The measurement of accident-proneness
This paper deals with the measurement of accident-proneness. Accidents seem easy to observe, however accident-proneness is difficult to measure. In this paper I first define the concept of accident-proneness, and I develop an instrument to measure it. The research is mainly executed within chemical industry, and the organizations are pictured summarily. The instrument is validated in different ways with different outcomes. On the basis of these outcomes I conclude that the accident-proneness scale has only a limited validity, and each branch of industry probably requires another accident subscale. However for a comparison within chemical industry the instrument seems admissible.
Maternal health-related quality of life after induction of labor or expectant monitoring in pregnancy complicated by intrauterine growth retardation beyond 36Â weeks
Objective: Pregnancies complicated by intrauterine growth retardation (IUGR) beyond 36Â weeks of gestation are at increased risk of neonatal morbidity and mortality. Optimal treatment in IUGR at term is highly debated. Results from the multicenter DIGITAT (Disproportionate Intrauterine Growth Intervention Trial At Term) trial show that induction of labor and expectant monitoring result in equal neonatal and maternal outcomes for comparable cesarean section rates. We report the maternal health-related quality of life (HR-QoL) that was measured alongside the trial at several points in time. Methods: Both randomized and non-randomized women were asked to participate in the HR-QoL study. Women were asked to fill out written validated questionnaires, covering background characteristics, condition-specific issues and the Short Form (SF-36), European Quality of Life (EuroQoL 6D3L), Hospital Anxiety and Depression scale (HADS), and Symptom Check List (SCL-90) at baseline, 6Â weeks postpartum and 6Â months postpartum. We compared the difference scores of all summary measures between the two management strategies by ANOVA. A repeated measures multivariate mixed model wa
Authority structure and industrial accidents
This paper deals with the influence of organizational characteristics on safety. Accidents are
actually caused by individual mistakes. However the underlying causes of accidents are often
organizational. The general hypothesis is that the authority structure is a main cause of
accident-proneness within organizations. On one side, the most obvious model for a safe
organization would be the ideal-typical bureaucracy. On the other side, potential problems are
little flexibility and control is based on (lacking) knowledge. I discern hierarchy as a separate
element of bureaucracy, and distinguish different aspects of authority. The analysis shows
several significant correlations, and the distinction between control and management seems to
be of interest for safety.
Communication and industrial accidents
This paper deals with the influence of organizational communication on safety. Accidents are
actually caused by individual mistakes. However the underlying causes of accidents are often
organizational. As a link between these two levels - the organizational failures and mistakes - I
suggest the concept of role distance, which emphasizes the organizational characteristics. The
general hypothesis is that communication failures are a main cause of role distance and
accident-proneness within organizations. A general classification of communication is
presented, and safety communication and obstacles are distinguished. The analysis at various
levels does not falsify all my hypotheses, and several dimensions of communication seem to
be of interest for the safety.
