In this paper, illocutionary acts of commanding will be differentiated from perlocutionary acts that affect preferences of addressees in a new dynamic logic which combines the preference upgrade introduced in DEUL (dynamic epistemic upgrade logic) by van Benthem and Liu with the deontic update introduced in ECL II (eliminative command logic II) by Yamada. The resulting logic will incorporate J. L. Austin’s distinction between illocutionary acts as acts having mere conventional effects and perlocutionary acts as acts having real effects (...) upon attitudes and actions of agents, and help us understand why saying so can make it so in explicit performative utterances. We will also discuss how acts of commanding give rise to so-called “deontic dilemmas” and how we can accommodate most deontic dilemmas without triggering so-called “deontic explosion”. (shrink)

Crispin Wright in his 1982 paper argues for strict finitism, a constructive standpoint that is more restrictive than intuitionism. In its appendix, he proposes models of strict finitistic arithmetic. They are tree-like structures, formed in his strict finitistic metatheory, of equations between numerals on which concrete arithmetical sentences are evaluated. As a first step towards classical formalisation of strict finitism, we propose their counterparts in the classical metatheory with one additional assumption, and then extract the propositional part of ‘strict finitistic (...) logic’ from it and investigate. We will provide a sound and complete pair of a Kripke-style semantics and a sequent calculus, and compare with other logics. The logic lacks the law of excluded middle and Modus Ponens and is weaker than classical logic, but stronger than any proper intermediate logics in terms of theoremhood. In fact, all the other well-known classical theorems are found to be theorems. Finally, we will make an observation that models of this semantics can be seen as nodes of an intuitionistic model.

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.4 (2003) 50-58 [Access article in PDF] Evolution in Qualitative Factors Used to Evaluate Japanese Students [Tables] Introduction Two basic viewpoints are typically taken in the evaluation of achievement in Japanese schools: either the focus is primarily on "field-content-basedevaluation" or on "ability-concept-based evaluation." I have compared the qualitative factors encompassed by these two viewpoints as reflected in the permanent school records of Japanese students. (...) These recordsinclude classes taken, grades earned, and school-related information. Kanten (in Japanese) has become a key word in the evaluation of academic achievement in Japan. It represents the qualitative factors that should be considered when evaluating a student's learning achievements. In this essay, I review how these qualitative factors have evolved, both for general subjects and for fine arts.From the beginning of the educational system (1872) to 1938, the "assessment" [Hyoutei] of a student depended on the comprehensiveness of the student's achievement in each subject. (Overall assessments are now usually made using a three-point scale; 1-3, a five-point scale; 1-5, or an ABC scale.) However, it was not clearly specified how scholastic ability and learning accomplishment should be assessed or which qualitative factors should be considered.Starting in 1941, teachers were required to evaluate, comprehensively assess, and record the student's learning, consideration, dealing, application, skill, appreciation, practice, and learning attitude through his or her daily learning and activity. 1 The factors seem to be basically equivalent to those recently used as "interest/aspiration/attitude," "thinking," "judgment," [End Page 50] and "expressive power." After 1941, the point of view in the area of fine arts gradually changed from focusing on the "field-content-based factor" to the "ability-concept-based factor" in both the educational content and in evaluation.This report focuses on the evolution in the qualitative factors used in evaluations in the postwar era. From 1949 to 1991 "Understanding," "attitude," and "skill" were specified as factors that shouldbe considered when evaluating a student's learning achievements in 1949. For a few years, these factors were considered independently in the non-referenced evaluation of five-point ratings. The two basic viewpoints, "field-content-based factor" and "ability-concept-based factor," coexisted in the course of study in the early 1950s, according to a tentative plan published in 1951. "Attitude" and "habits" carried the same weight as "understanding" and "skill." These factors received minimal attention at the elementary school level. Evaluations thus evolved from simply an overall assessment of the student's achievement in a subject to an assessment of these specific factors. For instance, at the elementary school level, drawing and handicrafts both had factors related to "field content difference" (for example, drawing, color, and pattern) and to "ability concept difference" (for example, attitude and habit). At the junior high level, the factors were represented by a double-layer structure (Table 1). The elements underlined in Table 1 reflect on the "ability concept difference" (for example, expression activities and understanding activities) instead on the "field content difference." Following the revision of the permanent cumulative records in 1955, students were evaluated based only on an overall assessment of their individual [End Page 51] performance in each subject (Japanese language, mathematics, social studies, music, and drawing and handicrafts). There were three main reasons for this change.The effort it takes to evaluate each factor analytically. The difficulty of evaluating "attitude." The demand by schools at the next level for a comprehensive and uniform evaluation for each student for each subject. 3Furthermore, although "interest" was added as one of factors to be considered in the evaluation, it was not to be dealt with analytically in the evaluation of what the student learned. Consequently, evaluations became clearer and more comprehensive, although the weights of the factors, referred to as the "affective domain," took a step backward. In 1961, the factor "interest/attitude toward fine arts" was added. At the same time, "interest" was given more weight. However, the higher weighting of the factor was short-lived because intangible factors such as... (shrink)

There are three main points of the paper. 1. There are straightforward ways of manipulating expected gains and losses that result in a divergence between fair betting odds and credence. Such manipulations are familiar from tools of finance. One can easily see that the Sleeping Beauty case is structured in such a way as to result in a divergence between fair betting odds and credence. 2. The inspection of credences and betting odds in certain betting situations shows that the two (...) main extant positions, Elga's and Lewis's, are both mistaken. 3. My proposal may seem to require a revision of probability theory but it does not. The Sleeping Beauty case merely calls attention to a constraint on partitioning of possibility space that is usually satisfied as a matter of course but can in fact be violated. (shrink)

If the notion of speech acts is to be taken seriously, it must be possible to treat speech acts as acts. The development of systems of DEL (dynamic epistemic logic) in the last two decades suggests an interesting possibility. These systems are developed on the basis of static epistemic logics by introducing model updating operations to interpret various kinds of speech acts including public announcements as well as private information transmissions as what update epistemic states of agents involved. The methods (...) used in developing DEL can be used to develop logics that deal with a much wider variety of speech acts. For example, in ECL (Eliminative Command Logic) of Yamada (2007a) and ECL II of Yamada (2007b), similar model updating operations are introduced tointerpret acts of commanding as what update deontic aspects of the situations in which agents are involved. In Yamada (2008a), ECL II is further extended so as to model acts of promising along with acts of commanding. Moreover, in Yamada (2008b), ECL II is combined with a modified version of DEUL (dynamic epistemic upgrade logic) introduced in van Benthem & Liu (2007). In the resulting logic DDPL (dynamic deontic preference logic), illocutionary acts of commanding are differentiated from preference upgrading perlocutionary acts. The development of these logics suggests a recipe for developing logics that deal with various specific speech acts: first, carefully identify the aspects affected by the speech acts you want to study; second, find the modal logic that characterizes the aspects in question; and finally, add dynamic modalities that stand for the types of the speech acts being studied and define model updating operation that interprets these speech acts as what update the very aspects.

One prominent feature of belief is that a belief cannot be formed at will. This paper argues that the best explanation of this fact is that belief formation is a process that takes aim at the truth. Taking aim at the truth is to be understood as causal responsiveness of the processes constituting belief formation to what facilitates achieving true beliefs. The requirement for this responsiveness precludes the possibility of belief formation responding to intentions in a way that would count (...) as forming a belief at will. (shrink)

This paper presents the first dataset for Japanese Legal Judgment Prediction (LJP), the Japanese Tort-case Dataset (JTD), which features two tasks: tort prediction and its rationale extraction. The rationale extraction task identifies the court’s accepting arguments from alleged arguments by plaintiffs and defendants, which is a novel task in the field. JTD is constructed based on annotated 3477 Japanese Civil Code judgments by 41 legal experts, resulting in 7978 instances with 59,697 of their alleged arguments from the involved parties. Our (...) baseline experiments show the feasibility of the proposed two tasks, and our error analysis by legal experts identifies sources of errors and suggests future directions of the LJP research.

Developmental research suggests that young children tend to value dominant individuals over subordinates. This research, however, has nearly exclusively been carried out in Western cultures, and cross-cultural research among adults has revealed cultural differences in the valuing of dominance. In particular, it seems that Japanese culture, relative to many Western cultures, values dominance less. We conducted two experiments to test whether this difference would be observed in preschoolers. In Experiment 1, preschoolers in France and in Japan were asked to identify (...) with either a dominant or a subordinate. French preschoolers identified with the dominant, but Japanese preschoolers were at chance. Experiment 2 revealed that Japanese preschoolers were more likely to believe a subordinate than a dominant individual, both compared to chance and compared to previous findings among French preschoolers. The convergent results from both experiments thus reveal an early emerging cross-cultural difference in the valuing of dominance. (shrink)

This paper describes an automatic monitoring system that constantly checks partial update in Web pages and notifies them to a user. While one of the most important advantages of the WWW is update of Web pages, we need to constantly check them out and this task takes much cognitive load. Thus applications to automatically check update of Web pages have been developed, however they can not deal with partial update like update in a particular cell in a table in a (...) Web page. Hence we developed a automatic monitoring system that checks such partial update. A user can give a system regions in which he/she wants to know the update in a Web page as training examples, and it is able to learn rules to identify the partial update by classification learning. By this learning, a user do not need to directly describe the rules. We implemented our system and some executed examples were presented. (shrink)

In this paper, we develop an organization method of page information agents for adaptive interface between a user and a Web search engine. Though a Web search engine indicates a hit list of Web pages to user’s query using a large database, they includes many useless ones. Thus a user has to select useful Web pages from them with page information indicated on the hit list, and actually fetch the Web page for investigating the relevance. Unfortunately, since the page information (...) on a hit list is neither sufficient nor necessary for a user, the adequate information is necessary for valid selection. However which information is adequate depends on a user and a task. Hence we propose adaptive interface AOAI in which different page information agents are organized through man-machine interaction. In AOAI, the page information agents indicating different page information on a hit list like the file-size, network traffic and a page title are prepared at first. A user evaluates them through searching with a search engine, and the agents are organized based on the evaluation. As results, different organizations are achieved depending on a user and a task. Finally we make experiments with subjects and find out AOAI is promising for adaptive interface between a user and a search engine. (shrink)

Occupational therapy often uses craft activities as therapeutic tools, but their therapeutic effectiveness has not yet been adequately demonstrated. The aim of this study was to examine changes in frontal midline theta rhythm and autonomic nervous responses during craft activities, and to explore the physiological mechanisms underlying the therapeutic effectiveness of occupational therapy. To achieve this, we employed a simple craft activity as a task to induce Fmθ and performed simultaneous EEG and ECG recordings. For participants in which Fmθ activities (...) were provoked, parasympathetic and sympathetic activities were evaluated during the appearance of Fmθ and rest periods using the Lorenz plot analysis. Both parasympathetic and sympathetic indices increased with the appearance of Fmθ compared to during resting periods. This suggests that a relaxed-concentration state is achieved by concentrating on craft activities. Furthermore, the appearance of Fmθ positively correlated with parasympathetic activity, and theta band activity in the frontal area were associated with sympathetic activity. This suggests that there is a close relationship between cardiac autonomic function and Fmθ activity. (shrink)

Prior's three-valued modal logic Q was developed as a philosophically interesting modal logic. Thus, we should be able to modify Q as a temporal logic. Although a temporal version of Q was suggested by Prior, the subject has not been fully explored in the literature. In this paper, we develop a three-valued temporal logic $Q_t $ and give its axiomatization and semantics. We also argue that $Q_t $ provides a smooth solution to the problem of future contingents.

This paper presents what the authors call the ‘divergence problem’ regarding choosing between different future possibilities. As is discussed in the first half, the central issue of the problem is the difficulty of temporally locating the ‘active cause’ on the modal divergent diagram. In the second half of this paper, we discuss the ‘second-person freedom’ which is, strictly, neither compatibilist negative freedom nor incompatibilist positive freedom. The divergence problem leads us to two hypothetical views (i.e. the view of single-line determination (...) and that of one-off chance), and these views bring humans closer to the afree side – i.e. outside of the contrast between being free and being unfree. The afree side is greatly different from the ordinary human side. This paper tries to secure the second-person freedom as a substitute for the ordinary human freedom while preventing the divergence problem from arising. (shrink)

Anthropomorphic agents used in online-shopping need to be trusted by users so that users feel comfortable buying products. In this paper, we propose a model for designing trustworthy agents by assuming two factors of trust, that is, emotion and knowledgeableness perceived. Our hypothesis is that when a user feels happy and perceives an agent as being highly knowledgeable, a high level of trust results between the user and agent. We conducted four experiments with participants to verify this hypothesis by preparing (...) transition operators utilizing emotional contagion and knowledgeable utterances. As a result, we verified that users' internal states transitioned as expected and that the two factors significantly influenced their trust states. (shrink)

The purpose of the present study was two-fold. First we examined whether visible motion appearance was altered by the spatial interaction between invisible and visible motion. We addressed this issue by means of simultaneous motion contrast, in which a horizontal test grating with a counterphase luminance modulation was seen to have the opposite motion direction to a peripheral inducer grating with unidirectional upward or downward motion. Using a mirror stereoscope, observers viewed the inducer and test gratings with one eye, and (...) continuous flashes of colorful squares forming an annulus shape with the other eye. The continuous flashes rendered the inducer subjectively invisible. The observers’ task was to report whether the test grating moved upward or downward. Consequently, simultaneous motion contrast was observed even when the inducer was invisible . Second, we examined whether the observers could correctly respond to the direction of invisible motion: It was impossible. (shrink)
