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…
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 …
CFD Simulation of Particle Distribution in Stirred Vessels
2000
In this work the particle concentration distribution in two-phase stirred tanks is simulated on the basis of information on the three-dimensional flow field, as obtained by numerical solution of the flow equations (CFD) using the well known k –ɛ « turbulence model. Two modelling approaches are attempted. In the simpler method the flow field is first simulated neglecting the influence of the solid phase; on the basis of the resulting flow field a very simple sedimentation model is employed for solving the solids mass balance equations in order to compute the particle concentration field. In this case no inertial effects on the solid particles are considered, so that the convective and diffus…
Stolen innocence? Observance of the EU Directive on presumption of innocence by Spanish crime reporting
2021
This paper examines the compliance of Spanish crime reporting with the principles of the 2016 EU Directive on presumption of innocence, which aims at preventing the publication of information that might bias the public and the jurors against the suspect. A content analysis applied to a sample of 200 crime news stories published by eleven of the most popular print and online news platforms in 2018 reveals that the Spanish press coverage of crime is centered around the pre-trial and sentence stages, with little attention to the oral trial. The full name and the face portrait of the suspect appear in roughly one-third of the stories, but this overwhelmingly happens in news stories reporting on…
A multidisciplinary approach to the evaluation of the mechanism that triggered the Cerda landslide (Sicily, Italy).
2005
Abstract The present paper describes a multidisciplinary approach to the evaluation of a seismically triggered landslide that occurred in the Cerda area (Italy) on September 6, 2002, about 1 h after an earthquake took place in the south Tyrrhenian Sea. The study was focused on an analysis of the role of the seismic input in triggering the landslide, in view of the evidence that no other mass movement was recorded in the adjacent areas despite geological and geomorphological spatial homogeneity. The studied area is located on a slope of the western flank of the Fiume Imera Settentrionale (Northern Sicily), which is made up of clayey–arenitic rocks. The slope inclines gently but is not unifor…
Jóvenes y uso problemático de las tecnologías durante la pandemia: una preocupación familiar
2021
espanolLa situacion de confinamiento, derivada de la pandemia mundial por la COVID-19, ha supuesto un cambio drastico en nuestras conductas en las diferentes esferas de nuestra vida. Asi, el desempeno de las actividades laborales, el afrontamiento de las responsabilidades academicas y la ocupacion del tiempo de ocio se han visto condicionadas por una limitacion de la movilidad y una mayor permanencia en el hogar. El confinamiento se ha vinculado a un mayor consumo de tecnologia en sus diferentes formatos, generando una preocupacion en el entorno familiar por un uso excesivo de ellas, asi como de las posibles consecuencias que podrian derivarse. Bajo esta perspectiva, el presente estudio pre…
Numerical model of turbulent CZ melt flow in the presence of AC and CUSP magnetic fields and its verification in a laboratory facility
2001
The paper describes a numerical simulation tool for heat and mass transfer processes in large diameter CZ crucibles under the influence of several non-rotating AC and CUSP magnetic fields. Such fields are expected to provide an additional means to influence the melt behaviour, particularly in the industrial growth of large diameter silicon crystals. The simulation tool is based on axisymmetric 2D models for the AC and CUSP magnetic fields in the whole CZ facility and turbulent hydrodynamics, temperature and mass transport in the melt under the influence of the electromagnetic fields. The simulation tool is verified by comparisons to experimental results from a laboratory CZ setup with eutec…
Influence of combined electromagnetic fields on the heat/mass transfer in the Bridgman process
2002
The influence of combined magnetic fields (travelling and rotating) on the characteristics of heat/mass transfer with an aim to obtain the needed profile of the interface is considered, that is a necessary condition, which insures the homogeneity of single crystal content. The crystallization process of a cylindrical sample is considered. It was presumed that the sample moves with a permanent velocity towards the cold part of the heater and a partial-linear temperature distribution characteristic to the Bridgman method was set in along the heater's length. Permanent temperature values were set in on the top and bottom edges of the calculation mesh. It has been shown that combinations of dif…
Comunicar : revista científica iberoamericana de comunicación y educación
2021
En el marco de la escuela inclusiva, el aprendizaje socioemocional y personalizado fomenta la implicación del alumnado en la vida del aula y se relaciona con la disminución de la conducta desadaptativa. El objetivo de este estudio es analizar el impacto de un programa de educación socioemocional en la agresividad y la inestabilidad emocional en la infancia. Han participado 555 niños/as de 7 a 12 años (M=9,2 y DT=1,5), 55,5% niños y 45,5% niñas. Estudian Educación Primaria en seis colegios públicos del área metropolitana de Valencia (España). La muestra se ha distribuido en un grupo experimental (317 niños/as; 57,2% de la población total participante) y un grupo control (238 niños/as; 42,8% …
Reciprocal Effects: Toward a Theory of Mass Media Effects on Decision Makers
2007
The article presents a framework for the analysis of reciprocal effects of mass media—in this case, their impact on subjects of media reports, especially on decision makers in areas of politics and business. It outlines a feedback model with three sets of variables referring to (1) media coverage and media as institutions, (2) awareness and processing of information, and (3) observable effects on subjects and others.The article presents several theories that explain effects on decision makers and illustrate the relevance of this approach with empirical data from a broad range of quantitative studies. In the final section, theoretical and methodological problems of such an approach are discu…
