In The Self-Overcoming of Nihilism (1949), Nishitani Keiji provides a thoroughgoing questioning of the theme of nihilism in Japan. Yet, while the text contains a sharp and penetrating interpretation of Heidegger, it focuses on the early Heidegger, whose thinking had not yet ventured into the theme of nihilism. The relationship between Heidegger and Nishitani thus contains a certain “gap” that needs to be investigated. This study takes a cue from the appendix to the The Self-Overcoming of Nihilism, “Nihilism and Existence (...) in Nietzsche,” in order to clarify the differences between Heidegger and Nishitani vis-à-vis Nietzsche’s nihilism. Through this process, we will come to know the difference in their positions on who is the “subject (主体)” of nihilism in terms of their interpretations of a constellation of Nietzsche’s key terms, such as “will to power,” “the eternal return of the same,” the “overman,” “amor fati,” and so forth. From there, we will further identify some of the issues involved in their particular understandings of nihilism, and present a perspective on “contemporary nihilism.” I argue that central to their differences is the status of “morals” in nihilism.

This essay examines the political implications of Edo (present-day Tokyo) popular culture in early modern Japan by focusing on the interface between distinct forms of literary and visual representation and the configuration of social order (the status hierarchy and the division of labor), as well as moral and ideological discourses that were conducive to the reproduction of the order. Central to the forms of representation in Edo popular culture was the overarching literary and artistic principle, which I call a phrase (...) adapted from M.M. Bakhtin's work on Fyodor Dostoevsky. By creating a dialogical interaction of divergent voices and perspectives, Edo popular culture created pluralized, contentious images of Tokugawa society, images that underlined contradictory realities that had become widely discernible around the turn of the eighteenth century. The most salient of all the contradictions was the growing disjuncture between the ideological premise of social and economic hierarchies and their actual reversals. The dialogic imagination captured and accentuated the fluid and dynamic social interactions that threw the formal arrangements of social order into disarray, as well as the widely perceived tensions originating from these interactions, by supplying images that sharply contrasted with those that the Tokugawa authorities worked hard to foster and defend: of a harmonious, self-contained, and perfectly functioning society.

We build a multiple hierarchical model of a representative democracy in which citizens elect ward representatives, ward representatives elect county representatives, county representatives elect state representatives, and state representatives elect a prime minister. We use our model to show that the policy determined by the final representative can become more extreme as the number of hierarchical levels increases as a result of increased opportunities for gerrymandering. Thus, a sufficiently large number of voters provide a district maker an advantage, enabling her (...) to implement her favorite policy. (shrink)

Recently, agent technologies have attracted a lot of interest as an emerging programming paradigm. With such agent technologies, services are provided through collaboration among agents. At the same time, the spread of mobile technologies and communication infrastructures has made it possible to access the network anytime and from anywhere. Using agents and mobile technologies to realize ubiquitous computing systems, we propose a new framework based on KODAMA and VPC. KODAMA provides distributed management mechanisms by using the concept of community and (...) communication infrastructure to deliver messages among agents without agents being aware of the physical network. VPC provides a method of defining peer-to-peer services based on agent communication with policy packages. By merging the characteristics of both KODAMA and VPC functions, we propose a new framework for ubiquitous computing environments. It provides distributed management functions according to the concept of agent communities, agent communications which are abstracted from the physical environment, and agent collaboration with policy packages. Using our new framework, we conducted a large-scale experiment in shopping malls in Nagoya, which sent advertisement e-mails to users' cellular phones according to user location and attributes. The empirical results showed that our new framework worked effectively for sales in shopping malls. (shrink)

Previous research suggested a role of gaze in preference formation, not merely as an expression of preference, but also as a causal influence. According to the gaze cascade hypothesis, the longer subjects look at an item, the more likely they are to develop a preference for it. However, to date the connection between viewing and liking has been investigated predominately with self-paced viewing conditions in which the subjects were required to select certain items from simultaneously presented stimuli on the basis (...) of perceived visual attractiveness. Such conditions might promote a default, but non-mandatory connection between viewing and liking. To explore whether the connection is separable, we examined the evaluative processing of single naturalistic food images in a 2 x 2 design, conducted completely within subjects, in which we varied both the type of exposure (self-paced versus time-controlled) and the type of evaluation (non-exclusive versus exclusive). In the self-paced exclusive evaluation, longer viewing was associated with a higher likelihood of a positive evaluation. However, in the self-paced non-exclusive evaluation, the trend reversed such that longer viewing durations were associated with lesser ratings. Furthermore, in the time-controlled tasks, both with non-exclusive and exclusive evaluation, there was no significant relationship between the viewing duration and the evaluation. The overall pattern of results was consistent for viewing times measured in terms of exposure duration (i.e., the duration of stimulus presentation on the screen) and in terms of actual gaze duration (i.e., the amount of time the subject effectively gazed at the stimulus on the screen). The data indicated that viewing does not intrinsically lead to a higher evaluation when evaluating single food images; instead, the relationship between viewing duration and evaluation depends on the type of task. We suggest that self-determination of exposure duration may be a prerequisite for any influence from viewing time on evaluative processing, regardless of whether the influence is facilitative. Moreover, the purported facilitative link between viewing and liking appears to be limited to exclusive evaluation, when only a restricted number of items can be included in a chosen set. (shrink)

We investigated whether the inferior parietal lobule (IPL) responds in real-time to multisensory inconsistency during movement. The IPL is thought to be involved in both the detection of inconsistencies in multisensory information obtained during movement and that obtained during self-other discrimination. However, because of the limited temporal resolution of conventional neuroimaging techniques, it is difficult to distinguish IPL activity during movement from that during self-other discrimination. We simultaneously conducted electroencephalography (EEG) and near-infrared spectroscopy (NIRS) with the goal of examining IPL (...) activity with a high spatiotemporal resolution during single reaching movements. Under a visual feedback-delay condition, gamma event-related synchronization (γ-ERS), i.e., an increase in gamma (31–47 Hz) EEG power, occurred during reaching movements. This γ-ERS is considered to reflect processing of information about prediction errors. To integrate this temporal information with spatial information from the NIRS signals, we developed a new analysis technique that enabled estimation of the regions that show a hemodynamic response characterized by EEG fluctuation present in the visual feedback-delay condition. As a result, IPL activity was explained by γ-ERS specific to visual feedback delay during movements. Thus, we succeeded in demonstrating real-time activation of the IPL in response to multisensory inconsistency. However, we did not find any correlation between either IPL activity or γ-ERS with the sense of agency. Therefore, our results suggest that while the IPL is influenced by prediction error signals, it does not engage in direct processing underlying the conscious experience of making a movement, which is the foundation of self-other discrimination.

We conduct an online survey experiment to determine the influence of multifunctionality recognition in agriculture on the price premiums of environmental-friendly agricultural products. We use the case of fish-friendly rice produced in Shiga prefecture, Japan, which contributes to the conservation of the water and ecosystem in rural areas around Lake Biwa by setting up fish ways and reducing the use of herbicides. We assume two conditions for consumers to pay premiums on environmental-friendly agricultural products. The first is that consumers recognize (...) multifunctionality in agriculture. The second condition is that consumers have a correct understanding of environment-friendly agricultural products. We thus examine the effects of respondents’ attributes on their responses to two types of visual stimuli: one associated with the multifunctionality of agriculture and information about environment-friendly agricultural products. In the analysis of the respondents; willingness to pay, the price premium of the group with both the stimulus and information is significantly higher than the price premium of the control group with no interventions. However, the price premium of the group with only the stimulus is not statistically different for the control group. The policy implication of this research is that consumers are more likely to support agri-environmental policies if they recognize both the multifunctionality of agriculture and the properties of environmental-friendly agricultural products. The two types of stimuli have complimentary effects on increasing price premiums. Promoting the recognition of multifunctionality is especially important for those who do not usually access information on agriculture. (shrink)

Specificities of enzymes involved in plant specialized metabolism, including flavonoid biosynthesis, are generally promiscuous. This enzyme promiscuity has served as an evolutionary basis for new enzyme functions and metabolic pathways in land plants adapting to environmental challenges. This phenomenon may lead, however, to inefficiency in specialized metabolism and adversely affect metabolite‐mediated plant survival. How plants manage enzyme promiscuity for efficient specialized metabolism is, thus, an open question. Recent studies of flavonoid biosynthesis addressing this issue have revealed a conserved strategy, namely, (...) a homolog of chalcone isomerase with no catalytic activity binds to chalcone synthase, a key flavonoid pathway enzyme, to narrow (or rectify) the enzyme's highly promiscuous product specificity. Reducing promiscuity via specific protein–protein interactions among metabolic enzymes and proteins may be a solution adopted by land plants to achieve efficient operation of specialized metabolism, while the intrinsic promiscuity of enzymes has likely been retained incidentally.

In their examination of elementary science classrooms, Amerine and Bilmes (1988) found that following instructions requires students to understand the relationship between the projected outcome and the corresponding course of actions. One of the most important resources for instructions is the lesson plan, which prescribes the sequence of teaching. However, there is often a gap between what is planned and what actually happens in the classroom. This raises the question of how teachers come to terms with contingent variants and unexpected (...) outcomes that real-time interactions occasion and how lesson plans are configured into these processes. This study examines a teacher education program that uses lesson plans as a central resource for teaching mathematics. The results suggest that classroom teachers use lesson plans as communicative resources to identify problems, specify assumptions about their teaching and act on the evolving contingency of classroom interaction. The interactional contingency is the locus of teaching practices, not an obstacle to the application of procedures in lesson plans. (shrink)

We study L∞κ-freeness in the variety of Boolean algebras. It is shown that some of the theorems on L∞κ-free algebras which are known to hold in varieties such as groups, abelian groups etc. are also true for Boolean algebras. But we also investigate properties such as the ccc of L∞κ-free Boolean algebras which have no counterpart in the varieties above.

Psychological research on people’s understanding of natural language connectives has traditionally used truth table tasks, in which participants evaluate the truth or falsity of a compound sentence given the truth or falsity of its components in the framework of propositional logic. One perplexing result concerned the indicative conditional if A then C which was often evaluated as true when A and C are true, false when A is true and C is false but irrelevant“ (devoid of value) when A is (...) false (whatever the value of C). This was called the “psychological defective table of the conditional.” Here we show that far from being anomalous the “defective” table pattern reveals a coherent semantics for the basic connectives of natural language in a trivalent framework. This was done by establishing participants’ truth tables for negation, conjunction, disjunction, conditional, and biconditional, when they were presented with statements that could be certainly true, certainly false, or neither. We review systems of three-valued tables from logic, linguistics, foundations of quantum mechanics, philosophical logic, and artificial intelligence, to see whether one of these systems adequately describes people’s interpretations of natural language connectives. We find that de Finetti’s (1936/1995) three-valued system is the best approximation to participants’ truth tables. (shrink)

A 10 kHz pulsed X-ray generator utilising a hot-cathode triode in conjunction with a new type of grid control device for controlling X-ray duration is described. The energy-storage condenser was charged up to 70 kV by a power supply, and the electric charges in the condenser were discharged to the X-ray tube repetitively by the grid control device. The maximum values of the grid voltage, the tube voltage, and the tube current were −1.5 kV, 70 kV, and 0.4 A, respectively. (...) The duration of the flash X-ray pulse was primarily determined by the time constant of the grid control device and the cut-off voltage of thermoelectrons. The X-ray duration was controlled within a region of less than 1 ms; the X-ray intensity with a pulse width of 0.27 ms, a charged voltage of 70 kV, and a peak tube current of 0.4 A was 0.92 μC kg −1 at 0.5 m per pulse. The maximum repetition rate was about 10 kHz, and the size of the focal spot was about 3.5×3.5 mm. (shrink)

Stigmatization and sharming of healthcare workers in Japan during the coronavirus 2019 pandemic reveal uniquely Japanese features. Seken, usually translated as ‘social appearance or appearance in the eyes of others,’ is a deep undercurrent woven into the fabric of Japanese life. It has led to providers who become ill with the SARS-CoV-2 virus feeling ashamed, while concealing their conditions from coworkers and public health officials. It also has led to healthcare providers being perceived as polluted and their children being told (...) they were not welcome in schools. Although such experiences are not isolated to Japan and have appeared in other parts of the world, the cultural forces driving them in Japan are unique. Overcoming stigmatization and shaming of Japanese healthcare providers will require concerted efforts to understand cultural barriers and to view such practices as raising human rights issues affecting the safety and well-being of all.

We agree that motivation to share emotions and other mental states is crucial for communicative development, but human infants are highly selective in sharing mental states, and this is well taken evolutionarily. Young chimpanzees may also have motivation to imitate mothers. Thus, uniquely human cognition and culture may not be reduced to a few basic abilities and/or inclinations.
