Durant els darrers anys hem assistit a una ampliació de la perspectiva a través de la qual han estat observades les imatges. Entre els historiadors de l'art, les preguntes tradicionals, centrades en l'autoria o en la seva dimensió estètica, han passat a compartir l'interès amb altres qüestions com ara la del comitent i el seu entorn, la circulació, el mercat o els múltiples usos i significats que aquelles podien adquirir.

[cat] Aquest article intenta reconstruir la història de quatre pintures de l'artista napolità Andrea Vaccaro, actualment al Museu Nacional d'Art de Catalunya, i originàriament part d'una sèrie de 12 peces dedicada a les històries bíbliques de Tobies, propietat del virrei de Nàpols Pedro Antonio de Aragón. L'anàlisi de les obres i del context de la seva comissió a la llum d'estudis recents permet corregir-ne la datació i comprendre la importància de les quatre peces de Vaccaro del MNAC, en el marc de la circulació d'obres d'art entre el Regne de Nàpols i la península Ibèrica al llarg del segle XVII.

L'article 122 de l'Estatut d'autonomia de Catalunya (EAC) reconeix a la Generalitat la competència exclusiva per a establir el règim jurídic, les modalitats, el procediment, l'acompliment i la convocatòria per la mateixa Generalitat o pels ens locals, en l'àmbit de llurs competències, d'enquestes, audiències públiques,formes de participació i qualsevol altre instrument de consultes populars, salvant el que disposa l'article 149.1.32 de la Constitució espanyola (CE). La STC 31/2010, de 20 de juny, avala al seu fonament jurídic 69, la constitucionalitat del precepte estatutari, però amb una interpretació marcadament restrictiva.

Amb aquest projecte d'intervenció ens agradaria poder posar sobre la taula que l'art teràpia és una disciplina, una tècnica dins de la psicologia, que aporta beneficis psico-emocionals als usuaris que la reben; en el cas d'aquest projecte amb nens i adolescents amb càncer a l'Hospital Sant Joan de Déu.

Organic food products are highly susceptible to fraud. Currently, administrative controls are conducted to detect fraud, but having an analytical tool able to verify the organic identity of food would be very supportive. The state-of-the-art in food authentication relies on fingerprinting approaches that find characteristic analytical patterns to unequivocally identify authentic products. While wide research on authentication has been conducted for other commodities, the authentication of organic chicken products is still in its infancy. Challenges include finding fingerprints to discriminate organic from conventional products, and recruiting sample sets that cover natural variability. Future research might be oriented towards developing new authentication models for organic feed, eggs and chicken meat, keeping models updated and implementing them into regulations. Meanwhile, these models might be very supportive to the administrative controls directing inspections towards suspicious fraudulent samples.

We adapt the Shout and Act algorithm to Digital Objects Preservation where agents explore file systems looking for digital objects to be preserved (victims). When they find something they “shout” so that agent mates can hear it. The louder the shout, the urgent or most important the finding is. Louder shouts can also refer to closeness. We perform several experiments to show that this system works very scalably, showing that heterogeneous teams of agents outperform homogeneous ones over a wide range of tasks complexity. The target at-risk documents are MS Office documents (including an RTF file) with Excel content or in Excel format. Thus, an interesting conclusion from the experiments is that fewer heterogeneous (varying skills) agents can equal the performance of many homogeneous (combined super-skilled) agents, implying significant performance increases with lower overall cost growth. Our results impact the design of Digital Objects Preservation teams: a properly designed combination of heterogeneous teams is cheaper and more scalable when confronted with uncertain maps of digital objects that need to be preserved. A cost pyramid is proposed for engineers to use for modeling the most effective agent combinations

As wireless communications evolve towards heterogeneousnetworks, mobile terminals have been enabled tohandover seamlessly from one network to another. At the sametime, the continuous increase in the terminal power consumptionhas resulted in an ever-decreasing battery lifetime. To that end,the network selection is expected to play a key role on howto minimize the energy consumption, and thus to extend theterminal lifetime. Hitherto, terminals select the network thatprovides the highest received power. However, it has been provedthat this solution does not provide the highest energy efficiency.Thus, this paper proposes an energy efficient vertical handoveralgorithm that selects the most energy efficient network thatminimizes the uplink power consumption. The performance of theproposed algorithm is evaluated through extensive simulationsand it is shown to achieve high energy efficiency gains comparedto the conventional approach.

This article deals with electrocatalysis and electrocatalysts for low temperature fuel cells and also with established means and methods in electrocatalyst research, development and characterization. The intention is to inform about the fundamentals, state of the art, research and development of noble metal electrocatalysts for fuel cells operating at low temperatures.
