L'objecte del plet són els requisits necessaris per a la instal·lació d¿una xemeneia per a l'evacuació dels fums del local situat en els baixos d'un edifici en règim de propietat horitzontal. La matèria no és nova, però la STSJC de 31 de març de 2008 suposa un canvi de criteri jurisprudencial en relació amb la STSJC de 15 de gener de 2005, que la Sala ha de justificar per evitar la infracció del principi d¿igualtat en l¿aplicació de la llei.

This study examines whether math anxiety and negative attitudes toward mathematics have an effect on university students" academic achievement in a methodological course forming part of their degree. A total of 193 students were presented with a math anxiety test and some questions about their enjoyment, self-confidence and motivation regarding mathematics, and their responses were assessed in relation to the grades they had obtained during continuous assessment on a course entitled"Research Design". Results showed that low performance on the course was related to math anxiety and negative attitudes toward mathematics. We suggest that these factors may affect students" performance and should therefore be taken into account in attempts to improve students" learning processes in methodological courses of this kind.

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.

La STS, 1a, 21.11.2008, objeto de este comentario, plantea a un tiempo la responsabilidad del consumidor, vendedor, fabricante y Administración pública por los daños materiales causados por la explosión de un producto altamente inflamable que había sido vendido a un particular para la desinfección de su vivienda.

In this paper, a new algorithm for blind inversion of Wiener systems is presented. The algorithm is based on minimization of mutual information of the output samples. This minimization is done through a Minimization-Projection (MP) approach, using a nonparametric “gradient” of mutual information.
Abnormal Error Monitoring in Math-Anxious Individuals: Evidence from Error-Related Brain Potentials.
Resumo:
This study used event-related brain potentials to investigate whether math anxiety is related to abnormal error monitoring processing. Seventeen high math-anxious (HMA) and seventeen low math-anxious (LMA) individuals were presented with a numerical and a classical Stroop task. Groups did not differ in terms of trait or state anxiety. We found enhanced error-related negativity (ERN) in the HMA group when subjects committed an error on the numerical Stroop task, but not on the classical Stroop task. Groups did not differ in terms of the correct-related negativity component (CRN), the error positivity component (Pe), classical behavioral measures or post-error measures. The amplitude of the ERN was negatively related to participants" math anxiety scores, showing a more negative amplitude as the score increased. Moreover, using standardized low resolution electromagnetic tomography (sLORETA) we found greater activation of the insula in errors on a numerical task as compared to errors in a nonnumerical task only for the HMA group. The results were interpreted according to the motivational significance theory of the ERN.

This study uses event-related brain potentials (ERPs) to investigate the electrophysiological correlates of numeric conflict monitoring in math-anxious individuals, by analyzing whether math anxiety is related to abnormal processing in early conflict detection (as shown by the N450 component) and/or in a later, response-related stage of processing (as shown by the conflict sustained potential; Conflict-SP). Conflict adaptation effects were also studied by analyzing the effect of the previous trial"s congruence in current interference. To this end, 17 low math-anxious (LMA)and 17 high math-anxious (HMA) individuals were presented with a numerical Stroop task. Groups were extreme in math anxiety but did not differ in trait or state anxiety or in simple math ability. The interference effect of the current trial (incongruent-congruent) and the interference effect preceded by congruence and by incongruity were analyzed both for behavioral measures and for ERPs. A greater interference effect was found for response times in the HMA group than in the LMA one. Regarding ERPs, the LMA group showed a greater N450 component for the interference effect preceded by congruence than when preceded by incongruity, while the HMA group showed greater Conflict-SP amplitude for the interference effect preceded by congruence than when preceded by incongruity. Our study showed that the electrophysiological correlates of numeric interference in HMA individuals comprise the absence of a conflict adaptation effect in the first stage of conflict processing (N450) and an abnormal subsequent up-regulation of cognitive control in order to overcome the conflict (Conflict-SP). More concretely, our study shows that math anxiety is related to a reactive and compensatory recruitment of control resources that is implemented only when previously exposed to a stimuli presenting conflicting information
