  1. By: Manuel, Eduardo
    Abstract: This paper has as objective to refer the theme “e-Entrepreneurship” having as reference companies of the United States that operate only on internet. We concluded that by fact we are on knowledge era, they and those that it wants to be e-entrepreneur need to work a lot, because, online business will be always exigent when these companies are in different virtual places and where is having different customers, suppliers and rivals companies.

  2. By: F. GAILLY; G. POELS
    Abstract: It is widely recognized that ontologies can be used to support the semantic integration and interoperability of heterogeneous information systems. Resource Event Agent (REA) is a well-known business ontology that was proposed for ontology-driven enterprise system development. However, the current specification is neither sufficiently explicit nor formal, and thus difficult to operationalize for use in ontology-driven business information systems. In this paper REA is redesigned and formalized following a methodology based on the reengineering extension of the METHONTOLOGY framework for ontology development. The redesign is focused on developing a UML representation of REA that improves upon existing representations and that can easily be transformed into a formal representation. The formal representation of REA is developed in OWL. The paper discusses the choices made in redesigning REA and in transforming REA’s UML representation into a OWL representation.

    Abstract: Does the Internet provide a failsafe against media consolidation in the wake of an easing of media ownership rules? This paper posits a model of news outlet selection on the Internet in which consumers experience cognitive costs that increase with the number of options faced. Consistent with psychological evidence, these costs may be reduced by constraining one’s choice set to “safe bets” familiar from offline (e.g., It is shown that, as the number of outlets grows, dispersion of consumer visitation across outlets inevitably declines. Consequently, independent Internet outlets may fail to mitigate lost outlet independence on other media.

    Abstract: A firm sets up a network of information generating alliances to reduce technological uncertainty. This alliance group creates both advantages associated with similarity of existing partners and limitations due to restricted choice of new partners. Our model analyses the conditions (technological uncertainty, information overlap, alliance search costs, and the number of previous alliances) under which a firm opts for an embedded tie within an existing network or an unembedded tie with a new partner.
