Using a sample of 21 OECD-countries we measure productivity in top-edge economic research by using data envelopment analysis (DEA). DEA is a tool for evaluating relative efficiency and is widely used when there are multiple inputs and outputs and one lacks a specific functional form of a production function. The publications in 10 economics journals with the highest average impact factor over t...

BACKGROUND Various studies have shown that the population densities of a number of forest vertebrates, such as orangutans, are higher on Sumatra than Borneo, and that several species exhibit smaller body sizes on Borneo than Sumatra and mainland Southeast Asia. It has been suggested that differences in forest fruit productivity between the islands can explain these patterns. Here we present a l...

In every decade since the 1970’s, computer scientists have re-examined dataflow-based execution models, hoping the programming productivity benefits these models promise can be realized on practical hardware platforms to implement useful applications. Based on the recent Swift/T implementation of “implicitly parallel functional dataflow” (IPFD) for extremescale systems, we believe that the data...

The evidence that earnings rise with firm size and that human capital affects earnings based on labour market data are two of the most robust empirical findings in economics. In contrast the evidence for scale economies in firm data is very weak. The limited direct evidence of human capital on firm productivity suggests that human capital is indeed productive and that the magnitudes are consist...

This study describes the management and products of the Gasconne cattle in two neighbouring countries (Spainand France), as a model study in trans-border breeds, analysing if they are significantly different depending on the place where they are located. Fifty-seven Gasconne breeders were interviewed (32 inSpainand 25 inFrance). The survey examined several aspects of the productive farming syst...

Ammonia can be an essential energy vector for storing excess renewable during the year and release this when demand is high. This storage provides part in sector moments there not enough wind sun to cover demand. Although Haber-Bosch a very mature process synthesize hydrogen nitrogen ammonia, it flexible match erratic nature of renewables. mismatch creates need large intermediate buffer tanks. ...
