Virtudes escolares percibidas por estudiantes y docentes ecuatorianos: diferencias según sexo, establecimiento y roles
2020
El objetivo del estudio es evaluar la virtuosidad percibida en organizaciones escolares y las diferencias por tipo de centro educativo (fiscal, municipal); sexo (mujer, hombre) y rol (estudiantes, docentes). Se trató de un estudio instrumental basado en el análisis de la estructura factorial y la fiabilidad de un cuestionario para evaluar virtudes percibidas en escuelas (VPOE); y, de un estudio descriptivo transversal que analizó diferencias por sexo, rol y tipo de organizaciones escolares con relación a las virtudes percibidas. Se trabajó con una muestra de 550 estudiantes (49.28 % mujeres) y 105 docentes (47.62% mujeres). El análisis factorial determinó un modelo de cuatro factores que pe…

Sensory systems sequentially extract increasingly complex features. ON and OFF pathways, for example, encode increases or decreases of a stimulus from a common input. This ON/OFF pathway split is thought to occur at individual synaptic connections through a sign-inverting synapse in one of the pathways. Here, we show that ON selectivity is a multisynaptic process in the Drosophila visual system. A pharmacogenetics approach demonstrates that both glutamatergic inhibition through GluClα and GABAergic inhibition through Rdl mediate ON responses. Although neurons postsynaptic to the glutamatergic ON pathway input L1 lose all responses in GluClα mutants, they are resistant to a cell-type-specifi…
Extraction d'un graphe de navigabilité à partir d'un nuage de points 3D enrichis
2017
International audience; Ce travail se place dans le cadre général du projet ANR pLaTINUM lié à la navigation autonome et plus parti-culièrement à la génération de cartes pour la navigation basée perception. Il consiste à développer une nouvelle méthode pour résumer une carte 3D (un nuage dense de points 3D) et extraire un graphe de navigabilité facilitant l'utilisation de cette carte par des systèmes de navigation à ressources matérielles limitées (smart-phones, voitures, robots.. .). Cette méthode vise à ex-traire les régions les plus saillantes de l'environnement étudié afin de construire une carte récapitulative. Ce processus de résumé de carte basé sur la vision est appliqué d'une façon…
Fenomenologia e Cognitive Vision
2012
Vernon (2006) suggerisce di individuare un consenso in Cognitive Vision nella ricerca di capacità e attributi non-funzionali per un sistema robusto e adattivo. Questo contributo presenta una teoria informale di capacità percettive e motorie corrispondenti alle proprietà spaziali fenomeniche degli oggetti, vale a dire ai percetti la cui struttura è studiata in fenomenologia della percezione. Infine, se ne illustrano alcune implicazioni rispetto alle teorie cognitiviste e sensomotorie.

Publisko personu komercdarbība valsts atbalsta kontekstā
2015
Publiskas personas bieži izvēlas rīkoties privāto tiesību jomā, īpaši komercdarbībā. Vienlaikus jāņem vērā, ka šāda rīcība var radīt draudus konkurencei, tāpēc svarīgi analizēt, kādos gadījumos un ar kādiem nosacījumiem publiska persona drīkst iesaistīties tirgū, pati nodarbojoties ar komercdarbību. Darbā pētīta publiskās personas komercdarbība valsts atbalsta kontekstā, analizējot, kādos gadījumos tā atļauta un kādi ir tās ierobežojumi.
Motion perception in early glaucoma
2013
Purpose: The aim of our study was to underline the changes in the movement perception for early glaucoma. Our working hypothesis consisted in inquiring if the impairment of the magnocellular pathway may modify the movement perception capabilities in the visual field, more particularly in its peripheral area.Methods: We included 14 healthy subjects and 14 patients with early primary open angle glaucoma. A moving target was presented on a semicircular screen (1.8 m diameter); participants were asked to localize the Ending Point (EP) of each movement. Each stimulus consisted in a white dot (0,72° of diameter) moving horizontally with the imposed velocity profile. Two different laws of motion w…
Long-term physical activity modifies automatic visual processing
2019
Electrophysiologically registered visual mismatch negativity (vMMN) is known to represent automatic visual processing in human visual cortex. Since physical activity (PA) is generally beneficial to cerebrovascular function, we wanted to find out if automatic visual processing is affected by PA. We investigated the connection between long-term leisure-time PA and precognitive visual processing in 32 healthy young males. Participants were divided into active (n = 16) and inactive (n = 16) group according to their leisure-time PA records from the past three years. vMMN was recorded with electroencephalogram using passive oddball paradigm with visual bars. Standard (90%) and deviant (10%) stimu…
“Voz del alumnado”: hacer de los estudiantes participantes activos y responsables en los procesos formativos activados en la escuela y en la universi…
2017
"Voce degli studenti" è un movimento pedagogico nato negli anni novanta in alcuni paesi di lingua inglese (Stati Uniti, Canada, Inghilterra e Australia). Supporta la partecipazione attiva e responsabile degli studenti ai processi di formazione attivati nella scuola e nell'università. Per includere le voci degli studenti in questi processi, gli adulti (insegnanti e amministratori) devono riconoscere i loro diritti di essere ascoltati e rispettati come persone con interessi, bisogni di apprendimento e idee che possono risolvere i problemi della didattica scolastica/universitaria, della ricerca educativa e delle politiche culturali in cui si devono prendere decisioni che li riguardano. In ques…
Active volcanoes as emission point sources of atmospheric mercury
2008
ercury emissions from active volcanoes are of interest for estimating the volcanogenic contribution of Hg to the atmosphere and for monitoring volcanic activity. The global Hg flux from natural sources is poorly known and considerable uncertainty still exists with respect to the complex physical and chemical reactions taking place in the atmosphere among the various Hg forms. The environmental hazard of Hg have been widely demonstrated for its high toxicity. Previous estimates from volcanic plumes are based on limited measurements and poorly determined speciation of Hg in volcanic emissions which is crucial for making reliable estimates of volcanic Hg source strengths and for predicting atm…
