The influence of rock fabric in the durability of two sandstones used in the Andalusian Architectural Heritage (Montoro and Ronda, Spain)

Natural stone has been a popular and reliable building material throughout history appearing in many historic monuments and in more recent buildings. Research into the intrinsic properties of specific stones is important because it gives us a greater understanding of the factors that limit and act on them. This can help prevent serious problems from occurring in our buildings bringing both esthetic benefits and financial savings. To this end, the main objective of this research has been to study the influence of the fabric and the mineral composition of two types of sandstone on their durability. The first is a red continental sandstone from the Buntsandstein Age called “Molinaza Roja”, which is quarried in Montoro (Cordoba). The second is quarried in Ronda (Malaga) and is sold under the trade name of “Arenisca Ronda”. It is a light pink-whitish calcarenite deposited during the Late Tortonian to Late Messinian. We characterized their petrological and petrophysical properties by studying their rock fabrics, porous systems and mechanical properties. In order to obtain a complete vision of the behavior of their rock fabrics, we also carried out two decay tests, the salt crystallization and the freeze–thaw tests. We then measured the effects on the textures of the altered samples during and after the decay tests and we evaluated the changes in the porous system. By comparing the results between intact and altered samples, we found that Arenisca Ronda is less durable because it has a high quantity of expandable clays (smectites) and a high percentage of pores in the 0.1–1 μm range, in which the pressure produced by salt crystallization is strongest. In Molinaza Roja the decay agents caused significant sanding due to loss of cohesion between the clasts, especially during the salt crystallization test. In both stones, the anisotropies (oriented textures) have an important role in their hydric and dynamic behavior and also affect their mechanical properties (especially in the compression resistance). No changes in color were detected.

Tourism potential analysis of the castles of Vinalopó, Spain: an opportunity for social and tourist development of cultural heritage

Within the overall framework of the renewal process of coastal tourist destinations, cultural heritage has frequently been used as a key argument for the introduction and development of strategies for the diversification and differentiation of the traditional tourist product based on sun and sand. This is the situation of the province of Alicante, identified with the Costa Blanca geotourism brand, where there are important economic issues that could contribute to the renewal of this coastal tourist destination. One of the most significant heritage values of this space consists of a series of medieval fortresses located along the axis of the Vinalopó River, which has acted since prehistoric times as a natural route from within the provincial mainland to the coast. It is precisely the argument of this historical, territorial and landscape content that has been used repeatedly in recent years to develop initiatives aimed at the creation of a tourist product, currently inexistent, based on the route of the castles of Vinalopó. This communication aims to analyse the degree of tourism potential of the fortresses located in the towns of Biar, Banyeres de Mariola, Sax, Villena, Novelda, Elda, Petrer and Elche, which constitute the core of municipalities where these medieval fortresses are located, finally pointing out some proposals for the creation of a heritage tourism product.

Causal Maps and Indirect Influences Analysis in the Diagnosis of Second-Home Tourism Impacts

This paper proposes a method for diagnosing the impacts of second-home tourism and illustrates it for a Mediterranean Spanish destination. This method proposes the application of network analysis software to the analysis of causal maps in order to create a causal network model based on stakeholder-identified impacts. The main innovation is the analysis of indirect relations in causal maps for the identification of the most influential nodes in the model. The results show that the most influential nodes are of a political nature, which contradicts previous diagnoses identifying technical planning as the ultimate cause of problems.

Exploring the relationship between educational mismatch, earnings and job satisfaction in the tourism industry

This article analyses the interrelationship between educational mismatch, wages and job satisfaction in the Spanish tourism sector in the first years of the global economic crisis. It is shown that there is a much higher incidence of over-education among workers in the Spanish tourism sector than in the rest of the economy despite this sector recording lower educational levels. This study estimates two models to analyse the influence of the educational mismatch on wages and job satisfaction for workers in the tourism industry and for the Spanish economy as a whole. The first model shows that in the tourism sector, the wage penalty associated with over-education is approximately 10%. The second reveals that in the tourism sector the levels of satisfaction of over-educated workers are considerably lower than those corresponding to workers well assigned. With respect to the differences between tourism and the overall economy in both aspects, the wage penalty is substantially lower in the case of tourism industries and the effect of over-education on job satisfaction is very similar to that of the economy as a whole in a context where both wages and the private returns to education are considerably lower in the tourism sector.

Renovación de destinos litorales maduros a partir del patrimonio cultural: Plan Costa Blanca Cultura

El destino turístico Costa Blanca se caracteriza por la existencia de una amplia oferta turística y por su situación privilegiada respecto a los mercados potenciales de demanda. En la actualidad, ambas características no son suficientes para garantizar la competitividad de este espacio; en un contexto turístico enormemente dinámico en el que la diversidad de elementos de atracción y la imagen del destino puede incidir en la decisión de viaje de los turistas. Por ello, ante la necesidad de acometer procesos de renovación del destino Costa Blanca que permitan garantizar la competitividad de la actividad en términos territoriales y económicos, se apuesta por el patrimonio cultural como uno de los argumentos que mayores posibilidades puede ofrecer desde el ámbito de la planificación del destino turístico para diseñar y ejecutar actuaciones encaminadas a la renovación del mismo. Así, la presente comunicación se basa en los principales resultados obtenidos en el Plan Costa Blanca Cultura, con el objetivo de analizar el grado de uso turístico del patrimonio cultural de la provincia de Alicante, para a partir de un diagnóstico previo, proponer estrategias y actuaciones encaminadas al diseño y gestión posterior de productos temáticos de naturaleza cultural. La metodología de trabajo se ha basado entre otras acciones, en la participación de los agentes turísticos y sociales, aspecto que ha llevado a la selección de las líneas de trabajo prioritarias basadas en temas que superarían la dicotomía entre litoral e interior otorgando al patrimonio un papel integrador del territorio, y a la propuesta de un modelo de gestión innovador en el destino Costa Blanca.

Ciudad de Vacaciones 1933. El concurso internacional para Playa de San Juan (Alicante)

En 1933, por iniciativa municipal y con el apoyo del Gobierno, con la intención de captar un turismo extranjero y nacional de élite generando una nueva ‘industria’, se convoca el concurso de anteproyectos para la construcción de una ciudad satélite (a modo de ciudad jardín) para destinarla a ciudad de vacaciones en la Playa de San Juan (cvPSJ), Alicante, al que se presentan tres propuestas. Aquí se estudia el anteproyecto ganador (de P. Muguruza), que resulta pionero por las técnicas urbanísticas empleadas (información y zonificación), por la aplicación de la fotografía para la inserción de arquitecturas y equipamientos y por la sensibilidad desplegada en la protección del patrimonio cultural (medioambiental e histórico). Los referentes para este macro complejo turístico (de casi 10 km2), coetáneo a la Ciutat del Repós i Vacances (CRV) de Castelldefels, no proceden tanto de Europa como de EUA. Se realiza un análisis pormenorizado de la ordenación urbanística en atención a cómo el territorio existente la condiciona y se entrelaza con estrategias de promoción turística, donde se combinan la tríada: hotel, deporte y naturaleza (alojamiento, ocio y salud). Pero toda la ciudad está enfocada a un turismo burgués, para el que se prevé una arquitectura comercial que pronto envejecería en su repertorio. Veinticinco años después, en 1958, cuando las condiciones económicas y sociales fueron favorables al desarrollo de la zona, el mundo sería ya otro y el proyecto quedó obsoleto.

The episcopal complex of Eio-El Tolmo de Minateda (Hellín, Albacete, Spain). Architecture and spatial organization. 7th to 8th centuries AD

The episcopal complex of Eio, located in El Tolmo de Minateda, was built between the end of the 6th century and the beginning of the 7th century, possibly as a political decision taken by the ecclesiastical authority in the capital of the Visigothic kingdom (Toletum). With the comprehensive study of the whole complex presented below (construction cycles, furniture, decoration and location of spaces), we can interpret the function of each space in the basilica and the domus episcopi, the liturgical and general movement routes, the existence of some hierarchical environments, and specify the chronological development of the buildings. After the Arab-Berber conquest of Hispania in the early 8th century, the whole complex will experience a series of transformations that will convert the religious and monumental public area into a private, residential and industrial Islamic quarter.

Methodology based on registration techniques for representing subjects and their deformations acquired from general purpose 3D sensors

In this thesis a methodology for representing 3D subjects and their deformations in adverse situations is studied. The study is focused in providing methods based on registration techniques to improve the data in situations where the sensor is working in the limit of its sensitivity. In order to do this, it is proposed two methods to overcome the problems which can difficult the process in these conditions. First a rigid registration based on model registration is presented, where the model of 3D planar markers is used. This model is estimated using a proposed method which improves its quality by taking into account prior knowledge of the marker. To study the deformations, it is proposed a framework to combine multiple spaces in a non-rigid registration technique. This proposal improves the quality of the alignment with a more robust matching process that makes use of all available input data. Moreover, this framework allows the registration of multiple spaces simultaneously providing a more general technique. Concretely, it is instantiated using colour and location in the matching process for 3D location registration.
