Smartphones, a fusion of mobile telephony, the internet and various media, such as a camera and recorder, are boosting transformations in terms of blurring the boundaries, and it is increasingly difficult to delimit public and private, real and virtual environments. Digital social networks are also being favored by this technology, which enhances their functions and intensifies interactive possibilities. Paradoxically to the population increase, through these mediating tools the world seems smaller and the perception of time and space is transformed. The purpose of this research is to identify the relation of the subject with these mediating technologies. In order to do so, we are based on the socio-historical perspective of understanding of reality, based on historical and dialectical materialism, which grasps productions built socio-historically based on concrete materiality, as well as the understanding of life as a contradictory and constant movement, Complex perception of reality, while mutually constituted by the individual and society. In this perspective the focal group technique was used to survey the subjects' speeches. A pilot group was carried out to test the proposed method and, after the necessary adjustments, there was a definitive application with six groups, totaling twenty-eight participants, all PUC-SP undergraduate students from different courses. As a trigger for the dialogue, slides were presented with images related to the subject. The verbalizations were recorded and transcribed to identify the meaning core, which were analyzed and discussed. In the meaning core potential emancipatory fragments as well as traps and risks in this process were verified / Na dinâmica contemporânea a vida cotidiana está atravessada tecnologicamente pela esfera digital. Os smartphones, fusão entre telefonia celular, internet e diversas mídias como, por exemplo, câmera fotográfica e gravador, estão potencializando transformações em termos de borramento entre espaços, sendo que cada vez mais é difícil delimitar os âmbitos público e privado, real e virtual. As redes sociais digitais também estão sendo favorecidas por essa tecnologia, que potencializa suas funções e intensifica possibilidades interativas. Paradoxalmente ao aumento populacional, através dessas ferramentas mediadoras o mundo parece menor e a percepção de tempo e espaço se transforma. A proposta desta pesquisa é identificar a relação do sujeito com essas tecnologias mediadoras. Para tanto, nos baseamos na perspectiva sócio-histórica de compreensão da realidade, fundamentada no materialismo histórico e dialético, que apreende produções construídas sócio-historicamente com base na materialidade concreta, assim como a compreensão da vida como contraditória e em constante movimento, o que possibilita percepção complexa da realidade, mutuamente constituída pelo indivíduo e sociedade. Nessa perspectiva a técnica de grupo focal foi utilizada para o levantamento de discursos dos sujeitos frente a situações que envolvem o uso das redes sociais digitais. Houve a aplicação do procedimento a seis grupos, totalizando vinte e oito participantes, todos estudantes de graduação da PUC-SP de diferentes cursos. Como estímulos disparadores do diálogo foram apresentados slides com imagens referentes ao assunto. As verbalizações foram gravadas e transcritas para identificação dos núcleos de significação, analisados e discutidos. Verificaram-se nos núcleos potencialidades de fragmentos emancipatórios, assim como armadilhas e riscos nesse processo

Among the multimedia content distribution services to the handheld receivers, mobile TV is a popular service. Digital Video Broadcast (DVB) networks have high capacity and coverage to perform a mass multimedia content distribution. The conventional DVB networks are designed to cover fixed receivers, which have a roof antenna. The handheld receivers have different configurations which cause weaker link budgets. Generally, a broadcast system is unidirectional and it does not have a feedback channel to ensure the reception of the data at the receiver side. On the other hand, cellular networks have more reliable bidirectional links with the handheld receivers. Individual multimedia transmission to each handheld receiver generates a huge load in the cellular networks. In the specific example of mobile TV, it is not efficient to regenerate the same transmission load for each handheld receiver. In our thesis work, we consider a cooperation between the broadcast systems and the cellular networks for an efficient multimedia reception at the handheld receivers. We use the cellular network link for the retransmission of the lost packets from a multimedia broadcast data-flow reception. In this work we analyze the coverage for handheld receivers in a single frequency broadcast network. We specifically consider several outdoor and indoor scenarios in a DVB-T2 network. We analyze how a data flow is processed in DVB-T2 and propose a scheme for the identification of packets in the DVB transmission. The core contribution of our thesis work is the proposition of a Real-time Flow Repair (RFR) Service based on cellular network, which repairs any multimedia data-flow to the handheld receivers in real-time. The proposed RFR service is based on a light client-server application protocol, namely Constrained Application Protocol (CoAP). The RFR proposal is also supported by the analysis of the load generated in LTE Radio access network due to RFR service.

Den här studien handlar om konsumenters adoption av fingeravtrycksläsare i mobiltelefoner. Att implementera fingeravtryck som en verifieringsmetod har blivit allt vanligare i mobiltelefoner. Under 2013 lanserades iPhone 5S med fingeravtrycksläsare. Därefter har två företag lanserat teknologin i sina premiumtelefon, Samsung Galaxy S5 och HTC One Max. Det har även blivit möjligt att utföra betalningar genom PayPal med hjälp av teknologin och snart kommer det även att gå att betala på Alibaba.com, vilket är en kinesisk variant av eBay. Utöver det nämnt ovan går det att låsa upp, skydda bilder och meddelanden med sitt fingeravtryck. I och med denna pågående spridning av tekniken anser vi det nödvändigt att studera vad som påverkar konsumenten vid adoption av denna teknik i nämnda kontext. Detta är nödvändigt att undersöka för att bidra med relevant information till företag som är involverade i denna steknik i olika sammanhang, därmed har vi antagit ett företagsperspektiv i vår studie. Studien genomfördes med en kvantitativundersökning, där 207 st. respondenter fick svara på en enkät med attitydbaserade påståenden relaterade till fingeravtrycksläsare. Frågorna i enkäten är baserade på teorier som tidigare har använts i andra studier som behandlar adoption av teknik, t ex mobilhandel, 3G och internetbank etc. De teorier vi har använt oss utav i vår studie är technology acceptance model, diffusion of innovations, the motivational model och self-service technologies. Resultaten från vår undersökning visade att den relativa fördelen, observation, testmöjlighet, användbarhet, bristande förtroende och upplevd risk hade en betydande påverkan på attityden till fingeravtrycksläsare. Den beroende faktorn attityd till fingeravtrycksläsare består av påståendena från motivationsmodellen samt våra attitydpåståenden som är inkluderade i undersökningen. Resultaten ger oss och relevanta företag en bild av vad som behöver arbetas på för att fler konsumenter skall adoptera fingeravtrycksläsare i sin mobiltelefon. Det vill säga att företag bör lägga marknadsföring på användarbarheten och visa upp den relativa fördelen för att övertyga individer att börja använda teknologin. Genom att det blir vanligare att observera fingeravtrycksläsare i vardagen kommer det att påverka adoptionen positivt. Det fanns en faktor som visade en negativ påverkan på adoptionen, denna faktor var individens bristande förtroende och upplevda risk till fingeravtrycksläsare. Med hjälp av den här informationen kan företag se till att införa lönsamma åtgärder, åtgärder som till exempel att marknadsföra samt utveckla teknologin för att därefter visa att det finns en god säkerhet i fingeravtrycksläsare. Detta kan uppnås genom att se till att budskapet finner konsumenterna genom t ex marknadsföring. Genom att implementera åtgärder som eventuellt kan öka graden av konsumenters adoption av fingeravtrycksläsare gynnas både tillverkaren av sensorn och mobiltelefontillverkaren genom en möjlig ökad försäljning. Vi har även inkluderat ett bonusmaterial i vårt arbete bestående av resultat som vi fick efter att ha samkört teorierna ovan som oberoende faktorer och motivationsmodellen som beroende faktor. Motivationsmodellen förklarar situationsengagemang och beståendeengagemang för en produkt. Det visade sig att för att få konsumenten att ha ett bestående engagemang krävs det att den relativa fördelen framhävs och att konsumenterna försäkras om att användning av fingeravtrycksläsare är säkert, detta höjer i sin tur förtroendet för tekniken. / This study is about the consumer adoption of fingerprint readers in cell phones. The implementation of fingerprint verification methods in mobile phones has been increasing. In 2013 iPhone 5S was launched with a fingerprint reader. Since then the two companies have launched the technology in its premium phones, the Samsung Galaxy S5 and HTC One Max. It has also become possible to make payments through PayPal using the technology, and soon it will also be possible to make payments on Alibaba.com, which is a Chinese version of eBay. In addition to the mentioned fields of usage above, it is possible to unlock your cell phone, protect images and messages with your fingerprint. With this current diffusion of this technology, we believe it is necessary to study the factors that influence consumer adoption of this technology in this context. This is necessary to examine in order to provide relevant information to companies involved in this technology in different contexts, thus we have adopted a corporate perspective in our study. The study was a quantitative survey, where a number of 207 respondents were asked to answer a questionnaire with attitude -based claims related to the fingerprint reader. The survey questions are based on theories that have been used in other studies which consider adoption of technologies such as m-commerce, 3G and Internet banking etc. The theories that were used in our study are the technology acceptance model, diffusion of innovation, the motivational model and self-service technologies. The results of our study showed that the relative advantage, observation, testing capability, usability, lack of trust and perceived risk had all a significant impact on the attitude towards fingerprint readers. The dependent factor attitude towards fingerprint readers consists of the assertions of the motivation model and our attitude claims that are included in the survey. The results provide both us and relevant enterprises a picture of what needs to be worked on in order to get more consumers to adopt fingerprint readers on their cell phone. Therefore companies should put marketing on the usability and show the relative advantage to convince people to start using the technology. By becoming more common to observe the fingerprint reader in everyday life, it will affect adoption positively. There was one factor that showed a negative effect on the adoption, this factor was the individual's lack of trust and perceived risk towards the fingerprint reader. By using this information, companies can look at introducing profitable actions, actions such as to promote and develop the technology and then to show that there is a high level of security in the usage of fingerprint readers. This can be achieved by ensuring that the message finds consumers, this can be done by for example marketing. By implementing actions that could potentially increase the rate of consumer adoption of fingerprint readers, it benefits both the manufacturer of the sensor and the mobile phone manufacturer by a possible increase in sales. We have also included a bonus in our work consisting of results we got after we had reconciled the theories above as independent factors and the motivational model as a dependent factor. The motivational model explains the situation of commitment and enduring commitment to a product. It turned out that to get the consumer to have an enduring commitment it requires that the relative advantage is emphasized and that consumers are assured that the use of fingerprint readers is safe. This in turn enhances confidence in the technology.

CAPES / Com o objetivo de identificar elementos que justifiquem o uso didático dos telefones inteligentes (Smartphones), realizamos uma pesquisa qualitativa investigando a tendência do mobile learning, m-learning visto que há escassez de estudos focados exclusivamente a respeito do uso do celular como ferramenta didática. Resgatando pesquisas sobre o tema em diferentes áreas do conhecimento, esta pesquisa aborda o uso do aparelho celular inteligente no ensino da Matemática empregando o aplicativo WhatsApp. Desenvolvemos, portanto, uma pesquisa bibliográfica onde destacamos como, atualmente, é vista a presença do celular em sala de aula, a relação professor-aluno-celular, e ainda, o smartphone como tecnologia em sala de aula. Como trabalho de campo, acompanhamos dois grupos WhatsApp compostos por alunos do terceiro ano do Ensino Médio que utilizaram o aparelho como ferramenta de estudo de Matemática. Diante disso, observamos que o telefone celular pode ser um aliado de grande potencial para atender as demandas educacionais atuais. Este aparelho, com suas potencialidades, pode se tornar uma ferramenta pedagógica muito poderosa para um ensino que recentemente vem se instalando, conhecido como ensino híbrido, pois, com este aparelho é possível que o aluno acesse plataformas, como Moodle, ou Helpousts, que podem ser utilizadas nesse modelo de ensino e que se mostram como o caminho que a educação vai seguir nos próximos anos. Experiências vivenciadas por professores nas escolas brasileiras, com os telefones inteligentes, também foram analisadas. Diante de vários estudos realizados e dos grupos que acompanhamos, concluímos que o uso pedagógico do celular inteligente tem potencial para revolucionar a comunicação entre professor e alunos bem como proporcionar diferentes abordagens sobre os conteúdos. No entanto, ainda observamos nos docentes uma resistência à presença desse instrumento em sala de aula para fins pedagógicos. / With the objective of identifying elements that justify the didactic use of telephone intelligent (Smartphones), we conducted a qualitative research investigating the trend of mobile learning, m-learning is seen that there is a shortage of studies focused exclusively on the use of the mobile phone as a teaching tool. Rescuing research on the theme in different areas of knowledge, this research discusses the use of cell phone device smart on the teaching of Mathematics by employing the application WhatsApp. We developed, therefore, a bibliographic search where we highlight how, currently, is seen the presence of mobile in the classroom, relation the teacher - student - cell phone, and still, the smartphone as technology in the classroom. As field work , we followed two groups WhatsApp compounds, by students of the third year of high School that have used the instrument as a tool for the study of Mathematics. On the face of it, we observe that the mobile phone can be an ally of great potential to meet the demands of the educational current. This device, with its potential, can become a pedagogical tool very powerful for a school that recently has been installing, known as Hybrid Education, because, with this device it is possible for the student have access platforms, such as Moodle, or Helpousts, which can be used in this model of education and that show it as the path that education will follow in the next few years. Experiences by teachers in Brazilian schools, with telephone intelligent, were also analyzed. In the face of several studies and groups who follow, we conclude that the use of pedagogical smart phone has the potential to revolutionize the communication between teacher and students as well as provide different approaches about the contents. However, we also observed in teachers a resistance to the presence of this instrument in the classroom for teaching purposes.

I arbetet undersöks, utifrån ett telekrigperspektiv med inriktning från ett signalspaningshot, riskerna med nyttjandet av smarta mobiltelefoner i svenska markförband. Undersökningen baseras på ett fiktivt scenario i en nationell kontext och utgår ifrån två aktörer där ena aktören nyttjar smarta mobiltelefoner och andra aktören nyttjar högteknologiska telekrigsystem för att exploatera dess risker. Utifrån, i arbetet framtagna riskindikatorer, skapas olika händelseutvecklingar vilka undersöks utifrån en kvalitativ metod med inslag av kvantitativa beräkningar. Resultatet påvisar att smarta mobiltelefoner, nyttjade inom ramen för svenska markförband, riskerar utsätta såväl individer som hela förband för risker. Riskerna vilka undersöks är avlyssning, lägesbestämning och avslöjande av information genom mobiltelefonernas GNSS-förmåga och geotaggningsfunktioner. Användning av smarta mobiltelefoner riskerar således oavsiktligt röja information varför nyttjandet kräver förståelse för de risker dessa genererar. Riskerna kan inte undvikas varför nyttan med smarta mobiltelefoner måste vägas mot risken i varje situation. / In this thesis, the risks of smartphones in Swedish land forces are analysed from anElectronic Warfare perspective, focusing on Signals Intelligence. The analysis is based on a fictitious scenario in a national context involving two differentactors. One actor uses smartphones and the other actor uses high technology ElectronicWarfare systems to exploit the phones. Based on risk indicators developed in the thesis, twodifferent cases are created, which are then analysed using a qualitative method with elementsof quantitative calculations. The results reveal that smartphones, used in Swedish land forces, put both individuals andunits at risk. The risks, analysed, are interception, location and revealing information fromthe phone’s Global Navigation Satellite System geotagging and functions. Therefore, the useof smartphones might unintentionally reveal information. Consequently, the use ofsmartphones requires an understanding of the risks generated. It is not possible to avoid risks,so the benefit of using smartphones must be weighed against the risk in each situation.

The ways people go online have been transformed by the emergence of new mobile Internet technologies. As modes of Internet access are becoming increasingly diverse, this thesis sets out to examine how various forms of access shape engagement with online resources. Inequalities in Internet access have been neglected in the "second-level digital divide" research, which has focused on differences in skills and usage. Thus, I argue that inequalities of access have to be revisited and their role in digital inclusion reassessed. To study individuals' arrangements of Internet-enabled devices and locations holistically and as a dynamic entity, access is conceptualised as infrastructure. Theoretically, I distinguish between material dimensions of access and social practices shaping access, and draw on existing models of digital inclusion to examine the role of these dimensions and practices in online engagement. Empirically, a mixed methods research design is employed, complementing longitudinal analyses of survey data representative of the British population with 29 qualitative interviews with British Internet users. This study contributes to our understanding of material and social dimensions of access and their impact on Internet use patterns. First, the conceptualisation of Internet access as infrastructure is empirically validated. Second, quality, locality and ubiquity are established as material dimensions of access, where offline social and economic resources most strongly affect inclusion in high-quality, multi-local and ubiquitous Internet access. Third, three specific practices encompassing how users develop and maintain their access infrastructures are identified: spotlighting, distributing and being stranded. They reflect differences in roles Internet technologies play in individuals' daily lives as well as differences in availability of offline resources. Fourth, the results show that, controlling for a range of digital inclusion factors, the access inequalities have significant effects on a range of online engagement types, but are most strongly related to commercial and communication uses of the Internet. In sum, this study provides a nuanced understanding of how different mechanisms underlie the development, maintenance and engagement with Internet access, depending on whether access arrangements are shaped by digital exclusion or choice. Specifically, by outlining critical differences among all-round, mobile-mostly, mobile-only and home-only Internet users, broader policy and research implications are also discussed.
