ABSTRACT The phenomenological vision, particularly, Husserl’s idea of critique as an infinite vocational theoria and Patočka’s as an enduring programme, view Platonic logic and Socratic act as the paradigms for a normative justification of the idea of universal science and philosophy. In light of that, the Thrasymachus-Socrates debate is interpreted as a case to testify the critical power of philosophy successfully exercised over sophistic tyrannical non-philosophy. This paper criticizes the phenomenological idealization of the Socratic victory as an ethico-teleologically anticipated success (...) of philosophy and rewrites the defeat of Thrasymachus as a political failure in warring with philosophy during which Thrasymachus questions the legitimacy of the act of philosophizing to decide its legitimacy and thereby exposes the politics played out in that act.

A decision tree is one of the machine learning techniques and also one of the major knowledge representations of data mining results.This is because it is easy to understand its meaning for human analysts.Even ID3, the representative algorithm, is known to exhibit remarkable performance deterioration under certain circumstances, particularly due to strong correlation between attributes representing the class of examples. One of the approaches to get more preferable decision trees is pre-processing the training data to extend its description, such as (...) attributes generation and attribute selection. There is also the idea of decision trees with a region rule. In this paper, we consider two approaches, i.e., decision trees with a region rule allowing multiple attributes, and a pre-processing method of a region rule to enabling any suitable number of attributes to correspond to branch nodes, where an optimal division condition with arbitrarily multiple attributes is acquired. By using this method, we propose a new decision tree generation algorithm guaranteeing to select effective compound attributes with each branch node, where an MDL-based new evaluation criterion is also defined for determining the optimal number of compound attributes specified to each node.This algorithm is applied to datasets containing only nominal values. It consists of three processes: compound attributes selection, parent node integration, and pruning. We call this new decision trees DTMACC (Decision Trees with Multiple Attributes Concept Clustering). The effectiveness and comprehensiveness of the proposed algorithm are confirmed through experiments comparing to the ordinary decision trees and an effective pre-processing method. (shrink)

The vestibulo-ocular reflex plays an important role in controlling the gaze at a visual target. Although patients with vestibular hypofunction aim to improve their VOR function, some retain dysfunction for a long time. Previous studies have explored the effects of direct current stimulation on vestibular function; however, the effects of random noise stimulation on eye–head coordination have not previously been tested. Therefore, we aimed to clarify the effects of high frequency noisy vestibular stimulation on eye–head coordination related to VOR function. (...) Thirteen healthy young adult participants with no serious disease took part in our study. The current amplitude and density used were 0.4 mA and 0.2 mA/cm2, respectively, with a random noise frequency of 100–640 Hz. The electrodes were located on both mastoid processes. The stimulus duration and fade in/out duration were 600 and 10 s, respectively. Subjects oscillated their head horizontally, gazing at the fixation point, at 1 Hz for 30 repetitions. The coordination of eye–head movements was measured by eye-tracking and a motion capture system. Peak-to-peak angles for eye and head movement and deviation of the visual line from the fixation target revealed no significant differences between HF-nVS and sham. The lag time between the eye and head movement with HF-nVS post-stimulation was significantly shorter than that of the sham. We found that HF-nVS can reduce the lag time between eye and head movement and improve coordination, contributing to a clear retinal image. This technique could be applied as a form of VOR training for patients with vestibular hypofunction. (shrink)

Miyagawa (Games and Economics Behavior 41(2), 292–308 [2002]) provides a simple extensive game form that implements a large class of two-agent bargaining solutions in subgame-perfect equilibrium. This class includes all of the Nash, Kalai–Smorodinsky, and relative utilitarian solutions. This note extends Miyagawa’s result to multi-agent bargaining problems.

Real-world walking activity is important for poststroke patients because it leads to their participation in the community and physical activity. Walking activity may be related to adaptability to different surface conditions of the ground. The purpose of this study was to clarify whether walking adaptability on an uneven surface by step is related to daily walking activity in patients after stroke. We involved 14 patients who had hemiparesis after stroke and 12 healthy controls. The poststroke patients were categorized as least (...) limited community ambulators or unlimited ambulators. For the uneven surface, the study used an artificial grass surface. The subjects repeated even surface walking and the uneven surface walking trials at least two times at a comfortable speed. We collected spatiotemporal and kinematic gait parameters on both the even and uneven surfaces using a three-dimensional motion analysis system. After we measured gait, the subjects wore an accelerometer around the waist for at least 4 days. We measured the number of steps per day using the accelerometer to evaluate walking activity. Differences in gait parameters between the even and uneven surfaces were calculated to determine how the subjects adapted to an uneven surface while walking. We examined the association between the difference in parameter measurements between the two surface properties and walking activity. Walking activity significantly and positively correlated with the difference in paretic step length under the conditions of different surface properties in the poststroke patients and step width in the healthy controls. The strategy of increasing the paretic step length, but not step width, on an uneven surface may lead to a larger base of support, which maintains stability during gait on an uneven surface in poststroke patients, resulting in an increased walking activity. Therefore, in poststroke patients, an increase in paretic step length during gait on an uneven surface might be more essential for improving walking activity. (shrink)

Employing conversation analysis, this article investigates instructions in lessons for guitar and Japanese calligraphy. In receiving an instruction, the students in the guitar lessons are expected to immediately follow the instruction. In contrast to the guitar lessons, the students in the calligraphy lessons are not institutionally expected to immediately follow the teacher’s instructions but to receive them. However, the students often gesticulate what they learned from and could make sense of the prior instruction upon completion of an instruction activity. I (...) call this phenomenon embodied solitary confirmation. By demonstrating the interactional procedure for this practice, this article respecifies reflection as an interactional phenomenon and elucidates an organization of multiactivity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Music Teacher Education in Japan:Structure, Problems, and PerspectivesMasafumi OgawaSchool music education in Japan is in a less than ideal situation. In April 2002, the new course of study was implemented by the Ministry of Education, Culture, Sports, Science and Technology (MEXT).1 The total number of music classes in the new curriculum was reduced to 33% of what it had been by the end of 2002. The reduction went from (...) two hours of music classes every week in grades one through nine to one hour in grades five through nine. This inevitably caused many problems. First, it became very difficult to teach music sequentially and instead music classes tended to be fragments of introductory experiences taught as disconnected activities. In this situation, it has been difficult for students to develop musical knowledge and skills. Second, the number of full-time music teachers was reduced greatly. It became common for a music teacher to teach at more than two schools in order to fill a full-time assignment. In some scenarios, many full-time music teachers were replaced with part-time teachers or teachers of other subjects. Music teachers have become disposable.Many music teachers are losing their effectiveness in the classroom. Students consider school music classes as a time to relax compared with other "intellectual subjects."2 They sometimes question music as an essential subject because they [End Page 139] do not value the developing skills that music requires or studying the theory of music. They believe that they can enjoy music outside of school anyway. Consequently, they are quite reluctant to participate in music classes and so behavioral problems arise and classroom management becomes more difficult. Some teachers attempt to force students to obey and force them to order; other teachers totally give up and let students behave as they like in class.3 In either case, teachers and students do not relate well to each other. It is not an exaggeration to say that school music in Japan is at risk of collapsing altogether and disappearing from the curriculum.One of the reasons for this, I believe, is that we have not wrestled with the fundamental problems of school music education until today. We might have intentionally avoided reviewing and criticizing the curriculum, expectations, and purposes of music education because it has been taboo to discuss the national standards, particularly for public school teachers to do so. Social and environmental conditions have changed greatly since the current system of Japanese education was established in 1947. It is obvious that the existing system does not match the new conditions.I strongly feel that it is time to review and reexamine what our pioneers of music education and the government had achieved in the field of music education. If we continue to avoid doing so, music in the schools will face serious consequences. In this paper, I discuss some of the fundamental issues of music teacher education in Japan. There are two reasons for focusing on music teacher education. First, starting with music teacher education is most important because music teachers have the most significant roles in school music education. Second, I have been engaged in music teacher education for seventeen years, and this is not only my research area but also an area in which, as an insider, I can offer direct insights. I will limit this essay to looking at the preparation of teachers in music for elementary and middle schools (grades 7 to 9).StructureThe course of study (COS) is a set of national curriculum standards for kindergarten, elementary, middle, and high school, and schools for the handicapped and is issued by the MEXT.4 All schools, public or private, are required to follow these standards. No other curriculum is allowed. Therefore, in Japan, the COS is law through which the government controls all educational actions. The COS was first issued in 1947 and has been revised seven times.5 The most recent revision was announced in December 1998 for kindergarten, elementary, and middle schools, and in March 1999 for the other levels. All schools in Japan were required to implement the revised COS by April 2002. [End Page 140]The COS of... (shrink)

Categorial grammar is well-known for its elegant analysis of coordination enabled by the flexible notion of constituency it entertains. However, to date, no systematic study exists that examines whether this analysis has any obvious empirical advantage over alternative analyses of nonconstituent coordination available in phrase structure-based theories of syntax. This paper attempts precisely such a comparison. We compare the direct constituent coordination analysis of non-canonical coordinations in categorial grammar with an ellipsis-based analysis of the same phenomena in the recent HPSG (...) literature. We provide a set of empirical evidence, consisting of cases in which non-canonical coordinations interact with scopal operators of various sorts, which systematically falsifies the predictions of the latter, ‘linearization-based’ ellipsis approach to coordination. We propose an alternative analysis in a variant of categorial grammar called Hybrid Type-Logical Categorial Grammar. The proposed framework builds on both the Lambek-inspired variants of categorial grammar and a more recent line of work modelling word order via a lambda calculus for the prosodic component. The flexible syntax–semantics interface of this framework straightforwardly captures the interactions between non-canonical coordinations and scopal expressions, demonstrating the broader empirical payoff of the direct constituent coordination analysis of non-canonical coordinations pioneered by Steedman :523–568, 1985; Linguist Philos 13:207–263, 1990) and Dowty hitherto not explicitly recognized in the literature.

Young children generally learn words from other people. Recent research has shown that children can learn new actions and skills from nonhuman agents. This study examines whether young children could learn words from a robot. Preschool children were shown a video in which either a woman or a mechanical robot labeled novel objects. Then the children were asked to select the objects according to the names used in the video. The results revealed that children in the human condition were more (...) likely to select the correct objects than those in the robot condition. Nevertheless, the five-year-old children in the robot condition performed significantly better than chance level, while the four-year olds did not. Thus there is a developmental difference in children’s potential to learn words from a robot. The results contribute to our understanding of how children interact with non-human agents. Keywords: developmental cybernetics; word learning; social cognition; cognitive development. (shrink)

The concept and the logic of the political, the most notable Schmittian ideas, based on the friend/enemy distinction and his thought on political theology have been widely and critically discussed and actively appropriated with various interpretations. On the other hand, we find that there is certain definite momentum piercing through the theoretical structure of Husserl’s phenomenology in general both as a form of metaphysics and as a philosophical movement, which can also be called the political. In this circumstance, we find (...) the Schmittian logic of the political together with his idea of political theology specifically serviceable for an effective visualization of the political characteristically structured in Husserl’s system, particularly in the concepts of transcendental subjectivity and universal critique. This paper argues that Husserl’s phenomenological critical subject is fundamentally a politico-theological subject and is an attempt to show to what extent and in what way Schmitt can be strategically utilized to make manifest the politicality that we discover as something that structurally inheres in Husserlian notion of subjectivity and critique. *.

This essay retrieves the meaning and importance of renga, or linking poetry. Long forgotten, even in Japan, it was the form of which the great Bashō was the mater (not haiku as is now believed). When examining renga poetry, one can see that it is based not on authorial vision, but rather the trans-subjective mood that guides the different links made by the various poets who collaborate in the “rolling” of a renga. The radical implications of this form for both (...) aesthetics and ethics will be considered. (shrink)

Husserl’s phenomenology opens itself with a critique of positive sciences. Husserl problematizes the hardcore presupposition of positivism that the world is a definite sort of an existential totality of objects and thus it is exhaustible with empirical data and deductive-conceptual abstraction on the basis of causalspatio-temoprality. Criticizing the wholesome reduction of nature into a physical reality and the instrumentalizing of theoretical reason, he proposes transcendental phenomenology, as an ideal form of science. Self-entitled as the genuine science, the science of origin, (...) the science of all sciences, etc., it concerns itself with the matter of validity. Claiming that validating objectivity as such and the meaning of scientific objectification is something of which onlyphenomenological reflection on pure consciousness is capable and that the positivistic objectivity is and must be founded on transcendental subjectivity, Husserl radically idealistically revised the whole positivistic concept of evidence and givenness of a fact and substituted it with the phenomenological notion of apriori self-evidence and originary givenness of primordial intentional consciousness. Nevertheless, it is noticed that the absolute universal validity of positivistic objectivity was never rejected or questioned; objectivity is still in and of itself an absolute criterion of scientificity in Husserl. This paper will argue that the idealistic turn toward subjectivity takes place through factualization of transcendentality and this, by bestowing apriori apodicticity with facticity, even enhances more the supreme epistemological function of positivity. It will discuss such positivistic drive, directly bequeathed from the very cultural ethos at which phenomenological criticism targeted, as an important locomotive for Husserl’s program and point out an antinomical consequence with which it is to be faced as a consequence.

This study aims to explicate interviewer and candidate conversational practices in L2 job interviews as they relate to the assessment of a candidate’s qualification for a particular position. The data consisted of 27 audio-recorded job interviews for the position of student assistant in English classes at a Japanese university. The analysis of these interactional data, conducted using conversational analysis methodology, revealed that the inadequacy of a candidate’s response is constructed by means of the interviewer’s subsequent pursuit of a relevant answer (...) from the candidate. In addition, a candidate’s ability to build rapport by providing sequentially linked joke-serious responses evoked a positive evaluation from the interviewer. The findings indicate that a candidate’s understanding of expected behaviors and ability to accommodate his or her behaviors in a manner relevant to the interaction result in a positive assessment.

Previous studies have suggested that musical training in childhood is beneficial for sociability. However, it remains unclear how age of onset of group music lessons is associated with the late sociability of children from a long-term perspective. This study investigated associations between group music lessons conducted at a music school and children’s levels of sociability by focusing on the age of onset of the lessons. We conducted a survey of 276 children aged 4–5 years (M = 58.5 months) and 6–7 (...) years (M = 82.7 months) who commenced music lessons at ages 1, 2, 4, and 6 years. We found that (1) the empathy scores of children aged 6–7 years who began lessons when 1-year-old were greater than those who began lessons when 4-years-old, (2) the communication scores of children aged 4–5 years who began lessons when 1-year-old were greater than those who began lessons when older than 1 year, and (3) the empathy and extraversion scores were high in those aged 6–7 years who began lessons in that age range. The results suggest that early onset of music lessons could positively influence children’s sociability; in contrast, after about age 7 years, children who already had high sociability may be more inclined to select group music lessons. By focusing on the impact of regular group music lessons from a very young age on later levels of sociability, these results further elucidate the effects of musical lessons. In sum, participation in group music lessons 2–4 times per month can be effective social training for very young children and foster their later sociability. (shrink)

During brain development, neural precursor cells (NPCs) in different brain regions produce different types of neurons, and each of these regions plays a different role in the adult brain. Therefore, precise regionalization is essential in the early stages of brain development, and irregular regionalization has been proposed as the cause of neurodevelopmental disorders. The mechanisms underlying brain regionalization have been well studied in terms of morphogen‐induced expression of critical transcription factors for regionalization. NPC potential in different brain regions is defined (...) by chromatin structures that regulate the plasticity of gene expression. Herein, we present recent findings on the importance of chromatin structure in brain regionalization, particularly with respect to its regulation by Polycomb‐group proteins and chromatin accessibility.

The aim of this paper is to call the attention, especially that of feminists, to the current progress in biology. It appears gender studies still confine themselves to outdated ideas of sex chromosomes like XX, XY (§10). However, science has been making progress. It no longer sticks to such matters as XX, XY. Its interest is now in Sry, a kind of gene (§11), and MIS, a kind of sex hormone (§14). Abnormalities of sex chromosomes are no longer evidence to (...) deny the biological approaches, for example. We shed light on this fact, putting gender studies in the context of chronologies of science as well (§§2-9). (shrink)

The aim of this paper is to apply inductive logic to the field that, presumably, Carnap never expected: legal causation. Legal causation is expressible in the form of singular causal statements; but it is distinguished from the customary concept of scientific causation, because it is subjective. We try to express this subjectivity within the system of inductive logic. Further, by semantic complement, we compensate a defect found in our application, to be concrete, the impossibility of two-place predicates (for causal relationship) (...) in inductive logic.

Although we often see references to Carnap’s inductive logic even in modern literatures, seemingly its confusing style has long obstructed its correct understanding. So instead of Carnap, in this paper, I devote myself to its necessary and sufficient commentary. In the beginning part (Sections 2-5), I explain why Carnap began the study of inductive logic and how he related it with our thought on probability (Sections 2-4). Therein, I trace Carnap’s thought back to Wittgenstein’s Tractatus as well (Section 5). In (...) the succeeding sections, I attempt the simplest exhibition of Carnap’s earlier system, where his original thought was thoroughly provided. For this purpose, minor concepts to which researchers have not paid attention are highlighted, for example, m-function (Section 8), in-correlation (Section 10), C-correlate (Section 10), statistical distribution (Section 12), and fitting sequence (Section 17). The climax of this paper is the proof of theorem (56). Through this theorem, we will be able to overview Carnap’s whole system. (shrink)

The original interest of this article lies in existential import. It provides a broader view on the problem by reference to modern, symbolic logic (ch.1). Gradually, however, our interest will change into the amalgamated expressions often used in logic; that is, why are such expressions as “x is a round triangle” applied in logic? We critically discuss this question from an extensional viewpoint, namely model theoretic semantics (ch.2). We also touch on Church’s λ-calculus in the appendix (app.2).
