    Belonging to a community: the mediation of belonging
    (OberCom, 2012) Damásio, Manuel José; Henriques, Sara; Costa, Conceição; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    This paper introduces the concept of belonging and discusses it in the context of online social networking experience and community experience considering social capital and user’s activities as nuclear concepts to understand collective actions and social relationships mediated by social media. The paper presents an empirical approach based on the study of two local communities and analyses whether interactive social technologies promote greater social involvement and higher production of social capital and participation, that results in a greater sense of belonging within communities. The results indicate a positive relationship between the use of social media and the increase of social capital and sense of belonging. Our work discusses the role and influence of social media in communitarian practices and the relevance social capital theory has as an outcome of media technologies use that result in a greater sense of belonging to a community.

    Desenvolvimento e Validação da Escala de Literacia Mediática e Informacional para Alunos dos 2º e 3º Ciclos do Ensino Básico em Portugal
    (Edições Universitárias Lusófonas, 2018) Costa, Conceição; Tyner, Kathleen; Rosa, Pedro Joel; Sousa, Carla Patrícia Gonçalves e; Henriques, Sara; Faculdade de Ciências Sociais, Educação e Administração
    A comunicação e a partilha de significados num mundo altamente mediatizado requer múltiplas literacias. Independentemente das definições e abordagens, estas literacias têm vindo a abrir debates críticos sobre quais as competências que os cidadãos devem ter e desde quando elas devem ser adquiridas. No presente estudo damos conta do processo de desenvolvimento e validação de uma Escala de Literacia Mediática e Informacional (ELMI) para alunos dos 2º e 3º ciclos do Ensino Básico em Portugal. A validade de construto foi examinada via Análise Fatorial Exploratória (AFE) para uma amostra de 1151 participantes. A AFE revelou uma estrutura trifatorial constituída por 22 itens que explicam 53.23% da variância total. A escala apresenta uma consistência interna global excelente (ωt = .92), com adequada consistência interna para todas as subescalas (α de Cronbach e α Ordinal > .70). Os resultados evidenciam boas qualidades psicométricas da ELMI que poderá ser um instrumento vantajoso para o prognóstico e avaliação de intervenções relacionadas com a literacia mediática.

    Drivers and barriers to digital television adoption in Portugal: the perspectives of the TV viewers and other main stakeholders
    (Edições Universitárias Lusófonas, 2011) Quico, Célia; Damásio, Manuel José; Henriques, Sara; Veríssimo, Iolanda; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    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.

    Internet móvel em Portugal: variáveis de acesso, uso e consumo
    (2012) Botelho, Inês Teixeira; Henriques, Sara; Damásio, Manuel José; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    A emergência de novas formas de acesso à internet vem reforçar a necessidade de desenvolvimento de iniciativas de I&D que facilitem a melhor compreensão dos processos de transformação associados à evolução tecnológica e aferir se de tais processos resultam novas consequências sociais ao nível das formas de uso e consumo de uma tecnologia e arranjos sociais associados. Este projecto pretende avaliar o papel e relevância das tecnologias móveis de acesso à internet, a importância da mobilidade e dos dispositivos móveis como instrumentos na promoção do envolvimento social, da interação e da expressão subjectiva. Na sequência da aplicação de metodologias qualitativas numa fase exploratória, através de entrevistas com os principais representantes da indústria das comunicações móveis e dos estudos de mercado, e de metodologias quantitativas com a aplicação de um questionário a uma amostra representativa da sociedade portuguesa, temos como objectivo desenvolvimento de um protótipo para uma aplicação móvel no contexto educativo do ensino superior, ligada ao apoio aos alunos e docentes e incluindo conteúdos escolares, institucionais e de envolvimento social. Esta aplicação vem corresponder às necessidades dos utilizadores de acordo com os resultados obtidos anteriormente. A análise do uso desta plataforma e consequências daí resultantes em termos de participação, usabilidade, actividades e potencial para produção de capital será realizada com base na análise de redes sociais (SNA). Através desta pretendemos observar e estudar as relações e os padrões de relacionamentos entre os utilizadores de internet móvel num contexto educativo.

    Mobile Internet : perspectives from the Stakeholders
    (ECREA 2012, 24-27 October – Istanbul, 2012) Damásio, Manuel José; Botelho, Inês Teixeira; Henriques, Sara; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    Mobile internet represents a major new trend in communication technologies use and consumption, but few evidence exists that confirms claims of novelty and social change in association with this technology use. This paper characterizes the use of mobile internet in a southern European country and associated patterns of use, focusing both on users’ profiles, forms of access, motivations to use and most popular activities undertaken via this technology, from a diffusion of innovations and social adoption of technologies perspectives, and tries to compare mobile it with fixed access to the internet in order to validate possible transformations that point to new social configurations. We seek to understand the way stakeholders perceive and characterize the European context of mobile internet. The depicted study involved a qualitative stage consisting of a set of interviews with mobile communications industry representatives and market research community in the country. These interviews were analysed in Nvivo, leading to the following eleven main categories that are explored throughout the paper: smartphones in Europe, mobile internet in Europe, users profiles, obstacles to the spread, forms of access, forms of use, motivations to use mobile internet, limitations of smartphones, apps, digital divide VS digital union and predictions for the future, as well as several subcategories forming a tree categorization. According to the data collected, mobile phones’ sales are decreasing in Europe and worldwide but on the other hand smartphones are having an exponential growth which leads to the democratization of internet access via mobile devices. As a consequence of this, it is believed that mobile internet access will soon exceed the fixed one. Mobile internet users are multiplatform, they exploit all the possibilities of mobility and they are spending less time on computers. The main obstacles to the spread of mobile internet are the high prices of price plans and there is still a lack of information and knowledge regarding the service. Mobile internet users are developing new online surfing behaviours based on apps and less in browsers and social networks represent a very high share of internet traffic through mobile phones. With mobility, “dead time” is turning into useful time and users are more likely to be available to try new services and analyze products. Innovative services concerning geolocation, consumerism, share and relationships are growing and it is necessary to highlight that mobile internet allows calling and texting, which can turn telecommunications companies into the role of Dump Pipes. This exploratory design raises questions in relation with mobile internet access and its social consequences, and provides interesting indicative research results relevant for future research in this area.

    Profiles of digital TV adopters in the switchover context in Portugal
    (Edições Universitárias Lusófonas, 2012) Quico, Célia; Damásio, Manuel José; Henriques, Sara; Veríssimo, Iolanda; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    In order to conduct a successful transition from analogue terrestrial television to full digital terrestrial television it is essential to identify what are the most significant drivers and barriers for adoption among the impacted population. Also importantly, it is to segment the population according with their attitudes towards digital TV, their awareness about the switchover process and intention of adopting digital TV, among other relevant topics. The tradition of profiles definition based on the adoption and rejection of innovations can be traced back to Beal & Bohlen, who proposed five categories of innovation adopters based on the time of adoption, with significant differences in selected personal and social characteristics: the innovators, the early adopters, the early majority, the majority and non-adopters. Later, Rogers would propose similar categories of adopters that became the standard for years to come: the innovators, the early adopters, the early majority, the late majority and the laggards. While helpful, these traditional innovation adopters’ profiles do not totally grasp the complexities of the adoption of an innovation such as digital TV, particularly in mandatory settings. In this paper we will propose a classification of adopters of digital TV in Portugal, based on the results of one of the four empirical studies of the research project ADOPT-DTV, namely, the quantitative inquiry administered to a representative sample of the Portuguese population. The paper will be concluded with a brief discussion of results and the enumeration of the next steps of the research project.

    A relevância do capital social para a experiência de uso da internet: contributos para a análise da relação entre comunidades e redes sociais
    (Edições Universitárias Lusófonas, 2012) Damásio, Manuel José; Henriques, Sara; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    O presente trabalho visa contribuir para uma melhor compreensão do papel do conceito de capital social na explicação da experiência contemporânea de uso da internet e eventuais consequências da mesma. O capital social é um conceito multidimensional que integra a participação cívica, satisfação, confiança e envolvimento social como variáveis centrais e nos ajuda a perceber porque é que a satisfação e sucesso das pessoas está tantas vezes associada ao facto de elas estarem ligadas a mais pessoas.

    Using digital interactive television for the promotion of health and wellness
    (Routledge - Taylor & Francis Group, 2014) Quico, Célia; Damásio, Manuel José; Batista, André; Sequeira, Ágata; Veríssimo, Iolanda; Henriques, Sara; Cardoso, Mário; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    Digital interactive television (iDTV) is often seen as a platform with great potential to deliver health and wellness content and services directly to people. Despite the advantages of e-Health, public engagement with such services is still limited. Our research assumes that health literacy plays a key role on users’ engagement with these kinds of services and we postulate that it is one of the main predictors of users’ attitudes and behaviours towards iDTV health and wellness services. Our main goal was to identify and describe the factors that limit the efficiency of e-Health interventions and the potential depicted in this context by specific technologies – i.e. iDTV. The proposed research design adopts a mix of quantitative and qualitative methods and techniques. The studies were conducted in a southern European country – Portugal – between 2012 and 2013. We found that 51.7% of the respondents showed high probability (þ50%) of having limited health literacy (low literacy) and they are more likely to be men/women with an average age of 49.81, fourth grade or less, belonging to status group D/E and showing less interest and less perception of the utility of e-Health interventions. The groups that depict limited e-Health literacy are also the ones least interested in digital TV services related to health and wellness. Following this, we propose that in order for people to realize the actual benefits of using these applications, it is essential to tailor both content and services in accordance with the depicted level of e-Health literacy.
