Trends in the Study of Cultural-Historical Phenomena on the Internet (based on a study of Russians' attitudes towards money).

Background: The development of information technologies has led to the intensification of sociocultural interaction, allowed the creation of new systems for storing and processing information, and provided space for users to share their opinions, ideas, and standpoints. Thus, the Internet has become a major social-humanitarian scientific space.

The Spread of COVID-19 in Russia: Immediate Impact on Mental Health of University Students.

Amid the spread of COVID-19, a study of mental health in university students from different regions of Russia ( = 3057) was undertaken during the period from April 9 to April 20, 2020. The results were compared to studies conducted earlier within a large-scale research project examining student mental health. Mental health indicators were analyzed during three different periods: long before the onset of the pandemic (period 1); in the early days of the spread of COVID-19 in Russia, though prior to the implementation of containment measures (period 2); during tough measures to contain the first wave of the pandemic (period 3).
