Elogio del papel. Contra el colonialismo digital
La irrupción de las nuevas tecnologías en el cambio de siglo ha comportado una serie de efectos, en gran parte conocidos por todos, que afectan a diversos ámbitos. Así, no sólo se han redefinido industrias (como las culturales) y oficios (como la profesión periodística), sino que se ha llegado al punto de plantear la necesidad de incorporar las herramientas tecnológicas digitales en el sector educativo y en los procesos de participación política. La digitalización es socialmente percibida como un aspecto positivo per se, donde las crisis de estas industrias y sectores no serían más que la antesala de un cambio de paradigma que acabará por ofrecer más libertad de acción a los ciudadanos.

Advances in functional regression and classification models
Functional data analysis (FDA) has become a very active field of research in the last few years because it appears naturally in most scientific fields: energy (electricity price curves), environment (curves of pollutant levels), chemometrics (spectrometric data), etc. This thesis is a compendium of the following publications: 1) "Statistical computing in functional data analysis: the R package fda.usc" published in the J STAT SOFTW, the core advances of this paper was to propose a common framework for FDA in R. 2) "Predicting seasonal influenza transmission using functional regression models with temporal dependence" published in PLoS ONE proposes an extension of GLS model to functional case. 3) "The DD--classifier in the functional setting" published in TEST extends the DD-classifier using information derived of the functional depth. 4) "Determining optimum wavelengths for leaf water content estimation from reflectance: A distance correlation approach" published in CHEMOMETR INTELL LAB SYST studies the utility of distance correlation as a method to select impact points in functional regression. 5) "Variable selection in Functional Additive Regression Models", in Comput Stat proposes a variable selection algorithm in the case of mixed predictors (scalar, functional, etc.)
The DD-classifier in the functional setting
The Maximum Depth was the first attempt to use data depths instead of
multivariate raw data to construct a classification rule. Recently, the
DD-classifier has solved several serious limitations of the Maximum Depth
classifier but some issues still remain. This paper is devoted to extending the
DD-classifier in the following ways: first, to surpass the limitation of the
DD-classifier when more than two groups are involved. Second to apply regular
classification methods (like NN, linear or quadratic classifiers, recursive
partitioning,...) to DD-plots to obtain useful insights through the diagnostics
of these methods. And third, to integrate different sources of information
(data depths or multivariate functional data) in a unified way in the
classification procedure. Besides, as the DD-classifier trick is especially
useful in the functional framework, an enhanced revision of several functional
data depths is done in the paper. A simulation study and applications to some
classical real datasets are also provided showing the power of the new
proposal.Comment: 29 pages, 6 figures, 6 tables, Supplemental R Code and Dat
E-Government Strategies in Spanish Local Governments
Interest in the use of new technologies as an instrument for the modernisation of public management is something common in public administrations. Local governments have recently invested considerable human and material resources to try to deliver services in a more efficient way. Although the progress made in the implementation of information and communication technology (ICT) has been significant, an analysis of all local government shows that its impact on the reform policies has been unequal, and that the real objectives of these processes of modernisation have not always been the same. Most governments have chosen a strategy that reproduces the way that the traditional administration works; whereas only a few have tried to make use of the potential that ICT offers to provide more transparency, new online services and to make administrations more receptive to citizens’ needs. The first section of this article gives global data about the development of ICT in Spanish municipalities. Next, the websites of Spanish cities are analysed to identify the factors that enhance e-government and its implementation in the benefit of transparency, interaction with citizens and accountabilit
