A día de hoy, nadie puede poner en duda el extraordinario desarrollo que las tecnologías de la comunicación y la comunicación (TIC) han experimentado en nuestras vidas. Y, aunque especialmente explotadas por el mundo empresarial, donde se obtienen rendimientos observables a corto plazo, las nuevas tecnologías (NNTT) se han introducido de lleno en la enseñanza: programas interactivos desde Internet, ordenadores interconectados mediante redes inalámbricas, cañones de datos y pizarras digitales forman parte del entorno académico, y suponen un valioso apoyo para los docentes

En este trabajo se pretende conseguir una plataforma que permita obtener información y acceder de forma lo más homogénea posible a recursos heterogéneos para poder extraer metadatos, con especial interés en los recursos geoespaciales. Este sería el primer paso para la descripción de los recursos, mediante la cual, posteriormente se podrá abordar la publicación, ya sea mediante la indexación respecto a sus características o la inclusión en un servidor de catálogo

Dynamic optimization methods have become increasingly important over the last years in economics. Within the dynamic optimization techniques employed, optimal control has emerged as the most powerful tool for the theoretical economic analysis. However, there is the need to advance further and take account that many dynamic economic processes are, in addition, dependent on some other parameter different than time. One can think of relaxing the assumption of a representative (homogeneous) agent in macro- and micro-economic applications allowing for heterogeneity among the agents. For instance, the optimal adaptation and diffusion of a new technology over time, may depend on the age of the person that adopted the new technology. Therefore, the economic models must take account of heterogeneity conditions within the dynamic framework. This thesis intends to accomplish two goals. The first goal is to analyze and revise existing environmental policies that focus on defining the optimal management of natural resources over time, by taking account of the heterogeneity of environmental conditions. Thus, the thesis makes a policy orientated contribution in the field of environmental policy by defining the necessary changes to transform an environmental policy based on the assumption of homogeneity into an environmental policy which takes account of heterogeneity. As a result the newly defined environmental policy will be more efficient and likely also politically more acceptable since it is tailored more specifically to the heterogeneous environmental conditions. Additionally to its policy orientated contribution, this thesis aims making a methodological contribution by applying a new optimization technique for solving problems where the control variables depend on two or more arguments --- the so-called two-stage solution approach ---, and by applying a numerical method --- the Escalator Boxcar Train Method --- for solving distributed optimal control problems, i.e., problems where the state variables, in addition to the control variables, depend on two or more arguments. Chapter 2 presents a theoretical framework to determine optimal resource allocation over time for the production of a good by heterogeneous producers, who generate a stock externalit and derives government policies to modify the behavior of competitive producers in order to achieve optimality. Chapter 3 illustrates the method in a more specific context, and integrates the aspects of quality and time, presenting a theoretical model that allows to determine the socially optimal outcome over time and space for the problem of waterlogging in irrigated agricultural production. Chapter 4 of this thesis concentrates on forestry resources and analyses the optimal selective-logging regime of a size-distributed forest.

Multimedia Interactive Book (miBook) reflects the development of a new concept of virtual interpretation of traditional text books and audio-visual content. By encompassing new technological approaches, using augmented reality technology, allows the final user to experience a variety of sensorial stimuli while enjoying and interacting with the content; therefore enhancing the learning process. miBook stands for a global educational intention to enable people not only to access but also to appropriate intellectually valuable contents coming from different linguistic and cultural contexts.
