This book constitutes the thoroughly refereed joint post-proceedings of three international workshops organized by the Japanese Society for Artificial Intelligence, held in Tokyo, Japan in June 2006 during the 20th Annual Conference JSAI 2006. The volume starts with eight award winning papers of the JSAI 2006 main conference that are presented along with the 21 revised full workshop papers, carefully reviewed and selected for inclusion in the volume.

Replication forks inevitably stall at damaged DNA in every cell cycle. The ability to overcome DNA lesions is an essential feature of the replication machinery. A variety of specialized polymerases have recently been discovered, which enable cells to replicate past various forms of damage by a process termed translesion synthesis. Alternatively, homologous recombination can be used to restart DNA replication across the lesion. Genetic and biochemical studies have shed light on the impact of these two post‐replication repair pathways in bacteria (...) and yeast. In vertebrates, however, a genetic approach to study post‐replication repair has been compromised because many of the genes involved appear to be essential for embryonic development. We have taken advantage of the chicken cell line DT40 to perform a genetic analysis of translesion synthesis and homologous recombination and to characterize genetic interactions between these two pathways in vertebrates. In this article, we aim to summarize our current understanding of post‐replication repair in DT40 in the perspective of bacterial, yeast and mammalian genetics.

This article reports an interesting link between the psychophysical property of intentional control of perceptual switching and the underlying neural activities. First, we revealed that the timing of perceptual switching for a dynamical dot quartet can be controlled by the observers' intention, without eye movement. However, there is a clear limitation to this control, such that each animation frame of the stimulus must be presented for a sufficiently long time length; in other words, the frequency of the stimulus alternation must (...) be sufficiently slow for the control. The typical stimulus onset asynchrony for a 50% level of success was about 275 ms for an average of 10 observers. On the basis of psychophysical property, we designed three experiments for investigating the neural process with a magnetoencephalography. They revealed that: (1) a peak component occurring about 300 ms after a reversal was stronger when the direction of perceived motion was switched intentionally than when it was not switched, and (2) neural components about 30–40 ms and 240–250 ms after the reversal of the stimulus animation were stronger when perception was altered intentionally than when it was switched unintentionally. The 300 ms component is consistent with a previous study about passive perceptual switching (Struber and Herrmann [2002]: Cogn Brain Res 14:370–382), but the intentional effect was seemed to be a different component from the well-known P300 component.

The aim of this paper is to propose an antithesis to the overreliance on scientific facts and objectivity to counter mis- and disinformation in media literacy education. Through conceptual examination of meaning, care, and facts, I demonstrate the ontological priority of meaning and values in the life-world. I then discuss conspiracy theories as a textual genre in which the crisis of meaning manifests as a prominent factor. Given the centrality of meaning, I claim that literacy education needs to go beyond (...) the matters of fact and address matters of concern in this supposedly post-truth world. (shrink)

TOPOLOGIE DES LOGOS UND KANT-INTERPRET A TION § I. Topologie des Logos Die Geschichte der Philosophie ist die Geschichte der Entwicklung des Logos. Jedes System der Philosophie hat seinen Logos. Jedes System der Philosophie, welches seinen Logos hat, ist vom Standpunkte der Entwicklung der Philosophie als Ganzem gesehen eine notwendige Entwicklung des Logos. Die Geschichte der Philosophie ist, wie Hegel sagte, eine Entwicklung des absoluten Geistes. Aber diese Entwicklung des Logos soll man nicht als dialektische Entwicklung, wie Hegel sie sah, (...) bezeichnen. Vielmehr befindet sich das System der Hegelschen Philosophie selber an einer besonderen Stelle der Entwicklung des Logos. Die Entwicklung des Logos ist nicht immer dialektisch-formelle Entwicklung und wird nicht in Dialektik bis zum Äußersten getrieben. Wir müssen uns davor hüten, die Entwicklung des Logos formell dialek tisch zu sehen. Vielmehr müssen wir die Entwicklung des Logos - in der Phase der notwendigen Entwicklung, in der er sich befinde- positiv betrachten. Dialektische Konstruktion der Geschichte der Philosophie auf Kosten der Tatsachen, wie Hegel sie trieb, ist dogma tisch-idealitisches Verhalten, und unser Verhalten soll nicht solches sein. Betrachten wir positiv die Entwicklung des Logos in der Geschich te der Philosophie, so entsteht nicht dialektische Geschichtsauffassung, sondern Topologie der Entwicklung des Logos: kurz, die Topologie des Logo::. Nach der Topologie des Logos wird jedem System der Philoso phie sein Topos in der Entwicklung des Logos als Ganzem gegeben. (shrink)
