O surgimento da Internet provocou uma revolução no que diz respeito a novas formas de interação entre as pessoas, oferecendo experiências de comunicação em tempo real, nos chamados ambientes virtuais. Diante desse cenário, novos gêneros textuais emergem, abrindo caminho para inúmeras possibilidades de análise sob os mais diversos enfoques. Neste trabalho, tomamos por objeto de estudo as conversações digitais, procurando verificar, num primeiro momento, em que medida estas se aproximam ou se distanciam das conversações face a face. Também procuramos, ainda, identificar, descrever e analisar algumas estratégias interacionais inerentes a esse novo gênero, além de observar a manifestação de fenômenos da (des)cortesia verbal entre os interlocutores que utilizam esta forma de comunicação. Buscamos embasamentos na perspectiva da Análise da Conversação e da Sociolinguística Interacional para definir o gênero digital e as estratégias conversacionais do \"texto falado por escrito\" na Internet. O corpus utilizado neste trabalho é formado por conversações digitais advindas do MSN, software de comunicação instantânea da Microsoft Corporation, escolhido devido à sua larga utilização entre pessoas que utilizam a internet para comunicação. Pretendemos, assim, contribuir para o estudo das conversações digitais no âmbito da língua portuguesa, oferecendo uma nova abordagem para o estudo das comunicações mediadas pelo computador. / The emergence of the Internet sparked a revolution regarding to new forms of interaction between people, offering experiences of real-time communication, in the so-called virtual environments. In this scenario, new text genres emerge, opening up new possibilities for analysis from various perspectives. In this work, our study object is the digital conversations, and we try to ascertain, at first, how these conversations are similar, approach or move away from face to face conversations. We seek also to identify, describe and analyze some interactional strategies inherent to this new genre, in addition to observing the manifestation of phenomena of verbal (dis) courtesy between the interlocutors who use this form of communication. Our basements are on the perspective of Conversation Analysis and Interactional Sociolinguistics, where we try to define the genre and digital strategies of conversational \"spoken text written\" on the Internet. The corpus used in this work is composed by digital conversations coming from the MSN instant messenger software from Microsoft Corporation, which was chosen because of its wide usage among people who access the Internet for communications. We intend, therefore, to contribute to the study of digital conversations in the Portuguese language scope, offering a new approach to the study of computer-mediated communications.

O presente trabalho tem como objetivo essencial identificar e caracterizar o fenômeno emergente da expressão cômica gráfica na conversação natural e cotidiana em redes sociais virtuais, especialmente através de mensagens em linguagem híbrida. Nelas, imagens fixas e texto se combinam criativamente por meio de habilidades comunicativas, antes pouco exploradas por parte do usuário comum, como as habilidades de design associadas à expressão do humor, para difundir \"piadas\" sobre assuntos da atualidade entre círculos de amigos e seguidores. As unidades comunicativas, corpus deste trabalho, assumem o comportamento de memes visuais e sua tipificação sob os pontos de vista da sintaxe, semântica e pragmática, conforme proposto por Morris (1985), colaboram no esclarecimento da relação entre seus elementos constitutivos. A popularização de mensagens com tais características indica seu potencial de influência significativa tanto na manutenção e amplificação do \"capital social\" do usuário criador quanto nos novos traços culturais de uma emergente cultura gráfica amadora / The present work has main goal to identify and characterize the emerging phenomenon of graphic comic expression in natural and everyday conversation in virtual social networks, especially through messages in a hybrid language. These still images and text combine creatively through communication skills, previously little explored by the average user, and skills associated with the expression of mood design, to spread \"jokes\" on current affairs among circles of friends and followers. Communicative units, corpus of this work, assume the behavior of visual memes and their classification under the points of view of syntax, semantics and pragmatics, as proposed by Morris (1985), assist in clarifying the relationship between its constituent elements. The popularization of messages with such features indicates its potential to significantly influence on both the maintenance and amplification of \"social capital\" user as creator in the new cultural traits of an emerging culture amateur graphic.

The present thesis explores how interaction is initiated in multi-party meetings in Adobe Connect, 7.0, with a particular focus on how co-presence and mutual availability are established through the preambles of 18 meetings held in Spanish without a moderator. Taking Conversation Analysis (CA) as a methodological point of departure, this thesis comprises four different studies, each of them analyzing a particular phenomenon within the interaction of the preambles in a multimodal environment that allows simultaneous interaction through video, voice and text-chat. The first study (Artículo I) shows how participants solve jointly the issue of availability in a technological environment where being online is not necessarily understood as being available for communicating. The second study (Artículo II) focuses on the beginning of the audiovisual interaction; in particular on how participants check the right functioning of the audiovisual mode. The third study (Artículo III) explores silences within the interaction of the preamble. It shows that the length of gaps and lapses become a significant aspect the preambles and how they are connected to the issue of availability.  Finally, the four study introduces the notion of modal alignment, an interactional phenomenon that systematically appears in the beginnings of the encounters, which seems to be used and understood  as a strategy for the establishment of mutual availability and negotiation of the participation framework. As a whole, this research shows how participants, in order to establish mutual co-presence and availability, adapt to a particular technology in terms of participation management, deploying strategies and conveying successive actions which, as it is the case of the activation of their respective webcams, seem to be understood as predictable within the intricate process of establishing mutual availability before the meeting starts.
