This thesis examines the historical geography of Scottish natural history societies active during the period 1831-1900. It argues that the work of the societies described and constituted an important set of relations between science and Scottish civil society that has not been investigated hitherto. The institutional practices of natural history, including fieldwork and display, involved encounters between scientific and cultural expectations which were played out in relation to different audiences and in a variety of sites and spaces. A central concern of Scottish associational naturalists was to transpose science into the language of civic pride and progress. At the same time, members of these societies were anxious to maintain epistemic credibility in relation to a scientific culture itself in flux. The task of appealing both to a local public and to a scientific constituency took different forms in different civic and scientific contexts. The thesis attempts to detail this historical geography with reference to the societies' activities of display, fieldwork, publishing and collective scientific endeavour. The work is based on assessment of primary sources, published and unpublished, and a variety of secondary material. The thesis is organised to reflect the features central to the past geographies of Scottish natural history as associational civic science. The first substantive section (Section II, Chapters 2-5) analyses the efforts of society members to persuade local publics of the relevance and the benefits of associational natural history. Fieldwork involved a series of situated negotiations and affiliations between the language and practices of leisure, aesthetic taste, moral improvement and science. Through public events and built spaces natural history was promoted as an expression of civic culture and as a set of practices capable of transforming urban society. At an individual level, supporters of civic science championed an image of the naturalist as public servant and votary of nature, an image that linked scientific conduct to civic identity. The second substantive section (Section III, Chapters 6-7) examines the influence of the meaning and methods of later-nineteenth-century science on the organisation and activities of Scottish natural history societies. Initiatives to standardise the work of local scientific societies are considered alongside the efforts of individual members to secure a scientific reputation. In addition, the changing relations between the research activities of the societies and the emergence and consolidation of scientific disciplines are investigated alongside the maintenance of an inter-disciplinary ethos. In Chapter 7, engagement with evolutionary ideas is examined, uncovering the ways in which Darwinism was deployed to reinforce, and also to modify, an inductivist view of science and to argue for the continuing relevance of associational natural history to local civil society. In conclusion, the thesis reveals the historical geography of nineteenth-century Scottish natural history to be a dynamic narrative of intellectual and institutional activity conducted in different social and scientific spaces, and it suggests that these practices of local science were an important constituent of civic society and, in part, of national natural knowledge in nineteenth-century Scotland.

In this dissertation, I deconstruct the commonly held assumption that the intrauterine device (IUD) is an unsafe and/or obsolete contraceptive method that has been used mostly to impose population control on women in developing countries. Simultaneously, I explore the changing meaning of the device over the last 40 years in varying socio-historical contexts. Capitalizing on the analytical tradition of science and technology studies that regards technology as socially constructed, I analyze the IUD as a technology that transformed through a series of material and discursive negotiations. Negotiations over the IUD took place in multiple layers, most notably in the social and political domains that defined the meaning of the contraceptive technology, but also in the domain of science, in which claims about the device's technical features and its relationship with the biological body were made. This work is divided into the examination of four major domains – global population politics, American contraceptive market, American antiabortion politics, and scientific research – within which the IUD took shape both materially and discursively. The historical development of the scientific research and discourse of IUDs are juxtaposed with the prevailing socio-political background to illustrate the intricate relationship between scientific research of contraceptive technology and the politics of fertility control. The final chapter addresses the agency of IUD users, introducing the ways in which women in developing countries have manipulated the IUD to achieve reproductive self-determination. / Ph. D.

Nous nous fixons pour but, dans cette thèse, de contribuer à la lecture des récits d'Eric Chevillard sous l’angle des savoirs à l’œuvre. Pour ce faire, nous nous intéressons aux questions d’insertion et d’appropriation de discours étrangers dans sa prose narrative et autres écrits. De manière générale, si les questions d’interdisciplinarité ont été abordées via l’étude de quelques-uns de ses romans, cette thèse se consacre à l’œuvre entière en analysant l’importance et la pertinence de ce qu’il conviendrait ici de nommer l’esprit encyclopédique chevillardien. En se servant de l’épistémocritique comme approche générale des liens entre savoirs et discours littéraire, ce travail s’emploie à lire cette relation dialogique qui induit de fait le rapport de l’écrivain à la science, au savoir et à la connaissance. Le but de ce travail est donc de questionner cette inquiétude proprement poétique du savoir. L’examen porte ainsi sur la manière dont le langage poétique et romanesque articule le savoir, le met en œuvre. L’approche encyclopédique permet finalement de constater, chez l’auteur, une continuation de la tendance qui, depuis Flaubert du moins, montre une appropriation « palimpsestique » de discours de savoir. D’autant que, dans les récits étudiés ici, ce rapport au savoir oscille fréquemment entre logique dissertative et réflexivité. / In this thesis, we aim to contribute to the reading of Eric Chevillard's work by analyzing the relationships between science and litterature. In order to do this, we are interested in questions of insertion and appropriation of foreign discourses in his narrative prose and other writings. In general way, if the questions of interdisciplinarity have been studied through the analysis of some of the author’s novels, this thesis is devoted to the entire work by analyzing the importance and relevance of what should be called chevillard’s encyclopaedism. Using epistemic analysis as a general approach to the links between knowledge and literary discourse, this work attempts to read this dialogical relationship which in fact induces the writer’s relation to science and knowledge. The aim of this thesis is therefore to study this properly poetic concern of knowledge. We thus examine the way in which poetic and romantic language articulates knowledge and implements it. Here, the encyclopaedic approach finally reveals readers to see in his work a continuation of the tendency which, since Flaubert at least, shows a "palimpsestic" appropriation of discourse of knowledge. Especially since, in the narratives studied, this relation to knowledge oscillates between dissertative logic and reflexivity.

Over the course of the 1830s and 1840s, a professional scientific and medical community was coming into being. Exclusive membership, limits to the definition of science, and separation of the professional from the popular sphere became important elements in the consolidation of scientific authority. Studies exploring Victorian scientific authority have tended to focus on professional journals and organs of middle-class culture; this thesis takes a new approach in exploring how this authority is reflected and negotiated across the content of the popular mass-market periodicals which provided leisure reading for working- and lower-class men and women. It uses as examples Chambers's Edinburgh Journal, Reynolds's Miscellany and the Family Herald. The readers of these publications were consumers of scientific information, participants in popularised science and beneficiaries and subjects of new research, but were increasingly excluded from the formal processes of developing scientific theory and practice. Examining representations of anatomy and of mesmerism, health advice and theories of class and gender, the thesis argues for an expanded understanding of mass-market periodicals as communicators of scientific ideas, showing how such material widely informs the content of these publications from fiction to jokes to full-length factual articles. However, the role of the periodicals is much wider than simply the transmission of received ideas, and the thesis reveals a plurality of positions with regard to science and medicine within the popular press. The periodicals engage with modern science in complex and varied ways, accepting, modifying and challenging scientific theories and methods from different positions. The form of the periodical is key, presenting multiple sources of knowledge and ways in which readers may be invited to respond. Chambers's broad support for scientific progress is informed by its useful knowledge identity but tempered by its founding editor's own ambivalent relationship to the scientific establishment. The Herald, influenced by both the periodical's commercial character and its editor's adherence to a spiritual, anti-materialist view of existence, is strongly resistant to modern science, while Reynolds's incorporates it alongside other forms of knowledge in its aim to educate, entertain and empower readers from a socialist perspective.

Esta pesquisa tem como objetivo discutir algumas maneiras de compreendermos a educação em Física como uma aprendizagem cultural, no ponto de vista das pesquisas em educação e no ponto de vista dos estudantes, com base em uma investigação da compreensão dos alunos sobre o que é um conhecimento cultural e como este conhecimento pode ser relacionado à Física e à aula de Física. Na área de pesquisa em Educação Científica, trabalhos voltados à relação Ciência, Educação Científica e Cultura ainda são minoritários, entretanto existe um reconhecimento crescente da importância deste tipo de discussão, onde o termo cultura tem ganhado diversos significados. Podemos identificar algumas linhas possíveis de trabalho com questões culturais, como a questão da identidade (Gurgel, 2014), ponte cultura e arte (Zanetic, 2006; Piassi, 2007) e a questão dos diálogos e práticas culturais em sala de aula (Tobin, 2011), sendo que estes possuem distintos embasamentos teóricos e procedimentos práticos em sala de aula. Para o debate entre como os alunos compreendem o conhecimento cultural e a relação das diferentes maneiras de trabalhar com perspectivas culturais no ensino, apresentamos uma discussão sobre uma proposta de entendimento para o conceito de cultura, realizada a partir de uma análise de discussões dos autores Willian Sewell (1999) e Terry Eagleton (2005). Como base metodológica para investigação do entendimento dos estudantes sobre cultura, apresentamos uma discussão sobre identidade cultural, representações sociais e a metodologia de investigação escolar COGEN (diálogo gerado pelo coletivo). A investigação e análise, realizada em uma escola de educação básica da rede pública de ensino, se deu em dois momentos, a utilização de questionários e entrevista em grupo no formato COGEN grupos focais, onde identificamos particularidades na existência de representações distintas para cultura, acessadas independentemente para cada assunto de debate (sala de aula/escola; Física/Ciência), que permitiram uma discussão sobre a importância de levar em consideração a maneira como os estudantes entendem o conceito de cultura e posturas na sala de aula para a eficácia de um ensino de ciências em uma perspectiva cultural. / This research aims to discuss the some of the ways of comprehending education in physics as cultural, from the point of view of educational research and from the point of view of students, based on an investigation of students\' understanding of cultural knowledge and how this knowledge can be related to physics and the physics classroom. In research in science education, investigations focused on Science, Science Education and Culture are still a minority, however there is a growing recognition of the importance of this kind of discussion, where the term culture has got several meanings. We can identify some possible branches of work with cultural subjects such as identity (Gurgel, 2014), bridge between art and culture (Zanetic, 2006; Piassi, 2007) and the matter of dialogue and cultural practices in the classroom (Tobin, 2011), and these works have different theoretical bases and practical procedures in the classroom. For the debate between how students understand cultural knowledge and the different ways of working with cultural perspectives in education, it is presented a discussion of a understanding of the concept of culture, from an analysis of discussions of the authors Willian Sewell (1999) and Terry Eagleton (2005). As a methodological basis for investigation of students\' understanding of culture, it is presented a discussion of cultural identity, social representations and the methodology of educational research COGEN (dialogue generated by the collective). The research conducted in a a school of the public basic education system, and its analysis, took place in two stages, using questionnaires and group interviews in the format of COGEN methodology and focal groups, where we identify peculiarities in the existence of distinct representations for culture, accessed independently for each subject of debate (classroom / school; Physics / Science), which allowed a discussion on the importance of taking into consideration how the students understand the concept of culture and attitudes in the classroom to the effectiveness of teaching science from a cultural perspective.

Com este trabalho desejamos apresentar o campo pós-estruturalista e a visão pósmoderna de ciência não asséptica, entendendo que este posicionamento nos possibilita um olhar mais amplo para o processo de ensino e aprendizagem das cientificidades. Como localizar a ciência na rede complexa de construção do conhecimento e qual a relação e aproximação que se pode fazer destes conhecimentos com os estudos da arte? É possível olhar a ciência através dos óculos das Artes Híbridas? É possível construir o conhecimento posto curricularmente de outra maneira? É possível pensar este currículo como um campo de disputas onde os caminhos da ciência foram “purificados” em busca de uma assepsia idealizada? Destacamos os instrumentos utilizados para a composição de uma oficina híbrida que versa sobre a potência das Artes Híbridas no ensino de Química e a relevância de um professor que entende o seu papel como o de intelectual específico. Versamos ainda sobre a produção de todo material artístico utilizado (fotografia, vídeo, literatura, jornalismo, história, política, filosofia, etc.), e a importância das escolhas dos métodos, dos conteúdos, dos conceitos, das abordagens e da materialidade para este educador específico em suas práticas discursivas. Pensar, ainda, na possibilidade e potência de uma produção híbrida dos participantes da oficina, nos entendimentos de Bruno Latour. Analisar estes escritos narrativos que versem sobre a Química da guerra e suas aproximações possíveis com as artes híbridas, entendendo esta produção como monumentos construídos em um campo discursivo a partir de posições e de possibilidades para além das tradicionais, reconstruindo o nó gordio no emaranhado dos saberes. / This work intends to present the post-structuralism camp and the post-modern view of cience, taking this perspective as a broader understanding of science teaching and learning process. How to locate science in the complex web of knowledge construction and what is its relation to the sudy of Arts? Is it possible to look science through the glasses of Hybrid Arts? Is it possible to construct the school curriculum knowledge in a different way? Is it possible to see the school curriculum as a field of disputes where the paths for science are “purified” for an idealised asepsis? I highlight the used instruments for the composition of an hybrid workshop which discusses the power of Hybrid Arts in the teaching of Chemistry and the importance of a teacher that can see himself/herself as a specific intellectual. I discuss the importance of choosing specific methods, contents, concepts, approaches and materials for the specific educator durig his/her discursive practices. It is also important to think about an hybrid prodution, in Bruno Latour’s view, at the end of the workshop, by the participants. And, finally, to analyse these writings, which have journalistic features and discuss the Chemistry of war and its possible relations to Hybrid Arts. I see this productions as monuments which were built in a discursive field, from non-traditional positions and perspectives, reconstructing the Gordian knot in the knowledge interweaving.
