Alteration-Induced Volcano Instability at La Soufrière de Guadeloupe (Eastern Caribbean)
2021
International audience; Volcanoes are unstable structures that deform laterally and frequently experience mass wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes significantly to volcano instability. We present a study that combines laboratory experiments, geophysical data, and large-scale numerical modeling to better understand the influence of alteration on volcano stability, using La Soufrière de Guadeloupe (Eastern Caribbean) as a case study. Laboratory experiments on variably altered (advanced argillic alteration) blocks show that uniaxial compressive strength, Young's modulus, and cohesion decrease as a function of increasing alteration, but that …
Il ri-ciclo socialmente innovativo come attivatore di sviluppo urbano e regionale. I brownfield come contesto di analisi e azione.
The research topic is the re-cycling of brownfields with social innovative practices, and how it can activate the urban and regional development. The research analyses critically and interprets the re-cycle theory (Marini and Bocchi 2014; Carta 2014) developed by the Italian Research “Re-cycle Italy” (PRIN) focusing on its social innovative aspects (Moulaert et al., 2005; Phills et al., 2008, Tekin and Tekdogan, 2015). Nowadays, the community-based planning is essential for the spatial regeneration processes. These realities generate a new sense of consciousness and a huge network of local activists, social enterprises able to develop the place in an incremental way. Therefore, it is import…
La contestación a los próceres. Pugna de facciones y desórdenes en Valencia (1376-1478)
2021
La intermitencia de los ataques verbales y escritos contra las decisiones de gobierno de la ciudad de Valencia a lo largo de un siglo se inscriben en una dinámica absorbente, liderada por partidos rivales de la oligarquía, capaces éstos de asumir reivindicaciones grupales ajenas y de arrastrar a parte de los ciudadanos y de los menestrales bajo fórmulas clientelares. Las circunstancias concretas de las protestas superaron los cauces institucionales previstos en una asamblea municipal renovada anualmente y con amplia representación social, la cual se demostró más como plataforma para la adhesión de los vecinos respecto a los líderes de la sociedad política y menos como órgano de discusión po…
“Palermo liquida. Il progetto per il waterfront come occasione di rigenerazione della città”
2011
Il progetto di riqualificazione del Waterfront di Palermo è parte di una politica nazionale più ampia: il PIAU “Porti e Stazioni”, finanziato dal Ministero delle Infrastrutture, con la collaborazione attiva del Comune, dell'Autorità Portuale e delle Ferrovie. Il nuovo “Piano regolatore portuale” (PRP), oltre ad affrontare le questioni più generali delle funzioni portuali, propone strategie per affrontare la questione della “ aree di interazione città-porto” e le "aree di interfaccia", immaginate per accogliere nuove funzioni residenziali, commerciali, culturali e ricreative. Il paper attraverso la descrizione del progetto per il waterfront di Palermo e il processo di redazione del nuovo PRP…
Connectivity of urban rivers and environmental justice
2018
With the explosion of urban waterfront revitalization projects in the developed world, it is timely to reflect on the relations between cities and their rivers: how the rivers influenced development of the cities, how cities have treated their riverfronts since 19th century, and how the spatial relations of city and river constrain and enable improved connectivity between urban populations and their rivers. Both celebrated as revitalizing neglected urban centers and criticized for displacing the disenfranchised populations, riverfront revitalization projects raise questions about what constitutes ‘restoration’ in cities, to what degree natural processes and ecological values can be restored…

Multimetallic Oxynitrides Nanoparticles for a New Generation of Photocatalysts
2019
A versatile synthetic strategy for the preparation of multimetallic oxynitrides has been designed and here exemplarily discussed considering the preparation of nanoscaled zinc-gallium oxynitrides and zinc-gallium-indium oxynitrides, two important photocatalysts of new generation, which proved to be active in key energy related processes from pollutant decomposition to overall water splitting. The synthesis presented here allows the preparation of small nanoparticles (less than 20 nm in average diameter), well-defined in size and shape, yet highly crystalline and with the highest surface area reported so far (up to 80 m2 g-1 ). X-ray diffraction studies show that the final material is not a…
Aceptación del pago móvil en España: análisis de la conveniencia y la usabilidad en el contexto de una batalla generacional
2017
Entender la aceptación y el uso de una nueva tecnología constituye una de las corrientes más maduras y fructíferas de investigación dentro de los sistemas de información. Contar con un modelo que maximice el poder explicativo sin perder de vista el contexto de utilización y las características de los usuarios, se ha transformado en un imperativo. El propósito central de la investigación propuesta consiste en presentar y contrastar un modelo holístico de síntesis de aceptación voluntaria de una tecnología, por parte de un consumidor individual. Este modelo integrará distintas perspectivas, aplicadas a la adopción del servicio de pago móvil. Asimismo, se analizará el impacto de la brecha gene…
Cognition Is Not What It Used to Be: Reconsidering Usability From an Embodied Embedded Cognition Perspective
2009
Embodied embedded cognition (EEC) has gained support in cognitive science as well as in human–computer interaction (HCI). EEC can be characterized both by its action-centeredness as well as its roots in phenomenology. The phenomenological aspects of EEC could be seen as support for trends in design emphasizing the user experience. Meanwhile, usability issues often are still approached using traditional methods based on cognitivist assumptions. In this paper, I argue for a renewed focus on improving usability from an EEC perspective. I draw mainly on a behavior-oriented interpretation of the theory, the key aspects of which are reviewed. A tentative sketch for an embodied embedded usability …
