Workers in industries with growing export exposure have lasting earning gains: 1. We analyze at which margin export shocks are capitalized into earnings gains: on-the-job with the original employer or in a different firm but within the original industry? 2. Detect meaningful heterogeneity in the export adjustment mechanisms: Are gains from exports reaped by all workers or do better skilled work...

Composite likelihood may be useful for approximating likelihood based inference when the full likelihood is too complex to deal with. Stemming from a misspecified model, inference based on composite likelihood requires suitable corrections. Here we focus on the composite likelihood ratio statistic for a multidimensional parameter of interest, and we propose a parameterization invariant adjustme...

Land use of sewage sludge is the primary disposal method in Shanxi, accounting for 42.66% of all. To determine the ecological risk of heavy metals in sewage sludge, contents of seven heavy metals in sewage sludge from 9 municipal waste water treatment plants (WWTPs) that had the highest application for land use were determined. The order of the measured concentrations was: Zn > Cr > Cu > Ni > P...

We propose a lighting system which adjusts lighting colors. The lighting system adjusting colors is a system that provides required illuminance and lighting color at an appropriate location. This system consists of many intelligent lighting with RGB fluorescent lamps, many chroma sensors and an electric power meter. These equipments are connected to a network. The chroma sensor can measure the ...
