We treat a class of multi-person bargaining mechanisms based on games in coalitional form. For this class of games we identify properties of non-cooperative solution concepts, which are necessary and sufficient for the equilibrium outcomes to coincide with the core of the underlying coalitional form game. We view this result as a non-cooperative axiomatization of the core. In contrast to most of the literature on multi-person bargaining we avoid a precise specification of the rules of the game. Alternatively, we impose (...) properties of such games, which give rise to a large class of mechanisms, all of which are relevant for our axiomatization. (shrink)

The pervasive use of distributional semantic models or word embeddings for both cognitive modeling and practical application is because of their remarkable ability to represent the meanings of words. However, relatively little effort has been made to explore what types of information are encoded in distributional word vectors. Knowing the internal knowledge embedded in word vectors is important for cognitive modeling using distributional semantic models. Therefore, in this paper, we attempt to identify the knowledge encoded in word vectors by conducting (...) a computational experiment using Binder et al.'s (2016) featural conceptual representations based on neurobiologically motivated attributes. In an experiment, these conceptual vectors are predicted from text‐based word vectors using a neural network and linear transformation, and prediction performance is compared among various types of information. The analysis demonstrates that abstract information is generally predicted more accurately by word vectors than perceptual and spatiotemporal information, and specifically, the prediction accuracy of cognitive and social information is higher. Emotional information is also found to be successfully predicted for abstract words. These results indicate that language can be a major source of knowledge about abstract attributes, and they support the recent view that emphasizes the importance of language for abstract concepts. Furthermore, we show that word vectors can capture some types of perceptual and spatiotemporal information about concrete concepts and some relevant word categories. This suggests that language statistics can encode more perceptual knowledge than often expected. (shrink)

The two competing camps of theorists in moral psychology share one common view on the disagreement between their theories: moral foundations theory presupposes basic emotion theory, while dyadic morality theory presupposes constructionist theory of emotion. The paper challenges this common view. First, it reviews the four theories. Second, it clarifies the issue about the relation between the moral contents and emotions on which the two camps of moral-psychological theorists dispute. Third, it identifies the explananda for the moral-psychological theories, and examines (...) the two distinctive types of explanations that each of the two theories offers to them. Finally, it concludes that the deepest disagreement between the two morality theories consists in the role that the theories give to emotions in explaining moral judgments. (shrink)

Recent metaphor research has revealed that metaphor comprehension involves both categorization and comparison processes. This finding has triggered the following central question: Which property determines the choice between these two processes for metaphor comprehension? Three competing views have been proposed to answer this question: the conventionality view (Bowdle & Gentner, 2005), aptness view (Glucksberg & Haught, 2006b), and interpretive diversity view (Utsumi, 2007); these views, respectively, argue that vehicle conventionality, metaphor aptness, and interpretive diversity determine the choice between the categorization (...) and comparison processes. This article attempts to answer the question regarding which views are plausible by using cognitive modeling and computer simulation based on a semantic space model. In the simulation experiment, categorization and comparison processes are modeled in a semantic space constructed by latent semantic analysis. These two models receive word vectors for the constituent words of a metaphor and compute a vector for the metaphorical meaning. The resulting vectors can be evaluated according to the degree to which they mimic the human interpretation of the same metaphor; the maximum likelihood estimation determines which of the two models better explains the human interpretation. The result of the model selection is then predicted by three metaphor properties (i.e., vehicle conventionality, aptness, and interpretive diversity) to test the three views. The simulation experiment for Japanese metaphors demonstrates that both interpretive diversity and vehicle conventionality affect the choice between the two processes. On the other hand, it is found that metaphor aptness does not affect this choice. This result can be treated as computational evidence supporting the interpretive diversity and conventionality views.

The paper traces the development and the role of syntactic reduction in Edmund Husserl’s early writings on mathematics and logic, especially on arithmetic. The notion has its origin in Hermann Hankel’s principle of permanence that Husserl set out to clarify. In Husserl’s early texts the emphasis of the reductions was meant to guarantee the consistency of the extended algorithm. Around the turn of the century Husserl uses the same idea in his conception of definiteness of what he calls “mathematical manifolds.” (...) The paper argues that the notion anticipates the notion of reduction in term rewrite theory in computer science. The role of the reduction for Husserl is, however, primarily epistemological: its purpose is to impart clarity to formal mathematics. (shrink)

In this article, we address the problem of how people understand predicative metaphors such as “The rumor flew through the office,” and argue that predicative metaphors are understood as indirect (or two-stage) categorizations. In the indirect categorization process, the verb (e.g., fly) of a predicative metaphor evokes an intermediate entity, which in turn evokes a metaphoric category of actions or states (e.g., “to spread rapidly and soon disappear”) to be attributed to the target noun (e.g., rumor), rather than directly evoking (...) a metaphoric category as argued by CitationGlucksberg's (2001) categorization theory. We test our argument using two experiments, namely, offline comprehension and online priming. The offline comprehension experiment showed that interpretation of predicative metaphors had greater overlap with words indirectly associated with the verb than those directly associated with the verb. The online priming experiment demonstrated that indirectly associated words were activated during predicative metaphor comprehension, but directly associated words were not. These results provide convergent evidence for our argument, and thus the psychological validity of two-stage categorization as a process of predicative metaphor comprehension was confirmed. (shrink)

Assessing learners’ individual differences helps identify students who need teacher support in classrooms. Previous studies have examined second language achievement based on reading anxiety because reading is an input-based activity essential for successful L2 learning. This study applied a latent rank model to identify L2 learners who are likely to be struggling or successful in classrooms according to their L2 reading anxiety symptoms. Moreover, a psychometric function was developed to determine the cutoff anxiety scores that discriminate against their substantial differences. (...) The model was applied to responses from the Foreign Language Reading Anxiety Scale provided by 335 Japanese learners of English. The results showed that the FLRAS classified students into three ranked groups with ordinal information regarding L2 reading anxiety. Rank 1 exhibited good conditions in L2 reading anxiety. Rank 2 reported high anxiety toward unfamiliar grammar during L2 reading. Rank 3 had even higher anxiety levels, especially for vocabulary and grammatical knowledge deficits and reading difficulty. The cutoff anxiety scores estimated by the model detected students who failed their L2 class with 79% accuracy. Theoretical, methodological, and pedagogical issues in language anxiety were discussed in terms of diagnosis and different approaches to teaching L2 reading. (shrink)

The ethical tension in childhood vaccination policies is often framed as one of balancing the value of choice with the duty to protect. Because infectious diseases spread from person to person, unvaccinated children are usually described as putting others around them at risk, violating a perceived right to be protected from harm. Editors of Lancet Infectious Diseases recently argued against mandatory vaccination, reminding us that the resort to mandatory vaccination as a means of achieving high vaccination rates is still very (...) much a topic of Western vaccine debates. The nation of Japan offers an interesting case study in childhood vaccination policy, as it has an entirely voluntary system that achieves high vaccination rates. In this paper, we offer an overview of Japanese childhood vaccine policy, suggest some ways to contextualize and understand how a voluntary system achieves high vaccination rates, and speculate on what the future of Japanese vaccination policymaking and government–public relations may hold.

Informed consent, decision-making styles and the role of patient-physician relationships are imperative aspects of clinical medicine worldwide. We present the case of a 74-year-old woman afflicted with advanced liver cancer whose attending physician, per request of the family, did not inform her of her true diagnosis. In our analysis, we explore the differences in informed-consent styles between patients who hold an "independent" and "interdependent" construal of the self and then highlight the possible implications maintained by this position in the context (...) of international clinical ethics. Finally, we discuss the need to reassess informed-consent styles suitable to the needs of each patient regardless of whether he or she resides in the United States or in Japan. (shrink)

AbstractThe Belmont Report continues to be held in high regard, and most bioethical analyses conducted in recent years have presumed that it affects United States federal regulations. However, the assessments of the report’s creators are sharply divided. Understanding the historic reputation of this monumental report is thus crucial. We first recount the historical context surrounding the creation of this report. Subsequently, we review the process involved in developing ethical guidelines and describe the report’s features. Additionally, we analyze the effect of (...) unfolding events on the subsequent creation of federal regulations, especially on gene therapy clinical trials. Moreover, throughout this paper we evaluate the ethical principles outlined in this report and describe how they overlap with the issue of protecting socially vulnerable groups. Based on the analysis, we conclude that the features of the Belmont Report cannot be considered as having affected the basic sections of the federal regulations for ethical reviews that were made uniform in 1981. Nevertheless, regarding the regulations on gene therapy clinical trials—which were at first expected to be applicable to research involving children—in addition to implementing policies regarding the public review of protocols that passed ethical review, this report’s principles are clearly reflected in the key notes that should have been referred to when the report was created.
