Host chemical footprints induce host sex discrimination ability in egg parasitoids
2013
Trissolcus egg parasitoids, when perceiving the chemical footprints left on a substrate by pentatomid host bugs, adopt a motivated searching behaviour characterized by longer searching time on patches were signals are present. Once in contact with host chemical footprints, Trissolcus wasps search longer on traces left by associated hosts rather than non-associated species, and, in the former case, they search longer on traces left by females than males. Based on these evidences, we hypothesized that only associated hosts induce the ability to discriminate host sex in wasps. To test this hypothesis we investigated the ability of Trissolcus basalis, T. brochymenae, and Trissolcus sp. to disti…

Adaptación de tres variables contextuales en estudiantes universitarios argentinos
2017
Una de las dificultades que han presentado los estudios destinados a identificar las causas de deserción universitaria es la falta de consideración de variables sociales/contextuales que, según se ha demostrado en la literatura, se relacionan con el proceso de progresión de la carrera. Para la evaluación de dichas variables, el primer paso consiste en la adaptación de pruebas que permitan su medición. Por lo cual, el objetivo del presente trabajo consistió en la adaptación de las escalas de Apertura a la Diversidad, Percepción de Prejuicios y Discriminación y Experiencias Académicas. En este estudio participaron 1295 estudiantes que se encontraban cursando diferentes carreras en la Universi…
Infants and Children Making Sense of Scents
2017
This chapter summarizes research on the development of human olfactory skills to rely on different cues conveyed by odorants, such as odor quality, intensity, position in space, novelty/familiarity, and hedonic value. The sensory, neural, and psychological dimensions at the root of these early aptitudes remain poorly explored in humans, but one can safely affirm that any weak odor to which the infant has previously been nonadversely exposed will have a higher reinforcing value than any novel odor. Developmental differences in odor discrimination and appreciation are certainly causally multiple and may depend on general or olfaction-specific cognitive factors which can be traced back to pren…
Discovering the Discriminating Power in Patient Test Features Using Visual Analytics: A Case Study in Parkinson’s Disease
2016
Part 11: New Methods and Tools for Big Data Wokshop (MT4BD); International audience; This paper presents a novel methodology for selecting the most representative features for identifying the presence of the Parkinson’s Disease (PD). The proposed methodology is based on interactive visual analytic based on multi-objective optimisation. The implemented tool processes and visualises the information extracted via performing a typical line-tracking test using a tablet device. Such output information includes several modalities, such as position, velocity, dynamics, etc. Preliminary results depict that the implemented visual analytics technique has a very high potential in discriminating the PD …
Are transposition effects specific to letters?
2010
Recent research has consistently shown that pseudowords created by transposing two letters are perceptually similar to their corresponding base words (e.g., jugde–judge). In the framework of the overlap model (Gomez, Ratcliff, & Perea, 2008), this effect is due to a noisy process in the localization of the “objects” (e.g., letters, kana syllables). In the present study, we examine whether this effect is specific to letter strings or whether it also occurs with other “objects” (namely, digits, symbols, and pseudoletters). To that end, we conducted a series of five masked priming experiments using the same–different task. Results showed robust effects of transposition for all objects, ex…
A wavelet Methodology for EEG Time-frequency Analysis in a Time Discrimination Task
2009
EEG signals recorded by surface electrodes placed on the scalp can be thought as non- stationary stochastic processes in both time and space, especially in response to external stimuli. Cognitive tasks, in particular, are reflected by changes in EEG dynamics concerning both rhythms energy and connectivity across different brain regions. In the frequency-domain, EEG analysis is complicated and time-frequency methodologies are needed. The Wavelet Transform, in particular, represents a powerful tool for analysing, within a time-frequency embedding, the EEG. In this study we applied a wavelet-based methodology to extract quantitative time-frequency parameters from EEG signals recorded during a …
Effets du lieu de résidence en ZUS sur les parcours et le sentiment de discrimination des jeunes issus de l'immigration
2015
Les trajectoires professionnelles des jeunes sont influencées par de multiples contraintes qui tiennent à leurs caractéristiques, à leur cursus scolaire antérieur et aussi à l’espace social et économique dans lequel ils évoluent. Les jeunes issus de l’immigration sont davantage pénalisés pour trouver un emploi, de manière accentuée s’ils sont originaires du Maghreb et d’Afrique subsaharienne et résident dans des quartiers défavorisés. Un chômage persistant et des orientations contraintes au cours de leur formation initiale induisent un sentiment de discrimination à l’embauche éprouvé par ces jeunes.
Parcours d'insertion et sentiment de discrimination des secondes générations en Zus
2011
National audience; Dans cet article, il s'agit d'appréhender l'effet de l'organisation de l'espace sur les opportunités des secondes générations et sur leur sentiment de discrimination, en mobilisant l'enquête Génération 2004 du Céreq, base de données privilégiée pour l'analyse de l'entrée des jeunes dans la vie active. Le contexte joue-t-il de la même façon pour les jeunes nés en France de parents immigrés et les Français d'origine ? Le sentiment de discrimination perçu par les jeunes femmes et les jeunes hommes évolue-t-il en fonction de la résidence en zone urbaine sensible ?
