Moors and Christians in the Sicilian figurative and performance tradition

2021

Among the different forms of the East/West dichotomy, one is recursive in the Sicilian figurative and performative tradition: the opposition between Moors and Christians. From ex-voto paintings to some traditional festivals and, above all, puppet theatre, this dichotomy grounds a cosmology, a reference system to convey an order to the world. This essay presents some examples.

Defining and Operationalizing Appropriation for Science Learning

2014

The overarching goal of this paper is to contribute to our understanding of the interplay between students’ disciplinary engagement and their identity construction. The term appropriation, borrowed from scholars in linguistics and education, was chosen to capture this broader sense of productive learning that sits at the nexus of disciplinary engagement and identity. Appropriation implies productive learning including deep conceptual understanding, but it also involves a reflexive process of populating scientific discourse with personal intentions, purposes and tastes that allow a student to embody scientific discourse and concepts in a way that is authentic and personal. The core aim of th…

Behavioral and hippocampal evoked responses in an auditory oddball situation when an unconditioned stimulus is paired with deviant tones in the cat: …

1995

Event-related potentials (ERP) in the areas CA1, CA3 and dentate fascia (Df) of the hippocampal formation were recorded during an oddball situation in the cat. A rewarding electrical stimulation of the lateral hypothalamus (US) was paired with deviant tones (2500 Hz) that occurred randomly in a series of the standard tones (2000 Hz) given to the left ear. In addition to developing orienting head movements to the side of the deviant tones, an increase in the amplitude of parallel hippocampal ERPs was observed. Both the behavioral and neural responses appeared not until a 50 ms latency range. Furthermore, time-amplitude characteristics of the ERPs corresponded to time-acceleration characteris…

The frontal agranular cortex and the organization of purposeful movements

1985

A critical review of the traditional concepts of cortical association and motor areas is followed by a description of the functional organization and intrinsic and extrinsic cortical connectivity of the arcuate premotor area (APA). It is concluded that the frontal cortical organization of externally triggered purposeful movements is made possible by the associative character of Brodmann's area 6 and by its peculiar pattern of intra-areal connectivity.

Entre politique et disciplinaire : les études médiévales en Europe et en Amérique latine. Perspective

2010

L'exercice d'auto-réflexion disciplinaire qui est l'objet de ce volume se place dans la suite d'une série de bilans qui, dans les années 1980 et surtout à partir des années 1990, ponctuent périodiquement les études sur le Moyen Âge . En tenant compte de ce socle considérable, ce recueil se présente sous la forme de bilans par discipline - histoire, histoire de l'art, archéologie, littérature - et par pays - Argentine, Brésil, Chili, Espagne, Portugal, France, centrés, sans exclusive, sur les trois dernières décennies. Il juxtapose ainsi une série de cas particuliers dont la portée réside aussi dans les leçons qu'on peut en tirer à un niveau plus élevé de généralisation. Au delà de tout l'in…

Soldier formation regulated by a primer pheromone from the soldier frontal gland in a higher termite, Nasutitermes lujae

1984

In the nasute higher termite Nasutitermes lujae , the differentiation of new soldiers is suppressed or delayed by the soldiers themselves. Experimental data strongly suggest that this inhibitory effect results from the action of a primer pheromone secreted by the frontal gland of soldiers. The pheromone must be contacted directly. Thus, the frontal gland of termite soldiers assumes a new role in addition to alarm and defense, although this extension cannot be generalized to all termite species. The soldier inhibitory pheromone is evidently only one of multiple factors contributing soldier regulation in termite societies.

The perception of infant emotions is an integral part of sensitive caregiving within the mother-child relationship, a maternal ability which develops in mothers during their own attachment history. In this study we address the association between maternal attachment representation and brain activity underlying the perception of infant emotions. Event related potentials (ERPs) of 32 primiparous mothers were assessed during a three stimulus oddball task presenting negative, positive and neutral emotion expressions of infants as target, deviant or standard stimuli. Attachment representation was assessed with the Adult Attachment Interview during pregnancy. Securely attached mothers recognized …

Biodiversidad en el Siglo XXI: más allá del conteo de especies

2018

In modern ecology, the traditional diversity indexes (usually of richness, abundance, and species evenness) have been highly revealing and useful for monitoring community and ecosystem processes. However, around two decades ago, a pioneering research team noticed that these indexes did not completely resolve their open questions. Thus, they suggested changing the way biodiversity was measured. At its base, this new methodology considers the distance between species (in phylogenetic or functional terms) before subsequently applying the appropriate biodiversity indexes. Including phylogenetic and functional elements in the evaluation of diversity allows us to approach the concept of biodivers…

The Relationship Between Polygenic Risk Scores and Cognition in Schizophrenia

2020

Abstract Background Cognitive impairment is a clinically important feature of schizophrenia. Polygenic risk score (PRS) methods have demonstrated genetic overlap between schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), educational attainment (EA), and IQ, but very few studies have examined associations between these PRS and cognitive phenotypes within schizophrenia cases. Methods We combined genetic and cognitive data in 3034 schizophrenia cases from 11 samples using the general intelligence factor g as the primary measure of cognition. We used linear regression to examine the association between cognition and PRS for EA, IQ, schizophrenia, BD, and MDD. The results wer…
