A NÃO NEUTRALIDADE NA PERSPECTIVA EDUCACIONAL CIÊNCIA-TECNOLOGIA-SOCIEDADE / THE NON NEUTRALITY IN THE EDUCACIONAL PERSPECTIVE SCIENCE-TECHNOLOGY-SOCIETY

Santos, Rosemar Ayres dos 27 January 2012 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The origin of the movement known as Science-Technology-Society (STS), with repercussions in the Science Education, is associated to the questioning of the supposed neutrality of Science & Technology (CT). In Science Education, in the Brazilian context, STS can be considered a growing line of research, in a process of consolidation. However, how the nonneutrality of Science & Technology has been worked, in this line of research, considering the production of knowledge present in Brazilian journals from the area of Science Education? This constitutes the research problem. It is aimed to analyze how the non-neutrality of CT, in the CTS line of research, has been worked on the production of knowledge, present in Brazilian journals in the area of Science Education. As specific objectives: to identify and to characterize the approach given to the dimensions of the non-neutrality of Science- Technology in Brazilian journals, from the area of Science Education; to deep the understanding about the non-neutrality of Science-Technology and to signal referrals for the Science Education, which contribute to the understanding of non- neutrality of Science- Technology, particularly in the field CTS. In terms of theoretical and methodological referrals, consists of qualitative research, bibliographical, being the corpus of analysis constituted from articles presented in three journals published in Brazil, of the area of Science Education. This was submitted to the discursive textual analysis, which consisted of three steps: unitarization, categorization and communication. From the search results, was produced a metatext. The interaction between theoretical and empirical elements resulted in three categories, which summarize the research results: a) the agenda transfers intentions to the scientific-technological product; b) partial understanding of the non-neutrality of CT; and c) the knowledge produced (product) does not is the result only of the traditional epistemic factors: logic + experience. / A origem do denominado movimento Ciência-Tecnologia-Sociedade (CTS), com repercussões na Educação em Ciências, está associada ao questionamento da suposta neutralidade da Ciência-Tecnologia (CT). Na Educação em Ciências, no contexto brasileiro, CTS pode ser considerada uma linha de pesquisa em crescimento, num processo de consolidação. Contudo, como a não neutralidade da Ciência-Tecnologia tem sido trabalhada, nesta linha de pesquisa, considerando a produção de conhecimento presente, em periódicos brasileiros, da área de Educação em Ciências? Este constitui-se no problema de pesquisa. Tem-se como objetivo geral analisar como a não neutralidade da CT, na linha de pesquisa CTS, tem sido trabalhada, na produção do conhecimento, presente em periódicos brasileiros, na área de Educação em Ciências e objetivos específicos: identificar e caracterizar a abordagem dada, à dimensão da não neutralidade da Ciência-Tecnologia, em periódicos brasileiros, da área de Educação em Ciências; aprofundar a compreensão sobre a não neutralidade da Ciência-Tecnologia e sinalizar encaminhamentos, para a Educação em Ciências, que contribuam para a compreensão da não neutralidade da Ciência-Tecnologia, particularmente no campo CTS. Em termos de encaminhamento teórico-metodológico, constitui-se de pesquisa qualitativa de cunho bibliográfico, sendo o corpus de análise constituído a partir de artigos presentes em três periódicos, editados no Brasil, da área de Educação em Ciências. Este foi submetido à análise textual discursiva, constituída de três etapas: unitarização, categorização e a comunicação, sendo que, dos resultados da pesquisa, resultou a produção de um metatexto. Da interação entre elementos teóricos e empíricos resultaram três categorias, as quais sintetizam os resultados da pesquisa: a) a agenda transfere intencionalidades para o produto científico-tecnológico; b) compreensão parcial da não neutralidade da CT e c) o conhecimento produzido (produto) não é resultado apenas dos tradicionais fatores epistêmicos: lógica + experiência.

NÃO NEUTRALIDADE DA CIÊNCIA-TECNOLOGIA: PROBLEMATIZANDO SILENCIAMENTOS EM PRÁTICAS EDUCATIVAS RELACIONADAS À CTS / NON-NEUTRALITY OF SCIENCE TECHNOLOGY: QUESTIONING SILECING IN EDUCATIONAL PRACTICES RELATED TO STS (SCIENCE-TECHNOLOGY-SOCIETY)

Rosa, Suiane Ewerling da 16 April 2014 (has links)
The STS movement has as a main objective the democratization of decision-making on social issues involving science-technology (ST). Also, this arises in contexts in which the supposed neutrality of ST began to be questioned. Neutrality understood as legitimizing technocratic decision models. In the educational field, I seek curriculum geared toward to the creation of a culture of participation, based on reference Freire-STS and LATSTS (Latin American Thought in Science Technology Society). As well, my research problem was: Historic Buildings, called myths, in other words, the supposed neutrality / superiority of technocratic decision model, the Salvationist perspective / redeeming attributed to ST and scientific-technological determinism, sustained and feeding back the supposed neutrality have been worked on educational practices related to the Science-Technology-Society? Which referrals have been given? The objectives that guided the research were: i) identify, in educational practices presented in the literature of the area, the approaches given to the three historic buildings; ii) analyze and deepen the featured aspects in regard to the three historic buildings, in a vision of non-neutrality of ST; and iii) signal parameters to Science Education in order to support proposals for educational practices. Methodologically, consisted of a qualitative research, bibliographic nature, being the corpus of analysis consisting of six articles published in journals in the field of Science Education. I used the Textual Discourse Analysis, which resulted in three categories of analysis: a) Silencing on the design of ST may be signaling an endorsement to a close understanding of the scientific-technological determinism; b) Silencing on dimensions other natures, beyond the scientific-technological in decision-making processes; and, c) Silencing about the values internalized in the scientific-technological product. / O movimento Ciência-Tecnologia-Sociedade (CTS) tem como um dos objetivos centrais à democratização de processos decisórios sobre temas sociais envolvendo ciência-tecnologia (CT). Também, este surge em contextos nos quais a suposta neutralidade da CT passou a ser questionada. Neutralidade entendida como legitimadora de modelos decisórios tecnocráticos. A pesquisa está inserida na busca de currículos voltados para a constituição de uma cultura de participação, apoiada nos referenciais Freire-CTS e no Pensamento Latino Americano em Ciência-Tecnologia-Sociedade (PLACTS). Assim, o problema de pesquisa foi: Construções históricas, denominadas de mitos, ou seja, a suposta neutralidade/superioridade do modelo de decisões tecnocráticas, a perspectiva salvacionista/redentora atribuída à CT e o determinismo científico-tecnológico, sustentadas e realimentando a suposta neutralidade, têm sido trabalhadas em práticas educativas relacionadas à CTS? Quais encaminhamentos têm sido dados? Os objetivos que guiaram a investigação foram: i) identificar, em práticas educativas, apresentadas em literaturas da área, as abordagens dadas a estas três construções históricas; ii) analisar e aprofundar os aspectos caracterizados no que tange as três construções históricas, em uma visão de não neutralidade da CT; e, iii) sinalizar parâmetros para a Educação em Ciências, fundamentando propostas de práticas educativas. Metodologicamente, constituiu-se de uma pesquisa qualitativa, de cunho bibliográfico, sendo o corpus de análise constituído de artigos publicados em seis periódicos da área da Educação em Ciências. Utilizou-se a Análise Textual Discursiva, da qual resultaram três categorias de análise: a) Silenciamento sobre a origem, sobre a concepção de CT pode estar sinalizando o endosso a uma compreensão próxima do determinismo científico-tecnológico; b) Silenciamento sobre dimensões de outras naturezas, além da científico-tecnológica, em processos decisórios; e, c) Silenciamento quanto aos valores internalizados no produto científico-tecnológico. Estas categorias, sintetizando os resultados da pesquisa, sinalizam desafios para a educação em ciências, particularmente para a constituição de uma cultura de participação.

Javascript and Politics: How a Toy Language Took Over the World

McQueen, Sean 01 January 2013 (has links)
The most important programming languages are the ones that manage to capitalize on emerging frontiers in computing. Although JavaScript started its life as a toy language, the explosive growth of the web since 1995 and the invention of the web application have transformed the language’s syntax, potential and importance. JavaScript today is powerful and expressive. But is the language good enough to power the future of the web? How does the messy political past of JavaScript affect web development today, and how will it affect web development in the future? The paper first examines the political history of JavaScript from its origins at Netscape through today. Then a case study of pure JavaScript web development using the NodeJS and AngularJS is presented and analyzed. Finally, several potential paths forward for the language are considered, including a discussion and analysis of Microsoft’s TypeScript, Mozilla’s ASM.js and Google’s Dart.

Hur effektiv och säker är kombinationen av sofosbuvir och velpatasvir mot kronisk hepatit C-infektion

Rydén, Björn January 2017 (has links)
Around 130-150 million people are chronically infected with hepatitis C-virus today. Personal suffering and great societal costs aside, this also causes around 400 000 deaths every year due to complications. Earlier treatments with pegylated interferon and ribavirin were both ineffective and had a lot of side effects, but in recent years new treatments using direct-acting antivirals that are both more effective and has less side effects have been introduced. The downside with these are that their effectiveness depends on which HCV genotype the patient has, which requires costly and time consuming pre-treatment examinations before treatment can begin. This paper investigates clinical studies in which the effectiveness and side effects of a new combination of drugs containing sofosbuvir and velpatasvir is tested. The studies where found through PubMed, and they are what the usage of these drugs in health care is based on. The studies show that the combination of sofosbuvir and velpatasvir is effective, measured by sustained virological response, against all HCV genotypes irrespective of if the patient has a compensated or decompensated cirrhosis, or if the patient has had a previously failed treatment. The patients with decompensated cirrhosis also had an early improvement in liver function, but it is too early to say if the improvement is long lasting. The treatment also gave less side effects compared to pegylated interferon and ribavirin. The combination of sofosbuvir and velpatasvir was also shown to have a good effect amongst patients where resistance associated variants of NS5A and NS5B where found. The conclusion is that the combination of sofosbuvir and velpatasvir is an effective, but also at the moment expensive, treatment for HCV independent of genotype.

Prevalens av Trichomonas vaginalis i STI-prover från Västra Götalands län med Aptima™ TV Assay på Panther™ System : Samt utvärdering av Aptima™ TV Assay på Panther™ System med jämförelse mot Xpert® TV Kit på GeneXpert®

Johansson, Linnéa, Isaksson, Malin January 2017 (has links)
Abstract Prevalence of Trichomonas vaginalis in STI-samples from Västra Götaland county with Aptima™ TV Assay on Panther™ System Also, evaluation of Aptima™ TV Assay on Panther™ System with comparison with Xpert® TV Kit on GeneXpert® Trichomonas vaginalis is a parasite that is spread by sexual contact, it is also the biggest sexually transmitted infection in both the United States and Europe. The prevalence in Sweden today is unknown as no national basic data exist. The routine procedure of identification is Wet-Smear although nucleic acid amplification enable a higher level of specificity and sensitivity. Panther™ System and GeneXpert® are two systems using RNA respectively DNA for analysis. The objective of the study was primarily to investigate the prevalence of Trichomonas vaginalis in STI-samples from Västra Götaland county with Aptima™ TV Assay on Panther™ System and secondarily to evaluate Aptima™ TV Assay with comparison to Xpert® TV Kit on GeneXpert®. The evaluation and prevalence study took place at Clinical Microbiology, Unilabs AB, Skaraborgs Hospital Skövde during the period of April-May 2017. The results of the evaluation indicate that Aptima™ TV Assay is specific for Trichomonas vaginalis and that the sensitivity falls within the detection limits for the kit. Therefore, the kit is suitable for use in the prevalence study. The prevalence study displayed a positive outcome on two out of 606 analyzed patient samples, corresponding to 0.3%. The conclusion is that the prevalence is enough for further studies.
