Environmental conflicts, environmental justice and valuation

In this article some historical and contemporary environmental conflicts are described. The international environmental liability of mining corporations is discussed. Comparisons are made with conflicts in the United States and in South Africa which fall under the rubric of the Environmental Justice movement. Such conflicts are fought out in many languages, and the economic valuation of damages is only one of such languages. Who has the power to impose particular languages of valuation? Who rules over the ways and means of simplifying complexity, deciding that some points of view are out of order? Who has power to determine which is the bottom-line in an environmental discussion?

El Rossinyol torna de França : La realitat del cant coral al tombant del segle XXI

Estudi del moviment coral a Catalunya des d'un punt de vista antropològic i social. Fa èmfasi en el paper dels repertoris del cant coral i en la manera com aquests repertoris reflecteixen la història social i cultural del món del cant coral a Catalunya. Estudi d'un microcosmos: l'Orfeó de les Corts, la seva trajectòria musical i la seva trajectòria com a entitat en els darrers 50 anys a Barcelona. S'analitza què hi ha més enllà del fet coral: el tipus de música, el fet de cantar en grup, els tipus d'associacions, la procedència, els objectius i la filosofia, les inquietuds dels cantaires i les preferències dels directors, per tal de copsar les dinàmiques socials i musicals del moviment coral.

A subsampling approach to estimating the distribution of diversing statistics with application to assessing financial market risks

In this paper we propose a subsampling estimator for the distribution ofstatistics diverging at either known rates when the underlying timeseries in strictly stationary abd strong mixing. Based on our results weprovide a detailed discussion how to estimate extreme order statisticswith dependent data and present two applications to assessing financialmarket risk. Our method performs well in estimating Value at Risk andprovides a superior alternative to Hill's estimator in operationalizingSafety First portofolio selection.

Use of nitrification inhibitor DMPP to improve nitrogen recovery in irrigated wheat on a calcareous soil

The 3,4-dimethyilpyirazole phosphate (DMPP), commercialized as Entec, is a nitrification inhibitor developed by BASF (Germany) that may help to minimize N losses and to obtain a higher profit from N fertilizers. A two-year field trial was established in 2001 in the Northeast of Spain to assess the effects of DMPP on N use efficiency (NUE) and to determine the economic returns. Seven treatments have been carried out comparing the effect of DMPP on pig slurry and on mineral fertilizers. The application of DMPP resulted in better efficiency indexes on mineral fertilizers. An apparent nitrogen recovery of 0.465 kg kg-1, on average, was obtained for the Entec treatment. A net benefit of € 809 ha-1, on average, was obtained for the Entec treatment compared with € 607 ha-1 for the control treatment. The results of this study suggest that the nitrification inhibitor could improve farmer profit in irrigated wheat on a calcareous soil.
