La importancia de la formación inicial docente y su gestión para el acceso al mundo laboral.

Nowadays, as future teachers, we wonder about the training which we will get our job in the future and if this will be enough to teach a correct education for our students. From Spain's enquiry position in reports' PISA, we consider relevant as a study about the formation and quality of the selection of new teachers in our country as the educational objectives, since this shortage education and correct administration of the future teachers has become one of the less valued in our country even though being of the most important for our society.  Starting from these weaknesses, we have considered some methods and propose that, in our opinion, will improve our teacher education programs. After reading some articles and consulting many investigations we have written some possible solutions that we consider effective to get an educational quality in a future and achieving a major respect for this profession in Spain.  A día de hoy, como futuras docentes, nos hacemos preguntas sobre la formación con la que, en un futuro, entraremos en nuestros puestos de trabajo y si esta será suficiente para transmitir un correcto aprendizaje a nuestros alumnos. A partir de la consulta de la posición de España en los informes PISA, consideramos relevante un estudio acerca de la formación y calidad de la selección del profesorado de nuevo acceso en nuestro país así como los objetivos educativos, ya que, a partir de esta escasa formación y correcta administración de los futuros profesores, esta profesión se ha convertido en una de las menos valoradas en nuestro país, aun siendo de las más importantes para nuestra sociedad.  Partiendo de estos puntos flacos, hemos considerado algunos métodos y propuestas que, a nuestro parecer, mejorarían nuestros programas de formación docente. Tras la lectura de diversos artículos y la consulta de numerosas investigaciones hemos llegado a la redacción de las posibles soluciones que consideramos eficaces para alcanzar una calidad educativa en un futuro e intentar conseguir en España un mayor respeto para esta profesión

Applying Neural Networks to Hyperspectral and Multispectral Field Data for Discrimination of Cruciferous Weeds in Winter Crops

In the context of detection of weeds in crops for site-specific weed control, on-ground spectral reflectance measurements are the first step to determine the potential of remote spectral data to classify weeds and crops. Field studies were conducted for four years at different locations in Spain. We aimed to distinguish cruciferous weeds in wheat and broad bean crops, using hyperspectral and multispectral readings in the visible and near-infrared spectrum. To identify differences in reflectance between cruciferous weeds, we applied three classification methods: stepwise discriminant (STEPDISC) analysis and two neural networks, specifically, multilayer perceptron (MLP) and radial basis function (RBF). Hyperspectral and multispectral signatures of cruciferous weeds, and wheat and broad bean crops can be classified using STEPDISC analysis, and MLP and RBF neural networks with different success, being the MLP model the most accurate with 100%, or higher than 98.1%, of classification performance for all the years. Classification accuracy from hyperspectral signatures was similar to that from multispectral and spectral indices, suggesting that little advantage would be obtained by using more expensive airborne hyperspectral imagery. Therefore, for next investigations, we recommend using multispectral remote imagery to explore whether they can potentially discriminate these weeds and crops

Vaginal isolation of beta-haemolytic Streptococcus from bitches with and without neonatal deaths in the litters

The aim of the study was to identify beta-haemolytic streptococci in the vagina of bitches who had delivered healthy litters and bitches who had delivered litters in which neonatal deaths occurred. Fifty-one bitches divided into two groups were used. Group 1 (G1) included 28 bitches that had delivered healthy litters and group 2 (G2) included 23 bitches that had delivered puppies who died in the neonatal period. Two vaginal samples were taken, one in proestrus and the other at the end of gestation (EG). Beta-haemolytic Streptococcus (BS) was isolated from 16 bitches (57%) in G1 and from 21 bitches (91%) in G2. The bacteriological cultures, serological tests (Streptex®) and PCR assay allowed identification of Streptococcus canis and Streptococcus dysgalactiae in G1 and G2. Ultramicroscopic studies allowed the observation of M Protein and capsules in strains of S. dysgalactiae and S. canis in G1 and G2. The S. canis strains isolated from G2 showed thicker capsules than S. canis strains isolated from G1 (234 ± 24.2 vs 151.23 ± 28.93 nm; p < .001.). No differences were observed in capsule thickness between strains of S. dysgalactiae isolated from G1 and G2 (210 ± 13.54 vs 211.66 ± 19.67 nm; p > .70). All strains of beta-haemolytic Streptococcus isolated were penicillin sensitive. Penicillin was administered from EG to 5 days post-partum in 10 G2 females with isolation of BS (G2A). Saline solution was administered in eleven G2 females with isolation of BS (G2B). Ninety per cent of the puppies survived in G2A and 25% survived in G2B. Our results suggest BS is involved in canine neonatal deaths.Facultad de Ciencias Veterinaria

Autonomic nervous system measurement in hyperbaric environments using ECG and PPG signals

The main aim of this work was to characterise the Autonomic Nervous System (ANS) response in hyper- baric environments using electrocardiogram (ECG) and pulse- photoplethysmogram (PPG) signals. To that end, 26 subjects were introduced into a hyperbaric chamber and five stages with different atmospheric pressures (1 atm; descent to 3 and 5 atm; ascent to 3 and 1 atm) were recorded. Respiratory information was extracted from the ECG and PPG signals and a combined respiratory rate was studied. This information was also used to analyse Heart Rate Variability (HRV) and Pulse Rate Variability (PRV). The database was cleaned by eliminating those cases where the respiratory rate dropped into the low frequency band (LF: 0.04-0.15 Hz) and those in which there was a discrepancy between the respiratory rates estimated using the ECG and PPG signals. Classical temporal and frequency indices were calculated in such cases. The ECG results showed a time-related depen- dency, with the heart rate and sympathetic markers (normalised power in LF and LF/HF ratio) decreasing as more time was spent inside the hyperbaric environment. A dependency between the atmospheric pressure and the parasympathetic response, as reflected in the high frequency band power (HF: 0.15-0.40 Hz), was also found, with power increasing with atmospheric pressure. The combined respiratory rate also reached a maximum in the deepest stage, thus highlighting a significant difference between this stage and the first one. The PPG data gave similar findings and also allowed the oxygen saturation to be computed, therefore we propose the use of this signal for future studies in hyperbaric environments

Un estudio interuniversitario sobre la importancia de la redefinición del problema en un contexto de intervención familiar

ABSTRACTThis article describes the results and conclusions of a study developed by the Institute of Family Sciences of Los Andes University (Santiago de Chile), and Education Faculty of the National University of Distance Education (Spain), on the “Redefinition” technique used in conflict-resolution mediation as the basis to achieve agreement. This study analyzes the problem definition sequence unfolded by the parties involved in mediation, the problem redefinitions articulated by mediators, and how this affects the process. The sample analysis indicates that it is the definitions of objectives done by the party and the redefinition of these done by the mediator that are more important than definition and redefinition of the problems. Focusing the mediation process on the objectives to be achieved rather than on the problems that caused the conflict would help to diminish an adverse climate, and strengthen the central role of the parties involved. Additionally, the research offers other possibilities in the use of techniques such as the incorporation of empowering, legitimation and recognition elements in the redefinitions, once they have been accepted by the parties involved. In this manner, a new field of research on mediation is opened as the study recognises a new technique of intervention used in the research process. This technique has been provisionally named “recognition anchorage”, when the mediator repeats back verbatim to one participant what the other has just recognised or acknowledged.RESUMENEn el presente articulo se exponen los resultados y conclusiones de un estudio interuniversitario realizado por el Instituto de Ciencias de la Familia de la Universidad de los Andes (Santiago de Chile), junto con la Facultad de Educación de la Universidad Nacional de Educación a Distancia (España), sobre la técnica de la “Redefinición” del problema en mediación, como base para lograr el acuerdo. Este estudio analiza la secuencia de definición de problemas desplegados por las partes en la mediación, las redefiniciones que de éstos hace el mediador y el efecto que esto produce en el proceso. El análisis de la muestra señalaría que tanto o más importante que la definición y redefinición de los problemas, es la definición de objetivos que hace la parte, y la redefinición de los mismos que hacen los mediadores. Centrar las intervenciones de la mediación más en los objetivos que en los problemas, ayudaría a disminuir el clima adverso y fortalecería el protagonismo de las partes. El resultado del trabajo de investigación aporta, además, otras posibilidades en el uso de técnicas como la incorporación de “empowerments”, legitimaciones y reconocimientos, en las redefiniciones, cuando aquellos han sido aceptados por las partes. De igual manera, se abre una nueva vía de investigación al reconocerse una nueva técnica o intervención utilizada en el proceso de la investigación; a dicha técnica se le ha denominado provisionalmente “anclaje de reconocimiento”, que consiste en la repetición textual realizada por los mediadores, del reconocimiento realizado por uno de los participantes al otro.ABSTRACTThis article describes the results and conclusions of a study developed by the Institute of Family Sciences of Los Andes University (Santiago de Chile), and Education Faculty of the National University of Distance Education (Spain), on the “Redefinition” technique used inconflict-resolution mediation as the basis to achieve agreement.

El impacto de la obesidad sobre el lipidoma cardíaco y sus consecuencias en el daño cardíaco en ratas obesas

To explore the impact of obesity on the cardiac lipid profile in rats with diet-induced obesity, as well as to evaluate whether or not the specific changes in lipid species are associated with cardiac fibrosis. Methods: Male Wistar rats were fed either a high-fat diet (HFD, 35% fat) or standard diet (3.5% fat) for 6 weeks. Cardiac lipids were analyzed using by liquid chromatography-tandem mass spectrometry. Results: HFD rats showed cardiac fibrosis and enhanced levels of cardiac superoxide anion (O 2 ), HOMA index, adiposity, and plasma leptin, as well as a reduction in those of cardiac glucose transporter (GLUT 4), compared with control animals. Cardiac lipid profile analysis showed a significant increase in triglycerides, especially those enriched with palmitic, stearic, and arachidonic acid. An increase in levels of diacylglycerol (DAG) was also observed. No changes in cardiac levels of diacyl phosphatidylcholine, or even a reduction in total levels of diacyl phosphatidylethanolamine, diacyl phosphatidylinositol, and sphingomyelins (SM) was observed in HFD, as compared with control animals. After adjustment for other variables (oxidative stress, HOMA, cardiac hypertrophy), total levels of DAG were independent predictors of cardiac fibrosis while the levels of total SM were independent predictors of the cardiac levels of GLUT 4. Conclusions: These data suggest that obesity has a significant impact on cardiac lipid composition, although it does not modulate the different species in a similar manner. Nonetheless, these changes are likely to participate in the cardiac damage in the context of obesity, since total DAG levels can facilitate the development of cardiac fibrosis, and SM levels predict GLUT4 levelsThis work was supported by funds from the Sociedad Española de Arteriosclerosis (Basic Research Award 2015), from Plan Estatal I+D+I 2013-2016: PI15/01060 and SAF2016-81063.

Medicago sativa L.: mejora y nuevos aspectos de su valor nutritivo y funcional por co-inoculación bacteriana

Objective: to study the effect of co-inoculation with Ensifer meliloti and Halomonas maura of the leguminous Medicago sativa L., on growth, nutritional and functional value, grown under salinity conditions. Methods: plants of M. sativa were grown in a solution with a mixture of salts (CaSO4, MgCl, NaCl and NaHCO 3) and were co-inoculated with its specific rhizobium and the halophilic moderated bacterium H. maura. Different physiologic parameters were determined, as well as, nitrogen and minerals content. Furthermore, an assay of in vitro digestibility was carried out. Results: salinity had a negative effect on the plants; however, co-inoculation increased yield, nitrogen content, total minerals, Ca and Mg. Moreover, physiologic parameters as water potential and leghemoglobin content in fresh nodules were higher compared to those of plants inoculated only with E. meliloti. Both, salinity and bacterial treatment with E. meliloti and H. maura increased the antioxidant capacity of the legume, in dialyzates and retentates collected after an in vitro digestibility assay. Conclusion: co-inoculation of plants with E. meliloti and H. maura could improve the alfalfa yield under specific salinity conditions, increasing the nutritional and functional value of the plants. M. sativa could be considered in the formulations of nutritional supplements for the human diet.Este trabajo forma parte de la Tesis Doctoral de Rosario Martínez y ha sido financiado por European Regional Development Fund (ERDF) y cofinanciado por los proyectos P07-AGR-2704 y RNM-4746 de la Junta de Andalucía (España).

MOOC como herramienta para el aprendizaje de contenidos específicos en el área de la Fisiología

Teniendo en cuenta que el aprendizaje integral y la implementación de las TICs están cada vez más integradas en el sistema educativo, la creación de “cápsulas educativas”-MOOCs son una herramienta creativa que puede ayudar al alumnado en la asimilación de los conocimientos. Además, al ser una herramienta de duración corta les obliga resumir la información, destacar la más importante y ser capaces de trasmitirla. Para ello, el objetivo principal de esta propuesta de innovación docente ha sido elaborar una nueva herramienta docente y aplicarla en el área de Fisiología, en concreto en la asignatura de Fisiología Celular y Humana del Grado en Farmacia. Para ello se formaron diferentes grupos de estudiantes a los que les asignó una temática relacionada con el área de Fisiología y dos tutores (participantes en el equipo de investigación) que los han acompañado en la creación de MOOC. Por otro lado, se creó el grupo de evaluadores externos, responsables para la evaluación de la capsula educativa definitiva. Para facilitar el desarrollo del proyecto, antes del comienzo del proyecto se elaboraron y se consensuaron las rúbricas necesarias para evaluar el proceso de la creación de MOOC por parte de los tutores y evaluadores. La comunicación entre los grupos de estudiantes y de los miembros del equipo de investigación se ha realizado usando el correo electrónico y con documentos compartidos en la nube de la UGR. Las diferentes tutorías entre los tutores asignados y los grupos de los alumnos, se han realizado por Google Meet. La nota final de las capsulas educativas, ha sido resultado de la interacción tanto del equipo de tutores como de evaluadores externos. Al final del proceso se ha hecho una exposición de las capsulas educativas en la clase con los demás compañeros. Al finalizar el proceso, se ha utilizado la plataforma de Google Forms para recibir las opiniones de los estudiantes y recoger sus propuestas. Según las opiniones manifestadas, la iniciativa de aplicar esta herramienta en el área de Fisiología ha recibido muy buenas críticas sobre todo sobre la innovación de la propuesta. El alumnado por otro lado destacó que le gustaría encontrar esta herramienta en otras asignaturas. Sin embargo, también mencionaron que les gustaría saber algo más sobre aplicaciones disponibles para elaborar los videos y poder ser aún más creativos. Por último, se usará la plataforma zenodo para la difusión y divulgación de los trabajos creados para que los demás estudiantes puedan consultarlos. Los resultados de esta propuesta se publicarán en congresos docentes nacionales e internacionales con el objetivo de compartir la experiencia con otros docentes e intentar implementar esta herramienta en asignaturas de áreas afines.Considering that comprehensive learning and the implementation of ICTs are increasingly integrated into the educational system, the creation of "educational capsules"-MOOCs are a creative tool that can help students assimilate knowledge. In addition, having a limited duration forces them to summarize the information, highlight the most important and be able to transmit it. For this, the main objective of this teaching proposal was the development of a new teaching tool and apply it in Physiology, specifically in the subject of Cellular and Human Physiology of the Degree in Pharmacy. For this, different groups of students were formed and a specific subject was assigned to them, related to the area of Physiology. Moreover, two tutors (member of the research team) were assigned to each group and have accompanied them in the creation of MOOCs. On the other hand, the group of external evaluators, responsible for the evaluation of the educational capsule, was created. To facilitate the development of the project, prior to the beginning of the project, the necessary rubrics were prepared and discussed between the different members, to be able to evaluate the process of creating MOOCs by both the tutors and evaluators. Communication between the student groups and the members of the research team was maintained using emails and documents were shared in the UGR cloud. The meetings between the assigned tutors and the student groups have been carried out through Google Meet. The grade of the educational capsules has resulted as the median of tutors as well the external evaluators. Once created, MOOCs were presented in the rest of the classroom with the other classmates. At the end of the process, the Google Forms platform has been used to fulfil a questionnaire and collect the opinions of the students and collect their proposals for future improvements. According to the opinions expressed, the initiative to apply this tool in the Physiology area has received very good reviews by the students, especially regarding the innovation of the proposal. The students, on the other hand, highlighted that they would like to be able to use this tool in other subjects of their carreer. However, they also mentioned that they would like to know more about available applications to make videos, a fact that would help them be even more creative. Finally, the zenodo platform will be used for the dissemination of the works created so that other students can consult them. The results of this proposal will be published in national and international teaching conferences with the aim of sharing the experience with other teachers and trying to implement this tool in subjects in related areas.Universidad de Granad

Interventions in health organisations to reduce the impact of adverse events in second and third victims

Background Adverse events (AE) are also the cause of suffering in health professionals involved. This study was designed to identify and analyse organization-level strategies adopted in both primary care and hospitals in Spain to address the impact of serious AE on second and third victims. Methods A cross-sectional study was conducted in healthcare organizations assessing: safety culture; health organization crisis management plans for serious AE; actions planned to ensure transparency in communication with patients (and relatives) who experience an AE; support for second victims; and protective measures to safeguard the institution’s reputation (the third victim). Results A total of 406 managers and patient safety coordinators replied to the survey. Deficient provision of support for second victims was acknowledged by 71 and 61 % of the participants from hospitals and primary care respectively; these respondents reported there was no support protocol for second victims in place in their organizations. Regarding third victim initiatives, 35 % of hospital and 43 % of primary care professionals indicated no crisis management plan for serious AE existed in their organization, and in the case of primary care, there was no crisis committee in 34 % of cases. The degree of implementation of second and third victim support interventions was perceived to be greater in hospitals (mean 14.1, SD 3.5) than in primary care (mean 11.8, SD 3.1) (p?<?0.001). Conclusions Many Spanish health organizations do not have a second and third victim support or a crisis management plan in place to respond to serious AEs
