Development and validation of the Spanish hazard perception test

Objective: The aim of the current study is to develop and obtain validity evidence for a Hazard Perception test suitable for the Spanish driving population. To obtain validity evidence to support the use of the test, the effect of hazardous and quasi-hazardous situations on the participants’ Hazard Prediction is analysed and the pattern of results of drivers of different driving experience: learner, novice and expert drivers and re-offender vs. non-offender drivers, is compared. Potentially hazardous situations are those that develop without involving any real hazard (i.e., the driver didn’t actually have to decelerate or make any evasive manoeuvre to avoid a potential collision). The current study analysed multiple offender drivers attending compulsory re-education programmes as a result of reaching the maximum number of penalty points on their driving licence, due to repeated violations of traffic laws. Method: A new video-based hazard perception test was developed, using a total of 20 hazardous situation videos plus 8 quasi-hazardous situation videos. They were selected from 167 recordings of natural hazards in real Spanish driving settings

El contacto entre las zonas de Ossa Morena y Sudportuguesa. Características y significado de la banda metamórfica de Aracena, en su sector central entre Aroche y Aracena (Huelva)

El contacto entre las zonas de Ossa Morena y Sudportuguesa está subrayado por la banda metamórfica de Aracena. Las características principales de esta región del macizo Ibérico pueden considerarse desde distintos puntos de vista: litológico, estructural, metamórfico, magmático, geoquímica, isotópico y experimental, y así se presentan en este artículo. La banda metamórfica de Aracena está dividida en dos dominios principales: el dominio oceánico está formado por metabasitas derivadas de un MORB (las metabasitas de Acebuches) y por un antiguo prisma de acrección. El dominio continental incluye gneises y migmatitas alumínicos, rocas de silicatos cálcicos, gneises leucocráticos, mármoles, anfibolitas, intrusiones sin/post-tectónicas de noritas ricas en Mg (con afinidad boninítica), así como rocas intrusivas post-tectónicas de composición ácida a básica. Las metabasitas de Acebuches sufrieron, en primer lugar, un metamorfismo de alta temperatura/baja presión que, en la actualidad, presenta un gradiente metamórfico invertido, y que estaba relacionado con un cabalgamiento vergente al SO. El pico térmico asociado a este evento metamórfico muestra un gradiente de edad, de forma que las edades más antiguas han sido obtenidas en el extremo oeste. La mitad inferior de la pila metabasítica de Acebuches fue afectada posteriormente por una deformación milonítica y un retrometamorfismo asociados a la zona de cizalla Sudibérica. Cuatro fases de deformación dúctil han sido definidas en el dominio continental: la fase CD-D1 estuvo relacionada con la generación de pliegues recumbentes de escala kilométrica. La fase CD-D2 se puede asociar a un colapso extensional, y es contemporánea con un metamorfismo de alta temperatura/baja presión que afectó al dominio continental y generó diversos complejos migmatíticos. La fase CD-D3 produjo pliegues simétricos verticales, mientras que la fase CD-D4 dio lugar a cabalgamientos vergentes al sur a los que se asociaron pliegues de propagación.Las principales características de la banda metamórfica de Aracena se interpretan como el resultado de la evolución de un punto triple de tipo fosa-fosa-dorsal. De acuerdo con el modelo propuesto, la interacción entre la dorsal y la zona de subducción dio como resultado la formación de una ventana astenosférica bajo el margen continental cabalgante, lo cual provocó el ascenso de la astenosfera y el consecuente rebote térmico. Esta unión triple migro a lo largo del margen continental hacia el este, lo que generó un cinturón metamórfico de alta temperatura/baja presión en el contacto entre las zonas de Ossa Morena y Sudportuguesa

May the NAO index be used to forecast rain in Spain?

This paper studies the influence of the North Atlantic Oscillation (NAO) on monthly, seasonal and annual precipitation regimes in continental Spain. The data used for this study include the monthly rain series of 325 meteorological stations distributed homogeneously over the study zone, and the monthly NAO indices from 1961 to 1998. A total of 5525 rain series were employed for the analysis. Simple and multiple linear correlations were established between these variables in different combinations. The main aim was to check whether monthly, seasonal or annual precipitation data could be predicted using earlier precipitation data and the NAO index. The geographical areas where the stations have shown a statistically significant correlation have been represented on maps. The results differ depending on the correlation, but, in general, the best results have been found in the fall and winter months. Finally, a practical application of the method was carried out in the Ebro Valley and it was observed that the combination of the NAO index for spring and summer and the precipitation registered in those two seasons may be useful to forecast rain in the fall.Este trabajo estudia la influencia de la Oscilación del Atlántico Norte (NAO) en el régimen de precipitaciones mensuales, estacionales y anuales de la España Peninsular. Para ello se han utilizado los datos mensuales de precipitación de 325 estaciones pluviométricas repartidas homogéneamente y los índices mensuales del índice NAO desde 1961 a 1998; se han usado un total de 5525 series de precipitación. El estudio se ha realizado mediante correlaciones lineales simples o múltiples entre estas variables utilizando diferentes combinaciones. Se trata de ver si se podría predecir la precipitación mensual, estacional o bien anual a partir de datos previos de precipitación y del índice NAO. Se han representado espacialmente las zonas geográficas cuyos observatorios manifiestan una correlación estadísticamente significativa. Los resultados difieren del tipo de correlación elegido, pero en general los mejores resultados se encuentran en los meses de invierno. Por último, se ha aplicado esta metodología al Valle del Ebro y se ha observado que una combinación del índice NAO de primavera y verano, junto con la precipitación registrada en esas dos estaciones podría ser útil para predecir la precipitación de otoño.publishe

Care of peripheral intravenous catheters in three hospitals in Spain: Mapping clinical outcomes and implementation of clinical practice guidelines

BACKGROUND: Peripheral intravenous catheters (PIVCs) are the most widely used invasive devices worldwide. Up to 42% of PIVCs are prematurely removed during intravenous therapy due to failure. To date, there have been few systematic attempts in European hospitals to measure adherence to recommendations to mitigate PIVC failures. AIM: To analyse the clinical outcomes from clinical practice guideline recommendations for PIVC care on different hospital types and environments. METHODS: We conducted an observational study in three hospitals in Spain from December 2017 to April 2018. The adherence to recommendations was monitored via visual inspection in situ evaluations of all PIVCs inserted in adults admitted. Context and clinical characteristics were collected by an evaluation tool, analysing data descriptively. RESULTS: 646 PIVCs inserted in 624 patients were monitored, which only 52.7% knew about their PIVC. Regarding PIVC insertion, 3.4% (22/646) patients had at least 2 PIVCs simultaneously. The majority of PIVCs were 20G (319/646; 49.4%) and were secured with transparent polyurethane dressing (605/646; 93.7%). Most PIVCs (357/646; 55.3%) had a free insertion site during the visual inspection at first sight. We identified 342/646 (53%) transparent dressings in optimal conditions (clean, dry, and intact dressing). PIVC dressings in medical wards were much more likely to be in intact conditions than those in surgical wards (234/399, 58.7% vs. 108/247, 43.7%). We identified 55/646 (8.5%) PIVCs without infusion in the last 24 hours and 58/646 (9.0%) PIVCs without infusion for more than 24 hours. Regarding PIVC failure, 74 (11.5%) adverse events were identified, all of them reflecting clinical manifestation of phlebitis. CONCLUSIONS: Our findings indicate that the clinical outcome indicators from CPG for PIVC care were moderate, highlighting differences between hospital environments and types. Also, we observed that nearly 50% of patients did not know what a PIVC is

Innovation in Early music festivals. domains, strategies and outcomes

This chapter takes an in-depth look at innovation in cultural festivals, in particular in early music festivals, which is a type of festival aimed at a generally local and minority audience. It identifies and analyses types of innovations, the strategies used by early music festivals to innovate and the results of these innovations in the framework of a collaboration with the European Early Music Network, whose members, festival directors, agreed to participate in the survey designed for this purpose. Different types of product, production and pre-production process, marketing and communication innovations are identified but also maintain traditional products and communication channels for their most loyal audience. The analysis shows that early music festivals engage in a range of innovations and employ a meaningful combination of innovation strategies with diverse stakeholders. Innovation efforts have led to several intangible and tangible improvements, including increased prestige and bigger and more diverse audiences. Although some of the innovations identified are common to other cultural festivals, many product innovations depend on musicology research; therefore, similar to other science-based sectors, relationships with researchers are very important

Defining risk factors associated with difficult peripheral venous Cannulation: A systematic review and meta-analysis

Peripheral venous catheterization is a common technique in hospitals which is not always successful, resulting in multiple punctures and degradation of the vessels. This scenario, which we have termed 'difficult peripheral venous access', is associated to delays in care, obtention of samples or diagnosis, as well as a higher use of central catheters. This study intends to identify risk factors associated to the incidence of 'difficult peripheral venous access' in adults at hospital. We designed a systematic review of published studies (protocol PROSPERO 2018 CRD42018089160). We conducted structured electronic searches using key words and specific vocabulary, as well as directed searches in several databases. After validity analysis, we selected 7 studies with observational methodology. We found great variability in the definition of 'difficult peripheral venous access' and in the variables proposed as risk factors. Statistically significant factors through studies include demographic and anthropometric variables (gender, Body Mass Index), as well as medical and health conditions (diabetes, renal insufficiency, parenteral drug abuse, cancer chemotherapy), together with variables related to the vein or vascular access (vein visibility and palpability, vessel diameter, previous history of difficulty). Some studies have also considered variables related to the professional performing the technique. Meta-analyses were carried out for gender and obesity as potential risk factors. Only obesity appeared as a statistically significant risk factor with OR of 1.48; 95% CI (1.03 to 1.93; p = 0.016). Methodological heterogeneity prevented the development of further meta-analyses. It is essential to design future studies with diverse hospital populations, in which a wide selection of potential risk factors can be studied in a unique analysis. Our work identifies the most relevant variables that should be included in those studies

NGC 6067: A young and massive open cluster with high metallicity

© 2017 The Authors. NGC6067 is a young open cluster hosting the largest population of evolved stars among known Milky Way clusters in the 50-150 Ma age range. It thus represents the best laboratory in our Galaxy to constrain the evolutionary tracks of 5-7M⊙ stars. We have used high-resolution spectra of a large sample of bright cluster members (45), combined with archival photometry, to obtain accurate parameters for the cluster as well as stellar atmospheric parameters.We derive a distance of 1.78 ± 0.12 kpc, an age of 90 ± 20 Ma and a tidal radius of 14.8 -3.2+6.8 arcmin. We estimate an initial mass above 5700M⊙, for a present-day evolved population of two Cepheids, two A supergiants and 12 red giants with masses ≈6M⊙. We also determine chemical abundances of Li, O, Na, Mg, Si, Ca, Ti, Ni, Rb, Y and Ba for the red clump stars. We find a supersolar metallicity, [Fe/H]=+0.19 ± 0.05, and a homogeneous chemical composition, consistent with the Galactic metallicity gradient. The presence of a Li-rich red giant, star 276 with A(Li)=2.41, is also detected. An overabundance of Ba is found, supporting the enhanced s-process. The ratio of yellow to red giants is much smaller than 1, in agreement with models with moderate overshooting, but the properties of the cluster Cepheids do not seem consistent with current Padova models for supersolar metallicity

Léxico, sintaxis y semántica de algunos transpositores complejos

Al pie del cañón representa una locución prototípica, pues en ella no se puede suprimir, agregar ni cambiar ningún componente, ni morfológico ni léxico: *pie de cañón, *a los pies del cañón, *en el pie de cañón, *a la pata del obús…, sin que pierda un valor léxico, ‘con constancia’, que no resulta de la reunión sintáctica de pie y cañón. En la flor de la vida tiene al menos dos variables: de la edad, de su vida. Así que el estatuto de las locuciones es cuestión de grado. En a flor de piel la locución se reduce a a flor ‘en la superficie’, persistente en a flor de agua, de tierra, de suelo, etc., ya que estos sintagmas no solo pueden intercambiarse, sino que cada uno complementa la locución con su valor léxico de sintagma libre

Human African Trypanosomiasis in a Spanish traveler returning from Tanzania

Human African Trypanosomiasis (HAT) is a parasitic disease usually confined to endemic areas in sub-Saharan Africa, but it occasionally may occur among travelers, migrants, or expatriates. Although it is an uncommon diagnosis in returning travelers attending travel and tropical medicine clinics [1], the number of HAT diagnoses in travelers has been rising in recent years [2], most likely in connection with an increase of tourists visiting endemic areas and improved reporting systems. Trypanosoma brucei is the etiological agent of HAT, and is transmitted by tsetse flies of the genus Glossina. Two species can cause the disease: T. brucei gambiense in West and Central Africa (g-HAT) and T. brucei rhodesiense (r-HAT) in Eastern and Southern Africa. The disease usually presents in two stages: a first or hemolymphatic stage, where the parasite is located in the lymphatic system and blood; and a second or meningo-encephalitic stage, which occurs when trypanosomes penetrate the central nervous system

AB0689 The importance of the sun. Vitamin D and spondyloarthritis: our experience in a third level hospital

[EN] Vitamin D plays an important role in the pathogenesis of autoimmune diseases, so that it has been shown that an adequate level is associated with a lower risk of developing this group of entities as well as a lower severity of them. Specifically, in spondyloarthritis (SpA) the deficiency has been associated with greater aggressiveness and greater radiological progression.S
