Intersectionality on the perception of health in two cross-national surveys (WVS and EVS)

This article focuses on the health perceptions of people across social strata and nations using the combined dataset of the World Values Survey and the European Values Study (EVS/WVS). An intercategorical intersectional analysis model was developed to examine the social determinants underlying differences in health perceptions. Using logistic regression of the interactions between sex, age, level of educational attainment and income, we calculated the impact of these variables (main effects) and their interactions within the intersecting categories on health perceptions. The group with the best perception of their health includes men aged 16-49, with a high income and an upper-middle level of education. Comparative analysis has been carried out to identify differences in the influence of intersectional categories across countries. Of particular relevance is the number of Eastern European countries where the perception of people aged 50 and over with low income is very poor

Norm-attaining composition operators on Lipschitz spaces

Every composition operator C_{\varphi} on the Lipschitz space Lip_0(X) attains its norm. This fact is essentially known and we give in this paper a sequential characterization of the extremal functions for the norm of C_{\varphi} on Lip_0(X). We also characterize the norm-attaining composition operators C_{\varphi} on the little Lipschitz space lip_0(X) which separates points uniformly and identify the extremal functions for the norm of C_{\varphi} on lip_0(X). We deduce that compact composition operators on lip_0(X) are norm-attaining whenever the sphere unit of lip_0(X) separates points uniformly. In particular, this condition is satisfi ed by spaces of little Lipschitz functions on Hölder compact metric spaces (X,d^{\alpha}) with 0<\alpha<1

Mathematical model to predict separation of C-phycocyanin from Spirulina sp. using an expanded-bed vortex flow reactor and its subsequent scaling-up

This study presents a novel single-step method for the separation and purification of C-phycocyanin (CPC) extracted from dry Spirulina sp. using an expanded-bed vortex flow reactor (EB-VFR). The EB-VFR employed a DA405/EB polymethacrylate resin functionalized with tertiary amino groups, expanded by axial flow and stabilized by a laminar Taylor vortex generated by a central rotating cylinder. The CPC extract (2.3 g/L) was processed through the reactor (settled resin height: 20 cm) at rotation speeds of 0, 50, 100, and 150 rpm with an axial flow rate of 200 cm/h, followed by elution with a 500 mM phosphate buffer. At 100 rpm, the CPC yield reached 45%, while purity increased from 0.50 to 2.0 and the concentration to 3.3 g/L, demonstrating the reactor’s ability to achieve simultaneous concentration and purification. A mathematical model was developed to correlate operating parameters with dimensionless numbers (Taylor and Reynolds), providing quantitative predictions of CPC adsorption and elution performance. Experimental results obtained using radially and axially scaled-up EB-VFRs were in good agreement with the model predictions, confirming its applicability in process design and scale-up. These findings highlight the EB-VFR as an effective and scalable platform for the recovery of bioactive proteins from cyanobacteria, enabling efficient separation under dynamic hydrodynamic conditions. The approach offers significant potential for sustainable bioprocessing by integrating adsorption, washing, and elution into a single continuous operation with controllable hydrodynamic expansion and mixing behavior

The Political Dimension of Myles na gCopaleen’s Cruiskeen Lawn

EN: This book meticulously analyzes Cruiskeen Lawn, a popular column published in The Irish Times by Irish writer Myles na gCopaleen (real name Brian O'Nolan, though also known as Flann O'Brien), from 1940 to 1966. Cruiskeen Lawn was a comic literary column devoted to offering a sharp and incisive portrait of mid-twentieth century Ireland. Conscious of the historical significance of twenty-six years’ worth of political commentary by a renowned intellectual figure such as O’Nolan, this book examines the total of 4,032 newspaper articles that compose Cruiskeen Lawn with a twofold aim: firstly, to understand Myles na gCopaleen’s Cruiskeen Lawn as a work of political commentary and to view the column as a historical account of mid-twentieth century Ireland; and secondly, to determine O’Nolan’s own political philosophy through a close reading of his opinions on the political events discussed throughout the book. ES: Este libro analiza minuciosamente Cruiskeen Lawn, una popular columna publicada en The Irish Times por el escritor irlandés Myles na gCopaleen (nombre real Brian O'Nolan, aunque también conocido como Flann O'Brien), entre 1940 y 1966. Cruiskeen Lawn era una columna literaria de carácter cómico dedicada a ofrecer un retrato agudo y penetrante de la Irlanda de mediados del siglo XX. Consciente de la importancia histórica que suponen veintiséis años de comentarios políticos firmados por una figura intelectual de renombre como O’Nolan, este libro examina el conjunto de los 4.032 artículos periodísticos que componen Cruiskeen Lawn con un doble objetivo: en primer lugar, comprender la Cruiskeen Lawn de Myles na gCopaleen como una obra de comentario político y considerar la columna como un testimonio histórico de la Irlanda de mediados del siglo XX; y, en segundo lugar, determinar la propia filosofía política de O’Nolan mediante una lectura atenta de sus opiniones sobre los acontecimientos políticos tratados a lo largo del libro

Las fundaciones en el marco de las empresas sociales. El caso de las fundaciones bancarias

Actualmente se está tramitando en sede parlamentaria el denominado Proyecto de Ley integral de impulso de la economía social, entre cuyas novedades está el reconocimiento e incorporación de las denominadas empresas sociales al ámbito de la economía social. El objetivo del presente trabajo es, por un lado, hacer un análisis científico del texto propuesto para la futura Ley integral en lo que concierne a las empresas sociales; por otro lado, dar una visión del acomodo de las fundaciones con actividad económica y, en especial las bancarias, al ámbito de la economía social y, en su caso, al de las empresas sociales; y, finalmente, ofrecer información del proceso de creación de las fundaciones bancarias en España, partiendo de su modelo italiano que es el que se ha tomado del Derecho comparado, indicando los pasos y fases de transformación de las cajas de ahorros en fundaciones bancarias, que, previsiblemente se verán apartadas de la futura concepción de empresas sociales que se está planteando en el ámbito legislativo nacional

Bitcoin as an econometric tool for asset co-movement: therelation index

This study proposes a methodological strategy composed of econometric techniques andtime series modelling to analyse the dynamic asynchrony between Bitcoin and a basket oftraditional sustainable financial assets and emerging markets over a 10-year period markedby major economic and financial changes. The centrepiece of this proposal is the Rela-tion Index that combines vector autoregression and detrended cross-correlation analysis tocapture linear and nonlinear dependencies, causality, and time-scale sensitive correlations.Thus, this research fills existing gaps in understanding cross-market interdependenciesby integrating cryptocurrencies, sustainability indices, and emerging economies into arigorous multivariate time series framework. Sustainability indices, emerging markets andBitcoin have shown a growing correlation since 2020, with both interest rates and Bitcoinhaving strong autoregressive components. The findings indicate that emerging market eq-uities have undergone a structural shift towards synchronisation with global risk assets,with a correlation index that frequently exceeds 0.6 in periods of systemic stress. Thisevolution highlights the decline in the advantages offered by diversification in developedand developing economies in a complex and interrelated financial environmen

Utilidad de la enseñanza gramatical percibida por futuros docentes e intención de replicar modelos didácticos: el componente motivacional como causa explicativa

Ante la crítica sobre la limitada funcionalidad de la enseñanza gramatical, este estudio adopta un enfoque metacognitivo para analizar la utilidad y la motivación asociadas al aprendizaje de la gramática en la formación docente. Se analizaron las opiniones de 355 futuros maestros de Educación Primaria españoles mediante el cuestionario ExCOGE, con el fin de examinar: a) la utilidad percibida de la gramática para el desarrollo de destrezas comunicativas y el aprendizaje de otras lenguas, y b) el papel de la motivación como factor explicativo y predictor de la reproducción de modelos de enseñanza gramatical heredados. Los resultados indican que los participantes atribuyen a la gramática una mayor incidencia en la mejora de la expresión escrita, seguida de la expresión oral y del aprendizaje de otras lenguas. Asimismo, quienes se declaran motivados por el aprendizaje gramatical valoran más positivamente su utilidad y muestran, de forma significativa, una mayor intención de reproducir el modelo de enseñanza recibido. In response to sustained criticism regarding the limited functionality of grammar teaching, this study adopts a metacognitive approach to examine the perceived usefulness of grammar and the motivation associated with grammar learning in teacher education. The opinions of 355 Spanish pre-service primary school teachers were analysed using the ExCOGE questionnaire in order to examine: a) the perceived usefulness of grammar for the development of communicative skills and for the learning of additional languages, and b) the role of motivation as an explanatory factor and as a predictor of the intention to reproduce inherited models of grammar teaching. The findings indicate that participants attribute the greatest impact of grammar learning to improvements in written expression, followed by oral expression and the learning of other languages. Furthermore, those pre-service teachers who report having been motivated by grammar learning evaluate its usefulness more positively and, more significantly, express a stronger intention to reproduce the teaching model they experienced
