Efficient and effective learning for safety from incidents

Learning from incidents is important for improving safety. Many companies spend a great deal of time and money on such learning procedures. The objectives of this paper are to present some early results from a project aimed at revealing weaknesses in the procedures for learning from incidents and to discuss improvements in these procedures, especially in chemical process industries. The empirical base comes from a project assessing organizational learning and the effectiveness of the different steps of the learning cycle for safety and studying relations between safety-specific transformational leadership, safety climate, trust, safety-related behavior and learning from incidents. The results point at common weaknesses in the organizational learning, both in the horizontal learning (geographical spread) and in vertical learning (double-loop learning). Furthermore, the effectiveness in the different steps of the learning cycle is low due to insufficient information in incident reports, very shallow analyses of reports, decisions that focus at solving the problem only at the place where the incident took place, late implementations and weak solutions. Strong correlations with learning from incidents were found for all safety climate variables as well as for safety-related behaviors and trust. The relationships were very strong for trust, safety knowledge, safety participation and safety compliance.     

Fatigue effects of noise on aeroplane mechanics

Subjective fatigue and reaction time performance were measured in a group of 24 aeroplane mechanics, during 1 week of high noise exposure and 1 week of low noise exposure. Subjective ratings were collected before and after each work day. On the last day of each week subjects also completed a reaction time task before and after work. The mechanics felt more sleepy and less energetic during the high noise week. This effect was most evident towards the end of the day and there was a build-up of the effect during the week. Reaction times were prolonged during the high noise week. Possible confounding factors are discussed and found to be less likely explanations of the effects.     

How philanthropy can alter our view of the past: a look at Colonial Williamsburg

The restoration of Colonial Williamsburg, Virginia, serves as an important study in the history of philanthropy in the United States. Williamsburg demonstrates how the investments of philanthropists such as the Rockefeller family can be used to subtly alter Americans' perceptions of their past. This manipulation resulted in the promotion of the Rockefellers' ideological interpretation of history at Williamsburg. This history stressed the role of Williamsburg as a monument to the ideals of Americanism: democracy, republicanism and individual achievement. Through times of domestic and international crisis, from the Red Scare of the 1920s through the Cold War of the 1950s, the Rockefeller family held up Williamsburg as a beacon to which Americans could look as a steadying force. In doing so, the Rockefellers created a past which never truly existed. They downplayed the roles of women and blacks, who were all but ignored in the early presentation of the town, in favour of the aristocrats of the age: George Washington, Thomas Jefferson and George Wythe. The presentation which emerged during the restoration's first half-century was one that failed to acknowledge the roles played by less prominent groups and over-accentuated the importance of a small minority of illustrious townspeople.     

Risk Perception and New Age Beliefs

This is a study of risk perception in relation to New Age (NA) beliefs, including traditional folk superstition and belief in paranormal phenomena, as well as use of alternative healing practices. Data were also obtained on trust dimensions and on personality and psychopathology variables, as well as religious involvement. It was found that four factors accounted for the investigated NA beliefs, which were termed higher consciousness beliefs, denial of analytic knowledge, traditional superstition, and belief in the physical reality of the soul. NA beliefs were strongly and positively related to religious involvement, and negatively to educational level. These beliefs were also positively related to maladjustment and to concerns over tampering with nature. In regression analyses, it was found that NA beliefs explained about 15% of the variance of perceived risk, and that the most powerful explanatory factors were higher consciousness beliefs and beliefs in paranormal phenomena. Traditional superstition and use of healing practices did not contribute to explaining perceived risk.     

Recurrence,eruptions, and a transnational turn: Three decades of strained relations between migrants to Norway and the Child Welfare Services

The relations between the Norwegian Child Welfare Services (CWS) and various migrant groups are notably strained. Numerous media accounts and a growing body of research reveal that many migrants to Norway fear the CWS. By combining quantitative and qualitative analyses of media accounts, this paper addresses the historical evolvement of such strained relations in Norway. Previous research has neglected this aspect. Findings show that migration issues related to the CWS have been topics of public debate in Norway for three decades, with foster care being a particularly intractable concern. With the onset of the decade beginning in 2010, however, matters have intensified and taken on transnational dimensions. In the discussion of our findings, we emphasize in particular how digital and social media have contributed to the recent changes.     

Alcohol and drug abuse among young adults who grew up in substitute care — Findings from a Swedish national cohort study

To what extent substitute long term care modifies intergenerational transmission of substance abuse has rarely been investigated. Using register data, we followed a national cohort born 1973–1985 consisting of 1012 national adoptees, 2408 former children from long term foster care, 348/846 environmental siblings of adoptees/foster children, and 952,935 majority population peers, from their 15th birthday to age 27–35. Using Cox regression, we calculated hazard ratios (HR) for hospital care and criminality associated with illicit drug/alcohol abuse, with adjustments for socio-demographic indicators of caring families, and substance abuse in caring and birth parents.     

Analogies for Helping Clinicians and Investigators Better Understand the Principles and Practice of Biostatistics

For the interaction between the biostatistician and the clinician or research investigator to be successful, it is important not only for the investigator to be able to explain biological and medical principles in a way that can be understood by the biostatistician, so, too, the biostatistician needs tools to help the investigator understand both the practice of statistics and specific statistical methods. In our practice, we have found it useful to draw analogies between statistical concepts and familiar medical or everyday ideas. These analogies help to stress a point or provide an understanding on the part of the investigator. For example, explaining the reason for using a nonparametric procedure (a general procedure used when the underlying distribution of the data is not known or cannot be assumed) by comparing it to using broad spectrum antibiotics (a general antibiotic used when the specific bacteria causing infection is unknown or cannot be assumed) can be an effective teaching tool. We present a variety of useful (and hopefully amusing) analogies that can be adopted by statisticians to help investigators at all levels of experience better understand principles and practice of statistics.     

Trainee programme reactions and work performance: the moderating role of intrinsic motivation

This study investigated the moderating role of intrinsic motivation on the relationship between trainee programme reactions and work performance among trainees enrolled in formal trainee programmes. The results from a cross-sectional survey among 114 trainees representing three Norwegian service organizations showed that the relationships between perception of the trainee programme and facets of self-reported work performance were positive only for trainees low in intrinsic motivation. Implications for practice and directions for future research are discussed.
