The loyalty of young residents in an island destination: An integrated model.

This paper investigates the factors that influence the loyalty of young residents as tourists in their home destination in the context of domestic tourism. The interest in studying the loyalty of this particular population segment stems from their consumption potential, their influence, and for the triple role they can play as tourists in the destination, as residents in the destination and as collaborators with local tourism companies. The setting for this study is one of growing domestic tourism in a destination made up of islands, the Canary Islands (Spain). The importance of this kind of research for island destinations arises from the negative impacts of tourism that island destinations suffer more than others, often with negative repercussions on loyalty. This paper studies the role of tourism companies, the product, the place and the young residents themselves in the formation of loyalty. A sample of 678 young residents from the Canary Islands responded to an ad hoc questionnaire of 22 items. The descriptive analysis highlights that young residents value to varying degrees all the variables included in the model (tourism companies, place, product and tourist variables). The discriminant analysis shows that there are no significant differences in the perceptions of young residents according to gender, island of residence or the number of trips made within the destination, which confirms the generational nature of the study and the possibility of extrapolating the results. Using the causal model proposed, the formation of loyalty among young residents is explained. In this model, the variables related to the company and the product hardly influence loyalty formation among young residents when these variables are integrated into the same model with place variables (identity, attachment and familiarity). These variables initiate the chain of cause and effect that culminates in the formation of satisfaction and loyalty among tourists, relegating company and product variables to the background

Thru reflect line calibration for empty substrate integrated waveguide with microstrip transitions

In past years, a great number of substrate integrated circuits have been developed. Among these new transmission lines, the substrate integrated waveguide (SIW) has received special attention. Although the quality factor and losses of these new integrated lines are better than the planar circuits, these characteristics are worst than in the case of waveguides, mainly due to the presence of dielectric substrate. To improve the performance of the integrated circuits, a new methodology for manufacturing the empty waveguides, without dielectric substrate, but at the same time completely integrated in a planar substrate, has been recently proposed, resulting in the novel empty SIW (ESIW). A low-cost and easy to manufacture thru reflect line calibration kit for de-embedding the effect of connectors and transitions when measuring ESIW devices is presented. Results prove the high quality of this calibration kit.Fernández Berlanga, M.; Ballesteros Garrido, J.; Martínez Cano, L.; Esteban González, H.; Belenguer Martínez, A. (2015).

Short-term effects of impurities in the CO2 stream injected into fractured carbonates.

After the Paris Agreement in which 195 countries are involved, the Carbon Capture and Storage (CCS) is now an accepted technology in the United Nations Framework Convention on Climate Change (UNFCCC). In Spain, Fundación Ciudad de la Energía (CIUDEN) has successfully completed the full CCS chain, being CO2 captured in the Technology Development Centre in Cubillos del Sil (León, Spain) whereas that it is geologically stored in a deep saline aquifer, formed by fractured carbonates with poor matrix porosity, located in the Technology Development Plant (TDP) at Hontomín (Burgos, Spain). The results of the field tests, in which up to 150 tons of CO2 and synthetic air (5 %v of N2 and O2) were co-injected on site, are analyzed in this paper comparing the operational parameters gained during the injection of impure CO2 (pressures, temperatures and flow ranges) with its corresponding baseline previously determined (i.e. 1,500 tons of pure CO2 were injected during the reservoir hydraulic characterization). Besides that, the geochemical reactivity analysis of impure CO2 injected in this saline aquifer and its correlation with the results from laboratory tests were assessed. As main conclusions from laboratory scale results, a porosity diminution was measured after the injection of CO2 with 5 %v of SO2; apart from that, without SO2, the effluent pH was in the range of 7-8 whereas in case of CO2 and SO2, a pH of 1-2 was obtained. Otherwise and focused on field scale tests, a density decrease was detected comparing the base case (pure CO2) with the CO2 injection containing 5.1 %v of synthetic air. On the other hand, Ca2+, SO42-, Mg2+ and K+ migration effects in the rock were also detected and analyzed

Manejo perioperatorio de fármacos anticoagulantes y antiagregantes en el paciente con fractura de cadera

La fractura de cadera eleva de manera significativa en los estudios publicados la morbilidad y la mortalidad en los pacientes ancianos que la padecen. La participación en el proceso de fármacos que alteran la hemostasia se ha convertido en uno de los aspectos más importantes y controvertidos del manejo perioperatorio del paciente con fractura de cadera. La anticoagulación o antiagregación plaquetaria de estos pacientes tiene unas implicaciones tanto en la práctica anestésica como quirúrgica que hacen necesaria la búsqueda de un equilibrio entre el riesgo hemorrágico y trombótico de los mismos. Con la elaboración del presente protocolo, en línea con las últimas evidencias científicas publicadas, se sientan las bases para avanzar en el tratamiento de este grupo de pacientes. Una atención multidisciplinar especializada, una fijación precoz de la fractura antes de las 48 horas, y un efectivo programa de rehabilitación pueden disminuir las complicaciones del proceso.Hip fracture rises significantly in published studies morbidity and mortality in elderly patients. Participation in the process of hemostasis-altering drugs has become one of the most important and controversial perioperative management of patients with hip fracture aspects. Anticoagulation or antiplatelet of these patients have some implications as a surgical anesthetic practice that make it necessary to seek a balance between bleeding and thrombotic risk thereof. With the development of this protocol, in line with the latest scientific evidence published, the stage is set to advance the treatment of this patient group. A specialized multidisciplinary care, early fracture fixation within 48 hours and an effective rehabilitation program can reduce complications of that process

Towards an integrated approach for monitoring the effects of chemical contaminants in the Spanish coastal Mediterranean waters

Oral communicationIn the past twelve years, chemical monitoring surveys in Spanish Mediterranean coastal waters have developed from the use of native mussels to an integrated sampling of native and caged mussels, fish (red mullet) and sediment. In addition, the application of biological effect measurements (using biomarkers and bioassays) in the same matrices is being gradually arising. So far, biological measurements have comprised a suite of biomarkers in fish (EROD, Ala-D and AChE activities, Metallothionein content, DNA integrity and micronuclei abnormalities) and in mussels (Stress on Stress, lysosomal membrane stability, Metallothionein content, Micronuclei frequency, AChE and antioxidant enzymes) as well as the sea urchin embryotoxicity test with Paracentrotus lividus in sediment elutriates. Most of the driving forces behind these changes came from recommendations and Standard Operation Practices provided by expert organizations as MED POL, ICES, and OSPAR, and these changes have considerably increased the costs of monitoring. However, higher costs of intensive monitoring activities will allow contributing to a more realistic assessment of the quality and health status of the marine ecosystem. For this purpose quality assurance and the development of assessment criteria for the selected methods is a prerequisite. These requirements are necessary to meet national and international obligations (EU-MSFD, EU-WFD). Here, we present and discuss the integrated chemical-biological effect approach that is currently being proposed for implementation in the Spanish Mediterranean monitoring programme 2010-2012. The selected biological measurements, the assessment criteria obtained so far and quality assurance processes are discussed in terms of feasibility.The Spanish Mediterranean Biomonitoring Programs of chemical contamination (BMCW and BMIS programs) are conducted by the Instituto Español de Oceanografía (IEO) under the responsibility of the Ministry of Environment (MEDPOLIEO Project in 2006 and 2-ESMARME Project in 2010-2012)

Biomonitoring strategy to assess the effects of chemical pollution along the Iberian Mediterranean Coast: Present state and future development

oral presentationSince 2001, the Oceanographic Centre of Murcia (Spanish Institute of Oceanography, IEO) started to include selected biomarkers within the chemical pollution monitoring activities conducted along the Iberian Mediterranean coast. The main objectives of this biomonitoring programme are: (1) the determination of spatial distribution and temporal trends of chemical pollution in coastal and reference areas; (2) to seek evidence of detrimental biological effects and assess them over time. Sediment samples, feral fish (Mullus barbatus) and wild mussels (Mytilus galloprovincialis) are analysed yearly for selected pollutants (trace metals, organochlorinated compounds and polycyclic aromatic hydrocarbons) and selected biomarkers are measured in fish and/or mussels (EROD activity, metallothionein content, micronuclei frequency, genotoxic damages, acetylcholinesterase, stress on stress and lysosomal membrane stability). An integrated chemical-biological effect assessment approach is being conducted at four selected areas since 2006. Due to its geographical location, Spain contributes to both the CEMP and MEDPOL programmes and our future strategy will be focused to achieve the harmonization of criteria among different programmes and to meet the monitoring requirements in a cost-effective and cost-efficient way. The general strategy and methods of this biomonitoring programme together with some preliminary results and future development (use of caged mussels) are described and discussed.This Biomonitoring Programme was initially funded by the Spanish Institute of Oceanography, IEO (projects BIOMEJIMED I, BIOMEJIMED II and BIOMEJIMED III). Since November 2005 it is funded by Ministry of Environment (MEDPOLIEO project)

Evaluation of the contribution of D9S1120 to anthropological studies in Native American populations

The D9S1120 locus exhibits a population-specific allele of 9 repeats (9RA) in all Native American and two Siberian populations currently studied, but it is absent in other worldwide populations. Although this feature has been used in anthropological genetic studies, its impact on the evaluation of the structure and genetic relations among Native American populations has been scarcely assessed. Consequently, the aim of this study was to evaluate the anthropological impact of D9S1120 when it was added to STR population datasets in Mexican Native American groups. We analyzed D9S1120 by PCR and capillary electrophoresis (CE) in 1117 unrelated individuals from 13 native groups from the north and west of Mexico. Additional worldwide populations previously studied with D9S1120 and/or 15 autosomal STRs (Identifier kit) were included for interpopulation analyses. We report statistical results of forensic importance for D9S1120. On average, the modal alleles were the Native American-specific allele 9RA (0.3254) and 16 (0.3362). Genetic distances between Native American and worldwide populations were estimated. When D9S1120 was included in the 15 STR population dataset, we observed improvements for admixture estimation in Mestizo populations and for representing congruent genetic relationships in dendrograms. Analysis of molecular variance (AMOVA) based on D9S1120 confirms that most of the genetic variability in the Mexican population is attributable to their Native American backgrounds, and allows the detection of significant intercontinental differentiation attributed to the exclusive presence of 9RA in America. Our findings demonstrate the contribution of D9S1120 to a better understanding of the genetic relationships and structure among Mexican Native groups.CONACYT (Consejo Nacional de Ciencia y Tecnología) (México)Depto. de Biodiversidad, Ecología y EvoluciónFac. de Ciencias BiológicasTRUEinpres

Using warping information for batch process monitoring and fault classification

This paper discusses how to use the warping information obtained after batch synchronization for process monitoring and fault classification. The warping information can be used for i) building unsupervised control charts or ii) fault classification when a rich faulty batches database is available. Data from realistic simulations of a fermentation process of the Saccharomyces cerevisiae cultivation are used to illustrate the proposal.This research work was supported by the Spanish government (Ministry of Science and Innovation, MICINN) under project DPI2011-28112-C04-02.
