Ghost stochastic resonance in FitzHugh–Nagumo circuit
2014
International audience; The response of a neural circuit submitted to a bi-chromatic stimulus and corrupted by noise is investigated. In the presence of noise, when the spike firing of the circuit is analysed, a frequency not present at the circuit input appears. For a given range of noise intensities, it is shown that this ghost frequency is almost exclusively present in the interspike interval distribution. This phenomenon is for the first time shown experimentally in a FitzHugh-Nagumo circuit.
Wiener-Granger Causality in Network Physiology with Applications to Cardiovascular Control and Neuroscience
2016
Since the operative definition given by C. W. J. Granger of an idea expressed by N. Wiener, the Wiener–Granger causality (WGC) has been one of the most relevant concepts exploited by modern time series analysis. Indeed, in networks formed by multiple components, working according to the notion of segregation and interacting with each other according to the principle of integration, inferring causality has opened a window on the effective connectivity of the network and has linked experimental evidences to functions and mechanisms. This tutorial reviews predictability improvement, information-based and frequency domain methods for inferring WGC among physiological processes from multivariate…
Infant information processing and family history of specific language impairment: converging evidence for RAP deficits from two paradigms
2007
An infant's ability to process auditory signals presented in rapid succession (i.e. rapid auditory processing abilities [RAP]) has been shown to predict differences in language outcomes in toddlers and preschool children. Early deficits in RAP abilities may serve as a behavioral marker for language‐based learning disabilities. The purpose of this study is to determine if performance on infant information processing measures designed to tap RAP and global processing skills differ as a function of family history of specific language impairment (SLI) and/or the particular demand characteristics of the paradigm used. Seventeen 6‐ to 9‐month‐old infants from families with a history of specific l…
Comunicare la pandemia tra relazioni sociali, norme e vita familiare: un'analisi quali-quantitativa degli articoli Ansa durante il lockdown
2021
This paper presents the results of a double computer-assisted analysis of selected Ansa news agency texts during the domestic quarantine period (lockdown: 10 March 2020 - May 18 2020). More specifically, the research focuses on lexicon, concepts and interpretative sequences in the construction of three media metaphors: 1) “war-like and post-apocalyptic” (CBPA); 2) “segregationist and normative” (SN), 3) “reactive and participatory” (RP). Some aspects of the new social and family relations in the Covid Age thus emerge - also on the basis of the concept of ‘interactional anomie’.
The Sanremo-Effect. Exposing Rape, Normalizing Sexism.
2021
Le Festival de la chanson de Sanremo est l’un des événements médiatique plus importants d’Italie. L’édition 2020, centrée sur le thème de la violence faite aux femmes, s’est déroulée sous le feu d’une controverse qui a conduit présentateurs et spectateurs a se questionner en direct sur la « vraie » violence. Notre objectif est de comprendre ce que les normes du genre télévisuel font à la mise en discours de la violence de genre. Le résultat est paradoxal : on aboutit à normaliser le sexisme tout en dénonçant le viol. Pour mettre en perspective cet « effet-Sanremo » par rapport au débat sur la « culture du viol », on propose une cartographie des tropes qui ont structuré le discours du specta…
Body Politics and Fat Shaming
2020
Fat shaming as a concept captures all the bias ingrained in cultural values, economic orders, and hegemonic ideals that stigmatize overweight or obese bodies. From a cultural perspective, media analysis of fat shaming allows us to address the body stratification that societies have produced, that is, what now is generally known as a somatic order. The entry analyzes the cultural effects of normalization and body politics.
Explaining Causes Behind SQL Query Formulation Errors
2020
This Full Research Paper presents the most prominent query formulation errors in Structured Query Language (SQL), and maps these errors to their cognitive explanations. Understanding query formulation errors is a key to teaching SQL. more effectively. However, studies on what kind of errors novices struggle with are relatively scarce when compared to, for example, programming languages. Although committing errors is a crucial part in learning, some errors are relatively easy to fix, and their commonness is not necessarily an indication of their difficulty. Other errors, however, halt the learning process, and are never fixed by the query writer. Using a previously established error taxonomy…
Numerical Magnitude Affects Accuracy but Not Precision of Temporal Judgments
2021
A Theory of Magnitude (ATOM) suggests that space, time, and quantities are processed through a generalized magnitude system. ATOM posits that task-irrelevant magnitudes interfere with the processing of task-relevant magnitudes as all the magnitudes are processed by a common system. Many behavioral and neuroimaging studies have found support in favor of a common magnitude processing system. However, it is largely unknown whether such cross-domain monotonic mapping arises from a change in the accuracy of the magnitude judgments or results from changes in precision of the processing of magnitude. Therefore, in the present study, we examined whether large numerical magnitude affects temporal ac…
Nutrient sensing: What can we learn from different tastes about the nutrient contents in today's foods?
2019
Abstract Tastes are often described as having a nutrient-signaling function eliciting expectations about the food and its nutrient content. The objectives of this work was to investigate correlations between taste intensity and nutrient content, to evaluate the impact of competing tastes on these relationships, and to know if the content in certain nutrients could be inferred from a combination of tastes. The Food Taste Database (Martin et al., 2014) and a French Food Composition table (ANSES-Ciqual) were used to obtain a dataset combining sensory and nutritional information for 365 foods. Our results confirm the existence of several taste-nutrient relationships previously suggested by othe…
Uomini che si fanno pagare. Genere, identità e sessualità nel sex work maschile tra devianza e nuove forme di normalizzazione
2020
Tema complesso, scomodo e controverso, il fenomeno del sex work maschile si pone al crocevia della trasformazione delle maschilità e del mutamento socio-sessuale, a metà fra modelli tradizionali, configurazioni inedite e nuove forme di normalizzazione. Poco visibile ma presente negli interstizi dello spazio pubblico, il lavoro sessuale maschile riproduce le asimmetrie di genere, classe, età ed etnia che strutturano le nostre pratiche quotidiane convenzionali. Alla luce di una serie di dati etnografici raccolti dall’autore, il volume presenta per la prima volta al lettore italiano il dibattito sociologico nazionale e internazionale sui “maschi-che-vendono-sesso-ad-altri-maschi”, ricostruendo…
