LISS panel - In the Face of Mediated Distant Suffering: An Experimental Study on the Impact of Proximity and Agency on Audience Responses to Humanitarian Crisis

This questionnaire aims to answer the research question: How are compassion, perceived similarity and moral responsibility affected by the reported proximity and resilience of the victim in news representations of distant suffering?Suggestions for data usage: The data files are accessible via CentERdata.

Municipalities as enablers in urban experimentation

In the light of increasing urban challenges, municipalities are developing and advancing new forms of governing. One such example is ‘urban experimentation’, a process where city-based innovation processes are initiated to test solutions that – if deemed successful – are intended to be scaled up with the ambition to leverage a broader urban sustainability transition. Research on experimental governance has shown that municipalities can play various roles in these processes, including the role as enabler. The article contributes to the literature on the roles of public actors in urban experimentation on sustainability challenges by advancing understanding of the less studied ‘enabler’ role. We probe the politics of enabling by focusing on the policy instruments employed by municipalities. Our aim is to provide deeper insights into the everyday work of urban administrations when they act in the ‘enabler’ role. One particular approach of urban experimentation is Urban Living Labs (ULL), and this paper analyses ULL that address sustainability challenges. Along the four dimensions of nodality, authority, treasury, and organisation, we identify the politics of enabling in four ULL examples from Sweden and the Netherlands

Ribosomal deficiencies in Diamond-Blackfan anemia impair translation of transcripts essential for differentiation of murine and human erythroblasts

Diamond Blackfan Anemia (DBA) is associated with developmental defects and profound anemia. Mutations in genes encoding a ribosomal protein of the small (e.g. Rps19) or large (e.g. Rpl11) ribosomal subunit are found in over half of these patients. The mutations cause ribosomal haploinsufficiency, which reduces overall translation efficiency of cellular mRNAs. We reduced expression of *Rps19* or *Rpl11* in mouse erythroblasts and investigated mRNA polyribosome association, which revealed deregulated translation initiation of specific transcripts. Among these were *Bag1*, encoding a Hsp70 co-chaperone, and *Csde1*, encoding an RNA binding protein, both expressed at increased levels in erythroblasts. Their translation initiation is cap-independent and starts from an internal ribosomal entry site (IRES), which appeared sensitive to knock down of Rps19 or Rpl11. Mouse embryos lacking Bag1 die at embryonic day E13.5 with reduced erythroid colony forming cells in the fetal liver, and low Bag1 expression impairs erythroid differentiation in vitro. Reduced expression of Csde1 impairs proliferation and differentiation of erythroid blasts. Protein but not mRNA expression of *BAG1* and *CSDE1* was reduced in erythroblasts cultured from DBA patients. Our data suggest that impaired IRES-mediated translation of mRNAs expressed at increased levels in erythroblasts contributes to the erythroid phenotype of DBA. 3 biological replicates of erythroblasts treated with different shRNA were used for polyribosomal sucrose gradients; RNA was extracted from gradients in 2 samples - mRNA associated with polyribosomes (poly) and the rest (sub)
