Before the Covid 2019 pandemic the number of activities varied between 3000 and 4000 yearly. Since 2020 the number of activities has been around 1500 yearly.
The share of various activities has changed. Previously, visiting academic institutions and hosting an academic visitor were among the five most usual activities. As the figure shows, the number of physical visits to and from Aalto is still quite low. The number of all other activities is also lower than in the years before pandemic.
Many new subcategories of activities have been added to ACRIS to reflect changes in TENK CV and responsible research assessment. In addition, new keywords: promoting open science and promoting research integrity and ethics enable researcher to finetune their activities.
