This study examines whether the delegated monitoring of main banks effectively decreases severe agency problems. For example, this includes accounting fraud in bank-dominated corporate governance. In this context, the fraud triangle specifies the three main factors of opportunity, incentive, and rationalization. Main banks may reduce the factor of opportunity through actions such as monitoring, which plays a moderating role by reducing the potential for managerial misconduct, whereas, the incentive factor may be enhanced through the subsequent pressure that influences managers to (...) force turnover when they do not repay debts. The potential influence that the main banks have on the fraud rationalization factor may be stronger in firms that are more dependent on main-bank borrowing. This study analyzed data from publicly listed firms in Japan for the period between 2008 and 2016 to determine how main-bank relationships affected accounting fraud, thus allowing an assessment of delegated monitoring practices. Findings showed that main-bank relationships were helpful for reducing accounting fraud, suggesting its overall effectiveness in delegated monitoring. Results also showed that large audit firms did not necessarily prevent accounting fraud, which implies that main banks can employ their own monitoring as a substitute for the roles typically played by these firms. Here, the main policy implication is that main-bank relationships may strengthen business ethics in the context of bank-dominated corporate governance. In conclusion, the continued analysis of bank monitoring may benefit stakeholders while strengthening business ethics in bank-centered economies. (shrink)

Rhodopsins are one of the most studied photoreceptor protein families, and ion‐translocating rhodopsins, both pumps and channels, have recently attracted broad attention because of the development of optogenetics. Recently, a new functional class of ion‐pumping rhodopsins, an outward Na+ pump, was discovered, and following structural and functional studies enable us to compare three functionally different ion‐pumping rhodopsins: outward proton pump, inward Cl− pump, and outward Na+ pump. Here, we review the current knowledge on structure‐function relationships in these three light‐driven pumps, (...) mainly focusing on Na+ pumps. A structural and functional comparison reveals both unique and conserved features of these ion pumps, and enhances our understanding about how the structurally similar microbial rhodopsins acquired such diverse functions. We also discuss some unresolved questions and future perspectives in research of ion‐pumping rhodopsins, including optogenetics application and engineering of novel rhodopsins. (shrink)

Kyosei, a traditional Japanese concept, has been applied to a variety subjects, from biology to business. It has more recently become synonymous with the concepts of corporate responsibility, ethical decision making, stakeholder maximization, and responsible reciprocity. The purpose of this paper is to trace kyosei's modern business application back to ancient Confucian thought. The ideals associated with Confucianism were instrumental in the creation of Japanese business codes of ethics during the early part of the seventeenth century. A short history of (...) this period is presented to provide a contextual framework for understanding these codes. A specific code of ethics, called the shuchu kiyaku, is presented for the first time in English and shown to have direct roots in Confucian writings. Statements from modern company codes and from modern Japanese and American businessmen are presented to reflect the philosophy of business embodied in that ancient code of ethics. (shrink)

This article describes a number of human cohort studies based on the concept of brain‐science and education. These studies assess the potential effects of new technologies on babies, children and adolescents, and test hypotheses drawn from animal and genetic case studies to see if they apply to people. A flood of information, virtual media, individualism and the pursuit of efficiency might be transforming our brain and its functions. An environmental assessment from the metaphysical aspect could be essential to providing an (...) appropriate environment for future generations. (shrink)

—Human eyes not only serve the function of enabling us “to see” something, but also perform the vital role of allowing us “to show” our gaze for non-verbal communication, such as through establishing eye contact and joint attention. The eyes of service robots should therefore also perform both of these functions. Moreover, they should be friendly in appearance so that humans may feel comfortable with the robots. Therefore we maintain that it is important to consider gaze communication capability and friendliness (...) in designing the appearance of robot eyes. In this paper, we propose a new robot face with rear-projected eyes for changing their appearance while simultaneously realizing the showing of gaze by incorporating stereo cameras. Additionally, we examine which shape of robot eyes is most suitable for gaze reading and gives the friendliest impression, through experiments where we altered the shape and iris size of robot eyes. Keywords: Gaze reading; facial design; projector camera system. (shrink)

Transnational labour migration has recently returned to the spotlight in Japan, due to its rapidly declining population and labour force. This paper argues that the tension between the (self-)illusion of Japan as a homogeneous nation-state and trans-border labour-importing to ensure the continued supply of the workforce has inherently characterized the process of Japan’s modernity since the Meiji Restoration of 1868. In doing so, it seeks to demonstrate how the synchrony of such ostensibly conflicting interests makes eminent economic sense to recruit (...) migrant workers in order to ameliorate chronic labour shortages while keeping their labouring and living condition perpetually insecure and vulnerable.

The anchoring effect is a form of cognitive bias in which exposure to some piece of information affects its subsequent numerical estimation. Previous studies have discussed which stimuli, such as numbers or semantic priming stimuli, are most likely to induce anchoring effects. However, it has not been determined whether anchoring effects will occur when a number is presented alone or when the semantic priming stimuli have an equivalent dimension between a target and the stimuli without a number. We conducted five (...) experimental studies using stimuli to induce anchoring effects. We found that anchoring effects did not occur when a number was presented alone or when phrases to induce semantic priming were used without presenting a number. These results indicate that both numerical and semantic priming stimuli must be presented for anchoring effects to occur. Our findings represent a substantial contribution to the literature on anchoring effects by offering insights into how these effects are generated. (shrink)

A decrease in cortical excitability tends to be easily followed by an increase induced by external stimuli via a mechanism aimed at restoring it; this phenomenon is called “homeostatic plasticity.” In recent years, although intervention methods aimed at promoting motor learning using this phenomenon have been studied, an optimal intervention method has not been established. In the present study, we examined whether subsequent motor learning can be promoted further by a repetitive passive movement, which reduces the excitability of the primary (...) motor cortex before motor learning tasks. We also examined the relationship between motor learning and the brain-derived neurotrophic factor. Forty healthy subjects participated. Subjects were divided into two groups of 20 individuals each. The first group was assigned to perform the motor learning task after an intervention consisting in the passive adduction–abduction movement of the right index finger at 5 Hz for 10 min, while the second group was assigned to perform the task without the passive movement. The motor learning task consisted in the visual tracking of the right index finger. The results showed that the corticospinal excitability was transiently reduced after the passive movement in the RPM condition, whereas it was increased to the level detected in the control condition after the motor learning task. Furthermore, the motor learning ability was decreased immediately after the passive movement; however, the motor performance finally improved to the level observed in the control condition. In individuals carrying the Val/Val genotype, higher motor learning was also found to be related to the more remarkable changes in corticospinal excitability caused by the RPM condition. This study revealed that the implementation of a passive movement before a motor learning tasks did not affect M1 excitatory changes and motor learning efficiency; in contrast, in subjects carrying the Val/Val polymorphism, the more significant excitatory changes in the M1 induced by the passive movement and motor learning task led to the improvement of motor learning efficiency. Our results also suggest that homeostatic plasticity occurring in the M1 is involved in this improvement. (shrink)

Objectives: This study aimed to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) to improve subjective well-being (SWB), including evaluative, hedonic, and eudemonic well-being, and the mental component of quality of life (QOL) of working population. Methods: A literature search was conducted, using PubMed, Embase, PsycINFO, and PsycARTICLES. Eligible studies included those that were RCTs of any intervention, conducted among healthy workers, measured SWB as a primary outcome, and original articles in English. Study characteristics, intervention, outcomes, and (...) results on SWB outcomes were extracted by the investigators independently. After a brief narrative summarizing and classifying the contents of the interventions, the included outcomes were categorized into each aspect of SWB (evaluative, hedonic, and eudemonic well-being, and the mental component of QOL). Finally, the characteristics of the effective interventions for increasing each aspect were summarized, and the pooled effect of interventions on SWB was investigated by a meta-analysis. Publication bias was investigated by drawing a funnel plot and conducting Egger's test. Results: From the 5,450 articles found, 39 met the inclusion criteria for the systematic review. The interventions included in this review were classified into six categories (physical activity, ergonomics, psychological, environmental, multicomponent intervention, and others). The meta-analysis from 31 studies showed that the pooled effect of included interventions on SWB was significantly positive (standardized mean difference (SMD) = 0.51; standard error (SE) = 0.10). A funnel plot showed there were extremely large or small SMDs, and Egger's test was significant. Thus, we conducted sensitivity analysis, excluding these extreme SMDs, and confirmed that the estimated pooled effect was also significantly positive. Subgroup analyses for separate types of interventions showed the effects of psychological interventions (e.g., mindfulness, cognitive behavioral based approach, and other psychological interventions) were also significantly positive. Conclusion: The current study revealed the effectiveness of interventions for increasing SWB. Specifically, psychological interventions (e.g., mindfulness, cognitive behavioral based approach, and other psychological interventions) may be useful for improving SWB. (shrink)
