Do you think that your health or safety are at risk because of your work? A large European study on psychological and physical work demands

Throughout Europe there are relatively few statistics, gathered a national level, which deal specifically with the problem of violence at work. In the UK, the revised Reporting of Injuries. Diseases and Dangerous Occurrences Regulations (RIDDOR) 1995 now require that certain violent incidents are reported on a national basis. The criteria for reporting, which are entirely dependent on the physical outcome of incidents, are discussed. It is recommended that employing organizations should establish their own internal systems for reportmg and recording a wider range of violent, and potentially violent, incidents. These should then be used to inform risk assessment and risk management.     

On uniform approximation of Poisson variates by normal ones

In this paper the accuracy of the normal approximation to the Poisson is treated from the viewpoint of direct approximation of Poisson variables by normal ones. The conclusions that are derived on the accuracy of this approximation lead (among others) to very useful results on confidence limits for the mean of a linear combination of independent Poisson variables; these latter are employed in precise determination of the composition of a mixture of radioactive isotopes by means of a scintillation counter.     

A Method for Estimating Lifetime Cancer Risks from Limited Epidemiologic Data

Partly because of the poor quality of exposure information on humans, most lifetime carcinogenic risk assessments have been based on animal data. There are, however, surrogate measures for exposure that have not been fully utilized. One of these is duration of exposure where data on mean exposure levels are available. A method is presented for the use of such data, and the method is illustrated by developing a risk assessment from the available epidemiologic literature on gasoline and kidney cancer. This risk assessment is fairly consistent across studies and close to a risk assessment based upon an experiment with rats. While there needs to be much improvement in the quality of environmental data available to epidemiologists, it is possible that a number of risk assessments can be made from existing epidemiologic data and efforts directed away from extrapolation from animal data.     

Inequalities for linear combinations of gamma random variables

We study the behavior of the tail probabilities of weighted averages of certain independently and identically distributed random variables as the weights are varied. We show that the upper and lower tails are smallest when all the weights are equal. Our results apply to exponential, chi-squared, gamma, and Weibull random variables.     

Child Protection,Public Services and the Chimera of Market Force Efficiency

The different agencies and professions that contribute towards child protection services have all recently had to begin to take account of the impact of market forces on their activities, yet detailed consideration of the consequences of this are slow to emerge. This article begins to consider these changes for child protection services. Having briefly described the child protection systems in England and Wales, it looks at the theoretical underpinning to the market forces approach which has become a significant ideological position in respect of public services in the UK and increasingly throughout the world. The article then considers the impact of a market forces approach on the organization of child protection services in relation to coordination versus fragmentation, profit versus professionalism, planning versus short-termism, and cooperation versus competition. It concludes that the argument that a market forces approach to child protection will lead to greater efficiency in relation to protecting children is a chimera. The article is thus of relevance for the different professions who contribute to child protection services in all countries where a market approach to public welfare is being suggested or implemented.
