Science-policy in environmental and health risk assessment: if we cannot do without, can we do better?

How can empirical evidence of adverse effects from exposure to noxious agents, which is often incomplete and uncertain, be used most appropriately to protect human health? We examine several important questions on the best uses of empirical evidence in regulatory risk management decision-making raised by the US Environmental Protection Agency (EPA)'s science-policy concerning uncertainty and variability in human health risk assessment. In our view, the US EPA (and other agencies that have adopted similar views of risk management) can often improve decision-making by decreasing reliance on default values and assumptions, particularly when causation is uncertain. This can be achieved by more fully exploiting decision-theoretic methods and criteria that explicitly account for uncertain, possibly conflicting scientific beliefs and that can be fully studied by advocates and adversaries of a policy choice, in administrative decision-making involving risk assessment. The substitution of decision-theoretic frameworks for default assumption-driven policies also allows stakeholder attitudes toward risk to be incorporated into policy debates, so that the public and risk managers can more explicitly identify the roles of risk-aversion or other attitudes toward risk and uncertainty in policy recommendations. Decision theory provides a sound scientific way explicitly to account for new knowledge and its effects on eventual policy choices. Although these improvements can complicate regulatory analyses, simplifying default assumptions can create substantial costs to society and can prematurely cut off consideration of new scientific insights (e.g., possible beneficial health effects from exposure to sufficiently low 'hormetic' doses of some agents). In many cases, the administrative burden of applying decision-analytic methods is likely to be more than offset by improved effectiveness of regulations in achieving desired goals. Because many foreign jurisdictions adopt US EPA reasoning and methods of risk analysis, it may be especially valuable to incorporate decision-theoretic principles that transcend local differences among jurisdictions.

Approaches to environmental noise policy in Australia

Australia is a federation of six states and two territories. Legislation for environmental noise is the responsibility of each of the Australian states and territories. The Federal government has the responsibility for national issues such as aircraft noise and also to encourage harmonisation of the legislation and regulations among the states and territories. For some decades there has been a document on environmental noise produced by Standards Australia but it is up to each state or territory to call up part or all of this Standard. For general environmental noise some states use comparison with background as the criteria while others define the criteria levels based on land use zones. Both approaches have their advantages and drawbacks. This paper will compare and contrast the different legislation and regulations and discuss the issue of 'cross border' disputes.

The politics of exclusion:institutions and immigration policy in contemporary Germany

Immigration is one of the most sensitive issues of modern European politics. Nowhere is this more the case than in Germany, as a result of its history and the sheer scale of immigration it has experienced since 1945. Yet despite this background, Germany's immigration, residence and citizenship policy has been more restrictive when compared to that of many other countries; indeed, official policy long maintained that Germany was not a 'country of immigration'. But why has this been the case? The politics of exclusion provides a new analytical perspective on immigration in Germany, tracing the country's immigration and citizenship policy since the Second World War. The book argues that institutional politics are central to understanding why Germany's policy structures have experienced only incremental change over the past 20 years, and have remained comparatively restrictive. With its lively and accessible style, the book will appeal to advanced scholars and students of immigration and Germany.

Divergent traditions, converging responses: immigration and integration policy in the UK and Germany

This contribution argues that although the UK and Germany have different historical traditions of immigration and integration, which continue to define policy responses in specific areas, recent developments show a distinct convergence in each country's policy goals and adopted policy instruments in this sector. It contends that both endogenous (demographic and skills shortages, integration deficits) and exogenous (influx of asylum seekers, terrorism) variables can be identified for this convergence. It also pinpoints the European Union as a growing source both of convergence and policy coordination in this field.
