Creatividad, atención y rendimiento académico en alumnado de conservatorio profesional

El objetivo de este trabajo fue analizar la relación entre creatividad, atención y su repercusión en los resultados académicos en las enseñanzas profesionales de música. Para ello, se ha seleccionado una muestra de 84 alumnos de entre 12 y 18 años (M = 14.79; DT = 2.29) que cursan Enseñanzas Profesionales en un Conservatorio de Música público y reglado. Se utilizaron como instrumentos de medida el Test de Inteligencia Creativa (CREA; Corbalán et al. 2003) y el Test de Atención (d2; Brickenkamp, 2004). Se hallaron correlaciones positivas y estadísticamente significativas entre (a) atención y creatividad y (b) atención y resultados académicos musicales. En cambio, se hallaron correlaciones negativas y estadísticamente significativas entre creatividad y rendimiento académico musical. Tras los resultados se pueden establecer programas preventivos o potenciadores de la creatividad y la atención, con el fin de fomentar que la totalidad del alumnado de conservatorio alcance su máximo potencial y un alto rendimiento, ya que éstos son el reflejo de un aprendizaje más eficaz.

Calmness modulus of linear semi-infinite programs

Our main goal is to compute or estimate the calmness modulus of the argmin mapping of linear semi-infinite optimization problems under canonical perturbations, i.e., perturbations of the objective function together with continuous perturbations of the right-hand side of the constraint system (with respect to an index ranging in a compact Hausdorff space). Specifically, we provide a lower bound on the calmness modulus for semi-infinite programs with unique optimal solution which turns out to be the exact modulus when the problem is finitely constrained. The relationship between the calmness of the argmin mapping and the same property for the (sub)level set mapping (with respect to the objective function), for semi-infinite programs and without requiring the uniqueness of the nominal solution, is explored, too, providing an upper bound on the calmness modulus of the argmin mapping. When confined to finitely constrained problems, we also provide a computable upper bound as it only relies on the nominal data and parameters, not involving elements in a neighborhood. Illustrative examples are provided.

Enrichment of the Phenotypic and Genotypic Data Warehouse analysis using Question Answering systems to facilitate the decision making process in cereal breeding programs

Currently there are an overwhelming number of scientific publications in Life Sciences, especially in Genetics and Biotechnology. This huge amount of information is structured in corporate Data Warehouses (DW) or in Biological Databases (e.g. UniProt, RCSB Protein Data Bank, CEREALAB or GenBank), whose main drawback is its cost of updating that makes it obsolete easily. However, these Databases are the main tool for enterprises when they want to update their internal information, for example when a plant breeder enterprise needs to enrich its genetic information (internal structured Database) with recently discovered genes related to specific phenotypic traits (external unstructured data) in order to choose the desired parentals for breeding programs. In this paper, we propose to complement the internal information with external data from the Web using Question Answering (QA) techniques. We go a step further by providing a complete framework for integrating unstructured and structured information by combining traditional Databases and DW architectures with QA systems. The great advantage of our framework is that decision makers can compare instantaneously internal data with external data from competitors, thereby allowing taking quick strategic decisions based on richer data.
