Jornalismo televisivo de ciência e ambiente: O caso dos telejornais de Domingo da SIC

O jornalismo de ciência e de ambiente é um campo pouco estudado em Portugal. Esta investigação apresenta-se com o objetivo de compreender e caracterizar a mediatização de temas científicos e ambientais, tendo como ponto de partida os telejornais de Domingo da Sociedade Independente de Comunicação (SIC). Procurou-se essencialmente perceber qual a representatividade destes temas nos telejornais através da análise dos alinhamentos, bem como o destaque, o género jornalístico predominante e o tipo de jornalistas que realizam peças sobre as temáticas em estudo. O presente relatório resulta e reflete uma experiência pessoal acumulada durante um estágio, com a duração de seis meses, na redação da SIC, do qual resultaram também conclusões pertinentes através da observação participante.

Extending the irrelevant sound effect beyond serial recall

The finding that serial recall perfonnance for visually presented items is impaired by concurrently presented speech or sounds is referred to as the irrelevant sound effect (lSE). The foremost explanation for the effect is based on interference with rehearsal and seriation processes. The present series of experiments demonstrates tha t neither rehearsal nor seriation processes is necessary to observe the ISE. Evidence comes from three experiments that a) allow participants to report to-be-remembered items in any order, b) eliminate rehearsal by engaging participants in a cover task and surprising them with a memory test, and c) show that surprise non-serial recognition is immune to rehearsal-based experimental manipulations that modulate the ISE in more typical serial recall tasks. Together,the results show that models that rely on rehearsal or seriation processes to account for the ISE need to be reconsidered. Results are discussed in tenns of interference with encoding of to-be-remembered material.

Estimating the Tobit Model with Serial Correlation: an Operational Approach

Several Authors Have Discussed Recently the Limited Dependent Variable Regression Model with Serial Correlation Between Residuals. the Pseudo-Maximum Likelihood Estimators Obtained by Ignoring Serial Correlation Altogether, Have Been Shown to Be Consistent. We Present Alternative Pseudo-Maximum Likelihood Estimators Which Are Obtained by Ignoring Serial Correlation Only Selectively. Monte Carlo Experiments on a Model with First Order Serial Correlation Suggest That Our Alternative Estimators Have Substantially Lower Mean-Squared Errors in Medium Size and Small Samples, Especially When the Serial Correlation Coefficient Is High. the Same Experiments Also Suggest That the True Level of the Confidence Intervals Established with Our Estimators by Assuming Asymptotic Normality, Is Somewhat Lower Than the Intended Level. Although the Paper Focuses on Models with Only First Order Serial Correlation, the Generalization of the Proposed Approach to Serial Correlation of Higher Order Is Also Discussed Briefly.

Nearly Serial Sharing Methods

A group of agents participate in a cooperative enterprise producing a single good. Each participant contributes a particular type of input; output is nondecreasing in these contributions. How should it be shared? We analyze the implications of the axiom of Group Monotonicity: if a group of agents simultaneously decrease their input contributions, not all of them should receive a higher share of output. We show that in combination with other more familiar axioms, this condition pins down a very small class of methods, which we dub nearly serial.

Distribution-Free Bounds for Serial Correlation Coefficients in Heteroskedastic Symmetric Time Series

We consider the problem of testing whether the observations X1, ..., Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed: exponential bounds, Eaton-type bounds, Chebyshev bounds and Berry-Esséen-Zolotarev bounds. The bounds are exact in finite samples, distribution-free and easy to compute. The performance of the bounds is evaluated and compared with traditional serial dependence tests in a simulation experiment. The procedures proposed are applied to U.S. data on interest rates (commercial paper rate).

An Axiomatization of the Serial Cost-Sharing Method

We o¤er an axiomatization of the serial cost-sharing method of Friedman and Moulin (1999). The key property in our axiom system is Group Demand Monotonicity, asking that when a group of agents raise their demands, not all of them should pay less.

Au-delà et à côté de la Quality TV : une alternative esthétique brésilienne

Tout en voulant inclure la fiction télévisuelle brésilienne parmi les fictions de qualité, cette recherche analyse l’émergence et l’évolution du concept de qualité dans le panorama télévisuel brésilien. Examinant l’histoire de la télédramaturgie au Brésil, depuis les téléthéâtres jusqu’aux microséries réalisées par Luiz Fernando Carvalho, en particulier la microsérie Capitu (2008), nous suggérons que la production fictionnelle brésilienne a atteint un niveau de qualité sophistiquée et avant-gardiste qui illustre une alternative au style préconisé par la formule des séries télévisées américaines qui se regroupent sous l’étiquette de la Quality TV. De plus, le raffinement de la microsérie contribue à la légitimation de la valeur artistique de la télévision à partir de caractéristiques télévisuelles, contrairement à la production fictionnelle américaine dont l’esthétique plutôt cinématographique finit par discréditer davantage le petit écran. Finalement, nous souhaitons démontrer l’importance des innovations esthétiques que cette microsérie a apportées au sein d’une sphère médiatique qui semble se diriger progressivement et rapidement vers l’uniformisation du langage télévisuel et de son contenu.

Quantum wire with periodic serial structure

Electron wave motion in a quantum wire with periodic structure is treated by direct solution of the Schrödinger equation as a mode-matching problem. Our method is particularly useful for a wire consisting of several distinct units, where the total transfer matrix for wave propagation is just the product of those for its basic units. It is generally applicable to any linearly connected serial device, and it can be implemented on a small computer. The one-dimensional mesoscopic crystal recently considered by Ulloa, Castaño, and Kirczenow [Phys. Rev. B 41, 12 350 (1990)] is discussed with our method, and is shown to be a strictly one-dimensional problem. Electron motion in the multiple-stub T-shaped potential well considered by Sols et al. [J. Appl. Phys. 66, 3892 (1989)] is also treated. A structure combining features of both of these is investigated

Análisis de la autorregulación, deontología y responsabilidad social en el cubrimiento televisivo del terrorismo. Estudio de caso: cadenas BBC, ALJAZEERA y TVE

Estudio de caso que analiza los códigos de conducta para el cubrimiento televisivo del terrorismo de las cadenas televisivas BBC, TVE y Aljazeera como mecanismos de autorregulación que buscan hacerle frente al fin comunicacional del fenómeno, a través del uso de la responsabilidad social en la labor profesional. Ya que en sistemas políticos que integren la libertad de expresión, la censura de los medios de comunicación por parte del gobierno como política autoritaria que intente frenar la propaganda terrorista no es la solución más efectiva pues pone en riesgo la legitimidad del sistema y genera disconformidades, la autorregulación es la mejor opción. Para el ejercicio de ésta, estas tres cadenas hacen uso de normas internas para modular la narración, tono, imágenes y lenguaje que responden a sus ideales de responsabilidad social, con el fin último de velar por la sensibilidad de las audiencias y hacerle frente al fin comunicacional de los terroristas.

Aprender a ver televisión : estrategias familiares para la apropiación del medio televisivo.

Los contenidos televisivos y los emisores son reprobados y descalificados continuamente. Estas acusaciones tienden a omitir cualquier reflexión acerca del papel de las audiencias, ya que el poder y los efectos que se le atribuyen a la televisión no son ajenos a la manera en que los usuarios deciden ver televisión. Se plantea una revisión crítica de los estudios que abordan específicamente las estrategias de apropiación de la televisión en el ámbito familiar.
