Mapping Digital Media: Spain

The Mapping Digital Media project examines the global opportunities and risks created by the transition from traditional to digital media. Covering 60 countries, the project examines how these changes affect the core democratic service that any media system should provide: news about political, economic, and social affairs.Since 2005, Spain has designed and implemented aggressive digitization policies that secured the switchoff of analog television in 2010, and developed the digital terrestrial television (DTT) market to saturation point. As a result, cable and satellite subscription services have experienced some decline since 2008. The rapid rise of free-to-air (FTA) digital television has not, however, been replicated in radio, where take-up of the assigned digital audio broadcasting (DAB) standard has been marginal, with little promise of imminent significant growth. This is attributed to a policy focus on digital television, the absence of a digital radio publicity campaign and a switch-off deadline, and the cost of upgrading to digital radio faced by consumers and broadcasters alike.The roll-out of broadband infrastructure has been successful, accounting for 99 percent of all fixed-line connections in 2010. But the consumers' cost of connection remains one of the highest in the European Union (EU), and an enduring digital divide is reflected in the fact that fixed-line internet connections reached only 22 percent of households in 2010.The report also calls for the setting up of an independent regulatory authority on audiovisual matters; the effective implementation of self-regulatory codes concerning media and children; a comprehensive policy program involving concerted action by state institutions, universities, and journalism associations/unions to tackle problems of journalists' pay and conditions; the effective implementation of ethical codes and principles to challenge the abusive dominance of opinion and ideological polarization in the media; the setting up by the Government of a radiocommunications agency to handle radio spectrum policy;the delegation of DTT licensing to this radiocommunications agency; improved publicity for public tenders through the approval of a law on transparency and citizens' access to public information; the promotion of media literacy in school curricula; and finally, the protection of RTVE's political and financing independence to ensure the provision of non-partisan and good-quality journalism to Spanish society

ENOBIO - First Tests of a Dry Electrophysiology Electrode Using Carbon Nanotubes

We describe the development and first tests of ENOBIO, a dry electrode sensor concept for biopotential applications. In the proposed electrodes the tip of the electrode is covered with a forest of multi-walled Carbon Nanotubes (CNTs) that can be coated with Ag/AgCl to provide ionic–electronic transduction. The CNT brushlike structure is to penetrate the outer layers of the skin improving electrical contact as well as increase the contact surface area. In this paper we report the results of the first tests of this concept—immersion on saline solution and pig skin signal detection. These indicate performance on a par with state of the art researchoriented wet electrodes.</p

Communication Policies and the Protection of Pluralism in the European Union and the United States

This article describes and analyses the regulatory frameworks and the current pluralism protection policies in the United States and several countries of the European Union (Germany, France, the United Kingdom, the Netherlands, Italy and Spain). The data obtained allowed a qualitative assessment to be carried out, through a comparative analysis, in order to identify certain similarities and some significant differences. Thus, it was found that pluralism protection is a common denominator in the communication policies of these countries. However, regulatory and legislative differences depend on social, geographical and media contexts, and time variations in the application of policies depend on audiovisual media market liberalisation processes

Effect of nonstationarities on detrended fluctuation analysis

Detrended fluctuation analysis (DFA) is a scaling analysis method used to quantify long-range power-law correlations in signals. Many physical and biological signals are ``noisy'', heterogeneous and exhibit different types of nonstationarities, which can affect the correlation properties of these signals. We systematically study the effects of three types of nonstationarities often encountered in real data. Specifically, we consider nonstationary sequences formed in three ways: (i) stitching together segments of data obtained from discontinuous experimental recordings, or removing some noisy and unreliable parts from continuous recordings and stitching together the remaining parts -- a ``cutting'' procedure commonly used in preparing data prior to signal analysis; (ii) adding to a signal with known correlations a tunable concentration of random outliers or spikes with different amplitude, and (iii) generating a signal comprised of segments with different properties -- e.g. different standard deviations or different correlation exponents. We compare the difference between the scaling results obtained for stationary correlated signals and correlated signals with these three types of nonstationarities.Comment: 17 pages, 10 figures, corrected some typos, added one referenc

Effect of Trends on Detrended Fluctuation Analysis

Detrended fluctuation analysis (DFA) is a scaling analysis method used to estimate long-range power-law correlation exponents in noisy signals. Many noisy signals in real systems display trends, so that the scaling results obtained from the DFA method become difficult to analyze. We systematically study the effects of three types of trends -- linear, periodic, and power-law trends, and offer examples where these trends are likely to occur in real data. We compare the difference between the scaling results for artificially generated correlated noise and correlated noise with a trend, and study how trends lead to the appearance of crossovers in the scaling behavior. We find that crossovers result from the competition between the scaling of the noise and the ``apparent'' scaling of the trend. We study how the characteristics of these crossovers depend on (i) the slope of the linear trend; (ii) the amplitude and period of the periodic trend; (iii) the amplitude and power of the power-law trend and (iv) the length as well as the correlation properties of the noise. Surprisingly, we find that the crossovers in the scaling of noisy signals with trends also follow scaling laws -- i.e. long-range power-law dependence of the position of the crossover on the parameters of the trends. We show that the DFA result of noise with a trend can be exactly determined by the superposition of the separate results of the DFA on the noise and on the trend, assuming that the noise and the trend are not correlated. If this superposition rule is not followed, this is an indication that the noise and the superimposed trend are not independent, so that removing the trend could lead to changes in the correlation properties of the noise.Comment: 20 pages, 16 figure

Prognostic value of cortically induced motor evoked activity by TMS in chronic stroke: caveats from a very revealing single clinical case

Background: We report the case of a chronic stroke patient (62 months after injury) showing total absence of motor activity evoked by transcranial magnetic stimulation (TMS) of spared regions of the left motor cortex, but near-to-complete recovery of motor abilities in the affected hand. Case presentation: Multimodal investigations included detailed TMS based motor mapping, motor evoked potentials (MEP), and Cortical Silent period (CSP) as well as functional magnetic resonance imaging (fMRI) of motor activity, MRI based lesion analysis and Diffusion Tensor Imaging (DTI) Tractography of corticospinal tract (CST). Anatomical analysis revealed a left hemisphere subinsular lesion interrupting the descending left CST at the level of the internal capsule. The absence of MEPs after intense TMS pulses to the ipsilesional M1, and the reversible suppression of ongoing electromyographic (EMG) activity (indexed by CSP) demonstrate a weak modulation of subcortical systems by the ipsilesional left frontal cortex, but an inability to induce efficient descending volleys from those cortical locations to right hand and forearm muscles. Functional MRI recordings under grasping and finger tapping patterns involving the affected hand showed slight signs of subcortical recruitment, as compared to the unaffected hand and hemisphere, as well as the expected cortical activations. Conclusions: The potential sources of motor voluntary activity for the affected hand in absence of MEPs are discussed. We conclude that multimodal analysis may contribute to a more accurate prognosis of stroke patients
