Flüchtlinge und Gewalt: Vorstellung des Datensatzes zu fluchtbezogenen Sicherheitsvorfällen

International organizations and research methods: an introduction

“…Examples of descriptive statistics are, for instance, the median age of Syrians seeking refugee protection in the European Union or the average monthly trade flow between the United States and China. Causal inference provides estimates of the relationship between two variables, such as the intensity of human rights violations and the number of refugees (Neumayer 2005;Moore and Shellman 2006), or the extent to which displacement contributes to the spread of violence (Salehyan and Gleditsch 2006;Bohnet, Cottier, and Hug 2018;Bohnet and Rüegger 2019). Causal inference makes it thus possible to determine whether a hypothesized relationship between two variables exists.…”

The security implications of transnational population movements: A meta-analysis

“…At the same time, anecdotal evidence and recent studies show that news about terrorist attacks can trigger negative views of immigrants among the general public (Finseraas, Jakobsson and Kotsadam 2011;Legewie 2013;Schu ¨ller 2016). However, although there is a large quantitative literature examining whether international refugees and migrants crossing borders are associated with more insecurity in the form of, for example, a higher risk of civil conflict or interstate disputes (Salehyan and Gleditsch 2006;Salehyan 2008), terrorism (Milton, Spencer and Findley 2013;Bove and Bo ¨hmelt 2016;Dreher, Gassebner and Schaudt 2017), fighting between groups (Bartusevi cius and Gleditsch 2019; Bo ¨hmelt, Bove and Gleditsch 2019), or one-sided violence (Fisk 2018;Bohnet and Ru ¨egger 2019), these scientific studies using quantitative methods are diverse and focus on different outcomes (albeit the same underlying latent concept), making it difficult to obtain a rigorous overview of the genuine impact transnational population flows have on insecurity.…”
