Visions i aparences del mite de Tristany i Isolda

Treball de recerca realitzat per un grup d’alumnes d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2006."Tristany i Isolda" representa un dels grans mites eròtics moderns. A través de les diferents versions de les fonts medievals i de les més contemporànies més estimades per melòmans, Wagner i Bédier, es defineixen semblances i diferències i els trets principals dels personatges, arguments, espais... L'estudi d'aquestes obres constata que la finalitat de tots els creadors era, almenys a efectes interpretatius, la mateixa. És evident que tant Tomàs com Wagner intentaven plasmar les alegries i els sofriments dels eterns amants, però potser per influència de Plató mostren un procés catàrtic i redemptor de dos individus a través de l'amor que es converteix en una via cap a un eixamplament tan enorme de la consciència que no pot desembocar sinó en la mort, el punt en què dos amants es converteixen en un únic alè, el punt en què dos éssers satisfacin individualment els seus anhels de felicitat col•lectiva. Partint d'aquesta idea, com el lector comprovarà a les conclusions, es pot sostenir la tesi que aquest tipus de relació en què l'anhel de saviesa vital és tan exacerbat es correspon generalment amb una actitud lesbiana. I és que, perifrasejant Wagner, tot rau en aprendre a morir.

Green vs. Lempert functions: a minimal example

The Lempert function for a set of poles in a domain of Cn at a point z is obtained by taking a certain infimum over all analytic disks going through the poles and the point z, and majorizes the corresponding multi-pole pluricomplex Green function. Coman proved that both coincide in the case of sets of two poles in the unit ball. We give an example of a set of three poles in the unit ball where this equality fails.

Evaluation of subsidies programs to sell green cars: Impact on prices, quantities and efficiency

During the recent period of economic crisis, many countries have introduced scrappage schemes to boost the sale and production of vehicles, particularly of vehicles designed to pollute less. In this paper, we analyze the impact of a particular scheme in Spain (Plan2000E) on vehicle prices and sales figures as well as on the reduction of polluting emissions from vehicles on the road. We considered the introduction of this scheme an exogenous policy change and because we could distinguish a control group (non-subsidized vehicles) and a treatment group (subsidized vehicles), before and after the introduction of the Plan, we were able to carry out our analysis as a quasi-natural experiment. Our study reveals that manufacturers increased vehicle prices by the same amount they were granted through the Plan (1,000 €). In terms of sales, econometric estimations revealed an increase of almost 5% as a result of the implementation of the Plan. With regard to environmental efficiency, we compared the costs (inverted quantity of money) and the benefits of the program (reductions in polluting emissions and additional fiscal revenues) and found that the Plan would only be beneficial if it boosted demand by at least 30%.

L'antic Egipte a la Bíblia : el mite d'Egipte en les fonts de l'Antic Testament entre alteritat negativa i paradís d'acollida

El treball presenta un estudi de la Història Antiga d'Israel i Egipte, des d'una perspectiva relativament poc tractada. No proposa estudiar Israel ni Egipte, sinó allò que pensaven els autors bíblics sobre Egipte.

Perspectives on the green construction of the new European Energy Policy

The EU has been one of the main actors involved in the construction process of an international climate change regime, adopting it as an identity sign in the international arena. This activism has reverted in the European political agenda and in the one of its Members States. Therefore, climate change has become a driver for the EU growing participation in energy policy and for its governance evolution. In this context, much attention has been paid to the climate and energy policies integration agreed after the 2007 spring European Council. Apparently, this decision meant a decisive step towards the incorporation of the environmental variable in the energy policy-making. Moreover, the Action Plan [2007-2009] “Energy Policy for Europe” outlined priority actions in a variety of energy-related areas, implying the new European Energy Policy commencement. Against this background, there is still much left to understand about its formulation and its further development. Rooted on the Environmental Policy Integration approach, this paper traces the increasing proximity between environment and energy policies in order to understand the green contribution to the European Energy Policy construction.

The adverse effects of environmental policy in green markets

We model green markets in which purchasers, either firms orconsumers, have higher willingness-to-pay for lesspolluting goods. The effectiveness of pollution reductionpolicies is examined in a duopoly setting. We show thatduopolists' strategic behaviour may increase pollutionlevels. Maximum emission standards, commonly used in greenmarkets, improve the environmental features of products.Nonetheless, overall pollution levels will rise becausegovernment regulation also affects market shares and bootsfirms' sales. Consequently, social welfare may be reduced.We also explore the effects of technological subsidies andproduct charges, including differentiation of charges.

Dona, endevinació i mite a l’antiga Grècia

El plantejament de fer un treball final en la modalitat acadèmica permet a l’estudiant d’aprofundir en algun aspecte acadèmic que li hagi semblat interessant i del que cregui no tenir gaire o suficients coneixements. Aquest és el meu cas. En el segon any del màster vaig cursar l’assignatura Elaboracions del mite, impartida per l’Emilio Suárez, que em va permetre accedir a l’antiga Grècia amb una àmplia panoràmica que abraçava la mitologia des de diferents fonts —arqueològiques i textuals—, la història i la literatura. Si bé la majoria d’assignatures que he cursat s’han centrat —casualment— en les arts de finals del segle XIX i principis del XX, les referències a la cultura antiga han sigut constants en el màster i aquesta perseverança és el motiuque em va conduir cap a un tema que mirés cap aquest passat llunyà que, tanmateix, gaudeix de la reminiscència pròpia de qualsevol llegat.

Intense green-yellow electroluminescence from Tb+-implanted silicon-rich silicon nitride/oxide light emitting devices

High optical power density of 0.5 mW/cm2, external quantum efficiency of 0.1%, and population inversion of 7% are reported from Tb+-implanted silicon-rich silicon nitride/oxide light emitting devices. Electrical and electroluminescence mechanisms in these devices were investigated. The excitation cross section for the 543 nm Tb3+ emission was estimated under electrical pumping, resulting in a value of 8.2 × 10−14 cm2, which is one order of magnitude larger than one reported for Tb3+:SiO2 light emitting devices. These results demonstrate the potentiality of Tb+-implanted silicon nitride material for the development of integrated light sources compatible with Si technology.

Binding energy and momentum distribution of nuclear matter using Green's functions methods

The influence of hole-hole (h-h) propagation in addition to the conventional particle-particle (p-p) propagation, on the energy per particle and the momentum distribution is investigated for the v2 central interaction which is derived from Reid¿s soft-core potential. The results are compared to Brueckner-Hartree-Fock calculations with a continuous choice for the single-particle (SP) spectrum. Calculation of the energy from a self-consistently determined SP spectrum leads to a lower saturation density. This result is not corroborated by calculating the energy from the hole spectral function, which is, however, not self-consistent. A generalization of previous calculations of the momentum distribution, based on a Goldstone diagram expansion, is introduced that allows the inclusion of h-h contributions to all orders. From this result an alternative calculation of the kinetic energy is obtained. In addition, a direct calculation of the potential energy is presented which is obtained from a solution of the ladder equation containing p-p and h-h propagation to all orders. These results can be considered as the contributions of selected Goldstone diagrams (including p-p and h-h terms on the same footing) to the kinetic and potential energy in which the SP energy is given by the quasiparticle energy. The results for the summation of Goldstone diagrams leads to a different momentum distribution than the one obtained from integrating the hole spectral function which in general gives less depletion of the Fermi sea. Various arguments, based partly on the results that are obtained, are put forward that a self-consistent determination of the spectral functions including the p-p and h-h ladder contributions (using a realistic interaction) will shed light on the question of nuclear saturation at a nonrelativistic level that is consistent with the observed depletion of SP orbitals in finite nuclei.
