La financiarización de las relaciones salariales. Una perspectiva internacional. Madrid, La Catarata, 2012

Para comprender las dimensiones económicas, políticas, ecológicas y, sobre todo, sociales, de la actual 'gran transformación' neoliberal en el sentido que Karl Polanyi le dio a este término, es necesario dar cuenta del proceso de financiarización, así como de sus múltiples y perniciosas consecuencias. En esta dirección se orienta la obra que aquí reseñamos La financiarización de las relaciones salariales. una perspectiva internacional

The paradoxes of dairy farmers in Catalonia (Spain) : crisis and "double bind"

Altres ajuts: Acord transformatiu CRUE-CSICAltres ajuts: Institut de Recerca i Tecnologia Agroalimentàries (IRTA) (CF616633)We want to thank Marta Terra for her contribution to the research. To Miren Etxezarreta and Luis Enrique Alonso for the comments on the text. This work was supported by the Departament d'Agricultura Ramaderia i Pesca de la Generalitat de Catalunya within the framework of an agreement between the Institute of Agrifood Research and Technology (IRTA) and UAB: Project code CF616633The article analyses the crisis and 'double bind' situation to which Catalan dairy farmers find themselves subjected. Two contradictory commands are being imposed on them: 'act as if nature does not matter and increase production because, otherwise, the abandonment of livestock activity threatens you'; and 'reduce production and protect the environment to avoid an environmental catastrophe'. In the first part of the article, we study the socioeconomic crisis facing cattle farmers. In the second, we analyse farmers' discourse on the matter as a 'double bind'. Our conclusions indicate that in order to escape this paradoxical situation and gain some autonomy with respect to industry, farmers must establish a collective conscience and unite their interests: Although the path of producer cooperativism may be among the most realistic, it is not an easy one to follow

La reinvención de la autenticidad en el contexto de la mercantilización neoliberal

Desde la últimas décadas del siglo pasado, la constatación empírica de que los límites naturales al crecimiento estaban siendo traspasados (García, 2004) supuso un incremento de la conciencia medioambiental y dio lugar a la búsqueda de respuestas de distinto tipo. El concepto de 'Parque Natural', como un intento de preservar determinados espacios, se inscribe en este contexto. En su versión neoliberal dicha preservación no implica ninguna modificación sustantiva de las reglas que impone el desarrollo económico capitalista. De este modo, se convierte en una aplicación del binomio 'desarrollo sostenible', un oxímoron (Latouche, 2006) donde se yuxtaponen dos significados contrapuestos, a saber, desarrollo económico capitalista y sostenibilidad medioambiental

The importance of new technologies in the educational process. A didactic proposal based on the application of ICT in teaching Spanish as a foreign language: mELEndien7dias

La alimentación y la nutrición infantil en el ámbito escolar: comedores escolares

Este Trabajo de Fin de Grado se ha elaborado para crear conciencia sobre la importancia de la buena alimentación y nutrición en los niños y niñas del segundo ciclo de infantil. Está compuesto por dos fases. La primera de ellas es el análisis del menú de una semana del comedor escolar del C.E.I.P. Alcalde Joaquín García (Alcalá de Guadaíra, Sevilla) y la segunda es el estudio y la observación de los hábitos alimenticios de 32 niños y niñas del segundo ciclo de infantil, elegidos mediante un muestreo aleatorio simple, que acuden a dicho comedor. Para la primera fase hemos usado el menú de este comedor escolar y lo hemos comparado con menús ideales que hemos encontrado en bibliografía para ver su adecuación; mientras que para la segunda fase hemos usado una tabla observacional compuesta con diferentes ítems donde se recogía lo que queríamos observar. Por un lado, los resultados de la primera fase han sido positivos, ya que nos encontramos ante un menú nutricionalmente adecuado para estas edades. Mientras que, los resultados de la segunda fase, nos han proporcionado tanto datos que ya esperábamos, como otros que nos han sorprendido, pero en definitiva nos han hecho ver que aún queda bastante para que muchos niños y niñas tengan unos buenos hábitos alimenticios.This End-Of-Degree Project has been done to raising awareness about the importance of a good diet and nutrition in little kids of the second cycle of Childhood Education. The project has two phases. First of them is the analysis of the weekly menu of the Alcalde Joaquín García School, located in Alcalá de Guadaíra (Seville). The second one is the study and the observation of the eating habits of 32 children of the second cycle of Childhood Education, who eat in the school canteen, chosen by a random sampling. For the first part we have used the menu of this school canteen and we have compared it with other exemplaries menus that we have found on the bibliography, to observe their adequacy. While for the second part we had prepared an observation table with different items, where we noted all we could observe. On the one hand, the results of the first phase have been positives, because we have a situation where the menu is appropiate for this age category. On the other hand, the results of the second part of the project have provided us so many details that we expected, as others that have surprised us. Ultimately, the results have made us all aware that much remains to be done with respect to the food habits of the children.Universidad de Sevilla. Grado en Educación Infanti

Encuesta “Volvemos a clase”. El impacto del confinamiento en la educación. Resultados en una muestra de niños y niñas de 5º curso de E.P.

Introducción: El confinamiento, como consecuencia de la pandemia del coronavirus, ha afectado al rendimiento escolar de los niños que se encuentran en la etapa de educación primaria debido a los casi 8 meses que estos estuvieron sin asistir al centro educativo. Objetivo: Encontrar y analizar qué factores han incidido académicamente en el alumnado de educación primaria, tanto durante el confinamiento como los primeros meses de la “nueva normalidad” dentro de las aulas. Metodología: Se adaptó una encuesta que se administró a una muestra de estudiantes de 5º curso de educación primaria (N=22). Resultados: El 82% de los alumnos tuvieron una habitación propia para realizar las actividades de aprendizaje sin que nadie le molestara. Todo el alumnado ha podido disponer de un aparato electrónico con el que seguir las clases y estudiar y todos han tenido acceso a internet. Más del 50% del estudiantado dedicó entre 1 y 3 horas diarias a las actividades de aprendizaje. Conclusiones: Para la consecución de aprendizajes escolares es indispensable que la familia brinde apoyo emocional y ejercite las habilidades cognitivas de sus hijos. La nueva normalidad puede haber afectado en otros aspectos a los niños además de cognitivamente, cómo emocional o psicológicamente. Se ha demostrado que las asignaturas más infravaloradas cómo la educación plástica y la música, han sido en las que el alumnado más ha aumentado sus calificaciones.Introduction: Confinement, as a consequence of the coronavirus pandemic, has affected the school performance of children in the primary education stage due to the almost 8 months that they were without attending school. Objective: To find and analyze what factors have had an academic impact on primary school students, both during the confinement and the first months of the "new normality" in the classroom. Methodology: A survey was adapted and administered to a sample of 5th year primary school students (N=22). Results: 82% of the students had their own room to carry out learning activities without being disturbed. All students had access to an electronic device with which to follow the classes and study and all had access to the Internet. More than 50% of the student body spent between 1 and 3 hours per day on learning activities. Conclusions: For the achievement of school learning, it is indispensable that the family provides emotional support and exercises the cognitive skills of their children. The new normality may have affected the children in other aspects besides cognitively, such as emotionally or psychologically. It has been shown that the most undervalued subjects, such as plastic education and music, have been the ones in which the students have increased their grades the most

Direct and indirect economic impacts of drought in the agri-food sector in the Ebro River basin (Spain).

The economic evaluation of drought impacts is essential in order to define efficient and sustainable management and mitigation strategies. The aim of this study is to evaluate the economic impacts of a drought event on the agricultural sector and measure how they are transmitted from primary production to industrial output and related employment. We fit econometric models to determine the magnitude of the economic loss attributable to water storage. The direct impacts of drought on agricultural productivity are measured through a direct attribution model. Indirect impacts on agricultural employment and the agri-food industry are evaluated through a nested indirect attribution model. The transmission of water scarcity effects from agricultural production to macroeconomic variables is measured through chained elasticities. The models allow for differentiating the impacts deriving from water scarcity from other sources of economic losses. Results show that the importance of drought impacts are less relevant at the macroeconomic level, but are more significant for those activities directly dependent on water abstractions and precipitation. From a management perspective, implications of these findings are important to develop effective mitigation strategies to reduce drought risk exposure

Thanatometabolomics: introducing NMR-based metabolomics to identify metabolic biomarkers of the time of death.

Death is the permanent cessation of the critical functions of the organism as a whole. However, the shutdown of a complex biological organism does not abruptly terminate at time of death. New high-throughput technologies allow the systematic investigation of the biochemical modulations occurring after death. Recent genomics studies have demonstrated that genes remain active after death, triggering upregulation of some genes and initiating feedback loops. These genes were mostly involved in pathways related to immunity, inflammation and cancer. These genetic modulations suggest many biochemical events persist after death, which can be captured using a metabolomics approach. This proof of concept work aimed to determine whether NMR spectroscopy could identify metabolomics changes occurring after death, and characterise the nature of these metabolomics modulations. High-resolution H-NMR spectroscopy was applied to six biological matrices: heart, kidney, liver, spleen, skin and white adipose tissue of ten adult mice at three different type points. Forty-three metabolites were associated with post mortem metabolomics modulations. Kidney, heart and spleen showed the highest metabolic perturbations. Conversely, skin and white adipose tissue were the least altered matrices. Early metabolic modulations were associated with energy metabolism and DNA synthesis, by contrast, late metabolomics modulations were associated with microbial metabolism. NMR has proven potential to determine the time of death based on post-mortem metabolomics modulations. This could be useful in the context of transplants, forensic studies and as internal quality control in metabolomics studies. Further investigations are required to validate these findings in humans in order to determine which compounds robustly reflect post-mortem metabolic fluctuations to accurately determine the time of death

Supercyclicity of weighted composition operators on spaces of continuous functions

[EN] Our study is focused on the dynamics of weighted composition operators defined on a locally convex space E similar to. (C( X), tp) with X being a topological Hausdorff space containing at least two different points and such that the evaluations {dx : x. X} are linearly independent in E similar to. We prove, when X is compact and E is a Banach space containing a nowhere vanishing function, that a weighted composition operator Cw,. is never weakly supercyclic on E. We also prove that if the symbol. lies in the unit ball of A(D), then every weighted composition operator can never be tp-supercyclic neither on C( D) nor on the disc algebra A(D). Finally, we obtain Ansari-Bourdon type results and conditions on the spectrum for arbitrary weakly supercyclic operators, and we provide necessary conditions for a composition operator to be weakly supercyclic on the space of holomorphic functions defined in non necessarily simply connected planar domains. As a consequence, we show that no composition operator can be weakly supercyclic neither on the space of holomorphic functions on the punctured disc nor in the punctured plane.The authors are very thankful to the referee for his/her careful reading of the manuscript and his/her valuable comments and observations.

NMR metabolomics identifies over 60 biomarkers associated with Type II Diabetes impairment in db/db mice

The rapid expansion of Type 2 Diabetes (T2D), that currently affects 90% of people suffering from diabetes, urges us to develop a better understanding of the metabolic processes involved in the disease process in order to develop better therapies. The most commonly used model for T2D research is the db/db (BKS.Cg-Dock7  +/+ Lepr /J) mouse model. Yet, a systematic H NMR based metabolomics characterisation of most tissues in this animal model has not been published. Here, we provide a systematic organ-specific metabolomics analysis of this widely employed model using NMR spectroscopy. The aim of this study was to characterise the metabolic modulations associated with T2D in db/db mice in 18 relevant biological matrices. High-resolution H-NMR and 2D-NMR spectroscopy were applied to 18 biological matrices of 12 db/db mice (WT control n = 6, db/db = 6) aged 22 weeks, when diabetes is fully established. 61 metabolites associated with T2D were identified. Kidney, spleen, eye and plasma were the biological matrices carrying the largest metabolomics modulations observed in established T2D, based on the total number of metabolites that showed a statistical difference between the diabetic and control group in each tissue (16 in each case) and the strength of the O-PLS DA model for each tissue. Glucose and glutamate were the most commonly associated metabolites found significantly increased in nine biological matrices. Investigated sections where no increase of glucose was associated with T2D include all intestinal segments (i.e. duodenum, jejunum, ileum and colon). Microbial co-metabolites such as acetate and butyrate, used as carbon sources by the host, were identified in excess in the colonic tissues of diabetic individuals. The metabolic biomarkers identified using H NMR-based metabolomics will represent a useful resource to explore metabolic pathways involved in T2D in the db/db mouse model
