"This is a story about the closure of a major US research instrument due to posturing politicians, fake facts, scientists untrained in public speaking, and a Federal bureaucracy unable to resist political pressure. The story foreshadows today's episodes of science denial, and offers insights for how to cope with it"--

From 2002-2004, the German government passed several laws that curtailed the generosity of the unemployment compensation system. One of the most ambitious changes was a considerable reduction in unemployment benefit entitlement lengths for older unemployed, which was effective during 2006 and 2007. We apply a difference-in-differences approach to show that the highly disputed reform induced a considerable decline in unemployment incidence among older workers. It thus sealed an important leak in the unemployment insurance system. Furthermore, we find a strong anticipation effect; unemployment entries of elderly workers peaked during the months preceding the reform.

Leaker critiques the role that the defence of free speech has played in legitimising the scapegoating of oppressed minorities while deflecting attention from the egregious operations of power that have led to ever greater inequality, injustice and capitalist destruction.

AbstractDespite decades of research, the pitting of copper pipes is poorly understood. This article summarizes the key research findings from 1990 to the present and identifies research gaps. Several lines of evidence suggest that, for soft waters, additional alkalinity or maintaining a pH <8.5 may reduce copper pitting. Phosphate corrosion inhibitors, used to prevent lead corrosion, may also moderate copper pitting in low‐alkalinity waters. However, such inhibitors could also exacerbate pitting due to insufficient coverage or could increase biological growth. Biological processes are likely involved in pitting corrosion, and practices to reduce biological growth may be beneficial. The research gaps identified include a need for better benchmarking, the effects of chemical transients (e.g., chlorine burns) and of hydraulic transients (e.g., water hammer), and changing the residual disinfectant from chlorine to chloramine.Article Impact StatementApproximately 750,000 pinhole leaks are estimated to occur in the United States each year, but we do not really know why.
