Evaluating the resources in a tourism destination is one of the previous tasks in the development of its comprehensive planning. There are many criteria to use in order to evaluate tourism resources; but, independently on the number of attributes considered the fact is that not every criterion is equally important in the process of evaluation and ranking of the tourism potential of a destinations resources. In contrast to other well-known methodologies, the aim of this paper is to propose a methodology to weight qualitative and hierarchical evaluation attributes by estimating a discrimination parameter. In this research, an item response theory (IRT) model is used, the graded response model, to estimate each attributes discrimination coefficient. This parameter will be the basis to propose a weighting system for the entire set of attributes. Graded response model (GRM) will also allow establishing a hierarchy of resources by constructing a continuous latent scale, where it will be possible to position every analysed resource in the tourism destination. The applicability and robustness of the IRT methodology will be tested using data from rural tourism resources in the Spanish province of Cáceres.Evaluating the resources in a tourism destination is one of the previous tasks in the development of its comprehensive planning.

Este articulo propone la caracterizacion del territorio turistico de Extremadura a partir del analisis de grupos (Grouping Analysis), tecnica vinculada a la geoestadistica. En la configuracion de territorios homogeneos se consideran las variables relativas a los atractivos y la oferta de alojamientos y restauracion y, ademas, se recurre al criterio espacial. Por ello, la tecnica propuesta, trata de ir mas alla de los analisis exclusivamente cuantitativos al incorporar el espacio proximo como factor destacado a la hora de establecer grupos homogeneos. Tras realizar numerosos ensayos, utilizando variables muy diversas y diferentes criterios de restriccion espacial, desde la omision del mismo hasta la consideracion de tres vecinos como criterio de distancia, se pone de manifiesto que los resultados que ofrece la utilizacion de este ultimo criterio son sensiblemente mejores que los obtenidos con la omision del criterio espacial. Como consecuencia de su desarrollo se obtienen 14 territorios turisticos bien diferenciados.

The number of second-hand homes held by banks has increased significantly in the last ten years as a result of the economic and mortgage crisis. The considerable increase in the toxic real estate assets package (more than 36% between 2012 and 2015) comes largely from banking defaults by families. The city of Madrid is one of the municipalities most affected by this phenomenon, in which evictions accumulate day after day. This study quantifies and analyses, through the information provided by the real estate departments of the top five banks in the country, this housing pool of second-hand homes in the Spanish capital. Their location within the city allows a knowledge of the degree of affectation by districts. Furthermore, we used the Local Administration’s socio-economic database to determine the social impact of the positioning of private banking. The maps produced by means of Geographic Information Systems have revealed anomalous behaviour of banks in relation to the second-hand housing market in the city of Madrid.

Protected areas have grown very quickly in the last century, achieving significant figures which, however, vary very significantly from one country to another. This interest in protecting natural areas is related, in the current context, with different objectives: scientific, educational, recreational and socioeconomic. As a result, we have a new scenario in which certain traditional uses are being affected. Hunting is undoubtedly one of the best examples of traditional activity that is being affected by this process. With this background, this paper analyses the general situation of protected natural spaces in Extremadura in relation to hunting. This analysis takes into account the fact that a third of the regional territory is protected by some of the existing mechanisms and, moreover, these spaces are distributed in areas where hunting has been a traditional activity that has helped to keep the spaces in a good state of conservation.
