Orígenes de las movilizaciones #primaveravalenciana. Un análisis de los actores sociales más influyentes en Twitter
2018
Twitter publics have become consolidated research objects. The main aim of this article is to make a contribution to this research current by analysing the social conditions that gave shape to the hashtag #primaveravalenciana. In order to do this, this study shall follow an analysis of the early tweets giving shape to this phenomenon. This approach shall stablish a participant's typology, identifying the most influent actors and pursuying a content analysis of relevant micro-messages which pushed forward the hashtag's viral expansion in the next few days. Against theories which tend to minimise the social distinction of digital actors, data analysis shows that the hashtag's origins were in …
PRATIQUES INFO-COMMUNICATIONNELLES ET MOBILISATION SOCIALE À L'ÈRE D'INTERNET : LE CAS DE L'ITALIE
2013
Ce travail de recherche porte sur le rôle des pratiques info-communicationnelles de l'Internet dans la constitution, le développement et la mobilisation des nouveaux groupes contestataires en Italie. Avec cette approche, nous souhaitons porter notre attention sur les pratiques humaines et non pas sur les réseaux informationnels, considérés trop souvent comme le moteur déterminant du changement social. Ainsi, bien que l'essor d'Internet n'ait pas impliqué le passage à une forme de société plus émancipée, la création d'espaces informationnels indépendants représente néanmoins un enjeu politique important. L'enquête de terrain est structurée en deux volets, l'un portant sur l'analyse de la mob…
The New Moral Power of Minorities
2018
The model of three interrelated social entities proposed by Gabriel Mugny to account for the role of active minorities in social innovation and change retains all its relevance and heuristic value (cf. Mugny, 1982). However, the fight of the civil rights movements of the ’60s transformed the moral perspective from which the majority regards their own behaviors towards social minorities. This resulted in an immorality judgment of discriminatory attitudes and behaviors that had long been regarded as natural. Thus a change has been effected on the relationships between majority and minority groups, providing minorities with a new moral power. As a result of such a new moral representation of p…
''Forward to the past''
2012
Carlini, Alessandro | Actis-Grosso, Rossana | Stucchi, Natale | Pozzo, Thierry; International audience; ''Our daily experience shows that the CNS is a highly efficient machine to predict the effect of actions into the future; are we so efficient also in reconstructing the past of an action? Previous studies demonstrated we are more effective in extrapolating the final position of a stimulus moving according to biological kinematic laws. Here we address the complementary question: are we more effective in extrapolating the starting position (SP) of a motion following a biological velocity profile? We presented a dot moving upward and corresponding to vertical arm movements that were masked i…
Does the brain know who is at the origin of what in an imitative interaction?
2012
International audience; Brain correlates of the sense of agency have recently received increased attention. However, the explorations remain largely restricted to the study of brains in isolation. The prototypical paradigm used so far consists of manipulating visual perception of own action while asking the subject to draw a distinction between self- versus externally caused action. However, the recent definition of agency as a multifactorial phenomenon combining bottom-up and top-down processes suggests the exploration of more complex situations. Notably there is a need of accounting for the dynamics of agency in a two-body context where we often experience the double faceted question of w…
Image Content Enhancement Through Salient Regions Segmentation for People With Color Vision Deficiencies
2019
Color vision deficiencies affect visual perception of colors and, more generally, color images. Several sciences such as genetics, biology, medicine, and computer vision are involved in studying and analyzing vision deficiencies. As we know from visual saliency findings, human visual system tends to fix some specific points and regions of the image in the first seconds of observation summing up the most important and meaningful parts of the scene. In this article, we provide some studies about human visual system behavior differences between normal and color vision-deficient visual systems. We eye-tracked the human fixations in first 3 seconds of observation of color images to build real f…
Orígenes de las movilizaciones #primaveravalenciana : un análisis de los actores sociales más influyentes en Twitter
2018
Los públicos de Twitter se han convertido en un objeto de investigación social claramente consolidado. El objetivo del trabajo es contribuir a esta corriente de investigación con el análisis de las condiciones sociales que favorecieron la expansión de la etiqueta #primaveravalenciana. Para ello, nos centraremos en la etapa inicial de la etiqueta, estableciendo una tipología de participantes, identificando a los actores más influyentes y realizando un análisis de contenido de los micro-mensajes que fomentaron la expansión viral de la etiqueta en los días posteriores. Frente a las teorías que tienden a minimizar las distinciones sociales en las interacciones de las redes sociales, el análisis…
Alachlor and Bentazone Losses from Subsurface Drainage of Two Soils
2004
International audience; Atrazine (6-chloro-N2-ethyl-N4-isopropyl-1,3,5-triazine-2,4-diamine) is frequently detected at high concentrations in ground water. Bentazone [3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide] plus alachlor (2-chloro-2',6'-diethyl-N-methoxymethylacetanilide) is a potential herbicide combination used as a substitute for atrazine. Thus, the objective of this study was to assess the environmental risk of this blend. Drainage water contamination by bentazone and alachlor was assessed in silty clay (Vertic Eutrochrept) and silt loam (Aquic Hapludalf) soils under the same management and climatic conditions. Drainage volumes and concentrations of alachlor and bent…
Leaching of glyphosate and AMPA under two soil management practices in Burgundy vineyards (Vosne-Romanée, 21-France)
2005
Some drinking water reservoirs under the vineyards of Burgundy are contaminated with herbicides. Thus the effectiveness of alternative soil management practices, such as grass cover, for reducing the leaching of glyphosate and its metabolite, AMPA, through soils was studied. The leaching of both molecules was studied in structured soil columns under outdoor conditions for 1 year. The soil was managed under two vineyard soil practices: a chemically treated bare calcosol, and a vegetated calcosol. After 680 mm of rainfall, the vegetated calcosol leachates contained lower amounts of glyphosate and AMPA (0.02% and 0.03%, respectively) than the bare calcosol leachates (0.06% and 0.15%, respectiv…
Visual exploration of face and facial expression in infancy: A qualitative approach of cognitive and social development
2016
International audience; This article proposes a methodological consideration for the use of "head free" eye-tracking systems, which allowed to extend this technique to the study of infant skills. It explores how the technological developments enable a more qualitative approach, which offers the possibility of considering "how" in addition to "how long" the infant looks at a visual scene, especially the scene of the face.
