We propose a new Real-coded GA(RCGA) using the combination of two crossovers, UNDX-m and EDX. The search region of UNDX-m is biased to the inside area that the population of the RCGA covers. Because of this search bias, the GA using UNDX-m causes stagnation of its search if the cost function has a kind of structure, so called, a ridge structure or a multiple-peak structure. In order to overcome this stagnation, we propose a new crossover EDX, whose search is biased (...) toward extrapolative one. Experimental results show that RCGA with EDX can deal with both ridge-structure function whose dimension reaches more than hundreds and multiple-peak function whose optimum resides at the corner of the search area.

This paper presents the Real-coded Genetic Algorithms(RCGA) which can treat with high-dimensional ill-scaled structures, what is called, k -tablet structure. The k -tablet structure is the landscape that the scale of the fitness function is different between the k -dimensional subspace and the orthogonal (n-k) -dimensional subspace. The search speed of traditional RCGAs degrades when high-dimensional k -tablet structures are included in the landscape of fitness function. In this structure, offspring generated by crossovers is likely to spread wider region than (...) the region where the parental population covers. This phenomenon causes the stagnation of the search. To resolve this problem, we propose a new crossover LUNDX- m, which uses only m -dimensional latent variables. The effectiveness of the proposal method is tested with several benchmark functions including k -tablet structures and we show that our proposal method performs better than traditional crossovers especially when the dimensionality n is higher than 100.

This paper presents a kernel density estimation method by means of real-coded crossovers. Functions of real-coded crossover operators are composed of probabilistic density estimation from parental populations and sampling from estimated models. Real-coded Genetic Algorithm (RCGA) does not explicitly estimate probabilistic distributions, however, probabilistic model estimation is implicitly included in algorithms of real-coded crossovers. Based on this understanding, we exploit the implicit estimation of probabilistic distribution of crossovers as a kernel density estimator. We also propose an application of crossover kernels (...) to Expectation-Maximization estimation (EM) of Gaussian mixtures. (shrink)

Aworkshop was held August 26–28, 2015, by the Earth- Life Science Institute (ELSI) Origins Network (EON, see Appendix I) at the Tokyo Institute of Technology. This meeting gathered a diverse group of around 40 scholars researching the origins of life (OoL) from various perspectives with the intent to find common ground, identify key questions and investigations for progress, and guide EON by suggesting a roadmap of activities. Specific challenges that the attendees were encouraged to address included the following: What key (...) questions, ideas, and investigations should the OoL research community address in the near and long term? How can this community better organize itself and prioritize its efforts? What roles can particular subfields play, and what can ELSI and EON do to facilitate research progress? (See also Appendix II.) The present document is a product of that workshop; a white paper that serves as a record of the discussion that took place and a guide and stimulus to the solution of the most urgent and important issues in the study of the OoL. This paper is not intended to be comprehensive or a balanced representation of the opinions of the entire OoL research community. It is intended to present a number of important position statements that contain many aspirational goals and suggestions as to how progress can be made in understanding the OoL. The key role played in the field by current societies and recurring meetings over the past many decades is fully acknowledged, including the International Society for the Study of the Origin of Life (ISSOL) and its official journal Origins of Life and Evolution of Biospheres, as well as the International Society for Artificial Life (ISAL).

The paper explores the emergence and development of socially responsible investment (SRI) in Japan. SRI is a recent field in Japan. It is not clear which model it will follow: the European, American or its own model. Through the analysis of the historical roots of SRI, the key actors and motivations that have contributed to its diffusion, the paper provides explorative grounds to sketch the translation mechanisms of SRI in Japan and offers insight into its future path. Based on primary (...) and secondary sources of information, the paper shows that although SRI in Japan holds some similarities with the U.S. and especially with the European model, it remains unique. It highlights the importance of translation and re-interpretation in adopting a practice in a new context. SRI in Japan is still in a dynamic construction process. Although we expect it to develop further, it is difficult to depict its future shape and form. (shrink)

This article analyses, both historically and systematically, the underlying causes of specific characteristics of globalism and nationalism in Japan focusing on an ideological moral education that lies at the heart of the problems of Japanese education. The analysis highlights two issues: (1) There is no real globalism in modern Japan. Certainly, the globalization of industry, government, and academia is now loudly proclaimed in Japan. However, in the name of globalization, English education is overemphasized. (2) There is no real nationalism in (...) modern Japan. Japan once had a nationalism centred on the emperor system from the Meiji era. However, after World War II, the emperor system in Japan was dismantled and a democratic Japanese Constitution was enacted under the influence of the Allied Powers. Furthermore, in the Basic Act on Education, the theory of ‘the perfection of personality’ based on Kant’s philosophy was transplanted. Education in post-war Japan developed under a democratic constitution and the Basic Act on Education, which states that the purpose of education is ‘the perfection of personality’. This means that education has a strong moral flavour. Particularly at the stage of compulsory education in Japan, which is the foundation of national education, moral education is addressed through all educational activities at school. Therefore, the issues of globalism and nationalism in moral education, which this article deals with, belong directly to core problems of Japanese education. (shrink)

In this article Kobayashi Toshiaki discusses the importance in all periods of Karatani’s oeuvre of the notion of an “exterior” that necessarily falls beyond the bounds of a system, together with the notion of “singularity” as that which cannot be contained within a “universal.” The existential dread vis-à-vis the uncanny other that Karatani in his early works of literary criticism had initially found to be the underlying tone in Sōseki’s works remained with Karatani himself throughout his career and is (...) what had drawn him closer to philosophy. This sense of the “exterior” to—or other than—the normality of consciousness and the meaningfulness of the world is then extended and applied as the “exterior to systems” in his analyses of logical, mathematical, and linguistic systems, in his reading of Marx’s discussion of capitalist economics, and most recently in his analysis of commodity exchange between communities.

In this chapter, Kobayashi and Marion first provide reasons to reject the many readings of Collingwood that sought to draft him as a participant in the Hempel-Dray debate about the status of covering laws in history. After all, this debate was not part of Collingwood’s context and, although one can pry from his writings a contribution to it, one may simply, by doing so, misunderstand what he was up to. In the second part, they present the Gabbay-Woods Schema for (...) abductive reasoning, as it occurs in the context of inquiry, as triggered by an ignorance problem, and as being ‘ignorance preserving’. They then argue that this allows us better to see the point of Collingwood’s ‘logic of questions and answers’, as derived from his own practice in archaeology, and his use of the ‘detective model of the historian’, as opposed to merely focussing on understanding what ‘re-enactment’ could mean as a contribution to the Hempel-Dray debate.

Tosaka Jun (1900-1945) was one of modern Japan's most unique and important critics of capitalism, the emperor system, imperialism, and everyday life in wartime Japan. This collection of translations contains some of Tosaka's most important essays and original articles on Tosaka.

The purpose of this paper is to clarify Prajñākaragupta’s view of mental perception ( mānasapratyakṣa ), with special emphasis on the relationship between mental perception and self-awareness. Dignāga, in his PS 1.6ab, says: “mental [perception] ( mānasa ) is [of two kinds:] a cognition of an [external] object and awareness of one’s own mental states such as passion.” According to his commentator Jinendrabuddhi, a cognition of an external object and awareness of an internal object such as passion are here equally (...) called ‘mental perception’ in that neither depends on any of the five external sense organs. Dharmakīrti, on the other hand, considers mental perception to be a cognition which arises after sensory perception, and does not call self-awareness ‘mental perception’. According to Prajñākaragupta, mental perception is the cognition which determines an object as ‘this’ ( idam iti jñānam ). Unlike Dharmakīrti, he holds that the mental perception follows not only after the sensory perception of an external object, but also after the awareness of an internal object. The self-awareness which Dignāga calls ‘mental perception’ is for Prajñākaragupta the cognition which determines as ‘this’ an internal object, or an object which consists in a cognition; it is to be differentiated from the cognition which cognizes cognition itself, that is, self-awareness in its original sense.

The propositional fragment L 1 of Leniewski's ontology is the smallest class (of formulas) containing besides all the instances of tautology the formulas of the forms: (a, b) (a, a), (a, b) (b,). (a, c) and (a, b) (b, c). (b, a) being closed under detachment. The purpose of this paper is to furnish another more constructive proof than that given earlier by one of us for: Theorem A is provable in L 1 iff TA is a thesis of first-order (...) predicate logic with equality, where T is a translation of the formulas of L 1 into those of first-order predicate logic with equality such that T(a, b) = FblxFax (Russeltian-type definite description), TA B = TA TB, T A = TA, etc. (shrink)

Social or relational egalitarians try to defend democracy non-instrumentally as a constitutive element of a society where no one stands as inferior or superior to anyone else. However, they face an instrumentalist challenge from within: Why not uphold a non-democratic regime if it outperforms democracy in protecting or promoting egalitarian social relations, for example, by stably producing substantive political decisions that guard against social hierarchies? This article explores the best response to this challenge from the social egalitarian non-instrumentalist standpoint. It (...) argues that the instrumentalist challenge can be accommodated without abandoning the essential non-instrumentalist commitment to democracy; while a nondemocratic regime may be justified under less-than-ideal circumstances as a contingently effective means to realize more social equality, democracy can nevertheless be viewed as a necessary condition for the realization of full social equality.

It has been suggested that preparing to teach and teaching are conditionally effective in enhancing one’s own learning. This paper focuses on interactivity—the level of teacher-student interaction in expected or actual teaching—as the potential key to understanding and controlling the variability in the effectiveness of learning by preparing to teach and teaching. By summarizing and reanalyzing the results of previous studies, I suggest that the learning benefits of studying with the expectation of direct teaching (i.e., teaching a student face-to-face) are (...) greater than those of studying with the expectation of indirect teaching (i.e., teaching a student indirectly by creating a lecture video, providing written explanations, or using other means) and that learning by direct teaching surpasses learning by explaining to oneself or indirect teaching at least after preparing to do so. Next, three candidate explanations for the impact of interactivity are discussed: the advantages of asking and answering questions, obtaining additional information about and from one’s student, and enhancing one’s motivation to process learning material deeply while preparing to teach and teaching. Finally, I conclude with the remaining questions and directions for future research. (shrink)

We argue that the proper context for understanding Collingwood’s The Principles of Art is his claim that it has bearing “upon the condition of art in England in 1937”. We thus argue that he formulated a philosophical argument that underpins avant-garde dramatic poetry and theatrical practices (Eliot, Auden and the Group Theatre), taking his interpretation of Spinoza’s Ethics 5 prop. 3 to be the book’s central thesis: it is through art that one knows, against the ‘corruption of consciousness’, what emotions (...) one feels and recognizes them as one’s own. Collingwood further believed that this could only be achieved through collaboration between the artist and the community, validating new theatrical practices involving interaction with the audience. We analyse these views in the context of England in 1937: in an era marked by the rise of Fascism and Nazism, Collingwood believed that art thus conceived could help restoring emotional support for the defense of liberal democracies. We conclude with an exploration of parallels with and divergences from the Spinozist idea of ‘mobilizing affects’ in contemporary ‘left populism’ (Mouffe). (shrink)

The Fist-Edge-Palm task, a manual hand task, has been used to detect frontal dysfunctions in clinical situations: its performance failures are observed in various prefrontal cortex -related disorders, including schizophrenia. However, previous imaging studies reported that the performance of the FEP task activated motor-related areas, but not the PFC. Here, we aimed to investigate the relationships between the performance of the FEP task and PFC functions. Hemodynamic activity in the PFC, including the dorsolateral PFC and frontal pole, was recorded. Healthy (...) young subjects performed the FEP task as well as a palm tapping task three times. The subjects also completed a Wisconsin Card Sorting Test and Schizotypal Personality Scale questionnaire. We found that hemodynamic activity in the PFC increased in the first trial of the FEP task but decreased considerably in the second and third trials compared to the PT task. The number of performance errors in the FEP task also decreased in the second and third trials. Error reduction in the FEP task between the first and second trials was negatively correlated with schizotypal trait and the number of perseveration errors in the WCST. Furthermore, changes in the PFC hemodynamic activity between the first and second trials were positively correlated with error reduction in the FEP task between the first and second trials, and negatively correlated with the number of perseveration errors in the WCST. These results suggest that learning in the FEP task requires PFC activation, which is negatively associated with perseveration errors in the WCST. The results further suggest that the FEP task, in conjunction with near-infrared spectroscopy, may be useful as a diagnostic method for various disorders with PFC dysfunction. (shrink)

The authors examined cultural preferences for formal versus intuitive reasoning among East Asian (Chinese and Korean), Asian American, and European American university students. We investigated categorization (Studies 1 and 2), conceptual structure (Study 3), and deductive reasoning (Studies 3 and 4). In each study a cognitive conflict was activated between formal and intuitive strategies of reasoning. European Americans, more than Chinese and Koreans, set aside intuition in favor of formal reasoning. Conversely, Chinese and Koreans relied on intuitive strategies more than (...) European Americans. Asian Americans' reasoning was either identical to that of European Americans, or intermediate. Differences emerged against a background of similar reasoning tendencies across cultures in the absence of conflict between formal and intuitive strategies. (shrink)

In particular, as we shall see, Collingwood is often dismissed as having held an indefensible, outmoded ‘ideal’ theory, according to which the work of art is primarily ‘mental’, while his potential role in current debates is simply ignored. I will argue that this view is largely mistaken.

In meinem Aufsatz möchte ich die Ästhetik auf ihre Möglichkeit hin überprüfen, eine grundlegende Theorie des „Sinnlichen" innerhalb der menschlichen kulturellen Tätigkeiten zu sein. Dieses Vorhaben werde ich damit beginnen, Heideggers Kritik an der traditionellen Ästhetik zu behandeln. Dem überlieferten Ästhetikverständnis liegt nach Heidegger offenbar diesselbe vorstellend-vergegenständlichende Denkweise zugrunde, die der ganzen abendländischen Geschichte eigen ist. Doch lässt sich nach Heidegger mittels der auf dem metaphysischen Denken basierenden Ästhetik das Wesen der Kunst niemals erschöpfend behandeln, da die Kunst als das (...) Ins-Werk- Setzen der Wahrheit verstanden werden muss.Freilich nimmt Heidegger immer eine kritische Haltung gegenüber der sogenannte „Ästhetik" ein, aber man kann dadurch auch die Möglichkeit einer anderen erweiterten Ästhetik finden, die die anfängliche Wahrheitsfunktion der aisthesis als Wahr-nehmung ins Auge zu fassen versucht. Von diesem grundlegenden Standpunkt aus möchte ich mich mit einem gegenwärtigen Versuch des ästhetischen Denkens (Wolfgang Welsch) und mit einer nicht-europäischen traditionellen Ästhetik (Shüzö Kuki) beschäftigen.

Cet article examine le rapport entre l’Idée platonicienne du Bien et l’au-delà de l’essence de Levinas.

We investigate stationarity of types over models in simple theories. In particular, we show that in simple theories with finite SU-rank, any complete type over a model having Cantor-Bendixson rank is stationary.

The nucleolus is a region of the nucleus with high protein density and it acts as a ribosome factory. The nucleolus contains a distinct region of the genome, the ribosomal RNA gene repeats (rDNA) that supply ribosomal RNA (rRNA) molecules. The rDNA is the most‐abundant gene and occupies a large part of the genome, for example, there are thousands of rDNA copies in the genomes of plant cells. Therefore, it is natural to suppose that the condition of the rDNA, such (...) as its stability, might affect cellular functions. Here I would like to propose a new model regarding the roles of the rDNA and nucleolus. The key point of this model is that they act to preserve genome stability and trigger aging.
