Commuting accidents of Spanish professional drivers: when occupational risk exceeds the workplace
2019
Background. Work traffic accidents are an issue both in Spain and all over the world, and specific evidence on commuting accidents is scarce. Even though both industrial safety and welfare have been improved during the last decades, the commuting accidents rate is growing worldwide. Purpose. The aim of this study was to examine and describe the characteristics of commuting traffic crashes of Spanish professional drivers. Materials and methods. For this cross-sectional study, commuting accidents suffered by drivers during the last 12 years were analyzed. Crossed and heatmap-based analyses were performed in order to establish patterns and driver-based differences among commuting crashes. Resu…
The self-reported stress and stressors in tram and long-haul truck drivers
2022
Work stress may compromise professional drivers’ health and driving capacity. Differences between driver groups in terms of on-duty stress are understudied. Therefore, we examined self-reported stress (Stockholm University Stress Scale) of shift-working tram and long-haul truck drivers (n = 75) across 2–3 weeks. Furthermore, stressors were self-reported retrospectively and categorised as related to the job, driving conditions, personal, or other causes. Stress levels were generally low, but moderate to high stress (≥6) was more frequently reported among the tram drivers. Stressors related to the job (54%) and driving conditions (19% of all shifts) were frequently reported among the tram and…
Parents’ Willingness and Perception of Children’s Autonomy as Predictors of Greater Independent Mobility to School
2019
The present study aimed to examine the factors associated with different forms of independent mobility (IM) to school (IM one way and IM both ways) according to their parents&rsquo
Freedom and Redistribution
2012
In this paper we study the determinants of peopleís attitudes toward income inequality and their economic consequences. We argue that an individualís atti- tudes toward inequality depend upon the extent of freedom of choice and control over life outcomes he enjoys. We construct a two-stage empirical model where people Örst choose the level of income transfers and then their optimal level of ef- fort. We Önd that the higher the extent of an individualís free choice and control over life outcomes, the greater the probability that he supports larger income di§erences as incentives for individual e§ort. We also show that this relationship determines important consequences for the individualís w…

Mitigating the Climate Change Impacts of Aviation through Behavioural Change
2020
Aviation plays a crucial role for economic development and social welfare, but at the same time it also significantly contributes to climate change. Therefore, if the industry wants to follow the same growth path as it has in the past, it will need to mitigate its environmental impacts more seriously or it may otherwise face regulatory restrictions. The current literature has discussed five mitigation strategies. These are technological changes, market-based changes, operational changes, regulatory changes and behavioural changes. While several authors have regarded behavioural changes as the measure with the greatest mitigation potential, it is also the measure that has received far less a…
La consapevolezza professionale del docente: resilienza e autoregolazione.
2016
Il contributo si inserisce all’interno del Progetto di Rilevante Interesse Na- zionale (PRIN, 2010/2011) dal titolo “Successo formativo, inclusione e coe- sione sociale: strategie innovative, ICT e modelli valutativi” (Coordinatore Scientifico Nazionale del Programma di Ricerca Prof. Gaetano Domenici), con particolare riferimento all’autovalutazione della consapevolezza del docente. L’autoregolazione consapevole è il processo che, avvalendosi di strumenti di ‘’self-assessment’’ permette di adottare comportamenti più efficaci nella vita personale e professionale. La consapevolezza dello scopo da perseguire promuove la capacità di effettuare scelte e compiere decisioni e, conseguen- tement…
A Self-Contained Electro-Hydraulic Cylinder: Modeling, Control Design, Simulation and Experimental Validation
2018
Master's thesis Mechatronics MAS500 - University of Agder 2018 In the constant effort to improve the efficiency of hydraulic systems, the pressure drop over hydraulic valves has been one of the major obstacles. In the Self-Contained Electro-Hydraulic Cylinder, the directional valve and the hydraulic power unit have been replaced by a bi-directional axial piston pump and a Permanent Magnet Synchronous Motor. Actuation of the cylinder is performed by controlling the direction of rotation and the velocity of the motor. Originally the purpose of this project was to: "Design a proper control algorithm for an existing novel selfcontained electro-hydraulic cylinder, implement it on the main boom o…
Seismic stratigraphy of upper Quaternary shallow-water contourite drifts in the Gulf of Taranto (Ionian Sea, southern Italy)
2018
Abstract The occurrence of articulated seafloor morphology over continental shelf-upper slope environments, may result in a significant change in the patterns and intensity of basin-scale thermohaline circulation during eustatic sea-level fluctuations. These changes may cause, in turn, erosion, deposition and/or transport of sediments at the seafloor, to form shallow-water contourite drifts. Here we investigate this process in the NW sector of the Gulf of Taranto (Ionian Sea) during and following the Last Glacial Maximum (LGM), by integrating multibeam bathymetric data, ultra-high resolution seismic-reflection data and gravity core data. Sea level fall caused subaerial exposure of the summi…
