The present study evaluated the learning objectives represented in the recent Iranian nation-wide ELT textbooks, i.e. Prospect and Vision series, and compared them to those in the internationally-published textbook of Four Corners. To this end, Bloom’s revised taxonomy of learning objectives was utilized as the analytical framework to scrutinize the tasks and exercises of the textbooks using a ...

This paper studies the effect of the space (distance) between lotteries' outcomes on risk-taking behavior and the shape of estimated utility and probability weighting functions. Previously investigated experimental data shows a significant space effect in the gain domain. As compared to low spaced lotteries, high spaced lotteries are associated with higher risk aversion for high probabilities o...

We solve the N-body Calogero problem, i.e. N particles in 1 dimension subject to a two-body interaction of the form 1 2 ∑ i,j[(xi − xj) + g/(xi − xj)], by constructing annihilation and creation operators of the form ai = 1 √ 2 (xi±ip̂i), where p̂i is a modified momentum operator obeying Heisenberg-type commutation relations with xi, involving explicitly permutation operators. On the other hand, D...

The overall objective of cell transplantation is to repopulate postinfarction scar with contractile cells, thus improving systolic function, and to prevent or to regress the remodeling process. Direct implantation of isolated myoblasts, cardiomyocytes, and bone-marrow-derived cells has shown prospect for improved cardiac performance in several animal models and patients suffering from heart fai...

Objective: To align pharmacologic classes in ATC and MeSH with lexical and instance-based techniques. Methods: Lexical alignment: we map the names of ATC classes to MeSH through the UMLS, leveraging normalization and additional synonymy. Instance-based alignment: we associate ATC and MeSH classes through the drugs they share, using the Jaccard coefficient to measure class-class similarity. We u...

This paper discusses the informational requirements of layered manufacturing (LM). The most common industrial use of LM today is for rapid prototyping, but we take a wider view of it as a flexible fabrication technology. Its use in building functional metallic parts under computer control has already been demonstrated in the research context. Commercial LM machines for building production parts...

Metamaterials offer the prospect of new science and applications. They have been designed by shaping or changing the material of the individual meta-molecules to achieve properties not naturally attainable. Composite meta-molecules incorporating a magnetic component offer new opportunities. In this work we report on the interaction between a non-magnetic split ring resonator (SRR) and a thin fi...

For data warehouse and OLAP (On-Line Analytical Processing) systems various preparation tasks are necessary to qualify and improve the effectiveness of their usage. In order to put into operation such a task the creation of statistical sound sample data is indispensable. Applying statistical models for the generation of sample data promises a high-quality prospect which allows the production of...

One of the most common early forecasts for commerce in the information age was the removal of wholesalers, distributors, and other intermediaries in a firm’s value chain. This "disintermediation” offered the prospect of greater efficiency in supply and marketing channels. More recent evidence suggests that such forecasts were shortsighted, and today new “cybermediaries” have lodged themselves i...

Regenerative medicine and emerging biotechnologies stand to revolutionize the practice of medicine. Advancements in stem cell biology, including embryonic and postnatal somatic stem cells, have made the prospect of tissue regeneration a potential clinical reality. Short of reproductive cloning, these same technologies, properly used, could allow for the creation of replacement tissue for the de...
