Abstract. Regularly occurring flood events do have a history in Santiago de Chile, the capital city of Chile and study area for this research. The analysis of flood events, the resulting damage and its causes are crucial prerequisites for the development of risk prevention measures. The goal of this research is to empirically investigate the vulnerability towards floods in Santiago de Chile as one component of flood risk. The analysis and assessment of vulnerability is based on the application of a multi-scale (individual, household, municipal level) set of indicators and the use of a broad range of data. The case-specific set of indicators developed in this study shows the relevant variables and their interrelations influencing the flood vulnerability in the study area. It provides a decision support tool for stakeholders and allows for monitoring and evaluating changes over time. The paper outlines how GIS, census, and remote sensing data as well as household surveys and expert interviews are used as an information base for the derivation of a vulnerability map for two municipalities located in the eastern part of Santiago de Chile. The generation of vulnerability maps representing the two different perspectives of local decision makers (experts) and affected households is exemplified and discussed using the developed methodology.

Positive attitudes and trust towards former adversaries facilitate reconciliation and peacebuilding. Both historical and current intergroup experiences such as intergroup contact and conflict predict intergroup attitudes and trust but no previous research has investigated the joint effects of these experiences. Therefore, we study the interplay of positive intergroup contact preceding conflict, negative experiences of the conflict, and positive intergroup contact following conflict. Drawing on social representations theory and using a multilevel design, we highlight the importance of both individual and collective experiences. We examine the effects of such experiences on intergroup attitudes and trust among a large sample of Greek Cypriots (N = 802) and Turkish Cypriots (N = 718) from 54 formerly ethnically mixed villages in the context of a protracted and frozen conflict in Cyprus. Present day individual contact related to more positive attitudes and higher trust regardless of past experiences of conflict or contact. Furthermore, past collective contact experiences predict more positive attitudes and higher trust, whereas past collective conflict experiences predicted more negative attitudes and lower trust. Finally, present-day contact closes the gap in trust between respondents with low and high past contact. Overall, both current and historical, and individual and collective experiences matter.

Eine Methode, um die Vertraulichkeit von Daten, die in statistischen Ämtern erhobenen werden, zu gewährleisten, ist das Ersetzen vertraulicher Werte durch synthetische Daten, die mittels multipler Imputation generiert werden. Es wird ein zweistufiges Verfahren zur Generierung der synthetischen Daten vorgestellt, das eine unterschiedliche Anzahl von Imputationen für unterschiedliche Variablen ermöglicht. Die Vorteile eines zweistufigen Verfahren liegen in der Reduzierung der Laufzeit bei der Berechnung, in der Verringerung des Risikos der Deanonymisierung, und in der Erhöhung der inferentiellen Genauigkeit. Es wird beschrieben, wie das zweistufige Verfahren bei der Generierung eines Public-Use-Files des IAB-Betriebpanels zur Anwendung kommt. (IAB)
