Taxation of nuclear waste in Spain

Law 15/2012 established in Spain four new environmental taxes and extended the scope objective excise duties on mineral oils to tax the use of natural gas and coal as sources of electricity. One of the newly created taxes falls on all electric power producers, and has as tax base the turnover. The second one tax hydropower production, and the other two fall on the nuclear industry. So, there are two new taxes in Spain on the production of electricity from nuclear sources. The first one is a tax on nuclear waste production; the second one is a tax on the storage of nuclear waste. However, these are not the only levies in the Spanish tax system affecting nuclear waste. At the State level there are already several charges on nuclear waste. At the regional level, on the other hand, two Autonomous Communities were taxing nuclear waste. The creation of these new State taxes will finish with the regional taxes, but the State will be oblige to compensate these regions for losing revenues. The purpose of this work is to carry out a critical analysis of the Spanish system of taxation on nuclear waste.

Principals barreres i motivacions per a la pràctica de l’activitat física de la població de 17 a 25 anys, a la localitat de Cardedeu

Actualment hi ha multitud d’estudis científics que demostren els beneficis que aporta a la nostra salut la pràctica regular d’activitat física, però aquest fet no genera per si sol uns nivells de pràctica suficients en la població. El present estudi s’emmarca en una investigació realitzada amb nois i noies d’entre 17 i 25 anys de la localitat de Cardedeu, sobre les diferents barreres i motivacions per a la pràctica d’activitat física de forma regular en aquest sector concret de la població. S’han analitzat els resultats obtinguts en l’aplicació dels qüestionaris ABPEF (Capdevila, 2005) i AMPEF (Capdevila, 2000) sobre una mostra formada per un total de 38 participants. En els resultats obtinguts destaquen les barreres relacionades amb la fatiga, la mandra, les obligacions i la falta de temps. Amb referència a motivacions més significatives trobem aquells ítems relacionats amb la salut, la imatge corporal, la diversió i el benestar.

Nutritional and feeding ecology in the Cory"s shearwater (Calonectris diomedea).

In birds, parents adjust their feeding behaviour according to breeding duties, which ultimately may lead to seasonal adjustments in nutritional physiology and hematology over the breeding season. Although avian physiology has been widely investigated in captivity, few studies have integrated individual changes in feeding and physiological ecology throughout the breeding season in wild birds. To study relationships between feeding ecology and nutritional ecophysiology in Cory"s shearwater Calonectris diomedea, we weighed and took blood samples from 28 males and 19 females during the pre-laying, egg-laying, incubation, hatching and chick-rearing periods of the breeding season. In addition, we fitted 6 birds with geolocators to track their foraging movements throughout the reproductive period. Thus, we examined individual changes in (1) nutritional condition (biochemistry metabolites); (2) oxygen carrying capacity (hematology); and (3) feeding areas and foraging effort (stable isotopes and foraging movements). Geolocators revealed a latitudinal shift in main feeding areas towards more southern and more neritic waters throughout the breeding season, which is consistent with the steady increase in δ13C signatures in the blood. Geolocators also showed a decrease in foraging effort from egg-laying to hatching, reflecting the activity decrease associated with incubation duties. Plasma metabolites, body mass and oxygen carrying capacity were associated with temporal changes in nutritional state and foraging effort in relation to recovery after migration, egg formation, fasting shifts during incubation and chick provisioning. This study shows that combining physiological and ecological approaches can help us understand the influence of breeding duties on feeding ecology and nutritional physiology in wild birds.

Afrontamiento de situaciones de hostilidad y desempeño de la función directiva. Planteamientos y reflexiones a raíz de una actividad de formación permanente de directivos de centros educativos de titularidad pública

The intervention in the organized conflicts and, particularly, the confrontation of hostile situations (based on the emotional alteration, the strain, the verbal aggressiveness, etc) is one of the aspects that worry the principals of the educative centres and, therefore, a main attention must be given to the initial and permanent training to have managing duties. Throughout the text we take some aspects into account in the development of these managing skills:a) we set the distinctive features; b) we answer to the dilemma about the existence of improvement possibilities; c) we state the need to star from the motivation and the active participation of the principals in their own personal development and, finally, d) we contribute with the design of a training activity to develop skills to confront hostile situations, addressed to the principals of primary and secondary schools, that was done in Girona, in November 2005

De More a Moore : de la utopia al cos, i a l’inrevés

Through the graphic novel V for Vendetta by Alan Moore and David Lloyd, I problematize here the act of classification of the subgenres within each genre. This is a literary study that aims to reflect on the utopian genre. It is a genre which requires in order to be understood a consideration of society and its organization. The concept of society cannot be properly discussed without mentioning the surface on which it is based: people with their selves and their bodies. Institutions and conventions act subtly and constantly on us, offering more or less free roles, usually related to a particular physical appearance, as may be the mode of dress, or gesture- and generating a negotiation between our desires and our duties. In other words, they act on us to transform us into people suitable for the smooth running of the community

A Fair and Secure Cluster Formation Process for Ad Hoc Networks

An efficient approach for organizing large ad hoc networks is to divide the nodesinto multiple clusters and designate, for each cluster, a clusterhead which is responsible forholding intercluster control information. The role of a clusterhead entails rights and duties.On the one hand, it has a dominant position in front of the others because it manages theconnectivity and has access to other node¿s sensitive information. But on the other hand, theclusterhead role also has some associated costs. Hence, in order to prevent malicious nodesfrom taking control of the group in a fraudulent way and avoid selfish attacks from suitablenodes, the clusterhead needs to be elected in a secure way. In this paper we present a novelsolution that guarantees the clusterhead is elected in a cheat-proof manner.
