Traditional studies in two-stage data envelopment analysis (DEA) assumed that the outputs of the first stage completely input into the second stage. But we think that assumption is not realistic becauses of efficiency loss. This paper modifies the traditional relational two-stage DEA with Variable Returns to Scale (VRS) by abandon this assumption. By introduction of efficiency loss to measure t...

Contradictory results on the evolution of lenticular galaxies (S0s) at intermediate redshift have been recently published. A careful analysis of the used methodology shows that in order to gain insights on the evolution of the morphological types it is necessary: (1) to use quantitative morphological types, (2) to propagate morphological errors in the quantity used to measure the evolution of t...

The median values for hsCRP are 2.5 mg/l (American women) and 1.5 mg/l (American men) [2]. Typical recommendations are to measure hsCRP in ‘‘intermediate risk’’ patients to help classify them into either a higher or lower risk category [3,4]. Intermediate risk is usually, and arbitrarily, described as either a 10%–20% [3,4] or 5%–20% [5,6] 10year risk of developing coronary heart disease (CHD)....

Recent ideal magnetohydrodynamic (MHD) theory predicts that a perturbation evolving from a linear ballooning instability will continue to grow exponentially in the intermediate nonlinear phase at the same linear growth rate. This prediction is confirmed in ideal MHD simulations. When the Lagrangian compression, a measure of the ballooning nonlinearity, becomes of the order of unity, the interme...

We present some results about the structure of c.e. and ∆2 LR-degrees. First we give a technique for lower cone avoidance in the c.e. and ∆2 LR-degrees, and combine this with upper cone avoidance via Sacks restraints to construct a c.e. LR-degree which is incomparable with a given intermediate ∆2 LR-degree. Next we combine measure-guessing with an LR-incompleteness strategy to construct an inco...

This study has examined the effect of semantic mapping on learning vocabulary across genders. The researchers selected 120 intermediate students after the administration of a standard proficiency test. A vocabulary test was also used to measure the students’ vocabulary knowledge. The experimental group received semantic mapping in the pre-reading stage, butthe control group did not receive this...

This study aims at investigating the effects of cooperative language learning on learning active and passive structures among Iranian EFL students. The participants of the study were 60 high school students that were selected from third grade of Barikbin high school in Qazvin. All of the participants were male. Their level of proficiency was intermediate. Then the participants were divided into...
