Finalidades de la enseñanza de las ciencias en la Secundaria obligatoria. ¿Alfabetización científica o preparación propedéutica?
2001
Resumen basado en el de la revista El propósito de este trabajo es encontrar las ideas, propósitos y objetivos de los profesores de ciencias dentro del marco de las reformas educativas. Se trata de revelar en que medida el pensamiento educativo da prioridad a la enseñanza de los estudiantes en los conceptos científicos, leyes y teorías necesarias en cursos superiores (capacitación propedéutica) y como este pensamiento presta menos atención a la llamada alfabetización científica lo cual se suponía iba a ser el principal objetivo de la enseñanza de ciencias de acuerdo con los diseños del currículum . Al lograr esto, se lleva a cabo un diseño experimental multiple y convergente con un múmero d…
International positioning of the Spanish psychology journals
2020
[ES]: Se presentan los resultados del análisis de la difusión y circulación del número de revistas españolas en diferentes bases de datos, nacionales e internacionales. Para ello se realiza un estudio de las revistas que contienen las principales bases de datos bibliográficas hasta el año 2017. El aumento de la presencia de revistas españolas de psicología en las diferentes bases de datos es un indicador que determina el crecimiento y la madurez de esta disciplina y aporta una visión interesante de la actividad científica en psicología y su situación en el contexto internacional. Se muestra que las políticas de estado y las campañas de posicionamiento de universidades, asociaciones y colegi…
What Counts in the Politics of Climate Change? Science, Scepticism and Emblematic Numbers
2019
Scientific data is frequently presented in climate policy in the form of targets, thresholds and other “emblematic numbers”. Emblematic numbers provide putatively accurate, easily graspable units of comparison. Their use, however, belies the complexity of climate change and scientific data and threatens to mask the political decisions that operate behind them. Those interested in disrupting policymaking are able to expose and exploit this masked politicisation. This contribution unpicks the ambiguous politics of emblematic numbers. A Qualitative Content Analysis of the 2015 NIPCC report reveals the tactics of a climate change denial organisation to target the politics behind “97%” and “95%”…
Batch fermentation process: Modelling and direct sensitivity analysis
2009
Based on a nonlinear model, this article realizes an investigation of dynamic behaviour of a batch fermentation process using direct sensitivity analysis (DSA). The used nonlinear mathematical model has a good qualitative and quantitative description of the alcoholic fermentation process. This model has been discussed and validated by authors in other studies. The DSA of dynamic model was used to calculate the matrix of the sensitivity functions in order to determine the influence of the small deviations of initial state, control inputs, and parameters from the ideal nominal values on the state trajectory and system output in time. Process optimization and advanced control strategies can be…
Results of a literature review on methods for estimating buildings energy demand at district level
2019
Abstract In the framework of distributed energy planning, evaluating reliable energy profiles of different sectors has a prominent role. At the same time, it is a quite challenging task, since the availability of actual energy profiles of buildings at the district level is not widespread. A survey of over 70 studies in scientific literature has been accomplished and a set of criteria has been defined for classifying the selected contributions based on the energy demand data features, source and/or estimation methods, highlighting the ones adopting hourly energy profiles. As final results, tables summarizing the main methods characteristics and a selection of studies providing directly useab…
La investigación universitaria en periodismo científico
2003
En este artículo, la autora revisa y examina las aportaciones bibliográficas sobre comunicación científica que se han realizado desde distintas áreas de conocimiento, en las últimas décadas en nuestro país. Así pues, muestra las debilidades presentes en los escasos estudios sobre el tratamiento informativo de la ciencia y la tecnología, realizados desde las facultades de Ciencias de la Información y la fortaleza de los trabajos abordados desde las facultades de Ciencias Experimentales donde hay abierta una línea de investigación sobre historia del periodismo científico. In this article, the author revises and she examines the bibliographical contributions about scientific communication that…
Organisation et conditions de la formation des doctorants dans le cadre de l'université française
2007
This research, refering to the theoretical framework of Pierre Bourdieu, shows that higher education can be considered as a “champ scientifique”, defined as a microcosm, relatively autonomous from the economic and social macrocosm, nevertheless strongly affected by its values and its evolution toward liberalism. This evolution is clearly perceveid in the structural reforms (contractualization, decentralization, increased autonomy...) inferred notably by the construction of the European Higher Education and Research Area. Higher education is structured in a hierarchy with dominating disciplines (mathematics, physique, chemistry...) at the center and, dominated disciplines (Social sciences an…
Scientific power in the Spanish press during the Pandemic : a portrait of new leaders while explaining its risk
2021
This work is based on the mediatisation of society theory, which establishes more attached importance and the presence of the mass media as mediators in various social processes, as well as on Production Studies, that analyse creative skills to draw an audience, to apply these theories to the media representation of the COVID-19 pandemic. The objective is to analyse how the generalist media have represented male/female scientists, who have become social benchmarks during the first COVID-19 wave in Spain. Our initial hypothesis considers that the purpose of the mediatisation of scientific discourse was to contribute answers to, and to keep society calm, in an uncertainty context. By content …
Oral manifestations in drug users : a review
2020
Background: In the dental environment there is not much talk about the oral manifestations resulting from the use of drugs, because in general the issue of drugs is a very difficult subject to deal with. Therefore, the objective of this work is to understand what are the most obvious manifestations in the oral cavity and as the dentist can detect them. Material and Methods: In order to carry out this bibliographical review, a scientific article search was made by consulting the PubMed database. The abstracts were read to recruit only what was consistent with the chosen topic. Results: The 23 sources of information affirmed the relationship between a bad state of general health, and more in …
