Drivers and barriers to digital television adoption in Portugal: the perspectives of the TV viewers and other main stakeholders

To understand what are the most significant factors for digital TV adoption by the Portuguese population in the switchover context is the main goal of the research project here presented. In April 26, 2012, the analogue terrestrial television switchoff is planned to occur in Portugal, according to the schedule published by the national telecommunication regulator Anacom. Digital terrestrial TV was launched in the country in April 2009, making Portugal one of the countries with a more ambitious schedule – or risky, depending on the perspective - for the full transition from analogue to digital terrestrial television. In this paper we will start by presenting the research project’s objectives, theoretical framework and research design. Next, we will present first results of the project focused on the barriers and drivers to digital TV adoption from two of the empirical studies which integrate it, namely, the quantitative inquiry administered to a representative sample of the Portuguese population and interviews with main stakeholders in the area of digital TV in Portugal. The perspectives of the television viewers are compared with other main stakeholders in this process. The paper will be concluded with a brief discussion of these results and a brief enumeration of next steps for the project.

A mídia televisiva e a escola : um olhar sobre a influência de mensagens da TV na vida escolar de adolescentes de Santa Luzia-PB

A presente pesquisa tem como objetivo problematizar e refletir a influência da mídia televisiva no comportamento e na aprendizagem de adolescentes de duas escolas da Zona Urbana de Santa Luzia-PB. A amostra foi selecionada em um universo de oito turmas do 9º ano do ensino fundamental, em 2011. Através de inquéritos por questionários, o estudo apresenta as percepções de 59 estudantes na faixa etária entre 12 e 16 anos de idade e de suas professoras sobre como as informações veiculadas pela mídia televisiva são interpretadas pelos estudantes, quais os efeitos midiáticos no comportamento desses jovens e qual o nível de conscientização da escola frente à aprendizagem paralela proporcionada pela TV. Na análise da pesquisa recorremos a uma abordagem quanti-qualitativa, à análise de conteúdo, que utiliza a unidade de sentido como base de análise. Sob a ótica da interlocução comunicação/educação, o estudo reflete sobre a importância da utilização dos meios de comunicação na escola. Dados teóricos e empíricos comprovaram, assim, que, diante de seu papel significativo na sociedade, a educação atual deve provocar a emancipação do indivíduo tornando-o capaz de atuar como interlocutor crítico dos acontecimentos sociais, de modo a superar todo e qualquer tipo de alienação midiática.

Los medios publicitarios representan en el proceso de comunicación publicitaria los canales a través de los cuales se difunden los mensajes y se contacta con la audiencia de interés o población objetivo1 Es importante realizar un análisis sobre las tendencias de inversión publicitaria que las empresas más importantes en el sector de telefonía móvil del Ecuador (“Movistar”, “Alegro” y “Claro”) han venido realizando durante los años 2007-2008-2009, debido a la gran importancia que tiene para estas empresas el abarcar una amplia cobertura en el mercado Ecuatoriano, por este motivo se presenta un análisis de mercado (oferta, demanda, competidores), tomando en cuenta aspectos como: penetración telefónica, densidad de telefonía móvil, números de abonados por cada operadora, realizando una revisión puntual sobre cada empresa. Además, su importancia se relaciona al hecho de que actualmente estamos viviendo una era en donde el mercado publicitario ecuatoriano empieza a sentir una nueva etapa basada en la integración de medios, entre lo que es medios tradicionales que son los que se analizan en esta tesis y los medios below the line; estos nuevos medios, como las redes sociales o los mensajes de texto de telefonía móvil constituyen un apoyo dentro de una campaña tradicional. Los resultados de esta investigación presentan variables y tendencias numéricas de inversión para realizar un comparativo entre la inversión publicitaria realizada por las tres empresas de telefonía móvil en los años 2007, 2008 y 2009.

Enchufe TV: estéticas de la cotidianidad y marcas del humor

Las redes sociales virtuales se han convertido en una parte indispensable de la vida cotidiana, especialmente de los jóvenes. Estas redes son la plataforma ideal para que personas del mundo entero se mantengan comunicadas, compartan ideas, gustos, pasatiempos, conocimientos, etc. Contenidos científicos, artísticos, familiares llegan a ser conocidos por inmensas cantidades de personas a través de las redes virtuales. Gracias a ellas es posible crear comunidades virtuales entre quienes comparten los mismos intereses. Enchufe TV vio en estas características de las redes sociales el mejor espacio para dar a conocer sus trabajos; desde su primera aparición, en noviembre del 2011, sus videos cortos de estilo cómico han alcanzado gran popularidad, no sólo en Ecuador sino en toda América Latina, ganando miles de seguidores y logrando millones de visualizaciones. Los videos de Enchufe TV narran situaciones que jóvenes ecuatorianos viven diariamente: un viaje en bus para rendir un examen; hacer la tesis; ir al gimnasio; sus relaciones amorosas y filiales; todas abordadas desde el humor. Mediante la exageración, la repetición, la sorpresa y otros recursos, las situaciones cotidianas son convertidas en escenas cómicas y burlescas. En esta tesis se analiza el discurso creado por Enchufe TV sobre el mundo juvenil y el ser joven en contraposición con el mundo adulto. Los sentidos creados –convertidos en referentes para muchos jóvenes ecuatorianos- se sustentan en estereotipos que -como se demostrará en este trabajo-, provienen principalmente del mundo adulto al que pretenden cuestionar.

The use of computer-based learning tools for teaching and clinical purposes: Interactive computing strategy for Iraq

Medical universities and teaching hospitals in Iraq are facing a lack of professional staff due to the ongoing violence that forces them to flee the country. The professionals are now distributed outside the country which reduces the chances for the staff and students to be physically in one place to continue the teaching and limits the efficiency of the consultations in hospitals. A survey was done among students and professional staff in Iraq to find the problems in the learning and clinical systems and how Information and Communication Technology could improve it. The survey has shown that 86% of the participants use the Internet as a learning resource and 25% for clinical purposes while less than 11% of them uses it for collaboration between different institutions. A web-based collaborative tool is proposed to improve the teaching and clinical system. The tool helps the users to collaborate remotely to increase the quality of the learning system as well as it can be used for remote medical consultation in hospitals.

Quantifying the effects of perturbing the physics of an interactive sulfur scheme using an ensemble of GCMs on the climateprediction.net platform

Aerosols from anthropogenic and natural sources have been recognized as having an important impact on the climate system. However, the small size of aerosol particles (ranging from 0.01 to more than 10 μm in diameter) and their influence on solar and terrestrial radiation makes them difficult to represent within the coarse resolution of general circulation models (GCMs) such that small-scale processes, for example, sulfate formation and conversion, need parameterizing. It is the parameterization of emissions, conversion, and deposition and the radiative effects of aerosol particles that causes uncertainty in their representation within GCMs. The aim of this study was to perturb aspects of a sulfur cycle scheme used within a GCM to represent the climatological impacts of sulfate aerosol derived from natural and anthropogenic sulfur sources. It was found that perturbing volcanic SO2 emissions and the scavenging rate of SO2 by precipitation had the largest influence on the sulfate burden. When these parameters were perturbed the sulfate burden ranged from 0.73 to 1.17 TgS for 2050 sulfur emissions (A2 Special Report on Emissions Scenarios (SRES)), comparable with the range in sulfate burden across all the Intergovernmental Panel on Climate Change SRESs. Thus, the results here suggest that the range in sulfate burden due to model uncertainty is comparable with scenario uncertainty. Despite the large range in sulfate burden there was little influence on the climate sensitivity, which had a range of less than 0.5 K across the ensemble. We hypothesize that this small effect was partly associated with high sulfate loadings in the control phase of the experiment.

GODIVA2: interactive visualization of environmental data on the Web

GODIVA2 is a dynamic website that provides visual access to several terabytes of physically distributed, four-dimensional environmental data. It allows users to explore large datasets interactively without the need to install new software or download and understand complex data. Through the use of open international standards, GODIVA2 maintains a high level of interoperability with third-party systems, allowing diverse datasets to be mutually compared. Scientists can use the system to search for features in large datasets and to diagnose the output from numerical simulations and data processing algorithms. Data providers around Europe have adopted GODIVA2 as an INSPIRE-compliant dynamic quick-view system for providing visual access to their data.

Metal bioaccumulation and cellular fractionation in an epigeic earthworm (Lumbricus rubellus): the interactive influences of population exposure histories, site-specific geochemistry and mitochondrial genotype

Subcellular fractionation techniques were used to describe temporal changes (at intervals from T0 to T70 days) in the Pb, Zn and P partitioning profiles of Lumbricus rubellus populations from one calcareous (MDH) and one acidic (MCS) geographically isolated Pb/Zn-mine sites and one reference site (CPF). MDH and MCS individuals were laboratory maintained on their native field soils; CPF worms were exposed to both MDH and MCS soils. Site-specific differences in metal partitioning were found: notably, the putatively metal-adapted populations, MDH and MCS, preferentially partitioned higher proportions of their accumulated tissue metal burdens into insoluble CaPO4-rich organelles compared with naive counterparts, CPF. Thus, it is plausible that efficient metal immobilization is a phenotypic trait characterising metal tolerant ecotypes. Mitochondrial cytochrome oxidase II (COII) genotyping revealed that the populations indigenous to mine and reference soils belong to distinct genetic lineages, differentiated by 13%, with 7 haplotypes within the reference site lineage but fewer (3 and 4, respectively) in the lineage common to the two mine sites. Collectively, these observations raise the possibility that site-related genotype differences could influence the toxico-availability of metals and, thus, represent a potential confounding variable in field-based eco-toxicological assessments.

The impact of an intelligent classroom on pupils' interactive behaviour

Purpose – The purpose of this research is to determine whether new intelligent classrooms will affect the behaviour of children in their new learning environments. Design/methodology/approach – A multi-method study approach was used to carry out the research. Behavioural mapping was used to observe and monitor the classroom environment and analyse usage. Two new classrooms designed by INTEGER (Intelligent and Green) in two different UK schools provided the case studies to determine whether intelligent buildings (learning environments) can enhance learning experiences. Findings – Several factors were observed in the learning environments: mobility, flexibility, use of technology, interactions. Relationships among them were found indicating that the new environments have positive impact on pupils' behaviour. Practical implications – A very useful feedback for the Classrooms of the Future initiative will be provided, which can be used as basis for the School of the Future initiative. Originality/value – The behavioural analysis method described in this study will enable an evaluation of the “Schools of the Future” concept, under children's perspective. Using a real life laboratory gives contribution to the education field by rethinking the classroom environment and the way of teaching.
