"Anastas, o el origen de la Constitución", de Juan Benet. Reflexiones escénicas sobre el poder

Anastas, o el origen de la Constitución, reflexiona en pocas páginas sobre el drama del poder, sus efectos desastrosos para el que lo ostenta y para los gobernados. El análisis de las categorías dramáticas: la fábula, los personajes, el espacio y los tiempos, descubre una construcción basada en la radicalidad de sus oposiciones y en la convergencia semiótica de la disposición en la trama; el enfrentamiento entre los personajes es siempre binario; la disposición de motivos es una tira trágica en la que se repite el mismo cuadro. Los signos no verbales de la escena se suman a esta disposición y todo en el drama contribuye a crear una tensión insoportable.Anastas, or the Origin of the Constitution is a short play that thinks about the drama of the power, and its disastrous effects both on the one that holds it and on the crowd of people that suffer it. The analysis of the dramatic categories of the piece (the fable, the main characters, the space and the times) discovers to us a literary construction based on the radicalism of its confrontations and on the semiotic convergence of the plot disposition: the clash between the characters is always binary; the disposition of the reasons is a tragic strip that repeats itself one vignette after the other. The non-verbal signs of the scene reinforce this disposition, and everything in the drama helps to create an unbearable tension

Voltage and frequency regulation to support synchronous generators operation by grid feeding distributed energy resources

Research on new grid topologies and control configurations to support distributed energy resources is being carried out in order to improve electric service reliability and better power quality to the end consumer. Besides, due to more restrictive environmental policies and economical incentives for the deployment of new renewable energy resources, the energetic scenario seems to be moving towards a more sustainable one. With the increasing proliferation of renewable energies and distributed energy resources, however, the challenges that future grids will have to confront can only escalate. Before dealing with these new challenges, it is first necessary to fully comprehend how a standard grid is regulated and to embrace the fundamentals on grid operation and management from a technical perspective. By understanding how current grids function, the effect of these new actors on the grid namely distributed energy resources can be isolated and addressed either individually as a new phenomenon never encountered before or extrapolated from a well-known challenge of the mains. In this thesis, the operating of the standard grid is depicted together with these forthcoming technologies such as microgrids and distributed energy resources. The synchronous generator together with its regulator and its excitation system prove to be key actors in terms of frequency and voltage regulation thus special emphasis is given to them. Simulations regarding the control of the synchronous generator and its influence on the grid stability are performed to support the many literature that attribute the synchronous generator as the par excellence regulator of the grid. Finally, the interaction between an inverter-based distributed generation and a diesel-based distributed generation is studied to identify its effects on both the dynamic response of the grid and its stability. The realized simulations provide scenarios in which to test the importance of the synchronous generation inasmuch as the regulation of the grid is concerned. In addition, the introduction of an inverter-based distributed generation in the simulations is particularly interesting to present the benefits that the support from distributed generation on the grid can bring about

Adaptations in genres with story: From novel to media. “La regenta. Versión teatral libre de la obra homónima de Leopoldo Alas Clarín”, by Marina Bollaín, with the collaboration of Vanessa Montfort

The paper analyses the problems generated by the adaptation of stories between genres: novel, theatre, cinema and TV, focusing on the only adaptations that have been made of Clarín’s La Regenta, and particularly, on the TV version by M. Bollaín. The adaptation process involves two authors, two texts and two ways of reception. The text belongs to different genres, with verbal and non-verbal languages. The adapted text is the effect of a transduction process, which is achieved thanks to the semantic ambiguity and polyvalence of the literary textEl artículo analiza los problemas que suscitan las adaptaciones de relatos entre géneros: novela, teatro, cine y televisión, concretándolos en las que se han hecho de La Regenta de Clarín y en especial la versión televisiva realizada por M. Bollaín. El proceso de adaptación implica dos autores, dos textos y dos modos de recepción. Los textos pertenecen a géneros diferentes, con lenguajes diferentes (verbal y no verbal). El texto adaptado es efecto de un proceso de transducción, que es posible dada la ambigüedad y polivalencia semántica del texto literari

Why prudence is needed when interpreting articles reporting clinical trial results in mental health

Background: Clinical trial results' reliability is impacted by reporting bias. This is primarily manifested as publication bias and outcome reporting bias. Mental health trials' specific features: Mental health trials are prone to two methodological deficiencies: (1) using small numbers of participants that facilitates false positive findings and exaggerated size effects, and (2) the obligatory use of psychometric scales that require subjective assessments. These two deficiencies contribute to the publication of unreliable results. Considerable reporting bias has been found in safety and efficacy findings in psychotherapy and pharmacotherapy trials. Reporting bias can be carried forward to meta-analyses, a key source for clinical practice guidelines. The final result is the frequent overestimation of treatment effects that could impact patients and clinician-informed decisions. Mechanisms to prevent outcome reporting bias: Prospective registration of trials and publication of results are the two major methods to reduce reporting bias. Prospective trial registration will allow checking whether they are published (so it will help to prevent publication bias) and, if published, whether those outcomes and analyses that were deemed as appropriate before trial commencement are actually published (hence helping to find out selective reporting of outcomes). Unfortunately, the rate of registered trials in mental health interventions is low and, frequently, of poor quality. Conclusion: Clinicians should be prudent when interpreting the results of published trials and some meta-analyses - such as those conducted by scientists working for the sponsor company or those that only include published trials. Prescribers, however, should be confident when prescribing drugs following the summary of product characteristics, since regulatory agencies have access to all clinical trial results

Characterization of ten white matter tracts in a representative sample of Cuban population

Background: The diffusion tensor imaging technique (DTI) combined with tractography methods, has achieved the tridimensional reconstruction of white matter tracts in the brain. It allows their characterization in vivo in a non-invasive way. However, one of the largest sources of variability originates from the location of regions of interest, is therefore necessary schemes which make it possible to establish a protocol to be insensitive to variations in drawing thereof. The purpose of this paper is to stablish a reliable protocol to reconstruct ten prominent tracts of white matter and characterize them according to volume, fractional anisotropy and mean diffusivity. Also we explored the relationship among these factors with gender and hemispheric symmetry. Methods: This study aims to characterize ten prominent tracts of white matter in a representative sample of Cuban population using this technique, including 84 healthy subjects. Diffusion tensors and subsequently fractional anisotropy and mean diffusivity maps were calculated from each subject's DTI scans. The trajectory of ten brain tracts was estimated by using deterministic tractography methods of fiber tracking. In such tracts, the volume, the FA and MD were calculated, creating a reference for their study in the Cuban population. The interactions between these variables with age, cerebral hemispheres and gender factors were explored using Repeated Measure Analysis of Variance. Results: The volume values showed that a most part of tracts have bigger volume in left hemisphere. Also, the data showed bigger values of MD for males than females in all the tracts, an inverse behavior than FA values. Conclusions: This work showed that is possible reconstruct white matter tracts using a unique region of interest scheme defined from standard to native space. Also, this study indicates differing developmental trajectories in white matter for males and females and the importance of taking gender into account in developmental DTI studies and in underlie gender-related cognitive differences
