Ideology of objectivity in political journalism. Attitudes, values and beliefs around truth as a possible horizon?

Desde un enfoque crítico-discursivo se analizan contenidos automáticos y reflexivos en torno a la “objetividad”, como código estilístico-normativo y dispositivo cultural de contornos míticos, compartido por periodistas y audiencias de la información política. Con base en entrevistas realizadas bajo un enfoque etnográfico entre 2012 y 2014, a profesionales de diferentes medios masivos de Córdoba-Argentina, primero se discuten la auto-percepción de su rol contemporáneo y las condiciones de su vínculo cotidiano con fuentes y acontecimientos. Dado el carácter inter-subjetivo del fenómeno, en un segundo momento se incluye el contraste entre las perspectivas periodísticas y las percepciones de audiencias locales, recopiladas en sesiones experimentales simultáneas. Mediante una estrategia de triangulación analítica, se advierte un significativo vínculo de circularidad entre definiciones profesionales y expectativas de consumo.From a critical-discursive approach, automatic and reflexive contents are analyzed around "objectivity", as a stylistic-normative code and cultural device with mythical contours, shared by journalists and audience of political information. Based on interviews to professionals from different mass media in Córdoba-Argentina (conducted under an ethnographic approach between 2012 and 2014), firstly the self-perception of their contemporary role and the conditions of their daily link with sources and events are discussed. Given the inter-subjective nature of the phenomenon, in a second moment the contrast between the journalistic perspectives and the perceptions of local audiences, gathered in simultaneous experimental sessions, is included. Through an analytical triangulation strategy, a significant circularity link between professional definitions and consumption expectations is noticed.From a critical-discursive approach, automatic and reflexive contents are analyzed around “objectivity”, as a stylistic-normative code and cultural device with mythical contours, shared by journalists and audience of political information.

A 300 GHz "Always-in-Focus" Focusing System for Target Detection

A focusing system for a 300 GHz radar with 5 m target distance and 10 mm diameter spot size resolution is proposed. The focusing system is based on a Gaussian telescope scheme and its main parameters have been de¬signed using Gaussian beam quasi-optical propagation theory with an in-house developed MATLAB® based analysis tool. Then, this approach has been applied to a real focusing system based on two elliptical mirrors in order to reduce the distortion and cross-polar level and a plane mirror to provide scanning capabilities. The over¬all system has been simulated with a full-wave electromag¬netic simulator and its behavior is presented. With this approach, the focusing system always works "in-focus" since the only mirror that is rotated when scanning is the output plane mirror, so the beam is almost not distorted. The design process, although based in the well-known Gaussian beam quasi-optical propagation theory, provides a fast and accurate method and minimizes the overall size of the mirrors. As a consequence, the size of the focusing system is also reduced

O problema da opinião pública no pensamento sociológico de Habermas, Luhmann e Bourdieu: discussões políticas, comunicacionais e ideológicos sobre um fenômeno ¿democrático?

Se discute aquí el carácter de la “opinión pública” como categoría conceptual en el marco de las perspectivas de Jürgen Habermas, Niklas Luhmann y Pierre Bourdieu. Sus lecturas sobre este fenómeno psico-socio-político y comunicativo, todavía polémico dentro del debate sobre las formas sociales de la democracia representativa, se abordan considerando: primero, la relación de continuidad de sus propuestas con las principales tradiciones de la teoría social contemporánea; segundo, su potencialidad crítica para un esclarecimiento sociológico de la relación entre opinión pública y “medios masivos de comunicación”; tercero, sus diferentes concepciones del “espacio público” como categoría central o residual en la comprensión del sentido de la acción social.This paper discusses the character of “public opinion” as a conceptual category within the perspectives of Jürgen Habermas, Pierre Bourdieu and Niklas Luhmann.

Modeling of Electrokinetic Remediation Combining Local Chemical Equilibrium and Chemical Reaction Kinetics

A mathematical model for reactive-transport processes in porous media is presented. The modeled system includes diffusion, electromigration and electroosmosis as the most relevant transport mechanism and water electrolysis at the electrodes, aqueous species complexation, precipitation and dissolution as the chemical reactions taken place during the treatment time. The model is based on the local chemical equilibrium for most of the reversible chemical reactions occurring in the process. As a novel enhancement of previous models, the local chemical equilibrium reactive-transport model is combined with the solution of the transient equations for the kinetics of those chemical reactions that have representative rates in the same order than the transport mechanisms. The model is validated by comparison of simulation and experimental results for an acid- enhanced electrokinetic treatment of a real Pb-contaminated calcareous soil. The kinetics of the main pH buffering process, the calcite dissolution, was defined by a simplified empirical kinetic law. Results show that the evaluation of kinetic rate entails a significant improvement of the model prediction capability.This work has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 778045.

Multiphysics modeling of a wastewater treatment plant

Wastewater treatment plants (WWTP) are special structures designed to purify wastewater. The main objective of this work is to model the WWTP from Antequera (Malaga, Spain). The model consists of two combined simulations: (1) a 0D biological plug-flow reactor in a stationary state, establishing the concentration profiles at along the volume of the multizone reactor and, (2) a 3D clarifier. The model is based on global material balances of the WWTP has been done, based on the information from the concentrations that exist in a stationary state in each of the streams. Through this work, detailed description of two of the most important parts of the WWTP have been modeled. The results will be used in future works related to optimizing the use of these facilities for real problems related to controlling the phosphorus and nitrogen levels in the secondary effluent.Universidad de Málaga.

Void Dynamics

Cosmic voids are becoming key players in testing the physics of our Universe. Here we concentrate on the abundances and the dynamics of voids as these are among the best candidates to provide information on cosmological parameters. Cai, Padilla \& Li (2014) use the abundance of voids to tell apart Hu \& Sawicki $f(R)$ models from General Relativity. An interesting result is that even though, as expected, voids in the dark matter field are emptier in $f(R)$ gravity due to the fifth force expelling away from the void centres, this result is reversed when haloes are used to find voids. The abundance of voids in this case becomes even lower in $f(R)$ compared to GR for large voids. Still, the differences are significant and this provides a way to tell apart these models. The velocity field differences between $f(R)$ and GR, on the other hand, are the same for halo voids and for dark matter voids. Paz et al. (2013), concentrate on the velocity profiles around voids. First they show the necessity of four parameters to describe the density profiles around voids given two distinct void populations, voids-in-voids and voids-in-clouds. This profile is used to predict peculiar velocities around voids, and the combination of the latter with void density profiles allows the construction of model void-galaxy cross-correlation functions with redshift space distortions. When these models are tuned to fit the measured correlation functions for voids and galaxies in the Sloan Digital Sky Survey, small voids are found to be of the void-in-cloud type, whereas larger ones are consistent with being void-in-void. This is a novel result that is obtained directly from redshift space data around voids. These profiles can be used to remove systematics on void-galaxy Alcock-Pacinsky tests coming from redshift-space distortions.Comment: 8 pages, 4 figures, to appear in the proceedings of IAU308 Symposium "The Zeldovich Universe

Influence of chemical reaction kinetics on electrokinetic remediation modelling results

A numerical model describing transport of multiple species and chemical reactions during electrokinetic treatment is presented. The transport mechanisms included in the model were electromigration and electroosmosis. The chemical reactions taken into account were water electrolysis at the electrodes, aqueous species complexation, precipitation, and dissolution. The model was applied to simulate experimental data from an acid-enhanced electrokinetic treatment of a Pb-contaminated calcareous soil. The kinetics of the main pH buffering process (i.e., calcite dissolution) was taken into account and its time-dependent behavior was described by a rate law. The influence of kinetics was evaluated by comparing the results from a set of simulations in which calcite dissolution was implemented considering thermodynamic equilibrium and another set in which the same reaction was described by the rate law. The results show that the prediction capability of the model significantly improves when the kinetic rate is taken into account.Universidad de Málaga.

Osteosarcoma extraóseo Presentación de 1 caso y revisión de la literatura

Se presenta un caso de los no frecuentes osteosarcomas extraóseos, con localización en el muslo y que cursó con varias recidivas hasta su fallecimiento por metástasis pulmonares. En la revisión de la bibliografía se puede comprobar que este tipo de tumores tienen una malignidad mayor de la habitualmente reconocida, estando en algunos casos en relación con el empleo de radiaciones ionizantes, con miositis osificantes, con extravasación de líquidos de contraste y con inyecciones intramusculares. Su único tratamiento es la exéresis ablativa, aunque tienen una alta tasa de recidivas.A case of extraosseous osteogenic sarcoma siting in the thigh with a warming follow-up because he was complicated with several recurrences within two years until his exitus is reported. In the revision of the literature is common to see that this tumour has a worse malignant behaviour, and has also a clear relationship in some cases with the use of radiations, with myositis ossificans following intramuscular inyection or by extravessels liquid inyection. The treatment must be a complete ablative surgery although the number of recurrences is ussually high

Ideological Profile of Political Information Media Consumption in Córdoba, Argentina

Recuperando el papel de la ideología como componente clave de la cultura política y considerando el rol de los medios masivos de comunicación como agentes y referentes ideológicos, este trabajo sintetiza resultados parciales de una investigación mayor sobre las condiciones psico-socio-políticas que intervienen en la estructuración de las prácticas cotidianas de consumo de información política. Primero, se discuten las condiciones de selectividad ideológica de las audiencias, entendiendo al consumo mediático de información política como práctica socio-cultural. Segundo, se describe el contexto del mercado local en la ciudad de Córdoba-Argentina, y en el plano metodológico se informan las bases teóricas y técnicas del Análisis de Clases Latentes, como método probabilístico de particular utilidad en la modelización de comportamientos complejos. Mediante la aplicación de este procedimiento a los datos de una encuesta poblacional semi-estructurada realizada en 2010 sobre una muestra por cuotas de 395 cordobeses, se identifican perfiles transversales al consumo informativo en televisión, diarios y radio, sin dejar de reconocer la especificidad con que sus preferencias se enmarcan dentro de cada formato mediáticoRecovering the role of ideology as a key element of political culture and taking into consideration the role of mass communication media as ideological agents and references, this article is a summary of partial results of a major research about the psychological, social, and political conditions involved when structuring daily life political information consumption practice. First, ideological selectivity conditions of audiences are discussed, understanding political information media consumption as a sociocultural practice. Second, local market context in Córdoba, Argentina is described and theoretical and technical grounds of the Latent Class Analysis are informed in the methodological field as a probabilistic method particularly used for modeling complex behaviors. By applying this procedure to the data of a semi-structured population survey performed in 2010 over a sample of 396 locals of Córdoba City, profiles transversal to the information consumption in television, newspapers, and radio are identified without recognizing the specificity with which locals' preferences are inserted within each media format.Fil: Paz Garcia, Ana Pamela.
