Efficiency Potential and Efficiency Variation in Norwegian Lower Secondary Schools

Competition and the Efficiency of Secondary Schools in England

Efficiency of Secondary Schools in Portugal: a Stochastic Frontier Analysis*

The scores in the national examinations taken by students at the end of their secondary courses have received much public attention in recent years, partly justified by the importance they have among the criteria for admission to higher education. These scores also have been used to evaluate the performance of Portuguese schools offering secondary courses. The aim of this paper is to analyse su...

Genetic variation in efficiency to deposit fat and lean meat in Norwegian Landrace and Duroc pigs.

Feed costs amount to approximately 70% of the total costs in pork production, and feed efficiency is, therefore, an important trait for improving pork production efficiency. Production efficiency is generally improved by selection for high lean growth rate, reduced backfat, and low feed intake. These traits have given an effective slaughter pig but may cause problems in piglet production due to...

Secondary Fractures and Their Potential Impacts on Hydraulic Fractures Efficiency

Outcrop studies have revealed the presence of abundant cemented fractures in many low permeable formations. Recovered cores have also revealed the opening of some of these smaller size fractures on the wall surface of main hydraulic fractures. Furthermore, earlyproduction well-testing analysis in some of these cases provide estimates for hydraulically induced fracture surface areas which are mu...
