Los derechos fundamentales como normas jurídicas materiales en la teoría de Robert Alexy
2011
RESUMEN. La teoría de los derechos fundamentales de Robert Alexy se fundamenta en un concepto material de norma jurídica que es de carácter doble. Por un lado, se define por los rasgos propios de los principios, en consonancia con la idea de argumentación correcta. Pero, por otro lado, sigue teniendo peso la validez jurídica de las normas que contienen derechos fundamentales, consideradas como reglas constitucionales. Tal y como se argumenta en el trabajo, esta ambigüedad de la teoría de la norma de Alexy permite distintos acercamientos, positivistas y no positivistas, que es signo de su riqueza teórica. ABSTRACT. The theory of the civil rights of Robert Alexy is based on a material concept…
Determination of n-alkanes, polycyclic aromatic hydrocarbons and hopanes in atmospheric aerosol: evaluation and comparison of thermal desorption GC-M…
2019
Organic aerosol (OA) constitutes a large fraction of fine particulate matter (PM) in the urban air. However, the chemical nature and sources of OA are not well constrained. Quantitative analysis of OA is essential for understanding the sources and atmospheric evolution of fine PM, which requires accurate quantification of some organic compounds (e.g., markers). In this study, two analytical approaches, i.e., thermal desorption (TD) gas chromatography mass spectrometry (GC-MS) and solvent extract (SE) GC-MS, were evaluated for the determination of n-alkanes, polycyclic aromatic hydrocarbons (PAHs) and hopanes in ambient aerosol. For the SE approach, the recovery obtained is 89.3 %–101…
Bromine speciation in volcanic plumes: new in situ derivatization LC-MS method for the determination of gaseous hydrogen bromide by gas diffusion den…
2020
The chemical characterization of volcanic gas emissions gives insights into the interior of volcanoes. Monitoring of BrO/SO2-ratios has recently been correlated with changes in the activity of a volcano. BrO and SO2 can both be measured autonomously and simultaneously with the same instruments from a safe distance, making their ratio potentially a strong monitoring tool. However, BrO is not a primary emitted volcanic volatile and there exist still uncertainties about the formation of BrO in volcanic plumes, mostly due to the lack of analytical approaches for the accurate speciation of certain key compounds. This study describes a new method for the determination of the BrO precursor, the ga…
Las representaciones del saber académico: Aportaciones desde la Geografía Escolar
2019
When we talk with basic education´s teachers there is an impression in the case of learning Social Sciences, and Geography in particular that these sciences are not useful for the explanation of socio-environmental and daily problems. In this research, improvement proposals are sought so that students are motivated to learn about these problems. Based on two case studies such as flood risks (and their relationship with climate change) and the problems of the rural areas, the possibilities of combining motivation for learning close to personal emotions and with their own rigor have been explored of the conceptual explanation. To validate these results, quantitative and qualitative research t…
Vor-und Nachteile der Digitalisierung bei der Arbeit von Sprachexpertinnen und –experten
2020
While the future of work is discussed from many perspectives, discussions on how an individual's own work tasks are changing are relatively rare (Dufva et al. 2017). This article builds on our alumni study (Selkälä, Tahkokorpi & Virtaluoto 2018), in which we discovered that despite the perceived changes in working life - often called the disruption of work - the foreign language alumni of the Oulu University have found permanent positions in the traditional professions of language graduates with relative ease. For them, the disruption of work has not affected employability or the terms of employment. To investigate how working life has changed for people in these professions, we gathered gr…
Educar jugando y dialogando. Derechos de la infancia, intencionalidad, familia y lenguaje
2019
[EN] The article reviews the rights that contribute to the achievement of a happy life from childhood and seizes on the key elements that seek dignity in order to develop happiness. First, the role of the family in setting up personal identity and security, and in establishing personal relationships. Second, the integral personal training and the education in the development of the critical sense and freedom for responsible exercise, as well as the ability to understand, express and communicate to improve or overcome problematic situations. Finally, gambling, as a basic tool of enjoyment in childhood, and, at the same time, learning in the two previous domains, sometimes unique complement o…
Hybrid Engagement: Discourses and Scenarios of Entrepreneurial Journalism
2018
Although the challenge posed by social media and the participatory turn concerns culture and values at the very heart of journalism, journalists have been reluctant to adopt participatory values and practices. To encourage audience participation and to offer journalism that is both trustworthy and engaging, journalists of the future may embrace a hybrid practice of journalistic objectivity and audience-centred dialogue. As innovative and experimental actors, entrepreneurial journalism outlets can perform as forerunners of such a culture. By analysing discourses in the “About Us” pages of 41 entrepreneurial journalism outlets, the article examines the emerging journalistic ethos of entrepren…
Diseño de letras en carteles y cabeceras del imaginario Disney
2020
espanolEn el presente articulo analizamos los disenos de letras del imaginario Disney desde la cultura visual. Indagamos en los estilos que han marcado algunas de las producciones mas emblematicas de esta productora de cine, para lo cual se seleccionan como muestra 12 filmes representativos de los 60 titulos que componen la coleccion Clasicos Disney. Abordamos la cuestion desde una revision estilistica, estudiando las caracteristicas formales y observando el papel de cada diseno en su coyuntura historica, mediante un estudio de caso, analizando de que modo comunicacion y tecnologia se dan la mano en esta evolucion estilistica. Tambien aportamos una com-ponente educativa, atendiendo a nuestr…
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…
Documentário ficcional e responsabilidade social: a recriação da violência de gênero na televisão
2020
espanolO tratamento da violencia de genero tem experimentado uma notavel mudanca nos meios de comunicacao espanhois nas ultimas duas decadas. Propiciada pela conscientizacao e pela publicacao de codigos eticos, essa evolucao e caracterizada por abandonar o discurso que delimitava a violencia contra as mulheres na cronica de acontecimentos para aborda-la em sua dimensao de problema social com causas estruturais. Contudo, os avancos na cobertura informativa contrastam com o surgimento de modelos de docuficcao, que combinam o depoimento das vitimas e seu contexto com reconstrucoes ficcionais. Esta pesquisa tem como objetivo indagar o tratamento que esses modelos oferecem, a partir da analise d…
