In the authors' opinion, critically ill COVID-19 patients should be treated in an ARDS center provided that sufficient resources are available.Most small rodent populations in the world have fascinating population dynamics. In the northern hemisphere, voles and lemmings tend to show population cycles with regular fluctuations in numbers. In the southern hemisphere, small rodents tend to have large amplitude outbreaks with less regular intervals. In the light of vast research and debate over almost a century, we here discuss the driving forces of these different rodent population dynamics. We highlight ten questions directly related to the various characteristics of relevant populations and ecosystems that still need to be answered. This overview is not intended as a complete list of questions but rather focuses on the most important issues that are essential for understanding the generality of small rodent population dynamics. Awidespread assumption is that people learn certain ways of dealing with media in the course of their youth and adult life, which later make it difficult for them to develop new patterns of media usage. Beyond theoretical assumptions, there is alack of exploratory studies that investigate the conditions under which older people pick up new media technologies and integrate them into their everyday lives. From October 2019 to March 2020 a total of 16 semi-standardized individual interviews were carried out with people aged between 80 and 92years. The interviewees had learned to use adigital medium on their own in the past few years and had integrated this into their everyday lives. The interviewees appropriated new media in atargeted manner. It is noticeable that processes of appropriation were largely triggered by severe changes in living conditions. In addition, most of the interviewees learned how to use adigital medium because
