Démter y Perséfone: mito y narrativa en la poesía de Michéle Roberts

[ES]Este trabajo estudia la obra poética que dedica la autora feminista y anglo-francesa Michèle Roberts al mito de Deméter y Perséfone. A través de seis poemas presentados correlativamente, Roberts recorre la historia mitológica de dos mujeres simbólicas para reescribir y reinterpretar distintas percepciones del mito que engloba a las heroínas. Pasado y presente se corresponden, así como las valoraciones de la alegoría ficticia y la cultura contemporánea. En los poemas de Roberts, las narrativas en primera y tercera persona se entrelazan para tratar diversos temas como la relación entre madre e hija, el matrimonio, el ataque sexual, la identidad de las protagonistas, el inconsciente, el nacimiento y la muerte.

Normalized Frobenius condition number of the orthogonal projections of the identity

[EN]This paper deals with the orthogonal projection (in the Frobenius sense) AN of the identity matrix I onto the matrix subspace AS (A ? Rn×n, S being an arbitrary subspace of Rn×n). Lower and upper bounds on the normalized Frobenius condition number of matrix AN are given. Furthermore, for every matrix subspace S ? Rn×n, a new index bF (A, S), which generalizes the normalized Frobenius condition number of matrix A, is defined and analyzed...

Gender and identity classification for a naive and evolving system

[EN]This paper does not propose a new technique for face representationorclassification. Insteadtheworkdescribed here investigates the evolution of an automatic system which, based on a currently common framework, and starting from an empty memory, modifies its classifiers according to experience. In the experiments we reproduce up to a certain extent the process of successive meetings. The results achieved, even when the number of different individuals is still reduced compared to off-line classifiers, are promising.
