Job stress and emotional exhaustion at work in Spanish workers: Does unhealthy work affect the decision to drive?
2020
Objectives The purpose of this study was to assess the relationships among the following elements: unhealthy work indicators (job stress and emotional exhaustion at work), the decision to drive (or not), and driving crashes suffered by Spanish workers. Methods For this cross-sectional study, a full sample of 1,200 Spanish drivers (44% women and 56% men) was used, their mean age being 42.8 years. They answered a questionnaire divided into three sections: demographic and driving-related data; burnout, job stress, and life stress; and self-reported road behaviors and driving safety indicators. Results Overall, 41.6% of drivers reported emotional exhaustion at work. Furthermore, 80.2% of the pa…
Influence of sexual appeal in roadside advertising on drivers' attention and driving behavior.
2019
Sexual appeals are widely used in advertising to attract consumers' attention. It has already been proved that they influence the addressee's cognitive processing, which in turn raises the question if sexual appeals may pose a serious threat for road safety when used in roadside advertising. Three studies were designed to answer this question. Study I was a nationwide survey (N = 1095) which revealed that drivers subjectively perceive sexual contents in roadside advertising as distracting and dangerous. Study II was a modified version of the Attentional Network Test (N = 1063) which proved that in cognitive tasks reaction time increases in line with the sexual content of advertisements. Stu…
Can't simply roll it out: Evaluating a real-world virtual reality intervention to reduce driving under the influence.
2020
Driving under the influence (DUI) increases the risk of crashes. Emerging technologies, such as virtual reality (VR), represent potentially powerful and attractive tools for the prevention of risky behaviours, such as DUI. Therefore, they are embraced in prevention efforts with VR interventions primed to grow in popularity in near future. However, little is known about the actual effectiveness of such DUI-targeting VR interventions. To help fill the knowledge gap, this study explored the effects of one VR intervention as delivered in the real world. Using pre and post test design, including an intervention group (n = 98) and a control group (n = 39), the intervention evaluation examined you…
Innovation cooperative systems and structural change: An evolutionary analysis of Anecoop and Mondragon cases
2016
International audience; In a globalized world, clusters, or territorial production systems, need to evolve into innovation systems to retain their competitive advantages and be able to develop. This study analyzes the cooperative entrepreneurship model as a means of structural change for these clusters, constituting a third way between the private business way and the government-oriented way. Building on an evolutionist approach and a qualitative comparative methodology, the study analyzes two successful cooperatives: Mondragon and Anecoop. As a novelty, this article explains the innovation process from an institutional perspective, combining micro–meso–macro levels. The results confirm tha…
Hierarchical Self-Assembly of Halogen-Bonded Block Copolymer Complexes into Upright Cylindrical Domains
2017
Summary Self-assembly of block copolymers into well-defined, ordered arrangements of chemically distinct domains is a reliable strategy for preparing tailored nanostructures. Microphase separation results from the system, minimizing repulsive interactions between dissimilar blocks and maximizing attractive interactions between similar blocks. Supramolecular methods have also achieved this separation by introducing small-molecule additives binding specifically to one block by noncovalent interactions. Here, we use halogen bonding as a supramolecular tool that directs the hierarchical self-assembly of low-molecular-weight perfluorinated molecules and diblock copolymers. Microphase separation …
Mechanical properties of pultruded glass fiber reinforced plastic after freeze–thaw cycling
2012
The use of pultruded fiber-reinforced plastics in civil infrastructure requires the long-term prediction of their mechanical properties, which should be based on understanding and estimating the processes in the structure under action of aggressive environmental factors: humidity and freeze–thaw cycles. This article reports on results of short-term exposure to severe freeze–thaw cycling in the temperature range from –30°C to 20°C of polyester-based glass fiber reinforced plastic both dry and wet. The effect of freeze–thaw cycling of flat specimens cut from I-beam pultruded profile was estimated by use of three-point-bending tests and dilatometric investigation in the temperature range from…
PALERMO 2030: The Mediterranean City in Transition
2019
The Mediterranean cities in particular, thanks to the concentration of complexity / diversity and multiplicity are the most suitable places to start a transition so as to turn the contradictions of the urban system into an opportunity for transformation. The process of knowledge based on the observation of the cities becomes fundamental in a context such as that of Palermo, which is characterized by growing levels of complexities and uncertainty. In this context a critical process has been initiated just to recognize the city of Palermo and its main characters. Starting from this process several priority elements and different alternatives have been identified with continuous reviewing just…
On How to Build SDI Using Social Networking Principles in the Scope of Spatial Planning and Vocational Education
2011
Several ways how to build a spatial data infrastructure usable for spatial planning domain exist. It must be said that today the area of spatial planning is under the influence of the European INSPIRE directive. It is necessary to spread an awareness about how to build this infrastructure in terms of INSPIRE. The article describes the current ways how to build the spatial data infrastructure. Furthermore, a new approach - GeoPortal4everybody, based also on using of social networking principles is proposed. Next, the paper presents using of GeoPortal4everybody concept as a part of technological framework for vocational education partially developed in the SDI-EDU project. This project aims o…
Déplacements et mutations spatiales à Alger
2019
Algiers port and city’s exceptional history is driven by its remarkable site nestled on a rocky spur. Revealed.Yet this morphology constrained the urban growth of a city that could pretend joigning the ranks of large metropolis. During its history port and city relationship took multiple forms, frequently compatible yet sometimes divergent and even opposed, leading to inversing domination status of both actors. Algiers capital of a 40 million inhabitants state, has always been a laboratory of urban politics since the colonial era to the institutional constructions of independent Algeria, regardless of deficient statistical tools. However, the space in Algiers is confronted to great challeng…
Measurement uncertainty impact on simplified load flow analysis in MV smart grids
2018
This work is focused on the measurement uncertainty impact on load flow analysis in medium voltage (MV) distribution networks. In more detail, the paper presents the uncertainty evaluation of a simplified load flow algorithm, which is based on the load power measurements at each secondary substation and one voltage measurement at the slack bus (i.e. the voltage at the MV bus bars of the primary substation). To reduce the costs of the monitoring system, the load flow algorithm makes use of LV load power measurements for all the substations except those of MV users, where MV transducers are usually already installed. The uncertainties on the algorithm input quantities (load powers and slack b…
