Schulz et al. 2007 contains texts that appear to overlap with previously published texts of different authorship. The overlapping material in the first image is highlighted in yellow. The two earlier texts (Besser, Gold) are not referenced anywhere in the article, and there are no quotation marks around the material. The overlap extends to the secondary literature in footnotes 2, 3, 4.
