There are many gene families that are specific to multicellular animals. These have either diverged from ancestral genes that are shared with fungi and/or plants or evolved from an ancestral gene unique to animals. The evolution of gene families involved in cell–cell communication and developmental control has been studied to establish whether the number of member genes increased dramatically immediately prior to or in concert with the Cambrian explosion. A molecular phylogeny‐based analysis of several animal‐specific gene families has revealed that (...) gene diversification by duplication occurred during two active periods interrupted by a long intervening quiescent period. Intriguingly, the Cambrian explosion is situated in the silent period, indicating that there is no direct link between the first burst of gene diversification and the Cambrian explosion itself. The importance of gene recruitment as a possible molecular mechanism for morphological diversity, and its possible role for the Cambrian explosion, are discussed.

It has been reported as a robust effect that people are likely to select a matching case in the Wason selection task. For example, they usually select the 5 case, in the Wason selection task with the conditional "if an E, then a not-5". This was explained by the matching bias account that people are likely to regard a matching case as relevant to the truth of the conditional (Evans, 1998). However, because a positive concept usually constructs a smaller set (...) than its negative one does (a rarity assumption), it is more effective to get information on the truth of the conditional in a positive set than in a negative set. Thus the optimal data selection account can also explain the effect. The set size of Q and matching by introducing negation were manipulated independently in four experiments. From the results it was inferred that the so-called matching bias was an amalgam of two different cognitive components-relevance judgement by matching and optimal data selection. (shrink)

What is the meaning of “Japanese” culture? In earlier ages, it was about temples, Noh plays, Kabuki, Utamaro and Wabi-sabi. These traditional icons have, since the Meiji era (1868-1912), been identified as typically Japanese. Are they, however, still relevant today? Has there been any crucial mutation in the cultural identity of Japan? In the contemporary era, more and more people associate Japanese culture with Manga, animation and video games, in other words with cultural developments of the post-World War II era. (...) The Japanese Government has actively promoted the popularity of these new aspects of Japanese culture as evidenced in their eagerness to adopt the expression “Cool Japan,” inspired by its British predecessor’s “Cool Britannia.” Everyone does not share that perception though. Following the 11th March 2011 series of disasters, Japanese artist Tadasu Takamine (1968-) worked on a critical questioning of Japanese society and culture, culminating in a work titled Tadasu Takamine's Cool Japan that was shown at the Art Tower Mito, in Ibaraki Prefecture (2012). The present essay reflects on and develops further the message conveyed by Takamine about contemporary Japanese cultural identity. (shrink)

It is known that there is a close relation between Prikry forcing and the iteration of ultrapowers: If U is a normal ultrafilter on a measurable cardinal κ and 〈Mn, jm,n | m ≤ n ≤ ω〉 is the iteration of ultrapowers of V by U, then the sequence of critical points 〈j0,n | n ∈ ω〉 is a Prikry generic sequence over Mω. In this paper we generalize this for normal precipitous filters.

L’exposition d’art dans des paysages est devenu populaire au Japon, avec la multiplication récente de festivals d’art locaux. Dans ces festivals, qui attirent chacun des centaines de milliers de visiteurs, coexistent des œuvres hétérogènes. Certaines sont des sculptures autonomes, d’autres des installations qui se fondent dans le paysage, et d’autres encore sont des œuvres de type « art relationnel ». Bien que ces œuvres in situ affirment leur lien essentiel avec le site naturel rural et avec le corps du spectateur (...) — constituant un événement, une expérience, une rencontre éphémère —, les relations avec le site comme avec le visiteur sont complexes et ambigües. Il y a des œuvres in situ, mais parfois aussi in aliquo situ : des œuvres qui peuvent être installées n’importe où. Qu’est-ce qui attire les visiteurs dans ces expositions? Quels sont donc la nature et le mérite de leur localisation? Si les visiteurs apprécient de voir des œuvres dans ces paysages cela peut être en partie lié au principe japonais traditionnel d’expérience des lieux dit meisho-meguri, ou « pèlerinage vers des sites célèbres ». Cette pratique issue du Moyen Âge est associée historiquement au sacré. Aujourd’hui ce pèlerinage prend la forme du tourisme moderne mais conserve un sens traditionnel invisible car les visiteurs se déplacent à travers une série de lieux géographiques selon un jeu culturellement codé. Selon nous, dans le cas des visites d’œuvres d’art en zones rurales, l’appréciation des œuvres d’art participe à ce même jeu traditionnel de se déplacer physiquement dans une série de lieux. Cette dimension spirituelle implicite modifie à son tour la perception des œuvres. Ainsi on dira que la pratique japonaise de visiter ces expositions d’art in situ témoigne de la survivance d’une tradition, et constitue ainsi un système alternatif d’expérience esthétique. The installations of artwork in natural landscapes have become popular in Japan with the recent increase in local art festivals. In these art festivals where hundreds of thousands of visitors gather, heterogeneous installations coexist; some are autonomous sculptures, some are fused into the natural landscape, and some belong to “relational art”. Although most works assert the essential quality of their location, and the experience as “an event”, their relationships to the rural areas and to the body of the visitor are complex and ambiguous. Some works are really in situ, but some are in aliquo situ—that is, works that could be installed anywhere. What attracts visitors to these exhibitions? Hence what is the nature and merit of the location? What is the relation to the visitor’s bodily presence? If visitors enjoy the site-specificity of the artwork this may be linked to the traditional Japanese system of experiencing places as meisho-meguri—i.e. “a pilgrimage to a series of famous sites”. This practice comes from the Middle Ages and was by then spiritual. While today these pilgrimages appear as a form of modern tourism, they retain a culturally coded character because visitors’s journey is like “a game of visiting a series of geographical places”. According to me, in the case of the visit of artistic sites, the appreciation of the artwork participates in this same game of bodily displacement to a series of places. This implicit spiritual underpinning conversely modifies the visitor’s perception of the works. Thus I propose that visiting artistic sites in natural settings in Japan appears as informed by this Japanese particular tradition, and thus constitutes an alternative system of contemporary aesthetic experience.

Minami–Sakai :883–898, 2016) investigated the cofinal types of the Katětov and the Katětov–Blass orders on the family of all \ ideals. In this paper we discuss these orders on analytic P-ideals and Borel ideals. We prove the following:The family of all analytic P-ideals has the largest element with respect to the Katětov and the Katětov–Blass orders.The family of all Borel ideals is countably upward directed with respect to the Katětov and the Katětov–Blass orders. In the course of the proof of (...) the latter result, we also prove that for any analytic ideal \ there is a Borel ideal \ with \. (shrink)

We investigate how weak square principles are denied by Chang’s Conjecture and its generalizations.

I examine the tension between biopolitics and necropolitics through three themes that I have perceived and that are related to my life in Japan. First, I examine the transformation of hospitals and medical care, particularly for the elderly, through my experience of sharing the end of my mother’s life. Modern medicine has made great achievements in treating diseases that used to be fatal, but it has become institutionalized in the context of Big Pharma interests, with no insight into the natural (...) ageing and death of human beings. Second, I discuss how the ecological worldview on parasitism and symbiosis has been distorted by industrial logic, drawing on the work of my esteemed friend and parasitologist Professor Koichiro Fujita, who passed away in 2021. Finally, with regard to the Covid-19 pandemic, I would argue that it is not a sudden phenomenon triggered by a new virus, but in a sense a disaster that has been prepared for decades and must be seen as a war using bioengineering and epidemiology as weapons, rather than tanks and bombs.

A proof is given for the theorem that at least one bound state exists in a one-dimensional attractive potential however weak it may be. The proof is constructive in that it provides a method to explicitly solve the eigenvalue problem for the eigenvalues as well as the eigenfunctions. The method is well suited to precise numerical calculations.

We study the relationship between the semistationary reflection principle and stationary reflection principles. We show that for all regular cardinals Λ ≥ ω₂ the semistationary reflection principle in the space [Λ](1) implies that every stationary subset of $E_{\omega}^{\lambda}\coloneq \{\alpha \in \lambda \,|\,{\rm cf}(\alpha)=\omega \}$ reflects. We also show that for all cardinals Λ ≥ ω₃ the semistationary reflection principle in [Λ](1) does not imply the stationary reflection principle in [Λ](1).

Since the first half of the nineteenth century in which English was introduced as the language of higher education in India, the word and concept of “philosophy” has played an important role in Indian intellectual life. First the study of philosophy must have meant the study of Western philosophy in Indian universities, butlater various attempts were made to discover the Indian versions of philosophical traditions in Sanskrit literature. Today no one doubts that there has been a rich and very long (...) tradition of such intellectual activities as are fully compatible with what European philosophers have actually been doing. Nevertheless, it is sometimes very difficult to draw a strict line between philosophy and religion in Indian thought. The present study will focus on that passage of the Nyāyamañjarī by a Kashmirian Nyāya scholar Jayanta which deals with the justification of the authority of the Vedas and other religious scriptures. From the analysis of the passage we may detect that there are two different dimensions in his application of logic for this issue. On the one hand he appeals to logical thinking for the defence of the Vedic authority and tries to establish the proper proof. But on the other hand he seems to be conscious of the limitation of reasoning, for he refers to those thinkers without refuting them in the latter half of the passage, according to whom every religious scripture must be accepted as valid insofar as the path of reasoning and argumentation is taken.

This paper examines the role of a proper opponent (phyi rgol yang dag) in debate from the standpoint of the Tibetan Buddhist theory of argumentation. A proper opponent is a person who is engaged in the process of truth-seeking. He is not a debater who undertakes to refute the tenets of a proponent. But rather, he is the model debater to whom a proponent can teach truth by using a probative argument in the most effective way. A proper opponent is (...) thus the model thinker conceived by Tibetan Buddhist scholars, especially by the dGe lugs pa exegetes, to explain the idea of “inference for others.” The term phyi rgol yang dag figures in many text books of the dGe lugs pa school. And the germ of the dGe lugs pa's idea of ``proper opponent'' is found in early Tibetan tshad ma literature, too. The present paper shows that the dGe lugs pa scholars are largely concerned with the process by which one obtains an inferential knowledge about the unknown object, and also that they, when talking about a proper opponent, emphasize the pedagogical role of dialectic conversation rather than the competitive feature of debates.
