Green consumers are those who seek to fulfill economic responsibility with their choices of environment-friendly products. Previous research found that it is not easy to identify green consumers by using traditional demographic or psychographic measurements due to the instability of moral attitude and actual behavior. The frontal theta brain waves of 19 right-handed respondents were recorded and analyzed in a choice task between an environment-friendly (green) product and a conventional product. Product information, which was provided to the respondents, included written (...) descriptions as well as the price of each product without visual depiction. Based on the respondents’ choice, they were classified into two groups: green (GR) consumers who chose an environment-friendly product option and non-green (Non-GR) consumers who chose the option of a conventional product. While processing the green product message, we discovered that frontal theta activations were significantly higher among GR consumers than Non-GR consumers. On the contrary, the frontal theta waves of GR consumers were not differentiated from Non-GR consumers while processing the price information. Therefore, theta activations in the frontal area may potentially be a unique neural indicator of GR consumers’ cognitive engagement with environment-friendly product messages. (shrink)

While social interaction and play in a VR environment are becoming ever more popular, little is known about how social VR games affect users. The purpose of this study was to elucidate the role of several contingent factors in social VR games by modeling the relationships between involvement, well-being, depression, self-esteem, and social connectedness. A conditional process-moderated mediation model of the measured variables was analyzed with 220 pieces of collected data. The result showed that: the direct effect of involvement on (...) well-being was significant, and the index of moderated mediation involving depression, self-esteem, and social connectedness was significant. We conclude that high levels of involvement in social VR games by socially isolated users with low self-esteem can negatively affect their well-being. The findings of this study contribute in several ways to our understanding of the effect of social VR games upon users and provide important practical implications. (shrink)

This study investigates the characteristics of the generalized gravitation equation in a complex spacetime manifold. The newly applied complex spacetime coordinates were designed to integrate peculiar velocity and the receding velocity of the particle into a single coordinate system. On this basis, the Schwarzschild metric solution was extended to a complexified version, and a generalized geodesic equation was derived in the complex spacetime manifold. It was found from the derived gravitation equation that the gravitation interaction depends on the space deceleration (...) parameter \ and can act as a repulsive force in the giant space scale that satisfies \. These results require a rapid expansion of space in the early universe and suggest that the gravitational interactions of matter are fundamentally linked to the space expansion characteristics.

The importance of the notion of common knowledge in sustaining cooperative outcomes in strategic situations is well appreciated. However, the systematic analysis of the extent to which small departures from common knowledge affect equilibrium in games has only recently been attempted.We review the main themes in this literature, in particular, the notion of common p-belief. We outline both the analytical issues raised, and the potential applicability of such ideas to game theory, computer science and the philosophy of language.

How can sport community involvement influence life satisfaction during a pandemic? Self-expansion theory posits that individuals seek to gain resources such as positive interpersonal relationships for growth and achievement. By considering psychological capital as a dispositional resource intervening between sport community involvement and life satisfaction, we examined an empirical model to test the chain of effects. Based on the stress process model, distress and generational group were tested as moderators. Participants responded to the scale item questionnaire for model assessment. Supporting (...) the hypothesized relationships, the model was supported with a significant moderated-moderated mediation. The mediation effect of PsyCap was stronger when distress level was lower and such interaction effect was amplified for Generation Z. Whereas the global sport communities and Gen Z were found to be more particularly vulnerable to COVID-19, our findings suggest that there are psychological pathways for fans to maintain their resilience. It is foremost imperative to lower the stress level of sport fans for their community involvement to positively affect life satisfaction. Gen Z were more stressed during the pandemic but individuals who managed to cope with stress were able to leverage community involvement to boost positive psychological resources. Acknowledgment of these effects brings implications for better management strategies and provides avenues for new research. (shrink)

In the 1990s, large insurance companies failed in virtually every major market, prompting a fierce and ongoing debate about how to better protect policyholders. Drawing lessons from the failures of four insurance companies, When Insurers Go Bust dramatically advances this debate by arguing that the current approach to insurance regulation should be replaced with mechanisms that replicate the governance of non-financial firms.Rather than immediately addressing the minutiae of supervision, Guillaume Plantin and Jean-Charles Rochet first identify a fundamental economic rationale for (...) supervising the solvency of insurance companies: policyholders are the "bankers" of insurance companies. But because policyholders are too dispersed to effectively monitor insurers, it might be efficient to delegate monitoring to an institution--a prudential authority. Applying recent developments in corporate finance theory and the economic theory of organizations, the authors describe in practical terms how such authorities could be created and given the incentives to behave exactly like bankers behave toward borrowers, as "tough" claimholders.

BackgroundAlthough the Life-Sustaining Treatment (LST) Decision Act was enforced in 2018 in Korea, data on whether it is well established in actual clinical settings are limited. Hospital-acquired pneumonia (HAP) is a common nosocomial infection with high mortality. However, there are limited data on the end-of-life (EOL) decision of patients with HAP. Therefore, we aimed to examine clinical characteristics and outcomes according to the EOL decision for patients with HAP.MethodsThis multicenter study enrolled patients with HAP at 16 referral hospitals retrospectively from (...) January to December 2019. EOL decisions included do-not-resuscitate (DNR), withholding of LST, and withdrawal of LST. Descriptive and Kaplan–Meier curve analyses for survival were performed.ResultsOf 1,131 patients with HAP, 283 deceased patients with EOL decisions (105 cases of DNR, 108 cases of withholding of LST, and 70 cases of withdrawal of LST) were analyzed. The median age was 74 (IQR 63–81) years. The prevalence of solid malignant tumors was high (32.4% vs. 46.3% vs. 54.3%, P = 0.011), and the ICU admission rate was lower (42.9% vs. 35.2% vs. 24.3%, P = 0.042) in the withdrawal group. The prevalence of multidrug-resistant pathogens, impaired consciousness, and cough was significantly lower in the withdrawal group. Kaplan–Meier curve analysis revealed that 30-day and 60-day survival rates were higher in the withdrawal group than in the DNR and withholding groups (log-rank P = 0.021 and 0.018). The survival of the withdrawal group was markedly decreased after 40 days; thus, the withdrawal decision was made around this time. Among patients aged below 80 years, the rates of EOL decisions were not different (P = 0.430); however, mong patients aged over 80 years, the rate of withdrawal was significantly lower than that of DNR and withholding (P = 0.001).ConclusionsAfter the LST Decision Act was enforced in Korea, a DNR order was still common in EOL decisions. Baseline characteristics and outcomes were similar between the DNR and withholding groups; however, differences were observed in the withdrawal group. Withdrawal decisions seemed to be made at the late stage of dying. Therefore, advance care planning for patients with HAP is needed. (shrink)

This study assessed the knowledge and perception of human biological materials (HBM) and biorepositories among three study groups in South Korea. The relationship between the knowledge and the perception among different groups was also examined by using factor and regression analyses. In a self-reporting survey of 440 respondents, the expert group was found more likely to be knowledgeable and positively perceived than the others. Four factors emerged: Sale and Consent, Flexible Use, Self-Confidence, and Korean Bioethics and Biosafety Action restriction perception. (...) The results indicate that those who are well aware of the existence of biobanks were more positively inclined to receive the Sale and Consent perception. As a result of the need for high quality HBMs and the use of appropriate sampling procedures for every aspect of the collection and use process, the biorepository community should pay attention to ethical, legal, and policy issues.

Smartphone app-use patterns will predict professional golfers’ athletic performance, and the use time of serious apps would be associated with improved performance. This longitudinal 4-week observation of 79 professional golfers assessed golf handicaps and smartphone app-use patterns at the start of the Korean professional golf season and 2 and 4 weeks later. We classified use as social networking, entertainment, serious apps, and others. Use time of entertainment apps increased for non-improved golfers but did not change for improved golfers. Use time (...) of serious apps increased for improved golfers and decreased for non-improved ones. Changes in golf handicaps were positively correlated with changes in entertainment app use time and negatively correlated with changes in serious app use time. Professional golfers’ sports performance was not associated with smartphone use time but was with the smartphone app type. The management of smartphone app-use patterns is important for professional golfers’ performance. (shrink)

L’acte de la philosophie japonaise est celui d’un évidement de soi: acte d’accueil des traditions philosophiques du monde, acte en résonance, créateur d’une terminologie, d’une logique, d’une conceptualité originales, s’alimentant aux sources d’une pensée mythique jamais tarie. Les textes présentés ici en feront sentir l’inclassable nouveauté: cette philosophie n’est ni purement shintoïste, bouddhique, chrétienne, néoconfucianiste ; elle n’est ni « orientale » ni « occidentale », mais proprement japonaise.

In the current performance evaluation works of commercial banks, most of the researches only focus on the relationship between a single characteristic and performance and lack a comprehensive analysis of characteristics. On the other hand, they mainly focus on causal inference and lack systematic quantitative conclusions from the perspective of prediction. This paper is the first to comprehensively investigate the predictability of multidimensional features on commercial bank performance using boosting regression tree. The dimensionality in the financial-related fields is relatively high. (...) There are not only observable price data, financial fundamentals data, etc., but also many unobservable undisclosed data and undisclosed events; more sources of income cannot be explained by existing models. Aiming at the characteristics of commercial bank data, this paper proposes an adaptively reduced step size gradient boosting regression tree algorithm for bank performance evaluation. In this method, a random subsample sampling is performed before training each regression tree. The adaptive reduction step size is used to replace the reduction step size setting of the original algorithm, which overcomes the shortcomings of low accuracy and poor generalization ability of the existing regression decision tree model. Compared to the BIRCH algorithm for classification of existing data, our proposed gradient boosting regression tree algorithm with adaptively reduced step size obtains better classification results. This paper empirically uses data from rural banks in 30 provinces in China to classify the different characteristics of rural banks’ performance in order to better evaluate their performance.

The two mythical tales from the Samguk yusa, “Lady Suro” and “Monk Hyet’ong Defeats the Dragon” reveal the little-known evil character of the Korean dragons. The second story presents a particular scene of a confrontation between a hero and a malicious dragon; this story leads us to reflect on the question of the symbolism of evil embodied by the Dragon who has a vengeful character. The dragon symbol and its semantic variations were constructed specifically within the singular Korean context and (...) cannot be limited to Chinese Buddhist heritage. (shrink)

In this engaging book, Kosman offers a vigorous extended defence of a distinctive and highly ambitious claim, namely, that Aristotle’s account of potentiality/ability and actuality/activity in book Theta of the Metaphysics is an integral and central part of Aristotle’s account of what being is, which means that, for Kosman, Aristotle defends the thesis that being is, precisely, activity. In addition to the distinctive character of this claim, there are two notable suppositions behind it, which, likewise, Kosman defends. First, the Metaphysics (...) is addressed to a single, overall question, namely ‘What is it for something to be?’, a question that Aristotle introduces in book Gamma, takes on in books Zeta and Eta, gives a distinctive answer to in Theta and takes to its point of culmination in Lambda. This question, as Kosman spells out instructively and at length, is tackled by Aristotle through a distinction between primary being, or substance , and other beings .. (shrink)
