abstract: The academic literature on science communication widely acknowledges a problem: science communication between experts and lay audiences is important, but it is not done well. General audience popular science books, however, carry a reputation for clear science communication and are understudied in the academic literature. For this doctoral dissertation, I utilize Sam Harris's The Moral Landscape, a general audience science book on the particularly thorny topic of neuroscientific approaches to morality, as a case-study to explore the possibility of using general audience science books as models for science communication more broadly. I conduct a literary analysis of the text that delimits the scope of its project, its intended audience, and the domains of science to be communicated. I also identify seven literary aspects of the text: three positive aspects that facilitate clarity and four negative aspects that interfere with lay public engagement. I conclude that The Moral Landscape relies on an assumed knowledge base and intuitions of its audience that cannot reasonably be expected of lay audiences; therefore, it cannot properly be construed as popular science communication. It nevertheless contains normative lessons for the broader science project, both in literary aspects to be salvaged and literary aspects and concepts to consciously be avoided and combated. I note that The Moral Landscape's failings can also be taken as an indication that typical descriptions of science communication offer under-detailed taxonomies of both audiences for science communication and the varieties of science communication aimed at those audiences. Future directions of study include rethinking appropriate target audiences for science literacy projects and developing a more discriminating taxonomy of both science communication and lay publics. / Dissertation/Thesis / Ph.D. Biology 2013

Its theme the popular science articles published in the field of history, which treat of the Second Empire Imperial in Brazil and present the reconstruction of the main characters of this period are: From Pedro II and Princess Isabel. This thesis is justified, as popular science articles are organized by a narrative of scientific discovery in modified news event. The news event is guided from the selection of topics through the following categories: Offbeat and Current. Two popular science articles were analyzed that being a magazine published in Adventures in History and the other in the history of the magazine National Library. The overall objective is to contribute to the studies of popular science discourse within the text and speech and specific: 1) To examine the textual construction, through textual sequences that are embedded in popular science article; 2) Analyze the processing of opinionated promoter of ratings in relation to the scientific findings produced by historical research. The results show that: the popular science article is a genre opinionated and his producer, the science writer, is one that produces opinions about the findings derived from the historical science, so that collaborate for the democratization of scientific knowledge. Opinions are built in accordance to company-Journal of interests. Therefore, the opinions produced by science communicators in popular science articles are arranged from facts and arguments of the promoter and are guided by the semantic categories of journalistic news (unusual and current) / Esta tese compreende que os artigos de divulgação científica necessitam de tratamento pela Linguística Textual-Discursiva, complementada pela Análise Crítica do Discurso. Tem por tema os artigos de divulgação científica publicados na área da História, os quais tratam do Segundo Reinado Imperial no Brasil e apresentam a reconstrução dos principais personagens desse período que são: Do Pedro II e a Princesa Isabel. Esta tese se justifica, pois os artigos de divulgação científica são organizados por uma narrativa da descoberta científica modificada em evento noticioso. O evento noticioso é guiado a partir da seleção de temas, por meio das categorias: Inusitado e Atual. Foram analisados dois artigos de divulgação científica que sendo um publicado na revista Aventuras na História e o outro na revista de História da Biblioteca Nacional. O objetivo geral é contribuir com os estudos do discurso de divulgação científica, no âmbito do texto e discurso e, os específicos: 1) Examinar a construção textual, por meio das sequências textuais que se incrustam no artigo de divulgação científica; 2) Analisar o processamento das avaliações opinativas do divulgador, em relação às descobertas científicas produzidas pela pesquisa historiográfica. Os resultados obtidos demonstram que: o artigo de divulgação científica é um gênero textual opinativo e seu produtor, o divulgador científico, é aquele que produz opiniões a respeito das descobertas oriundas da ciência histórica, de modo que colabore para a democratização do saber científico. As opiniões são construídas em conformidade aos interesses da empresa-jornal. Assim sendo, as opiniões produzidas pelos divulgadores científicos nos artigos de divulgação científica são organizadas a partir de fatos e argumentos do divulgador e são guiados pelas categorias semânticas da notícia jornalística (inusitado e atual)

Genetic sex -the apparent fundamental biological cause of the two male and female human varieties- is a 20th century construct. Looking down the microscope, the stained chromosomes are concrete countable entities and lend themselves easily to genetic determinism. As the chromosome composition of a person is generally fixed at the time of conception, when a Y- or X-bearing sperm is united with the X-bearing egg, a person’s genetic sex is taken as permanent and unchanging throughout their life. Drawing upon gender theory as well as science and technology studies this thesis explores how our particular construction of the concept of ‘genetic sex’ relies on four features of biological sex (binary, fixed, spanning nature, and found throughout the body) and in addition proposes one unique feature, inheritance. The empirical research is based on an analysis of popular science books as well as two case studies of how genes relate to sex determination and development. The analysis of the metaphors used in these books and journal articles reveals how now, with genomic efforts to explore gene expression profiles, there is a shift away from seeing genes as having ‘responsibilities’ for determining phenotypes towards seeing them play a role along with other genes in genetic cascades where other factors such as timing can be incorporated. The analysis of genomic features such as imprinting and X-chromosome inactivation also provide evidence that such a change should be recognised. Rather than seeing sex in terms of fixed and static differences and similarities, current research offers new ways of conceptualising similarities and differences as dynamic and responsive to environment. This supports wider understandings of ‘biology’ as relying on the interactions between genetic processes, cellular environment, and tissue environment – in which the social physicality of bodies is important in forming and maintaining a person’s biology and genetic processes. Yet as the historical analysis of the shift between the one sex to two sex model indicates, it remains to be seen whether the social sphere will respond by incorporating this new evidence into the tacit, everyday understandings of sex or seek to maintain the binary and fixed relationship(s) between men and women by governing them as males and females.

Os conhecimentos culturais ao redor do sabão de cinzas foram escolhidos como tema de um instrumento hipermídia visando inseri-los em uma sala de aula de Química de nível médio. A inspiração na etnografia foi a via considerada nessa direção, partindo da hipótese de trabalho para a etnociência proposta por D\'Olne Campos (2000) com ênfase em um guia êmico e de acordo com a \"teia de relações\" presente no discurso das produtoras do sabão de cinzas (FOUCAULT, 1986). O instrumento criado reuniu textos, fotografias, vídeos, vozes e perguntas/atividades para a interpretação dos alunos. A investigação em sala de aula buscou perceber a natureza da instrução baseada na inserção de um modo de conhecer distinto nas aulas e seus diálogos com outros conhecimentos. A base teórica da pesquisa procurou integrar a abordagem sociocultural da ação mediada (WERTSCH, 1997) com algumas perspectivas dos estudos (trans) culturais no ensino de ciências, como a noção de travessias de fronteiras culturais (AIKENHEAD, 1996), o modelo genérico para a compreensão holística do aluno de ciências (COSTA, 1995) e a teoria das visões de mundo aplicada na pesquisa no ensino de ciências (COBERN, 1991, 2000a). Os alunos interagiram com o Hipermídia inicialmente em grupos durante quatro aulas, respondendo ao mesmo com receptividade, curiosidade, interesse, exibindo diferentes trânsitos pela narrativa etnográfica e integrando os seus recursos. Os movimentos interpretativos dos alunos se basearam nos diálogos com os colegas de grupo, em pesquisas usando a internet e livros e mediante entrevistas envolvendo a comunidade, havendo evidências de respostas mais produtivas aos processos de significação por pares simétricos. Os alunos manifestaram duas tendências principais de respostas para as perguntas propostas no Hipermídia: o conhecimento químico e os modos de explicar das produtoras do sabão. Essas tendências foram associadas às visões de mundo de ciência escolar dos alunos, levando-os a se inclinarem na direção da ciência que explica (tendência dos alunos do tipo \"Cientista em Potencial\") ou em direções consideradas como sendo mais fáceis de compreender (caso dos \"Outros Alunos Espertos\"). Alunos com pressuposições emocionais, religiosas e utilitárias mostraram trânsitos mais engajados na direção da ciência popular e menor interesse pelas explicações da ciência escolar. Existiram barreiras na direção dos dois conhecimentos envolvidos destacando-se as de linguagem, mas essas foram sendo vencidas pela maioria dos alunos com o desenvolvimento das aulas, através do trabalho colaborativo e do suporte oferecido. A professora desenvolveu 14 aulas a partir da exploração do Hipermídia pelos alunos e foi necessário oferecer um suporte teórico e material para o trabalho da mesma: um texto sobre o construtivismo contextual e o hipermídia das \'Visões de Mundo\', um segundo instrumento criado para promover a interanimação com as vozes dos alunos. Tal suporte implicou em uma mudança do paradigma normal das aulas de Química, sugerindo uma direção contrária à assimilação dos conteúdos pelos alunos e apontando para a compreensão como práxis vinculada à explicitação dos contextos culturais de significação dos conhecimentos envolvidos. Isso conduziu a uma comparação entre conhecimentos, sugerindo que a tarefa da demarcação é difícil e delicada. A comparação entre linguagens e algumas crenças específicas das produtoras do sabão de cinzas, no entanto, pareceram facilitar essa tarefa. / The cultural knowledge around the ash soap was chosen as the theme of a hypermedia instrument aiming to insert it into a Chemistry classroom in the secondary level of education. The ethnographic inspiration was considered in this way according to the work hypothesis to ethnoscience proposed by D\'Olne Campos (2000) with an emics guide emphasis and by considering the \"web of relations\" of the ash soap makers\' discourse (FOUCAULT, 1986). The instrument designed joined texts, photographs, videos, voices and questions/activities to the students\' interpretation. The enquiry tried to perceive the nature of an instruction based on the insertion of a different way of knowing into the classes and its dialogues with other knowledge. The theoretical support attempted to integrate the sociocultural approach to mediated action (WERTSCH, 1997) with some perspectives from the (cross) cultural studies in science education, as the cultural border crossings approach (AIKENHEAD, 1996), the generic model for holistically understanding the science student (COSTA, 1995) and the world view theory applied to the science education research (COBERN, 1991, 2000a). In the beginning, the students interacted with the hypermedia into groups using four classes, answering to it with receptivity, curiosity, showing interest and different border crossings into the ethnographic narrative. Their interpretative movements were based on the dialogues with pairs, in the research using internet and books and by doing interviews with the community. There was evidence that more symmetric pairs respond in a more productive way on their meaning making processes. The students showed two main trends to answer the questions proposed in the hypermedia: the chemistry knowledge and the knowledge of the ash soap makers. These trends were associated to their school science world view, inclining them into the direction of the science that explains (trend of the \"Potencial Scientist\" students) or towards another direction seen as easier to understand (as was the case of the \"Other Smart Kids\" students). Students with emotional, religious and utilitarian presuppositions showed more engaged border crossings to popular science direction and lesser interest for the school chemistry explanations. There were barriers in the direction of both knowledge, highlighting the language ones, but these were figured out by the majority of the students as the teacher developed the classes, through the collaborative work and by the support offered. The teacher developed 14 classes since the students\' finished the hypermedia exploratory work, using different strategies to teach. It was necessary to offer theoretical and material support for her work: a text about the contextual constructivism and the \'World View\' hypermedia, a second instrument designed to promote the interanimation with the students\' voices. This support led to a change in the usual paradigm of the Chemistry classes, pointing to a contrary movement concerned to the students\' assimilation of the contents and towards the comprehension as praxis bridged to the knowledge contexts of meaning explanation. This guided to a comparative work between the knowledge involved, stating that the demarcation task is difficult and delicate. However, this task seemed to be easier to accomplish by comparing languages and through some specific beliefs of the ash soap makers.

O objetivo desta pesquisa é abordar a expansão da divulgação científica na Internet por um prisma dialógico. O perímetro do corpus da pesquisa engloba os enunciados postados no Facebook pelas revistas Scientific American Brasil, Pesquisa FAPESP e Superinteressante durante quatro meses do primeiro semestre de 2016 (01 de março de 2016 a 30 de junho de 2016). Empregam-se, como base teórico-metodológica, os conceitos elaborados pelo Círculo de Bakhtin, em especial: responsividade, gêneros do discurso, esferas de atividade humana, autor e ideologia. Dessa forma, almeja-se averiguar em que medida a hipertextualidade, os recursos verbo-visuais e a interação com os demais usuários da rede podem influenciar o conteúdo do enunciado publicado nas páginas de divulgação científica no Facebook. Em um segundo momento de análise, o objetivo é verificar a especificidade de determinadas características da divulgação científica nas redes sociais em comparação a outros meios tradicionais de difusão da ciência: televisão, revista, jornal etc. Para responder tais questões, elabora-se de forma sintética a pergunta de pesquisa: De que maneira as revistas de divulgação científica publicam na rede social Facebook e quais são as consequências discursivas, responsivas e dialógicas desse fenômeno? Por fim, observam-se questões relativas aos gêneros, entre as quais, a autoria e o interlocutor presumido. Além de tais fatores, o emprego ou ausência de referências científicas, assim como o uso de hipertextos com acesso a outros sites e blogs são elementos constitutivos da divulgação científica no Facebook. / The aim of this research is to address the growth of popular science on the Internet through a dialogical perspective. The scope of research encompasses the statements posted on Facebook by Scientific American Brasil, Pesquisa FAPESP and Superinteressante during four months in the first half of 2016 (March 01, 2016 to June 30, 2016). The concepts elaborated by the Bakhtin Circle are used as a theoretical-methodological basis, in particular: responsiveness, speech genres, spheres of human activity, author and ideology. In this way, we aim to investigate the extent to which hypertextuality, verbal and visual resources and interaction with other users of the web can influence the content of the posts published in the pages of popular science on Facebook. In a second step of analysis, the aim is to verify the specificity of certain characteristics of popular science in social networks sites compared to other traditional mediums of science communication: television, magazine, newspaper, etc. In order to answer such questions, the research question is elaborated in a synthetic way: Which way do popular science magazines publish on Facebook and which are the discursive, responsive and dialogic consequences of this phenomenon? Finally, there are issues related to genres, including the authorship and the presumed interlocutor. In addition to these factors, the use or absence of scientific references, as well as the use of hypertexts with links to other websites and blogs are key elements of popular science on Facebook.

O Discurso de Divulgação Científica sobre a saúde pública que circula em revistas como a Scientific American atinge um público amplo, que inclui leitores especialistas (cientistas, profissionais de saúde) e não especialistas (que denominamos como leigos). Em detrimento do Discurso Científico, um novo discurso desliza para produzir sentidos que se incorporam e se regulam através de um olhar de autoridade, que é o dos meios de comunicação. Para esta pesquisa, selecionamos um tema sobre a saúde, que afeta a população mundial, a obesidade, discursivizada pela revista Scientific American. A revista pretende, de forma didática, transmitir uma informação, criando para o leitor a ilusão de democratização dos saberes produzidos no meio científico. A simplificação de termos, a repetição de palavras, o silêncio, a heterogeneidade são marcas linguísti cas que buscamos analisar no discurso de divulgação científica, entendido, aqui, como jornalismo científico. Como resultado, podemos dizer que a responsabilidade educacional nos aspectos que tangem à ciência tem dividido espaço com outra esfera, a mídia, que recorta o que lhe interessa de um contexto maior, a ciência, e enxerta em páginas diagramadas e repletas de figuras coloridas que chamam a atenção de crianças, jovens e adultos. O Discurso de Divulgação Científica é imaginado para um efeito-leitor que encontrará, ilusoriamente, a completude do conhecimento sobre o que procura nas páginas da revista, sem questionar os deslizamentos e os apagamentos de sentido provocados pelo jornalista ao migrar do Discurso Científico para o Discurso de Divulgação Científica. / Popular Science Discourse about public health coursing in magazines as Scientific American, reaches a broad audience that includes experts readers (scientists, health professionals) and non-experts (that we called as laymen). Losing from Scientific Discourse, a new discourse slides to produce meanings that are incorporated and controlled by a look of authority, that is media. For this research, we selected a topic about health that affects global population, obesity, in discourse through Scientific American Magazine. The magazine aims, in a \"didactic\" way, to deliver information, creating for the reader an illusion of knowledges democratization of what is produced in scientific community. Simplification of terms, repetition of words, silence, heterogeneity, are linguistic marks that we tried to analyze in popular science discourse, understood here as scientific journalism. As result, we can say that educational responsibility in aspects that concern science has divided its space with another sphere, media, which cuts out what is interesting from a larger context, science, and puts in diagrammed pages with colorful pictures that call the attention of children, youth and adults. Popular Science Discourse is imagined to a reading-effect that will find, deceptively, the completeness of knowledge about what readers search in the pages of the magazine, without questioning slips and wipe off in the meanings caused by journalist when he migrates from Scientific Discourse to Popular Science Discourse.
