朱熹の思想は「朱子学」となって東アジアに影響を与えてきた。その学の基本的枠組みである修養論を実効性に留意しつつ再検討。.

In recent times, international comparative studies on managers’ beliefs regarding ethical/unethical leadership have increased in number. These studies focus on both Eastern and Western countries. However, although these previous studies focused on the effects of national culture, they did not pay sufficient attention to the effects of institutions. Moreover, these studies covered only a few countries. Despite Japan’s strong influence on the world economy, it has not been included in previous studies on ethical leadership. Thus, to reveal unexplored factors—particularly cultural (...) and institutional factors—and to determine the generalizability of previous findings, this study used a qualitative research method to examine Japanese business managers’ beliefs about ethical/unethical leadership. The data revealed the convergence and divergence in beliefs regarding ethical/unethical leadership between managers in Japan and in other countries. The analysis identified mostly the same themes of ethical/unethical leadership as found in other countries albeit with different distributions. In addition, We identified new themes that may be specific to Japan or that were neglected in previous studies. Moreover, this study suggests the necessity of considering each society’s history of business ethics and current ethics-related institutional contexts in ethical/unethical leadership studies.

Understanding consciousness is a truly multidisciplinary project, attracting intense interest from researchers and theorists from diverse backgrounds. Thus, we now have computational scientists, neuroscientists, and philosophers all engaged in the same effort. This book draws together the work of leading researchers around the world, providing insights from these three general perspectives. The work is highlighted by a rare look at work being conducted by Japanese researchers.

The Covid-19 pandemic has affected not only the health of populations but also their everyday social practices, transformed by orienting to risks of contagion and to health prevention discourses. This paper emanates from a project investigating the impact of Covid-19 on human sociality and more particularly the situated and embodied organization of social interactions. It discusses how Covid-19 impacts the design of ordinary actions in social interaction, how this is made publicly accountable by the participants orienting to the pandemic in (...) formatting their actions and in responding to the actions of others. Adopting an ethnomethodological and conversation analytic perspective, the analyses focus on a particular social activity: paying. The organization of payments in shops and services has been affected by the pandemic, not only by official regulations, favoring some modes of payment over others, but also in how sellers and customers situatedly adapt their practices to imperatives of prevention. On the basis of a rich corpus of video-recorded data, which spans from the pandemic’s prodromes to and after its peak, we show how money transfer is methodically achieved – imposed, negotiated, and readjusted – while variously taking into account possible risks of contagion. Thus, we show not only how pandemics affect social interaction, and how prevention is incarnated in social actions, but also how, in turn, situated solutions implemented by people during the pandemic reveal fundamental features of human action.

Social presence, or the subjective experience of being present with another existing person, varies with the interaction medium. In general, social presence research has mainly focused on uni-directional aspects of each exchanged message, not on bidirectional interactions. Our primary purpose is to introduce such bidirectional evaluation by quantifying the degree of social presence with a few statistical measures. To this end, we developed a software called “TypeTrace” that records all keystrokes of online chat interactants and reenacts their typing actions and (...) analyzed the results from different chat conditions, mainly focusing on the characterization of bi-directional interactions. We also compared the chat interaction patterns with the patterns from phone call datasets to investigate the difference of live communication in different media. The hypothesis of the experiment was that either richness or concurrency of communication is important for organizing social presence. Richness is defined by the variety of information at a time in communication and the concurrency is the number of temporal thread being processed at the same time. Our results show that when we merely increase the richness of information by presenting the typing process, the cognition of others' presence does not significantly increase. However, when the information concurrency is augmented by introducing the transmission of realtime text, we found that the transfer entropy between the interactants becomes considerably higher, and the social presence and emotional arousal, intimacy increased. High transfer entropy was also observed in the phone call dataset. This result shows that the mere augmentation of information richness does not necessarily lead to increased social presence, and concurrent communication is another critical factor for fostering vivid conversation in digital environments.

The Miyashita experiments are very interesting and the results should be examined from a viewpoint of attractor dynamics. Amit's target article shows a path toward realistic modeling by artificial neural networks (ANN), but it is not necessarily the only one. I introduce another model that can explain a substantial part of the empirical observations and makes an interesting prediction. This model consists of such units that have nonmonotonic input-output characteristics with local inhibition neurons.

Interpreting the Miyashita et al. experiments in terms of a cellassembly representation does not adequately explain the performance of Miyashita's monkeys on novel stimuli. We will argue that the latter observations point to acompositionalrepresentation and suggest a dynamics involving rapid and reversible binding of distinct activity patterns.

The neurophysiological evidence from the Miyashita group's experiments on monkeys as well as cognitive experience common to us all suggests that local neuronal spike rate distributions might persist in the absence of their eliciting stimulus. In Hebb's cell-assembly theory, learning dynamics stabilize such self-maintaining reverberations. Quasi-quantitive modeling of the experimental data on internal representations in association-cortex modules identifies the reverberations (delay spike activity) as the internal code (representation). This leads to cognitive and neurophysiological predictions, many following directly from the (...) language used to describe the activity in the experimental delay period, others from the details of how the model captures the properties of the internal representations.

Further tests of Amit's model are indicated. One strategy is to use the apparent coding sparseness of the model to make predictions about coding sparseness in Miyashita's network. A second approach is to use memory overload to induce false positive responses in modules and biological systems. In closing, the importance of temporal coding and timing requirements in developing biologically plausible attractor networks is mentioned.
