From job demands and resources to work engagement, burnout, life satisfaction, depressive symptoms, and occupational health

2016

This study investigated the cross-lagged associations between work engagement and burnout, and life satisfaction and depressive symptoms, their demands (i.e., workload) and resources (i.e., servant leadership, self-efficacy, resilience) and relationships with occupational health outcomes (i.e., recovery, number of mental health diagnoses, workaholism). This study is a part of an ongoing Occupational Health Study in which 1 415 employees (586 men, 829 women) were followed twice during two years 2011–12 through their occupational health services. The participants filled in a questionnaire on their work engagement, burnout symptoms, well-being, personal and work environmental resources and dem…

Combined Innovation Policy: Linking Scientific and Practical Knowledge in Innovation Systems

2012

New research indicates that firms combining the science-based STI (Science, Technology, Innovation) and the experience-based DUI (Doing, Using, Interacting) modes of innovation are more efficient when it comes to improving innovation capacity and competitiveness. With regard to innovation policy, the STI mode calls for a supply driven policy, typically aimed to commercialise research results. The DUI mode suggests a demand driven policy approach, such as supporting the development of new products or services to specific markets. This paper analyses how the two types of innovation policy and the two innovation modes can be combined in regional innovation systems. The analysis builds on studi…

Safety Evaluation of α-Lipoic Acid Supplementation: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Clinical Studies

2020

Alpha-lipoic acid (ALA) is a natural short-chain fatty acid that has attracted great attention in recent years as an antioxidant molecule. However, some concerns have been recently raised regarding its safety profile. To address the issue, we aimed to assess ALA safety profile through a systematic review of the literature and a meta-analysis of the available randomized placebo-controlled clinical studies. The literature search included EMBASE, PubMed Medline, SCOPUS, Google Scholar, and ISI Web of Science by Clarivate databases up to 15th August 2020. Data were pooled from 71 clinical studies, comprising 155 treatment arms, which included 4749 subjects with 2558 subjects treated with ALA an…

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…

HUMAN SAFETY PERFORMANCE IN HIGH RELIABILITY ORGANIZATIONS: THE CASE OF THE NUCLEAR INDUSTRY

2018

Over the last few decades, the study of safety in high reliability organizations has not paid enough attention to the human role and its contribution to a reliable operation. Therefore, the literature about human safety performance is scarce and disjointed. The present paper integrates the existing knowledge on workers’ safety performance in high risk industries, specifically in the nuclear industry. In order to do this, we provide a literature review in which the concept of “safety performance” is clarified, and at the same time, we present the most recent research studies and models on this concept.

Calibration of microscopic traffic simulation models for evaluating operation and safety performance at roundabouts

Safety and immunomodulatory effects of three probiotic strains isolated from the feces of breast-fed infants in healthy adults: SETOPROB study.

2013

We previously described the isolation and characterization of three probiotic strains from the feces of exclusively breast-fed newborn infants: Lactobacillus paracasei CNCM I-4034, Bifidobacterium breve CNCM I-4035 and Lactobacillus rhamnosus CNCM I-4036. These strains were shown to adhere to intestinal mucus in vitro, to be sensitive to antibiotics and to resist biliary salts and low pH. In the present study, a multicenter, randomized, double-blind, placebo-controlled trial with 100 healthy volunteers in three Spanish cities was carried out to evaluate the tolerance, safety, gut colonization and immunomodulatory effects of these three probiotics. Volunteers underwent a 15-day washout perio…

Evaluation of the vibrations transmitted to the hand-arm system in the use of portable harvesters for olives

2017

The use of portable harvesters in olives harvesting is presently widely diffused in Sicily, south Italy, both to reduce the costs of production and to assure the olive oil quality. Nevertheless, it's well known that the use of such tools may involve risk of exposure to vibration transmitted to the hand-arm system which is a potential cause of muscular/skeletal pains, and specific pathologies such as Hand-Arm Vibration Syndrome (HAVS), Vibration-Induced White Finger (VWF) and Carpal Tunnel Syndrome (CTS). The aim of this study was to assess the level of exposure to vibration transmitted to the hand-arm system of the operators during the use of portable harvesters for olives. Two different co…

The Relationship Between Safety Attitudes and Occupational Accidents

2011

This research provides empirical evidence on the relationships between employee attitudes to safety issues and accident indicators in a Spanish context. The research attempts to review to what degree those attitudes reflect a collective, or shared, climate for safety within a number of organizations. Data were gathered from workers in a number of industries in Valencia (Spain) by questionnaire. A total of 1,234 valid questionnaires were completed and formed the basis for subsequent analysis. Analysis of the attitude dimensions found a similar structure to that found in previous research in other countries, as well as identifying those dimensions shared within groups, more likely to represe…
