The effect of unemployment insurance on alcohol use and abuse following job loss.

We investigate whether unemployment insurance (UI) policy affects the drinking behavior of the unemployed. Using NLSY data supplemented with Geocode data, we estimate the effect of benefit replacement rates on changes in individual alcohol consumption following job loss. Identification relies on variation in replacement rates across states and over time.

Comparative disinfection efficiency of pulsed and continuous-wave UV irradiation technologies.

Pulsed UV (PUV) is a novel UV irradiation system that is a non-mercury lamp-based alternative to currently used continuous-wave systems for water disinfection. PUV polychromatic irradiation disinfection efficiency was compared to that from continuous-wave monochromatic low-pressure (LP) and polychromatic medium-pressure (MP) UV systems, using two types of actinometry (ferrioxalate and iodide-iodate) and an absolute spectral emission method for fluence measurement. All three methods were in good agreement.
