Using history to help refine international business theory: ownership advantages and the eclectic paradigm.

In John Dunning’s eclectic paradigm firms need to have ownership, location, and internalisation advantages in order to cross borders and engage in foreign direct investment. By drawing on historical evidence on the evolution of a group of leading marketing-based multinationals in consumer goods, this paper claims that, despite its richness, the eclectic paradigm, and in particular the concept of ‘ownership advantages’, needs to be revised and extended, to take into account different levels of institutional analysis. For the eclectic paradigm to give a rounded view of the internationalising firm it needs to acknowledge the critical importance of firm-specific ownership advantages such as the role of the entrepreneur

Rheological behavior of thermoreversible k-carrageenan/nanosilica gels

The rheological behavior of silica/κ-carrageenan nanocomposites has been investigated as a function of silica particle size and load. The addition of silica nanoparticles was observed to invariably impair the gelation process, as viewed by the reduction of gel strength and decrease of gelation and melting temperatures. This weakening effect is seen, for the lowest particle size, to become slightly more marked as silica concentration (or load) is increased and at the lowest load as particle size is increased. These results suggest that, under these conditions, the particles act as physical barriers to polysaccharide chain aggregation and, hence, gelation. However, for larger particle sizes and higher loads, gel strength does not weaken with size or concentration but, rather, becomes relatively stronger for intermediate particles sizes, or remains unchanged for the largest particles, as a function of load. This indicates that larger particles in higher number do not seem to increasingly disrupt the gel, as expected, but rather promote the formation of stable gel network of intermediate strength. The possibility of this being caused by the larger negative surface charge found for the larger particles is discussed. This may impede further approximation of neighboring particles thus leaving enough inter-particle space for gel formation, taking advantage of a high local polysaccharide concentration due to the higher total space occupied by large particles at higher loads.FCT - PTDC/QUI/67712/2006FEDE

Formalism of operators for Laguerre-Gauss modes

In this work apply the algebra of operators of quantum mechanics in the Helmholtz wave equation in cylindrical coordinates in paraxial approximation to describe the raising and lowering operators for the Laguerre-Gauss modes

Banco de dados da coleta de germoplasma de feijão no Brasil para a realização de um SIG.

O objetivo deste trabalho é identificar os locais de coleta de feijão em função do mapeamento das áreas em questão. Este processo está sendo realizado através da interface do Sistema de Informações Geográficas (SIG) e do Sistema Gerenciador de Banco de Dados Relacional (SGBR) do software SPRING, para fins de armazenar e recuperar dados geográficos assim como os atributos não-espaciais
