This paper introduces a common-interest communication game that generates pragmatics, where meaning emerges from the use of a preexisting language under equilibrium selection driven solely by efficiency. A key feature is that the sender describes the current state to the receiver by combining preexisting statements. This approach allows us to formalize two communication frictions: (i) longer descriptions incur higher costs, and (ii) with some probability, the receiver interprets only the conventional meaning. The absence of one friction leads to some efficient (...) equilibria exhibiting pragmatics that disregards conventional meaning. However, when communication costs are sufficiently small, given the other friction, any efficient equilibrium exhibits natural pragmatics that refines conventional meaning, reflecting the context provided by the probability distribution of states. The resulting equilibrium pragmatics aligns with major linguistic theories, including Grice’s cooperative principle (1975) and Sperber and Wilson’s relevance theory (1986). (shrink)

This paper examines the challenge of mediating theory and practice in pedagogy, specifically focusing on the critical importance of educational tact as a mediator between the two. It first defines the role of pedagogical tact, underlining its significance as a vital skill for professionals. It also explores the qualities of teachers who embrace diversity and foster intercultural understanding, which is essential and crucial in our increasingly globalized world. Moreover, it underscores the unique role of pedagogical tact in haptic research, a (...) field of growing significance in the digital age. Haptic research involving the sense of touch is pivotal in advancing digital technologies such as artificial intelligence. The paper concludes that modernizing pedagogical tact can forge a comprehensive learning environment that addresses the needs of the times. (shrink)

Para Hume, filosofar é uma atividade semelhante às demais ocupações humanas. A decisão que leva à atividade filosófica é menos resultado de uma argumentação teórica do que fruto de um cálculo prático, que é entendido como uma caça ou um jogo. O objetivo deste trabalho será o de mostrar que no jogo filosófico perde quem joga sério demais. A aposta na filosofia tem que passar pelo bom humor e pela diversão: uma resposta a Pascal? For Hume, philosophy is in itself (...) neither more nor less important than other human activities. On the contrary, it can be explained from its resemblance with game and hunting. If one chooses to dedicate himself to philosophy, his decision is not the consequence of logical reasoning, but depends on practical evaluation, which has something to do with gambling. The following text tries to show that in philosophy, like in other games, the loser will be the one who plays too earnestly. The philosophical game requires good humour and some relaxation: Is this a good answer to Pascal's pari? (shrink)

われわれは「生命」をどのように捉えてきたか。古今東西の哲学・宗教から最先端の分子生物学に至る人類の精神的営為を渉猟しつつ、多様な危機に混迷する現代に新たな生命原理主義を樹立する画期的労作。.

A formal and functional study of the three meters of Old Norse eddic poetry, fornyroislag, malahattr, and ljooahattr, this book provides their systematic account (synchronic, diachronic, and from a comparative Germanic perspective). With thorough data presentation, detailed philological analysis, and sophisticated linguistic explanation, it will be of interest to Germanic philologists/linguists, medievalists, and metrists of all persuasions.".

The physical appearance of a robot can significantly affect interactions between humans and robots. Consequently, it is imperative to elucidate the visual factors that affect these interactions. This study aimed to ascertain the influence of a robot’s physical attractiveness by investigating whether an attractive robot is preferred and whether it creates a positive impression in a communication context. Two groups of stimuli were used in the experiment: one consisted of attractive and non-attractive robots. In Study 1, 567 adult men and (...) women participated in an online survey. The results revealed a significant preference for the attractive robot group in the communication situations. In Study 2, 931 adult men and women participated in an online survey, and the findings indicated that attractive robots received more favorable ratings in terms of human- and communication-related attributes. This study substantiates the significance of physical attractiveness in the context of human–robot interactions. This underscores the need to deliberate upon and study the phenomenon of beauty bias within the field of human–robot interaction. (shrink)

This paper considers the boundary that separates marketable from non-marketable items. First, it examines the issue of blocked exchanges, that is, exchanges that cannot and/or should not take place. Second, it proposes to synthesise the seemingly separate issues of blocked exchanges from a single perspective based on critical realist ontology. Finally, it tackles some scepticism and criticism that has been levelled against the idea that ontology can be useful in determining a market boundary.

Extending techniques of Dowd and those of Poizat, we study computational complexity of in the case when is a generic oracle, where is a positive integer, and denotes the collection of all -query tautologies with respect to an oracle . We introduce the notion of ceiling-generic oracles, as a generalization of Dowd's notion of -generic oracles to arbitrary finitely testable arithmetical predicates. We study how existence of ceiling-generic oracles affects behavior of a generic oracle, by which we show that is (...) not a subset of is comeager in the Cantor space. Moreover, using ceiling-generic oracles, we present an alternative proof of the fact (Dowd) that the class of all -generic oracles has Lebesgue measure zero. (shrink)

This note is a continuation of our former paper ''Complexity of the r-query tautologies in the presence of a generic oracle.'' We give a very short direct proof of the nonexistence of t-generic oracles, a result obtained first by Dowd. We also reconstitute a proof of Dowd's result that the class of all r-generic oracles in his sense has Lebesgue measure one.

The relativized propositional calculus is a system of Boolean formulas with query symbols. A formula in this system is called a one-query formula if the number of occurrences of query symbols is just one. If a one-query formula is a tautology with respect to a given oracle A then it is called a one-query tautology with respect to A. By extending works of Ambos-Spies (1986) and us (2002), we investigate the measure of the class of all oracles A such that (...) the set of all one-query tautologies with respect to A does not p-btt-reduce to A, where p-btt denotes polynomial-time bounded-truth-table. We show that certain Dowd-type generic oracles all belong to the class, and hence measure of the class is one. (shrink)
