Educación Histórica y competencias educativas en la formación universitaria

Con este trabajo se pretende favorecer la cercanía del alumnado del Máster de profesorado de Secundaria de la Universidad de Córdoba con respecto al concepto de patrimonio y la implementación de los itinerarios didácticos en su formación universitaria. Para nuestra propuesta se establece un aprendizaje interactivo de enseñanza que dé la posibilidad a los estudiantes de trabajar de manera investigativa las salidas del aula. La muestra de estudio la componen 107 alumnos de la asignatura Aprendizaje y enseñanza de las materias correspondientes en Ciencias Sociales: Geografía e Historia. De acuerdo, con los resultados del pre-test y el post-test la comprensión del espacio geográfico, su proceso de formación histórica y los modos de vida en él desarrollados, han sido de gran utilidad para vincular al alumnado del MAES con su entorno inmediato y también contribuir al entendimiento de las dinámicas históricas que lo configuran

Flipped classroom to teach digital skills during Covid-19

This paper deals with the implementation of flipped learning as a didactic method and its use through the Moodle platform. For this purpose, a quantitative research was carried out with the intention of analyzing the perceptions of new teachers in the acquisition of digital competences that they acquire during their teaching and learning process. The sample is made up of three groups of students in the subject Didactics of Social Sciences in the third year of primary education. The results obtained show that active learning methodologies promote digital literacy in higher education and the improvement of good teaching practices. In this way, through this research, students updated their use of new educational platforms, given the lack of initial training in digital literacy. In short, we can conclude that flipped learning is a useful and innovative teaching method that combines face-to-face and online learning for the education and training of new teachers

Distinct roles of apolipoprotein components within the trypanosome lytic factor complex revealed in a novel transgenic mouse model

Humans express a unique subset of high-density lipoproteins (HDLs) called trypanosome lytic factors (TLFs) that kill many Trypanosoma parasite species. The proteins apolipoprotein (apo) A-I, apoL-I, and haptoglobin-related protein, which are involved in TLF structure and function, were expressed through the introduction of transgenes in mice to explore their physiological roles in vivo. Transgenic expression of human apolipoprotein L-I alone conferred trypanolytic activity in vivo. Coexpression of human apolipoprotein A-I and haptoglobin-related protein (Hpr) had an effect on the integration of apolipoprotein L-I into HDL, and both proteins were required to increase the specific activity of TLF, which was measurable in vitro. Unexpectedly, truncated apolipoprotein L-I devoid of the serum resistance gene interacting domain, which was previously shown to kill human infective trypanosomes, was not trypanolytic in transgenic mice despite being coexpressed with human apolipoprotein A-I and Hpr and incorporated into HDLs. We conclude that all three human apolipoproteins act cooperatively to achieve maximal killing capacity and that truncated apolipoprotein L-I does not function in transgenic animals

Role of Mo in catalysts based on noble metals in hydrodeoxygenation reactions

The use of bio-energy as a renewable alternative to fossil fuels is nowadays attracting more and more attention. The bio-fuel from biomass seems to be a potential energy substitute for fossil fuels since it is a renewable resource that could contribute to sustainable development and global environmental preservation and it appears to have significant economic potential1. The problem is its high oxygen content, which gives undesirable properties for combustion. To remove oxygen, catalytic hydrodeoxygenation (HDO) reactions are carried out. Monometallic Mo/Si, Pt/Si as well as bimetallic PtMo/Si catalysts were prepared and evaluated in the hydrodeoxygenation (HDO)reaction of dibenzofurane (DBF) as a model molecule in biomass derived bio-oil.Universidad de Málaga.

Control and prevention of antibiotic residues and contaminants in sheep and goat s milk

[EN] The use of veterinary drugs to treat mastitis and other pathologies in dairy sheep and goats is a usualpractice in current production systems. The risk of antibiotic residues in milk on farms is high if goodfarming practices are not applied, in this sense control measures must be implemented to prevent drugresidues from entering the food chain. Moreover there are other compounds that may contaminate milkvia the environment, water or animal feed, such as mycotoxins that are one of the most harmful contam-inants given their negative effects on consumer health. This work presents the problems that arise whenresidues and contaminants are present in sheep and goat s milk. It also addresses the causes and theconsequences of their presence, and the main measures of prevention and control required to guaranteemilk that is safe for consumers and of high quality for the dairy industry.Berruga Fernandez, MI.; Molina Casanova, AM.; Althaus, RL.; Molina Pons, MP.

Transcriptional Elongation and mRNA Export Are Coregulated Processes

Chromatin structure complexity requires the interaction and coordinated work of a multiplicity of factors at different transcriptional regulation stages. Transcription control comprises a set of processes that ensures proper balance in the gene expression under different conditions, such as signals, metabolic states, or development. We could frame those steps from epigenetic marks to mRNA stability to support the holistic view of a fine-tune balance of final mRNA levels through mRNA transcription, export, stability, translation, and degradation. Transport of mRNA from the nucleus to the cytoplasm is a key process in regulated gene expression. Transcriptional elongation and mRNA export are coregulated steps that determine the mature mRNA levels in the cytoplasm. In this paper, recent insights into the coordination of these processes in eukaryotes will be summarised

Los emojis en la comunicación digital de las marcas de bebidas: Tendencias en el social business.

A medida que las redes sociales han ido creciendo y el número de caracteres por mensaje se ha limitado, los emojis han aumentado su presencia y se han convertido en un factor clave en la comunicación de los servicios de mensajería y en las conversaciones online. La actual adopción de los consumidores por este tipo de lenguaje visual está condicionada por las propias características de los emojis. Una de las más relevantes es la facilidad de expresar ciertas emociones y sentimientos cuyos significados permiten ser comprendidos a nivel global independientemente de la cultura, idioma o experiencia. El empleo de los emojis en los mensajes de los usuarios en redes sociales no se trata de un fenómeno aislado, sino que actualmente también se ha introducido en el mundo empresarial. Las primeras marcas que están creando tendencia en este ámbito provienen del sector de bebidas. Las principales razones por las que estas marcas hacen uso de los emojis como elemento estratégico de sus comunicaciones en Twitter son: (1) Las marcas tienen un espacio limitado para transmitir sus contenidos: (2) Impulsar acciones en redes sociales tales como Social Business; (3) Originalidad del discurso corporativo para incentivar un diálogo atractivo al usuario; (4) Generar engagement o cercanía con tus usuarios; (5) Indicadores para la planificación de las campañas publicitarias en Twitter. La integración de los emojis dentro del discurso de las marcas debe estar alineada y ser coherente con la identidad y valores de éstas. Estos emojis contribuyen a contrarrestar los mensajes negativos frente a situaciones de reclamaciones de usuarios a las marcas e incluso generando, en situaciones de descontento, un cambio de percepción favorable hacia la marca. Estas acciones con los emojis contribuyen a generar emociones positivas que impactan en la reputación corporativa.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Aflatoxin M1 in the intermediate dairy products from Manchego cheese production: distribution and stability

[EN] Aflatoxin M1 (AFM1 ) distribution in curd, whey, Manchego cheese, the traditional Spanish whey cheese Requesón and Requesón whey, and its stability during two different cold treatments, have been studied. Raw ewe¿s milk was artificially contaminated with AFM1 in a final concentration of 50 and 100 ng kg-1, and was used to produce Manchego cheese. AFM1 determinations were carried out by HPLC with fluorimetric detection after immunoaffinity clean-up. The mean AFM1 concentrations in the produced curd and Manchego cheese were approximately 2- and 3-fold higher than the initial milk they were made from, and the levels of this toxin remaining in whey were 42.3 % and 51.3 % of the initial concentrations. In the Requesón samples, the mean AFM1 values were 1.7 times higher than those in the corresponding whey, while 33.7 % and 44.4 % of the AFM1 concentration detected in milk also appeared in the Requesón whey. Short refrigeration and freezing periods did not affect the toxin levels in either curd or Requesón samples. When ewe¿s milk destined for Manchego cheese-making is AFM1 -contaminated at the EU limit level (50 ng kg-1) or double, a concentration of this toxin will appear in the manufactured products, but values will be considerably below the toxic doses (Tolerable Daily Intake = 2 ng kg-1 body weight per day), which poses a human health problem.Rubio, R.; Moya Salvador, VJ.; Berruga Fernandez, MI.; Molina Pons, MP.; Molina Casanova, A.

Analysis of the perception of conflict and its positive resolution in university students

This research aimed to analyze the perception of conflict in universities and the ways of dealing with it in relation to the 17 Sustainable Development Goals of the United Nations. The research was developed from a quantitative approach in three universities in two European countries: the University of Murcia and Complutense University of Madrid (Spain) and University of Minho (Portugal). The sample consisted of 247 university students and the technique used was an ad hoc survey administered online. Among the main research results we can highlight that (a) the perception of conflict is mostly negative; (b) there are predictive variables in the positive view of conflict; and (c) university students clearly identify the peaceful resolution of conflicts with some of the Sustainable Development Goals. The main conclusions are that conflict is inherent to any organization and the university must be sensitive to the conflicts that occur within it. It is therefore necessary to create intra-university mediation services as a conflict resolution resource for the entire university community. Training and a positive view of conflict favors the construction of a citizenry capable of dialogue and of resolving the conflicts that arise in their adult life.This research work is the result of the Eramus+ LIMEdiat− Licence Européenne en Médiation pour l’Inclusion Sociale (European Degree in Mediation for Social Inclusion) project -2020-1-FR01-KA203-079934, with the participation of the University of Minho (Portugal), the University of Murcia (Spain), Conservatoire National des Arts et Métiers (CNAM) (France), and the Universitat Degli Studi di Cagliari (Italy). The total budget of the research project was 304,066 €
