Los domos graníticos de la Cuenca del Ridaura (Girona)

Se describen los domos graníticos de la cuenca del río Ridaura. Sus caraterísticas geométricas se relacionan estrechamente con la disposición de las fracturas. Su génesis deriva de una fase subsuperficial, bajo un manto de alteración, presumiblemente desarrollada durante el Plioceno, y una fase de exhumación torrencial, que comprende desde el Plioceno terminal hasta la actualidad

Impacto ambiental previsto en la explotación de gravas en la zona de concurso medio del riu Fluvià (Girona)

The main environmental impacts related to the gravel pits in the medium course of the Fluvià river have been assessed. In order to compute the global impact and index based on the numerical values of different impacts has been defined. This index is applied to different areas and the results reveal that the environmental impact expected for a gravel pit is high or moderate close to the main streams and low in the rest of the territory

Geología ecológica, geodiversidad, geoconservación y Patrimonio Geológico de la Declaración de Girona

This work presents a new way of understanding the geological science: the Ecological Geology. It is based on the clasical vision of the Geology as well as on some new concepts, as Geodiversity and Geoconservation. An aplication of these perspective to the Geological Heritage is also included, in a list of ten points, called Declaración de Girona, because it is concibed in this city

How universal is behavior? A four country comparison of spite, cooperation and errors in voluntary contribution mechanisms

This paper studies behavior in experiments with a linear voluntary contributions mechanism for public goods conducted in Japan, the Netherlands, Spain and the USA. The same experimental design was used in the four countries. Our 'contribution function' design allows us to obtain a view of subjects' behavior from two complementary points of view. If yields information about situations where, in purely pecuniary terms, it is a dominant strategy to contribute all the endowment and about situations where it is a dominant strategy to contribute nothing. Our results show, first, that differences in behavior across countries are minor. We find that when people play "the same game" they behave similarly. Second, for all four countries our data are inconsistent with the explanation that subjects contribute only out of confusion. A common cooperative motivation is needed to explain the date.

On the stability of cooperation structures

Qin [J. Eco. Th., 1996] recently showed that in a game of endogenous formation of cooperation structure, if the underlying TU-game is superadditive, then the full cooperation structure is stable. In this note, we characterize the class of games that ensure the stability of the full cooperation structure, and show that this class is much larger than that of superadditive TU-games.

Firm strategies in R&D: cooperation and participation in R&D programs

This paper presents empirical evidence on firms’ decisions to cooperate in R&D and the extent to which government sponsored R&D programs increase cooperation. Using a sample of firms from the Spanish innovation survey we jointly estimate the determinants of firm participation in R&D programs and of choice of cooperation partners. We find that (i) firms participating in national and European programs have different profiles, suggesting program complementarity; (ii) private-private and publicprivate cooperation are associated on average with firms with different characteristics, and (iii) national R&D programs seem to have a positive effect on all types of cooperation, but especially on public-private partnerships.

Milk, from medicine to food Mediterranean Europe: Catalonia, 19th-20th centuries

The spread of milk consumption was a significant change in the diet of Europeans, however it is one that has not been greatly studied with regard to the populations of Mediterranean Europe. In this article we shall analyse the ain circumstances that conditioned that process in Catalonia between the middle of the 19th century and 1936. In our study we shall argue that the consumption of milk in this area was only relevant in the 19th century in situations of illness or old age, and that it subsequently increased and acquired a new significance as a result of various factors. In particular, we shall emphasise: (a) the scientific advances in microbiology and nutrition, (b) the activities carried out by doctors and various public institutions to promote the consumption of fresh milk, and (c) the technological innovations in the milk producing sector. In Appendix 1 we show two maps representing the main territorial references that we shall mention.
