TLDR
In this article, the authors combine an online panel survey with mobile tracking data to measure the actual usage of Germany's official contact tracing app and reveal higher uptake rates among respondents with an increased risk of severe illness, but lower rates among those with a heightened risk of exposure to COVID-19 pandemic.Abstract:
Digital contact tracing apps have been introduced globally as an instrument to contain the COVID-19 pandemic. Yet, privacy by design impedes both the evaluation of these tools and the deployment of evidence-based interventions to stimulate uptake. We combine an online panel survey with mobile tracking data to measure the actual usage of Germany's official contact tracing app and reveal higher uptake rates among respondents with an increased risk of severe illness, but lower rates among those with a heightened risk of exposure to COVID-19. Using a randomized intervention, we show that informative and motivational video messages have very limited effect on uptake. However, findings from a second intervention suggest that even small monetary incentives can strongly increase uptake and help make digital contact tracing a more effective tool.read more

Mitigating COVID-19 infection disease transmission in indoor environment using physical barriers
Chen Ren,Chang Xi,Junqi Wang,Zhuangbo Feng,Fuzhan Nasiri,Shi-Jie Cao,Shi-Jie Cao,Fariborz Haghighat,Fariborz Haghighat +8 more
TL;DR: This study provides a theoretical analysis for implementing physical barriers, as a low-cost mitigation strategy, subject to various height scenarios and investigation of their effectiveness in reducing the infection transmission probability.

Incentives can spur COVID-19 vaccination uptake.
TL;DR: In this article, the authors assess the effectiveness of three strategies to increase vaccine uptake, namely, providing freedoms, financial remuneration, and vaccination at local doctors, and find that all three strategies can increase vaccination uptake on the order of two to three percentage points (PP) overall and five PP among the undecided.

TL;DR: A mathematical model for infectiousness was developed to estimate the basic reproductive number R0 and to quantify the contribution of different transmission routes and the requirements for successful contact tracing, and the combination of two key parameters needed to reduce R0 to less than 1 was determined.

New Effect Size Rules of Thumb
TL;DR: In this article, recommendations to expand Cohen's (1988) rules of thumb for interpreting effect sizes are given to include very small, very large, and huge effect sizes, and the reasons for the expansion, and implications for designing Monte Carlo studies are discussed.
