In the modern age, Occidentalism as a process of signifying practices based upon the notion of “the West” has played a hegemonic role in the configuration of collective identity and alterity. The imaginary geography of “the West” has been one…

This paper uses dynamic general equilibrium and computational methods, inspired by the multi-sector growth model structure in Stephen Turnovsky's work, to develop a theory that unifies two of the traditional explanations of structural change: sector-biased technical change and non-homothetic preferences.…

This article examines the role of lexical morphology in pedagogical grammars of Spanish as a way
to increase knowledge of vocabulary. We review the ways in which derivation and compounding are
introduced in Spanish textbooks and which present different types…

The Semantic Web attempts to reach a state in the future where everything on the Web will no longer be only machine-readable, but also machine-understandable. An ontology is an explicit specification of a conceptualization. A conceptualization is an abstract, simplified…

Much effort has been dedicated to provide a general model of agents working in complex environments. This research focuses on the high level cognition used in determining the behavior of the agent.
The language of the Situation Calculus represents a…

The field of machine learning (ML) is concerned with the question of how to construct algorithms that automatically improve with experience. In recent years many successful ML applications have been developed, such as datamining programs, information-filtering systems, etc. Although ML…
