this paper proposes an alternative approach for efficiency analysis when a set of dmus uses interval scale variables in the productive process. to test the influence of these variables, we present a general approach of deriving dea models to deal with the variables. we investigate a number of performance measures with unrestricted-in-sign interval and/or interval scale variables.

Aceptado: 05-10-2014 Rural women's discrimination and the lack of effective implementation of the legislation on gender equality is a phenomenon found around the world. Women have been traditionally the responsible of family care and feeding, thus they have developed productive tasks that allow combining productive and reproductive activities in the farm.

It is well established that extensive reading promotes the incidental learning of L1 and L2 receptive vocabulary; however, little is known about its effectiveness on productive gains in vocabulary knowledge. This paper investigates the extent to which extensive reading combined with writing tasks promotes productive vocabulary growth of Japanese university students. To examine changes in vocabu...

This longitudinal ERP study investigated changes in children's ability to map novel words to novel objects during the dynamic period of vocabulary growth between 20 and 24 months. During this four-month period the children on average tripled their productive vocabulary, an increase which was coupled with changes in the N400 effect to pseudoword-referent associations. Moreover, productive vocabu...

This paper proposes a new resource allocation model which is based on data envelopment analysis (DEA) and concerns systems with several homogeneous units operating under supervision of a central unit. The previous studies in DEA literature deal with reallocating/allocating organizational resource to improve performance or maximize the total amount of outputs produced by individual units. In tho...
