test method facet is one of the factors which can have an influence on the test takers’ performance. the purpose of the current study was to investigate the effects of two different response types, multiple-choice cloze and multiple-choice test, on the pre-intermediate and intermediate test takers’ reading comprehension performance. to this end, 40 pre-intermediate and intermediate learners par...

In this paper we prove that the plurality rule and the run o procedure are asymptotically strategy proof for any number of alternatives and that the ratio of the number of all manipulable pro les upon the to tal number of pro les in both cases is it the order of O p n Introduction The well known impossibility theorem of Gibbard and Satterthwaite states that every non dictatorial social choice f...

Liquid desiccants such as glycols are used in dehydration process, among which Triethylene Glycol (TEG) is considered as a common choice. The addition of nanoparticles to TEG as the base fluid is one of the prevalent method to improve thermal properties of TEG. In this study, an experimental investigation was performed on thermal conductivity of TEG-based nanofluids with 20 and 40 nm diameter c...

Nonlinear Knapsack Problems (NKP) are the alternative formulation for the multiple-choice knapsack problems. A powerful approach for solving NKP is dynamic programming which may obtain the global op-timal solution even in the case of discrete solution space for these problems. Despite the power of this solu-tion approach, it computationally performs very slowly when the solution space of the pr...

The scientist who is asked to anonymously review a colleague’s article submission and wants to gather background materials from the author’s web site. T...

Fix a prime number l. In this paper we develop the theory of relative pro-l completion of discrete and profinite groups — a natural generalization of the classical notion of pro-l completion — and show that the pro-l completion of the Torelli group does not inject into the relative pro-l completion of the corresponding mapping class group when the genus is at least 2. (See Theorem 1 below.) As ...

Hepatocyte growth factor (HGF) is biosynthesized as a biologically inactive, single-chain form (pro-HGF). Its activation is associated with cleavage at Arg494-Val495 into a two-chain mature form composed of disulfide-linked alpha- and beta-chains. Because serum is a major source of HGF activator (the predominant serine protease responsible for the processing of pro-HGF), serum-free production o...

This paper assesses the e¢ciency of store characteristics in the supermarket industry using a model of store choice estimated with a consumer survey and a dataset of store characteristics. We measure the private gains to ...rms, and external impacts, of a series of counterfactual changes to store characteristics. The existing stores most pro...table to their ...rms are smaller and reduce consum...
