Changing driver behavior during floods: Testing a novel e-health intervention using implementation imagery
2021
Abstract We tested the efficacy of a novel implementation imagery intervention (N = 460) in promoting safer intentions regarding driving into floodwater post-intervention, and at a four-week follow-up using a pre-registered randomized controlled design. Results showed that the intervention reduced intentions and subjective norms regarding driving into floodwater. The control condition also improved on intentions and subjective norms, but the changes appeared to only be maintained at the follow-up for the intervention group and the between group difference at the follow-up was not significant based on our pre-specified cutoff level for statistical significance of 0.01. Results also indicated…
European Respiratory Society statement on sleep apnoea, sleepiness and driving risk
2021
Obstructive sleep apnoea (OSA) is highly prevalent and is a recognised risk factor for motor vehicle accidents (MVA). Effective treatment with continuous positive airway pressure has been associated with a normalisation of this increased accident risk. Thus, many jurisdictions have introduced regulations restricting the ability of OSA patients from driving until effectively treated. However, uncertainty prevails regarding the relative importance of OSA severity determined by the apnoea–hypopnoea frequency per hour and the degree of sleepiness in determining accident risk. Furthermore, the identification of subjects at risk of OSA and/or accident risk remains elusive. The introduction of off…
Quality control in the optical industry: From a work analysis of lens inspection to a training programme, an experimental case study
2007
A cognitive work analysis of quality inspection in the optical industry has been carried out in order to devise a training programme. The task concerned the inspection of high quality human eyeglass lenses. We conducted an experimental investigation of defect detection and acceptability decision-making tasks in 18 experts and novice inspectors. Detection and decision-making were investigated together and separately in two experimental sessions. We showed the effect of expertise on reaction times and errors, and we described the cognitive processes of novice inspectors. On the basis of the processing differences between the two groups, a training programme for new inspectors was devised and …
Validity of a Questionnaire for the Assessment of Work-related Musculoskeletal Symptoms and Physical Demands
2011
Fundamentos: En las intervenciones de ergonomía participativa es frecuente utilizar cuestionarios autoadministrados para obtener información acerca de los daños y riesgos ergonómicos percibidos por los trabajadores. El objetivo de este estudio es evaluar la validez de un cuestionario diseñado para su utilización en este tipo de programas. Métodos: Participaron 35 trabajadores voluntarios de diez empresas de Valencia y Alicante. El trabajo de campo se realizó en 2009. Se siguieron tres estrategias: análisis de repetibilidad en dos vueltas del cuestionario, comparación de las respuestas al cuestionario (primera vuelta) con la información obtenida mediante observación directa de los puestos de…

Embodied sound design
2018
Abstract Embodied sound design is a process of sound creation that involves the designer’s vocal apparatus and gestures. The possibilities of vocal sketching were investigated by means of an art installation. An artist–designer interpreted several vocal self-portraits and rendered the corresponding synthetic sketches by using physics-based and concatenative sound synthesis. Both synthesis techniques afforded a broad range of artificial sound objects, from concrete to abstract, all derived from natural vocalisations. The vocal-to-synthetic transformation process was then automated in SEeD, a tool allowing to set and play interactively with physics- or corpus-based sound models. The voice-dri…
Color memory in children
2008
The methods of simultaneous and memory color matching have been studied for a set of five Munsell color samples by 50 children, 25 boys and 25 girls (ranging in age from 9 to 11 years). By comparison between this group and one of 50 young adult observers, we can deduce the following: (a) In children, as in young adults, the mean CIELAB total color difference, ΔE*ab, in simultaneous color matching is lower than the ΔE*ab by memory color matching. (b) Children matched reference test worse than young adults for orange, bluish green (only boys and men) and yellow green (only girls and women). (c) While men remember, independently of age and delay time, violet reference test worse than women (P …

A Critical Interpretive Synthesis of the Literature Linking Music and Adolescent Mental Health
2013
There is a diverse literature that explores the relationship between youth, music, and mental health, with few attempts at systematic synthesis. This critical interpretive review included 33 studies published between 2000 and 2012 investigating the relationship between music and the mental health of young people, particularly targeting depression. An iterative methodology was used involving several layers of inductive analysis with the intention of generating an organizing framework that critically synthesized the available literature. The organizing framework highlights that decisions related to research design, assessment of health, and the nature of musical engagement have predictably i…
International survey of violence risk assessment practices
2016
International audience; Objective Mental health professionals are routinely called upon to assess the violence risk presented by their patients, frequently aided by structured instruments. Though surveys of risk assessment and management have been conducted, these efforts have been largely circumscribed to individual countries and have not compared the practices of members of different professional disciplines. Method A web-based survey was developed to examine the international use of structured instruments in the violence risk assessment process across five continents and to compare the perceived utility of such instruments by psychologists, psychiatrists, and nurses. The survey was trans…
