The use of flipped classroom to learn a new language at the University

The Flipped Classroom model consists on a type of blended learning that reverses the traditional learning environment by delivering instructional content outside of the classroom and usually on line. Most descriptions of the flipped classroom suggest that multimedia lectures be recorded so students can view them out of class and at their own pace as homeworks ( Prober & Khan, 2013)Universidad de Málaga.

Narratives as a Didactic Resource in the Social Sciences to Teach Sustainable Development: A Study with Primary Education Students

The environment should be incorporated transversally into all human activities, especially the different areas of education. However, this is not always the case. In these pages we present a study carried out during the 2021/2022 academic year among students studying for a degree in Primary Education at the University of Cordoba, to analyze narratives as resources for teaching pupils about the environment and sustainable development, mainly through the dissemination and knowledge of the Sustainable Development Goals (SDGs). Data on the didactic experience was collected from a potential sample of 217 teachers to be via a questionnaire validated by experts, which was subjected to reliability analysis with Cronbach’s Alpha, using the SPSS program, version 25.0 for Windows. The trainee teachers reacted positively to the use of narratives as resources for teaching and learning about the environmental contents of the SDGs, considering them an ideal pedagogical resource to transmit concepts effectively, in addition to serving to develop other types of competences. Likewise, they concluded that this intervention provided significant coverage of both the theoretical and practical contents of sustainable development

PBL based on chemistry laboratories at engineering degree

Until now, the didactics used in the teaching of experimental chemistry contradicts its objective by continuing with a traditional approach and with passive didactic methods for students. Even, in virtual environments, working in the laboratory practices is basically "following a recipe" where the student does not have the opportunity to ask, make decisions or apply to their daily life. In addition to this, it happens that the "recipes" of the laboratories, in general, are repeated frequently, sometimes semester after semester. The recipes have been tested, being known to give good results, and offer no major difficulties, but the recipes do not present uncertainty for the student. On the other hand, we find the problem of the use of ICT in laboratories, which needs a change of focus. It also requires a change of environment, it is convenient to incorporate measurement processes, analyze data in real time and treat what is observed It should be remembered that Chemistry is an experimental science, therefore, laboratory works are essential and provide an enrichment for procedures and research that cannot be replaced by virtual laboratories. For all these reasons, this work focuses on the usefulness of the laboratory as a space with a problem-solving approach, which is, contextualizing problems and fulfilling a series of purposes. According to Zambrano (2007), these purposes are: ability to internalize general and specific knowledge (to know), to acquire technical and procedural skills (to know how), to develop attitudes (to know how to be) and social skills (to know how to live together). The intention of this article is to show that, including chemistry laboratories self-managed by the students themselves, generates one of the fundamental competences in our changing society, such as self-learning (learning to learn).Universidad de Málaga.

Skew-product maps with base having closed set of periodic points

In [Proc. ECIT-89, World Scientific, (1991), 177–183], A. N. Sharkovski˘ı and S.F. Kolyada stated the problem of characterization skew-product maps having zero topological entropy. It is known that, even under some additional assumptions, this aim has not been reached. In [J. Math. Anal. Appl., 287, (2003), 516–521], J. L. G. Guirao and J. Chudziak partially solved the problem in the class of skew-product maps with base map having closed set of periodic points. The present paper has two aims for this class of maps, on one hand to improve that solution showing the equivalence between the property “to have zero topological entropy” and the fact “not to be Li-Yorke chaotic in the union of the ω-limit sets of recurrent points”. On other hand, we show that the properties “to have closed set of periodic points” and “all nonwandering points are periodic” are not mutually equivalent properties, for doing this we disprove a result from Efremova of 1990

A new risk variant for multiple sclerosis at the immunoglobulin heavy chain locus associates with intrathecal IgG, IgM index and oligoclonal bands

© The Author(s), 2015. Background: Recent findings have shown a correlation between the intrathecal IgG index and variants at the immunoglobulin heavy chain (IGHC) locus in patients with multiple sclerosis (MS). Objectives: The objective of this paper is to analyse the association of the locus with MS susceptibility and its relationship with intrathecal immunoglobulin (Ig) parameters. Methods: We genotyped the rs11621145 variant, located at the IGHC locus, in 2726 patients with MS and 2133 healthy controls. Associations of intrathecal IgG and IgM indexes with rs11621145 were analysed by linear regression analysis in 538 MS patients. Results: We found that rs11621145 showed statistically significant evidence for association with susceptibility to MS (odds ratio = 0.69, p = 1.053E-09), though validation of this result in additional cohorts would be desirable. We confirmed the association between the IgG index and the rs11621145 (p = 6.85E- 07, Beta = 0.207). zFurthermore, rs11621145 was inversely correlated with IgM index (p = 7.24E-04, Beta = -0.277), and therefore marks a decreased likelihood of presenting IgM oligoclonal bands (odds ratio = 0.38, p = 2.35E-06). Conclusions: Our results suggest that the polymorphism of the IGHC locus could be altering the swiching of the Ig isotype in B cells and it may be interfering with T-dependent and T-independent antibody responses.Fondo de Investigación Sanitaria (FIS)-Fondos Europeos de Desarrollo Regional (FEDER) [grant numbers RETICS-REEM- RD12/0032/0015-RD12/0032/0005-RD12/0032/0006-RD12/0032/0009, P12/00555, PI10/01616, PI13/01527, PI13/ 01466, CP10/00526, PI12-00239]; Junta de Andalucía- Fondos Europeos de Desarrollo Regional (FEDER) [grant numbers P07-CVI-02551, P09-CTS-5218].Peer Reviewe

A sequence stratigraphic based geological model for constraining hydrogeological modeling in the urbanized area of the Quaternary Besòs delta (NW Mediterranean coast, Spain)

The Quaternary Besòs delta is located on the Mediterranean coast in NE Spain. The Besòs Delta Complex includes 3 aquifers constituted by 3 sandy and gravelly bodies, separated by lutitic units. These aquifers supply water for domestic and industrial use in this area. Management of groundwater has been problematic in the Besòs delta since the 1960s, and continues to pose major problems for subsurface engineering works in this highly urbanized region. This study seeks to demonstrate the advantages of detailed geological characterization and modeling for designing and constructing a hydrogeological model. Available information of the subsurface was compiled, integrated and homogenized in a geospatial database. The interpretation of these data enabled us to delimit geological units by means of a sequence stratigraphic subdivision. A three-dimensional facies belt-based model of the Besòs delta was built on the basis of this geological characterization. This model was used to constrain the distribution of hydraulic parameters and thus to obtain a consistent hydrogeological model of the delta, which was calibrated by data of water management and production over the last hundred years. The resulting hydrogeological model yielded new insights into water front displacements in the aquifer during the time-span considered, improving predictions in an attempt to optimize aquifer management

Nutrition Therapy in Critically Ill Patients with Liver Disease: A Narrative Review

Nutrition therapy in critically ill patients with liver disease represents a challenge for Intensive Care Units (ICUs). Nutritional status is correlated with the degree of hepatic dysfunction and the presence of malnutrition worsens outcomes in these patients. The nutritional risk that critically ill patients represent, together with the pathophysiological alterations of liver disease, especially in terms of nutrition intake and protein depletion, leads to malnutrition and sarcopenia. Nutrition therapy improves the survival of these patients; however, this is challenging since they more frequently experience difficulties with nutrition delivery. In consequence, both evaluation of nutritional status and an individualized approach seem mandatory for achieving nutrition objectives. The present narrative review discusses the importance of nutrition therapy, the recommendations of contemporary clinical practice guidelines, and a practical approach to provide the best possible nutrition therapy in patients with liver disease admitted to ICUs

El cómic como recurso para el aprendizaje histórico en el grado de educación primaria (Córdoba)

Algunos de los problemas que se encuentran en el aula cuando se imparten contenidos de historia son el bajo nivel de conocimientos que presentan el estudiantado y el exiguo interés que causa esta materia. Estos inconvenientes se unen con el predominio de métodos tradicionales, sin haberse logrado el necesario enfoque didáctico. Por este motivo, con el objetivo general de reflexionar sobre los aportes del cómic, como recurso pedagógico para ahondar en prácticas que ayuden a mejorar la enseñanza de contenidos de Ciencias Sociales se diseñó e implementó en el Grado de Educación Primaria de la Universidad de Córdoba, en España, una práctica de innovación educativa fundamentada en la utilización de cómics para la enseñanza de la historia. Tras el fin de la práctica, se recabó de información entre el estudiantado por medio de una encuesta (a través de Google Forms) sobre la validez de los cómics como recurso didáctico y su utilidad para la enseñanza de la historia, siendo posteriormente analizada con el paquete estadístico SPSS, versión 25.0 para Windows. El alumnado estimó positivamente la innovación y entendió que el cómic es una herramienta válida para comprensión de los contenidos del pasado
