Del hogar estudiantil a la Facultad de Ciencias

Bibliografía: p. 223-227En 1959 los arquitectos Justino Serralta y Carlos Clémot ganan el concurso de anteproyectos para el Hogar Estudiantil Universitario de Montevideo. Este alojamiento para estudiantes, formaba parte de un plan más amplio para una Ciudad Universitaria que incluía equipamiento deportivo y servicios comunes en la zona de Malvín Norte. El proyecto ganador del concurso a dos grados sufre ajustes y recortes hasta la interrupción de las obras en el año 1971, quedando su esqueleto de hormigón armado abandonado por más de dos décadas. Para fines de la década del 90 la estructura es recuperada para alojar a la Facultad de Ciencias y en 2016 es rehabilitado el gimnasio como anexo del Instituto Superior de Educación Física. Esta investigación pretende lograr un conocimiento detallado de los proyectos arquitectónicos desarrollados para el Hogar Estudiantil enmarcados en las circunstancias y preocupaciones disciplinares que los condicionaron e incidieron en su definición y materialización. Estos proyectos superpuestos en un mismo sitio y estructura edilicia dan cuenta de la situación de la arquitectura y la coyuntura política y universitaria del Uruguay en el momento histórico en que fueron realizadosINTRODUCCIÓN: Justificación y relevancia de la investigación -- Antecedentes y marco teórico -- Objetivos -- Metodología y fuentes -- Estructura y contenidos -- EL CONCURSO 1959: Contexto previo -- Primer grado: concurso de ideas -- Segundo grado: anteproyecto -- Proyecto ejecutivo -- LA CONSTRUCCIÓN: EL ABANDONO 1971 -- Contexto histórico: la Udelar -- La construcción: el recorte durante la intervención -- El esqueleto abandonado -- LA FACULTAD DE CIENCIAS: Contexto histórico -- El proyecto -- 2016: una experiencia en el Hogar Estudiantil -- CONCLUSIONES -- ANEXO: Listado de plano

From initial teacher training to the teaching of social knowledge of elementary beginnings teachers: a relationship to build

El artículo plantea la discusión sobre la formación inicial de profesores generalistas y su relación con las prácticas de enseñanza de las ciencias sociales, desplegadas por profesores noveles en la educación básica primaria. Esta discusión se hace a partir de los resultados de una investigación en la que se analizan dos casos que corresponden a profesoras principiantes vinculadas laboralmente a instituciones educativas públicas colombianas. Se interpretan las relaciones existentes entre los propósitos que guían la formación en didáctica de las ciencias sociales del programa universitario cursado por las profesoras y las prácticas de enseñanza del conocimiento social que ellas desarrollan con alumnos de básica primaria. Los resultados muestran divergencias entre las finalidades propuestas por la universidad y las que expresan las profesoras, con las que se evidencian en sus prácticas. Se identifica una formación inicial que privilegia lo pedagógico sobre lo disciplinar, enfatiza en el currículo oficial basado en estándares de competencias, que instrumentaliza la enseñanza a través de proyectos y de unidades didácticas alejadas del contexto real de los estudiantes. Estos hallazgos llevan a plantear nuevamente la necesidad de avanzar hacia enfoques críticos en la formación inicial de maestros, comprometidos con la educación para la democracia y la transformación social, en los que se tenga en cuenta el conocimiento de la disciplina a enseñar y de su didáctica específica; que sean capaces de reflexionar, comprender y tomar decisiones sobre el por qué y para qué se enseña y se aprende este conocimiento en la educación primaria.The article raises the discussion on the initial training of generalist teachers and its relationship with the teaching practices of the social sciences, deployed by novice teachers in primary education. This discussion is based on the results of an investigation in which two cases are analyzed that correspond to beginning teachers working with Colombian public schools. The existing relationships between the purposes that guide the training in didactics of the social sciences of the university program taken by the teachers and the teaching practices of social knowledge that they develop with primary school students are interpreted. The results show divergences between the purposes proposed by the university and those expressed by the professors, with which they are evident in their practices. An initial teacher training is identified that privileges the pedagogical over the disciplinary, emphasizes the official curriculum based on competency standards, which instrumentalizes teaching through projects and didactic units far from the real context of the students. These findings lead to raise again the need to move towards critical approaches in the initial teacher training, committed to education for democracy and social transformation, in which the knowledge of the discipline to be taught and its didactics is taken into account specific; that they are able to reflect, understand and make decisions about why and for what this knowledge is taught and learned in primary education.peerReviewe

Polyphenolic Profile and Antioxidant Activity of Leaf Purified Hydroalcoholic Extracts from Seven Mexican Persea americana Cultivars

Persea americana (avocado) is a fruit consumed worldwide; however, since avocado leaves are apparently a natural ingredient that can be used as a traditional medicine, they can be a potential source of bioactive compounds. This study aimed to analyze the antioxidant activity of seven Mexican avocado leaf extracts by DPPH•, ABTS•+, and lipid peroxidation (LPO), and to identify the compoundprofilebyliquidchromatographycoupledtomassspectrometry/electronsprayionization. The highest free radical-scavenging activity was observed for Platano Delgado and Criollo 6 avocado cultivars havin IC50 values of 271.86 ± 13.69 and 269.56 ± 6.53 for DPPH• and ABTS•+ radicals, respectively, while the best result for lipid oxidation inhibition was registered in Criollo 6 cultivar extract. Inthisstudyfortyonecompoundsweredetectedinavocadoleavesofthethesevencultivars analyzed, and of these compounds, eighteen phenolics were identified for first time in such plant material. The present study demonstrated that Mexican cultivars of Persea americana possess diverse polyphenolic compounds with strong antioxidant activity, which might be useful in the food and pharmaceutical industries

Protagonizando el cuento en la internalización de los valores en infantes

En la práctica pedagógica el nivel de educación inicial, asume el privilegio de centrar su opción preferencial por los infantes, los cuales son motivados por sus maestras en la formación humana, el presente esbozo de investigación tuvo como finalidad determinar el efecto del programa educativo “protagonizando el cuento” en la internalización de los valores morales infantiles en niños de 5 años. Se entiende que los cuentos definidos por Martin (2006) son agentes motivadores que despiertan la curiosidad en los niños y niñas, donde lo quimérico aparece en lo real, de esta manera el niño asume protagonizar personajes, con fantasía, imaginación, originalidad e involucra promover la resolución de problemas desde su nivel de maduración. Cada cuento recrea la internalización de un valor moral que el sujeto del aprendizaje ira vivenciando y asimilando en la práctica del valor. El tipo de estudio fue aplicado, con un diseño pre experimental, método hipotético deductivo, de tipo censo, contando con 16 infantes, se utilizó la lista de cotejo que mide las dimensiones: disciplina, solidaridad, respeto mutuo y amistad. En la conclusión general se percibe que el p-valor o significancia bilateral (0,000) es menor al nivel de significancia establecido (0,05) rechazándose la hipótesis nula y aceptando la hipótesis alterna, por tanto, el programa educativo “protagonizando el cuento” mejora los valores infantiles en los niños de 5 años de una institución educativa pública

Oportunidades de aprendizaje a través de las TIC desde la perspectiva de las TAC

The vertiginous advance of technology-mediated science has had an impact in one way or another on the different sectors that frame all human activity. Research in the world describes how technology has produced important changes in the conception of teaching and learning processes. Various investigations in both Latin America and Peru have shown that the implementation of resources based on technologies is effective in the learning process. The main purpose of the study was to describe the influence of the Virtual Classroom of Social Sciences (AVCCSS) program on the academic performance of students in regular basic education. The program was based on the use of the virtual classroom developed on the Canvas platform, with the b-learning modality, it was based on the theory of constructivism, a potential complement for the classroom. We worked from the perspective of the use of information and communication technologies (ICT), mediated by Learning and Knowledge Technologies (TAC). The study is part of the positivist paradigm, quantitative approach of explanatory level, experimental design, pre-experimental subtype. The results show that the AVCCSS program and the use of the virtual classroom had a positive and significant influence on the students' academic performance.El vertiginoso avance de la ciencia mediado por las tecnologías ha repercutido en una u otra forma en los distintos sectores que enmarca toda actividad humana.

The Latin American experience of allografting patients with severe aplastic anaemia: real-world data on the impact of stem cell source and ATG administration in HLA-identical sibling transplants

We studied 298 patients with severe aplastic anaemia (SAA) allografted in four Latin American countries. The source of cells was bone marrow (BM) in 94 patients and PBSCs in 204 patients. Engraftment failed in 8.1% of recipients with no difference between BM and PBSCs (P = 0.08). Incidence of acute GvHD (aGvHD) for BM and PBSCs was 30% vs 32% (P = 0.18), and for grades III–IV was 2.6% vs 11.6% (P = 0.01). Chronic GvHD (cGvHD) between BM and PBSCs was 37% vs 59% (P = 0.002) and extensive 5% vs 23.6% (P = 0.01). OS was 74% vs 76% for BM vs PBSCs (P = 0.95). Event-free survival was superior in patients conditioned with anti-thymocyte globulin (ATG)-based regimens compared with other regimens (79% vs 61%, P = 0.001) as excessive secondary graft failure was seen with other regimens (10% vs 26%, P = 0.005) respectively. In multivariate analysis, aGvHD II–IV (hazard ratio (HR) 2.50, confidence interval (CI) 1.1–5.6, P = 0.02) and aGvHD III–IV (HR 8.3 CI 3.4–20.2, Po0.001) proved to be independent negative predictors of survival. In conclusion, BM as a source of cells and ATG-based regimens should be standard because of higher GvHD incidence with PBSCs, although the latter combining with ATG in the conditioning regimen could be an option in selected high-risk patient

The genetic ancestry of American Creole cattle inferred from uniparental and autosomal genetic markers

Cattle imported from the Iberian Peninsula spread throughout America in the early years of discovery and colonization to originate Creole breeds, which adapted to a wide diversity of environments and later received influences from other origins, including zebu cattle in more recent years. We analyzed uniparental genetic markers and autosomal microsatellites in DNA samples from 114 cattle breeds distributed worldwide, including 40 Creole breeds representing the whole American continent, and samples from the Iberian Peninsula, British islands, Continental Europe, Africa and American zebu. We show that Creole breeds differ considerably from each other, and most have their own identity or group with others from neighboring regions. Results with mtDNA indicate that T1c-lineages are rare in Iberia but common in Africa and are well represented in Creoles from Brazil and Colombia, lending support to a direct African influence on Creoles. This is reinforced by the sharing of a unique Y-haplotype between cattle from Mozambique and Creoles from Argentina. Autosomal microsatellites indicate that Creoles occupy an intermediate position between African and European breeds, and some Creoles show a clear Iberian signature. Our results confirm the mixed ancestry of American Creole cattle and the role that African cattle have played in their development
