La presencia de Cosima Wagner en los escritos de juventud de F. Nietzsche.

Conferencia en el congreso: NIETZSCHE CON WAGNER, NIETZSCHE CONTRA WAGNER VI CONVEGNO INTERNAZIONALE PISA, 4-6 GIUGNO 2013 Università di Pisa, Polo CarmignaniCuando nos planteamos la cuestión Nietzsche con Wagner y/o Nietzsche contra Wagner, hay un matiz en esta relación que a veces pasa desapercibido. Se trata del enigmático papel que juega Cosima Wagner en esta amistad, un papel de mediación muy activo que se aprecia cuando se lee la Correspondencia de Cosima con Nietzsche y sus Diarios. Estos, que son una continuación de la biografía de Wagner y que abarcan desde 1869 hasta la muerte del músico en 1883, nos proporcionan claves importantes para comprender la importancia de Cosima en la primera época de Nietzsche

Cambio técnico y cambio ocupacional en la economía española (1980-2000)

En España, durante los años 1980-2000, el progreso técnico ha incidido sobre el empleo en un doble sentido. Por un lado, los incrementos de la productividad del trabajo han supuesto un ahorro importante de puestos de trabajo. Por otro lado, este cambio técnico ha sido sesgado, favoreciendo la categoría de «profesionales y técnicos ». Las ocupaciones menos cualificadas han sido las segundas en crecimiento, por lo que una imagen apropiada para el caso español sería la del «reloj de arena». El modelo de «descomposición estructural por ocupaciones» explica la espectacular expansión de los profesionales y técnicos: en cada rama estos trabajadores sustituyen a otros con menor formación, al tiempo que las ramas que más crecen son precisamente las que emplean más trabajo cualificado. Los multiplicadores input-output muestran que el cambio técnico se ha propagado por todos los sectores a través del creciente consumo intermedio de bienes intensivos en tecnología

An R package for daily precipitation climate series reconstruction

Daily precipitation datasets are usually large, bulky and hard to handle, but they are of key importance in many environmental studies. We developed a tool to create custom datasets from observed daily precipitation records. Reference values (RV) are computed for each day and location using multivariate logistic regression with altitude, latitude and longitude as covariates. The operations were compiled in an Open Source R package called reddPrec. The reddPrec package consists of a set of functions used to: i) apply a comprehensive quality control over original daily precipitation datasets, flagging suspect data based on five predefined criteria; ii) fill missing values in original data series by estimating precipitation values using the 10 nearest observations for each day; and iii) create new series and gridded datasets in locations where no data were recorded

PI-based controller for low-power distributed inverters to maximise reactive current injection while avoiding over voltage during voltage sags

This paper is a postprint of a paper submitted to and accepted for publication in IET Power Electronics and is subject to Institution of Engineering and Technology Copyright. The copy of record is available at the IET Digital Library.In the recently deregulated power system scenario, the growing number of distributed generation sources should be considered as an opportunity to improve stability and power quality along the grid. To make progress in this direction, this work proposes a reactive current injection control scheme for distributed inverters under voltage sags. During the sag, the inverter injects, at least, the minimum amount of reactive current required by the grid code. The flexible reactive power injection ensures that one phase current is maintained at its maximum rated value, providing maximum support to the most faulted phase voltage. In addition, active power curtailment occurs only to satisfy the grid code reactive current requirements. As well as, a voltage control loop is implemented to avoid overvoltage in non-faulty phases, which otherwise would probably occur due to the injection of reactive current into an inductive grid. The controller is proposed for low-power rating distributed inverters where conventional voltage support provided by large power plants is not available. The implementation of the controller provides a low computational burden because conventional PI-based control loops may apply. Selected experimental results are reported in order to validate the effectiveness of the proposed control scheme.Peer ReviewedPostprint (updated version

Analyzing recommender systems for health promotion using a multidisciplinary taxonomy: A scoping review

Background: Recommender systems are information retrieval systems that provide users with relevant items (e.g., through messages). Despite their extensive use in the e-commerce and leisure domains, their application in healthcare is still in its infancy. These systems may be used to create tailored health interventions, thus reducing the cost of healthcare and fostering a healthier lifestyle in the population. Objective: This paper identifies, categorizes, and analyzes the existing knowledge in terms of the literature published over the past 10 years on the use of health recommender systems for patient interventions. The aim of this study is to understand the scientific evidence generated about health recommender systems, to identify any gaps in this field to achieve the United Nations Sustainable Development Goal 3 (SDG3) (namely, “Ensure healthy lives and promote well-being for all at all ages”), and to suggest possible reasons for these gaps as well as to propose some solutions. Methods: We conducted a scoping review, which consisted of a keyword search of the literature related to health recommender systems for patients in the following databases: ScienceDirect, PsycInfo, Association for Computing Machinery, IEEExplore, and Pubmed. Further, we limited our search to consider only English-lan-guage journal articles published in the last 10 years. The reviewing process comprised three researchers who filtered the results simultaneously. The quantitative synthesis was conducted in parallel by two researchers, who classified each paper in terms of four aspects—the domain, the methodological and procedural aspects, the health promotion theoretical factors and behavior change theories, and the technical aspects—using a new multidisciplinary taxonomy. Results: Nineteen papers met the inclusion criteria and were included in the data analysis, for which thirty-three features were assessed. The nine features associated with the health promotion theoretical factors and behavior change theories were not observed in any of the selected studies, did not use principles of tailoring, and did not assess (cost)-effectiveness. Discussion: Health recommender systems may be further improved by using relevant behavior change strategies and by implementing essential characteristics of tailored interventions. In addition, many of the features required to assess each of the domain aspects, the methodological and procedural aspects, and technical aspects were not reported in the studies. Conclusions: The studies analyzed presented few evidence in support of the positive effects of using health recommender systems in terms of cost-effectiveness and patient health outcomes. This is why future studies should ensure that all the proposed features are covered in our multidisciplinary taxonomy, including integration with electronic health records and the incorporation of health promotion theoretical factors and behavior change theories. This will render those studies more useful for policymakers since they will cover all aspects needed to determine their impact toward meeting SDG3.European Union's Horizon 2020 No 68112

Identifying, Mapping and Overcoming Genomic Impediments to Intraspecific Genetic Improvement of Upland Cotton Through Interspecific Hybridization and Introgression

Cotton, the leading natural textile fiber, develops as modified seed trichomes, produced in copious amounts by genetically elite cultivars of two domesticated New World Upland tetraploid (2n=4x=52) species, Upland cotton (Gossypium hirsutum L.) and Pima cotton (G. barbadense L.). Future cultivars must improve production sustainability, economic yield, and address the many challenges caused by global climate change. Their creation will require beneficial genetic diversity, relevant recombination, breeding, and selection. This work was undertaken [1] to better understand available diversity and natural constraints on its use, especially recombination, [2] to increase genetic diversity, and [3] to improve recombination as a tool for extracting value from diversity. Aside from transgenes and occasional mutations, induced or created, new cotton cultivars are created from fast-track breeding programs that rely exclusively on genetic variation among cultivars and elite breeding germplasm, not on wild intraspecific or interspecific accessions; cyclic re-use of elite germplasm is implicit. Using CottonSNP63K data and a long-read genomic assembly, I characterized the genomic distribution of genetic diversity by identifying, mapping, and comparing haplotypic structures and their diversity among 257 elite Upland lines and 71 non-elite G. hirsutum accessions. Independent analyses using comparable types of data for 9 at intra- and interspecific linkage mapping populations revealed their recombination patterns. Comparisons showed strong relationships between static haplotypic blocks and low experimental recombination rates. Genomic characterization of highly and lowly recombinant regions revealed significant associations and correlations between recombination and transposable element densities and biological pathways between three allotetraploid cotton species and G. hirsutum. An intriguing observation during linkage analyses was that hybridization with wild allotetraploid cotton species led to novel recombination events that disrupted long-standing haplotypic blocks. Such disruption and the recovery of novel genetic variation suggests potential for a new era in Upland cotton improvement involving extensive use interspecific hybridization to disrupt haplotypic blocks, as well as diversify genes. Indeed, this was demonstrated through recombination modeling and through the development of a chromosome segment substitution lines consisting of introgressed G. tomentosum chromatin. These findings indicate potentially major if not revolutionary ramifications for breeding Upland cotton, and likely Pima, as well
