What Erasmus students do expect from their abroad experience? A multidimensional scale tested for the case of Spain

Purpose - Since universities adopted a 'Student as Customer' approach, student consumer behavior is a field of study which has become crucial. In the European higher education area, more understanding is needed on International students, and more precisely on Erasmus students. The purpose of this paper is to validate a multidimensional scale to assess Erasmus students' value expectations (i.e. expected value) on the basis of costs and benefits in their choices as consumers of an academic experience abroad. Design/methodology/approach - A survey conducted on a sample of 192 students from 50 universities show the role of functional, social and emotional values along with costs of time and effort in the perceived value of an Erasmus experience. Findings - After validating the five scales, the results show that social and emotional are the aspects were students' expected value dimensions are the highest, as the Erasmus experience is expected to enrich their studies and enable them to boost their self-confidence, while functionally helping them to find a job in the future. Concerning the sacrifices, the Erasmus experience has a high cost with regard to effort, time and energy, but students are willing to go through it: an Erasmus stay is seen as a good investment, whose benefits will be reaped in the long run. Originality/value - The contribution of this paper comes from the scope and the target: a multidimensional trade-off approach to the expected value of the Erasmus experience. Other works have already depicted the educational experience through the value concept, but none, to the best of the authors' knowledge, has measured expected value on the pre-purchase phase for Erasmus students

Soundscape Evaluation of a Heritage Event in an Open Environment: The Water Tribunal of the Plain of Valencia (Spain)

[EN] The acoustic evaluation of indoor environments is common in the application of virtual acoustics. In addition, in the study of cultural heritage buildings, it is a useful tool, but it is not so common when describing the acoustic environment in intangible cultural heritage events and even in outdoor environments. In this paper, the acoustic environment of the Water Tribunal of the Plain of Valencia (Spain) is studied. It is analyzed from a soundscape perspective, characterizing the sound source and evaluating it within relation to the environment and evaluating its subjective response. With the research carried out, it has been obtained, on the one hand, a complete study of the acoustics of the environment of the Water Tribunal and, on the other, an enhancement of the Valencian tangible and intangible heritage.This research was partially funded by Spanish Ministry of Science, Innovation and Universities, grant number BIA2016-76957-C3-3-R and by the Universitat de Valencia with the grant UV-INV-AE-1550319.Díaz-Rubio, E.; Segura-Garcia, J.; Fayos-Jordan, R.; Cerdá, S.; Cibrián, RM.; Giménez Pérez, A.

Anharmonic dynamics in crystalline, glassy, and supercooled-liquid glycerol: A case study on the onset of relaxational behavior

10 págs.; 8 figs.The temperature dependence of the spectral distributions of the glass, crystalline, and supercooled-liquid phases of glycerol is investigated by means of neutron inelastic scattering. The importance of anharmonic effects is quantified by the temperature dependence of reduced spectral frequency moments. The onset of relaxational (i.e., stochastic, zero-frequency) motions in the supercooled liquid state is monitored by neutron quasielastic scattering. A substantial deviation of the observed linewidths from the hydrodynaimc prescription is observed and is interpreted at a microscopic level, by comparison with the crystalline phase. ©1998 American Physical SocietyWork supported in part by DGICYT ~Spain!

Metodología para la mejora acústica de recintos de culto. Aplicación en la Catedral de Valencia

Los recintos de culto son espacios patrimoniales de gran valor cultural, artístico y arquitectónico. Asimismo, en ellos tienen lugar eventos, integrantes de su patrimonio cultural inmaterial, donde la transmisión del sonido es un factor preferente. Por todo ello, resulta relevante garantizar un adecuado acondicionamiento acústico de los recintos de culto para sus dos usos fundamentales, la música religiosa y la palabra. Para ello, se ha establecido una metodología compuesta por las fases de medición acústica, estudio del comportamiento acústico del recinto, levantamiento y calibración del modelo acústico y simulaciones acústicas. Al tratarse de edificios protegidos, las propuestas de intervención deben basarse en el respeto a los valores patrimoniales de los templos. Con todo ello, en este estudio se ha realizado una propuesta de mejora del acondicionamiento acústico de la Catedral de Valencia

Likewise, events take place in them, members of their intangible cultural heritage, where the transmission of sound is a preferential factor. Therefore, it is important to guarantee an adequate acoustic conditioning of the places of worship for its two fundamental uses, religious music and speech. For this, a methodology has been established consisting of the phases of acoustic measurement, study of the acoustic behavior of the enclosure, lifting and calibration of the acoustic model and acoustic simulations. As they are protected buildings, intervention proposals must be based on respect for the heritage values of temples. With all this, in this study a proposal has been made to improve the acoustic conditioning of the Cathedral of Valencia.Este estudio ha sido subvencionado por el Ministerio de Ciencia e Innovación a través de los proyectos de investigación BIA2012-36896 y BIA2016-76957-C3-3-RDíaz-Rubio, E.; Montell Serrano, RE.; Cerdá Jordá, S.; Segura Garcia, J.; Cibrián Ortíz De Anda, R.; Barba Sevillano, A.; Lacatis, RG....

Critical reflections on asymptotically safe gravity

Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field theories, in particular for quantum gravity. Significant progress on this program has led to a first characterization of the Reuter fixed point. Further advancement in our understanding of the nature of quantumspacetime requires addressing a number of open questions and challenges. Here, we aim at providing a critical reflection on the state of the art in the asymptotic safety program, specifying and elaborating on open questions of both technical and conceptual nature. We also point out systematic pathways, in various stages of practical implementation, toward answering them. Finally, we also take the opportunity to clarify some common misunderstandings regarding the program

Environmentally sensitive paramagnetic and diamagnetic contrast agents for nuclear magnetic resonance imaging and spectroscopy

Even though alterations in the microenvironmental properties of tissues underlie the development of the most prevalent and morbid pathologies, they are not directly observable in vivo by Magnetic Resonance Imaging (MRI) or Spectroscopy (MRS) methods. This circumstance has lead to the development of a wide variety of exogenous paramagnetic and diamagnetic MRI and MRS probes able to inform non invasively on microenvironmental variables such as pH, pO(2), ion concentration o even temperature. This review covers the fundamentals of environmental contrast and the current arsenal of endogenous and exogenous MRI and MRS contrast enhancing agents available to visualize it. We begin describing the physicochemical background necessary to understand paramagnetic and diamagnetic contrast enhancement with a special reference to novel magnetization transfer and C-13 hiperpolarization strategies. We describe then the main macrocyclic structures used to support the environmentally sensitive paramagnetic sensors, including CEST and PARACEST pH sensitive probes, temperature probes and enzyme activity or gene expression activatable probes. Finally we address the most commonly used diamagnetic contrast agents including imidazolic derivatives to reveal extracellular pH and tissue pO(2) values by MRS. The potential applications of these agents in mutimodal and molecular imaging approaches are discussed.This work was supported in part by grants: CTQ2006-06505/BQU, CTQ2009-14146-C01/C02, to P.B. and P.L.L., S-BIO/0179/2006 and SAF2008/01381 to SC and EU MEDITRANS Integrated Project NMP4-CT- 2006-02668 to S.C., P.L.L. and P.B.
