Modelling safety climate in the prediction of levels of safety activity

1998

Abstract This study examined the architecture of the relationships between components of organizational safety climate, including employee attitudes to safety issues and perceptions of the work environment, and related this to self-reported levels of safety activity. Data were collected from a large multinational manufacturing organization by questionnaire. A total of 915 valid questionnaires were returned and formed the basis for structural equation modelling and subsequent analyses. These data showed that a common structure, or architecture, of attitudes to safety issues and perceptions of the work environment could be constructed that explained levels of safety activity. The strength of …

Exploiting Semantic Trajectories Using HMMs and BIM for Worker Safety in Dynamic Environments

2020

International audience; Understanding dynamic behaviors of moving objects using positioning technologies for construction safety monitoring is still an open research issue. One task; that is a small subset in the widespread field of objects dynamics is the enrichment of the location data of users with the semantic information for studying their mobility patterns in the context of the environment. However, incorporating the semantics related to the environment gets complex in case of the dynamic construction sites where the site spaces are kept evolving with time. For instance, new walls and infrastructure supports are added often on sites, while others are detached. Similar situations open …

A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness

2018

The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…

Masonry structures subjected to tsunami loads: Modeling issues and application to a case study

2020

Abstract Tsunamis are among the most dangerous natural disasters for coastal areas experiencing tsunami hazard. One of the major concerns in the assessment of strategies for the risk mitigation is to estimate vulnerability of structures and infrastructures. However, reliable approaches for the evaluation of the structural capacity under tsunami loads are nowadays not always available for all the types of structures, especially masonry. On this aim, the paper deals with the modeling issues of 3D masonry structures subjected to tsunami loads and the effect on the structural behavior of different modeling approaches. First, a brief state of the art on the available studies is presented regardi…

Have information technologies forgotten pedestrians?

2018

Worldwide, pedestrians make up close to half of all motor-vehicle related fatalities but disproportionally little of the research in Information Technologies (IT) in general and Intelligent Transportation Systems (ITS) in particular has aimed at pedestrian safety improvements. This paper analyses and compiles three different ways so that IT and ITS can be used in order to improve mobility and safety of pedestrians in urban spaces: (a) for contacting and/or being localized, (b) for guidance (leading/navigating), (c) for alerting or informing of a danger. The aim is to categorize recent experiences where ITS can improve pedestrians’ mobility and safety so that new ideas based on ITS will be d…

The methodology for active testing of electronic devices under the radiations

2018

The methodology, developed for active testing of electronic devices under the radiations, is presented. The test set-up includes a gamma-ray facility, the hardware board/fixtures and the software tools purposely designed and realized. The methodology is so wide-ranging to allow us the verification of different classes of electronic devices, even if only application examples for static random access memory modules are reported.

[Loyauté des transactions sur un marché relatif aux attributs de croyance : une analyse appliquée aux produits agro-alimentaires]

2001

International audience; Après avoir décliné la typologie des caractéristiques des produits en termes d'attributs de recherche, d'expérience et de croyance, les auteurs soulignent les mécanismes susceptibles d'assurer l'efficacité des transactions marchandes. Afin de cerner les enjeux liés à la loyauté des transactions dans le cas des attributs de croyance, ils montrent à l'aide d'un jeu simple, le caractère crucial des phases de définition, de vérification et de signalement, ces dernières nécessitant généralement l'intervention d'agents extérieurs à la transaction marchande.

Dynamic Shakedown Sensitivity Analysis by Means of a Probabilistic Approach

2017

The shakedown limit load multiplier problem for elastic plastic structures subjected to a combination of fixed and seismic loads is treated. In particular, reference is firstly made to the unrestricted dynamic shakedown theory. The relevant seismic load history is modeled as a repeated one and, with reference to classically damped structures, appropriate modal analyses are utilized. With the aim of evaluating the reliability of the results arising from the application of the cited theory, a recent probabilistic approach is also utilized. This approach adopts the Monte Carlo method in order to define the necessary seismic acceleration histories and finally compute the related shakedown limit…

A job-exposure matrix for research and surveillance of occupational health and safety in Spanish workers: MatEmESp

2013

BACKGROUND: In this study we describe a general-population job-exposure matrix (MatEmESp) for Spanish workers covering the period 1996-2005. METHODS: The Finnish job-exposure matrix (FINJEM) provided the default value estimates for occupational exposure to chemical, physical and biological agents. These estimates were adapted to Spanish working conditions by local experts. Spanish surveys were used to obtain exposure estimates for ergonomic and psychosocial risk factors. Employment and socio-demographic conditions for Spanish workers were obtained from the Spanish National Statistics Institute. RESULTS: MatEmESp provides a large amount of national and occupation-specific data on the major o…
