We consider a monopolist who sells a set of products over a time horizon of T periods. The seller initially does not know the parameters of the products’ linear demand curve, but can estimate them based on demand observations. We first assume that the seller knows nothing about the parameters of the demand curve, and then consider the case where the seller knows the expected demand under an inc...
bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...

The April 2013 News article “Secret Ingredients: Who Knows What’s in Your Food?” [Environ Health Perspect 121:A126–A133 (2013] included a simplified version of Figure 1B from Neltner et al. [Navigating the U.S. food additive regulatory program. Compr Rev Food Sci Food Saf 10(6):342–368 (2011)]. In simplifying the figure, EHP introduced errors. We furthermore later determined that Figure 2 from ...

The educated citizen is politically attentive, knowledgeable, and participatory, and the uneducated citizen is not. However, this fact conceals a less favorable effect of education. Educated citizens possess the cognitive skills to reject facts inconsistent wi...
Online communities have become important places for users to share information. In this context, the work described in this article aims to analyze computational methods that could allow us to identify users with the highest expertise levels on a specific knowledge domain in an online community. In this study the authots extracted data from a Java discussion group from an online community Faceb...
In this issue of the Journal, Besaratinia and Pfeifer (1) add to the toxicologic evidence that acrylamide has the ability to induce genetic damage in mammalian cells. Acrylamide or probably glycidamide, its genotoxic metabolite, has a relatively low mutagenic potency and is likely to have a relatively small impact on the overall cancer risk of an individual. However, because rather high concent...
In this paper we take a view from the bottom to RDF(S) reasoning. We discuss some issues and requirements on reasoning towards effectively building Semantic Web Pipes, aggregating and patching RDF data from various distributed sources. Even if we leave out complex description logics reasoning and restrict ourselves to the RDF world, it turns out that some problems, in particular how to deal wit...
