A estética da imagem na TV digital

This text reflects on the techniques and the process of image production and its artistic composition to digital television in high defini- tion, whereas the 4:3 and 16:9 formats will exist until shutdown of the analog signal. Within this period, consumers of television programming that have analog receivers will continue to see the images in 4:3 format. That fact determines that the productions in high definition, while capturing images with larger viewing area and have high contrast ratio (>1000:1) must be main- tain the elements of visual storytelling within the smallest area and with the contrast ratio of the analog tv (30:1), at the risk of distorting visually the messages produced by the directors.

Social TV Unesp: proposta de aplicativo em segunda tela com ênfase em modelo de negócios para TV Universitária UNESP

The audiovisual market carefully observes a tendency in television consumption habit: viewers are increasingly watching television content while surfing the internet through mobile devices like tablets, smartphones and laptops. Known as second screen, viewers interact simultaneously across these devices, sharing information about the programming on social networks, seeking additional information about the contents well aired, in addition to being likely to purchase products and services on platforms of mobile-commerce persuaded by the scheduling of programming through commercials. Given this, the aim of this article is to propose and prototyping an application visually in second screen with emphasis on business model with possible application on TV Unesp, where the viewer to interact with the programming through the application is exposed to previously scheduled ads, links to mobile-commerce and posts indicating purchase suggestions.

Gamificação: modelagem de conteúdos para programas e aplicativos educativos no ambiente da TV digital interativa

With the deployment of Digital TV in Brazil, there is a need to foment the development and production of interactive audiovisual quality content, especially for programs that present educational messages from the entertainment concept - defined as Edutertainment. The objective of this study is to propose application of the gamification as a link of communication to encourage and modify user behavior, through a narrative that encourages intrinsic motivation for learning and entertainment in this media. This paper points out that there are few models of screenplays for applications production, particularly educational, with simultaneous interactive applications for television flow or complementary programming content offered. For this reason, a special attention is given to the screenplay, by virtue of inserting in its construction, the elements that make up the mechanics and dynamics of games. As a result, is shown the entry "Gamification-iDTV", which defines these two scenarios, as well as the development of a modeling methodology of a content and process, supported by conceptual maps, wireframes and roadmaps, substantiating the conception and elaboration of screenplay's prototype with elements of gamification for educational programs and its interaction applications.

A TV no ecossistema dos onívoros digitais

A quick setup of the digital environment that occurs in these first decades of the twentyfirst century has involved the use of electronic devices for consume content both at home, at work and on the go (ComScore, 2011). The emergence of this vast multiplatform digital landscape impels to know of individual and complementary use of these devices with ubiquitous nature or not. The widespread adoption of smartphones, tablets and other connected devices via internet makes users / consumers of these devices to feed a diet based on a constant flow of digital content across different platforms. The objective of this paper is to describe the role of television in the context of the Media Ecology which is established by the "digital omnivores" a new group of consumers whose name, according Canavilhas (2013, p.03), "is related with the platforms that consumers use to access the Internet, but also to the type of individual and multiplatform consumption they do.”

Tecnologia disseminando a arte: quais as perspectivas para o futuro da TV Digital?

Digital Television offers a resolution of highdefinition images and the possibility of interaction with the user. There is an estimate that by 2018 all municipalities in Brazil have digital signal availability and thus there will be a wide spread of Ginga. Ginga is a technology developed for digital television, which runs between the operating system and yours applications. However, the extensive use of Smart TVs would invalidate this technology? This article to cast a look on the topic, arousing reflection that effect and seeking bring issues that link the advantages and disadvantages of the two technologies, considering the current situation of Digital TV in Brazil.

Uma mirada em dois projetos e concepções sul-americanas de TV pública digital: análise comparativa entre TV Brasil e Canal 7 Argentina

Esta tesis es resultado de un intenso trabajo de investigación realizado de agosto de 2014 a agosto de 2015, con financiación de la Fundação de Amparo à Pesquisa do Estado de São Paulo (Fapesp). El objetivo se centró en la realización de un análisis, aunque preliminar, del papel de la TV pública con tecnología digital, como también de las tendencias, desafíos y perspectivas para consolidarla, tanto en Brasil como en Argentina, países con diversas similitudes en contextos económicos, sociales, políticos y culturales. Para cumplir los objetivos, estudiamos los recientes proyectos gubernamentales de televisión pública en los dos países suramericanos. El gobierno argentino invirtió en modernización en Canal 7 (antiguo Argentina Televisora Color-ATC), una emisora de casi seis décadas de funcionamiento, que ha sido prácticamente refundada a partir de los investimentos públicos del gobierno nacional argentino, realizados para digitalizar los sistemas de transmisión y de recepción de televisión abierta. El nuevo Canal 7 pasó a servir de cabeza de red del sistema de televisión pública de Argentina. En Brasil, el gobierno creó a fines del 2007, la Empresa Brasil de Comunicación (EBC), estructura administrativa que opera la red de televisión pública de TV Brasil. Ambos proyectos prometen construir y gestionar sistemas nacionales abiertos, modernos y competitivos de TV Pública Digital Abierta (TVPDA). Esta tesis también describe y compara de modo sucinto el desarrollo histórico de la radiodifusión - evidenciando la televisión como una plataforma en permanente disputa comunicacional, política, ideológica, publicitaria, cultural y económica -, tal como los modelos de televisión pública y comercial en cada uno de los dos países analizados (no entiendo la expresión). La estudiante de periodismo pretende confrontar el desarrollo de una estructura nacional de televisión pública iniciada en el...

THE HOUSE OF JOANA DARK: DRAMA AND PRODUCTION

While discussing images of Our Lady and of the mothers and women of the Garden of Flowers (or "Devils' Hole"), a peripheral district of a city in the interior of Sao Paulo state, this paper intends to explore the specificity of dramatic aesthetics. Rather than depend upon the aesthetics of social drama, as discussed in the works of Victor Turner, the present paper deals with a concept of montage that is inspired by the cinema of Sergei Eisenstein in order to illuminate a selection of field notes... and, along with Eisenstein, Julia Kristeva, Walter Benjamin, Michael Taussig and Antonin Artaud. Wit regards to those readers interested in hearing what these women may have to say, caution is suggested, for the words of these women may ring in our ears as the sounds of musket shots

Convergent Adaptations: Bitter Manioc Cultivation Systems in Fertile Anthropogenic Dark Earths and Floodplain Soils in Central Amazonia

Shifting cultivation in the humid tropics is incredibly diverse, yet research tends to focus on one type: long-fallow shifting cultivation. While it is a typical adaptation to the highly-weathered nutrient-poor soils of the Amazonian terra firme, fertile environments in the region offer opportunities for agricultural intensification. We hypothesized that Amazonian people have developed divergent bitter manioc cultivation systems as adaptations to the properties of different soils. We compared bitter manioc cultivation in two nutrient-rich and two nutrient-poor soils, along the middle Madeira River in Central Amazonia. We interviewed 249 farmers in 6 localities, sampled their manioc fields, and carried out genetic analysis of bitter manioc landraces. While cultivation in the two richer soils at different localities was characterized by fast-maturing, low-starch manioc landraces, with shorter cropping periods and shorter fallows, the predominant manioc landraces in these soils were generally not genetically similar. Rather, predominant landraces in each of these two fertile soils have emerged from separate selective trajectories which produced landraces that converged for fast-maturing low-starch traits adapted to intensified swidden systems in fertile soils. This contrasts with the more extensive cultivation systems found in the two poorer soils at different localities, characterized by the prevalence of slow-maturing high-starch landraces, longer cropping periods and longer fallows, typical of previous studies. Farmers plant different assemblages of bitter manioc landraces in different soils and the most popular landraces were shown to exhibit significantly different yields when planted in different soils. Farmers have selected different sets of landraces with different perceived agronomic characteristics, along with different fallow lengths, as adaptations to the specific properties of each agroecological micro-environment. These findings open up new avenues for research and debate concerning the origins, evolution, history and contemporary cultivation of bitter manioc in Amazonia and beyond.

Constraining H-0 in general dark energy models from Sunyaev-Zeldovich/X-ray technique and complementary probes

In accelerating dark energy models, the estimates of the Hubble constant, Ho, from Sunyaev-Zerdovich effect (SZE) and X-ray surface brightness of galaxy clusters may depend on the matter content (Omega(M)), the curvature (Omega(K)) and the equation of state parameter GO. In this article, by using a sample of 25 angular diameter distances of galaxy clusters described by the elliptical beta model obtained through the SZE/X-ray technique, we constrain Ho in the framework of a general ACDM model (arbitrary curvature) and a flat XCDM model with a constant equation of state parameter omega = p(x)/rho(x). In order to avoid the use of priors in the cosmological parameters, we apply a joint analysis involving the baryon acoustic oscillations (BA()) and the (MB Shift Parameter signature. By taking into account the statistical and systematic errors of the SZE/X-ray technique we obtain for nonflat ACDM model H-0 = 74(-4.0)(+5.0) km s(-1) Mpc(-1) (1 sigma) whereas for a fiat universe with constant equation of state parameter we find H-0 = 72(-4.0)(+5.5) km s(-1) Mpc(-1)(1 sigma). By assuming that galaxy clusters are described by a spherical beta model these results change to H-0 = 6(-7.0)(+8.0) and H-0 = 59(-6.0)(+9.0) km s(-1) Mpc(-1)(1 sigma), respectively. The results from elliptical description are in good agreement with independent studies from the Hubble Space Telescope key project and recent estimates based on the Wilkinson Microwave Anisotropy Probe, thereby suggesting that the combination of these three independent phenomena provides an interesting method to constrain the Bubble constant. As an extra bonus, the adoption of the elliptical description is revealed to be a quite realistic assumption. Finally, by comparing these results with a recent determination for a, flat ACDM model using only the SZE/X-ray technique and BAO, we see that the geometry has a very weak influence on H-0 estimates for this combination of data.

Coupled Boltzmann calculation of mixed axion/neutralino cold dark matter production in the early universe

We calculate the relic abundance of mixed axion/neutralino cold dark matter which arises in R-parity conserving supersymmetric (SUSY) models wherein the strong CP problem is solved by the Peccei-Quinn (PQ) mechanism with a concommitant axion/saxion/axino supermultiplet. By numerically solving the coupled Boltzmann equations, we include the combined effects of 1. thermal axino production with cascade decays to a neutralino LSP, 2. thermal saxion production and production via coherent oscillations along with cascade decays and entropy injection, 3. thermal neutralino production and re-annihilation after both axino and saxion decays, 4. gravitino production and decay and 5. axion production both thermally and via oscillations. For SUSY models with too high a standard neutralino thermal abundance, we find the combined effect of SUSY PQ particles is not enough to lower the neutralino abundance down to its measured value, while at the same time respecting bounds on late-decaying neutral particles from BBN. However, models with a standard neutralino underabundance can now be allowed with either neutralino or axion domination of dark matter, and furthermore, these models can allow the PQ breaking scale f(a) to be pushed up into the 10(14) - 10(15) GeV range, which is where it is typically expected to be in string theory models.

The globular cluster kinematics and galaxy dark matter content of NGC 3923

This paper presents further results from our spectroscopic study of the globular cluster (GC) system of the group elliptical NGC 3923. From observations made with the GMOS instrument on the Gemini South Telescope, an additional 50 GC and ultra-compact dwarf (UCD) candidates have been spectroscopically confirmed as members of the NGC 3923 system. When the recessional velocities of these GCs are combined with the 29 GC velocities reported previously, a total sample of 79 GC/UCD velocities is produced. This sample extends to over 6 arcmin (>6 R-e similar to 30 kpc) from the centre of NGC 3923 and is used to study the dynamics of the GC system and the dark matter content of NGC 3923. It is found that the GC system of NGC 3923 displays no appreciable rotation, and that the projected velocity dispersion is constant with radius within the uncertainties. The velocity dispersion profiles of the integrated light and GC system of NGC 3923 are indistinguishable over the region in which they overlap. We find some evidence that the diffuse light and GCs of NGC 3923 have radially biased orbits within similar to 130 arcsec. The application of axisymmetric orbit-based models to the GC and integrated light velocity dispersion profiles demonstrates that a significant increase in the mass-to-light ratio (from M/L-V = 8 to 26) at large galactocentric radii is required to explain this observation. We therefore confirm the presence of a dark matter halo in NGC 3923. We find that dark matter comprises 17.5(-4.5)(+7.3) per cent of the mass within 1 R-e, 41.2(-10.6)(+18.2) per cent within 2 R-e and 75.6(-16.8)(+15.4) per cent within the radius of our last kinematic tracer at 6.9 R-e. The total dynamical mass within this radius is found to be 1.5(-0.25)(+0.4) x 10(12) M-circle dot. In common with other studies of large ellipticals, we find that our derived dynamical mass profile is consistently higher than that derived by X-ray observations, by a factor of around 2.
