ウィトゲンシュタインさんと落語を探検!「粗忽長屋」は“私とは何か”という謎をめぐる物語であり、「堀の内」は“笑いの本質”についての深淵な哲学書。そして「芝浜」には、“わたしたちの世界は夢ではないのか” というテーマが隠されていた...

Researchers have been interested in what retrieval process is responsible for overgeneral autobiographical memories (OGM) in depression. Previous cross-sectional studies demonstrated that, for negatively valenced cues, directly retrieved OGM, rather than generatively retrieved OGM, are associated with depression. However, longitudinal evidence of this relationship is still lacking and needs to be tested. We conducted a re-analysis of the online computerised memory specificity training (c-MeST) data to examine whether directly retrieved OGM for negative cues prospectively predicts high levels of depression 1 (...) month later. Participants who met the criteria of current major depressive disorders (N = 116; n = 58 in the c-MeST group and n = 58 in the control group) recalled autobiographical memories for positive and negative cues and judged each retrieval process (i.e. direct or generative). The results supported our prediction, and directly retrieved OGM for negative cues predicted high levels of depressive symptoms 1 month later even after controlling for the group effect, baseline depressive symptoms, executive functioning and rumination. Exploratory analysis showed that direct retrieval of specific memories prospectively predicted low levels of depression. These results support the theory that elevated accessibility of negatively valenced general memory representations is a vulnerability factor for depressive symptoms. (shrink)

For ${b \in {^{\omega}}{\omega}}$ , let ${\mathfrak{c}^{\exists}_{b, 1}}$ be the minimal number of functions (or slaloms with width 1) to catch every functions below b in infinitely many positions. In this paper, by using the technique of forcing, we construct a generic model in which there are many coefficients ${\mathfrak{c}^{\exists}_{{b_\alpha}, 1}}$ with pairwise different values. In particular, under the assumption that a weakly inaccessible cardinal exists, we can construct a generic model in which there are continuum many coefficients ${\mathfrak{c}^{\exists}_{{b_\alpha}, 1}}$ (...) with pairwise different values. In conjunction with these results, we give a generic model in which there are many Yorioka’s ideals ${\mathcal{I}_{f_\alpha}}$ with pairwise different covering numbers. (shrink)

We review some techniques and notions for quantum information theory. It is shown that the dynamical entropies is discussed and some numerical computations of these entropies are carried for several states.

We review some notions for general quantum entropies. The entropy of the compound systems is discussed and a numerical computation of the quantum dynamical systems is carried for the noisy optical channel.

In 2002, Yorioka introduced the σ-ideal ${{\mathcal {I}}_f}$ for strictly increasing functions f from ω into ω to analyze the cofinality of the strong measure zero ideal. For each f, we study the cardinal coefficients (the additivity, covering number, uniformity and cofinality) of ${{\mathcal {I}}_f}$.

The essay is a written version of a talk Nakamura Yūjirō gave at the College international de philosophie in Paris in 1983. In the talk Nakamura connects the issue of common sense in his own work to that of place in Nishida Kitarō and the creative imagination in Miki Kiyoshi. He presents this connection between the notions of common sense, imagination, and place as constituting one important thread in contemporary Japanese philosophy. He begins by discussing the significance of (...) place (basho) that is being rediscovered today in response to the shortcomings of the modern Western paradigm, and discusses it in its various senses, such as ontological ground or substratum, the body, symbolic space, and linguistic or discursive topos in ancient rhetoric. He then relates this issue to the philosophy of place Nishida developed in the late 1920s, and after providing an explication of Nishida’s theory, discusses it further in light of some linguistic and psychological theories. Nakamura goes on to discuss his own interest in the notion of common sense traceable to Aristotle and its connection to the rhetorical concept of topos, and Miki’s development of the notion of the imagination in the 1930s in response to Nishida’s theory. And in doing so he ties all three—common sense, place, and imagination—together as suggestive of an alternative to the modern Cartesian standpoint of the rational subject that has constituted the traditional paradigm of the modern West.

We propose an efficient algorithm for deciding the reachability between any nodes on XML data represented by connected directed graphs. We develop a technique to reduce the size of the reference table for the reachability test. Using the small table and the standard range labeling method for rooted ordered trees, we show that our algorithm answers almost queries in a constant time preserving the space efficiency and a reasonable preprocessing time.
