With the emergence of information and communication technologies, a large amount of data has turned available for the organizations, which creates expectations on their value and content for management purposes. However, the exploratory analysis of available organizational data based on emerging Big Data technologies are still developing in terms of operative tools for solid and interpretable data description. In this work, we addressed the exploratory analysis of organization databases at early stages where little quantitative information is available about their efficiency. Categorical and metric single-variable tests are proposed and formalized in order to provide a mass criterion to identify regions in forms with clusters of significant variables. Bootstrap resampling techniques are used to provide nonparametric criteria in order to establish easy-to-use statistical tests, so that single-variable tests are represented each on a visual and quantitative statistical plot, whereas all the variables in a given form are jointly visualized in the so-called chromosome plots. More detailed profile plots offer deep comparison knowledge for categorical variables across the organization physical and functional structures, while histogram plots for numerical variables incorporate the statistical significance of the variables under study for preselected Pareto groups. Performance grouping is addressed by identifying two or three groups according to some representative empirical distribution of some convenient grouping feature. The method is applied to perform a Big-Data exploratory analysis on the follow-up forms of Spanish Red Cross, based on the number of interventions and on a by-record basis. Results showed that a simple one-variable blind-knowledge exploratory Big-Data analysis, as the one developed in this paper, offers unbiased comparative graphical and numerical information that characterize organizational dynamics in terms of applied resources, available capacities

La introducción del arte en el sistema-red, ha creado cambios significativos en el paradigma artístico, tanto dentro del espacio cibernético, como fuera de el mismo. Igualmente se han producido cambios en la idea del artista, del objeto artístico y d e la Institución. Se han contemplado nuevas formas de crear arte, ya que cualquier forma expresiva conocida hasta la fecha, se manifiesta en un primer instante en forma de mensaje, y estará sujeta al flujo rizomático propio del sistema-red.

Net.art until now, has been understood as a visual proposal by an artist, who initially fled to the concerns raised by the art institution, primarily because it is an ubiquitous and virtual product. This article, based on a PhD presented at the Universidad Complutense de Madrid and proposed as a preview of a book to be pushed by Trea, reviews how the concept of net art has changed, according to its different phases., El net.art hasta ahora había sido entendido como una propuesta visual de un artista, que un inicio escapaba a las consideraciones planteadas por la Institución, principalmente por ser un producto ubicuo y virtual. Aquí se plantea cómo se ha modificado el concepto de net.art, atendiendo a sus diferentes fases. Este artículo está basado en una tesis doctoral defendida en la Universidad Complutense de Madrid, y es anticipo de un libro que va a ser publicado por editorial Trea.
