- The concept of disability-adjusted life years (DALYs) has rapidly gained in popularity in health policy, and considerable research resources are being allocated to this field. Proponents of DALYs suggest that the measure can be used both as a "gross domestic product of health" and to help in setting priorities in health policy. This study investigates the usefulness of DALYs and contends that DALYs, as the measure is currently understood, cannot be used for either of these two purposes. The DALYs procedure does not produce a useful measure of population health, and its use in priority setting is ethically questionable.

- Establishment is a key concept in urban forestry but it is currently inconsistently defined and measured. Thus, several different methods are being used to determine establishment success but their consequences and applications are rarely discussed. With this paper we would like to stimulate an increased discussion regarding these concepts both in relation to a theoretical definition but also to their practical use. The problem was approached through an experiment using sweet cherry (Prunus avium L.) and northern red oak (Quercus rubra L.) trees and the most common methods used for determination of establishment success. The trees were studied during the first three years after transplant and the association between the different measuring methods was examined. A Principal Component Analysis showed that terminal and lateral shoot length were strongly correlated, and that midday- and pre-dawn shoot water potential, and stomatal conductance were strongly correlated. We developed an index for nightly recovery of water status, which showed that terminal shoot growth was not related to nightly recovery until the third year after transplanting. Our results suggest that successful tree establishment is determined differently depending on which method is used for determination but that the differences might decrease with time. The lack of a firm definition of the term establishment may complicate communication, both within the scientific community and in practice.
