Intercultural citizenship education in the English language classroom in higher education: Does it lead to language learning?

This paper reports a bilateral university project in the foreign language classroom designed to promote intercultural competence, language development and active and responsible citizenship through content-language integrated learning (CLIL). The rationale for broadening the scope of language courses and combining them with intercultural citizenship or human rights education rests on the idea that language teaching has instrumental (linguistic-oriented and communicative) purposes as well as educational purposes (development of critical thinking skills, development of the self and of the citizenship dimension) (Byram, 2014). Pedagogic proposals (Porto, 2015) and empirical studies reporting on classroom practice are recently available (Byram, Golubeva, Han & Wagner, 2016; Porto, 2014; Porto & Byram, 2015b). These studies have connected both types of education (language and citizenship/human rights) and have demonstrated growth in self/intercultural awareness, criticality and social justice responsibility, as well as the emergence of a sense of community among students during the projects. However, the concern remains as to whether this combination leads to language learning and this article addresses this issue.Instituto de Investigaciones en Humanidades y Ciencias Sociale

A prática pedagógica: uma oportunidade de ressignificar o conflito interpessoal em ensino fundamenta

This article seeks to present the training experience of practicing teachers in the framework of the pedagogical practice conducted in the last year of the bachelor’s degree in Elementary Basic Education. The pedagogical practice implied an investigative exercise that allowed an approach to the understanding of the interpersonal conflict from the voices of the children of two official educational institutions of the Municipality of Medellín, this experience contributed to the resignification of the teaching profession of the teachers in exercise and the reflection of the place of the pedagogical practice in the formation of teachers.Este artículo de investigación busca dar a conocer la experiencia de formación de maestros en ejercicio en el marco de la práctica pedagógica realizada en el último trayecto de la Licenciatura en Educación Básica Primaria.

Evaluation of the presence of genes FLO1, FLO5, FLO9 and FLO11 in Saccharomyces cerevisiae strains

ABSTRACT: Since cell-cell attachment enables biomass separation from the fermentation product, flocculant ability of Saccharomyces cerevisiae strains is a relevant characteristic for the ethanol industry, as it reduces operating times and costs. The capacity of S. cerevisiae to adhere to cells and abiotic surfaces is conferred by a specific group of cell wall proteins called adhesions, which are encoded by FLO gene family. The expression of these genes is associated to the response to some stress conditions that are common to both natural environments and industrial fermentations. This study evaluates the presence of genes FLO1, FLO5, FLO9 and FLO11 in S. cerevisiae strains, isolated from natural environments, and in turn, it demonstrates the importance of the identification of FLO genes in native strains for adequate control of flocculation in industrial fermentations.RESUMEN: La capacidad floculante en cepas de Saccharomyces cerevisiae es una característica importante para la industria del etanol ya que la unión célula-célula permite la fácil separación de la biomasa del producto de fermentación, reduciendo el tiempo y los costos operacionales. La capacidad que tiene S. cerevisiae para adherirse a células y superficies abióticas es conferida por un grupo específico de proteínas de la pared celular, denominadas adhesinas y codificadas por la familia de genes FLO. La expresión de dichos genes está relacionada con la respuesta a algunas condiciones de estrés que son comunes tanto a ambientes naturales como a fermentaciones industriales. Este estudio evaluó la presencia de los genes FLO1, FLO5, FLO9 y FLO11 en cepas de S. cerevisiae, aisladas de ambientes naturales, y a su vez, evidenció la importancia de la identificación de los genes FLO en cepas nativas para un control adecuado de la floculación en fermentaciones industriales

Síntesis de nanopartículas de plata usando como agente reductor extracto de epazote: Efecto antimicrobial en el fruto del annono

La preservación de frutas y hortalizas desde su cosecha hasta su comercialización es importante tanto sanitariamente, como comercialmente. Se reportan los resultados de un ensayo de exposición del fruto annona durante 25 días a temperatura ambiente mediante dos alternativas: a) la annona con envoltura impregnada con nanoparticulas de plata obtenidas a partir de nitrato de plata y extracto de epazote y b) la annona sin ninguna protección. Se evaluó mediante seguimiento diario. Al finalizar la experiencia, las muestras fueron abiertas para evaluar visualmente el avance del deterioro desde la cáscara hacia el corazón de la fruta. Los mejores resultados se obtuvieron con el tratamiento de la envoltura con las nanoparticulas. La annona sin envoltura con nanopartículas, como era de esperar, mostró el mayor grado de deterioro. Se probó su actividad antimicrobiana de las nanopartículas con el fruto de nombre annona, que se cultivan, específicamente en el municipio de Chietla, Puebla.The preservation of fruits and vegetables from harvest to commercialization is important both sanitary, and commercially. the results of a test exposure result Annona reported for 25 days at room temperature by two alternatives: a) the Annona enveloped with silver nanoparticles obtained from silver nitrate and extract wormseed b) the Annona unprotected. It was assessed by daily monitoring. After the experience, the samples were opened to visually evaluate the progress of deterioration from the skin to the heart of the fruit. The best results were obtained with the treatment of the wrapper with the nanoparticles. The annona nonenveloped with nanoparticles, as expected, showed the highest degree of impairment. antimicrobial activity of the nanoparticles was tested with the fruit of Annona name, grown, specifically in the municipality of Chietla, Puebla

Reducción de metales con extractos vegetales: una alternativa en la recuperación de metales

Como resultado de diferentes actividades humanas, muchos metales acaban disueltos en las aguas, cuando sus concentraciones son más elevadas de lo normal y producen efectos nocivos pasan a ser considerados contaminantes. De esta manera, es primordial su eliminación, o al menos, una disminución de su impacto. En este trabajo se reportan los resultados obtenidos de la reducción de metales, cobre, plata y zinc, utilizando los extractos vegetales de la Hoja de rosa, Hierbabuena (Mentha piperita) y Ruda (Ruta graveolens). Se comprobó el poder reductor de los extractos a través de la formación de nanopartículas de plata y cobre, monitorización mediante el uso de espectros UV-Vis. Se logró recuperar la plata en forma de solido limpio y brillante con buenos rendimientos. Se realizo la identificación cualitativa de la presencia de flavonoides, ácidos fenólicos los cuales son metabolitos secundarios de muchas plantas, y juegan un papel fundamental su la actividad antioxidante.As a result of different human activities, many metals end up dissolved in the waters, when their concentrations are higher than normal and produce harmful effects become pollutants. In this way, it is essential to eliminate them, or at least to reduce their impact. In this work the results obtained from the reduction of metals, copper, silver and zinc are reported, using the vegetal extracts of the Rose Leaf, Hierbabuena (Mentha piperita) and Ruda (Ruta graveolens). The reducing power of the extracts was checked through the formation of silver and copper nanoparticles, monitoring by the use of UV-Vis spectra. lt was possible to recover the silver in the form of clean and bright salid with good yields. Qualitative identification was made of the presence of flavonoids, phenolic acids which are secondary metabolites of many plants, and their antioxidant activity plays a fundamental role

Nurse-Led Interventions in Chronic Obstructive Pulmonary Disease Patients: A Systematic Review and Meta-Analysis

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, causing 3.32 million deaths in 2019. COPD management has increasingly become a major component of general and hospital practice and has led to a different model of care. Nurse-led interventions have shown beneficial effects on COPD patient satisfaction and clinical outcomes. This systematic review was conducted to identify and assess nurse-led interventions in COPD patients in terms of mental, physical, and clinical status. The review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. The relevance of each manuscript was assessed according to the inclusion criteria, and we retrieved full texts, as required, to reach our conclusions. Data extraction was performed independently by two reviewers, and the risk of bias was assessed using the Cochrane Risk of Bias tool. Forty-eight articles were included in the analysis, which focused on the management of COPD patients by hospital, respiratory and primary nursing care. Nursing management was shown to be highly effective in improving quality of life, emotional state, and pulmonary and physical capacity in COPD patients. In comparison, hospital and respiratory nurses carried out interventions with higher levels of effectiveness than community nurses

Didactic Proposal with Ecological and Interdisciplinary Approach: a Commitment to Inclusive Higher Education

People with intellectual disabilities have had few opportunities to access higher education, for a long time it has been considered that they are not a potential group to be trained in the university environment. This article is derived from an investigation that was developed in the Colombian context, the purpose of which was to contribute to reducing the barriers of young people for their inclusion in the family, social, academic and occupational context, through the design and validation of a model of comprehensive care with an ecological and interdisciplinary approach. The study had a mixed methodological perspective, the ABAS II scale was used to evaluate the adaptive behavior index in 20 young people as a pretest and posttest. It was concluded that this experience contributed to the formation and quality of life of the young people; and it showed that all people can be taught, but that each one learns in their uniqueness.Las personas en situación de discapacidad intelectual han tenido pocas oportunidades para acceder a la educación superior; durante mucho tiempo se ha considerado que ellas no son un colectivo potencial para formarse en el ámbito universitario. Este artículo es derivado de una investigación que se desarrolló en el contexto colombiano, cuyo propósito consistió en contribuir a disminuir las barreras de los jóvenes para su inclusión en el contexto familiar, social, académico y ocupacional, mediante el diseño y validación de un modelo de atención integral con enfoque ecológico e interdisciplinar. El estudio tuvo una perspectiva metodológica mixta, se utilizó la escala ABAS II para evaluar el índice de conducta adaptativa en 20 jóvenes a modo de pretest y postest. Se concluyó que esta experiencia contribuyó a la formación y calidad de vida de los jóvenes; y mostró que a todas las personas se les puede enseñar, pero que cada una aprende en su singularidad

Clinical validation of risk scoring systems to predict risk of delayed bleeding after EMR of large colorectal lesions

[Background and Aims]: The Endoscopic Resection Group of the Spanish Society of Endoscopy (GSEED-RE) model and the Australian Colonic Endoscopic Resection (ACER) model were proposed to predict delayed bleeding (DB) after EMR of large superficial colorectal lesions, but neither has been validated. We validated and updated these models.[Methods]: A multicenter cohort study was performed in patients with nonpedunculated lesions ≥20 mm removed by EMR. We assessed the discrimination and calibration of the GSEED-RE and ACER models. Difficulty performing EMR was subjectively categorized as low, medium, or high. We created a new model, including factors associated with DB in 3 cohort studies.[Results]: DB occurred in 45 of 1034 EMRs (4.5%); it was associated with proximal location (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.31-6.16), antiplatelet agents (OR, 2.51; 95% CI, .99-6.34) or anticoagulants (OR, 4.54; 95% CI, 2.14-9.63), difficulty of EMR (OR, 3.23; 95% CI, 1.41-7.40), and comorbidity (OR, 2.11; 95% CI, .99-4.47). The GSEED-RE and ACER models did not accurately predict DB. Re-estimation and recalibration yielded acceptable results (GSEED-RE area under the curve [AUC], .64 [95% CI, .54-.74]; ACER AUC, .65 [95% CI, .57-.73]). We used lesion size, proximal location, comorbidity, and antiplatelet or anticoagulant therapy to generate a new model, the GSEED-RE2, which achieved higher AUC values (.69-.73; 95% CI, .59-.80) and exhibited lower susceptibility to changes among datasets.[Conclusions]: The updated GSEED-RE and ACER models achieved acceptable prediction levels of DB. The GSEED-RE2 model may achieve better prediction results and could be used to guide the management of patients after validation by other external groups.

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed

La Comisión de la Verdad en Colombia: conocimiento, percepción, eficacia y emociones asociadas

La Comisión de la Verdad en Colombia se estableció a partir del modelo de justicia transicional. Su función es servir como medida de reconocimiento de los hechos violentos durante el conflicto armado, que han dejado más de nueve millones de víctimas. En este marco, se realizó un estudio descriptivo correlacional (N=1166) con una muestra de 22 departamentos del país para evaluar el conocimiento, la aprobación y la efectividad percibida de los primeros años de la Comisión a partir de aspectos psicosociales: victimización, emociones colectivas, reconciliación, memoria colectiva. El 58% eran víctimas directas. Los resultados indican altos niveles de aprobación y de disposición a participar en las actividades de la Comisión, así como cierto escepticismo sobre su utilidad y una baja confianza en las disculpas oficiales de los grupos en conflicto. También se encuentra un alto índice de emociones positivas relacionadas con la comisión y una baja confianza en las instituciones gubernamentales. Lo encontrado en este estudio, coincide con experiencias previas de comisiones de la verdad en Latinoamérica, y abre el debate sobre las especificidades del contexto colombiano en la búsqueda de paz y las implicaciones del trabajo de la comisión en el proceso de reparación
