Most Europeans are now and have been strongly in favor of theircountry's participation in the European Community. The conspicuousexceptions are the British and Danish publics who are scepticalof the benefit they will derive from their countries' involvementin the Community. The advent of 1992 and closer European integrationis focusing the minds of governments, political institutions,business organizations and pressure groups, if not really thepublics of the member states. It is certainly having an impacton strategic thinking in other areas of the world, includingespecially EFTA countries, the Eastern block countries, theUSA and Japan. Over the nearly two decades in which the Europeans'views of their country's membership of the Common Market hasbeen measured by the EC's Eurobarometer, the average level ofsupport has been 57 per cent with only about one EC citizenin ten opposed. The pace of European economic integration hasquickened with the agreement of the EC countries on economicharmonization by the target year, 1992. This has the supportof most Europeans and many also support further social, economicand political harmonization and even integration in the comingyears. The focus on 1992 has been only slightly deflected bythe recent events in the Eastern European countries, and mayhave the effect of strengthening and, over the long term, quickeningthese goals. 相似文献

This magazine has observed that “we have neither adequately gathered the history of broadcasting nor acknowledged its importance.” At that time the lack and loss of primary historical data that might be of future use to broadcasters was being decried. Painstaking analysis and synthesis of such data would be the next, and most directly valuable, step. The following article is that sort of historical writing. It should be of interest to every broadcaster, and of use to those here and in other countries who need to examine the antecedents of the American system of economic support for broadcasting. The thesis of this article argues that it is possible to locate a period in the late 1920's in which broadcast facilities, audiences, programs, and station owner attitudes, were “right” for the national advertiser to enter upon radio sponsorship in a serious way. 相似文献

Understanding the quality of science systems requires international comparative studies, which are difficult because of the lack of comparable data especially about inputs in research. In this study, we deploy an approach based on change instead of on levels of inputs and outputs: an approach that to a large extent eliminates the problem of measurement differences between countries. We firstly show that there are large differences in efficiency between national science systems, defined as the increase in output (highly cited papers) per percentage increase in input (funding). We then discuss our findings using popular explanations of performance differences: differences in funding systems (performance related or not), differences in the level of competition, differences in the level of university autonomy, and differences in the level of academic freedom. Interestingly, the available data do not support these common explanations. What the data suggest is that efficient systems are characterized by a well-developed ex post evaluation system combined with considerably high institutional funding and relatively low university autonomy (meaning a high autonomy of professionals). On the other hand, the less efficient systems have a strong ex ante control, either through a high level of so-called competitive project funding, or through strong power of the university management. Another conclusion is that more and better data are needed. 相似文献

Using ‘general trust in institutions’ and ‘conceptsof nature’ as examples, the article analyzes the influenceof cultural factors on sense-making of food biotechnology andthe resulting public attitudes in the USA and Germany. Accordingto the hypotheses investigated, different levels of trust andappreciation of nature explain part of the well-known differencesin attitudes between both countries. The analysis of a cross-culturalsurvey of the general population shows that appreciation ofnature is a predictor of attitudes in both countries. The higherappreciation of nature in Germany partly explains why attitudestowards food biotechnology are more negative in Germany thanin the USA. The relationship between trust and attitudes ismore complex than expected, however. Institutional trust isa moderate predictor of attitudes towards food biotechnologyin the USA but not in Germany. To explain the varying effectivenessof trust in resolving innovation-related uncertainty we referto differences in issue framing in both countries and to thehigher degree of universalism and individualism in the USA.We conclude that the higher relevance of trust and the lowerappreciation of nature make the U.S. culture more apt to assimilatetechnical innovations than the German culture. 相似文献

The explosion of information technology (IT) since the beginning of the 20th century rendered manual-based library systems, in academic, research, special and public libraries, irrelevant. Implementing information technology in the digital age depends largely on librarians' attitudes. This study examines the attitudinal correlates of selected Nigerian librarians towards the use and application of IT in their libraries. Forty-one librarians were surveyed from the four selected automated libraries in state of Oyo in Nigeria form the study's population. Two research questions were developed to guide the study. The results indicate that four out of the five variables age, gender, educational qualifications and prior knowledge of IT significantly correlate with the librarians' attitudes towards IT. The other variable, IT anxiety, correlates negatively with the librarians' attitudes towards IT. Findings further show that all the five variables significantly predict librarian's attitude towards IT with prior IT experience showing the greatest predictive effect. Based on these findings, libraries in the developing countries should consider sending their librarians, who do not have knowledge of IT, to IT training in order to remove fear and anxiety hindering them from developing a better attitude towards the use of IT in their libraries. 相似文献

Communication scholars have conflicting views on the relationship between exposure to science news and knowledge, and its subsequent influence on attitudes. Such mixed sentiments could arise from the vague definition of knowledge. Therefore, this paper explicates science knowledge into factual knowledge and subjective knowledge. It also compares the mediating roles of both types of knowledge between news attention and public support for science and technology (S&T). A survey of 967 Singaporeans showed that news attention was positively related to both factual and subjective knowledge. The findings revealed a stronger relationship between subjective knowledge and news attention than factual knowledge and news attention. Additionally, factual knowledge was positively related to public support for S&T, but subjective knowledge was negatively related to public support for S&T. The contrasting directions of these associations demonstrate that factual and subjective knowledge are two distinct dimensions of knowledge. Practically, the findings can inform policymakers and communication practitioners about effective public education and engagement initiatives. This study also provided guidelines for newsmakers in news reporting about S&T. 相似文献

This research proposes a holistic and integrative theoretical model to discuss the effects of eight predictors of citizens' attitudes towards open government and Government 2.0, and whether these attitudes influence their intention to use open government data in Brazil, one of the founding countries of the Open Government Partnership (OGP). Findings show the effects of six predictors of citizens' attitudes towards open government and government 2.0. In essence, these predictors are ease of use, usefulness, intrinsic motivation, political satisfaction, government trust, and intensity of internet use. This study also indicates that education, income, and region influence the ease of use and usefulness of open data. These findings also mean that public managers and political parties still have “homework’ to do to stimulate citizens' behavior towards open government and government 2.0. These initiatives encompass the government portals quality and data transparency improvement through less restrictive laws. Also, improve politicians' job performance. 相似文献

Although microbes directly impact everyone's health, most people have limited knowledge about them. In this article, we describe a museum and media public education campaign aimed at helping diverse audiences better understand emerging knowledge about microbes and infectious disease. Funded primarily by the Science Education Partnership (SEPA) program of the National Institutes of Health, this campaign involved crosscutting programs designed to extend impacts throughout a broad public audience. Collaborations with partners from public media, libraries, science education, the social sciences, and biomedical research centers extended our outreach to local and national audiences of adults and youth. Our campaign developed programs for radio broadcast, schools, libraries, museums, and publishers to ultimately reach over eight million people. In addition, we conducted a series of research studies focused on understanding the mental models that people create of the complex concepts of microbes and infectious disease and on how to engage hard‐to‐reach adolescents with this science content. These studies furthered our understanding of how people reason about unseen phenomena, the kinds of materials that might intrigue youth who claim little interest in science, and how to begin to combat misinformation pervasive in this field. Our comparisons of expert, teacher, and teen reasoning about microbes revealed their distinct mental models on the topics of infection, vaccination, and immune response. Our investigation of comics confirmed their power to motivate teenagers to want to read more about science. Across all levels of science identity, we found that youth were more engaged with the comics than with comparable essays. Together, these findings provide insights into how to educate a diverse public about emerging biomedical research. 相似文献

Early career researchers (ECRs) are of great interest because they are the new (and biggest) wave of researchers. They merit long and detailed investigation, and towards this end, this overarching paper provides a summary of the first‐year findings of a 3‐year, longitudinal study of 116 science and social science ECRs who have published nearly 1,200 papers and come from 7 countries and 81 universities. ECRs were interviewed in their own languages face‐to‐face, by Skype, or telephone. The study focused on the attitudes and behaviours of ECRs with respect to scholarly communications and the extent to which they are adopting new and disruptive technologies, such as social media, online communities, and Open Science. The main findings include: publishing in high‐impact factor journals is the only reputational game in town; online scholarly communities, and ResearchGate in particular, are gaining ground; social media are beginning to have an impact, especially in the dissemination arena; outreach activities have become more important; libraries are becoming increasingly invisible to ECRs; Open Science is not gaining traction; and more transformational ideas are being expressed, especially in the US and UK. 相似文献

This paper presents a comparative analysis of the structure of national higher education networks in six European countries using interlinking data. We show that national HE systems display a common core–periphery structure, which we explain by the lasting reputational differences in science, as well as the process of expansion and integration of HE systems. Furthermore, we demonstrate that centrality in national networks (coreness) is associated with organizational characteristics, reflecting that interlinking is motivated by access to resources and the status of the organizations concerned, and that national policies impact network structures by influencing the level of inequality in the distribution of resources and status. Finally, we show that, as an outcome of the core–periphery structure, the strength of ties between two HEIs is largely determined by their individual coreness, while the impact of distance is too small-scale to alter the network structure generated by organizational attributes. 相似文献

Participation in collection development by social science faculty at Tulane University decreased following the shift in primary responsibility for selection from the faculty to the library in 1987. A review of both the before and after, as well as the transition itself, identifies factors affecting this change and faculty participation in general. Among these factors are disciplinary information needs, the library's collection and collecting priorities, faculty members' attitudes towards the shift in responsibility and funds, and personal interest. 相似文献

ABSTRACT For many decades, the Department of Energy (DOE) has been an international leader in basic scientific and engineering research that utilizes geospatial science to advance the state of knowledge in disciplines impacting national security, energy sustainability, environmental stewardship, and associated basic research. However, the realized benefits from cross-cutting geospatial science contributions have fallen short of what they could have been with greater collaboration across the DOE complex, stronger emphasis on core geographic information science (GIScience) research and development to support advanced applications, increased strategic institutional support (e.g., for management of legacy data), and additional education and outreach concerning how geospatial science can benefit DOE programs and operations. We propose a vision for DOE's geospatial science based on expanded collaboration to address major national problems, additional advanced GIScience research and development, and a long-term strategy to better manage DOE's geospatial science resources (personnel, facilities, shared data, etc.). 相似文献

THE MARGINS OF JUSTICE ATTITUDES TOWARDS THE LAW AND THE LEGAL SYSTEM AMONG JEWS AND ARABS IN ISRAEL
Based on a national survey, attitudes towards the law and thelegal system of both Jews and Arabs in Israel were measured.Findings support the notion that Arabs as members of a minoritygroup express a higher degree of disobedience and express ahigher sense of injustice compared to the Jewish subjects. Findingstend to point to growing disobedience in the Israeli society,indicated by 22 percent of the Jewish subjects and 53 percentof the Arabs who express their readiness to take the law intotheir hands. 相似文献
