Efectos del alcohol y conducción de vehículos: creencias y conductas de los jóvenes
2002
Los accidentes de tráfico son una de las principales causas de mortalidad entre I y 45 años (Generalitat de Catalunya, 1992 ; Montoro, et al., 1995). Numerosos estudios constatan que la siniestralidad viaria está relacionada con el consumo de alcohol (Montoro, 1997). Este problema es especialmente importante en la población joven y se incrementa durante las madrugadas de los fines de semana (Pedragosa,1995; Summala y Mikkola, 1994). Algunos estudios ponen de manifiesto la falta de información y/o conocimientos de muchos jóvenes sobre la normativa vigente que regula el consumo de alcohol de los conductores, así como de los efectos de esta droga sobre el consu¬midor (Reppetto y Senra, 1997; T…
Doctrina. La embriaguez y la toxicomanía como causas de despido disciplinario
2004
En el presente trabajo se aborda la embriaguez y la toxicomanía como causas de despi¬do improcedente en el Estatuto de los Trabajadores. A tal efecto se analizan las conduc¬tas básicas que dan pie a tal despido, los requisitos necesarios para que se produzca y la prueba de su incumplimiento. También se realiza una referencia a dichas causas de despido en los Convenios Colectivos.
Validación del subsistema de presentación de indicaciones del dispositivo ASFA Digital en el ferrocarril español
2012
En el año 2005, se inició un estudio para desarrollar el dispositivo ASFA digital en el que colaboraron Renfe, Adif, Invensys Rail Dimetronic, Ineco Tifsa y la Universidad de Valencia. En este proyecto, se desarrollaron las especificaciones técnicas y funcionales del sistema Embarcado ASFA Digital. La Universidad de Valencia participó en el diseño del subsistema de presentación de indicaciones del dispositivo ASFA Digital. La última etapa de este estudio es la validación del subsistema de presentación de indicaciones, objetivo de la presente tesis doctoral. Siguiendo las recomendaciones de estudios precedentes (Stevenson, et al., 2000), se ha dejado transcurrir cinco años, tiempo suficiente…
Propuesta de contextualizar la enseñanza de la física usando los accidentes de tráfico
2017
En esta comunicación presentamos una propuesta de uso de la física forense para contextualizar y mejorar su enseñanza. En concreto, se plantea un caso de accidente de tránsito, donde los estudiantes actuaban como peritos. Se diseña un cuestionario enfocado a conocer como los estudiantes aplican los conceptos de la mecánica clásica para resolver el caso. Para ello, se analizaron los cuestionarios diligenciados por 25 estudiantes de la asignatura de Física I en la Licenciatura de Ciencias Naturales y Educacion Ambiental. Los resultados muestran datos satisfactorios en relación a la comprensión de conceptos de mecánica clásica pero hay dificultad en la aplicabilidad de los mismos en contextos …
Cancer consequences of the Chernobyl accident in Europe outside the former USSR: A review
1996
The accident which occurred during the night of April 25-26, 1986 in reactor 4 of the Chernobyl nuclear power plant in the Ukraine released considerable amounts of radioactive substances into the environment. Outside the former USSR, the highest levels of contamination were recorded in Bulgaria, Austria, Greece and Romania, followed by other countries of Central, Southeast and Northern Europe. Studies of the health consequences of the accident have been carried out in these countries, as well as in other countries in Europe. This report presents the results of a critical review of cancer studies of the exposed population in Europe, carried out on the occasion of the 10th anniversary of the …
The guilty, the unlucky, or the unaware? Assessing self-reported behavioral contributors and attributions on pedestrian crashes through structural eq…
2020
Introduction: Recent literature suggests that the causation of pedestrians' crashes and the contribution of safety-related behaviors within them may substantially differ compared to other road users. This study aimed to test the effect of individual factors and safety-related road behaviors on the self-reported walk- ing crashes suffered by pedestrians and, complementarily, to analyze the causes that pedestrians attrib- uted to the crashes they suffered as pedestrians during the previous five years. Method: For this cross- sectional research performed in Spain, data from a nationwide sample of 2,499 pedestrians from the 17 regions of the country were collected. Participants had a mean age o…
Integration of a radiation biomarker into modeling of thyroid carcinogenesis and post-Chernobyl risk assessment
2016
Strong evidence for the statistical association between radiation exposure and disease has been produced for thyroid cancer by epidemiological studies after the Chernobyl accident. However, limitations of the epidemiological approach in order to explore health risks especially at low doses of radiation appear obvious. Statistical fluctuations due to small case numbers dominate the uncertainty of risk estimates. Molecular radiation markers have been searched extensively to separate radiation-induced cancer cases from sporadic cases. The overexpression of the CLIP2 gene is the most promising of these markers. It was found in the majority of papillary thyroid cancers (PTCs) from young patients…
The effect of age on cognitive performance of frontal patients
2015
Age is known to affect prefrontal brain structure and executive functioning in healthy older adults, patients with neurodegenerative conditions and TBI. Yet, no studies appear to have systematically investigated the effect of age on cognitive performance in patients with focal lesions. We investigated the effect of age on the cognitive performance of a large sample of tumour and stroke patients with focal unilateral, frontal (n=68), or non-frontal lesions (n=45) and healthy controls (n=52). We retrospectively reviewed their cross sectional cognitive and imaging data. In our frontal patients, age significantly predicted the magnitude of their impairment on two executive tests (Raven's Advanc…
Dose-dependent expression of CLIP2 in post-Chernobyl papillary thyroid carcinomas
2015
Summary This study showed a clear dose-response relationship for the CLIP2 radiation marker in post-Chernobyl papillary thyroid carcinoma cohorts for young patients and hints to different molecular mechanisms in tumors induced at low doses compared to moderate/high doses.
Building Bridges for Innovation in Ageing: Synergies between Action Groups of the EIP on AHA.
2017
The Strategic Implementation Plan of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) proposed six Action Groups. After almost three years of activity, many achievements have been obtained through commitments or collaborative work of the Action Groups. However, they have often worked in silos and, consequently, synergies between Action Groups have been proposed to strengthen the triple win of the EIP on AHA. The paper presents the methodology and current status of the Task Force on EIP on AHA synergies. Synergies are in line with the Action Groups' new Renovated Action Plan (2016-2018) to ensure that their future objectives are coherent and fully connected. The …
