A new dataset titled ‘Orientation Systems in Public Transportation and the Cultural Dimension of Uncertainty Avoidance – A Behavioral and Semiotic Analysis of Selected European Cities,’ authored by Dr. Kamil Olender of the University of Wroclaw, has been published in the QDA. The dataset contains materials produced under the ‘Miniatura’ grant of the National Science Center, Poland. The study evaluated orientation systems in public transportation in the context of the identity elements of the city and region. The theoretical background of the project was based on Geert Hofstede’s concept of cultural dimensions.
