Researchers from Europe, Australia, the US, Canada, and Japan provide 11 case studies on the inclusion, integration, and education of multi-ethnic people in host communities and countries, their transformative identity, and the psychological impact of these mobilizations. They discuss integration issues related to second-generation Mexican immigrants to the US, German-Turkish entrepreneurs in multi-ethnic neighborhoods in Berlin, immigrants and trade unions in Italy, and immigration policy toward Italian and other populations in Australia; identity in terms of the social construction of ethnic identity among young Kurdish immigrants in Turkey, young immigrants in Norway, Brazilian immigrants in different parts of the world, and young immigrants from Iran and the former Yugoslavia in Sweden; and education challenges, such as in Italy and at Canadian universities.
