Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This research has as its theme the construction of identity of science in the media. It is justified in the context of mediatization, where the media acquires a central role in constructing representations of reality and of identities which influence the way the subjects represent the social world (SODRÉ, 2002). The central objective is to analyze the construction of identity of science in Galileu magazine by the theoretical and methodological basis of Discourse Analysis. We evaluated the extent to which the publication adopts a monophonic or polyphonic tone according to Bakhtin. The corpus covers six cover reports of Galileu with the subject of health and cognition, selected from April 2010 to July 2011. The analysis is divided into: analysis of the context of discourse production and discourse analysis. The context analysis used an interview with the current managing editor of the magazine as a tool for data collection. The discourse analysis is divided into four steps: 1) identification of speakers and enunciators of the corpus, 2) description of the ideological formations (IFs) of which these views (enunciators) originate themselves and 3) materialization of these IFs in discourse by the localization of discursive formations (DFs) that compose Galileu and 4) analysis of the relation that DFs build between each other in the discourse. The results show the discursivity of Galileu constructed by a confluence of voices and identities of science related to the IFs of modernity and postmodernity. Its discursivity comes as polyphonic in most of the corpus, due to equipollence, plenivalence and immiscible among these voices. Voices from scientific community are shown as plenivalents, while voices from common sense illustrate and support scientific discourse. / Essa pesquisa tem como tema a construção da identidade de ciência na mídia. Ela se justifica no contexto da midiatização, no qual a mídia adquire papel central na construção de representações do real e de identidades, as quais influenciam no modo como os sujeitos sociais representam o mundo (SODRÉ, 2002). O objetivo central consiste em analisar a construção de identidade de ciência na revista Galileu por meio do aporte teórico metodológico da AD. Avaliamos em que medida a publicação adota um tom monofônico ou polifônico segundo Bakhtin. O corpus da pesquisa abrange seis reportagens de capa da revista Galileu com o tema saúde e cognição, selecionadas no período de abril de 2010 a julho de 2011. A análise se divide em: análise do contexto de produção do discurso e análise do discurso. A análise do contexto utilizou uma entrevista com o atual diretor de redação da revista como instrumento de coleta de dados. A análise do discurso está dividida em quatro etapas: 1) a identificação dos locutores e enunciadores no corpus; 2) a descrição das formações ideológicas (FIs) das quais esses pontos de vista (enunciadores) se originam; 3) a materialização dessas FIs no discurso por meio da localização das formações discursivas (FDs) que compõem a Galileu e 4) análise da relação que as FDs constroem entre si no discurso. Os resultados apontam a discursividade de Galileu como construída numa confluência de vozes e identidades de ciência relacionadas às FIs da modernidade e da pósmodernidade. A sua discursividade ocorre como polifônica na maioria do corpus, devido à equipolência, plenivalência e imiscibilidade entre essas vozes. As vozes da comunidade científica mostram-se plenivalentes, enquanto as vozes do senso comum ocorrem em lugar de ilustração e apoio ao discurso científico.

A materiality approach is developed in this thesis in order to understand social-material relationships during the south-east Scottish Iron Age. The focus is on everyday objects, traditionally lesser studied in terms of cosmological value, made of bone and antler, stone, clay/pottery and metal (copper alloy and iron) from the Broxmouth Hillfort assemblage and other excavated Iron Age sites in East Lothian. This study sets out to move away from typology to examine the connections between these materials through their sourcing, affordances (signative and pragmatic), design, manufacture, use and deposition. In addition to the archaeological evidence, a range of analytical methods are employed; including laser scanning confocal microscopy, raman spectroscopy, and residue and isotopic analysis. It becomes evident that the materials studied, despite their predominantly local availability, were invested with meaning in appropriation, making, and were deliberately curated and maintained in use, assembling rich personal biographies. Identities were tied up with making, using and depositing of materials in turn embodying beliefs of fertility, renewal and productivity which were central to Iron Age cosmology, continuing into the Roman Iron Age. These results contribute to our understanding of the construction and practice of society in the Iron Age of Britain, with implications for how we may design our own 21st Century material worlds. It is proposed that social relations in the Iron Age of south-east Scotland were heterarchical.

This study comprises a close reading and textual analysis of The Sentients of Orion, a space opera series by Australian author Marianne de Pierres, with a view to investigating the representations of gender in modern, popular science fiction by women authors. I hypothesise that de Pierres will pose a fictional enquiry into gender, based on the richness of science fiction by women, but that a closer examination of physical and emotional intimacy (both positive and negative) in these ‘less literary works’ will prove de Pierres’ gender enquiry to be superficial and inconsistent in nature. My main approach is a qualitative exploration of selected incidents through the theoretical lenses of feminist literary criticism, gender theory and, where applicable, queer theory. While I draw eclectically on these interpretive paradigms, my approach is most closely aligned with poststructuralist feminism. Proving the first part of my hypothesis, my findings show that de Pierres does pose an enquiry into gender through her portrayal of plot and character. The particular focus on the intimacies involving the heroine, women, men, and alien characters, proves the second part of my hypothesis incorrect as it reveals how de Pierres not only deeply and consistently challenges the heteronormative status quo, questioning dynamics in relationships, gender roles, ageism, sexism and societal stereotypes, but also provides possible alternatives. / English Studies / D.
