近现代科学采用祛语态化等修辞手段,反映并展现了理想主义科学观,可称之为理想主义科学修辞。这不能反映科学活动的真实状况,需要结合科学史、科学哲学、科学社会学等的研究成果,重新采用语态化解释等修辞手段,返语境化,尽量还科学真实面貌。不仅如此,复杂性科学、基础应用研究和战略性基础研究的兴起,需要科学修辞的语境化转向：一是更多地走向文学性的语境诉求;二是在科学文本之外,面向社会交往实践,进行外在主义语境修辞。 相似文献

当今“人本论”的教育观已将教学中心由知识转向人,转向学生的情感和心灵。科学的课堂模式是适应当前这一教育教学改革要求的基础。构建课堂语境能提高教师语言的功效,本文旨在探讨课堂语境构建的可行性以及构建手段及其意义。 相似文献

科学传播是科学知识、科学方法、科学精神和科学意识在科学共同体内部及与社会之间的扩散与再建构过程。科学传播伦理探讨的哲学基础有科学实在论转向科学建构论,科学功用与科学精神的背离,公众理解科学由缺失模型转向民主模型。科学共同体在科学传播中负有"保证科学成果信息的真实性与透明性;客观公正地传播科学成果的价值和社会影响;尊重公众实际理解能力,适度简化对科学知识的表述"等伦理责任。 相似文献

语境论作为一种世界观与方法论,在逐步被人们所理解的同时,也渗透到科学史的研究中,对传统科学史观进行了诸多反思。文章不仅从历史语境时功利主义、实证主义和批判主义三种传统科学史观提出反思,而且从社会语境的角度对传统科学史观进行了理性消解。文章主张语境的、价值中立而多元的科学史观,为语境论科学史观的建立作理论上的辩护。 相似文献

科恩的科学观是一种语境论科学观。科学本体来源子历史语境,科学发展是历史和科学语境中科学观、传统与进步的更替,科学价值体现历史、科学和社会语境中科学对相关科学、社会和民众的多元功能性。科恩的语境论科学观体现了逻辑与历史的统一性、科学史与科学哲学的融合性、语境广义性、证据性和方法的多元性。 相似文献

民生科技发展的广义语境包括民生科技主语境和支撑语境。广义语境模型反映民生科技发展具有普遍联系性、客观现实性、主体多元性、学科融合性、社会实践性、动态协同性、边界开放性和可评估性等特征。为了加快民生科技发展,我们需要不断完善民生科技传播渠道,丰富民生科技学科体系,加快民生科技产业化发展,建立政府、企业、大学、科研院所等协同创新网络,提高民生科技要素体系支撑力度,扩展民生科技国际合作途径,加强民生科技评估力度。 相似文献

科学的语境性表明,语境规制着科学的意义与实在,界定着科学与非科学,吸引了社会对主流学科和理论的支持,使科学研究力量得以凝聚.中国近年科研论文数量的增长并没有提升其科研实力,表明中国科学研究的原创性仍然很低.造成科研原创性低的原因在于对现有科学理论的盲目崇拜,其结果是只能在“常规科学”下拾遗补缺,暴露出了科学主义语境下原始创新的困境. 相似文献

科学传播的理论与实践在经过“科学普及”、“公众理解科学”、“科学对话”等阶段时候开始逐渐进入“公众参与科学”领域。然而传统的“公众参与科学”所强调的实践多集中在科学民主化与科学决策上。“公众科学”概念的出现开始将“公众参与科学”引入到一个全新的科学知识生产领域。本文梳理了“公众科学”概念在西方语境中的提出与发展,并将其与科学传播体系中的其他相关概念进行了比较分析,并结合实际案例阐述了“公众科学”项目的实践模式。最后,在比较“公众科学”在实践中的利弊的基础上为其未来发展提出了讨论。对“公众科学”领域的研究不仅有助于我们与西方科学传播领域的研究相接轨,更有助我们利用全新的理论体系与实践方法为提高公民科学素养提供助力。 相似文献

Utilizing the Technology-Organization-Environment (TOE) theory and the literature on citizen engagement, we formulated a multiple-mediation model examining (1) the TOE contextual factors affecting government’s willingness to implement electronic participation (e-participation) in form of e-information sharing, e-consultation, and e-decision-making in a country and its electronic government (e-government) maturity; and (2) the mediating role of government’s willingness to implement e-participation in a country on the relationships between its TOE contextual factors and e-government maturity. Specifically, we hypothesized that information and communication technology (ICT) infrastructure (representing the Technology context), governance (representing the Organization context), and human capital (representing the Environment context) has both direct and indirect relationships with e-government maturity through the mediating roles of government’s willingness to implement e-participation. Based on archival data from 183 countries, results showed that while ICT infrastructure and human capital were positively associated with government’s willingness to implement e-participation and e-government maturity, governance was not significantly associated with them. Also, government’s willingness to implement e-participation had significant associations with its e-government maturity. Specifically, of three dimensions of e-participation, government’s willingness to implement e-information sharing and e-decision-making were positively associated with e-government maturity, and its willingness to implement e-consultation was negatively associated. Further, government’s willingness to implement e-information sharing, e-consultation, and e-decision-making partially mediated the influences of ICT infrastructure and human capital on e-government maturity. Results also indicated that the relationship of governance with e-government maturity was not mediated by government’s willingness to implement e-participation. Findings contribute to the theoretical discourse on e-government by highlighting the roles of the TOE contextual factors on government’s willingness to implement e-participation and e-government maturity, and provide indications for practice in managing e-government maturity by (1) enhancing government’s willingness to implement appropriate e-participation dimensions; and (2) leveraging the effects of the TOE contextual factors on government’s willingness to implement e-participation and e-government maturity. 相似文献

Learning from education to communicate science as a good story 总被引：1，自引：0，他引：1
Science communicators must learn from science educators in their crusade to counteract the traditional boring and inefficient approaches to convey science. Educators encounter a need for methods of teaching that portray science as 'hard fun' and resources that encourage students' minds to burst into action. Narratives are considered by several authors as highly valuable resources for science education. However, little research has been undertaken to measure the efficiency of narratives in the context of science communication to the general public. Recent work however, suggests that narratives are indeed an alternative and an important means for science communication to convey information in an accurate, attractive, imaginative and memorable way. To present scientific information through stories, novels, comics and plays should be regarded as an important means to transmit information in the repertoire of both science teachers and science communicators. 相似文献

Adapting information retrieval to query contexts 总被引：1，自引：0，他引：1
In current IR approaches documents are retrieved only according to the terms specified in the query. The same answers are returned for the same query whatever the user and the search goal are. In reality, many other contextual factors strongly influence document’s relevance and they should be taken into account in IR operations. This paper proposes a method, based on language modeling, to integrate several contextual factors so that document ranking will be adapted to the specific query contexts. We will consider three contextual factors in this paper: the topic domain of the query, the characteristics of the document collection, as well as context words within the query. Each contextual factor is used to generate a new query language model to specify some aspect of the information need. All these query models are then combined together to produce a more complete model for the underlying information need. Our experiments on TREC collections show that each contextual factor can positively influence the IR effectiveness and the combined model results in the highest effectiveness. This study shows that it is both beneficial and feasible to integrate more contextual factors in the current IR practice. 相似文献
