Saccadic peak velocity as an alternative index of operator attention: A short review

IntroductionAutomation research has identified the need to monitor operator attentional states in real time as a basis for determining the most appropriate type and level of automated assistance for operators doing complex tasks.ObjectiveThe development of a methodology that is able to detect on-line operator attentional state variations could represent a good starting point to solve this critical issue.ResultsWe present a short review of the literature on different indices of attentional state and discuss a series of experiments that demonstrates the validity and sensitivity of a specific eye movement index: saccadic peak velocity (PV). PV was able to detect variations in mental state while doing complex and ecological tasks, ranging from air traffic control simulated tasks to driving simulator sessions.ConclusionThis research could provide several guidelines for designing adaptive systems (able to allocate tasks between operators and machine in a dynamic way) and early fatigue-and-distraction warning systems to reduce accident risk.     

L’habilitation des salariés : le rôle du supérieur et des collègues

Organizational initiatives to empower employees have limited success if they are supported only by top managers. The goal of this study is to examine how two actors in the workers’ proximal social environment, the supervisor and colleagues, contribute to employee empowerment. A questionnaire study was conducted with a sample of 418 workers relying both on psychological and behavioral self-report measures of employee empowerment. Multiple regressions revealed that contributions from the supervisor and colleagues are distinct, additive and interact in a synergic way to increase employee empowerment. These results suggest that it is important to foster favorable conditions in the workers’ proximal social environment to instill employee empowerment.     

Behavioural Change Techniques used in road safety interventions for young people

IntroductionDeath and injury from road traffic is a public health problem worldwide and accordingly there is substantial interest and investment in developing interventions to change road user behaviour. Alongside this, there is growing awareness of the need to evaluate interventions and to identify the most effective mechanisms by which behaviour can be changed. Progress has been hindered due to lack of a common taxonomy with which to define specific techniques used in attempts to change behaviour.ObjectiveBehavioural Change Techniques (BCTs) have been successfully deployed to change a range of different health behaviours. This paper defines a series of BCTs that can be applied in the road safety setting and asks which ones are found in road safety interventions for young road users?MethodAbraham and Michie (2008) identified twenty-six techniques used in behavioural change interventions. These BCTs, plus one other adapted from forensic psychology, are classified into nine groupings. Six educational road safety interventions commonly used in the UK with pre-drivers and young, novice drivers are characterised in terms of the BCTs they employ.ResultsOnly a small subset of BCTs are employed in most of the interventions. They concentrate primarily on increasing awareness of the risks associated with a particular behaviour, and the severity of the potential adverse consequences.ConclusionRecommendations are given for improving the effectiveness of road safety interventions for young people including young, novice drivers by increasing the range of BCTs deployed.     

Can sleep habits predict driver behaviour?

IntroductionThe role of sleep hygiene (those factors that promote or disrupt effective sleep) on human performance was examined.ObjectiveThe study investigated the relationship between sleep hygiene and crash involvement.MethodMeasures of sleep hygiene and crash involvement were considered for a sample of over 6000 drivers.ResultsIt was found that poorer sleep hygiene was associated with younger age and greater crash involvement. The association between sleep hygiene and crash involvement remained when age and risk taking had been taken into account.ConclusionPoor sleep hygiene is associated with poorer performance as measured by crash involvement.     

Implementation of automatic speed enforcement: Covariation with young drivers’ reported speeding behaviour and motivations

IntroductionSpeeding represents one of the main causes of road crashes worldwide, particularly among young drivers who are over-represented in road-crash statistics. For promoting road safety in France, an automatic speed enforcement (ASE) system was introduced late 2002.ObjectiveIn order to examine its efficiency on speeding and its motivations, we compared young drivers’ intentions and beliefs about speeding between the introduction of ASE (T1) and its completion in 2005 (T2) via a large survey based on the extended Theory of Planned Behaviour (TPB). We assumed the introduction of the ASE would covariate with a reduction in intention to speeding between T1 and T2 and a change in the extended TPB factors according to gender and driving experience.MethodOne thousand one hundred and ninety-two young participants (49.7% men) divided into novice, beginner, and more-experienced drivers filled in a questionnaire based on the extended TPB about their driving behaviour and history at T1 and 24 months later (T2).ResultsMen, beginner and more-experienced drivers expressed more intention to speeding within the next 12 months at T1 and showed a higher decrease in intention between T1 and T2 as compared to women and novice drivers. The extended TPB accounted for 59% of the variance in the decrease of the intention to speeding. Its main predictors were: lower perceived behavioural control over speeding, less social pressure, lower perceived similarity with the prototypical deviant driver, and higher comparative optimism. Secondly, slightly more positive behavioural beliefs and more negative outcome evaluations predicted this decrease.ConclusionPractical implications of the findings for road safety are discussed.     

Organisation du travail,stress et conséquences en milieu universitaire

The objective of this study is to show that the organization of work, appearing in a cultural context marked by inequity, and raising the symptoms of stress, has an adverse impact on the functioning of Cameroonian universities. From a random probability sample of 287 university teachers were selected. Relative to the French version of the organizational factors Karasek and Siegrist questionnaire and inventory-based stress symptoms questionnaire were administered to them. The analysis method was statistical results and hypotheses were tested with multiple regression. All hypotheses are confirmed.This research raises awareness of mental health, if it is not supported, can further contribute to weaken higher education in Cameroon.     

Contraintes temporelles et qualité du travail dans l’activité des soignants

This article investigates the relationships between care activity and temporal constrains. The main objective is to understand the constrain effects on care givers activity. It is aimed at understanding the effects of the requirements on care givers activity. A research-action of eighteen month was conducted within a residential establishment for older dependent people and studied the activity of thirty four care givers. Our theoretical frame associates both work clinic and ergonomics. Investigations method combined both observation and interviews. The analysis of the care givers activity shows the effects of the organizational constrains on the activity. The care givers activity focuses on time organization rather than care. Finally, the quality of work is impaired, the work looses its sense and misses its primary objectives.     

Analyse d’un modèle théorique de la conception dimensionnelle du narcissisme pathologique : incidences probables sur le leadership organisationnel

The purpose of this case study is to examine the appropriateness of the dimensional model of pathological narcissism developed by Roche, Pincus, Lukowitsky, Ménard and Conroy (2013). The exploration was essentially focused on decompensatory segment (failure of maladaptive self-enhancement strategies) of this model. By using a longitudinal research design, the results, although fragmentary, isolated a positive relationship between the two dimensions – grandiosity and vulnerability – of pathological narcissism. This positive relationship exists both in compensatory segment (use of maladaptive self-enhancement strategies) and in decompensatory segment of the model.
