    The objective of this work is to deepen in the relationships between the andalusian productive system and the water consumption. We will use an Impact Analysis and the Extraction Method. The first one allows us to study how it would affect to the regional water consumption a change in the sectorial demand. The second one allows us to simulate how it would affect to the water consumption the hypothetical extraction of a certain sector of the economic system. This study allows us to conclude that a reduction in the exports of some sectors would affect positively on the water saving; and that the extraction, fundamentally of the agro-alimentary industry, would considerably reduce the consumption of this resource. Before this reality we raised the possibility of considering a structural change in the region that consists of a productive specialization less water consumer.Input-Output analysis, Water consumption, Andalusian

    Analyzing Intersectorial Water Relationships by means of Graph Theory

    The aim of this work is to demonstrate the relationships between an economy’s productive sectors and the water consumption generated during productive processes. We shall study the andalusian reality, a region of southern Spain characterized by water scarcity, and we will examine whether excessive dependence on water resources which, may occur in some productive sectors, might affect not only the conservation and quality of this resource, but also have negative effects upon the solidity of the economy itself. A mixed methodology has been used, combining an Input-Output model with Graph Theory. We obtain a water Input-Output model and an intersectorial relationship matrix which is analysed by Graph Theory. Next, of a brief form, we developed to the model of water consumption and the graph most significant derivative of the water matrix. Our most important aim is to obtain the Intersectorial Water Relationships Matrix with an Input-Output model. This matrix, with order (nxn) and expressed in terms of water, represents all of the transactions which occur in the economy between the various productive sectors. Interesting conclusions can be drawn from this study, the most useful of which are the use of a mixed applied methodology and the conclusions to be drawn from the study in terms of economic policy. First, the suitability methodology’s for the proposed ends has to be reiterated. This mixed methodology, combining the extended Input-Output model with the Graph Theory, has been shown to be an appropriate method for analysing the relationships established between the productive structure and the consumption of natural resources since it allows direct and indirect relationships to be established. Another relevant conclusion is that there are sectors with a high level of water consumption which are hardly ever regarded as having high consumption. This is reference to the food processing industry, construction, textiles and clothing and restaurants and hotels. Although it is true that these industries are not noteworthy direct consumers, they are large indirect consumers, their demand contributing to the scarcity of water in Andalusia and creating a situation of dependency on the resource which could even perhaps endanger the stability of the economy itself. It is important that politicians in positions of power take these sectors’ high indirect consumption into account and regard not just the agricultural sectors as large water consumers. Finally, the main conclusion is that Andalusia's economic specialisation does not make a positive contribution towards water conservation and, moreover, that the regional economy's sustainability may be seriously endangered if the authorities do not take into account water limitations in their policy

    La configuración del ethos en los parágrafos V a XIX del libro I de El asno de oro de Apuleyo

    La finalidad de este artículo es el análisis del ethos de los personajes que actúan como narradores en los parágrafos V al XIX del Libro I del Asno de oro. Cabe aclarar que el estudio del ethos de los oradores se hace partiendo de la concepción de que el mismo es el resultado de una elaboración prediscursiva, que tendrá por resultado la construcción del ethos en el discurso retórico, concepto ya expresado por Aristóteles en su Retórica y retomado por las teorías del discurso y de la argumentación a partir de la segunda mitad del s. XX. Por lo tanto, la metodología a utilizar se vale tanto de obras de Retórica Clásica como de la Nueva Retórica. Además, se sirve de enfoques de la Lingüística y la Narratología. Por ser la novela de Apuleyo un ejemplo de lo que Bajtin denomina “dialogismo y alteridad", un segundo objetivo es el estudio de las relaciones que se establecen en el discurso de los personajes para tratar de determinar el sentido buscado en la obra y, en consecuencia, la incumbencia o verosimilitud de estos relatos en la misma.The purpose of this article is the analysis of the ethos of the characters that act as narrators in paragraphs V to X IX of Book I of The Golden Ass. It should be noted that the study of the ethos of the speakers is based on the conception that it is the result of a pre-discursive elaboration, which will result in the construction of ethos in rhetorical discourse, a concept already expressed by Aristotle in his Rhetoric and taken up by the theories of discourse and argumentation from the second half of the 20th century. Therefore, the methodology to be used is worth as much of works of Classical Rhetoric as of the New Rhetoric. In addition, it uses approaches to Linguistics and Narratology. Because Apuleyo's novel is an example of what Bakhtin calis "dialogism and alterity," a second objective is the study of the relationships established in the discourse of the characters to try to establish the meaning sought in the work, and in consequence the incumbency or verisimilitude of these stories in it.Fil: Alonso, Griselda Esther.

    Error estimators for a mixed method

    We present two a-posteriori error estimators for elliptic partial differential equations, when we use a mixed method. One is based on a adequate evaluation of the residual of the finite element solution and the other on the solution of a local problem. We prove their equivalence with the norm of the error, when the data is locally smooth.Facultad de Ciencias Exacta

    Modelo Input-Output de Agua. Análisis de las relaciones intersectoriales de agua en Andalucía

    Get PDF
    The aim of this work is to demonstrate the relationships between an economy’s productive sectors and the water consumption generated during productive processes. The methodology used is a water input-output model. We obtain this model combining the Leontief’s model and the Proops’ energy model. We study the andalusian reality, a region of southern Spain characterized by water scarcity, and we will examine whether excessive dependence on water resources which, may occur in some productive sectors, might affect not only the conservation and quality of this resource, but also have negative effects upon the solidity of the economy itself. In other words, we tried to detect the sectors that more amount of water consume, direct and indirect form, and we analyse if this factor could limit the economic growth of the region. This model allow us to distinguish between direct and indirect water consumption and this difference can be used like a factor of saved water policy. In the same way, the model permit us to make simulations in order to determinate the new level of consume when a rule is applied and its consequences on regional economy.Input-Output Model, Water consumption
