Assessing the effect of school closures on the spread of COVID-19 in Zurich.

The effect of school closure on the spread of COVID-19 has been discussed intensively in the literature and the news. To capture the interdependencies between children and adults, we consider daily age-stratified incidence data and contact patterns between age groups which change over time to reflect social distancing policy indicators. We fit a multivariate time-series endemic-epidemic model to such data from the Canton of Zurich, Switzerland and use the model to predict the age-specific incidence in a counterfactual approach (with and without school closures).

Challenges Posed by Transnational Commercial Surrogacy: The Jurisprudence of the European Court of Human Rights.

There is little consensus between European States regarding the legal treatment of surrogacy in general and of transnational commercial surrogacy in particular. Against this background, the jurisprudence of the European Court of Human Rights (ECtHR) in this matter is of particular significance since it provides some common ground for the legal treatment of transnational commercial surrogacy in Europe. For this reason, the present paper will outline the development of the jurisprudence of the ECtHR on transnational commercial surrogacy, giving particular attention to the Mennesson and Labassee decisions, the Paradiso/Campanelli case, and the 2019 Advisory Opinion.

A landscape-scale assessment of the relationship between grassland functioning, community diversity, and functional traits.

Livestock farmers rely on a high and stable grassland productivity for fodder production to sustain their livelihoods. Future drought events related to climate change, however, threaten grassland functionality in many regions across the globe. The introduction of sustainable grassland management could buffer these negative effects.
