AbstractA class of matrices that simultaneously generalizes the M-matrices and the inverse M-matrices is brought forward and its properties are reviewed. It is interesting to see how this class bridges the properties of the matrices it generalizes and provides a new perspective on their classical theory.

This article discusses alternative and complementary proposals to j.C.Maxwell’s laws of classical electromagnetism, based on certain hypotheses, hypothetical examples and calculations, with results that may infer new interpretations about the physical phenomenon conduction current density. These new interpretations bring a new understanding to the dynamics of Gauss’s Law, and, being true, make the Amperre-Maxwell Law totally symmetrical to the faraday-lenz-maxwell law, without any mathematical or physical inconsistency. These understandings inevitably bring implications and points of view complementary to the classical theory of electromagnetism.

El hombre posmoderno es un Narciso en busca de su identidad. La evaporación del Padre ha camiado las dinámicas en relación con el Otro y la capacidad de construir una propia identidad tiene que recurrir a los objetos de consumo. En este estudio se propone un camino que va desde la teoría clásica del Psicoanálisis hasta una nueva perspectiva que entra en el campo del Márketing y del estudio de objeto de consumo. The post-modern man is a Narcissus is seeking his identity. The Evaporation of the Father has changed the dynamics of relationship with the Other and the ability to build one’s own identity has to resort to consumer objects. This study proposes a path that goes from the classical theory of Psychoanalysis to a new perspective that enters the field of Marketing and the study of the object of consumption..

The understanding of the interactions between the small metallic particles and ceramic surfaces has been studied by many catalyst scientists. We had developed Scanning Reflection Electron Microscopy technique to study surface structure of MgO hulk cleaved surface and the interaction with the small particle of metals. Resolutions of 10Å has shown the periodic array of surface atomic steps on MgO. The SREM observation of the interaction between the metallic particles and the surface may provide a new perspective on such processes.

This paper describes the concept of teaching articulation through words which have inherent meaning to a child’s life experience, such as a semantically potent word approach. The approach was used with six children. Comparison of pre/post remediation measures indicated that it has promise as a technique for facilitating increased correct phoneme production.

Abstract. Based on responses from 158 reward managers located at the headquarters or subsidiaries of multinational enterprises, the present study examines the relationship between the centralization of reward management decision making and its perceived effectiveness in multinational enterprises. Our results show that headquarters managers perceive a centralized approach as being more effective, while for subsidiary managers this relationship is moderated by the manager’s role identity. Referring to social identity theory, the present study enriches the standardization versus localization debate through a new perspective focusing on psychological processes, thereby indicating the importance of in-group favoritism in headquarters and the influence of subsidiary managers’ role identities on reward management decision making.
