Esta investigación indaga en dos textos clave de la ensayística franco-antillana del siglo XX que comparten una función formativa y un objetivo común de concientización racial y social. Luego de una reflexión sobre los conceptos de cultura y colonialismo,... see more

Text analysis is a useful tool to determine what a company and its customers want in order to improve processes and methodologies of analysis. Searches in databases may have a time series component that determines the importance and sequences of multivari... see more

Hankel matrices are related to a wide range of disparate determinant computations and algorithms and some very attractive computational properties are allocated to them. Also, the Hankel determinants are crucial factors in the research of singularities an... see more

El uso de la correlación producto-momento de Pearson es frecuente en la mayoría de estudios en análisis factorial en psicología, mas es conocido que este estadístico solo es aplicable cuando las variables que se relacionan están al menos en escala de inte... see more

Let M be a (2 × n) non-generic matrix of linear forms in a polynomial ring. For large classes of such matrices, we compute the cohomological dimension (cd) and the arithmetical rank (ara) of the ideal I_2(M) generated by the 2-minors of M. Over an algebra... see more

In this paper we describe the pattern of creation and destruction of Chilean firms between 1999 and 2006. In addition, we construct transition matrices among different firm sizes based on tax information. It has to be noted that the available data for thi... see more
