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.

The Early Prevention of Obesity in CHildren (EPOCH) collaboration : an individual patient data prospective meta-analysis

Background: Efforts to prevent the development of overweight and obesity have increasingly focused early in the life course as we recognise that both metabolic and behavioural patterns are often established within the first few years of life. Randomised controlled trials (RCTs) of interventions are even more powerful when, with forethought, they are synthesised into an individual patient data (IPD) prospective meta-analysis (PMA). An IPD PMA is a unique research design where several trials are identified for inclusion in an analysis before any of the individual trial results become known and the data are provided for each randomised patient. This methodology minimises the publication and selection bias often associated with a retrospective meta-analysis by allowing hypotheses, analysis methods and selection criteria to be specified a priori. Methods/Design: The Early Prevention of Obesity in CHildren (EPOCH) Collaboration was formed in 2009. The main objective of the EPOCH Collaboration is to determine if early intervention for childhood obesity impacts on body mass index (BMI) z scores at age 18-24 months. Additional research questions will focus on whether early intervention has an impact on children’s dietary quality, TV viewing time, duration of breastfeeding and parenting styles. This protocol includes the hypotheses, inclusion criteria and outcome measures to be used in the IPD PMA. The sample size of the combined dataset at final outcome assessment (approximately 1800 infants) will allow greater precision when exploring differences in the effect of early intervention with respect to pre-specified participant- and intervention-level characteristics. Discussion: Finalisation of the data collection procedures and analysis plans will be complete by the end of 2010. Data collection and analysis will occur during 2011-2012 and results should be available by 2013. Trial registration number: ACTRN12610000789066

Video Quality Assessments on Digital TV and Video Streaming Services Using Objective Metrics

There is a wide range of telecommunications services that transmit voice, video and data through complex transmission networks and in some cases, the service has not an acceptable quality level for the end user. In this sense the study of methods for assessing video quality and voice have a very important role. This paper presents a classification scheme, based on different criteria, of the methods and metrics that are being studied in recent years. This paper presents how the video quality is affected by degradation in the transmission channel in two kinds of services: Digital TV (ISDB-TB) due the fading in the air interface and video streaming service on an IP network due packet loss. For Digital TV tests was set up a scenario where the digital TV transmitter is connected to an RF channel emulator, where are inserted different fading models and at the end, the videos are saved in a mobile device. The tests of streaming video were performed in an isolated scenario of IP network, which are scheduled several network conditions, resulting in different qualities of video reception. The video quality assessment is performed using objective assessment methods: PSNR, SSIM and VQM. The results show how the losses in the transmission channel affects the quality of end-user experience on both services studied.

Protocols for Collection, Preservation and Enumeration of Diatoms from Aquatic Habitats fro Water Quality Monitoring in India

Diatoms have become important organisms for monitoring freshwaters and their value has been recognised in Europe, American and African continents. If India is to include diatoms in the current suite of bioindicators, then thorough testing of diatom-based techniques is required. This paper provides guidance on methods through all stages of diatom collection from different habitats from streams and lakes, preparation and examination for the purposes of water quality assessment that can be adapted to most aquatic ecosystems in India.

Evaluation of the Quality of Drinking Water in Kerala State, India

The quality of tap water from water supplies from 14 districts of Kerala state, India was studied. Parameters like pH, water temperature, total dissolved solids, salinity, nitrates, chloride, hardness, magnesium, calcium, sodium, potassium, fluoride, sulphate, phosphates, and coliform bacteria were enumerated. The results showed that all water samples were contaminated by coliform bacteria. About 20% of the tap water samples from Alappuzha and 15% samples from Palakkad district are above desirable limits prescribed by Bureau of Indian Standards. The contamination of the source water (due to lack of community hygiene) and insufficient treatment are the major cause for the coliform contamination in the state. Water samples from Alappuzha and Palakkad have high ionic and fluoride content which could be attributed to the geology of the region. Water supplied for drinking in rural areas are relatively free of any contamination than the water supplied in urban area by municipalities, which may be attributed higher chances of contamination in urban area due to mismanagement of solid and liquid wastes. The study highlights the need for regular bacteriological enumeration along with water quality in addition to setting up decentralised region specific improved treatment system.

Color filter-less technology of LED back light for LCD-TV - art. no. 68410G

Back Light Unit (BLU) and Color Filter are the two key components for the perfect color display of Liquid Crystal Display (LCD) device. LCD can not light actively itself, so a form of illumination, Back Light Unit is needed for its display. The color filter which consists of RGB primary colors, is used to generate three basic colors for LCD display. Traditional CCFL back light source has several disadvantages, while LED back light technology makes LCD obtain quite higher display quality than the CCFL back light. LCD device based on LED back light owns promoted efficiency of display. Moreover it can generate color gamut above 100% of the NTSC specification. Especially, we put forward an idea of Color Filter-Less technology that we design a film which is patterned of red and green emitting phosphors, then make it be excited by a blue light LED panel we fabricate, for its special emitting mechanism, this film can emit RGB basic color, therefore replace the color filter of LCD device. This frame typically benefits for lighting uniformity and provide pretty high light utilization ratio. Also simplifies back light structure thus cut down the expenses.

Plataforma de gestão de guias de programação de TV digital

Com o consumismo de mais variedade e qualidade de informação, assim como, produtos interativos, surgiu a necessidade de apresentar mais conteúdos, para além da programação de televisão comum. Com os avanços tecnológicos ligados à indústria da televisão e sua distribuição nos lares portugueses pelos operadores de TV, a quantidade de oferta de canais deixou de ser um foco, passando a ser prioritário a melhoria da experiência do cliente. Com a introdução de novas funcionalidades nas caixas recetoras de sinais de transmissão de canais, como por exemplo, a capacidade de apresentar informações adicionais sobre os programas, desde da sua apresentação em modo trailer até ao elenco detalhado que o compõe, os clientes podem ter uma nova experiência de interação com os serviços de TV. A funcionalidade de gravação agendada de programas levou ao próximo ponto de melhoria de experiência do cliente. As gravações que resultavam em programas indevidamente cortados, quer no seu início quer no seu fim, foi um dos motivos que levou os operadores de TV a procurarem um melhor serviço de gestão de guias de programação digitais. A InfoPortugal, entidade detentora do seguinte projeto e EPG Provider de algumas operadoras de TV nacionais, viu-se obrigada a atualizar os seu sistemas de distribuição de conteúdos, para responder à evolução dos requisitos dos seus clientes.

Educação a distância - TV escola e PROINFO: impactos em escolas públicas do Estado do Rio de Janeiro

A educação a distância ganha força como mais uma forma de aprendizagem e como um novo recurso de apoio ao trabalho pedagógico. Por essa razão, existe um grande esforço dos governos, no sentido de priorizar as novas formas de aprendizagem a distância. Acompanhar a evolução das políticas públicas de educação a distância, principalmente os impactos percebidos na qualidade do ensino, é o principal objetivo deste estudo. A pesquisa de campo aconteceu em escolas públicas de Niterói, onde foi observada a evolução dos programas da Secretaria de Educação a Distância SEED, bem como os outros aspectos da pesquisa em si. Considerando a atualidade do tema, foi imprescindível, além da revisão na literatura específica e das referencias bibliográficas usuais, fundamentar a argumentação da autora com periódicos e outros conhecimentos pesquisados na internet, através da informação mediada. A dissertação destaca o resultado de toda a investigação e conclui que as novas tecnologias e as formas interativas de aprendizagem ainda não são aceitos pela comunidade escolar, como importantes recursos auxiliares. Os programas TV Escola e Proinfo deveriam revolucionar o modo de capacitação de professores e a aprendizagem dos alunos, mas não estão provocando os resultados desejados, nas escolas observadas. Os objetivos dos programas ainda não foram alcançados e o esforço dos atores governamentais e não governamentais não teve o sucesso desejado.

Ler televisão limites do curso tv na escola e os desafios de hoje em Sergipe

In Reading Television: Limits of the course TV in the School and the Challenges of Today in Sergipe , we had as objective to detect that type of critical reading of the cultural texts produced by the television, professionals of the education of the public net of the basic and average education of the state of Sergipe that all had concluded its 3 (three) modules carries through. We were effectively tutorial of the first edition of this course of extension in the distance and witness some inconsistencies in its application, moment where the instigated investigation appeared: ahead of the current necessity of if understanding with a critical sense, the paper that plays it measured them in orchestration of the globalizado world, that type of critical reading of the audiovisual language is capable to carry through a professional of the education that participated of a course of this nature? Beginning with documental analysys and qualitative metodology we try to analyse in four chapters, since the origins and motivations of this course, to the opinions of 10 (ten) former course students about the approaches of the same thematic subject by two different television new programs, without missing the opinions of the tutors about the conditions in which were made 4 (four) consecutive editions of the course in Sergipe nor the concrete relationships estabilished by the former course students and the audiovisual on their everyday routine both at home and at work. We conclude that the reading made by the former course students is based on common sense and then not satisfactory to the requirements of this task nowadays, and at the same time we point out that the course failed, for it presented severe issues in terms of management and operations in its practical application to distance, by priorizing quantity over quality, by linking itself to a deficient technical structure, by not beholding the diosyncrasies nor the fundamental videos the teachers have access everyday and that it all had direct relation with the attachment of this course to a verticalized policy of technologization of brazilian education.

The relationships between scrotal surface temperature, age and sperm quality in stallions

In horses, spermatogenesis normally occurs at an average intratesticular temperature of 35. °C; therefore, mechanisms for testicular thermoregulation are essential. Measuring the scrotal surface temperature by thermography is one of the methodologies used to evaluate the effectiveness of testicular thermoregulation. The objective of this study was to determine the relationship between the control of scrotal surface temperature and sperm quality in horses of different ages. In total, 24 Quarter Horse stallions were divided into three groups: YS (young stallions), AS (adult stallions) and OS (old stallions). Initially, we calculated the testicular volume (TV) and evaluated various aspects of the semen (sperm kinetics, plasma membrane integrity and sperm morphology) for all the animals. We also evaluated rectal temperature (RT), body surface temperature (BST,) and average scrotal surface temperature in the testicular region (SST) before (M0) and after sun exposure (M1). Differences were observed (p<0.05) between the RT and BST before and after sun exposure in all three groups. However, there were no differences (p>0.05) in the SST values at these two time points, thus demonstrating the efficiency of the mechanisms for testicular thermoregulation. The SST was similar (p>0.05) among all three groups. Based on these results, we conclude that fertile stallions of different age groups are able to maintain SST and measuring the heat radiating from the scrotum using a digital infrared thermographer. We can also conclude that measuring the heat radiating from the scrotum using a digital infrared thermographer is a practical and efficient tool for monitoring SST in horses. © 2013 Elsevier B.V.
