update to the perceived trajectory errors. Conventional theory suggests that the statistics of perturbations or the statistics of the experienced errors induced by the external perturbations determine the learning speeds. However, the potential effect of another type of error perception, a (...) self-generated error as a result of motor command updates, on the learning speeds has not been examined yet. In this study, we dissociated the two kinds of errors by controlling the perception of the aftereffect using a channel-force environment. One group experienced errors due to the aftereffect of the learning process, while the other did not. We found that the participants who perceived the aftereffect of the memory updates exhibited a significant decrease in error-sensitivity, whereas the participants who did not perceive the aftereffect did not show an increase or decrease in error-sensitivity. This suggests that the perception of the aftereffect of learning attenuated updating the motor commands from the perceived errors. Thus, both self-generated and externally induced errors may modulate learning speeds. (shrink)

Some of the basic substructural logics are shown by Ono to have the disjunction property (DP) by using cut elimination of sequent calculi for these logics. On the other hand, this syntactic method works only for a limited number of substructural logics. Here we show that Maksimova's criterion on the DP of superintuitionistic logics can be naturally extended to one on the DP of substructural logics over FL. By using this, we show the DP for some of the substructural logics (...) for which syntactic methods don't work well. (shrink)

The definitive translation of the seminal treatise on the code of the samurai. Living and dying with bravery and honor is at the heart of Hagakure, a series of over 1,300 short texts written by eighteenth-century samurai Yamamoto Tsunetomo. These texts illuminate the classic Japanese concept of bushido (the Way of the Warrior), which dictated how samurai were expected to behave, conduct themselves, live, and die. Acclaimed translator William Scott Wilson has selected and translated here three hundred of those (...) texts to create an accessible distillation of this guide, making it one of the most thorough and astonishing windows into the captivating world of the samurai available. This edition includes an introduction that delves into the Zen concept of muga, or “death” of the ego, giving an in-depth historical and philosophical background for the more metaphorical reading of Hagakure that is based on Tsunetomo’s reference to bushido as “the Way of death.” Through this lens, which has held a morbid fascination for readers through the years, the classic takes on a fresh and nuanced appeal. This book was previously published under the title Hagakure. This book is part of the Shambhala Pocket Library series. The Shambhala Pocket Library is a collection of short, portable teachings from notable figures across religious traditions and classic texts. The covers in this series are rendered by Colorado artist Robert Spellman. The books in this collection distill the wisdom and heart of the work Shambhala Publications has published over 50 years into a compact format that is collectible, reader-friendly, and applicable to everyday life.

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.

La présente étude examine comment les intellectuels japonais tentèrent d’introduire l’utilitarisme lors du premier stade d’un processus de modernisation dans la seconde moitié du XIXe siècle. Elle décrit les efforts significatifs qu’ils consacrèrent à la traduction des œuvres ou des textes de Bentham et de Mill en créant de nombreux mots japonais nouveaux. Car, jusqu’à la fin de la société agraire quasi féodale du shogunat Tokugawa, il n’y avait quasiment pas eu de concepts équivalents pour des notions telles que l’individu, (...) la liberté, le droit, la démocratie, par exemple. La Restauration de Meiji de 1868, au premier abord, suggère par son nom une restauration de l’ancien régime ; mais en réalité c’était l’inverse, car il s’agissait d’un tournant décisif pour le Japon, dont le but était d’établir une nouvelle société industrielle moderne. La présente recherche fournit tout d’abord une liste chronologique des traductions des œuvres de Bentham et Mill réalisées au cours des deux premières décennies après la Restauration. Ensuite, elle évalue la précision et la validité du résultat de la traduction, en prenant comme exemple le premier paragraphe de l’Introduction aux Principes de la Morale et de la Législation. En troisième lieu, elle examine dans quelle mesure les intellectuels japonais de cette époque comprirent l’utilitarisme dans le processus de création des nouvelles traductions en japonais. Ce processus était issu de la tradition consistant à créer différents concepts japonais uniques, sous forme de mots composés de caractères hiéroglyphiques chinois, ancrés profondément dans l’influence culturelle du confucianisme qui domina longtemps à partir du VIe siècle. Enfin, la présente étude évalue comment les premières présentations de Bentham et Mill influencèrent la génération suivante d’intellectuels japonais. Ce résultat peut expliquer dans une certaine mesure pourquoi le Japon ne compte démographiquement que 0,8 % de chrétiens, et pourquoi la société japonaise est fondamentalement laïque et tournée vers le succès économique.

The Hagakure is one of the most influential of all Japanese texts--written nearly 300 years ago by Tsunetomo Yamamoto to summarize the very essence of the Japanese Samurai bushido ("warrior") spirit. Its influence has been felt throughout the world and yet its existence is scarcely known to many Westerners. This is the first translation to include the complete first two books of the Hagakure and the most reliable and authentic passages contained within the third book; all other English translations (...) published previously have been extremely fragmentary and incomplete. The principal pillars of Bushido are loyalty, filial piety, bravery and mercy. Yamamoto lived his life based on these principles and was willing to sacrifice his own life to bring them to ultimate fruition once his lord died. However, Shogunate law forbade Samurai retainers from taking their lives after their liege and master died, so Yamamoto became a monk instead--spending the last years of life in seclusion recording his wisdom and insights in the Hagakure for the edification and training of future Samurai warriors in the essence of bushido. Alex Bennett's completely new and highly readable translation of this essential work is the only full version of the Hagakure published to date. Its extensive footnotes fill in many cultural and historical gaps found in previous translations. This unique combination of readability and scholarship gives Bennett's translation a distinct advantage over all other English editions of this work. Reading this compendium of tales of a faithful and devoted samurai provides a unique insight into the nature of samurai service and its role in Japanese history and society until today. (shrink)

Actions shape what we see and memorize. A previous study suggested the interaction between motor and memory systems by showing that memory encoding for task-irrelevant items was enhanced when presented with motor-response cues. However, in the studies on the attentional boost effect, it has been revealed that detection of the target stimulus can lead to memory enhancement without requiring overt action. Thus, the direct link between the action and memory remains unclear. To exclude the effect of the target detection process (...) as a potential confounder, this study assessed the benefit of action for memory by separating items from the response cue in time. In our pre-registered online experiment, participants responded to visual Go cues by pressing a key or counting while ignoring No-go cues. In each trial, two task-irrelevant images were sequentially presented after the cue disappearance. After encoding the Go/No-go tasks, participants performed a surprise recognition memory test for those images. Importantly, we quantified the impact of overt execution of the action by comparing memories with and without motor response and the impact of covert motor processes by comparing memory between the motor and cognitive tasks. The results showed no memory differences between Go and No-go trials in the motor task. This means that the execution itself was not critical for memory enhancement. However, the memory performance in the motor No-go trials was higher than that in the cognitive No-go trials, only for the items presented away from the cues in time. Therefore, engaging the motor task itself could increase incidental memory for the task-irrelevant items compared to a passive viewing situation. We added empirical evidence on the online interaction between action and memory encoding. These memory advantages could be especially brought in action preparation and planning. We believe this fact may expand our present understanding of everyday memory, such as active learning. (shrink)

Despite the police preventing special fraud victimisation of older adults, both the number of cases and the amount of damage have remained high in Japan. ‘Special fraud’, in Japan, is a crime in which victims are tricked by fraudsters who through phone or postcards impersonate the victims’ relatives, employees and other associates, to dupe the victims of their cash or other valuables. The number of recognised cases of special fraud has been turned to increase in 2021. Although police or consumer (...) affairs administrations have been conducting all-encompassing enlightenment or public education for prevention, it is also necessary to reach out to those who are vulnerable to fraud. In this study, we determine the psychosocial characteristics of victims of special fraud in Japanese older adults. We analysed the age, gender, education, residential status, household satisfaction, risk perception and scam vulnerability scale of 56 older adults aged 60 years or older who had been victims of special fraud and 99 older adults aged 60 years or older who had never been victims of special fraud. The study found that the victimised older adults were more likely to be females who live alone and go out less frequently than the non-victimised older adults. The total scores of the scam vulnerability scale were higher among the elderly victims of special fraud compared to those who had never been scammed, suggesting that the psychosocial characteristics of victims of special fraud among older adults are being female, living alone, going out infrequently, having high confidence against fraud victimisation and responding quickly to phone calls and unknown visitors. Therefore, government agencies or family members should take care of older women who meet these characteristics to reduce their contact with fraudsters. (shrink)

The involvement of nitric oxide in cerebellar long-term depression is supported by the observation that nitric oxide is released by climbing fiber stimulation and by pharmacological tool usage. Two forms of long-term depression should be distinguished by their physiological relevance. [CRÉPEL et al.; LINDEN; VINCENT].

As a criterion of a good firm, a lucrative and growing business has been said to be important. Recently, however, high profitability and high growth potential are insufficient for the criteria, because social influences exerted by recent firms have been extremely significant. In this paper, high social relationship is added to the list of the criteria. Empirical corporate social performance versus corporate financial performance (CSP–CFP) relationship studies that consider social relationship are very limited in Japan, and there are no definite (...) conclusions for the studies in the world, because of scant data and the inappropriate methods, especially for supporting linear hypothesis which these studies are based on. In this paper, the CSP–CFP relationship is analyzed by an artificial neural networks model, which can deal with a non-linear relationship, using 10-year follow-up survey data. (shrink)

In this study, we discuss the psychological acceptability of an utterance strategy used by the Driving Support Agent. Previous literature regarding DSA suggests that the adoption of a small robot as a form will increase acceptability. However, the agent’s utterance has been reported as a problem faced by the user. Therefore, in this study, we designed the agent’s utterance using politeness strategy as described by Brown and Levinson’s famous sociolinguistics and pragmatics theory and analyzed its acceptability through a participant-based experiment. (...) In this experiment, we used positive and negative politeness strategies. In general, PPS is utilized to reflect the desire to be liked/recognized by others, whereas NPS is utilized to reflect the need for not wanting to be disturbed by others. Based on our results, PPS was rated high compared to NPS. Therefore, many participants highly evaluated PPS. However, there was a group of participants who appreciated NPS. There were also participants who evaluated the two strategies equally. The number of participants in these three groups was observed at 4:1:1. This result contributes as an index on the utterance design of the DSA. (shrink)
