Verdeckte soziale Netzwerke im Nationalsozialismus
Die Entstehung und Arbeitsweise von Berliner Hilfsnetzwerken für verfolgte Juden
[Hidden Social Networks in National Socialism: The origins and working methods of Berlin assistance networks for persecuted Jews]
Why did people help Jews hide from the Nazis? This study examines interactions between helpers and aid recipients using the methods of social network research. Based on six Berlin case studies, the author looks at the social determinants for willingness to help, trust formation, network effects, and the daily practice of providing help from the perspectives of helpers and aid recipients.
