Footnote
1. The impact referred to in this section is primarily based on the observational results, which also correspond to the qualitative and quantitative research results that are presented in later sections. The observation was done in public and in a non-participation way. The five study groups were observed by four participants each time including the authors and two research assistants. Thus, each study group was observed twice on average. Observers prepared notebooks, digital voice recorders, and observational record forms to record the observations in order to gain a preliminary understanding of the study groups. After the observations, the researchers met to report, discuss, and coordinate their observational results.
