This document describes a general structure for the implementation of virtual tools for remote calculation through Internet. Two virtual tools for mathematical analysis
(Analys) and simulation of dynamic systems (SimWeb), supported by the Matlab c, are described. These virtual tools,…

education of pre-service teachers in teacher training institutions in four different countries: Australia, Canada, Hong Kong, and Singapore. Using the Attitudes Towards Inclusive Education Scale (Wilczenski, 1995) and a series of demographic variables, this study concludes that pre-service teachers' attitudes…

This survey presents within a single model three theories of decentralization of decision-making within organizations based on private information and incentives. Renegotiation, collusion, and limits on communication are three sufficient conditions for decentralization to be optimal., Cet article présente, dans…

We analyze an alternative to the standard rationalizability requirement for observed choices by considering non-deteriorating selections. A selection function is a generalization of a choice function where selected alternatives may depend on a reference (or status quo) alternative in addition…

A very sound knowledge of variations of head and neck veins is important for General practitioners, plastic surgeons, interventional radiologists, internists and maxillofacial surgeons. Anatomic variations have a definite embryological basis and manifest their clinical impact. The Present study was…

We identify conditions under which preferences over sets of consumption opportunities can be reduced to preferences over bundles of \"commodities\". We distinguish ordinal bundles, whose coordinates are defined up to monotone transformations, from cardinal bundles, whose coordinates are defined up…

This paper provides new versions of Harsanyi’s social aggregation theorem that are formulated in terms of prospects rather than lotteries. Strengthening an earlier result, fixed-population ex-ante utilitarianism is characterized in a multi-profile setting with fixed probabilities. In addition, we extend…

This paper proposes a definition of relative uncertainty aversion for decision models under complete uncertainty. It is shown that, for a large class of decision rules characterized by a set of plausible axioms, the new criterion yields a complete ranking…

Uma proposta para a aprendizagem utilizando a pesquisa em sala de aula por um processo de busca de informações para serem analisadas, discutidas, questionadas e posteriormente submetidas a uma reconstrução por meio de elaborações, tendo como resultado a autoria individual…
