The Sources of Labor Productivity Growth in Norway, South Korea and Iran: A Structural Decomposition Analysis
Abstract In this paper,using a structural decomposition analysis (SDA) and the latest available input-output tables we investigate the sources of labor productivity growth in Norway, South Korea and Iran. Then, the contribution of each source in the growth of labor productivity is discussed. The results show that among six factors, value added coefficient is the most influencing factoracross al...
متن کاملPrecambrian sponges with cellular structures
Sponge remains have been identified in the Early Vendian Doushantuo phosphate deposit in central Guizhou (South China), which has an age of approximately 580 million years ago. Their skeletons consist of siliceous, monaxonal spicules. All are referred to as the Porifera, class Demospongiae. Preserved soft tissues include the epidermis, porocytes, amoebocytes, sclerocytes, and spongocoel. Among ...
متن کاملPrecambrian Quartzo - Feldspathic Gneiss from the Herman
Precambrian quartzo-feldspathic gneiss was encountered at an elevation of —3616 feet in the Herman 1A well drilled in southeastern Erie County, Ohio, by the Amerada Petroleum Corporation. The five samples of this gneiss that were studied exhibit varying degrees of gneissose foliation. In order of decreasing abundance, microcline, plagioclase, quartz, and biotite together account for an average ...
متن کاملMeiofauna and macrofauna community structure in relation with environmental factors at South of Caspian Sea
Biodiversity and distribution of benthic Meiobenthos in the sediments of the Southern Caspian Sea) Mazandaran) was studied in order to introduce and determine their relationship with the environmental factors. From 12 stations (ranging in depths 5, 10, 20 and 50 meters), sediment samples were gathered in four seasons (2012). Environmental factors of water near the bottom including temperature, ...
متن کاملGeochemistry of carbonaceous impactites from the Gardnos impact structure, Norway
The Gardnos impact structure in southern Norway is one of only two known impact structures (among 175) whose impactites contain significant amounts (typically 0.2–1.0 wt.%) of carbon, or 5 to 10 times the amount present in the target rocks; Sudbury, Canada is the other. This study extends a previous investigation of the geochemistry and petrology of Gardnos impactites (French et al., 1997) with...
