Hotel abierto. El sector hotelero ante las nuevas demandas de accesibilidad para todos (análisis, propuestas y la experiencia de 22 hoteles)

Este documento pretende ser un instrumento para favorecer la mejora de accesibilidad, pero no tiene una caracterización fácil dada la diversidad de aspectos abordados. En primer lugar parte del estudio de los condicionantes normativos y económicos que inciden sobre el mercado hotelero y los fallos o consecuencias negativas que el diseño de las normas puede tener para la penetración de la accesibilidad en los hoteles, lo que da pie a consideraciones sobre la intervención pública, la aplicabilidad de los instrumentos normativos y el control de su cumplimiento. Como documento de investigación, plantea una metodología de análisis e interpretación del proceso de incorporación de accesibilidad en los hoteles, buscando que este no se focalice exclusivamente en la reforma de espacios, sino en la consideración de los procesos y acciones que desarrolla el viajero, como forma de favorecer la continuidad y la lógica finalista de las intervenciones. Un tercer bloque viene constituido por la presentación de un amplio trabajo de campo con directores de 22 hoteles de los que 17 respondieron a un cuestionario y 10 fueron entrevistados de manera informal, puesto que sus planteamientos, conocimiento y problemática no suele analizarse suficientemente en los trabajos de accesibilidad hotelera. Por último, y a partir de las fotografías que se han podido tomar en los hoteles visitados, se plantean algunas soluciones y comentarios sencillos y visuales a problemas recogidos en la realidad, con el fin de ser didáctico y ofrecer pautas concretas de solución para cada tipo de problema detectado.

Organisational status and efficiency: the case of the spanish SOE "Paradores"

The purpose of this paper is to provide new evidence on the issue of the effect on public enterprises economic performance of the introduction of some given changes in organisational status and management practices, while keeping the enterprises under public control. Our approach is case study type and relies on comparative efficiency literature. We identify relevant changes on the organisational status of a State owned large hotel group along a period of twenty years, next we measure its annual efficiency indicators, and then evaluate to which extent the observed changes in economic performance can be attributable to the corresponding management reforms carried out. As a result we find that the formally more relevant change in organisational status (the enterprise passing to be a Limited Company), which implied a substantial increase in the enterprise autonomy, did not produce a significant improvement in its economic performance; a finding contrary to what we expected according to agency theory. However, a second relevant organisational change –five years later- when both the principal (government) and the agent (firm’s CEO) changed is consistently related to a significant improvement in economic performance. As a research implication we abide for use more precise agency theory statements; and as a practical implication we argue here that potentialities of improvement brought about by a formal-legal change in the status of the enterprise may require also –in order to actually improve firm’s efficiency- some changes in the firm’s key personal positions: supervisor (principal) and CEO (agent), in the sense that a change to a greater-autonomy for the enterprise it seems should come together a parallel new ‘management culture’. Practical implications Management good practises to apply to other public enterprise’s restructuring in order to improve their efficiency. It’s the first study on organizational changes and efficiency for an important Spanish public enterprise.

Nivells de radó en exterior i recintes tancats a la marjal càrstica de Peníscola

S’ha portat a terme un mostreig de diferents punts de la Marjal de Peníscola i 7 instal·lacions properes amb la finalitat de determinar les concentracions de 222Rn en aire exterior i interior. Les anàlisis en els punts exteriors obtenen unes concentracions de 222Rn elevades, superiors a 50 Bq·m-3 en alguns punts. El fet que el sòl de la marjal tingui altes concentracions de 226Ra i elevades concentracions de 226Ra i 222Rn en l’aigua salobre poden justificar aquests valors. L’alta activitat de l’aigua, les característiques de l’edifici i mala gestió del sistema de clavegueram de Peníscola són els responsables de les elevades concentracions de 222Rn en l’aire interior de la depuradora, amb concentracions màximes de més de 70000 Bq·m-3. Un sistema de ventilació adequat com un extractor de PVC evitaria l’acumulació del 222Rn a l’interior de la instal·lació.

Ecoetiques de serveis als establiments hotelers del Parc Natural de l'Alt Pirineu

En el present projecte s’analitza el turisme i la seva relació amb la figura del Parc Natural de l’Alt Pirineu (a partir d’ara PNAP). A la zona d’estudi el turisme és una de les principals activitats econòmiques, donat el notable valor ecologico-cultural de l’indret. L’activitat turística al PNAP és molt diversa, és per aquest motiu que s’observen diverses repercussions en l’entorn segons la tipologia de turisme que es doni. Donada aquesta realitat, l’estudi que es presenta està centrat en el sector hoteler de l’àmbit d’influència del PNAP. D’aquesta forma, s’analitza i diagnostica l’estat de qualitat ambiental dels hotels i pensions que componen el sector. Les eines emprades en aquest estudi han estat dues. Primerament, s’avalua la implantació del Distintiu de Garantia de Qualitat Ambiental (a partir d’ara DGQA). El DGQA és una ecoetiqueta de serveis, de recent creació, que atorga la Generalitat de Catalunya a partir de la revisió de l’establiment per mitjà d’un tècnic autoritzat. En segon terme, s’ha creat i emprat un producte anomenat Enquesta Bàsica d’Auto-xequeig de Qualitat Ambiental (a partir d’ara EBAQA). L’EBAQA té una doble finalitat. Per una banda respon a la necessitat d’autodiagnosi que tenen els propietaris, al ser aquests qui realitzen l’enquesta. Per altra banda, permet determinar quin és l’estat de qualitat ambiental del sector hoteler a la zona d’estudi a partir de l’avaluació de 35 dels 67 establiments existents a l’àmbit d’influència del PNAP, el qual representa una mostra del 61%.

Study of the influence of grain size and precipitates on the electromagnetic losses in different grades of non-oriented fully processed electrical steel

The study was performed in the installations of OCAS, a Steel Research Centre of ArcelorMittal. Taking M32 steel (3.25%Si+0.9%Al) as the basis chemical composition and three different thicknesses (0.35, 0.5 and 0.65mm), different annealing conditions (temperature and time) have been applied in the laboratory simulator at St. Chély, France. The aim was to link annealing parameters, grain size and energy loss. It was determined the optimum annealing parameters to reach the lowest power losses for three different grades of non-oriented fully processed electrical steel. In addition, M250-50 samples having different magnetic behaviour (high and low losses) but the same grain size and texture, have been analyzed in terms of TEM observations of their precipitates, in the University of Marseille. The results reveal that a high amount of medium and big precipitates (&10 nm) worsen the magnetic properties of the material. The small precipitates (&10nm) do not have a strong influence on the magnetic properties. The presence of precipitates can have a great influence on the power losses and further work is clearly necessary.

Towards an emotion-driven interactive music system: ridging the gaps between affect, physiology and sound generation

Report for the scientific sojourn at the Stanford University from January until June 2007. Music is well known for affecting human emotional states, yet the relationship between specific musical parameters and emotional responses is still not clear. With the advent of new human-computer interaction (HCI) technologies, it is now possible to derive emotion-related information from physiological data and use it as an input to interactive music systems. Providing such implicit musical HCI will be highly relevant for a number of applications including music therapy, diagnosis, nteractive gaming, and physiologically-based musical instruments. A key question in such physiology-based compositions is how sound synthesis parameters can be mapped to emotional states of valence and arousal. We used both verbal and heart rate responses to evaluate the affective power of five musical parameters. Our results show that a significant correlation exists between heart rate and the subjective evaluation of well-defined musical parameters. Brightness and loudness showed to be arousing parameters on subjective scale while harmonicity and even partial attenuation factor resulted in heart rate changes typically associated to valence. This demonstrates that a rational approach to designing emotion-driven music systems for our public installations and music therapy applications is possible.

Forecasting the European Carbon Market

In an effort to meet its obligations under the Kyoto Protocol, in 2005 the European Union introduced a cap-and-trade scheme where mandated installations are allocated permits to emit CO2. Financial markets have developed that allow companies to trade these carbon permits. For the EU to achieve reductions in CO2 emissions at a minimum cost, it is necessary that companies make appropriate investments and policymakers design optimal policies. In an effort to clarify the workings of the carbon market, several recent papers have attempted to statistically model it. However, the European carbon market (EU ETS) has many institutional features that potentially impact on daily carbon prices (and associated nancial futures). As a consequence, the carbon market has properties that are quite different from conventional financial assets traded in mature markets. In this paper, we use dynamic model averaging (DMA) in order to forecast in this newly-developing market. DMA is a recently-developed statistical method which has three advantages over conventional approaches. First, it allows the coefficients on the predictors in a forecasting model to change over time. Second, it allows for the entire fore- casting model to change over time. Third, it surmounts statistical problems which arise from the large number of potential predictors that can explain carbon prices. Our empirical results indicate that there are both important policy and statistical bene ts with our approach. Statistically, we present strong evidence that there is substantial turbulence and change in the EU ETS market, and that DMA can model these features and forecast accurately compared to conventional approaches. From a policy perspective, we discuss the relative and changing role of different price drivers in the EU ETS. Finally, we document the forecast performance of DMA and discuss how this relates to the efficiency and maturity of this market.

The regional employment impacts of renewable energy expenditures: The case for modelling

One aspect of the case for policy support for renewable energy developments is the wider economic benefits that are expected to be generated. Within Scotland, as with other regions of the UK, there is a focus on encouraging domestically‐based renewable technologies. In this paper, we use a regional computable general equilibrium framework to model the impact on the Scottish economy of expenditures relating to marine energy installations. The results illustrate the potential for (considerable) ‘legacy’ effects after expenditures cease. In identifying the specific sectoral expenditures with the largest impact on (lifetime) regional employment, this approach offers important policy guidance.
