Risk Communication in The Netherlands: The Monitored Introduction of the EC "Post-Seveso" Directive

Implementation of article 8.1 of the EC-"Seveso" Directive (82/501/EC) is now under way in many countries in Europe. In The Netherlands, the implementation of the Directive started with a carefully monitored introduction of active information provision at two sites (Dordrecht and Elst). This introduction was supported by a multidisciplinary research group. This group helped to develop the risk communication program and also played a role in the evaluation of the program. This paper describes these processes and their evaluation. We will focus on the design of the risk communication programs and the effects of the programs on knowledge and attitudes of the local target groups. This effort and its results clearly started an institutional learning process involving governmental bodies at several organizational levels (local, regional, and national), and industrial organizations (individual firms and organizations of industries). Monitoring the design, the implementation, and the effects of active information provision proves an effective means to gain experience with the implementation of the Seveso Directive and could help to facilitate further implementation.     

Survey investigations of the hidden economy: Some methodological results

In 1982 the Netherlands Central Bureau of Statistics started large-scale survey research on the supply of hidden labour. As it was not known what type of survey would yield the best results, eight survey variants were tried out. They differed in the medium of communication between the researcher and respondent (face-to-face, mail and telephone) and in interview design (direct approach, gradual approach and ‘free-form’ conversation). Several criteria were used to assess the survey variants on their suitability for obtaining statistical information on the magnitude and structure of the hidden labour market. With respect to non-response and item non-response, face-to-face methods yielded the best results. In combating incorrect responses, a gradual introduction of the topic ‘hidden income’ is to be preferred.     

Exploring social constructions of followership: A qualitative study

This study adopts a qualitative approach to deconstruct the meaning of followership. Interviews were conducted with employees in various industries to examine how individuals socially construct their roles as followers and to explore followership schemas and contextual influences that relate to these constructions. Results suggest that while some individuals socially construct definitions around passivity, deference and obedience, others emphasize the importance of constructively questioning and challenging their leaders. With regard to personal qualities that are thought to make followers effective, major themes such as obedience, expressing opinions, and taking initiative were found to be most disparate across different groups of followers. Results also revealed that contextual factors may affect both followership constructions and behavior in the follower role. These findings have important implications regarding a need to examine the construct of followership in leadership research, as well as raise interesting possibilities for advancing an “expanded” view of leadership in organizations.     

How to take a penalty

When Rob Eastaway told friends he was embarking on a project to write a book about the maths of sport, they didn't hear the word "maths"-they heard "statistics". That, after all, is the most obvious interpretation. But, as he discovered, mechanics, geometry and even some mathematical history all play their part.     

Human Interindividual Variability in Parameters Related to Health Risks

This paper reviews existing data on the variability in parameters relevant for health risk analyses. We cover both exposure-related parameters and parameters related to individual susceptibility to toxicity. The toxicity/susceptibility data base under construction is part of a longer term research effort to lay the groundwork for quantitative distributional analyses of non-cancer toxic risks. These data are broken down into a variety of parameter types that encompass different portions of the pathway from external exposure to the production of biological responses. The discrete steps in this pathway, as we now conceive them, are:Contact Rate (Breathing rates per body weight; fish consumption per body weight)Uptake or Absorption as a Fraction of Intake or Contact RateGeneral Systemic Availability Net of First Pass Elimination and Dilution via Distribution Volume (e.g., initial blood concentration per mg/kg of uptake)Systemic Elimination (half life or clearance)Active Site Concentration per Systemic Blood or Plasma ConcentrationPhysiological Parameter Change per Active Site Concentration (expressed as the dose required to make a given percentage change in different people, or the dose required to achieve some proportion of an individual's maximum response to the drug or toxicant)Functional Reserve Capacity–Change in Baseline Physiological Parameter Needed to Produce a Biological Response or Pass a Criterion of Abnormal FunctionComparison of the amounts of variability observed for the different parameter types suggests that appreciable variability is associated with the final step in the process–differences among people in functional reserve capacity. This has the implication that relevant information for estimating effective toxic susceptibility distributions may be gleaned by direct studies of the population distributions of key physiological parameters in people that are not exposed to the environmental and occupational toxicants that are thought to perturb those parameters. This is illustrated with some recent observations of the population distributions of Low Density Lipoprotein Cholesterol from the second and third National Health and Nutrition Examination Surveys.
