The Russian threat and the consolidation of the West: How populism and EU-skepticism shape party support for Ukraine.

Support for Ukraine against Russian aggression has been strong across Europe, but it is far from uniform. An expert survey of the positions taken by political parties in 29 countries conducted mid-2023 reveals that 97 of 269 parties reject one or more of the following: providing weapons, hosting refugees, supporting Ukraine's path to European Union membership, or accepting higher energy costs. Where the perceived threat from Russia is most severe, we find the greatest levels of support for Ukraine.

Discovering cooperation: Endogenous change in international organizations.

Unlabelled: Why do some international organizations (IO) accrete delegated authority over time while in others delegation is static or declines? We hypothesize that the dynamics of delegation are shaped by an IO's founding contract. IOs rooted in an open-ended contract have the capacity to discover cooperation over time: as new problems arise these IOs can adopt new policies or strengthen collaboration in existing areas. This, in turn, triggers a demand for delegation.

Cell surface dynamics and cellular distribution of endogenous FcRn.

A major role for FcRn is the salvage of pinocytosed IgG and albumin from a degradative fate in lysosomes. FcRn achieves this by binding IgG in a pH-dependent manner in acidic endosomes and recycling it to the plasma membrane to be released at neutral pH. This is important in maintaining high serum IgG and albumin levels and has the potential to be exploited to modulate the pharmacokinetics of antibody-based therapeutics.
