Conceptualization of the acidification theory in Swedish environmental research

Abstract

The aim of the present study was to describe and analyse the process of formulating the acidification theory in the Swedish research community. The empirical material was limited to articles written by Swedish researchers during the period 1950–1989 and published in international scientific journals utilizing a peer-review system. A model was developed to represent what Swedish researchers have regarded as the core of the acidification theory. Guided by the developed model, a qualitative content analysis of the scientific articles was conducted; i.e., we examined how central components and causal relationships of the theory have been explained and discussed. It should be emphasized that the present article describes an investigation of science itself (i.e., science in action) and is not an up-to-date review of acidification research. Our analysis revealed that some parts of the chain of evidence underlying the acidification theory were accepted before they were scrutinized by the scientific community and that the acidification complex was not conceptualized in accordance with the conceptualization of its various components. Actually, the acidification problem as a whole (i.e., the sum of all of its components) was not treated as a scientific theory that needed to be evaluated. This strongly indicates that the conceptualization was guided by factors that are generally, within the scientific community, considered to be external to the research process. There is no evidence that Swedish acidification research has adhered less stringently to scientific norms than environmental research in general has. Indeed, it is likely that such hidden patterns normally influence the conceptualization of science and we, therefore, conclude that the influence of factors that are not strictly a part of the research process must be further elucidated if the prerequisites and implications of research are to be clarified.Key words: scientific conceptualization, research process, acidification.
