The DUALNETS project has carried out several activities to reach the aims of the project. First, to detect whether and how dual identifiers are recognized as dual identifiers, we conducted 27 semi-structured interviews with Dutch vocational school students. This gave us relevant insights into how young adults mentally construct the social relations in their school class and that it is very difficult for them to ascribe dual identities to their classmates. To further achieve this aim, we collected online survey data using experiments to examine (1) the role of the social context in which dual identifiers might be recognized as such, and (2) whether identity signals (religious symbols, national symbols, and high or low-status clothing) influence whether people with a migration background are seen as either members of the national majority and/or ethnic minority group. The images used in these surveys were created with AI and we experimentally tested if the effects of (not) mentioning this influenced the results. The first set of experiments has a principle acceptance for a journal as a registered report. Second, we have developed a new interactive software to collect (perceptions of) network data. The tool, named SICCEN (Software Interface for Collecting Complete and Egocentric Networks), was designed in co-creation with game design students of a vocational training program (the main target group of our research) and developed with an external programmer and with a programmer from our university. We piloted the tool in secondary school classes and demonstrated it to the social network community. The tool will be used for data collection in school classes in 2024/2025. Third, to determine when dual identifiers can(not) affect interethnic relations) we have published an academic article in which we find that while many adolescents with a migration background feel belonging to two cultural groups (dual identity), they are not seen as such by their peers. Most of their peers ascribe them only belonging to their ethnic minority group. Fourth, to uncover whether and how dual identifiers affect interethnic relations, we are writing a scientific article on the intergroup consequences of contact with dual identifiers. We are using newly collected population-based ego-centered network data from the Netherlands and existing complete network data from Germany. Additionally, to achieve this aim, we are writing an article on the role dual identifiers play in promoting inter-group relations in inter-ethnic school friendship networks. We aim to contribute theoretically to the literature by examining how dual identifiers' self-identification influences both their own preferences and others' preferences for friendship choices within inter-ethnic social networks. Fifth, we created a strong collaboration with the MBO Raad, which is a nationwide organization representing vocational schools in the Netherlands. They assist us with the big data collection in school classes in 2024/2025 and they will help us with the dissemination of our findings. Finally, we organized an academic workshop on dual identity and biculturalism.
