This essay aims to understand and interrogate the use of Colour Separation Overlay (CSO) as a mode of experimental production and aesthetic innovation in television drama in the 1970s. It sets out to do this by describing, accounting for and evaluating CSO as a production technique, considering the role of key production personnel, and analysing four specific BBC productions. Deploying methodologies of archival research, practitioner interview, and close textual analysis, the essay also delivers a significant reassessment of the role of the producer and designer in the conceptualisation and realisation of small-screen dramatic fiction.

The search for rocky exoplanets plays an important role in our quest for extra-terrestrial life. Here, we discuss the extreme physical properties possible for the first characterised rocky super-Earth, CoRoT-7b (R(pl) = 1.58 +/- 0.10 R(Earth), M(pl) = 6.9 +/- 1.2 M(Earth)). It is extremely close to its star (a = 0.0171 AU = 4.48 R(st)), with its spin and orbital rotation likely synchronised. The comparison of its location in the (M(pl), R(pl)) plane with the predictions of planetary models for different compositions points to an Earth-like composition, even if the error bars of the measured quantities and the partial degeneracy of the models prevent a definitive conclusion. The proximity to its star provides an additional constraint on the model. It implies a high extreme-UV flux and particle wind, and the corresponding efficient erosion of the planetary atmosphere especially for volatile species including water. Consequently, we make the working hypothesis that the planet is rocky with no volatiles in its atmosphere, and derive the physical properties that result. As a consequence, the atmosphere is made of rocky vapours with a very low pressure (P <= 1.5 Pa), no cloud can be sustained, and no thermalisation of the planet is expected. The dayside is very hot (2474 +/- 71 K at the sub-stellar point) while the nightside is very cold (50-75 K). The sub-stellar point is as hot as the tungsten filament of an incandescent bulb, resulting in the melting and distillation of silicate rocks and the formation of a lava ocean. These possible features of CoRoT-7b could be common to many small and hot planets, including the recently discovered Kepler-10b. They define a new class of objects that we propose to name ""Lava-ocean planets"". (C) 2011 Elsevier Inc. All rights reserved.

We investigate the combined influence of quenched randomness and dissipation on a quantum critical point with O(N) order-parameter symmetry. Utilizing a strong-disorder renormalization group, we determine the critical behavior in one space dimension exactly. For super-ohmic dissipation, we find a Kosterlitz-Thouless type transition with conventional (power-law) dynamical scaling. The dynamical critical exponent depends on the spectral density of the dissipative baths. We also discuss the Griffiths singularities, and we determine observables.

This essay examines the persuasive side of language in a speech given by Senator Barack Obama on Super Tuesday in February 2008. It studies how Senator Obama utilizes language to convince and persuade his audience. This is done from an Aristotelian point of view, meaning that the study focuses foremost on how the senator’s word choices relate to Aristotle’s three means of persuasion, ethos, pathos and logos. Those basic guiding principles are relevant to use since Aristotle’s work on the subject of rhetoric is still today one of the most relevant works in that field. The analysis is basically performed through personal observations guided by previous studies, within the frame of Aristotelian rhetoric. The results show how Senator Obama enforces the three means of persuasion through language and how it can be considered persuasive. The study might add to rhetoric studies from a linguistic perspective since it reaches a better understanding of language used in the field of politics, where rhetoric is a prominent component.

Valendo-me das categorias da Economia das trocas simbólicas, propostas por Bourdieu, pretendo desenvolver neste artigo uma breve análise das trocas simbólicas produzidas em um novo ambiente sócio-técnico (a internet) e como ele tornou possível o surgimento de um espaço virtual de coalizões (redes de interagentes). Nesse sentido, torna-se fundamental pensar a complexa integração entre as trocas simbólicas no mundo "off-line" e "on-line" que disputam o acesso à produção, apropriação e distribuição universal de novos tipos de recursos mais ou menos escassos. Procuro analisar,brevemente, a relação entre a promessa de abundância e certos tipos de escassez encontrados no ciberespaço e a colocação de uma questão que considero fundamental: a arquitetura distribuída da rede eliminaria totalmente a necessidade de representação e delegação ou estabeleceria diferentes filtros e modalidades de organização e seleção de porta-vozes em novos tipos de comunidades?
