For this dataset, scientific peer-reviewed articles by Tampere University researchers from the years 2020 and 2021 were extracted from the TUNICRIS. A random sample of 40 percent was taken from the listed 4,922 publications according to faculties and years. There were 2,085 analyzed articles, i.e. more than 42 percent of the total number. To find Data Availability Statements, articles were opened one by one and searched for mentions of research data and its availability. For each article, it was written down whether DAS existed and where in the article it was located. From the contents of DAS, information about data availability, location, openness and possible restrictions on use was written down. Dataset also includes information about the journals and publications taken from TUNICRIS. The prevalence of DAS and data openness were examined in relation to different variables. Tampere University faculty information has been removed from the dataset. Related slides: https://doi.org/10.5281/zenodo.7655892 Related article (in Finnish): Toikko, T., & Kylmälä, K. (2023).
