Frames und Argumentation Integrative Beschreibung semantischer und argumentativer Bedeutungsstrukturen am Beispiel des parlamentarischen Kernenergiediskurses in Deutschland und Frankreich / Semantic frames and argumentation : towards an integrated description of lexical and argumentative meaning structures mean-ing in French and German parliamentary discourse on nuclear energy / Cadres sémantiques et argumentation : description intégrée de structures sémantiques et argumentatives dans les discours parlementaires sur le nucléaire civil en France et en Allemagne

Varga, Simon 07 June 2019 (has links)
La sémantique des cadres et l’analyse argumentative comptent parmi les approches les plus sollicitées en linguistique du discours. De nombreuses études parues ces dernières années font ainsi appel aux cadres sémantiques pour analyser la dimension lexicale des discours et aux topoï argumentatifs pour analyser leur dimension argumentative. Or, cette simple addition de différentes techniques d’analyse est contradictoire avec les prémisses même de la sémantique des cadres. En effet, plus encore qu’un outil d’analyse sémantique, les cadres sémantiques sont un format de représentation cognitive structurant nos connaissances ainsi que notre perception du monde. Par conséquent, les cadres sémantiques permettent, en principe, de décrire l’intégralité des structures de savoir sous-jacentes aux discours, et ceci à tous les niveaux d’abstraction. L’intégration des dimensions de sens ici analysées passe par l’intégration du concept de relation argumentative dans la méthodologie communément appliquée en analyse des cadres. Les structures argumentatives reposant nécessairement sur des structures conceptuelles analogues, l’outil méthodologique ainsi développé permet une description intégrée de ces différentes dimensions et de leur interaction dans la construction discursive du sens. Dans la partie empirique, il sera ensuite appliqué à l’analyse des discours parlementaires sur le nucléaire civil à l’Assemblée nationale française et au Bundestag allemand sur la période 1946–2012. / Frame semantics and argumentation analysis are among the most popular research methodologies in discourse linguistics. Over the course of the last few years, semantic frames and argumentative topoi have been used in numerous studies to analyse the lexical and argumentative dimension of discourse. However, their simple addition contradicts one of the most basic premises of frame semantics, namely, the idea that frames are not only a tool of semantic analysis but also the universal format of conceptual representation structuring our know ledge of and our interactions with the world that surrounds us. Semantic frames, thus, potentially allow for a description of all knowledge structures underlying discourse at different levels of abstraction. By integrating the concept of argumentative relations in the established methodology of frame analysis, these different dimensions of discursive meaning construction become describable in frame semantic terms. These argumentative relations between discourse elements at the text surface can be seen as mirroring equivalent relations between the constituent elements of cognitive frames at the conceptual level. This approach will be used in the empirical section to analyse the parliamentary discourse on nuclear energy in the French Assemblée nationale and the German Bundestag from 1946 to 2012.

台灣核能保險保費估計模式之建立

薛人銓 Unknown Date (has links)
本論文之目的在於瞭解現行核能保險之保單內容,歸納出核能事件發生後的各項損失,以建立一套台灣核能保險保費之估計模式。 該模式的建立包含以下步驟:首先,針對核能事件所造成的各項人身、財產、責任損失進行分類;其次,建立個別損失金額之評估公式。第三,對於核能電廠發生損失的機率與幅度分別進行探討。在損失機率方面,配合台灣核能電廠過去的損失經驗以及核研所之PRA(probabilistic risk assessment)模型,對於各級核能事件之發生機率進行假設。在損失幅度方面,估計各項損失項目之最大損失金額,配合各級核能事件下各項損失項目之損害比例,對於各級核能事件之損失幅度進行假設。最後,各級核能事件損失機率與損失幅度乘積之總和,即代表核能保險之危險保費;此外,加上附加費用後,即可求得適當的保費金額。 核能保險雖然是迅速且容易取得之財務補償工具,但所費不貲。整體而言,核能發電具有成本低、污染少等優點,若核能電廠能確保其安全性,並於損失發生後有足夠的財務保證,則可使核能發電的效益充分發揮。 / The aim of this article attempts to know the content of the nuclear energy insurance policy, to induce all kinds of losses after the nuclear events, and to establish an assessment model for the premium of the nuclear energy insurance in Taiwan. This model consists of the following steps: First, various kinds of personal, property, and liability losses which occurred after nuclear events are classified into different categories. Secondly, assessment formula for the loss amount is established. Third, loss frequency and loss severity for the damage of nuclear power plants are studied separately. Lastly, the result of multiplying “loss frequency” by “loss severity” stands for the risk premium for the nuclear energy insurance. Also, adding together the above results and the loading expense, the appropriate premium amount can be figured out. On the whole, utilizing nuclear energy for producing electric power possesses the advantage of being low costs and less pollution. If the nuclear power plants can ensure its safety as fully as possible, and provide adequate financial guarantees as damages occur, people will greatly benefit from the efficiency of nuclear power.

Före och efter Fukushimaolyckan : Svenska dagstidningars rapportering om kärnkraft

Larsson, Josefina January 2011 (has links)
Den 11 mars 2011 inträffade en kärnenergiolycka i Fukushima, Japan. Jag har gjort en diskursanalytisk innehållsanalys av fyra svenska dagstidningars artiklar om kärnenergi från de 90 dagarna innan kärnenergiolyckan i Japan, de första 90 dagarna efter den samt de därefter följande 90 dagarna. Jag har även jämfört de tendenser som framkommer i rapporteringen med Sveriges befolknings attityder till kärnenergi för att se om det finns något samband mellan dessa. Syftet var att utifrån mina resultat, tidigare forskning och teorin från forskningsfältet ”communication of science” analysera den eventuella påverkan medias rapportering om kärnenergi och allmänhetens syn på kärnenergi kan ha på varandra. Analysen visar att det finns ett samband mellan tidningarnas rapportering och allmänhetens åsikter och att det är troligt att parterna påverkar varandra. Vidare studier skulle dock krävas för att säkert kunna uttala sig om hur parterna påverkar varandra.

From atomic energy to nuclear science: a history of the Australian Atomic Energy Commission / History of the Australian Atomic Energy Commission

Binnie, Anna-Eugenia January 2003 (has links)
Thesis (PhD)--Macquarie University, Division of Information & Communication Sciences, Department of Physics, 2003. / Bibliography: p. 269-277. / Introduction -- Oliphant: a finger in many pies -- Men of vision and a world power in embryo -- The birth of the Commission -- We need secrets to trade: the Beryllia Project -- The Commission: a hive of activity -- The reactor that never was: the Jervis Bay Project -- The reinvention of the Commission -- The Commission is dead, long live ANSTO -- Conclusion. / Nuclear energy was once seen as a possible answer to man's energy needs, but it could also be used to produce the most destructive weapons known. The initial research into the phenomenon of nuclear fission was done at university laboratories in Europe on the eve of the Second World War. This war led to the development of the first nuclear weapons. After the war, many nations wanted access to both the weapons and the source of cheap power that the process of nuclear fission provided. Australia was one such nation. -- The Australian Government wanted nuclear energy to help develop the dry interior of the continent. There were many in Government who also wanted nuclear weapons. This work focuses on the Australian pursuit of nuclear energy for peaceful uses. The achieve this aim an organisation was established which would train scientists and engineers in nuclear science and technology. This organisation, the Australian Atomic Energy Commission, is the subject of this thesis. -- This work will examine the political influences that governed the Commission in its function and scientific research paths. Specifically, it will examine how successive governments caused the Commission to cancel projects, change the direction of its research, attempted (on several occasions) to amalgamate the Commission with the CSIRO, forcing the organisation into uranium mining and finally abolishing it and replacing it with a new organisation, the Australian Nuclear Science and Technology Organisation. Government interference would continue with this new organisation which had its entire board dismissed in 1993. -- The Commission was essentially a scientific and engineering organisation and hence this thesis will also consider a number of projects with which the Commission was involved such as the Beryllium Project, uranium exploration and mining, the uranium enrichment programs, the purchase of two nuclear reactors, the Synroc project, and the ill-fated Jervis Bay power reactor project. Other projects which were started in the early days of the Commission, the neutron diffraction work and the isotope production projects, will be mentioned in passing. Both these projects require a more detailed appraisal than is possible in this thesis. / Mode of access: World Wide Web. / viii, 278 p. ill

Nos bastidores da criação da Comissão Nacional de Energia Nuclear: disputas políticas e interesses econômicos / In the backstage of the creation of the Comissão Nacional de Energia Nuclear: political disputes and economic interests

Tatiane Lopes dos Santos 28 September 2009 (has links)
O objetivo desta dissertação de mestrado é analisar o processo de criação e regulamentação da Comissão Nacional de Energia Nuclear (CNEN), desde o governo Juscelino Kubitschek (1956-1961) até sua efetiva regulamentação em 1962. A iniciativa inscreveu-se no conjunto de medidas visando dar solução à crise que atravessava o Conselho Nacional de Pesquisas (CNPq), e que levariam à instauração, na Câmara dos Deputados, em 1956, de Comissão Parlamentar de Inquérito para investigar o problema da energia atômica no país. Como sinônimo de desenvolvimento e progresso, a energia nuclear também seria incluída no Programa de Metas de JK. São investigadas as disputas políticas e os interesses econômicos que marcaram o processo de implantação da CNEN e o desenvolvimento de suas atividades na etapa inicial de seu funcionamento. / This Masters dissertation aims at analyzing the creation and rules determining process of the Comissão Nacional de Energia Nuclear (CNEN), from Juscelino Kubitscheks government (1956-1961) to its effective establishment on 1962. The initiative was part of a set of measures with the purpose of resolving the crisis that affected the Conselho Nacional de Pesquisas (CNPq), which would lead to the establishment of a Comissão Parlamentar de Inquérito, in the House of Representatives in 1956, in order to investigate the atomic energy problem in the country. As a synonym of development and progress, nuclear energy also would be included in the Programa de Metas of JK. It will also investigate the political disputes and economic interests, which characterize the implementation of CNEN and its activities in the early years.

Discutir assuntos sociocientíficos de importância atual e apresentar o conhecimento científico como um conjunto dinâmico, provisório e socialmente construído de possíveis explicações são encaminhamentos necessários ao Ensino de Ciências dos anos presentes e futuros, aproximando-o de uma abordagem mais externalista das Ciências. A argumentação, como forma de socialização dialógica do conhecimento científico, já foi apontada por diversos autores como um poderoso recurso metodológico para aulas de Ciências. No entanto, o desenvolvimento de competências argumentativas ainda passa longe dos atuais cursos de Licenciatura. O estudo aqui descrito foi realizado com sete estudantes do último ano de um curso de Licenciatura em Física que cursavam a disciplina de Didática das Ciências (DdC) de uma universidade pública do estado de São Paulo e teve como objetivo principal compreender de que forma dinâmicas argumentativas sobre assuntos sociocientíficos podem contribuir para a construção de saberes docentes de argumentação entre os licenciandos. O debate, organizado na forma de uma audiência pública simulada, teve como tema principal as possibilidades para o plano nuclear brasileiro nos próximos anos. Os estudantes foram agrupados em duplas que deveriam representar quatro setores de interesse no assunto, sendo que cada estudante escolheu um nome e um cargo fictício. Essa dinâmica de role-play educacional parece ter facilitado as interações discursivas e incentivado os estudantes a pesquisarem antes de vir para o debate. A atividade foi gravada em vídeo para posterior transcrição e análise dos episódios segundo referenciais específicos da Sociolinguística e da Argumentação no Ensino de Ciências. / The initial teacher education is a key moment in the constitution of licentiate1 students, as they become future teachers, since it is probably in this stage when the first reflections on the various educational, pedagogical, political, and social dimensions involved in the processes of teaching and learning are undertaken. Discussing sociocientific issues of current importance and presenting scientific knowledge as a dynamic, temporary and socially constructed set of possible explanations are necessary developments for Science Education in the upcoming years, approximating it to a more externalist view of science. Several authors have already pointed out argumentation as a powerful methodological resource for science classes. However, the development of argumentative skills is still quite distant from the current licentiate majors. The study here described was performed with seven students in the final year of a Physics licentiate major, who were attending the course of Science Didactics in a public University in the State of São Paulo. The research had as its main goal to understand how an argumentative dynamic about socioscientifc issues can contribute to the construction of argumentative teacher knowledge among the students. The debate, organized in the form of a simulated public hearing, had as its main theme the possibilities for the Brazilian nuclear plan in the next few years. Students were grouped in pairs that should represent four sectors of interest in the nuclear matter and each student chose a name and title. This dynamic of educational role-play seems to have facilitated the discursive interactions and incentivated students to search for information before coming to the debate. The activity was recorded on video for later transcription and the analysis of the episodes was done according to references on sociolinguistics and argumentation in science education.
