Construyendo opera seria en las cortes de la península ibérica: repertorio de Metastasio para España y Portugal

The exceptional reception of Pietro Metastasio’s works during the eighteenth century, all over Europe and in the Iberian Peninsula in particular, is well documented. Due to that unparalleled success, it is possible to ascertain Spain and Portugal’s participation in international, contemporary tastes and artistic webs, applicable to both composers and performers. However, this internationalisation needs to be nuanced, as some characteristics of the repertoire specifically written for the Peninsula indicate that their court audiences may have had expectations, both social and strictly musical, different from those of the public in opera theatres elsewhere in the continent. In this light, this article investigates in what ways the style of five composers in the international scene —Perez, Galuppi, Jommelli, Conforto, and Corselli— varied when commissioned to write opera seria for the Iberian courts. The statistical analysis of fifteen settings especially written for the court theatres in Madrid and Lisbon, in comparison to the average data extracted from a corpus of 2,404 arias from 126 versions of a select number of Metastasian librettos, allows us to evaluate some particular usages regarding key, metre, tempo, and treatment of the vocal part. In this manner, through quantitative analysis, this article places eighteenth-century Iberian music production and consumption in the context of European opera seria, at the same time that it ultimately sets forth that its unique musical characteristics were also partly dependent on local musical customs, gender stereotypes, and personal idiosyncrasies alike.La excepcional acogida de las obras de Pietro Metastasio en el siglo XVIII, en Europa y en la península ibérica en particular, está ampliamente documentada. Debido a este éxito sin parangón, es posible afirmar que España y Portugal participaron de los gustos y redes artísticas internacionales del momento. Sin embargo, esta internacionalización ha de ser matizada, ya que el repertorio escrito específicamente para la península muestra que las audiencias cortesanas peninsulares pudieron tener expectativas diferentes a las del público de otros teatros en el resto del continente. Por ello, este trabajo investiga en qué formas varió el estilo de cinco compositores de talla internacional —Perez, Galuppi, Jommelli, Conforto y Corselli— a la hora de enfrentarse a los encargos de opera seria para las cortes ibéricas. El análisis estadístico de quince versiones compuestas específicamente para Madrid y Lisboa nos permite evaluar, en comparación con las tendencias generales de un corpus de 2.404 arias tomadas de 126 versiones de libretos metastasianos, algunos usos locales en cuanto a tonalidad, compás, tempo y tratamiento de la parte vocal. A través del análisis cuantitativo, este artículo sitúa a la producción y el consumo de música en el siglo XVIII peninsular dentro del contexto de la opera seria europea, al mismo tiempo que, en última instancia, propone que sus características musicales también dependieron en parte de las costumbres musicales y los estereotipos de género del público de las cortes peninsulares, así como de algunos rasgos específicos de los compositores y los cantantes

Evolución de los pacientes con diagnóstico cardiológico prenatal

Las cardiopatías congénitas tienen una incidencia de 9/1000 nacidos vivos, siendo graves en la cuarta parte de los casos. El objetivo del estudio consiste en describir las características de las pacientes remitidas a la consulta de Cardiología Perinatal del Hospital Universitario del Río Hortega. Se realizó un estudio retrospectivo, descriptivo en el que se estudió a una población de mujeres de 237, con un número total de consultas de 478 entre 2007 hasta 2016. La estadística descriptiva de la muestra se realizó por medio del software STATGRAPHICS Centurión XVII. Se realizaron un total de 478 consultas con 237 pacientes diferentes, de distintas provincias de Castilla y León. De las pacientes atendidas un 37,55% vinieron por sospecha de alteración morfológica, seguido de 27,85% por antecedentes familiares, un 16,3% por patología fetal, un 9,28% a demanda, un 5,91% por arritmia, un 1,69% por madre cardiópata y un 1,69% por patología materna. De los cuales el diagnóstico preprenatal ha sido 54,01% normal, 31,22% cardiopatía, 11,39% variante de la normalidad y 3,38% de arritmias. Se realizaron en 15,38% interrupciones voluntarias del embarazo (16 pacientes). Tras la confirmación el 88,89% han nacido en el hospital de origen; un 10% han nacido en el hospital de referencia, un total de 13 pacientes, siendo necesaria cirugía neonatal en 11 de ellos, en uno de ellos se realizó un trasplante cardiaco, 1 cirugía fuera del periodo neonatal y 1 estabilidad clínica sin intervencionismo con una evolución satisfactoria salvo 4 exitus tras cirugía por complicaciones con su enfermedad; y un 1,71%han sido exitus intraútero. Una de las razones más importantes que avalan la ecocardiografía fetal como herramienta para el screening cardiológico prenatal es la posibilidad de realizar un diagnóstico precoz y por consiguiente poder planificar el curso del embarazo y el lugar y el momento del parto si se decide continuar. La capacidad diagnóstica de cardiopatías congénitas se ve mejorada por el trabajo conjuntos entre unidades de cardiología pediátrica y servicios de obstetricia.Grado en Medicin

Approximations to an integrated model of eating disorders and muscle dysmorphia among university male students in Argentina

Male body dissatisfaction has been associated with drive for muscularity and, in extreme cases, with the clinical condition referred to as muscle dysmorphia (MD). Although recent research suggests that MD is closely linked to eating disorders (EDs), it is classed as a subtype of body dysmorphic disorder. A cross-sectional study was conducted among 402 university male students in Buenos Aires to examine common factors in the development of EDs and MD. Multiple regression analyses were performed to assess the predictive value of the investigated variables. For both conditions, the models accounted for 48 percent of the variance and were predicted by a similar set of variables. The results support the inclusion of MD within the EDs spectrum

Optimizing Feature Extraction for Symbolic Music

This paper presents a comprehensive investigation of existing feature extraction tools for symbolic music and contrasts their performance to determine the set of features that best characterizes the musical style of a given music score. In this regard, we propose a novel feature extraction tool, named musif, and evaluate its efficacy on various repertoires and file formats, including MIDI, MusicXML, and **kern. Musif approximates existing tools such as jSymbolic and music21 in terms of computational efficiency while attempting to enhance the usability for custom feature development. The proposed tool also enhances classification accuracy when combined with other sets of features. We demonstrate the contribution of each set of features and the computational resources they require. Our findings indicate that the optimal tool for feature extraction is a combination of the best features from each tool rather than those of a single one. To facilitate future research in music information retrieval, we release the source code of the tool and benchmarks.Comment: Published at ISMIR 202

Effect of nanostructured ceria as support for the iron catalysed hydrogenation of CO2 into hydrocarbons.

This paper demonstrates the key role of the property-structure relationship of the support on iron/ceria catalysts on the hydrocarbon selectivity and olefin-to-paraffin ratio for the direct hydrogenation of carbon dioxide into hydrocarbons. The effect is directly related to the reducibility of the different nanostructured ceria supports and their interaction with the iron particles. Herein, we demonstrate that the iron-based catalysts can be modified not only by the addition of promoters, commonly reported in the literature, but also by careful control of the morphology of the ceria support.The authors thanks the UK Engineering and Physical Science Research Council (EPSRC, grant numbers: EP/L020432/2 and EP/G03768X/1).This is the final version of the article.

To burn-out or not to burn-out: A cross-sectional study in healthcare professionals in Spain during COVID-19 pandemic

Objective To assess the prevalence of burn-out syndrome in healthcare workers working on the front line (FL) in Spain during COVID-19. Design Cross-sectional, online survey-based study. Settings Sampling was performed between 21st April and 3rd May 2020. The survey collected demographic data and questions regarding participants' working position since pandemic outbreak. Participants Spanish healthcare workers working on the FL or usual ward were eligible. A total of 674 healthcare professionals answered the survey. Main outcomes and measures Burn-out syndrome was assessed by the Maslach Burnout Inventory-Medical Personnel. Results Of the 643 eligible responding participants, 408 (63.5%) were physicians, 172 (26.8%) were nurses and 63 (9.8%) other technical occupations. 377 (58.6%) worked on the FL. Most participants were women (472 (73.4%)), aged 31-40 years (163 (25.3%)) and worked in tertiary hospitals (>600 beds) (260 (40.4%)). Prevalence of burn-out syndrome was 43.4% (95% CI 39.5% to 47.2%), higher in COVID-19 FL workers (49.6%, p<0.001) than in non-COVID-19 FL workers (34.6%, p<0.001). Women felt more burn-out (60.8%, p=0.016), were more afraid of self-infection (61.9%, p=0.021) and of their performance and quality of care provided to the patients (75.8%, p=0.015) than men. More burn-out were those between 20 and 30 years old (65.2%, p=0.026) and those with more than 15 years of experience (53.7%, p=0.035). Multivariable logistic regression analysis revealed that, working on COVID-19 FL (OR 1.93; 95% CI 1.37 to 2.71, p<0.001), being a woman (OR 1.56; 95% CI 1.06 to 2.29, p=0.022), being under 30 years old (OR 1.75; 95% CI 1.06 to 2.89, p=0.028) and being a physician (OR 1.64; 95% CI 1.11 to 2.41, p=0.011) were associated with high risk of burn-out syndrome. Conclusions This survey study of healthcare professionals reported high rates of burn-out syndrome. Interventions to promote mental well-being in healthcare workers exposed to COVID-19 need to be immediately implemented.publishersversionpublishe

In-flow photocatalytic oxidation of NO on glasses coated with nanocolumnar porous TiO2 thin films prepared by reactive sputtering

The magnetron sputtering technique has been successfully employed for the preparation of porous TiO2 thin films on soda-lime glasses by means of an oblique angle deposition strategy. The morphology of the thin layers is affected by the deposition parameters, such as, the angle with respect to the target, applied power, total pressure, oxygen pressure and deposition time. It has been shown that 60–65° angles, lead to a compromise between the porosity, the level of oxidation and the thickness of the film. High total pressures of the deposition process result in less dense coatings of greater porosity. Moreover, the oxygen flow during the deposition process must be carefully adjusted for each set of deposition conditions, in order to achieve an optimum degree of oxidation. The evaluation of coated-glasses in the in-flow photocatalytic oxidation of nitrogen oxide has shown that the presence of a porous film is essential to achieve photocatalytic activity. The best performing coated-glass was able to reduce the NO concentration ca. 20% for 5 h. SEM and TEM images of this film show a microstructure composed of nanometric grains and a tilted columnar structure. Nanocrystal electron diffraction, XRD and Raman spectroscopy have confirmed the deposition of TiO2 anatase
