Producing SI-traceable reference values for Cd, Cr and Pb amount contents in polyethylene samples from the Polymer Elemental Reference Material (PERM…
2000
The present paper describes the certification of the amount content of Cd, Cr and Pb in two different polyethylene materials within the third phase of the Polyethylene Elemental Reference Material (PERM) project. The analytical procedure to establish the reference values for Cd, Cr and Pb amount contents in these materials is based on isotope dilution mass spectrometry used as a primary method of measurement. Cd and Pb were measured with inductively coupled plasma-mass spectrometry and Cr with positive thermal ionization-mass spectrometry. The decomposition of the polymer matrix was carried out using a high pressure asher. Reference values for amount content, traceable to the SI-system, hav…
Prevention of occupational injuries: moral hazard and complex agency relationships
2004
This paper exploits the results of agency theory with the aim of contributing a new viewpoint and a form for analysis of the current functioning of the occupational injury and disease section of the French Social Security system in its mission of providing incentives for prevention. After outlining the organization and specific features of insurance against occupational risks, an initial level of analysis highlights the presence of moral hazard in relations between insurer and company and between company and employee. A second level of analysis with the appeal to complex agency relationship models, multitask model and third-party model, is necessary to take into account the consequences for…
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…
Work–family conflict and enrichment from the perspective of psychosocial resources: Comparing Finnish healthcare workers by working schedules
2014
Abstract We examined work–family conflict (WFC) and work–family enrichment (WFE) by comparing Finnish nurses, working dayshifts (non-shiftworkers, n = 874) and non-dayshifts. The non-dayshift employees worked either two different dayshifts (2-shiftworkers, n = 490) or three different shifts including nightshifts (3-shiftworkers, n = 270). Specifically, we investigated whether different resources, i.e. job control, managers' work–family support, co-workers' work–family support, control at home, personal coping strategies, and schedule satisfaction, predicted differently WFC and WFE in these three groups. Results showed that lower managers' work–family support predicted higher WFC only among …
Linking empowering leadership to safety participation in nuclear power plants: a structural equation model.
2012
Abstract Introduction Safety participation is of paramount importance in guaranteeing the safe running of nuclear power plants. Method The present study examined the effects of empowering leadership on safety participation. Results Based on a sample of 495 employees from two Spanish nuclear power plants, structural equation modeling showed that empowering leadership has a significant relationship with safety participation, which is mediated by collaborative team learning. In addition, the results revealed that the relationship between empowering leadership and collaborative learning is partially mediated by the promotion of dialogue and open communication. Conclusions The implications of th…
Soccer players' fitting perception of different upper boot materials.
2016
[EN] The present study assessed the influence of upper boot materials on fitting perception. Twenty players tested three soccer boots only differing in the upper boot material (natural calf leather, natural kangaroo leather and synthetic leather). Players reported fitting perception and preference on specific foot areas using a perceived fitting scale. Ratings were averaged for every foot area. Repeated measures ANOVA was used to analyze the differences between boots. The kangaroo leather boots were perceived tighter and closer to the preferred fitting in general fitting, metatarsals area and instep area. The synthetic leather boots were perceived as the loosest and as the most distant boot…
Safety signs on agricultural machinery: Pictorials do not always successfully convey their messages to target users.
2015
This study investigated the extent to which a sample of Italian users comprehended safety pictorials used on agricultural machinery. A questionnaire with 12 safety pictorials was administered to 248 users of agricultural machinery. For each of the pictorials, the participants were asked to select the most appropriate description of four written choices. The investigated safety pictorials were, in general, not well comprehended. Two different classes of participants were identified, each with a different level of comprehension. The participants with better comprehension were characterized by the regular use of agricultural machinery and frequent previous exposure to pictorials. The need for …
Socio-economic inequalities in mortality due to injuries in small areas of ten cities in Spain (MEDEA Project).
2011
Abstract Objectives To analyse socio-economic inequalities in mortality due to injuries among census tracts of ten Spanish cities by sex and age in the period 1996–2003. Methods This is a cross-sectional ecological study where the units of analysis are census tracts. The study population consisted of people residing in the cities during the period 1996–2003. For each census tract we obtained an index of socio-economic deprivation, and estimated standardized mortality ratios using hierarchical Bayesian models which take into account the spatial structure of the data. Results In the majority of the cities, the geographical pattern of total mortality from injuries is similar to that of the soc…
Accident ahead? Difficulties of drivers with and without reading impairment recognising words and pictograms in variable message signs
2017
A timely and accurate acquisition of the information provided by variable message signs (VMS) can be crucial while driving. In the current study, we assess the difficulties of adults with dyslexia acquiring the information shown in VMS and provide evidence to discuss the controversial use of pictograms as potential countermeasures. Twenty-two adults with dyslexia and 22 matched controls completed a simulated driving session. The legibility of 12 VMS was assessed, including six text messages (e.g. "ACCIDENT") and six single pictograms (e.g. the icon for "accident ahead"). On average, participants with dyslexia started reading text messages when they were closer to the VMS. In addition, while…
