Exploration trans-échelles d'une ville nouvelle à l'aide de l'analyse multiradiale
2017
National audience; L’analyse spatiale du bâti repose généralement sur des indicateurs de caractéristiques morphologiques absolues des bâtiments (taille, élongation, compacité, orientation) ou relatives (espacements, positions par rapport au voisinage, position par rapport au réseau), dont on calcule ensuite la distribution statistique, ou quelques résumés de cette distribution, comme la moyenne et l’écart-type. Ces mesures sont efficaces pour décrire l’aspect du tissu bâti (Regnault 2002, Sabo et al. 2005), mais souffrent d’une limitation importante : elles sont purement locales, et ne disent rien, ou presque, de l’organisation spatiale du bâti à d’autres échelles qui sont celles des quarti…
L’aire urbaine de Valencia dans le système global des villes : Les effets de la crise économique sur le réseau des liens financiers des entreprises m…
2021
El artículo analiza el impacto que la crisis económica ha tenido sobre las redes de relaciones de propiedad-filiación de las empresas multinacionales, consideradas en la literatura científica como uno de los factores más importantes en la integración de las ciudades en la globalización. El caso de estudio es el área metropolitana de Valencia, un centro de segundo nivel en las redes económicas mundiales que ha sido duramente golpeado por los efectos de la crisis desde 2008. A partir del análisis de bases de datos de empresas multinacionales en dos fechas de referencia, 2010 y 2013, se constata que la crisis económica ha provocado un retroceso en la inserción del área metropolitana en dichas …
Vins d’appellations et gastronomie régionale. La genèse bourguignonne d’un modèle novateur (années 1920-1930)
2016
Boire du vin au restaurant, le choisir ou le faire choisir en fonction du plat sélectionné, étudier la carte des boissons tout comme le menu, ou encore commenter les domaines et les millésimes, sont des actes totalement intégrés par les amateurs de gastronomie du XXIe siècle. Et même si les associations mets vins tendent à s’internationaliser, déguster un produit local avec un vin du cru reste un moment important pour nombre de personnes souhaitant visiter une région. Cette démarche, si commune aujourd’hui, résulte pourtant d’un processus historique finalement assez récent et dont l’évidence contemporaine n’a rien de manifeste historiquement. En France au début du XXe siècle seulement, et d…
Geografie marginali: la mappa e il tempo del piccolo globo virale (Dialogo tra AB e GdS)
2022
A partire dal Meridiano di Paul Celan, tra geografia e retorica, si stabilisce un rapporto tra la fase virale del capitalismo e la virale pandemia. Sul versante della retorica, il meridiano si connette al linguaggio dei media e delle comunicazioni ufficiali che utilizza il termine mappa per mettere in immagine la diffusione del Covid-19. Termine che per i geografi significa tecnicamente panno del mondo, ossia qualcosa che avvolge e circonda il mondo con pieghe e intensit�� in un registro temporale di crisi irriducibile alla ragione reticolare e allo spazio sincronico contemporaneo (Olsson, 2007). �� la proiezione di una simile ���mappamundi virale��� a ridisegnare il contenuto del globo att…
Why viruses sometimes disperse in groups?
2019
AbstractMany organisms disperse in groups, yet this process is understudied in viruses. Recent work, however, has uncovered different types of collective infectious units, all of which lead to the joint delivery of multiple viral genome copies to target cells, favoring co-infections. Collective spread of viruses can occur through widely different mechanisms, including virion aggregation driven by specific extracellular components, cloaking inside lipid vesicles, encasement in protein matrices, or binding to cell surfaces. Cell-to-cell viral spread, which allows the transmission of individual virions in a confined environment, is yet another mode of clustered virus dissemination. Nevertheles…
Shooting borders. Per una geogafia visuale delle migrazioni
2017
Our perceptions of events in the Mediterranean are strongly influenced by a range of visual practices that impact on both the emotional and the political. In this paper, I set out to critically explore the visual geographies underlying photographic images of contemporary migration flows across the Mediterranean Sea. I argue the need for a methodological shift from a content analysis approach to a critical investigation of the spatial interweaving of images, gazes and aesthetic regimes that governs both the production and reception of such photographs. Given these theoretical premises, I focus on three images of migrants being rescued in the Mediterranean to illustrate how photography can ac…
Visual Methodologies and Geography's education in the pandemic time: notes on geopolitics of migration in the "Mediterranean Complex"
2022
<abstract> <p>The relationship between Geography and the Visual has always been strong intertwined. As it is true that Geography has always operates through images (in the form of pictures, creative representations and above all cartographies), in the last two years, with the distance learning due to the spread of the Covid-19 pandemic, this phenomenon has not only increased, but it also became necessary. "The classroom as the most radical space", in the words of bell hooks, had to turn into a virtual space, where images have a fundamental role in the teaching/learning process. This paper wants to analyse the relationship between Geography and the Visual by analysing three image…
Proposition méthodologique pour la visualisation et l'exploration des mobilités géographiques
2016
Daily mobility data are multidimensional and desaggregated, what make them hard to manipulate and to analyze. Although methods of representation and analyze have been proposed, none of them seem to be able to efficiently bring out knowledge from data. We propose to combinate this solutions and a methodology of innovative reaggregation to visualize and explore mobility data.
Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates
2021
We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops. A survey of the perception of the farmers, and an assessment of the biophysical impact of catch crops (CC) and tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (single ring infiltrometer), and runoff generation and soil erosion (rainfall simulation experiments) was carried out. Two representative fields as study sites were selected in Les Alcusses valley, within Els Alforins…
El alojamiento colaborativo: Viviendas de uso turístico y plataformas virtuales
2016
La llamada economía colaborativa, fenómeno innovador de alcance global y transversal, supone la apuesta por una alternativa a las prácticas hasta ahora conocidas en nuestra sociedad de consumo. Esta idea de la economía colaborativa ha tenido una gran repercusión más allá de su incidencia en los mercados de servicios y bienes, afectando de forma directa al sector del alojamiento turístico. De hecho, se han generalizado de forma extraordinaria diferentes alternativas al alojamiento vacacional más tradicional, mediante plataformas virtuales que ofrecen viviendas privadas para su uso turístico a precios competitivos y prometen experiencias más cercanas a la convivencia vecinal que turística. An…
