Tools to quantify environmental impact and their application to teaching: projects City-zen and HEREVEA

This article presents several strategies to teach university students and professionals in the sector how to reduce the environmental impact of our cities. Firstly, the European City- zen project is summarized and its application to the city of Seville, more specifically to Tirode Linea, a working class neighbourhood, is described; the viability and functionality of the neighbourhood are analyzed and improvements are proposed so that it can become an area that attains zero emissions. Secondly, the HEREVEA project is presented, which developed software for the feasibility analysis and proposals to improve neighbourhoods. Its usefulness is discussed in a case study carried out in the same neighbourhood. Finally, the experience of how to transmit all this knowledge through university teaching is presented

The sensitivity of binocular rivalry to changes in the nondominant stimulus

The nature of rivalry suppression was investigated by examining the effects of changing one of the rivalling stimuli at the beginning of its phases of suppression. The stimulus was an obliquelyoriented grating whose phase, spatial frequency and contrast could be changed without altering its mean luminance. Such changes were found to disturb the course of rivalry and, more specifically, to cause the reappearance of the stimulus within 20 msec. Suppression is thus shown to be selective and not to render the subject insensitive to all classes of stimulus change
