Of Frogs & Rhetoric: The Atrazine Wars     

Carol Reeves 《Technical Communication Quarterly》2015,24(4):328-348

In a scientific dispute over the effects of atrazine on amphibians, chemical industry–funded and publically funded scientists present stunningly contrasting constructions of atrazine's environmental concentrations, persistence, and potential to harm. Considerable scientific uncertainties and variable ranges allow authors to construct preferred versions of the story of atrazine. These incommensurate rhetorical constructions, more the result of competing economic and environmental interests than of any paradigmatic misalignments, have prolonged the dispute not only over atrazine's effects but also over whether its sales should be banned.  相似文献   

Prejudices Unshelved: Variation in Attitudes toward Controversial Public Library Materials in the General Social Survey, 1972–2014     

Jeremy Brett  Mary E. Campbell 《Public Library Quarterly》2016,35(1):23-36

Using the General Social Survey from 1972–2014, we examine variation in attitudes toward retaining controversial materials in libraries. Previously controversial topics have become much more widely accepted. We find that other controversies remain, showing how global conflicts become intertwined in local cultural controversies, and how the perceived threat from particular groups informs public concern with disseminating information from those groups. We find that more frequent library users are somewhat less likely to want to remove controversial books from the shelves, although some of these relationships are explained by variation in the respondent’s age, race, and other characteristics.  相似文献

夏洛克作为欧洲文学的艺术典型，莎士比亚的成功之处在于以动态的视野从整体上去把握人物。夏洛克是被作为一个不断变化角色的圆形人物来塑造的，他的高度个性化来自其性格因素的对立统一运动。  相似文献   

五四时期知识界的民主政制设计及论争     

肖高华 《连云港师范高等专科学校学报》2011,(3):82-86

对立宪民主的追求是近代中国政治的主旋律。然而五四时期,受激进主义与保守主义思潮的影响,在中国知识界中形成了不同的民主观,设计出了异样的民主政制。激进知识分子对民主的理解发生了根本转变,主张直接民权、平民政治、阶级政治等,而胡适学人群、研究系学人群等坚守民主的原本意义,主张代议政治、贤能政治、阶级调和等。重温五四时期知识界关于民主政制的设计及论争,对当前我国民主政治的发展具有一定的启示作用。  相似文献   

美国教师教育的解制与专业化之争     

鞠玉翠  陈汉珍 《外国教育研究》2011,(11):73-77

在美国教师教育领域,解制和专业化是两大论争阵营。解制取向否定教师教育的必要性,批评教师教育在学科知识方面低标准和在教育类课程方面"高栅栏",倡导用替代性途径绕过正规教师教育,期望以较高效率达到提高学生成绩的目的;专业化取向把"解制"的观点看作是"外行"的,批驳其简单化理解,同时又将其看作挑战,主张认识教师教育的复杂性和不可替代性,通过高投入达到真正的高标准,让教师教育真正成为受人尊敬的专业。  相似文献

科学可以计划吗？——二十世纪三四十年代以英国为中心的争论          下载免费PDF全文

马峥  王娜  周国臻  潘云涛 《科学学研究》2012,30(7):961-975

 发生于1930年代末的关于科学是要计划还是要自由的贝-波之争,其源流可追溯到第二届国际科学史大会。整个三十年代英国科学家中的科学与社会运动,是该争论的过程因素。该争论实非二人之争,而是存在于两个科学家群体之间,Nature杂志在其中起到了推波助澜的作用,若干科学组织牵涉其中,争论所涉及范围远超英国之外,过程比较曲折,历史影响极为深远。科学家们争论的问题包括科学、计划和自由的内涵,科学发展的机制,科学家的责任,科学的社会关系等等问题。它不仅促生了科学学、科学社会学等学科,而且将科学哲学和科学史研究推向一个新的高潮。更为重要的是,这场争论极大地改变了人们的科学观念,它使功利主义科学观从此深入人心,与之后苏联之外各国科学的计划化不无关系。  相似文献   

Revisiting the Spheres of Public Discussion     

Lotta Lounasmeri 《Journalism Practice》2017,11(10):1302-1318

When societal elites seem to be in consensus about a political issue, journalism traditionally takes on a more conservative role in organising public discussion. For an issue to become controversial in mainstream media, a crisis of some kind is often needed, followed by lack of consensus among the different elites. This article uses coverage of globalisation in Finland’s most influential newspaper to see if the theory of the spheres of public discussion can be applied to a particular journalistic culture. The model is used to see how media treat elite and non-elite actors who wish to participate in public discussion. In order to draw conclusions about how the media operate regarding giving voice to dissent or upholding the status quo in society, it is necessary to take into account the historical and social context of the relationship between a country’s media and the state.  相似文献   

Bond graph models of structured parameter uncertainties     

Casimir Sié Kam 《Journal of The Franklin Institute》2005,342(4):379-399

Taking into account uncertainties in model parameter values is a crucial point for studying robustness in modeling and in control. This paper proposes to construct in a systematic and graphical procedure two forms of the linear state equation usually found in the literature for dealing with the robustness problem in the case of structured uncertainties on parameters. It is shown how to model uncertainties in a bond graph approach, in the case of additive or multiplicative parametric variations.  相似文献
