Stability of the factorial structure of metabolic syndrome from childhood to adolescence : a 6-year follow-up study

Background: Metabolic syndrome (MS) is a clustering of cardiometabolic risk factors that is considered a predictor of cardiovascular disease, type 2 diabetes and mortality. There is no consistent evidence on whether the MS construct works in the same way in different populations and at different stages in life. Methods: We used confirmatory factor analysis to examine if a single-factor-model including waist circumference, triglycerides/HDL-c, insulin and mean arterial pressure underlies metabolic syndrome from the childhood to adolescence in a 6-years follow-up study in 174 Swedish and 460 Estonian children aged 9 years at baseline. Indeed, we analyze the tracking of a previously validated MS index over this 6-years period. Results: The estimates of goodness-of-fit for the single-factor-model underlying MS were acceptable both in children and adolescents. The construct stability of a new model including the differences from baseline to the end of the follow-up in the components of the proposed model displayed good fit indexes for the change, supporting the hypothesis of a single factor underlying MS component trends. Conclusions: A single-factor-model underlying MS is stable across the puberty in both Estonian and Swedish young people. The MS index tracks acceptably from childhood to adolescence.

Incubadoras y aceleradores de crecimiento: modelo de apoyo a las start-up tecnológicas

[ES]Las políticas de apoyo al emprendimiento se han demostrado imprescindibles para el desarrollo económico de los países. En este contexto las conocidas incubadoras de empresas juegan un papel importante, pero los innovadores aceleradores de crecimiento que están logrando convertir pequeñas start-up en grandes compañías de base tecnológica se presentan como una apuesta para el futuro. La unión de ambos conceptos constituye un modelo eficaz de apoyo a las start-up tecnológicas. En el trabajo se presentan varios estudios que demuestran que mientras que, en las incubadoras los recursos más valorados son el ahorro de costes y el mentoring, los aceleradores obtienen muy buena calificación en todos sus ámbitos. Aun así la facilidad para obtener financiación y el mentoring también son los aspectos más valorados por los participantes en la aceleración. Además se han utilizado dos casos de éxito con el objeto de proponer un corolario de buenas prácticas que ayude entre otros, a la mejora de la situación de la Comunidad Autónoma del País Vasco (CAPV) en cuanto a emprendimiento se refiere.

Unveiling the factors shaping the distribution of widely distributed alpine vertebrates, using multi-scale ecological niche modelling of the bat Plecotus macrobullaris

Several alpine vertebrates share a distribution pattern that extends across the South-western Palearctic but is limited to the main mountain massifs. Although they are usually regarded as cold-adapted species, the range of many alpine vertebrates also includes relatively warm areas, suggesting that factors beyond climatic conditions may be driving their distribution. In this work we first recognize the species belonging to the mentioned biogeographic group and, based on the environmental niche analysis of Plecotus macrobullaris, we identify and characterize the environmental factors constraining their ranges. Distribution overlap analysis of 504 European vertebrates was done using the Sorensen Similarity Index, and we identified four birds and one mammal that share the distribution with P. macrobullaris. We generated 135 environmental niche models including different variable combinations and regularization values for P. macrobullaris at two different scales and resolutions. After selecting the best models, we observed that topographic variables outperformed climatic predictors, and the abruptness of the landscape showed better predictive ability than elevation. The best explanatory climatic variable was mean summer temperature, which showed that P. macrobullaris is able to cope with mean temperature ranges spanning up to 16 degrees C. The models showed that the distribution of P. macrobullaris is mainly shaped by topographic factors that provide rock-abundant and open-space habitats rather than climatic determinants, and that the species is not a cold-adapted, but rather a cold-tolerant eurithermic organism. P. macrobullaris shares its distribution pattern as well as several ecological features with five other alpine vertebrates, suggesting that the conclusions obtained from this study might be extensible to them. We concluded that rock-dwelling and open-space foraging vertebrates with broad temperature tolerance are the best candidates to show wide alpine distribution in the Western Palearctic.

Marketin Esperientziala: Kasu praktikoa. Pop-up Storeak.

Aditu askoren arabera, milurteko berriaren atarian marketin filosofia berri bat hasi zen loratzen: Marketin Esperientziala. Filosofia berri horrek paradigma aldaketa bat suposatzen du, fokua bezeroek enpresekin bizi dituzten esperientzia gogoangarrietan jartzen duena. Gaur egun, produktu eta zerbitzuak geroz eta antzekoagoak dira, kalitate eta prezioan oinarritutako lehia ez da nahikoa eta bezeroa geroz eta zorrotzagoa da. Horrek guztiak desberdintzeko bide berriak bilatu beharra dakar eta, horregatik, produktu eta zerbitzuez gain esperientziak sortu eta eskaintzea aukera paregabea bilakatu da enpresentzat, hau da, faktore emozionala kontuan hartzea. Gradu Amaierako Lan honek filosofia berri horren nondik norakoak aztertzea bilatzen du eta baita erosketa puntuan nola aplikatzen den ikertzea ere; izan ere, erosketa puntuek bezeroa, produktu/zerbitzua eta langileak atmosfera bakar batean biltzen dituzte. Horretarako, erosketa puntuan parte-hartzen duten esperientzia-eragile nagusiak aztertuko dira: zentzumenak, estetika eta diseinua eta langileen portaera. Ondoren, adibide gisa kasu praktiko eta esanguratsu bat aztertuko da: Pop Up Storeak edo, beste era batera esanda, aldi baterako establezimenduak.

Orígenes indoeuropeos (y no indoeuropeos) de la vocal [y] eslava

[ES] La vocal 'y' de las lenguas eslavas procede esencialmente de i.e. *ū. Pero en el dominio de la flexión tanto nominal como verbal se puede encontrar asimismo una vocal 'y' de origen intraeslavo y derivada de diversas secuencias en final de palabra. Al estudio de estas evoluciones así como al análisis de los distintos estratos de préstamos léxicos que incrementan la presencia de la vocal y en el léxico eslavo se dedica buena parte de este trabajo. En él se rastrean, además, los datos comparativos e internos que permiten detectar otro origen para la vocal eslava 'y' los diptongos i.e. *ou y *au.

Building up a frequency stabilisation based on a wavemeter for a diode laser and characterisation for a digital mirror device for artificial potentials

It has built and characterised a laser and It has learned what each of the components does. It has been able to run the laser in single-mode and stabilised it around a desired setpoint thanks to a PID controller that It has programmed. It has established a communication between the PID controller programmed in LabVIEW and Arduino Due, the DAC that It has chosen after comparing it with another candidate. It has learned some basics of how the LightCrafter 4500 DMD works. The projected light is the composition of the lights of three LED’s, each of which has a certain on-time. The mirrors chose to be in on- or off-stages depending to the amount of intensity that we want for each colour.
