Dysfunctional attentional control is observed in patients with mental disorders. However, there is no established neurophysiological method to assess attention in such patients. We showed a discrepancy in alpha-band power in the tasks that evoked internal and external attention event-related alpha-band power changes in healthy subjects during self-reflection and working memory tasks in a preliminary study. In this study, we aimed at elucidating event-related alpha-band power changes in healthy subjects during the tasks, addressing the shortcomings of the previous study. Sixteen (...) healthy volunteers were examined for the event-related power change during the tasks. The results demonstrated the discrepancy of alpha-band ERpow at 8, 10, and 12 Hz in the parieto-occipital area between the WM and SR tasks for a period between a target stimulus and a command stimulus, where a participant switched to internal attention from external attention according to the SR task and remained at external attention according to the WM task. The results suggest that alpha-band ERpow in this area is associated with the direction of attention in response to cognitive stimuli, indicating that the findings of ERpow during the two tasks would potentially aid in the clarification of the pathophysiology of the dysfunctional change in attention in patients with psychiatric disorders.

Thirteen up-and-coming researchers in the philosophy of mathematics have been invited to write on what they take to be the right philosophical account of mathematics, examining along the way where they think the philosophy of mathematics is and ought to be going. A rich and diverse picture emerges. Some broader tendencies can nevertheless be detected: there is increasing attention to the practice, language and psychology of mathematics, a move to reassess the orthodoxy, as well as inspiration from philosophical logic.

This article traces the limits of the understanding of beauty as unified multiplicity in Plotinus’ Enneads vi 2 and vi 6. These treatises can be read as insisting on the significance of multiplicity for beauty and as implying a distinction between the illuminated and the unilluminated beauty of Intellect. In treatise vi 7, this distinction is made explicit and a deeper understanding of beauty as the manifestation of the Good in Intellect is introduced.

This note is a continuation of our former paper ''Complexity of the r-query tautologies in the presence of a generic oracle.'' We give a very short direct proof of the nonexistence of t-generic oracles, a result obtained first by Dowd. We also reconstitute a proof of Dowd's result that the class of all r-generic oracles in his sense has Lebesgue measure one.

Although Plotinus’ two treatises on beauty could be taken to reflect an evolution in his thought, a careful examination shows that he consistently argues for a conception of beauty as the illuminated unity in multiplicity of the Intellect.

The author distinguishes two concepts of practical reason: (a) practical reason as a source of practical principles, and (b) practical reason as the theory of thought operations connected with action. He proves that there is no practical recognition in the sense (a). We can deal with actions only on the basis of dichotomic semantics. Critical analyses of some theories of practical reason are presented (Kant, Lorenzen, Apel, Alexy). The critical part of the paper mainly concerns the discourse theory and its (...) implications for practical philosophy and jurisprudence. (shrink)

The thesis investigates Plotinus' concept of beauty. Chapter 1 focuses on two methodological issues: development in Plotinus' thought and topics of the concerned Enneads. Since Plotinus wrote two Enneads directly devoted to this topic which were numbered and named by Porphyry I.6 On beauty and V.8 On intellectual beauty, these two treatises are addressed first in the context of other relevant Enneads. The outcome of these chapters is that beauty is primarily to be found in Intellect and that it is (...) closely linked with unity in multiplicity, so this topic is further investigated in more detail. Five mutually interconnected perspectives Plotinus assumes to describe the unity in multiplicity specific to the Intellect, are outlined. Two of them that are related to the nature of intellection and intelligible objects are discussed in chapters 2 and 3. The one related to Intellect's genesis is analysed throughout the thesis. Therefore, most of chapter 4 focuses on the remaining two perspectives which are connected with Intellect's hierarchical and structural unity in multiplicity. In chapter 5, Ennead VI.7 is analysed in order to deepen the concept of beauty and refine its relation to the Good, life and other predicates. The last chapter presents a systematic... (shrink)

The essay first succinctly points out shortcomings in previous interpretations of Plotinus’ notion of beauty. Beauty is to be connected primarily with Intellect, which is to be understood as a special unity in diversity. The section of the essay devoted to aesthetics is therefore preceded by a short analysis of Intellect’s unity and diversity. The hypothesis about the primary relation of beauty to the Intellect is then corroborated by a reading of Ennead V.8 and further developed. The emphasis is on (...) three basic aspects of beauty: its being a unity of a mixture whose character is shared by all ontological levels; its function of referring to what is above it; and its fundamental accessibility. Though Plotinus opposes the Stoic notion of beauty as symmetry and stresses beauty’s simplicity, it follows for him that beauty has the character of unitas multiplex, albeit a special one. (shrink)

This paper offers some ideas and methods of consensus building towards integration of values in flood control, environment, and landscape. These three factors sometimes oppose to each other in the process of construction of public infrastructure such as roadbuilding and river improvement. It is crucial to avoid or resolute conflicts between the government and the local people through project management with the consensus building process. In public works in Japan, flood control has been given priority over the environmental preservation and (...) the landscape conservation due to the perception that it is through flood control that the life and property of individuals are adequately protected. As a consequence, the landscape and the environment have been paid only lip‐service. In the case of the Ohashi River Project in Izumo region presented in this paper, however, the river repair process might entail a severe blow to the tourism industry and have a dramatic impact on the fishery resources of the region, which would be considered a major loss in terms of the urban development of the city. One of our concerns is thus to avoid any losses, through proper consideration of the relationship between the three crucial factors. In this paper, the author reports some ideas and methods that appear in “Basic Policy for the Development of the Area around Ohashi River” composed by the Matsue Review Committee on the Development of the Area around the Ohashi River, in which the author is involved as a committee member. The most important task of the Committee wasto search for the ideas and methods to harmonize the values of flood control, environment, and landscape. (shrink)

Alternative interpretations are proposed for the finding that market integration is positively related to fair behavior in experimental games. Market activities may produce market relevant concepts and stories that interpret experimental games as incidences of social exchange, and thus may enhance the relevance of (1) market-related preferences or (2) a decision heuristic designed for social exchange.

Pyridoxal 5′‐phosphate, the vitamin B6 derivative, acts as the coenzyme of many enzymes involved in amino acid metabolism. Exceptionally, this compound was found covalently bound to glycogen phosphorylase, the key enzyme in the regulation of glycogen metabolism. Although it is essential for the function of phosphorylase, its direct role has remained an enigma. We have recently found that the glucose moiety of pyridoxal (5′)diphospho (1)‐α‐D‐glucose, a conjugate of pyridoxal 5′‐phosphate and glucose 1‐phosphate through a pyrophosphate linkage, is transferred to the (...) nonreducing end of glycogen, forming a new α‐1,4‐glucosidic linkage. This finding emphasizes the importance of the direct phosphate‐phosphate interaction between the coenzyme and the substrate in the phosphorylase catalytic reaction. We have proposed a catalytic mechanism for phosphorylase in which the phosphate group of pyridoxal 5′‐phosphate acts as an electrophile to the phosphate group of glucose 1‐phosphate. This appears to represent the first instance of the direct involvement of a phosphate group in catalysis by enzymes. (shrink)

Feinberg and Mallatt, in their presentation of neurobiological naturalism, have suggested that visual consciousness was acquired by early vertebrates and inherited by a wide range of descendants, and that its neural basis has shifted to nonhomologous nervous structures during evolution. However, their evolutionary scenario of visual consciousness relies on the assumption that visual consciousness is closely linked with survival, which is not commonly accepted in current consciousness research. We suggest an alternative idea that visual consciousness is linked to a specific (...) class of agency, consequently justifying their phylogenetic claim. We also examine the implication of their phylogenetic claim: visual consciousness is homologous across vertebrates, but its neural basis is not. This apparent incongruence illustrates a general phenomenon of homology, and that the resulting hierarchical view of visual consciousness and its neural basis can be straightforwardly accommodated by neurobiological naturalism. Throughout these discussions, we aim to address the potential theoretical issues in neurobiological naturalism and refine the picture illustrated by Feinberg and Mallatt regarding phylogenetic distribution and trajectories of visual consciousness.

Modality - the question of what is possible and what is necessary - is a fundamental area of philosophy and philosophical research. The Routledge Handbook of Modality is an outstanding reference source to the key topics, problems and debates in this exciting subject and is the first collection of its kind. Comprising thirty-five chapters by a team of international contributors the Handbook is divided into seven clear parts: worlds and modality essentialism, ontological dependence, and modality modal anti-realism epistemology of modality (...) modality in science modality in logic and mathematics modality in the history of philosophy. Within these sections the central issues, debates and problems are examined, including possible worlds, essentialism, counterfactuals, ontological dependence, modal fictionalism, deflationism, the integration challenge, conceivability, a priori knowledge, laws of nature, natural kinds, and logical necessity. The Routledge Handbook of Modality is essential reading for students and researchers in epistemology, metaphysics and philosophy of language. It will also be very useful for those in related fields in philosophy such as philosophy of mathematics, logic and philosophy of science. (shrink)
