Ergonomic Indicators and Physical Workload Risks in Food Production and Possibilities for Risk Prevention
2021
The food industry is the most important and largest manufacturing industry in Latvia, producing almost a third of all manufacturing output. Employees in a food production enterprises are exposed to a variety of ergonomic risks: monotonous work movements that can be repeated up to 1000 times a day, overloads that exceeds 30 kg in lifting and moving operations, forced working postures, fast work pace. The aim of the study was to identify ergonomic indicators related to physical load for packers in one medium-sized company producing potato starch in Latvia. When summarizing the results of the survey on burden-lifting rates, it should be noted that, in a shift, 30% of packers lift the burden fr…
Post-license Education for Novice Drivers: Evaluation of a Training Programme implemented in Spain
2006
Abstract Introduction This study evaluated the implementation of a second phase training program for novice drivers in Spain, which puts the primary focus of the training on the higher hierarchical levels of driver behavior. Method Two hundred and sixty-three participants took part throughout the study, which was implemented as an experimental design with the test and control groups assessed before and after the one day safety training. Measurement of the impact of the training program focused on the participants' self-evaluation and self-reporting of some driving behavior indicators related to accident risk. Results Data analysis showed a change in the expected direction in the scale relat…
Childhood trauma and substance use underlying psychosis: a systematic review
2020
[EN] Background: Schizophrenia spectrum disorders (SSD) are mental diseases caused by a combination of genetic susceptibility and a number of environmental factors. Among these factors, the role of traumatic events suffered in childhood, as well as that of substance use, have been of particular research interest. Objectives: To conduct a systematic review to clarify whether there is an interaction between childhood trauma and substance use related to the diagnosis or symptoms of SSD. It was also the objective of this review to collate the associations that may exist between the three variables of the study (trauma, substance use and psychosis). Methods: We conducted a systematic search resu…
To See Oneself as Seen by Others
2019
Abstract This article develops a new phenomenological analysis of the interpersonal motives and structure of shame. I pursue the argument that shame is rooted in our desire for social affirmation and conditioned by our ability to see ourselves as we appear to others. My central thesis is that shame is what we feel when, due to some trait or action of ours, we come to perceive ourselves as fundamentally despicable and non-affirmable. By showing how our urge for affirmation fuels and informs our self-perception in shame, the analysis provides a better understanding of the simultaneously interpersonal and personal character of shame. Furthermore, it sheds new light on some central aspects of s…
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…
