One of the central debates in the cognitive science of language has revolved around the nature of human linguistic competence. Whether syntactic competence should be characterized by abstract hierarchical structures or reduced to surface linear strings has been actively debated, but the nature of morphological competence has been insufficiently appreciated despite the parallel question in the cognitive science literature. In this paper, in order to investigate whether morphological competence should be characterized by abstract hierarchical structures, we conducted the crowdsourced acceptability (...) judgment experiment on morphologically complex words and evaluated five computational models of morphological competence against human acceptability judgments: Character Markov Models (Character), Syllable Markov Models (Syllable), Morpheme Markov Models (Morpheme), Hidden Markov Models (HMM), and Probabilistic Context-Free Grammars (PCFG). Our psycholinguistic experimentation and computational modeling demonstrated that "morphous" computational models with morpheme units outperformed "amorphous" computational models without morpheme units and, importantly, PCFG with hierarchical structures most accurately explained human acceptability judgments on several evaluation metrics, especially for morphologically complex words with nested morphological structures. Those results strongly suggest that human morphological competence should be characterized by abstract hierarchical structures internally generated by the grammar, not reduced to surface linear strings externally attested in large corpora.

This paper examines the semantics and pragmatics of the Japanese causal connective mono. We show that the meaning of mono has three components: a causal relation, an emotive attitude toward the causing proposition, and an indication that the causal relation is of high quality. Further, we show that the latter two components are not at-issue content but expressive content. A formalization is provided in terms of the analysis of mixed content in McCready (2010). Finally, the proposal is briefly compared with (...) previous, informal, accounts of the meaning of mono. (shrink)

The purpose of this paper is phe-nomenological interpretation of the various faces of divinity in the later Heidegger and elucidation of the human comportment corresponding to this divinity. In the first chapter, I will make clear the relation between ontological difference in the sense of the later Heidegger and the primordial dimension of divinity which is called the last god and the sacred. Further, the relation between such divinity and entity as a whole will be clarified. In the second chapter, (...) I will elucidate the place of the divinities in the manifestation of entity as a whole by considering the role of the godlikes in the fourfold. When the primordial alterity of the last god should be experienced in entity as whole, which leads to the notion of the godlikes, it must confront human subject in totally asymmetrical manner. Such asymmetrical communication can be structurally made explicit by taking the concept of “discourse” in Being and Time into account. Finally, I will consider the character of human comportment called preservation with focusing on its relation to the later Heidegger’s conceptions of divinity. This will shed light on how human beings could properly appreciate the experience of what is beyond our understanding and nevertheless supporting our existence.El objetivo de la ponencia es llevar a cabo una interpretación fenomenológica de las diversas facetas de la divinidad en el Hei-degger tardío y elucidar el comportamiento humano respecto de esta divinidad. En el primer capítulo, se esclarece la relación entre la diferencia ontológica en el sentido que le da el segundo Heidegger y la dimensión primordial de la divinidad, llamada el último dios y lo sagrado. A conti-nuación, se esclarecerá la relación entre la divinidad así concebida y lo ente en totalidad. En el segundo apar-tado, se elucidará el lugar de las divinidades en la manifestación de lo ente en totalidad considerando el papel de los divinos la Cuaternidad. Cuando la alteridad primordial del último dios se experimente en lo ente en totaliadd, lo cual conduce a la noción de los divinos, tiene que enfrentarse al sujeto humano de una forma totalmente asimétrica. Esta comunicación asimétrica puede explicitarse estructuralmente mediante la consideración del concepto del discurso en Ser y tiempo. Final-mente, consideraré el carácter del comportamiento humano denominado la preservación, con especial atención a su relación con la noción de lo divino en Heidegger tardío. Esto arrojará luz sobre cómo los seres humanos podrían apreciar de manera adecuada lo que está más allá de nuestra comprensión y sin embargo, sostiene nuestra existencia. (shrink)

This article considers social choice theory without the Pareto principle. We revisit the trade-off theorem developed by Campbell and Kelly (Econometrica 61:1355–1365, 1993) and generalize their result. By introducing an alternative measure of decisive structure, a dominance relation, we show that if a social welfare function dominates another social welfare function, then the number of pairs of alternatives which social ranking is independently of individual preferences under the former is not more than that under the latter. Moreover, we offer two (...) applications of our main result. (shrink)

As humans, we constantly change our movement strategies to adapt to changes in physical functions and the external environment. We have to walk very slowly in situations with a high risk of falling, such as walking on slippery ice, carrying an overflowing cup of water, or muscle weakness owing to aging or motor deficit. However, previous studies have shown that a normal gait pattern at low speeds results in reduced efficiency and stability in comparison with those at a normal speed. (...) Another possible strategy is to change the gait pattern from normal to step-to gait, in which the other foot is aligned with the first swing foot. However, the efficiency and stability of the step-to gait pattern at low speeds have not been investigated yet. Therefore, in this study, we compared the efficiency and stability of the normal and step-to gait patterns at intermediate, low, and very low speeds. Eleven healthy participants were asked to walk with a normal gait and step-to gait on a treadmill at five different speeds, ranging from very low to normal walking speed. The efficiency parameters and stability parameters were analyzed from the motion capture data and then compared for the two gait patterns. The results suggested that step-to gait had a more efficient gait pattern at very low speeds of 10–30 m/min, with a larger percent recovery, and was more stable at 10–60 m/min in comparison with a normal gait. However, the efficiency of the normal gait was better than that of the step-to gait pattern at 60 m/min. Therefore, step-to gait is effective in improving gait efficiency and stability when faced with situations that force us to walk slowly or hinder quick walking because of muscle weakness owing to aging or motor deficit along with a high risk of falling.

HIV stigma and fears surrounding the disease pose a challenge for public health interventions, particularly those that target pregnant women. In order to reduce stigma and improve the lives of vulnerable populations, researchers have recognized a need to integrate different types of support at various levels. To better inform HIV interventions, the current study draws on social-ecological and evolutionary theories of reproduction to predict stigma and fear of contracting HIV among pregnant women in South India. The aims of this study (...) were twofold: compare the social-ecological model to a modified maternal-fetal protection model and test a combined model that included strong predictors from each model. The study took place in 2008–2011 in Mysore District, Karnataka, India. Using data from a cross-sectional survey and biological indicators of health, we statistically modeled social-ecological variables representing individual, interpersonal, and community/institutional levels. Participants were 645 pregnant women. The social-ecological and combined models were the best-fitting models for HIV-related stigma, and the combined model was the best fit for HIV-related fear. Our findings suggest that combining reproductive life history factors along with individual, interpersonal, and community/institutional factors are significant indicators of HIV-related stigma and fear. Results of this study support a multifaceted approach to intervention development for HIV-related stigma and fear. The combined model in this study can be used as a predictive model for future research focused on HIV stigma and fear, with the intent that dual consideration of social-ecological and evolutionary theories will improve public health communication efforts.

Influential neoclassical economist Lionel McKenzie has made major contributions to postwar economic thought in the fields of equilibrium, trade, and capital accumulation. This selection of his papers traces the development of his thinking in these three crucial areas.McKenzie's early academic life took him to Duke, Princeton, Oxford, the University of Chicago, and the Cowles Commission. In 1957, he went to the University of Rochester to head the economics department there, and he remains at Rochester, now Wilson Professor Emeritus of Economics. (...) McKenzie's most significant research was undertaken during a period that saw the development of the major themes of neoclassical economics and the use of fundamental mathematical methods to do so. McKenzie contributed to both aspects of this research program. He helped shape the direction of the field and, at Rochester, influenced generations of future scholars. In 2002, The MIT Press published McKenzie's Classical General Equilibrium Theory, a detailed summary of the model and methodology. This book, collecting his most important papers in the form in which they were originally published, can be seen as a companion to that one. The many state-of-the-art results achieved in McKenzie's original papers present sophisticated theoretical work that will continue to be important to future developments in the discipline. (shrink)

In this paper we study a certain class of Lie algebras over commutative von Neumann algebras satisfying a certain finiteness condition. By using Boolean valued methods developed by Takeuti [8]-[11], we will establish the basic structure and representation theorems.

Just as Kaplansky [4] has introduced the notion of an AW*-module as a generalization of a complex Hilbert space, we introduce the notion of an AL*-algebra, which is a generalization of that of an L*-algebra invented by Schue [9, 10]. By using Boolean valued methods developed by Ozawa [6–8], Takeuti [11–13] and others, we establish its basic properties including a fundamental structure theorem. This paper should be regarded as a continuation or our previous paper [5], the familiarity with which is (...) presupposed. MSC: 03C90, 03E40, 17B65, 46L10. (shrink)

We used a response competition paradigm to investigate whether a distractor is effectively rejected under conditions where it is projected to a highly-loaded hemisphere. In two experiments we asked right-handed participants to identify a target among five task-relevant letters while they ignored a distractor. We manipulated both the distractor visual-field and the compatibility of the target and the distractor. In the low-loaded visual-field, we presented a distractor with one task-relevant stimulus to one visual-field and the remaining task-relevant stimuli to the (...) opposite visual-field. In the high-loaded visual-field, we presented a distractor and task-relevant stimuli in reverse. In Experiment 1 , we found a compatibility effect for the low-loaded, but not for the high-loaded visual-field. In Experiment 2, this modulation of the compatibility effect did not appear when the upper/lower visual-field was manipulated. These findings demonstrate that a distractor is successfully ignored when it is presented to a highly-loaded hemisphere. (shrink)

In conventional generalization of the main results of classical measure theory to Stone algebra valued measures, the values that measures and functions can take are Booleanized, while the classical notion of a σ-field is retained. The main purpose of this paper is to show by abundace of illustrations that if we agree to Booleanize the notion of a σ-field as well, then all the glorious legacy of classical measure theory is preserved completely.

In contemporary Japanese society, it is difficult to find a marriage partner, and therefore, “Konkatsu,” the search for a marriage partner, has become a socially accepted activity in Japan. In response to this social challenge, in addition to private companies, governments and non-profit organizations are supporting individuals in their search for a marriage partner. This paper reviews statistical information related to marriage hunting published in Japan. In addition, some of the authors’ collaborative activities and academic publications based on these activities (...) are reviewed. Subsequently, the paper discusses and highlights the importance of helping individuals have confidence in their physical attractiveness. (shrink)

In spite of the philosophical significance of higher-order modal logic, the modal logician's main concern has been with sentential logic. In this paper we do not intend to go into philosophical details, but we only remark that higher-order modal logic has a close relationship with Montague's well-known idea of “universal grammar”, which is an ambitious attempt to build a logical theory of natural languages with exact syntax and semantics, comparable with the artificial languages of mathematical logic. For this matter, the (...) reader can consult, e.g., Montague [8], [9] and Gallin [2]. (shrink)
