A ‘Big Data’ Approach to Mapping the Australian Twittersphere

This chapter discusses the methodological aspects and empirical findings of a large-scale, funded project investigating public communication through social media in Australia. The project concentrates on Twitter, but we approach it as representative of broader current trends toward the integration of large datasets and computational methods into media and communication studies in general, and social media scholarship in particular. The research discussed in this chapter aims to empirically describe networks of affiliation and interest in the Australian Twittersphere, while reflecting on the methodological implications and imperatives of ‘big data’ in the humanities. Using custom network crawling technology, we have conducted a snowball crawl of Twitter accounts operated by Australian users to identify more than one million users and their follower/followee relationships, and have mapped their interconnections. In itself, the map provides an overview of the major clusters of densely interlinked users, largely centred on shared topics of interest (from politics through arts to sport) and/or sociodemographic factors (geographic origins, age groups). Our map of the Twittersphere is the first of its kind for the Australian part of the global Twitter network, and also provides a first independent and scholarly estimation of the size of the total Australian Twitter population. In combination with our investigation of participation patterns in specific thematic hashtags, the map also enables us to examine which areas of the underlying follower/followee network are activated in the discussion of specific current topics – allowing new insights into the extent to which particular topics and issues are of interest to specialised niches or to the Australian public more broadly. Specifically, we examine the Twittersphere footprint of dedicated political discussion, under the #auspol hashtag, and compare it with the heightened, broader interest in Australian politics during election campaigns, using #ausvotes; we explore the different patterns of Twitter activity across the map for major television events (the popular competitive cooking show #masterchef, the British #royalwedding, and the annual #stateoforigin Rugby League sporting contest); and we investigate the circulation of links to the articles published by a number of major Australian news organisations across the network. Such analysis, which combines the ‘big data’-informed map and a close reading of individual communicative phenomena, makes it possible to trace the dynamic formation and dissolution of issue publics against the backdrop of longer-term network connections, and the circulation of information across these follower/followee links. Such research sheds light on the communicative dynamics of Twitter as a space for mediated social interaction. Our work demonstrates the possibilities inherent in the current ‘computational turn’ (Berry, 2010) in the digital humanities, as well as adding to the development and critical examination of methodologies for dealing with ‘big data’ (boyd and Crawford, 2011). Out tools and methods for doing Twitter research, released under Creative Commons licences through our project Website, provide the basis for replicable and verifiable digital humanities research on the processes of public communication which take place through this important new social network.

Appropriation de la décision collective : évaluation environnementale comme champ d’application de la participation publique au Bénin

En se basant sur le principe organisationnel des deux types d’ensembles politiques rencontrés au Bénin, le but de cette recherche est d’explorer un ou des modèles conjoints, classiques et coutumiers, de participation en vue de promouvoir une démocratie participative plus proche des citoyens. Trois échelons spatiaux ont constitué le terrain de la recherche : l’Afrique, le Bénin centre et les milieux proches des anciennes royautés. La documentation et les données d’observations et d’entrevues ont été analysées par la démarche de théorisation ancrée et l’appréhension des phénomènes socio-spatiaux. Des quatre modèles originaux avec les critères endogènes d’appréciation de la participation mis en évidence et caractérisés dans les cultures du Bénin, deux, Togbésso-Hon-Togbassa et Daŋnou, émergent comme représentatifs des exigences d’une démocratie avec des formes territorialisées de la participation. La mise en perspective de la participation au Bénin avec les États d’Afrique montre une bonne performance qui le fait référencer comme le plus performant pour ses procédures et pratiques et comme source d’inspiration de mise en place des dispositifs participatifs dans le palmarès des grandes démocraties. Ses deux instruments de la décision, l’analyse participative et l’audience publique, restent perfectibles. La première, une innovation intéressante à encadrer, limite la participation à des acteurs choisis selon des critères généralement non énoncés. L’audience publique reste insatisfaisante par son inadéquation à la production de la décision collective et un modèle antinomique de la pensée politique africaine qui vise le consensus dans une démarche inclusive à essence délibérative sous forme de palabre. Fondement de la démocratie participative, la palabre offre le soubassement pour un modèle synergique basé sur les principes de délibération collective, d’offre de l’initiative de la décision au citoyen, de l’invitation aux débats et de l’écoute active (DROIE), d’un dispositif décisionnel flexible et adapté, au centre duquel se trouvent la délibération, le huis clos, la validation populaire et la reddition de compte, le recours et la réparation ainsi que le contrôle de qualité de la décision, essentiels à la gestion, et structurants à l’évaluation environnementale.

Compreensão de professores de matemática sobre números fracionários

Esta pesquisa tem como um dos seus objetivos investigar como os professores de Matemática expressam sua compreensão sobre números fracionários tendo em vista proporcionar ao estudante conhecimento significativo. A partir da revisão da literatura este estudo foi circunscrito em duas vias: uma endógena onde trago as contribuições de Kieren (1976) e Nunes et al (2003) compreendendo números fracionários a partir dos significados parte-todo, número, operador multiplicativo, medida e quociente. Esses significados foram assumidos a partir de Vergnaud (1990) como um conjunto de situações que dão sentido ao conceito de números fracionários. A outra via, exógena, por meio das contribuições da sociologia do conhecimento segundo Fleck (1976) e da Matemática Cultural por Alan Bishop (1990). Essas duas vias foram selecionadas no intuito de responder: Que compreensão os professores de Matemática manifestam ao enfrentarem um conjunto de situações envolvendo números fracionários? Participaram deste estudo vinte e um professores das redes pública e privada com mais de três anos de experiência no sexto ano do Ensino Fundamental. O estudo contou com a aplicação de um teste diagnóstico com no mínimo duas secções para cada participante contendo quinze questões envolvendo os significados de números fracionários. Os dados foram analisados mediante as categorias: invariante operatório, os cinco significados, dinâmica comunicativa. Como resultado foi possível indicar que do ponto de vista endógeno os professores compreendem números fracionários na dependência dos significados parte-todo e operador multiplicativo, e do ponto de vista exógeno o Círculo Exotérico (os professores participantes) não compreende o objeto em questão como metaconceito, diferentemente do Círculo Esotérico (produções acadêmicas), reforçando assim, a dinâmica comunicativa intracoletiva, que não favorece a escola em geral, nem às práticas pedagógicas em particular, o desenvolvimento de valores como abertura para o ensino de Matemática.

PENSAR A CIBERCULTURA AMBIENTALISTA: Comunicação, mobilização e as estratégias discursivas do Greenpeace Brasil

Nossa Tese postula a existência de uma cibercultura ambientalista, própria do movimento ambiental, que conta com uma dinâmica comunicativa caracterizada por estratégias de discurso e mobilização específicas. O movimento ambiental, aqui representado pela organização de espectro internacional Greenpeace, soube se apropriar das ferramentas digitais, difundir a problemática em um cenário de redes sociais digitais, ciberativismo, interatividade e composição de uma esfera pública em rede, que colocamos em debate. Para entender esse panorama realizamos uma ampla discussão teórica, em permanente diálogo com nosso objeto de estudo, abrangendo a trajetória do ambientalismo e seu lugar enquanto movimento social; as tecnologias da sociabilidade, a Internet e suas mídias como espaço de resistência e controle, assinalando a cibercultura como a própria cultura contemporânea, pautada pelas influências tecnológicas. Realizamos entrevistas com voluntários, seguidores, além de responsáveis pela comunicação do Greenpeace que nos permitiram traçar as motivações da participação e confirmar que o engajamento na causa ambiental foi fortemente impulsionado pelas facilidades do ciberespaço. As estratégias discursivas foram desvendadas com as coordenadas metodológicas da Análise do Discurso, focada na identificação do ethos e das cenas de enunciação, com base em um protocolo de análise que formulamos para compreender a maneira de dizer que leva os sujeitos aderirem maciçamente ao discurso ambiental. Na primeira etapa da análise realizamos diagnóstico de perspectiva quantitativa e caráter exploratório para levantar as campanhas/temáticas principais e avaliar a repercussão dos assuntos nas redes sociais digitais e na mídia convencional. Posteriormente, selecionamos os textos das principais campanhas que passaram pela fase qualitativa, que abarcou os itens lexicais, as técnicas argumentativas e os elementos de destacabilidade, além de aspectos externos ao texto linguístico, como fotos, vídeos, cores e cenas predominantes. O discurso na cibercultura ambiental desvela o ethos do amigo, do parceiro, que oscila entre o drama e a agressividade para chamar atenção à causa. Problemas graves como denúncias ambientais são tratados com um ethos lúdico, até mesmo infantil, usando de linguagem coloquial e de códigos da cultura contemporânea desenhos animados, jogos virtuais, belos animais que cantam e dançam que para os nossos olhos revelam uma cenografia esquizofrênica, mas é justamente o que garante o êxito das campanhas.

The atypical bilingual courtroom:an exploratory study of the interactional dynamics in interpreter-mediated trials in Hong Kong

This study investigates the communication process in the atypical bilingual Hong Kong courtroom, where, unlike in most other jurisdictions, interpreting services are routinely provided for the linguistic majority instead of the linguistic minority and the interpreter usually has to work with court actors who share his/her bilingual knowledge. It sets out to explore how the unique nature of the bilingual Hong Kong courtroom impacts on interactional dynamics in communicative process in the courtroom and potentially on the administration of justice, using authentic recordings of nine criminal trials from three court levels, supplemented by a survey administered to court interpreters. It compares the participant roles of different court actors in different court settings, monolingual and bilingual, using Goffman’s (1981) participation framework and Bell’s (1984) audience design as the conceptual framework. It is found that the notion of recipientship in the atypical bilingual Hong Kong courtroom is complicated by the presence of other bilinguals, which inevitably changes the interactional dynamics and impacts on the power of court interpreter as these bilinguals take on more participant roles in the process. The findings of this study show that the power of court actors is realised in the participant role(s) they and the other co-present court actors take on or are capable of playing. The findings also indicate that a change in the participant role of a court actor has an impact on the participation status other actors, which may in turn hamper the administration of justice. It is also found that the notion of power asymmetry in the courtroom has an effect on the footings adopted by the interpreter and thus on his/her neutrality. This thesis identifies training needs and makes recommendations for best practice in the courtroom and for institutional administrative practice.

The Communicative Dimension and Security in Asia-Pacific: A communicative-viewing proposal for reform of the Japanese Intelligence Services

The postwar development of the Intelligence Services in Japan has been based on two contrasting models: the centralized model of the USA and the collegiality of UK, neither of which has been fully developed. This has led to clashes of institutional competencies and poor anticipation of threats towards national security. This problem of opposing models has been partially overcome through two dimensions: externally through the cooperation with the US Intelligence Service under the Treaty of Mutual Cooperation and Security; and internally though the pre-eminence in the national sphere of the Department of Public Safety. However, the emergence of a new global communicative dimension requires that a communicative-viewing remodeling of this dual model is necessary due to the increasing capacity of the individual actors to determine the dynamics of international events. This article examines these challenges for the Intelligence Services of Japan and proposes a reform based on this new global communicative dimension.

Tourism Media Dynamics: Narratives of the Nation-State

With the premise that the tourism promotional video “China, Forever” provides a crucial access to understanding how tourism engages in a wider circle of socio-culture formation, this dissertation research approaches tourism by examining communicative practices initiated by “China, Forever”. In doing so, it seeks to reveal two dialogues – firstly, between the discursive construction of tourism representational language and China’s nation-state ideology; secondly, between interpretations from overseas Chinese audiences and nation-state narratives delivered via the tourism media. In analyzing the first dialogue, this dissertation reveals that the pursuit of collective and monolithic national imagery has caused a representational violence – one that is committed by the nation-state ideology operated through the organization of tourism language. The very representational coercion itself, however, signifies the nature of tourism media as a vehicle mediating the global gaze and China’s self-representation; illuminating the fact that China’s nation-state building is only to be understood as deeply-grounded in the complexity of postcolonial politics. Furthermore, in a dialectic view, such finding consolidates the nature of “China, Forever” as a cultural product that actively exists as a component in the overall social fabric, co-creating a wider circle of culture politics together with other genres of media products; thus, calling for a more comprehensive understanding of tourism media at large. In the second approach, this dissertation seeks to understand how the tourism video “China, Forever” mediates the relationship between tourism narratives of the nation-state and overseas Chinese individuals; thus bridging together tourism media and ongoing life experiences of the audiences chosen. The analysis reveals that audiences’ interpretations heavily concentrate on resisting and fragmenting the hegemonic nation-state language in “China, Forever”. While some interviewees seek to decentralize the nation-state perspective from aspects of aesthetics, representational style, and representational subjects in “China, Forever” by incorporating their individual memories and past experiences, to some others, the over-polished glorification of China in the mediated tourism discourse is only coercive to China’s social realities experienced by the individual interviewees - the disheartening contrasts of poverty and affluence as well as other social inequalities. From the perspective of the audience group, the Chinese scholars and students at the University of Illinois interviewed for this dissertation research constitute a cohort of exiled audiences for the tourism video “China, Forever”. The audiences subject themselves to voluntary interpellation, a process in which they find themselves defending, negotiating, and resisting the nation-state representation of China – even though they are not its intended audience and have had no input into its production. Nevertheless, such process is one of identification, in which viewers articulate a subject position from which to speak of their own experiences, dilemmas and desires. The usefulness of tourism media discourse in mediating the nation-state narratives and the individual experience is amplified.

The interactive dynamics in the university context: the classroom environment

Interpersonal relationships in human communities gained a great value since the begging of mankind, these relationships are constructed on interaction and socialization. The educational context is not exempt of these interactive and communicative processes, and it is specifically in the classroom where they can be found. The classroom can be identified as a physical and a humane space, in which dynamics are developed from the interactions between teachers and students, learning content, learning strategies and the class environment. All of these aspects are presented in the classroom as part of the teaching and learning processes. It is interesting to analyze the classroom environment and the interactive dynamics that are developed in it, regardless of the student’s age, wether in the case of infants, adolescents or adults. In this particular case, we analyze the classroom environment at the university level. Understanding the interactive dynamics that are being developed in the classroom, determine whether or not an environment is appropriate for the teaching and learning processes, which must be considered, if someone chooses an integral and quality of education.
