The Productivity Effect of Public–Private Partnership
ABSTRACT Public–Private partnerships (PPPs) are often employed by public authorities to deliver infrastructure and public services through contracts bundling construction, operation, and maintenance over extended periods. Using a novel dataset covering the universe of Italian district heating plants (DHs) from 2007 to 2014, I show that PPP improves ...

Species Yet to Be Discovered Are More Threatened and Have Smaller Ranges
ABSTRACT Aim To assess whether newly described species are more likely to be threatened and have smaller ranges than known species. Location Global. Methods In this study, we focus on the timing of species acceptance. We compare two global taxonomic assessments of birds, mammals and amphibians conducted approximately 10 years apart. Our approach allows

Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

A Growth‐Coupled Evolutionary Strategy Enhances Heme Biosynthesis in Saccharomyces cerevisiae
Graphical Abstract and Lay Summary Introducing a plasmid with a heme‐responsive promoter connected to a growth‐promoting gene into Saccharomyces cerevisiae created a positive feedback loop between intracellular heme levels and cell growth. After 100 h of adaptive evolution, the plasmid was removed, resulting in a mutant strain that exhibited an ...
