In studies of Indian theories of meaning it has been standard procedure to examine their relevance to the ontological issues between Brahmin realism about universals and Buddhist nominalism. It is true that Kumārila makes efforts to secure the real existence of a generic property denoted by a word by criticizing Dignāga, who declares that the real world consists of absolutely unique individuals. The present paper, however, concentrates on the linguistic approaches Dignāga and Kumārila adopt to deny or to prove the (...) existence of universals. It turns out that in spite of adopting contrasting approaches they equally distinguish between the semantic denotation of a word and its pragmatic reference to a thing in the physical world. From a purely semantic viewpoint, Dignāga considers the exclusion of others by a word as the result of a conceptual accumulation of the sense-components accepted in the totality of worldly discourse. Among the three characteristics Dignāga held must be met by universals, Kumārila attaches special importance to their entire inherence in each individual. This is because he pragmatically pays attention to the use of a word in the discourse given in a particular context by analyzing a sentence into a topic and a comment. (shrink)

Dignāga’s theory of semantics called the “theory of apoha ” has been criticized by those who state that it may lead to a circular argument wherein “exclusion of others” is understood as mere double negation. Dignāga, however, does not intend mere double negation by anyāpoha. In his view, the word “cow” for instance, excludes those that do not have the set of features such as a dewlap, horns, and so on, by applying the semantic method called componential analysis. The present (...) paper aims to prove this by referring to the fragments quoted by Jinendrabuddhi and Siddhasenagaṇi. Dignāga logically proves that the denotation of the referent Q by the word “P” cannot be derived from the joint presence of “P” with Q. Instead, he derives it from the joint absence of “P” with the nonexistence of Q. Anyāpoha is nothing but verbal vyatireka. Componential analysis is used for describing what is to be excluded. Dignāga draws taxonomic hierarchies of words based on their customary use, and assumes componential analysis to operate in the background of the hierarchies formed in semantic fields, stating that a general term is restricted to having the same reference with one of its specific terms insofar as the former is connected with the characteristics of the latter’s referent. Moreover, he states that a proper name also denotes its referent by excluding those that do not have the cluster of a certain number of qualities. (shrink)

This paper explores the time-inconsistency problem of audience costs in international disputes. The nature of democracy makes it difficult for leaders to back down from earlier diplomatic positions in an international dispute, out of fear of domestic political costs. Few studies have addressed the temporal aspect of such costs. This study argues that election timing impinges on the extent to which the audience cost mechanism works, and consequently, on state conflict behavior. While competitive elections are central to the political accountability (...) inherent in a democracy, voters typically lack enough opportunities to punish unsatisfactory leaders in a timely way, because of fixed election timing, and also may disregard foreign policy missteps that occurred in the distant past. Democratic leaders therefore have an incentive to choose strategically, with the electoral calendar in mind, when selecting a form of conflict behavior. Leaders can retreat from their demands without paying high audience costs when the upcoming election is in the distant future. To test this argument, the authors conduct a natural experiment featuring territorial disputes between Russia and two Baltic republics – Estonia and Latvia. Despite the commonalities in the disputes, as well as in their political systems and socioeconomic backgrounds, the governments of the two Baltic countries showed a sharp contrast in their diplomatic decisions. This paper argues that only the temporal gap in electoral timing can explain this variation, imparting the ironical implication that frequent democratic elections can obstruct peaceful conflict resolutions, and that excessive democratization may well hinder the very goal of peace.

This paper explores the psychological motivations behind collectivist behavior in Japan and the U.S. Using data from a large-scale questionnaire survey, we examine the causes of collectivist behavior (i.e., group conformity) at workplaces and at home. Our key findings are as follows: (i) in Japan, people conform to their groups, both at work and at home, because they consider that cooperation with others will result in greater achievement; (ii) in both Japan and the U.S., people conform to their groups, both (...) at work and at home, because behaving similarly to others makes them feel comfortable; and (iii) in both Japan and the U.S., people conform to their family’s opinion at home because they value cooperation with family members. Our findings suggest that institutional differences between Japan and the U.S. give rise to the differences in psychological motivations for collectivist behavior. (shrink)

Humans have great locomotor adaptability to environmental demands, which has been investigated using a split-belt treadmill with belts on both the left and right sides. Thus far, neuromuscular control in split-belt locomotor adaptation has been evaluated by analyzing muscle activities at the individual muscle level. Meanwhile, in the motor control field, the muscle synergy concept has been proposed. Muscle synergies are considered the fundamental building blocks of movement and are groups of coactive muscles and time-varying activation patterns, thereby, reflecting the (...) neurophysiological characteristics of movement. To date, it remains unclear how such muscle synergies change during the adaptation and de-adaptation processes on the split-belt treadmill. Hence, we chronologically extracted muscle synergies while walking on the split-belt treadmill and examined changes in the number, muscle weightings, and temporal activation patterns of muscle synergies. Twelve healthy young males participated, and surface electromyography signals were recorded bilaterally from 13 lower-limb muscles. Muscle synergies were extracted by applying non-negative matrix factorization to the EMG data of each leg. We found that during split-belt walking, the number of synergies in the slow leg increased while an extra synergy appeared and disappeared in the fast leg. Additionally, the areas under the temporal activation patterns in several synergies in both legs decreased. When both belts returned to the same speed, a decrease in the number of synergies and an increase in the areas under the temporal activation patterns of several synergies were temporally shown in each leg. Subsequently, the number of synergies and the areas under the temporal activation patterns returned to those of normal walking before split-belt walking. Thus, changes in the number, muscle weightings, and temporal activation patterns of synergies were noted in the split-belt locomotor adaptation, suggesting that the adaptation and de-adaptation occurred at the muscle synergy level.
