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.

We present an annotation scheme describing the argument structure of judgement documents, a central construct in Japanese law. To support the final goal of this work, namely summarisation aimed at the legal professions, we have designed blueprint models of summaries of various granularities, and our annotation model in turn is fitted around the information needed for the summaries. In this paper we report results of a manual annotation study, showing that the annotation is stable. The annotated corpus we created contains (...) 89 documents. We also designed and implemented the first two stages of an algorithm for the automatic extraction of argument structure, and present evaluation results. (shrink)

In his “A new argument for evidentialism” (Shah, Philos Q 56(225): 481–498, 2006 ), Nishi Shah argues that the best explanation of a feature of deliberation whether to believe that p which he calls transparency entails that only evidence can be reason to believe that p. I show that his argument fails because a crucial lemma that his argument appeals to cannot be supported without assuming evidentialism to be true in the first place.

A classical reconstruction of Wright’s first-order logic of strict finitism is presented. Strict finitism is a constructive standpoint of mathematics that is more restrictive than intuitionism. Wright sketched the semantics of said logic in Wright (Realism, Meaning and Truth, chap 4, 2nd edition in 1993. Blackwell Publishers, Oxford, Cambridge, pp.107–75, 1982), in his strict finitistic metatheory. Yamada (J Philos Log. https://doi.org/10.1007/s10992-022-09698-w, 2023) proposed, as its classical reconstruction, a propositional logic of strict finitism under an auxiliary condition that makes the (...) logic correspond with intuitionistic propositional logic. In this paper, we extend the propositional logic to a first-order logic that does not assume the condition. We will provide a sound and complete pair of a Kripke-style semantics and a natural deduction system, and show that if the condition is imposed, then the logic exhibits natural extensions of Yamada (2023)’s results.

This paper considers fair betting odds for certain bets that might be placed in the situation discussed in the so-called Sleeping Beauty Problem. This paper examines what Thirders, Halfers, and Double Halfers must say about the odds as determined by various decision theoretic approaches and argues that Thirders and Halfers have difficulties formulating plausible and coherent positions concerning the relevant betting odds. Double Halfers do not face this problem and that is an important consideration in favor of Double Halfers.

Approximately one in two hundred persons in the Marshall Islands have active tuberculosis. We examine the historical antecedents of this situation in order to assign ethical responsibility for the present situation. Examining the antecedents in terms of Galtung’s dialectic of personal versus structural violence, we can identify instances in the history of the Marshall Islands when individual subjects made decisions with large-scale ecologic, social, and health consequences. The roles of medical experimenters, military commanders, captains of the weapons industry in particular, (...) and industrial capitalism in general are examined. In that, together with Lewontin, we also identify industrial capitalism as the cause of tuberculosis, we note that the distinction between personal versus structural violence is difficult to maintain. By identifying the cause of the tuberculosis in the Marshall Islands, we also identify what needs be done to treat and prevent it. (shrink)

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)

Although it seems intuitively clear that acts of requesting are different from acts of commanding, it is not very easy to sate their differences precisely in dynamic terms. In this paper we show that it becomes possible to characterize, at least partially, the effects of acts of requesting and compare them with the effects of acts of commanding by combining dynamified deontic logic with epistemic logic. One interesting result is the following: each act of requesting is appropriately differentiated from an (...) act of commanding with the same content, but for each act of requesting, there is another act of commanding with much more complex content which updates models in exactly the same way as it does. We will also consider an application of our characterization of acts of requesting to acts of asking yes-no questions. It yields a straightforward formalization of the view of acts of asking questions as requests for information. (shrink)

Emotion modulates our time perception. So far, the relationship between emotion and time perception has been examined with visible emotional stimuli. The present study investigated whether invisible emotional stimuli affected time perception. Using continuous flash suppression, which is a kind of dynamic interocular masking, supra-threshold emotional pictures were masked or unmasked depending on whether the retinal position of continuous flashes on one eye was consistent with that of the pictures on the other eye. Observers were asked to reproduce the perceived (...) duration of a frame stimulus that was concurrently presented with a masked or unmasked emotional picture. As a result, negative emotional stimuli elongated the perceived duration of the frame stimulus in comparison with positive and neutral emotional stimuli, regardless of the visibility of emotional pictures. These results suggest that negative emotion unconsciously accelerates an internal clock, altering time perception. (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.

Backgrounds: Transcranial direct current stimulation is a non-invasive brain stimulation technique for the treatment of several psychiatric disorders, e.g., mood disorders and schizophrenia. Therapeutic effects of tDCS are suggested to be produced by bi-directional changes in cortical activities, i.e., increased/decreased cortical excitability via anodal/cathodal stimulation. Although tDCS provides a promising approach for the treatment of psychiatric disorders, its neurobiological mechanisms remain to be explored.Objectives: To review recent findings from neurophysiological, chemical, and brain-network studies, and consider how tDCS ameliorates psychiatric conditions.Findings: (...) Enhancement of excitatory synaptic transmissions through anodal tDCS stimulation is likely to facilitate glutamate transmission and suppress gamma-aminobutyric acid transmission in the cortex. On the other hand, it positively or negatively modulates the activities of dopamine, serotonin, and acetylcholine transmissions in the central nervous system. These neural events by tDCS may change the balance between excitatory and inhibitory inputs. Specifically, multi-session tDCS is thought to promote/regulate information processing efficiency in the cerebral cortical circuit, which induces long-term potentiation by synthesizing various proteins.Conclusions: This review will help understand putative mechanisms underlying the clinical benefits of tDCS from the perspective of neurotransmitters, network dynamics, intracellular events, and related modalities of the brain function.

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)

BackgroundSocial cognitive impairments adversely affect social functioning in patients with schizophrenia. Although pharmacological interventions have been suggested to provide some benefits on social cognition, little information is available on the comparative efficacy of pharmacotherapy. Thus, the aim of this planned systematic review and network meta-analysis is to perform a quantitative comparison of the effects of various psychotropic drugs, including supplements, on social cognition disturbances of schizophrenia.MethodsThe literature search will be carried out using the PubMed, Embase, Cochrane Central Register of Controlled (...) Trials, PsycINFO, ClinicalTrials.gov, and International Clinical Trials Registry Platform databases from inception onward. Randomized controlled trials that examined the efficacy of drugs in social cognitive disturbances will be included, based on the most recent studies and the broader literature than previously searched. This protocol defines a priori the methods that will be used for study selection, data collection, quality assessment, and statistical syntheses.DiscussionThe findings this work are expected to help promote the development of better therapeutics of social cognitive impairments in schizophrenia and related psychiatric conditions.Systematic Review Registration[www.crd.york.ac.uk/prospero], identifier [CRD42021293224].

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.

The Manifestation Requirement, advanced by Dummett in his critique of semantic realism, has been criticized for being behavioristic, and the responses have been made that the critics are mistaken. However, the dispute has failed to exhibit the point of the Requirement. In this paper, I shall argue (1) that, in the light of Anscombe's theory of practical knowledge, knowledge of linguistic meaning is to be seen as the knowledge-how that forms the basis of the practical knowledge that an agent has (...) of his own intentional actions, (2) that such knowledge of linguistic meaning is to be based on mutual agreements in a community, and (3) that the Manifestation Requirement is a condition for the possibility of such mutual agreements. As a result, the Manifestation Requirement finds its basis on the idea that language and linguistic acts are tools that we use while continually improving them. (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)

In 1932, Japanese psychologist Takano Kiyoshi conducted experimental research on vibratory sensations using hundreds of deaf schoolchildren as research subjects. This article examines the little-studied relationship between the global spread of oralism and the local formulation of knowledge about the vibratory sense—or senkaku 顫覚—in Japanese psychoacoustics. In the 1920s, American missionaries and educators helped spread oralism in Japan, and the Japanese state implemented the Blind and Deaf-Mute Schools Ordinance. There was also a notable development of experimental psychology in the country. (...) Influenced by German psychologist David Katz’s work, Takano viewed deafness as a physical “ability” or physiological “advantage” for his scientific project. A close reading of Japanese, German, and American psychologists’ works on the vibratory sense around the time reveals that it was considered not quite identical to hearing, nor to touch. The five senses framework—based on the ideas of touch, hearing, sight, smell, and taste—does not always function properly in sensory history; this prevalent framework can put aside the actual nuances and complexities of one’s varying understanding of the human sensorium across time and space. This study highlights the (anonymous) participation of deaf individuals as research subjects and draws attention to how people with impairments played diverse roles in the history of science.

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)
