Metodología de la enseñanza y formación del profesorado : El caso de la Sección Pedagógica y la Facultad de Ciencias de la Educación de la Universidad Nacional de La Plata entre 1906 y 1920

En este trabajo investigamos la Metodología de la enseñanza como asignatura y como habilidad del desempeño profesional en la formación inicial de los profesores en la Sección Pedagógica entre 1906 y 1914, y en la Facultad de Ciencias de la Educación entre 1914 y 1920, ambas en la Universidad Nacional de La Plata. Dicha formación se gestó y desarrolló en el marco de un proyecto fundacional integral para nuestra Universidad. Estudiamos desde una perspectiva curricular la formación inicial de los profesores, es decir, aquella instancia institucional y formal de preparación para el ejercicio de la docencia. Aparecen en un segundo plano de importancia referencias al ejercicio profesional en tanto algunas prescripciones pedagógicas y didácticas resultaban también recomendadas para los docentes ya recibidos. Recurrimos al análisis de documentos. Tomamos como universo de análisis las Revistas Archivos de Pedagogía y Ciencias Afines y Archivos de Ciencias de la Educación que, en tanto órgano de difusión de las instituciones mencionadas, nos aportaron valiosos elementos para la reconstrucción de los trayectos formativos de los profesorados y para conocer ciertas características generales adjudicadas a la Metodología de la enseñanza. También utilizamos escritos de Víctor Mercante y otros de Joaquín V. González, quienes fueron referentes claves en la concreción de la formación de docentes en nuestra Universidad. Visualizamos la presencia de un sustento positivista tiñendo diferentes dimensiones formativas: la secuencia y organización de las asignaturas del curriculum, en las que predominaría una supremacía de la teoría sobre la práctica; la exigencia de complementar las lecciones teóricas con instancias de observación y experimentación; las constantes y dominantes manifestaciones sobre la principalidad de la ciencia. Además, a partir del estudio de los programas de "Metodología general" y "Metodología especial" como asignaturas del curriculum, y de la concepción de Mercante sobre éstas, pudimos inferir una confianza depositada en que un buen uso de la Metodología de la enseñanza facilitaría un desempeño profesional eficaz. En el interjuego permanente entre el marco conceptual-referencial y el material empírico, construimos dos ejes a partir de los cuales analizar esa Metodología de enseñanza. El primero es de carácter curricular e incluye, por un lado, entenderla como asignatura del curriculum de la formación de profesores y, por el otro, como una habilidad profesional conformando parte de las intencionalidades formativas de éste. El segundo eje se arma entendiendo a la Metodología de enseñanza como una habilidad del profesional docente que facilita el desempeño en el aula, y a esta habilidad como un lugar reservado para la normatividad del saber pedagógico. Esta mirada histórica sobre los orígenes de la formación docente en nuestra Casa de Estudios, pretende aportar elementos para la reflexión curricular actual sobre la formación de formadores. A su vez, en un segundo plano, nos interesa destacar la presencia y características de un espacio de normatividad/prescripción propio del saber pedagógico de la época. En los debates didácticos actuales, cobra relevancia la conformación de ese componente normativo/prescriptivo, por lo que consideramos que la perspectiva de estudio aquí propuesta nos aporta elementos para enriquecer la reflexión.

Contents and isotopic composition of black carbon from ODP Sites 184-1147 and 184-1148

A 30 m.y. stable isotopic record of marine-deposited black carbon from regional terrestrial biomass burning from the northern South China Sea reveals photosynthetic pathway evolution for terrestrial ecosystems in the late Cenozoic. This record indicates that C3 plants negatively adjusted their isotopic discrimination and C4 plants appeared gradually as a component of land vegetation in East Asia since the early Miocene, a long time before sudden C4 expansion occurred during the late Miocene to the Pliocene. The changes in terrestrial ecosystems with time can be reasonably related to the evolution of East Asian monsoons, which are thought to have been induced by several intricate mechanisms during the late Cenozoic and could contribute significantly to the post-Miocene marine carbonate isotope decline.

Grid-connected roof solar plants in educational institutions for testing and electricity generation: a case in Spain.

The use of photovoltaic experimental plants in engineering educational buildings contributes to an increase in acceptance of this technology by future engineers. There are some photovoltaic (PV) systems in educational buildings in Spain, but they are usually limited to buildings in relation to electrical technologies or research areas. They are not common in other educational or official buildings. This paper presents the project of a grid-connected solar plant with two main objectives. First, different PV module technologies will be compared. Second, an emphasis on agronomical areas in educational settings will be reviewed in an attempt to facilitate student engagement in the use of the power plant. The system is grid-connected in order to pay-back the investment in the plant. In fact the electricity generated by the plant will be used by the installations of the building, as it is the closest consumer. This work intends to approximate photovoltaic technology to university degrees not directly related with it and at the same time research in comparison of systems with different technologies. This is a good example of an solar plant for both optimum production and educational purposes.

Design and evaluation of an educational platform for implementing and testing bilateral control algorithms

This paper describes the design and evaluation of a new platform created in order to improve the learning experience of bilateral control algorithms in teleoperation. This experimental platform, developed at Universidad Politécnica de Madrid, is used by the students of the Master on Automation and Robotics in the practices of the subject called “Telerobotics and Teleoperation”. The main objective is to easily implement different control architectures in the developed platform and evaluate them under different conditions to better understand the main advantages and drawbacks of each control scheme. So, the student’s tasks are focused on adjusting the control parameters of the predefined controllers and designing new ones to analyze the changes in the behavior of the whole system. A description of the subject, main topics and the platform constructed are detailed in the paper. Furthermore, the methodology followed in the practices and the bilateral control algorithms are presented. Finally, the results obtained in the experiments with students are also shown.

On the mechanism of action of ribonuclease A: relevance of enzymatic studies with a p-nitrophenylphosphate ester and a thiophosphate ester.

It has been reported that His-119 of ribonuclease A plays a major role as an imidazolium ion acid catalyst in the cyclization/cleavage of normal dinucleotides but that it is not needed for the cyclization/cleavage of 3'-uridyl p-nitrophenyl phosphate. We see that this is also true for simple buffer catalysis, where imidazole (as in His-12 of the enzyme), but not imidazolium ion, plays a significant catalytic role with the nitrophenyl substrate, but both are catalytic for normal dinucleotides such as uridyluridine. Rate studies show that the enzyme catalyzes the cyclization of the nitrophenylphosphate derivative 47,000,000 times less effectively (kcat/kuncat) than it does uridyladenosine, indicating that approximately 50% of the catalytic free energy change is lost with this substrate. This suggests that the nitrophenyl substrate is not correctly bound to take full advantage of the catalytic groups of the enzyme and is thus not a good guide to the mechanism used by normal nucleotides. The published data on kinetic effects with ribonuclease A of substituting thiophosphate groups for the phosphate groups of normal substrates has been discussed elsewhere, and it was argued that these effects are suggestive of the classical mechanism for ribonuclease action, not the novel mechanism we have recently proposed. The details of these rate effects, including stereochemical preferences in the thiophosphate series, can be invoked as support for our newer mechanism.

Vertical crustal motion along the Mediterranean and Black Sea coast derived from ocean altimetry and tide gauge data

Tide gauge (TG) data along the northern Mediterranean and Black Sea coasts are compared to the sea-surface height (SSH) anomaly obtained from ocean altimetry (TOPEX/Poseidon and ERS-1/2) for a period of nine years (1993–2001). The TG measures the SSH relative to the ground whereas the altimetry does so with respect to the geocentric reference frame; therefore their difference would be in principle a vertical ground motion of the TG sites, though there are different error sources for this estimate as is discussed in the paper. In this study we estimate such vertical ground motion, for each TG site, from the slope of the SSH time series of the (non-seasonal) difference between the TG record and the altimetry measurement at a point closest to the TG. Where possible, these estimates are further compared with those derived from nearby continuous Global Positioning System (GPS) data series. These results on vertical ground motion along the Mediterranean and Black Sea coasts provide useful source data for studying, contrasting, and constraining tectonic models of the region. For example, in the eastern coast of the Adriatic Sea and in the western coast of Greece, a general subsidence is observed which may be related to the Adriatic lithosphere subducting beneath the Eurasian plate along the Dinarides fault.

A Black Knight in the Eastern Neighbourhood? Russia and EU Democracy Promotion in Armenia and Moldova. EU Diplomacy Paper No. 7, October 2014

Europe’s peace and security are challenged by the events taking place in the Eastern Partnership region. Amid growing tensions between the European Union (EU) and Russia, the fate of countries in the common neighbourhood and their progress towards democracy are increasingly at stake. This paper tries to understand to what extent Russia is undermining EU democracy promotion in the Union’s eastern neighbourhood. By focusing on the cases of Armenia and Moldova, EU democracy promotion is analysed in light of the triangular relationship between the countries under scrutiny, the EU and Russia. It argues that domestic conditions and external pressures, linked through the filter of problems of ‘stateness’, are both crucial and mutually reinforcing for democratisation. The paper shows that Russia can undermine EU democracy promotion to the extent that it strengthens the aversion of domestic political forces to democracy-oriented reforms.
