This monograph was composed on the basis of a fully revised paper-based dissertation, consisting of a binding text, three journal articles and one book chapter. Chapters III-VI, each of them single articles, were reproduced in accordance with the conventions of the respective publisher. Thus, there are inconsistencies with e.g., title capitalization, because the publishers provided different style sheets. Furthermore, footnote numbering was started anew each chapter, to mirror the original source. In line with the monographic format, the book contains only one single bibliography, in accordance with the conventions of the American Psychological Association ("APA 6th"). The same style sheet was used within the binding text.
