Mueller's gibbons ( Hylobates muelleri ) sing both sex-specific and duet songs. These songs are thought to be involved in territory maintenance, as well as the maintenance of pair or family bonds. However, few observational studies have examined how gibbons interact with their neighbors through song in the wild. We have been conducting field observations of wild gibbon groups in northeast Borneo since 2001. In the Borneo Rainforest Lodge (BRL) and Danum Valley Field Center (DVFC) at the Danum Valley Conservation (...) Area (DVCA), we observed seven episodes of alternating songs between males. Here, we describe the process of song exchange between males. During male interactions, song bouts rarely overlapped and were alternately emitted. Several studies have reported antiphonal vocalizations in New World and Old World primate species, but rarely in apes. Our observations of antiphonal songs in gibbons indicate that gibbons not only unilaterally advertise information, but also interactively communicate with neighbors and family members through songs. Since gibbons are phylogenetically similar to humans, and turn-taking has an important role in human conversation, our research on gibbon communication may provide insight into the evolution of human language.

Understanding whether the long and elaborate songs of male gibbons have syntax and hierarchical structures is an interesting question in the evolution of language, because gibbons are near humans in the phylogenetic tree and a hierarchically organized syntax is considered to be a basic component of human language. We conducted field research at Danum Valley Conservation Area in northern Borneo to test the hypothesis that gibbon songs have syntax and chunks. We followed one Mueller’s gibbon group for 1 week in (...) the dry and rainy seasons every year from 2001 to 2009, collecting vocal and behavioral data. Results show that songs emitted by the studied male gibbon were governed by combinatory rules. Some context-dependent songs had different combinatory rules, although they overlapped with the songs whose contexts were uncertain. The male Mueller’s songs had characteristics that suggest existence of chunk structure. These results provided an important perspective in the study of language origin. (shrink)

Mating activity of a wild Mueller’s gibbon group was observed in the Danum Valley Conservation Area, Sabah, Malaysia. The purpose of this study was to investigate the function of copulation calls in gibbons. The female emitted copulation calls at the time of intromission and pelvic thrusting. Copulation calls were composed of two notes and one of them was sung only while mating. Approximately half of copulation calls were sung near the range boundary. Mating with copulation calls sometimes occurred while singing. (...) According to the model that female copulation calls have evolved under the selective pressures of risk of infanticide and sperm competition, copulation calls should be rare in species with little female promiscuity. As gibbons usually live in pair-living social organization and have a monogamous mating system, no vocal signals by female gibbons are considered to be needed. However, clear copulation calls were emitted by the female. It suggests that the relationship between paired gibbons is unstable. Copulation calls by the female Mueller’s gibbon may function to increase mate guarding and strengthen the pair bond. (shrink)

German Idealism was introduced to Japanese intellectuals in the middle of Meiji era and was mainly received from a mystical or religious perspective, as we see in Inoue Tetsujirō’s “harmonious existence,” Inoue Enryō’s “unity of mind and body,” and Kiyozawa Manshi’s “existentialism.” Since these theories envisioned true reality as a unified and living whole, I group them under the label “philosophy of organism” and from (...) there argue that their conviction that “all is truth and truth is all” was shaped in large part by the Awakening of Faith in the Mahayana. The understanding of Buddhist concepts by Meiji philosophers was philosophical in its content, and those who devoted themselves to the study of Western philosophy were encouraged to describe Eastern thought in Western philosophical terms. As a result, the philosophical world of the Meiji era developed an original standpoint that unified Eastern and Western perspectives by means of a logic of “phenomena-in-reality.”. (shrink)

Fuzzy logic has become an important tool for a number of different applications ranging from the control of engineering systems to artificial intelligence. In this concise introduction, the author presents a succinct guide to the basic ideas of fuzzy logic, fuzzy sets, fuzzy relations, and fuzzy reasoning, and shows how they may be applied. The book culminates in a chapter which describes fuzzy logic control: the design of intelligent control systems using fuzzy if-then rules which make use of human knowledge (...) and experience to behave in a manner similar to a human controller. Throughout, the level of mathematical knowledge required is kept basic and the concepts are illustrated with numerous diagrams to aid in comprehension. As a result, all those curious to know more about fuzzy concepts and their real-world application will find this a good place to start. (shrink)

In political philosophy, reflective equilibrium is a standard method used to systematically reconcile intuitive judgments with theoretical principles. In this paper, we propose that survey experiments and a model selection method—i.e., the Akaike Information Criterion (AIC)-based model selection method—can be viewed together as a methodological means of satisfying the epistemic desiderata implicit in reflective equilibrium. To show this, we conduct a survey experiment on two theories of distributive justice, prioritarianism and sufficientarianism. Our experimental test case and AIC-based model selection method (...) demonstrate that the refined sufficientarian principle, a widely accepted principle of distributive justice, is no more plausible than the prioritarian principle. This tells us that some changes of certain intuitions revolving around sufficientarianism should be examined (separately) based on the findings of the survey experiment and AIC model selection. This shows the potential of our approach—both practically and methodologically—as a novel way of applying reflective equilibrium in political philosophy. (shrink)

This theoretical paper develops a conceptual framework that explains how companies can influence consumer behavior in terms of both social and business benefits through their corporate social marketing initiatives. Drawing from the source credibility literature, the article asserts that the effectiveness of CSM depends largely on the corporate credibility of a company in supporting a social cause. Based on this assertion, the framework identifies ten different antecedents of CSM credibility, which are organized into attributes of the company, attributes of the (...) CSM initiative, and attributes of the cause. Furthermore, this framework shows that CSM credibility affects the two examined consequences, intended prosocial behavior and consumer loyalty. Several research and managerial implications are developed based on the propositions specified in the framework. (shrink)

It is often argued that relational egalitarianism has a fundamental problem with intergenerational justice when compared to other theories of justice such as utilitarianism, prioritarianism, and luck egalitarianism. Recently, Timothy Sommers argued that there is no such comparative disadvantage for relational egalitarianism. His argument is quite modest: it merely aims to reject the claim that there could be no way to extend relational egalitarianism to intergenerational justice. This may be called the ‘No Comparative Disadvantage Thesis’. The present article challenges Sommers’s (...) argument in two ways. First, I show that Sommers fails to provide a reasonable constraint on causal efficacy, which is crucial to his argument for our relation (not relationship) to future generations. Second, I show that the chain-relatedness problem casts a shadow over Sommers’s argument for the No Comparative Disadvantage Thesis. More specifically, compared to the other theories of justice, relational egalitarianism (as it stands) can less easily justify that present persons have duties to future others. This is because relational egalitarianism cannot appeal to a specific principle in regard to the duties in question, because its principle is sensitive to current context and practice. I conclude that the No Comparative Disadvantage Thesis does not hold much promise. (shrink)

The Christian philosopher Muto Kazuo contributed substantially to the predominantly Buddhist “Kyoto School of Philosophy.” Through critical exchange with its representatives, he opened up new perceptions of Christian faith, enabled mutual understanding between Buddhism and Christianity, and challenged the Western dialectical method.

The issue of distributive justice receives substantial amount of attention in our society. On the one hand, we are sensitive to whether and the extent to which people are responsible for being worse off. On the other hand, we are mindful of society’s worst-off members. There has been a debate over luck egalitarianism, which relates to the former concern, and relational egalitarianism, which echoes the latter. By investigating the psychological processes of these two concerns, this paper examines the reliability of (...) the argument that Elizabeth Anderson, a renowned relational egalitarian, presents against luck egalitarianism and for relational egalitarianism. It also considers whether it is possible to support luck egalitarianism and relational egalitarianism simultaneously, using an online experiment. The results of the experiment show that, first, for ordinary people, the luck consideration is as important as the basic capabilities consideration. Second, while real people consider the degree of compensation through the factors of causality and responsibility, the lack of basic capabilities directs them to determine how much victims of bad luck should be compensated. This suggests that pluralist egalitarianism is on the right track. (shrink)

A dialectical contradiction can be appropriately described within the framework of classical formal logic. It is in harmony with the law of noncontradiction. According to our definition, two theories make up a dialectical contradiction if each of them is consistent and their union is inconsistent. It can happen that each of these two theories has an intended model. Plenty of examples are to be found in the history of science.

Centrosomes are the main microtubule organizing centers in animal cells. In particular during embryogenesis, they ensure faithful spindle formation and proper cell divisions. As metazoan centrosomes are eliminated during oogenesis, they have to be reassembled upon fertilization. Most metazoans use the sperm centrioles as templates for new centrosome biogenesis while the egg's cytoplasm re-prepares all components for on-going centrosome duplication in rapidly dividing embryonic cells. We discuss our knowledge and the experimental challenges to analyze zygotic centrosome reformation, which requires genetic (...) experiments to enable scrutinizing respective male and female contributions. Male and female knockout animals and mRNA injection to mimic maternal expression of centrosomal proteins could point a way to the systematic molecular dissection of the process. The most recent data suggest that timely expression of centrosome components in oocytes is the key to zygotic centrosome reformation that uses male sperm as coordinators for de novo centrosome production. Centrosome reformation at fertilization is essential for metazoan development. It requires a complicated interplay of sperm centrioles and the cytoplasm of the oocyte, which has eliminated its centrioles during oogenesis. The male centrioles launch centrosome duplication using female centrosome proteins for the first metazoan cell divisions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 2, November 2003, pp. 205-221 The Origin of the Indirect Passions in the Treatise: An Analogy between Books 1 and 2 HARUKOINOUE 1. The Analogy Between Book 1 and Book 2 If the central design of the Treatise is to demonstrate that "the subjects of the Understanding and Passions make a complete chain of reasoning by themselves" (T 2; SBN xii), as Hume advertises, (...) it seems unquestionable that his intention lies in the illustration of the human mind as an integrated system dependent upon the cooperation of the understanding and the passions, which are discussed separately in Book 1 and Book 2, respectively.1 What is yet to be determined is whether any internal or systematic connection between these two books was originally intended by the author. Is it too fanciful to agree with John Passmore, and to suggest that some dynamic system of the human mind would emerge when we open the door which stands between the first two books?2 The key for this door seems to be found in Hume's account of personal identity. We may well remember how he distinguished two aspects of our identity, one regarding the understanding and another regarding the passions, and claimed that the latter "serves to corroborate" the former "by the making our distant perceptions influence each other, and by giving us a present concern for our past or future pains or pleasures" (T 1.4.6.19; SBN Haruko Inoue is Professor of Philosophy, Sapporo University 3-7-3-1 Toyohira-ku, Sapporo 062-8520, Japan. e-mail: [email protected] 206 Haruko Inoue 261). It seems reasonable to agree with Jane Mclntyre, who suggests that "Hume recognized questions about personal identity not addressed in Book 1, and that Book 2 makes an important contribution to our understanding of Hume's account of the self and its identity."3 And once we get a good understanding of this integrated mechanism of the human mind operating with both wheels, as it were, of the imagination and the passions, all we have to do is to accept his invitation and enjoy the efficiency of this two-wheeled car, driving through the fields of "Morals, Politics, and Criticism." For, if we take his words in his Advertisement seriously,4 it seems quite likely that the Treatise was published first as a set of Book 1 and Book 2, as Passmore suggests,5 and that Book 3 was written as the demonstration of the consistency of his system through the application of the hypothesis established in the first two books. This paper is a modest attempt to illustrate the intimate connection between Book 1 and Book 2: the latter, planned as a proof and reinforcement of the system Hume had established in Book 1, depends on the former. His basic strategy in the Treatise is to explain both systems of the mind by means of the easy transition of the imagination, which connects different perceptions with each other according to two kinds of principles or "properties of human nature " (T 2.1.4.2; SBN 283), viz. "the association both of impressions and ideas, and the mutual assistance they lend each other" (T 2.1.5.5; SBN 284). In Book 1 Hume establishes the system of the understanding in terms of the first association, viz. the association of ideas, and in Book 2 he proceeds to illustrate the system of passions by involving not only the second association but also the concurrence of both kinds of association which he calls "a double relation of impressions and ideas." His basic strategy is thus to apply the same method of reasoning to the illustration of both systems, assuming that "there is an attraction or association among impressions, as well as among ideas" (T 2.1.4.3; SBN 283). The intimate connection between the two systems of the understanding and the passions is illustrated through the demonstration of the "influence of the imagination upon the passions" (T 2.3.6.1; SBN 424), or in terms of the dependence of the latter on the former. It is owing to the dependence of the association of... (shrink)
