O campo da terapia familiar tem se desenvolvido a partir de diferentes contribuições teóricas e epistemológicas. Um dos desenvolvimentos recentes da terapia familiar tem se dado a partir da emergência do movimento construcionista social em ciência, levando, dentre outras mudanças, a uma maior ênfase nos processos de comunicação no contexto terapêutico. Considerando a crescente utilização das contribuições do construcionismo social pelos profissionais brasileiros envolvidos na prática clínica, consideramos relevante compreender como tem se dado essa transmissão de conhecimentos do campo teórico para o campo clínico. Assim, o objetivo deste estudo qualitativo é investigar a difusão do discurso construcionista social entre um grupo de terapeutas familiares brasileiros, focando em como este se constitui em um aporte útil para sua prática clínica. Foram entrevistados 14 terapeutas familiares, do sexo masculino e feminino, psicólogos, cuja atividade profissional atual envolve o trabalho com famílias, e possuem responsabilidade docente em institutos de formação em terapia familiar. As entrevistas foram gravadas em áudio e transcritas literalmente e na íntegra. A análise das informações foi realizada a partir das propostas construcionistas sociais em ciência. Parte do processo de análise e discussão dos resultados foi realizada em conjunto com a Profa. Sheila McNamee, Ph.D., durante um estágio de pesquisa na Universidade de New Hampshire. Na análise das entrevistas, focamos em dois eixos de discussão. Primeiramente, discutimos o que os participantes descrevem como sendo o construcionismo social, evidenciando as principais ideias e conceitos do construcionismo que norteiam sua prática e seu posicionamento como terapeutas. No segundo eixo, discutimos de forma crítica e reflexiva três maneiras distintas pelas quais os participantes aplicam as ideias construcionistas na prática, enfatizando implicações, possibilidades e limites que advêm deste uso. Ao longo de toda discussão dos resultados, articulamos a análise proposta com aspectos da difusão do construcionismo entre os participantes. Concluímos, a partir deste estudo, que a difusão do construcionismo social está atrelada às formas pelas quais os terapeutas atribuem utilidade aos conceitos teóricos descritos na literatura. Além disso, a sensibilidade ao construcionismo social é um aspecto da prática clínica que oferece diferentes formas dos terapeutas relacionarem-se com as abordagens do campo da terapia familiar, trazendo convites à prática da auto-reflexividade por parte dos terapeutas. (FAPESP) / The field of family therapy has been developed based on different theoretical and epistemological contributions. One of the recently developments of family therapy has taken place based on the contributions of the social constructionist movement in science, leading to an emphasis on the communication processes in the therapeutic context. Considering this increasingly expansion of social constructionists ideas among professionals involved in clinical practice, it is important to know how theoretical knowledge has been incorporated into professional midst. The aim of this study is to investigate dissemination forms of social constructionist discourse among a group of family therapists, focusing on how these ideas are a useful contribution for their clinical practice. We interviewed 14 family therapists, men and women, psychologists, who work with family counseling, and are responsible for teaching social constructionism in family therapy training institutes. All interviews were recorded and literally transcribed. The analysis was carried out based on social constructionisms contributions for research practice. Part of this analysis process was developed in partnership with Professor Sheila McNamee, Ph.D., at the University of New Hampshire, during a research internship. We have divided the meanings made with our participants in two major pillars: Firstly, we discuss the participants definition of social construction, highlighting its main ideas and concepts that guide their clinical practice. Secondly, we critically and reflexively discuss three forms by which our participants apply social constructionism in their practice, emphasizing implications, possibilities and constraints that emerge as a consequence. Throughout these discussions, we articulate our analysis with aspects of dissemination of social constructionisms ideas among the participants. We conclude that the propagation of social constructionists ideas is tied to the utility that family therapists attach to the theoretical contributions of social constructionism. Also, the sensitivity to social constructionisms ideas offers the professionals specific forms by which they can relate to other approaches in family therapy practice. In this sense, this study enhances the importance of self-reflexivity as a quotidian practice of the family therapist. (FAPESP)

Esta pesquisa de mestrado se destina a trazer uma reflexão, a partir da proposta de Produção Partilhada do Conhecimento, acerca do encontro entre a diversidade de saberes orais - presente na cultura oral e popular do Brasil -, e as atuais propostas de transformação das pesquisas nas Ciências Humanas. Por meio da História Oral, etnografia e pesquisa participante contextualizamos academicamente como pode acontecer esta parceria para a produção de conhecimento, em diálogo com a história de vida de Mestre Alcides de Lima Tserewaptu e relatos de vivências seus e de parceiras(os) do Centro de Estudos e Aplicação da Capoeira (CEACA), na cidade de São Paulo. A narrativa de sua jornada pela tradição oral e cultura popular em ambientes institucionais de ensino, tais como a Universidade de São Paulo USP e a Escola Municipal de Ensino Fundamental Desembargador Amorim Lima, contando com o congado e a capoeira, manifestações de resistência e luta pela valorização cultura afro-brasileira, proporcionou a análise de possibilidades de caminhos para se pensar a interlocução destes saberes orais com as propostas teóricas nas áreas de história, cultura, antropologia e educação. A antropologia visual foi um dos meios de partilha e registro dos processos da pesquisa (entrevistas, rituais, batizados, reuniões). A prática - já desenvolvida pelo CEACA na produção de material audiovisual -, junto ao reconhecimento de que as tradições das culturas orais não podem ser transpostas para o escrito, garantiram uma colaboração mais coletiva e a legitimação desse método de pesquisa. Um dos resultados do trabalho é um registro audiovisual no qual o Mestre Alcides e algumas pessoas do CEACA colaboraram com a narrativa, inserção de materiais que representam a essência do grupo, seus valores, motivações e práticas em diálogo com as discussões teóricas. / This masters research intends to bring a reflection - from the proposal of Shared Knowledge Production - to the encounter between the diversity of oral knowledge - present in the oral and popular culture of Brazil -, and the current proposals for the transformation of researches in the Human Sciences. Through Oral History, ethnography and participant research, we seek to contextualize academically how this partnership for the production of knowledge, in dialogue with the life history of Mestre Alcides de Lima Tserewaptu, griô, and among the narratives of his experiences and from his partners at Center for the Study and Application of Capoeira (CEACA), in the city of São Paulo. The narrative of his journey through oral tradition and popular culture in educational institutions such as University of São Paulo and School Amorim Lima, counting on the congado and capoeira, manifestations of resistance and struggle for the valorization of Afro- Brazilian culture, provided the analysis of possibilities of ways to think the interlocution of these oral knowledge with theoretical proposals in the areas of history, culture, anthropology and education. Visual anthropology was one of the means of sharing and recording research processes (interviews, rituals, baptisms, meetings). The practice already developed by CEACA in the production of audiovisual material, allied with the recognition that oral traditions of oral cultures can not be transposed into writing, ensured a more collective collaboration and the legitimation of this method of research. One of the results of the work is an audiovisual record in which Mestre Alcides and some people of CEACA collaborated with the narrative, insertion of materials that represent the essence of the group, their values, motivations and practices in dialogue with the theoretical discussions.

Pautou-se pela questão: quais as características epistemológicas da produção deste Programa, com atenção especial a articulação lógica entre técnicas, métodos e teorias utilizados nas pesquisas e os pressupostos gnosiológicos e ontológicos e qual a sua relação com as condições institucionais dessa produção? Foram identificadas e analisadas as tendências temáticas, as formas de tratamentos teórico-metodológicas e as linhas de desenvolvimento dessa produção. Para a compreensão dessa produção foram recuperadas suas relações com as condições históricas, tais como: história da educação física, da pós-graduação no Brasil, políticas nacionais para ciência e tecnologia e histórico do programa onde as pesquisas foram realizadas. Para o registro e análise da produção foi utilizada uma matriz epistemológica que ajudou a reconstituir a lógica interna de cada pesquisa, interrelacionando seus diversos níveis (técnico, metodológico, teórico, epistemológico) e pressupostos (lógico-gnosiológicos e ontológicos). A articulação entre a lógica reconstituída e as condições históricas da produção (método lógico-histórico) permitiu chegar aos resultados, dentre os quais se destacam: a) a maior parte das pesquisas utiliza a abordagem empírico-analítica, seguida pela abordagem fenomenológico-hermenêutica, essas duas abordagens geram uma tensão no campo científico, explicitando uma manifestação interna das 'guerras da ciência' entre as biológicas e as humanas; b) com alguma distância encontra-se a abordagem dialética e recentemente a abordagem pósmoderna, abordagens que apontam perspectivas críticas e anunciam epistemologias alternativas; c) confirma-se a contribuição da investigação epistemológica, ou a pesquisa sobre a pesquisa, que possibilita caracterizar e problematizar a formação de um campo científico específico. Nesse sentido, espera-se que esta pesquisa ofereça um mapeamento e análise da produção de um dos programas de pós-graduação mais produtivos do país e contribua para um processo de auto-reflexão e auto-crítica no campo científico da educação física. / Abstract: This research conducted an epistemological analysis of the production (theses and dissertations) of Post-graduate School of Physical Education at UNICAMP, 1991 to 2088. Was guide by the question: what are the epistemological characteristics of the production of this program, with special attention to logical articulation of techniques, methods and theories in research and epistemological and ontological assumptions and what its relation with the institutional conditions of its production? Were identified and analyzed trends thematic, forms of theoretical and methodological treatments of the developmental lines of production. To understand this production were restored its relation with the historical conditions, such as: history of physical education in Brazil, post-graduate studies in Brazil, national policies for science and technology, history of the program were the research has been done and training of its faculty. For recording and analysis of production was used an organizer instrument called Matrix Epistemological, who helped to reconstruct the internal logic of each survey, interrelating different levels (technical, methodological, theoretical, epistemological) and assumptions (the ontological and epistemological). The logical link between the reconstituted and historical conditions of production (logical-historical method) allowed to get the results, among which were: a) most research uses the empiricalanalytic approach, followed by the phenomenological-hermeneutic approach, these two approaches generate a voltage in the scientific field explaining an internal manifestation of 'science war' between biological and human; b) with some distance is the dialectical approach and recently the postmodern approach, approaches that link the critical perspectives and announce alternative epistemologies; c) confirms the contribution of epistemological inquiry, or research of the research, which enables to characterize and discuss the formation of a specific field. In this sense, it is expected that this research provides a mapping and analyses of production of one of the graduated programs more productive to contribute to a process of self-reflection and self-criticism in the scientific field of physical education. / Doutorado / Doutor em Educação

This study examines the science/policy interactions in global health science and technology governance. It focuses on the institutional design of organizations that sit at the interface of science and policy, conceptualizing them as Boundary Organizations (BOs). The analysis considers how the institutional design of BOs affect boundary-work. The study examines two case studies, UNESCO’s International Bioethics Committee and the WHO’s Strategic Advisory Group of Experts on Immunization. The study examines the ways in which boundary-work is carried out and finds that the concept of a BO demonstrates an institutionalization of science/policy interactions and the analysis of these two cases show that there are different ways that boundary-work is practiced as a function of the design of BOs. / Doctorat en Sciences politiques et sociales / info:eu-repo/semantics/nonPublished

This PhD thesis examines the status of ‘expert knowledge’ in the history of U.S. asymmetric, or ‘counterinsurgency’ (COIN), warfare during the last century. The historical rise of expert influence has so far been neglected in the study of wars within the field of International Relations and the thesis will give us an indication of the importance and utility of expert knowledge. With a specific focus on the campaigns in the Philippines (1899-1902), Vietnam (1954-75) and Iraq (2003-11), the central research question guiding the project is as follows: “What were the conditions for the evolution, the constitution and the use of ‘outside’ expert knowledge in U.S. counterinsurgency campaigns?” The thesis claims that military and academic ‘experts’ had a key role in framing and implementing the problem-sets and solutions to these conflicts. They have, in Iraq in particular, played an important part in developing the campaigns’ ex-post-facto justification of success. Within the framework of organisational knowledge production, this knowledge does not necessarily play an instrumental role for the military. Instead, it can also serve a merely symbolic function, demonstrating to the audience and stakeholders within the political environment that the organisation is willing to solve the problems the insurgents pose, but without any interest in long-term utilisation of the knowledge. This thesis argues that across time, from the beginning of the Philippine-American War in 1898 to the withdrawal of U.S. forces from Iraq in 2011, ‘counterinsurgency’ has developed from a tactical and operational tool, used instrumentally to fight insurgencies, to a strategy or even ‘ideology’ in its own right. Whilst the methods or techniques of counterinsurgency remain basically the same, expert knowledge is increasingly used in modern – that is post-World War II – campaigns to support a politico-strategic narrative.

This thesis focuses on the role and historical development of strategies of experimental domestication in scientific knowledge production, with a particular focus on the function of the laboratory strains known as 'wild types' in the model organism systems of classical genetics, where they play the role of standing in for the 'natural' instance of the species so that variation may be measured. As part of establishing how lab wild types came to assume this role, I have situated them within a much longer historical trajectory that tracks how changes in the manner that European intellectual traditions conceptualised the domestic-wild divide were linked to the development of new forms of scientific domestication and knowledge production. These new developments required that existing domesticating practices be intensified, expanded and analogised in order to better control, capture and comprehend 'wild' nature. My first two chapters introduce the domestic-wild divide by discussing both contemporary and ancient interpretations of it. In my third and fourth chapter, I explore the roots of the knowledge regime of European scientific domestication. I highlight Francis Bacon's campaign to use knowledge of domesticating practices to restore human dominion, before showing how Linnaeus later re-conceptualised the natural economy as an autonomous order and original order, with domestication reinterpreted as an artful transformation of nature requiring human maintenance to prevent reversion to its wild 'natural state'. I identify this idea of the wild as original and the domestic as derivative and artificially maintained as the basis of the original wild type concept. In my fifth chapter, I discuss Darwin's attempt to unite the domestic and wild under common laws of variation and selection, including his argument that reversion was simply a product of a return to ancestral conditions of existence. I observe that Darwin's theory of variation was problematic for the effort to bring wild nature under controlled conditions for study, so in my sixth and seventh chapters discuss how this difficulty was resolved, first by experimental naturalists both before and after Darwin who utilised vivaria and microscopes to bring pieces of nature indoors, and then by Weismann and Galton's sequestration of heredity, which helped persuade scientists that domestication was not in itself a cause of germinal variation. In my eighth and ninth chapter, I detail how sequestration led the early Mendelians de Vries and Bateson to assume that wild types could be brought into the lab from nature and purified into true-breeding strains. I discuss their differing atomist and interactionist perspectives on wild type, with de Vries favouring 'elementary species' as units of nature, whereas Bateson held wild types and mutants to represent normal and abnormal forms of the species respectively. In my last chapter, I cover the replacement of Bateson's interactionist genetics by the reductionist genetics of the Morgan group and argue that this led to a disintegration of wild types into their component genes. I conclude with a discussion of what wild type strains in classical genetics were meant to be representative of, and end by establishing that whilst these strains may not wholly be representative of their species, they are nonetheless useful tools for scientific knowledge production.

This research report has the theme |Knowledge Production Analysis of Graduate Studies in Education of the Federal University of Sergipe, in 2009-2011.| The methodological theory behind this work is the dialectical historical materialism, because we understand that this theory presents a categorical complex that allows radically grasp our problem under study. Our empirical field is the Graduate of the Federal University of Sergipe Center where are the empirical sources that are the dissertations of 2009-2011. To characterize this research is adopted the documentary research, trying to discuss the problem of production of knowledge regarding the methodological theories; this scientific production meets the needs and interests of the working class in favor of a quality education. This study shows how problematic the following question: |How do you have the epistemological trends in the production of knowledge of NPGED / UFS, in line Educator Training from 2009 to 2011?| Faced with this question, share the understanding that science is built by formulating hypotheses that may or may not be proven with the completion of studies. So, we set hypothesis, that there is a significant quantity of dissertations in NPGED / UFS, from 2009 to 2011 in line Educator Training: with knowledge and skills that link to the phenomenological hermeneutics trend. Within the above, were traced the objectives of this work based on the issue and in the event that previously listed are: General Objective: To analyze as epistemologically present the production of knowledge, Postgraduate Diploma in Education, UFS, on Line Training educators in the period 2009-2011. The instrument used to collect and analyze the data was the paradigmatic matrix developed by Prof. ° Gamboa. Then the data were analyzed from the methodological categories, and all contradiction and categories of content, design of science, man and education. The research result shows that the Knowledge Production of the Graduate Center NPGED / UFS, from 2009 to 2011, mostly is grounded by the phenomenological trend - hermeneutics. To this trend, the interpretation and understanding are essential in the need that men have to communicate. So the cognitive interest that guides the phenomenological hermeneuticalinvestigations is communication. / O presente relatório de pesquisa tem como tema Análise da Produção do Conhecimento da Pós-Graduação em Educação da Universidade Federal de Sergipe, no período de 2009-2011. A teoria metodológica que fundamenta esse trabalho é o materialismo histórico dialético, pois se entende que essa teoria apresenta um complexo categorial que permite apreender radicalmente a nossa problemática em estudo. O nosso campo empírico é o Núcleo de Pós-Graduação da Universidade Federal de Sergipe no qual se encontram as fontes empíricas que são as dissertações do período de 2009-2011. Para caracterizar esta investigação adota-se a pesquisa documental, procurando discutir a problemática da produção do conhecimento em relação as teorias metodológicas; esta produção científica atende aos interesses e necessidades da classe trabalhadora em prol de uma formação de qualidade. Este estudo apresenta como problemática a seguinte indagação: Como se apresentam as tendências epistemológicas na produção do conhecimento do NPGED/UFS, na linha Formação de Educadores no período de 2009 a 2011? Diante desta indagação, partilhamos da compreensão de que a ciência é construída através da formulação de hipóteses que podem ou não ser comprovadas com a finalização de estudos. Assim, indicamos como hipótese, que existe um quantitativo significativo de dissertações no NPGED/UFS, no período de 2009 a 2011 na Linha Formação de Educadores: com saberes e competências que apontam para a tendência fenomenológica hermenêutica. Dentro do exposto, foram traçados os objetivos deste trabalho com base na problemática e na hipótese anteriormente elencadas que são: Objetivo Geral: Analisar como se apresentam epistemologicamente a produção do conhecimento, da Pós-Graduação em Educação, da UFS, na Linha Formação de educadores, no período de 2009-2011. O instrumento utilizado para coletar e analisar os dados foi a matriz paradigmática elaborada pelo Prof° Gamboa. Em seguida, os dados foram analisados a partir das categorias metodológicas, totalidade e contradição e das categorias de conteúdo, concepção de ciência, homem e educação. O resultado da pesquisa aponta que a Produção do Conhecimento do Núcleo de Pós-Graduação NPGED/UFS, no período de 2009 a 2011, em sua maioria é embasada pela tendência fenomenológica - hermenêutica. Para essa tendência, a interpretação e a compreensão são indispensáveis dentro da necessidade que os homens têm de se comunicar. Portanto o interesse cognitivo que orienta as investigações fenomenológica-hermenêuticas é o da comunicação.

A pesquisa visa a fazer uma reflexão sobre a produção de hipermídias para a construção do conhecimento científico acadêmico. Para tanto, temos como base a filosofia de Gadamer (2008), que questiona a incontestabilidade da metodologia científica. Segundo ele, para chegarmos a uma inteligência compreensiva não necessitamos de uma imersão no método científico, uma vez que ela já é adquirida pela experiência mundana: na realidade histórica, na experiência, no tempo, na tradição, visão da qual compartilhamos e a qual acreditamos ser possibilitada por processos digitais de produção do conhecimento. Partimos do conceito de ruptura epistemológica (Bachelard, 1996) para desenvolver a noção da ciência no contexto da hipermídia e suas possibilidades de apropriação na difusão, divulgação e produção do conhecimento, dando origem a três categorias explicitadas no capítulo II. Ao nos concentramos na produção do conhecimento em hipermídia analisamos três trabalhos acadêmicos em linguagem hipermidiática: From (Gomes, 2008), LOttocento (Eco, 1999) e Ilha Cabu (Petry, 2010), análises realizadas sob a óptica de três metodologias distintas que visam avaliar níveis de navegabilidade (Landow, 2006), interatividade (Schulmeister, 2001), hibridismo de linguagens (Santaella, 2005) e níveis de conhecimento (Bairon, 2004) sob o viés da produção do conhecimento em hipermídia como possibilidade de abertura hermenêutica entre ciência e senso comum. / The research intends to ponder on the hypermedia production for the construction of scholarly science knowledge. To this end we rely on Gadamers (2008) philosophy , which questions the scientific methods indisputability. According to him, in order to achieve a comprehensive intelligence we do not need a scientific method immersion, once it has already been acquired viamundane experience -- in historical reality, in experience, in time, in tradition --, a view we share and believe may be allowed for digital processes of knowledge production. We depart from the epistemological rupture (Bachelard, 1996) to develop a notion of science in the hypermedia concept and its possibilities for appropriation of diffusion, dissemination and production of knowledge, giving rise to three categories explained in chapter II. We concentrate in knowledge production in hypermedia and we analyze three academicals works made in hypermedia: From (Gomes, 2008), LOttocento (Eco, 1999) and Ilha Cabu (Petry, 2010), conducted under three methodologies that evaluate levels of navegability (Landow, 2006), interaction (Schulmeister, 2001), hybridity (Santaella, 2005) and knowledge levels (Bairon, 2004) under the bias of the knowledge production in hypermedia as a possibility for a hermeneutical opening between science and common sense.

Synthétisés massivement à partir des années 1930, les PCB (polychlorobiphényles) sont de ces substances chimiques dont l’utilisation a été progressivement interdite à l’échelle mondiale pour des raisons sanitaires, après des décennies de production industrielle et d’usages divers aussi bien dans l’industrie que dans des produits de consommation courante dans les bureaux et les maisons. Ils sont décrits depuis la fin des années 1960 comme un polluant omniprésent dans l’environnement, s’accumulant dans les corps des êtres vivants, toxique, « persistant » (qui – où qu’il se trouve – ne se dégrade pas ou peu au fil du temps), et dont on ne sait aujourd’hui encore se débarrasser qu’en l’incinérant à très haute température. Cette famille de molécules a fait l’objet de nombreuses actions politiques dès le début des années 1970 : non seulement la production et l’utilisation de ces substances ont été progressivement interdites mais des dispositifs réglementaires et des filières industrielles ont été développés pour procéder à leur élimination.Cette thèse étudie comment des dommages, des problèmes, des dangers et des risques ont été associés aux PCB et comment tout ceci a été géré. Or, dans cette perspective, la contamination du monde par ces substances apparaît, au fil des cinq dernières décennies, comme un problème récalcitrant : la multiplication de dispositifs techniques et politiques visant à gérer les (potentiels) effets néfastes des PCB n’a pas suffi à éviter que de nouveaux problèmes n’émergent et que certains types de problèmes déjà pris en charge par le passé ne resurgissent.A partir d’archives, d’entretiens semi-directifs et de documents collectés en ligne, cette thèse pose d’abord quelques jalons pour une histoire transnationale de la qualification et de la gestion des enjeux sanitaires et environnementaux liés aux PCB depuis le début de leur production industrielle en 1929. Elle s’intéresse ensuite plus particulièrement à trois "affaires" survenues en France, entre le milieu des années 1980 et aujourd’hui, au cours desquelles les PCB, à partir de problématisations locales, ont suscité l’intervention de différents acteurs, notamment des scientifiques, des associations et des pouvoirs publics. Elle éclaire ainsi les dynamiques scientifiques, techniques, industrielles, sociales et politiques qui, au-delà du consensus au sein de la communauté scientifique sur la persistance biochimique de ces composés, ont fait la récalcitrance politique du "problème PCB" au fil des décennies. / Massively synthesized from the 1930s, PCBs (polychlorinated biphenyls) are among the chemicals whose uses have been progressively banned at the global scale for sanitary reasons, after many decades of industrial production and varied usages in industry as well as in commodities into offices and households. They have been described since the end of the 1960s as an omnipresent pollutant in the environment, accumulating in the bodies of living organisms, toxic, "persistent" (which – wherever it is – does not, or almost not, degrade over time), and which can be eliminated only by incineration at a very high temperature. These chemicals have been the subject of numerous political actions since the early 1970s: not only have the production and use of these substances been progressively banned, but regulatory devices and industrial sectors have been developed to carry their elimination out.This thesis examines how damages, problems, hazards and risks have been associated with PCBs and how all these have been managed. In this perspective, the world contamination by these substances appears, over the last five decades, as a recalcitrant problem: the multiplication of technical and political devices that have aimed at managing the (potential) adverse effects of PCBs have not prevent new problems from arising and certain types of problems already tackled in the past from resurfacing.Based on archives, interviews and documents collected online, this thesis first sets some milestones for a transnational history of the qualification and management of health and environmental issues related to PCBs since the beginning of their industrial production in 1929. It then focuses on three "cases" in France, between the mid-1980s and today, during which PCBs, from local problematization, prompted interventions of different actors, including scientists, associations and public authorities. Thus, it sheds light on scientific, technical, industrial, social and political dynamics that, beyond the consensus in scientific community on the biochemical persistence of these compounds, have made the political recalcitrance of the "PCB problem" over decades.
