Análisis del papel de la mujer en la ciencia y su transmisión durante la Educación Primaria.

Cuando se habla de mujeres y ciencia, la reacción inmediata es la de indicar la poca presencia de éstas en el desarrollo de la ciencia. No obstante, diversos trabajos científicos han puesto de manifiesto que, si bien a lo largo de la historia la presencia de mujeres en las disciplinas científicas y en la tecnología ha sido inferior a la de los varones, su número no es tan pequeño como se suele afirmar. Uno de los objetivos principales de este trabajo es mostrar las importantes contribuciones que las mujeres han hecho a la ciencia, así como los problemas que han tenido para ser reconocidas. Por último, se ha elaborado una propuesta didáctica con la que se pretende introducir a las mujeres científicas en el aula.Grado en Educación Primari

Arte de acción como guía para la enseñanza-aprendizaje

Treball Final de Màster Universitari en Professor/a d'Educació Secundària Obligatòria i Batxillerat, Formació Professional i Ensenyaments d'Idiomes. Codi: SAP129. Curs: 2014/2015Se entiende como arte de acción un grupo de técnicas o estilos artísticos para los que el material y soporte del acto creador no es la obra física, compuesta por los restos que la acción genera, sino la propia acción. Poniendo como punto de partida esta definición y su símil con la educación, el presente trabajo final del Máster en Profesorado de Educación Secundaria se adentra en la aplicación de las características formales del arte de acción para su aplicación en el proceso de enseñanza-aprendizaje. Tal confluencia entre arte de acción y enseñanza-aprendizaje, se lleva a cabo mediante un exhaustivo proceso de Investigación-Acción del que nace la GuiADA. Mediante esta guía, abierta a nuevas adaptaciones, se traza un plan para llevar a cabo las características formales del arte de acción al contexto educativo, dando sentido y potenciando todo aquello que acontece en el proceso de E-A

Chapter Career Calling: Lights and Shadows

In this moment the policies on lifelong guidance, recognition of learning and skills certification seem more working on who should do what and not on how make. It would be desirable to create links between the various providers of training, education and business, allowing for a reframing of orientation processes and of identification and certification of skills. All these practices can reduce distances for those who are likely to remain at the margins of education, training and work (Neet and over fifty

Role of the glassy dynamics and thermal mixing in the dynamic nuclear polarization and relaxation mechanisms of pyruvic acid

The temperature dependence of $^1$H and $^{13}$C nuclear spin-lattice relaxation rate $1/T_1$ has been studied in the 1.6 K - 4.2 K temperature range in pure pyruvic acid and in pyruvic acid containing trityl radicals at a concentration of 15 mM. The temperature dependence of $1/T_1$ is found to follow a quadratic power law for both nuclei in the two samples. Remarkably the same temperature dependence is displayed also by the electron spin-lattice relaxation rate $1/T_{1e}$ in the sample containing radicals. These results are explained by considering the effect of the structural dynamics on the relaxation rates in pyruvic acid. Dynamic nuclear polarization experiments show that below 4 K the $^{13}$C build up rate scales with $1/T_{\text{1e}}$, in analogy to $^{13}$C $1/T_1$ and consistently with a thermal mixing scenario where all the electrons are collectively involved in the dynamic nuclear polarization process and the nuclear spin reservoir is in good thermal contact with the electron spin system.Comment: 14 pages, 13 figure

Nitro-fatty acid formation and metabolism

Nitro-fatty acids (NO 2 -FA) are pleiotropic modulators of redox signaling pathways. Their effects on inflammatory signaling have been studied in great detail in cell, animal and clinical models primarily using exogenously administered nitro-oleic acid. While we know a considerable amount regarding NO 2 -FA signaling, endogenous formation and metabolism is relatively unexplored. This review will cover what is currently known regarding the proposed mechanisms of NO 2 -FA formation, dietary modulation of endogenous NO 2 -FA levels, pathways of NO 2 -FA metabolism and the detection of NO 2 -FA and corresponding metabolites.Fil: Buchan, Gregory J..

A focused framework for emulating modal proof systems

International audienceSeveral deductive formalisms (e.g., sequent, nested sequent, labeled sequent, hyperse-quent calculi) have been used in the literature for the treatment of modal logics, and some connections between these formalisms are already known. Here we propose a general framework, which is based on a focused version of the labeled sequent calculus by Negri, augmented with some parametric devices allowing to restrict the set of proofs. By properly defining such restrictions and by choosing an appropriate polarization of formulas, one can obtain different, concrete proof systems for the modal logic K and for its extensions by means of geometric axioms. In particular, we show how to use the expressiveness of the labeled approach and the control mechanisms of focusing in order to emulate in our framework the behavior of a range of existing formalisms and proof systems for modal logic

Robust 24 Hours ahead Forecast in a Microgrid: A Real Case Study

Forecasting the power production from renewable energy sources (RESs) has become fundamental in microgrid applications to optimize scheduling and dispatching of the available assets. In this article, a methodology to provide the 24 h ahead Photovoltaic (PV) power forecast based on a Physical Hybrid Artificial Neural Network (PHANN) for microgrids is presented. The goal of this paper is to provide a robust methodology to forecast 24 h in advance the PV power production in a microgrid, addressing the specific criticalities of this environment. The proposed approach has to validate measured data properly, through an effective algorithm and further refine the power forecast when newer data are available. The procedure is fully implemented in a facility of the Multi-Good Microgrid Laboratory (MG(Lab)(2)) of the Politecnico di Milano, Milan, Italy, where new Energy Management Systems (EMSs) are studied. Reported results validate the proposed approach as a robust and accurate procedure for microgrid applications

Asymmetry of parietal interhemispheric connections in humans

Visuospatial abilities are preferentially mediated by the right hemisphere. Although this asymmetry of function is thought to be due to an unbalanced interaction between cerebral hemispheres, the underlying neurophysiological substrate is still largely unknown. Here, using a method of trifocal transcranial magnetic stimulation, we show that the right, but not left, human posterior parietal cortex exerts a strong inhibitory activity over the contralateral homologous area by a short-latency connection. We also clarify, using diffusion-tensor magnetic resonance imaging, that such an interaction is mediated by direct transcallosal projections located in the posterior corpus callosum. We argue that this anatomo-functional network may represent a possible neurophysiological basis for the ongoing functional asymmetry between parietal cortices, and that its damage could contribute to the clinical manifestations of neglect
