In the paper "Organizing knowledge syntheses: A taxonomy of literature reviews. Knowledge in Society, 1, (104-126)" of Cooper H.M. he describes a taxonomy of literature reviews. Inside of this taxonomy he assumes that the reviewer of the literature has a position regarding the literature review itself. He argues that the reviewer could either be neutral or 'espousal of position'. While I have an assumption that it means something like voreingenommen I'm not able to find a source that proves this translation. Can anyone help me out?
Due to clarification reasons I added the taxonomy model, the highlighted fields are the fields which are applying for the work of a different author.
