This study features the development and validation of a multidimensional scale for Perceived News Media Importance (PNMI), a concept pertaining to how much individuals personally value normative functions of political/public affairs journalism. Comprised of six different dimensions that represent the weight of what citizens deem to be desirable about news work, the PNMI concept exhibits the capacity to strengthen scholarly explanations about the public’s perceptions of the news media and related democratic outcomes. More specifically this research, which employs three data sets, is designed to (1) explicate the PNMI concept, (2) develop and validate a PNMI scale, (3) and explore PNMI’s predictive value relative to news media use and support for freedom of the press. Evidence of validity is confirmed with media trust, political media use, political interest, and ideology. Furthermore, PNMI is shown to be predictive of (a) mainstream and social media-based news use, as conditioned by perceptions of the press satisfactory performing normative functions, and (b) support for press freedoms. While the hypothesized PNMI model (as a higher order latent construct with six lower order dimensions) exhibits a sound model fit, a combined data set (total N=912) reveals that PNMI could also be treated as a multi-factor, lower-order latent construct. 相似文献

ABSTRACTWith reference to the current debate about a loss of trust in news media, journalism experts in practice and research often demand that journalists should concentrate on enhancing the quality of their reporting and hence focus on facts and evidences. Building on research on trust and credibility, we investigate how the use of different forms of evidences affects the credibility and quality evaluation of news stories, as well as the reading experience from the audience’s perspective. We conducted an online experiment to detect the influence of the presence of scientific sources, statistical information, and their visualization in an online article. Our findings indicate that these evidences increase the perceived credibility. At the same time, we found that adding scientific sources, statistical data and, visualizations to an article does not lessen its reading enjoyment but improves its perceived vividness in the view of news users. Further results and implications are discussed. 相似文献

ABSTRACT Digital platforms such as search engines and social media have become major gateways to news. Algorithms are used to deliver news that is consistent with consumers’ preferences and individuals share news through their online social networks. This networked environment has resulted in growing uncertainty about online information which has had an impact on news industries globally. While it is well established that perceptions of trust in news found on social media or via search engines are lower than traditional news media, there has been less discussion about the impact of social media use on perceptions of trust in the news media more broadly. This study fills that gap by examining the influence of social media as news sources and pathways to news on perceptions of the level of news trust at a country level. A secondary data analysis of a 26-country survey in 2016 and 2019 was conducted. The analysis revealed an increase in social media use for accessing news resulted in a decline in trust in news media generally across the globe. Higher levels of general mistrust in news were related to an increased use of sharing of news. This paper argues the use of social media for news is closely linked to the increase in news mistrust, which is likely to continue to rise as the number of people using social media to access news continues to grow. 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

Scientific news is one of the major resources that help the public to understand new scientific knowledge. The latest technology in research and development primarily utilizes English as the language of communication in academic journals and scientific communities. Compiled science news therefore has become a major agent for many non-Western societies to understand the latest technological developments. For this reason, this study aimed to investigate the meaningful change among transforming processes of imported science news from ‘original scientific research’ and ‘overseas news reports,’ to ‘domestic compiled science news.’ The research findings showed that scientific knowledge categories of compiled science news in Taiwan appeared to be apparently unbalanced, and the compiled skills present obvious weaknesses. Furthermore, more seriously compiled science news in Taiwan has continually suffered from the ‘double media distortion’ syndrome. The first distortion appeared from the ‘original scientific research’ to the ‘overseas news reports,’ and the second was from the ‘overseas news reports’ to the ‘domestic compiled science news.’ Such situations are very different from the Western world and could also be a common problem for all non-Western societies. 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

This study examines the mediating effects of information-processing strategies on the relationship between use of local news media, informational use of the Internet, and sources of social capital: interpersonal trust, reciprocity, and associational membership. Analyses of a telephone survey data (n = 546) of American adults show that even though local news media were influential, information-processing strategies were more powerful than attention in explaining learning from local news media about social norms at the individual level. These findings support the usefulness of the cognitive mediation model of information-processing behaviors in examining learning from local news media about social norms. Of the two strategies, elaborative processing played a more important role than active reflection in the mediating process. Informational use of the Internet had a significant and independent effect on associational membership, after demographic, structural anchoring, local media use, and information-processing measures were statistically controlled. 相似文献

This study investigates the relationship between adolescents' exposure to news, fictional police/crime shows, and reality police shows and their perceptions of the performance, distributive fairness, and procedural fairness of the police and the link with their overall attitude toward the police. Based on the literature, a hypothetical model of media influence is proposed and tested empirically in a cross-sectional survey of 356 Flemish adolescents. Watching reality shows was negatively related to adolescents' perceptions of how fairly the police exercise their authority. Exposure to the news negatively predicted respondents' perceptions of the distributive fairness of the police. Adolescents' beliefs about police performance were not related to media exposure. Exposure to fictional police shows did not significantly predict police perceptions. The results suggest that news and reality police shows play a small but significant role in adolescents' fairness perceptions of the police. 相似文献

In a post-truth era of fake news and alternative facts, it is relatively commonplace for people to question established authority and perhaps especially the surrogates of authority such as academic degrees and credentials that are often equated with elitism. However, some critics have questioned whether in rethinking standards, people have lost sight of the value of scientific and systematic research and the kind of expertise that comes from deep and extended study. This conceptual article offers an examination of the frame Authority is Constructed and Contextual from the ACRL Information Literacy Frameworks, and then provides a philosophical and a methodological approach for assessing authority. The article concludes with advice to instruction librarians to incorporate these approaches into their teaching. 相似文献

This study examines theoretical connections among three variables, each in its own way engendering profound political implications for the Chinese society today: news use, national pride, and political trust. We focused on the impact of ‘positivity bias in news’ and advanced a theoretical model on the basis of framing theory to address the dynamics of propaganda and its persuasive effects. Using data from the World Value Survey, we found: (1) news use in general, television news viewing in particular, was positively associated with political trust and national pride; (2) impact of news use on political trust disappeared once national pride was statistically controlled; and (3) intensity of national pride moderated the bivariate relationship between news use and political trust. The effect of party propaganda intended to consolidate political trust in China was contingent upon both one's affective ties to the state and the form of news media regularly consumed. 相似文献

The only long term trend data on trust in the American press comes from the General Social Survey (GSS). The erosion of trust in the press as measured by the GSS indicator is indisputable, but its implications for the functioning of American democracy depend on what, precisely, is being measured. In this study we use an experimental design embedded in a representative national probability sample to shed light on what people are thinking of when they say they trust or distrust the American press. Are they thinking about the sources they themselves use for news? The sources that are most popular with the population at large? An average of all possible media sources? We find that individuals express much greater trust in the press when they are asked to consider specific news sources than when they are asked to evaluate a generic news media. Our results suggest that an accessibility bias combined with the proliferation of news sources in recent years may lead individuals to think of distrusted sources when asked to answer generic media trust questions. We therefore argue that different measurement strategies are needed to successfully address trust in the press in the current news environment. 相似文献

This study addresses the question of the relationship betweenscientific knowledge and public attitudes toward science andtechnology. General work on cognitive schemas suggest that theseknowledge maps may have significant links to affect. A telephonesurvey of 2,000 Canadian adults was conducted and included abattery of knowledge items to test scientific cognition on basicscience concepts, to examine understanding of science processes,and to tap technological literacy. The survey also examinedattitudes toward science and scientists. Factor analysis of the attitude items resulted in two dimensions:trust in science and feelings of efficacy on science issues.A structural equation model was applied to certain demographicantecedent variables (education, exposure to science courses,age), the scientific literacy score, and to the attitude dimensionsof trust and efficacy. Findings demonstrated that scientificliteracy was positively correlated with attitudes of trust andfeelings of efficacy. These results were explained in termsof potential positive exposure to science in general in formalscience training (in schools) as well as to informal informationsources such as the media. 相似文献

A national survey of radio station general managers and news directors explored their demographic characteristics and stands on social issues. News directors’ support for a national health care program, their lack of support for unregulated business, their lack of trust in private enterprise to look out for the workers’ welfare, and their less negative view of labor unions may be explained through their own experience, as well as those of their newsroom employees. 相似文献

The complex web of information ranges from pure science to applied techniques to management policies. All are important, yet
have varying levels of accessibility and authority. Often the apex of the peer-reviewed journal article is considered the
most important level discouraging scientists and managers, especially those in developing countries, from populating the other
layers of the web that may be considered grey. We are particularly interested in how information produced in developing countries
fits into this information web. To do so, we focused on one topic, mangroves, using it as a means to exemplify the complexity
of the web of information and reveal publication patterns. Using search tools, we identified 2000–2005 mangrove-related publications
regarding Africa and India, analyzed them by author’s location and affiliation, publication format, and availability. Our
preliminary analysis suggests that grey literature remains difficult to discover, the peer-reviewed journal is the most popular
means of scientific communication, and open archives are just starting to have an impact on scholarly communication. The web
of information would be strengthened by improving the discovery of the grey literature through greater visibility and accessibility. 相似文献

Background: Health authorities, hospitals, commercial enterprises, and mass media all deliver health and medical communication in different forms. With such a vast amount of biomedical and clinical information available, any action to ensure the spread of clinically relevant news items is welcome. Objectives: This paper tries to define a new role for health science librarians in improving medical communication and reporting. Methods: Literature relating to the health and medical reporting is analysed to identify major difficulties encountered by health communicators. Results: There are two areas where health science librarians can develop new roles in health communication: (i) supporting journalists and health communicators in selecting sources and understanding scientific papers, and (ii) directly translating scientific information into news items, supplying a list of products in this direction (i.e. targeted newsletters, media releases, news items). New skills and competencies needed to cope with the new roles are described in detail in a suggested academic curriculum for health communicators. Conclusions: A better understanding of the mass media's needs can provide much needed support in the field of health communication. 相似文献
