A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co‐vary with other non‐verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behaviors. We used a computer‐generated animated pedagogical agent to control both verbal and non‐verbal behavior. Children viewed lessons on mathematical equivalence in which an (...) avatar either gestured or did not gesture, while eye gaze, head position, and lip movements remained identical across gesture conditions. Children who observed the gesturing avatar learned more, and they solved problems more quickly. Moreover, those children who learned were more likely to transfer and generalize their knowledge. These findings provide converging evidence that gesture facilitates math learning, and they reveal the potential for using technology to study non‐verbal behavior in controlled experiments. (shrink)

From Gnỗthi seautόn (‘Know Thyself’) to cognitive theories of the self there has been a long time, but the paradigm has almost remained the same. This article proposes a reconsideration of their rediscovery filtered through Jean Rhys’ post-colonial sensitivity. Between the ‘core self’ and its iridescent, exotic edges, broadly speaking, the thoroughly analyzed facets of cultural identity interpose.

An Internet-based competitive marketing game, FIFA 20, served to investigate the effectiveness of two opposite strategies in soccer-player auctions under semi-naturalistic conditions. Granting the validity of both causal principles, the anchoring principle giving an advantage to starting with a high price (Ritov, 1996) and the traffic principle underlying the starting-low advantage (Ku, Galinsky, & Murnighan, 2006), we nevertheless expected starting low strategies to produce higher end-prices under FIFA 20 conditions. Two experiments, each using multiple copies of two players from the (...) lowest price segment (Kramaric, Pizzi) and from an elevated price segment (Laporte, Martial), corroborated these expectations. A starting-low advantage was evident in two utility aspects, enhanced average (profit) and reduced variance (uncertainty aversion) of end prices obtained for player copies offered at lower starting prices. However, when the causal impact of the manipulated starting value was overshadowed by extraneous media influences, these findings were reduced or disappeared but never reversed. (shrink)

In the conventional approach to quantum mechanics, indeterminism is an axiom and nonlocality is a theorem. We consider inverting the logical order, making nonlocality an axiom and indeterminism a theorem. Nonlocal “superquantum” correlations, preserving relativistic causality, can violate the CHSH inequality more strongly than any quantum correlations.

The paper proposes a flexible way to build concepts within fuzzy logic and set theory. The framework is general enough to capture some important particular cases, with their own independent interpretations, like “antitone” or “isotone” concepts constructed from fuzzy binary relations, but also to allow the two universes to be equipped each with its own truth structure. Perhaps the most important feature of our approach is that we do not commit ourselves to any kind of logical connector, covering thus the (...) case of a possibly non-commutative conjunction too.

La communication se rapporte à la richesse des interprétations temporelles par l’intermédiaire de Vintila Horia, l’une des personnalités du XX‐e siècle, qui l’applique à l’histoire du monde par ses personnages, leurs époques et les conceptions de vie correspondantes, phénomène exprimé à l’aide de l’art littéraire d’une complexité particulière, invitant à la méditation et aux réactions nécessaires. Le but de sa création est d’éclaircir la personnalité humaine dans sa variété expressive, modulée par le contexte philosophique dans lequel chacun réagit conformément à (...) sa raison et aux procès à caractère social, politique et culturel caractéristiques à la société décrite.

Severian of Gabala’s homilies and Pseudo-Theodoret’s Quaestiones et responsiones ad Orthodoxos exhibit some notable parallels. Such links show that a marginal current of the Antiochene school was still thriving by the end of the 5th century, i.e. the most probable date of QRO.

The earliest instance of φωτιστήριον « baptistery » in Antioch appears in the year 517, in a Syriac gloss to one of Severus’s homilies, perhaps in connectionwith his pastoral policies. Even if φωτιστήριον was formed according to same pattern as βαπτιστήριον, both nouns seem independent. John Chrysostom and an Antiochian Pseudo-Chrysostom do not mention at all the baptistery, but only the font (κολυμβήϑρα). The evidence indicates that during the 5th century φωτιστήριον was almost exclusively used in Constantinople and might have (...) been created there. Some texts indicate that the word might have been the preferred name for the baptistery of a « cathedral » church, at least in Constantinople. (shrink)

According to Cornelis Datema, the still mysterious Leontius of Con-stantinople preached sometime around 557, whereas Michel Asmus places him between the end of the 4th century and the mid-5th century. This paper contends that the memory of a deceased bishop that closes the homily Nat. refers to Theodore I, patriarch of Constantinople, who died on 28 December 687. The article also shows that Leontius cannot possibly have lived earlier than the mid-6th century.

We prove an institutional version of A. Robinson ’s Consistency Theorem. This result is then appliedto the institution of many-sorted first-order predicate logic and to two of its variations, infinitary and partial, obtaining very general syntactic criteria sufficient for a signature square in order to satisfy the Robinson consistency and Craig interpolation properties.
