Past and current distribution of Charaxes jasius jasius (Linnaeus, 1767) (Lepidoptera Nymphalidae) in Sicily in relation to its host plant, Arbutus u…
2022
The authors provide an updated overview of the past and present regional distribution of the two-tailed Pasha Charaxes jasius jasius (Linnaeus, 1767) (Lepidoptera Nymphalidae) and its host plant, the strawberry tree Arbutus unedo L. Most of the occurrence data reported in the entomological literature was confirmed, and several new populations have been recently dis- covered. The distribution pattern of the insect and its host plant overlap almost perfectly. C. jasius jasius is more abundant and forms large and stable populations on the Peloritani Mts. and in some areas of the Madonie Mountains. The high number of new records of C. jasius jasius suggests that the species is experiencing a sp…
Understanding tungsten erosion during inter/intra-ELM periods in He-dominated JET-ILW plasmas
2021
Tungsten erosion was quantified during inter/intra-ELM periods in He-dominated JET-ILW plasmas by optical emission spectroscopy. The intra-ELM tungsten sputtering in helium plasmas, which dominates the total W source, prevails by a factor of about 4 over inter-ELM sputtering in the investigated ELM frequency range from 90 Hz-120 Hz. He ions are mainly responsible for the W erosion during the ELMs in He plasmas. The strong in/out asymmetry of the ELM-induced W erosion is observed in He plasmas even at high ELM frequencies beyond 100 Hz. In Ohmic/L-mode plasmas and during the H-mode inter-ELM plasma phases both He2+ and Be2+ ionic species are major contributors to the W erosion. Their contrib…
Experimental Evolution Reveals a Genetic Basis for Membrane-Associated Virus Release
2021
Many animal viruses replicate and are released from cells in close association to membranes. However, whether this is a passive process or is controlled by the virus remains poorly understood. Importantly, the genetic basis and evolvability of membrane-associated viral shedding have not been investigated. To address this, we performed a directed evolution experiment using coxsackievirus B3, a model enterovirus, in which we repeatedly selected the free-virion or the fast-sedimenting membrane-associated viral subpopulations. The virus responded to this selection regime by reproducibly fixing a series of mutations that altered the extent of membrane-associated viral shedding, as revealed by fu…
“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…

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 …
Enhancing upper secondary students’ engagement and learning through the INTERACT online, video-based teacher coaching intervention : Protocol for a m…
2022
This protocol outlines a mixed-methods cluster randomized controlled trial (CRCT) in upper secondary schools that will investigate how video-based online coaching can support teachers’ competences in teacher-student interactions (TSIs) and thereby improve student engagement and learning. The intervention will take place over a school year with at least 100 teachers and 2,000 of their students. During the implementation and one-year follow-up, we will conduct an extensive implementation and process evaluation (IPE) to understand the intervention's effects on TSI and student engagement and learning outcomes. This protocol outlines the background, design, intervention, and primary and secondar…
Augmented reality as news
2021
If you are building complex, expensive VR today for the limited number of people, who get VR headsets, and [are] willing to scratch up on their heads to have the experience, experimentation is great, nice, but […] I think augmented reality is actually more interesting and has more potential for news. peerReviewed
