Análisis de las estrategias motivacionales en los programas de intervención para agresores de pareja: el impacto de las metas de cambio
Get PDFLos participantes que acuden por mandato judicial a programas de intervención con agresores de pareja suelen mostrar una elevada resistencia a la intervención, altas tasas de abandono y baja motivación al cambio. Los programas que incorporan estrategias motivacionales ajustadas a los riesgos y necesidades delos participantes han mostrado resultados prometedores. Una de estas estrategias es el establecimiento de metas de cambio. Los objetivos de este estudio fueron evaluar las diferencias al inicio de la intervención entre los participantes que se establecieron metas y los que no en variables sociodemográficas, de proceso (i.e., estadio de cambio, motivación al cambio de conductas violentas), el riesgo de reincidencia y la violencia autoinformada, y examinar las diferencias al finalizar la intervención entre ambos grupos en las variables de proceso y el riesgo de reincidencia. Además, se examinó la asociación entre el establecimiento de metas y la mejora de dichos resultados de intervención. Los resultados mostraron que los participantes que se establecieron una meta de cambio eran más jóvenes, con empleo en activo, con un mayor nivel de ingresos anual, un mayor nivel de motivación al cambio, una mayor tasa de violencia física autoinformada y un mayor estadio de cambio al inicio de la intervención. Al finalizar la intervención, los participantes que se establecieron una meta de cambio presentaron un mayor nivel de motivación al cambio, mayor dosis de intervención y participación, se encontraron en un estadio de cambio más avanzado y mostraron menores tasas de abandono de la intervención. Estos resultados sugieren que el establecimiento de metas podría ser una estrategia motivacional efectiva que se ajusta a los factores de riesgo y necesidades de los participantes para reducir la resistencia a la intervención, aumentar la motivación al cambio y el compromiso con la intervención de los agresores de pareja

Modular characters, hall subgroups, and normal complements
Get PDFIf H is a Hall subgroup of a finite group G, it was proven in 1989 using the classification of finite simple groups that all the irreducible complex characters of H extend to G if and only if there is such that and . In this note we offer a modular version of this result under more general hypotheses
New Insights in Luminescence and Quenching Mechanisms of Ag2S Nanocrystals through Temperature-Dependent Spectroscopy
Get PDFBright near-infrared-emitting Ag2S nanocrystals (NCs) are used for in vivo temperature sensing relying on a reversible variation in intensity and photoluminescence lifetime within the physiological temperature range. Here, to gain insights into the luminescence and quenching mechanisms, we investigated the temperature-dependent luminescence of Ag2S NCs from 300 to 10 K. Interestingly, both emission and lifetime measurements reveal similar and strong thermal quenching from 200 to 300 K, indicating an intrinsic quenching process that limits the photoluminescence quantum yield at room temperature, even for perfectly passivated NCs. The low thermal quenching temperature, broadband emission, and multiexponential microsecond decay behavior suggest the optical transition involves strong lattice relaxation, which is consistent with the recombination of a Ag+-trapped hole with a delocalized conduction band electron. Our findings offer valuable insights for understanding the optical properties of Ag2S NCs and the thermal quenching mechanism underlying their temperature-sensing capabilities
El Derecho de sociedades ante la transición ecológica. Primeras reflexiones de la Sociedad Cooperativa como comunidad energética
No full textThis article is a first legal approach to the energy communities as a new operator in the energy market. It analyzes Directives 2018/2001 and 2019/944, which introduce the 'Renewable Energy Community' and 'Citizen Energy Community' and which do not refer to any particular category. The Spanish legal system has not approved a regulation that develops this figure. However, the characteristics of energy communities relate to the cooperative principles of the ICA. That is why this study focuses on analyzing the cooperative, in particular, the consumer cooperative, as the most suitable alternative to articulate the energy community

Improvement in left atrial strain following ferric carboxymaltose in heart failure: an analysis of the Myocardial-IRON trial.
Get PDFAims Iron deficiency (ID) is associated with an impaired cardiac function and remodelling in heart failure (HF). Treatment with ferric carboxymaltose (FCM) has been showed recently to improve biventricular systolic function and ventricular strain parameters in patients with HF with reduced ejection fraction and ID, but there is no evidence on the benefit of FCM on the left atrium (LA). In this study, we aimed to evaluate the effect of FCM on LA longitudinal strain (LA-LS). Methods and results This is a post hoc subanalysis of a double-blind, placebo-controlled, randomized clinical trial that enrolled 53 ambulatory patients with HF, left ventricular ejection fraction (LVEF) < 50%, and ID [Myocardial-IRON trial (NCT03398681)], treated with FCM or placebo. Cardiac magnetic resonance-featured tracking (CMR-FT) strain changes were evaluated before and 7 and 30 days after randomization using linear mixed regression analysis. The median age of the sample was 68 years (interquartile range: 64-76), and 20 (69%) were men. Mean ± standard deviation of LVEF was 39 ± 11%, and most (97%) were in stable New York Heart Association class II. At baseline, mean LA-LS was 8.9 ± 3.5%. At 30 days, and compared with placebo, LA-LS significantly improved in those allocated to FCM treatment arm (LA-LS = 12.0 ± 0.5 and 8.5 ± 0.6, respectively; Δ 3.55%, P < 0.001). Conclusions In patients with stable HF, LVEF < 50%, and ID, treatment with FCM was associated with short-term improvements in LA-LS assessed by CMR-FT. Future works should assess the potential benefit of iron repletion on LA function
Expresiones verbales de desagrado: análisis y aplicación para actividades didácticas de estudiantes chinos de español como lengua extranjera
Get PDFEste trabajo investiga la relación entre las emociones, particularmente el desagrado, y el aprendizaje del español como lengua extranjera (ELE) en estudiantes chinos. Mediante una revisión teórica y una investigación empírica, se analiza cómo las emociones impactan la dinámica del aula y el rendimiento académico, enfocándose en la expresión verbal del desagrado y cómo estas emociones influyen en el proceso de aprendizaje.
El estudio destaca que las emociones son elementos centrales en el aprendizaje de lenguas extranjeras, influyendo en la motivación, las estrategias de aprendizaje y la confianza de los estudiantes. En particular, el desagrado, aunque inicialmente un obstáculo, puede convertirse en un motor de aprendizaje cuando se maneja adecuadamente. El análisis empírico muestra que los estudiantes chinos enfrentan diversos retos emocionales, como ansiedad, inseguridad y frustración, originados por la falta de vocabulario emocional, diferencias culturales y la carga cognitiva de las actividades lingüísticas. A partir de estos hallazgos, se proponen estrategias pedagógicas que incluyen el establecimiento de objetivos integrales que combinen el desarrollo lingüístico y emocional, la creación de un ambiente inclusivo y la retroalimentación positiva.
Este trabajo contribuye a una comprensión más profunda de la dimensión emocional en el aprendizaje de ELE, promoviendo prácticas pedagógicas que favorezcan un aprendizaje más efectivo y sostenible
Describing Otherness in Captives' Autobiographies in the Late Sixteenth and Early Seventeenth Centuries
Get PDFThe essay explores the description of Otherness in the autobiographies of three former Christian captives from the late sixteenth and early seventeenth centuries. In these texts, authors described their experiences in the Islamic societies where they were enslaved, offering insights into Islamic geography and culture. However, these descriptions were also influenced by prevailing ideas and the authors' need to align their narratives with the hegemonic discourse, thereby perpetuating and crafting biased depictions of the Other. Understanding the motivations that guided the construction of memory in these autobiographies is crucial for a comprehensive grasp of their objectives. These objectives are closely intertwined with the authors' experiences in Islamic societies and their aspirations for reintegration into Christian ones, where they produced their writings after escaping captivity
Testing experimental designs in liquid chromatography (II): Influence of the design geometry on the prediction performance of retention models
Get PDFIn liquid chromatography, the reliability of predictions carried out with retention models depends critically on the quality of the training experimental design. The search of the best design is more complex when gradient runs are used instead of isocratic experiments. In Part I of this work, a general methodology based on the error propagation theory was developed and validated for assessing the quality of training designs involving gradients. The treatment relates the mathematical properties of a retention model with the geometry of the training designs and their subsequent predictions. In that work, only five usual designs were considered. Part II investigates in detail the effects on predictions when the features of the training design (number and distribution of the experiments, initial and final modifier content, gradient slope(s), and location of gradient nodes and pulses) are varied systematically. Several groups of related designs containing one or more isocratic steps, linear or multi-linear gradients, or mixed isocratic/gradient runs, among others (in total 38 designs) were evaluated. Box and whiskers and triple plots of expected relative uncertainties were used to evidence the differences in prediction performance. The purpose was to give recommendations to construct designs with good prediction performance. The best designs sample (considering all runs) concentrations as diverse as possible, at any gradient time
