Responsabilidad civil y daños a los propios bienes. Comentario a las SSTS, 1a, 29.10.2008 (RJ 2008\5801; MP: Román García Varela) y 22.12.2008 (RJ 2009\162; MP: Juan Antonio Xiol Ríos)

En 2008 y en dos ocasiones, la Sala Primera del Tribunal Supremo ha resuelto la cuestión relativa a si el propietario de una finca, la cual había contaminado como consecuencia del desarrollo de su actividad industrial y había vendido ocultando esta circunstancia, es responsable extracontractualmente frente al tercer adquirente por los daños económicos sufridos. En la primera Sentencia, de 29.10.2008, el Tribunal Supremo condena al contaminador por responsabilidad extracontractual. En la segunda, de 22.12.2008, el Tribunal Supremo absuelve a éste de la responsabilidad extracontracual porqué los daños fueron causados a una finca propia.

A Semantic wiki for quality management in software development projects

Quality management has become a strategic issue for organisations and is very valuable to produce quality software. However, quality management systems (QMS) are not easy to implement and maintain. The authors' experience shows the benefits of developing a QMS by first formalising it using semantic web ontologies and then putting them into practice through a semantic wiki. The QMS ontology that has been developed captures the core concepts of a traditional QMS and combines them with concepts coming from the MPIu'a development process model, which is geared towards obtaining usable and accessible software products. Then, the ontology semantics is directly put into play by a semantics-aware tool, the Semantic MediaWiki. The developed QMS tool is being used for 2 years by the GRIHO research group, where it has manages almost 50 software development projects taking into account the quality management issues. It has also been externally audited by a quality certification organisation. Its users are very satisfied with their daily work with the tool, which manages all the documents created during project development and also allows them to collaborate, thanks to the wiki features.

Building a usable and accessible semantic web interaction platform

Semantic Web applications take off is being slower than expected, at least with respect to “real-world” applications and users. One of the main reasons for this lack of adoption is that most Semantic Web user interfaces are still immature from the usability and accessibility points of view. This is due to the novelty of these technologies, but this also motivates the exploration of alternative interaction paradigms, different from the “traditional” Web or Desktop applications ones. Our proposal is realized in the Rhizomer platform, which explores the possibilities of the object–action interaction paradigm at the Web scale. This paradigm is well suited for heterogeneous resource spaces such as those common in the Semantic Web. Resources, described by metadata, correspond to the objects in the paradigm. Semantic web services, which are dynamically associated to these objects, correspond to the actions. The platform is being put into practice in the context of a research project in order to build an open application for media distribution based on Semantic Web technologies. Moreover, its usability and accessibility have been evaluated in this real setting and compared to similar systems.

Acotaciones a la traducción de clásicos grecolatinos y modernos de José María Valverde

Este trabajo es un comentario a un diálogo-entrevista con José María Valverde (Valencia de Alcántara/Cáceres/1926-Barcelona, 1996), en su vertiente estrictamente traductora. La importancia del comentario estriba en el hecho de que muchas traducciones del eximio teórico de la literatura, poeta y traductor extremeño servirán, con el tiempo, de modelo de lengua y cultura. De ahí la importancia de leer en su contexto, reseñar y comentar sus opiniones. Así, pues en el trabajo se reproducen y se comentan hasta seis items: 1. Para traducir bien, hay que oír al autor original. 2. El traductor tiene que vivir de su trabajo. 3. En Italia se traduce bien. 4. Está por escribir una historia del sentido del humor. 5. Cuando no existe una tradición hay que inventarla. 6. Lo primero es hablar; después traducir.

Detection of PrPres in genetically susceptible fetuses from sheep with natural scrapie

Scrapie is a transmissible spongiform encephalopathy with a wide PrPres dissemination in many non-neural tissues and with high levels of transmissibility within susceptible populations. Mechanisms of transmission are incompletely understood. It is generally assumed that it is horizontally transmitted by direct contact between animals or indirectly through the environment, where scrapie can remain infectious for years. In contrast, in utero vertical transmission has never been demonstrated and has rarely been studied. Recently, the use of the protein misfolding cyclic amplification technique (PMCA) has allowed prion detection in various tissues and excretions in which PrPres levels have been undetectable by traditional assays. The main goal of this study was to detect PrPres in fetal tissues and the amniotic fluid from natural scrapie infected ewes using the PMCA technique. Six fetuses from three infected pregnant ewes in an advanced clinical stage of the disease were included in the study. From each fetus, amniotic fluid, brain, spleen, ileo-cecal valve and retropharyngeal lymph node samples were collected and analyzed using Western blotting and PMCA. Although all samples were negative using Western blotting, PrPres was detected after in vitro amplification. Our results represent the first time the biochemical detection of prions in fetal tissues, suggesting that the in utero transmission of scrapie in natural infected sheep might be possible.

Task-induced deactivation from rest extends beyond the default mode brain network

Activity decreases, or deactivations, of midline and parietal cortical brain regions are routinely observed in human functional neuroimaging studies that compare periods of task-based cognitive performance with passive states, such as rest. It is now widely held that such task-induced deactivations index a highly organized"default-mode network" (DMN): a large-scale brain system whose discovery has had broad implications in the study of human brain function and behavior. In this work, we show that common task-induced deactivations from rest also occur outside of the DMN as a function of increased task demand. Fifty healthy adult subjects performed two distinct functional magnetic resonance imaging tasks that were designed to reliably map deactivations from a resting baseline. As primary findings, increases in task demand consistently modulated the regional anatomy of DMN deactivation. At high levels of task demand, robust deactivation was observed in non-DMN regions, most notably, the posterior insular cortex. Deactivation of this region was directly implicated in a performance-based analysis of experienced task difficulty. Together, these findings suggest that task-induced deactivations from rest are not limited to the DMN and extend to brain regions typically associated with integrative sensory and interoceptive processes.
