We determine optimal discretionary monetary policy in a New-Keynesian model when nominal interest rates are bounded below by zero. Nominal interest rates should be lowered faster in response to adverse shocks than in the case without bound. Such ‘preemptive easing’ is optimal because expectations of a possibly binding bound in the future amplify the e ects of adverse shocks. Calibrating the mod...

The link between unemployment and pension accumulations is conceptually straightforward; periods of unemployment lead to lower pension contributions, and thus to lower accumulations. However, impacts on accumulation may differ as a result of the timing and frequency of unemployment spells. We hypothesize that unemployment is more likely during periods in which the equities market experiences gr...

We aimed to examine the effect of micronutrient losses through sweat on blood pressure (BP) among heat-exposed steelworkers. A total of 224 heat-exposed male steelworkers from an ironworks facility were evaluated in July 2012. We measured the Wet Bulb Globe Temperature Index to evaluate the level of heat stress in the workplace. We collected sweat from the workers during an eight-hour work, and...

Abstract The volume of water losses depends largely on the approach to active leakage control networks. Losses comprise physical (leakages transmission and/or distribution networks, at utility’s storage tanks, and service connections), commercial (unauthorised consumption metering inaccuracies data handling errors) unbilled authorised (unbilled metered unmetered consumption). Reduction real may...

selfish director, however, might restrict himself to poaching the best staff members from the university without giving anything back. Writing for the daily paper Frankfurter Allgemeine Zeitung (FAZ), the nine university professors, led by biochemist Günter Blobel from Rockefeller University, have outlined what they call the “unsolved MaxPlanck problem” of German research, namely the artificial...

Slow light devices such as photonic crystal waveguides (PhCW) and coupled resonator optical waveguides (CROW) have much promise for optical signal processing applications and a number of successful demonstrations underpinning this promise have already been made. Most of these applications are limited by propagation losses, especially for higher group indices. These losses are caused by technolo...
