Health impact assessment (HIA) on a strategic level focuses on the broad determinants of health. However, the evidence with regard to the health impacts is often necessarily 'soft'. The example of a health impact review on national housing policy in the Netherlands shows that HIA can be effective even in the absence of hard data. Strategies used to overcome the problem of not having hard data a...

The theory of electron impact ionization of oneand two-electron atoms has advanced significantly in the past two years. This paper will summarize the progress that the members of our research center have contributed to.
