Arguments regarding the relationship between media discourse and public opinion have raged for decades, if not centuries. COmparing media coverage of biotechnology between 1992 and 2001 in two national newspapers with national survey data collected in early 2003, an argument is made that a general one-dimensional media effect is not occurring within the US public regarding media discourse. Given the multivalent characteristics of the media and the interpretive filters used by audiences - including ignoring information - even strong slants by the presumed opinion-leading press (the New York Times and the Washington Post) do not predict public opinion on a nascent issue such as biotechnology. While some observations show these mirrors to be ephemeral. 相似文献

Whenever a new, potentially controversial technology enters public awareness, stakeholders suggest that education and public engagement are needed to ensure public support. Both theoretical and empirical analyses suggest, however, that more information and more deliberation per se will not make people more supportive. Rather, taking into account the functions of public sense-making processes, attitude polarisation is to be expected. In a real-world experiment, this study on synthetic biology investigated the effect of information uptake and deliberation on opinion certainty and opinion valence in natural groups. The results suggest (a) that biotechnology represents an important anchor for sense-making processes of synthetic biology, (b) that real-world information uptake and deliberation make people feel more certain about their opinions, and (c) that group attitudes are likely to polarise over the course of deliberation if the issue is important to the groups. 相似文献

Recent policies to promote biotechnology are motors of broader R&D reform in Germany and Japan. The idiosyncrasies of biotechnology commercialization could not be readily accommodated by these countries’ traditional technology policies, thus prompting reforms in institutions governing the commercialization of basic scientific research. These reforms provide a novel perspective on the nature of innovation in biotechnology; while previous research has underlined factors such as the national science base, industry–university links, entrepreneurship and venture capital, the German and Japanese cases highlight the importance of other mediating variables such as the level of public governance within national research institutions, the autonomy of the university/research sector, and the historical role of the public sector generally. 相似文献

This essay analyzes how academic institutions, government agencies, and the nascent biotech industry contested the legal ownership of recombinant DNA technology in the name of the public interest. It reconstructs the way a small but influential group of government officials and university research administrators introduced a new framework for the commercialization of academic research in the context of a national debate over scientific research's contributions to American economic prosperity and public health. They claimed that private ownership of inventions arising from public support would provide a powerful means to liberate biomedical discoveries for public benefit. This articulation of the causal link between private ownership and the public interest, it is argued, justified a new set of expectations about the use of research results arising from government or public support, in which commercialization became a new public obligation for academic researchers. By highlighting the broader economic and legal shifts that prompted the reconfiguration of the ownership of public knowledge in late twentieth-century American capitalism, the essay examines the threads of policy-informed legal ideas that came together to affirm private ownership of biomedical knowledge as germane to the public interest in the coming of age of biotechnology and genetic medicine. 相似文献

A long stream of academic literature has established that public funding towards research and development matters for economic growth because it relates to increases in innovation, productivity and the like. The impact of public funding on the creation of new firms has received less attention in this literature despite theoretical constructs that support such association. In the present paper we study whether indeed there is a relationship between public research funds and local firm births in the context of the U.S. biotechnology industry. In doing so, we introduce a number of changes that strengthen the robustness of our findings when compared with existing literature. These changes include a direct measure of research expenditures and a considerably lengthier longitudinal dataset which allows us to capture a structural relationship and not a chance event. We empirically demonstrate that increases in the level of research funding from the National Institutes of Health towards biotechnology associate with increases in the number of biotechnology firm births at the Metropolitan Statistical Area level. Further, we reveal that public funds towards established firms associate with local firm births considerably more strongly when compared with funds towards universities and research institutes/hospitals. We conclude the paper with academic and policy implications of the present work that highlight the complexity of factors that underlie the creation of local firms in high technology industries. 相似文献

This paper addresses the use of metaphors in creating public representations of biotechnology in the United Kingdom's leading quality press. Metaphors referring to biotechnology and its applications have been analyzed in press articles covering the period 1973-1996. The paper describes how metaphors can be used to popularize complex technical information while at the same time providing a highly charged message about the technology itself. The analysis draws conclusions about the content and general direction of the debate on biotechnology during the past three decades. 相似文献

Despite considerable research in advanced countries on public perceptions of and attitudes to modern biotechnology, limited effort has been geared towards developing a structural model of public attitudes to modern biotechnology. The purpose of this paper is to identify the relevant factors influencing public attitudes towards genetically modified (GM) soybean, and to analyze the relationship between all the attitudinal factors. A survey was carried out on 1,017 respondents from various stakeholder groups in the Klang Valley region. Results of the survey have confirmed that attitudes towards complex issues such as biotechnology should be seen as a multifaceted process. The most important factors predicting support for GM soybean are the specific application-linked perceptions about the benefits, acceptance of risk and moral concern while risk and familiarity are significant predictors of benefit and risk acceptance. Attitudes towards GM soybean are also predicted by several general classes of attitude. 相似文献

随着Web2.0的迅猛发展和广泛运用,虚拟社会越来越呈现出小世界网络的特性,英国伦敦骚乱以及刚刚爆发的俄罗斯游行事件,煽动者均借助社交网站进行舆论散播.网络舆论愈发成为影响国家利益、事关国家安全的重要因素,若不对网络舆论给予及时关注和正确引导将对经济和社会造成不可估量的影响和损失.因此,如何进行网络舆论引导是新时期对完善和创新社会管理中创新管理理念、方法和手段提出的新挑战.本文的网络舆论引导研究试图回答两个问题:(1)是否需要引导？(2)如何加以引导？为此,首先提出网络舆论事件是否需要引导的3种研判方法,若加以引导,则进一步利用社会网络分析方法对舆论领袖及潜在关键人物进行探测和挖掘,给出引导策略,为创新社会管理中的网络舆论引导提供科学和定量的研究基础. 相似文献

While technology transfer at universities has received considerable attention in the innovation and entrepreneurship literature, we know much less about technology transfer at national/federal labs and (non-university) public research institutes. In this article and the related special section, we aim to fill this void. We provide a rationale for our special section on technology transfer from national/federal labs and public research institutes, summarize the papers in the special section, highlight research questions, theories, data and methods, key findings and conclusions. We conclude by outlining a research agenda for multi-level research on agents, institutions, and regions to improve our understanding of the managerial and public policy implications of technology transfer from these institutions. 相似文献
